Description

Technical Field

[0001] This invention specifically relates to a surge protector. Background Technology

[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic devices, 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. A surge protector includes a base, incoming terminal blocks, outgoing terminal blocks, and a lightning protection module. Existing surge protectors have unreasonable structural designs and lack power-on / power-off indication functions. Users cannot intuitively know the operating status of the surge protector, and these surge protectors lack power-on / power-off backup remote signaling functions. The backend cannot know the operating status of this backup protector, making real-time monitoring of the backup protector impossible. This results in low safety performance, and the backup surge protector also suffers from defects such as complex structure, unreliable performance, and inconvenient assembly. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a surge protector that is simple in structure, stable and reliable in performance, easy to assemble, and has power-on and power-off indication functions.

[0004] To achieve the above objectives, the present invention employs a surge protector, comprising a base, a top cover, a surge protection module mounted on the base, an outgoing terminal connected to one end of the surge protection module, and an incoming terminal. A power-on / power-off indicator mechanism is provided between the other end of the surge protection module and the incoming terminal. The power-on / power-off indicator mechanism includes a guide rod mounted within the base, a conductive positioning plate soldered to the conductive plate of the surge protection module, a push block linked to the conductive positioning plate, a spring between the conductive positioning plate and the base, a support base mounted on the surge protection module, an indicator slidably mounted on the support base and cooperating with the push block, a reset spring between the support base and the indicator, and a copper busbar between the conductive positioning plate and the incoming terminal. The conductive positioning plate and the push block are respectively provided with guide holes through which the guide rod can pass. The indicator is respectively provided with a power-off mark and a power-on mark. The top cover is provided with an indicator hole corresponding to the indicator. The push block moves with the conductive positioning plate and can push the indicator to move.

[0005] The advantages of the above structure are: a power-on / power-off indicator mechanism is installed between the surge protection module and the incoming terminal block. This mechanism has a simple design and provides accurate indication. When the surge protector is subjected to a large impact, the temperature of the conductive positioning plate rises, the solder between the conductive positioning plate and the conductive plate melts, and the conductive positioning plate separates from the conductive plate. The spring pushes the conductive positioning plate and the push block upwards, and the push block pushes the indicator to slide, thus realizing the power-off indication of the surge protector. During power failure, the spring can push the push block to move quickly, making the indication action of the power-on / power-off indicator mechanism more sensitive. Therefore, this surge protector has the advantages of simple structure, stable and reliable performance, convenient assembly, and power-on / power-off indication function.

[0006] Specifically, the cover body is equipped with a remote signaling module that cooperates with the indicator. The remote signaling module includes a circuit board disposed within the cover body, a microswitch disposed on the circuit board, and a signal terminal disposed on the base and electrically connected to the circuit board. One end of the indicator has a protrusion that cooperates with the microswitch. The protrusion moves with the indicator and can trigger the microswitch, thus enabling the microswitch to be turned on or off. The remote signaling module can monitor the position of the indicator, and the microswitch can send the monitored operating status signal to the backend, thereby realizing the remote signaling function of the surge protector.

[0007] Specifically, the push block is provided with a driving inclined surface that cooperates with the indicator, and the other end of the indicator is provided with a load-bearing inclined surface that cooperates with the driving inclined surface. The driving inclined surface moves with the push block and can abut against the load-bearing inclined surface, thus forming a linkage between the push block and the indicator. The driving inclined surface on the push block can reliably and smoothly drive the indicator to move, thereby improving the indicating accuracy of the power-on / power-off indicator mechanism.

[0008] Specifically, the support base is provided with a guide protrusion, and the indicator has a sliding hole that mates with the guide protrusion. The guide protrusion is inserted into the sliding hole, and the two ends of the return spring abut against the guide protrusion and the indicator, respectively. The indicator is slidably mounted on the guide protrusion, which facilitates the assembly of the indicator and the support base and ensures reliable sliding of the indicator, resulting in higher reliability.

[0009] Specifically, the push block is provided with two elastic buckles, and the conductive positioning plate is provided with two locking holes that mate with the two elastic buckles. The two elastic buckles are respectively engaged in the two locking holes, forming a snap-fit ​​engagement between the two elastic buckles and the conductive positioning plate. The push block and the conductive positioning plate are connected by a snap-fit ​​engagement, which facilitates the assembly of the push block and the conductive positioning plate, making the assembly more efficient.

[0010] Specifically, the base is provided with a positioning groove that mates with the guide rod. One end of the guide rod is inserted into the positioning groove, forming a snap-fit ​​connection between the base and the guide rod. The spring is fitted onto the guide rod. The guide rod and the base are connected by a snap-fit ​​connection, which facilitates the assembly of the base and the guide rod, making assembly more convenient. Attached Figure Description

The indicator 26 is respectively provided with a power-off indicator 261 and a power-on indicator 262. The upper cover 11 is provided with an indicator hole 111 corresponding to the indicator 26. The push block 23 moves with the conductive positioning plate 22 and can push the indicator 26 to move. The surge protection module 12 includes a support frame 121 disposed within the base 10, multiple graphite sheets 122 disposed within the support frame 121, multiple insulating sheets 123 disposed between the multiple graphite sheets 122, and a surge protection circuit board 124 disposed on the support frame 121. The cover 11 contains a remote signaling module 30 that cooperates with the indicator 26. The remote signaling module 30 includes a circuit board 31 inside the cover 11, a micro switch 32 on the circuit board 31, and a signal terminal 33 on the base 10 and electrically connected to the circuit board 31. One end of the indicator 26 has a protrusion 263 that cooperates with the micro switch 32. The protrusion 263 moves with the indicator 26 and can trigger the micro switch 32, thus turning the micro switch 32 on or off. The remote signaling module can monitor the position of the indicator, and the micro switch can send the monitored operating status signal to the backend, thereby realizing the remote signaling function of the surge protector.

[0017] like Figure 2 , 3As shown in Figure 5, the push block 23 is provided with a driving inclined surface 231 that cooperates with the indicator 26. The other end of the indicator 26 is provided with a load-bearing inclined surface 264 that cooperates with the driving inclined surface 231. The driving inclined surface 231 moves with the push block 23 and can abut against the load-bearing inclined surface 264, thus forming a linkage between the push block 23 and the indicator 26. The driving inclined surface on the push block, which cooperates with the indicator, can reliably and smoothly drive the indicator, thereby improving the accuracy of the power-on / power-off indicator mechanism. The support base 25 is provided with a guide protrusion 251. The indicator 26 has a sliding hole 265 that cooperates with the guide protrusion 251. The guide protrusion 251 passes through the sliding hole 265. The two ends of the return spring 27 abut against the guide protrusion 251 and the indicator 26, respectively. The indicator is slidably mounted on the guide protrusion, facilitating the assembly of the indicator with the support base and ensuring reliable sliding of the indicator, thus improving reliability. The push block 23 has two elastic buckles 231, and the conductive positioning plate 22 has two locking holes 221 that mate with the two elastic buckles 231.

The push block and the conductive positioning plate are connected by a snap-fit ​​engagement, facilitating the assembly of the push block and the conductive positioning plate and improving assembly efficiency. The base 10 has a positioning groove 101 that mates with the guide rod 21. One end of the guide rod 21 passes through the positioning groove 101, forming a snap-fit ​​engagement between the base 10 and the guide rod 21. The spring is fitted onto the guide rod. The guide rod and the base are connected by a snap-fit ​​engagement, facilitating the assembly of the base and the guide rod and making assembly more convenient.

[0018] A power-on / power-off indicator mechanism is installed between the surge protection module and the incoming line terminal. This mechanism has a simple design and provides accurate indication. When the surge protector is subjected to a large impact, the temperature of the conductive positioning plate rises, the solder between the conductive positioning plate and the conductive plate melts, and the conductive positioning plate separates from the conductive plate. A spring pushes the conductive positioning plate and the push block upwards, and the push block pushes the indicator to slide, thus realizing the power-off indication of the surge protector. When the power is off, the spring can push the push block to move quickly, making the indication action of the power-on / power-off indicator mechanism more sensitive. Therefore, this surge protector has the advantages of simple structure, stable and reliable performance, convenient assembly, and power-on / power-off indication function.
