[0029] Please see Figures 1-3 As shown, this embodiment provides a one-line positioning structure, including a one-line bracket 2 and rear seats arranged side by side, with adjacent rear seats respectively installed on opposite sides of the one-line bracket 2. One end of the one-line bracket 2 is placed upright on the surface of the rear seat, and the other end of the one-line bracket is pressed down by another rear seat. With the cooperation of the panel and the base, the stability of the one-line bracket 2 after assembly can be ensured, preventing the one-line bracket 2 from moving and ensuring the good performance of products such as switches and switch sockets.

[0030] In some embodiments, please refer to Figures 1-3 As shown, the rear seat includes a first rear seat 1 and a second rear seat 3 arranged side by side, with a gap between them. The middle part of the linear guide bracket 2 is fitted into the gap between the first rear seat 1 and the second rear seat 3. One end of the linear guide bracket 2 is embedded in the first rear seat 1, and the other end is embedded in the second rear seat 3. By clamping the middle part of the linear guide bracket 2 with the first rear seat 1 and the second rear seat 3, and limiting the two ends of the linear guide bracket 2, the linear guide bracket 2 can be accurately limited to the first rear seat 1 and the second rear seat 3. This prevents the linear guide bracket 2 from moving in a direction perpendicular to the first rear seat 1 and the second rear seat 3, and also prevents it from translating along the plane where the first rear seat 1 and the second rear seat 1 are located. This ensures the stability of the linear guide bracket 2 installation and improves the performance and service life of products such as switches and switch sockets.

[0031] In some embodiments, please refer to Figures 1-3As shown, the first rear seat 1 is provided with a first positioning groove 11, which passes through the side wall of the first rear seat 1 near the second rear seat 3. The second rear seat 3 is provided with a second positioning groove 31, which passes through the side wall of the second rear seat 3 near the first rear seat 1. The first positioning groove 11 and the second positioning groove 31 are located on opposite surfaces. The positions of the first positioning groove 11 and the second positioning groove 31 are set according to the shape of the wire guide bracket 2. Usually, for ease of processing, the part of the wire guide bracket 2 that mates with the first positioning groove 11 and the second positioning groove 31 is set as a long strip.

[0032] For example, the first rear seat 1 and the second rear seat 3 can be produced by injection molding. In order to reduce the mold opening cost, the first rear seat 1 and the second rear seat 3 can be processed into the same structure. The two rear seats with the same structure are installed side by side in the base, and a gap is left between the two rear seats for the middle part of the wire guide bracket 2 to be clamped.

[0033] It should be noted that the first rear seat 1 is provided with a first terminal frame 12, and the second rear seat 3 is provided with a second terminal frame 32. Both the first terminal frame 12 and the second terminal frame 32 are equipped with terminal block assemblies 4. The number of first terminal frames 12 and second terminal frames 32 installed is set according to actual needs.

[0034] In some embodiments, please refer to Figure 4 and Figure 5 As shown, the wire guide bracket 2 includes a wire clamping piece 21, a first adapter piece 22, a second adapter piece 23, and a movable contact piece bracket 24 connected in sequence. The movable contact piece bracket 24 has a movable contact piece mounting position, and a movable contact piece 6 is mounted at each mounting position. The contact surface between the movable contact piece mounting position and the movable contact piece 6 is an arc surface to allow the movable contact piece 6 to swing. The number of movable contact piece mounting positions is not less than two, determined based on the number of movable contact pieces 6 installed. Figure 5The device has two movable contact mounting positions, providing positioning and mounting for the two contacts. Correspondingly, a first terminal frame 12 and two second terminal frames 32 are provided. A limiting protrusion 241 is provided between adjacent movable contact mounting positions, and a limiting groove 242 is also provided on the movable contact bracket 24. The limiting protrusion 241 and the limiting groove 242 are positioned correspondingly and located on opposite sides of the movable contact bracket 24. One section of the movable contact bracket 24 is installed in the first positioning groove 11, and the other section is installed in the second positioning groove 31. Further, the depth of the second positioning groove 31 located on the side wall of the second rear seat 3 is set to be less than the depth of other positions of the second positioning groove 31. This creates a shoulder on the side wall of the second rear seat 3, and the limiting groove 242 fits perfectly with the shoulder, forming a cross-shaped positioning for the one-line connector bracket 2, resulting in better stability. Furthermore, the width of the limiting protrusion 241 is greater than the width of the limiting groove 242, which strengthens the structural strength of the one-line support bracket 2. After the limiting groove 242 is engaged with the shoulder, a portion of the protrusion 241 is engaged between the first rear seat 1 and the second rear seat 3, further preventing the one-line support bracket 2 from shaking.

[0035] In some embodiments, please refer to Figures 1-3 As shown, the second rear seat 3 is provided with a slot for mounting the first adapter piece 22 and a pair of slots for mounting the second adapter piece 23, which limit the movement of the one-line support bracket 2 in multiple places.

[0036] In some embodiments, please refer to Figures 1-4 As shown, the one-wire bracket 2 is installed on any of the second terminal frames 32 via the terminal assembly 4. Specifically, the wire clamp 21 passes through the terminal 41 in the terminal assembly 4 and is installed on any of the second terminal frames 32, thereby connecting the one-wire bracket 2 to the live wire. Both the first terminal frame 12 and the other second terminal frame 32 are equipped with stationary contacts 5 via the terminal assembly 4, enabling the stationary contacts 5 to connect to the neutral wire. The stationary contact 5 connected to the first terminal frame 12 is located on the side of the first rear seat 1 near the base (usually referred to as the back or bottom of the first rear seat 1), and the stationary contact 5 connected to the second terminal frame 32 is located on the side of the second rear seat 3 near the panel (usually referred to as the front or top of the first rear seat 1). Of course, the positions of the stationary contacts 5 connected to the first terminal frame 12 and the stationary contacts 5 connected to the second terminal frame 32 can be interchanged. Two moving contacts 6 correspond one-to-one with two stationary contacts 5. By swinging the moving contact 6, the moving contact 6 can make contact with the corresponding stationary contact 5 to conduct electricity and separate to de-energize, thereby realizing the power-on and power-off functions of products such as switches and switch sockets.

[0037] The one-line positioning structure provided by this utility model features multiple limiting connections on the rear seat, ensuring precise positioning and stable assembly without shifting, thus reducing the difficulty of the injection molding process. The base and panel only serve as auxiliary positioning components, lowering the injection molding requirements for the base and panel. Deformation of the base and panel will not affect the stability of the one-line bracket 2, guaranteeing the good performance of switches, switch sockets, and other products, and extending their service life.

[0038] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
