[0034] Embodiment 1:

[0035] The switch pin installation structure provided in this embodiment can be applied to various micro switches, such as toggle switches, sliding switches, etc.

[0036] like Figures 1 to 8 As shown, the present embodiment provides a mounting structure for a switch pin, comprising a pin 1 and a base 2, wherein the pin 1 comprises a plug-in block portion 10, a pin portion 11 and a limiting portion 12, wherein the plug-in block portion 10 has an insertion end 100, and the limiting portion 12 is arranged on a side of the plug-in block portion 10 away from the insertion end 100, and a plug-in hole 20 adapted to the plug-in block portion 10 is arranged on the base 2, wherein the plug-in block portion 10 is inserted into the plug-in hole 20 from the outside of the base 2 to the inside of the base 2, and the limiting portion 12 abuts against the outer wall of the base 2, and the length of the plug-in block portion 10 is greater than the depth of the plug-in hole 20, that is, when the plug-in block portion 10 is inserted into the plug-in hole 20, the insertion end 100 will exceed the plug-in hole 20, as shown in FIG. Figure 4 and Figure 5 As shown, the two sides of the insertion end 100 are provided with fixed bending parts 1000, and the fixed bending parts 1000 abut against the inner wall of the base 2. The fixed bending parts 1000 can be pre-processed, and then the pin 1 is plugged into the base 2, and then the fixed bending parts 1000 are bent on the inner side of the base 1, or directly Figure 3 The plug-in block portion 10 of the pin 1 shown is inserted into the plug-in hole 20, and then a special die is used to cut and bend the plug-in block portion 10 from both sides on the inner side of the base 1 to form a fixed bending portion 1000. The pin 1 and the base 2 can be stably fixed through the limiting portion 12 and the fixed bending portion 1000, and it is also convenient to realize automated assembly.

[0037] Through the above arrangement, the problems of difficulty in assembling the pins and the base, low efficiency and inconvenience in realizing automation in the prior art can be solved. Specifically, in the prior art, in addition to the pins and the base being welded together, there is also another pin, such as Figure 8As shown, this type of pin includes a first plate portion 22 and a second plate portion 23, the second plate portion 23 is equivalent to the pin portion 11, and a limiting protrusion 24 is provided at one end of the first plate portion 22 away from the second plate portion 23. When this type of pin is assembled with the base 2, the second plate portion 23 is first passed through the plug-in hole so that the limiting protrusion 24 abuts against the inner wall of the base 2. During this process, the pin needs to be continuously rotated so that the second plate portion 23 passes through the plug-in hole. Therefore, the assembly process is complicated and not conducive to achieving an automated state. Afterwards, it is necessary to perform stamping and bending on both sides of the portion of the first plate portion 22 passing through the plug-in hole so that the pin is fixed to the base. However, stamping at this stage is likely to cause damage to the pin and the base, resulting in a significant increase in the defective rate of the product.

[0038] The thickness of the pin 1 is 0.5 mm-1 mm, preferably 0.8 mm. The pin 1 with this thickness is better in strength and processability.

[0039] Secondly, the limiting portion 12 includes at least one protrusion 120 arranged on the side wall of the plug-in block portion 10. Preferably, the limiting portion 12 includes two protrusions 120, and the two protrusions 120 are respectively arranged on the opposite side walls of the plug-in block portion 10. In the present embodiment, the plug-in block portion 10 is a square block, and the cross-section of the plug-in hole 20 in its width direction is trapezoidal, with its larger opening end facing the inner side of the base 2. The length of the plug-in hole 20 is adapted to the length of the plug-in block portion 10, and the two protrusions 120 are extended in reverse in the length direction of the plug-in block portion 10, and the two protrusions 120 are bent in opposite directions. The plug-in block portion 10, the pin portion 11 and the limiting portion 12 are integrally formed. The pin 1 of this structure is easy to process. It only needs to punch out a pin sheet of a certain shape on the plate, and then bend the two protrusions 120. At the same time, the pin 1 of this structure is more stable when plugged into the base 2.

[0040] At least two plugging holes 20 are arranged at intervals on the base 2 , and the number of the pins 1 is the same as the number of the plugging holes 20 . In the present embodiment, three plugging holes 20 are arranged at equal intervals on the base 2 .

[0041] Furthermore, boss portions 21 are provided on both sides of the base 2, and a positioning plane 210 is provided on the side of the boss portion 21 facing the pin, and guide slopes 211 are provided on both sides of the positioning plane 210. The slopes of the two guide slopes 211 are opposite and are inclined downward toward the positioning plane 210. In addition to being fixed to the switch cover, the boss portion 21 can also be used to position the base 2 when the pin 1 and the base 2 are assembled. The setting of the guide slope 211 is conducive to alignment during positioning.

[0042] Based on the above settings, pin 1 is connected to base 2 by plugging, and plugging is performed from the outside of base 2 to the inside of base 2 at the same time, which is conducive to realizing automated processing, and is not easy to cause damage to the product, reduces the defective rate of the product, and also reduces the difficulty of processing and the requirements for the processor.
