Title: Screwless terminal block

Abstract: A screwless-type terminal block comprising a housing, a clamping member in the housing, a PCB conductive pin, and an actuating member. The housing defines a first opening for receiving therein a wire end and a second opening through which extends the actuating member which has a operating knob outside of the housing and a cammed end adapted to displace the clamping member between locked and unlocked positions thereof respectively for securing the wire end in an electrically conductive manner with the PCB pin and for allowing the wire end to be inserted in or withdrawn from the housing. When rotated, the operating knob causes the cammed end to rotate about a longitudinal axis of the actuating member such that the cammed end causes the clamping member to selectively displace between the locked and unlocked positions. The cammed end includes a flat surface angled with respect to the longitudinal axis and contacting the clamping member which displaces along a plane parallel to this longitudinal axis. The clamping is sprang loaded such as to be biased towards the PCB pin. The operating knob and the housing are provided with visible indicators to indicate if the clamping member is in its locked or unlocked position. The terminal block is nestable in a side-by-side relationship with other similar terminal blocks.
