Abstract
Abstract A connector half (2) includes a housing (10) and a bolt fastener (50) having a neck (56) adapted to receive a plate fastener (70) inserted transversely to the bolt through a slot (20) in the connector housing to lock the bolt to the housing. Various embodiments of the plate fastener (70), (70'), and (70") are included, and in one embodiment, the bolt is made to include a neck (54) adapted to receive projections (38) interiorly of a bore (36) in the housing to hold the bolt in position prior to insertion of the fastener plate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
210 words
An electrical connector of a type having a bolt operable to draw and hold connector halves together to interconnect electrical circuits, said connector having a housing including a forward mating face and a rear face with arrays of cavities extending therebetween, a bore formed in said housing having a given diameter in a portion of said housing proximate said rear face and a lesser diameter extending from said rear face to the forward face, a bolt having a head of a diameter larger than the given diameter of said bore and a shank of a diameter smaller than the lesser diameter of said bore, said shank including a neck of a diameter less than that of said shank diameter located proximate said forward mating face in said housing, a slot in said housing essentially transecting said bore, said slot having an opening on the outside of said housing, plate fastener of a dimension to slidingly fit in said slot, said fastener having surfaces positioned and dimensioned to engage said neck of said shank upon insertion of said fastener through said opening of said slot in a direction normal to said and lock said bolt to said housing, and means to latch said fastener in said slot and to said housing.
Claim 2
Dependent Claim
210 words
An electrical connector of a type having a bolt operable to draw and hold connector halves together to interconnect electrical circuits, said connector having a housing including a forward mating face and a rear face with arrays of cavities extending therebetween, a bore formed in said housing having a given diameter in a portion of said housing proximate said rear face and a lesser diameter extending from said rear face to the forward face, a bolt having a head of a diameter larger than the given diameter of said bore and a shank of a diameter smaller than the lesser diameter of said bore, said shank including a neck of a diameter less than that of said shank diameter located proximate said forward mating face in said housing, a slot in said housing essentially transecting said bore, said slot having an opening on the outside of said housing, plate fastener of a dimension to slidingly fit in said slot, said fastener having surfaces positioned and dimensioned to engage said neck of said shank upon insertion of said fastener through said opening of said slot in a direction normal to said and lock said bolt to said housing, and means to latch said fastener in said slot and to said housing.
Claim 3
Dependent Claim
24 words
The connector of claim 1 wherein said surfaces are defined by a slot extending from one end of the fastener toward the center thereof.
Claim 4
Dependent Claim
51 words
The connector of claim 1 wherein said surfaces are defined by an aperture in said fastener having different width dimensions with respect to the said neck to facilitate insertion of the bolt through the fastener and displacement of the fastener transversely to effect said locking of the bolt to the connector.
Claim 5
Dependent Claim
22 words
The connector of claim 1 wherein said means is comprised of a bump in the fastener and a relief in the housing.
Claim 6
Dependent Claim
27 words
The connector of claim 1 wherein said fastener includes a turned up end and the housing includes a relief to receive said end entirely within said housing.
Claim 7
Dependent Claim
36 words
The connector of claim 1 wherein said shank includes a further reduced diameter portion and said housing includes means to engage said portion to latch said bolt in said housing prior to insertion of said fastener.
Claim 8
Dependent Claim
41 words
The connector of claim 6 wherein said reduced diameter of said shank is of a dimension to provide a shearing of said bolt at said portion in the presence of overstressing of said bolt to preclude stripping of said bolt threads.
Claim 9
Dependent Claim
19 words
The connector of claim 1 wherein said bolt is disposed in a bolt-retaining housing having lug means disposed thereon.
Claim 10
Dependent Claim
89 words
An electrical connector of a type having a bolt for drawing connector halves together to interconnect electrical circuits, comprising: a housing with a bore, a slot transverse to said bore, and a plurality of electrical contact-receiving cavities; a frangible bolt having an engaging portion disposed in said housing bore; fastening plate means disposed in said slot adjacent said bolt engaging portion operable from a first, engaging position to a second, disengaging position; whereby moving the fastening means to the disengaged position provides separation of the bolt from the housing.
Claim 11
Dependent Claim
89 words
An electrical connector of a type having a bolt for drawing connector halves together to interconnect electrical circuits, comprising: a housing with a bore, a slot transverse to said bore, and a plurality of electrical contact-receiving cavities; a frangible bolt having an engaging portion disposed in said housing bore; fastening plate means disposed in said slot adjacent said bolt engaging portion operable from a first, engaging position to a second, disengaging position; whereby moving the fastening means to the disengaged position provides separation of the bolt from the housing.
Claim 12
Dependent Claim
14 words
An electrical connector of claim 9, wherein said fastening plate means includes a slot.
Claim 13
Dependent Claim
14 words
An electrical connector of claim 9, wherein said fastening plate means includes an aperture.
