[0044] Please refer to Figure 1 and Figure 2 , which is a preferred embodiment of the present utility model. The busbar connector includes: an upper cover plate 100, including an upper cover plate linear flange 110; a lower cover plate 200, which is snap-connected to the upper cover plate 100; an installation cavity 800 is formed between the upper cover plate 100 and the lower cover plate 200; the lower cover plate 200 includes a lower cover plate linear flange 210, and the lower cover plate linear flange 210 is disposed opposite to the upper cover plate linear flange 110; a connection module 300, fixedly installed in the installation cavity 800; including a copper bar 350, both ends of the copper bar 350 are provided with insertion segments 351 (the externally exposed connection parts of the copper bar), and the insertion segments 351 are overlapped with the upper cover plate linear flange 110 and the lower cover plate linear flange 210; an infrared temperature measurement collector 600, fixedly installed on the upper cover plate 100 or the lower cover plate 200.

[0045] By adopting infrared temperature measurement technology, this busbar connector significantly improves safety compared with traditional contact temperature measurement methods. Infrared temperature measurement does not require physical contact, effectively avoiding potential safety risks during operation or power-off disassembly. The insertion section 351 of the copper bar 350 overlaps with the upper cover plate straight flange 110 and the lower cover plate straight flange 210, effectively increasing the current-carrying capacity of conduction. The combined effect of these innovative points makes this busbar connector superior to traditional products in terms of safety and current transmission.

[0046] In an embodiment of the present application, the busbar connector mainly includes an upper cover plate 100, a lower cover plate 200, and a connection module 300. The following further details each of the above components.

[0047] As Figure 1 and Figure 2 shown, the upper cover plate 100 and the lower cover plate 200 are snap-connected together to form an installation cavity 800 between the upper cover plate 100 and the lower cover plate 200.

[0048] Most ordinary connector cover plates are made of sheet metal structures, with many gaps, making it difficult to handle dust and water protection, and having poor heat dissipation. The upper cover plate 100 and the lower cover plate 200 are integrally die-cast from aluminum, with high dimensional accuracy and high strength. Due to the integral molding, they fit well with the shapes of other components, making it easy to handle dust and water protection. Their dust-proof, waterproof, and heat dissipation performance is superior to that of ordinary connectors.

[0049] Specifically, the upper cover plate 100 includes two opposite upper cover plate straight flanges 110 and two opposite upper arc segments 120. The two ends of the upper cover plate straight flange 110 are respectively adjacent to the two upper arc segments 120, and the upper cover plate straight flange 110 and the upper arc segments 120 are arranged end to end around the upper cover plate 100. A plurality of mutually parallel upper waterproof ribs (not shown in the figure) are provided on the upper cover plate 100, and the upper waterproof ribs are provided on the upper cover plate straight flange 110. A locking structure 140 is also provided on the upper cover plate straight flange 110 for tightly connecting with other structures, further optimizing the dust-proof and waterproof performance of this busbar connector.

[0050] Similarly, the lower cover plate 200 includes two opposite lower cover plate straight flanges 210 and two opposite lower arc segments 220. The two ends of the lower cover plate straight flange 210 are respectively adjacent to the two lower arc segments 220, and the lower cover plate straight flange 210 and the lower arc segments 220 are arranged end to end around the lower cover plate 200. A plurality of mutually parallel lower waterproof ribs 230 are provided on the lower cover plate 200, and the lower waterproof ribs 230 are provided on the lower cover plate straight flange 210.

[0051] As Figure 2As shown, after the upper cover plate 100 and the lower cover plate 200 are snap-connected together, the straight flange 110 of the upper cover plate is disposed opposite to the straight flange 210 of the lower cover plate; the upper arc segment 120 and the lower arc segment 220 are fixedly connected together.

[0052] To further improve the waterproof performance, as Figure 1 shown, in an embodiment of the present application, the busbar connector further includes an elastic pad 400 for waterproofing. The elastic pad 400 is disposed between the upper arc segment 120 and the lower arc segment 220 and is in close fit with both, which can provide a positive extrusion force to the elastic pad 400, further improving the IP protection level.

[0053] The busbar connector has optimized the waterproof and dustproof performance, thus significantly improving the IP protection level, enabling the busbar connector to operate stably even in harsh environments.

[0054] The infrared temperature measurement collector 600 is fixedly installed on the outer surface of the upper cover plate 100 or the lower cover plate 200. For example, as Figure 1 shown, the infrared temperature measurement collector 600 is fixedly installed on the outer surface of the lower cover plate 200. The infrared temperature measurement collector 600 is a device that uses infrared technology for non-contact temperature measurement. It determines the temperature of the copper bar 350 by detecting the infrared radiation energy emitted by the copper bar 350 without directly contacting the copper bar 350.

[0055] As Figure 1 and Figure 2 shown, an observation hole 500 is provided on the upper cover plate 100 and / or the lower cover plate 200, which is convenient for torque inspection during later operation and maintenance and for maintenance without power interruption. A sealing rubber plug 510 is disposed at the observation hole 500.

[0056] The busbar connector further includes a fastener 700 for detachably connecting the upper cover plate 100 and the lower cover plate 200. Preferably, the fastener 700 is a reduced-diameter non-dropping screw. The reduced-diameter non-dropping screw can be hung on the lower cover plate 200 during installation and disassembly, avoiding the safety hazards caused by the dropping and loss of ordinary screws on site.

[0057] As Figure 1 shown, the lower cover plate 200 is provided with an anti-fooling structure 260 for cooperating with the connection module 300. The anti-fooling structure 260 is a protrusion for cooperating with the connection module 300, preventing the assembly direction of the connection module 300 and the straight flange 210 of the lower cover plate 200 of the lower cover plate 200 from being incorrect.

[0058] As Figure 1As shown, the busbar connector further includes a lower insulating partition 240. The lower insulating partition 240 is laid on the bottom of the lower cover plate 200. A plurality of partition protrusions 250 arranged side by side are provided on the lower insulating partition 240, and the partition protrusions 250 extend along the insertion direction.

[0059] The connection module 300 includes one or more copper bars 350 arranged side by side. Preferably, the copper bars 350 are double-sided conductive copper bars. Insertion segments 351 are provided at both ends of the copper bar 350, and the insertion segments 351 are lapped with the upper cover plate linear flange 110 and the lower cover plate linear flange 210. The busbar connector uses the double-sided copper bars 350 to lap on the upper cover plate linear flange 110 and the lower cover plate linear flange 210, effectively increasing the current-carrying capacity of conduction.

[0060] In an embodiment of the present application, as Figure 1 shown, the connection module 300 further includes a fixing plate 310 fixedly connected to the copper bar 350. The fixing plate 310 is used to fixedly connect the copper bar 350 to the upper cover plate 100 or the lower cover plate 200. Specifically, as Figure 3 shown, the fixing plate 310 is installed on the upper cover plate 100 through fasteners such as screws. With such a setting, the connection module 300 is fixed on the upper cover plate 100, which can play a role in preventing shaking and positioning during transportation.

[0061] As Figure 4 shown, the connection module 300 further includes an insulating cover plate 320, and the insulating cover plate 320 covers the top of the copper bar 350. Specifically, the insulating cover plate 320 includes an upper overlapping sub-plate 321 and a lower overlapping sub-plate 322. The upper overlapping sub-plate 321 and the lower overlapping sub-plate 322 are respectively arranged on both sides of the top of the copper bar 350 and are offset in the vertical direction, so that the upper overlapping sub-plate 321 of a certain copper bar 350 overlaps the lower overlapping sub-plate 322 of the adjacent copper bar 350. The busbar connector adopts multiple insulation protections, and its dielectric performance is stronger than that of ordinary connectors.

[0062] Further, the busbar connector further includes an insulating projection 330. Preferably, the insulating projection 330 is a rubber washer. The insulating projection 330 is disposed below the upper overlapping plate 321, and a gap for clamping the lower overlapping plate 322 of the adjacent busbar 350 is formed therebetween. The insulating projection 330 of a certain busbar 350 cooperates with its upper overlapping plate 321 to clamp the lower overlapping plate 322 of the adjacent busbar 350. The insulating projection 330 can fix the busbar 350 on the insulating cover plate 320, effectively preventing the busbar 350 from shaking, and at the same time defining the distance between the two busbars 350 to keep the distance that can be inserted into the straight flange 110 of the upper cover plate and the straight flange 210 of the lower cover plate, facilitating the installation of the busbar 350 in the upper cover plate 100 and the lower cover plate 200.

[0063] As Figure 4 shown, an insulating side plate 340 is provided at the bottom of the busbar 350, and the insulating side plate 340 abuts against the separating projection 250 to define the installation position of the busbar 350 in the lower cover plate 200.

[0064] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, many changes can be made in the specific implementation manners and application scopes according to the idea of the present invention. As long as these changes do not depart from the concept of the present invention, they all belong to the protection scope of the present invention.
