Insert for fitting socket contact-bushes into multi-pole connector e.g. for motor vehicle cable harness

摘要

A multi-pole electrical connector has a large number of contact bushes or pins arranged in parallel within a cylindrical housing. The identification of each one is made using a insert in the form of a light-source 10 that has a light emitting diode (LED) 13 within a sleeve12 which is inserted in the appropriate connector bush prior to fitment. Internally the unit has a spring loaded 36 piston 25 with a needle contact 28. A sleeve 20 fits in a carrier plate with the external contact pin extending beyond the surface.
