Abstract
Abstract A carrier system for facilitating the production of electrical assemblies with electrical components including a component carrier and a fixture for facilitating component insertion and removal with the carrier. The carrier comprises an open rectangular peripheral skirt with a transverse support plate for engaging a component housing. Spaced flexible bowed retaining arms extend across the peripheral skirt. Each arm has a clip extension for securing the component housing in the carrier. Central operating structures on each retaining arm facilitate movement between first and second positions. Slide tabs on each arm coact with the peripheral skirt to prevent rotation of the retaining arms during motion. Operating tabs are spaced at fixed positions relative to the peripheral skirt. Supporting plates interconnect each tab to a respective operating arm that is positioned within the peripheral skirt as a function of component housing size. The system also includes a fixture that deflects the operating tabs as a carrier moves through the fixture.
