Description

Technical Field

[0001] The present invention belongs to the technical field of magnetic latching relay accessories, and particularly relates to a pusher for a magnetic latching relay. Background Art

[0002] A magnetic latching relay is a control component that, under the action of a drive control signal, uses the interaction and relative movement of an electromagnetic coil and a permanent magnet to close and disconnect a circuit, and can still maintain the circuit in an on or off state after the drive control signal disappears. It has the characteristics of energy saving and stable operation, and is widely used in power system protection devices and various remote control, telecontrol, and communication devices. It is particularly widely used in smart electricity meters as the main component of smart electricity meters. The working state of the coil assembly of the magnetic latching relay is transmitted to the output circuit through a pusher.

[0003] Existing pushers are generally of a strip-shaped structure, injection-molded from engineering plastics, and are provided with a plurality of openings. One of the openings is used to assemble the lever on the relay armature assembly, and a plurality of the openings are used to assemble the ends of the moving reed of the relay output circuit.

[0004] During the injection molding process of engineering plastics, internal stress will be generated due to uneven cooling. This internal stress easily causes the plastic parts to deform, bend, or even break, thereby causing the relay to fail. To reduce the internal stress generated during the injection molding process of the pusher, a plurality of process holes or grooves are provided on the strip-shaped pusher.

[0005] Existing process grooves on both sides will cause the surface of the pusher to be uneven, increase friction, and reduce the strength of the pusher. Summary of the Invention

[0006] The purpose of the present invention is to provide a pusher for a magnetic latching relay with a reasonable structure and strong applicability.

[0007] The technical solution for achieving the purpose of the present invention is a pusher for a magnetic latching relay, including a pusher body of a flat structure. On the top edge of the pusher, there is provided a swing rod protrusion and two spring piece protrusions. The two spring piece protrusions are symmetrically arranged on both sides of the swing rod protrusion. Inside the swing rod protrusion, there is a swing rod card slot with an opening on the top surface and one side surface. Inside the spring piece protrusion, there is a spring piece card slot with an opening on the top surface and one side surface. On the bottom surface of the pusher body, there are three grooves with openings on the bottom surface. The grooves are respectively directly below the swing rod card slot and the spring piece card slot. At the bottom of the pusher body, an n-shaped limiting groove is fixed. Inside the pusher body, there is a process groove. The opening of the process groove is provided on the top surface and / or the bottom surface of the pusher body. The distance from the process groove to the symmetric side surfaces of the pusher body is the same. At least one reinforcing rib is provided in the process groove.

[0008] The opening of the process groove is located on the top surface of the pushing piece body and the bottom edge of the process groove is closed.

[0009] Or the opening of the process groove is located on the bottom surface of the pushing piece body and the top edge of the process groove is closed.

[0010] Or the opening of the process groove is located on both the top surface and the bottom surface of the pushing piece body, and a sealing strip is transversely fixed in the middle of the pushing piece.

[0011] Further, the heights of the swing rod protrusion and the spring piece protrusion are the same and are 1 / 2 of the height of the pushing piece body.

[0012] Further, the depth of the n-shaped limiting groove is 1 / 3 of the height of the pushing piece body.

[0013] The present invention has positive effects: The structure of the present invention is reasonably arranged. It is provided with a process groove, and the opening of the process groove is on the top surface or / and the bottom surface. Thus, during the injection molding process, it is beneficial to ensure uniform cooling, thereby reducing internal stress. It can ensure that the thicknesses of both sides of the pushing piece are the same, and at the same time, it can also make the side surface smoother, which is beneficial to reducing friction during use. And at least one reinforcing rib is added, which is beneficial to ensuring the overall mechanical strength, improving the stability and reliability of use, and has strong applicability and good practicability.
