Abstract
Abstract A commoning element for electrically interconnecting a row of electrical contacts within a connector housing block is disclosed. A plurality of contact members are seated within a row of housing block cavities which are accessible from an upper surface of the housing block. The commoning element, comprising an elongate helical spring, is axially positioned across the row of cavities and subsequently compressed downwardly by a cover plate, whereupon commoning electrical engagement between coils of the helical spring and the contact members is established.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
In an electrical connector of the type comprising a housing block having a row of cavities within one surface thereof, contact members seated in respective ones of said row of cavities, and commoning means for electrically connecting each said contact member, the improvement comprising: each of said contact members comprising support portion means positioned within a respective cavity of said row of cavities, said cavities being open to said one surface; said commoning means comprising elongate radially compressible spring means positioned transversely above said support portion means of said contact members; and means provided by said housing block being movable towards said one surface for covering said row of cavities along said one surface, radially compressing said spring means through said one surface into intimate engagement against said support means of said contact members and to maintain said spring means in electrical contact with said contact members whereby electrical contact is established between said contact members.
Claim 2
Dependent Claim
156 words
In an electrical connector of the type comprising a housing block having a row of cavities within one surface thereof, contact members seated in respective ones of said row of cavities, and commoning means for electrically connecting each said contact member, the improvement comprising: each of said contact members comprising support portion means positioned within a respective cavity of said row of cavities, said cavities being open to said one surface; said commoning means comprising elongate radially compressible spring means positioned transversely above said support portion means of said contact members; and means provided by said housing block being movable towards said one surface for covering said row of cavities along said one surface, radially compressing said spring means through said one surface into intimate engagement against said support means of said contact members and to maintain said spring means in electrical contact with said contact members whereby electrical contact is established between said contact members.
Claim 3
Dependent Claim
33 words

Dependent Claim
148 words
In an electrical connector of the type comprising a housing block having a row of contact members seated within one surface thereof, and commoning means for electrically connecting each said contact member, the improvement comprising: each of said contact members comprising support portion means positioned within a cavity of said housing block which is open to said one surface; said commoning means comprising an elongate helical spring member located transversely above said support portion means of said contact members; cover plate means provided by said housing block and being movable towards said one surface for covering said support portion means along said one surface, radially compressing said helical spring member through said one surface into intimate engagement against said support portion means of said contact members to maintain said helical spring member in electrical contact with said contact members, whereby electrical contact is established between said contact members.
Claim 7
Dependent Claim
32 words
An electrical connector as set forth in claim 4, wherein said cover plate means includes rearwardly disposed means for providing strain relief to an electrical cable electrically connected to said contact members.
Claim 8
Dependent Claim
159 words
In an electrical connector of the type comprising a housing block having a row of cavities in one surface thereof, adjacent cavities being separated by integral barriers and each of said cavities receiving a contact member therein, and commoning means for electrically connecting each said contact member, the improvement comprising: each said contact member comprising support portion means positioned within a respective one of said cavities, said support portion means being openly accessible from said one surface; each of said cavity barriers having a top surface recessed slightly below said one surface, whereby a shallow channel is defined across said row of cavities; said commoning means comprising an elongate helical spring member located within said channel and having coils projecting into respective cavities toward said support portion means of said contact members; and means for radially compressing said helical spring member against said support portion means of said contact members, whereby electrical contact is established between said contact members.
