Abstract
A cam structure is pivotally moving between electronic parts to act on the other parts, which enables the action on the other parts upon pivotal movement to be varied by partly modifying a cam shape of the cam structure. For example, when the cam structure is pivotally moved in a connector to bring contacts into contact with a connecting object inserted in the connector, contact pressure of the contacts is controlled by partly modifying the cam shape of the cam structure. The cam structure has advantages that its cam portion can be pivotally moved by a slight force without requiring any large force and being capable of shifting the timing at which the cam contacts the mating parts depending upon customers specifications.
Claims5
A connector detachably fitting with a connecting object, including a required number of contacts each having a contact portion adapted to contact said connecting object, a housing holding and fixing said contacts therein and having a fining opening for inserting said connecting object thereinto, and a pivoting member having a cam portion which urges said contacts,
- wherein said contacts each have at one end said contact portion adapted to contact said connecting object and at the other end a pressure receiving portion adapted to be urged by said cam portion of said pivoting member, and
- wherein said pivoting member is pivotally mounted on said housing so as to urge the pressure receiving portions of said contacts upon pivotal movement of said pivoting member, wherein said cam of the pivoting member is shaped to have a plurality of elliptical cross-sections that are stepwisely shifted so that the contacts pressed by the cam are divided into plural groups to decrease the pivotal power.
