Embodiment 1
[0031] like Figure 1 to Figure 6 As shown, a rail vehicle control relay panel includes a main frame. The main frame includes a panel mounting frame 1 and a sub-board mounting frame 2 . The sub-board mounting frame 2 protrudes from the panel mounting frame 1 .
[0032] The panel installation framework 1 includes a square box body, the bottom surface of which is a detachable bottom plate, the motherboard 3 is bolted into the square box body, and the bottom plate is provided to facilitate the installation and disassembly of the motherboard 3 .
[0033] A sub-board installation framework 2 is arranged on one side of the square box body. The sub-board installation framework 2 protrudes from the panel installation framework 1 and is perpendicular to it. The sub-board installation framework 2 includes a cuboid frame, and the cuboid frame and the panel installation framework 1 are integrated. , multiple groups of chute assemblies 17 for inserting the sub-board assembly 4 are arranged...
Embodiment 2
[0047] like Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that a plurality of first connectors 9 are also provided on the panel mounting frame 1 , and some sub-board assemblies 4 in multiple groups of sub-board assemblies 4 pass through third connectors 11 It is electrically connected with the motherboard 3 and outputted through the first connector 9 of the motherboard 3 , and the other sub-board components 4 are electrically connected with the first connector 9 on the panel mounting frame 1 through wires 12 . Sufficient length is reserved for the wire 12, and the wire can be connected to the sub-board assembly 4 smoothly and conveniently after the sub-board assembly 4 is removed.
[0048] Since the motherboard 3 is a printed circuit board, its routing is fixed, so electrical components such as relays 8 that are determined to be used or not changed (general) are arranged on the sub-board assembly 4 connected to the motherboard 3, according to ...
