Abstract
An electrical terminal applicator with a molded frame composed of a polymer base material mixed with 10% to 25% total weight of a reinforcing material such as glass fiber or carbon fiber. Prior to injecting the mixture into a mold, steel inserts for attaching various components are installed in the mold. A feed mechanism feeds a terminal strip into a crimp region. A plunger with a crimp punch reciprocates vertically within a plunger channel in the frame. An anvil is mounted to the base plate and extends into the crimping region. The punch and anvil are shaped to crimp the terminal to the wire conductor.
Claims8
An electrical terminal applicator comprising:
- (a) a base plate;
- (b) a frame mounted to the base plate and having a plunger channel, the frame being composed of a hardened mixture of a polymer base material mixed with a reinforcing material selected from the group consisting of glass fibers, carbon fibers, and ceramic powders, the reinforcing material comprising between 10% and 25% of the total weight of the mixture;
- (c) a plunger mounted to reciprocate within the plunger channel, and adapted to be reciprocated by a press between a crimping position and a feeding position;
- (d) a feeder mechanism adapted to feed an electrical terminal into a crimping region when the plunger is in the feeding position;
- (e) an anvil extending from the base into the crimping region;
- (f) a crimp punch attached to the plunger and being positioned on the plunger such that, when the plunger is in the crimping position, the crimp punch crimps the electrical terminal in the crimping region between the crimp punch and the anvil and, when the plunger is in the feeding position, the crimp punch is separated from the anvil.
