Its main function is to extend the distance of network transmission by retransmitting or forwarding data signals. A repeater is a network device that regenerates and restores signals: a physical layer device in the OSI model. A repeater is used to extend the network distance in a LAN environment, but it is a network interconnection device that operates on the physical layer of OSI. A repeater has the function of amplifying and regenerating signals on the line, and is used to extend the length of a LAN segment.

[0003] When the repeater is installed, it is fixed by means of a mounting frame integrally formed with the repeater housing and bolts. The mounting frame and the repeater housing are integrally formed, and the bolts need to be repeatedly disassembled and tightened during subsequent maintenance and disassembly, which can easily cause failure of the bolt threads and affect the stability of the installation effect of the repeater. In addition, the display screen on the repeater is external and lacks an effective protective mechanism. It is easily damaged by contact and impact, affecting normal use. Utility Model Content
