Technical Field

[0001] The present application relates to the technical field of magnetic latching relays, and in particular to a bidirectional magnetic latching relay. Background Art

[0002] A magnetic latching relay is a structure used to control circuits. It can maintain the state of a circuit without continuous power supply, allowing the relay to maintain the circuit state for a long time. Magnetic latching relays are used in fields such as high-current smart prepaid meters. In the past, two relays were connected to the meter to achieve control of the circuit.

[0003] In the related art, the relay includes a housing, a driving member is arranged in the housing, a moving plate is arranged on the driving member, a static plate and a moving plate are arranged in the housing, and the driving member drives the static plate to abut against the moving plate or to separate from the moving plate through the moving plate.

[0004] Since the high-current smart prepaid meter requires two relays to be connected to the meter to achieve circuit control, and the two relays cannot control the consistency of their parameters well, there is a certain uncertainty in the subsequent debugging of the meter. Utility Model Content

[0005] In order to improve the problem that it is difficult to control parameter consistency between two relays, the present application provides a bidirectional magnetic latching relay.

[0006] The present application provides a bidirectional magnetic latching relay, which adopts the following technical solution:

[0007] A bidirectional magnetic latching relay comprises a shell, a driving member is provided on the shell, two static plates and two moving plates are provided in the shell, a moving plate is provided on the driving member, two pushing grooves are provided on the moving plate, the static plates are located in the pushing grooves, and the driving member drives the moving plates to move via the moving plates.

[0008] By adopting the above technical solution, the movable plate is located in the pushing groove, so that when the driving member drives the movable plate to move, the groove wall of the pushing groove can drive the movable plate to move, so that the movable plate and the static plate can be separated or the movable plate abuts against the static plate to achieve the connection or disconnection of the circuit, so that the relay can control the parameters of two different circuits, and the parameters in the two circuits are consistent, which is convenient for the subsequent debugging of the electric meter.

[0009] Optionally, the movable plate is provided with a receiving groove, the receiving groove extends along the thickness direction of the shell, and the shell is provided with a baffle, and the baffle is located in the receiving groove.

In addition, a baffle is provided on the shell, and the baffle is located in the receiving groove, so that the baffle can block the arc generated when the static plate and the moving plate are separated, so that the arc is not easy to move to the driving part through the movable plate, thereby reducing the damage of the arc to the driving part.

[0012] By adopting the above technical solution, the static piece is inserted into the through hole from one side of the opening of the placement groove, and the locking block is located in the locking groove, so that the static piece is fixed in the shell. The locking plate is driven to move by the elastic member, so that the locking plate blocks the opening of the accommodating hole, making it difficult for the locking block to escape from the locking groove through the accommodating hole, so that the groove wall of the locking groove restricts the locking block, so that the locking block can be fixed in the shell. If the static piece needs to be replaced, people can move the locking plate and directly take the static piece out of the through hole, so that people do not need to completely unlock the shell to take out the static piece, which is convenient for people to replace the static piece.

[0019] Optionally, an end surface of the stop block is provided with an inclined surface, the inclined surface is inclined in a direction from the stop hole to the elastic groove and away from the stop spring, and the inclined surface is located on the moving path of the locking plate.

[0020] By adopting the above technical solution, the inclined surface is located on the moving path of the locking plate, so that the locking plate can move the stop block along the inclined surface toward the stop spring when moving, which makes it easier for the stop block to disengage from the stop groove, so that people do not need to manually drive the stop block to disengage from the stop groove, thereby making it easier for people to slide the locking plate.

[0021] Optionally, a groove is provided on the locking plate, and when the stop block is inserted into the groove, the locking plate is not located in the accommodating hole.

[0022] By adopting the above technical solution, the stop block is inserted into the groove, so that the groove wall of the groove restricts the stop block, and the locking plate and the stop block are fixed to each other, so that the locking plate is not located in the accommodating hole, so that people do not need to pull the locking plate to remove the static plate from the perforation, which makes it easy for people to remove the static plate.
