Description

Technical Field

[0001] The utility model relates to the technical field of protectors, in particular to a surge protector structure. Background Art

[0002] A surge protector, also called a lightning arrester, is an electronic device that provides safety protection for various electronic devices, 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 in an extremely short time, thereby avoiding damage to other devices in the circuit caused by the surge.

[0003] When the current surge protector is in use, it is necessary to assemble the surge protection mold onto the base, and then install the base on the circuit. When the protector bears a high voltage, the resistor in the module will fail, causing the indicating structure in the module to be pulled, and the green mark in the module to turn yellow, indicating that the module has lost its effect and needs to be replaced with the same module. Therefore, the surge protector needs to be regularly inspected to avoid losses caused by the damage of the module on it without timely replacement. Therefore, the current surge protector lacks a necessary alarm structure to prompt people to replace the internal module.

[0004] Based on this, a surge protector structure is proposed. Content of the Utility Model

[0021] Hereinafter, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0023] A surge protector structure includes a housing 1, a module 2 is connected above the housing 1, an indicating groove 11 is opened above the module 2, and the indicating groove 11 is mainly used to show whether the module 2 has a protection effect. When the color in the indicating groove 11 changes, it means that the mold 2 has lost its effectiveness. A pressing plate 12 is connected to the outside of the module 2. When the module 2 is buckled on the housing 1, the pressing plate 12 can press the pressing strip 13 structure. An articulated frame 3 is connected to the housing 1, a clamping plate 4 is rotatably connected to the articulated frame 3, a ferrule 5 is arranged above the clamping plate 4, and by setting the ferrule 5, the firmness of the structural connection is increased. An alarm mechanism for detecting and alarming the failure of the module 2 is connected to the clamping plate 4.

[0024] Specifically, as Figure 2 shown, a pressing strip 13 is connected to the clamping plate 4, the lower end of the pressing plate 12 is mutually attached to the upper end of the pressing strip 13. When the module 2 is assembled on the housing 1, the clamping plate 4 needs to be deflected towards the module 2 side to ensure that the pressing strip 13 can contact the pressing plate 12.

[0025] Specifically, as Figure 2 shown, a limiting strip 14 is connected to the clamping plate 4, the lower end of the limiting strip 14 is mutually attached to the upper end of the module 2, and the limiting strip 14 is used to ensure the unified connection state of each module 2.

[0026] Specifically, as Figure 2 and Figure 3 shown, the alarm mechanism includes a docking block one 6, the docking block one 6 is connected to the limiting strip 14, a docking block two 7 is connected to the limiting strip 14, a plug 16 is connected to one side of the docking block two 7. By setting the plug 16 structure, the stable docking between the docking block one 6 and the docking block two 7 is realized. During docking, the circuit 15 at the connection between the docking block one 6 and the docking block two 7 is connected. A circuit 15 is connected to the docking block two 7, an alarm 17 is connected to the docking block one 6, and a circuit 15 is also arranged on the docking block one 6, and this circuit 15 is mutually connected to the alarm 17.

[0027] Specifically, as Figure 3 shown, a pressing block 10 is slidably connected to the docking block two 7, a contact 18 is connected to the pressing block 10, the lower end of the pressing block 10 is mutually fitted with the indicating groove 11. When the pressing block 10 drops, the contact 18 connected to the pressing block 10 can be placed on the circuit 15, so that the circuit 15 at this place is in a connected state.

[0028] Specifically, as Figure 3As shown, a spring frame 8 is connected to the upper end of the docking block two 7. A pressing spring 9 is connected to the lower end of the spring frame 8, and the lower end of the pressing spring 9 is connected to the pressing block 10. By providing the pressing spring 9, the protector can trigger an alarm even when it is not in a vertical state.

[0029] In summary, for the surge protector structure provided in this embodiment, when the surge protection module 2 on the current surge protector fails, the green block inside will be twitched. At this time, what is exposed to the external environment is yellow, indicating that the protection module 2 has failed.

[0030] And an alarm mechanism is added to this protector structure on the basis of the original structure. When the green block is twitched and its height changes, the pressing block 10 drops, causing the contact 18 on the pressing block 10 to connect the circuit 15 at this place. When all the pressing blocks 10 drop, the circuit 15 is completely connected, and the alarm 17 plays a role to indicate that the module 2 structure needs to be replaced.

[0031] When installing this surge protector structure, multiple modules 2 need to be installed on the housing 1. Flip the clamping plate 4 so that the pressing plate 12 presses on the pressure bar 13. At this time, the limiting bar 14 can press on the upper end of the module 2. Then, the docking block one 6 and the docking block two 7 are docked, and the plug 16 structure is inserted into the docking block one 6. At this time, the lower end of the pressing block 10 abuts against the green slider in the indicating groove 11. When the module 2 works, the green slider is pulled out. At this time, under the action of the pressing spring 9, the lower end of the pressing block 10 presses on the yellow housing 1, and the height of the pressing block 10 drops. The contact 18 structure connected to the pressing block 10 is connected to the circuit 15 at this place.

[0032] The automatic alarm function is realized through this surge protector structure, and the installation states of all the modules 2 are unified, avoiding the single module 2 popping out and causing the device to fail to play the protection effect.

[0033] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
