Title: Machine for clinching a multiple lead component

Abstract: A clinching machine for clinching the leads of a connector on a circuit board includes a top wall which provides a work surface having an opening for receiving the leads and a clamp for clamping the circuit board and the connector in place against the work surface. A pair of clinching jaws, each having a pair of work faces intersecting at an angle of less than 90.degree., are pivotably mounted in fixed relationship adjacent to the opening. Pneumatic actuators first cause the clamp to engage the circuit board and the connector, and then cause the jaws to pivot, thereby drawing the leads into close contact with land areas on the circuit board. The amount of rotation of the jaws corresponds to the difference between the intersecting angle and 90.degree..
