Abstract
Abstract A multiconductor electrical connector socket comprising a conducting flange, having a permanently affixed ground conductor and plug receiving chamber, and a detachable molded insulating base containing circuit breakers. The detachable base has permanently affixed circuit breakers, conducting pins and buss strips in order to minimize the number of manual connection terminals. The connector is constructed so that when the flange and base are joined, an enclosure is formed, protecting the circuit breakers from damaging external forces.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
In an electrical connector socket for use in environments of exposure to weather and rough motion wherein power and control currents are transferred between said socket and a cable plug, the combination of a flange of conducting material having a receiving chamber formed therein, at least a portion of the bottom of said chamber being defined by a conducting segment, a ground pin fixed to said conducting segment and projecting into said chamber, a detachable insulating base mounted on said flange, a plurality of conducting pins mounted on said base and projecting into said chamber parallel to said ground pin, said insulating base having a recess formed therein, a plurality of circuit breakers disposed in said recess, means connecting one end of each of said circuit breakers to one of said conducting pins, and terminal connector means connected to the other end of each of said circuit breakers.
Claim 2
Dependent Claim
148 words
In an electrical connector socket for use in environments of exposure to weather and rough motion wherein power and control currents are transferred between said socket and a cable plug, the combination of a flange of conducting material having a receiving chamber formed therein, at least a portion of the bottom of said chamber being defined by a conducting segment, a ground pin fixed to said conducting segment and projecting into said chamber, a detachable insulating base mounted on said flange, a plurality of conducting pins mounted on said base and projecting into said chamber parallel to said ground pin, said insulating base having a recess formed therein, a plurality of circuit breakers disposed in said recess, means connecting one end of each of said circuit breakers to one of said conducting pins, and terminal connector means connected to the other end of each of said circuit breakers.
Claim 3
Dependent Claim
60 words
In an electrical connector socket as defined in claim 1, the combination wherein said means connecting one end of each of said circuit breakers to one of said conducting pins comprises a plurality of individual bus strips, said insulating base having a like plurality of second recesses formed therein, said bus strips being individually permanently affixed in said second recesses.
Claim 4
Dependent Claim
57 words
In an electrical connector socket as defined in claim 1, for use with a trailer said flange being adapted for mounting on said trailer, the combination wherein said insulating base includes spaced concentric walls formed on the surface thereof adjacent said flange, said walls, said base and said flange defining said recess and enclosing said circuit breakers.
Claim 5
Dependent Claim
59 words
In an electrical connector socket as defined in claim 1, the combination which includes a spring-loaded normally closed hinged cover mounted on said flange to cover said receiving chamber and a tongue formed on the inner surfaCe of said cover, said tongue being adapted to engage an element inserted in said receiving chamber upon opening of said hinged cover.
Claim 6
Dependent Claim
121 words
An electrical connector socket for a trailer comprising two major elements, a flange of conducting material and a base of insulating material for attachment to said flange, said flange having a circular recess formed in a surface thereof and said base having a generally matching recess formed in a surface thereof whereby a closed volume is formed by assembling said flange and said base together, a plurality of circuit breakers permanently fixed to said base and disposed in said closed volume, a plurality of conducting pins fixed in said base each said pin being electrically connected to one of said circuit breakers, said base having a cylindrical chamber formed therein, said conducting pins being disposed in parallel array in said chamber.
Claim 7
Dependent Claim
121 words
An electrical connector socket for a trailer comprising two major elements, a flange of conducting material and a base of insulating material for attachment to said flange, said flange having a circular recess formed in a surface thereof and said base having a generally matching recess formed in a surface thereof whereby a closed volume is formed by assembling said flange and said base together, a plurality of circuit breakers permanently fixed to said base and disposed in said closed volume, a plurality of conducting pins fixed in said base each said pin being electrically connected to one of said circuit breakers, said base having a cylindrical chamber formed therein, said conducting pins being disposed in parallel array in said chamber.
Claim 8
Dependent Claim
55 words
In an electrical connector socket for a trailer as defined in claim 5, the combination therewith of a segment of conducting material disposed at an end of said chamber and electrically connected to said flange and a ground pin mounted on said segment and extending into said chamber in parallel relationship to said conducting pins.
