Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
224 words
An electrical connector comprising: a body within which a plurality of extendable electrically conductive pins are housed, said body having a front end portion and a rearwardly extending portion; a plurality of electrically conductive plates mounted at the front end portion of said body, each of said plates having apertures therein; a plurality of pairs of electrically conductive pins slidably mounted in said body so as to be movable between a retracted position behind said plates and an extended functional position extending frontwardly through respective apertures of said plates, said pins having a rear portion, the rear portion of said pins being in electrical contact with a respective plate of said plurality of plates when said pins are in the extended functional position; a rotatable masking means mounted in front of said plates, said masking means having opposed windows therein so as to allow the selective exposure and extension of a pair of said electrically conductive pins; a plurality of electrical terminals at the rearwardly extending portion of said body; a plurality of electrical connections extending through said body, each of said connections extending from a respective terminal of said plurality of terminals through said body to a respective plate of said plurality of plates; and a casing receiving said body, said casing having a rearwardly extending socket capable of receiving an electrical cable.
Claim 2
Dependent Claim
224 words
An electrical connector comprising: a body within which a plurality of extendable electrically conductive pins are housed, said body having a front end portion and a rearwardly extending portion; a plurality of electrically conductive plates mounted at the front end portion of said body, each of said plates having apertures therein; a plurality of pairs of electrically conductive pins slidably mounted in said body so as to be movable between a retracted position behind said plates and an extended functional position extending frontwardly through respective apertures of said plates, said pins having a rear portion, the rear portion of said pins being in electrical contact with a respective plate of said plurality of plates when said pins are in the extended functional position; a rotatable masking means mounted in front of said plates, said masking means having opposed windows therein so as to allow the selective exposure and extension of a pair of said electrically conductive pins; a plurality of electrical terminals at the rearwardly extending portion of said body; a plurality of electrical connections extending through said body, each of said connections extending from a respective terminal of said plurality of terminals through said body to a respective plate of said plurality of plates; and a casing receiving said body, said casing having a rearwardly extending socket capable of receiving an electrical cable.
Claim 3
Dependent Claim
47 words
An electrical connector according to claim 1, wherein the rearwardly extending portion of said body comprises a wall portion having said electrical terminals emerging therefrom and a platform located below said wall portion, said platform carrying a clamping means capable of securing an electrical cable end part.
Claim 4
Dependent Claim
22 words
An electrical connector according to claim 1, wherein means for securing said electrically conductive pins in their extended functional position are provided.
Claim 5
Dependent Claim
21 words

Claim 6
Dependent Claim
24 words
An electrical connector according to claim 4, wherein one of said plates is a live plate and the other plate is a neutral plate.
Claim 7
Dependent Claim
36 words
An electrical connector according to claim 5, wherein one pin of an extended pair of pins is in electrical contact with said live plate and the other pin is in electrical contact with the neutral plate.
Claim 8
Dependent Claim
16 words
An electrical connector according to claim 4, wherein each of said plates has three apertures therein.
Claim 9
Dependent Claim
