Abstract

An electrical connector for connecting a tractor-trailer electrical cable to a truck tractor or a trailer electrical system includes a housing defining an interior space and having a mounting flange extending radially therefrom at a head end, at least one locking tab at the head end, and a wall dividing the interior space into a head end space and a foot end space, the wall having a plurality of holes in an array, a plurality of terminal pins secured against movement in the holes in the wall and extending from the foot end space into the head end space and a connector body having an outer wall configured to slide into the head end space of the housing.

First claim

What is claimed is:

1 . An electrical connector for connecting a tractor-trailer electrical cable to a truck tractor or a trailer, comprising:
a connector body having an outer wall defining an interior connector space and having a terminal support wall dividing the interior space into a socket space configured to receive a plug of an electrical cable and a terminal seal space, the terminal support wall having a plurality of holes in an array, the body having an external circumferential rib at a head end; a cap attached to the connector body by a hinge, the cap having a closed position and an open position and being spring biased toward the closed position, the cap having a lock member formed thereon.

2 . The electrical connector as claimed in claim 1 , comprising:
a housing defining an interior space and having a mounting flange extending radially therefrom at a head end, at least one locking tab at the head end, and a wall dividing the interior space into a head end space and a foot end space, the wall having an equal plurality of holes in an array as in the array in the connector body; a plurality of terminal pins secured against movement in the holes in the wall and extending from the foot end space into the head end space; wherein, the connector body is insertable in the head end space of the housing to a position with the terminal pins extending through the holes in the terminal support wall into the connector space and the at least one locking tab engaging the circumferential rib to secure the connector body in the housing.

3 . The electrical connector as claimed in claim 2 , comprising a catch formed on the hinge of the connector body and a second locking tab formed on the housing to engage the catch when the connector body is inserted in the housing.

4 . The electrical connector as claimed in claim 2 , comprising a membrane seal disposed in the foot end space of the housing, having an equal plurality of holes as the terminal support wall.

5 . The electrical connector as claimed in claim 1 , wherein the terminal pins have foot ends disposed in the foot end space of the housing and adapted for wire crimp connection to a wiring harness.

6 . The electrical connector as claimed in claim 1 , comprising a membrane seal disposed in the terminal seal space, the membrane seal having a plurality of holes equal to the plurality of holes in the terminal support wall.

7 . An electrical connector for connecting a tractor-trailer electrical cable to a truck tractor or a trailer, comprising:
a housing defining an interior space and having a mounting flange extending radially therefrom at a head end, at least one locking tab at the head end, and a wall dividing the interior space into a head end space and a foot end space, the wall having a plurality of holes in an array; a plurality of terminal pins secured against movement in the holes in the wall and extending from the foot end space into the head end space; a connector body having an outer wall configured to slide into the head end space of the housing, the connector body defining an interior socket space configured to receive a plug of an electrical cable, the connector body having a terminal support wall at a foot end of the connector body, the terminal support wall having an equal plurality of holes in the array to receive the plurality of terminal pins, and having an external circumferential rib at a head end; wherein, the connector body is insertable in the head end space of the housing to a position with the terminal pins extending through the holes in the terminal support wall into the socket space and the at least one locking tab engaging the circumferential rib to secure the connector body in the housing.

8 . The electrical connector as claimed in claim 7 , comprising a cap hingedly attached to the connector body at the head end, having a closed position closing the head end and having a locking wedge formed thereon.

9 . The electrical connector as claimed in claim 7 , comprising a catch formed on the hinge of the connector body and a second locking tab formed on the housing to engage the catch when the connector body is inserted in the housing.

10 . The electrical connector as claimed in claim 7 , comprising a membrane seal disposed in the foot end space of the housing, having an equal plurality of holes as the terminal support wall.

11 . The electrical connector as claimed in claim 7 , wherein the terminal pins have foot ends disposed in the foot end space of the housing and adapted for wire crimp connection to a wiring harness.

12 . The electrical connector as claimed in claim 7 , comprising a membrane seal disposed in the terminal seal space, the membrane seal having a plurality of holes equal to the plurality of holes in the terminal support wall.
