Abstract

A method for manufacturing a contact piece and a metal part, capable of reliably making electrical contact and mechanical contact with other parts. The contact piece (31) connects the fixed piece (32) and the movable piece (33) which are substantially parallel with each other through a connecting portion (34). The lower surface of the front end of the movable piece (33) is provided with a movable contact portion (35) for contacting with a flexible printed circuit board, etc., and a movable contact portion (35) is provided on the rear end of the movable piece (33). The movable piece (33) is inclined to operate the receiving part (36). The front end portion of the fixing piece (32) is a fitting portion (37) for fitting with the housing of the connector. On the contact (31), a contact contact surface (35a) serving as a contact surface of the movable contact portion (35) is provided with concavo-convex shapes extending in the width direction of the contact (31). In addition, the lower surface of the fitting portion (37) is a contact surface with the crimping surface (37a), that is, the bottom surface of the housing, and the crimping surface (37a) is also provided with a of concave-convex shape.

Description

technical field [0001] The invention relates to a method of manufacturing a contact piece and a metal part. For example, it relates to a method of manufacturing a contact that is incorporated into a housing to form a connector and a metal member that can be used to manufacture the contact. Background technique [0002] Disclosed in Patent Document 1 as figure 1 (A) and figure 1 (B) Connector with the configuration shown. Two types of contacts (connection terminals) are assembled in the housing 12 of the connector 11 . figure 2 A contact piece 21 is indicated. The fixed piece 22 and the movable piece 23 of the contact piece 21 are substantially parallel, and the fixed piece 22 and the movable piece 23 are connected by a connecting portion 24 perpendicular to the two pieces 22 , 23 . A movable contact portion 25 is provided on the lower surface of the front end portion of the movable piece 23 , and the rear end portion of the movable piece 23 serves as an operation recei...
