Abstract
Abstract A crimping tool carries out both trimming and splicing operations in a single stroke so that the wires are trimmed between the ends of a connector; the wires do not sag and the trimmed wire ends lie within the connector. The tool has a pair of wire-trimming blades mounted for rotation on either side of the path of a movable die, which blades cooperate with trimming edges extending along such path. Each wire is oriented so as to be within the path of movement of one trimming blade and outside the path of movement of the other.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
Apparatus for trimming and splicing wires, the apparatus comprising a first connector-crimping die movable through a working stroke towards a second connector-crimping die to crimp an essentially U-section electrical connector disposed between the dies to a pair of wires within the connector, a pair of wiretrimming edges extending lengthwise of and beside the path of movement of the first die, and a wire-trimming blade associated with each wire-trimming edge and being rotatable relative to the edge to trim one of the wires in cooperation with the edge and between the ends of the connector, prior to the connector being engaged between the dies.
Claim 2
Dependent Claim
103 words
Apparatus for trimming and splicing wires, the apparatus comprising a first connector-crimping die movable through a working stroke towards a second connector-crimping die to crimp an essentially U-section electrical connector disposed between the dies to a pair of wires within the connector, a pair of wiretrimming edges extending lengthwise of and beside the path of movement of the first die, and a wire-trimming blade associated with each wire-trimming edge and being rotatable relative to the edge to trim one of the wires in cooperation with the edge and between the ends of the connector, prior to the connector being engaged between the dies.
Claim 3
Dependent Claim
46 words
Apparatus according to claim 1, which comprises a pair of wire-gripping members each positioned to support one of the wires so that its end portion intersects the path of movement of one of the blades but lies beyond the path of movement of the other blade.
Claim 4
Dependent Claim
44 words
Apparatus according to claim 2, in which each wire-gripping member has a wire-receiving slot extending transversely of the path of movement of the first die, the slots being of different depths and each being disposed beyond the path of movement of the adjacent blades.
Claim 5
Dependent Claim
63 words
Apparatus according to claim 1, in which the wire-trimming edges are provided on a wire-trimming block disposed between the blades, the blades being rotatable about a common axis, or about axes displaced from one another transversely of the path of movement of the first die, the blades being driven in rotation by projections on the first die, against the action of return springs.
Claim 6
Dependent Claim
56 words
Apparatus according to claim 1, in which the wire-trimming blades extend at right angles to the path of movement of the first die prior to its working stroke, said wire-trimming having wire-gathering projections extending in the direction of this path when the blades extend at right angles to the path of movement of the first die.
Claim 7
Dependent Claim
81 words
Apparatus according to Claim 1, in which the connector forms part of a strip of connectors arranged in end-to-end strip form, the connector being arranged to be sheared from the strip by a shear blade mounted adjacent the path of movement of the first die and against which the strip of connectors is arranged to be driven by the first die to shear the connector from the strip during the working stroke in cooperation with an edge of the first die.
Claim 8
Dependent Claim
124 words
Apparatus according to claim 6, in which the strip of connectors is arranged to be advanced to position the leading connector of the strip adjacent the first die by a feed finger which engages in a first hole in the strip of connectors prior to the working stroke of the first die, the strip being moved towards the second die by the first die during its working stroke to disengage the feed finger from the hole, the feed finger being retracted during the working stroke of the first die so as to engage in a second hole in the strip upstream of the first hole and being advanced when the return stroke of the first die has been completed, to advance the leading connector.
Claim 9
Dependent Claim
31 words
Apparatus according to claim 7, in which the advance of the leading connector is limited by a stop plate on the opposite side of the first die to the feed finger.
Claim 10
Dependent Claim
51 words
Apparatus according to claim 7, in which the feed finger is carried by an arm rotatably mounted on a frame of the apparatus, the arm being moved away from the first die by a projection thereon against the action of a return spring during the working stroke of the first die.
Claim 11
Dependent Claim
54 words
Apparatus according to claim 6 in which the strip of connectors is guided by a guide tube having a hole through the which the first die can pass with clearance, the guide tube having an open side to allow the strip of connectors to be moved towards the second die by the first die.
