DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0027] The utility model is further described below in conjunction with embodiments.

[0028] Example: Reference Figure 1-Figure 6 , a wiring insulation protection device, comprising a housing 1, and further comprising:

[0029] In order to enable the device to fix the cable, a fixing component is provided on the device, including a conductive plate 2 slidably arranged inside the shell 1, a second pneumatic rod 12 is provided on one side of the conductive plate 2, a second air guide tube 16 is fixedly installed on one end of the second pneumatic rod 12, a third pneumatic rod 14 is fixedly connected to the end of the second air guide tube 16 away from the second pneumatic rod 12, a clamping plate 7 is fixedly installed on one end of the third pneumatic rod 14, and when the cable squeezes the second pneumatic rod 12, the clamping plate 7 moves, a baffle 11 is fixedly installed on the side of the second pneumatic rod 12 close to the circular capsule 9, a copper plate 5 is fixedly connected to the end of the second pneumatic rod 12 away from the baffle 11, and the copper plate 5 is in contact with the conductive plate 2. Two slide grooves 4 are provided on one side of the sliding plate 3 of the shell 1, and a through hole 18 is provided on one side of the circular capsule 9 of the shell 1.

[0030] By adopting the above technical solution, when the cable is inserted into the shell 1 and is close to the conductive plate 2, the cable squeezes the baffle 11, and the baffle 11 is fixedly installed at one end of the second pneumatic rod 12, so the cable squeezes the second pneumatic rod 12, and the pressure in the second pneumatic rod 12 increases, and the gas enters the third pneumatic rod 14 through the second air duct 16. The pressure of the third pneumatic rod 14 increases, and the clamping plate 7 fixedly installed at one end of the third pneumatic rod 14 moves toward the cable inserted into the shell 1 to clamp the inserted cable, and the conductive plate 2 is in contact with and connected to the copper plate 5, and one end of the copper plate 5 is fixedly connected to the cable. When the cable inserted into the shell 1 contacts the conductive plate 2, a circuit is formed. It is worth noting that the maximum distance moved by the third pneumatic rod 14 cannot push the conductive plate 2, and the material of the second pneumatic rod 12 is plastic.

[0031] In order to prevent the device from leaking electricity, an insulating component is provided on the device, including a sliding plate 3 slidably installed on one side of the shell 1, a circular bag 9 is fixedly installed on the side of the sliding plate 3 close to the second pneumatic rod 12, a first air guide tube 10 is fixedly installed on one side of the circular bag 9, and the end of the first air guide tube 10 away from the circular bag 9 is fixedly connected to the second pneumatic rod 12. When the cable squeezes the second pneumatic rod 12, the circular bag 9 expands, and a limiting ring 8 is fixedly installed on one side of the circular bag 9 of the sliding plate 3, and the limiting ring 8 is arranged around the outer wall of the circular bag 9.

[0032] By adopting the above technical solution, when the second pneumatic rod 12 is squeezed, the air pressure inside it increases, and part of the gas enters the circular bag 9 through the first air duct 10. The gas in the circular bag 9 increases and begins to expand, clamping and wrapping the cables inserted into the shell 1. It is worth noting that part of the cables entering the shell 1 have not had their insulation layer stripped off. A limiting ring 8 is provided on the outer circle of the circular bag 9 to squeeze the circular bag 9 toward the center of the cable, and part of the function of the circular bag 9 is also to clamp the cable.

[0033] In order to prevent the temperature inside the device from rising, a protective component is provided in the device, including an airbag 13 arranged at one end of a third pneumatic rod 14, wherein a volatile liquid is provided in the airbag 13. When the airbag 13 expands when heated, the conductive plate 2 moves, and a fixing plate 17 is fixedly installed at one end of the third pneumatic rod 14. A side of the fixing plate 17 away from the third pneumatic rod 14 is fixedly connected to the airbag 13, and a side of the airbag 13 away from the fixing plate 17 is fixedly connected to the clamping plate 7.

[0034] By adopting the above technical solution, when the current passing through the cable is too large, the cable generates heat to heat the liquid in the airbag 13, and the liquid vaporizes to expand the airbag 13. When the airbag 13 expands, it squeezes the cable, and the cable squeezes the conductive plate 2. The conductive plate 2 moves downward and disconnects from the copper plate 5, so that the circuit is short-circuited to prevent damage to the electrical appliances in the circuit. It is worth noting that the volatile liquid in the airbag 13 is liquid mercury, and the volatilization temperature is 40°-70°.

[0035] Two first gas pressure rods 6 are provided on one side of the conductive plate 2 close to the bottom wall of the shell 1 . One end of the two first gas pressure rods 6 away from the conductive plate 2 is fixedly mounted on the inner bottom wall of the shell 1 . Multiple groups of air outlet holes 19 are provided on both sides of the shell 1 .

[0036] An air outlet valve 15 is disposed at one end of the third air pressure rod 14 away from the clamping plate 7 .

[0037] By adopting the above-mentioned technical solution, when the conductive plate 2 moves downward, the two first pneumatic rods 6 arranged on the inner bottom wall of the shell 1 are squeezed, and the gas in the two first pneumatic rods 6 is blown out from the multiple groups of air outlet holes 19 opened in the shell 1 to cool the interior of the shell 1. It is worth noting that multiple through pipes are arranged inside the shell 1 for connecting the two first pneumatic rods 6 and the multiple groups of air outlet holes 19.

[0038] When the cable needs to be pulled out of the shell 1, the air outlet valve 15 arranged on the shell 1 is pressed, the gas in the third air pressure rod 14 is discharged, the third air pressure rod 14 is reset to the initial position, the clamping of the cable is lost, and the gas in the circular bag 9 is discharged through the first air guide tube 10 and the second air guide tube 16. The circular bag 9 becomes smaller and loses its clamping of the cable, so that the cable can be taken out of the device.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
