Abstract
The utility model discloses an electromagnetic relay which comprises a relay casing, the inside of which is provided with a load control relay and a lock control relay. The load control relay is provided with an armature I. The bottom of the inside of the relay casing is provided with a circuit board and a contact status feedback switch. One end of the armature I is connected with the contact status feedback switch. The circuit board is connected with the contact status feedback switch. The circuit board is provided with an inserting opening at the casing. The inserting opening comprises a wiring pole II and the wiring pole III. When a contact is switched off or switched on, one electric signal is produced, which can be transported to a control system through a lead to ensure whether the relay can work normally or not, so as to realize the feedback function. The assembled circuit arrangement ensures that the signal lines of the relay are linked by the uniform inserting openings, which is convenient and prompt, links firm and can avoid the joint from being oxygenated caused by the electromagnetic reaction.
Description
Technical field
The utility model relates to a kind of electromagnetic relay.
Background technology
Have a wide range of applications at the automation field relay, it can realize power management and other function of terminal by control signal.Without any feedback device, can not provide the combined floodgate of contact to open a sluice gate state information after the existing electromagnetic relay work, therefore when relay goes wrong, can not in time feed back to control system.And the wiring of existing electromagnetic relay holding wire is to carry out in the mode of screw lead, and such mode of connection speed is slow, connects unstablely, and is subjected to electrothermal reaction easily and oxidation at interface.
The utility model content
The technical problems to be solved in the utility model provides a kind of electromagnetic relay, and the state information of contact can be provided constantly.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: electromagnetic relay comprises the relay casing, described relay casing inside is provided with load control relay and locking control relay, described load control relay is provided with armature I, described relay casing inner bottom also is provided with circuit board and contacts status feedback switch, the end of described armature I is connected with the contacts status feedback switch, described circuit board links to each other with the contacts status feedback switch, described circuit board is provided with interface on casing, described interface comprises binding post II and binding post III.
As a kind of improvement of the present utility model, described load control relay all links to each other with circuit board with described locking control relay, and described interface also comprises binding post I, binding post IV, binding post V.
As another kind of improvement the of the present utility model, described relay bottom of shell is provided with perforate, and the circuit board that is arranged on relay casing inner bottom is led in described perforate.
The utility model adopts technique scheme: producing a signal of telecommunication when opening a sluice gate to close a floodgate in the contact, whether to determine relay working properly, realize feedback function if can flow to control system by lead; Integrated circuit arrangement connects the holding wire of relay with unified interface, fast convenient, is connected firmly, and can avoids interface to be subjected to electrothermal reaction and oxidation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done further and to be specified.
Fig. 1 is a kind of working state schematic representation of a kind of electromagnetic relay of the utility model;
Fig. 2 is the another kind of working state schematic representation of a kind of electromagnetic relay of the utility model;
Fig. 3 is the front view of a kind of electromagnetic relay of the utility model;

Embodiment
As shown in Figure 1, electromagnetic relay comprises relay casing 1, be provided with load control relay 2 and locking control relay 3 in relay casing 1 inside, load control relay 2 is provided with armature I4, locking control relay 3 is provided with armature II14, also be provided with circuit board 5 and contacts status feedback switch 6 in relay casing 1 inner bottom, the end of armature I4 is connected with contacts status feedback switch 6, circuit board 5 and contacts status feedback switch 6, load control relay 2 links to each other with locking control relay 3, as shown in Figure 3, on casing, be provided with the interface 7 of rectangle at circuit board 5, in interface 7, be provided with binding post I8, binding post II9, binding post III10, binding post IV11, binding post V12.Binding post II9 and binding post III10 are communicated with contacts status feedback switch 6, and binding post I8, binding post IV11 and binding post V12 are communicated with load control relay 2 and locking control relay 3 respectively, like this as long as just can be on electromagnetic relay with signal wire connecting with a socket corresponding with interface 7, no longer need to install by screw, thereby the holding wire that makes the ground electromagnetic relay is easy to connect fast, the insulation characterisitic of interface 7 makes interface avoid being subjected to electrothermal reaction and oxidation, prolongs the useful life of interface.
Control signal is by binding post I8, binding post IV11 and binding post V12 enter electromagnetic relay, as shown in Figure 2, armature I4 and armature II14 action back state change, make contacts status change, this moment, armature I4 promoted contacts status feedback switch 6, and then produced a pulse signal on the line, signal feeds back to control system through binding post II9 and binding post III10 output by holding wire, and control system just can be judged the state of contact by pulse signal.When control signal is passed through binding post I8 again, binding post IV11 and binding post V12 enter electromagnetic relay, return to original state after making armature I4 and armature II14 action, as shown in Figure 1, contacts status feedback switch 6 is not subjected to armature I4 to promote the state that recovers original at this moment, produces a pulse signal simultaneously on the line.Electromagnetic relay feeds back to control system constantly with contacts status under the effect of contacts status feedback switch 6 thus, just can determine whether relay is working properly.
As shown in Figure 4, relay casing 1 bottom is provided with perforate 13, the circuit board 5 that is arranged on relay casing 1 inner bottom is led in perforate 13, the copper sheet corresponding alignment apertures 13 just on the circuit board 5 with binding post I8, binding post II9, binding post III10, binding post IV11, binding post V12, therefore holding wire can also be connected perforate 13 places, and the utility model electromagnetic relay can also be Embedded mounting means like this.
