Abstract
Abstract A connector for a multi-conductor circuit is disclosed which includes a base having a longitudinal cavity defining a plurality of seats whose spacing is equal to the distance between the centers of the conductors of a multi-conductor circuit. Pairs of springs, one pair for each seat, are connected to prongs emerging from the base, at least one spring of each pair being resiliently displaceable toward the other spring. A cover insertable into the cavity of the base includes a central longitudinal slot bounded by two resilient ledges through which a multi-conductor circuit is introduced. The ledges of the cover approach each other on insertion of the cover into the base and clamp the sheath of the multi-conductor circuit, at least one of the ledges having an extension for displacing one spring of each pair toward the opposing spring.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
154 words
A quick connector for a multi-conductor circuit comprising a base member having a longitudinal cavity divided into a plurality of seats whose center distances equal the center distances of conductors in a multi-conductor circuit, a pair of opposing springs for each seat connected to a common terminal emerging from the base member, at least one spring of each pair being yieldingly displaceable toward the other spring, and a cover insertable into the longitudinal cavity of the base member and having opposing resilient ledges defining a longitudinal slot through which a multi-conductor circuit may be introduced into the connector without force, said resilient ledges approaching each other during insertion of the cover into the cavity of the base member and retaining the multi-conductor circuit by clamping action, and means on at least one of said ledges engaging one corresponding spring of each pair and causing it to yieldingly approach the other spring of each pair.
Claim 2
Dependent Claim
154 words
A quick connector for a multi-conductor circuit comprising a base member having a longitudinal cavity divided into a plurality of seats whose center distances equal the center distances of conductors in a multi-conductor circuit, a pair of opposing springs for each seat connected to a common terminal emerging from the base member, at least one spring of each pair being yieldingly displaceable toward the other spring, and a cover insertable into the longitudinal cavity of the base member and having opposing resilient ledges defining a longitudinal slot through which a multi-conductor circuit may be introduced into the connector without force, said resilient ledges approaching each other during insertion of the cover into the cavity of the base member and retaining the multi-conductor circuit by clamping action, and means on at least one of said ledges engaging one corresponding spring of each pair and causing it to yieldingly approach the other spring of each pair.
Claim 3
Dependent Claim
95 words
A quick connector for a multi-conductor circuit as defined in claim 1, and said plurality of seats of the longitudinal cavity being separated by baffles whose top edges are inclined from the side walls of the cavity toward its center, said ledges being correspondingly inclined to a slightly greater degree than the tops of the baffles, whereby the ledges of the cover are bent upwardly when the cover is inserted into the cavity of the base member thereby causing the opposing edges of the ledges to exert a clamping force on the inserted multi-conductor circuit.
Claim 4
Dependent Claim
33 words
A quick connector for a multi-conductor circuit as defined in claim 1, and one spring of each opposing pair in each seat being spaced from the adjacent side wall surface of the seat.
Claim 5
Dependent Claim
30 words
A quick connector for a multi-conductor circuit as defined in claim 3, and the other spring of each opposing pair in each seat resting against a shoulder of said seat.
Claim 6
Dependent Claim
41 words
A quick connector for a multi-conductor circuit as defined in claim 1, and said cover being formed separately from the base member and comprising a frame from the side walls of which said ledges project toward each other in opposing relationship.
Claim 7
Dependent Claim
25 words
A quick connector for a multi-conductor circuit as defined in claim 1, and said base member and cover being elongated and of approximate parallelepiped form.
Claim 8
Dependent Claim
77 words
A quick connector for a multi-conductor circuit as defined in claim 3, and the longitudinal side wall of the cover adjacent to the springs which are spaced from the corresponding wall of the cavity having a tapered extension which during insertion of the cover into the cavity of the base member enters the space between such springs and the adjacent wall of the cavity and forces the springs yieldingly toward the corresponding opposing springs of the pairs.
Claim 9
Dependent Claim
50 words
A quick connector for a multi-conductor circuit as defined in claim 7, and the longitudinal side wall of the cover opposite to the side wall having the tapered extension entering a guide slot formed in the base member when the cover is introduced into the cavity of the base member.
Claim 10
Dependent Claim
42 words
A quick connector for a multi-conductor circuit as defined in claim 5, and said cover having on its opposite ends yielding connection elements which are snap-engageable with the base member as the cover is inserted into the cavity of the base member.
Claim 11
Dependent Claim
38 words
A quick connector for a multi-conductor circuit as defined in claim 9, and each connection element and the corresponding end wall of the base member being provided respectively with a slot and retention lug which are mutually engageable.
Claim 12
Dependent Claim
63 words
A quick connector for a multi-conductor circuit as defined in claim 10, and each connection element of the cover being provided with at least one yielding strip enabling the cover to be partially separated from the base member to a sufficient extent to permit separation of the multi-conductor circuit from the connector but preventing total separation of the cover from the base member.
Claim 13
Dependent Claim
46 words
A quick connector for a multi-conductor circuit as defined in claim 10, and each connection element of the cover and each retention lug of the base member being provided with cooperative inclined faces which hold the cover in a state of disengagement from the base member.
Claim 14
Dependent Claim
67 words
A quick connector for a multi-conductor circuit as defined in claim 1, and each seat being bounded by the longitudinal side walls of the base member and by a pair of baffles extending transversely to said longitudinal side walls, the opposing end faces of the baffles being separated on the longitudinal center line of the base member to allow introduction of the multi-conductor circuit into the connector.
Claim 15
Dependent Claim
38 words
A quick connector for a multi-conductor circuit as defined in claim 1, and each seat being bounded by the two longitudinal side walls of the base member and by continuous transverse walls which connect the longitudinal walls together.
Claim 16
Dependent Claim
43 words
A quick connector for a multi-conductor circuit as defined in claim 14, and the opposing surfaces of said ledges at positions registering with said seats having substantially semi-circular recesses which are substantially complementary to the sheaths of individual conductors of a multi-core cable.
Claim 17
Dependent Claim
35 words
A quick connector for a multi-conductor circuit as defined in claim 15, and said springs having substantially semi-circular cavities in their opposing faces which are substantially complementary to the individual conductors of a multi-core cable.
