Abstract
The utility model relates to an indication and simulation device for the switching-on and the switching-off of a relay, which is characterized by comprising a connector, cables and signal indication lamps, wherein the signal indication lamps are connected with the connector by the cables, and the number of the signal indication lamps corresponds to the number of the contacts of the relay. The utility model can conveniently and intuitively indicate the actual working conditions of the switching-on and the switching-off of the contacts of the relay. The simulation device is simple to operate, has small volume, is convenient to carry and store and enhances the working efficiency and quality greatly.
Description
Technical field
The utility model relates to a kind of test unit of relay on-off indication usefulness, especially can indicate the real work situation of relay contact closure and disconnection intuitively, exactly.
Background technology
The method of testing of relay contact working condition commonly used is to use multimeter to carry out manual measurement method, the method be applicable to under the few situation of quantity to the test of relay working condition, when needs detect the working condition of relay in enormous quantities, the method of this hand dipping is not only time-consuming but also require great effort, display result is also directly perceived inadequately simultaneously, brings certain difficulty for the test of relay.
The utility model content
Technical problem to be solved in the utility model is directly perceived, the problem that wastes time and energy that exists when overcoming existing relay test, thereby provides a kind of directly perceived, convenient, time saving and energy saving and can indicate the analogue means of relay working condition exactly.
For solving the problems of the technologies described above, the utility model provides a kind of relay on-off instruction simulation device, it is characterized in that: comprise connector, cable, signal lamp, signal lamp links to each other with connector by cable, and signal lamp quantity is corresponding with the relay contact number.
The utility model can indicate the real work situation of relay contact closure and disconnection easily, intuitively, and this simulating plant operations is simple, volume is small and exquisite, it is convenient to carry, take care of, and has greatly improved work efficiency and quality.
Description of drawings
Accompanying drawing is a relay instruction simulation apparatus structure synoptic diagram.
Embodiment
With reference to accompanying drawing, the utility model comprises connector 1, cable 2, signal lamp I 3, signal lamp II 4, signal lamp III5, signal lamp I 3, signal lamp II 4, signal lamp III5 pass through separately respectively, and cable 2 links to each other with connector 1.
Carrying out relay working condition when test, only need connector 1 is connected to the relay out connector, during relay contact closure, send electricity to signal lamp by cable 2, signal lamp is lighted-the indicating contacts closure; When relay contact disconnected, signal lamp extinguished-the indicating contacts disconnection.In addition, be provided with 3 signal lamps at 3 contacts of relay, guarantee that contact 1 is corresponding with signal lamp I 3, contact 2 is corresponding with signal lamp II 4, contact 3 is corresponding with signal lamp III5, simultaneously, cable 2 length that signal lamp I 3, signal lamp II 4, signal lamp III5 link to each other with connector 1 increase successively, guarantee can intuitively, clearly recognize relay contact 1,2,3 real work situations in certain distance.Realized detection to each contact working condition of relay.
