Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
122 words
In an electrical connector receptacle including a hollow housing having an end plate at one end and a closing cover at the opposite end, said end plate having a plurality of pin apertures extending therethrough, a plurality of male contact pins extending through said pin apertures and insertable from the outside of said end plate, cooperating means on said pins and pin apertures for limiting the extent to which said pins are inserted into said pin apertures, each of said pins having an annular groove, a locking plate positioned adjacent the inner wall of said end plate and slidable thereon, and means on said locking plate cooperating with the grooves in said pins for removably locking said pins in said pin apertures.
Claim 2
Dependent Claim
122 words
In an electrical connector receptacle including a hollow housing having an end plate at one end and a closing cover at the opposite end, said end plate having a plurality of pin apertures extending therethrough, a plurality of male contact pins extending through said pin apertures and insertable from the outside of said end plate, cooperating means on said pins and pin apertures for limiting the extent to which said pins are inserted into said pin apertures, each of said pins having an annular groove, a locking plate positioned adjacent the inner wall of said end plate and slidable thereon, and means on said locking plate cooperating with the grooves in said pins for removably locking said pins in said pin apertures.
Claim 3
Dependent Claim
40 words
