[0001] This utility model relates to the field of power switch technology, and more specifically, to a solderless structure for a power switch. Background Technology

[0002] A power switch is a device used to control the on / off state of power in a circuit. It can connect or disconnect the electrical connection between the power source and electrical equipment, thereby enabling the equipment to be turned on and off. Currently, in the production process, the housing of a power switch is generally assembled using screws or welding.

[0003] Some power switches use traditional mechanical connection methods such as screw fastening. This method requires a lot of time and manpower during assembly, and the screws and other connecting parts are prone to loosening, affecting the stability and reliability of the power switch. Some power switches that use welding for connection have problems such as low assembly efficiency, high production cost, difficult maintenance, and safety hazards. Utility Model Content

[0004] In order to overcome the problems and defects in the prior art, this utility model provides a solderless structure for a power switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a solderless structure for a power switch, comprising an upper housing of the power switch, a switch button mounted on the top of the upper housing of the power switch, a lower housing of the power switch disposed at the bottom of the upper housing of the power switch, and a disassembly and assembly mechanism provided between the upper housing of the power switch and the lower housing of the power switch.

[0006] The disassembly and assembly mechanism includes a connecting slot, which is formed on the bottom surface of the upper housing of the power switch. A connecting plate is fixedly connected to the top of the lower housing of the power switch. Fixing grooves are formed on both sides of the connecting plate. An inner cavity is formed inside the upper housing of the power switch. A connecting spring is fixedly connected to one side of the inner wall of the inner cavity. A movable locking post is fixedly connected to one end of the connecting spring. A through-slide groove is formed on the top surface of the inner wall of the inner cavity. A movable plate is fixedly connected to the top of the movable locking post. A movable block is fixedly connected to the top of the movable plate.

[0007] Preferably, the top surface of the upper housing of the power switch has an embedded groove, the movable block is slidably connected to the embedded groove, and the depth of the embedded groove is adapted to the height of the movable block.

[0008] Preferably, the through groove is formed on the bottom surface of the inner wall of the embedded groove, and the through groove is slidably connected to the movable plate.

[0009] Preferably, the number of connecting springs, movable pins, through grooves, movable plates, and movable blocks is set to multiple, and the number of connecting plates and connecting slots is set to two.

[0010] Preferably, a positioning hole is provided on the bottom surface of the upper housing of the power switch, and a positioning pin is fixedly connected to the top of the lower housing of the power switch, and the positioning hole and the positioning pin are movably engaged.

[0011] Preferably, the connecting spring can be made of high-strength stainless steel.

[0012] Preferably, both the upper and lower housings of the power switch are made of flame-retardant plastic.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a disassembly and assembly mechanism, and through the cooperation of the connecting plate and the connecting slot, as well as the engagement of the fixed slot and the moving pin, the upper and lower housings of the power switch can be quickly connected. During the assembly process, no welding operation is required, which greatly improves the assembly efficiency and reduces the production cost. When it is necessary to repair the power switch or replace internal components, the connection between the upper and lower housings can be easily released by pushing the moving block. This is convenient and quick, reducing maintenance time and difficulty. The weld-free structure avoids the problems of low installation efficiency and troublesome installation of fasteners such as screws, and also avoids problems such as false welding and missing welding that may occur during the welding process, reducing circuit failures and safety hazards caused by poor welding.

[0015] 2. By connecting the fixing slots on both sides of the connecting plate with the moving pins, and by cooperating with the positioning holes and positioning pins, double fixation is provided for the upper and lower housings of the power switch, ensuring the stability of the connection. During use, the power switch will not easily come apart due to external impact or vibration, ensuring the normal operation of the equipment. The connecting spring made of high-strength stainless steel has good elastic recovery ability and fatigue resistance, and can provide stable elastic force for the moving pins for a long time, further enhancing the reliability of the connection. The sliding connection between the moving block and the embedded groove, and the matching depth of the embedded groove with the height of the moving block, allows the moving block to be completely retracted into the embedded groove when not pushed by external force, without affecting the appearance of the power switch, and also avoiding misoperation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As attached Figure 1-5 The power switch shown has a solderless structure, including an upper power switch housing 1, a switch button 2 installed on the top of the upper power switch housing 1, a lower power switch housing 3 provided at the bottom of the upper power switch housing 1, and a disassembly and assembly mechanism provided between the upper power switch housing 1 and the lower power switch housing 3.

[0024] The disassembly and assembly mechanism includes a connecting slot 4, which is located on the bottom surface of the upper housing 1 of the power switch. A connecting plate 5 is fixedly connected to the top of the lower housing 3 of the power switch. Fixing grooves 6 are provided on both sides of the connecting plate 5. An inner cavity 7 is provided inside the upper housing 1 of the power switch. A connecting spring 8 is fixedly connected to one side of the inner wall of the inner cavity 7. A movable locking post 9 is fixedly connected to one end of the connecting spring 8. A through groove 10 is provided on the top surface of the inner wall of the inner cavity 7. A movable plate 11 is fixedly connected to the top of the movable locking post 9. A movable block 12 is fixedly connected to the top of the movable plate 11.

[0025] As attached Figure 1 , 2 As shown in Figures 3 and 5, an embedded groove 13 is provided on the top surface of the upper housing 1 of the power switch. The moving block 12 is slidably connected to the embedded groove 13. The depth of the embedded groove 13 is adapted to the height of the moving block 12. A through groove 10 is provided on the bottom surface of the inner wall of the embedded groove 13. The through groove 10 is slidably connected to the moving plate 11, so that the moving block 12 can be completely stored in the embedded groove 13 when it is not pushed by external force, which does not affect the appearance of the power switch and also avoids misoperation.

[0026] As attached Figure 1-5 As shown, the number of connecting spring 8, movable locking post 9, through slide 10, movable plate 11 and movable block 12 are all set to multiple, and the number of connecting locking plate 5 and connecting locking slot 4 are all set to two, which improves the overall stability of the switch after installation.

[0027] As attached Figure 3 , 4 As shown, a positioning hole 14 is provided on the bottom surface of the upper housing 1 of the power switch, and a positioning pin 15 is fixedly connected to the top of the lower housing 3 of the power switch. The positioning hole 14 and the positioning pin 15 are movably engaged, which facilitates positioning, improves installation efficiency, and enhances the installation and fixing effect.

[0028] As attached Figure 1-5 As shown, the connecting spring 8 can be made of high-strength stainless steel, and the upper housing 1 and lower housing 3 of the power switch are both made of flame-retardant plastic, which improves the service life and safety of the disassembly and assembly mechanism.

[0029] Working principle of this utility model: This utility model provides a solderless structure for a power switch. When the power switch needs to be assembled, the connecting plate 5 at the top of the lower housing 3 of the power switch is inserted into the connecting slot 4 at the bottom of the upper housing 1 of the power switch. The connecting plate 5 plays the role of initial positioning and connecting the upper and lower housings. As the connecting plate 5 is inserted into the connecting slot 4, when the fixing slots 6 on both sides of the connecting plate 5 move to the position corresponding to the moving pin 9, the moving pin 9 will be locked into the fixing slot 6 under the elastic force of the connecting spring 8, thereby firmly fixing the connecting plate 5 in the connecting slot 4, realizing a stable connection between the upper housing 1 and the lower housing 3 of the power switch.

[0030] When the power switch needs to be disassembled, the moving block 12 on the top surface of the upper housing 1 of the power switch is pushed. The moving block 12 is slidably connected to the inner groove 13, and the depth of the inner groove 13 is adapted to the height of the moving block 12. This allows the moving block 12 to be completely stored in the inner groove 13 without being pushed by external force, without affecting the appearance of the power switch. The moving plate 11 fixedly connected to the bottom of the moving block 12 moves together with the moving block 12. The moving plate 11 slides in the through slide 10. The through slide 10 is opened on the bottom surface of the inner wall of the inner groove 13, providing a stable sliding track for the moving plate 11. The moving pin 9 fixedly connected to the bottom of the moving plate 11 overcomes the elastic force of the connecting spring 8 under the action of the moving plate 11 and exits from the fixing grooves 6 on both sides of the connecting plate 5, releasing the fixing of the connecting plate 5. At this time, the connecting plate 5 can be pulled out from the connecting groove 4 to complete the disassembly of the power switch.

[0031] When assembling the power switch, the positioning pin 15 on the top of the lower housing 3 of the power switch is inserted into the positioning hole 14 on the bottom of the upper housing 1 of the power switch, which plays an auxiliary positioning role and ensures that the connecting plate 5 can be accurately inserted into the connecting slot 4, thereby improving the efficiency and accuracy of assembly.

[0032] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
