[0042] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0043] Embodiment 1

[0044] A relay with a high - voltage and low - voltage insulation structure, as Figure 1 and Figure 2 shown, includes: a high - voltage system, including an upper armature 130 and an insulating frame 140, which are fixedly arranged between the upper armature 130 and the insulating frame 140; a low - voltage system, including a magnetic pole plate 210; 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] The upper armature 130 is fixed by the insulating frame 140, and the insulating frame 140 is used to achieve insulation between the upper armature 130 and the magnetic pole plate 210, so as to realize insulation isolation between the high - voltage system and the low - voltage system, and solve 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 through the metal - made fixed feet 220. The metal - made fixed feet 220 can achieve higher connection strength with the magnetic pole plate 210, so as to ensure the connection effect between the insulating frame 140 and the magnetic pole plate 210, and ensure the firm connection between the insulating frame 140 and the upper armature 130 during the use of the relay.

[0046] As Figure 1 and Figure 2 shown, the high - voltage system not only includes the upper armature 130 and the insulating frame 140, but also includes a lower armature 150, a lower armature frame 160, a static contact 110 and a moving contact piece 120. The lower armature 150 is fixedly arranged on the lower armature frame 160, and the moving contact piece 120 is fixedly arranged between the lower armature 150 and the lower armature frame 160. The low - voltage system not only includes the magnetic pole plate 210, but also includes a static iron core 230, a push rod 240 and a moving iron core 250. Among them, 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, so as to drive the lower armature 150 to move towards or away from the upper armature 130. Among them, the lower armature frame 160 is also provided with an insulating seat, and the insulating seat wraps the lower part of the lower armature frame 160, and insulation isolation between the lower armature frame 160 and the magnetic pole plate 210 is realized through the insulating seat. In other embodiments, optionally, insulation isolation between the lower armature frame 160 and the magnetic pole plate 210 can also be realized through other structures, such as setting corresponding insulating structures on the magnetic pole plate 210.

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

[0048] In this embodiment, as Figure 2 As shown, the fixed foot 220 is fixedly connected to the magnetic pole plate 210 by riveting. In other embodiments, optionally, the fixed foot 220 can also be fixedly connected to the magnetic pole plate 210 by fixing connection means such as welding. In this embodiment, the fixed foot 220 made of a metal material is adopted, which is convenient for realizing fixing connection means such as riveting and welding with the magnetic pole plate 210. Fixing connection means such as riveting and welding can achieve a higher-strength fixing effect, can realize the stable connection between the fixed foot 220 and the magnetic pole plate 210, and can achieve higher reliability during the long-term use of the relay. Among them, the fixed foot 220 can specifically be made of metal materials such as aluminum and steel.

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

[0050] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the lower armature frame 160 is disposed inside the upper armature frame 141. The two sides of the lower armature frame 160 are respectively arranged 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, and a first limiting portion 161 is provided on each leg. The first limiting portion 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, and an insulating block 142 is connected to each leg. A fixing foot 220 is connected to each insulating block 142. Among them, a second limiting portion 143 is provided on one leg on each side, and the second limiting portion 143 protrudes towards the first limiting portion 161. The second limiting portion 143 cooperates with the first limiting portion 161 for limiting. In this embodiment, the first limiting portion 161 and the lower armature frame 160 are integrally formed, and are formed by locally bending the lower armature frame 160; the second limiting portion 143 and the upper armature frame 141 are integrally formed, and are formed by locally bending the upper armature frame 141. In this embodiment, when the moving contact piece 120 and the static contact 110 are in contact and conducting, the upper armature frame 141 and the lower armature frame 160 can also be in conducting contact through the contact cooperation of the first limiting portion 161 and the second limiting portion 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 realizes insulation isolation from the magnetic pole plate 210 through the insulating block 142, and the lower armature frame 160 realizes insulation isolation from the push rod 240 through the insulating seat, thereby realizing 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 portion 161 and the second limiting portion 143 is such that they remain in contact throughout the movement process of the lower armature frame 160 to ensure the limiting effect. In other embodiments, optionally, the relative arrangement of the first limiting portion 161 and the second limiting portion 143 only satisfies being in contact during a partial process of the movement of the lower armature frame 160, such as the upper half stroke or the lower half stroke.

[0052] In other embodiments, optionally, a gap is provided between the first limiting portion 161 and the second limiting portion 143. During the reciprocating movement of the lower armature frame 160, the second limiting portion 143 plays a limiting role on the first limiting portion 161 to prevent the lower armature frame 160 from swaying left and right during the reciprocating movement. When the lower armature frame 160 is moving normally, there is no contact between the second limiting portion 143 and the first limiting portion 161 to avoid the contact between the two affecting the reciprocating movement of the lower armature frame 160; when the lower armature frame 160 sways left and right during the reciprocating movement, the second limiting portion 143 of the upper armature frame 141 contacts the first limiting portion 161 of the lower armature frame 160, so that the second limiting portion 143 plays a limiting role on the first limiting portion 161.

[0053] In other embodiments, optionally, the first limiting portion 161 may be an independent component and is connected to the lower armature holder 160 through an installation step; the second limiting portion 143 may be an independent component and is connected to the upper armature holder 141 through an installation step.

[0054] In other embodiments, optionally, the first limiting portion 161 is flatly arranged or concavely arranged on the lower armature holder 160, and correspondingly, the second limiting portion 143 protrudes towards the first limiting portion 161.

[0055] In other embodiments, optionally, the second limiting portion 143 is flatly arranged or concavely arranged on the upper armature holder 141, and correspondingly, the first limiting portion 161 protrudes towards the second limiting portion 143.

[0056] In other embodiments, optionally, two legs are formed on each of the left and right sides of the upper armature holder 141, and the second limiting portion 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 holder 160, and the first limiting portion 161 is provided on one leg on each side.

[0058] Embodiment 2

[0059] This embodiment also provides a relay with a high and low voltage insulation structure. The main structure is the same as that of Embodiment 1, and the following mainly focuses on the different parts for description.

[0060] As Figure 3 and Figure 4 shown, the insulating holder 140 includes an upper armature holder 141 and an insulating block 142. Two legs are formed on each of the left and right sides of the lower armature holder 160, and the first limiting portion 161 is provided on one leg on each side. The first limiting portion 161 of the lower armature holder 160 protrudes towards the insulating block 142 of the insulating holder 140, and the first limiting portion 161 of the lower armature holder 160 is in contact and cooperation with the insulating block 142 to achieve limiting. In this embodiment, the insulating block 142 is directly used to achieve the limiting effect, which can simplify the structure of the upper armature holder 141. At the same time, the insulating block 142 can also achieve the insulating isolation between the upper armature holder 141 and the lower armature holder 160, further reducing the breakdown risk of the 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 satisfies that it is in contact with the first limiting portion 161 throughout the movement process of the lower armature holder 160. As Figure 3 and Figure 4As shown, the insulating block 142 can be set as a strip-shaped member. The lower part of the insulating block 142 is connected to the fixed foot 220, and the lower part of the insulating block 142 is arranged close to the magnetic pole plate 210. The upper part of the insulating block 142 is connected to the upper armature frame 141. The upper part of the insulating block 142 extends beyond the upward maximum movement position of the first limiting part 161 of the lower armature frame 160, so as to ensure that the insulating block 142 can keep in contact with the first limiting part 161 throughout the movement process of the lower armature frame 160. The upper part of the insulating block 142 can also be set in other shapes according to the structure of the legs of the upper armature frame 141, such as Figure 3 As shown, the distance between the lower parts of the two insulating blocks 142 on the same side is relatively large. The upper part of the insulating block 142 is connected to the two legs of the upper armature frame 141, and the distance between the two legs is relatively small. Correspondingly, the distance between the upper parts of the two insulating blocks 142 on the same side is also relatively small. The upper part of the insulating block 142 can be provided with a horizontally extending structure. At this time, the longitudinal position of the horizontally extending structure is higher than the upward maximum movement position of the first limiting part 161, so as to avoid the situation that the horizontally extending structure cannot play a limiting role on the first limiting part 161.

[0062] In other embodiments, optionally, the position of the insulating block 142 only satisfies that during a partial process of the movement of the lower armature frame 160, such as the upper half stroke or the lower half stroke, the insulating block 142 keeps in contact with the first limiting part 161.

[0063] In other embodiments, optionally, there is a gap between the first limiting part 161 and the insulating block 142. During the reciprocating movement of the lower armature frame 160, the insulating block 142 plays a limiting role on the first limiting part 161 to prevent the lower armature frame 160 from swaying left and right during the reciprocating movement. When the lower armature frame 160 moves normally, there is no contact between the insulating block 142 and the first limiting part 161 to avoid the contact between the two affecting the reciprocating movement of the lower armature frame 160; when the lower armature frame 160 sways left and right during the reciprocating movement, the insulating block 142 contacts the first limiting part 161 of the lower armature frame 160, so as to use the insulating block 142 to play a limiting role on the first limiting part 161.

[0064] Embodiment 3

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

[0066] Such as Figure 5 And Figure 6As shown, two legs are formed on each of the left and right sides of the lower armature frame 160, and a first limiting portion 161 is provided on each leg. Two legs are formed on each of the left and right sides of the upper armature frame 141, and a second limiting portion 143 is provided on one leg of each side. The second limiting portion 143 protrudes towards the first limiting portion 161. A limiting insulating block 144 is provided on the second limiting portion 143, and the second limiting portion 143 is in contact and cooperation with the first limiting portion 161 through the limiting insulating block 144. The limiting insulating block 144 can also achieve insulation isolation between the upper armature frame 141 and the lower armature frame 160, further reducing the breakdown risk of 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 arranged on the first limiting portion 161 by an integral molding method, or the limiting insulating block 144 can adopt a split structure. After being assembled separately to the first limiting portion 161, the limiting insulating block 144 is fixedly arranged on the first limiting portion 161 by bonding, welding, riveting or other methods.

[0067] In this embodiment, the position of the limiting insulating block 144 is such that it remains in contact with the first limiting portion 161 throughout the movement process of the lower armature frame 160. In other embodiments, optionally, the position of the limiting insulating block 144 only satisfies that it remains in contact with the first limiting portion 161 during a partial process of the movement of the lower armature frame 160, such as the upper half stroke or the lower half stroke.

[0068] In other embodiments, optionally, the first limiting portion 161 is arranged flat or concave on the lower armature frame 160. Correspondingly, the second limiting portion 143 protrudes towards the first limiting portion 161, and the second limiting portion 143 is in contact and cooperation with the first limiting portion 161 through the limiting insulating block 144.

[0069] In other embodiments, optionally, the second limiting portion 143 is arranged flat or concave on the upper armature frame 141. Correspondingly, the first limiting portion 161 protrudes towards the second limiting portion 143, and the second limiting portion 143 is in contact and cooperation with the first limiting portion 161 through the limiting insulating block 144.

[0070] In other embodiments, optionally, a gap is provided between the first limiting portion 161 and the limiting insulating block 144. During the reciprocating movement of the lower armature frame 160, the limiting insulating block 144 plays a limiting role on the first limiting portion 161 to prevent the lower armature frame 160 from shaking left and right during reciprocating movement. When the lower armature frame 160 moves normally, there is no contact between the limiting insulating block 144 and the first limiting portion 161 to avoid the contact between the two affecting the reciprocating movement of the lower armature frame 160; when the lower armature frame 160 shakes left and right during reciprocating movement, the limiting insulating block 144 of the upper armature frame 141 comes into contact with the first limiting portion 161 of the lower armature frame 160, so that the limiting insulating block 144 plays a limiting role on the first limiting portion 161.

[0071] Embodiment 4

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

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

[0074] Among them, 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] Using the integrally formed insulating frame 140, the number of parts is less, the production and assembly are simpler, and the production accuracy is higher.

[0076] In this embodiment, the insulating frame 140 can be made of materials with insulating properties and convenient for integral molding, such as polyvinyl chloride, polyethylene, polyimide, polytetrafluoroethylene, epoxy resin, polycarbonate, polystyrene, etc.

[0077] Embodiment 5

[0078] This embodiment also provides a relay with a high-voltage and low-voltage insulation structure. The main structure is the same as that of Embodiment 4, and the following mainly focuses on the different parts for description.

[0079] As Figure 9 and Figure 10As shown, two legs are formed on each side of the insulating frame 140, and two legs are formed on each of the left and right sides of the lower armature frame 160. A first limiting portion 161 is provided on one leg of each side. The first limiting portion 161 protrudes towards the insulating frame 140, and the first limiting portion 161 is in contact and cooperation with the insulating frame 140 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 a first limiting portion 161 is provided on each leg.

[0081] In other embodiments, optionally, a gap is provided between the first limiting portion 161 and the insulating frame 140. During the reciprocating movement of the lower armature frame 160, the insulating frame 140 plays a role in limiting the first limiting portion 161 to prevent the lower armature frame 160 from shaking left and right during reciprocating movement. When the lower armature frame 160 moves normally, there is no contact between the insulating frame 140 and the first limiting portion 161 to avoid the contact between the two affecting the reciprocating movement of the lower armature frame 160; when the lower armature frame 160 shakes left and right during reciprocating movement, the insulating frame 140 comes into contact with the first limiting portion 161 of the lower armature frame 160, so that the insulating frame 140 plays a role in limiting the first limiting portion 161.

[0082] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
