Automatic temporary connection of cables and wires - uses stackable plastic housing contg. EM latches, and has buffer to actuate auxiliary contact

摘要

The contact arrangement is for automatic temporary connection of cables and wires to a test device for electrical and electronic equipment. It can be operated rapidly using one hand and enables any number of contact positions to be served by choosing the number of elements used. The connection to a cable or wire takes place automatically. The wire is pushed past a contact housing (3) with a contact pin (4) until it presses against a plastic buffer (5). The buffer actuates an auxiliary contact via a spring (6). The auxiliary contact triggers a self-latching electrical circuit which connects the supply voltage to an electromagnet (10). The electromagnet pulls a soft iron lever (11) which presses the contact pin against the wire until the latching current is interrupted. The unit is in a stackable plastic housing (1).
