Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric control devices, in particular to a base assembly of a relay and a relay. BACKGROUND

[0002] Some relays include a base and a shell, the shell is covered on the base, the base and the shell are plastic encapsulated by epoxy resin glue, and the epoxy resin glue needs high-temperature baking to solidify.

[0003] However, the relay in the related art has the following disadvantages: due to the relatively weak structure of the base, the base will be deformed inwardly during the high-temperature solidification of the epoxy resin glue, which causes the positions of components (such as static contacts or coil assemblies) on the base to change, thereby causing large fluctuations in the parameters of the relay. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a base assembly of a relay and a relay to solve the above problems, the base assembly has small deformation, and the stability of the relay can be improved.

[0005] In one aspect, a base assembly of a relay is provided,

[0006] The base includes a seat body and a limiting portion arranged on the seat body, the limiting portion has two, and the two limiting portions are distributed along a first direction;

[0007] The support component is arranged on one side of the seat body having the limiting portion and located between the two limiting portions, the support component includes a support plate and two flange structures arranged on the support plate, the two flange structures are respectively located on opposite sides of the support plate in the first direction, the two flange structures respectively correspond to the two limiting portions, and the flange structure abuts against the corresponding limiting portion.

[0008] In one of the embodiments, one side of the seat body having the limiting portion is provided with a groove for accommodating the support component, and a groove wall of the groove in the first direction is the limiting portion.

[0009] In one of the embodiments, the support plate is located at a groove bottom of the groove, and an end of the flange structure away from the support plate extends towards a groove opening of the groove.

[0010] In another aspect, a relay is also provided, which includes a shell and the above-mentioned base assembly, and the shell is covered on the seat body.

[0011] In one embodiment, the device further includes a coil assembly, an insulating barrier, and a contact assembly for electrical connection to an external load circuit. The contact assembly and the grooves in the base assembly are spaced apart along the first direction. The insulating barrier surrounds the slot end of the groove, and the coil assembly is disposed in the area surrounded by the insulating barrier.

[0012] In one embodiment, the coil assembly is disposed on the side of the support plate facing the slot, and the coil assembly is located between the two flange structures.

[0013] In one embodiment, the armature assembly is further included and connected to the coil assembly. At least a portion of the armature assembly is located outside the insulating barrier. The contact assembly includes a movable contact and a stationary contact disposed on the base. The movable contact is used to contact the stationary contact in the same group of contact assemblies. The movable contact is linked to the armature assembly. When the electromagnetic force of the coil assembly changes, it can drive the armature assembly to move relative to the insulating barrier and cause the movable contact to contact or separate from the stationary contact in the same group of contact assemblies.

[0014] In one embodiment, the insulating barrier and the base are an integral structure.

[0015] In one embodiment, the support component further includes two limiting members, both connected to the support plate, the two limiting members being spaced apart along a second direction, at least a portion of the limiting members protruding from the side of the support plate facing away from the seat, the coil assembly including a coil frame disposed between the two limiting members, the second direction forming an angle with the first direction.

[0017] In one embodiment, a coil assembly is further included, the coil assembly including a magnetic conductor, a coil and a coil frame, the coil frame including two flanges spaced apart along a second direction, the second direction forming an angle with the magnetic conductor, the two flanges being respectively connected to the magnetic conductor, the coil being located between the two flanges and wound around the outer periphery of the magnetic conductor.

[0018] In one embodiment, the outer contour of the cross-section of the magnetic conductor is circular or elliptical.

[0019] In one embodiment, the magnetic conductor and the flange are an integral structure.

[0020] In one embodiment, the support component is a yoke.

[0021] The aforementioned relay has two limiting parts on its base, which are distributed along the width of the base. A support component is located between the two limiting parts, and the support component abuts against the two limiting parts one by one through the flange structure on the support component. This allows the support component to support the base along the width of the base, effectively preventing the base from deforming inward when heated. Flanged structures are provided on opposite sides of the support plate. The flange structure increases the overall height of the support component, thereby ensuring the height of the support component supporting the base and improving the support effect of the support component on the base.

[0038] See Figure 1 , Figure 2 and Figure 3 , Figure 1 A perspective view of a relay in some embodiments of this application is shown (the armature assembly has been removed from the figure). Figure 2 for Figure 1 The top view of the relay shown. Figure 3 for Figure 2 A cross-sectional view along the AA direction. An embodiment of this application provides a relay base assembly (hereinafter referred to as the base assembly) for use in a relay. The relay includes a housing and the base assembly.

[0039] The base assembly includes a base 1 and a support component 3. The base 1 includes a seat body 12 and two limiting portions 11 disposed on the seat body 12, spaced apart along a first direction, with a housing covering the seat body 12. The support component 3 is disposed on the side of the seat body 12 with the limiting portions 11, and is located between the two limiting portions 11. The support component 3 includes a support plate 31 and two flange structures 32, each disposed on the support plate 31. The two flange structures 32 are located on opposite sides of the support plate 31 along the first direction, and each flange structure 32 corresponds to one of the two limiting portions 11, with the flange structure 32 abutting against its corresponding limiting portion 11. In this embodiment, the first direction is the width direction of the base 1, i.e., the direction indicated by arrow X in the figure.

[0040] Two limiting parts 11 are provided on the base 12, and the two limiting parts 11 are distributed along the width direction of the base 1. The support member 3 is located between the two limiting parts 11. The flange structure 32 on the support member 3 abuts against the two limiting parts 11 one by one, so that the support member 3 can support the base 1 along the width direction of the base 1. This effectively prevents the base 1 from deforming inward when it is heated. Flanged structures 32 are provided on opposite sides of the support plate 31. The flanged structures 32 can increase the overall height of the support member 3, thereby ensuring the height of the support member 3 supporting the base 1, which is beneficial to improving the support effect of the support member 3 on the base 1.

[0041] See Figure 1 The relay also includes a contact assembly 2, a coil assembly 4, and an armature assembly (not shown in the figure). The contact assembly 2 includes a stationary contact 21 and a moving contact 22 for contacting the stationary contact 21. The stationary contact 21 and the coil assembly 4 are both disposed on the side of the base 1 with the limiting part 11. The armature assembly is linked to the moving contact 22. When the electromagnetic force of the coil assembly 4 changes, it can drive the armature assembly to move and drive the moving contact 22 to contact or separate from the stationary contact 21.

[0042] With the cooperation of the support plate 31, the flange structure 32 and the limiting part 11, the relay of this structure can effectively prevent the base 1 from being concave and deformed, reduce the risk of the position of the components on the base 1 (such as the stationary contact 21 and the coil assembly 4) changing due to the deformation of the base 1, thereby reducing the fluctuation of the relay parameters and making the relay have good stability.

[0043] When the relay includes a housing, the housing covers the base 12, and a cavity is formed between the housing and the base 12. The contact assembly 2, the coil assembly 4 and the armature assembly are all located in the cavity.

[0044] See Figure 3 and Figure 4 The base 12 has a groove 13 for accommodating the support member 3 on one side of the limiting part 11. The groove wall of the groove 13 in the first direction is the limiting part 11. This allows the two flange structures 32 to abut against the two opposite groove walls of the groove 13 in the first direction, ensuring that the support member 3 and the base 1 have sufficient contact area. This helps to disperse the contact stress between the base 1 and the support member 3 and reduce the risk of local deformation of the base 1 and the support member 3.

[0045] See Figure 3The support plate 31 is located at the bottom of the groove 13, and the flange structure 32 extends towards the opening of the groove 13 from the end away from the support plate 31. This allows the support plate 31 to be as close as possible to the bottom of the groove 13, preventing a large gap between the support plate 31 and the base 12 due to the presence of the flange structure 32, thus improving the compactness of the relay's internal structure. Of course, in some other embodiments, the flange structure 32 can also be configured such that the end away from the support plate 31 extends towards the bottom of the groove 13, while the support plate 31 is positioned close to the opening of the groove.

[0046] In practical implementation, when the base 12 is provided with a groove 13 for accommodating the support member 3, one or two protrusions can also be provided on the same groove wall of the groove 13 in the first direction. In this case, one or more protrusions on the same groove wall of the groove 13 in the first direction serve as limiting parts 11. When the groove 13 has two or more protrusions on the same groove wall in the first direction, the protrusions on the same groove wall can be distributed at intervals along the length 1 of the base. In this case, the limiting part 11 is a split structure composed of multiple protrusions. That is, in practical implementation, the limiting part 11 can be a split structure or an integral structure.

[0047] In addition, in actual implementation, a protrusion, such as a protrusion, rib, or plate, can be provided on one side of the seat 12 as a limiting part 11. In this case, it is not necessary to provide a groove 13 on the seat 12, and the structure of the limiting part 11 is not specifically limited here.

[0048] See Figure 1 , Figure 2 and Figure 3 The relay also includes an insulating barrier 6. The contact assembly 2 is used for electrical connection with an external load circuit. The contact assembly 2 and the groove 13 are spaced apart along a first direction. In actual implementation, the stationary contact 21 of the contact assembly 2 is connected to the load circuit. When the electromagnetic force of the coil assembly 4 causes the moving contact 22 to contact the stationary contact 21, the contact assembly 2 achieves electrical connection with the load circuit. The insulating barrier 6 surrounds the slot end of the groove 13, and the coil assembly 4 is disposed in the area surrounded by the insulating barrier 6. By placing the coil assembly 4 in the area surrounded by the insulating barrier 6, which is an insulator, an insulating barrier is formed between the stationary contact 21 and the coil assembly 4, reducing the risk of the coil assembly 4 being electrically conductive by the load circuit. When the relay includes a housing, the insulating barrier 6 is disposed in the cavity between the housing and the base 12.

[0049] In this embodiment, the contact component 2 has two sets, which are distributed at intervals along the first direction. The groove 13 and the insulating barrier 6 are both located between the two sets of contact components 2. The moving contact 22 is used to contact the stationary contact 21 in the same set. The moving contact 22 of the two sets of contact components 2 are electrically connected, and the stationary contact 21 of the two sets of contact components 2 are connected to the load circuit. When the moving contact 22 in the two sets of contact components 2 makes contact with the stationary contact 21 in the same set of contact components 2, the load circuit is turned on.

[0050] Among them, the support component 3 is a yoke iron, which can not only support the base 1, but also increase the driving force of the coil assembly 4 on the armature assembly, thereby improving the efficiency of the coil assembly 4. It is not necessary to separately set the support component 3 and the yoke iron on the base 1, which helps to reduce the space occupied on the base 1 and also saves the materials used in the manufacture of the relay.

[0051] Of course, in other embodiments, the support member 3 may be made of other materials, such as an insulator. There are no specific restrictions on the material of the support member 3.

[0052] See Figure 1 , Figure 2 and Figure 3 In the case where the relay includes an armature assembly, the armature assembly is connected to the base 1, and at least a portion of the armature assembly is located outside the insulating barrier 6. The stationary contact 21 of the contact assembly 2 is disposed on the base 12, and the moving contact 22 is linked to the armature assembly. When the electromagnetic force of the coil assembly 4 changes, it can drive the armature assembly to move relative to the insulating barrier 6, and drive the moving contact 22 to contact or separate from the stationary contact 21 in the same group of contact assemblies 2. In this embodiment, when the coil assembly 4 is supplied with positive and reverse pulse voltages, the armature assembly can rotate relative to the base 1 around the rotating shaft under the action of positive and reverse electromagnetic forces, thereby causing the armature assembly to move relative to the insulating barrier 6. During the movement, the armature assembly can push the moving contact 22 toward the stationary contact 21 until it contacts the stationary contact 21, or push the moving contact 22 toward the direction away from the stationary contact 21 until it separates from the stationary contact 21.

[0053] See Figure 3 The insulating barrier 6 and the base 12 are an integral structure, with the base 12 being an insulating component. The insulating barrier 6 and the base 12 are integrally injection molded, reducing the assembly process between the insulating barrier 6 and the base 12. In addition, it can ensure that there are no gaps at the connection between the insulating barrier 6 and the base 12, preventing the voltage on the stationary contact 21 or the moving contact 22 located outside the insulating barrier 6 from creeping onto the coil assembly 4 through the gap between the insulating barrier 6 and the base 12, thereby effectively improving the insulation barrier performance of the insulating barrier 6.

[0054] SeeFigure 5 and Figure 6 The support component 3 also includes two limiting members, both connected to the support plate 31. The two limiting members are spaced apart along a second direction, and at least a portion of each limiting member protrudes from the side of the support plate 31 facing away from the base 12. The coil assembly 4 includes a coil frame disposed between the two limiting members. The second direction forms an angle with the first direction. In this embodiment, the second direction is perpendicular to the first direction. The first direction is the width direction of the base 1, i.e., the direction indicated by arrow X in the figure, and the second direction is the length direction of the base 1, i.e., the direction indicated by arrow Y in the figure. By providing two limiting members on the support plate 31, the movement of the coil frame along the second direction can be restricted by the interaction of the two limiting members.

[0055] The coil frame includes two flanges 42 spaced apart along a second direction, forming a winding window between the two flanges 42. A support plate 31 is located on one side of the winding window. At least one limiting member has a gap 35 with the flange structure 32. At least one limiting member has a gap 35 with the flange structure 32. At least one portion of the flange 42 is disposed in the gap 35.

[0056] For example, there is a gap 35 between the two limiting members and the flange structure 32, and the two flanges 42 correspond one-to-one with the two limiting members. Part of the flange 42 is disposed in the gap 35 on one side of the corresponding limiting member.

[0057] The gap 35 between the limiting member and the flange structure 32 has the following two functions: on the one hand, the gap 35 avoids the flange 42 of the coil frame, further improving the compactness of the internal structure of the relay; on the other hand, the space reserved on both sides of the support plate 31 is used to form the flange structure 32 by flanges on both sides of the support plate 31 in the first direction.

[0058] See Figure 5 and Figure 6 When the support component 3 includes two limiting members, one of the limiting members is a first limiting member 33 and the other is a second limiting member 34. The first limiting member 33 is provided with a connecting hole 331, and one end of the magnetic conductor 43 passes through one of the flanges 42 and is inserted into the connecting hole 331, so that the support component 3 is connected to the coil assembly 4. The second limiting member 34 includes two limiting blocks 341, which are respectively provided on both sides of the support plate 31 in the first direction, and the pole face of the magnetic conductor 43 is located between the two limiting blocks 341.

[0059] It is understandable that the magnitude of the electromagnetic force generated by coil assembly 4 is related to the ampere-turns of coil 41. Under the condition of constant current, the larger the ampere-turns of coil 41, the stronger the magnetic field generated by coil assembly 4. Therefore, in relay, the number of turns of coil 41 is an important factor affecting the electromagnetic force generated by coil assembly 4.

[0060] In some embodiments, see Figure 6 , Figure 7 and Figure 8 In the case where the relay includes a coil assembly 4, the coil assembly 4 includes a magnetic conductor 43, a coil 41, and a coil frame. The coil frame includes two flanges 42 spaced apart along a second direction. The second direction forms an angle with the first direction. In this embodiment, the second direction is perpendicular to the first direction. The first direction is the width direction of the base 1, i.e., the direction indicated by arrow X in the figure. The second direction is the length direction of the base 1, i.e., the direction indicated by arrow Y in the figure. The coil 41 is enameled wire. The coil 41 is located between the two flanges 42 and is wound around the outer periphery of the magnetic conductor 43, so that the coil 41 is directly wound on the magnetic conductor 43. This type of relay eliminates the insulation layer 44 in the winding window of the coil frame, increasing the space for winding the coil 41 within the limited space of the relay. This is beneficial for increasing the ampere-turns of the coil 41, improving the magnetic conductivity of the coil 41 and the magnetic conductor 43, and increasing the magnetic holding force of the relay, thereby improving the stability of the relay.

[0061] In this embodiment, the outer contour of the cross-section of the magnetic conductor 43 is circular. In this specification, the cross-section of the magnetic conductor 43 refers to the cross-section formed by cutting the magnetic conductor 43 along the first direction. Setting the outer contour of the cross-section of the magnetic conductor 43 to be circular avoids breakage of the coil 41 due to sharp edges on the outer contour of the magnetic conductor 43. Furthermore, setting the outer contour of the cross-section of the magnetic conductor 43 to be circular also increases the space for winding the coil 41, which is beneficial for increasing the ampere-turns of the coil 41.

[0062] Of course, in other embodiments, the outer contour of the cross-section of the magnetic conductor 43 can also be set to be elliptical or rectangular, etc.

[0063] To reduce the assembly process between the iron core and the flange 42, the magnetic conductor 43 and the flange 42 are designed as an integral structure in this embodiment. In actual implementation, the magnetic conductor 43 and the flange 42 are integrally injection molded, which can effectively reduce the risk of the magnetic conductor 43 and the flange 42 becoming loose.

[0064] Of course, in other embodiments, see [reference] Figure 3 Alternatively, an insulating layer 44 can be provided on the outer periphery of the magnetic conductor 43, and the coil 41 can be wound on the insulating layer 44.

[0065] In this embodiment, the magnetic conductor 43 is an iron core. Of course, the magnetic conductor 43 is not limited to an iron core. In other embodiments, the magnetic conductor 43 can also be ferrite or steel core, etc.

[0066] It should be noted that in actual implementation, the distribution direction of the two limiting parts 11 can be flexibly adjusted as needed. For example, the two limiting parts 11 can be set to be distributed at intervals along the length direction of the base 1, so that the supporting member 3 supports the base 1 along the length direction of the base 1. Here, no specific restriction is made on the distribution direction of the two limiting parts 11.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
