Description

Technical Field

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

[0002] When using outdoor LED lights or lampposts, a wire is needed to connect the power source to the LED light or lamppost. When an outdoor LED light or lamppost is struck by lightning, it will cause a sudden high voltage to be generated, which will lead to its damage. Surge protection can be used to absorb surges or voltage spikes between AC power grids to ensure that the equipment or circuits it protects are not damaged.

[0003] A search revealed that patent application number 202121095324.X discloses a power cord with surge protection function, including a circuit board. The circuit board is equipped with a thermal protection varistor and a surge protection module. The circuit board has an input terminal and an output terminal, and connecting wires are installed on the input terminal and the output terminal. Ring frames are installed on the connecting wires. Each ring frame has a circular through hole. A support rod is fitted on the corresponding ring frame. A top rod is installed on the support rod. A sleeve is fitted on the top rod. An annular washer is installed on the sleeve. The annular washer has a first threaded opening, and a first screw is inserted into the first threaded opening.

[0004] Although the surge-protected power cord protects outdoor LED lights or light poles from lightning strikes through the thermal protection varistor and surge protection module inside the circuit board, and the connection wire can be fixed in place by setting up the ring frame, support rod and ring washer, the surge-protected power cord requires the corresponding number of ring frames and support rods to be put on the connection wire in advance according to the number of fixed points, and then it is moved to the fixed position, which is relatively troublesome to use.

[0005] Therefore, we propose a power connection cable with surge protection. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a power connection cable with surge protection, which solves the problem that existing devices require pre-installing a corresponding number of ring frames and support rods on the connection cable according to the number of fixed points, and then moving it to a fixed position, which is quite cumbersome to use.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a power connection cable with surge protection, including a circuit board, on which a thermal protection varistor and a surge protector are installed, and the circuit board is provided with an input terminal and an output terminal, and the input terminal and the output terminal of the circuit board are respectively connected to a first connection line and a second connection line.

[0008] The outer surfaces of both the first and second connecting lines are fitted with fixing components;

[0009] The fixing component includes a first arc-shaped plate, a second arc-shaped plate, a locking block, a connecting strip, a locking hole, a fixing plate, a fixing hole, a rubber pad, a connecting groove, and a connecting block. The first arc-shaped plate and the second arc-shaped plate are rotatably connected. The outer surface of the first arc-shaped plate is fixedly installed with locking blocks arranged in a circular array. The second arc-shaped plate is fixedly installed with connecting strips arranged in a linear array. The spacing and specifications of the connecting strips are matched with the locking holes of the locking blocks. The locking blocks are engaged inside the locking holes.

[0010] Preferably, a connecting block is fixedly installed at the middle of one end of the first arc-shaped plate, and a connecting groove is provided at the middle of one end of the second arc-shaped plate. The connecting block is rotatably installed inside the connecting groove via a bearing. The connection groove and the connecting block are arranged to allow the first arc-shaped plate and the second arc-shaped plate to rotate around the bearing on the connecting block as an axis.

[0011] Preferably, the connecting strip is fixedly installed in the middle of the second arc-shaped plate at the end away from the connecting groove. Both the connecting strip and the locking block are made of insulating rubber. The locking block is engaged inside the locking hole, which can fix the first arc-shaped plate and the second arc-shaped plate on the outer surface of the first connecting line or the second connecting line.

[0012] Preferably, an "L"-shaped fixing plate is fixedly installed on the outer surface of the first arc plate near the connecting block and the outer surface of the second arc plate near the connecting groove. The side wall of the fixing plate is provided with fixing holes. By using screws to pass through the fixing holes, the fixing plate can be fixed in a specific installation position, thereby fixing the position of the first arc plate and the second arc plate, and thus fixing the first connecting line or the second connecting line.

[0013] Preferably, rubber pads are fixedly fitted on the outer surfaces of both the first and second arc-shaped plates. The rubber pads can prevent the insulation layer of the first or second connecting wire from being worn through by the first or second arc-shaped plate.

[0014] This invention provides a power connection cable with surge protection. It has the following advantages:

[0015] This surge-protected power connection cable, based on the required fixing position of the first or second connection cable, involves placing a first arc-shaped plate and a second arc-shaped plate over the outside of the fixing position of the first or second connection cable. Pulling the connecting strap towards the outer surface of the first arc-shaped plate engages the locking block inside the locking hole, fixing the first and second arc-shaped plates to the outer surface of the first or second connection cable. Screws are then passed through the fixing holes to fix the fixing plate in the specific installation position, thus securing the first or second connection cable. This design facilitates the fitting of fixing components onto the outer surface of the first or second connection cable, making assembly and disassembly easy. It is simple, convenient, and highly efficient in installation, solving the problem of existing devices requiring pre-fitting a corresponding number of ring frames and support rods onto the connection cable based on the number of fixing points, which is cumbersome.
