Embodiment
Specify by reference to the accompanying drawings embodiments of the present invention.
Locomotive connector wire harness verifying unit, comprise machine tool control transformer 3, commutation diode 9, display 6, electric connector 14 and testing needle 13, alternating current passes into machine tool control transformer 3, a connection terminal of machine tool control transformer 3 by electric wire after commutation diode 9 half-wave rectification, be connected with display 6 again, be connected with electric connector 14 on the display 6, be connected with testing needle 13 at another connection terminal of machine tool control transformer 3.
Verifying unit also comprises fuse 1 and protection switch 2, and alternating current is connected with protection switch and is connected with machine tool control transformer 3 by fuse 1 successively.The optional RD-10A that uses of fuse model, protection switch can be selected air switch, and model is DZ47-15/1, and fuse and protection switch shield.
Described verifying unit also is provided with potentiometer 4, and commutation diode 9 is connected with display 6 by potentiometer 4.Change the dc voltage value that commutation diode is exported by potentiometer, to mate various displays.
Described display 6 is engine display, and model is that SS3A type locomotive display screen is as display device.
Described electric connector 14 is multi-core socket.
Described multi-core socket is a kind of in 10 core sockets 7,20 core sockets 8 or the 56 core sockets 5.
Principle of work: 220V, 50HZ alternating current are passed through the lathe transformer, the transformer model is BT-220V/36V, transformer is converted to the 36V alternating current with 220V, 50HZ alternating current, alternating current is again by commutation diode, and model is that to obtain output dc voltage be 36 * 0.45=16.2V to the commutation diode half-wave rectification of 2PD5E.DC voltage is again through potentiometer W, model be the potentiometer of WXD3 to be adjusted into output dc voltage be 15V, as the display screen power supply.The fuse model is that RD-10A and air switch model are that DZ47-15/1 shields among the figure.
Displaying principle: adopt SS3A type locomotive display screen as display device, improve with 56 cores, 20 cores, 10 core socket/points and set up one-to-one relationship, total 4*10=40 unit of display on each display screen of SS3A.Show in this device that maximum demonstration amount is that 56 cores need 56 units of display.So adopt 2 SS3A type locomotive display screens as display device (being called for short X1/X2), display screen X1 uses 3*10=30 the unit of display, display screen X2 uses 2*10+6=26 the unit of display, with displaying contents maintenance change, be followed successively by 1/A1,1/A2,1/A3,1/A4,5/B1,6/B2 ... 20/E4 ... 56/P4.Set up one-to-one relationship by processes and displays content and socket/point: 1 ... 10 and 10 core socket/points are set up one-to-one relationship; 1 ... 20 and 20 core socket/points are set up one-to-one relationship; A1 ... P4 and 56 core socket/points are set up one-to-one relationship, utilize testing needle to detect tested connector, and display screen shows tested connector current potential.
Application notice: 56 core sockets should remove coding in the device, to reach versatility, reliably are connected with tested 56 core plugs (band coding).2, make the plug/socket conversion line, reach the purpose (expanding check and correction plug/socket line to by proofreading plug cord) of the scope of expansion instrument use.
