[0001] The invention concerns an electrical connection device especially suited for use
in electric and electronic circuitry.
[0002] It is known that in wiring electric and electronic circuits, often electrical connections
are used consisting of a male device and a female device that are plugged together
by a push-sliding movement.
[0003] The use of this type of connections makes wiring quicker and moreover also enables
the various components to be easily disconnected whenever this need may arise.
[0004] These kinds of electrical connections are made in a variety of shapes and sizes depending
on the field of use and power being employed.
[0005] In the case of connections that are used in electronic control units for automobiles,
their construction is based on attempts to strike a balance between as miniaturised
a design as possible against the possibility of supporting high density currents and
thereby enabling them to carry as high a power as possible.
[0006] Since, as experts of the sector know, the current density that passes through an
electrical connection is directly proportional to the pressure involved in making
the connecting parts close against each other, constructor's efforts have been focused
on research for connections that create high pressures between the parts that make
up the junction.
[0007] There are known electrical connections consisting of a male device and a female device,
the latter having a first section that constitutes the actual electrical contact and
a second section working with the first and performing the task of creating a pressure
that ensures a mechanical contact between the male and female devices.
[0008] These types of electrical connections have the inconvenience of being somewhat complex
in construction and above all being rather bulky, to such an extent that they cannot
be used in any constructions that are applied to automobiles, where it is very important
that size is kept to a minimum, for instance electronic control units.
[0009] As an alternative to these kinds of connections and above all when limited sized
electrical connections are required, there is a widespread use of electrical connections
of the type illustrated in fig.'s 1 and 2 where the female device, generally indicated
by A, basically consists of a main body B which acts as a base for a basically longitudinal,
tubular collar C, whose walls form a socket D where the male contact device is plugged
in by a sliding movement, not illustrated in this instance. The tubular collar C includes
a U-shaped profiled section E and a laminar body F, which is set parallel to the profiled
section E and spaced apart from the facing sides Ea, Eb that define the actual profiled
section E.
[0010] The tubular collar C and the main body B are made from a single piece produced by
a boxed construction of blanked and bent sheet metal, where the laminar body F is
a single body with the main body B and has a free end Fa.
[0011] A ridge G on the laminar body F, facing socket D, presses against a male device,
not illustrated, when this is plugged into the actual socket D.
[0012] The laminar body F acts as a encased ledge and flexes upwards by bending along a
leverage line located on the main body B when the male device, as it is plugged in,
presses against the ridge G.
[0013] The electrical contact is guaranteed by the elastic force exerted by laminar body
F as ridge G presses against the male device after it has been plugged into the socket
D.
[0014] Female electrical connection devices produced according to the construction described
above, when on the one hand offer the advantage of being easy to manufacture and being
able to be produced in rather small sizes, on the other hand they have the inconvenience
of not being able to develop a sufficiently high pressure against the male device
that is plugged into them, at least not enough to allow the passage of intense currents.
As a consequence these electrical connections cannot be used to carry high levels
of electric power.
[0015] In particular, the aforementioned type of female electrical connection devices are
described in patents: US-3 836 947A, EP 0 694 992A, EP 0 353 330A, WO 9511532A, US
3 363 224A.
[0016] Particularly, US 3,836,947 discloses a femal electric receptacle for receiving and
making electrical contact with a male electrical terminal, wherein one side of the
receptacle is in the form of a resilient leaf spring which engages against a male
terminal, said leaf spring having a free terminal end. EP 0694992 discloses a female
terminal metal fixture with a resilient contact tongue, the deflection of which occuring
when a tab is inserted in said femal terminal, is stopped by bulged restrictive portions
provided on right and left walls of the female body.
[0017] In all the above patents the female connection has one or more contact blades that
have an end that is free to flex under the thrust of the male device as it is introduced.
[0018] Each blade, in addition to its end being free to flex, is also bent with the outside
curve set against the male device, improving its adherence and thereby guaranteeing
greater mechanical stability in the connection and favouring the passage of electric
current.
[0019] The inconvenience in the electrical connections described in the aforementioned patents
arises because the ends of the contact blades are free to flex and through time they
tend to lose their elasticity and consequently reduce the electrical efficiency of
the connection.
[0020] What's more the thrust against the male device that is plugged into the female connection
depends on the size of the curve made in the contact blade and since this tends to
alter with use, through time this causes a progressive decline in the quality of the
contact that it creates.
[0021] An additional inconvenience is that the flexible blades are basically equivalent
to booms anchored at one end, so they are only capable of creating a somewhat limited
contact pressure against the male device. Sometimes this pressure is increased by
fitting a stop bar over the blade at about halfway along its length, as can be seen
in patent US 3 836 947A, which, by its rigidity, increases the recoil force of the
flexible blade against the male device that is plugged in.
[0022] It is clear that this complicates the female electrical connection from a construction
standpoint and increases its production costs.
[0023] In some known executions, that are described in patents DE 4410951A1 and FR 2740266A,
to increase the rigidity of the flexible blade, a stiffening wall is set above it
made of a separate part to the body of the female connection, being held together
by means of special snap-in clasps made in the edges.
[0024] Even though these executions manage on the one hand to increase, and sometimes even
significantly, the rigidity of the flexible blade of the electrical connection and
thereby improve the quality of the electrical contact, on the other hand they have
the inconvenience of being more complex and more costly to produce.
[0025] This invention intends to overcome all of said limitations.
[0026] In particular the first scope of the invention is to produce a female electrical
connection device that develops, against the male device that is plugged into it,
a greater contact pressure than that achieved by known types of female electrical
connection devices being equal in size.
[0027] Another scope is that the contact pressure that the female electrical connection
device achieves with the male device that is plugged into it, principally relies on
the intrinsic mechanical characteristics of the material that makes up the actual
connection and not on its construction.
[0028] Another scope is that the connection device invention is made of a single body.
[0029] Another scope is that the connection device invention can be made in miniature sizes.
[0030] Last but not least, a scope is that the connection device invention substantially
maintains a constant elasticity through time.
[0031] Said scopes are achieved by the production of an electrical connection device that
in accordance with the main claim includes a main body which acts as a base for at
least one tubular collar that creates a longitudinal axis and that includes a profiled
section and a laminar body flexing elastically against said profiled section, the
two being spaced apart and having parallel lengths, suited to form a longitudinal
socket which can receive a male electrical connection device plugged in by a push-sliding
movement and is characterised in that the end of said laminar body is fixed to said
profiled section by anchoring devices so that at least its end is prevented from being
raised beyond said profiled section.
[0032] According to a preferred form of execution the main body and the tubular collar are
produced by a boxed construction from a single piece of blanked and bent sheet metal,
where the profiled section is U-shaped.
[0033] The laminar body is set parallel to the profiled section and is encased within and
spaced apart from the flat edges of the two facing sides that define the actual U-shaped
profiled section.
[0034] Halfway along the laminar body there is a ridged piece facing the inside of the profiled
section, which consists of a drawing suited to press against the surface of the respective
male contact device when this is plugged into the socket of the female electrical
connection device.
[0035] An advantage of the laminar body is that it is constructed as a boom anchored at
both ends and, when pressing against the male contact device, develops a greater pressure
than could be exerted by known types of electrical connection devices being equal
in size and where the laminar body has a ledge-type construction.
[0036] Therefore this execution allows, against known, equally sized female electrical connection
devices, the passage of a larger flow of current and thereby to carry a larger electric
power.
[0037] Said scopes and advantages shall be better explained during the description of a
preferred form of execution of the invention that refers to the attached diagrams,
where:
- fig. 1 illustrates the longitudinal section of a female electrical connection device
belonging to known technology;
- fig. 2 illustrates a cross-section along the plane II-II of the female electrical
connection device in fig. 1;
- fig. 3 illustrates an isometric view of the female electrical connection device invention;
- fig. 4 illustrates a longitudinal section of the electrical connection device in fig.
3;
- fig. 5 illustrates a front view of the electrical connection device in fig. 4;
- fig.'s 6, 7 and 8 illustrate a longitudinal section of the female electrical connection
device invention with its relevant male contact device in the disconnected position,
being plugged in and when plugged in, respectively;
- figures 9 to 13 illustrate variants in execution of the female electrical connection
device invention.
[0038] As can be seen in figures 3 to 5 the electrical connection device invention, generally
indicated by 1, includes a main body 2 which acts as a base for a tubular collar,
generally indicated by 3, that creates a longitudinal axis 4 and forms a socket 5
where the male contact device M is plugged in by a sliding and contrasting movement,
as can be seen in figures 6 to 8.
[0039] The central body 2 and the tubular collar 3, constitute a monolithic part since they
are made from a single piece of blanked and bent sheet metal that produces the boxed
construction of the connection device illustrated in fig. 3.
[0040] The monolithic production of the central body 2 and tubular collar 3 aid construction
of the connection against similar connection devices produced in several parts, as
for instance, those described in the aforementioned patents DE 4410951A1 and FR 2740266A.
[0041] In particular, the tubular collar 3 includes a U-shaped profiled section, generally
indicated by 6, made of flat sides 6a, 6b, 6c where faces 6a and 6c are two opposite,
parallel sides connected perpendicularly to the base 6b.
[0042] It is however clear that in different executions of the construction, the profiled
section may also have forms that differ from the U-shape described herein.
[0043] The top edges 6d, 6e of sides 6a, 6c respectively, are parallel and spaced apart
from a laminar body 7 set parallel to the profiled section 6 and encases within said
U-shaped profiled section.
[0044] The appropriate thickness of the laminar body 7 and suitable material used in its
construction make it flexible.
[0045] According to the invention said laminar body 7 is withheld at its end 7a by anchoring
devices suited to prevent at least the end 7a itself from being raised beyond said
profiled section 6.
[0046] In particular the anchoring devices consist of two tabs 8, 9 belonging to the side
faces 6a and 6c respectively of the profiled section 6, which are turned over the
laminar body 7 and prevent it from being raised beyond the profiled section 6.
[0047] In a different form of execution the profiled section 6 may have ribbing and/or grooving
suited to firmly anchor the end 7a of laminar body 7 so that any kind of movement
is prevented.
[0048] In another execution the end 7a of laminar body 7 may even be welded to the profiled
section 6.
[0049] As regards the laminar body 7, it can be seen in fig.'s 4 and 5 that halfway along
its length it has a drawing 10 having a convex surface 11 bent towards the inside
of the socket 5 which presses against the male contact device M when this is plugged
into the actual socket 5.
[0050] Longitudinal ribbing 14, 15 jutting up from the base face 6b of the profiled section
6 and opposing the drawing 10, increase the contact surface with the male contact
device M.
[0051] It can be seen, with reference to fig. 4, that the laminar body 7 presents itself
basically as a boom that has one end locked by the main body 2 and its opposite end
7a anchored to the profiled section 6 by tabs 8 and 9, contrary to contact devices
belonging to known technology described in the aforementioned patents, where the laminar
body is instead constructed as a locked boom with its end free and therefore basically
as a ledge.
[0052] When the male contact device M, as can be seen in figures 6 to 8, is plugged into
the socket 5 of the tubular collar 3, it presses against the convex surface 11 of
the drawing 10 and pushes the laminar body 7 upwards in the vertical direction indicated
in fig. 7 by arrow 12. In fact the distance 13 between the convex surface 11 and the
longitudinal ribbing 14, 15 made on base face 6b of the profiled section 6, is less
than the thickness 16 of the male device M.
[0053] When the male device M has been plugged in, as can be seen in fig. 8, the elastic
force that the laminar body 7 has accumulated by its deformation, generates force
F directed downwards, by which the convex surface 11, and as a result even the ribbing
14 and 15, create a contact with the male device M guaranteeing electrical continuity
between the parts in the junction.
[0054] It is clear that the level of force F depends on the deflection flexed by the laminar
body F, which in turn depends on the difference between thickness 16 of the male device
M and the distance 13 between the convex surface 11 and the longitudinal ribbing 14,
15 of the profiled section 6 which receives it.
[0055] In other words, by plugging in the male device M an inflection is created in the
laminar body 7 that by recoil gives rise to contact force F against the male M.
[0056] It is clear that in the connection invention, laminar body 7, that can be considered
as a boom anchored at both ends, against male device M creates a higher compression
force F than that exerted by the known type of connection illustrated in fig. 1 having
the same length and where the laminar body F flexes to create the same deflection.
[0057] What's more the elastic force developed by the laminar body 7 is created by the deformation
and is based on the intrinsic elasticity of the material it is made of and not by
any special configurations obtained by shaping that may alter in time thereby reducing
the contact's reliability.
[0058] Experimental tests performed on prototypes of the connection device invention where
the male M had a contrast of 0,1 mm. with the convex surface 11 of the drawing, have
given the means of measuring a force F value of 63 Newtons against 14 Newtons developed
by the type of connection illustrated in fig. 1 being equal in size and made of the
same materials.
[0059] The connection device invention can also be produced according to the different forms
of execution that are described below.
[0060] A variant in execution can be seen in fig. 9 where it is generally indicated by 20
and differs from the connection described earlier for the existence of a pair of tubular
collars 3 of the kind described earlier, equal in size or even different, arranged
at opposite ends of the main body 2.
[0061] According to another variant in execution illustrated in fig. 10, the electrical
connection device, generally indicated by 30, includes a single tubular collar 3 and
a male laminar body 31, arranged on opposite ends of the central body 2.
[0062] Another variant in execution is illustrated in fig. 11 where it can be seen that
the electrical connection device, generally indicated by 40, includes a tubular collar
3 and a clamp piece for electric cable, generally indicated by 41 and arranged on
opposite ends of the central body 2.
[0063] Another variant in execution of the invention is illustrated in fig. 12, where the
connection device is generally indicated by 50 and where it can be seen that it includes
a tubular collar 3 and a contact piece for printed circuits, generally indicated by
51, arranged on opposite ends of the central body 2. In particular the contact piece
for printed circuits 51 consists of a bar 52 having a prismatic section, bent towards
the longitudinal axis 53 of the tubular collar 3 and with narrowing 54 at its end.
[0064] According to another variant in execution, illustrated in fig. 13 and indicated by
60, that can exist on any of the variants in construction described herein, the anchoring
devices at the end 61a of the laminar body 61, consist of a ring 62 that anchors the
outside of end 61a of the laminar body 61 to the U-shaped profiled section 63.
[0065] The ring 62 can be attached or can belong to the profiled section 63.
[0066] From the above descriptions it can be understood that the electrical connection device
in all its execution variants included herein achieves the set scopes.
[0067] It is clear that according to its use, it may be produced in various sizes.
[0068] However the connection device invention has been described with reference to the
attached diagrams, it may also be constructed according to variants in execution that
have not been described herein, which nevertheless fall under the inventive concept
stated by the claims below and shall therefore be protected by this patent.
