Description
Technical field
What the present invention relates to is a kind of potentiometer, and especially a kind of overall plastic envelope potentiometer belongs to a kind of electronic devices and components.
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, and 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 is high, the defective that waterproof, humidity resistance are generally lower.
Summary of the invention
The objective of the invention 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 objective of the invention is to accomplish through following technical scheme; 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, in draw-in groove, is placed with O type rubber ring, and this O type rubber ring closely contacts with rotating shaft, the draw-in groove gone up on the coupling band respectively; The bottom of said rotating shaft is connected with a contact spring, and this contact spring is 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 present invention 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 practiced thrift 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.
To combine accompanying drawing that the present invention is done detailed introduction below: like accompanying drawing 1, shown in 2; The present invention 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, in draw-in groove 22, are placed with O type rubber ring 3, and 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 said 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 present invention is the metalwork except weld tabs 6 with resistor disc 7, and other are, and plastic material processes, and greatly reduce production cost like this, and performance increases substantially also.
Like accompanying drawing 3,4,5, shown in 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 projection in this rotating shaft 11 corresponding coupling band 2 inwalls of going up, 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 that join on the inwall, prevents excessive rotation.
Described pedestal 5 inside center are provided with a circular hole 51, and this circular hole 51 is spacing with the end of rotating shaft 1 and is connected.
Other a kind of structure of the present invention can be: when the user does not have special demands waterproof, protection against the tide, anti-dust performance to this product; Can be designed to: get rid of in draw-in groove 22, being placed with O type rubber ring 3; Potentiometer has just weakened waterproof, protection against the tide, the dustproof performance of starving like this; But original other performances also still keep, and purpose is more to have reduced production cost.
The present invention will go up coupling band and pedestal adopts moulding ultrasonic wave compression technology to be the complete plastic sealed structure that is connected as a single entity; Not only have stable performance, high voltage withstanding effective, characteristics such as sealing property is high, cost is low, 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.
