Abstract
Abstract A hand tool for inserting wires into electrical terminals of an electrical connector has a wire insertion head defining a channel for the connector and a ram for driving wires successively into terminals of the connector. The connector is advanced in a step wise fashion through the channel after each wire has been inserted into a terminal. The ram has a depending pin engaging in a transverse slot in a cam plate carrying a spring loaded connector advancing pawl for engaging openings in the connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
A hand tool for successively connecting wires to respective electrical terminals arranged in a row extending along at least one side of a housing of an electrical connector, the tool comprising a wire insertion head, defining a connector channel, a wire insertion ram, means for driving the ram towards and away from the channel transversely of the length thereof, and means connected to the ram for advancing the connector step by step through the channel to bring each successive terminal into alignment with the ram to allow the ram to drive a wire into the terminal, wherein the connector advancing means comprises: a cam plate having a cam slot extending transversely of the path of movement of the ram, a camming pin fixed with respect to the ram and sliding in said cam slot, a connector advancing pawl mounted in a leading edge of said cam plate, and spring means biasing said pawl into engagement with the connector, whereby the cam plate is driven by the ram transversely of the path of movement thereof.
Claim 2
Dependent Claim
174 words
A hand tool for successively connecting wires to respective electrical terminals arranged in a row extending along at least one side of a housing of an electrical connector, the tool comprising a wire insertion head, defining a connector channel, a wire insertion ram, means for driving the ram towards and away from the channel transversely of the length thereof, and means connected to the ram for advancing the connector step by step through the channel to bring each successive terminal into alignment with the ram to allow the ram to drive a wire into the terminal, wherein the connector advancing means comprises: a cam plate having a cam slot extending transversely of the path of movement of the ram, a camming pin fixed with respect to the ram and sliding in said cam slot, a connector advancing pawl mounted in a leading edge of said cam plate, and spring means biasing said pawl into engagement with the connector, whereby the cam plate is driven by the ram transversely of the path of movement thereof.
Claim 3
Dependent Claim
28 words
A tool according to claim 1, wherein the cam plate is slidably mounted in a recess in the insertion head, the cam slot being remote from the pawl.
Claim 4
Dependent Claim
29 words
A tool according to claim 1, wherein the ram is received in a yoke member connected to a ram drive shaft, the camming pin extending from the yoke member.
Claim 5
Dependent Claim
34 words
A tool according to claim 3, wherein the ram is received in an axial channel in the yoke member, the camming pin being slidably received in an opening in the bore of the channel.
Claim 6
Dependent Claim
33 words
A tool according to claim 1, further comprising: a spring loaded ratchet stop projecting from a sidewall of the channel which is remote from the ram and in substantial alignment with the pawl.
