Electrical terminal connector

Claim 2

An electrical plug for use with mating electrical terminals comprising, a relatively rigid hollow housing having first and second open ends, a wall formed integrally with said housing and closing said first end of said housing, said wall defining aperture means therein communicating with said hollow housing, elongated electrical terminal means extending through said aperture means into said housing toward said second end of the housing, a unitary mass of resilient material moulded within and filling said hollow housing and firmly embedding and retaining said terminal means therein, said unitary mass of resilient material extending beyond said second end of said housing and through said aperture means beyond said first end of said housing and firmly embedding said wall therein, and flexible sealing means formed by the portion of said unitary mass of resilient terminal retaining material which extends beyond said second end of said housing for sealing said terminal means when the terminals are arranged in mating relationship with said elongated terminal means.

Claim 3

The plug of claim 1 wherein said sealing means comprises a resilient annular lip which surrounds said elongated terminal means adjacent the second end of the housing.

Claim 4

The plug of claim 1 including lug means carried externally of said housing for maintaining said elongated terminal means in mating relationship with the terminals.

Claim 5

The plug of claim 1 wherein said unitary mass of material is polyvinyl chloride.

Claim 6

A connector comprising in combination, a terminal block comprising a hollow housing, a substantially rigid wall at one end of said block housing carrying first terminal means, a plug comprising a second rigid hollow housing adapted to be inserted into said block housing adjacent to but spaced slightly from the wall of said block housing, said second rigid housing being open at both ends, a wall in said second rigid housing and closing a first of said open ends, said wall defining aperture means therein, second terminal means extending into said second housing through said aperture means and into mating relationship with said first terminal means when said second housing is inserted into said block housing, a unitary mass of resilient material moulded within and filling said second rigid housing and firmly embedding and retaining said second terminal means therein, said resilient material extending through said aperture means beyond said first end of said housing firmly embedding said wall therein and beyond the other open end to form a sealing lip between the second housing and said substantially rigid wall of the block housing, and lug means on one of said housings cooperating with the other of said housings for retaining the housings in their inserted relationship.

Claim 7

A connector comprising in combination, a terminal block comprising a hollow housing, a substantially rigid wall at one end of said block housing carrying first terminal means, a plug comprising a second rigid hollow housing adapted to be inserted into said block housing adjacent to but spaced slightly from the wall of said block housing, said second rigid housing being open at both ends, a wall in said second rigid housing and closing a first of said open ends, said wall defining aperture means therein, second terminal means extending into said second housing through said aperture means and into mating relationship with said first terminal means when said second housing is inserted into said block housing, a unitary mass of resilient material moulded within and filling said second rigid housing and firmly embedding and retaining said second terminal means therein, said resilient material extending through said aperture means beyond said first end of said housing firmly embedding said wall therein and beyond the other open end to form a sealing lip between the second housing and said substantially rigid wall of the block housing, and lug means on one of said housings cooperating with the other of said housings for retaining the housings in their inserted relationship.

Claim 8

The connector of claim 5 including a plurality of grooves formed on said sealing lip, said grooves contacting said wall of the block housing when said second rigid housing is inserted in said block housing.

Claim 9

The connector of claim 5 wherein said block housing includes a plurality of sockets, at least one of said sockets and plugs including means to allow insertion of only selected ones of said plugs into selected ones of said sockets.
