[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-8 The utility model provides a technical solution: a bus duct joint anti-dropping structure, comprising two sections of bus duct main body 100 and a connector 200 for connecting the two sections of bus duct main body 100, baffles 110 are fixedly installed on both sides of the copper bar at the connecting end of the bus duct main body 100, the connector 200 is assembled on the four baffles 110, the connector 200 includes two side plates 210 that are symmetrically distributed and both are arranged on the outside of the baffle 110, a conductive layer 230 for connecting the copper bars of the two sections of the bus duct main body 100 is clamped and fixed between the two side plates 210 by a first bolt 220, and a card slot 240 for accommodating the side card of the baffle 110 is opened at the top and bottom of the inner side of the two side plates 210.

[0033] Based on the setting of the above structure, the bus duct joint anti-falling structure is composed of a connector 200 and two sections of bus duct main bodies 100, wherein baffles 110 are fixedly installed on both sides of the copper bar at the butt joint of the two sections of the bus duct main bodies 100, and the connector 200 is assembled between the four baffles 110 to achieve the butt joint of the two sections of the bus duct main bodies 100. Specifically, during the installation process, the operator clamps the two side panels 210 on the two baffles 110 of one section of the bus duct main body 100, and then inserts the two baffles 110 of the other section of the bus duct main body 100 into the inner side of the two baffles 110, that is, the installation operation of the two side panels 210 on the four baffles 110 is achieved, and then the operator operates Personnel dock the conductive layer 230 with the copper bars of the two bus duct bodies 100, and use the first bolt 220 to clamp and fix the conductive layer 230 between the two side plates 210. The anti-falling structure of the bus duct joint has slots 240 at the top and bottom of the inner side of the side plate 210, and uses the baffles 110 on both sides of the copper bars of the docking end of the bus duct body 100 as structural support. The side plate 210 can be clamped between the two baffles 110 located in the same vertical plane, and the conductive layer 230 is clamped and fixed by the two side plates 210 with the first bolt 220, thereby preventing the connector 200 from falling off between the two sections of the bus duct body 100.

[0034] Furthermore, the side panel 210 includes two mounting seats 2110 symmetrically distributed in the upper and lower parts, the two mounting seats 2110 are fixedly connected by two second bolts 2120, and a fixing plate 2130 for the first bolt 220 to penetrate and install is fixedly connected between the middle parts of the outer sides of the two mounting seats 2110. Among them, since the bus duct main body 100 has various specifications, the corresponding baffles 110 also have different specifications and sizes. By setting the main body of the side panel 210 as two detachable mounting seats 2110 and using the second bolt 2120 to achieve a fixed connection between the two mounting seats 2110, the distance between the two mounting seats 2110 can be adjusted, and then the distance between the two card slots 240 can be adjusted to adapt to the card installation operation of baffles 110 of different specifications, thereby improving the flexibility of installation. At the same time, in the specific installation process, there is no need to move the position of the bus duct main body 100, and the installation operation of the side panel 210 can also be completed, thereby improving the convenience of installation. The fixing plate 2130 provides structural support for the installation of the first bolt 220, and can be installed by screws after the positions of the two mounting seats 2110 are fixed.

[0035] Furthermore, the nut of the first bolt 220 is set to a square nut structure, and a limit groove 2132 for sliding and clamping is provided on the outer side of the fixing plate 2130 in contact with the first bolt 220, and a thick pad layer 2131 is provided on the outer side of the fixing plate 2130 in contact with the head of the first bolt 220. The first bolt 220 uses a square nut as a locking accessory, and the limit groove 2132 adapted to the square nut can effectively prevent the nut from loosening, and the thick pad layer 2131 is integrally formed with the fixing plate 2130, which increases the supporting strength of the fixing plate 2130.

[0036] Furthermore, the top thread of the mounting seat 2110 is penetrated by a screw rod 2111 distributed in the vertical direction, and the bottom end of the screw rod 2111 is rotatably equipped with a block 2112 with a right-angle trapezoidal longitudinal section, and the outer side of the block 2112 is in close contact with the inner side of the baffle 110. The block 2112 can be pressed between the baffle 110 and the conductive layer 230 along the inner side of the baffle 110 by means of the screw rod 2111 being screwed downward, further improving the firmness of the conductive layer 230 and ensuring the docking effect of the two sections of the bus duct body 100.

[0037] Furthermore, the conductive layer 230 includes a plurality of insulating protective plates 2310 that are overlapped and spliced, and copper connecting plates 2320 are embedded on both sides of the insulating protective plates 2310. A positioning hole 2330 for the first bolt 220 to pass through and install is provided at the center of the insulating protective plate 2310. One end of the positioning hole 2330 extends vertically outward and is provided with a groove 2331 with a conical structure, and the other end of the positioning hole 2330 extends vertically outward and is provided with a protrusion 2332 that matches the groove 2331. Among them, the positioning hole 2330 is used for the through installation of the first bolt 220. At the same time, the first bolt 220 provides positioning support for several insulating protective plates 2310. Under the clamping action of the first bolt 220, the two positioning holes 2330 of the adjacent insulating protective plates 2310 are connected to each other. By providing mutually adapted grooves 2331 and protrusions 2332, a clamping structure is formed at the joint of the two positioning holes 2330, which can play a certain limiting role and further enhance the anti-falling effect.
