Background

An electromagnetic relay is an electronic control device having a control system (also called an input loop) and a controlled system (also called an output loop), which is generally applied to an automatic control circuit, and is actually an "automatic switch" that uses a small current to control a large current. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like.

The existing electromagnetic relay generally only adopts one coil to carry out suction and release control.

Detailed Description

The following description of a preferred embodiment of the present invention will be made in conjunction with the accompanying drawings.

Referring to fig. 1, it is a relay controlled by two electromagnetic loops, the contacts including two sets of series connection are the first contact group 1 and the second contact group 2, and two sets of contact driving mechanisms, namely the first coil driving mechanism 3 for controlling the opening and closing of the first contact group, and the second coil driving mechanism 4 for controlling the opening and closing of the second contact group. Namely the utility model discloses set up two sets of contact groups of series connection and the solitary control coil actuating mechanism that corresponds for when a coil drive mechanism's coil pack broke down, another coil drive mechanism's coil pack can also normally work, thereby avoids breaking down because of a coil drive mechanism of coil pack, and the product that leads to completely became invalid, makes the use of whole equipment go wrong.

The first contact group comprises two pairs of first moving contacts a11 and first fixed contacts a21, and first moving contacts B12 and first fixed contacts B22. The second contact group comprises two groups of oppositely arranged second moving contacts A13 and second fixed contacts A23, and second moving contacts B14 and second fixed contacts B24. In this embodiment, the first moving contact a11 and the first moving contact B12 are respectively disposed at two ends of the first moving contact piece 100, and form an integral conducting structure. The second moving contact a13 and the second moving contact B14 are respectively disposed at two ends of the second moving contact piece 200, and form an integral conducting structure. The first fixed contact B22 and the second fixed contact a23 are disposed on the same conductive terminal 300 to form an integral conducting structure.

In order to make the structural layout reasonable and reduce the relay activity, the first coil driving mechanism 3 is disposed outside (i.e., above in fig. 1 and 2) a side of the first movable contact piece 100 away from the first fixed contact a21 and the first fixed contact B22, and the second coil driving mechanism 4 is disposed outside (i.e., above in fig. 1 and 2) a side of the second movable contact piece 200 away from the second fixed contact a23 and the second fixed contact B24.

In order to reduce the processing cost, the first coil driving mechanism and the second coil driving mechanism have the same structure, and respectively comprise a driving bracket 341, a coil assembly 342 fixed on the driving bracket 341, an armature 343 with one end arranged outside one end surface of the coil assembly and the other end in an L shape, and a connecting piece 344 for connecting the other end of the armature with a movable contact piece to be driven; the middle portion of the armature 343 is rotatably connected to the driving bracket 341, and a return spring 345 for moving one end of the armature 343 away from the coil assembly 342 is provided between the middle portion of the armature 343 and the connection member 344.

Preferably, the two sides of the middle portion of the armature 343 are respectively provided with a clamping groove 3431, and the driving bracket 341 is correspondingly provided with a clamping point clamped in the clamping groove to form a rotation fulcrum. Two side edges of the other end of the armature 343 are respectively provided with a notch so that the middle part thereof forms an L-shaped bent part 3432, and spring clamping grooves 3433 for assembling return springs are respectively arranged at the positions of the notches of the armature.

It should be noted that the first coil driving mechanism and the second coil driving mechanism may have different structures or other structures having relative functions to achieve the functions of the present invention, and the present invention is not particularly limited.

The utility model discloses a concrete theory of operation as follows:

in operation, the coil assembly 342 is energized to generate an attractive force on one end of the armature 343, so that the armature 343 rotates around a rotation connection point, i.e., a rotation fulcrum, of the armature 343 and the driving bracket 341, and the other end of the armature 343 and the connecting piece 344 connected thereto are away from the coil assembly 342, thereby driving the first movable contact 100 or the second movable contact 200 connected to the connecting piece 344 to close and conduct a corresponding set of contacts (i.e., the first contact set or the second contact set), respectively. On the contrary, when the coil assembly is powered off, the attraction force of the coil assembly 342 to the armature 343 disappears, and due to the action of the return spring 345, one end of the armature 343 is separated from the coil assembly, and meanwhile, the other end of the armature drives the connecting piece 344 and the corresponding first movable contact piece or second movable contact piece to move, so that the corresponding first contact set or second contact set is separated and disconnected.

The first coil driving mechanism controls the first contact group independently, the second coil blocking mechanism controls the second contact group independently, namely the two contact groups are controlled by the corresponding coil driving mechanisms independently, and therefore when the electric vehicle works, the two coil driving mechanisms can work simultaneously or work independently. And meanwhile, when the device works, the corresponding contact set does not work and the operation of the whole device is influenced due to the fact that one coil assembly breaks down.

Therefore, the utility model discloses a set up two sets of contact group that can use alone or simultaneously and the coil actuating mechanism who corresponds respectively, avoid the whole product function failure that a coil trouble leads to reduce the possibility that the product became invalid completely to a certain extent, promoted the security of product.
