[0002] As a common support and protection device for cable laying in the power supply system of electrical equipment, a cable tray plays a role in protecting the cables laid in the cable tray and guiding the wire routing. A cable tray consists of a straight section of a tray or ladder, its bends, accessories, and supports and hangers, which form a continuous rigid structure system for supporting the cable line. A ladder-type cable tray is a rigid trapezoidal component composed of side edges and several crossbars. When constructing a cable tray, according to the requirements of the length or direction change of the laid cables, the straight section needs to be matched with horizontal bends, tees, cross tees and other fittings. Most of the bends of cable trays in the traditional market are right angles when it comes to angle connection. When pulling the cable, the cable will be bent at 90 degrees, which easily causes the wires inside the cable to break. And the pulling of the cable will cause the edges of the right-angle surface to be frequently rubbed, accelerating the wear and aging of the cable.

[0033] As Figure 1 , Figure 2 shown, the present utility model provides a cable tray tee connection structure for T-shaped connection between a cable tray and a transition tray, that is, the transition tray connects to the middle of the cable tray to connect the tray side plate 1. Specifically, the cable tray tee connection structure includes a tray side plate 1, two arc-shaped connectors, and two transition side plates 3. A docking port is provided on the tray side plate 1. The two transition side plates 3 are arranged side by side at the docking port. The two arc-shaped connectors are respectively arranged on both sides of the docking port. One end of each of the two arc-shaped connectors is respectively connected to the tray side plate 1 located on both sides of the docking port, and the other end of each of the two arc-shaped connectors is respectively connected to the two transition side plates 3. In the present utility model, the tray side plate 1 is a side plate on the cable tray. A docking port is provided on the tray side plate 1. The two arc-shaped connectors are respectively arranged on both sides of the docking port, and are connected between the tray side plate 1 and the transition side plate 3 through the arc-shaped connectors, making the transition between the cable tray and the transition tray smooth, with less resistance when the cable is pulled and dragged, smooth dragging, smooth bending of the cable, effectively avoiding damage to the insulating layer and bending fatigue of the battery core, and improving the service life of the cable.

[0034] For the arc-shaped connector, specifically, the arc-shaped connector is an arc-shaped side plate 2.

[0035] In some embodiments of the arc-shaped side plate 2, as Figure 3 shown, the upper parts at both ends of the arc-shaped side plate 2 are provided with first buckling parts 21 for respectively buckling the upper parts of the tray side plate 1 and the transition side plate 3. In this way, the arc-shaped side plate 2 can be buckled on the tray side plate 1 and the transition side plate 3, facilitating the connection of the arc-shaped side plate 2 to both the tray side plate 1 and the transition side plate 3 at the same time.

[0036] In some further embodiments of the arc-shaped side plate 2, as Figure 3As shown, lower parts at two ends of the arc-shaped side plate 2 are provided with limiting parts 22, and the two limiting parts 22 respectively extend towards the lower part of the bridge side plate 1 and the lower part of the adapter side plate 3 for limiting the position of the arc-shaped side plate 2.

[0037] The arc-shaped side plate 2 can be buckled on the bridge side plate 1 and the adapter side plate 3, and the lower part of the arc-shaped side plate 2 is limited by the limiting parts 22. In this way, the arc-shaped side plate 2 is limited up and down. Moreover, before locking the arc-shaped side plate 2 with the bridge side plate 1 and before locking the arc-shaped side plate 2 with the adapter side plate 3, the arc-shaped side plate 2 can be quickly disassembled and assembled, effectively improving the assembly efficiency.

[0038] In addition, the arc-shaped side plate 2 is buckled on the bridge side plate 1 and the adapter side plate 3 through the first buckling part 21 and the limiting parts 22. Usually, the slidability between the arc-shaped side plate 2 and the bridge side plate 1 is maintained, and the slidability between the arc-shaped side plate 2 and the adapter side plate 3 is also maintained. In this way, by moving the arc-shaped side plate 2, the buckling position of the first end of the arc-shaped side plate 2 with the bridge side plate 1 can be adjusted, thereby adjusting the width of the adapter bridge. By moving the arc-shaped side plate 2, the buckling position of the second end of the arc-shaped side plate 2 with the adapter side plate 3 can be adjusted, thereby adjusting the length of the adapter bridge. That is, by arranging the first buckling part 21 and the limiting parts 22 on the arc-shaped side plate 2, the adapter bridge has adjustability in width and length.

[0039] Of course, when the arc-shaped side plate 2 is provided with the first buckling part 21, the upper parts of the bridge side plate 1 and the adapter side plate 3 are also provided with matching structures. That is, the upper part of the bridge side plate 1 is provided with a first bending part matching with the first buckling part 21, and the upper part of the adapter side plate 3 is provided with a second bending part matching with the first buckling part 21.

[0040] In some embodiments of the bridge side plate 1 and the adapter side plate 3, as Figure 2 shown, a first longitudinal beam 11 is arranged inside the bridge side plate 1, the first longitudinal beam 11 passes through the docking port, a second longitudinal beam 31 is arranged inside the adapter side plate 3, the second longitudinal beam 31 extends to the docking port, and the second longitudinal beam 31 is connected to the first longitudinal beam 11. The bridge side plate 1 and the adapter side plate 3 are usually sheet metal structures. After their dimensions exceed a certain length, there is a problem of insufficient strength. However, the first longitudinal beam 11 and the second longitudinal beam 31 can improve the strength of the bridge side plate 1 and the adapter side plate 3. In addition, the second longitudinal beam 31 is connected to the first longitudinal beam 11, so that the second longitudinal beam 31 is supported, which is convenient for the second longitudinal beam 31 to carry and support the adapter side plate 3.

[0041] In some embodiments of the cable tray tee connection structure, such as Figure 1 、 Figure 2As shown, the cable tray tee connection structure further includes a steering buckle 4. One end of the steering buckle 4 is provided with a second buckling part, which is buckled on the first longitudinal beam 11 at the docking port, and the other end of the steering buckle 4 is provided with a supporting part. The second longitudinal beam 31 extends onto the supporting part. One end of the steering buckle 4 is buckled on the first longitudinal beam 11, and the other end supports the second longitudinal beam 31. In this way, after the steering buckle 4 is set, the second longitudinal beam 31 can be carried by the first longitudinal beam 11, and the fastening structure of the transfer bridge can be reduced, specifically, the fastening structure of the transfer side plate 3 can be reduced, the assembly efficiency can be improved, and the assembly difficulty can be reduced.

[0042] Specifically, as Figure 4 shown, the second buckling part includes a first side plate 41, a second side plate 42, an upper plate 43 and a buckling limiting plate 44. The first side plate 41 and the second side plate 42 are arranged side by side. The first side plate 41 is connected to the supporting part. The two ends of the upper plate 43 are respectively connected to the upper parts of the first side plate 41 and the second side plate 42. The buckling limiting plate 44 is arranged at the lower part of the second side plate 42 and extends towards the first side plate 41. The first side plate 41, the upper plate 43, the second side plate 42 and the buckling limiting plate 44 successively surround the first longitudinal beam 11. Among them, the buckling limiting plate 44 is located at the lower part of the second side plate 42 and extends towards the bottom of the first longitudinal beam 11, playing a role of protruding limitation, and the first side plate 41, the upper plate 43, the second side plate 42 and the buckling limiting plate 44 are elastically buckled and disassembled.

[0043] As Figure 4 shown, the supporting part includes a supporting plate 45 and two supporting limiting plates 46. The supporting plate 45 is connected to the second buckling part. The two supporting limiting plates 46 are respectively arranged on both sides of the supporting limiting plate 46. The second longitudinal beam 31 is carried by the supporting plate 45, and the positions of the ends of the second longitudinal beam 31 are limited by the two supporting limiting plates 46 to prevent the ends of the second longitudinal beam 31 from slipping off the supporting plate 45.

[0044] In addition, the first side plate 41 is connected to the supporting plate 45.

[0045] Furthermore, there is a problem of insufficient connection stability between the arc-shaped connecting piece and the bridge side plate 1, and between the arc-shaped connecting piece and the transfer side plate 3. Or rather, the buckling between the arc-shaped side plate 2 and the bridge side plate 1, and the buckling between the arc-shaped side plate 2 and the transfer side plate 3 are not sufficient to stably install the transfer bridge. Therefore, the cable tray tee connection structure further includes a number of locking pieces. Some locking pieces are arranged at the connection between the arc-shaped connecting piece and the bridge side plate 1 to fasten the arc-shaped connecting piece and the bridge side plate 1, and some locking pieces are arranged at the connection between the arc-shaped connecting piece and the transfer side plate 3 to fasten the arc-shaped connecting piece and the transfer side plate 3. Through the locking pieces, the stability between the arc-shaped connecting piece and the bridge side plate 1, and the stability between the arc-shaped connecting piece and the transfer side plate 3 are improved.

[0046] The above embodiments are only the preferred embodiments of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
