Embodiment 1

[0024] Below, refer to figure 1 Embodiment 1 which actualized the present invention will be described in detail with reference to FIG. 3 .

[0025] The electric wire 10 with terminal fittings in this embodiment includes a braided wire 11 and a pair of terminal fittings 12 connected to both ends of the braided wire 11 in the longitudinal direction.

[0026] The terminal fittings 12 are formed by pressing a sheet material made of a metal (for example, made of a copper alloy) having excellent electrical conductivity. The terminal fitting 12 has a connecting portion 13 which is connected to a machine or the like, and a cylindrical portion 14 which is connected to an end portion of the braided wire 11 , which are integrally formed. A through hole 15 is formed in the connecting portion 13 along the plate thickness direction, and a fastening member (not shown) such as a bolt can be inserted through the through hole 15 . The through hole 15 is formed as a long hole long in the long...

Embodiment 2

[0046] Next, a method of manufacturing the electric wire 10 with terminal fittings according to Example 2 embodying the present invention will be described.

[0047] In the method of manufacturing the electric wire 10 with terminal parts of this embodiment, after the winding step of wrapping the metal foil 18 around the cut portion of the braided wire 11, the cutting step of cutting the cut portion in the state where the metal foil 18 is wound is performed. It is different from Example 1. In addition, the same code|symbol is attached|subjected to the same structure as Example 1, and repeated description is abbreviate|omitted.

[0048] In the electric wire 10 with terminal fittings according to the present embodiment, as in the first embodiment, the metal foil 18 is wound around the end of the braided wire 11 and the terminal fitting 12 is connected thereto, and the end of the braided wire 11 is folded back in the width direction. overlapping state.

Abstract

An electrical wire with a terminal fitting that can be manufactured without using a welding device, and a method of manufacturing this electrical wire with a terminal fitting. Metal foil is wrapped around end portions of the braided wire, and terminal fittings are connected to the end portions. According to this configuration, the metal foil makes it possible to prevent strands in the end portions of the braided wire from becoming loose and spreading apart, and this makes it possible to manufacture the electrical wire with a terminal fitting without using a welding device.

Description

technical field [0001] The present invention relates to an electric wire with terminal parts and a method for manufacturing the electric wire with terminal parts. Background technique [0002] Conventionally, there is known an electric wire with a terminal component that is configured by crimping a terminal component to an end portion of a braided wire. The braided wire is formed by braiding multiple metal wires and cut into predetermined lengths. The end of the braided wire is set on the barrel of the terminal part, and the barrel is riveted. [0003] However, at the ends of the braided wires, the wires tend to unravel and spread. If the ends of the braided wire are scattered, the wire rod will be bitten between the barrel pieces of the terminal part, the tensile strength will decrease, and the contact resistance may become unstable in the diffused braided wire. Then, as described in Patent Document 1 below, it is known to form a crimped portion at an end portion of a br...
