Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device for connecting terminals of wire wrapping terminals.

When connecting multiple terminals in parallel or short-circuiting a terminal board or connector used in electronic equipment, etc., on which a plurality of wire wrapping terminals are implanted, conventionally, as shown in FIG. The connecting plate 2 having the required number of terminal holes is inserted and mounted, and each wire wrapping terminal 11 and the connecting plate 2 are connected by soldering 3.

Alternatively, as shown in FIG. 2, required wire wrapping terminals are connected by wrapping with a common wire 4.

However, in the former case, it is difficult to solder in a narrow valley-like area, and it is difficult to expect a sufficiently reliable soldering.
In addition to the risk of dulling of the terminals due to residual flux and heating, soldering requires a long time.

In addition, the latter also has problems such as the wrapping and connecting work takes a long time and the number of connection wires to be connected is one for each terminal, which may prevent connection to the bone. there were.

In view of the above-mentioned conventional problems, the present invention aims to provide a terminal connecting device that eliminates these drawbacks.To achieve this purpose, the present invention has a first structure that is provided with a hole that can be inserted into a pair of wire wrapping terminals to be connected. The hole pitch of the first terminal connection plate is larger than the pitch of the wire wrapping terminal, and the hole pitch of the second terminal connection plate is larger than the pitch of the wire wrapping terminal. The pitch of the wire wrapping terminals is smaller than that of the terminals, and the first terminal connecting plate and the second terminal connecting plate are inserted into the wire wrapping terminal in contact with each other, thereby forming a pair of wire wrapping terminals based on the difference in mutual hole pitch. The reel at the end of the hole in the first terminal connection plate contacts the end of the hole in the second terminal connection plate in a drawing manner to connect the pair of wire wrapping terminals.

Furthermore, the terminal insertion hole is formed in a funnel shape, and with this configuration, it is possible to easily connect the terminals to be connected as required all at once with almost one touch. It has the advantage of requiring only an extremely small amount of space.

The embodiments of the present invention will be described below with reference to the accompanying drawings.

Figure 3 is a plan view of the terminal connection board according to the present invention, and figure a is the first
Figure b is the second terminal connection plate.

The first terminal connection plates 6 made of a conductive material are arranged vertically in the form of 4 in the figure.
Each of the terminal insertion holes 61 in the horizontal direction in the drawing is formed in an oval shape.

The center pitch 62 of each of the opposing semicircles in the horizontal direction of this column is larger than the pitch of the wire wrapping terminals described later, and the center pitch 62 of each of the opposing semicircles in the horizontal direction is larger than the pitch of the wire wrapping terminals described later. The center pitch 72 of the semicircle is smaller than that of the wire wrapping terminal.

With the above configuration, as shown in the side view of FIG. 4, the second terminal connecting plate 7 is inserted and attached to the wire wrapping terminal 11 to be connected as required of the connector 1, and then the first terminal connecting plate 6 is inserted and attached. do.

Then, the wiring 5 to be connected to other main circuits is connected to each terminal 11 by wrapping.

A plan view of this state is shown in FIG. 5, a representative detail of section A in FIG. 5 is shown in FIG. 7, and a side cross-section is shown in FIG.

As is clear from the above figures, the pitch 62 of the first terminal connection plate 6 is larger than the pitch 12 of the pair of left and right terminals 11. , the corner B is in contact with the semicircle of the hole 61, and B contacts the corner of the terminal, and the other terminal connecting plate 7 is in the opposite relationship with the hole 71.
It contacts the semicircle at A and A.

That is, when inserting and mounting the second terminal connection plate, the pair of terminals are pulled together, and when the first terminal connection board is inserted and mounted, they are pushed back against each other, so that the two connection plates are aligned as shown in the figure. When they are in contact with each other, they are in contact with each other by biting in an amount based on the pitch difference, so that the required terminals are reliably electrically connected through these connection plates.

The above relationship shows the same effect even if the insertion order of the terminal connection plates is changed.

Next, another embodiment of the present invention is shown in FIG.

FIG. 8 shows a first terminal connection plate 8 having a structure similar to that shown in FIG. 3, and a second terminal connection plate 9 in FIG.

The difference between this embodiment and FIG. 3 is that the terminal insertion holes 81 and 91
This is because it is shaped like a funnel.

Connect these terminal connection plates to the terminals 11 of connector 1 in the same manner as described above.
Figure 9 is a side view of the state in which it is inserted and attached, and Figure 10 is a plan view.
FIG. 11 shows a side cross-section of the main part of the D section, and FIG. 12 shows a plain view thereof.

As shown, the second terminal connection plate 9 and the first terminal connection plate 8
are inserted and mounted with their plate surfaces facing each other, that is, with their funnel-shaped protruding surfaces facing outward.

Both terminal connecting plates 8.9 installed in this way are arranged such that the holes in one terminal connecting plate are E,
It contacts at E, and it contacts at F and F with the hole of the other terminal connection plate.

Since this terminal insertion hole is funnel-shaped, insertion into the terminal is easy, and since the inner surface of the funnel-shaped hole and the terminal have a long contact length, electronic connection is suitable.

The present invention is not limited to the above-mentioned embodiments; for example, the terminal insertion hole may have any shape such as an ellipse or a perfect circle. There is no particular restriction on the size and shape as long as they are formed in a shape that functions to act and contact the terminals in different directions.

Further, the relationship between a pair of terminals is not limited to the horizontal direction in the drawings, but may be a vertical combination or even an oblique direction.

In addition, for example, in the case of three terminals, all three terminals can be connected by creating a pair of combinations for each of the three terminals and constructing the connecting device of the present invention.

In short, it is easily understood that by doing this, it is possible to provide an arbitrary number of terminal connecting devices from at least two terminals, and that the arrangement thereof is not limited to the illustrated embodiment, but can be implemented in any suitable arrangement.

Further, the present invention is applicable not only to connectors but also to any device having a wire wrapping terminal.

As described above, the present invention easily and reliably connects multiple required terminals at the same potential by inserting and mounting a terminal connecting plate made of two conductive materials, which are configured so that the pitch of the terminal insertion holes is different from the terminal pitch. It is possible to connect all at once so that the wire wrapping can be made, and the space required for this is approximately the same as the thickness of the board, so there is little need to reduce the space for wire wrapping.

In addition, it has excellent practical effects, such as being able to make any size and connect the required number of terminals in a short time.
