Abstract
Abstract A connector of the hinging clamp type, with alignable bores to receive the end of a cable (e.g. conductor) which is securely clamped between the jaws when they are rotatably adjusted to closed position, is provided with mating locking rib and keeper notch in which the rib is received in the closed position, thus to lock the jaws in securely gripping engagement with the conductor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
243 words
A clamp type cable connector comprising: a male jaw including an attachment tail; a transversely extending cylindrical trunnion head projecting from said tail normal to its plane at one end thereof; a reduced neck joining said head to said tail; and a bore extending through said head with its axis in a medial longitudinal plane of said male jaw a female jaw including an attachment tail; a socket yoke comprising diametrically opposed arms joined by a bridging crown, one of said arms being integrally joined to an end of said female jaw tail and projecting normally therefrom to said crown, the other arm projecting from said crown toward the extended plane of said female jaw tail; said crown toward the extended plane of said female jaw tail; said arms cooperatively defining a cylindrical socket of more than 180* circumferential extent within which said head is received for limited relative hinging movements of said jaws between open and closed positions; said jaws having matable locking elements one of which is a transverse keeper notch in one of said jaws and another of which is a transverse, projecting rib receivable in said notch in the closed position of said jaws; and a cable-receiving bore extending diametrically through the arms of said yoke with its axis in said medial longitudinal plane of said male jaw; said bore of the yoke being alignable with said bore of the head in the said open position of the jaws.
Claim 2
Dependent Claim
243 words
A clamp type cable connector comprising: a male jaw including an attachment tail; a transversely extending cylindrical trunnion head projecting from said tail normal to its plane at one end thereof; a reduced neck joining said head to said tail; and a bore extending through said head with its axis in a medial longitudinal plane of said male jaw a female jaw including an attachment tail; a socket yoke comprising diametrically opposed arms joined by a bridging crown, one of said arms being integrally joined to an end of said female jaw tail and projecting normally therefrom to said crown, the other arm projecting from said crown toward the extended plane of said female jaw tail; said crown toward the extended plane of said female jaw tail; said arms cooperatively defining a cylindrical socket of more than 180* circumferential extent within which said head is received for limited relative hinging movements of said jaws between open and closed positions; said jaws having matable locking elements one of which is a transverse keeper notch in one of said jaws and another of which is a transverse, projecting rib receivable in said notch in the closed position of said jaws; and a cable-receiving bore extending diametrically through the arms of said yoke with its axis in said medial longitudinal plane of said male jaw; said bore of the yoke being alignable with said bore of the head in the said open position of the jaws.
Claim 3
Dependent Claim
26 words
An cable connector as defined in claim 1; said locking elements being located adjacent the respective junctions between said tails and said head and yoke respectively.
Claim 4
Dependent Claim
38 words
A cable connector as defined in claim 1; said one locking element being an inwardly turned transverse lip on the free end of said yoke; said other locking element being a transverse notch in said male jaw head.
Claim 5
Dependent Claim
52 words
A cable connector as defined in claim 1, said socket yoke having resiliency such as to provide for enforced spreading of said arms during movements of said jaws between open and closed positions, and such as to spring-load said locking elements into mating interengagement to lock said jaws in said closed position.
Claim 6
Dependent Claim
31 words
A cable connector as defined in claim 4; said keeper notch being located in the yoke of said female jaw; said rib being disposed on the head of said male jaw.
Claim 7
Dependent Claim
25 words
An cable connector as defined in claim 5; said keeper notch being in said one yoke arm adjacent its junction with said female jaw tail.
Claim 8
Dependent Claim
43 words
An cable connector as defined in claim 6; said junction having a latch projection defining one side of said keeper notch; said projection being engageable in a recess between said rib and said male jaw tail in said closed positions of the jaws.
Claim 9
Dependent Claim
30 words
An cable connector as definEd in claim 7; said projection resting on said rib in the open position of said jaws, whereby to support the jaws in said open position.
Claim 10
Dependent Claim
67 words
An cable connector as defined in claim 4; said other yoke arm terminating in a finger extending said yoke beyond an 180* circumferential extent thereof; said finger being receivable in a recess beneath said head at the end of said male jaw tail adjoining said neck and engageable against said neck in said open position of the jaws, whereby to limit the opening movement of said jaws.
Claim 11
Dependent Claim
48 words
An cable connector as defined in claim 9; said finger having a flat outer face and being tapered so that said outer face will lie substantially in the plane of the face of said tail which is mounted against a support, when said jaws are in open position.
