[0033] See Figure 1 The utility model discloses a relay that is easy to disassemble and assemble, including an armature assembly 1, a push piece 2, and a dynamic spring assembly 3. The first end of the push piece 2 is connected to the armature assembly 1, and the second end of the push piece 2 is connected to the dynamic spring assembly 3. When the armature assembly 1 rotates around the Z axis, the push piece 2 is driven to move in the X axis direction.

[0034] See Figure 7 and Figure 8As can be understood, as a specific example scheme of applying the relay with the above structure, the relay further comprises the base 4, the bobbin 5, the core 6, the coil 7, the yoke 8, and the static spring piece 9, wherein the bobbin 5 is arranged on the base 4, the core 6 penetrates through the bobbin 5, the coil 7 is arranged on the circumferential outer side of the core 6, the two yokes 8 are respectively connected to the two ends of the core 6, the armature assembly 1 is arranged on the base 4 in the Z-axis direction and is located between the two yokes 8, the static spring piece 9 and the moving spring assembly 3 are arranged on the base 4 in the X-axis direction and the moving spring assembly 3 is located between the static spring piece 9 and the bobbin 5. When the coil 7 is connected with the forward or reverse excitation current, the armature assembly 1 rotates in the Z-axis direction and drives the push piece 2 to move in the X-axis direction, and the push piece 2 drives the moving spring assembly 3 to make the moving spring assembly 3 communicate or disconnect with the static spring piece 9.

[0035] In the embodiment, referring to Figure 1 , Figure 3 and Figure 5 , the first end of the push piece 2 is provided with a clamping groove 21, a first stop block 22, a second stop block 23, and a step structure 24. The clamping groove 21 is arranged through in the Y-axis direction and is substantially in the shape of a cuboid through groove. The first stop block 22 and the second stop block 23 are located on the two sides of the clamping groove 21 in the Z-axis direction, that is, the second stop block 23, the clamping groove 21, and the first stop block 22 are arranged in the Z-axis direction in sequence. The first stop block 22 and the second stop block 23 are used to limit the Z-axis direction in cooperation with the armature assembly 1. Specifically, the first stop block 22 extends and protrudes on one side of the push piece 2 in the Y-axis direction, and the second stop block 23 extends and protrudes on the other side of the push piece 2 in the Y-axis direction. Referring to the orientation shown in Figure 3 , the first stop block 22 extends and protrudes toward the upper surface of the push piece 2, and the second stop block 23 extends and protrudes toward the lower surface of the push piece 2. The step structure 24 is arranged in a recessed manner and is located on one side of the clamping groove 21, specifically, the step structure 24 is close to the first stop block 22. The second end of the push piece 2 is provided with a T-shaped head structure, which is used to connect with the moving spring assembly 3. The T-shaped head structure comprises a horizontal section 25 and a vertical section 26. One end of the horizontal section 25 is fixedly connected to the main body end of the push piece 2, and the other end of the horizontal section 25 is fixedly connected to the middle of the vertical section 26. Specifically, the horizontal section 25 is arranged in the X-axis direction, and the vertical section 26 is arranged in the Z-axis direction.

[0036] In the embodiment, referring to Figure 1 , Figure 2 and Figure 5The armature assembly 1 has a push head 132, a first limit block 133, and a second limit block 134. The push head 132 is used to be rotatably installed on the slot 21. When the armature assembly 1 rotates around the Z-axis, the push head 132 swings and rotates in the slot 21. The push head 132 pushes the slot 21 to drive the push piece 2 to move in the X-axis direction. It can be seen that the axis direction of the relative rotation of the push head 132 in the slot 21 is also along the Z-axis direction; in the Y-axis direction, the first limit block 133 and the second limit block 134 are respectively arranged on both sides of the rotation center of the push head 132. As a specific example, the armature assembly 1 includes a magnetic armature piece 11, a permanent magnet 12 and a plastic part 13. The magnetic armature piece 11 and the permanent magnet 12 are arranged on the plastic part 13. A connecting block 131 is also protruding from the plastic part 13. The push head 132 is fixed to the connecting block 131, the first limit block 133 is fixed to the push head 132, and the second limit block 134 is fixed to the connecting block 131; of course, in other examples, according to the size and shape of the push head 132, the second limit block 134 can also be fixed to the push head 132.

[0037] In this embodiment, preferably, based on the characteristics of the aforementioned slot 21, push head 132, first limit block 133, and second limit block 134, the first limit block 133 passes through the slot 21 obliquely during assembly, and after being straightened, the push head 132 is rotatably installed on the slot 21 and forms a limit in the X-axis direction, and the first limit block 133 and the second limit block 134 are respectively located on opposite sides of the Y-axis direction of the slot 21 and form a limit in the Y-axis direction; in addition, after the push piece 2 and the armature assembly 1 are assembled, the connection between the push piece 2 and the armature assembly 1 can also form a limit in the Z-axis direction. Specifically, preferably, the first stop block 22 corresponds to the first limit block 133, and the second stop block 23 corresponds to the second limit block 134. The first stop block 22 blocks the outside of the first limit block 133 in the Z-axis direction, and the second stop block 23 blocks the outside of the second limit block 134 in the Z-axis direction, thereby forming a limit in the Z-axis direction.

[0038] In the above scheme, the two limit blocks are respectively arranged on both sides of the rotation center of the push head 132. During assembly, they are tilted at a certain angle so that the first limit block 133 passes through the slot 21 and the push head 132 is installed in the slot 21. After being straightened and reset, the push head 132 and the slot 21 form a limit in the X-axis direction, and the two limit blocks are used to form a limit in the Y-axis direction. The two stop blocks and the two limit blocks can also be used to form a limit in the Z-axis direction. In this way, when the relay is in operation, the push head 132 swings and pushes the slot 21, so that the push piece 2 moves in the X-axis direction. The above structure can form a self-limiting function between the armature assembly 1 and the push piece 2, making the relay more stable when in operation, and convenient to disassemble and assemble, with a simple structure.

[0039] The limit in the X-axis direction is based on the cooperation between the push head 132 and the clamping groove 21. In this embodiment, referring to Figures 1 to 3 , Figure 5 and Figure 6 , specifically, the push head 132 is substantially cylindrical, the push head 132 extends along the Z-axis direction, the diameter of the push head 132 is matched with the size of the clamping groove 21 in the X-axis direction, which means that after the assembly is completed, the push head 132 is always placed in the clamping groove 21 of the push piece 2, so when the push head 132 reciprocates with the push piece 2, in addition to the small friction force, the push piece 2 will always be subjected to a horizontal pushing force perpendicular to the inner wall of the clamping groove 21, which is always consistent with the direction of the movement of the push piece 2, thereby ensuring the stability of the movement of the push piece 2 in the X-axis direction, thereby improving the electrical performance index of the product; the length L1 of the push head 132 is less than the size L3 of the clamping groove 21 in the Z-axis direction, which means that the push head 132 is less convenient when being tilted into the clamping groove 21, and is not easy to interfere.

[0040] The limit in the Y-axis direction is based on the cooperation between the two limiting blocks and the two opposite sides of the push piece 2 in the Y-axis direction. In this embodiment, referring to Figure 6 and Figure 6 , the first limiting block 133 is located on the upper side of the rotation center of the push head 132, and the second limiting block 134 is located on the lower side of the rotation center of the push head 132, based on the arrangement of the second limiting block 134, the push head 132, and the first limiting block 133 along the Z-axis direction in sequence, therefore, the overall size L4 of the push head 132, the first limiting block 133, and the second limiting block 134 in the Z-axis direction is greater than the size L3 of the clamping groove 21 in the Z-axis direction, so that after the assembly is completed, when the push head 132 reciprocates with the push piece 2, the movement of the push piece 2 along the Y-axis direction is limited, avoiding the push head 132 from being separated from the push piece 2, or avoiding the large swing of the push piece 2 from causing a false overstroke, thereby improving the movement stability. It can be understood that the limit in the Y-axis direction can belong to a clearance fit, thereby allowing the push head 132 to rotate in the clamping groove 21, and it can only be required to control the amount of movement along the Y-axis direction to be within a controllable small range. In addition, the orientation arrangement of the two limiting blocks can also be other schemes, for example: the two limiting blocks are arranged on one side (such as the right side) of the length direction of the push head 132 along the Z-axis direction, at this time, the two limiting blocks adopt a similar arrangement mode of clamping the push piece 2, and of course, a clearance is still required to allow the push head 132 to rotate in the clamping groove 21. In addition, preferably, the first limiting block 133 is located at the stepped structure 24, which can limit the angle range of the rotation of the push head 132 in the clamping groove 21 and control the overall thickness of the push piece 2 by using the two side walls of the stepped structure 24.

[0041] Wherein, the limit formed in the Z-axis direction is based on the cooperation of the two blocks and the two limit blocks in the Z-axis direction. It should be noted that the limit formed in the Z-axis direction can also belong to the clearance fit. It can only be required to control the amount of movement in the Z-axis direction to be within a controllable small range. The purpose is to avoid the failure of the limit in the Y-axis direction when the movement in the Z-axis direction occurs. In the embodiment, referring to Figure 6 and Figure 6 The second limit block 134, the push head 132, and the first limit block 133 are arranged in the Z-axis direction in sequence. Therefore, the second block 23, the slot 21, and the first block 22 are also arranged in the Z-axis direction in sequence. The gap size L5 of the second block 23 and the first block 22 in the Z-axis direction is slightly larger than the overall size L4 of the push head 132, the first limit block 133, and the second limit block 134 in the Z-axis direction. Therefore, no obstruction is formed in the installation process of the subsequent reset after the tilt loading. In order to facilitate assembly, the overall size L2 of the push head 132 and the first limit block 133 in the Z-axis direction is smaller than the size L3 of the slot 21 in the Z-axis direction. The control in size preferably meets: (L5-L4)<(L4-L3). Specifically, when the second block 23 abuts against the second limit block 134, the first limit block 133 still remains at the step structure 24 and cannot enter the slot 21. When the first block 22 abuts against the first limit block 133, the second limit block 134 also cannot enter the slot 21. Therefore, the failure of the limit in the Y-axis direction when the movement in the Z-axis direction occurs is avoided.

[0042] In other preferred embodiments, when other features can limit the movement of the push piece 2 in the Z-axis direction or control the amount of movement of the push piece 2 in the Z-axis direction, the two blocks can be cancelled if the limit of the two limit blocks in the Y-axis direction is not failed. For example, the overall size L2 of the push head 132 and the first limit block 133 in the Z-axis direction is greater than the size L3 of the slot 21 in the Z-axis direction. The overall size of the push head 132 and the second limit block 134 in the Z-axis direction is also greater than the size L3 of the slot 21 in the Z-axis direction. In this way, the connection between the push piece 2 and the armature assembly 1 can form a limit in the Z-axis direction. Alternatively, the connection structure of the moving spring assembly 3 and the push piece 2 can also limit the movement of the push piece 2 in the Z-axis direction or control the amount of movement of the push piece 2 in the Z-axis direction.

[0043] Referring to Figure 1 and Figure 4In this embodiment, the dynamic spring assembly 3 includes an end foot 31, a spring piece 32 and at least one dynamic spring piece 33. The dynamic spring piece 33 is provided with a dynamic contact 34, and the static spring piece 9 is provided with a static contact corresponding to the dynamic contact 34. The end foot 31 is inserted into the base 4, and the first end of the dynamic spring piece 33 is connected to the end foot 31. The second end of the dynamic spring piece 33 is provided with a groove 331. The groove 331 is embedded in the horizontal section 25 and blocks the longitudinal section 26 on one side of the second end of the dynamic spring piece 33. The first end of the spring piece 32 is connected to the dynamic spring piece 33, and the second end of the spring piece 32 is against the main end of the push piece 2. The spring piece 32 provides elastic force for the dynamic spring piece 33.

[0044] In this way, a T-shaped head structure is provided at the second end of the push piece 2, and a spring piece 32 is provided in the dynamic spring assembly 3. The T-shaped head structure is utilized to realize convenient assembly of the dynamic spring piece 33 and the spring piece 32. The spring piece 32 is also utilized to provide a pre-tightening force. When the push piece 2 moves forward, the force of the push piece 2 acts on the dynamic spring piece 33 through the elastic force of the spring piece 32, thereby providing an overtravel effect. When the push piece 2 moves backward, the push piece 2 pulls the dynamic spring piece 33 to move.

[0045] Specifically, during the operation of the push piece 2 driving the dynamic spring assembly 3 to complete the contact operation, when the dynamic and static contacts make contact, the swing of the dynamic spring 33 is prevented. The push piece 2 continues to move forward, causing the longitudinal section 26 to separate from the side of the second end of the dynamic spring 33. The push piece 2 compresses the spring 32. The elastic force of the spring 32 is applied to the dynamic spring 33, thereby providing elastic pressure to the dynamic and static contacts, achieving overtravel. Compared to the prior art method of adding a spring to the dynamic contact 34 (the dynamic contact 34 is slidably mounted on the dynamic spring 33), this solution can ensure the conductive performance of the dynamic contact 34 because the dynamic contact 34 remains fixed to the dynamic spring 33 (specifically, by riveting or welding, etc.), and has a simple structure and is easy to assemble.

[0046] See Figure 1 and Figure 4 More preferably, at least one of the movable springs 33 is further provided with a support 332. The support 332 is arranged corresponding to the groove 331 and is used to support the longitudinal section 26, thereby reducing wear and chip generation when the movable spring 33 slides relative to the T-shaped head structure of the push plate 2. The second end of the spring 32 is bent to form a hook 321. The hook 321 is used to hook the main end of the push plate 2, ensuring a stable connection between the spring 32 and the push plate 2 and preventing it from loosening. In addition, the combined action of the support 332 and the hook 321 can also provide a certain force to limit the movement of the push plate 2 in the Y-axis direction.

[0047] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
