Definitions

• the present invention relates to a potentiometer that includes a resistor substrate and a sliding brush mounting plate on which a sliding brush having a contact pressed against the resistor substrate is mounted to obtain an arbitrary electric output.
• FIG. 1 is a case where the rotation shaft 2 of the potentiometer is set and stopped at the mechanical initial position, and the rotation of the fixed position of the main body 3 is adjusted to match the electrical output.
• 1 is ⁇ unit, 4 ⁇ 4 a main body fixing screws, 5 ⁇ 5 a is long hole for screws, arrows are tone ⁇ direction.
• Examples of the second view is fixed to the main body 3 of Boten tio menu over data, after 0 setscrew 6 is a case of adjusting the rotational drive 2 times 3 ⁇ 4 adjustment is for the shaft 2 mouth Tsukusuru .
• a resistive substrate and a sliding brush in which contacts are pressed against the resistor and the collector on the resistive substrate are attached.
• a sliding brush mounting plate is provided, and one of the resistor substrate and the automatic brush mounting plate has a means for independently moving its position from the outside.
• the relative positional relationship between the contact point of the moving brush mounting plate and the contact point can be adjusted externally.
• the main body is fixed, and the rotary drive tab or linear opening lever is moved to any position l O. Even in a state where the power is stopped, the initial electrical output of the potentiometer can be adjusted to a predetermined value externally in a short time, easily and accurately. It is intended to provide the data.

• Figure 4 shows a slide. It is a top view in the state where the moving brush etc. were removed. 5 Center the rotation center on the rotating plate 7 with the tooth shape 7a Eventually, the resistor substrate S is fixed, and the surface of the resistor substrate S is provided with a horseshoe-shaped resistor ⁇ 9 and a collector 1 o. in the sliding friction plate 1 1 and held by pressure contact, the teeth 7 a is connected to the fine adjustment gear 1 2, attachment fitted with the rotary plate Ryo Ke - to scan 1 3 holding the Hasatsuki 1 2 ing.
• Figure 5 shows a conceptual diagram of a configuration of rotating the sixth by the fact rotate the fine adjustment teeth grass 1 2 in FIG] resistor substrate S is an exploded explanatory view of the rotation regulating portion, Fig. 6 is the S ⁇ view of the same part after ⁇
• the part of the end face of the rotating plate 7 "A and 3 ⁇ 4 the urchin g type 7 a by the above-described tear] 5, is fine adjustment ⁇ 1 2 and ⁇ because, in figure Gear 1 2
• the rotating plate rotates around the portion C in the direction b in the figure, to which the resistor substrate 8 is attached. Therefore, by turning the fine adjustment bacteria 2 in the a direction fc, the resistor substrate 8 can be turned in the b direction around the C portion.
• the problem is that once the electrical output is adjusted to a predetermined value, the adjustment position does not fluctuate due to vibration or impact, and long-term stable convenience can be realized.
• the point is that you have to go long.
• the rotating plate is finely adjusted by the gear 15 for fine adjustment.]
• the ⁇ and D parts slide on the mounting case 13 by friction, and after adjustment, the friction force Due to D movement is restricted.
• the degree of pressure contact of the sliding friction plate 11 is set to an appropriate value, fine movement of the rotating plate 7 due to vibration etc. after adjustment will be with everyone! ), Allows long-term stable use even if left as it is after adjustment.
• the relative position adjustment between the resistance substrate S and the contact 15 of the slider 16 is not limited to the means for moving the resistance substrate S as in the above example. ⁇ ⁇ Needless to say, it can be realized by moving the brush mounting plate 4. That is, fixing a Suridosuriko mounting plate 1 4 5 At the same times ⁇ heart on the times ⁇ that provided teeth Ryo a, to 3 ⁇ 4 forming a fine adjustment S wheel 1 2 This lightning type 7 a , this Hold the teeth 1 and 2 in the mounting case 13 and fine-tune the above ⁇ Arrange the gear 12 so that it can be rotated from the outside, and rotate the sliding brush 1 e from the outside through the teeth 12 What is necessary is just to have an adjustable configuration. In this case, it is obvious that the resistor substrate s is held on the mounting case 13 .
• the rotary potentiometer has been described, but the present invention is also applicable to a linear I dynamic potentiometer.
• a resistor base plate or a sliding brush mounting plate is fixed on a movable plate that is held movably in a straight line on the mounting case and has a tooth profile on the end face, and the fine adjustment gear is connected to the tooth profile, Hold the fine adjustment teeth of the bracket in the mounting case, arrange this gear so that it can be rotated from the outside, and adjust the resistance substrate or the sliding brush mounting plate from outside through this tooth. Any configuration may be used.
• the sliding thick plate may be pressed against and held by the resistor substrate or the slider mounting plate so that the braking force acts in the moving direction of the slider mounting plate.
• the potentiometer of the present invention even when the main body is fixed and the rotary drive shaft or the linear motion lever is stopped so as not to move to an arbitrary position, the potentiometer can be used.
• the initial electric output of the monitor can be easily and accurately set to a predetermined value from the outside in a short time.
