Such as Fig. 1, Fig. 2, it has demonstrated the concrete structure of the potentiometer of light dimming electric motor, the upper end of potentiometer 1, lower end, front end have respectively slit 201,202,203, when producing light dimming electric motor, foreign matter is very easy to enter in the potentiometer 1 by these slits 201,202,203, potentiometer 1 was lost efficacy, and then cause whole light dimming electric motor to lose efficacy.The main mode of pasting paster and labor cleaning that adopts is removed foreign matter at present, not only efficient is low, inconvenient operation, and also effect is not good yet, can't guarantee the thorough removing of foreign matter 100% totally, many feedbacks that cause light dimming electric motor to lose efficacy because of foreign matter have been arranged on the market.
Therefore, if can not prevent that in the production process of light dimming electric motor foreign matter from entering in the potentiometer, the stability of potentiometer performance will can not be guaranteed, and cause potentiometer and light dimming electric motor to be easy to occur unusual.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of sheath for the light dimming electric motor potentiometer, it is simple in structure, easy to operate, effect is good, can prevent that foreign matter from entering in the potentiometer, guarantee the stability of potentiometer performance, be conducive to reduce the unusual of potentiometer and light dimming electric motor.
The utility model adopts following technical scheme for achieving the above object:
A kind of sheath for the light dimming electric motor potentiometer, comprise by an overhead gage, a lower baffle plate, a backboard, a right baffle-plate and a right baffle plate and enclose the housing that forms, housing has one to the suitable containing cavity of open front and shape and potentiometer, and the internal face of right baffle-plate is provided with one and is used for potentiometer is fixed on left salient point buckle in the containing cavity.
Wherein, for guaranteeing that further fixed potential device, the internal face of described right baffle plate are provided with one for the right salient point buckle that potentiometer is fixed in the containing cavity.
Wherein, described left salient point buckle and right salient point buckle be over against distribution, over against two salient point buckle interference engagement push down potentiometer, can locate potentiometer better.
Wherein, described right baffle-plate and right baffle plate be provided with over against breach.
A kind of sheath that is used for the light dimming electric motor potentiometer for car light that the utility model is set forth, its beneficial effect is: when producing light dimming electric motor, potentiometer is placed the containing cavity of this sheath, utilize overhead gage, lower baffle plate, backboard that the slit on the potentiometer is covered in, prevent that foreign matter from entering potentiometer inside by the slit, guaranteed the stability of potentiometer performance, be conducive to reduce the unusual of potentiometer and light dimming electric motor, and simple in structure, easy to operate, effect is splendid, in addition, this sheath is reusable, and economy is good.

Embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Please refer to Fig. 1 to shown in Figure 4, it has demonstrated the concrete structure of the utility model preferred embodiment, a kind of sheath for the light dimming electric motor potentiometer, comprise by an overhead gage 11, a lower baffle plate 12, a backboard 13, a right baffle-plate 14 and a right baffle plate 15 and enclose the housing 10 that forms, housing 10 has one to the suitable containing cavity 16 of open front and shape and potentiometer 1, and the internal face of right baffle-plate 14 is provided with one and is used for potentiometer 1 is fixed on left salient point buckle 141 in the containing cavity 16.
For guaranteeing that further fixed potential device 1, the internal face of described right baffle plate 15 are provided with one for the right salient point buckle 151 that potentiometer 1 is fixed in the containing cavity 16.
And described left salient point buckle 141 and right salient point buckle 151 be over against distribution, like this, over against two salient point buckle interference engagement push down potentiometer 1, can be better to potentiometer 1 location.
For ease of sheath is taken off from potentiometer 1, described right baffle-plate 14 and right baffle plate 15 be provided with over against breach 142,152.
Operation principle of the present utility model is as follows:
When producing light dimming electric motor, before the PCBA of light dimming electric motor crosses wave-soldering, the sliding handle 3 of potentiometer 1 front end is faced toward the opening insertion of containing cavity 16, make potentiometer 1 place containing cavity 16, left salient point buckle 141 and the right salient point buckle 151 of sheath fastens the rear end face of potentiometer 1 and potentiometer 1 fixed, prevent that potentiometer 1 from dropping from containing cavity 16, at this moment, overhead gage 11 covers in the slit 201 of potentiometer 1 upper end, prevent that foreign matter from entering potentiometer 1 inside from the slit 201 of potentiometer 1 upper end, lower baffle plate 12 covers in the slit 202 of potentiometer 1 lower end, prevent that foreign matter from entering potentiometer 1 inside from the slit 202 of potentiometer 1 lower end, backboard 13 covers in the slit 203 of potentiometer 1 front end, prevent that foreign matter from entering potentiometer 1 inside from the slit 203 of potentiometer 1 front end, cross in wave-soldering and the follow-up processing procedure at PCBA like this, avoided foreign matter to enter in the potentiometer 1, after being used to complete, strut left salient point buckle 141 and right salient point buckle 151, releasing is fixing to potentiometer 1, can pass through breach 142 by a hand this moment, 152 pinch potentiometer 1, the another hand takes off sheath gently, for reusing.
Adopt this sheath, guaranteed the stability of potentiometer 1 performance, be conducive to reduce the unusual of potentiometer 1 and light dimming electric motor, and simple in structure, easy to operate, effect is splendid, and in addition, this sheath is reusable, and economy is good.
