Embodiment 1

[0045] see figure 1 , figure 2 , Figure 5 , Figure 10 and Figure 11 , the embodiment of the present invention provides a photovoltaic DC surge protection device: including a surge protector 1 and an oblique protrusion 2 on the lower side thereof, the front and rear sides of the surge protector 1 pass through square grooves 5 on both sides A slide bar 6 is slidably installed, and the other side below the surge protector 1 is slidably installed with a clamping assembly 4 that cooperates with the oblique protrusion 2 to fix the surge protector 1. The inside of the surge protector 1 is provided with a The moving component 7 of the clamping component 4 is fixedly connected to one of the sliding bars 6 through the gap 15 opened on the surge protector 1. The inside of the surge protector 1 is fixedly installed with a power supply component 3. The power supply component 3 Attach to the opposite sides of the two slide bars 6 respectively. Among them, the surge protector 1 is a...

Embodiment 2

[0050] see figure 2 , Figure 9 and Figure 10 , on the basis of Embodiment 1, the front and rear sides of the surge protector 1 are provided with placement grooves 16, the inside of the placement groove 16 is provided with a rectangular block 17, the side wall of the rectangular block 17 is fixedly connected with the slide bar 6, and the rectangular block 17 A first spring 14 is fixedly installed between the bottom of the block 17 and the groove wall of the placement groove 16 .

[0051] In this embodiment, preferably: in the initial state, the rectangular block 17 is located in the middle of the placement groove 16; the placement groove 16 provided with the rectangular block 17 can ensure that the slide bar 6 slides up and down stably, and the first spring provided 14 has played the effect of supporting rectangular block 17 and slide bar 6; initial position.

[0052] As a further improvement of this embodiment: in actual use, a first spring 14 can also be installed betw...

Embodiment 3

[0054] see Figure 5 and Figure 6 , on the basis of the second embodiment, the energization component 3 includes a metal joint 301, the metal joint 301 is fixedly connected with the surge protector 1, and the inside of the metal joint 301 is slidably installed with two metal guide posts 302, and the two metal guide posts 302 A second spring 303 is fixedly mounted on the opposite side of each other.

[0055] In this embodiment, it is preferable to use the metal joint 301 and the metal guide post 302, so that after the wire is connected and fixed to the metal joint 301, the circuit conduction can be realized, and the surge protector 1 can work normally, and the metal joint 301 can also The electricity is transmitted to the metal guide posts 302 .

Abstract

The invention discloses a photovoltaic direct current surge protection device which comprises a surge protector and an inclined protrusion arranged on one side of the lower portion of the surge protector, and sliding strips are installed on the front side and the rear side of the surge protector in a sliding mode through square grooves formed in the two side faces. The other side of the lower portion of the surge protector is slidably provided with a clamping assembly matched with the inclined protrusion to achieve fixing of the surge protector, the surge protector is internally provided with a moving assembly used for fixing the clamping assembly, and the moving assembly is fixedly connected with one of the sliding strips through a notch formed in the surge protector; an electrifying assembly is fixedly mounted in the surge protector; and through cooperation of the sliding strip, the moving assembly, the clamping assembly, the inclined protrusion and the like, installation and use of a single surge protector can be achieved, assembly and use of multiple surge protectors can also be achieved, only one grounding wire needs to be prepared for the assembled whole, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of surge protection devices, in particular to a photovoltaic DC surge protection device. Background technique [0002] Surge protector, also called lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When the electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct the shunt in a very short time, so as to avoid the damage of the surge to other equipment in the circuit. [0003] Chinese Invention Patent Publication No. CN213243527U discloses a surge protection seat, which includes a base body, one side of the base body is fixedly connected with a surge protector, and a first groove is opened on one side of the base body, so Both sides of the surge protector are fixedly connected with buckles, and the inside of the base body...
