[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure for attaching a slider to a slider receiver used in rotary switches, variable resistors, etc.

[Conventional technology]

FIG. 10 is a sectional view of a main part of a conventional variable resistor.

Conventionally, in order to attach a slider 1 made of an elastic metal plate to a slider receiver 2 made of an insulating material, a mounting protrusion 3 is integrally provided on the slider receiver 2, and the slider is attached to the protrusion 3. After inserting it through the mounting hole 4 of No. 1, the tip was caulked.

[Problem that the invention attempts to solve]

However, when the slider receiver 2 is incorporated into a variable resistor, the sliding contact piece 1a of the slider 1 is in elastic contact with the resistor 6 on the resistor board 5, so the slider 1 moves in the direction of the arrow. Although the slider 1 receives a reaction force in the direction B, since the end 1b of the slider 1 is free, the stress concentrates on the protrusion 3, which causes the protrusion 3 to break and the slider 1 to separate from the slider holder 2. There was a drawback that it was difficult to use.

The present invention aims to solve the above-mentioned conventional drawbacks, and the purpose of the present invention is to provide a mounting structure for a slider that can be securely attached without worrying about it coming off during use. It is something.

[Means for solving problems]

In order to achieve the above object, the present invention provides a cut groove at the end of the slider and an elastic rising piece in the vicinity of the cut groove. A rising arm having an engageable hook portion is provided, a projection is provided on one of the slider and the slider receiver, a hole into which the projection fits is provided on the other, and a rising piece of the slider is provided. A recess is formed in the slider receiving portion corresponding to the vicinity of the bent portion.

[Effect]

The embodiment of the present invention has the structure as described above, and according to the present invention, by fitting the protrusion provided on either one of the slider and the slider holder into the hole provided on the other. The slider is prevented from moving in a direction horizontal to the mounting surface of the slider receiver, and the upper end of the rising piece of the slider is not engaged with the hook portion of the rising arm provided on the slider receiver. Therefore, the slider is prevented from coming off in a direction perpendicular to the mounting surface of the slider receiver.

In addition, since the rising piece at the end of the slider engages with the hook part of the rising arm of the slider holder, even if the slider receives a reaction force in the opposite direction to the resistance surface, the slider Stress is not concentrated on the caulked protrusion of the receiver, and therefore the protrusion is not damaged.

Furthermore, when the slider is attached to the slider holder, after the rising piece of the slider falls into the recess of the slider holder, it returns to its original state due to its own elasticity, and the slider holder returns to its original state. Since it engages with the hook provided on the side, reliable engagement between the two is achieved.

Next, using FIG. 8, move the slider 18 to the slider receiver 11.
We will explain the installation process.

First, as shown in FIG. 8A, the hole 20 of the slider 18 is
is opposed to the protrusion 12 of the slider receiver 11, and the bent portion 19a of the rising piece 19 of the slider 18 is placed opposite the protrusion 12 of the slider receiver 11.
1, the slider 18 is pressed in the direction of the slider receiver 11 (in the direction of the arrow) using a jig.

Then, as shown in FIG.
The rising arm 13 of the slider receiver 11 comes into contact with the hook portion 14, and eventually the rising piece 1 of the slider 18 comes into contact with the hook portion 14.
The bridging piece 19b of No. 9 is elastically deformed in the c direction as shown in FIG. When the slider 18 is further pressed downward, the bridging piece 19b of the slider 18 disengages from the hook portion 14 of the slider receiver 11, and the bent portion 19a of the rising piece 19 of the slider 11 disengages. The area near the slider holder 11 fits into the recess 17 of the slider receiver 11 along the tapered surface as shown by the dotted line.

In this state, if the pressure on the slider 18 is stopped, the bridging piece 19b of the rising piece 19 of the slider 18 returns to its original state due to its own elasticity, as shown in FIG. 19 and the hook portion 14 of the rising arm 13 of the slider receiver 11 engage with each other.

After that, the tip of one of the protrusions 12a of the protrusions 12 is caulked.

According to the embodiment of the present invention as described above, by fitting the hole 20 of the slider 18 into the protrusion 12 of the slider receiver 11, the slider 18 can be attached to the mounting surface of the slider receiver 11. Movement in the horizontal direction is prevented, and the upper end of the rising piece 19 of the slider 18 engages with the hook portion 14 provided at the tip of the rising arm 13 provided on the slider receiver 11. The slider 18 is prevented from coming off in a direction perpendicular to the mounting surface of the slider receiver 11.

Further, since the upper end of the rising piece 19 of the slider 18 is engaged with the hook portion 14 of the rising arm 13 of the slider receiver 11, when the slider receiver 11 is assembled into the variable resistor, Even if the slider 18 receives a reaction force in the direction opposite to the resistance surface, stress will not be concentrated on the caulked protrusion 12a of the slider receiver 11, and therefore the protrusion 12a will not be damaged. do not have.

For the reasons mentioned above, the slider 18 is securely fixed to the slider receiver 11.

Furthermore, when the slider 18 is attached to the slider receiver 11, the vicinity of the bent portion 19a of the slider 18 once falls into the recess 17 of the slider receiver 11, and then returns to its original state due to its own elasticity. After returning to the state, the upper end of the rising piece 19 engages with the hook portion 14 at the tip of the rising arm 13 provided on the slider receiver 11, so that reliable engagement between the two is achieved.

Further, since the slider 18 has a cut groove 18a at the end and a raised piece 19 is bent, when the raised piece 19 comes into contact with the hook part 14, the bridging piece 19b is formed as shown in FIG. is easily elastically deformed in the c direction, and therefore does not require a large force during installation and is easy to install.

Moreover, since the upright piece 19 has the bent portion 19a bent to form an R portion, a so-called rib effect works, and deformation of the upright piece 19 in the vertical direction can be prevented.

Note that the slider 18 is provided with a projection, and the slider receiver 11 is
A hole into which the protrusion fits may be provided, and the recess 17 of the slider receiver 11 does not necessarily have to be tapered.

Further, in the above embodiment, the rising arm 13 and the hook portion 14 are described as having rigidity, but
It may have elasticity.

[Effect of idea]

According to the present invention, by fitting the protrusion provided on one of the slider and the slider receiver into the hole provided on the other, the slider is horizontal to the mounting surface of the slider receiver. Furthermore, since the upper end of the rising piece of the slider engages with the hook portion of the rising arm provided on the slider receiver, the mounting surface of the slider receiver of the slider is prevented from moving in the opposite direction. Dislodgement in a direction perpendicular to is prevented, so that the slider is securely fixed to the slider receiver.

In addition, when the slider is attached to the slider receiver, after the slider falls into the recess of the slider receiver, it returns to its original state due to its own elasticity, and the hook attached to the slider receiver returns to its original state. Since it engages with the part, it is possible to reliably engage the two.

Furthermore, since the slider can be attached by pressing the slider from above, production using an automatic machine is easy.
