Description

[Detailed description of the invention] This invention relates to a lead wire forming tool.
More specifically, electronic components having an element in the center and lead wires at both ends of the element, such as a resistor,
This relates to tools for forming lead wires of axial type components such as capacitors, diodes, and plated wires.

Conventionally, forming has been performed manually using pliers, long-nose pliers, or the like.

However, electronic components are small, and the lead wires are made of soft metal such as copper wire due to their electrical characteristics, so forming them with pliers is difficult, and the lead wires may be twisted during work.
The song is boring.

Furthermore, when working with these tools, the elements and lead wires are easily damaged, often resulting in defective products.

Furthermore, when electronic components are directly touched during forming, rusting occurs, and good soldering cannot be achieved during soldering.

The present invention aims to eliminate these drawbacks and provide a tool that can perform forming easily and reliably.

An embodiment of the present invention will be explained below based on the drawings.

1 is a tool body, and this tool body 1 is composed of a pair of intersecting frames 2 and 3.

One frame 2 is provided with a handle 4, and a forming part 5 is provided at the tip of the handle 4.

This forming part 5 has a forming width,
The opposing surface 6 is formed as a flat surface, and a recess 7 for accommodating the element A is provided in the flat surface 6. Further, grooves 8, 8, which are slightly larger than the thickness of the lead wire 9, are provided on both sides of the recess 7 so as to communicate with the recess 7. Note that the side surface may be formed into an inclined surface according to the shape of the forming.

The recess 7 is formed in a shape that can accommodate the element A, and may be formed to correspond to the shape of the element A.

Furthermore, grooves 10 communicating with the grooves 8, 8 are provided on both side surfaces of the forming portion 5.

The other frame 3 has the one frame 2
A handle 4 is provided in a substantially symmetrical shape, and a forming part 5a is provided at the tip of the handle 4.
This forming part 5a is the forming part 5.
The opposing surface 6a is formed into a flat surface having the same width as the above-mentioned opposing surface 6 so as to be in close contact with the opposing surface 6 when overlapped.

Further, a pair of leaf springs 11 having a predetermined elasticity are attached to both side surfaces of the forming portion 5a at positions corresponding to the grooves 10 of one of the forming portions 5.

This leaf spring 11 is strong enough to bend the lead wire 9 sufficiently when the facing surfaces 6 and 6a are brought into contact, and is made of SK material, and the tip 12 of this leaf spring 11 is slightly outward. It is spread out in both directions.

13 is a groove provided on the opposing surface 6 and the side surface,
This groove 13 is used when the size of the element A is relatively small.

The pair of frames 2 and 3 are crossed and pivoted at a predetermined position with a rivet 14, and the handles 4 are connected with each other with a screw coil spring 15.
It is movable around 4 as a fulcrum.

Reference numeral 15 denotes a protective cover that protects the element A attached to one forming part 5 or the lead wire 9 in the vicinity of the element, and a curved part 16 is provided at the tip of the protective cover 15 at a position corresponding to the recessed part 7. is formed.

Further, the base end portion 17 of the protective cover 15 is attached to the inside of the forming portion 5 so as to be openable and closable.

FIG. 6 shows a recess 16a for protecting the element A, and recesses 18 for protecting lead wires on both sides of the recess 16a.
This is a protective cover 15 provided with 18.

FIG. 7 shows the cut portion 19 provided inside the forming portions 5, 5a.

This cut portion 19 is connected to one forming portion 5.
A lower blade 20 is provided on the forming portion 5a, and an upper blade 21 is provided on the other forming portion 5a. Lower blade 2
0 is provided with a groove 22 so that the lead wire 9 can be cut into different lengths in order to easily insert it into the hole in the board, and the upper blade 21 is provided with a blade 23 that engages with this groove 22. ing.

When carrying out the present invention, the element A is accommodated in the recess 7, and the lead wire 9 is arranged in the groove 8 by grasping the rear handle 4, as shown in FIGS. 8 and 9. The lead wire 9 is formed with a leaf spring 11.

Further, when the lead wire is provided with a cut portion 19, the lead wire is cut at the cut portion 19 and then formed.

According to the present invention explained above, by simply grasping the rear handle with electronic components placed on one forming part,
Forming parts can be easily created. Therefore, the lead wires will not be twisted or bent during manual forming.

Furthermore, since electronic components can be worked on without touching them directly, subsequent soldering becomes easier.

Furthermore, since the lead wire is bent by a leaf spring having a predetermined strength, the lead wire will not be damaged.

Furthermore, since the electronic components are protected by the protective cover, defective components cannot be produced.

In addition, since it has a cutting part, it is an extremely useful device that allows cutting and forming of the lead wire with one tool.
