DETAILED DESCRIPTION

[0022] 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.

[0023] like Figures 1 to 6 As shown, the utility model provides an electrical fire-proof current-limiting protector, comprising a housing 1 and a mounting housing 2, wherein the mounting housing 2 is fixedly sleeved on the upper portion of the housing 1;

[0024] An electrical fire-proof current-limiting protector 4 is movably installed on one side of the interior of the shell 1, and a connecting frame 5 is fixedly installed on the upper and lower sides of the electrical fire-proof current-limiting protector 4. A connecting rod 6 is rotatably sleeved on the top of the connecting frame 5. A rectangular groove 18 is opened at the rear of the interior of the shell 1, and a rectangular groove 29 is opened at the rear of the interior of the shell 1. The rectangular groove 29 is located behind the rectangular groove 18. A cylindrical groove 2 11 is opened at the rear of the interior of the shell 1. The cylindrical groove 2 11 is located behind the rectangular groove 2 9. A cylindrical groove 10 is opened at the rear of the interior of the shell 1. The cylindrical groove 10 is located behind the cylindrical groove 2 11. A fixing plate 7 is fixedly installed at the end of the connecting rod 6, and a spring 13 is fixedly installed on one side of the interior of the cylindrical groove 2 11. A top plate 14 is fixedly installed on one end of the spring 13. A limiting rod 12 is fixedly installed at the rear of the top plate 14, and one end of the limiting rod 12 extends to the interior of the cylindrical groove 10.

[0025] When the staff uses it, they first press the connecting rod 6 from behind. When the connecting rod 6 moves backward, it will drive the fixed plate 7 to move backward. When the fixed plate 7 moves backward, it will drive the rectangular slot 29 to move backward. When the rectangular slot 29 moves backward, the spring 13 will be compressed. When the spring 13 is compressed, it will drive the limiting rod 12 to move toward the inside of the cylindrical slot 10. When the fixed plate 7 moves from the inside of the rectangular slot 29 to the inside of the cylindrical slot 211, at this time, by rotating the connecting rod 6 ninety degrees, when the connecting rod 6 is rotated ninety degrees, the fixed plate 7 will be rotated ninety degrees. The spring 13 will drag the fixed plate 7 to the inside of the rectangular slot 8 due to its elasticity. At this time, the electrical fire-proof current limiting protector 4 can be removed.

[0026] By pressing the connecting rod 6 backward, when the connecting rod 6 moves backward, it will drive the fixing plate 7 to move backward. When the fixing plate 7 moves to the inside of the cylindrical groove 11, the connecting rod 6 can be rotated ninety degrees and then moved forward to remove the electrical fire-proof current-limiting protector 4. Compared with the traditional device, the device can quickly install the electrical fire-proof current-limiting protector 4, thereby avoiding the influence of long-term twisting of the bolts and the stripping of the belt, and at the same time improves the working efficiency of the device and speeds up the installation of the electrical fire-proof current-limiting protector 4.

[0027] Among them, silicon mud layers 15 are fixedly installed on the left and right sides of the electrical fire-proof current-limiting protector 4, a copper sheet 16 is fixedly installed on one side of the silicon mud layer 15, a graphite sheet 17 is fixedly installed on one side of the copper sheet 16, and an aluminum sheet 18 is fixedly installed on one side of the graphite sheet 17.

[0028] When the electrical fire-proof current-limiting protector 4 is in use, heat will be generated. When the electrical fire-proof current-limiting protector 4 generates heat, the heat will be dissipated through the outer shell of the electrical fire-proof current-limiting protector 4. The silicon mud layer 15 will evenly disperse the heat on the surface of the electrical fire-proof current-limiting protector 4 to the surface of the copper sheet 16. When the heat contacts the surface of the copper sheet 16, the copper sheet 16 will weaken the heat, and the remaining heat will reach the surface of the graphite sheet 17. The graphite sheet 17 will weaken the heat, and the remaining heat will reach the surface of the aluminum sheet 18, and part of the heat will be eliminated through the aluminum sheet 18.

[0029] The heat emitted by the electrical fire-proof current-limiting protector 4 is evenly distributed on the surface of the copper sheet 16 through the silicon mud layer 15, and then the heat inside the electrical fire-proof current-limiting protector 4 is dissipated and weakened faster through the cooperation between the copper sheet 16, the graphite sheet 17 and the aluminum sheet 18. Compared with the traditional device, the device quickly dissipates and weakens the heat generated inside the electrical fire-proof current-limiting protector 4, thereby avoiding excessive heat inside the electrical fire-proof current-limiting protector 4 and damage to components, thereby accelerating the dissipation of heat inside the electrical fire-proof current-limiting protector 4.

[0030] A protection door 3 is hingedly installed on the front of the shell 1, and the bottom of the protection door 3 is movably connected to the shell 1.

[0031] The protection door 3 can be used to protect the electrical fire-proof current-limiting protector 4 inside the housing 1 , thereby reducing dust from entering the housing 1 and affecting the electrical fire-proof current-limiting protector 4 .

[0032] Among them, an operating light 19 and a communication light 20 are fixedly installed on the front of the electrical fire-proof current-limiting protector 4 , and the communication light 20 is located on the right side of the operating light 19 .

[0033] When the operation light 19 is on, the electrical fire-proof current-limiting protector 4 operates normally, so that it is convenient to observe the normal working condition of the electrical fire-proof current-limiting protector 4.

[0034] Among them, an overload warning light 21, a short circuit warning light 22 and a fault warning light 23 are fixedly installed on the front of the electrical fire-proof current limiting protector 4. The overload warning light 21 is located on the right side of the communication light 20, the short circuit warning light 22 is located on the right side of the overload warning light 21, and the fault warning light 23 is located on one side of the short circuit warning light 22.

[0035] When the overload warning light 21 is on, the electrical fire-proof current-limiting protector 4 is overloaded during operation; when the short-circuit warning light 22 is on, the electrical fire-proof current-limiting protector 4 is short-circuited; when the fault warning light 23 is on, the electrical fire-proof current-limiting protector 4 is malfunctioning.

[0036] Among them, the rectangular groove 1 8 , the rectangular groove 2 9 , the cylindrical groove 1 10 and the cylindrical groove 2 11 are all located on one side of the interior of the shell 1 , and the rectangular groove 1 8 , the rectangular groove 2 9 , the cylindrical groove 1 10 and the cylindrical groove 2 11 are interconnected.

[0037] The interiors of the rectangular groove 1 8 , the rectangular groove 2 9 and the cylindrical groove 2 11 are interconnected, so that the fixing plate 7 can move inside the rectangular groove 1 8 , the rectangular groove 2 9 and the cylindrical groove 2 11 .

[0038] The working principle and use process of this utility model:

[0039] When the staff uses it, they first press the connecting rod 6 from behind. When the connecting rod 6 moves backward, it will drive the fixed plate 7 to move backward. When the fixed plate 7 moves backward, it will drive the rectangular slot 29 to move backward. When the rectangular slot 29 moves backward, the spring 13 will be compressed. When the spring 13 is compressed, it will drive the limiting rod 12 to move toward the inside of the cylindrical slot 10. When the fixed plate 7 moves from the inside of the rectangular slot 29 to the inside of the cylindrical slot 211, at this time, by rotating the connecting rod 6 ninety degrees, when the connecting rod 6 is rotated ninety degrees, the fixed plate 7 will be rotated ninety degrees. The spring 13 will drag the fixed plate 7 to the inside of the rectangular slot 8 due to its elasticity. At this time, the electrical fire-proof current limiting protector 4 can be removed.

[0040] When the electrical fire-proof current-limiting protector 4 is in use, heat will be generated. When the electrical fire-proof current-limiting protector 4 generates heat, the heat will be dissipated through the outer shell of the electrical fire-proof current-limiting protector 4. The silicon mud layer 15 will evenly disperse the heat on the surface of the electrical fire-proof current-limiting protector 4 to the surface of the copper sheet 16. When the heat contacts the surface of the copper sheet 16, the copper sheet 16 will weaken the heat, and the remaining heat will reach the surface of the graphite sheet 17. The graphite sheet 17 will weaken the heat, and the remaining heat will reach the surface of the aluminum sheet 18, and part of the heat will be eliminated through the aluminum sheet 18.
