with a binding post for indicating device, see in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, figure: wire coil 1, inner lead 2, integrated circuit 3, LED indicating device 4, wire seat 5, access wire 6, binding post body 7.
be embedded with wire coil 1 in binding post body 7, (wire coil 1 is preset when 7 injection mo(u)lding of binding post body; ) wire coil 1 is connected by inner lead 2 with integrated circuit 3, one end of integrated circuit 3 is connected with the LED indicating device 4 be placed in outside binding post body 7.
the wire diameter of the plain conductor of wire coil 1 and the number of turn look specification and the decision of terminal overall dimension of access wire 6 wire diameter in binding post body 7, the access wire diameter specification of wire 6 and the overall dimension hour of binding post body 7, the wire diameter of the plain conductor of wire coil 1 is little and the number of turn is many; When the overall dimension of the access wire diameter specification of wire 6 and binding post body 7 is large, the wire diameter of the plain conductor of wire coil 1 is large and the number of turn is few.Its aim is for LED indicating device provides enough induced currents.
the capacity of integrated circuit 3 looks specification and the decision of terminal overall dimension of binding post intrinsic access wire 6 wire diameter, and its aim is for LED indicating device provides enough stabilized power supplys.
wire coil 1 is set on wire seat 5; Wire seat 5 is built with access wire 6.Wire coil 1 is connected by inner lead 2 with integrated circuit 3.
integrated circuit 3 is power filter voltage regulating, micro integrated circuits.Integrated circuit 3 embeds in the insulation plastic cement of binding post body 7, and LED is placed in the table plane of binding post body 7.
one end of rectification circuit in integrated circuit is connected with wire coil, and the output of rectification circuit is connected with filter circuit, and the output of filter circuit is connected with voltage stabilizing circuit; The positive and negative electrode of circuit output end of pressure-stabilizing respectively with the resistance R in booster circuit
