Embodiment Construction

[0054] Specific embodiments related to the present invention will be described below with reference to the accompanying drawings.

[0055] figure 1 (A) to 1(D) are diagrams for explaining a method of manufacturing an electric wire with a waterproof plug according to an embodiment of the present invention, in which figure 1 (A) to 1(D) are diagrams for explaining each processing.

[0056] Such as figure 1 As shown in (A) to 1(D), the method is a method of manufacturing an electric wire with a waterproof plug, in which the electric wire W is coated with an insulating coating Wb on the outer periphery of a conductor (core wire) Wa The insulating coating Wb is peeled off to prepare an exposed conductor portion Wa1 having a predetermined length from the end edge We of the electric wire W, and in which a cylindrical waterproof plug 10 is mounted on the near side (the side away from the end edge We) of the exposed conductor portion Wa1. Connected to the outer periphery of the i...

Abstract

A method of manufacturing an electric wire with a waterproof plug, the method including a first process of forming a notch 1 in an insulation coating at a position that is away from a tip edge We of the electric wire W by a predetermined length, for stripping off the insulation coating Wb1 of the tip edge We side from that position; a second process of inserting the tip of the electric wire W withthe notch 1 formed in the insulation coating Wb in the first process into the waterproof plug 10, and attaching the waterproof plug 10 on the outer periphery of the insulating coating Wb so that theposition where the notch 1 is formed is located on the front side of the waterproof plug 10; and after the second process, a third process of stripping off the insulation coating Wb on the front sideof the notch 1 to form the exposed conductor portion Wa1.

Description

technical field [0001] The present invention relates to a method of manufacturing an electric wire with a waterproof plug, wherein the waterproof plug to be incorporated into a waterproof connector is pre-attached to the end of the electric wire. Background technique [0002] For example, when assembling a waterproof connector, a rubber waterproof plug is attached to the outer circumference of the end of the electric wire, and a terminal fitting is connected to the end of the electric wire. The waterproof plug is crimped to the insulating covering portion of the electric wire through the terminal fitting. Next, the terminal fitting is inserted into the terminal accommodation chamber of the connector housing, and the waterproof plug is pushed into the terminal accommodation chamber so that the waterproof plug comes into close contact with the inner wall surface of the terminal accommodation chamber. Thus, the waterproof plug serves to close the gap between the inner wall sur...
