Abstract
The utility model relates to a transparent type electromagnetic relay, which comprises an electromagnetic system, a contact system, a base and a casing, wherein the base and the casing are used for fixing the electromagnetic system and the contact system. The electromagnetic system further comprises a coil in parallel connection with light-emitting diodes. The casing is transparent. Compared with the prior art, the transparent type electromagnetic relay has the advantages that two ends of the coil are in parallel connection with the light-emitting diodes so that when the coil is free of faults and the electromagnetic relay works normally, the light-emitting diodes emit light by means of current on two ends.
Description
Technical field
The utility model relates to a kind of relay, particularly a kind of transparent mode electromagnetic relay.
Background technology
Relay is a kind of electronic control device; It has control system and Be Controlled system; Usually be applied in the automatic control circuit; Be actually a kind of " automatic switch " that remove to control big electric current with less current, so in circuit, play effects such as automatic adjusting, safeguard protection, change-over circuit.
Existing electromagnetic relay generally comprises bobbin, base plate and the case of electromagnetic system and contact system and fixing these electromagnetic systems and contact system; Electromagnetic system comprises iron core, coil, yoke, armature, and contact system comprises moving contact, often opens electric shock and normally-closed contact, lead wire etc.Cause its coil to open circuit owing to the frequent practicality of relay or because of making reason, existing case is opaque material and processes, and therefore can't judge the quality of relay from outward appearance, and this has caused inconvenience for eliminating circuit obstacle.
Summary of the invention
The utility model technical problem to be solved is to overcome the above-mentioned defective of prior art and a kind of electromagnetic relay whether it works of directly judging is provided, to reach the convenient whether operate as normal of electromagnetic relay of confirming.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The transparent mode electromagnetic relay comprises that electromagnetic system and contact system reach the pedestal and the case of fixing these electromagnetic systems and contact system, and electromagnetic system comprises coil again, and light-emitting diode and coils from parallel connection of coils, described case are transparent casing.
The pin of described coil is provided with the fixedly breach of light-emitting diode one pin.
Compared with prior art, the beneficial effect of the utility model is: since in coil two ends parallel connections light-emitting diode, therefore do not have fault when coil, during the electromagnetic relay operate as normal, light-emitting diode is through the two ends electric current and luminous.
When coil opens circuit with the voltage supplied deficiency, there is not electric current to flow through in the coil, then light-emitting diode does not work; Because case is transparent, just can see lumination of light emitting diode from the outside, therefore can know that electromagnetic relay has fault; Cisco unity malfunction, thus confirm the reason of fault easily.
Description of drawings
Fig. 1 is the exploded view of the utility model embodiment;
Fig. 2 is the utility model embodiment coil lead pin and the sketch map that is connected of diode;
Fig. 3 is the enlarged diagram that the utility model embodiment coil lead pin is connected with diode.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the transparent mode electromagnetic relay is made up of transparent case 1 and main body 2.
The terminal pin 3 of above-mentioned coil 6 links to each other with a pin 41 of light-emitting diode 4, and light-emitting diode 4 another pins link to each other with another terminal pin 7 of coil 6 again, see Fig. 2.
The terminal pin 3 of above-mentioned coil also has breach 31, makes things convenient for a pin 41 of light-emitting diode 4 to insert wherein like this, improves efficiency of assembling, sees Fig. 2, Fig. 3.
When relay work and since in coil two ends parallel connections by light-emitting diode, therefore do not have fault when coil, during the electromagnetic relay operate as normal, light-emitting diode is through the two ends electric current and luminous.
When coil opens circuit with the voltage supplied deficiency, there is not electric current to flow through in the coil, then light-emitting diode does not work; Because case is transparent, just can see lumination of light emitting diode from the outside, therefore can know that electromagnetic relay has fault; Cisco unity malfunction, the operator can find that just electromagnetic relay damages.
Claims (2)
1. the transparent mode electromagnetic relay comprises that electromagnetic system and contact system reach the pedestal and the case of fixing these electromagnetic systems and contact system, and electromagnetic system comprises coil again, it is characterized in that: light-emitting diode and coils from parallel connection of coils, described case are transparent casing.
2. transparent mode electromagnetic relay according to claim 1 is characterized in that: the pin of described coil is provided with the fixedly breach of light-emitting diode one pin.
