Abstract
The utility model relates to a transparent electromagnetic relay, comprising an electromagnet system, a contact system, a base used for fixing the electromagnet system and the contact system, and a cover; wherein the electromagnet system comprises a coil; the connection in series between a resistance and a light emitting diode is connected with the both ends of the coil in parallel; and the cover is transparent. The utility model has the advantages that the connection in series between the light emitting diode and the resistance is connected with the both ends of the coil in parallel, so when the coil operates normally, the electromagnetic relay also operates normally; when the current flows through the connection in series between the light emitting diode and the resistance light, the light emitting diode lights; when the coil breaks or the power supply voltage is insufficient and no current flows through the coil, the light emitting diode does not light; and due to the transparent cover, the illumination of the light emitting diode can be detected from outside in order to acquire whether the electromagnetic relay fails or can not operate normally so as to conveniently identify the failure reason.
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 electromagnetic system and contact system and fixes the bobbin of these electromagnetic systems and contact system, base plate and case and form, electromagnetic system comprises iron core, coil, yoke, armature, and contact system comprises moving contact, normally opened contact and normally-closed contact, lead wire etc.Owing to relay causes its coil to open circuit because of frequent use or because of making reason, existing case is opaque material and makes, 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
Technical problem to be solved in the utility model 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 determining.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The transparent mode electromagnetic relay, comprise electromagnetic system and contact system and fix the pedestal and the case of these electromagnetic systems and contact system, electromagnetic system comprises coil again, it is characterized in that: be connected in parallel on described coil two ends after light-emitting diode and the resistance series connection, described case is a transparent casing.
Compared with prior art, advantage of the present utility model is:
Since in coil two end parallel connections conjuncted by light-emitting diode and resistance string, therefore working as coil does not have fault, during the electromagnetic relay operate as normal, light-emitting diode and resistance string be conjuncted passes through two end electric currents 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 determine the reason of fault easily.
Description of drawings
Fig. 1 is the exploded view of the utility model embodiment.
Fig. 2 is the connection diagram of the utility model embodiment coil lead pin and 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 another pin 42 welds with an end 51 of resistance 5, and the other end 52 of resistance 5 links to each other with another terminal pin 7 of coil 6 again, sees 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 end parallel connections conjuncted by light-emitting diode and resistance string, therefore working as coil does not have fault, during the electromagnetic relay operate as normal, light-emitting diode and resistance string be conjuncted passes through two end electric currents 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.
The operation principle of electromagnetic relay for knowing, is no longer narrated at this.
Claims (2)
1, transparent mode electromagnetic relay, comprise electromagnetic system and contact system and fix the pedestal and the case of these electromagnetic systems and contact system, electromagnetic system comprises coil again, it is characterized in that: be connected in parallel on described coil two ends after light-emitting diode and the resistance series connection, described case is a transparent casing.
2, transparent mode electromagnetic relay according to claim 1 is characterized in that: be with the fixedly breach of light-emitting diode one pin on the pin of described coil.
