Abstract
Abstract The selective connection device has a safety disc and a complementary disc pivotally mounted on the socket coaxially with the safety disc and displaceable in rotational motion at the same time as the safety disc between the initial position and the final connection position. The complementary disc has a number of openings corresponding to the number of contact locations on the socket and distributed in the same manner. The relative angular position of the socket and of the complementary disc is such that the openings come opposite to the contact locations in the final position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
224 words
A selective electrical connection device comprising a housing arranged to support a centrally perforated insulating socket member having an end wall, said socket member having a plurality of means defining openings therein arranged in predetermined spaced relation around said central perforation and adapted to slidably support electrical contact means, plural juxtaposed disc members associated with said end wall of said socket member, resilient means encompassing said socket member and adapted to support a washer means, said washer means including means cooperating with said juxtaposed disc members to prevent inadvertent rotary movement thereof, plug means arranged for assembly with said insulating support member, said plug means having a collar element arranged to be interposed between the socket member and the housing upon electrical connection being established, a central ground contact element for cooperation with said perforation in said socket member and a further electrical contact element laterally spaced therefrom supported on said plug means arranged to be associated with at least one of said electrical contact means spaced around said central perforation in said socket member when said collar element is inserted into said housing to depress said resilient means thereby disengaging said washer from said juxtaposed disc members to permit relative rotation thereof and engagement of said electrical contact element with at least one of said electrical contact means carried by said socket member.
Claim 2
Dependent Claim
224 words
A selective electrical connection device comprising a housing arranged to support a centrally perforated insulating socket member having an end wall, said socket member having a plurality of means defining openings therein arranged in predetermined spaced relation around said central perforation and adapted to slidably support electrical contact means, plural juxtaposed disc members associated with said end wall of said socket member, resilient means encompassing said socket member and adapted to support a washer means, said washer means including means cooperating with said juxtaposed disc members to prevent inadvertent rotary movement thereof, plug means arranged for assembly with said insulating support member, said plug means having a collar element arranged to be interposed between the socket member and the housing upon electrical connection being established, a central ground contact element for cooperation with said perforation in said socket member and a further electrical contact element laterally spaced therefrom supported on said plug means arranged to be associated with at least one of said electrical contact means spaced around said central perforation in said socket member when said collar element is inserted into said housing to depress said resilient means thereby disengaging said washer from said juxtaposed disc members to permit relative rotation thereof and engagement of said electrical contact element with at least one of said electrical contact means carried by said socket member.
Claim 3
Dependent Claim
31 words
A selective electrical connection device as claimed in claim 1, in which the socket member has an exterior wall provided with means serving to assure rectilinear reciprocation of said washer means.
Claim 4
Dependent Claim
22 words
A selective electrical connection device as claimed in claim 1, in which each of said disc members are constructed of insulative material.
Claim 5
Dependent Claim
45 words
A selective electrical connection device as claimed in claim 1, in which the said disc member that engages the end wall of said socket member is provided with a plurality of peripheral grooves which are arranged to cooperate with said means on said washer means.
Claim 6
Dependent Claim
33 words
A selective electrical connection device as claimed in claim 4, wherein the said disc member engaging the end wall of said socket member is provided with at least four means defining openings therein.
Claim 7
Dependent Claim
61 words
A selective electrical connection device as claimed in claim 4, in which the said disc member supported by said disc member engaging said end wall of said socket member is provided with at least five openings therein, one of which forms a circular arc capable of accomodating said further electrical contact element carried by said plug means in five different positions.
