FIELD
[0001] The present disclosure relates to a high voltage connector comprising an inner terminal
portion and an outer housing, and to a method for providing a connection via a high
voltage connector.
BACKGROUND
[0002] In high voltage connections, a plug connector is usually connected to a header assembly
comprising a suitable interface by the use of a direct locking and optionally a device
for supporting the connection. During the assembly of an electric or hybrid vehicle
requiring high voltage connections, however, an operator may face difficulties when
aligning and/or correctly polarizing the plug connector with respect to the header
assembly, e.g. due to the rigidity of the vehicle's harness. Moreover, a strain relief
function for a cable connected to the plug connector and/or a connector position assurance
(CPA) function are usually provided by separate parts independently from the plug
connector. This enhances the number of parts required for providing a safe high voltage
connection.
[0003] Accordingly, there is a need to have a high voltage connector and a method for providing
a high voltage connection which are able to facilitate the assembly of the connection,
e.g. in an automotive environment.
SUMMARY
[0004] The present disclosure provides a high voltage connector and to a method for providing
a high voltage connection according to the independent claims. Embodiments are given
in the subclaims, the description and the drawings.
[0005] In one aspect, the present disclosure is directed at a high voltage connector which
comprises an inner terminal portion, an outer housing, and an inner carrier element
disposed between the inner terminal portion and the outer housing such that the inner
terminal portion is rotatable with respect to the outer housing. Further, the high
voltage connector comprises a locking assembly which allows for a rotation of the
inner terminal portion in a pre-lock condition of the high voltage connector and which
prevents the rotation of the inner terminal portion in a final lock condition of the
high voltage connector.
[0006] The inner terminal portion is configured to accommodate or to be connected to a high
voltage cable or a similar equipment. The high voltage connector may be configured
to be connected to a header assembly, e.g. in order to connect a harness of a vehicle
to such a header assembly.
[0007] Due to the inner carrier element being provided between the inner terminal portion
and the outer housing, the inner terminal portion and the outer housing are freely
rotatable with respect to each other in the pre-lock condition of the high voltage
connector. Therefore, the outer housing of the high voltage connector may be properly
aligned with respect to the header assembly to which the high voltage connector is
to be connected due to the free rotation of the outer housing with respect to the
inner terminal portion. This free rotation facilitates or eases the assembly of the
high voltage connector e.g. when providing a connection to the header assembly for
a vehicle harness. As such, the effort for mounting the high voltage connector, e.g.
due to polarization constraints, may be reduced.
[0008] Moreover, the inner carrier element may be rotationally fixed either with the inner
terminal portion or with the outer housing in order to provide the rotation of the
inner terminal portion and the outer housing with respect to each other in the pre-lock
condition. The selection of the portion or element to which the inner carrier element
is rotationally fixed may depend on the detailed inner structure of the high voltage
connector and its intended use.
[0009] According to an embodiment, the high voltage connector may further comprise a retainer
element configured to be engaged with the outer housing. The locking assembly may
include the outer housing and the retainer element which may be moveable with respect
to each other in order to provide the pre-lock condition and the final lock condition.
The final lock condition may be achieved when the outer housing and the retainer element
are engaged with each other. For example, the retainer element may be slidable with
respect to the high voltage connector in an axial direction along a centerline of
the high voltage connector in order to get into an engagement position with respect
to the outer housing to achieve the final lock condition. Since the locking assembly
may include two elements only, i.e. the outer housing and the retainer element being
movable with respect to each other, the high voltage connector may require a small
number of parts only in order to provide a safe high voltage connection. The small
number of parts may reduce the cost for manufacturing the high voltage connector.
[0010] The retainer element may include a latch portion being engaged with the outer housing
for providing the final lock condition. For example, an area or surface connected
to the latch portion may be pressed by an operator of the high voltage connector in
order to transition the locking assembly from the pre-lock condition to the final
lock condition. In this way, the retainer element may slide in the axial direction
along the centerline of the high voltage connector in order to arrive at the final
lock condition. Hence, the high voltage connector may achieve the final lock condition
without the requirement of an additional latch, i.e. in addition to the retainer element.
[0011] The retainer element and the outer housing may provide a connector position assurance
(CPA) for the high voltage connector. The connector position assurance may ensure
the proper polarization and may prevent a mechanical and/or electrical disconnection
during an adverse driving condition of a vehicle, for example, when the high voltage
connector is connected to a header assembly.
[0012] The high voltage connector may further comprise a strain relief element, and the
retainer element may include a portion which may be engaged with the strain relief
element in the final lock condition. Therefore, the retainer element may be regarded
as a multi-function retainer providing different functionalities, i.e. locking the
high voltage connector, providing the connector position assurance and providing a
strain relief, at the same time. Since one part is required for different functions
only, the total number of parts or elements required for the high voltage connector
may be further reduced which reduces the total cost for the high voltage connector.
In addition, the effort for providing the high voltage connection may also be reduced
since the retainer element has to be moved only in order to provide different functions
simultaneously.
[0013] The strain relief element may include flexible arms which may be configured to surround
a cable which is to be connected to the inner terminal portion. Therefore, the strain
relief may be provided uniformly in a circumferential direction of the cable and the
high voltage connector. By this means, the safety of the high voltage connection may
be improved.
[0014] The retainer element may further include a protrusion portion which may engage with
the flexible arms of the strain relief element in the final lock condition. For example,
the protrusion portion of the retainer element may press each of the flexible arms
of the strain relief element against the cable connected to the inner terminal portion.
[0015] According to a further embodiment, the high voltage connector may further comprise
an outer carrier element being connected to the outer housing, and a shield element
may be disposed between the outer carrier element and the inner carrier element. The
shield element may improve the electromagnetic capability (EMC) performance of the
high voltage connection. Due to the connection to the outer housing, the outer carrier
element may also be rotatable with respect to the inner terminal portion. The outer
carrier element may be isolated with respect to the outer housing.
[0016] The inner terminal portion may be fixed to the inner carrier element, and the inner
terminal portion and the inner carrier element may be snapped to the outer carrier
element by at least one outer engagement element such that a stop may be provided
for the rotation of the inner terminal portion with respect to the outer housing.
For this embodiment, a stable mechanical connection may be provided for the inner
elements with respect to the outer carrier. The rotation of the inner terminal portion
may be restricted with respect to the outer housing, but is still enabled generally.
[0017] A high voltage interlock (HVIL) shunt may be mounted to the outer carrier element.
This may further improve the safety of the high voltage connection. In addition, the
outer carrier element may include a protruding portion in order to protect the high
voltage interlock (HVIL) shunt for the high voltage connector.
[0018] The inner terminal portion may be rotatable with respect to the outer housing in
a clockwise direction and in a counterclockwise direction. By this means, a rotation
for about 360 degrees may be provided for the inner terminal element with respect
to the outer housing. This may enhance the flexibility of the high voltage connector
for a connection to a header assembly.
[0019] In another aspect, the present disclosure is directed at a method for providing a
connection via a high voltage connector. The high voltage connector comprises an inner
terminal portion, an outer housing, an inner carrier element disposed between the
inner terminal portion and the outer housing, and a locking assembly. According to
the method, the outer housing is adjusted with respect to the inner terminal portion
to provide a pre-lock condition of the high voltage connector in which the inner terminal
portion is rotatable with respect to the outer housing via the inner carrier element.
In the pre-lock condition, the outer housing is rotated with respect to the inner
terminal portion until the outer housing is in a desired alignment position with respect
to a header assembly to which the high voltage connector is to be connected. Thereafter,
the outer housing is adjusted with respect to the inner carrier element and to the
terminal portion in order to provide a final lock condition of the high voltage connector
in which the inner terminal portion is rotationally fixed with respect to the outer
housing.
[0020] As such, the method includes steps which are carried out by using the high voltage
connector as described above. Therefore, the benefit, the advantages and the disclosure
for the high voltage connector are also valid for the method according to the disclosure.
[0021] According to an embodiment, the high voltage connector may further comprise a retainer
element. The retainer element may be moved with respect to the outer housing in order
to provide a respective transition between the pre-lock condition and the final lock
condition. For example, the retainer element may slide in an axial direction along
a centerline of the high voltage connector in order to provide the transitions. Since
only one part or element may be moved for the transition between the pre-lock condition
and the final lock condition, providing the high voltage connection may be facilitated,
and the effort for the connection may be reduced.
[0022] The retainer element may include a portion which is pressed for the transition from
the pre-lock-condition to the final lock condition. The high voltage connector may
also include a so-called "press-2 latch" function which is an intermediate locking
condition of the retainer element before arriving at the final lock condition. In
this intermediate locking condition, the high voltage interlock (HVIL) shunt is disconnected
such that an operator may be aware that no power connection is provided in this condition.
[0023] Moreover, pressing the portion of the retainer element may cause an engagement of
a latch of the outer housing which may also entail a disconnection of the high voltage
interlock (HVIL) shunt. The further movement of the retainer element may provide a
connector position assurance of the high voltage connector. Hence, one method step
may be required only in order to perform several different functions within the high
voltage connector.
[0024] According to a further embodiment, the high voltage connector may further comprise
a strain relief element which may be engaged with the retainer element simultaneously
with the transition from the pre-lock condition to the final lock condition. Hence,
a further function, i.e. the strain relief function, may be provided by the engagement
of the retainer element with the strain relief element when the final lock condition
is achieved. This may reduce the number of parts required for the high voltage connector
and the effort for providing a safe high voltage connection.
[0025] The strain relief element may include flexible arms which may be compressed by the
retainer element when the high voltage connector transitions to the final lock condition.
Compressing the flexible arms may further enhance the safety of the high voltage connection
by compressing a cable which is to be connected to the high voltage connector.

DETAILED DESCRIPTION
[0027] Fig. 1 depicts a high voltage connector 100 according to the disclosure in a perspective
view. The high voltage connector 100 includes an inner terminal portion 110 which
is connected to an inner carrier element 120. The high voltage connector 100 further
includes an outer housing 130 and a retainer element 140. In addition, an outer carrier
element 150 is connected to the outer housing 130. The inner carrier element 120 and
the outer carrier element 150 are made of an insulating material.
[0028] For the high voltage connector 100, a centerline 160 is shown which defines an axial
direction for the high voltage connector 100. In order to provide a high voltage connection,
the high voltage connector 100 is moved along the axial direction as indicated by
the arrow 170 in order to be connected to a header assembly (not shown).
[0029] As will be explained in detail below, the inner terminal portion 110 and the inner
carrier element 120 are rotatable with respect to the outer housing 130, i.e. in a
clockwise direction and in a counterclockwise direction as indicated by the arrows
180. More precisely, the inner carrier element 110 is rotatable with respect to the
outer housing 130 as long as the high voltage connector 100 is in a pre-lock condition
(see also Fig. 5). By the rotation of the outer housing 130 and the outer carrier
element 150 with respect to the inner terminal portion 110, a proper alignment of
the high voltage connector 100 is provided via a protruding portion 152 of the outer
carrier element 150 with respect to the header assembly (not shown) to which the high
voltage connector 100 is to be connected.
[0030] The proper alignment of the outer housing 130 and the outer carrier element 150 due
to the rotation with respect to the inner terminal portion 120 facilitates the installation
of the high voltage connector 100 in order to provide the high voltage connection.
In a vehicle environment, for example, the high voltage connector 100 may be connected
to a harness of a vehicle which would restrict the movability and flexibility of the
high voltage connector 100 if the inner terminal portion 110 were not rotatable with
respect to the outer housing 130.
[0031] Fig. 2 depicts a cross-sectional view of the high voltage connector 100 as shown
in Fig. 1. The inner terminal portion 110 of the high voltage connector 100 is connected
to a cable 210 which includes a shield braid 215 at its outer circumference. As can
be recognized on the left side of Fig. 2, the inner carrier element 120 is rotationally
fixed to the inner terminal portion 110 via the engagement elements 205 which are
located in corresponding openings of the inner terminal portion 110. As indicated
by the gap between the inner carrier element 120 and the outer carrier element 150,
the inner terminal portion 110 and the inner carrier element 120 are rotatable with
respect to the outer carrier element 150. Since the outer carrier element 150 is fixed
to the outer housing 130, the inner terminal portion 110 and the inner carrier element
120 are rotatable also with respect to the outer housing 130.
[0032] Different shields are provided between the outer elements, i.e. the outer housing
130 and the outer carrier element 150, on one hand and the inner elements, i.e. the
inner terminal portion 110 and the inner carrier element 120, on the other hand. These
shields include a front shield 220, a rear shield 224 and a recovery shield 226. Moreover,
different seals are provided for electric isolation. The seals include an interface
seal 230 which is disposed between the outer housing 130 and the outer carrier element
150, whereas a cable seal 232 is disposed between the outer housing 130 and the cable
210.
[0033] In order to stabilize the high voltage connector 100 mechanically and regarding its
water tightness, a spacer 240 is also disposed between the outer housing 130 and the
cable 210. In addition, an outer or inner ferrule 242 is located around the recovery
shield 226, wherein the outside option is shown in the figures, and the shield braid
215 of the cable 210 in order to support the fixation of the cable 210 at the high
voltage connector 100.
[0034] The high voltage connector 100 further includes a strain relief element 250 which
has a plurality of flexible arms 252 surrounding the cable 210. The retainer element
140 includes a protrusion 142 which is able to be engaged with the strain relief element
250 in order to press the flexible arms 252 against the cable 210. By this means,
a strain relief function is provided for the cable 210.
[0035] Moreover, the high voltage connector 100 includes a high voltage interlock (HVIL)
shunt 260 which is disposed close to the outer carrier element 150 as a further safety
feature of the high voltage connector 100. The high voltage interlock (HVIL) shunt
260 is disposed on the inner side of the protruding portion 152 of the outer carrier
element 150. As mentioned above the protruding portion 152 ensures a proper alignment
of the high voltage connector 100 with respect to the header assembly (not shown).
[0036] In the illustration of Fig. 2, the high voltage connector 100 is still in a so-called
pre-lock condition in which the retainer element 140 is not latched yet with the outer
housing 130 in order to allow for a rotation between the outer housing 130 and the
inner terminal portion 110. The pre-lock condition of the high voltage connector 100
and its transition to a final lock condition will be discussed in detail in context
of Figs. 5 and 6 below.
[0037] Figs. 3 and 4 show details of the assembly of the high voltage connector 100, i.e.
details regarding the connection of the inner terminal portion 110, the inner carrier
element 120, the outer carrier element 150 and the outer housing 130. As already mentioned
above in context of Fig. 2, the inner carrier element 120 is fixed to the inner terminal
portion 110 via the engagement elements 205 being located in corresponding openings
of the inner terminal portion 110.
[0038] As indicated by the circles 310 in Fig. 3, the inner carrier element 120 is further
provided with outer engagement elements 320 in order to be snapped to the outer carrier
element 150. Nevertheless, a rotation of the inner carrier element 120 together with
the inner terminal portion 110 is possible with respect to the outer carrier element
150 and therefore with respect to the outer housing 130 around the center line 160
(see Fig. 1) of the high voltage connector 100.
[0039] As indicated by the ovals 410 in Fig. 4, the outer carrier element 150 is located
and snapped, i.e. fixed, to the outer housing 130. Due to the snapping connections
as described in context of Figs. 3 and 4, a proper mechanical connection is provided
between the inner terminal portion 110, the inner carrier element 120, the outer carrier
element 150 and the outer housing 130. In spite of this, the inner terminal portion
110 together with the inner carrier element 120 is still rotatable with respect to
the outer carrier element 150 and the outer housing 130 if the high voltage connector
100 is in the pre-lock condition as shown in Fig. 5.
[0040] As mentioned above in context of Fig. 2, the protrusion 142 of the retainer element
140 is still not engaged with the strain relief element 250 if the high voltage connector
100 is in the pre-lock condition as shown in Fig. 5. Therefore, the flexible arms
252 of the strain relief element 250 still allow for a rotation of the outer housing
130 with respect to the inner terminal portion 110 and therefore, conversely, for
a rotation of the cable 210 with respect to the outer housing 130.
[0041] Moreover, the retainer element 140 further includes a blocking and header activation
element 144 for positioning the retainer element 140 with respect to the outer housing
130. This is indicated by the oval 510. The retainer element 140 further includes
a latch 146 which is still out of engagement in the illustration of Fig. 5, i.e. in
the pre-lock condition of the high voltage connector 100. Moreover, the retainer element
140 also includes a portion 148 which provides a so-called "press-2 latch" function"
which is an intermediate locking condition of the retainer element 140 before arriving
at the final lock condition. In this intermediate locking condition, the high voltage
interlock (HVIL) shunt 260 is disconnected such that an operator is aware that no
power connection is provided in this condition.
[0042] By moving the retainer element 140 with respect to the outer housing 130, the high
voltage connector 100 is transitioned from the pre-lock condition to the final lock
condition as shown in Fig. 6. The blocking and header activation element 144 also
contributes to a connector position assurance (CPA) function for the high voltage
connector 100 with respect to the header assembly in the final lock condition. The
connector position assurance ensures the proper polarization and prevents a mechanical
and/or electrical disconnection during an adverse driving condition of a vehicle when
the high voltage connector 100 is connected to the header assembly.
[0043] After a proper alignment of the high voltage connector 100 with respect to the header
assembly (not shown) which is provided by the rotation of the outer housing 130 with
respect to the inner terminal portion 110, the retainer element 140 is shifted along
the centerline 160 (see Fig. 1) of the high voltage connector 100, i.e. to the left
in the illustration of Figs. 5 and 6, such that the latch 146 is engaged with the
outer housing 130 of the high voltage connector 100. Simultaneously, the flexible
arms 252 of the strain relief element 250 are pressed against the cable 210 by the
engagement of the protrusion 142 of the retainer element 140 with the strain relief
element 250. Due to the pressing of the flexible arms 252 against the cable 210, any
rotation between the outer housing 130 and the inner terminal portion 110 of the high
voltage connector 100 is disabled, and simultaneously a strain relief is provided
for the cable 210. At the same time, the press-2 latch function blocks the retainer
element 140 such that the inner terminal portion 110 is fixed with respect to the
outer housing 130.
[0044] Fig. 7 shows a flow diagram illustrating a method 700 for providing a connection
via a high voltage connector. The high voltage connector may include an inner terminal
portion, an outer housing, an inner carrier element disposed between the inner terminal
portion and the outer housing, and a locking assembly.
[0045] At 702, the outer housing may be adjusted with respect to the inner terminal portion
to provide a pre-lock condition of the high voltage connector in which the inner terminal
portion may be rotatable with respect to the outer housing via the inner carrier element.
At 704, the outer housing may be rotated with respect to the inner terminal portion
in the pre-lock condition until the outer housing is in a desired alignment position
with respect to a header assembly to which the high voltage connector is to be connected.
At 706, the outer housing may be adjusted with respect to the inner carrier element
and to the terminal portion to provide a final lock condition of the high voltage
connector in which the inner terminal portion is rotationally fixed with respect to
the outer housing, e.g. by a retainer element being positioned in the final lock condition.
[0046] According to various embodiments, the high voltage connector may further comprise
a retainer element, and the retainer element may be moved with respect to the outer
housing in order to provide a respective transition between the pre-lock condition
and the final lock condition.

is pressed for the transition from the pre-lock condition to the final lock condition.

element simultaneously with the transition from the pre-lock condition to the final
lock condition.

arms which may be compressed by the retainer element when the high voltage connector
transitions to the final lock condition.
[0050] According to various embodiments, a high voltage connector may comprise an inner
terminal portion, an outer housing, an inner carrier element disposed between the
inner terminal portion and the outer housing such that the inner terminal portion
is rotatable with respect to the outer housing, and a locking assembly which may allow
for a rotation of the inner terminal portion in a pre-lock condition of the high voltage
connector and which may prevent the rotation of the inner terminal portion in a final
lock condition of the high voltage connector.
[0051] According to various embodiments, the high voltage connector may further comprise
a retainer element configured to be engaged with the outer housing, and the locking
assembly may include the outer housing and the retainer element which may be movable
with respect to each other in order to provide the pre-lock condition and the final
lock condition.
[0052] According to various embodiments, the retainer element may include a latch portion
being engaged with the outer housing for providing the final lock condition.

a strain relief element, and the retainer element includes a portion which is engaged
with the strain relief element in the final lock condition.
[0055] According to various embodiments, the strain relief element may include flexible
arms which may be configured to surround a cable which is to be connected to the inner
terminal portion.
[0056] According to various embodiments, the retainer element may include a protrusion portion
which engages with the flexible arms of the strain relief element in the final lock
condition.
[0057] According to various embodiments, the high voltage connector may further comprise
