Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections. Busbar ducts have emerged as a new type of distribution conductor. The busbar duct system is a distribution device that efficiently transmits current. It is particularly suitable for the economical and reasonable wiring needs of increasingly tall buildings and large-scale factories. Therefore, it is widely used in the connection between low-voltage distribution panels and large and medium-sized loads, such as modern workshops, factory buildings and high-rise buildings. It is particularly suitable for workshops with diverse products and dense equipment.

Fixed plates 112 extending along the height direction of the shell 11 are symmetrically provided on the left and right sides of the shell 11 port between the two docking plates 111. A plurality of evenly distributed mounting grooves 113 are opened on the fixed plate 112, and a connecting component 2 and a connecting cover plate 3 are detachably provided between two adjacent duct bodies 1.

[0023] refer to Figure 3-Figure 4The connecting component 2 includes a connecting base plate 201, both ends of which are folded upward to form symmetrical connecting side plates 202. The top of the inner wall of the connecting side plate 202 is fixedly connected to a connecting plate 203, and the top end face of the connecting plate 203 is fixedly connected to a reinforcing plate 204. The connecting side plates 202 are symmetrically provided with mounting plates 205 that fit into the mounting grooves 113 on both sides. Through the arrangement of the mounting plates 205 and the mounting grooves 113, the connecting component 2 is initially fixedly connected to the two adjacent wire trough bodies 1. A ceramic block 206 is provided on the top end face of the connecting base plate 201. The ceramic block 206 has excellent insulation performance and can effectively prevent the conductive clip 208 from leaking electricity. The top end face of the ceramic block 206 is provided with a card groove 207 corresponding to the conductor 12 one by one, and a conductive clip 208 with a U-shaped cross-section is fixed in the card groove 207.

[0024] refer to Figure 5 , one end of the connecting cover plate 3 is symmetrically provided with a docking groove 301 for the docking plate 111 to be plugged in when the two adjacent wire trough bodies 1 are connected. Through the setting of the docking groove 301 and the docking plate 111, the connecting cover plate 3 is initially fixedly connected to the two adjacent wire trough bodies 1. A reinforcement groove 302 for the reinforcement plate 204 to be plugged in is provided on the connecting cover plate 3 inside the docking groove 301. Through the setting of the reinforcement groove 302 and the reinforcement plate 204, when the connecting cover plate 3 is connected to the two adjacent wire trough bodies 1, the connection between the connecting cover plate 3 and the connecting component 2 is reinforced. The two ends of the connecting cover plate 3 are symmetrically hingedly connected with a first fastening plate 303. The first fastening plate 303 is slidably connected to a sliding rod 304 at one end away from the connecting cover plate 3. One end of the sliding rod 304 is slidably connected to the first fastening plate 303, and the other end of the sliding rod 304 is fixedly connected to the second fastening plate 305.

[0025] Furthermore, a buffer spring 306 is sleeved on the outer side of the sliding rod 304 , one end of the buffer spring 306 is fixedly connected to the first fastening plate 303 , and the other end of the buffer spring 306 is fixedly connected to the second fastening plate 305 .

[0026] Furthermore, a positioning plate 307 is provided at the bottom of the inner wall of the second fastening plate 305, and a reinforcing block 308 is provided on the top end face of the positioning plate 307. A positioning groove 209 is provided on the outer wall of the connecting side plate 202 for the positioning plate 307 to be inserted into after the second fastening plate 305 is stretched.

[0027] It should be noted that the height of the positioning groove 209 is greater than or equal to the sum of the heights of the positioning plate 307 and the reinforcement block 308 , so that the positioning plate 307 and the reinforcement block 308 can be inserted into the positioning groove 209 during installation.

[0028] The working principle of this utility model:

[0029] When laying the bus duct, first align the conductors 12 on the two adjacent duct bodies 1 with the card slots 207 on the connecting component 2 and plug them into each other. The card slots 207 are fixed with conductive clips 208, so that the conductive clips 208 realize the connection between the conductors 12 on the two adjacent duct bodies 1. When the conductors 12 are plugged into the card slots 207, the mounting plate 205 on the connecting component 2 is plugged into the mounting slots 113 on the two adjacent duct bodies 1, so that the connecting component 2 is initially fixedly connected to the two adjacent duct bodies 1. Then, the docking groove 301 on the connecting cover plate 3 is aligned with the docking plate 111 on the two adjacent duct bodies 1 for plugging. At the same time, the reinforcing plate 204 on the connecting component 2 is plugged into the reinforcement groove 302 on the connecting cover plate 3, so that the connecting cover plate 3 is initially fixedly connected to the two adjacent duct bodies 1 and the connecting component 2. When the first fastening plate 303 on the connecting cover 3 is rotated and the second fastening plate 305 is stretched, the buffer spring 306 and the slide bar 304 are also stretched, and the buffer spring 306 undergoes elastic deformation. When it is stretched until the positioning plate 307 and the reinforcement block 308 are aligned with the positioning groove 209 on the connecting component 2, the positioning plate 307 and the reinforcement block 308 are inserted into the positioning groove 209. Under the elastic action of the buffer spring 306, the buffer spring 306 contracts to generate a reset elastic force to drive the slide bar 304 to contract, so that the positioning plate 307 and the reinforcement block 308 move upward synchronously until the reinforcement block 308 is fully engaged in the reinforcement groove 210. At this time, the connecting cover 3 is firmly installed on the connecting component 2, further strengthening the fastening between the connecting cover 3 and the connecting component 2 and the adjacent two wire trough bodies 1, thereby ensuring that the adjacent two wire trough bodies 1 are firmly connected.

[0030] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
