[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figure 1-4This utility model provides a technical solution: a secondary injection-molded cable control and protection device inlet structure, the structure of which includes a cable control and protection device body 1 and a cable 2. The cable 2 is disposed on one side of the cable control and protection device body 1. The cable control and protection device body 1 includes an upper cover 101, a lower cover 102 and an inlet hole 103. The upper cover 101 is snapped onto the top of the lower cover 102. The inlet hole 103 is opened on one side of the lower cover 102. A secondary injection-molded sealing body 3 is fixedly connected to the surface of the cable 2. One end of the cable 2 passes through the secondary injection-molded sealing body 3 and extends into the interior of the inlet hole 103. A clamping plate 4 is abutted against the top of the cable 2. The clamping plate 4 is disposed inside the lower cover 102. Screw mounting holes 5 are opened on both sides of the top of the clamping plate 4. Screws 6 are threadedly connected inside the screw mounting holes 5. The clamping plate 4 is fixedly installed on the inner wall of the lower cover 102 by the screws 6. A sealing ring 8 is provided on the surface of the secondary injection-molded sealing body 3.

[0017] One side of the secondary injection molding sealing line 3 passes through the inlet hole 103 and extends into the interior of the lower cover 102, and a portion of the secondary injection molding sealing line 3 abuts against the inner wall of the lower cover 102.

[0018] Among them, the surface of the secondary injection molding sealing line 3 is provided with a sealing groove 7, and the sealing ring 8 is snapped into the inside of the sealing groove 7. The sealing ring 8 forms a sealing structure with the partial inner wall of the lower cover 102. Specifically, the sealing ring 8 abuts against the inner wall of the lower cover 102 and forms a sealing structure with a partial ring of the lower cover 102, so as to achieve the effect of waterproof sealing.

[0019] The bottom side of the clamping plate 4 is fixedly connected with a first protruding rib 9, which abuts against the top of the cable 2. Specifically, by setting the first protruding rib 9, when the clamping plate 4 is connected to the lower cover 102, the rib pierces into the cable 2 to prevent the cable 2 from coming out, thereby improving the stability of the connection between the cable 2 and the clamping plate 4.

[0020] The inner wall of the lower cover 102 is fixedly connected with a second rib 10, which abuts against the bottom of the cable 2. Specifically, by setting the second rib 10, when the cable clamping plate 4 is connected to the lower cover 102, the rib pierces into the cable 2 to prevent the cable 2 from coming out, thereby improving the stability of the connection between the cable 2 and the lower cover 102.

[0021] Working principle: During assembly and use, first, the sealing ring 8 is placed in the sealing groove 7, thereby inserting the sealing ring 8 into the surface of the secondary injection-molded cable body 3. Then, the cable 2 is connected to the tail cable terminal in the lower cover 102. Next, the secondary injection-molded cable body 3 assembly is installed inside the cable control and protection device body 1. During installation, the cable 2 is inserted into the lower cover 102 through the inlet hole 103, and then the cable 2 is pressed down by the clamping plate 4. Then, the screw 6 is passed through the screw mounting hole 5 to fix the clamping plate 4 to the inner wall of the lower cover 102, thereby also firmly fixing the cable 2 inside the lower cover 102. While inserting the cable 2 into the lower cover 102, the secondary injection-molded cable body is also sealed. One side of the body 3 is inserted into the inlet hole 103, so that the sealing ring 8 and the inner wall of the lower cover 102 abut against each other, and a partial ring of the lower cover 102 forms a sealing structure, which achieves a waterproof sealing effect. By setting the body 3, the clamping plate 4 and the sealing ring 8 through secondary injection molding, the connection between the cable 2 and the control and protection device body 1 on the cable can be made into a modular design, making the product look more exquisite and easy to assemble. With the clamping plate 4 and screws 6, the cable 2 is fixed by the clamping plate 4 after entering the lower cover 102 to prevent it from falling out. The clamping plate 4 is connected to the lower cover 102 by screws 6, which ensures the stability and reliability of the clamping plate 4 and extends the service life of the overall device.
