A first cable conductor portion is placed on a first connector terminal. The first cable conductor portion is accommodated in a pressing recessed portion formed in an applying member. Ultrasonic vibration is applied to the first cable conductor portion and the first connector terminal and the first cable conductor portion and the first connector terminal are pressed, and thereby to be welded to each other.

Method of manufacturing connector for flat cable

A connector for a flat cable is equipped with a resin-made holder and a resin-made cover that is mounted on the holder. The holder has two metallic bus bars for making connection of a flat cable with two electric wires. The respective bus bars are insert molded in the holder and have flat plate-like portions of connection that are arranged in the form of a flat plane by being spaced away from each other. The outer periphery of each portion of connection is exposed from the holder. The flat cable has two conductors. The respective conductors have exposed conductor portions that are extended in array. Each electric wire has a core wire portion. On the respective connection portions there are superposed their corresponding exposed conductor portions and core wire portions, respectively. The respective core wire portions are connected to their corresponding connection portions by ultrasonic welding. A horn for use in ultrasonic welding presses each core wire portion toward its corresponding bus bar and simultaneously generates ultrasonic waves. The spacing between the connection portions prevents the interference between each jig and the holder. The cover has the insulating walls that are inserted into the gap corresponding to the spacing in a state of their having been mounted on the holder.
