Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a lead straightening tool, and more particularly to a lead straightening tool for a DIP type IC.

[0002]

2. Description of the Related Art Conventionally, DIP (dual inline)
package) type IC (integrated)
circuit) is known. This IC has a structure in which a plurality of leads with their ends directed downward are arranged on both sides of the package. By inserting each lead into a receiving hole formed in the IC socket, the IC is connected to the IC socket. Can be attached to

When the lead is inserted into the receiving hole of the IC socket, the arrangement of the lead of the DIP type IC must be matched with the arrangement of the receiving hole. Need adjustment to match. Even if the lead is not new, if the lead is bent for some reason, adjustment is necessary.

[0004]

However, conventionally,
This adjustment is performed by pressing the leads against a flat surface, for example, so that the leads are arranged in a line. At the time of adjustment, the leads are pressed too much, and the leads are appropriately corrected so as to enter the IC socket. It was not easy.

An object of the present invention is to provide a lead straightening tool which can easily straighten a lead properly.

[0006]

In order to achieve the above object, a lead straightening tool according to the present invention is characterized in that when a plurality of leads arranged downward with respect to an IC package move in the arrangement direction, It has a straightening groove for guiding a plurality of leads and straightening and aligning them in a line.

With the above structure, the plurality of leads arranged downward with respect to the IC package are guided by the straightening groove so as to be straightened and aligned in a line when the plurality of leads are guided along the arrangement direction. Can be Thereby, the lead can be easily corrected appropriately.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a lead straightening tool according to an embodiment of the present invention. As shown in FIG. 1, the lead straightening tool 10 has a rectangular plate shape, and has two groove-shaped lead straightening portions (straightening groove portions) 11 that are open on the surface 10a.

The arrangement of the leads of the DIP type IC 12 can be corrected, for example, by the two lead correcting units 11 and 11. The DIP type IC 12 has an IC package 13 and a plurality of leads 14 arranged on both sides of the IC package 13 with their tips directed downward.

[0011] The two lead straightening units 11, 11 are DIP
The plurality of leads 14 arranged side by side of the mold IC 12 are arranged side by side according to the arrangement of the plurality of leads 14 arranged side by side so that both sides can move at the same time on both sides.

Each lead correcting section 11 has, at one end, an inlet 15 for introducing each lead 14 and at the other end an outlet 16 for discharging each lead 14, and moves between the inlet 15 and the outlet 16. The leads 14 are formed in a curved shape that connects the leads 14 while correcting them.

The entrance 15 is formed wide on the distal end side so that the lead 14 can be introduced even when the lead is new, in which the lead is spread in a U-shape, or when the lead is bent for some reason. After that, it is gradually narrowed down and connected to the lead correcting section 11. Lead straightening unit 11
Has a groove width necessary for straightening and aligning the expanded or deformed leads 14 in a row while guiding the lead 14 passing therethrough, and leads to an outlet 16 at the end of the groove.

The lead correction sections 11, 11 arranged side by side
Means that both entrances 15, 15 have an inner space a smaller than the space between both exits 16, 16 and the route on the way is
It has an inner space b wider than the space of 6, 16 (FIG. 1).
reference).

That is, the lead 14 is bent inward,
The spacing between the 14 rows of leads on both sides is, for example, the lead straightening unit 1
It is possible to cope with a case where the interval between the rows of leads 14 that have exited the outlet 16 after being corrected by 1 is narrower. In addition, the lead 14 is once widened and then narrowed by tracing a path along the curve from the entrance 15 (the inner space a) to the outlet 16 via the intermediate route (the inner space b), so that the lead 14 has a desired column width. (The interval between the two outlets 16, 16).

This lead straightening tool 10 is used while waiting in one hand or fixed on a table or the like. With the DIP type IC 12 held in the other hand, each lead 14 is led from each entrance 15 to each lead straightening section 11. (See arrow in FIG. 1), pass through each lead straightening unit 11 and exit from each outlet 16. As a result,
Each lead 14 is aligned with the lead straightening unit 1 along the arrangement direction.
In this case, each lead 14 is guided by the lead straightening unit 11 and aligned in a straight line.

Therefore, the IC is connected via a plurality of leads 14.
When mounting the IC package 13 to or from a socket (not shown) as needed, the plurality of leads 14 can be mounted to the IC socket by using the lead correction tool 10. It is possible to form a straight line-aligned state with a line width (the interval between both outlets 16, 16).

That is, for example, a rewritable PRO
M (programmable read only)
In memory, the written contents are corrected and reinserted into the socket, and the socket is inserted and removed several times for mounting and disengaging from the socket. At this time, the lead may be bent.

When the lead is bent, the lead must be straightened using, for example, pliers or the like.
Could not be mounted in the socket, but by using this lead straightening tool 10, the lead can be straightened easily and it becomes easy to insert it into the socket.

As described above, according to the present invention, by passing the leads 14 through the lead correcting section 11, the leads 14 are guided in a fixed direction, and the arrangement of the leads 14 is corrected and aligned in a desired row width. You. Therefore, even when the leads 14 are spread in a C-shape or when the leads 14 are bent for some reason, for example, the leads 14 are arranged in a line without pressing the leads 14 on a flat surface.
That is, the lead 14 can be properly corrected so as to enter the IC socket.

It should be noted that in the above-described embodiment, the lead arrangement to be corrected by the lead correction tool 10 is a DI
The plurality of leads are not limited to the P-type IC 12
What is necessary is just to be arrange | positioned downward with respect to the package.

[0022]

As described above, according to the present invention, when the plurality of leads arranged downward with respect to the IC package are moved along the arrangement direction by the correction groove, the plurality of leads are guided. The leads are aligned in a straight line so that the lead can be easily straightened appropriately.
