Description

[Detailed Description of the Invention] - Industrial Application Field The present invention relates to a terminal that is used by being attached to the end of an electric wire, and more specifically, it makes a novel proposal regarding the conduction structure between the terminal and the electric wire. .

Conflicts with the Prior Art and Its Problems FIG. 1 shows a conventional terminal, in which a wire holder 02 is protruded from the base of a terminal base O1 which is semicircularly bent and open at the top, and a core wire holder 03 is provided in the middle. An electric wire 04 with a protruding structure and an insulating coating stripped is inserted into a terminal base material 01 as shown in the figure, and a wire presser 02 presses the coating portion and a core wire presser 03 presses the core wire portion.

For this reason, when attaching a terminal, it is first necessary to strip the electric wire 04, and since the stopped core wire part is scattered and difficult to enter into the terminal base material O1, it is necessary to twist it by hand to eliminate the unevenness. It was necessary. Also, when installing the terminal, check the tip 06 of the core wire 05.
and whether the tip 07 of the coating is in the specified position, whether the core wire 05 does not protrude, whether there is no breakage of the core wire, and whether the tensile strength is sufficient. It was necessary to pay close attention to this and use expensive tools.

OBJECTS OF THE INVENTION The object of the present invention is to overcome the above-mentioned drawbacks of the prior art by proposing a terminal that can be installed without stripping the insulation coating.

・Structure of the present invention In order to achieve the above-mentioned object, the present invention provides a terminal base that is semicircularly bent and open at the top, and at the base of the terminal base, a holding piece for holding wires is integrally provided with the terminal base material, and an intermediate We propose a terminal in which a conductive claw piece is integrally provided with a terminal base material.

This terminal is inserted into the terminal base material with the insulation coating intact, the wire is held down with the holding piece, the conductive claw piece is bent and the tip is inserted from the insulation coating to the core wire, thereby establishing continuity between the terminal and the core wire. The aim is to

・Example Figures 2 to 7 show examples of the present invention. 1 is a terminal base material made by bending a phosphor bronze plate semicircularly and opening the upper part. The holding pieces 2.2a of the wire holding wire are protruded upward from the left and right edges, and the conductive claw pieces 3.2a are disposed upwardly from both left and right edges in the middle.
3a is protruded from the left and right. Note that the conductive claw piece 3.
The tip of 3a is sharpened so as to penetrate into the insulation coating and core wire of the electric wire.

4 is inside the terminal base material l, and there is a U-shaped slit 5 in the center.
A conductive plate 6 is provided between the holding piece 2.2a and the conductive claw piece 3.3a, and 6 is a stopper projecting forward of the conductive claw piece 3.3a.

To obtain a terminal having the above structure, as shown in FIG. 4, insert the electric wire 7 into the terminal base material 1 until the tip 7a of the wire hits the stopper 6, and use a tool to insert the holding piece 2, as shown in FIG. 2a and press the electric wire 7, at the same time force the electric wire i7 into the slit 5 of the conductive plate 4 to cut the insulation coating of the electric wire 7, and bring the core wire 8 and the conductive plate 4 into contact as shown in FIG.
Furthermore, the conductive claw piece 3.3a is bent and its tip is inserted into the electric wire 7 and into the core wire 8 as shown in the fifth factor.

- Effects of the present invention As described above, the present invention provides the terminal base material 1 with the holding piece 2.2a and the conductive claw piece 3.3a. , 2a leads to wire 7
In order to electrically connect the terminal base material 1 and the core wire inside the wire 7 by holding it down and inserting the conduction claw piece 3.3a into the wire 7,
You can expect the following effects.

a. There is no need to strip the wire 7, so the number of steps required for stripping and the core! There is no variation in i8, and there is no need to twist each core wire 8 for terminal attachment.

b. By piercing the conductive claw piece 3.3a into the core wire 8 within the electric wire 7, the electric wire 7 is locked by the conductive claw piece 3.3a, so that tensile strength can be ensured at the same time.

When the C6 conduction plate 4 is provided, in addition to the conduction effect provided by the conduction claw pieces 3.3a, the conduction area is further increased, so that the conduction state becomes even better.

d. There is no need to inspect the condition of the strip, the protrusion of the core wire, the position of the tip of the core wire, etc., as in the past.
