When branching is required, the plug-in protective cover 2 can be easily opened to connect with the external plug connector 13, which has good scalability.

[0022] The first plug-in protective cover 3 is fixedly mounted on one end of the plug-in bus duct housing 1, the second plug connector 14 is located on the inner side of the first plug-in protective cover 3, the second plug-in protective cover 4 is fixedly mounted on the other end of the plug-in bus duct housing 1, and the first plug connector 12 is located on the inner side of the second plug-in protective cover 4.

[0023] The first plug-in protective cover 3 is symmetrically provided with a limiting slot 5 at one end away from the plug-in bus duct housing 1, and an insulating housing 10 is fixedly connected to the inner side of the first plug-in protective cover 3. The second plug-in protective cover 4 is symmetrically fixedly connected to a limiting rod 6 at the inner side of one end away from the plug-in bus duct housing 1. The limiting rod 6 and the limiting slot 5 are slidably connected.

The first plug connector 12 is designed as a pointed straight plate, and the second plug connector 14 is designed as a fork, and the first plug connector 12 and the second plug connector 14 are movably plugged in. During the connection process, the first plug connector 12 is plugged in and contacted with the inner side of the second plug connector 14, so that the plug-in bus duct housing 1 can be flexibly combined according to the length of the circuit laid as needed, and no connector is required.

[0024] The locking bolts 9 are symmetrically arranged, and are movably connected to the first plug-in protective cover 3 and the second plug-in protective cover 4 respectively.

The second plug connector 14 squeezes the first plug connector 12 located inside, strengthening the connection between the first plug connector 12 and the second plug connector 14. All the plug-in bus duct shells 1 are connected in sequence. When branching is required, the plug-in protective cover 2 is opened by external force, and then the plug-in components are plugged into the external plug connector 13 inside the insulating protective plate 7 for connection.
