Description

Technical Field

[0001] The utility model relates to the field of surge protectors, in particular to a surge protector which is convenient for wiring. Background Art

[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit. There are many types of surge protectors on the market.

[0003] At present, for example, the model OK-ID100 surge protector produced by Shenzhen Leioli Electronic Technology Co., Ltd. can achieve the purpose of protecting the circuit, but there are still some problems in its use. For example, when wiring the surge protector, the staff needs to unscrew the bolts first, insert the external wiring into the interface of the surge protector after unscrewing, and then tighten the bolts. Although it can achieve the purpose of fixing the wiring, its operation is cumbersome, and when the bolts come into contact with the wiring, it is easy to cause wiring damage, resulting in poor contact. At the same time, the two shells of this surge protector are screwed together by several bolts. During assembly, the staff needs to spend a long time screwing, which wastes the time of the device and has low assembly efficiency. Utility Model Content

[0004] The utility model aims to provide a surge protector which is convenient for wiring, and has the advantages of convenient wiring and convenient assembly.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: it includes a lower shell and an upper shell, a metal connecting block is symmetrically clamped between the lower shell and the upper shell, a graphite sheet is arranged between the two metal connecting blocks, a circuit board is bolted between the two metal connecting blocks, and conductive blocks are welded on the opposite sides of the two metal connecting blocks, a sliding groove is provided on the top of the upper shell, a sliding block is arranged inside the sliding groove, a clamping block is provided on the top of the conductive block, an arc-shaped protrusion is integrally machined on the clamping block, an arc-shaped groove used in conjunction with the arc-shaped protrusion is provided on the sliding block, a limit frame is symmetrically bolted to the front and back sides of the lower shell, an inner groove is provided on the front and back sides of the upper shell, a limit block used in conjunction with the limit frame is arranged inside the inner groove, and an elastic sheet is bolted on the limit block.

[0006] By adopting the above technical scheme, the utility model provides a sliding groove on the upper shell, and when the sliding block inside the sliding groove moves, it will drive the clamping block to move downward. When the external wiring passes through the interfaces at both ends of the protector and enters the inside of the protector, the clamping block can firmly press the external wiring on the conductive block without the need to use bolts to tighten it, thereby improving the wiring speed and preventing wiring damage. By providing an inner groove on the upper shell, when the limit block is pressed to shrink it into the inner groove, the lower shell and the upper shell are buckled, and the two limit frames on the lower shell can be clamped on both sides of the upper shell. After the limit block is loosened, the limit block and the limit frame are clamped with each other, thereby limiting the lower shell and the upper shell of the surge protector, without the need to use bolts, thereby improving the assembly speed.

[0007] The utility model is further configured as follows: the front and back sides of the sliding block are both bolted with sliding blocks, and the interior of the sliding groove is provided with a sliding groove used in conjunction with the sliding block.

[0008] The above technical solution is adopted to limit the sliding block.

[0009] The utility model is further configured as follows: a limiting sliding rod which is integrally processed with the upper shell is slidably connected to the pressing block, and the number of the limiting sliding rods is four.

[0010] The above technical solution is adopted to limit the upward and downward movement of the pressing block.

[0011] The utility model is further configured as follows: a return spring is arranged at the bottom of the pressing block, the number of the return springs is four, and the return spring is sleeved on the surface of the limiting sliding rod.

[0012] The above technical solution is adopted to provide reverse supporting force to the pressing block.

[0013] The utility model is further configured as follows: a guide rod is bolted to the top of the lower shell, the number of the guide rods is four, and a guide groove used in conjunction with the guide rod is opened on the upper shell.

[0014] The above technical solution is adopted to limit the upper shell.

[0015] The utility model is further configured as follows: a partition is arranged between the lower shell and the upper shell, and the partition is used in conjunction with the graphite sheet.

[0016] By adopting the above technical solution, the graphite sheets can be separated conveniently, so that space gaps are formed between different graphite sheets, so as to achieve the purpose of segmented arc extinguishing.

[0017] The utility model is further configured as follows: an insulating bracket is symmetrically bolted between the two metal connecting blocks, and the insulating bracket is used in conjunction with a partition plate and a graphite sheet.

[0018] The above technical solution is adopted to limit and fix the partition and the graphite sheet.

[0019] The utility model is further configured as follows: guide blocks are symmetrically bolted on the limit block, and guide grooves used in conjunction with the guide blocks are provided inside the inner groove.

[0020] The above technical solution is adopted to perform sliding limiting on the limiting block.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The utility model has a sliding groove on the upper shell. When the sliding block inside the sliding groove moves, it will drive the clamping block to move downward. When the external wiring passes through the two end interfaces of the protector and enters the inside of the protector, the clamping block can firmly press the external wiring on the conductive block without the need to tighten with bolts, thereby increasing the wiring speed and preventing wiring pressure loss;

[0023] 2. The utility model has an inner groove on the upper shell. When the limit block is pressed to shrink it into the inner groove, the lower shell and the upper shell are buckled together, and the two limit frames on the lower shell can be clamped on both sides of the upper shell. After the limit block is released, the limit block and the limit frame are engaged with each other, thereby limiting the lower shell and the upper shell of the surge protector without using bolts, thereby improving the assembly speed.
