Embodiment
Illustrate by reference to the accompanying drawings embodiment of the present utility model.
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, on display 6, be connected with electric connector 14, at another connection terminal of machine tool control transformer 3, be connected with testing needle 13.
Verifying unit also comprises fuse 1 and protection switch 2, and alternating current is connected with machine tool control transformer 3 with protection switch 2 by fuse 1 successively.Fuse model is optional, and with RD-10A, protection switch can be selected air switch, and model is DZ47-15/1, and fuse and protection switch shield.
Described verifying unit is also provided with potentiometer 4, and commutation diode 9 is connected with display 6 by potentiometer 4.By potentiometer, change the DC voltage value of commutation diode output, 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 socket 7,20 core sockets 8 or 56 core sockets 5.
Principle of work: 220V, 50HZ alternating current are passed through to lathe transformer, transformer model is BT-220V/36V, transformer is converted to 36V alternating current by 220V, 50HZ alternating current, alternating current is again by commutation diode, and it is 36 * 0.45=16.2V that the commutation diode half-wave rectification that model is 2PD5E obtains output dc voltage.DC voltage is again through potentiometer W, and it is 15V that the potentiometer that model is WXD3 is adjusted into output dc voltage, as display screen power supply.In figure, fuse model is that RD-10A and air switch model are that DZ47-15/1 shields.
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 the unit of display on each display screen of SS3A.In this device, show that maximum demonstration amount is that 56 cores need 56 units of display.Therefore adopt 2 SS3A type locomotive display screens as display device (being called for short X1/X2), display screen X1 is used 3*10=30 the unit of display, display screen X2 is used 2*10+6=26 the unit of display, by displaying contents maintenance change, be followed successively by 1/A1,1/A2,1/A3,1/A4,5/B1,6/B2 ... 20/E4 ... 56/P4.By processes and displays content and socket point, set up one-to-one relationship: 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: in device, 56 core sockets should remove coding, to reach versatility, is reliably connected with tested 56 core plugs (band coding).2, make plug/socket conversion line, reach the object (expanding check and correction plug/socket line to by proofreading plug cord) of the scope of expansion instrument use.
