All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The present utility model provides an I/O function board mounting unit 100. The socket model standard of the function board 110 is expanded by using the adapter board 120, and meanwhile, the structural installation relation between the adapter board 120 and the function board 110 is optimized, so that the adapter board 120 and the function board 110 are combined into the I/O function board assembly unit 100 convenient to install. The switching mode of adding bridging equipment in the prior art is replaced, the structure is simpler and more compact, and the installation and the disassembly are more convenient.
Referring to fig. 1 and 2 for exemplary purposes, fig. 1 is a schematic diagram of an I/O board mount unit 100 in one embodiment. The I/O function board, assembly unit 100 includes a function board 110, an adapter board 120, a panel 130, and a guide rail 140.

The panel 130 is fixedly connected with the adapter plate 120 and the functional board 110 at the same time, and the guide rail 140 is used for sliding the functional board 110 and the adapter plate 120.
For example, referring to fig. 2, in the above-mentioned mounting structure, the adaptor board 120 and the functional board 110 are in parallel butt joint, the panel 130 is simultaneously in vertical butt joint with the functional board 110 and the adaptor board 120, and the three are connected as a whole and then are inserted and slid through the guide rail 140.
Meanwhile, the arrangement of the adapter plate 120 enables the terminals for signal input and output of the functional board 110 to be arranged on the same side, so that signal transfer is more convenient and layout is reasonable. The terminal is selected to be compatible with industry specifications. In the mounting structure, two types of connectors are simultaneously arranged, so that different connection standards can be met, and different functions are realized. The panel 130, the functional board 110, and the adapter board 120 are fixedly connected with each other as a whole, so that the structure is more stable after installation, and no mutual shaking occurs. The guide rail 140 provides a moving range for the whole structure, so that push-pull installation of the I/O function board assembly unit 100 can be realized, and the I/O function board assembly unit can be directly pushed or pulled out relative to the host 200, thereby facilitating installation and detachment.
