Method of manufacturing self-locking wire terminal
View Patent ↗A self-locking wire terminal assembly and a shape memory wire termination system includes an electrical terminal constructed with spring legs which provide two opposing points of contact on a mating electrical conductive pin. The points of contact prevent the pin from being removed. The shape memory termination system is formed by electrically coupling a clip assembly to shape memory wire and to an electrical source. In one embodiment, the shape memory wire causes an actuator to activate when the shape memory wire dissipates electrical power. The terminal assemblies may be manufactured by assembling wire with conduction pads onto a continuous reel. The terminal assemblies may be formed from the reel by trimming wire and linkages between the conduction pads.
1. A method for manufacturing a wire terminal assembly comprising the steps of:
providing a plurality of conduction pads on at least one carrier strip, wherein adjacent conduction pads are connected by a connecting linkage, each of the conduction pads including a crimping portion;
inserting a continuous wire through the crimping portion of the plurality of conduction pads;
crimping the crimping portion of the plurality of conduction pads to secure the continuous wire to the crimping portion of each conduction pad to provide electrical conductivity between the continuous wire and each said conduction pad;
removing the at least one carrier strip; and
winding the plurality of conduction pads and the continuous wire onto a reel.
2. The method of claim 1 , further comprising the step of:
unwinding the reel to expose a first pair of adjacent conduction pads and a second pair of adjacent conduction pads.
3. The method of claim 2 , further comprising the step of removing the connecting linkage between the first pair of adjacent conduction pads and between the second pair of adjacent conduction pads to form a single wire terminal assembly.
4. The method of claim 1 , wherein the continuous wire is shape memory wire.
5. A method for manufacturing a wire terminal assembly comprising the steps of:
providing a plurality of conduction pads on at least one carrier strip, wherein adjacent conduction pads are connected by a connecting linkage, each of the conduction pads including a crimping portion;
inserting a continuous wire through the crimping portion of the plurality of conduction pads;
securing the continuous wire to the crimping portion of each conduction pad to provide electrical conductivity between the continuous wire and each said conduction pad;
removing the at least one carrier strip; and
winding the plurality of conduction pads and the continuous wire onto a reel,
wherein the plurality of conduction pads are self-locking conduction pads.
6. The method of claim 5 , wherein each of the self-locking conduction pads define an opening extending through the conduction pad and have a first spring leg defining a first contact surface and a second spring leg defining a second contact surface, the first and second contact surfaces being positioned in opposing relationship around the opening.
