Description

Technical Field

[0001] The present invention relates to the technical field of magnetic latching relays, and particularly to an installation structure of a magnetic latching relay applied to an electric energy meter. Background Art

[0002] In the prior art, when a relay is installed on an electric energy meter, the relay is independently installed at one end of the electric energy meter. Both the relay and the electric energy meter are independent individuals, resulting in a large occupied space of the installation structure and being unfavorable for assembly. Summary of the Invention

[0003] The main purpose of the present invention is to provide an installation structure of a magnetic latching relay applied to an electric energy meter, which has the characteristics of good structural compactness and convenient installation.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] An installation structure of a magnetic latching relay applied to an electric energy meter, comprising:

[0006] An electric energy meter bottom box provided with an installation groove group;

[0007] A push block slidably arranged in the electric energy meter bottom box and at one end of the installation groove group. A clamping groove is arranged on the push block, and a push piece extending into the installation groove group is convexly arranged on one side of the push block;

[0008] A magnetic circuit component fixed on the electric energy meter bottom box, and an armature component slidably arranged on the electric energy meter bottom box, connected to the clamping groove at both ends, and arranged on one side of the magnetic circuit component. A permanent magnet is arranged in the armature component;

[0009] A moving piece component arranged on the installation groove group, with one side surface directly opposite to the push piece and capable of being pushed by the push piece;

[0010] A static piece component arranged in the installation groove group;

[0011] A spring piece arranged in the installation groove group and continuously applying elastic force to make the moving piece component abut against the static piece component;

[0012] An installation copper column fixed on the terminal box and connected to the moving piece component and the static piece component.

[0013] Preferably, each moving piece component includes: a first moving connection piece connected to the installation copper column, a second moving connection piece in a U shape and with the outer side of one side arm directly opposite to the push piece, a moving piece connecting the first moving connection piece and the second moving connection piece, and a moving contact arranged on the inner side wall of the other side arm of the second moving connection piece.

[0014] Preferably, each of the first movable connection pieces includes: an L-shaped first connection piece connected to the movable piece, and a first fixing piece protruding from one end of the first connection piece and arranged in a straight line direction with the movable piece.

[0015] Preferably, each of the static piece assemblies includes: a static piece facing the movable piece assembly, a static contact arranged on the side of the static piece facing the movable piece assembly, and a second fixing piece protruding from the other end of the static piece. One end of the second fixing piece connected to the static piece is recessed to form a first groove structure, and a through hole is formed in the first groove structure.

[0016] Preferably, each of the elastic pieces is in a V shape or a U shape.

[0017] Preferably, the limiting elastic structure includes: a limiting block fixed on the electric energy meter box, and a second elastic piece arranged on the limiting block.

[0018] Preferably, the second elastic pieces are all in a V shape or a U shape.

[0019] Preferably, the mounting copper post includes a square mounting bottom plate, and a mounting fixing part integrally formed with the mounting bottom plate, having a length shorter than the mounting bottom plate and provided with a mounting hole.

[0020] Preferably, the mounting groove group includes several groups of mounting grooves. Each group of mounting grooves includes: a U-shaped engaging groove with different lengths of engaging arms, and a second mounting groove formed between the shorter engaging arm and a reverse L-shaped engaging plate. The open end of the longer engaging arm is flush with the engaging plate.

[0021] Preferably, the magnetic latching relay mounting structure further includes: a limiting elastic structure arranged on the bottom box of the electric energy meter, abuting against the outer arm of the pushing block and arranged on the other side of the magnetic circuit assembly.

[0022] Compared with the prior art, for the magnetic latching relay mounting structure applied to the electric energy meter in the present invention, when powered on, the magnetic circuit assembly generates a magnetic field, generating an attractive force on the armature assembly. The armature assembly drives the pushing block to move towards one end in the direction of the magnetic circuit assembly. At this time, the pushing piece drives the movable piece assembly to move, and the movable piece assembly disconnects from the static piece assembly. At this time, the function of the permanent magnet makes the movable piece assembly and the static piece assembly remain in a disconnected state. When a reverse current is applied, the armature assembly drives the pushing block to move in the opposite direction, and the power assembly abuts against the static piece assembly. At this time, the elastic piece continuously applies an elastic force to keep the movable piece assembly and the static piece assembly in an abutting state, enabling the present invention to effectively reduce costs during use. In addition, the structural arrangement of the present invention assembles the electric energy meter and the magnetic latching relay into an individual, with characteristics such as a compact structure, small occupied space, and convenient installation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0035] Please refer to Figure 1 , the magnetic holding relay installation structure applied to the electric energy meter in this embodiment includes: an electric energy meter bottom box 1, a push block 2 arranged in the electric energy meter bottom box 1, a magnetic circuit assembly 3 arranged in the push block 2, an armature assembly 4 arranged in the push block 2 and on one side of the magnetic circuit assembly 3, a moving piece assembly 5 arranged on the electric energy meter bottom box 1 and beside the push block 2 and pushed by the push block 2, and a static piece assembly 6 arranged on the electric energy meter bottom box 1 and beside the moving piece assembly 5 and in contact with the moving piece assembly 5, a spring piece 7 arranged on the electric energy meter bottom box 1 and on the other side of the static piece assembly 6 and in contact with the moving piece assembly 5, and an installation copper column 8 fixed on the terminal box and connected to the moving piece assembly 5 and the static piece assembly 6.

[0036] In some embodiments, installation groove groups 11 are provided on the electric energy meter bottom box 1. Specifically, the installation groove groups 11 include several groups of installation grooves, and each group of installation grooves includes: a U-shaped engaging groove with different lengths of engaging arms, and a second installation groove formed between the shorter engaging arm and the engaging plate in an inverted L shape, and the open end of the longer engaging arm is flush with the engaging plate. More specifically, the spring piece 7 is arranged in the U-shaped engaging groove, the static piece assembly 6 is arranged in the second installation groove, and the moving piece assembly 5 passes through the engaging plate and partially inserts into the second installation groove to be in contact with the static piece assembly 6. More specifically, engaging fixing columns for engaging with the push block 2 are provided on the electric energy meter bottom box 1. In some embodiments, a slide rail is provided at the position on the electric energy meter bottom box 1 where the push block 2 is installed.

[0037] Please also refer to Figure 2, in some embodiments, the pushing block 2 has a square frame structure. Oppositely arranged engaging grooves 21 are formed on the inner opposite side walls of the pushing block 2. On the side of the pushing block 2 opposite to the moving blade assembly 5 and the static blade assembly 6, a pushing piece 22 extending into the mounting groove group 11 is convexly provided. Both ends of the armature assembly 4 are respectively arranged on the engaging grooves 21. Specifically, an engaging through groove is formed on the pushing block 2, and the engaging through groove is used in cooperation with the engaging fixing column of the electricity meter bottom box 1. The diameter of the engaging fixing column is smaller than the length of the engaging through groove. In some embodiments, a sliding groove matching the slide rail can also be provided at the bottom of the pushing block 2.

[0038] In some embodiments, the magnetic circuit assembly 3 includes: a yoke fixed in the pushing block 2, arranged beside the armature assembly 4, and having both ends respectively close to the inner side walls of the pushing block 2, and a coil structure arranged in the middle of the yoke. Specifically, when the moving blade assembly 5 abuts against the static blade assembly 6 and the magnetic circuit assembly 3 is energized, the magnetic circuit assembly 3 generates a magnetic field, and then generates an attraction force on the armature assembly 4, causing the armature assembly 4 to drive the pushing block 2 to move from the armature assembly 4 towards the magnetic circuit assembly 3 direction, and the moving blade assembly 5 and the static blade assembly 6 are separated and in a disconnected state. At this time, the magnetic effect of the permanent magnet in the armature assembly 4 causes the moving blade assembly 5 and the static blade assembly 6 to remain in the disconnected state; at this time, when another direction of current is applied to the magnetic circuit assembly 3, the elastic piece 7 pushes the moving blade assembly 5 and the static blade assembly 6 to be connected, and at the same time pushes the pushing block 2 to move in the other reverse direction. At this time, the elastic force of the elastic piece 7 causes the moving blade assembly 5 and the static blade assembly 6 to remain in an abutting state. It should be noted that the current can be a forward current or a reverse current.

[0039] In some embodiments, the armature assembly 4 is slidably arranged on the electricity meter bottom box 1, with both ends connected to the engaging grooves 21 and arranged on one side of the magnetic circuit assembly 3. Specifically, the armature assembly 4 is in a U shape, and both side walls are arranged in the engaging grooves 21.

[0040] Please also combine Figure 3, in some embodiments, the moving piece assembly 5 is disposed on the mounting groove group 11, and one side surface of the moving piece assembly 5 faces the pushing piece 22 directly and can be pushed by the pushing piece 22. Specifically, each moving piece assembly 5 includes: a first moving connection piece 51 connected to the mounting copper column 8, a second moving connection piece 52 in a U shape and with the outer side of one side arm facing the pushing piece 22 directly, a moving piece 53 connecting the first moving connection piece 51 and the second moving connection piece 52, and a moving contact 54 disposed on the inner side wall of the other side arm of the second moving connection piece 52. Each first moving connection piece 51 includes: a first connection piece a1 in an L shape connected to the moving piece 53, and a first fixing piece a2 protruding from one end of the first connection piece a1 and arranged in a straight line direction with the moving piece 53. Wherein, the mounting copper column 8 is disposed on the first fixing piece a2 and one end of it is clamped on the first connection piece a1. The moving piece 53 and a part of the second moving connection piece 52 are disposed on the side of the clamping plate facing away from the second mounting groove. One end of the second moving connection piece 52 where the moving contact 54 is disposed is closely attached to one end of the clamping plate and inserted into the second mounting groove across the clamping plate. Further, the second moving connection piece 52 is disposed on the side of the clamping plate facing away from the second mounting groove and abuts against the pushing piece 22. When the pushing block 2 moves, the pushing piece 22 pushes the second moving connection piece 52, thereby driving the connection between the moving contact 54 and the static piece assembly 6.

[0041] Please also refer to Figure 4 , in some embodiments, a static piece assembly 6 opposite to the moving piece assembly 5 is disposed in the second mounting groove. Specifically, each static piece assembly 6 includes: a static piece 61 opposite to the moving piece assembly 5, a static contact 62 disposed on the side surface of the static piece 61 facing the moving piece assembly 5 directly, and a second fixing piece 63 protruding from the other end of the static piece 61. One end of the second fixing piece 63 connected to the static piece 61 is recessed to form a first groove structure b1, and a through hole b2 is opened on the first groove structure b1. Specifically, the first groove structure b1 is attached to the meter base 1, and the static piece assembly 6 is disposed on the meter base 1 through screws and the through hole. One surface of the static piece 61 abuts against the surface of the clamping plate facing the first groove.

[0042] In some embodiments, a spring piece 7 abutting against the moving piece assembly 5 is disposed on the mounting groove group 11. Specifically, please also refer to 1 and Figure 5, each of the elastic pieces 7 is disposed in the first groove and abuts against one side surface of the movable piece assembly 5, and each of the elastic pieces 7 is U-shaped. More specifically, when the movable piece assembly 5 is pushed by the pushing piece 22, the elastic piece 7 is pushed, so that the elastic piece 7 is in a compressed state. When an electric current in the other direction is applied, the elastic piece 7 elastically recovers, and due to the elastic force, the movable piece assembly 5 is in contact connection with the contact of the static piece assembly 6. It should be noted that the elastic piece 7 can also be set to be V-shaped.

[0043] Please also refer to Figure 6 , the mounting copper column 8 includes a square mounting base plate 81, and a mounting fixing portion 82 that is integrally formed with the mounting base plate 81, has a length shorter than that of the mounting base plate 81, and is provided with a mounting hole. Specifically, please also refer to Figure 1 , the mounting copper column 8 is disposed on the terminal box, and the other end of the mounting copper column 8 is connected to the movable piece assembly 5 or the static piece assembly 6.

[0044] It should be noted that in some embodiments, a limiting elastic structure can also be provided on the bottom box 1 of the electric energy meter: a limiting elastic structure that abuts against the outer arm of the pushing block 2 and is disposed on the other side of the magnetic circuit assembly 3. The limiting elastic structure includes: a limiting block fixed on the bottom box 1 of the electric energy meter, and a second elastic piece disposed between the limiting block and the pushing block 2. The second elastic piece is set to be U-shaped. Of course, the second elastic piece can also be set to be V-shaped.
