Embodiment 1

[0024] Working principle: Pass 220V, 50HZ AC power through the machine tool transformer, the transformer model is BT-220V / 36V, the transformer converts 220V, 50HZ AC power into 36V AC power, and the AC power passes through the rectifier diode, and the rectifier diode model 2PD5E is half-wave rectified to obtain the output DC The voltage is 36*0.45=16.2V. The DC voltage is then adjusted by the potentiometer W, and the potentiometer of the model WXD3 is adjusted to output a DC voltage of 15V, which is used as a power supply for the display screen. In the figure, the fuse model is RD-10A and the air switch model is DZ47-15 / 1 for protection.

[0025] Display principle: SS3A type locomotive display screen is used as the display device, and a one-to-one correspondence relationship is established with 56-pin, 20-pin, and 10-pin socket / plug points. There are 4*10=40 display units on each display screen of SS3A. In this device, the maximum display quantity displayed is 56 cores and 56...

Abstract

The invention discloses a correction device for a wire harness of a locomotive connector. The correction device comprises a machine-tool control transformer, a rectifying diode, a display, an electric connector and a test needle, wherein an alternating current is connected into the machine-tool control transformer; one connecting terminal of the machine-tool control transformer passes through an electric wire, subjected to the half-wave rectification by the rectifying diode, and then connected with the display; the electric connector is connected with the display; the other connecting terminal of the machine-tool control transformer is connected with the test needle. The device is capable of rapidly detecting the correctness of the wire size of the wire harness, thus improving the working efficiency.

Description

technical field [0001] The invention relates to a calibration of a locomotive connector wire harness, in particular to a device for calibrating a locomotive connector wire harness. Background technique [0002] Locomotive connectors (56-pin, 20-pin, 10-pin socket / plug) are widely used in locomotive control lines. How to simply, quickly and accurately calibrate the correctness of the new connector (socket / plug) harness wire number is an important task that needs to be solved urgently in the manufacture and maintenance of electrical parts of locomotives. The existing technology adopts the test lamp calibration line, which needs 2 people to work together, which has low efficiency and high failure rate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wiring harness checking device for a locomotive connector, which can quickly detect the correctness of the wiring harness numbers and improve work efficiency. ...
