Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to electronic components mounted on printed circuit boards, and is a method for attaching and detaching electronic components that can be performed in an integrated manner, including bending lead wires, setting the mounting pitch, and attaching and detaching electronic components. Regarding the jig.

(Summary of the invention) The jig for attaching and detaching electronic components of the present invention has an L-shaped protrusion at one end and is used to remove failed electronic components. Bend the wire to the mounting pitch, insert the electronic component with the bent lead wire into the hole corresponding to the mounting pitch approximately in the center, correct the mounting pitch of the lead wire, check the dimensions, and insert the electronic component. It can be inserted into the recess on the opposite side of the jig and the entire process of attaching it to the printed circuit board can be easily performed.

(Prior Art) Conventionally, when replacing a failed electronic component, attachment and detachment were carried out using tweezers, a screwdriver, or the like. In particular, as devices become lighter, thinner, shorter, and smaller, parts are mounted closely on printed circuit boards, making it difficult to attach and detach them.

(Problem that the invention aims to solve) However, when attaching and detaching using tweezers or a screwdriver, there are problems such as short circuits, disconnections, and damage to other components, especially since the printed circuit board is crowded with components. Ta. In addition, electronic parts that are difficult to replace require the removal and replacement of other parts, which has the disadvantage of requiring a considerable amount of work time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a jig for attaching and detaching electronic components that eliminates the above-mentioned problems and facilitates consistent operations from bending lead wires to replacing parts.

(Means for Solving the Problems) In order to solve the above problems, the present invention forms a recess at one end of the main body formed in a plate shape, and has L-shaped tips on both sides of the recess. A protrusion is provided at the other end,
A recess is provided in the center, a groove is provided in the center in the plate thickness direction on both sides of the recess, a protrusion is formed approximately in the center of the recess, and a claw is provided at the tip of the protrusion.

(Function) A recess 2 is formed in one end of the main body 1 formed in a plate shape, and a lead wire is provided in the recess 2 on the side where the L-shaped protrusion 3 is provided at the tip of both sides of the recess 2. Electronic components 10 such as resistance fuses and capacitors are placed, bent along the sides of the main body 1 formed in a plate shape, and inserted into two holes 4 provided in the plane of the main body 1.
The mounting pitch of the lead wire 11 is corrected and the dimensions are confirmed. The L-shaped protrusion 3 is attached to the printed circuit board 12 and is used to remove the failed electronic component 10, and hooks the lead wire 11 thereon.
It has a function of removing the electronic component 10 by pulling it upward.

The electronic component 10 with the lead wire 11 portion bent,
Place it in the recess 5 on the opposite side, insert the lead wire 11 into the groove 6, support the main body 9 of the electronic component 10 with the claws 8 of the projection 7, and press fit it into the socket 13 provided on the printed circuit board 12. Electronic component 10 is mounted.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a perspective view of a jig for attaching and detaching electronic components according to the present invention, Fig. 2 is a perspective view showing bending of lead wires using the jig, and Fig. 3 is a perspective view of correcting the mounting pitch of lead wires using the jig. , FIG. 4 is a perspective view showing the work of mounting the electronic component on the printed circuit board using the same jig, and FIG. 5 is a perspective view showing the work of removing the electronic component.

A recess 2 is provided at one end of a plate-like, substantially rectangular main body 1, and protrusions 3 are formed from both sides of the recess 2, the tips of which are bent into an L-shape at right angles to the plane of the plate. Two holes 4 are provided approximately at the center of the approximately rectangular body 1, and the pitches of the holes 4 are set to be approximately the same when the lead wire 11 is bent, depending on the width of the tip of the body 1. The holes 4 may be plural,
The pitch of the hole 4 and the width of the tip of the main body 1 are set to be approximately the same in order to accommodate bending by both sides of the jig.

At the other end of the main body 1, a recess 5 is formed approximately in the center,
Grooves 6 are provided in the thickness direction on both sides of the plate. Furthermore, a projecting piece 7 is provided on one side of the substantially center of the recess 5, and a claw piece 8 is formed at the tip of the projecting piece 7. This projecting piece 7 has elasticity, and is used to support the electronic component 10 placed in the recess 5 by the claw piece 8.

Therefore, it is preferable that the electronic component 10 be easily removed when it is press-fitted into the socket 13.

As described above, the present invention is a jig for attaching and detaching electronic components that can easily perform consistent operations such as bending lead wires, correcting mounting pitches, checking dimensions, and attaching and detaching.

(Effect of the invention) As described above, according to the present invention, the main body 1 formed in a plate shape
A recess 2 is formed at one end, L-shaped protrusions 3 are provided at both ends of the recess 2, and a recess 5 is provided at the center of the opposite end, and a recess 5 is formed at the center of both sides in the thickness direction. Groove 6
At the same time, a projecting piece 7 is formed approximately in the center of the recess 5.
, and the claw piece 8 is formed at the tip of the protruding piece 7. (1) The entire process of bending the lead wire, correcting the mounting pitch of the lead wire, checking dimensions, and attaching/detaching electronic parts It has the characteristic of making it easy to carry out tasks.

(2) Electronic components mounted closely on a printed circuit board can be easily replaced without removing other components, which has the effect of shortening work time.

(3) Even when replacing electronic components that are densely mounted on a printed circuit board, no skill is required and short circuits and
It has the feature that it can be easily worked on without affecting other parts such as disconnection or damage.

(4) It does not require many tools to replace parts, which simplifies tool management.
