Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a device for preventing a fuse core from vibrating and falling off. Background Art

[0002] A fuse is an electrical device that generates heat to melt the fuse and disconnect the circuit when the current exceeds the specified value. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. Fuses are generally composed of a fusible core and a mounting base. The fusible core is generally cylindrical and is one of the most commonly used protective devices.

[0003] In the related art, fuses are used as short-circuit and overcurrent protectors in various circuits or circuit equipment. However, when fuses are used in circuit equipment subject to strong vibration, the strong vibration of the equipment itself may cause the fuse core to loosen or even fall off, resulting in failure of the connection between the fuse core and the circuit equipment or overheating of the equipment due to a short circuit, causing the fuse to lose its overcurrent protection function and cause safety hazards such as fire. Utility Model Content

[0004] The utility model aims to provide a device for preventing a fuse core from falling off due to vibration, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for preventing a fuse core from vibrating and falling off is symmetrically arranged at both ends of the fuse core, comprising:

[0007] A wiring board, one end of which is provided with a fixing clamp for clamping the end of the fuse;

[0008] Through holes are correspondingly arranged on both sides of the top of the fixing clamp, and pins are passed through the through holes on both sides;

[0009] The wiring board is provided with a baffle, and the baffle abuts against the end of the fuse.

[0010] According to this solution, at least the following technical effects are achieved:

[0011] The device for preventing the fuse core from vibrating and falling off is symmetrically arranged at both ends of the fuse core, by arranging a fixing clip at one end of the wiring board to clamp the end of the fuse core, and arranging pins in the through holes on both sides of the top of the fixing clip, and at the same time arranging a baffle on the wiring board, the baffle abuts against the end of the fuse core, and ensures that the fuse core is fixed by the device in the horizontal, longitudinal and vertical directions, so that the connection between the fuse and the circuit is more stable, and the fuse core of the fuse is prevented from loosening or falling off due to strong vibration, resulting in failure of the connection between the fuse core and the circuit equipment, or the equipment is overheated due to a short circuit, causing the fuse to lose its overcurrent protection function and cause fire and other safety hazards. The device can effectively fix the fuse core under strong vibration, so that it maintains effective circuit contact, ensures the current protection function of the fuse, and improves the reliability of the fuse and the safety of the equipment.

[0012] As a further solution of the utility model: a first threaded hole is arranged at the bottom of the fixing clamp, a second threaded hole is correspondingly arranged on the wiring board, and the first threaded hole is connected to the second threaded hole by bolts.

[0013] Since a first threaded hole is provided at the bottom of the fixing clamp and a second threaded hole is correspondingly provided on the terminal board, the first threaded hole and the second threaded hole are connected by bolts, so that the connection between the fixing clamp and the terminal board is more stable, ensuring that the fuse core maintains longitudinal stability in the fixing clamps at both ends. At the same time, the fixing clamp can be easily maintained and replaced through the bolt connection, which reduces the time for maintenance and replacement and improves work efficiency.

[0014] As a further solution of the utility model: the baffle is L-shaped.

[0015] As a further solution of the utility model: the longitudinal side of the L-shaped baffle is in contact with the end of the fuse core, and the lateral side of the L-shaped baffle is connected to the wiring board.

[0016] Since the longitudinal side of the L-shaped baffle abuts against the end of the fusible core and the lateral side of the L-shaped baffle is connected to the terminal block, the stability of the baffle is enhanced. Furthermore, since the device is symmetrically arranged, the two ends of the fusible core abut between the longitudinal sides of the baffles at both ends, ensuring that the fusible core maintains lateral stability between the longitudinal sides of the baffles at both ends.

[0017] As a further solution of the utility model: a third threaded hole is arranged on the lateral side of the L-shaped baffle, a fourth threaded hole is correspondingly arranged on the wiring board, and the third threaded hole is connected to the fourth threaded hole by bolts.

[0018] By arranging a third threaded hole on the lateral side of the L-shaped baffle, a fourth threaded hole is correspondingly arranged on the terminal board, and the third threaded hole and the fourth threaded hole are connected by bolts, the stability of the baffle is further enhanced, and the two ends of the fuse core are prevented from hitting the longitudinal sides of the baffles at both ends due to lateral vibration, causing the baffles to loosen or move, thereby further improving the lateral stability of the fuse core between the longitudinal sides of the baffles at both ends; at the same time, the baffle can be easily maintained and replaced through the bolt connection, which reduces the time for maintenance and replacement and improves work efficiency.

[0019] As a further solution of the utility model: bending parts are respectively provided at both ends of the pin shaft.

[0020] By respectively arranging bending parts at both ends of the pin shaft, it is ensured that after the pin shaft passes through the through holes on both sides, the top of the fixing clamp is locked by the bending parts at both ends of the pin shaft, so that the two ends of the fuse core are completely locked in the fixing clamps at both ends, ensuring that the fuse core is fastened in the fixing clamp by the pin shaft to maintain its vertical stability.

[0034] like Figure 1-4 The embodiment of the utility model shown is a device for preventing the fuse core from vibrating and falling off, which is symmetrically arranged at both ends of the fuse core 101, and is characterized in that it includes: a terminal block 102, one end of which is provided with a fixing clamp 103 to clamp the end of the fuse core 101; through holes 104 are respectively provided on both sides of the top of the fixing clamp 103, and pins 105 are passed through the through holes 104 on both sides; a baffle 106 is provided on the terminal block 102, and the baffle 106 abuts against the end of the fuse core 101.

[0035] Specifically, the device for preventing the fuse core from falling off due to vibration is symmetrically arranged at both ends of the fuse core, by arranging a fixing clip 103 at one end of the wiring board 102, clamping the end of the fuse core 101, and arranging a pin 105 in the through holes 104 on both sides of the top of the fixing clip 103, and at the same time arranging a baffle 106 on the wiring board 102, the baffle 106 abuts against the end of the fuse core 101, ensuring that the fuse core 101 is fixed by the device in the horizontal, longitudinal and vertical directions, so that the connection between the fuse and the circuit is more stable, and the fuse core 101 of the fuse is prevented from loosening or falling off due to strong vibration, resulting in failure of the connection between the fuse core 101 and the circuit equipment or the equipment is overheated due to a short circuit, causing the fuse to lose its overcurrent protection function and cause fire and other safety hazards. The device can effectively fix the fuse core 101 of the fuse under strong vibration, so that it maintains effective circuit contact, ensures the current protection function of the fuse, and improves the reliability of the fuse and the safety of the equipment.
