Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, specifically a surge protector with overcurrent protection. Background Technology

[0002] Surge protectors, also known as lightning arresters, are electronic devices that provide safety protection for various electronic equipment, instruments, and communication lines. When a surge current or voltage spike suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in a very short time, thereby preventing damage to other equipment in the circuit. Surge protectors play a role in overcurrent protection. A surge protector mainly consists of a protector mounting base and several sets of protector bodies installed on the protector base. The protector bodies achieve the purpose of overcurrent protection for circuit equipment.

[0003] However, existing surge protectors have the following problems during use: To facilitate replacement of the protector body, it is usually installed by directly plugging it into the mounting base. While this design facilitates disassembly and assembly, the lack of a limiting mechanism means that the protector body may experience poor contact or even detachment under external force. Furthermore, prolonged plugging can easily lead to blockage at the plug joint. When removing the protector, operators need to use tools or shake it back and forth, which can easily damage the surge protector. Therefore, a corresponding technical solution is needed to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a surge protector with overcurrent protection, which solves the problem of the common method of directly plugging the protector body into the mounting base for easy replacement. Although this design is convenient for disassembly and assembly, the lack of a limiting mechanism may lead to poor contact or even detachment of the protector body when subjected to external force. In addition, maintaining the plugged state for a long time can easily cause blockage at the plugging point. When the protector body is pulled out, the operator needs to use tools or shake the protector body back and forth to handle it, which can easily damage the surge protector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surge protector with overcurrent protection, comprising a protector mounting base with a reserved groove in the middle and several sets of protector bodies built into the reserved groove. Several sets of connectors are distributed in the reserved groove, and the protector bodies are inserted into the connectors. An embedded groove is formed between adjacent sets of connectors. Several sets of mounting openings are formed at the upper end of the protector mounting base, and a press-type assisted ejection assembly is provided in each mounting opening. The inner end of the press-type assisted ejection assembly is located in the embedded groove. The several sets of protector mounting bases are distributed one-to-one with the several sets of protector bodies. The press-type assisted ejection assembly includes a pressure rod and a push plate. The device includes a rotating shaft and a return spring. The pressure rod is movably inserted into the mounting opening. The push plate is vertically set in the embedded groove and used in conjunction with the pressure rod. The rotating shaft is inserted into the inner side of the push plate and its two ends are rotatably connected to the embedded groove. One end of the return spring is connected to the push plate and the other end is connected to the inner wall of the embedded groove. An adjustment port is provided at the bottom front end of the reserved groove. A limit component is provided in the adjustment port. The limit component includes an elastic connecting plate, a base plate, and floating baffles. The upper end of the elastic connecting plate is connected to the protector mounting base and the bottom end is connected to the base plate. Several groups of floating baffles are evenly distributed on the base plate, and the groups of floating baffles correspond one-to-one with the groups of protector bodies.

[0006] In a preferred embodiment of this utility model, several sets of sliding grooves are evenly provided at the top and bottom of the reserved groove, and several sets of rolling balls are movably disposed in the sliding grooves, with the rolling balls contacting the protector body.

[0007] In a preferred embodiment of this utility model, the push plate has a two-section structure and includes a vertically arranged upright plate and an arched plate fixed below the upright plate, wherein the middle part of the arched plate protrudes outward.

[0008] In a preferred embodiment of this utility model, the pressure rod, push plate, and rotating shaft are all made of insulating material, wherein the arched plate of the push plate is located between two adjacent sets of insertion interfaces.

[0009] In a preferred embodiment of this utility model, the surface of the elastic connecting plate is processed to form several sets of extrusion grooves, and the several sets of extrusion grooves are distributed in a stacked manner.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves the existing surge protector structure by equipping the protector mounting base with a push-type assisted ejection component.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a surge protector with overcurrent protection, comprising a protector mounting base 2 with a reserved groove 1 in the middle and several sets of protector bodies 3 built into the reserved groove 1. Several sets of insertion interfaces 4 are distributed in the reserved groove 1, and the protector bodies 3 are inserted into the insertion interfaces 4. An embedded groove 5 is formed between two adjacent sets of insertion interfaces 4. Several sets of mounting ports 6 are formed at the upper end of the protector mounting base 2, and a press-type assisted push-out component 7 is provided in the mounting port 6. The inner end of the press-type assisted push-out component 7 is located in the embedded groove 5. Several sets of protector mounting bases 2 are distributed one-to-one with several sets of protector bodies 3. The press-type assisted push-out component 7 includes a pressure rod 8, a push plate 9, a rotating shaft 10, and a return spring 11. The pressure rod 8 is movably inserted into the mounting port 6. The push plate 9 is vertically set in the embedded groove 5 and used in conjunction with the pressure rod 8. The rotating shaft 10 is inserted into the inner side of the push plate 9 and its two ends are rotatably connected to the embedded groove 5. One end of the return spring 11 is connected to the push plate 9 and the other end is connected to the inner wall of the embedded groove 5. The bottom front end of the reserved groove 1 is provided with an adjustment port 12. The adjustment port 12 is provided with a limit component 13. The limit component 13 includes an elastic connecting plate 14, a base plate 15 and a floating baffle 16. The upper end of the elastic connecting plate 14 is connected to the protector mounting base 2 and the bottom is connected to the base plate 15. The floating baffle 16 is divided into several groups and evenly distributed on the base plate 15. The several groups of floating baffles 16 are distributed one-to-one with the several groups of protector bodies 3.

[0020] Further improvements, such as Figure 2 As shown, several sets of sliding grooves 17 are evenly provided on the top and bottom of the reserved groove 1, and several sets of balls 18 are movably arranged in the sliding grooves 17, with the balls 18 in contact with the protector body 3.

[0021] Further improvements, such as Figure 3 As shown, the push plate 9 has a two-section structure and includes a vertically arranged upright plate 19 and an arched plate 20 fixed below the upright plate 19. The middle part of the arched plate 20 protrudes outward. By acting on the protector body 3 through the arched plate 20, the protector body 3 can be quickly pushed out with one click.

[0024] In use: When it is necessary to replace or disassemble the protector body 3, the operator pulls down the base plate 15 to extend the elastic connecting plate 14. At this time, the floating baffle 16 disengages from the protector body 3, thereby releasing the limiting position. Then, the operator presses the corresponding pressure rod 8 at the position of the protector body 3 to be disassembled. The pressure rod 8 moves inward and acts on the upper end of the upright plate 19. The arched plate 20 tilts up around the rotating shaft 10 and pushes the protector body 3 outward, so that the plug end of the protector body 3 disengages from the plug interface 4. At this time, the operator can quickly disassemble the protector body 3. Then, the new protector body 3 is inserted into the plug interface 4 and the floating baffle 16 is reset, thus quickly limiting and fixing the protector body 3.
