Description

[Detailed description of the invention] This invention focuses on the structure of the slider installation. More specifically, in small electric components such as small sliding variable resistors, the slider is mounted on a micro slider receiver. Regarding the structure for installing the slider, the purpose is to provide a structure that is easy to install and does not cause the fragile slider to be deformed during installation. be.

Conventionally, in electrical components such as variable resistors, in order to attach a slider to a slider receiver, a plurality of small protrusions are provided on the lower surface of the slider receiver, and the mounting surface of the slider is provided with a plurality of small protrusions. It was common practice to provide small holes corresponding to the small protrusions, fit the small protrusions of the slider holder into the small holes of the slider, and then heat-squeeze them for attachment.

However, with the recent miniaturization of electronic components, sliders and slider receivers have become miniaturized, making tightening work in narrow spaces extremely difficult. There was a drawback that the mover was plastically deformed.

For example, even though the mounting surface dimensions of the slider of the slider receiver are as small as 5 mm x 7 mm as in the embodiment of the present application shown in the second figure,
When installing two sliders in parallel and using this for a dual-type variable resistor, the width of one slider is 3 mm, and the conventional mounting method does not allow sliding. It is technically almost impossible to securely fix the slider to the slider receiver.

The present invention has been developed in view of the above points, and will be described in detail below with reference to illustrated embodiments.

In Fig. 1, 1 is a substantially box-shaped sliding handle made of insulating synthetic resin, 2 is a lever integrally formed on the top surface of this handle, and 3 is a sliding handle made of insulating synthetic resin.
Reference numeral 4 indicates a hole formed on the side surface for loading a click spring and a ball, 4 indicates an attachment section on the lower surface of the slider receiver 1, and 5 indicates a slider attached to this attachment section by a method described later.

This slider receiver 1 is moved by a lever 2 orthogonally in the direction of the arrow in FIG. 1 over an insulating substrate on which a band-shaped resistor of a slide type variable resistor (not shown) is formed.

FIG. 2 shows a state in which the slider holder 1 is mounted without the vermilion slider 5 attached to the section 4. 5mmX7mm
This minute attachment is achieved by arranging a pair of minute sliders 5 on the part 4 in parallel.

As is clear from the figure, for installation, two second slots 4a are provided at one end in the sliding direction of the part 4, and two pairs of first slots 4b are provided at the other end. It is formed.

The two first slot holes 4b and one second slot hole 4a form a hole for mounting one slider 5, and the groove width d2 of the second slot hole 4a is The groove width d1 of the first slot 4b is set larger than the groove width d1.

Further, the lengths of the first slot 4b and the second slot 4a are approximately equal to the widths of the first locking piece and the second locking piece of the slider, which will be described later. Moreover, slots 4a, 4
In both cases, the bottom portions of b are closed.

In addition, in the figure, 4C is a slit for convenience in molding.

FIG. 3 shows a slider 5 formed by bending a single sheet of highly conductive metal thin plate into a substantially U-shape. A pair of first locking pieces are formed by bending, and 5C is a protrusion formed by embossing provided on the side of this locking piece.

5e is a second locking piece formed by cutting and raising a notch hole 5d at the other end of the flat plate part 5a;
A plurality of elastic contact pieces extend downward from a bending portion 5f via a bending portion 5f, and a contact protrusion portion 5h is formed at the tip of each of the contact pieces 5g.

The first and second locking pieces 5b and 5e are connected to the first and second slots 4b and 4a provided in the mounting portion 4 of the slider receiver 1.
The locking piece 5e loosely fits into the slot 4a, and the locking piece 5b fits into the slot 4b.

As is generally clear from the above configuration, in order to attach the slider 5 to the slider receiver 1, first the second locking piece 5e of the slider 5 is attached.
into the second slot 4a of the slider receiver 1, and then insert the
What is necessary is to fit the locking piece 5b into the first slot 4b.

At this time, since the first locking piece 5b is provided with the protrusion 5C, the locking piece 5b is press-fitted into the first slot 4b, while the second slot 4a is is the second locking piece 5e
Since it is set to be relatively larger than the plate thickness of the slider, it is possible to not only absorb slight dimensional errors during installation, but also prevent deformation of the slider due to forced assembly during installation. .

Then, when the slider 5 is assembled into the variable resistor with the slider 5 attached to the slider receiver 1, the contact piece 5g of the slider 5 comes into elastic contact with the insulating substrate, so the slider 5 is attached to the slider holder 1. The slider 5 does not come out downward from the receiver, and the slider 5 does not displace in the lateral direction or the sliding direction, and the slider 5 is securely attached to the slider receiver 1 without using any conventional means. It will be in the attached state.

In the above embodiment, two sliders 5 are attached to the slider receiver 1, but the number of sliders that can be attached is not limited to this. The number and shape are not limited to the examples.

As detailed above, according to the present invention, the slider can be installed by simply fitting, which not only makes it easy to assemble, but also allows for some dimensional errors in the slider and slider holder. However, there is no risk of deformation of the slider due to forced installation, making it ideal for attaching minute sliders.
