Below, in order each member that constitutes this slide type variable resistor is elaborated.

Framework 1 is to be forced the dun toro shape of the lower aperture that (Off オ-シ Application グ) form by metallic plate, the left and right sides of upper plate 1a is provided with the side plate 1b that the pair of straight angular distortion forms, and side plate 1b upward has altogether in the left and right sides to extend in the mode outstanding from its lower ends downward side and is provided with 5 installation feet 2.Can find out significantly from Fig. 4-Fig. 9, be positioned between a pair of installation foot 2 on the side plate 1b of right side (control lever 8a gives prominence to side) and be provided with the rectangular indentation 3 that the lower end is opened, the mid portion of this a pair of installation foot 2 extends respectively Face to face on the side card claw stop 2a vertical with the bearing of trend of aforementioned installation foot 2 is being set as shown in Figure 6.In addition, the 1 couple card claw stop 2a on the aforementioned right side side plate 1b is outstanding to the direction of breach 3, and opposed with breach 3 on above-below direction.In addition, as shown in Figure 3, extend respectively on 1 pair of installation foot 2 on the side plate 1b both sides in the left side opposition side of side (the control lever 8a outstanding) the card claw stop 2a with shape with aforesaid card claw stop 2a is set, and it is at right angles crooked to the lateral direction of its plate face to be positioned at the front end of a pair of installation foot 2 of these both sides.In addition, when framework 1 is in single laying state, if insulation board 4 is loaded on this framework 1, the plate face of aforementioned card claw stop 2a just intersects vertically with the plate face of insulated substrate 4, under actual user mode shown in Figure 4, card claw stop 2a is bent so that the side of the top of card claw stop 2a is moved along the bottom surface of insulation board 4, and the lower end of this card claw stop 2a and framework 1 biside plate 1b is clamped insulation board 4.In addition, it is coniform that card claw stop 2a forms the thickness of root front end is big slightly than substrate is slightly little, in the time of crooked the insulation board non-loosening remained in the gap of card claw stop 2a and biside plate 1b (ガ ).

Insulation board 4 is to be made of insulating material such as phenolic resins or glass epoxy resins, as shown in Figure 1, two ends are equipped with 4 through hole 4a altogether, 2 at every end, arranging the resistance pattern 5 and the current collection figure 6 that form by carbon ink (カ-ボ Application イ Application Network) etc. on the substrate, to fix 4 terminals 7 by the mode that the 7a of tube portion penetrates each through hole 4a at the two ends of this insulation board 4,3 terminals in the terminal 7 are electrically connected with the two ends of resistance pattern 5 and an end of current collection figure 6 respectively.Shown in Fig. 3,4, this insulation board 4 is seized on both sides by the arms the lower end that is fixed on biside plate 1b and constituted above-mentioned body with framework 1 by card claw stop 2a crooked below this insulation board 4.

Driving body 8 is to be formed by insulating properties synthetic resin material, is fixed with slide unit 9 below it, and this slide unit 9 is to be made of the metal plate that has a pair of slide 9a.Be equipped with the control lever 8a that is one with this driving body 8 on the right side of driving body 8, be wholely set the shield 10 of rectangle on the control lever 8a.Shown in Fig. 5,6, resistance pattern 5 and current collection figure 6 that aforementioned driving body 8 forms a pair of slide 9a on the son 9 that slides and insulation board 4 above are slidingly connected, control lever 8a is outstanding to the outside from the breach 3 on the side plate 1b of right side, can be free to slide in the body of above-mentioned framework and insulated substrate 4 compositions, no matter driving body 8 is in any sliding position shield 10 can cover breach 3.

The basic structure of the slide type variable resistor that present embodiment relates to had been described just now, had the following describes operation principle.Vertical view when Figure 10 represents to pack this slide type variable resistor into circuit substrate, Figure 11 is the cutaway view along the 11-11 line of Figure 10.

This slide type variable resistor is generally used in the various electronic instruments, for example as in the small portable electronic devices such as video camera, as Figure 10, shown in Figure 11,2 installation feet 2 on the side plate 1b on framework 1 right side and left side side plate 1b are gone up unbent 1 installation foot 2 embed 3 locating notch 11a places on the circuit substrate 11 that is installed in this equipment respectively, with these installation feet 2 under the correct positioning state by reflowing welding and left side side plate 1b on crooked 2 installation feet 2 and 4 terminals 7 weld, be installed to thus on the surface of this circuit board 11.

In addition, the voltage of regulation is added to the two ends of resistance pattern 5 by terminal 7 from circuit board 11, the operator operates control lever 8a in the direction of arrow A with finger, driving body 8 will and slide in aforementioned body by the biside plate 1b of framework 1 guiding, a pair of self-cleaning contact 9a changes the conduction position of resistance pattern 5 and current collection figure, to from the terminal of connecting with current collection figure 67, send the output signal of the voltage that should conduction position changes, the output signal that obtains is like this reached in the circuit board 11, carry out the various settings and the control of above-mentioned electronic equipment again.

In aforesaid slide type variable resistor, because the installation foot 2 of positioning and fixing body (main body) usefulness is extended to be provided with and forms card claw stop 2a on circuit board 11, therefore can eliminate the interval between the card claw stop 23 and installation foot 29 in the conventional art, and the size that can reduce installation foot 2 and block (arrow A direction) in the orientation of claw stop 2a reaches the purpose of miniaturization.

In addition, make the framework 1 that the control lever 8a of driving body 8 highlights right side side plate 1b breach 3 nearby dispose installation foot 2, therefore the card claw stop 2a by this installation foot 2 is applied to the excessive loads on the insulation board 11 when can sustain operation control lever 8a, prevent to guarantee the contact stabilization of resistance pattern 5 and current collection figure 6 and slide 9a because of distortion or the breakage that excessive loads causes insulation board 11 occurring.

In addition, towards the breach 3 one side-prominent card claw stop 2a that are provided with, therefore can keep out above-mentioned excessive load fully on the installation foot 2 of right side side plate 1b, prevent that fully insulated substrate 11 from deforming and breakage.

In addition, make card claw stop 2a and breach 3 opposed at above-below direction, can be at the inboard configuration card claw stop 2a of control lever 8a moving area (width of breach 3 arrow A directions), the size in the orientation (arrow A direction) of installation foot 2 is reduced.

As shown in Figure 4, inboard at control lever 8a moving area is set at acute angle with each angle of bend that blocks claw stop 2a, the space of occupying of respectively blocking claw stop 2a on the in-plane (arrow B direction) with the insulation board 11 of orientation (arrow A direction) orthogonal of installation foot 2 is reduced, further reach the effect of miniaturization effectively.
