Description

Technical Field

[0001] The present invention relates to the technical field of electronic control devices, and in particular, to a mounting base, a relay, and an assembly method for the relay. Background Art

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is usually applied to an automatic control circuit. In fact, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] A relay mainly includes a magnetic circuit part and a contact part. Both the magnetic circuit part and the contact part are assembled inside the mounting base. In the existing side-mounted mounting base, the opening for assembling the magnetic circuit part and the opening for assembling the contact part are provided on the same side of the mounting base, so that the magnetic circuit part and the contact part can be assembled horizontally from the mounting base. This structural design, on the one hand, results in a larger opening area on the same side of the mounting base, reducing the overall structural strength. On the other hand, the part of the mounting base between the lead-out end of the static contact and the lead-out end of the moving contact is only fixed on one side, which is extremely prone to deformation and even fracture, thereby affecting the product parameters. In the existing vertically-mounted mounting base, the opening for assembling the magnetic circuit part and the opening for assembling the contact part are provided on the top surface of the mounting base. Due to the relatively deep groove depth of the mounting base, there are problems such as difficult assembly of the magnetic circuit part and easy chip scraping. Summary of the Invention

[0055] 3. In the mounting base provided in this application, at least part of the second opening and the third opening are arranged in a staggered manner in the second direction to effectively limit the coil assembly and the armature assembly through the chamber walls on the opposite sides of the openings, enhancing the rationality of the chamber wall layout position and avoiding the area of the direct opposition between the second opening and the third opening from being too large.

[0073] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their detailed descriptions will be omitted.

[0074] Figure 1 The figure shows a three-dimensional structural diagram of the base 100 in the mounting base 10 provided by an embodiment of the present invention; Figure 2 The figure shows Figure 1 a three-dimensional schematic diagram of the base 100 from another angle in Figure 3 The figure shows Figure 1 a three-dimensional schematic diagram of the base 100 from yet another angle in Figure 4 The figure shows an exploded view of the mounting base 10 and other structural components in the relay provided by an embodiment of the present invention; Figure 5 The figure shows Figure 4 an exploded view of the mounting base 10 and other structural components in the relay from another angle in Figure 4 and Figure 5 Refer toFigures 1 to 3 In the structure shown, in a first aspect, an embodiment of the present application provides a mounting base 10. The mounting base 10 includes: a base 100 having a first chamber 110 and a second chamber 120. The first chamber 110 has a first opening on one side in a first direction, and the first opening is used as a mounting opening for the internal contact part 20 of the relay. The second chamber 120 is located on one side of the first chamber 110 in a second direction. The second chamber 120 has a second opening and a third opening in a third direction, and the third opening and the second opening are located on opposite sides of the base 100. The second opening is at least used as a mounting opening for the coil assembly 301 in the internal magnetic circuit part 30 of the relay, and the third opening is at least used as a mounting opening for the armature assembly 302 in the internal magnetic circuit part 30 of the relay. The second direction is perpendicular to the first direction, and the third direction is perpendicular to the first direction and the second direction. To more clearly understand the mounting base 10 provided by the embodiment of the present application, the first direction is now denoted by Z, the second direction is denoted by X, and the third direction is denoted by Y.

[0075] It should be understood that the relay includes a contact part 20 and a magnetic circuit part 30. Among them, the magnetic circuit part 30 includes a coil assembly 301 and an armature assembly 302. The contact part 20 includes a stationary contact 202 and a moving contact 201. The moving contact 201 follows the armature assembly 302 and is used to contact or separate from the stationary contact 202. At least part of the stationary contact 202 and the moving contact 201 are fixed in the first chamber 110.

[0076] Specifically, please combine Figure 4 and Figure 5 reference Figure 2 In the structure shown, when applying the mounting base 10 provided by the embodiment of the present application, the contact part 20 can be assembled into the first chamber 110 from the first opening along a branch direction Z1 of the first direction Z, so that at least part of the contact part 20 is placed in the first chamber 110, and the contact part 20 is positioned and limited by the first chamber 110. At least the coil assembly 301 in the magnetic circuit part 30 is assembled into the second chamber 120 from the second opening along a branch direction Y1 of the third direction Y, and the coil assembly 301 is positioned and limited by the chamber wall of the second chamber 120. At least the armature assembly 302 in the magnetic circuit part 30 is assembled into the second chamber 120 from the third opening along a branch direction Y2 of the third direction Y, and the armature assembly 302 is positioned and limited by the chamber wall of the second chamber 120.

[0077] It should be noted that there are two assembly directions, namely the first direction Z and the third direction Y, for the mounting base 10 provided in the embodiment of the present application. The third direction Y is perpendicular to the first direction Z. If the ground is taken as a reference and the first direction Z is defined as the vertical direction, then the third direction Y can be understood as the horizontal direction. Accordingly, when assembling the relay provided in the embodiment of the present application, the contact part 20 is vertically assembled relative to the mounting base 10, and the magnetic circuit part 30 is laterally assembled relative to the mounting base 10.

[0078] It should be noted that by setting the first opening of the first chamber 110 on one side in the first direction Z, the mounting base 10 provided in the embodiment of the present application enables the contact part 20 to be assembled into the first chamber 110 along the first direction Z, and enables the contact part 20 to pass through the first chamber 110 from the opposite side of the first opening in the first direction Z. Accordingly, in the plane perpendicular to the first direction Z, the chamber wall of the first chamber 110 forms a closed structure or a structure similar to a closed structure, which can improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0079] It can be understood that since the moving contact 201 in the contact part 20 in the first chamber 110 needs to follow the armature assembly 302, and at least part of the contact part 20 is located in the first chamber 110, considering the depth of the contact part 20 inserted into the first chamber 110 along the first direction Z, the first chamber 110 may need to communicate with the second chamber 120, and a connection channel may be provided therebetween. Therefore, in the plane perpendicular to the first direction Z, the chamber wall of the first chamber 110 may form a structure similar to a closed structure, which can be specifically set according to requirements and will not be elaborated here.

[0080] At the same time, by setting the second opening and the third opening of the second chamber 120 on the opposite sides in the third direction Y, the mounting base 10 provided in the embodiment of the present application not only enables the coil assembly 301 and the armature assembly 302 in the magnetic circuit part 30 to be respectively assembled, enhancing the assemblability, but also can control the areas of the second opening and the third opening to be small, so as to improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0081] In addition, when applying the mounting base 10 provided in the embodiment of the present application, the coil assembly 301 and the armature assembly 302 in the magnetic circuit part 30 can be laterally assembled relative to the base 100 along the third direction Y, and the possibility of chip scraping problems occurring between each structural part and the base 100 is reduced.

[0082] Therefore, the mounting base 10 provided by the embodiments of the present application can enhance the structural strength of the mounting base 10 by optimizing its own structure, improve the limiting effect of the mounting base 10 on other structural components, and further improve the service life and safety performance of the relay. At the same time, the mounting base 10 can reduce the assembly difficulty and effectively alleviate or even completely solve the chip scraping problem.

[0083] In one embodiment, please continue to refer to Figure 2 the structure shown in the figure. At least part of the second opening and the third opening are offset in the second direction X, so as to effectively limit the coil assembly 301 and the armature assembly 302 through the cavity walls on the opposite sides of the openings, enhance the rationality of the layout position of the cavity walls, and avoid too large a positive opposite area between the second opening and the third opening. This structural setting can also improve the structural strength of the base 100, prevent deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0084] As Figure 2 and Figure 3 shown in the figure, the cavity wall on the side opposite to the second opening of the second chamber 120 in the third direction Y is used to limit the maximum displacement of the coil assembly 301 in the assembly direction Y1. Similarly, the cavity wall on the side opposite to the third opening of the second chamber 120 in the third direction Y is used to limit the maximum displacement of the armature assembly 302 in the assembly direction Y2. Of course, the cavity wall can be a complete plane, or the cavity wall can be provided with convex parts, concave parts or local hollow structures, which will not be elaborated here.

[0085] In one embodiment, as Figure 2 shown in the figure, the cavity wall of the second chamber 120 is provided with a guiding part 121 extending along the third direction Y, and the extension line of the guiding part 121 penetrates through the second opening to guide the coil assembly 301. Specifically, when assembling the coil assembly 301 from the second opening into the second chamber 120, the guiding part 121 can be used to guide the coil assembly 301.

[0086] It should be noted that the guiding part 121 in the embodiments of the present application can guide the coil assembly 301 to be assembled along a predetermined trajectory and direction, ensure that the coil assembly 301 is assembled in place, and improve the assembly efficiency.

[0087] When setting the guiding part 121, there are various possibilities for the structure of the guiding part 121. In a specific embodiment, as Figure 2 shown in the figure, the guiding part 121 is a chute provided on the cavity wall of the second chamber 120. Of course, a slide rail is provided on the coil assembly 301 to cooperate with the chute. Alternatively, the guiding part 121 can also be a slide rail provided on the cavity wall of the second chamber 120. Correspondingly, a chute is provided on the coil assembly 301 to cooperate with the slide rail, which will not be elaborated here.

[0088] In one embodiment, as Figures 1 to 3 shown, a first through hole 122 is provided on the chamber wall of the second chamber 120 in the first direction Z. The first through hole 122 and the first opening are on the same side of the base 100, and the first through hole 122 is used to form a dispensing port for fixing the coil assembly 301. It should be noted that the connection strength between the dispensed coil assembly 301 and the base 100 can be improved to prevent the coil assembly 301 from shaking relative to the second chamber 120 after assembly, which can improve the structural performance of the relay and even extend its service life.

[0089] In one embodiment, as Figure 2 shown, a first support portion 123 is provided on the chamber wall of the second chamber 120 on the side opposite to the third opening in the third direction Y. The first support portion 123 is used to provide a fixed support point for the swing of the armature assembly 302.

[0090] It should be noted that in the embodiment of the present application, the chamber wall of the second chamber 120 on the side opposite to the third opening in the third direction Y is part of the base 100 and is an integral structure with the base 100. This integral structure setting can further improve the structural strength of the base 100, prevent deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0091] Among them, there are various possible forms for the setting of the first support portion 123. In one embodiment, as Figure 2 shown, the first support portion 123 includes a second through hole. Correspondingly, as an example, as Figure 5 shown, the bracket 3022 of the armature assembly 302 can be provided with a connecting portion formed by a convex portion, and the armature assembly 302 is pivotally connected to the second through hole through the convex portion to realize the swinging function of the armature assembly 302.

[0092] Alternatively, the first support portion 123 can be a concave portion provided on the chamber wall surface, and the armature assembly 302 is pivotally connected to the second through hole through a convex portion to realize the swinging function of the armature assembly 302.

[0093] Of course, the first support portion 123 can also be a convex portion provided on the chamber wall surface. Correspondingly, as an example, the bracket 3022 of the armature assembly 302 can be provided with a connecting portion formed by a concave portion, and the armature assembly 302 is pivotally connected to the first support portion 123 through the concave portion to realize the swinging function of the armature assembly 302.

[0094] In a specific embodiment, in a plane perpendicular to the third direction Y, the cross section of the second through hole is circular to improve the pivotal connection effect between the armature assembly 302 and the second through hole, thereby improving the swinging smoothness of the armature assembly 302 and the structural performance of the relay.

[0095] Figure 6 Shown is a three-dimensional structural schematic diagram of the auxiliary connecting plate 200 inside the mounting base 10 provided by an embodiment of the present invention. Please refer to Figures 1 to 5 for reference Figure 6 In one embodiment, with reference to the structure shown, the base 100 provided by an embodiment of the present application further includes an auxiliary connecting plate 200. The auxiliary connecting plate 200 is detachably connected to the base 100, and the auxiliary connecting plate 200 plugs at least part of the third opening.

[0096] It should be noted that the structural design of the detachable connection between the auxiliary connecting plate 200 and the base 100 in the embodiment of the present application enables the auxiliary connecting plate 200 to be disassembled and assembled relative to the base 100 according to requirements, with stronger flexibility. At the same time, the detachable connection structure form can not only reduce the assembly difficulty but also reduce the manufacturing cost.

[0097] Exemplarily, after the armature assembly 302 is assembled into the second chamber 120, the auxiliary connecting plate 200 is assembled to the base 100 to plug at least part of the third opening, so as to limit the armature assembly 302 in the third direction Y.

[0098] In one embodiment, please refer to Figure 4 and Figure 5 for reference Figure 6 In the structure shown, the auxiliary connecting plate 200 is provided with a second supporting portion 210. The second supporting portion 210 is used to provide another fixed supporting point for the swinging of the armature assembly 302. It should be noted that the auxiliary connecting plate 200 cooperates with the chamber wall of the second chamber 120 to effectively support the armature assembly 302 and enable it to swing stably.

[0099] Among them, there are various possible forms of the setting of the second supporting portion 210. In one embodiment, as Figure 6 shown, the first supporting portion 123 includes a third through hole. Correspondingly, as an example, the bracket 3022 of the armature assembly 302 can be provided with a connecting portion formed by a convex portion, and the armature assembly 302 is pivotally connected to the third through hole through the convex portion to realize the swinging function of the armature assembly 302.

[0100] Alternatively, the second supporting portion 210 can be a concave portion provided on the auxiliary connecting plate 200, and the armature assembly 302 is pivotally connected to the third through hole through a convex portion to realize the swinging function of the armature assembly 302.

[0101] Of course, the second supporting portion 210 can also be a convex portion provided on the auxiliary connecting plate 200. Correspondingly, as an example, the bracket 3022 of the armature assembly 302 can be provided with a connecting portion formed by a concave portion, and the armature assembly 302 is pivotally connected to the second supporting portion 210 through the concave portion to realize the swinging function of the armature assembly 302.

[0102] In a specific embodiment, in a plane perpendicular to the third direction Y, the cross-section of the third through-hole is circular, so as to improve the pivoting effect of the armature assembly 302 and the third through-hole, thereby improving the smoothness of the swing of the armature assembly 302, and even improving the structural performance of the relay.

[0103] There are various possibilities for the detachable connection structure between the auxiliary connecting plate 200 and the base 100. In one embodiment, as Figures 3 to 6 shown, along the third direction Y, the base 100 is provided with a recess 140 whose notch is located on the same side as the third opening. The side of the auxiliary connecting plate 200 facing the base 100 is provided with a protrusion 220, and the protrusion 220 is inserted into the recess 140 to improve the assembly efficiency and reduce the assembly difficulty.

[0104] Among them, the number of the recesses 140 provided on the base 100 can be set according to requirements. For example, it can be one or more. As Figure 5 shown, the base 100 is provided with two recesses 140, the auxiliary connecting plate 200 is provided with two protrusions 220, and the two protrusions 220 are spaced along the first direction Z, and each protrusion 220 is inserted into one recess 140.

[0105] Of course, it can also be set that the base 100 is provided with protrusions, and the auxiliary connecting plate 200 is provided with recesses, and the two are inserted through the protrusions and the recesses. Or, it can also be set that the base 100 is provided with protrusions and recesses at the same time, and the auxiliary connecting plate 200 is provided with recesses and protrusions at the same time, and the corresponding protrusions and recesses on the base 100 and the auxiliary connecting plate 200 are inserted respectively.

[0106] In one embodiment, the base 100 is provided with a connection channel, and the first chamber 110 and the second chamber 120 are communicated through the connection channel to facilitate the connection between the contact part 20 and the armature assembly 302.

[0107] In one embodiment, please refer to Figure 4 and Figure 5 for reference Figure 1 to the structure shown. Along the first direction Z, the chamber wall of the first chamber 110 opposite to the first opening is provided with a fourth through-hole 111 and a fifth through-hole 112. The fourth through-hole 111 is used for at least part of the stationary contact 202 in the contact part 20 to penetrate out of the first chamber 110; the fifth through-hole 112 is used for at least part of the moving contact 201 in the contact part 20 to penetrate out of the first chamber 110. It can be understood that the stationary contact 202 penetrates out through the fourth through-hole 111 to lead out the signal from the bottom of the base 100; the moving contact 201 penetrates out through the fifth through-hole 112 to lead out the signal from the bottom of the base 100.

[0108] It is worth noting that the static contact 202 in the contact part 20 and the hole wall of the fourth through hole 111 as well as the dynamic contact 201 and the hole wall of the fifth through hole 112 need to be fixed by glue dispensing to improve the stability of the static contact 202 and the dynamic contact 201 after installation relative to the base 100, avoid the static contact 202 and the dynamic contact 201 from shaking relative to the first chamber 110, and ensure that the dynamic contact 201 can effectively contact or detach from the static contact 202, thereby improving the structural performance of the relay and even extending its service life.

[0109] It is worth noting that after the contact part 20 is loaded into the first chamber 110, it is necessary to glue and fix the static contact 202 and the fourth through hole 111 as well as the dynamic contact 201 and the fifth through hole 112 in the contact part 20 from the side of the first opening. In the embodiment of the present application, the first through hole 122 and the first opening are arranged on the same side of the base 100, so that the glue dispensing equipment can directly dispense glue on the same side of the base 100, thereby reducing the difficulty of the glue dispensing operation and improving the glue dispensing efficiency.

[0110] In one embodiment, the second chamber 120 includes a first sub-chamber and a second sub-chamber connected to the first sub-chamber, the first sub-chamber is located at a side of the second sub-chamber away from the first chamber 110, the first sub-chamber is at least used to install the coil assembly 301 in the magnetic circuit part 30, and the second sub-chamber is at least used to install the armature assembly 302 in the magnetic circuit part 30;

[0111] Please combine Figure 5 refer to Figure 1 and Figure 3 In the structure shown, the base 100 is also provided with a third chamber 130, which is located on the side of the first sub-chamber away from the second opening in the third direction Y; the third chamber 130 is provided with a fourth opening, which is located on the same side of the base 100 as the first opening along the first direction Z, and the fourth opening is used as an installation port for the auxiliary static contact 401 in the auxiliary contact part 40 in the relay.

[0112] It should be noted that the relay provided in the embodiment of the present application rationally plans the space of the base 100, and places the third chamber 130 on the side of the first sub-chamber 131 away from the second opening in the third direction Y, which can reduce the overall volume of the base 100, improve the integration of various components, and facilitate the miniaturization of the relay.

[0113] Meanwhile, it is worth noting that the auxiliary stationary contact 401 in the auxiliary contact part 40 is assembled into the third chamber 130 from the fourth opening along the first direction Z. The auxiliary stationary contact 401 can pass through the third chamber 130 from the opposite side of the fourth opening in the first direction Z. Accordingly, in the plane perpendicular to the first direction Z, the chamber wall of the third chamber 130 forms a closed structure or a structure similar to a closed structure, which can improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0114] In one embodiment, please refer to Figure 5 and Figure 1 the structure shown in Figure 3 The third chamber 130 includes two sub-chambers 131. The two sub-chambers 131 are spaced apart in the second direction X, and the in-chamber depths of the two sub-chambers 131 are different in the first direction Z. It should be noted that the structure setting of the in-chamber depths of the two sub-chambers 131 in the first direction Z in the embodiment of the present application enables the auxiliary moving contact piece 402 to contact the two auxiliary stationary contact pieces 401 respectively. One of the two auxiliary stationary contact pieces 401 is a redundant design, which can enhance the contact reliability. At the same time, this structure setting can reasonably utilize the space inside the relay, improve the integration of the device, and facilitate miniaturization.

[0115] In one embodiment, along the first direction Z, a sixth through hole is provided on the chamber wall of the sub-chamber 131 opposite to the fourth opening for at least part of the auxiliary stationary contact 401 to pass through the third chamber 130.

[0116] It can be understood that the auxiliary stationary contact 401 passes through the third chamber 130 through the sixth through hole to lead out the signal from the bottom of the base 100.

[0117] It is worth noting that the auxiliary stationary contact 401 and the sixth through hole need to be fixed by dispensing to improve the stability of the auxiliary stationary contact 401 relative to the base 100 after installation and prevent the auxiliary stationary contact 401 from shaking relative to the third chamber 130. The dispensing fixation operation between the auxiliary stationary contact 401 and the sixth through hole can be completed synchronously with the dispensing operation of the first through hole 122 and the coil assembly 301, and the dispensing operations of the stationary contact 202 in the contact part 20 with the fourth through hole 111 and the moving contact 201 with the fifth through hole 112, without the need for secondary dispensing, which can reduce the number of dispensing times and improve the assembly efficiency.

[0118] The embodiment of the present application also provides a relay. Please refer to Figures 1 to 6 the relay provided in the embodiment of the present application. The relay includes the mounting base 10 provided by any technical solution in the above first aspect.

[0119] It should be noted that in the relay provided by the embodiment of the present application, the mounting base 10 is arranged such that the first opening of the first chamber 110 is on one side in the first direction Z, so that the contact part 20 can be assembled into the first chamber 110 along the first direction Z, and the contact part 20 can pass through the first chamber 110 from the opposite side of the first opening in the first direction Z. Accordingly, in the plane perpendicular to the first direction Z, the chamber wall of the first chamber 110 forms a closed structure or a structure similar to a closed structure, which can improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0120] Meanwhile, in the relay provided by the embodiment of the present application, the mounting base 10 is arranged such that the second opening and the third opening of the second chamber 120 are on opposite sides in the third direction Y. This not only enables the coil assembly 301 and the armature assembly 302 in the magnetic circuit part 30 to be assembled separately, enhancing the assemblability, but also allows the areas of the second opening and the third opening to be controlled to be relatively small, so as to improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0121] In addition, when assembling using the mounting base 10 provided in the first aspect, the coil assembly 301 and the armature assembly 302 in the magnetic circuit part 30 can be laterally assembled relative to the base 100 along the third direction Y, reducing the possibility of chipping problems occurring between each structural part and the base 100.

[0122] Figure 7 The figure shows a three-dimensional structural schematic diagram of the contact part 20 in the relay provided by the embodiment of the present invention; Figure 8 The figure shows a three-dimensional structural schematic diagram of the coil assembly 301 in the relay provided by the embodiment of the present invention; Figure 9 The figure shows a three-dimensional structural schematic diagram of the armature assembly 302 in the relay provided by the embodiment of the present invention. Please refer to Figures 1 to 6 for reference Figures 7 to 9 In one embodiment, the relay provided by the embodiment of the present application further includes a contact part 20 and a magnetic circuit part 30. The magnetic circuit part 30 includes a coil assembly 301 and an armature assembly 302. At least part of the contact part 20 is installed in the first chamber 110 from the first opening of the mounting base 10, and at least part of the coil assembly 301 is installed in the second chamber 120 from the second opening of the mounting base 10; at least part of the armature assembly 302 is assembled in the second chamber 120 from the third opening of the mounting base 10.

[0123] Figure 10 The figure shows a three-dimensional structural schematic diagram of the contact part 20 assembled to the mounting base 10 in the relay provided by the embodiment of the present invention. Among them, as Figure 10As shown, when the contact part 20 is assembled to the mounting base 10, the contact part 20 is assembled from the first opening into the first chamber 110 along a branch direction Z1 of the first direction Z, so that at least the contact part 20 is placed inside the first chamber 110, and the contact part 20 is positioned and limited by the first chamber 110.

[0124] Figure 11 The figure shows a three-dimensional structural schematic diagram of the coil assembly 301 inside the relay provided by the embodiment of the present invention being assembled to the mounting base 10; Figure 12 The figure shows a three-dimensional structural schematic diagram of the armature assembly 302 inside the relay provided by the embodiment of the present invention being assembled to the mounting base 10. When the coil assembly 301 and the armature assembly 302 are assembled to the mounting base 10, as Figure 11 shown, the coil assembly 301 is assembled from the second opening into the second chamber 120 along a branch direction Y1 of the third direction Y, and the coil assembly 301 can be positioned and limited by the chamber wall of the second chamber 120; as Figure 12 shown, the armature assembly 302 is assembled from the third opening into the second chamber 120 along a branch direction Y2 of the third direction Y, and the armature assembly 302 can be positioned and limited by the chamber wall of the second chamber 120.

[0125] In one embodiment, please refer to Figure 4 and Figure 5 for reference Figure 8 to the structure shown. The magnetic circuit part 30 further includes a yoke iron assembly 303. The yoke iron assembly 303 is fixed to the coil assembly 301, and the yoke iron assembly 303 and the coil assembly 301 are installed in the second chamber 120 from the second opening of the mounting base 10.

[0126] In one embodiment, please refer to Figure 4 and Figure 5 for reference Figure 9 to the structure shown. The armature assembly 302 includes an armature 3021 and a bracket 3022; the armature 3021 is installed on the bracket 3022, and connecting parts are provided on both sides of the bracket 3022 in the third direction Y. One connecting part is pivotally connected to the first support part 123 of the second chamber 120 inside the mounting base 10, and the other connecting part is pivotally connected to the second support part 210 of the auxiliary connecting plate 200 inside the mounting base 10 to realize the swinging function of the armature assembly 302 relative to the base 100.

[0127] In one embodiment, as Figure 9The connecting part shown is a convex part (not numbered) provided on the bracket 3022. One convex part is pivotally connected to the second through hole in the second chamber 120 of the mounting base 10, and the other convex part is pivotally connected to the third through hole in the auxiliary connecting plate 200 in the mounting base 10, so as to simplify the structural design and reduce the assembly difficulty. Of course, the connecting part can also be set as a concave part, and is pivotally connected to the first supporting part 123 as a convex part through the concave part, and is pivotally connected to the second supporting part 210 as a convex part through another concave part, which will not be elaborated here.

[0128] In addition, one connecting part can be set as a convex part and the other connecting part can be set as a concave part, which will not be elaborated here.

[0129] In one embodiment, as Figure 9 and Figure 12 shown, the number of armatures 3021 in the armature assembly 302 is two, and the two armatures 3021 are arranged at intervals in the thickness direction; as Figure 8 and Figure 11 shown, the yoke assembly 303 includes two contact parts 3031. The two contact parts 3031 are located on the opposite sides of the coil assembly 301 in the first direction Z and are fixed relative to the coil assembly 301, and the two contact parts 3031 are arranged between the two armatures 3021 in the second direction X. Each contact part 3031 is used to contact and cooperate with one end of one armature 3021 to form a first contact surface, and each contact part 3031 is used to contact and cooperate with one end of the other armature 3021 to form a second contact surface.

[0130] It should be noted that the yoke assembly 303 in the embodiment of the present application follows the coil assembly 301. In other words, when assembling the coil assembly 301, the yoke assembly 303 is assembled into the second chamber 120 together with the coil assembly 301 from the second opening. As for the contact and cooperation between the yoke assembly 303 and the armature assembly 302 is realized after the armature assembly 302 is assembled.

[0131] It can be understood that "the two contact parts 3031 are fixed relative to the coil assembly 301" means that: after the contact parts 3031 are assembled relative to the coil assembly 301, there is basically no relative movement. Exemplarily, the contact parts 3031 and the coil assembly 301 can be directly fixedly connected through some structural parts (such as riveting) to achieve position fixation; or, the contact parts 3031 and the coil assembly 301 can be position-fixed by plugging or overlapping through some structural parts. Of course, other limiting structures can also be provided between the contact parts 3031 and the coil assembly 301 for position fixation, which will not be elaborated here.

[0132] During operation, when an excitation is applied to the coil assembly 301, the armature 3021 swings under the action of the yoke assembly 303, and one end of each armature 3021 is in contact with a contact portion 3031. When the excitation of the coil assembly 301 is removed, the armature 3021 swings in the opposite direction, causing the other end of each armature assembly 302 to be in contact with a contact portion 3031.

[0133] In other words, taking one contact portion 3031 as an example, when an excitation is applied to the coil assembly 301, one end of an armature 3021 is in contact with one of its side surfaces in the third direction Y. When the excitation of the coil assembly 301 is removed, the armature 3021 swings in the opposite direction, and the same end of another armature 3021 in the first direction Z is in contact with the other side surface of the contact portion 3031 in the third direction Y.

[0134] In one embodiment, please refer to Figure 8 for reference Figure 11 to the structure shown. The coil assembly 301 includes a bobbin 3011 and a coil 3012 wound around the surface of the bobbin 3011. The contact portion 3031 is fixed to one side of the bobbin 3011 in the first direction Z. The bobbin 3011 is bonded to the chamber wall of the second chamber 120 through a dispensing port formed by a first through hole 122 provided in the chamber wall of the second chamber 120.

[0135] Taking the yoke assembly 303 including an iron core as an example, the iron core in the yoke assembly 303 and the contact portion 3031 can be an integral structure or a segmented structure. Exemplarily, when the iron core and the contact portion 3031 are a split structure, the iron core can be passed through the bobbin 3011, and then the contact portion 3031 can be riveted to the side end of the iron core to fix the yoke assembly 303 to the coil assembly 301.

[0136] Taking the yoke assembly 303 not including an iron core as an example, at this time, the yoke assembly 303 only includes the above two contact portions 3031, and only the contact portion 3031 needs to be fixed to the coil assembly 301.

[0137] In one embodiment, the bobbin 3011 is provided with a slide rail, and the slide rail is slidably engaged with a chute provided on the chamber wall of the second chamber 120. When assembling the coil assembly 301 from the second opening into the second chamber 120, the sliding cooperation between the slide rail and the chute can guide the coil assembly 301 to be assembled along a predetermined trajectory and direction, not only ensuring that the coil assembly 301 is assembled in place, but also improving the assembly efficiency.

[0138] Alternatively, the coil assembly 301 can also be provided with a chute. Correspondingly, a slide rail can be provided on the chamber wall of the second chamber 120, and the chute is slidably engaged with the slide rail.

[0139] In one embodiment, please refer to Figure 4 andFigure 5 Reference Figure 7 In the structure shown, the contact part 20 includes a stationary contact 202 and a moving contact 201. At least part of the stationary contact 202 is installed in the first chamber 110, and part of the stationary contact 202 passes through the fourth through-hole 111 provided on the chamber wall of the first chamber 110 and extends outside the first chamber 110; the stationary contact 202 is adhesively bonded to the hole wall of the fourth through-hole 111; at least part of the moving contact 201 is installed in the first chamber 110, and part of the moving contact 201 passes through the fifth through-hole 112 provided on the chamber wall of the first chamber 110 and extends outside the first chamber 110; the moving contact 201 moves with the armature assembly 302 to contact or separate from the stationary contact 202.

[0140] As an example, when applying the relay provided by the embodiment of the present application, when the armature 3021 contacts one contact part 3031 to form a first contact surface, the moving contact 201 separates from the stationary contact 202; conversely, when the same armature 3021 contacts another contact part 3031 to form a second contact surface, the moving contact 201 contacts the stationary contact 202.

[0141] It can be understood that the stationary contact 202 passes through the fourth through-hole 111 to lead out the signal from the bottom of the base 100; the moving contact 201 passes through the fifth through-hole 112 to lead out the signal from the bottom of the base 100.

[0142] It should be noted that the stationary contact 202 in the contact part 20 and the hole wall of the fourth through-hole 111, as well as the moving contact 201 and the hole wall of the fifth through-hole 112, need to be fixed by dispensing to improve the stability of the stationary contact 202 and the moving contact 201 after being installed relative to the base 100, avoid the stationary contact 202 and the moving contact 201 from shaking relative to the first chamber 110, ensure that the moving contact 201 can effectively contact or separate from the stationary contact 202, and further improve the structural performance of the relay and even extend its service life.

[0143] Please continue to refer to Figure 1 Reference Figure 4 and Figure 5In the structure shown, as an example, the movable contact 201 includes a first fixing portion 2011 and an elastic sheet 2012, and the stationary contact 202 includes a second fixing portion 2021, wherein the first fixing portion 2011 of the movable contact 201 is provided with a fifth through hole 112 as the lead-out end of the movable contact 201, and the second fixing portion 2021 of the stationary contact 202 is provided with a fourth through hole 111 as the lead-out end of the stationary contact 202. The second fixing portion 2021 in the stationary contact 202 is located on the side of the first fixing portion 2011 away from the armature assembly 302 in the second direction X, and is spaced apart from the first fixing portion 2011. The second fixing portion 2021 is provided with a stationary contact point 2022. One end of the elastic sheet 2012 is fixed to the first fixed part 2011, and the other end is bent between the first fixed part 2011 and the second fixed part 2021, and the elastic sheet 2012 is provided with a moving contact 2013, which faces the side of the second fixed part 2021 and is used to contact or disengage with the static contact 2022 provided on the side of the second fixed part 2021 facing the first fixed part 2011.

[0144] It is worth noting that the first fixing portion 2011 may be provided with one or more pins to form the lead-out end of the moving contact 201, and the second fixing portion 2021 may be provided with one or more pins to form the lead-out end of the stationary contact 202. Figure 4 As shown, each first fixing portion 2011 is provided with two pins, each pin passes through a fifth through hole 112 ; each second fixing portion 2021 is provided with two pins, each pin passes through a fourth through hole 111 .

[0145] In one embodiment, please combine Figure 4 , Figure 5 refer to Figure 7 In the structure shown, the movable contact 201 is connected to the armature assembly 302 via a push card 203; the push card 203 is detachably connected to the bracket 3022.

[0146] As an example, when the relay provided in the embodiment of the present application is used, the armature 3021 can be used to drive the push card 203 to move along one branch direction in the second direction X, so that the moving contact 201 is disengaged from the static contact 202; conversely, the armature 3021 can be used to drive the push card 203 to move along another opposite branch direction in the second direction X, so that the static contact 202 is in contact with the moving contact 201.

[0147] In one embodiment, please combine Figure 5 refer to Figure 12For the structure shown, the relay provided by the embodiment of the present application further includes an auxiliary contact portion 40. The auxiliary contact portion 40 includes an auxiliary stationary contact 401 and an auxiliary moving contact 402. At least a part of the auxiliary stationary contact 401 is installed in the third chamber 130 of the mounting base 10, and each auxiliary contact piece passes through the sixth through hole on the chamber wall of the third chamber 130 to the outside of the third chamber 130; the auxiliary moving contact 402 follows the armature assembly 302 to contact or separate from the auxiliary stationary contact 401.

[0148] As an example, the auxiliary moving contact 402 follows the armature assembly 302; when the moving contact 201 in the contact portion 20 contacts the stationary contact 202, the auxiliary moving contact 402 contacts the auxiliary stationary contact 401; conversely, when the moving contact 201 separates from the stationary contact 202, the auxiliary moving contact 402 separates from the auxiliary stationary contact 401. The auxiliary moving contact 402 is used to monitor the closed / open state between the moving contact 201 and the stationary contact 202.

[0149] It should be noted that the auxiliary stationary contact 401 in the auxiliary contact portion 40 can be assembled into the third chamber 130 from the fourth opening along the first direction Z, and the auxiliary stationary contact 401 can pass through the third chamber 130 from the opposite side of the fourth opening in the first direction Z. Accordingly, in the plane perpendicular to the first direction Z, the chamber wall of the third chamber 130 forms a closed structure or a structure similar to a closed structure, which can improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0150] Before the armature assembly 302 is assembled into the second chamber 120, the auxiliary moving contact 402 is connected to the armature assembly 302. The auxiliary moving contact 402 moves along the third direction Y with the armature assembly 302 until the armature assembly 302 is assembled in place. It should be noted that when the armature assembly 302 is assembled in place in the second chamber 120, the auxiliary moving contact 402 also moves to a position corresponding to the stationary contact 202 to monitor during the contact and separation process of the moving contact 201 and the stationary contact 202.

[0151] In one embodiment, please refer to Figure 5 reference Figure 12 For the structure shown, the auxiliary contact portion 40 includes two auxiliary stationary contacts 401, and each auxiliary stationary contact 401 is installed in a sub-chamber 131 in the third chamber 130; each auxiliary stationary contact 401 is provided with an auxiliary stationary contact point, and the auxiliary stationary contact points of the two auxiliary stationary contacts 401 are spaced apart in the first direction Z.

[0152] Specifically, when the moving contact 201 in the contact portion 20 contacts the static contact 202, the auxiliary moving contact 402 contacts the auxiliary static contact point of the corresponding auxiliary static contact 401; conversely, when the moving contact 201 separates from the static contact 202, the auxiliary moving contact 402 separates from the auxiliary static contact point of the auxiliary static contact 401.

[0153] It should be noted that the process of the auxiliary moving contact 402 contacting or separating from the auxiliary static contact point of the auxiliary static contact 401 is essentially the process of the auxiliary moving contact point in the auxiliary moving contact 402 contacting or separating from the auxiliary static contact point in the auxiliary static contact 401, which will not be elaborated here.

[0154] In one embodiment, the relay provided by the embodiment of the present application further includes a housing, the housing has a receiving cavity, the receiving cavity has an assembly port, and the base 100 is installed in the receiving cavity from the assembly port; the first opening of the base 100 in the mounting seat 10 and the assembly port are arranged along the first direction Z, and the first opening is located on the side of the cavity wall of the mounting seat 10 facing the receiving cavity.

[0155] It should be noted that the relay provided by the embodiment of the present application can improve the overall structural strength and safety performance of the relay by covering the base 100 and each structural member assembled on the base 100 with the housing.

[0156] The embodiment of the present application also provides an assembly method for a relay. Figure 13 Shown is a flowchart of the assembly method for the relay provided by the embodiment of the present invention; please refer to Figures 1 to 12 Refer to Figure 13 As shown in the figure, this assembly method includes: assembling the contact portion 20 and the magnetic circuit portion 30 into the base 100 in the mounting seat 10, and the method of assembling the contact portion 20 and the magnetic circuit portion 30 into the base 100 in the mounting seat 10 includes:

[0157] Step S1402: Assemble the contact portion 20 into the first chamber 110 of the base 100 from the first opening, and the first opening is located on one side of the base 100 in the first direction Z;

[0158] Step S1404: At least assemble the coil assembly 301 in the magnetic circuit portion 30 into the second chamber 120 of the base 100 from the second opening, the second chamber 120 is located on one side of the first chamber 110 in the second direction X, and the second direction X is perpendicular to the first direction Z;

[0159] Step S1406: At least assemble the armature assembly 302 in the magnetic circuit portion 30 into the second chamber 120 of the base 100 from the third opening, the third opening and the second opening are located on opposite sides of the base 100 in the third direction Y, and the third direction Y is perpendicular to the first direction Z and the second direction X.

[0160] It should be noted that there are two assembly directions, the first direction Z and the third direction Y, in the assembly method provided by the embodiments of the present application. If the assembly of the contact part 20 relative to the base 100 is defined as vertical assembly, then the assembly of the coil assembly 301 and the armature assembly 302 relative to the base 100 can be understood as lateral assembly. Further, the assembly method provided by the embodiments of the present application further divides the lateral assembly, such that the armature assembly 302 and the coil assembly 301 are assembled from the opposite sides of the base 100 in the third direction Y.

[0161] It should be noted that in the assembly method provided by the embodiments of the present application, the contact part 20 is assembled along the first direction Z into the first chamber 110. The contact part 20 can pass through the first chamber 110 from the opposite side of the first opening in the first direction Z. Further, in the plane perpendicular to the first direction Z, the chamber wall of the first chamber 110 forms a closed structure or a structure similar to a closed structure, which can improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0162] Meanwhile, in the assembly method provided by the embodiments of the present application, the coil assembly 301 and the armature assembly 302 are assembled from different branch directions in the third direction Y. This not only enables the coil assembly 301 and the armature assembly 302 in the magnetic circuit part 30 to be assembled separately, enhancing the assemblability, but also enables the areas of the second opening and the third opening of the base 100 to be designed smaller, so as to improve the structural strength of the base 100, avoid deformation, ensure the structural performance of the product, and improve the service life and safety performance of the relay.

[0163] It should be noted that in the assembly method provided by the embodiments of the present application, the contact part 20, the coil assembly 301, and the armature assembly 302 can be assembled according to design requirements.

[0164] In a specific embodiment, the method for assembling the contact part 20 and the magnetic circuit part 30 into the base 100 in the mounting seat 10 includes:

[0165] Performing a first assembly operation to assemble the contact part 20 from the first opening into the first chamber 110 of the base 100;

[0166] Performing a second assembly operation to assemble at least the coil assembly 301 in the magnetic circuit part 30 from the second opening into the second chamber 120 of the base 100;

[0167] Performing a third assembly operation to assemble at least the armature assembly 302 in the magnetic circuit part 30 from the third opening into the second chamber 120 of the base 100.

[0168] It should be noted that in this specific embodiment, the contact part 20, the coil assembly 301, and the armature assembly 302 are sequentially assembled into the mounting base 10 in order.

[0169] In one embodiment, as Figure 8 and Figure 11 shown, the magnetic circuit part 30 further includes a yoke iron assembly 303. The yoke iron assembly 303 includes two contact parts 3031 fixed to the coil assembly 301. During the process of assembling the coil assembly 301 in the magnetic circuit part 30 into the second chamber 120 of the base 100 from the second opening in step S1404, the yoke iron assembly 303 follows the coil assembly 301. In other words, the yoke iron assembly 303 is assembled into the second chamber 120 from the second opening synchronously with the coil assembly 301 to simplify the assembly steps.

[0170] In one embodiment, before performing the method of assembling at least the armature assembly 302 in the magnetic circuit part 30 into the second chamber 120 of the base 100 from the third opening in step S1406, the assembly method further includes:

[0171] Pull the push card 203 connected to the moving contact 201 in the contact part 20 along the second direction X, so that the push card 203 moves away from the first chamber 110; so that the push card 203 can be connected to the armature assembly 302 in subsequent operations. Figure 14 What is shown is Figure 10 the structural schematic diagram of the push card 203 in the contact part 20 after moving. Please refer to Figure 10 the structure in Figure 14 .

[0172] And, at least assemble the armature assembly 302 into the second chamber 120 of the base 100 from the third opening, so that the bracket 3022 in the armature assembly 302 is connected to the push card 203, forming Figure 12 the structure shown.

[0173] When applying the relay assembled by using the assembly method provided in the embodiment of the present application, the armature assembly 302 can drive the push card 203 to move in a branch direction of the second direction X, so that the moving contact 201 is separated from the static contact 202; conversely, the armature assembly 302 can drive the push card 203 to move in the other opposite branch direction of the first direction Z, so that the static contact 202 contacts the moving contact 201.

[0174] In one embodiment, after performing the method of assembling at least the armature assembly 302 in the magnetic circuit part 30 into the second chamber 120 of the base 100 from the third opening in step S1406, the assembly method further includes: assembling the auxiliary connecting plate 200 to the base 100 so that the auxiliary connecting plate 200 blocks at least part of the third opening.

[0175] It should be noted that after the auxiliary connecting plate 200 is assembled to the base 100, at least part of the third opening can be blocked to limit the armature assembly 302 in the third direction Y. At the same time, the auxiliary connecting plate 200 can provide a fixed support point for the swinging of the armature assembly 302.

[0176] In one embodiment, before the method of assembling the armature assembly 302 in at least the magnetic circuit part 30 from the third opening into the second chamber 120 of the base 100 when performing step S1404, the assembling method further includes: assembling the auxiliary static contact 401 in the auxiliary contact part 40 from the fourth opening into the third chamber 130 of the base 100. It should be noted that the step of assembling the auxiliary static contact 401 into the third chamber 130 can occur before the contact part 20 is assembled into the first chamber 110, or before the coil assembly 301 is assembled into the second chamber 120, or before the armature assembly 302 is assembled into the second chamber 120.

[0177] In one embodiment, the auxiliary moving contact 402 in the auxiliary contact part 40 is fixed to the armature assembly 302, and the auxiliary moving contact 402 follows the armature assembly 302 during the process of assembling the armature assembly 302 from the third opening into the second chamber 120 of the base 100 until the assembly is in place, so as to simplify the assembly steps.

[0178] In one embodiment, after the method of assembling the contact part 20 and the magnetic circuit part 30 into the base 100 in the mounting seat 10, the assembling method provided by the embodiments of the present application further includes: performing a dispensing operation on the base 100 by using a dispensing process.

[0179] It should be noted that the glue layer formed after dispensing can improve the stability of each structural member after being installed relative to the base 100, prevent each structural member from shaking relative to the chamber, and further improve the structural performance of the relay and even extend its service life.

[0180] It should be noted that the chamber wall of the second chamber 120 is provided with a first through hole 122 in the first direction Z. The first through hole 122 is on the same side of the base 100 as the first opening, and the first through hole 122 is used to form a dispensing port for fixing the coil assembly 301. In the embodiments of the present application, the first opening, the fourth opening, and the first through hole 122 are all on the same side of the base 100. When performing the dispensing operation, the operation can be carried out from the same side of the base 100, without flipping the base 100, which can simplify the dispensing steps, reduce the dispensing difficulty, and improve the assembly efficiency.

[0181] In the assembling method of the relay provided by the embodiments of the present application, the method of performing a dispensing operation on the base 100 includes:

[0182] Apply glue to the coil assembly 301 and the base 100 through the first through hole 122 of the base 100, apply glue to a part of the static contact 202 passing through the first chamber 110 and the base 100 from the first opening through the fourth through hole 111 of the base 100, apply glue to a part of the moving contact 201 passing through the first chamber 110 and the base 100 from the first opening through the fifth through hole 112 of the base 100, and apply glue to a part of the auxiliary static contact 401 passing through the third chamber 130 and the base 100 from the fourth opening through the sixth through hole of the base 100.

[0183] If the coil assembly 301 and the armature assembly 302 are assembled into the second chamber 120 from the same side of the base 100, since the auxiliary moving contact 402 following the armature assembly 302 will block the glue application operation of the auxiliary static contact 401, the armature assembly 302 needs to be assembled later than the glue application operation of the auxiliary static contact 401. At this time, a glue application operation needs to be performed on the auxiliary static contact 401; after the coil assembly 301 and the armature assembly 302 are assembled into the second chamber 120, a glue application operation needs to be performed again to fix the coil assembly 301 and the base 100. It should be noted that since the auxiliary moving contact 402 in the embodiment of the present application is assembled with the armature assembly 302, and the armature assembly 302 is assembled later than the coil assembly 301, before assembling the auxiliary moving contact 402, the position of the auxiliary static contact 401 is unobstructed, and the auxiliary static contact 401 can perform a glue application operation together with the static contact 202, the moving contact 201, and the coil assembly 301, without the need for secondary glue application, which can reduce the number of glue application times and improve the assembly efficiency.
