Description

[Detailed explanation of the invention] The present invention is a sliding type resistor, more specifically, a large number of resistors are arranged in one housing, and a large number of resistors are installed in one slider holder. Regarding slide-type variable resistors that are compatible with sliders and allow the resistance values of each of these resistors to be varied in conjunction with a single lever, we offer products that are particularly easy to assemble and have high operational reliability. The purpose is to provide.

-, .': 1 The present invention will be explained in detail below with reference to a first embodiment shown in the drawings.

FIG. 1 is an external perspective view of a variable resistor. In the figure, 1 is a metal frame, and the frame 1 includes an upper surface portion 1b and an upper surface portion 1bJ' that hangs down from the sides of both ends. There are two pairs of narrow legs 1a, and above and below these legs 1a there are wide mounting parts 1a' that hold the insulating substrates 2, 3'.
, 1a'' are formed, and the whole has an eye shape.

In the longitudinal direction of the upper surface part 1b of the frame 1, there is a slider and a bridge made of stone.
A long groove 1C is formed to guide the attached lever.

Note that 1d is a mounting hole.

The insulating substrates are mounted facing each other by the protrusions 1e and 1e of the insulating substrates 2 and 3. For example, on the opposing surfaces of the insulating substrates 2 and 3, A plurality of strip-shaped resistor elements 4 as shown and a plurality of conductors 1 corresponding to the edges □

In addition, 14a and 13a are the resistors 1 of fL, respectively.

As shown in Figure 3, bulges 6a and 6d are formed on the upper and lower sides of this slider holder, respectively, and a narrow flat plate is formed between the upper and lower bulges 6a and 6d. 6:C' is formed, and on both sides of this flat plate part 6C, a plurality of jm#F- are formed in sliding contact with the resistor 14 and the conductor 13 formed on the opposing surfaces of the insulating substrates 2 and 3, respectively. , 12 are connected by appropriate means.

Above, a lever 7 is protruded from the top surface of the Q child receiver 6.
This lever 7 further includes a square groove 1 provided in the upper surface portion 1b of the frame body 1.
Projects outside C.

It looks like this.

In addition, a hole 6e is provided in the center of the upper bulge 6a of the slider receiver 6.
is formed, and a guide bar 8 is passed through this to slidably hold the slider receiver 6.

Both ends of the guide bar 8 are fixed to mounting portions 1 a' and 1 a' above the leg portion 1 a with nuts 9.

On the other hand, as shown in FIG. 4, the protruding portion 6d on the lower side of the slider receiver 6 has its chevron-shaped ends 6d-1 and 6d-1 in contact with the opposing wall surfaces of the pair of insulating substrates 2 and 3. are in contact with each other.

Therefore, the slider receiver 6 moves in the longitudinal direction of the housing along the upper guide bar 8 by the operation of the lever 7.
At this time, the structure is such that the lower bulge 6d prevents lateral wobbling during movement.

Note that the end portion 6d-1 of the bulging portion 6d may be shaped to have elastic force as necessary.

The above-mentioned 4. The figure is a longitudinal sectional view of the variable resistor of the present invention after the assembly ρ of FIG. 1 has been completed, taken along the line A-A'. The upper bulge 6a of 6 is connected to the base plate 2.3 and the frame leg 1a.
The slider 1z is placed on the opposite surface of the narrow flat plate portion 6C between the upper and lower bulges 6a and 6d, so that the slider 1z is located outside the casing configured by Care has been taken to make the width as small as possible, and
The vertically long slider receiver 6 is guided above by the guide bar 8 and below by the bulge 6d, so sliding is stable without only horizontal wobbling, and the substrates 2, 3
The large number of sliders 12 sandwiched between the slider receiver 6 and the slider receiver 6 apply appropriate sliding pressure to the slider receiver 6 due to their elasticity.

As shown above, according to the present invention, the bulge on the upper side of the slider receiver, which tends to be large due to the necessity of inserting the guide bar, is located outside the space where both insulating substrates face each other. The distance between the two insulating substrates can be reduced, and the entire variable resistor can be made as flat and compact as possible.

In addition, since the Mi slider receiver is guided at the top and bottom, it has extremely good sliding stability, and overall, a large number of sliding resistance parts can be housed in a relatively compact housing, and the structure is This has the advantage of providing a multiple type variable resistor that is easy to assemble.
