DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following describes in detail the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the scope of protection of the present utility model more clearly defined.

[0027] As Figures 1 - 3 shown, a dense insulation plug-in busbar groove includes a busbar groove housing 100. A copper bar 200 is tightly pressed and arranged on the inner wall of the busbar groove housing 100. The end face of the copper bar 200 is arranged in an inclined plane, and the two end inclined planes are centrally symmetrically arranged, which is convenient for the end faces of the copper bars 200 to be inserted and pressed against each other for fixation when connecting the end faces of the busbar groove, and the copper bars 200 are tightly pressed against each other by using the inclined plane. A plug-in male head 300 is fixedly connected to the end face of the busbar groove housing 100, and a plug-in female head 400 is fixedly connected to the end face of the busbar groove housing 100 far from the plug-in male head 300. The plug-in male head 300 and the plug-in female head 400 are arranged in cooperation.

[0028] As Figure 1 shown and Figure 3 illustrated, at positions near the end faces symmetrically on the top and bottom of the male connector 300, insertion blocks 301 are fixedly connected. The bottom of the insertion block 301 is provided with an inclined surface, and it is in mutual extrusion and pressing contact with the inclined surface provided on the top of the groove block 401, facilitating outward extrusion and fixation when connecting the male connector 300 and the female connector 400. This enables there to be a certain extrusion force when the male connector 300 and the female connector 400 are connected and fixed, improving the stability between the two. The two insertion blocks 301 are respectively in corresponding snap-fit connection with the groove blocks 401 fixedly connected symmetrically at positions near the end faces on the top and bottom of the female connector 400. A positioning block 302 is fixedly connected to the bottom of the insertion block 301. The positioning block 302 extends into the interior of the groove block 401 and is in close fit with the inner wall of the groove block 401, facilitating pre-positioning when inserting the male connector 300 and the female connector 400, and facilitating quick connection and fixation between the positioning block 302 and the groove block 401. A limiting shaft 303 is movably connected through the positioning block 302 near the end face position. A limiting hole 402 is provided at a position near the side wall of the groove block 401. The limiting shaft 303 passes through the limiting hole 402 and is in a limiting setting with the groove block 401. By using the limiting shaft 303 to pass through the groove block 401 and the positioning block 302 in sequence, the male connector 300 and the female connector 400 can be connected and fixed through the positioning block 302 and the groove block 401.

[0029] As Figure 3 shown and illustrated, auxiliary components are fixedly connected symmetrically at positions near the end faces on the front wall and the rear wall of the male connector 300, and are in cooperative connection with the clamping blocks 403 fixedly connected symmetrically at positions near the end faces on the front wall and the rear wall of the female connector 400 through the auxiliary components. The auxiliary component includes a fixed block 304 fixedly connected to the middle position of the front wall of the male connector 300. A sliding rod 305 is slidably connected through the middle of the fixed block 304. A collar 306 is rotatably connected to the end face of the sliding rod 305. A spring 307 is wrapped around the outer wall of the sliding rod 305 at a position away from the collar 306. An adjusting nut 308 is fixedly connected to the end face of the sliding rod 305. The collar 306 is sleeved on the clamping block 403, thereby pulling the sliding rod 305, causing it to drive the adjusting nut 308 to compress the spring 307. And by using the reset operation of the spring 307, the adjusting nut 308 drives the collar 306 on the sliding rod 305 to tightly pull and fix the clamping block 403. The end faces of the spring 307 are in pressing contact with the fixed block 304 and the adjusting nut 308 respectively, facilitating using the compression and resilience of the spring 307 to drive the adjusting nut 308 to pull the sliding rod 305 for reset, and further enabling stable insertion and fixation between the male connector 300 and the female connector 400.

[0030] When the utility model is in use, first, the busbar trunking is tightly fixed to each other correspondingly through the inclined surface of the copper bar 200, and the positioning block 302 on the male plug 300 is pre-inserted into the inner part of the groove block 401. Under the action of the inclined surfaces of the insertion block 301 and the groove block 401, the two are tightly pressed against each other, so as to improve the stability during connection. Then, the limiting shaft 303 is inserted through the limiting hole 402, so that the positioning block 302 is fixed to the groove block 401. Then, the collar 306 is pulled, and the collar 306 is sleeved on the clamping block 403, so as to pull the sliding rod 305, so that the adjusting nut 308 drives the compression of the spring 307. And by using the reset operation of the spring 307, the adjusting nut 308 drives the collar 306 on the sliding rod 305 to tightly tighten and fix the clamping block 403.

[0031] The above are only the embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
