Description

[Detailed description of the invention] This invention relates to a receptacle for tab terminals, and more specifically, to a receptacle for tab terminals that has a large contact area with tab terminals and can be attached to deformed tab terminals. It is.

A typical tab receptacle for a conventional tab terminal has a terminal portion for crimp-bonding a conductor wire at the center of one of the long side edges of a rectangular conductive metal plate, and both longitudinal ends of the tab receptacle.
The metal plate is bent at a substantially right angle to one side of the metal plate, and then the bent ends are curved to such an extent that the edges face each other and substantially touch the negative side to form a flat part and an elastic end surface part. is frequently used.

However, in this case, although it can be inserted into a flat tab terminal without considering the direction, it has the drawback that the line contact is made by the elastic end surface, which is dangerous because it generates heat from a large current. For special tab terminals whose parts are bent into a crank shape, there is a directionality when inserting them, and if they are inserted in the opposite direction, the elastic contact part will not work effectively and contact resistance will increase. There is a drawback that it becomes large.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and its characteristics are that it is a substantially flat rectangular elastic conductive metal plate with one longitudinal end side approximately parallel to the other side. Bend it 90 degrees and fold it back in an arc shape to the first side.
An elastically curved portion is formed, and the other end of the metal plate is bent approximately 90 degrees toward the other side, leaving a first flat portion on the other end side, and then folded back in an arc shape toward one side to form a second elastic curve. A second flat part is formed parallel to the first flat part at an interval slightly narrower than the thickness of the tab terminal from this elastic curved part, and the edge of this flat part is connected to the first flat part. Inserting the tab terminal by inserting the tab terminal into the inside of the edge of the curved portion so as to make contact therewith, and bending each of the projecting pieces formed on one of the sides of the first flat portion outward. The present invention provides a receptacle for a tab terminal, characterized in that an introduction part is formed to facilitate the insertion, and a wire fixing part is formed on the other side of the flat part.

An embodiment of your proposal shown in the drawings will be described in detail below.

FIG. 1 is an exploded view of the tab terminal receptacle of this invention, in which the tab terminal receptacle forming body 1 is substantially flat;
It is made of a rectangular elastic conductive metal plate, and has an elastic curved part 2a,
2b, a receptacle component A consisting of flat parts 3a and 3b, and protrusions 4a formed on the sides of each flat part.
, 4b respectively bent outward to facilitate the insertion of the tab terminal, and a receptacle component 11 and a receptacle component 11 located at a position approximately at a distance from one end at one side edge of the component. The electric wire fixing section 14 includes a crimp type electric wire fixing section 14 including first and second winding sections 15a, 15b and 16a, 16b for crimping and connecting the conductor.

As shown in FIG. 2, this tab terminal receptacle forming body 1 has a flat portion 3 located at one end of the receptacle component A
After bending a to one side along the broken line 7C, bend the elastic curved portion 2a to the other side by about 90 degrees along the broken line 7a (Fig. 1), and then add a length approximately + of the length of the elastic curved portion 2a. The first elastic curved portion 2a is created by folding it in an arc shape on one side so as to have the same diameter.
Similarly to the first elastic curved portion 2a, the second elastic curved portion 2b connected to the first flat portion 3a also extends approximately 90 degrees along the other side along the broken line 7b.
After bending, the second elastic curved portion 2 is folded back in an arc shape to one side so that the diameter is approximately l of the length of the elastic curved portion 2b.
b, and the second flat part 3b connected to this second elastic curved part by the broken line 7C is connected to the first flat part 3a with a gap slightly narrower than the plate thickness of the tab plug 13 as shown by the broken line in FIG. The receptacle part is completed by forming a parallel second flat part 3b and bringing the end side surface of this flat part into contact with the end edge of the first curved part to form a contact part B.

The tab terminal receptacle of this invention has the above-mentioned configuration, and its usage will be described below.

FIG. 3 shows a tab plug 13 which is crimped and connected to the core wire 11b of an insulated conductor 10b by a ferrule as an example of the counterpart of this tab terminal receptacle 9.
, 5b, and is inserted into the receptacle portion 8.

This receptacle 9 and a covered electric wire 10 as shown in FIG.
To connect the tab plug 13 attached to the tab terminal receptacle 9, connect the tab plug 13 to the first tab terminal receptacle 9. If the tab plug 13 is inserted between the second flat parts 3a and 3b, the first flat part 1. The second flat portions 3a, 3b are elastically brought into tight surface contact by the action of the elastic curved portions 2a, 2b, and can be joined with small contact resistance.

That is, as shown in FIGS. 2, 3, and 4,
1st. The introduction parts 5a, 5b of the second flat parts 3a, 3b are the outer edges 2a' of the first and second elastic curved parts 2a, 2b,
2a', and there is a continuous slope between them, so when inserting the tab plug 13 between the flat portions 3a and 3b, the tab plug 13 is in the direction of its thickness as shown in FIG. The roughly ■-shaped introduction parts 5a, 5
b begin to touch, and as it is inserted, the side edges of the flat parts 3 a and 3 b gradually come into contact with each other toward the center, and finally the flat parts 3 a ,
3b tightly contacts the entire surface of the plug 13, allowing smooth insertion.

As described above, this invention has a substantially flat rectangular elastic conductive metal plate with one end side in the longitudinal direction extending approximately 90 mm to the other side.
The gold conductive plate is bent at an angle of about 90° to the other side, and then bent again in an arc shape to one side to form a first elastic curved part, leaving a first flat part on the other end side of the gold conductive plate. After bending, it is folded back in an arc shape on one side to form a second elastic curved part, and from this elastic curved part, a second flat part parallel to the first flat part is formed at an interval slightly narrower than the thickness of the tab terminal. and bringing the edge of the flat portion into contact with the edge of the first curved portion,
and a protruding piece formed on one of the sides of the first flat part is bent outward to form an introduction part that facilitates insertion of the tab terminal, and Since the wire fixing part is formed on the other side, the contact resistance is low because it makes a tight surface contact with the tab plug over a wide range. By forming the second elastic curved portion and configuring the edges of the first and second flat portions to be located approximately at the center of the first and second elastic curved portions, the plane becomes symmetrical, and therefore both ends are It has the effect that even a tab terminal bent into a crank shape can be smoothly inserted without considering directionality.
