Problems solved by technology

In order to avoid this situation, it is also considered to provide a separate positioning member to place the core wire at a constant position, but there is a problem that not only the assembly of the jig becomes complicated, but also the number of welding steps increases.

Embodiment approach 1

[0039] based on Figure 1 to Figure 12 Embodiment 1 will be described. Such as Figure 10 As shown, the terminal-equipped electric wire 10 of this embodiment has a structure in which a bus bar 20 (equivalent to a terminal) is connected to the end of a covered electric wire 11 (equivalent to an electric wire) by ultrasonic welding, and is suitable for, for example, a battery mounted on an electric vehicle. Wiring parts such as modules.

[0040] Such as figure 1 As shown, the covered electric wire 11 has a structure in which the outer periphery of a core wire 12 is covered with an insulating coating layer 14 made of synthetic resin. At the terminal end of the covered electric wire 11, terminal processing is performed to expose the core wire 12 by peeling off the insulating coating layer 14 by a predetermined length.

[0041] The bus bar 20 is made of a relatively thin metal plate, such as figure 1 As shown, it is formed in a square plate shape in plan view, and the side o...

Embodiment approach 2

[0059] exist Figure 13 In Embodiment 2 shown, the shape of the welding horn 40X is changed. That is, the core wire 12 for covering the electric wire 11 is formed on the lower surface of the pressing portion 41 of the welding horn 40X for ultrasonic welding (refer to figure 2 ) embedded in the pressing groove 45 of circular arc cross-section.

[0060] In the welding process, the core wire 12 is pressed to the positioning groove 23 of the wire connection part 21 in the bus bar 20 by the top surface of the pressing groove 45 of the welding horn 40 (refer to figure 2 ), and ultrasonically vibrate the core wire 12 along the axial direction to perform ultrasonic welding.

[0061] Since the core wire 12 is more reliably positioned in a state sandwiched between the positioning groove 23 and the pressing groove 45, ultrasonic welding can be performed more appropriately.

Embodiment approach 3

[0063] In Embodiment 3, other changes are added to the shape of the welding horn 40Y. That is, if Figure 14 As shown, a pressing protrusion 47 having an arc-shaped cross section may be formed on the lower surface of the pressing portion 41 of the welding horn 40Y.

Abstract

A method for manufacturing a cable with a terminal (10), for which a core wire (12) of a cable (11) is connected to a flat plate-shaped cable connector part (21) provided on a terminal (20). An ultrasonic welding jig (30) comprising an anvil (31) and a welding horn (40) is provided. After the cable connector part (21) of the terminal (20) is placed on the anvil (31), the core wire (12) of the cable (11) is placed on the cable connector part (21). By applying ultrasonic vibration along the axis direction of the core wire (12) while pressing on the core wire (12) using the welding horn (40), thecore wire (12) is ultrasonically welded to the cable connector part (21). On the top surface of the cable connector part (21) of the terminal (20), a positioning groove (23), into which the core wire(12) of the cable (11) is fit, is formed in advance, and the core wire (12) is placed on the cable connector part (21) while being fit into the positioning groove (23).

Description

technical field [0001] The present invention relates to a method of manufacturing an electric wire with a terminal and an electric wire with a terminal. Background technique [0002] A structure is known in which ultrasonic welding is employed in the case of connecting the end of the core wire in the electric wire to the bus bar. Specifically, an ultrasonic welding jig composed of an anvil and a welding horn is provided, and the core wire of the electric wire is placed on the bus bar after the bus bar is placed on the anvil, and the core wire is pressed by the welding horn while the bus bar is placed on the anvil. While applying ultrasonic vibration along the axial direction, the core wire is ultrasonically welded to the bus bar (see Patent Document 1 below).
