Abstract
The utility model relates to a distributor for high-speed motor train units, which is provided with relay mounting plates in multiple layers. Each layer of the relay mounting plates is formed by a plurality of relays welded onto a circuit board, the circuit boards are inserted onto a bottom mainboard of the distributor by the aid of guide rails, the guide rails are fixed on a frame, the frame is formed in a riveted manner after being bended, pressing plates used for fixing the relay mounting plates in the frame are arranged on the upper portion of the frame, and pressing strips are adhered to the pressing plates. The relays are stereoscopically mounted, an original relay single-substrate mounting method is replaced by a multiple circuit board inserting type mounting method, and accordingly, mounting space of the distributor on the high-speed motor units is greatly saved. Meanwhile, guide rails are inserted during mounting of the circuit boards, thereby bringing convenience for maintaining.
Description
Technical field
The utility model relates to a kind of distribution board, especially a kind of main distribution board that is used for the high-speed railway motor train unit.
Background technology
Main distribution board is used on the EMU train.Various logic loop during train operation that inner numerous components and parts are integrated has disposed signal input, output interface.And these functions realize with the tongue tube power relay ON TRAINS, the dry-reed relay of using on the train is on distribution board or the power distribution cabinet plate and installs at present, the shortcoming of this mounting means is: relay is installed for the mounting panel individual layer, and it installs how much quantity is to be decided by the vehicle body space size; For the higher motor train unit of complexity, needed number of logic cells is quite huge.
The utility model content
The technical problems to be solved in the utility model is: propose a kind of a kind of EMU distribution board that relay is carried out the three-dimensional installation.
The technical scheme that the utility model adopted is: a kind of EMU distribution board, has multilayer relay mounting panel, described each layer relay mounting panel is welded on the wiring board by a plurality of relays, wiring board is inserted on the mainboard of distribution board bottom by guide rail, guide rail is fixed on the framework, described framework is shaped through bending back staking, and framework upper is provided with the relay mounting panel is fixed on pressing plate in the framework, is pasted with press strip on the described pressing plate.
A kind of EMU described in the utility model also includes with distribution board: installation base plate; Velocity transducer resistance; Diode panel; Attachment unit interface CN1-5; The logic printed substrate is integrated; Out connector interfaces such as head identification light signal; Surge protective device; The SMITT relay; Separated time terminal board etc., described relay mounting panel be arranged on the logic printed substrate integrated on.
The material of guide rail described in the utility model is a Merlon, and the framework material is a steel plate, and the material of press strip is a rubber.
The beneficial effects of the utility model are: relay has been carried out the three-dimensional installation, original monobasal formula method for installing relay has been changed into multi-line plate plug-in type install, this has saved the installing space of main distribution board on motor train unit greatly.Simultaneously when wiring board is installed, adopt the insertion guide rail, made things convenient for maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the perspective view of Fig. 1;
Fig. 3 is an operation principle block diagram of the present utility model;
Among the figure: 1～3, screw fastener; 4, pressing plate; 5, press strip; 6, guide rail; 7, framework; 8, ear handle; 9, wiring board; 10, relay.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, 2, a kind of EMU distribution board, has multilayer relay mounting panel, described each layer relay mounting panel is welded on the wiring board 9 by a plurality of relays 10, wiring board 9 is inserted on the mainboard of distribution board bottom by guide rail 6, and guide rail 6 is fixed on the framework 7, and described framework 7 is shaped through bending back staking, framework 7 tops are provided with relay 10 mounting panels are fixed on pressing plate 4 in the framework, are pasted with press strip 5 on the described pressing plate 4.
The quantity of relay is distributed according to actual conditions, mainly is to distribute by function.The material of guide rail 6 is a Merlon, and framework 7 materials are steel plate, is shaped through staking after the bending, and the required precision of framework 7 is than higher.When the plug wiring board, for the strength of guaranteeing to insert adopts ear handle.Pressing plate is fixed on the framework by using screw fastener.
Described main distribution board also includes: installation base plate; Velocity transducer resistance; Diode panel; Attachment unit interface CN1-5; The logic printed substrate is integrated; Out connector interfaces such as head identification light signal; Surge protective device; The SMITT relay; Separated time terminal board etc., described relay mounting panel be arranged on the logic printed substrate integrated on.
As can be seen from Figure 1, present embodiment has just been used 7 wiring boards altogether, and the relay of every wiring board is installed quantity all more than 20, and this has saved the installing space of main distribution board on motor train unit greatly.Simultaneously when wiring board is installed, adopt the insertion guide rail, made things convenient for maintenance.
As shown in Figure 3, the output interface of signal input interface and execution result adopts 7 50 core connectors, and totally 350 interfaces can define the input and the output of each interface voluntarily according to actual conditions.After the signal input, with operation result output, wherein a part of output signal is the identification light signal after elapsed time relay and the logic determines.What wherein the time relay adopted is the OMRON time relay.When the components and parts in logic determines district make a mistake, in emergency circumstances can move this by the closing promptly of short switch of parallel connection, this moment, logic switch was no longer had an effect.
What describe in the above specification is embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of utility model.
