[0002] The integrated protection insulation drainage device is a device that can achieve both protection and insulation functions. It is mainly used to protect electrical equipment or systems from external interference and damage while maintaining the normal operation and safety of the equipment. The device integrates different functions together to achieve intelligent and efficient operation of the equipment, greatly improving production efficiency and reducing maintenance costs. The integrated protection insulation drainage device requires the fittings to be connected and fixed to the wires.

Once moisture enters, it will corrode the conductors, damage the interface between the conductors and the conductor sheaths, cause corona, and destroy the stability of the overall quality of the drainage device. However, some hardware sheaths are not currently manufactured as a whole. There are gaps between the assembled structures, and there is a lack of structure to strengthen the connection between the hardware and the sheath. There is a risk of moisture entering, which affects the reliability and safety of the end of the integrated protective insulating drainage device, which is not conducive to the stable operation of the power grid.

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1 A structural schematic diagram of a preferred embodiment of the end moisture-proof structure of the integrated protective insulation drainage device provided by the utility model; Figure 2 It is a structural schematic diagram of the hardware and the connecting block in the utility model; Figure 3 It is a structural schematic diagram of the ferrule in the utility model; Figure 4 This is a schematic diagram of the structure inside the hardware sheath of the utility model; Figure 5 The schematic diagram of the structure inside the hardware in the utility model is an end moisture-proof structure of an integrated protective insulation drainage device, comprising a hardware 1, a wire 2 is arranged inside the hardware 1, a wire sheath 3 is arranged outside the hardware 1 to provide protection for the wire 2; a hardware sheath 4 is arranged outside the hardware 1 to seal and protect the connection between the wire sheath 3 and the wire 2, a reinforcement 5 is arranged outside the hardware sheath 4 to improve the connection strength between the wire sheath 3 and the hardware 1, and an umbrella skirt 6 is arranged outside the hardware sheath 4.

[0023] In the specific implementation process, Figure 1 and Figure 5 As shown, the hardware 1 is square at one end and has a through hole, and is cylindrical at the other end, and the wire 2 is inserted into the hardware 1 .

[0024] It should be noted that: a through hole is provided at one square end of the hardware fitting 1 for installing the hardware fitting 1 , and the inner part of the cylindrical end is hollow for connecting and fixing the wire 2 to the hardware fitting 1 .

[0025] refer to Figure 1 As shown, the wire sheath 3 is arranged on the outside of the wire 2, and one end thereof is abutted against the inside of the hardware 1.

[0026] It should be noted that the wire sheath 3 is used to provide protection for the outer side of the wire 2 to prevent the wire 2 from being subjected to direct friction and mechanical impact. At the same time, the wire 2 is insulated to avoid safety accidents caused by the wire 2 being exposed, and to prevent dirt, chemicals, oxides and other substances from contaminating the outer surface of the wire 2.

[0027] refer to Figure 1 and Figure 5 As shown, the cylindrical portion of the hardware 1 is disposed inside the hardware sheath 4 .

[0028] It should be noted that the hardware sheath 4 covers the connection between the hardware 1 and the wire 2 to provide protection for the connection, prevent the connection between the wire 2 and the hardware 1 from being contaminated by the outside, and fix the wire 2 on the hardware 1 to prevent the wire 2 from falling off the hardware 1.

[0029] refer to Figure 3 and Figure 4 As shown, the reinforcement 5 includes a connection block 501 arranged outside the hardware 1, and a clamping sleeve 502 adapted to the connection block 501 is arranged outside the hardware sheath 4. A clamping groove 8 is opened inside the connection block 501, and a clamping ring 7 is fixedly connected inside the clamping sleeve 502.

[0030] It should be noted that when the hardware sheath 4 is connected to the hardware 1, the clamping sleeve 502 on the hardware sheath 4 is clamped to the outside of the connecting block 501 on the hardware sheath 4, and the hardware sheath 4 is squeezed to improve the connection strength between the hardware sheath 4 and the hardware 1, and at the same time improve the sealing between the hardware sheath 4 and the hardware 1, effectively improving the moisture-proof effect. When the clamping sleeve 502 is clamped to the outside of the connecting block 501, the clamping ring 7 is simultaneously clamped into the inside of the clamping groove 8, which improves the connection strength between the hardware sheath 4 and the hardware 1 and prevents the hardware sheath 4 from falling off.

[0031] The working principle of the end moisture-proof structure of the integrated protective insulation drainage device provided by the utility model is as follows:

[0032] First, extrude the conductor sheath 3, then form the umbrella skirt 6, and at the same time insert the conductor sheath 3 into the interior of the hardware, and finally inject or mold the hardware sheath 4 as a whole. A reinforcement piece 5 is added at the interface of the hardware 1, the conductor 2 and the conductor sheath 3, and the hardware sheath is molded under high temperature and high pressure to make all interfaces become one. This structure increases the path and difficulty of moisture entry, so that the end of the integrated protective insulation drainage device has a good moisture-proof function, thereby making the product quality more reliable and safe, which is conducive to the stable operation of the power grid. The hardware sheath 4 is used to cover the connection between the hardware 1 and the conductor 2 inside to provide protection for the connection and prevent the connection between the conductor 2 and the hardware 1 from being polluted by the outside. At the same time, the conductor 2 is fixed on the hardware 1 to prevent the conductor 2 from falling off the hardware 1. When the hardware sheath 4 is connected to the hardware 1, the sleeve 502 on the hardware sheath 4 is clamped to the hardware The outside of the connecting block 501 on the tool sleeve 4 squeezes the hardware sleeve 4 to improve the connection strength between the hardware sleeve 4 and the hardware 1, and at the same time improves the sealing between the hardware sleeve 4 and the hardware 1, effectively improving the moisture-proof effect. When the ferrule 502 is clamped to the outside of the connecting block 501, the clamping ring 7 is simultaneously clamped into the inside of the clamping groove 8 to improve the connection strength between the hardware sleeve 4 and the hardware 1 and prevent the hardware sleeve 4 from falling off. It should be noted that when forming the hardware sleeve 4 on the surface of the hardware, a layer of coupling agent is applied on the surface of the hardware 1. The coupling agent can not only make the surface of the hardware 1 and the hardware sleeve 4 firmly bonded; at the same time, the hardware sleeve can also be firmly bonded to the original rubber sleeve, thereby forming a closed whole to achieve a moisture-proof effect.
