Description

Technical Field

[0001] The utility model relates to the technical field of surge protectors, and more specifically, to a direct current power supply parallel type surge protector which is easy to install. Background Art

[0002] A DC power parallel type surge protector is a protective device used in DC circuit systems to prevent equipment in the circuit from being damaged by sudden situations such as lightning strikes and power surges. This type of protector is usually installed in a DC power system and connected in parallel with the circuit to provide additional protection. General surge protectors lack certain protection during installation and are easily damaged by impact.

[0003] After searching, a Chinese patent with announcement number CN220107576U discloses a new type of surge protector. This utility model can use a protective shell to protect the surge protector without affecting the wiring, reducing the damage caused by the surge protector being hit. The device can observe the use of the surge protector through a transparent observation panel.

[0004] When the above surge protector is in use, a wiring hole is provided on the surge protector body, and a wire connector is inserted into the wiring hole to connect the surge protector body for use. However, it is inconvenient to directly plug the surge protector body into a power socket, and the scope of application is small. Utility Model Content

[0011] Furthermore, the top end of the partition is fixedly connected to the protective plate, the front side of the clamping plate is fixedly connected to the partition, the front end of the second screw rod is fixedly connected to the clamping plate, and the rear end of the second screw rod passes through the support frame, and the threaded sleeve is movably mounted on the second screw rod.

[0012] Furthermore, two limit plates are movably sleeved on the clamping plate, and the rear sides of the two limit plates are fixedly connected to the support frame.

[0013] It can be seen that in the above technical solution, the card plate is not easily deflected, which can improve the stability between the card plate and the support frame.

[0014] Furthermore, two side plates are fixedly connected to both sides of the protection plate, and one side of the four side plates is in contact with the surge protector body.

[0015] It can be seen that in the above technical solution, the protective plate is not easily deflected, which can improve the stability between the protective plate and the surge protector body.

[0016] Technical effects and advantages of the utility model:

[0017] 1. The utility model can protect the equipment from damage caused by surge by inserting the wire connector into the wiring head. The switch is turned off so that the current cannot enter the surge protector body through the wiring head. The handle is turned to drive the first screw rod to rotate. Since the first screw rod is threadedly connected to the support frame, the slide bar limits the rotation of the support frame. Therefore, the first screw rod can drive the support frame to move upward and allow the plug to pass through the support frame. Then, the plug is directly plugged into the power socket. Similarly, the plug is pulled out and protected by the support frame. The structure is simple, easy to install, and has a wide range of applications.

[0018] 2. The utility model places the card plate on the front side of the support frame, inserts the second screw rod into the support frame, and then limits the second screw rod through the threaded sleeve, so that the card plate and the support frame are fixed, the display screen and buttons on the top of the surge protector body are protected by the protective plate, the partition plate separates the wire connectors on the terminal head, and the card plate is disassembled in the same way. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
