[0027] 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.

[0028] Embodiment 1

[0029] See also Figure 1-11 , the utility model provides a technical solution:

[0030] A wiring line card with a multi-layer waterproof structure, comprising: a line card bottom shell 1, a surface of the line card bottom shell 1 is slidably connected to a line card lower cover 2, and one side of the line card lower cover 2 is rotatably connected to a line card upper cover 19;

[0031] Also includes:

[0032] The compensation component 3 is arranged on the surface of the line card lower cover 2. The compensation component 3 enhances the sealing and waterproof performance of the connection between the line card bottom shell 1 and the line card lower cover 2, which can reduce the possibility of aging, deformation or loss of elasticity of the sealing ring, resulting in a decrease in the waterproof performance of the line card.

[0033] The compensation component 3 includes a support frame 14, which is used to fix the support elastic strip 7 and provide a support point for the elastic strip 7 to fix the support frame 28. The surface of the support frame 4 is provided with a receiving groove 15 for accommodating a fixing frame 6. The surface of the receiving groove 15 is slidably connected with the fixing frame 6. The surface of the fixing frame 6 is fixedly connected to the line card bottom shell 1. When the line card bottom shell 1 is covered on the line card lower cover 2, the fixing frame 6 will pass through the receiving groove 15 and the receiving groove 29. On the one hand, it is to make the support frame 28 fit tightly to the surface of the line card bottom shell 1, and on the other hand, it is to make the support frame 28 and the support frame 14 maintain the same vertical position to prevent the position of the support frame 28 from shifting due to the elastic force of the elastic strip 7 when the line card bottom shell 1 fits the surface of the support frame 28.

[0034] The surface of the support frame 1 4 is fixedly connected with a plurality of elastic strips 7 for elastically supporting the support frame 2 8. The surfaces of the plurality of elastic strips 7 are fixedly connected with the support frame 2 8. The material of the support frame 2 8 is the same as that of the elastic pad 10. The horizontal position of the support frame 2 8 is slightly lower than that of the elastic pad 10. The surface of the support frame 2 8 is provided with a receiving groove 2 9. The surface of the receiving groove 2 9 is slidably connected to the fixing frame 6. When the line card bottom shell 1 is covered on the line card lower cover 2, the elastic pad 10 has a sealing and waterproof effect at the working space of the foot line 16. As time goes by Due to the influence of the environment, the elastic pad 10 may age, deform or lose its elasticity, resulting in a decrease in the waterproof performance between the line card bottom shell 1 and the line card bottom cover 2. At this time, the thickness of the elastic pad 10 becomes thinner. In this process, under the action of the elastic strip 7, the support frame 2 8 has been in contact with the line card bottom shell 1 due to the elastic force of the elastic strip 7, thereby realizing the second sealing barrier between the line card bottom shell 1 and the line card bottom cover 2. When the elastic force of the elastic pad 10 fails, the support frame 2 8 compensates for the sealing and waterproof performance between the line card bottom shell 1 and the line card bottom cover 2.

[0035] Embodiment 2

[0036] The surface of the line card lower cover 2 is movably connected with an elastic pad 10, which is used to ensure the sealing and waterproofness of the connection between the line card bottom shell 1 and the line card lower cover 2. The surface of the elastic pad 10 is provided with a plurality of water absorption holes 11, which facilitates the water at the connection to be discharged into the leakage groove, and then discharged from the line card body along the leakage hole 12.

[0037] A liquid leakage groove 13 is provided on the surface of the wire card lower cover 2 for accommodating the liquid flowing down from the water absorption hole 11. A water leakage hole 12 is provided on the surface of the wire card lower cover 2. The water leakage hole 12 is connected to the liquid leakage groove 13, and the liquid in the water leakage groove is discharged out of the lower card body along the water leakage hole 12.

[0038] The surface of the wire clamp lower cover 2 is fixedly connected with a support frame 14 for fixing a support plate 15. The surface of the support frame 14 is fixedly connected with a support plate 15 for fixing a support foot line 16. The surface of the support plate 15 is movably connected with a foot line 16. The function of the foot line 16 is to transmit current to the bridge wire, so that the bridge wire is heated to ignite the ignition powder, and then the detonator is detonated.

[0039] The surface of the support frame 14 is fixedly connected with a support plate 2 17 for fixing a support busbar 18. The surface of the support plate 2 17 is movably connected with the busbar 18, and its main function is to provide current. The compensation component 3 enhances the sealing between the line card bottom shell 1 and the lower shell, thereby greatly improving the waterproof performance of the line card, which enables the line card to maintain its functionality under various environmental conditions and reduce the performance degradation caused by environmental factors. The busbar 18 is inserted into the wire box from the wiring port 1 20 and the wiring port 2 21, and a spring 22 is also fixedly connected to the line card bottom shell 1.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
