Electrical connectors having a sealing element
View Patent ↗Provided for connectors intended for being coupled to a housing ( 1 ) defined in an electric junction box, with male terminals projecting from the bottom thereof and wherein between the body ( 9 ) of the connector and the bottom of the housing ( 1 ), a leak-tight seal ( 12 ) is arranged, the invention consists of situating between said seal ( 12 ) and the bottom of the housing ( 1 ), a separator ( 3 ) traversed by said male terminals, on which separator said seal ( 12 ) is in turn assembled, having die cuts ( 13 ) for said terminals and with slits ( 14 ) and ( 15 ) for pins ( 5 ) and ( 6 ) projecting from the plate ( 3 ) of the separator and which can be coupled inside the body ( 9 ), such that in the tightening of these elements, a deformation of the seal ( 12 ) is achieved against the separator ( 3 ), and accordingly with regard to the bottom of the housing ( 1 ), as well as with regard to the side wall of the latter, quite considerably facilitating the assembly of the seal ( 12 ), as this can be carried out on the stiff element constituted of the separator, outside of the housing ( 1 ), and the subsequent assembly of said ensemble inside the latter.
1. Sealed electrical connectors for coupling in housings operatively arranged in electric circuit boxes, particularly electrical connectors used in the automotive field having a seal positioned on a separator plate between a connector body and a connector body housing comprising:
a housing ( 1 ) having a pair of recesses ( 18 ) for attaching a connector body ( 9 ) operatively arranged in an electric circuit box;
a separator plate ( 3 ) having a upper side and a lower side operatively arranged in said housing ( 1 ), having a first pair of pins ( 5 ) and a second pair of pins ( 6 ) projecting from said upper side of said separator plate ( 3 ), and also having a pair of slits ( 4 ) suitably sized to allow passage of male terminals ( 19 );
a leak-tightness seal ( 12 ) operatively arranged on said upper surface of said separator plate ( 3 ) having a first pair of die cut openings ( 14 ) arranged to allow passage of said first pair of pins ( 5 ) therethrough, a second pair of die cut openings ( 15 ) arranged to allow passage of said second pair of pins ( 6 ) therethrough, and a pair of die cut openings ( 13 ) cooperatively arranged with said pair of slits ( 4 ) of said separator plate ( 3 ) allowing passage of male terminals ( 19 ) forming a seal around said openings ( 13 , 14 , 15 ) and between said separator plate ( 3 ) and said connector body ( 9 ); and
the connector body ( 9 ) having a first end having a pair of cylindrical necks ( 11 ) for introducing electrical wires to female connectors ( 10 ), and having a second end having perimetrical slit ( 16 ) for mounting housing ( 1 ), a pair of slits ( 8 ) for mounting said first pair of pins ( 5 ) and a pair of retention notches ( 17 ) cooperatively arranged to mount in said recesses ( 18 ) of housing ( 1 ).
2. Sealed electrical connectors according to claim 1 , characterized in that said first pairs of pins ( 5 ) is hollow and has notched side edges allowing pressure-coupling thereof in respective housings or said slits ( 8 ) of said connector body ( 9 ), and said second pair of pins ( 6 ) acts laterally on said female terminals ( 10 ) of said connector body ( 9 ), preventing deformations of said female terminals ( 10 ) and accidental disconnection.
3. Sealed electrical connectors according to claim 1 , characterized in that said connector body ( 9 ) incorporates a deep perimetrical slit ( 16 ) in which said housing ( 1 ) completely penetrates in the coupled position, said connector body ( 9 ) and said housing ( 1 ) being fixed by means of retention notches ( 17 ) in said perimetrical slit ( 16 ), and complementary recesses ( 18 ) in said housing ( 1 ).
