[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment

[0024] As Figure 1 and Figure 2 shown, a Y-shaped DC surge protector proposed in an embodiment of the present invention includes a protector base 1 and a protector main body 2 clamped on one side of the protector base 1. A wiring component 3 is arranged on one side of the protector base 1. The wiring component 3 includes a wiring board 301 fixedly connected to the protector base 1 and an external wiring harness 308 connected to an external device. A spiral conducting wire 307 is connected to the external wiring harness 308, and a wiring post 304 is fixedly connected to the wiring board 301. A spiral groove 305 is formed along the length direction of the wiring post 304 on the wiring post 304, and the spiral conducting wire 307 is closed into the spiral groove 305 of the wiring post 304.

[0025] It should be noted that the protector main body 2 is clamped on the protector base 1 to realize the connection of the protector main body 2 on the protector base 1. The setting of the wiring component 3 can realize the electrical connection between the external device and the surge protector. The wiring board 301 realizes the installation and protection of the wiring post 304. The wiring post 304 is electrically connected to the protector. By forming a spiral groove 305 on the wiring post 304 and connecting a spiral conducting wire 307 to the external wiring harness 308, and closing the spiral conducting wire 307 into the spiral groove 305 of the wiring post 304, the spiral conducting wire 307 and the wiring post 304 are tightly connected, increasing the tightness of the wiring harness connection, and then it is not easy to slip and fall off, ensuring the stable operation of the device, and there will be no poor contact even after long-term use.

[0026] As Figure 2As shown, in some embodiments, a circular groove 3011 is provided at one end of the terminal 304 located in the spiral groove 305, and a protrusion 306 is fixedly connected to the end of the spiral conductive wire 307 away from the external wire harness 308, and the protrusion 306 is closed into the circular groove 3011.

[0027] It should be noted that the protrusion 306 is closed in the circular groove 3011 of the terminal 304 for positioning. When an external force accidentally pulls the external wire harness 308 or the spiral conductive wire 307, the spiral conductive wire 307 will not fall off, realizing the stable connection of the spiral conductive wire 307 on the terminal 304.

[0028] As Figure 2 shown, in some embodiments, a card slot 3010 is provided at the other end of the terminal 304 located in the spiral groove 305, and the spiral conductive wire 307 extends to the outside of the terminal 304 through the card slot 3010.

[0029] It should be noted that the card slot 3010 functions to limit the wire and arrange the wires. The setting of the card slot 3010 facilitates the wiring of the spiral conductive wire 307. The spiral conductive wire 307 extends to the outside of the terminal 304 through the card slot 3010. When wiring, the spiral conductive wire 307 will also be closely fitted at the terminal 304 to avoid loosening, realizing the tight connection of the wire harness.

[0030] As Figure 2 and Figure 3 shown, in some embodiments, a protective sleeve 309 is sleeved on the terminal 304 and the external wire harness 308. The protective sleeve 309 is connected to a circular positioning seat 302 provided on one side of the wiring board 301. The protective sleeve 309 is composed of a cylinder body 3091, an expansion section 3095 connected to one side of the cylinder body 3091, and a sealed outer cylinder 3096 integrally formed on the expansion section 3095. An internal thread 3097 is provided on the inner wall of the sealed outer cylinder 3096, and an external thread 303 is provided on the outer wall of the circular positioning seat 302. The sealed outer cylinder 3096 is connected to the circular positioning seat 302 through the mating relationship between the internal thread 3097 and the external thread 303.

[0031] It should be noted that the protective sleeve 309 can provide safety protection for the terminal 304, the spiral conductive wire 307 and the external wire harness 308 to avoid external electric leakage. At the same time, the cylinder body 3091 can make the terminal 304 and the spiral conductive wire 307 closely connected, playing a role in limiting. The sealed outer cylinder 3096 is connected to the circular positioning seat 302 through the mating relationship between the internal thread 3097 and the external thread 303, facilitating the assembly of the protective sleeve 309.

[0032] As Figure 2 and Figure 3As shown, in some embodiments, the inner wall of the cylinder body 3091 abuts against the outer wall of the terminal 304 and the outer wall of the spiral conductive wire 307 respectively, and a binding sleeve 3093 is fixedly connected to the side of the cylinder body 3091 away from the sealed outer cylinder 3096. The external wire harness 308 extends to the outside of the cylinder body 3091 through the binding sleeve 3093.

[0033] It should be noted that the inner wall of the cylinder body 3091 abuts against the outer wall of the terminal 304 and the outer wall of the spiral conductive wire 307 respectively, which can enable the spiral conductive wire 307 to be closely fitted on the terminal 304 to ensure the stable connection of the wire harness. The external wire harness 308 extends to the outside of the cylinder body 3091 through the binding sleeve 3093. The binding sleeve 3093 contacts the external wire harness 308 to play an anti-slip role and achieve the close protection of the external wire harness 308.

[0034] As Figure 3 shown, in some embodiments, an insulating anti-slip sleeve 3092 is fixedly connected to the outer wall of the cylinder body 3091, and anti-slip grooves 3094 are provided on the insulating anti-slip sleeve 3092 to facilitate the hand-held operation of the cylinder body 3091.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
