Electrical connector components, for example, a pin terminal constructed from a solid wire pin and a formed metal body, are attached to a web carrier and fed through an inductive heating station, thereby bonding the components together. The components are pre-treated with a conductive bonding material which can be cured, flowed, or set by applying heat. The web carrier may be wound on a first spool, fed through the inductive heating station, and wound onto a second spool, for ready feed to and from successive production steps. The temperature of the heating operation may be controlled by varying the speed of the web feed and the strength of the inductive field, so as to ensure repeatable, uniform heating, at a high economical speed. In addition, the tip of the pin can be cooled during the heating operation, to prevent heat damage or contamination of the pin.

Method of inductively soldering electrical connector elements

Method and apparatus for inductively soldering electrical connector

A two-part multiterminal connector includes a terminal plug connector element and a complementary terminal socket connector element. A cam mounted on a shaft on one connector element includes a spiral camming channel which is centered on the shaft. The channel engages a cam follower mounted on the other connector element, whereby rotation of the cam about the shaft causes the cam follower to be drawn along the spiral camming channel. As the cam rotates, the cam follower is drawn closer to the shaft, causing the pin and socket terminals within the connector elements to mate. Reversal of the cam assembly disassembles the connector.
