[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 4 An electrical wiring connector includes multiple connectors 1, which are interconnected by some means such as bolts, snaps, etc. to form an overall wiring frame. On the front side of the multiple connectors 1, we fixedly connect a front plate 3 to provide a unified connection interface. In addition, connection holes are set on the front side of each connector 1, and these connection holes are used to easily connect with equipment or lines.

[0023] In order to clamp and fix the connecting line, we set up a clamping mechanism on the front side of each connecting member 1, and the clamping mechanism is mainly composed of a top plate 7, a lifting plate 8, an upper plate 5 and a lower plate 6. The bottom of the lower plate 6 is fixedly connected to the top of the front plate 3, and the top of the upper plate 5 is fixedly connected to the bottom of the top plate 7. The rear side of the top plate 7 is slidably connected to the front side of the connecting member 1, so that the top plate 7 can move back and forth along the connecting member 1. The front side of the top plate 7 is fixedly connected to the rear side of the lifting plate 8. Therefore, when the lifting plate 8 is operated, the top plate 7 can be driven to move together. Semicircular grooves are opened on the side where the upper plate 5 and the lower plate 6 are close to each other. When the top plate 7 moves, the upper plate 5 will move accordingly, so that the semicircular grooves on the upper plate 5 and the lower plate 6 can clamp and fix the connecting line.

[0024] In order to further enhance the stability of the clamping mechanism, we set up a fixing mechanism, which includes a clamping ring 10, a clamping column 11 and an arc groove 12. The shape of the clamping ring 10 is set to be U-shaped, and its two ends are respectively fixedly mounted on the rotating rod, and the two ends of the rotating rod are rotatably connected to block No. 1. One side of block No. 1 is fixedly connected to both sides of the upper plate 5, and one end of the clamping column 11 is fixedly connected to both sides of the lower plate 6. The clamping ring 10 is mounted on the clamping column 11. When the lifting plate 8 is pressed down, the upper plate 5 will move downward, and the clamping ring 10 and the clamping column 11 fit together and fix the upper plate 5 and the lower plate 6, thereby fixing the clamping mechanism. The arc groove 12 is set to facilitate the opening of the clamping ring 10, and then facilitate the inspection of the connection between the line and the connector 1.

[0025] The present application can be used in the field of electrical connectors, and can also be used in other fields applicable to the present application.

[0026] Embodiment 2

[0027] refer to Figure 1-Figure 4 , based on the improvement of the first embodiment, an electrical wiring connector with a modular structure includes:

[0028] In order to reduce the compression damage to the connection line, we set a soft pad 9 on the inner wall of the semicircular groove of the upper plate 5 and the lower plate 6, such as a rubber or silicone material, to provide a soft clamping environment.

[0029] In addition, in order to ensure the stable sliding of the top plate 7 on the connecting member 1, a slider 15 is set on the rear side of the top plate 7, and a slide groove 4 compatible with the slider 15 is opened on the front side of the connecting member 1. The shapes of the slider 15 and the slide groove 4 are both set to be T-shaped to increase the sliding stability and prevent the slider 15 from falling off the slide groove 4.

[0030] In order to facilitate the fixation of the entire module, we fixedly connected the side panels 2 on both sides of the module, and opened mounting holes on the two side panels 2 so that the module can be fixed in the required position by fasteners such as bolts and screws.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
