Problems solved by technology
The first type is inconvenient for on-site installation and maintenance, and because the positions of different modules are different, the lengths of external cables that need to be provided cannot be uniform; the second type solves the problem of uniform lengths of external power cables, but the integration of power interface modules is not high, such as There are many PCB modules in the whole machine, which cannot be effectively configured. The number of configurations needs to be large, which takes up a lot of installation space and increases the cost.

The invention discloses a general power supply interface layer module of a railway signal system. The module includes a U-shaped groove-shaped structural member, a U-shaped plate and a front cover; the opening side of the U-shaped plate is fixed to the front cover. One side of the front cover is hinged with the opening side of the structural member; the inner surface of the structural member is provided with a first DIN guide rail, and the surface of the first DIN guide rail is provided with a first terminal piece, so The first terminal strip is detachably connected to the first DIN rail; the outer surface of the U-shaped board is provided with a second DIN rail, and the surface of the second DIN rail is provided with a second terminal strip, and the second terminal The piece is detachably connected with the second DIN rail. The invention enables the operator to connect the cables between the first terminal piece and the second terminal piece when configuring the cables. The space is small and the cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of railway communication equipment, in particular to a general power interface layer module of a railway signal system. Background technique [0002] In the field of railway communication signal products, the integration and modularization of PCB has been very perfect, but for the whole cabinet system level, there are two power supply design schemes for the system: one is to simply connect the power line to each PCB module; the other One is to simply install the terminal block on a sheet metal mounting plate to shunt the external cables to each PCB module. The first one is inconvenient for on-site installation and maintenance, and due to the different positions of different modules, the lengths of the external cables that need to be provided cannot be unified; the second one solves the problem of unified length of external power cables, but the integration of power interface modules is not high, such as The...
