Abstract
A wire connector wherein the wire engaging core and electrically insulated housing are molded with an exterior surface of a molded wire engaging core used as a mold surface as the electrically insulated housing is molded around the wire engaging core to provide a wire connector with a molded housing and a molded wire engaging core.
Claims4
A method of making a twist-on wire connector comprising:
- forming a mold cavity in a first mold having an internal mold part with the internal mold part having a mold surface in the shape of a female spiral thread;
- injecting a liquid metal into the mold cavity to form an electrically conducting spiral core;
- removing the electrically conducting spiral core from the mold cavity by removing the internal mold part with the electrically conducting spiral core retained thereon;
- placing the electrically conducting spiral core retained on the internal mold part in a second mold cavity;
- injecting an electrically insulating polymer plastic into a second mold cavity to cover an exterior surface of the electrically conducting spiral core;
- removing the internal mold part from the second mold while retaining the electrically conducting spiral core on the internal mold part to provide an injection molded twist-on wire connector with an electrically conducting spiral core and an external insulated housing;
- wherein the liquid metal injected comprises a liquid metallic amorphous alloy.
