Description

Technical Field

[0001] The utility model relates to a switch potentiometer, in particular to a sealed waterproof switch potentiometer. Background Art

[0002] Conventional potentiometers include a carbon diaphragm, which is typically exposed. If left exposed for extended periods, it can oxidize, causing resistance fluctuations. The exposed connection between the carbon diaphragm and the terminals can become loose. Furthermore, gaps in the potentiometer housing can allow moisture or particulate matter to enter the potentiometer, affecting its proper operation. Potentiometers with this exposed structure also fail to meet waterproofing requirements. Utility Model Content

[0003] The utility model aims to solve the above-mentioned defects and provides a sealed waterproof potentiometer with a switch.

[0004] In order to overcome the defects existing in the background technology, the technical solution adopted by the present invention to solve its technical problems is: this sealed waterproof potentiometer with a switch includes a shell, the upper end of the shell is connected to the switch, a carbon diaphragm and terminals are provided in the shell, the surface of the carbon diaphragm is provided with a layer of plastic coating, the switch is connected to the shell by a paper board and plastic drops through hot riveting, and a sealant layer is provided on the upper surface of the shell and around the switch.

[0005] According to another embodiment of the present invention, the terminal is further placed on the groove surface of the carbon diaphragm, and the connection is connected by plastic encapsulation.

[0006] The beneficial effects of the utility model are as follows: the sealed waterproof potentiometer with switch has a simple structure and can be effectively waterproof and dustproof, so that the potentiometer can be used for a long time in a harsh environment without functional problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0008] Figure 1 It is a structural diagram of the utility model;

[0009] Among them: 1. switch, 2. paper board, 3. sealant layer, 4. housing, 5. terminal, 6. carbon diaphragm. DETAILED DESCRIPTION

[0010] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, but not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0011] like Figure 1 As shown, the figure includes a housing 4, the upper end of which is connected to the switch 1. A carbon diaphragm 6 and terminals 5 are located within the housing 4. The surface of the carbon diaphragm 6 is coated with a plastic coating. The switch 1 is connected to the housing 4 via a paper board 2 and plastic droppers through heat riveting. A sealant layer 3 is provided on the upper surface of the housing 4, surrounding the switch 1. The plastic coating on the carbon diaphragm 6 prevents oxidation, ensuring that its resistance value remains stable over time.

[0012] The terminal 5 is placed on the groove surface of the carbon diaphragm 6, and the connection is connected by plastic coating. The connection between the carbon diaphragm 6 and the terminal 5 is coated with plastic to strengthen the fixation.

[0013] The overall structure is no longer connected by a shell. The switch 1 is connected by a paper board 2 and a plastic drop through a hot riveting method, and it can also protect the internal parts.

[0014] Finally, a layer of sealant is applied to the potentiometer switch device to form a sealant layer 3, which prevents water from entering the potentiometer and prolongs the service life of the potentiometer.

[0015] This new structure potentiometer is effectively waterproof and dustproof, allowing the potentiometer to be used for a long time in harsh environments without any functional problems.

[0016] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
