Abstract
A rotary potentiometer mainly comprises a resistance card base, a threaded shaft sleeve, a contact spring, a rotating shaft and an encloser, wherein, a resistance card in the resistance card base and a connecting terminal are placed in corresponding card positions, and the resistance card base and the threaded shaft sleeve are formed through one-step injection molding of the injection machine, so as to form an integral resistance card base-shaft sleeve combination; and the encloser capable of wrapping the whole bottom of the resistance card base-shaft sleeve combination and protecting the interior of the resistance card base-shaft sleeve combination is sleeved on the bottom of the resistance card base-shaft sleeve combination, the contact spring is arranged in the inner chamber of the resistance card base-shaft sleeve combination in a corresponding card position, and the rotating shaft is mounted in the central position of the resistance card base-shaft sleeve combination, so as to form the rotary potentiometer. The utility model has the characteristics of stable property, good high-voltage resistant effect, high sealing performance, low cost and the like.
Description
Technical field
The utility model relates to a kind of potentiometer, especially a kind of rotational 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, wherein a rotational potentiometer, its resistor disc pedestal separates injection moulding with threaded sleeve, the structure that is connected with the connecting pin that is the metal cover board of injection moulding threaded sleeve and rear casing.Though this structure has been used for many years, there are the problems of bringing because of the split injection moulding, defective such as, poor sealing performance bad, cost height as unstable properties, high pressure resistant effect always.
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 pressure resistant effective, sealing property is high, cost is low rotational potentiometer are provided.
The purpose of this utility model is finished by following technical solution, it mainly is made up of resistor disc pedestal, threaded sleeve, contact spring, rotating shaft and case, resistor disc and binding post in the described resistor disc pedestal are placed on the corresponding insert position, with injection molding machine with itself and threaded sleeve single injection-molded, thereby form the resistor disc pedestal axle sleeve combination of an integral body.
The bottom of described resistor disc pedestal axle sleeve combination is with a case that the whole bottom of resistor disc pedestal axle sleeve combination can be wrapped, also can protect inside; in this resistor disc pedestal axle sleeve combination inner chamber, on the corresponding insert position contact spring is installed; on the center of resistor disc pedestal axle sleeve combination, a rotating shaft is installed, thereby forms a rotational potentiometer.
The utility model belongs to a kind of improvement to prior art, it passes through the injection molding machine single injection-molded with resistor disc pedestal and threaded sleeve, thereby make resistor disc pedestal and threaded sleeve form integrative-structure, have stable performance, high pressure resistant effective, characteristics such as sealing property is high, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a resistor disc pedestal axle sleeve combining structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction:
The main resistor disc pedestal 1 of the utility model, threaded sleeve 2, contact spring 3, rotating shaft 4 and case 5 are formed, resistor disc 6 in the described resistor disc pedestal 1 is placed on the corresponding insert position with binding post 7, with injection molding machine with itself and threaded sleeve 2 single injection-moldeds, thereby form the resistor disc pedestal axle sleeve combination 8 of an integral body, see shown in the accompanying drawing 2.
The bottom of the resistor disc pedestal axle sleeve combination 8 shown in Fig. 1 is with a case 5 that the whole bottom of resistor disc pedestal axle sleeve combination 8 can be wrapped, also can protect inside; make up at this resistor disc pedestal axle sleeve a contact spring 3 is installed on the corresponding insert position in 8 inner chambers; on the center of resistor disc pedestal axle sleeve combination 8, a rotating shaft 4 is installed, thereby forms a rotational potentiometer.
The utility model passes through the injection machine single injection-molded with resistor disc pedestal and threaded sleeve, thereby make resistor disc pedestal and threaded sleeve form integrative-structure, not only have stable performance, high pressure resistant effective, the characteristics such as sealing property is high, cost is low, can also play dustproof, moistureproof texts.
