Method of crimping a terminal onto an electrical wire equipped with a water-proof plug using a positioning means

Abstract

An apparatus is provided that crimps an electrical wire having a water-proof plug onto a connector terminal in a given positional relationship and can be applied to an automatic assembling operation. In the vicinity of upper crimping members and lower crimping members of the apparatus which crimp an electrical wire having a water-proof plug onto the connector terminal, there are provided a water-proof plug positioning member which has a positioning protuberance used for placing a water-proof plug in a given position with respect to the front end of the connector terminal and a terminal positioning member which is vertically movable and engages with a positioning groove of the connector terminal. The front end face of a water-proof plus sealing section is brought into contact with the rear surface of a positioning protuberance, thereby placing the water-proof plug in a predetermined position. The upper surface of the positioning protuberance is formed into a concave circular-arch surface having the same radius as that of a water-proof plug cylindrical portion. The water-proof plug positioning member is provided so as to be able to vertically move while remaining in slidable contact with the rear surface of the lower crimping member.
