[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] First, refer to Figure 1 and Figure 4 , the safety clip fixing device provided by the utility model is now described. The safety clip 4 is usually installed on the upper cover 100 of the fuse box, and the safety clip fixing device fixes the safety clip 4 on the upper cover 100. The safety clip 4 fixing device includes a positioning member 1, a first fixing mechanism 2 and a second fixing mechanism 3. The positioning member 1, the first fixing mechanism 2 and the second positioning mechanism are arranged on the upper cover 100. The positioning member 1 is used to provide guidance and limit the position of the safety clip 4 when installing the safety clip 4, and the positioning member 1 is arranged on the upper cover 100. A positioning hole is provided in the middle position of the safety clip 4. When installing the safety clip 4, the safety clip 4 is sleeved on the positioning member 1 through the positioning hole. Thereafter, one side of the safety clip 4 is fixed by the first fixing mechanism 2, and the other side of the safety clip 4 is fixed by the second fixing mechanism 3.

[0034] Compared with the prior art, the safety clip fixing device provided by the utility model locates the position of the treasure box clip through the positioning member 1, fixes one side of the safety clip 4 through the first fixing mechanism 2, and fixes the other side of the safety clip 4 through the second fixing mechanism 3. The safety clip 4 is fixed by the first fixing mechanism 2 and the second fixing mechanism 3, and the first fixing mechanism 2 and the second fixing mechanism 3 cooperate to improve the holding force of the safety clip 4 and prevent the safety clip 4 from falling off.

[0035] Reference Figure 1 Optionally, the fuse clip 4 includes a pluggable slow-blow fuse part 41, a pluggable fast-blow fuse part 42, and a third connection part 43. The third connection part 43 is arranged between the pluggable slow-blow fuse part 41 and the pluggable fast-blow fuse part 42, and one side of the third connection part 43 is connected to the pluggable slow-blow fuse part 41, and the other side is connected to the pluggable fast-blow fuse part 42. The pluggable fast-blow fuse part 42 is installed by plugging and unplugging the fast-blow fuse, and the pluggable slow-blow fuse part 41 is installed by plugging and unplugging the slow-blow fuse.

[0036] Fast-blow fuses are fuses that blow quickly. When an overcurrent occurs in a circuit, the fast-blow fuse will blow in a relatively short time, thereby cutting off the circuit and protecting the electrical system. Fast-blow fuses are usually used for short-circuit protection in circuits. They can cut off the circuit in a short time to prevent the wires and other components in the circuit from being damaged by overcurrent.

[0037] Slow-blow fuses are a special type of electrical protection element, often used in circuits to prevent fire and equipment damage caused by excessive current. The parameters of slow-blow fuses are usually that the fuse cannot be disconnected within 4 hours when 100% current passes through the fuse, and the fuse must be disconnected within 60 seconds when 200% current passes through the fuse. The fully blown fuse also has a parameter that the fuse cannot be disconnected within 30 milliseconds when 1000% current passes through the fuse.

[0038] The time-delay characteristic of slow-blow fuses is that they remain intact when non-fault pulse currents appear in the circuit, and they can provide protection against long-term overloads. In some circuits, the current at the moment of switching is several times greater than the normal operating current. Although the peak value of this current is very high, it appears for a very short time. It is usually called pulse current, impact current, or surge current. Ordinary fuses cannot withstand this current. If ordinary fuses are used in such circuits, they will not work properly. If larger fuses are used, they will not be protected when the circuit is overloaded. The fuse of slow-blow fuses is specially processed, and it has the function of absorbing energy. Adjusting the amount of energy absorption can make it able to withstand impact currents and provide protection against overloads.

[0039] Slow-blow fuses have the following characteristics: When an abnormal overload current appears in the circuit, the slow-blow fuse can be blown in time to cut off the current and effectively protect the safety of the circuit and equipment. Compared with fast-acting fuses, slow-blow fuses have a longer blowing time. They can gradually absorb overload current in the circuit and avoid the generation of instantaneous large currents. Due to their special fusing characteristics, slow-blow fuses will not be blown by mistake due to surge current or pulse current in the circuit, effectively avoiding misoperation and damage to the equipment. After the slow-blow fuse is blown, the normal operation of the circuit can be restored by replacing a new fuse, which has good reusability.

[0040] Slow-blow fuses have the following functions: In a circuit, due to equipment failure, abnormal operation, etc., overload current may occur, causing fire and equipment damage. At this time, the slow-blow fuse can be blown in time to effectively protect the safety of the circuit and equipment. The slow-blow fuse can limit the current in the circuit to prevent damage to the circuit and equipment due to surge current or pulse current. In a circuit, if the voltage rises abnormally due to equipment failure, the slow-blow fuse can be blown in time to cut off the power supply, thereby avoiding electric shock accidents.

[0041] Optionally, the positioning hole is provided on the third connecting portion 43. The positioning member 1 is a hollow cylindrical shape. The material of the positioning member 1 can be the same as that of the upper cover 100, and the two are integrally formed by an injection molding process. The material of the positioning member 1 can also be different from that of the upper cover 100, and the two are connected together by bonding or welding. A chamfer is provided at the end of the positioning member 1, and the outer diameter of the positioning member 1 is smaller than the diameter of the positioning hole, so that when the safety clip 4 is installed, it is convenient to put the safety clip 4 on the positioning member 1 through the positioning hole.

[0042] Optionally, a through slot communicating with the positioning hole is provided in the middle of the third connecting portion 43, and a circle of reinforcing ribs are provided on the inner walls of the through slot and the positioning slot. The through slot is used to reduce the overall weight of the safety clip 4, so as to reduce the holding force required to fix the safety clip 4 and improve the stability of the safety clip 4. The reinforcing ribs are used to improve the structural strength of the third connecting portion 43. The width of the plug-in slow-blow type safety portion 41 is greater than that of the plug-in fast-blow type safety portion 42, and the overall shape of the safety clip 4 is Y-shaped.

[0043] Reference Figure 1 and 2, the first fixing mechanism 2 is arranged on one side of the plug-in slow-blow type insurance part 41. The first fixing mechanism 2 includes two first hooks.

The head of the first hook portion 22 is provided with a rounded corner. In the process of inserting the plug-in slow-blow type insurance into the two first hooks, the rounded corner of the first hook portion 22 can reduce the resistance of inserting the plug-in slow-blow type insurance portion 41. When the plug-in slow-blow type insurance portion 41 completely enters between the first connection portions 21, since the spacing between the first hook portions 22 is less than the width of the plug-in slow-blow type insurance portion 41, the first hook portion 22 interferes with the plug-in slow-blow type insurance portion 41, so that the first hook portion 22 fixes the plug-in slow-blow type insurance portion 41.

[0045] The opposite sides of the two first connection parts 21 are planes, and the distance between the two first connection parts 21 is larger than the plug-in slow-blow type insurance part 41 , so as to avoid interference between the plug-in slow-blow type insurance part 41 and the first connection part 21 .
