Abstract
Abstract A crimping head for use in tools for crimping removable crimp style electrical socket contacts is disclosed. The head includes a tail crimper affixed to a frame for shaping the contact's tail section into a probe hook. A tail anvil, slidably mounted on the frame and engagable against the tail crimper, compresses the tail section against the tail crimper to form the probe hook. Upper and lower crimping jaws, attached to the tail crimper and tail anvil, respectively, crimp the contact onto the end of a wire as the tail section is simultaneously formed into the probe hook.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
192 words
A crimping tool head for use in a tool for crimping electrical socket contacts of the type characterized as including a tail section, said head adapted for crimping one of said contacts onto the end of a prestripped insulated wire conductor and simultaneously forming a probe hook from the tail section of said contact, said head comprising: a frame; tail crimping means, coupled to said frame, for guiding the formation of said probe hook; upper crimping means, coupled to said tail crimping means, for guiding the formation of the section of said contact which is to be crimped on said wire conductor; tail anvil means, slidably coupled to said frame opposing said tail crimping means and engagable against the opposed surface of said tail crimping means, for compressing said tail section against said tail crimping means whereby said tail section is formed into said probe hook; and lower crimping means, slidably coupled to said frame opposing said upper crimping means and engagable with the opposed surface of said upper crimping means, for compressing the section of said contact which is to be crimped on said wire conductor against said upper crimping means.
Claim 2
Dependent Claim
192 words
A crimping tool head for use in a tool for crimping electrical socket contacts of the type characterized as including a tail section, said head adapted for crimping one of said contacts onto the end of a prestripped insulated wire conductor and simultaneously forming a probe hook from the tail section of said contact, said head comprising: a frame; tail crimping means, coupled to said frame, for guiding the formation of said probe hook; upper crimping means, coupled to said tail crimping means, for guiding the formation of the section of said contact which is to be crimped on said wire conductor; tail anvil means, slidably coupled to said frame opposing said tail crimping means and engagable against the opposed surface of said tail crimping means, for compressing said tail section against said tail crimping means whereby said tail section is formed into said probe hook; and lower crimping means, slidably coupled to said frame opposing said upper crimping means and engagable with the opposed surface of said upper crimping means, for compressing the section of said contact which is to be crimped on said wire conductor against said upper crimping means.
Claim 3
Dependent Claim
49 words
The crimping tool head as defined in claim 1 further characterized in that said tail anvil means is connected to said lower crimping means, whereby as said tail anvil means is engaged against said tail crimping means, said lower crimping means is simultaneously engaged with said upper crimping means.
Claim 4
Dependent Claim
44 words
The crimping tool head in accordance with claim 2 wherein the surface of said tail anvil means opposing the surface of said tail crimper means is characterized as having a rectangular shaped cavity, the base of said cavity including an inclined planar shaped projection.
Claim 5
Dependent Claim
49 words
The crimping tool head in accordance with claim 3 wherein the surface of said tail crimper means opposing the surface of said tail anvil means is characterized as having a projecting rectangular shaped member, said member matable with the cavity in the opposed surface of said tail anvil means.
Claim 6
Dependent Claim
34 words
The crimping tool head in accordance with claim 4 wherein the surface of said projecting rectangular shaped member is characterized as having a notch to accommodate said inclined planar shaped projection and said wire.
Claim 7
Dependent Claim
43 words
The crimping tool head as defined in claim 2 further characterized in that: said frame is essentially of an inverted U-shape; and said tail anvil means and said lower crimping means are in contact with and slidable along the legs of said frame.
Claim 8
Dependent Claim
38 words
The crimping tool head as defined in claim 6 further characterized in that said tail crimping means is mounted on the cross-member of said frame with its guiding surface opposing the compressing surface of said tail anvil means.
Claim 9
Dependent Claim
63 words
The crimping tool head as defined in claims 1 or 6 further including terminal holder means, coupled to said tail anvil means, for positioning the section of said contact to be crimped between the opposing surfaces of said upper and lower crimping means and for positioning the tail section between the opposing surfaces of said tail crimping means and said tail anvil means.
Claim 10
Dependent Claim
78 words
The crimping tool head in accordance with claim 8 wherein said terminal holder means further includes means for moving said terminal holder means between an engaged position and a disengaged position, said terminal holder in abutting contact with said lower crimping means when in the engaged position and remote from said lower crimping means when in the disengaged position, wherein said contact is properly positioned to be crimped when said terminal holder means is in the disengaged position.
Claim 11
Dependent Claim
75 words
The crimping tool head in accordance with claim 8 wherein said upper crimping means includes: insulation support crimper means for guiding the formation of the section of said contact which is to be crimped onto the insulated portion of said wire; and wire barrel crimper means, coupled to said insulation support crimper means, for guiding the formation of the section of said contact which is to be crimped onto the stripped portion of said wire.
Claim 12
Dependent Claim
67 words
The crimping tool head in accordance with claim 10 wherein said upper crimping means further includes hold down means, positioned between said insulation support crimper means and said wire barrel crimper means and slidably seated in a track in said insulation support crimper means, for maintaining said contact in position against said lower crimping means as said lower crimping means is engaged with said upper crimping means.
Claim 13
Dependent Claim
44 words
The crimping tool head in accordance with claim 10 wherein the surface of said tail anvil means opposing the surface of said tail crimper means is characterized as having a rectangular shaped cavity, the base of said cavity including an inclined planar shaped projection.
Claim 14
Dependent Claim
48 words
The crimping tool head in accordance with claim 12 wherein the surface of said tail crimper means opposing the surface of said tail anvil means is characterized as having a rectangular shaped member, said member matable with the cavity in the opposed surface of said tail anvil means.
Claim 15
Dependent Claim
34 words
The crimping tool head in accordance with claim 13 wherein the surface of said projecting rectangular shaped member is characterized as having a notch to accommodate said inclined planar shaped projection and said wire.
