Abstract
Abstract In a solderless electrical connector of the type having relatively rotatable jaws with alignable bores therein adapted to receive the bared end of a conductor which is securely clamped between the jaws when they are rotated to a closed position, there is disclosed an improvement wherein one of the jaws is provided with a locking rib and the other of the jaws is provided with a plurality of mating notches or grooves which receive the rib in different positions of the jaws thereby providing a ratchet mechanism to lock the jaws in securely gripping engagement with the conductor at multiple intermediate positions between the open and closed positions thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
205 words
In a solderless electrical connector of the rotatable jaw, clamping type comprising male and female jaws having respective mounting tails, said male jaw including a transverse cylindrical head joined to one end of said male jaw tail and having a bore which extends diametrically through the center of said head for receipt of conductor, said female jaw including a C-shaped yoke joined to one end of said female jaw tail and defining a transverse cylindrical socket which receives said head of said male jaw for relative angular movement of said jaws between an open, conductor-receiving position and a closed, conductor-clamping position, said yoke having cylindrical bores on a common diameter of said yoke which are alignable with said bore in said male jaw in said open position of said jaws, the improvement wherein one of said jaws includes a transverse locking rib and the other of said jaws includes a plurality of matIng transverse notches positioned so that different ones of said notches receive said locking rib in different relative positions of said jaws between said open and closed positions and wherein the notch engaged by said rib when said jaws are in said closed position is slightly larger than the remainder of said notches.
Claim 2
Dependent Claim
205 words
In a solderless electrical connector of the rotatable jaw, clamping type comprising male and female jaws having respective mounting tails, said male jaw including a transverse cylindrical head joined to one end of said male jaw tail and having a bore which extends diametrically through the center of said head for receipt of conductor, said female jaw including a C-shaped yoke joined to one end of said female jaw tail and defining a transverse cylindrical socket which receives said head of said male jaw for relative angular movement of said jaws between an open, conductor-receiving position and a closed, conductor-clamping position, said yoke having cylindrical bores on a common diameter of said yoke which are alignable with said bore in said male jaw in said open position of said jaws, the improvement wherein one of said jaws includes a transverse locking rib and the other of said jaws includes a plurality of matIng transverse notches positioned so that different ones of said notches receive said locking rib in different relative positions of said jaws between said open and closed positions and wherein the notch engaged by said rib when said jaws are in said closed position is slightly larger than the remainder of said notches.
Claim 3
Dependent Claim
205 words
In a solderless electrical connector of the rotatable jaw, clamping type comprising male and female jaws having respective mounting tails, said male jaw including a transverse cylindrical head joined to one end of said male jaw tail and having a bore which extends diametrically through the center of said head for receipt of conductor, said female jaw including a C-shaped yoke joined to one end of said female jaw tail and defining a transverse cylindrical socket which receives said head of said male jaw for relative angular movement of said jaws between an open, conductor-receiving position and a closed, conductorclamping position, said yoke having cylindrical bores on a common diameter of said yoke which are alignable with said bore in said male jaw in said open position of said jaws, the improvement wherein one of said jaws includes a transverse locking rib and the other of said jaws includes a plurality of matIng transverse notches positioned so that different ones of said notches receive said locking rib in different relative positions of said jaws between said open and closed positions and wherein the notch engaged by said rib when said jaws are in said closed position is slightly larger than the remainder of said notches.
Claim 4
Dependent Claim
205 words
In a solderless electrical connector of the rotatable jaw, clamping type comprising male and female jaws having respective mounting tails, said male jaw including a transverse cylindrical head joined to one end of said male jaw tail and having a bore which extends diametrically through the center of said head for receipt of conductor, said female jaw including a C-shaped yoke joined to one end of said female jaw tail and defining a transverse cylindrical socket which receives said head of said male jaw for relative angular movement of said jaws between an open, conductor-receiving position and a closed, conductorclamping position, said yoke having cylindrical bores on a common diameter of said yoke which are alignable with said bore in said male jaw in said open position of said jaws, the improvement wherein one of said jaws includes a transverse locking rib and the other of said jaws includes a plurality of matIng transverse notches positioned so that different ones of said notches receive said locking rib in different relative positions of said jaws between said open and closed positions and wherein the notch engaged by said rib when said jaws are in said closed position is slightly larger than the remainder of said notches.
Claim 5
Dependent Claim
53 words
In a solderless electrical connector according to claim 1, the improvement wherein said yoke of said female jaw is sufficiently resilient to permit spreading of the opposite sides thereof during movement of said jaws between said open and closed positions so as to spring-load said locking rib and said notches in mating engagement.
Claim 6
Dependent Claim
60 words
In a solderless electrical connector according to claim 1, the improvement wherein said locking rib does not engage any of said notches in the open position of said jaws and engages the first of said notches as said jaws are angularly rotated toward said closed position, said locking rib engaging each of said notches during rotation to said closed position.
Claim 7
Dependent Claim
44 words
In a solderless electrical connector according to claim 1, the improvement wherein sald locking rib engages said inner surface of said yoke immediately below said notches, when said jaws are in said open position, so as to maintain said jaws in said open position.
Claim 8
Dependent Claim
36 words
In a solderless electrical connector according to claim 1, the improvement wherein said lockking rib is positioned on said head of said male jaw and said notches are positioned in said yoke of said female jaw.
Claim 9
Dependent Claim
36 words
In a solderless electrical connector according to claim 5, the improvement wherein said locking rib is positioned at the back of said head of said male jaw, above the intersection between said head and said tail.
Claim 10
Dependent Claim
34 words
In a solderless electrical connector according to claim 6, the improvement wherein said locking rib is positioned approximately within a horizontal plane passing through the cylindrical axis of said head of said male jaw.
