[0040] Example 1

[0041] This embodiment provides a wiring structure, as shown in the attached Figure 1-2 As shown, it is arranged on the contact seat 11.

[0042] The contact seat 11 includes a long side 111 and a short side 112. The contact seat 11 is a roughly rectangular parallelepiped structure, wherein the long side 111 is a side with a longer length, and the short side 112 is a side with a shorter length. Here, the number of long sides 111 is two, and the number of short sides 112 is also two. The contact seat 11 accommodates at least two wiring assemblies, and the number of wiring assemblies here can be adjusted according to actual needs. In this embodiment, two wiring assemblies are described as an example, and the two wiring assemblies are symmetrically arranged in the contact seat 11, and are specifically arranged at a position close to the short side 112 of the contact seat 11. It should also be noted here that the wiring assembly also forms an electrical connection with the static contact inside the contact seat 11, and the electrical connection effect is achieved by rotating the moving contact disk in the contact seat 11. This is a prior art, so it is not described in detail in this embodiment. The wiring direction of the wiring assembly is toward one of the long sides 111. Simply put, the wiring directions of the two wiring assemblies are in the same direction. For example, one of the long sides 111 is located at the front side, and the wiring directions of the two wiring assemblies are toward the front side. The wiring direction here specifically refers to the direction in which the operator extends the operating tool to cooperate with the wiring assembly, specifically the direction in which the screwdriver cooperates with the bolt. The short side 112 is provided with a threading hole 1121 for the external conductive part to pass through, and the wiring assembly is connected to the threading hole 1121. When wiring is required, the external conductive part passes through the threading hole 1121 to cooperate with the wiring assembly, and then the wiring assembly is tightened by the operating tool to achieve electrical connection and tightening effect between the external conductive part and the wiring assembly. The wiring assembly here can be a structure such as a wiring terminal, and the operating tool can be a screwdriver. By unifying the wiring direction, the wiring direction of the entire rotary switch is consistent. This structure greatly increases the convenience of wiring and optimizes the space utilization of the product.

[0043] Specifically, the wiring assembly includes a first wiring assembly 12 and a second wiring assembly 13, the first wiring assembly 12 is located on the left side of the contact seat 11, and the second wiring assembly 13 is located on the right side of the contact seat 11. The first wiring assembly 12 includes a first wiring board 121, and the first wiring board 121 is used to crimp the external conductive member. By driving the bolts on the first wiring assembly 12, the first wiring board 121 is tightly fitted with the external conductive member, thereby achieving the effect of fixing and electrical connection. In this embodiment, the first wiring board 121 is parallel to the long side 111, that is, the first wiring board 121 is parallel to the front side. The second wiring assembly 13 includes a second wiring board 131, and the function of the second wiring board 131 is consistent with that of the first wiring board 121. The second wiring board 131 is parallel to the long side 111. The parallel setting is adopted to better achieve the wiring effect, and the operating tool extends perpendicular to the long side 111 into the contact seat 11 to achieve the cooperation between the operating tool and the wiring assembly.

[0044] Specifically, the first wiring assembly 12 and the second wiring assembly 13 are not located at the same height, but are staggered. For example, the first wiring assembly 12 and the second wiring assembly 13 are located on the same horizontal plane, the first wiring assembly 12 is located at the upper left of the whole, and the second wiring assembly 13 is located at the lower right of the whole, and the two are staggered. Those skilled in the art can also adjust the corresponding positional relationship according to actual needs.

[0045] Specifically, the long side surface 111 is further provided with a first through hole 1111 , and the first through hole 1111 is connected to the threading hole 1121 , and here the first through hole 1111 and the threading hole 1121 are vertically connected.

[0046] Example 2

[0047] This embodiment provides a wiring structure, as shown in the attached Figure 3 As shown, the difference between Example 2 and Example 1 is that the extension line of the second wiring board 131 forms an angle with the extension line of the long side 111, and the angle here is a spatial angle formed by the extension of the same horizontal plane. The setting of the angle forms the effect of oblique wiring, which is suitable for different wiring environments. The angle of the angle is 15°-75°. The definition of the angle makes it convenient for operators to perform wiring at an oblique angle. In this embodiment, the first wiring assembly 12 is located at the lower left of the whole, and the wiring direction is perpendicular to the long side 111. The second wiring assembly 13 is inclined, and its wiring direction is inclined to extend toward one side of the long side 111, so that the wiring method is toward the front side. It should be noted that when wiring the second wiring assembly 13, the screwdriver does not need to pass through the long side 111, and only needs to penetrate from the short side 112 to achieve the effect of tightening the connection.

[0048] In addition, the extension line of the first wiring board 121 forms an angle with the extension line of the long side surface 111, and the extension line of the second wiring board 131 forms an angle with the extension line of the long side surface 111. The setting of the two angles forms an outer eight-shaped structure, which is suitable for different wiring environments. At this time, the two angles are complementary, the smaller angle is an acute angle, and its angle is 15°-75°, and the other angle is complementary. Here, the two angles can also be set arbitrarily, and there is no correlation between the two angles.

[0053] Specifically, the long side 111 is provided with a protrusion 16, the protrusion 16 extends outward, and the mounting hole 15 is provided on the protrusion 16. The volume of the entire switch can be reduced by the protrusion 16 to form a fixing effect. Here, the number of protrusions 16 is two, and the two protrusions 16 are symmetrically arranged. It should be noted that the protrusion 16 is located in the middle area of ​​the long side 111, and there is no intersection between the protrusion 16 and the wiring assembly.

[0054] Specifically, the long screw extends from the lowest contact seat 11 to the highest contact seat 11, and then extends to cooperate with the operating mechanism 14 to achieve the effect of connection and fixation. Here, a nut or a threaded hole can be provided in the operating mechanism 14 to achieve the fixation effect with the long screw, and the long screw can also pass through the entire operating mechanism 14.

[0055] Specifically, one of the two adjacent contact seats 11 is provided with a fixing column 17, and the other of the two adjacent contact seats 11 is provided with a fixing hole 18 that cooperates with the fixing column 17, and the mounting hole 15 passes through the fixing column 17 and the fixing hole 18. The cooperation between the fixing column 17 and the fixing hole 18 forms a positioning and fixing effect of upper and lower splicing, so that the two adjacent contact seats 11 are pre-positioned and installed, and then the overall fixing effect is achieved by long screws. In this embodiment, the fixing column 17 is arranged on the bottom surface of the contact seat 11, and the fixing hole 18 is arranged on the top surface of the contact seat 11, so as to achieve the splicing and fixing effect between the two adjacent contact seats 11.
