[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0021] This specification provides a T-connection terminal box installed above the bridge. Figure 1As shown, the box body 1 includes a terminal installation area 11, a first wiring area 12 and a second wiring area 13; the terminal installation area 11 is arranged between the first wiring area 12 and the second wiring area 13; the first wiring area 12 and the second wiring area 13 are open structures that run through the front and back of the box body 1; and connection mechanisms connected to the bridge are arranged on both sides of the box body 1. In a possible implementation, the first wiring area 12, the terminal installation area 11 and the second wiring area 13 are arranged in sequence from top to bottom in the box body. Among them, the terminal installation area 11 is installed with a JXT1 type T-connection terminal (either a JXT2 type T-connection terminal or a terminal block), and the box body adopts a 1.0MM thick metal box body. In another possible implementation, please refer to Figure 2 As shown, the connection mechanism includes a connecting arm 2, at least one arm 2 is provided on each side of the box 1, and a plurality of bolt holes 21 are provided on the arm 2. When in use, through holes are respectively opened on both sides of the box and both sides of the bridge, and then the box arms are connected by bolts, and then the arms are connected to the bridge.

[0022] When using, please refer to Figure 3 As shown, after the box is connected to the bridge, the cable L can be routed from the bridge and enter the first routing area or the second routing area through the back of the box and then connected to the terminal, reducing the turning radius of the cable and reducing the space occupied during connection. In addition to retaining the T-connection area of ​​the traditional T-junction box, the T-junction box is divided into three sections, upper, middle and lower, according to the installation method of the T-junction box. The upper and lower sections are for cable entry and exit. After closing the box door, the T-connected cables are not exposed. Save shaft space, multiple T-junction boxes can be arranged vertically along the bridge to save space.

[0023] In a preferred implementation, see Figure 4 As shown, a removable first partition 3 is provided between the first wiring area 12 and the terminal installation area 11, and a first through hole for passing the cable is provided on the first partition 3, and a slide groove 4 for plugging the partition is provided on both sides of the box body. When in use, after passing the cable through the through hole, the first partition is inserted into the slide groove. The purpose of preventing foreign matter from entering the terminal installation area is achieved. The connection method of the second partition is the same as that of the first partition, and will not be repeated here.

[0024] In a preferred implementation, see Figure 5 As shown, ear plates 5 are respectively provided on the front sides of both ends of the first partition 3, and the first partition 3 is fixedly connected to the box body 1 through the ear plates 5. When in use, the box body is correspondingly provided with screw holes, and after the first partition 3 is inserted into the slide slot, the ear plates are fastened to the box body by screws, thereby fixing the first partition to prevent the first partition from moving during use.

[0025] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0026] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
