Overmoulding can be used to facilitate the sterilization of electrical connectors.

A manufacturer of miniature high-reliability connectors, Omnetics Connector Corp. (Minneapolis, MN, USA), has invested in new equipment to triple its precision overmoulding production capability, citing a growing number of companies that are using the procedure to mould electrical connector housings. According to the firm, the approach facilitates sterilization, ensures that contamination is minimized, and results in savings in space, weight, and cost. The manufacturer has organized its factory so that it can offer overmoulding services for volumes ranging from short runs to large quantities.

During the procedure, connector insulators are assembled with prewired pins, sockets, or connectors that have solder lugs on the back. Assembly drawings or solid models are used to determine the internal dimensions of the housings, handles, and probes that will contain the connectors. Injection over­mould­­­ing is then used to form the final assembly. A range of materials, from soft silicones to hard nylon and polystyrenes, can be used in tool handles, and custom logos and col­ours can be incorporated using the procedure.
