Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a method for forming a ground wire terminal in which a terminal can be formed at any location using a braided wire.

(2) Problems with conventional technology Conventional ground wires (earth busbars) are made by punching out two strips of copper plate, as shown in Figures 1 and 2.

A terminal 2 was formed on the side thereof to serve as a ground wire 1.

Because of this, its length is determined by the standard length of the material, and care must be taken to avoid bending it when storing and handling it. If you need a long one, use the protrusion 3 as shown in Figure 1.
Connect by soldering using the connecting fitting 4. In the case of a rack like this, it is necessary to connect several long integrated connectors, and in the case of a rack arranged horizontally on the rack shelf as shown in Figure 2, many terminals must be connected to correspond to each connector. I need.

On the other hand, the ground wire has many cut pieces to form terminals, which wastes material and takes a lot of processing time. Also, while the one in Figure 2 has versatility, if it is implemented for each,
Not connected to all terminals.

There are many things that are idle. Due to its good thermal conductivity, a large soldering iron must be used for soldering, and it is difficult to ensure reliability with a relatively small soldering iron; (3) Purpose of the Invention The present invention was made in view of the above problems. The object of the present invention is to provide a method for forming a terminal, which allows a terminal to be arbitrarily placed at a desired location and used as a ground wire.

(4) Structure of the invention The above object is achieved by the following requirements which are the gist of the structure of the method of the present invention. That is, this method of forming a ground wire terminal is characterized in that both ends of a plate terminal fitting that holds a band-shaped braided wire across its width are folded back and the braided wire is pressed and connected.

(5) Examples of the invention The method of the present invention will be specifically explained below with reference to Examples.

FIG. 3 shows a perspective view of an embodiment of the terminal fitting 5 according to the present invention. A hole 6 is made in the center of a rectangular metal plate with good electrical conductivity, and one end 7 is folded back.

At the other end, the protruding solder is cut and bent, leaving the connecting terminal 8 portion, and is folded back 9.

As shown in FIG. 4, a known band-shaped braided filament 10 having a predetermined width can be easily inserted between the opposing folded widths. The braided filament 10 is made by braiding a large number of thin copper wires into a long, flat belt-like shape, and some are made of plated copper wire.

In the state shown in FIG. 4, the terminal fitting 5 is set at a desired position in the length direction with respect to the braided wire 10, and at that position, while regulating the width direction, it is folded back in the thickness direction and 7.9 is pressed into contact with the braided wire 10 securely. Braided wire 1
Fixed connection to 0. A plurality of terminal fittings 5 are used, and each terminal fitting 5 is pressed and fixed only at a required location, and a braided wire 10 is cut to a required length to form a ground wire.

The braided wire 10 has appropriate flexibility and can be used as a frame.

To attach it to a casing, I, etc., the part corresponding to the hole 6 of the end fitting 5 is expanded and a mounting hole (not shown) is inserted. Connect the grounding wire to terminal 8 by soldering.

FIG. 5 shows a different embodiment according to the invention. In this embodiment, two braided wires 10 are arranged in parallel, and each is fixed by pressing at both folds 7 and 9.

This is convenient for branching and combining the ground wires. This is not possible in a parallel state (by overlapping the braided wires, the number of braided wires can be set to an arbitrary number. Branch 1 synthesis can be directed in any direction based on the flexibility of the braided wires.

When the ground wire according to the present invention needs to be fixed in the middle or at the end, it is possible to use the holding metal fitting 11.1 shown in FIG.
2 to insert and install the screws into the holes 13 and 14. Of course, the two braided wires 10 are inserted between the folds at both ends of the holding fitting 11 and crimped.

Different embodiments of the terminal fitting are shown in FIGS. 7 and 8.

In Figure 7, the terminal 15 is elongated and a ground wire can be connected by means of wire wrapping, and in Figure 8, the terminal 16 is provided with a flat wedged hole 17 for connection to a screw lug terminal, etc. It is possible.

(6) Effects of the Invention As described above, according to the method of the present invention, since a long braided wire is used, the braided wire can be simply cut to the required length without requiring any special processing.

Terminal fittings can be easily attached and formed only in required parts. In addition, the length is not limited, and it can be bent freely, and it can also be rolled up for storage, transportation, etc. That direction is the direction of the terminal of the terminal fitting.

The shape can be arbitrary, and the practical effect is remarkable, such as making the folded end portion serrated to further ensure pressure contact.
