DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figures 1 to 7The utility model provides a technical solution: an insulating piercing wire clamp with good sealing performance, comprising an upper insulating shell 1 and a lower insulating shell 2, a bolt 17 is inserted between the upper insulating shell 1 and the lower insulating shell 2, a piercing blade 12 is installed on both the upper insulating shell 1 and the lower insulating shell 2, an upper waterproof rubber pad 16 is installed on one side of the upper insulating shell 1, and a lower waterproof rubber pad 15 is installed on one side of the lower insulating shell 2, and an empty groove 13 is opened on the lower waterproof rubber pad 15, and a sealing convex edge 19 that matches the empty groove 13 is integrally formed on the upper waterproof rubber pad 16. When the upper waterproof rubber pad 16 is tightly attached to the lower waterproof rubber pad 15, the sealing convex edge 19 enters the empty groove 13, thereby increasing the sealing performance of the lower waterproof rubber pad 15 and the lower waterproof rubber pad 15. The contact area between the upper and lower waterproof rubber pads 16 improves the sealing performance, and the pressure plate 8 cooperates with the sealing seat 10 to press the arc-shaped sealing plate 9 to the outside of the cable, which plays a secondary sealing role and further improves the sealing performance, preventing rainwater from entering the lower waterproof rubber pad 15 and the upper waterproof rubber pad 16 to contact the cable. The side walls of the lower waterproof rubber pad 15 and the upper waterproof rubber pad 16 are both provided with arc-shaped sealing plates 9, the upper insulating shell 1 is provided with a pressure plate 8, and the lower insulating shell 2 is provided with a sealing seat 10. The middle part of the sealing seat 10 is provided with a pressure groove 11 that cooperates with the pressure plate 8. The pressure groove 11 is used to avoid the pressure plate 8 to prevent the pressure plate 8 from being blocked by the sealing seat 10, resulting in the upper insulating shell 1 and the lower insulating shell 2 being unable to get close.

[0022] The outer side wall of the upper insulating shell 1 is provided with a baffle 5, and the baffle 5 is used to block the gap between the side surfaces of the upper insulating shell 1 and the lower insulating shell 2 to prevent rainwater from entering.

[0023] A sealing gasket 20 is provided on the inner side wall of the baffle 5 , and the sealing gasket 20 is used to improve the sealing performance between the baffle 5 and the lower insulating shell 2 .

[0024] Among them, a water blocking plate 14 is provided on the top of the upper insulating shell 1, and the top of the bolt 17 is threadedly connected with a torque nut 4, which is used to push the upper insulating shell 1 to move, so that the piercing blade 12 pierces into the cable.

[0025] Among them, a fixing buckle 3 is integrally formed on the outer side of the lower insulating shell 2, and a buckle 18 is installed on the inner side of the fixing buckle 3. The buckle 18 cooperates with the fixing buckle 3 to install the waterproof cap 6 on the lower insulating shell 2. A connecting rope 7 is connected to the buckle 18, and one end of the connecting rope 7 is connected to the waterproof cap 6. The waterproof cap 6 is used to seal the cable end.

[0026] Among them, the lower waterproof rubber pad 15, the upper waterproof rubber pad 16, the arc-shaped sealing plate 9, the sealing flange 19, the sealing pad 20 and the waterproof cap 6 are all made of rubber. Rubber has good elasticity and strength, can fit very closely with the contact surface, and thus can achieve a good sealing effect. It also has strong corrosion resistance and a long service life.

[0027] Specifically, when in use, the upper insulating shell 1 and the lower insulating shell 2 are clamped on the outside of the cable, and the cable is between the lower waterproof rubber pad 15 and the upper waterproof rubber pad 16. Then the torque nut 4 is turned to make it move downward. The torque nut 4 makes the upper insulating shell 1 move downward through the water-blocking plate 14, and the upper insulating shell 1 and the lower insulating shell 2 gradually approach each other. The lower waterproof rubber pad 15 and the upper waterproof rubber pad 16 gradually stick to the outside of the cable, and the sealing convex edge 19 enters the empty groove 13. At the same time, the puncture blade 12 starts to puncture the cable, and the pressure plate 8 and the sealing seat 10 will squeeze the arc-shaped sealing plate 9, so that the arc-shaped sealing plate 9 sticks to the outside of the cable, which plays a secondary sealing role to prevent rainwater from entering between the lower waterproof rubber pad 15 and the upper waterproof rubber pad 16.
