Abstract
Abstract An electrical connection between high current contact members (26 and 27) is provided by a male and female securing member (10 and 11) of the same coefficient of expansion. The inner surface (21) of a tubular shaft component (19) of the female member (11) and the outer surface (22) of a tubular shaft (18) component of the male member (10) are provided with complementary tapers enabling mating together as a force fit so that plate portions (13 and 12) extending from the root ends of shaft components of respective members (11 and 10) clamp the securing members (26 and 27) therebetween. In one example, the securing members (41, 41') are identical and hermaphroditic, each shaft component (42 and 42') being of hemicylindrical shape and semicircular cross section, female sockets being defined by apertures (44 or 44') in plates (45 or 45').

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
189 words
An electrical connection comprising: first and second securing members, each of said members being integrally formed in one piece and of material having essentially matched thermal coefficients of expansion, each member including an annular plate portion having a shaft component extending axially outwardly from one face thereof; a socket portion defined by said first securing member, said socket portion having an aperture extending axially therethrough for receiving the shaft component of said second securing member, said second member shaft component being matable as a force fit in said socket portion; contact members having shaft-receiving apertures extending therethrough, the shaft component of said first securing member being inserted into said shaft-receiving apertures from one side of said contact members and the shaft component of said second securing member being inserted into said shaft-receiving apertures from the other side of said contact members, said shaft component of said second member being received and mated in said socket portion of said first member, thereby positioning said contact members between respective plate portions of said first and second securing members, and clamping said contact members together and establishing a permanent electrical connection therebetween.
Claim 2
Dependent Claim
189 words
An electrical connection comprising: first and second securing members, each of said members being integrally formed in one piece and of material having essentially matched thermal coefficients of expansion, each member including an annular plate portion having a shaft component extending axially outwardly from one face thereof; a socket portion defined by said first securing member, said socket portion having an aperture extending axially therethrough for receiving the shaft component of said second securing member, said second member shaft component being matable as a force fit in said socket portion; contact members having shaft-receiving apertures extending therethrough, the shaft component of said first securing member being inserted into said shaft-receiving apertures from one side of said contact members and the shaft component of said second securing member being inserted into said shaft-receiving apertures from the other side of said contact members, said shaft component of said second member being received and mated in said socket portion of said first member, thereby positioning said contact members between respective plate portions of said first and second securing members, and clamping said contact members together and establishing a permanent electrical connection therebetween.
Claim 3
Dependent Claim
60 words
The electrical connection as described in claim 1 wherein the exterior surface of the second member shaft component is tapered and the surface of said aperture in said socket portion of said first securing member is provided with a complimentary taper that engages the tapered surface of the tapered shaft component as the first and second securing members are mated.
Claim 4
Dependent Claim
37 words
The electrical connection as described in claim 2 wherein the outer surface of the shaft of said first securing member is provided with a taper that engages the peripheries of the shaft-receiving apertures of said contact members.
Claim 5
Dependent Claim
50 words
The electrical connection as described in claim 1 wherein said annular plate portions of said first and second securing members are provided with apertures for receiving fastening means therethrough, and said shaft components include cooperating passageways through which fastening means can extend to fasten said connection to a mounting member.
Claim 6
Dependent Claim
56 words
The electrical connection as described in claim 1 further comprising an other socket portion defined by said second securing member, said other socket portion having an aperture extending axially therethrough for receiving the shaft component of said first securing member, said first member shaft component being matable as a force fit in said other socket portion.
Claim 7
Dependent Claim
95 words
The electrical connection as described in claim 5 wherein said apertures in said socket and said other socket portions are formed in respective plate portions of said first and second securing members and each of said shaft components of said first and second securing members comprises a segment having a semicircular cross section, a free end portion of respective shaft components being received in the corresponding plate apertures of the other member, and a second opposite end of each of said shaft components forming a segment of the periphery of each of said plate apertures.
Claim 8
Dependent Claim
19 words
The electrical connection as described in claim 6 wherein said first and second securing members are identical and hermaphroditic.
Claim 9
Dependent Claim
191 words
An electrical fastener assembly comprising: first and second securing members, each of said members being integrally formed in one piece and of material having essentially matched thermal coefficients of expansion, each member including an annular plate portion having a shaft component extending axially outwardly from one face thereof; a socket portion defined by said first securing member, said socket portion having an aperture extending axially therethrough for receiving the shaft component of said second securing member, said second member shaft component being matable as a force fit in said socket portion; contact members having shaft-receiving apertures extending therethrough, the shaft component of said first securing member being inserted into said shaft-receiving apertures from one side of said contact members and the shaft component of said second securing member being inserted into said shaft-receiving apertures from the other side of said contact members, said shaft component of said second member being received and mated in said socket portion of said first member, thereby positioning said contact members between respective annular plate portions of said first and second securing members, and clamping said contact members together and establishing a permanent electrical connection therebetween.
