FIELD OF INVENTION
[0001] The present invention relates generally to an electrical cable assembly including
a shroud which surrounds the connection end of the cable connector. More particularly,
the present invention relates to a shroud for removable attachment to an electrical
connector.
BACKGROUND OF THE INVENTION
[0002] In interconnecting electrical cable, especially flat multiconductor cable, a pair
of mating electrical connectors are formed. One electrical connector typically includes
male insertion pins, while the other connector includes mating female sockets. Thus,
the pins of one connector may be inserted into the sockets of the mating connector.
In multiconductor cable connectors of the type shown herein, connection is typically
made by directly inserting the male pins into the female sockets. A certain degree
of manual dexterity is needed to assure that each of the pins is aligned with each
of the sockets prior to insertion, in order to minimize possible damage to the pins
upon insertion. This operation is further made difficult where one or the other of
the connectors is not readily accessible or is in such a tight location as to make
insertion difficult. This is the case where the connectors are used to connect components
on printed circuit boards or similar locations where interconnection space is not
typically abundant.
[0003] The art has seen the use of shroud members which surround pins which extend from
the printed circuit board. These shrouds serve to protect the pin array from damage
and further guide a mating connector into engagement with the pin array. Shrouds of
this type are shown in U.S. Patent No. 4,589,718. However, these shrouds are directly
supported on the printed circuit board surrounding pins which extend through the board.
These shrouds would not permit connection at a location spaced from the board surface.
Therefore, it is desirable to provide an electrical connector shroud which would provide
for ease of mating connection between two electrical cable connectors, either directly
onto a printed circuit board or spaced therefrom.
SUMMARY OF THE INVENTION
[0004] It is an object of the present invention to provide an electrical cable connector
shroud for facilitating intermateability of two electrical connectors.
[0005] It is a further object of the present invention to provide an electrical connector
shroud which will protect the connection end of electrical connector and further provide
a guide for interconnection of a pair of electrical connectors.
[0006] In the efficient attainment of these and other objects, the present invention provides
a shroud for an electrical connector having an interconnection surface including a
housing having an elongate bore therethrough. The housing includes means for engaging
the electrical connector and locking the connector in the shroud. The interconnection
surface of the electrical connector is disposed interiorly of the bore. The housing
further includes an interconnection channel partially coextensive with the central
bore of the housing for guiding and removably receiving another electrical connector
for mating electrical connection with the first.
[0007] In a more specific embodiment, the invention includes an electrical connection assembly
for terminating a multiconductor electrical cable. The assembly includes a housing
for accommodating one end of the cable. Plural electrical contacts are supported in
the housing for electrical engagement with the conductors of the cable. Portions of
the contacts define either a male or female electrical connection surface. A shroud
member having a central bore therethrough is removably attachable to the connection
housing for surrounding the interconnection surface of the housing. The central bore
of the shroud member is adapted for receipt of another connector housing thereby serving
as a guide and mating member for the two connector housings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0009] Referring to Figures 1-4, a flat multiconductor cable 10 is shown. Cable 10 includes
a plurality of elongate flat copper conductors 12 sandwiched by upper and lower layers
14 and 16 of insulative plastic. In the present illustrative embodiment insulative
layers 14 and 16 may be formed of Mylar or any similar plastic. One end of cable 10
is terminated in an electrical connector 20 shown additionally in Figures 2 and 4.
Connector 20 includes an insulative plastic housing 22 which is generally rectangular
in shape. Housing 22 supports, transversely thereacross a plurality of electrical
contacts 24. Connector 20 is constructed to have a one-to-one correspondence between
the number of electrical contacts 24 and the number of conductors 12 in cable 10.
Each conductor 12 is electrically connected to one of the electrical contacts 24 of
connector 20.
[0010] As shown in Figures 1 and 3, electrical contacts 24 can be either of the male insertion
pin type or the female socket type. The male insertion pin type contact includes an
outwardly extending male pin 26 which is designed for insertable interconnection into
the female socket (not shown) of the female connector of Figure 3. Connector housing
22 includes a plurality of transversely aligned apertures 28 which serve to captively
retain a portion of the electrical contacts to secure the contacts in housing 22.
[0011] As shown in Figures 2 and 4, the front edge of connector housing 22 defines an electrical
interconnection surface 29 which provides for mating interconnection. As shown in
Figure 2, male pins 26 extend outwardly from interconnection surface 29.
[0012] In Figure 4, interconnection surface 29 includes plural apertures 29a which permit
interconnection access to the female sockets (not shown).
[0013] Referring to Figure 5, the connection of the male and female connectors of Figures
1 and 3 is shown. Each of the interconnection surfaces 29 are in abutting engagement
thereby providing mating connection of the connector housings 22. Connection in this
manner provides electrical interconnection between each of the cables 10. It can be
seen that in order to facilitate proper connection of the male connector housing to
the female connector housing it is necessary that the pins 24 of one connector 20
be inserted into the apertures 29a of the other connector 20. While typically this
may be easily achieved by manually aligning the pins 24 with the apertures 29a there
may be instances where access to one or other of the connectors 20 is not readily
available.
[0014] Therefore, the present invention contemplates the use of a connector shroud 30 shown
in Figures 6-8. Shroud 30 is a generally rectangular plastic member having a central
bore 32 extending therethrough. Shroud 30 has a transverse dimension which is approximately
equivalent to the transverse dimension of connector housing 22 to receive the connector
housing therein as will be described in further detail hereinbelow. Shroud 30 includes
a plurality of facing inwardly directed projections 34 extending transversely along
the lower portion thereof. Projections 34 serve to lock connector 20 in shroud 30
by snapping into openings 28 of connector 20. As the shroud 30 is formed of a somewhat
resilient plastic these projections 34 will deform to snap into openings 28 upon insertion
of connector 20 through the bottom of shroud 30. In Figures 9 and 10, a male and female
connector are shown respectively positioned in shroud 30.
[0015] Referring again to Figures 6-8, the upper portion of shroud 30 includes on one side
thereof a centrally located channel 40 which opens toward the upper end of shroud
30. This channel is dimensioned to accommodate a protruding key 42 shown in Figures
3 and 4 which extends from connector housing 2 . This protruding key 42 provides for
polarized receipt of connector 20 in shroud 30. Shroud 30 also includes a pair of
mounting ears 44 which oppositely extend from the lower end of shroud 30. Mounting
ears 44 include a central aperture 45 therethrough which permit the shroud 30 to be
secured to a printed circuit board (not shown) or similar surface.
[0016] Referring now to Figure 11, the mating interconnection of two connectors 20 using
shroud 30 may be described. As shown in Figure 11, the connector which is to be secured
to the shroud 30 is male connector such as that shown in Figure 1. A female connector
such as that shown in Figure 3 will be matingly connected thereto. However, it can
be appreciated that female connector 20 could also be the shrouded connector for connection
with male connector. Male connector 20 is inserted into shroud 30 from the lower end
thereof. As described above, projections 34 of shroud 30 engage openings 28 of connector
20 to lock connector 20 into shroud 30. Bore 32 thereby forms a protective passageway
for the insertion of female connector 20 shown in Figure 2 therein. In order to provide
for polarized receipt of female connector 20 in shroud 30 it is necessary to mate
the protruding key 42 with channel slot 40 of shroud 30. This assures that the connection
will be properly polarized.
[0017] It can be seen that the shroud of the present invention serves to facilitate the
interconnection of one connector to the other mating connector. Further, where access
to the connectors may be hindered, blind insertion of one connector with the other
connector is facilitated by the use of shroud 30.
