[0002] Relays are divided into high-voltage and low-voltage systems. The high-voltage system includes stationary contacts, moving contacts, lower armature, lower armature frame, upper armature frame, upper armature, and contact springs, while the low-voltage system includes magnetic pole plates, stationary iron cores, push rods, moving iron cores, and return springs. A technical problem exists between the high-voltage and low-voltage systems that is prone to breakdown, primarily due to a high-low voltage breakdown between the upper armature and the magnetic pole plates, which can damage the contactor. Summary of the Invention

The lower armature frame can drive the lower armature to move toward or away from the upper armature. The lower armature frame is provided with a first limiting part. During the movement of the lower armature frame, the insulating frame contacts and cooperates with the first limiting part to limit the movement direction of the lower armature frame.

[0017] In an optional embodiment, the second limiting part is provided with a limiting insulating block, and the second limiting part contacts and cooperates with the first limiting part through the limiting insulating block.

[0018] In an optional embodiment, the second limiting portion protrudes toward the first limiting portion.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] Example 1

[0044] A relay with high and low voltage insulation structure, such as Figure 1 and Figure 2 As shown, it includes: a high-voltage system, including an upper armature 130 and an insulating frame 140, which are fixedly disposed between the upper armature 130 and the insulating frame 140; a low-voltage system, including a magnetic pole plate 210; and fixed feet 220, which are fixedly connected to the insulating frame 140 and the magnetic pole plate 210 respectively, and the fixed feet 220 are made of metal.

[0045] An insulating frame 140 is used to fix the upper armature 130, and the insulating frame 140 is used to achieve insulation between the upper armature 130 and the magnetic pole plate 210, thereby achieving insulation isolation between the high-voltage system and the low-voltage system and solving the insulation problem between the high-voltage system and the low-voltage system. The insulating frame 140 is fixedly connected to the magnetic pole plate 210 by metal fixing feet 220. The metal fixing feet 220 can achieve a higher connection strength with the magnetic pole plate 210, thereby ensuring the connection effect between the insulating frame 140 and the magnetic pole plate 210, and ensuring the firmness of the connection between the insulating frame 140 and the upper armature 130 during the use of the relay.

[0046] like Figure 1 and Figure 2 As shown, the high-voltage system includes not only the upper armature 130 and the insulating frame 140, but also the lower armature 150, the lower armature frame 160, the stationary contact 110, and the moving contact 120. The lower armature 150 is fixedly installed on the lower armature frame 160, and the moving contact 120 is fixedly installed between the lower armature 150 and the lower armature frame 160. The low-voltage system includes not only the magnetic pole plate 210, but also the stationary iron core 230, the push rod 240, and the moving iron core 250. The push rod 240 passes through the magnetic pole plate 210 and is connected to the lower armature frame 160. When the moving iron core 250 moves, the moving iron core 250 drives the lower armature frame 160 to move through the push rod 240, thereby causing the lower armature 150 to move toward or away from the upper armature 130. The lower armature frame 160 is further provided with an insulating seat, which covers the lower part of the lower armature frame 160, thereby achieving insulation isolation between the lower armature frame 160 and the magnetic pole plate 210. In other embodiments, optionally, insulation isolation between the lower armature frame 160 and the magnetic pole plate 210 can also be achieved through other structures, such as providing a corresponding insulating structure on the magnetic pole plate 210.

[0047] The insulating frame 140 includes an upper armature frame 141 and an insulating block 142, such as Figure 1 and Figure 2As shown, the upper armature frame 141 and the insulating block 142 are fixedly disposed together, the insulating block 142 is fixedly connected to the fixing foot 220, and the upper armature 130 is fixedly disposed on the upper armature frame 141. The fixing foot 220 can be fixedly connected to the insulating block 142 by means of plugging, hot riveting, bonding, or injection molding. The upper armature frame 141 can be made of metal, and the upper armature 130 can be fixed to the upper armature frame 141 by means of riveting, welding, etc. In this embodiment, the insulating block 142 can be made of insulating materials such as epoxy resin, polycarbonate, polystyrene, or alumina ceramic.

[0048] In this embodiment, as Figure 2 As shown, the fixing foot 220 is fixedly connected to the magnetic pole plate 210 by riveting. In other embodiments, optionally, the fixing foot 220 can also be fixedly connected to the magnetic pole plate 210 by welding or other fixing methods. In this embodiment, a metal fixing foot 220 is used, which facilitates fixing methods such as riveting and welding with the magnetic pole plate 210. Riveting and welding can achieve a stronger fixing effect, ensuring a stable connection between the fixing foot 220 and the magnetic pole plate 210, and achieving higher reliability during long-term use of the relay. Specifically, the fixing foot 220 can be made of metal materials such as aluminum or steel.

[0049] In this embodiment, as Figure 1 and Figure 2 As shown, the lower armature frame 160 is provided with a first limiting part 161. During the movement of the lower armature frame 160, the insulating frame 140 contacts and cooperates with the first limiting part 161 to limit the movement direction of the lower armature frame 160, thereby making the movement of the lower armature frame 160 more accurate, avoiding shaking during the movement of the lower armature frame 160, and ensuring that the relative position of the stationary contact 110 and the moving contact piece 120 is more accurate.

[0050] In this embodiment, as Figure 1 and Figure 2As shown, the lower armature frame 160 is disposed inside the upper armature frame 141. The two sides of the lower armature frame 160 are respectively disposed opposite to the two sides of the upper armature frame 141. Two legs are formed on each of the left and right sides of the lower armature frame 160. Each leg is provided with a first limiting part 161. The first limiting part 161 protrudes towards the upper armature frame 141 of the insulating frame 140. Two legs are formed on each of the left and right sides of the upper armature frame 141. Each leg is connected to an insulating block 142. Each insulating block 142 is connected to a fixing foot 220. A second limiting part 143 is provided on each leg. The second limiting part 143 protrudes towards the first limiting part 161. The second limiting part 143 cooperates with the first limiting part 161 to limit the movement. In this embodiment, the first limiting part 161 and the lower armature frame 160 are integrally formed by partially bending the lower armature frame 160; the second limiting part 143 and the upper armature frame 141 are integrally formed by partially bending the upper armature frame 141. In this embodiment, when the moving contact 120 and the stationary contact 110 are in contact and conducting, the upper armature frame 141 and the lower armature frame 160 can also conduct through the contact cooperation of the first limiting part 161 and the second limiting part 143. At this time, both the lower armature frame 160 and the lower armature frame 160 are high-voltage systems. The upper armature frame 141 achieves insulation isolation with the magnetic pole plate 210 through the insulating block 142, and the lower armature frame 160 achieves insulation isolation with the push rod 240 through the insulating seat, thereby achieving insulation isolation between the high-voltage system and the low-voltage system, and preventing breakdown of the high and low voltage systems.

[0051] In this embodiment, the relative arrangement of the first limiting part 161 and the second limiting part 143 ensures that they remain in contact throughout the movement of the lower armature 160, thereby guaranteeing the limiting effect. In other embodiments, optionally, the relative arrangement of the first limiting part 161 and the second limiting part 143 only ensures that they remain in contact during a portion of the movement of the lower armature 160, such as the upper or lower half of the stroke.

[0052] In other embodiments, optionally, a gap is provided between the first limiting part 161 and the second limiting part 143. During the reciprocating motion of the lower bit frame 160, the second limiting part 143 limits the first limiting part 161 to prevent the lower bit frame 160 from swaying left and right during reciprocating motion. During normal movement of the lower bit frame 160, the second limiting part 143 and the first limiting part 161 do not contact each other to avoid affecting the reciprocating motion of the lower bit frame 160. When the lower bit frame 160 sways left and right during reciprocating motion, the second limiting part 143 of the upper bit frame 141 contacts the first limiting part 161 of the lower bit frame 160, thereby using the second limiting part 143 to limit the first limiting part 161.

[0053] In other embodiments, optionally, the first limiting part 161 can be a separate component, connected to the lower armature frame 160 through an installation step; the second limiting part 143 can be a separate component, connected to the upper armature frame 141 through an installation step.

[0054] In other embodiments, optionally, the first limiting part 161 is flat or recessed on the lower armature frame 160, and correspondingly, the second limiting part 143 protrudes toward the first limiting part 161.

[0055] In other embodiments, optionally, the second limiting part 143 is flat or recessed on the upper armature frame 141, and correspondingly, the first limiting part 161 protrudes toward the second limiting part 143.

[0056] In other embodiments, optionally, two legs are formed on each of the left and right sides of the upper arm frame 141, and a second limiting part 143 is provided on each of the two legs on each side.

[0057] In other embodiments, optionally, two legs are formed on each of the left and right sides of the lower armature frame 160, and a first limiting part 161 is provided on each of the legs on each side.

[0058] Example 2

[0059] This embodiment also provides a relay with a high and low voltage insulation structure. The main structure is the same as that in Embodiment 1. The following mainly describes the different parts.

[0060] like Figure 3 and Figure 4 As shown, the insulating frame 140 includes an upper armature frame 141 and an insulating block 142. The lower armature frame 160 has two legs on each of its left and right sides. Each leg on each side has a first limiting part 161, which protrudes towards the insulating block 142 of the insulating frame 140. The first limiting part 161 of the lower armature frame 160 and the insulating block 142 engage in contact to achieve limiting. In this embodiment, the insulating block 142 is used directly to achieve the limiting effect, simplifying the structure of the upper armature frame 141. Simultaneously, the insulating block 142 also provides insulation isolation between the upper armature frame 141 and the lower armature frame 160, further reducing the risk of breakdown in high and low voltage systems and further improving the safety of the relay during use.

[0061] In this embodiment, the position of the insulating block 142 ensures that it remains in contact with the first limiting part 161 throughout the entire movement of the lower armature frame 160. For example... Figure 3 and Figure 4As shown, the insulating block 142 can be configured as a long strip-shaped component. The lower part of the insulating block 142 is connected to the fixing foot 220, and the lower part of the insulating block 142 is positioned close to the magnetic pole plate 210. The upper part of the insulating block 142 is connected to the upper armature frame 141, and the upper part of the insulating block 142 extends beyond the maximum upward movement position of the first limiting part 161 of the lower armature frame 160, to ensure that the insulating block 142 can maintain contact with the first limiting part 161 throughout the movement of the lower armature frame 160. The upper part of the insulating block 142 can also be configured with other shapes depending on the structure of the legs of the upper armature frame 141, such as... Figure 3 As shown, the lower part of the two insulating blocks 142 on the same side has a large gap, and the upper part of the insulating block 142 is connected to the two legs of the upper armature frame 141. The gap between the two legs is small. Correspondingly, the upper part of the two insulating blocks 142 on the same side also has a small gap. A lateral extension structure can be provided on the upper part of the insulating block 142. At this time, the longitudinal position of the lateral extension structure is higher than the maximum upward movement position of the first limiting part 161, so as to avoid the situation where the lateral extension structure cannot play a limiting role for the first limiting part 161.

[0062] In other embodiments, optionally, the position of the insulating block 142 is such that the insulating block 142 and the first limiting part 161 remain in contact only during a portion of the movement of the lower armature frame 160, such as the upper or lower stroke.

[0063] In other embodiments, optionally, a gap is provided between the first limiting part 161 and the insulating block 142. During the reciprocating motion of the lower armature frame 160, the insulating block 142 limits the first limiting part 161, preventing the lower armature frame 160 from swaying left and right during reciprocating motion. During normal movement of the lower armature frame 160, the insulating block 142 and the first limiting part 161 do not contact each other, avoiding any contact that might affect the reciprocating motion of the lower armature frame 160. Only when the lower armature frame 160 sways left and right during reciprocating motion does the insulating block 142 contact the first limiting part 161 of the lower armature frame 160, thereby using the insulating block 142 to limit the first limiting part 161.

[0064] Example 3

[0065] This embodiment also provides a relay with a high and low voltage insulation structure. The main structure is the same as that in Embodiment 2. The following mainly describes the different parts.

[0066] like Figure 5 and Figure 6As shown, the lower armature frame 160 has two legs on each of its left and right sides, and each leg is provided with a first limiting part 161. The upper armature frame 141 has two legs on each of its left and right sides, with one leg on each side having a second limiting part 143. The second limiting part 143 protrudes towards the first limiting part 161 and has a limiting insulating block 144. The second limiting part 143 contacts and engages with the first limiting part 161 through the limiting insulating block 144. The limiting insulating block 144 also provides insulation isolation between the upper armature frame 141 and the lower armature frame 160, further reducing the risk of breakdown in the high and low voltage systems and further improving the safety of the relay during use. In this embodiment, the limiting insulating block 144 can be fixedly disposed on the first limiting part 161 by integral molding, or the limiting insulating block 144 can adopt a split structure, and after being assembled separately to the first limiting part 161, the limiting insulating block 144 can be fixedly disposed on the first limiting part 161 by means of bonding, welding, riveting or other methods.

[0067] In this embodiment, the position of the limiting insulating block 144 ensures that it remains in contact with the first limiting part 161 throughout the entire movement of the lower armature frame 160. In other embodiments, optionally, the position of the limiting insulating block 144 ensures that the insulating block 142 and the first limiting part 161 remain in contact only during a portion of the movement of the lower armature frame 160, such as the upper or lower half of the movement.

[0068] In other embodiments, optionally, the first limiting part 161 is flat or recessed on the lower armature frame 160, and correspondingly, the second limiting part 143 protrudes toward the first limiting part 161, and the second limiting part 143 contacts and cooperates with the first limiting part 161 through the limiting insulating block 144.

[0069] In other embodiments, optionally, the second limiting part 143 is flat or recessed on the upper armature frame 141, and correspondingly, the first limiting part 161 protrudes toward the second limiting part 143, and the second limiting part 143 contacts and cooperates with the first limiting part 161 through the limiting insulating block 144.

[0070] In other embodiments, optionally, a gap is provided between the first limiting part 161 and the limiting insulating block 144. During the reciprocating motion of the lower armature frame 160, the limiting insulating block 144 limits the first limiting part 161 to prevent the lower armature frame 160 from swaying left and right during reciprocating motion. During normal movement of the lower armature frame 160, the limiting insulating block 144 and the first limiting part 161 do not contact each other to avoid affecting the reciprocating motion of the lower armature frame 160. When the lower armature frame 160 sways left and right during reciprocating motion, the limiting insulating block 144 of the upper armature frame 141 contacts the first limiting part 161 of the lower armature frame 160, thereby using the limiting insulating block 144 to limit the first limiting part 161.

[0071] Example 4

[0072] This embodiment also provides a relay with a high and low voltage insulation structure. The main structure is the same as that of the above embodiment. The following mainly describes the different parts.

[0073] like Figure 7 and Figure 8 As shown, the upper armature 130 is integrally formed within the insulating frame 140. The two sides of the insulating frame 140 are complete and continuous surfaces. Fixing feet 220 are connected to the lower ends of both sides of the insulating frame 140. The fixing feet 220 are fixedly connected to the insulating frame 140 by insertion, hot riveting, bonding, or injection molding. The upper armature 130 is not shown in the figure because it is integrally formed within the insulating frame 140.

[0074] In particular, no limiting structure is provided between the lower armature frame 160 and the insulating frame 140, thereby simplifying the overall structure of the relay.

[0075] The 140 insulation frame, which is made in one piece, has fewer parts, making production and assembly simpler and achieving higher production precision.

[0076] In this embodiment, the insulating frame 140 can be made of materials such as polyvinyl chloride, polyethylene, polyimide, polytetrafluoroethylene, epoxy resin, polycarbonate, polystyrene, etc., which have insulating properties and are easy to mold in one piece.

[0077] Example 5

[0078] This embodiment also provides a relay with a high and low voltage insulation structure. The main structure is the same as that in Embodiment 4. The following mainly describes the different parts.

[0079] like Figure 9 and Figure 10As shown, the insulating frame 140 has two legs on each side, and the lower armature frame 160 has two legs on each side. Each leg on each side has a first limiting part 161. The first limiting part 161 protrudes towards the insulating frame 140. The first limiting part 161 and the insulating frame 140 make contact and cooperate to limit the movement direction of the lower armature frame 160.

[0080] In other embodiments, optionally, two legs are formed on each of the left and right sides of the lower armature frame 160, and each leg is provided with a first limiting part 161.

[0081] In other embodiments, optionally, a gap is provided between the first limiting part 161 and the insulating frame 140. During the reciprocating motion of the lower armature frame 160, the insulating frame 140 limits the first limiting part 161, preventing the lower armature frame 160 from swaying left and right during reciprocating motion. During normal movement of the lower armature frame 160, the insulating frame 140 and the first limiting part 161 do not contact each other, avoiding any contact that might affect the reciprocating motion of the lower armature frame 160. Only when the lower armature frame 160 sways left and right during reciprocating motion does the insulating frame 140 contact the first limiting part 161 of the lower armature frame 160, thereby using the insulating frame 140 to limit the first limiting part 161.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
