[0001] The present invention relates to the technical field of line management, and in particular to a multifunctional hub. Background Art

[0002] A hub is a pure hardware network underlying device. Its main function is to regenerate, shape and amplify the received signals to expand the transmission distance of the network, and at the same time concentrate all nodes on the node centered on it. It basically does not have the "intelligent memory" and "learning" capabilities similar to switches. In software development applications, hubs are often required due to the need to integrate and connect the signals of various electronic components.

The lower wall of the cover shell 15 is symmetrically fixed with two plug plates 20. The bottom shell 2 is provided with two slots 12 corresponding to the plug plates 20. The inner walls of the two slots 12 are fixedly provided with first springs 21. The two plug plates 20 squeeze the two first springs 21 respectively. The two slots 12 are also provided with limiting mechanisms corresponding to the plug plates 20. The limiting mechanisms include two card blocks 13. The side walls of the two slots 12 are provided with telescopic grooves 23 corresponding to the card blocks 13. The two card blocks 13 are respectively slidably arranged in the two telescopic grooves 23, and each card block 13 is connected to the telescopic groove 23 through a second spring 22.

After the terminal 3 is inserted, the handle 16 is rotated to drive the threaded rod 6 to rotate, thereby driving the slider 19 to slide in the slide groove 7, and then driving the top plate 5 to slide, tighten the terminal 3 to prevent the terminal 3 from loosening. After the top plate 5 is tightened, the plug plate 20 is put into the slot 12, and the cover shell 15 is covered until the block 13 is inserted into the slot to complete the installation and fixation of the cover shell 15, thereby achieving protection for the terminal 3. To avoid damage from collision or dust and water ingress, and to protect the stability of the connection of the terminal 3, when the terminal 3 needs to be pulled out, only the pull rod 14 needs to be pulled to drive the block 13 to slide out of the slot, thereby releasing the restriction on the plug board 20.
