DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figures 1 to 3 As shown, the high-voltage plug-in conductive column includes an arc cover 100, a connecting column 200 and a spherical part 300, which are integrated. The arc cover 100 is connected to the connecting column 200, and the outer surface of the arc cover 100 and the inner wall of the connecting column 200 are continuous surfaces. The connecting column 200 extends downward and communicates with the spherical part 300, and the spherical part 300 is a cavity structure. The integrated cavity structure can simplify the conductive column structure, reduce the overall weight, and facilitate the installation and use of the conductive column.

[0017] A conductive rod through hole 110 is formed at the top of the connection between the arc cover 100 and the connecting column 200, and an internal thread 120 is circumferentially provided on the inner wall of the connecting column 200 near the conductive rod through hole 110. The conductive rod is inserted into the spherical part 300 through the conductive rod through hole 110 and is connected by the internal thread 120.

[0018] The spherical part 300 is respectively formed with a first flange 310, a second flange 320 and a buffer part 330 on the spherical side, and a contact flange 340 is formed at the bottom coaxial with the connecting column 200. The conductive column is provided with a plurality of functional holes on the spherical part 300, which effectively improves the functionality of the conductive column.

[0019] A first through hole 311 is provided at the center of the first flange 310. In actual use, an insulator that blocks the conductive rod can be inserted into the first through hole 311. A plurality of first mounting holes 312 are evenly provided around the first through hole 311 on the first flange 310. The first mounting holes 312 are used to connect the insulator and its matching structure.

[0020] The first flange 310 and the buffer part 330 are coaxially arranged, and the buffer part 330 protrudes from the outer surface of the spherical part 300. The first through hole 311 at the center of the first flange 310 points to the buffer groove 331 of the buffer part 330 located inside the spherical part 300. The inner wall of the spherical part 300 and the buffer groove 331 are smoothly connected. The buffer groove 331 and the buffer part 330 are used to buffer the insulator when it is plugged in and out of the first through hole 311. The buffer part 330 has a plurality of heat dissipation holes 332 uniformly opened around the center of the bottom of the buffer groove 331, and the heat dissipation holes 332 play a role in dissipating heat inside the spherical part 300 during operation.

[0021] The diameter of the second flange 320 is smaller than that of the first flange 310. A second through hole 321 is provided at the center of the second flange 320. The second through hole 321 is not used for installing circuits, but acts as a heat dissipation window to dissipate heat inside the spherical part 300. A plurality of second mounting holes 322 are evenly provided on the second flange 320 around the second through hole 321. The second mounting holes 322 can cooperate with other electrical components to mount and fix the conductive column thereto.

[0022] like Figure 2 As shown, the contact flange 340 is annular in shape as a whole, with a contact through hole 341 at the center, and a plurality of limit blocks 342 are formed on the inner side wall of the ring evenly protruding toward the center, and a third mounting hole 343 is provided on the limit block 342. Due to the uneven inner ring side wall of the contact flange 340, the contact through hole 341 is equipped with a contact to play a positioning and limiting role, and the third mounting hole 343 can further fix the contact to the ball part 300.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0024] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
