A single functional module on a passenger service unit (PSU) can be quickly and easily disassembled and installed to another passenger service unit. (PSU), while the integrated modular design is relatively lighter and requires relatively high reliability. Once a single functional module on a passenger service unit (PSU) fails, it may cause the entire passenger service unit (PSU) to require Replace it.

The layout of the passenger service unit (PSU) needs to be comprehensively considered in terms of safety, functionality, economy, and aesthetics.

It can be clearly seen from Figure 2 that a significant feature of the present invention is that the connecting device adopts a modular design, which is connected to a series of evenly distributed rails on the passenger service unit (PSU) rails (including the outer rail OGU and the inner rail IGU). The openings (including the outer rail opening OOP and the inner rail opening IOP) correspond to each other, and the sizes of the plurality of openings are the same as each other.

Next, please refer to FIG. 3, which shows a schematic diagram of the structure of the connecting device of the present invention. Specifically, as shown in the figure, the connecting device of the present invention is used to connect a panel and a guide rail, and the connecting device includes a connecting module 10 and an elastic block 20. The connection module 10 includes a hook 110, a rotating shaft 120 and a torsion spring 130. The panel 30 has a vertical reinforcement stopper 310.
