[0025] An embodiment of the above invention has at least the following advantages or beneficial effects:

[0026] 1. The mounting seat provided by the present application adopts an integrally formed base and isolation plate group, which reduces the number of parts, not only saving the two processes of applying fixing glue and installing the frame, but also eliminating the original process of press-fitting the frame and the base, that is, avoiding the problems of dimensional control and large cumulative tolerances of the original frame and base, frame and magnetic circuit assembly, and frame and coil assembly. Accordingly, the mounting seat provided by the present application can simplify the production process, reduce the difficulty of assembly, and improve the straight-through rate, thereby reducing the difficulty of assembly when assembling the relay, and improving the assembly efficiency and assembly effect.

[0027] 2. The mounting seat provided in the present application is an integrated structure, and the integrated mounting seat has a positioning function. Specifically, the first partition plate in the mounting seat provided in the present application acts as a stop structure when the yoke and the permanent magnet are assembled from the bottom, so that the yoke and the permanent magnet loaded from the opening of the first mounting groove are effectively positioned and stopped along the first direction, without the need to set other stop structures separately, which can reduce the difficulty of assembly and improve assembly efficiency. Moreover, the yoke and the permanent magnet in the embodiment of the present application are positioned by the first mounting groove, and during the installation process, each structural member does not need to be limited to each other by a clamping force, which can avoid the difficulty of assembling the yoke and the permanent magnet in the related art and the risk of parts damage.

[0028] 3. The isolation plate group in the mounting base provided by the present application can cooperate with the base to play the role of strong and weak electrical isolation. Specifically, the isolation plate group includes a first partition plate and a second partition plate, wherein the first partition plate separates the first mounting groove and the second mounting groove, which can increase the insulation distance between the yoke, the permanent magnet and the coil; the second partition plate separates the second mounting groove and the third mounting groove, which can increase the creepage distance between the coil and the contact part, reduce the risk of creepage breakdown, and improve the safety performance of the relay.

[0029] In addition, it is worth noting that since the first partition effectively separates the first mounting groove from the second mounting groove, the bottom wall of the second mounting groove is not connected to the top wall of the first mounting groove. Accordingly, the creepage distance between the yoke and the permanent magnet installed in the first mounting groove and the contact part can also be increased to reduce the risk of creepage breakdown and improve the safety performance of the relay.

[0030] 4. The second partition in the mounting base provided in the present application separates the second mounting slot and a third mounting slot, which can increase the creepage distance between the coil installed in the second mounting slot and the contact part installed in the third mounting slot, reduce the risk of creepage breakdown, and improve the safety performance of the relay.

[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0044] The present application embodiment provides a relay. Please refer to Figures 1 to 3 In the structure shown, the relay includes a magnetic circuit part and a contact part. The magnetic circuit part includes a magnetic circuit assembly 200 and a coil assembly 300. The magnetic circuit assembly 200 includes a yoke 210, a permanent magnet 220 and an armature 230. The coil assembly 300 includes a coil frame 310, a coil 320 and a coil terminal 330. The coil 320 is wound on the surface of the coil frame 310. The armature 230 passes through the coil frame 310 from the through hole of the coil frame 310.

[0045] As an example, Figure 3As shown, the magnetic circuit assembly 200 includes two yokes 210 arranged opposite to each other, and the armature 230 is placed between the two yokes 210. Along the length direction of the armature 230, one end of the armature 230 can rotate relative to the yoke 210, and the other end can swing relative to the yoke 210, thereby driving the push card 600 to push the contact action. When the coil 320 is energized, the armature 230 swings under the action of the yoke 210, so that it contacts one side of the yoke 210. If a monostable relay is used, when the coil 320 is de-energized, the armature 230 swings in the opposite direction by the reaction force of the spring, so that it contacts the other side of the yoke 210 and returns to the initial disconnected state.

[0046] As an example, Figure 3 As shown, the contact part includes two groups of contact components 500, and the two groups of contact components 500 are located on both sides of the armature 230 along the thickness direction of the armature 230, wherein the specific structures of the two groups of contact components 500 can be the same or different. Taking the two groups of contact components 500 being the same as an example, each group of contact components 500 includes a moving contact component 510 and a static contact component 520, and the moving contact component 510 includes a moving contact bracket 511 and a moving contact piece 512, the moving contact bracket 511 is inserted into the mounting seat 100, and the moving contact piece 512 is installed on the moving contact bracket 511 and moves with the armature 230; the static contact component 520 includes a static contact piece, and the static contact piece is installed on the mounting seat 100. As an example, the moving contact piece 512 moves with the armature 230 by pushing the card 600.

[0047] Please continue to refer to Figure 3 In the structure shown, in some embodiments, the relay further includes a magnetic isolation member 400, and the armature 230 rotates relative to the yoke 210 through the magnetic isolation member 400. As an example, the magnetic isolation member 400 includes two sheet structures and a connecting portion connecting the two sheet structures, each sheet structure is attached to one side of the armature 230 along the thickness direction of the armature 230, and the shape of the sheet structure is adapted to the shape of the surface of the armature 230. Exemplarily, in order to realize the rotation function of the armature 230 relative to the yoke 210, a convex bulge may be provided on the surface of the armature 230, so as to rotate through the convex bulge as a support point. Accordingly, each sheet structure forms a bulge on one side and a depression on the other side, so as to adapt the shape of the bulge through the depression.

[0048] Of course, a convex bristle may also be provided on the yoke 210 to realize the rotation function of the armature 230 relative to the yoke 210 , and the details are not repeated here.

[0049] It is understandable that if Figures 1 to 3 The magnetic circuit assembly 200, the coil assembly 300 and the contact part shown are all mounted on the mounting base 100. It is worth noting that the mounting base 100 can be the mounting base 100 in any of the following technical solutions.

[0050] In order to more clearly understand the mounting seat 100 provided in the embodiment of the present application, the directions in the accompanying drawings are now exemplified. In each figure, Z is used to indicate the first direction, Y is used to indicate the second direction, and X is used to indicate the third direction. The first direction Z, the second direction Y, and the third direction X are perpendicular to each other. It should be understood that the third direction X is roughly parallel to the length direction of the yoke 210, the second direction Y is roughly parallel to the thickness direction of the yoke 210, and the first direction Z is roughly parallel to the height direction of the yoke 210.

[0051] The present application embodiment provides a mounting seat 100. Figures 1 to 3 refer to Figure 4 In the structure shown, the mounting seat 100 includes: an integrally formed base 110 and an isolation plate set 120. As an example, the mounting seat 100 can be integrally formed by an injection molding process to reduce the manufacturing cost and difficulty.

[0052] Please continue to combine Figures 1 to 3 refer to Figures 4 to 8 In the structure shown, the base 110 is provided with Figure 6 and Figure 7 The first mounting groove 111 shown in FIG. Figure 4 and Figure 5 As shown in the second mounting groove 112, the first mounting groove 111 is used to install the yoke 210 and the permanent magnet 220, and the second mounting groove 112 is used to install the coil 320; the isolation plate group 120 includes a first partition plate 121, the first mounting groove 111 and the second mounting groove 112 are separated and independent of each other by the first partition plate 121, and the opening of the first mounting groove 111 and the opening of the second mounting groove 112 are located on opposite sides of the base 110 along the first direction Z; the base 110 is also provided with a third mounting groove 113 for installing the contact part, and the third mounting groove 113 is placed on at least one side of the second mounting groove 112 along the second direction Y; the isolation plate group 120 also includes a second partition plate 122, the second partition plate 122 is connected to the base 110 and extends in the first direction Z away from the base 110, and the second partition plate 122 is located between the third mounting groove 113 and the second mounting groove 112 to separate the second mounting groove 112 from the third mounting groove 113.

[0053] The mounting seat 100 provided in the embodiment of the present application can not only play a role of comprehensive isolation, but also avoid the risk of damage to the precise positioning of the magnetic circuit part. The details are as follows:

[0054] The base and frame in the related art are two isolated structural parts. When in use, the two need to first apply glue to the magnetic circuit assembly 200 and then assemble the frame, which is complicated to operate. Moreover, the magnetic circuit components in the relay need to be assembled on the base from top to bottom, and then the frame is assembled. The mounting seat 100 provided in the embodiment of the present application adopts an integrally formed base 110 and an isolation plate group 120, which reduces the number of parts, not only saves the two processes of applying glue and assembling the frame, but also cancels the original process of press-fitting the frame and the base, that is, avoiding the problems of dimensional control and large cumulative tolerance of the original frame and base, the frame and the magnetic circuit assembly 200, and the frame and the coil assembly 300. Accordingly, the mounting seat 100 provided in the embodiment of the present application can simplify the production process, reduce the difficulty of assembly, and improve the pass rate, thereby reducing the difficulty of assembly when assembling to form a relay, and improving the assembly efficiency and assembly effect.

[0055] It is worth noting that the mounting base 100 in the embodiment of the present application is an integrated structure, and the integrated mounting base 100 has an installation and positioning function.

[0056] When the mounting base 100 provided in the embodiment of the present application is used, there are two opposite mounting surfaces, wherein one mounting surface is located at the opening side of the first mounting groove 111, and the other mounting surface is located at the opening side of the second mounting groove 112. When the opening side of the first mounting groove 111 is the bottom surface of the mounting base 100, the opening side of the second mounting groove 112 is the top surface of the mounting base 100.

[0057] As an example, the yoke 210 and the permanent magnet 220 may be assembled into the first mounting groove 111 from the bottom surface of the mounting base 100 , and the coil 320 may be assembled into the second mounting groove 112 from the top surface of the mounting base 100 .

[0058] It should be noted that the first partition plate 121 in the mounting seat 100 provided in the embodiment of the present application acts as a stop structure when the yoke 210 and the permanent magnet 220 are assembled from the bottom, so that the yoke 210 and the permanent magnet 220 installed from the opening of the first mounting groove 111 are effectively positioned and stopped along the first direction, without the need to set up other stop structures separately, which can reduce the difficulty of assembly and improve the assembly efficiency. Moreover, the yoke 210 and the permanent magnet 220 in the embodiment of the present application are positioned through the first mounting groove 111, and during the installation process, the various structural parts do not need to be limited to each other by the clamping force, which can avoid the difficulty of assembling the yoke and the permanent magnet and the risk of damage to parts in the related art.

[0059] In the actual assembly process, a press-in tool can be designed to replace manual work to press the yoke 210 and the permanent magnet 220 into the first installation groove 111 to achieve automated operation, so as to further improve assembly efficiency and assembly accuracy.

[0060] Please continue to refer to Figure 4 In the structure shown, the isolation plate group 120 in the mounting seat 100 provided in the embodiment of the present application can cooperate with the base 110 to play the role of strong and weak electrical isolation, so as to increase the insulation distance and improve the insulation effect. Specifically, the isolation plate group 120 includes a first partition plate 121 and a second partition plate 122, wherein the first partition plate 121 separates the first mounting groove 111 and the second mounting groove 112, which can increase the insulation distance between the yoke 210, the permanent magnet 220 and the coil 320; the second partition plate 122 separates the second mounting groove 112 and the third mounting groove 113, which can increase the creepage distance between the coil 320 and the contact part, reduce the risk of creepage breakdown, and improve the safety performance of the relay.

[0061] In addition, it is worth noting that, since the first partition 121 effectively separates the first mounting groove 111 from the second mounting groove 112, the bottom wall of the second mounting groove 112 is not connected to the top wall of the first mounting groove 111. Therefore, the creepage distance between the yoke 210 and the permanent magnet 220 installed in the first mounting groove 111 and the contact part can also be increased to reduce the risk of creepage breakdown and improve the safety performance of the relay.

[0062] Based on this, the mounting base 100 provided in the embodiment of the present application can simultaneously realize three groups of creepage layouts for strong and weak electrical isolation, and the isolation effect can be achieved in one step.

[0063] In one embodiment, please combine Fig. 9 and Fig.10 refer to Figures 6 to 8 In the structure shown, the first mounting groove 111 includes two first sub-mounting grooves 1111 and one second sub-mounting groove 1112, the two first sub-mounting grooves 1111 are arranged at intervals along the second direction Y, and each first sub-mounting groove 1111 is used to install a yoke 210; the second sub-mounting groove 1112 is used to install the permanent magnet 220, and the second sub-mounting groove 1112 is placed between the two first sub-mounting grooves 1111 and is connected to at least one first sub-mounting groove 1111. It can be understood that "connected" does not mean that there is no gap between the second sub-mounting groove 1112 and the first sub-mounting groove 1111 at any position. In order to achieve positioning, a small partition structure may be set at some position between the second sub-mounting groove 1112 and the first sub-mounting groove 1111, but these small partition structures do not affect the surface contact between the permanent magnet 220 and the yoke 210.

[0064] It should be noted that, in this embodiment, Fig. 9 and Fig.10 As shown, the two yokes 210 and the permanent magnet 220 can be installed into the first sub-installation groove 1111 from the opening of the first installation groove 111 at the bottom of the base 110, so as to realize the reverse assembly of part of the magnetic circuit.

[0065] It is worth noting that, in this embodiment, the first partition plate 121 for separating the first mounting groove 111 and the second mounting groove 112 cooperates with the base 110 to limit and position the yoke 210 and the permanent magnet 220 in the first direction Z, so as to ensure that the yoke 210 and the permanent magnet 220 are installed in place along the first direction Z. Among them, interference fit can be adopted between the yoke 210 and the first sub-mounting groove 1111 and between the yoke 210 and the second sub-mounting groove 1112 to improve the stability of each structural component after assembly.

[0066] In a specific embodiment, Figure 3 As shown, the yoke 210 is provided with a convex boss 2111, and the yoke 210 is interference fit with the first sub-mounting groove 1111 through the convex boss 2111, so as to transform the larger area of ​​surface contact between the yoke 210 and the first sub-mounting groove 1111 into point-surface contact or line-surface contact or small area of ​​surface contact between the convex boss 2111 and the first sub-mounting groove 1111, thereby reducing the difficulty of assembly and improving the interference fit effect.

[0067] It is worth noting that, in the second direction Y, the yoke 210 may be provided with convex buds 2111 on one side or both sides, and the number of convex buds 2111 on each side of the yoke 210 may be set as required. Figure 3 The yoke 210 shown is provided with two bulges 2111 on each side, and the two bulges 2111 are arranged at intervals in the third direction X.

[0068] In one embodiment, please continue to refer to Figures 6 to 8 In the structure shown, the inner wall of the first sub-mounting groove 1111 is provided with a first protrusion 115 protruding from the inner wall surface of the first sub-mounting groove 1111 along the second direction Y, and the first protrusion 115 is used to abut the side of the yoke 210 to limit the position of the yoke 210 in the second direction Y. It should be understood that the number of the first protrusions 115 can be multiple, and the multiple first protrusions 115 are arranged at intervals to abut different positions of the yoke 210.

[0069] It should be noted that, through the structural design of the first protrusion 115 abutting the yoke 210, surface-to-surface contact between the yoke 210 and the side wall of the first sub-mounting groove 1111 can be avoided, which would make it difficult to insert the yoke 210 along the first direction Z and unable to be installed in place, thereby improving the assembly effect of the yoke 210 in the first sub-mounting groove 1111.

[0070] In specific configuration, the inner wall of each first sub-mounting groove 1111 may be provided with the first protrusion 115 , or only the inner wall of one first sub-mounting groove 1111 may be provided with the first protrusion 115 , and details will not be repeated.

[0071] In one embodiment, please continue to refer to Figure 6and Figure 7 In the structure shown, the inner wall of the second sub-mounting groove 1112 is provided with a second protrusion 117 protruding from the inner wall surface of the second sub-mounting groove 1112 along the third direction X, and the second protrusion 117 is used to abut the side of the permanent magnet 220 to limit the position of the permanent magnet 220 in the third direction X.

[0072] It should be noted that, through the structural design of the second protrusion 117 abutting the permanent magnet 220, surface-to-surface contact between the permanent magnet 220 and the side wall of the second sub-mounting groove 1112 can be avoided, which would make it difficult to insert the permanent magnet 220 along the first direction Z and unable to be installed in place, thereby improving the assembly effect of the permanent magnet 220 in the second sub-mounting groove 1112.

[0073] In specific settings, the second sub-mounting groove 1112 can be provided with a second protrusion 117 on one side of the inner wall surface in the third direction X, or the second sub-mounting groove 1112 can be provided with a second protrusion 117 on both sides of the inner wall surface in the third direction X, and the details are not repeated.

[0074] It is worth noting that the permanent magnet 220 and the second sub-mounting groove 1112 provided with the second protrusion 117 may also be interference-fitted to improve the stability of the permanent magnet 220 after assembly.

[0075] Please inherit the reference Figures 6 to 8 In the structure shown, the second sub-mounting groove 1112 can be connected to at least one first sub-mounting groove 1111, so that the permanent magnet 220 installed in the second sub-mounting groove 1112 contacts the surface of the yoke 210 to play a magnetic conductivity role. Figure 8 As shown, the inner wall of the second sub-mounting groove 1112 is provided with a limiting portion 118 protruding along the first direction Z, and the limiting portion 118 is located at a side edge of the second sub-mounting groove 1112 in the second direction Y to abut against a side surface of the permanent magnet 220 in the second direction Y, so that the permanent magnet 220 and a side yoke 210 are arranged through the gap of the limiting portion 118.

[0076] Specifically, the mounting seat 100 provided in the embodiment of the present application limits the position of the permanent magnet 220 in the second direction Y through the limiting portion 118, so that the permanent magnet 220 is in surface contact with the yoke 210 on one side, and at the same time, a gap is set between the permanent magnet 220 and the yoke 210 on the other side.

[0077] It should be noted that the three iron parts, namely the two yokes 210 and the permanent magnet 220 in the embodiment of the present application, can be precisely positioned through interference fit in the installation grooves. During the installation process, the three iron parts do not need to limit each other through clamping force, which can avoid the difficulties in assembling the yokes and permanent magnets and the risk of parts damage in related technologies.

[0078] Specifically, the solution in the related art is to position the permanent magnet by the distance between the two yokes, which is bound to have interference or clearance fit due to the accumulation of part tolerances, which is not conducive to assemblability. However, the permanent magnet 220 in the embodiment of the present application is assembled through the second sub-mounting groove 1112, and can automatically make surface-to-surface contact with one side of the yoke 210 by relying on the limiting feature of the base 110, which can reduce the degree of dependence on part tolerances and assembly spread.

[0079] Moreover, the integrally formed base 110 and isolation plate assembly 120 in the embodiment of the present application can position and stop the yoke 210 and the permanent magnet 220 in the first assembly direction Z to improve assembly accuracy.

[0080] In a specific embodiment, a guiding slope is provided on the limiting portion 118 to further facilitate the permanent magnet 220 to be assembled in place.

[0081] Since one end of the armature 230 can rotate relative to the yoke 210 along the length direction, and the other end can swing relative to the yoke 210 to respectively snap the yokes 210 on both sides, accordingly, the yoke 210 needs to penetrate from the bottom to the top of the base 110. Please continue to refer to Figure 6 In the structure shown, in one embodiment, the base 110 is provided with a first through hole 116, which is connected to the first sub-mounting groove 1111, and the first through hole 116 is placed on both sides of the second mounting groove 112 along the third direction X to avoid affecting the insulation effect between the yoke 210, the permanent magnet 220 and the coil 320.

[0082] Please combine Figure 3 and Figure 6 refer to Fig. 9 and Fig.10 In the structure shown, each of the two yokes 210 includes two extending arms 211 arranged opposite to each other and a connecting section 212 connecting the two extending arms 211, and the connecting section 212 cooperates with the two extending arms 211 to form a U-shaped structure; each yoke 210 is installed in the first mounting groove 111 from the opening of the first sub-mounting groove 1111 in the first mounting groove 111, and one end of each extending arm 211 away from the connecting section 212 passes through the first through hole 116 of the base 110 in the mounting seat 100 to the other side of the base 110 in the first direction Z, and the two extending arms 211 of each yoke 210 are placed on both sides of the second mounting groove 112 of the mounting seat 100 along the third direction X.

[0083] Among them, in each yoke 210, one extension arm 211 is used to cooperate with the armature 230 to make it rotate, and the other extension arm 211 is used to cooperate with the armature 230 to form a snapping surface.

[0084] It is worth noting that the number of contact components 500 in the contact part is set according to the needs. Figures 1 to 3 refer to Figure 4 and Figure 5 The structure shown is, as an example, when the contact portion includes two contact assemblies 500, in the mounting seat 100, a third mounting slot 113 is provided on each side of the second mounting slot 112 in the second direction Y; a second partition plate 122 is provided between the second mounting slot 112 and each third mounting slot 113. Accordingly, each second partition plate 122 separates the second mounting slot 112 from a third mounting slot 113, which can increase the creepage distance between the coil 320 installed in the second mounting slot 112 and the contact portion installed in the third mounting slot 113, reduce the risk of creepage breakdown, and improve the safety performance of the relay.

[0085] It should be noted that the opening of the third mounting groove 113 is located on the top surface of the base 110 , and the contact portion can be assembled into the third mounting groove 113 from the opening.

[0086] In a specific embodiment, please combine Figure 3 refer to Figure 4 and Figure 5 In the structure shown, the third mounting groove 113 includes a third sub-mounting groove 1131 for mounting the dynamic contact assembly 510 and a fourth sub-mounting groove 1132 for mounting the static contact assembly 520, and the third sub-mounting groove 1131 and the fourth sub-mounting groove 1132 are arranged along the third direction X. It is worth noting that the dynamic contact assembly 510 and the static contact assembly 520 are fixed in different sub-mounting grooves to meet the insulation requirements between the two. Specifically, the distance between the dynamic contact assembly 510 and the static contact assembly 520 needs to be greater than the contact gap to meet the pressure resistance requirements between the contacts.

[0087] It is worth noting that the bottom of the third sub-mounting groove 1131 may be provided with a through hole so that the pin portion of the moving contact bracket 511 in the moving contact assembly 510 can penetrate from the top surface of the base 110 to one side of the bottom surface and be led out. Similarly, the bottom of the fourth sub-mounting groove 1132 may be provided with a through hole so that the pin portion of the stationary contact piece in the stationary contact assembly 520 can penetrate from the top surface of the base 110 to one side of the bottom surface and be led out.

[0088] Please continue to combine Figures 1 to 3 refer to Figure 4 and Figure 5In the structure shown, the coil terminal 330 is connected to the coil 320. The base 110 is also provided with a fourth mounting groove 114 for mounting the coil terminal 330, and the fourth mounting groove 114 is disposed on one side of the second mounting groove 112 along the third direction X. The isolation plate group 120 also includes a third partition plate 123, which is connected to the base 110 and extends away from the base 110 in the first direction Z. The third partition plate 123 is located between the fourth mounting groove 114 and the third mounting groove 113 to separate the fourth mounting groove 114 from the third mounting groove 113.

[0089] It should be noted that the coil terminal 330 is installed in the fourth installation groove 114, and each third partition 123 separates the contact assembly 500 and the coil terminal 330 installed in the third installation groove 113, so as to increase the creepage distance between the coil terminal 330 and the contact part, further reduce the risk of creepage breakdown, and improve the safety performance of the relay.

[0090] It is worth noting that a through hole is provided at the bottom of the fourth mounting groove 114 so that the pin portion of the coil terminal 330 can penetrate from the top surface of the base 110 to one side of the bottom surface and be led out.

[0091] In a specific embodiment, Figure 4 and Figure 5 As shown, along the third direction X, the third partition 123 is connected to one end of the second partition 122, and the third partition 123 is located on the side of the second partition 122 facing the third mounting groove 113, so as to connect the third partition 123 and the second partition 122 into one, avoid the occurrence of creepage gap, thereby further reducing the risk of creepage breakdown and improving the safety performance of the relay.

[0092] Please continue to refer to Figure 4 and Figure 5 In the structure shown, the isolation plate group 120 also includes a fourth partition plate 124, which is connected to the base 110 and extends in the first direction Z away from the base 110, and the fourth partition plate 124 is located between the third mounting groove 113 and the second mounting groove 112 to separate the third mounting groove 113 from the second mounting groove 112, thereby increasing the creepage distance between the coil 320 and the contact part, further reducing the risk of creepage breakdown, and improving the safety performance of the relay.

[0093] In a specific embodiment, the fourth partition 124 is connected to one end of the second partition 122 in the third direction X and is located on the side of the second partition 122 away from the third installation groove 113. Accordingly, the fourth partition 124 can also limit the coil frame 310 along the third direction X to improve the stability of the coil frame 310 after installation.

[0094] The relay provided in the embodiment of the present application further includes a housing, which is used to be assembled with the mounting base 100 to encapsulate some structural parts in the cavity formed by the mounting base 100 and the housing. When assembling the relay provided in the embodiment of the present application, the first mounting groove 111 and the yoke 210 and the permanent magnet 220 can be interference-fitted respectively to achieve precise positioning and pre-positioning, and after the housing is finally put on, the plastic sealing glue is applied again for sealing, thereby reducing the process and production time of applying and baking the fixing glue separately.
