Abstract
The utility model provides a voltage acquisition dissipation wiring terminal, comprising a 32-pin welding terminal plate, a 32-pin welding terminal cover, screws and 32 resistors; two pins of each resistor are respectively welded on the corresponding inner sides of the terminals of the 32-pin welding terminal plate and the 32-pin welding terminal cover, the 32-pin welding terminal cover is fixed on the 32-pin welding terminal plate by the screws. In the voltage acquisition dissipation wiring terminal, a dissipation resistor is arranged inside the terminal to dissipate voltage signals inside the terminal, so as to prevent high-voltage signals from entering the inside of a microcomputer monitoring system to damage an acquisition board card, and improve the system withstand voltage level; when in use, the resistors with different resistances are chosen according to the acquired different voltage signals, so as to realize dissipation of the voltage signals in different levels.
Description
Technical field
The utility model relates to a kind of distribution terminal, specifically, relates to a kind of voltage acquisition attenuation distribution terminal.
Background technology
Railway signal microcomputer is monitored product in use, because the voltage level difference that the different acquisition plate is gathered, maximum can reach more than the 2500V, because pcb board uses rectangular connector withstand voltage lower, have potential safety hazard, and after high-voltage signal enters collection plate, PCB layout will be restricted; For this reason, be badly in need of a kind of terminal to different stage voltage signal attenuation distribution.
Summary of the invention
The utility model is at the deficiencies in the prior art, and a kind of simple in structure, practical, voltage acquisition attenuation distribution terminal that reliability is high is provided.
The technical scheme that the utility model adopted is as follows: a kind of voltage acquisition attenuation distribution terminal, it comprises 32 pin welding ends daughter boards, 32 pin solder terminal covers, screw and 32 resistors, two pins of described resistor are welded on the corresponding described 32 pin welding ends daughter boards and the terminal inboard of described 32 pin solder terminal covers respectively, described 32 pin solder terminal covers by screw on described 32 pin welding ends daughter boards.
Described 32 pin welding ends daughter boards are respectively arranged with screw hole in two ends up and down.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, this voltage acquisition attenuation distribution terminal is installed on terminal inside with attenuation resistance, can carry out attenuation to voltage signal in terminal inside, avoid big voltage signal to enter of the damage of microcomputer detecting system inside, the withstand voltage rank of raising system to analog input card; During use,, select the resistor of different resistances, realize attenuation the voltage signal of different stage according to the voltage signal difference of gathering.
Description of drawings
Fig. 1 is the structural representation of facing of the present utility model;
Fig. 2 is a side-looking structural representation of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of voltage acquisition attenuation distribution terminal, it comprises 32 pin welding ends daughter boards, 1,32 pin solder terminal covers 2, thirty letter disk head screw 3 and 32 resistors 4;
The resistance of 32 resistors 4 has nothing in common with each other;
Two pins of each resistor 4 are welded on the corresponding described 32 pin welding ends daughter boards 1 and the terminal inboard of described 32 pin solder terminal covers 2 respectively, and described 32 pin solder terminal covers 2 are fixed on the described 32 pin welding ends daughter boards 1 by thirty letter disk head screw 3.
Described 32 pin welding ends daughter boards are respectively arranged with screw hole in two ends about in the of 1.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
