Background technology
Potentiometer is the electronic devices and components that a kind of application is quite popularized, can there be bigger difference in its structure according to the difference of making, potentiometer is widely used in all kinds of electronic potentiometers, but some potentiometer is because design is unreasonable, assembling process is comparatively complicated, thereby cause the potentiometer unstable properties, production cost height, the defective that waterproof, humidity resistance are generally lower.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of stable performance, high voltage withstanding effective, sealing property is high, cost is low overall plastic envelope potentiometer are provided.
The purpose of this utility model is finished by following technical solution, it mainly comprises rotating shaft, goes up coupling band, pedestal, described rotating shaft is inserted in the commentaries on classics hole of last coupling band, commentaries on classics hole one side of coupling band is provided with a draw-in groove on this, be placed with O type rubber ring in draw-in groove, this O type rubber ring closely contacts with rotating shaft, the draw-in groove gone up on the coupling band respectively; The bottom of described rotating shaft is connected with a contact spring, and this contact spring is positioned between rotating shaft and pedestal; Described pedestal is provided with three weld tabs, and this weld tabs also links to each other with resistor disc, this resistor disc and weld tabs and this pedestal integrated injection molding; Described pedestal and last coupling band adopt moulding ultrasonic wave compression technology to be complete plastic sealed being connected as a single entity.
As preferably, diameter of axle bottom one side of described rotating shaft is injected with a projection, is injected with a fixture block with the corresponding first line of a couplet sleeve lining of the projection in this rotating shaft, and the draw-in groove outer wall on this fixture block and the last coupling band is connected as a single entity.
As preferably, described base interior center is provided with a circular hole, and this circular hole is spacing with the end of rotating shaft and is connected.
The utility model adopts process procedures such as integral molded plastic, whole assembling, and adopt moulding ultrasonic wave compression technology to come the substituted metal die casting simultaneously, make coupling band and pedestal be integral structure, also increase the performance that O type rubber ring can reach hermetically sealed (waterproof, protection against the tide, dustproof) in rotating shaft and first line of a couplet shaft room; Properties of product and quality of stability have been improved, realized energy-saving and cost-reducing improvement target simultaneously, also saved the use of a large amount of non-environmental protection materials, have stable performance, high voltage withstanding effective, sealing property is high, cost is low, simplify characteristics such as production technology greatly.

Embodiment
Label in the accompanying drawing is respectively: 1, rotating shaft, 2, go up coupling band, 3, O type rubber ring, 4, contact spring, 5, pedestal, 6, weld tabs, 7, resistor disc, 11, projection, 21, change the hole, 22, draw-in groove, 23, fixture block, 51 circular holes.
Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in accompanying drawing 1,2, the utility model mainly comprises rotating shaft 1, goes up coupling band 2, pedestal 5, described rotating shaft 1 is inserted in the commentaries on classics hole 21 of last coupling band 2, commentaries on classics hole 21 1 sides of coupling band are provided with a draw-in groove 22 on this, be placed with O type rubber ring 3 in draw-in groove 22, this O type rubber ring 3 closely contacts with rotating shaft 1, the draw-in groove 22 gone up on the coupling band 2 respectively; The bottom of described rotating shaft 1 is connected with a contact spring 4, and this contact spring 4 is between rotating shaft 1 and pedestal 5; Described pedestal 5 is provided with three weld tabs 6, and this weld tabs 6 also links to each other with resistor disc 7, this resistor disc 7 and weld tabs 6 and these pedestal 5 integrated injection moldings; Described pedestal 5 adopts moulding ultrasonic wave compression technology to be complete plastic sealed being connected as a single entity with last coupling band 2.And the utility model is the metalwork except weld tabs 6 with resistor disc 7, and other are, and plastic material makes, and greatly reduce production cost like this, and performance increases substantially also.
Shown in accompanying drawing 3,4,5,6, diameter of axle bottom one side of described rotating shaft 1 is injected with a projection 11, is injected with a fixture block 23 with corresponding coupling band 2 inwalls of going up of the projection 11 in this rotating shaft, and this fixture block 23 is connected as a single entity with draw-in groove 22 outer walls on the last coupling band.When rotating shaft 1 rotates to certain angle, the projection 11 in this rotating shaft can be caught up with fixture block 23 butts on the connection inwall, prevents excessive rotation.
