Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a composite flat terminal. This relates to flat terminals.

(Prior art) When fixing the ends of multiple wires together in one place, the wire connection parts provided on the terminals do not overlap each other, and the flat terminal body parts with bolt insertion holes are in close contact with each other. As composite flat terminals configured to be attached to the bolts of electrical equipment in the state shown in Fig. 4 a, b and Fig. 5 a, b, for example, the ones shown in Fig. reference).

According to this composite flat terminal, the tongue piece 120 is provided on the outer periphery.
(see FIG. 4a), and a large terminal 200 (see FIG. b), and by passing the tongue piece 120 of the small terminal 100 through the bolt insertion hole 230 and rotating the small terminal 100 in the direction of arrow A (see FIG.
It is designed to be locked in place.

As a result, as shown in FIG.
0 and the wire connecting portion 240 of the large terminal 200 do not overlap each other, and the flat terminal main body portions 110 and 210 are coupled in close contact with each other. Therefore, when assembling to the bolt of electrical equipment, the wire connection parts 140, 24
The terminal body portions 110 and 2 overlap each other.
Assembling defects such as gaps between the holes do not occur.

Note that a protrusion 250 is provided on the surface of the large terminal 200 (the surface on which the small terminal 100 overlaps), and is adapted to be engaged with the peripheral edge of the small terminal 100.

(Problem to be solved by the invention) In the above composite flat terminal, the tongue piece 120 and the claw 220
The small terminal 100 and the large terminal 200 are locked together by the locking between the small terminal 100 and the peripheral edge of the small terminal 100.
However, the engagement between the tongue piece 120 and the claw 220 is such that the small terminal 100 is moved in the direction of arrow B shown in FIG. 5b, and the large terminal 200 is moved in the direction of arrow C shown in the same figure. It can be easily removed by rotating (rotating away from each other), and the engagement between the protrusion 250 and the peripheral edge of the small terminal 100 is also similar to that of the small terminal 10.
0. When the large terminals 200 rotate in the direction away from each other, the small terminal 100 easily climbs over the protrusion 250 and comes off.

For this reason, the tape 400 is attached to the electric wires 300, 300 which are crimped and connected to the electric wire connecting portions 140, 240.
It was necessary to wrap the small terminal 100 and the large terminal 200 in place to prevent them from rotating away from each other, which was a time-consuming problem.

This invention was made to solve the problems of the above-mentioned conventional technology, and its purpose is to:
To provide a composite flat terminal capable of maintaining a connected state without wrapping tape around electric wires.

[Structure of the invention] (Means for solving the problem) In order to achieve the above object, the composite flat terminal of this invention has a bolt insertion hole in the flat terminal body and a continuous wire connection part. In a composite flat terminal in which two terminals are combined so that the terminal bodies overlap each other and the wire connection parts do not overlap each other, each of the two terminals is provided with a protrusion around the terminal body. A locking portion consisting of a lance provided on a hook or an upright piece formed around the terminal body so as to protrude outward; and a locking hole provided on the peripheral side of the terminal body or around the terminal so that the hook can be locked therein. When the two terminal bodies are overlapped with each other with the two terminal bodies facing each other, the locked part is formed of a locking hole provided so that the lance can be locked in the upright piece formed in the part. It is characterized in that the part and the locked part are arranged so as to face each other and can be locked.

In this invention, "the locking part and the locked part that can be locked facing each other when the terminal bodies are stacked facing each other" refers to the locking part (the locked part) of one terminal body. The locking occurs in the process of bringing the terminal bodies close to each other and overlapping them (see Figures 2 a and b) so that the locked part (locking part) and the locked part (locking part) of the other terminal body face each other. This means a locking part or a locked part, and is different from a conventional locking process in which one terminal is rotated clockwise, for example, with the terminal bodies stacked on top of each other.

(Function) Place the terminal body of one terminal and the terminal body of the other terminal in a state where the locking part and the locked part are facing each other, and then bring them close together. When the locking portion is locked, the wire connecting portion of one terminal and the wire connecting portion of the other terminal do not overlap each other, and the terminal bodies are connected in close contact with each other with a single touch. In this coupled state, even if one terminal and the other terminal are rotated so that the wire connecting portions separate from each other, this is prevented by the engagement between the locking portion and the locked portion, and the coupled state is maintained.

(Example) An example of this invention will be described below with reference to the drawings.

The figure is a perspective view showing a coupled state.

The reference numeral 10 in the figure is a small terminal (one terminal), and a bolt insertion hole 15 is provided in the center of a terminal body 11 formed in a flat plate shape and approximately elliptical shape. A rectangular locking hole 12 as a locked portion is provided in one peripheral portion. Further, an upright piece 13 is provided on the other peripheral portion of the terminal body 11 by bending the terminal body 11 and standing up almost at a right angle. It is provided. Furthermore, an electric wire connecting portion 14 extending in the short axis direction of the terminal body 11 and having a substantially U-shaped cross section is connected to a peripheral portion of the terminal body 11 near the locking hole 12 .

In addition, the symbol 20 in the figure is the large terminal (the other terminal)
A bolt insertion hole 25 is provided in the center of a terminal body 21 that is larger than the terminal body 11, has a flat plate shape, and is formed in an approximately elliptical shape. A step-shaped hook 22 is provided as a locking portion that locks with the stopper hole 12. Further, an upright piece 23 is provided near the other peripheral portion of the terminal body 21 by cutting and raising the terminal body 21 to stand up at a substantially right angle. A locking hole 23a is provided. moreover,
At the periphery of the terminal body 21 near the upright piece 23,
A wire connecting portion 24 extending in the short axis direction of the terminal body 21 and having a substantially U-shaped cross section is continuously provided.

In order to connect the small terminal 10 and the large terminal 20, the second
As shown in FIG.
First, the hook 22 is locked in the locking hole 12, and then the terminal body 11 is rotated toward the terminal body 21 using the locking portion between the locking hole 12 and the hook 22 as a fulcrum, and the lance 13a is inserted into the locking hole 23a. (See figure b). By this one-touch operation, as shown in FIG.
are combined in close contact with each other.

In such a state, if an attempt is made to rotate the small terminal 10 in the direction of arrow D shown in FIG. 3 and the large terminal 20 in the direction of arrow E shown in the same figure (the direction in which the wire connecting parts 14 and 24 separate from each other), Also, the locking hole 12
The small terminal 10 is blocked by the locking between the hook 22 and the lance 13a and the locking hole 23a.
The state of connection between the large terminal 20 and the large terminal 20 is maintained. Therefore, by wrapping tape or the like around the electric wires 30, 30 crimped to the electric wire connecting parts 14, 24, the small terminal 10
There is no need to maintain the connection state between the large terminal 20 and the large terminal 20.

In addition, in the above embodiment, the hook 2 is used as the locking part.
2. Although the lance 13a is provided and the locking holes 12 and 23a are provided as the locked portions, the present invention is not limited thereto. For example, small terminal 10
A hook 22 is provided in place of the locking hole 12,
