As shown in the figure, it is attached to the substrate 2 by fitting and inserting the protrusions 1a, 1a into a pair of through holes 2a, 2b formed at the ends of the substrate 2. Further, a plurality of such board connection terminals 1 are arranged in parallel, and each terminal 1 is attached to the board 2 in which the through holes 2a, 2a are formed in parallel by fitting the through holes 2a and the projections 1a, respectively, By inserting the leg portions 1b of each terminal 1 into the inserted portion of another electronic device component (not shown), the board 2 and the other electronic device component are connected.

The reasons for attaching such conventional board connection connections 1 to the board 2 at the same time are that it is difficult to position the protrusion 1a with respect to the through hole 2a, and that it is difficult to line up a large number of board connection terminals 1. Therefore, it is extremely difficult. Therefore, each terminal 1 is fitted by manually fitting the protrusion 1a into the through hole 2a one by one.
The conventional mounting method was to attach each one to the end of the board 2 one by one. It takes a lot of man-hours to attach each terminal 1 to the board 2 in the conventional method.
The mounting accuracy on the substrate 2 was also not desirable.

OBJECT OF THE INVENTION The present invention was made in order to eliminate the drawbacks of the conventional board connection terminals and their attachment methods as described above, and it is possible to attach a plurality of terminals to a board at the same time. It is an object of the present invention to provide a terminal device for connecting a board that is not easily affected by heat during solder bonding.

Structure of the Invention The terminal device for connecting a board according to the present invention has a mounting part for attaching to an end of a board and a leg part for connecting to a component such as another board, and a terminal device for connecting a board by using the mounting part. A terminal device for connecting a board consisting of a plurality of terminals attached in parallel to an end, in which the tip of each terminal on the mounting part side and the tip on the leg side are respectively connected to a band-shaped member and become integral. Furthermore, a bending/separating thin part for separating each of the terminals from the strip member is formed at or near the connecting part. In the board connection terminal device according to the present invention configured as described above, the parallel terminals are connected to form a single unit, so each terminal can be handled as a unit until the terminal device is attached to the board. , it becomes possible to attach multiple terminals to the board at the same time. In addition, the above-mentioned board connection terminal device has a thin part for bending and cutting, such as a notch, for separating each terminal from the strip member. Each terminal can be separated. Further, in the terminal device for connecting a board according to the present invention, since the protrusion serving as the attachment portion is formed by bending the portion surrounded by the U-shaped or key-shaped sheared portion at the unsheared portion, the protrusion Its own cross-sectional area is small, making it difficult to conduct heat, and can prevent the adverse effects of heat during soldering.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 3 shows an embodiment of the terminal device for connecting a board according to the present invention. In FIG. 3, 10 is a terminal device for connecting a board, and this terminal device 10 for connecting a board has a mounting part and a leg part, which will be described later.
Plural parallel board connection terminals 11, 11...
11, and an attachment part side band member 12 and a leg side band member 13 that connect these together.

The board connection terminal 11 has a pair of protrusions 11a, 11a extending perpendicularly to the parallel direction of the terminals 11 and parallel to each other, and a leg portion 11b extending perpendicularly to the longitudinal direction of the protrusions 11a. have The protrusion 11a extends from the center of each terminal 11 to a U
The part C surrounded by the sheared part in a letter shape (or inverted U shape) is the unsheared part D left without being sheared.
It has a bent shape, and this is the shape of each terminal 1.
1 to the edge of the board.
Further, the leg portions 11b are provided for connecting each terminal 11 to components such as other boards,
In the embodiment shown in the figure, the tip has a pointed shape to facilitate insertion of components such as other boards into the inserted portion.

In the board connection terminal device 10, the width is narrowed in the vicinity of the connecting portion between each terminal 11 and the mounting portion side band member 12, more specifically in the vicinity of the connecting portion, which is sheared to form a protrusion. In the part where
V-shaped attachment part side notches A and A are formed on the front and back sides, and serve as thin parts for bending and dividing. Further, V-shaped leg side notches B are formed on the front and back near the connection portion between each terminal 11 and the leg side band member 13,
This is a thin section for bending and dividing.

The part where the above-mentioned mounting part notches A and A are formed has been sheared to form a protrusion and has a narrow width, and since a notch is formed, the cross-sectional area is small, and the stress due to the notch is reduced. Due to the concentration effect,
It can be easily bent and separated at that part.

In FIG. 3, reference numeral 12a is a guide hole used when the hoop material, which is the material of the board connection terminal device 10, is intermittently fed for processing.

Using the board connection terminal device 10 as described above, the through holes 2a, 2a, . . . formed at the end of the board 2 are used.
When attaching each terminal 11 to the substrate 2 by fitting the protrusion 11a of each terminal 11 into the through hole 2a, first, the terminals 11 are provided in a sufficient number to fit all the protrusions 11a into the through hole 2a. The board connection terminal device 10 is cut into a predetermined length. Specifically, the board connecting terminal device 10 of a predetermined length is obtained by cutting at the mounting part side band member 12 and the leg side band member 13. Furthermore, when fitting the protrusion 11a into the through hole 2a, the mounting part side band member 12 is inserted into the mounting part side notch A.
The notch A produces a stress concentration effect and has a small cross-sectional area, so it can be easily bent and separated by hand.

As described above, the board connection terminal device 10 is cut into a predetermined length and the mounting portion side strip member 12 is separated and removed, and the protrusions 11a, 1 of each terminal 11 are cut into a predetermined length.
1a is the through hole 2a formed at the end of the substrate 2.
Insert and fit as shown by the arrow in Figure 4,
Each terminal 11 is fixed by caulking a predetermined portion of the board 2. In this case, the distance between the pair of through holes 2a, 2a and the pair of through holes 2a, 2a formed adjacent to each other is the distance between the adjacent terminals 11, 11 of the board connection terminal device 10. Of course, they are set to be equal.

Furthermore, after fitting each protrusion 11a into each through hole 2a and fixing each terminal 11 to the board 2, each leg side strip member 13 is bent and separated at the leg side notch B. The terminals 11 are separated from each other. In this case, since a stress concentration effect also occurs in the leg side notch B, it is possible to easily bend and separate it by hand.

The board connection terminal device 10 as described above has the protrusions 11a, 11a of each terminal 11 connected to the through hole 2 of the board 2.
A, 2a can be treated as one body until it is fitted and inserted, so the protrusion 11 for the through hole 2a
It becomes easy to position a, and it becomes easy to align each terminal 11. Therefore, it becomes possible to attach a plurality of terminals 11, 11, . . . , 11 to the substrate 2 at the same time, and automation thereof is also easy.

Furthermore, the board connection terminal device 10 can be easily manufactured by applying shearing and bending to a hoop material as its raw material, and further processing to form a notch.

Next, other embodiments of the present invention will be described with reference to the drawings.

FIG. 5 shows another embodiment of the board connection terminal device of the present invention. In Figure 5,
Reference numeral 20 denotes a board connection terminal device, and this board connection terminal device 20 includes a plurality of board connection terminals 2.
1, 21...21, and an attachment part side band member 22 and a leg side band member 23 that connect these together.

The board connection terminal 21 has a pair of protrusions 2 extending in parallel, similar to the embodiment described in FIG.
1a, 21a, and leg portions 21b extending perpendicularly to the longitudinal direction of the protrusions 21a. It differs from the embodiment described in FIG. 3 in that it is formed by bending the unsheared portion H left without being sheared.

It goes without saying that the board connection terminal device 20 is also formed with a mounting section side notch E and a leg section side notch F for separating each terminal 21.

The board connection terminal device 20 can also be handled as one unit until the protrusions 21a, 21a of each terminal 21 are fitted and inserted into the through holes 2a, 2a of the board 2, so a plurality of terminals 21, 21... 21 to the substrate 2 at the same time.

In each of the above embodiments, in order to form a thin part for bending and dividing, a V-shaped notch was formed near the part where both ends of each terminal were connected to the strip member. However, a V-shaped notch may be formed in the connecting portion itself. Further, in the above-described embodiment, the thin part for bending and dividing is formed by providing a V-shaped notch, but it can also be formed by providing a square groove-like notch, for example. Furthermore, the bent and divided thin-walled portions may be formed by simply reducing the thickness of the portions. Further, although the V-shaped notch is formed on the front and back sides, it is also possible to form it on only one side.

In addition, in the above-mentioned embodiment, each terminal has a sharp tip, but the leg of each terminal has the same width as the center, that is, the tip of each terminal has a sharp shape. Needless to say, it doesn't have to be anything particularly sharp.

Furthermore, when attaching the board connection terminals 10 and 20 to the board 2, the attachment part side strip member 1
2 and 22 are bent and separated in advance and removed. However, after the board connection terminals 10 and 20 are attached to the board 2, the mounting part side strip member 1 is removed.
2 and 22 may be removed by bending and dividing.

The board connection terminals 10 and 20 are connected to the board 2 and other parts through the protrusions 11a and 21a and the legs 11b and 21b, and both parts are soldered. Terminals 10, 20
The central portion of the tube is sheared and bent into a U-shape or key-shape to form the protrusions 11a and 21a, so the cross-sectional area is small, making it difficult to conduct heat. Therefore, when the board connection terminals 10 and 20 are used, when soldering both the protrusions 11a and 21a and the legs 11b and 21b, there is no possibility of heat conduction and adverse effects on each other. There is an advantage.

Effects of the Invention As detailed above, the board connection terminal device of the present invention has a plurality of board connection terminals that are attached to the edge of the board and connects other electronic equipment components arranged in parallel, and also uses a strip member. Since the terminals are connected and integrated, the terminals can be handled at the same time until they are attached to the end of the board. Moreover, each terminal and the above-mentioned band-like member are formed by a thin part for bending and dividing, which is formed in advance.
For example, by using a notch, it can be easily bent and separated by hand, and each terminal can be easily separated and separated after being attached to the board.
Therefore, the terminal device for board connection according to the present invention significantly improves the workability when attaching the terminal to the board, and the terminal device has a U-shaped or key-shaped protrusion as the mounting part. It is formed by bending the sheared part from the unsheared part, and since the cross-sectional area of the protrusion itself is small and heat conduction is difficult, it can ultimately prevent the adverse effects of heat when soldering the terminal. It is something.
