Modularized universal pin and sleeve electrical connector
First Claim
1. An environmentally sealed, hand assemblable, electrical connector of the pin and sleeve type including a pair of hollow interfittable angularly oriented shell members, a pair of resilient insert members coaxially and interchangably received within either of the shell members and having aligned terminal receiving cavities therein and index means allowing selective mounting of each insert member into its respective shell member in one of a plurality of mating orientations,two sets of elongated mateable terminals, each set being mounted in the cavities of one of the insert members,terminal locking means operable to lock said terminals in said cavities, andbackshell means matingly received by one of said shell members which cooperates therewith for compressing said insert member in order to create an environmental seal between said shell member and said insert member,the improvement comprising:
- each insert member having a modular construction and including two mating segments with aligned openings to define each cavity, one of the segments having an extension portion nestably receivable within axecess in the other segment for forming an environmental seal therebetween, interengaging means cooperable and formed at the nestably related juncture of the segments for maintaining the segments in mating relationship by blocking separation thereof in the axial direction of said openings, and at least one of the segments having a rupturable diaphragm member formed across each of the terminal cavities, to provide sealing engagement with terminals inserted into the cavities, said openings of said one segment passing through said extension portion.

Abstract
A modularized pin and sleeve type electrical connector for both portable and stationary industrial applications, the connector having an interfitting plug shell and receptacle shell, male and female inserts which can be interchangeably used therewith, and assorted backshell components. Diaphragms formed across the terminal cavities carried by the inserts act to seal off the cavities, both before and after being pierced by terminals inserted therein. The inserts are multipiece and have conical locking structure formed about the terminal cavities which provide low insertion and high withdrawal forces to the terminals inserted therein. Both the interchangeable inserts as well as the plug and receptacle shells have keying components which permit the inserts to be rotatably positioned in the shells as the connector is assembled in the field, to result in a desired angular mating orientation for the connector. Each of the various backshell components operates to compress the associated insert into its mating shell thereby effecting a proper environmental seal of the insert and terminals. The backshell components for either portable or stationary applications will fit both the plug shell and the receptacle shell.
