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the wire end in an electrically conductive manner with the PCB pin and for allowing the wire end to be inserted in or withdrawn from the housing.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.

Abstract: A first contact, made of a spring-like material, extends into a housing through the bottom end thereof and adjacent the right end of the housing such that a first portion of the first contact extends into the housing and a second portion extends out of the housing, the first portion being bent back upon itself within the housing. A second contact, also made of a spring-like material, also extends into the housing through the bottom end and adjacent a left end of the housing, once again, such that a first portion of the first contact extends into the housing and a second portion of the second contact extends out of the housing, the first portion of the second contact also being bent back upon itself within the housing. Thus, the two contacts are substantially in the form of an M disconnected at the tip of the apex thereof.
