Abstract
Abstract The present invention relates to a hand held and hand actuated tool for terminating wires into terminals housed in a connector. More particularly, the invention includes an indexing system which advances the connector through a notch either before or after a wire is terminated therein. The indexing system employes a wheel which drives the connector and an indexing lever, operating off of the wire stuffing ram, which drives the wheel.

Claim 1
Independent Claim
276 words
A hand tool for crimping wires into a connector of the type having a row of cavities on each side and with terminals of the type having wire-receiving slotted blades being positioned in the cavities, said tool comprising: a. a piston-shaped handle having a movable shaft and means for moving the shaft back and forth; b. wire stuffer means attached to the forward end of the shaft for stuffing wires into the wire-receiving slotted blades in the terminals; c. a work frame attached to the front end of the handle and having a transversely-extending, connector-receiving notch, a block positioned immediately behind the notch and having a longitudinally extending slot through which the wire stuffer means moves and also having wire guide means on the side facing the notch and which intersects the slot so that as the wire stuffer means moves forwardly through the slot it picks up a wire which may be in the guide means and moves it into the slotted blades in a terminal in a connector which may be in the notch, said frame further having an indexing wheel rotatably positioned in front of the notch, said wheel having means thereon adapted to engage a connector which may be in the notch; and d. indexing means connected to the wire stuffer means at one end and engageable with the indexing wheel at the other end so that as the wire stuffer means moves, it moves the indexing means which engages and rotates the indexing wheel which in turn engages and advances a connector which may be in the notch so as to position a terminal in front of the longitudinally extending slot.

A hand tool for crimping wires into a connector of the type having a row of cavities on each side and with terminals of the type having wire-receiving slotted blades being positioned in the cavities, said tool comprising: a. a piston-shaped handle having a movable shaft and means for moving the shaft back and forth; b. wire stuffer means attached to the forward end of the shaft for stuffing wires into the wire-receiving slotted blades in the terminals; c. a work frame attached to the front end of the handle and having a transversely-extending, connector-receiving notch, a block positioned immediately behind the notch and having a longitudinally extending slot through which the wire stuffer means moves and also having wire guide means on the side facing the notch and which intersects the slot so that as the wire stuffer means moves forwardly through the slot it picks up a wire which may be in the guide means and moves it into the slotted blades in a terminal in a connector which may be in the notch, said frame further having an indexing wheel rotatably positioned in front of the notch, said wheel having means thereon adapted to engage a connector which may be in the notch; and d. indexing means connected to the wire stuffer means at one end and engageable with the indexing wheel at the other end so that as the wire stuffer means moves, it moves the indexing means which engages and rotates the indexing wheel which in turn engages and advances a connector which may be in the notch so as to position a terminal in front of the longitudinally extending slot.
Claim 3
Dependent Claim
24 words
The hand tool of claim 1 further including spring-biased detent means located on the work frame for retaining the indexing wheel against inadvertent movement.
Claim 4
Dependent Claim
36 words
The hand tool of claim 2 further including a shaft and knob attached to the indexing wheel for the purpose of moving the connector via the indexing wheel through the notch independent of the indexing means.
Claim 5
Dependent Claim
37 words
The hand tool of claim 3 wherein the indexing means includes a U-shaped member with the rear upright arm being attached to the wire stuffer means and the front upright arm being engageable with the indexing wheel.
Claim 6
Dependent Claim
61 words
The hand tool of claim 4 wherein the lower surface of the bight of the U-shaped member comprises a forward and rearward section with one section being displaced vertically upwardly with respect to the other section and the two sections being connected by a sloping section and further with the rear upright arm being pivotally connected to the wire stuffer means.
Claim 7
Dependent Claim
57 words
The hand tool of claim 5 further including a pin secured to the work frame and on which the lower surface of the U-shaped member rides so that as the member moves back and forth on the pin, the front upright arm moves up and down and thusly in and out of engagement with the indexing wheel.
