Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, specifically to an onboard 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.

[0003] However, existing surge protectors contain a module with two pins, a lever, and a chip. The two ends of the chip are connected to the corresponding pins via solder. When an overload or over-protection event occurs, the solder melts, the lever moves, and the chip separates from the pin. However, while this structure achieves separation due to the lever's movement, its complex design and limited internal space result in slow separation and potential arcing, severely impacting the overall surge protection effectiveness. Summary of the Invention

[0004] The purpose of this invention is to provide an onboard surge protector to address the shortcomings of existing surge protectors mentioned in the background section. These existing surge protectors typically have a module with two pins, a lever, and a chip. The chip's two ends are connected to the corresponding pins via solder. In the event of overload or over-protection, the solder melts, the lever moves, and the chip separates from the pin. However, while this structure achieves separation due to the lever's movement, its complex design and limited internal space result in slow separation and potential arcing, severely impacting the overall cutoff performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an onboard surge protector, comprising a base, wherein a connector is provided on the surface of the base, and a protector body is connected to the connector.

Chips are fixedly installed on the surfaces of the partition plate on both the first and second chambers. Fixing plates are fixedly connected to both ends of the partition plate above the chips. Contact blocks are slidably connected to one side of the fixing plate, and conductive elements are fixedly installed on the other side of the fixing plate. The conductive elements are connected to the chips through electrode plates. A rotation port is provided at the bottom of the housing at the relative position of the first and second chambers, and a toggle assembly is rotatably connected to the rotation port. The top of the toggle assembly is connected to the contact blocks.

[0006] Preferably, pins are fixedly installed on both sides of the first and second chambers inside the housing, and the pins are connected to the conductive components by welding.

[0007] Preferably, the actuation assembly includes a rotating rod, an actuating rod, and a contact rod. The rotating rod is fixedly connected to the rotating opening. The actuating rod and the contact rod are rotatably connected to the surface of the rotating rod, and the contact rod is located inside the actuating rod. The top of the actuating rod is connected to the surface of the contact block. The actuating rod and the contact rod adopt an integral molding structure design.

[0008] Preferably, the outer surface of the contact block has a movable opening, and a toggle lever is movably connected inside the movable opening.

[0009] Preferably, the surface of the connector has a connector opening at the position opposite to the pin, and the pin is connected to the connector opening; the surface of the connector has a contact opening at the position opposite to the contact rod, and the contact rod is connected to the contact opening.
