Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, specifically a surge protector that is easy to replace with a chip. Background Technology

[0002] A surge protector is a device that provides safety protection for electronic equipment. It is primarily used to limit transient overvoltages (surges) and discharge surge current to ground, thereby protecting the equipment from damage. Its core components are nonlinear elements, such as varistors and gas discharge tubes. Under normal conditions, they exhibit high resistance and do not affect circuit operation; when a surge occurs, they quickly switch to a low-resistance state, clamping the voltage to a safe level. They are widely used in power, communications, and data center fields to prevent overvoltages caused by lightning, power grid operations, etc., from leading to equipment damage, data loss, or fire risks.

[0003] Utility model patent CN221614645U discloses a surge protector, which comprises a sliding rail, a protector body slidably connected to the outside of the sliding rail, a connecting box fixedly connected to the bottom of the protector body, a limit mechanism inside the connecting box, a torsion mechanism on one side of the limit mechanism, and a connecting plate fixedly connected to the inner wall of the connecting box. A fixing groove is fixedly connected to the top of the connecting plate, and a slider is slidably connected to the inner wall of the fixing groove. Through the limit mechanism, the top of the limit plate can be tightly fitted to one side of the sliding rail. Simultaneously, the anti-slip texture on the top of the limit plate enhances the friction between the limit plate and the sliding rail, further improving the stability of the protector body. This prevents the protector body from easily loosening or shifting during operation, improving the protection effect and reducing the risk of equipment damage.

[0004] However, during use, the surge protector body is highly integrated and difficult to disassemble. Therefore, when a protection unit in a certain path is damaged, it cannot be easily disassembled and replaced. It is difficult to easily replace the damaged protection unit to ensure that the entire protector can continue to work normally. In addition, the installation of the surge protector is relatively cumbersome. It is necessary to insert the protector body from the end of the sliding rail and slide it to the designated position, and then operate the limiting mechanism to fix the position of the protector. The operation is inconvenient, especially when there are several surge protectors on the sliding rail, the disassembly of the middle surge protector becomes very troublesome. Therefore, in order to solve the above problems, a surge protector that is easy to replace the chip is proposed. Utility Model Content

[0005] To address the technical problems of difficulty in conveniently disassembling and replacing damaged or malfunctioning components in surge protectors during use, and the cumbersome operation of installing and disassembling the surge protector as a whole, this utility model provides a surge protector that facilitates chip replacement.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A surge protector with easy chip replacement includes a pluggable mounting base and a protector body, wherein the protector body is plugged into the pluggable mounting base; the protector body includes a housing and a front cover, and a protection component is installed in the housing; the housing and the front cover are snap-fitted together, wherein the housing and the front cover are respectively provided with a rear connecting lug and a front connecting lug, and are bolted together; the protection component includes a main output terminal, on which several sets of independent protection units are attached, and the main output terminal is electrically connected to an output connector; each protection unit consists of a set of protection chips and a set of tripping components, both of which are snap-fitted into the housing.

[0008] In one possible implementation, a ring of splicing grooves is formed on the side of the opening of the outer shell, and a number of evenly arranged buckles are provided in the splicing grooves. A number of snap holes corresponding to the buckles are provided at the opening of the front cover.

[0009] In one possible implementation, the pluggable mounting base includes a back plate with a support plate fixedly disposed at its bottom. The back plate has several bolt countersunk holes, through which the pluggable mounting base is fixed to the existing structure.

[0010] In one possible implementation, the bottom and top of the back plate are respectively fixedly provided with symmetrically arranged anti-detachment plug blocks and receiving plates. The back of the outer shell is machined to form a plug groove and a plug connector, and the plug groove is provided with an anti-detachment groove. The anti-detachment plug block is plugged into the plug groove, and the plug connector is plugged into the receiving plate.

[0011] In one possible implementation, the anti-detachment plug includes a cylindrical shell with a guide plate fixedly disposed inside and movable locking plates slidably disposed on both sides thereon. The two ends of the movable locking plates are in sliding contact with the guide plate, and a return spring is disposed between the movable locking plates and the guide plate.

[0012] In one possible implementation, the two ends of the housing are respectively machined to form an inlet end seat and an outlet end seat, and a support plate that contacts the front cover is provided between the inlet end seat and the outlet end seat.

[0013] In one possible implementation, the protection chip includes a resistor sheet with electrically connected conductive patch one and conductive patch two bonded to its two ends, wherein conductive patch one is electrically connected to the main outlet terminal.

[0014] In one possible implementation, the tripping assembly includes a fixed insert that snaps into the inlet terminal block, with an inlet connector and a tripping spring connected to its two ends respectively. The tripping spring has a through groove that snaps into the conductive patch two. After the tripping spring is bent to connect the through groove with the conductive patch two, the tripping spring and the conductive patch two are fixedly connected by soldering.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] Since the protector body is assembled from the outer shell and the front cover by snaps and holes, the two can be easily separated during disassembly. Inside the outer shell, the protection components consist of several independent protection units, and each protection unit is composed of a protection chip and a tripping component. Therefore, if any part of the outgoing terminal block, protection chip, or tripping component in the outer shell is damaged, it can be replaced individually. The operation is very convenient; it only requires removing and reassembling the corresponding part, which can significantly improve maintenance efficiency.

[0017] In addition, the protector body can be simply inserted downwards into the plug-in mounting base during installation, and can be removed by simply lifting it upwards. This connection method makes installation and removal very simple and easy, which can significantly improve maintenance efficiency. Furthermore, since the anti-detachment plug block on the plug-in mounting base can generate a certain pull-out resistance by snapping when inserted into the plug slot, it can ensure the stability of the protector body after installation and prevent it from falling off the plug-in mounting base.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 3 As shown, this embodiment provides a surge protector that facilitates chip replacement, including a pluggable mounting base 1 and a protector body. The protector body is plugged into the pluggable mounting base 1. The protector body includes a housing 2 and a front cover 3, and a protection component 4 is installed in the housing 2. The housing 2 and the front cover 3 are snap-fitted together. The housing 2 and the front cover 3 are respectively provided with a rear connecting lug 23 and a front connecting lug 32, which are bolted together. The protection component 4 includes a terminal busbar 41, on which several sets of independent protection units 43 are attached. The terminal busbar 41 is electrically connected to a terminal connector 42. The protection unit 43 consists of a set of protection chips and a set of tripping components. The protection chips and tripping components are snap-fitted into the housing 2.

[0028] In addition, a ring of splicing grooves 21 is provided on the side of the opening of the outer shell 2, and several evenly arranged buckles 22 are provided in the splicing grooves 21. Several buckle holes 31 corresponding to the buckles 22 are provided at the opening of the front cover 3.

[0029] Based on the above structural scheme, since the protector body is assembled from the outer shell 2 and the front cover 3 by the snap 22 and the snap hole 31, the two can be easily separated during disassembly. Inside the outer shell 2, the protective component 4 consists of several independent protective units 43, and the protective unit 43 is also composed of a set of protective chips and tripping components. Therefore, when any part of the outgoing terminal busbar 41, the protective chip and the tripping component in the outer shell 2 is damaged, it can be replaced individually, and the operation is very convenient. It is only necessary to remove the corresponding part and reassemble it, which can significantly improve maintenance efficiency.

[0030] To enable quick installation and removal of the protector body, such as Figure 4 - Figure 5 As shown, the pluggable mounting base 1 includes a back plate 11, with a support plate 12 fixedly mounted on its bottom. The back plate 11 has several countersunk bolt holes 13, through which the pluggable mounting base 1 is fixed to the existing structure. This structural design allows the protector body to be supported by the support plate 12 and the back plate 11, while the countersunk bolt holes 13 facilitate the installation of the pluggable mounting base 1 in a designated position on the existing structure without causing the bolts to protrude. Simultaneously, symmetrically arranged anti-detachment pluggable blocks are fixedly mounted on the bottom and top of the back plate 11. The back of the housing 2 is machined with a plug groove 27 and a plug connector 28, and the plug groove 27 is provided with an anti-detachment groove 271. The anti-detachment plug block 15 is plugged into the plug groove 27, and the plug connector 28 is plugged into the housing 14. Based on the above connection scheme, the protector body can be installed by simply inserting it downwards into the plug-in fixing seat 1, and can be removed from the plug-in fixing seat 1 by simply lifting it upwards. This connection method makes installation and removal very simple and easy, and can significantly improve maintenance efficiency.

[0031] Based on the above solution, to prevent the protector body installed on the pluggable mounting base 1 from accidentally falling off, the pluggable mounting base 1 needs to provide a certain pull-out resistance to prevent falling off. Therefore, if Figure 6 As shown, the anti-detachment plug-in block 15 includes a cylindrical shell 151, inside which a guide plate 152 is fixedly installed, and movable locking plates 153 are slidably installed on both sides. The two ends of the movable locking plates 153 are in slidable contact with the guide plate 152, and a return spring 154 is provided between the movable locking plates 153 and the guide plate 152. Based on the above structural scheme, when the cylindrical shell 151 is inserted into the plug-in groove 27, the movable locking plates 153 will be pushed by the force to overcome the push of the return spring 154 and slide inward, so that the cylindrical shell 151 can be inserted smoothly. After the cylindrical shell 151 is fully inserted, the movable locking plates 153 will slide outward under the push of the return spring 154 and lock into the anti-detachment groove 271, thereby providing anti-pull-out force and preventing the protector body from easily falling off after installation.

[0032] like Figure 2 As shown, the two ends of the outer casing 2 are respectively machined to form an inlet terminal 25 and an outlet terminal 26, and a support plate 24 that contacts the front cover 3 is provided between the inlet terminal 25 and the outlet terminal 26. The above structure provides the necessary structural foundation for the installation of the protection chip and the tripping assembly, and the support plate 24 can provide support for the front cover 3 to prevent it from deforming during use.

[0033] like Figure 3 As shown, the protection chip includes a resistor 431, with conductive patches 432 and 433 electrically connected to its two ends respectively. The conductive patch 432 is electrically connected to the output terminal busbar 41. A circuit can be formed through the conductive patches 432 and 433 to connect the resistor 431 into the circuit, so that it can perform its function.

[0034] like Figure 3 As shown, the tripping assembly includes a fixed insert 434 that snaps into the inlet terminal block 25. Both ends of the insert are electrically connected to an inlet connector 435 and a tripping spring 436, respectively. The tripping spring 436 has a through groove that engages with a conductive patch 433. After bending the tripping spring 436 to connect the through groove with the conductive patch 433, the tripping spring 436 and the conductive patch 433 are fixedly connected by soldering. This connection method enables the installation of the tripping spring 436 and the electrical connection between the tripping spring 436 and the resistor 431. When a surge occurs, the resistance of the resistor 431 drops sharply, generating a large amount of heat, causing the solder to detach. At this time, the tripping spring 436 will spring up under its own elastic force, cutting off the circuit.

[0035] The working principle and usage process of this utility model:

[0036] When installing the protector body, simply insert it downwards into the plug-in mounting base 1. When disassembling, simply lift it upwards to remove it from the plug-in mounting base 1. This connection method makes installation and disassembly very simple and easy, which can significantly improve maintenance efficiency. Specifically, when inserting the protector body so that the shell 151 is inserted into the insertion slot 27, the movable locking plate 153 is pushed by the force to overcome the push of the return spring 154 and slide inwards, so that the shell 151 can be inserted smoothly. After the shell 151 is fully inserted, the movable locking plate 153 will slide outwards under the push of the return spring 154 and lock into the anti-disengagement slot 271, thereby providing anti-pull-out force and preventing the protector body from easily falling off after installation.

[0037] In addition, the protector body is assembled from the outer shell 2 and the front cover 3 by the snap fastener 22 and the snap hole 31, so the two can be easily separated during disassembly. Inside the outer shell 2, the protection component 4 consists of several independent protection units 43, and the protection unit 43 is also composed of a protection chip and a tripping component. Therefore, when any part of the outgoing terminal busbar 41, the protection chip and the tripping component in the outer shell 2 is damaged, it can be replaced individually. The operation is very convenient. It only requires the corresponding part to be removed and reassembled, which can significantly improve maintenance efficiency.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
