[0032] The core of the utility model is to provide a cable fixing head to improve the reliability of the overall structure of the cable fixing head;

[0033] Another core of the utility model is to provide an electrical cabinet with the above-mentioned cable fixing head.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1 and Figure 2 As shown, the embodiment of the utility model discloses a cable fixing head, including a main body 100, a clamping nut 200, a hexagonal nut 300 and a sealing member 400. Among them, a plurality of clamping claws 110 are arranged at the first end of the main body 100, and each clamping claw 110 is spaced and distributed on the same circumference with the axis of the main body 100 as the center. When the cable passes through the inner cavity of the main body 100, the clamping nut 200 applies pressure to the clamping claw 110, so that each clamping claw 110 is closed to the inner cavity of the main body 100, and then the cable is compressed to fix the cable. The waterproof ring 410 of the sealing member 400 is located between the clamping nut 200 and the cable to play a role in sealing and waterproof infiltration. At the same time, each clamping claw 110 is connected to the waterproof ring 410 by embedding. The sealing ring 420 of the sealing member 400 is arranged at the second end of the main body 100, and is located between the hexagonal nut 300 and the main body 100 to further improve the sealing ability of the overall structure. The main body 100, the clamping jaw portion 110, the sealing member 400, the waterproof ring portion 410 and the sealing ring portion 420 provided in this embodiment are an integrated structure, which not only reduces the number of overall parts of the cable fixing head and improves the work efficiency of use and installation, but also improves the stability, compactness and strength of the structure, thereby improving the reliability of the overall structure and reducing the problem of loosening of the cable fixing head during use.

[0036] like Figure 2 and Figure 3As shown, the sealing member 400 further includes a connecting portion 430, one end of which is connected to the waterproof ring portion 410, and the other end of which is connected to the sealing ring portion 420, so that the waterproof ring portion 410 is connected to the sealing ring portion 420 through the connecting portion 430 as an integral structure, so that the waterproof ring portion 410 and the sealing ring portion 420 are mutually restricted during use, and the problem of falling off is not likely to occur. At the same time, the main body 100 is provided with a placement groove 130 and a through hole 140, and the connecting portion 430 is placed on the main body 100 through the placement groove 130, and is connected to the sealing ring portion 420 through the through hole 140 communicated with the placement groove 130.

[0037] Furthermore, a reinforcing boss 111 is provided at the end of the clamping jaw 110. When the clamping jaw 110 is connected to the waterproof ring 410, the reinforcing boss 111 of the clamping jaw 110 is embedded in the waterproof ring 410, increasing the contact area between the clamping jaw 110 and the waterproof ring 410, thereby reinforcing the reliability and stability of the connection between the clamping jaw 110 and the waterproof ring 410, so that the clamping jaw 110 and the waterproof ring 410 are not easily separated from each other. In a specific embodiment, each reinforcing boss 111 extends along the circumference of the main body 100, and the extension direction of each reinforcing boss 111 is the same, or those skilled in the art can design the relevant structures of each reinforcing boss 111 according to actual needs, which will not be listed one by one in this article.

[0038] like Figure 3 As shown, the main body 100 is provided with a sealing boss 120, and the sealing ring portion 420 is a groove structure with an opening, so that the sealing boss 120 is embedded in the groove of the sealing ring portion 420 through the opening of the sealing ring portion 420, which not only realizes the connection between the main body 100 and the sealing ring portion 420, but also makes the connection structure between the sealing ring portion 420 and the main body 100 simple and convenient.

[0039] At the same time, the first side wall of the sealing ring portion 420 is connected to the connecting portion 430, and the second side wall of the sealing ring portion 420 is arranged between the sealing boss 120 and the hexagonal nut 300. When the hexagonal nut 300 is installed on the main body 100, the second side wall of the sealing ring portion 420 is pressed and fastened by the mutual cooperation between the hexagonal nut 300 and the sealing boss 120, and the sealing ring portion 420 is further fixed to enhance the stability of the connection of the sealing ring portion 420 on the main body 100. At the same time, the sealing ring portion 420 seals the connection between the hexagonal nut 300 and the main body 100.

[0040] like Figure 3As shown, the placement groove 130 is opened on the inner wall of the main body 100, and then the main body 100 protects the connecting part 430 in the placement groove 130. During the use of the cable fixing head provided in this embodiment, the connecting part 430 is prevented from being broken by external force, thereby improving the overall service life of the cable fixing head provided in this embodiment.

[0041] In addition, the volume of the accommodating space of the mounting groove 130 is gradually reduced along the direction from the clamping claw portion 110 to the sealing boss 120, while ensuring the stability of the connection between the waterproof ring portion 410 and the sealing ring portion 420 through the connecting portion 430, thereby reducing the influence of the opening of the mounting groove 130 on the structural strength of the main body 100, and avoiding the problem of the mounting groove 130 being larger and causing the thickness of the cavity wall of the main body 100 to be reduced and possibly causing breakage.

[0042] In a specific embodiment, the main body 100 provided in this embodiment is made of plastic material, and the seal 400 is made of rubber material. The main body 100 and the seal 400 are injection molded into an integrated structure using a hydraulic injection molding process. During the hydraulic injection molding process, the rubber material flows into the mounting groove 130 to form a connecting portion 430 and flows out through the through hole 140 to form a sealing ring portion 420 in the mold.

[0043] like Figure 1 As shown, the clamping nut 200 and the hexagonal nut 300 in the cable fixing head provided in this embodiment are both installed on the main body 100 by threading, or the technical personnel in this field can connect the clamping nut 200 and the hexagonal nut 300 with the main body 100 according to actual needs, which will not be repeated herein.

[0044] The utility model also discloses an electrical cabinet, including a cable fixing head. Since the electrical cabinet has the above-mentioned cable fixing head, it has all the technical effects of the above-mentioned cable fixing head, which will not be described in detail herein. The electrical cabinet of this embodiment includes electrical equipment such as a control box, a distribution box, and a junction box for installing the cable fixing head.
