One side of the box cover 200 is provided with a hinge (not shown in the figure), which is used for hinged connection with the box body.

Please refer to FIGS. 1-3 , and the assembly connection relationship between the box body 100 , the box cover 200 , the fixing frame 400 and the connection terminals 510 , 520 , 530 will be described below with reference to FIGS. 1-3 . The bottom wall 130 of the box body 400 is provided with two sets of six through holes 131 and two sets of connection terminals 510 , 520 , 530 respectively disposed in each through hole. The backboard 120 of the box body 400 is provided with two sets of four fixing frames 400 in total.

The fixing part of the fixing frame 400 has a through hole, which can be fixed on the backplane 120 in the box body 100 through the through hole by a screw, and the clamping groove part is used to compress and fix the passive device on the backplane 120 . The quantity and installation method of the fixing frame 400 can be adjusted according to the actual structure and quantity of passive components.

The connecting terminals 510, 520, 530 are inserted into the through hole 131 of the bottom wall 130 through their box body ends, and their flanges are attached to the end surface of the through hole 131 (that is, the outer surface of the box of the bottom wall 130 surrounding the opening of the through hole 131), And the flange is fastened to the box outer surface of the bottom wall 130 by screws passing through the mounting holes on the flange, and a gasket or sealant (not shown) is arranged between the flange and the box wall to realize a sealed connection.

The box cover 200 is hinged on the side wall of the box body 100 by its hinge. When the box cover 200 is closed, the box cover 200 will squeeze the gasket provided around the opening 110 of the box body 100, thereby making a good seal between the two. Effectively prevent outside rain and snow from entering.

The box body 100 and the box cover 200 can form a closed chamber, which can accommodate the entire passive device, thereby basically isolating the direct contact of the passive device and its interface with water. The connection terminals 510, 520, 530 are arranged on the bottom wall 130 of the box body 100, and the box body itself can prevent rainwater from falling to the connection terminals 510, 520, 530, so the connection terminals 510, 520, 530 can pass through ordinary waterproofing such as waterproof tape. A good waterproof effect can be achieved with only one measure, and the installation or removal is easier.

The present invention also provides a passive device wiring system. Please refer to FIG. 2-3 together. An embodiment of the passive device wiring system will be described below with reference to FIG. 2-3.

In this embodiment, the passive device connection system includes a passive device connection box 1 , a power splitter 600 and an installation frame 300 .

Wherein, the passive device junction box 1 is a junction box provided by the present invention, and its specific structure can refer to the detailed description above, and will not be repeated here.

The mounting frame 300 is in the shape of a long plate and is provided with mounting slots. There are two mounting brackets 300 and they are respectively connected to two sides of the top and bottom of the backboard 120 of the box body 100 for fixing the box body 100 on the workplace. In an optional embodiment, the installation frame 300 may also be installed on the side walls 150 and 160 of the box back panel 120 .

The power splitter 600 is installed in the box body 100 through the fixing frame 400 . The power splitter 600 has a bus interface 630 and two branching interfaces 610 and 620. The interface 610 is connected to the terminal 510 through a cable 710, the interface 620 is connected to the terminal 520 through a cable 720, and the interface 630 is connected to the wiring terminal through a cable 730. Terminal 530 is connected. The outside ends of the terminals 510, 520 and 530 are used to connect with feeders outside the box or other equipment. Taking the connection terminal 510 as an example, the interface 630 of the power divider 600 is connected to the box end 532 of the connection terminal 530 through the cable 730, and the outside end 531 of the connection terminal 530 is used to connect with a feeder or other equipment.

In this embodiment, the power divider 600 is a power divider with three interfaces. In other optional embodiments, the power divider 600 can also have four interfaces, or the power divider 600 can also be a coupler, etc. other passive components.

Since the power divider 600 and its connecting parts with the terminals 510 , 520 , 530 are all located inside the box body 100 , rain and snow can be effectively prevented from entering the power divider 600 through the terminals 510 , 520 , 530 .

In addition, the connection terminals 510, 520, 530 are arranged on the bottom wall 130 of the box body 100, and the box body itself can prevent rainwater from falling to the connection terminals 510, 520, 530, so the connection terminals 510, 520, 530 can be connected through, for example, waterproof tape. Ordinary waterproof measures can achieve a good waterproof effect, and it is easier to install or disassemble.

Moreover, since the junctions between the power divider 600 and the terminals 510, 520, and 530 are in an observable state, wiring errors can be effectively prevented during the wiring process. Even if a wiring error occurs, it is easy to visually check out the wrong part , The process of replacing wiring or passive components is also more convenient than cement sealing.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any person familiar with the technical field can easily think of various Equivalent modifications or replacements shall all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
