Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a terminal fitting, and more specifically, to a tab suitably used as a terminal fitting for a tab end block.

[Prior art and its problems]

2. Description of the Related Art Conventionally, various terminal blocks have been proposed as electrical components for orderly connecting a large number of complicated electrical wirings for the convenience of consumers.

By the way, among these types of terminal blocks, the tabs (terminal fittings) in a terminal block called a tab end block, which has a plurality of output terminals for one input terminal, are, for example, as shown in FIG. Since it is composed of a combination of multiple parts, namely a flat tab part A, a tab part B with both ends bent at approximately 45 degrees, and a tab part C with both ends bent at approximately 90 degrees, these It is necessary to rivet the tab parts A, B, and C of the terminal block to the terminal block main body D with the tab parts A, B, and C stacked one on top of the other in order. Therefore, assembling the terminal block becomes troublesome, and consideration must be given to the contact area between each part. There were problems such as the need for

[Means for solving problems]

Therefore, in this invention, a plurality of cuts are symmetrically formed in a material such as brass from one opposing side edge of a rectangular plate substantially parallel to the other opposing side edge, and the rectangular plate is cut along the cuts. A strip-shaped stacked body is formed by bending it in a zigzag shape, and then both ends of this strip-shaped stacked body are sequentially bent at a predetermined angle to form a plurality of terminal blocks to form tabs (terminal metal fittings). This is intended to facilitate component management and assembly into a terminal block.

In this case, it is preferable to provide a rivet insertion hole in the center of the stacked strips forming the tab.

[Effect]

The tab according to this invention is formed as a single unit with each terminal part bent at a predetermined angle, so it can be assembled into a terminal block by simply fixing it to the terminal block body with rivets. It is.

〔Example〕

Next, preferred embodiments of the tab according to the present invention will be described in detail with reference to the accompanying drawings.

In FIGS. 1 to 4, tab 1 according to the present invention
0 consists of a rectangular plate body 12 made of a brass plate with a thickness of about 0.8 mm and solder-plated, for example.
A cut 1 is made approximately parallel to the opposite side edges 14, 14 of the rectangular plate 12 to the other opposite side edges 16, 16.
8a, 18b, 20a, 20b are extended symmetrically (see FIG. 1), and the rectangular plate 12 is bent in a spiral shape along each of the cut lines 18, 20 to form a strip. It is formed as a superimposed body 22 (see FIG. 2), and both ends of the strip-shaped superimposed body 22 are sequentially cut from above.
The terminal portions 24 are formed by bending them at angles of 90 degrees and 45 degrees, respectively, and a rivet insertion hole 26 of a predetermined diameter is drilled in the center of the stacked body 22 (see Fig. 3). ).

In this case, at the stage of extending the notches 18 and 20 in the rectangular plate 12, the tip angle of each terminal portion 24 is cut obliquely, and a receptacle fixing hole 28 for the connected wiring is provided in the center of the tip. is preferable.

When constructing the tab end block A as shown in FIG. 4 using the tab 10 according to the present invention constructed in this way, the rivet insertion hole 26 of the tab 10 and the rivet insertion hole 3 of the terminal block main body 1 are connected. The rivet 5 may be inserted by aligning the rivets 5 and 5, and the lower end of the rivet 5 may be caulked to be fixed to the terminal block main body 1.

[Effect of idea]

As mentioned earlier, the tab according to the present invention is constructed by bending a single plate, which not only reduces the number of parts, but also reduces the overlap and alignment work when assembling it into the terminal block body. It has various advantages such as being unnecessary and also being able to reduce unit costs, and its practical effects are extremely large.

Although the preferred embodiment of the tab according to the present invention has been described above, the present invention is not limited to this embodiment. It goes without saying that various modifications can be made without departing from the spirit of the present invention, such as changing the bending angle of the terminal portion or changing the bending angle of the terminal portion as appropriate.
