Electrical connector

An electrical connector for connection to a post-type connector defined by an externally threaded tubular member having a smooth pin-receiving internal bore, said electrical connector comprising:

• a male pin connected to the end of a connector body;
• said connector body, at the end thereof remote from said pin, having a threaded bore therein;
• a terminal fastener having a threaded portion for threadedly engaging said threaded bore of said connector body and a head portion for securing an electrical terminal between said head portion and the end of said connector body, said head portion including at least one flat side surface for engaging inclined distal ends of a bifurcated terminal lug;
• an internally threaded collar mounted at the proximate end of said pin for free rotation, said collar being threadedly engagable with the external threads of the post-type connector;
• and
• said male pin including an enlarged diameter flange and a mounting stud axially extending from said flange, said stud received within a stud-receiving bore formed in said connector body, said flange spaced a selected distance from the pin end of the connector body, said collar having an axially extending cylindrical portion and an end wall having a bore therein, said collar mounted on said stud intermediate the corresponding end of said connector body and said flange.

• a male pin connected to the end of a connector body;
• an internally threaded collar mounted at the proximate end of said pin for free rotation, said collar being threadedly engagable with the external threads of the post-type connector;
• said connector body, at the end thereof remote from said pin, having a bore formed therein;
• said male pin including an axial bore therein which, together with the bore of said connector body, is adapted to receive a connector pin therein;
• and
• a threaded screw located in a threaded bore for securing said connector pin in said male pin axial bore.

• said connector body, at the end thereof remote from said pin, having a bore formed therein;
• said male pin including an axial bore therein which, together with the bore of said connector body, is adapted to receive a connector pin therein, and
• said male pin further including an enlarged diameter flange and a mounting stud axially extending from said flange, said stud received within a stud-receiving bore formed in said connector body, said flange spaced a selected distance from the pin end of the connector body, said collar having an axially extending cylindrical portion and an end wall having a bore therein, said collar mounted on said stud intermediate said pin end of said connector and said flange.
