[0028] Example

[0029] A resistor auxiliary disassembly and assembly mechanism includes a disassembly and assembly mechanism body for installing and fixing a resistor 6, the disassembly and assembly mechanism body includes a first mounting seat 1 and a second mounting seat 2 which are symmetrically distributed along the length direction of the resistor 6, the first mounting seat 1 and the second mounting seat 2 are welded to corresponding positions on a PCB board 8, a first assembly cavity 4 and a second assembly cavity 10 are respectively provided on opposite sides of the first mounting seat 1 and the second mounting seat 2, the second assembly cavity 10 is adapted to the size of an end cap 7 of the resistor 6, an elastic mounting portion which can be laterally extended or contracted is provided in the first assembly cavity 4, one end of the resistor 6 is assembled in the second mounting cavity, and the other end is detachably connected to the elastic mounting portion, and the spacing between the elastic mounting portion and the side wall of the second assembly cavity 10 in a natural state is smaller than the length of the resistor 6.

[0030] In this embodiment, Figure 1 As shown, the disassembly and assembly mechanism body is used to install and fix the resistor 6. The first mounting seat 1 and the second mounting seat 2 are symmetrically distributed along the length direction of the resistor 6 and are fixed on the PCB board 8 by welding. The first assembly cavity 4 and the second assembly cavity 10 are respectively located on the opposite sides of the first mounting seat 1 and the second mounting seat 2, and are used to accommodate and fix the two ends of the resistor 6. Figure 3As shown, the size of the second assembly cavity 10 matches the end cap 7 of the resistor 6, ensuring that the resistor 6 can be firmly installed therein. The elastic mounting portion in the first assembly cavity 4 can be extended or contracted laterally for detachable connection with the other end of the resistor 6. When the elastic mounting portion is in a natural state, the distance between it and the side wall of the second assembly cavity 10 is less than the length of the resistor 6, which helps to ensure that the resistor 6 is not easy to loosen after assembly. When the resistor 6 needs to be replaced, the end cap 7 of the resistor 6 is connected to the elastic mounting portion, and the elastic mounting portion is compressed in a direction away from the second mounting seat 2 to secure the other end cap 7 of the resistor 6. Assemble it in the second assembly cavity 10 to leave space, then release the compression on the elastic mounting part, and assemble the other end cap 7 of the resistor 6 in the second assembly cavity 10. The elastic mounting part generates an elastic force toward the second mounting seat 2, and firmly presses the resistor 6 between the two mounting seats to complete the replacement of the resistor 6. If the resistor 6 needs to be removed, it is only necessary to compress the elastic mounting part again toward the side away from the second mounting seat 2 to leave space for the resistor 6 to be taken out of the second assembly cavity 10, and finally remove the resistor 6 from the elastic mounting part. The entire disassembly and assembly process is simple and convenient, saving time and effort, and improving the disassembly and assembly efficiency of the resistor 6.

[0031] Furthermore, the elastic mounting portion includes an elastomer 5 and a fixing seat 3, the fixing seat 3 is circular, and the fixing seat 3 is adapted to the size of the first assembly cavity 4. One end of the elastomer 5 is fixed to the side wall of the first assembly cavity 4, and the other end is fixed to the outside of the fixing seat 3. The inside of the fixing seat 3 is provided with a third assembly cavity 11 adapted to the end cap 7 of the resistor 6, and the other end of the resistor 6 is assembled in the third assembly cavity 11.

[0032] Specifically, Figure 4As shown, the fixing seat 3 is circular, and its size is adapted to the first assembly cavity 4, which means that the fixing seat 3 can be firmly installed in the first assembly cavity 4 to provide stable support. One end of the elastic body 5 is fixed to the side wall of the first assembly cavity 4, and the other end is fixed to the outside of the fixing seat 3. The third assembly cavity 11 is located on the inner side of the fixing seat 3, and its size is adapted to the end cap 7 of the resistor 6, which means that the other end of the resistor 6 can be tightly assembled in the third assembly cavity 11. When one end of the resistor 6 is inserted into the third assembly cavity 11 and the elastic body 5 is compressed in the direction away from the second mounting seat 2, the elastic body 5 will be deformed due to the pressure, thereby leaving space for the other end of the resistor 6 to be installed in the second assembly cavity 10, and the resistor 6 will be installed in the second assembly cavity 10. After the other end of the resistor 6 is assembled with the second assembly cavity 10, the elastomer 5 generates a certain elastic force in the direction of the second mounting seat 2, providing necessary elastic support for the fixation of the resistor 6, ensuring the stability and firmness of the resistor 6 on the PCB board 8, and the elastomer 5 is selected from a material with high elasticity, good wear resistance and fatigue resistance to ensure that it can maintain stable performance under long-term use. The shape and size of the elastomer 5 should be accurately calculated and optimized to ensure that while providing sufficient elasticity, it will not affect the fixing effect of the resistor 6 due to excessive deformation. The inner walls of the third assembly cavity 11 and the second assembly cavity 10 can be rough surfaces to increase the friction between the end cap 7 of the resistor 6 and improve the installation firmness of the resistor 6.

[0033] Furthermore, the elastic body 5 is provided in plurality, and the plurality of elastic bodies 5 are distributed in the first assembly cavity 4 in a rectangular array or an annular array.

[0034] Specifically, Figure 5 As shown, when multiple elastic bodies 5 are arranged in a rectangular array, they form a grid-like support structure, which can provide multiple contact points to support the resistor 6, thereby ensuring the stability and balance of the resistor 6 on the PCB board 8. Figure 6 As shown, if a plurality of elastic bodies 5 are arranged in a ring array, they will form a circular support structure, which can provide all-round support so that the resistor 6 can be stably supported when subjected to force in any direction.

[0035] Furthermore, the elastic body 5 is a spring or an elastic sleeve.

[0036] Specifically, the spring is a common elastomer 5, which can provide the necessary supporting force by its own compression or stretching. In the auxiliary disassembly and assembly mechanism of the resistor 6, the spring can be installed in the first assembly cavity 4, with one end fixed to the side wall of the assembly cavity and the other end connected to the fixing seat 3. When the resistor 6 is inserted into the assembly mechanism, the spring will be compressed, thereby providing a stable reverse supporting force.

[0037] The elastic sleeve is an elastic tubular structure. In the auxiliary disassembly and assembly mechanism of the resistor 6, the elastic sleeve can be installed in the first assembly cavity 4 and connected to the fixing seat 3. When the resistor 6 is inserted into the assembly mechanism, the elastic sleeve will be tightly wrapped around the end cap 7 of the resistor 6 to achieve stable fixation.

[0038] Furthermore, the disassembly and assembly mechanism body is made of conductive material.

[0039] Specifically, the disassembly and assembly mechanism body is made of conductive material, which means that it can serve as an electrical connection bridge between the resistor 6 and the PCB board 8. This design not only simplifies the circuit layout, but also improves the reliability of the circuit.

[0040] The disassembly and assembly mechanism body itself is conductive, and no additional conductive material or connector is required when installing the resistor 6, which simplifies the installation process. The conductive material can be made of stainless steel, aluminum, copper or other materials.

[0041] Furthermore, the first mounting seat 1 and the second mounting seat 2 are both rectangular.

[0042] Specifically, Figure 2 and Figure 3 As shown, when the rectangular first mounting seat 1 and the second mounting seat 2 are welded to the PCB board 8, the welding area can be increased and the firmness of the connection with the PCB board 8 can be improved. The rectangular mounting seat can provide a more stable support surface to ensure the stable installation of the resistor 6 on the PCB board 8. The rectangular structure has high rigidity and strength and can effectively resist external shocks and vibrations. The rectangular design makes the matching between the mounting seat and the mounting hole or other positioning structure on the PCB board 8 more accurate, thereby achieving accurate positioning of the resistor 6, which helps to reduce installation errors and improve the performance and reliability of the circuit. The rectangular structure is relatively simple and easy to manufacture and process. The use of standardized molds and tools can efficiently produce a large number of mounting seats and reduce costs.

[0043] Furthermore, a plurality of arched holes 9 are provided on the bottom surfaces of the first mounting seat 1 and the second mounting seat 2 , and the plurality of arched holes 9 are spaced apart in the length direction of the first mounting seat 1 and the second mounting seat 2 .

[0044] Furthermore, the arched hole 9 penetrates the first mounting seat 1 and the second mounting seat 2 along the width direction.

[0045] Specifically, Figure 2 and Figure 3As shown, the design of the arched hole 9 enables the mounting base to disperse the force to more materials when subjected to external force, thereby improving its bearing capacity and stability. This structure is similar to the principle of an arched bridge, which enables the material to function more effectively when under pressure. By arranging the arched hole 9 on the bottom surface, the weight of the mounting base can be reduced without sacrificing strength. This is of great significance for application scenarios that require weight control, such as aerospace, precision instruments and other fields. If the arched holes 9 are through along the width direction of the mounting base, they can be used as ventilation holes to facilitate air circulation inside and outside the mounting base. For electronic equipment that requires heat dissipation, it can improve its heat dissipation performance and extend its service life.

[0046] Furthermore, the end cap 7 of the resistor 6 and the second assembly cavity 10 are internally sleeved in an interference fit.

[0047] Furthermore, the end cap 7 of the resistor 6 and the third assembly cavity 11 are internally sleeved in an interference fit.

[0048] Specifically, the two ends of the resistor 6 are respectively sleeved with the second assembly cavity 10 and the third assembly cavity 11 by interference fit, so that the resistor 6 is more secure after installation. Interference fit is an assembly method in which the two mating parts will produce a certain amount of interference after assembly, that is, the size of one part is slightly larger than the corresponding size of the other part. This matching method can generate a preload force to form a close contact between the parts, thereby enhancing the stability and sealing of the assembly. The inner sleeve design between the end cap 7 of the resistor 6 and the assembly cavity means that the end cap 7 is inserted into the assembly cavity to form a nested structure. This design can provide a larger contact area and further enhance the stability of the assembly.

[0049] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
