[0025] One embodiment of the above-described utility model has at least the following advantages or beneficial effects:
[0026] 1. The relay provided in this application uses a limiting protrusion on the mounting base to engage with a first slot in the fixing frame, thereby forming a limiting structure between the mounting base and the fixing frame in a plane perpendicular to the first direction, and is then bonded together with an adhesive layer. In the plane perpendicular to the first direction, when the fixing frame is subjected to impact or vibration, because the limiting protrusion is located within the first slot, the impact force will act on the limiting protrusion, reducing the impact force on the bonding surface, preventing adhesive cracking, and thus improving the bonding strength between the fixing frame and the mounting base, enhancing its resistance to impact and vibration.
[0027] Furthermore, this structural design can effectively prevent relative movement between the mounting base and the fixing frame in a plane perpendicular to the first direction, thereby providing a stable support foundation for other structural components within the relay.
[0028] 2. In the relay provided in this application, the extension path of the adhesive layer is extended and bent after being restricted by the limiting protrusion in a plane perpendicular to the first direction. Accordingly, the extended adhesive layer increases the bonding area with the mounting base and the fixing frame, improving the bonding effect of the adhesive layer with the mounting base and the fixing frame; the bent adhesive layer can disperse stress from all directions, avoiding stress concentration, thereby extending the service life of the adhesive layer, ensuring the bonding effect, and extending the service life of the relay provided in the embodiments of this application.
[0029] 3. In the relay provided in this application, the second slot can assist in the dispensing operation. Specifically, when dispensing adhesive to the mounting bracket and the mounting base, the wall of the second slot can contain the adhesive, preventing it from overflowing. This allows the adhesive to be effectively poured into the gap between the wall of the first slot and the limiting protrusion through the opening of the first slot located on the bottom wall of the second slot, thereby reducing the difficulty of dispensing and improving the adhesion of the adhesive layer to the mounting base and the mounting bracket.

Detailed Implementation
[0043] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many 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 thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0044] This application provides a relay. For example... Figure 1 As shown, the relay includes a mounting base 100 and a fixing bracket 200. The mounting base 100 has a receiving cavity with an opening on at least one side in a first direction Y. The fixing bracket 200 blocks at least a portion of the opening. It is understood that other structural components within the relay can be assembled into the receiving cavity from the opening. To clearly understand the relay provided in the embodiments of this application, Figure 1 The first direction is indicated by Y.
[0045] Please combine Figure 2 and Figure 3 refer to Figure 1 The structure shown includes a cavity wall with a limiting protrusion 110 extending along the first direction Y; a fixing bracket 200 with a first slot 210 extending along the first direction Y, at least a portion of the limiting protrusion 110 being located within the first slot 210; and a gap d (e.g., d) between the limiting protrusion 110 and the wall of the first slot 210 in a plane perpendicular to the first direction Y. Figure 2 As shown in the figure, the limiting protrusion 110 is bonded to the hole wall of the first slot 210 by an adhesive layer (not shown) filled in the gap d.
[0046] It should be noted that the relay mounting base 100 and the fixing bracket 320 provided in this application embodiment are bonded together with an adhesive layer, which can ensure the connection strength between the mounting base 100 and the fixing bracket 200, so that the two can fit tightly together in a plane perpendicular to the first direction Y.
[0047] When assembling the mounting base 100 and the fixing bracket 200 provided in this application embodiment, the limiting protrusion 110 of the mounting base 100 can be inserted into the first slot 210 along the first direction Y, so that at least a portion of the limiting protrusion 110 after assembly is placed in the first slot 210; then, glue can be applied in the gap d between the limiting protrusion 110 and the first slot 210 to bond the hole wall of the first slot 210 and the limiting protrusion 110 through the glue layer.
[0048] It is worth noting that, because the fixing bracket 200 is provided with the first slot 210, when assembling the fixing bracket 200 relative to the mounting base 100, the assembly position of the limiting protrusion 110 relative to the first slot 210 can be observed relatively intuitively, allowing for a judgment on whether the assembly is in place. This ensures the installation effect of the fixing bracket 200 relative to the mounting base 100, reduces assembly difficulty, and improves assembly efficiency. Moreover, during the subsequent glue application operation, glue can be applied directly through the opening of the first slot 210 into the gap d between the first slot 210 and the limiting protrusion 110, reducing the difficulty of glue application and further improving assembly efficiency.
[0049] It should be noted that the relay provided in this embodiment of the application uses the limiting protrusion 110 to cooperate with the first slot 210, so that the mounting base 100 and the fixing frame 200 form a limiting structure in a plane perpendicular to the first direction Y, and are bonded together with an adhesive layer. In the plane perpendicular to the first direction Y, when the fixing frame 200 is subjected to impact or vibration, since the limiting protrusion 110 is placed in the first slot 210, the impact force will act on the limiting protrusion 110, which can reduce the impact force on the bonding surface, avoid adhesive cracking, and thus improve the bonding strength between the fixing frame 200 and the mounting base 100, and improve the impact and vibration resistance.
[0050] Furthermore, this structural design can effectively prevent relative movement between the mounting base 100 and the fixing frame 200 in a plane perpendicular to the first direction Y, thereby providing a stable support foundation for other structural components within the relay.
[0051] Furthermore, it is worth noting that since at least a portion of the limiting protrusion 110 is located within the first slot 210, the adhesive layer will disperse in the gap d between the limiting protrusion 110 and the first slot 210. In a plane perpendicular to the first direction Y, the extension path of the adhesive layer is extended, thereby increasing the bonding area of the adhesive layer with respect to the mounting base 100 and the fixing bracket 200, which can improve the bonding effect of the adhesive layer with respect to the mounting base 100 and the fixing bracket 200.
[0052] Figure 2 The adhesive path of the layer is illustrated by the dashed line 'a'. Figure 2 As shown, regarding the bonding path of the adhesive layer, the adhesive layer in this embodiment is a non-linear path in the plane perpendicular to the first direction Y. In other words, in the plane perpendicular to the first direction Y, the adhesive layer in this embodiment is bent to disperse stress from all directions, avoid stress concentration, extend the service life of the adhesive layer, and thus ensure the bonding effect and extend the service life of the relay provided in this embodiment.
[0053] In specific configuration, the gap d between the limiting protrusion 110 and the wall of the first slot 210 should not be too large or too small to ensure the bonding effect of the adhesive layer on the mounting base 100 and the fixing bracket 200. In one embodiment, such as Figure 2 As shown, in a plane perpendicular to the first direction Y, the gap d between the limiting protrusion 110 and the wall of the first slot 210 is 0.1mm to 0.3mm to ensure that the adhesive layer forms a uniform and appropriate thickness between the limiting protrusion 110 and the wall of the first slot 210. It should be understood that the gap d between the limiting protrusion 110 and the wall of the first slot 210 at different positions can be the same or different, as long as the gap d is within the range of 0.1mm to 0.3mm.
[0054] It should be noted that if the gap d is too small, the adhesive layer may not be able to fill the gap sufficiently, resulting in weak adhesion between the adhesive layer and the fixing bracket 200 and the mounting base 100. If the gap d is too large, the adhesive layer may be too thick, wasting adhesive and potentially causing adhesive to flow from the gap to other parts, affecting the structural performance of the relay. The range of gap d selected in this embodiment ensures that the adhesive layer is evenly distributed during the bonding process, fully utilizing its adhesive performance.
[0055] For example, the size of the gap d can be set to one of the following values.
[0056] 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm.
[0057] like Figure 4 , Figure 5 and Figure 6As shown, the limiting protrusion 110 can completely penetrate the first slot 210 along the first direction Y to ensure that the adhesive layer has sufficient bonding area between the limiting protrusion 110 and the hole wall of the first slot 210. Of course, the limiting protrusion 110 can also be configured to partially penetrate the first slot 210 along the first direction Y, which will not be described in detail here.
[0058] When setting the structure of the limiting protrusion 110, the structure of the limiting protrusion 110 needs to cooperate with the structure of the first slot 210 to ensure that the limiting protrusion 110 can be effectively placed into the first slot 210 and play a limiting effect.
[0059] In one embodiment, the cross-section of the first slot 210 and the limiting protrusion 110 are both rectangular in a plane perpendicular to the first direction Y. This structural arrangement allows the limiting structure formed by the first slot 210 and the limiting protrusion 110 to perform limiting functions in multiple directions within the plane perpendicular to the first direction Y, thereby improving the connection stability between the mounting base 100 and the fixing frame 200 after adhesive bonding.
[0060] For example, such as Figure 5 As shown, in a plane perpendicular to the first direction Y, one side surface of the limiting protrusion 110 can be connected to the side wall of the mounting base 100. In other words, the limiting protrusion 110 may only have a first surface, a second surface, and a third surface connected in sequence, and the first surface, the second surface, and the third surface are used to be inserted into the first slot 210.
[0061] Alternatively, the limiting protrusion 110 can be a protruding post that protrudes completely along the first direction Y. Specifically, the limiting protrusion 110 can include a first surface, a second surface, a third surface, and a fourth surface that are connected in sequence in a plane perpendicular to the first direction Y.
[0062] In one embodiment of the structure that provides the first slot 210, please refer to... Figure 7 and Figure 9 refer to Figure 10 The structure shown has a first slot 210 with two first openings 211 and one second opening 212. It should be understood that, for a clear understanding of the structure of the first slot 210, Figure 10 In the example, a first opening 211 and a second opening 212 are separated by a dashed box. The other first opening 211 is not shown due to the angle. Figure 10 Internal identifier.
[0063] like Figure 10As shown, two first openings 211 are arranged opposite each other in the first direction Y, and a second opening 212 is located on one side of the fixing frame 200 in a plane perpendicular to the first direction Y, and the second opening 212 connects the two first openings 211. For example, in the plane perpendicular to the first direction Y, as... Figure 9 As shown, the first slot 210 is approximately a U-shaped notch provided in the fixing bracket 200, and at least a portion of the limiting protrusion 110 can be as follows: Figure 5 It is placed inside the U-shaped notch as shown.
[0064] It is understood that the second opening 212 of the first slot 210 provided in this application embodiment is located on the side of the fixing frame 200, specifically on the side of the fixing frame 200 facing the mounting base 100. When applying adhesive to the mounting base 100 and the fixing frame 200, the adhesive can flow from the gap between the first slot 210 and the limiting protrusion 110 through the second opening 212 to other parts of the mounting base 100 and the fixing frame 200, thereby increasing the bonding area between the mounting base 100 and the fixing frame 200, improving the bonding effect between them, and further reducing the possibility of loosening or detachment due to external forces after assembly, thus improving the stability and reliability of the overall structure.
[0065] Please continue to refer to this. Figure 2 As shown in the structure, the other parts of the fixing bracket 200 on both sides of the first slot 210 also have gaps with the mounting base 100 to allow for adhesive bonding. Of course, the size of this gap cannot be too large or too small, and can be set according to requirements, which will not be elaborated here.
[0066] In another embodiment, the first slot 210 may have only the first opening 211 in the above embodiment, wherein one first opening 211 is for the limiting protrusion 110 to pass through, and the other first opening 211 can be used to observe the passing status of the limiting protrusion 110 and for dispensing operations.
[0067] In specific settings, the number and location of the limiting structure formed by the first slot 210 in the relay and the limiting protrusion 110 provided in this application embodiment can be set according to requirements.
[0068] In one embodiment, such as Figure 1 As shown, the fixing bracket 200 has first slots 210 on opposite sides in the second direction Z; the mounting base 100 has limiting protrusions 110 on both sides in the second direction Z, and the limiting protrusions 110 correspond to the first slots 210; the second direction Z is perpendicular to the first direction Y. In order to clearly understand the relay provided in the embodiments of this application, the second direction Z is indicated by Z in each figure.
[0069] As an example, the second opening 212 of each first slot 210 faces the mounting base 100 so that the limiting protrusion 110 provided on the mounting base 100 is inserted into the first slot 210 and effectively bonded by the adhesive layer.
[0070] It should be noted that the limiting protrusion 110 on the mounting base 100 corresponds to the first slot 210 on the fixing frame 200, so as to limit and fix the fixing frame 200 from opposite sides in the second direction Z. This bidirectional limiting structure can enhance the stability of the fixing frame 200 relative to the mounting base 100.
[0071] Meanwhile, by providing first slots 210 on both sides of the fixing bracket 200 in the second direction Z, the area where the mounting base 100 and the fixing bracket 200 are bonded by the adhesive layer can be increased, thereby improving the connection strength, effectively dispersing stress, avoiding stress concentration, and further improving the reliability of the structure.
[0072] It is worth noting that the location of the first slot 210 on each side of the fixing bracket 200 in the second direction Z can be designed according to requirements. To further enhance the limiting effect of the limiting structure on the mounting base 100 and the fixing bracket 200, and to enhance the bonding effect of the adhesive layer on the mounting base 100 and the fixing bracket 200, the number of first slots 210 on each side of the fixing bracket 200 can be at least two. Of course, the number of first slots 210 on each side of the fixing bracket 200 in the second direction Z can be the same or different, and can be set according to specific requirements.
[0073] In another embodiment, please continue to refer to Figure 1 The structure shown has a first slot 210 on each of the opposite sides of the fixing bracket 200 in the second direction Z and on each of the opposite sides of the third direction X; the mounting base 100 has limiting protrusions 110 on each of the two sides of the second direction Z and on each side of the third direction X, and the limiting protrusions 110 correspond to the first slots 210; the second direction Z is perpendicular to the first direction Y; the third direction X is perpendicular to both the second direction Z and the first direction Y. To clearly understand the relay provided in the embodiments of this application, the third direction is indicated by X in the figures.
[0074] It should be noted that the difference between this embodiment and another embodiment is that, in addition to having first slots 210 on both sides of the second direction Z, the fixing bracket 200 also has first slots 210 on both sides of the third direction X, so that the fixing bracket 200 can be effectively limited in two mutually perpendicular directions, and the bonding area between the fixing bracket 200 and the mounting base 100 can be increased, thereby improving the bonding effect between the two and further reducing the possibility of loosening or detachment due to external force after assembly, thus improving the stability and reliability of the overall relay structure.
[0075] It is worth noting that the location of the first slot 210 on each side of the fixing bracket 200 in the third direction X can be designed according to requirements. Similarly, in order to further enhance the limiting effect of the limiting structure on the mounting base 100 and the fixing bracket 200, and to enhance the bonding effect of the adhesive layer on the mounting base 100 and the fixing bracket 200, it can be configured that: along the second direction Z, the number of first slots 210 on each side of the fixing bracket 200 is at least two; along the third direction X, the number of first slots 210 on each side of the fixing bracket 200 is at least two, and the specific details will not be elaborated further.
[0076] In one embodiment, please combine Figures 1 to 7 refer to Figure 8 The structure shown includes a second slot 220 in the mounting bracket 200. The second slot 220 has a third opening 221 and a fourth opening 222. It should be understood that, for a clearer understanding of the structure of the second slot 220, Figure 8 In the example, the third opening 221 and the fourth opening 222 are separated by a dashed box. The third opening 221 is located on the side of the fixing frame 200 facing away from the mounting base 100 in the first direction Y, and the fourth opening 222 is located on the side of the fixing frame 200 in a plane perpendicular to the first direction Y, and the fourth opening 222 is connected to the third opening 221; at least one first slot 210 is provided in the bottom wall 223 of the second slot 220 which is opposite to the third opening 221 in the first direction Y.
[0077] Understandably, the second slot 220 can assist in the dispensing operation. Specifically, when dispensing adhesive between the fixture 200 and the mounting base 100, the wall of the second slot 220 can contain the adhesive, preventing it from overflowing. This allows the adhesive to be effectively poured into the gap between the wall of the first slot 210 and the limiting protrusion 110 through the opening of the first slot 210 on the bottom wall 223, thereby reducing the difficulty of dispensing and improving the bonding effect of the adhesive layer on the mounting base 100 and the fixture 200.
[0078] Furthermore, the fourth opening 222 of the second slot 220 can facilitate the flow of adhesive to the gap between the other parts of the fixing bracket 200 on both sides of the first slot 210 and the mounting base 100, so as to further reduce the bonding difficulty and improve the bonding efficiency.
[0079] It is worth noting that, in conjunction with the structure of the first slot 210, the second slot 220 can be designed in different ways. When the first slot 210 has only the first opening 211, the second slot 220 can have only the third opening 221. The specific details will not be elaborated further.
[0080] In one embodiment, please continue to combine Figure 7 refer to Figure 8As shown in the structure, the bottom wall 223 of the second slot 220 is inclined; the depth of the second slot 220 on the side near the fourth opening 222 is greater than the depth on the side away from the fourth opening 222, so that the adhesive can automatically converge from the shallower to the deeper position during the flow process. Moreover, since the adhesive can flow naturally along the inclined surface, this design can reduce the flow resistance of the adhesive in the second slot 220, thereby increasing the filling speed of the adhesive, ensuring that the adhesive can evenly fill the gap between the side wall of the first slot 210 and the limiting protrusion 110, and even fill the gap between other parts of the fixing bracket 200 on both sides of the first slot 210 and the mounting base 100.
[0081] It is worth noting that the number of first slots 210 located on the bottom wall 223 of the second slot 220 can be set according to requirements. For example... Figure 6 and Figure 7 As shown, it can be configured such that multiple first slots 210 located on each side of the fixing frame 200 are shared on the bottom wall 223 of the same second slot 220, so as to guide adhesive through the same second slot 220.
[0082] Or, such as Figure 5 As shown, it can be configured such that each second slot 220 has only one first slot 210 on its bottom wall 223.
[0083] Of course, the correspondence between the second slot 220 and the first slot 210 located on different sides of the fixing frame 200 can be the same or different, and the specifics will not be elaborated further.
[0084] In one embodiment, such as Figure 11 As shown, the receiving cavity has an opening on one side in the first direction Y; along the first direction Y, the cavity wall of the mounting base 100, which is opposite to the opening, is provided with a first support portion. Figure 11 (not shown in the image); such as Figure 9 The mounting bracket 200 shown is provided with a second support portion 230.
[0085] Please continue to refer to this. Figure 11 As shown in the diagram, the relay provided in this embodiment further includes an armature assembly 300, which includes an armature 310 and a bracket 320. The armature 310 is mounted on the bracket 320, and the bracket 320 has connecting portions 321 on both sides in the first direction Y. One connecting portion 321 is pivotally connected to a first support portion in the mounting base 100, and the other connecting portion 321 is pivotally connected to a second support portion 230 of the fixing frame 200. For example, the second support portion 230 is a slot structure, and the connecting portion 321 is a protruding post structure. This protruding post structure can be inserted into the slot structure to rotate relative to it. Of course, the second support portion 230 can also be a protruding post structure, and the connecting portion 321 can be a slot structure; further details will not be elaborated here.
[0086] It is worth noting that in the relay provided in this application embodiment, the fixing bracket 200 is used to provide support for the armature assembly 300; the limiting protrusion 110 of the mounting base 100 cooperates with the first slot 210 provided in the fixing bracket 200 and is glued together. This structural arrangement can effectively limit the position of the mounting base 100 relative to the fixing bracket 200 in a plane perpendicular to the first direction Y, reducing or even avoiding the possibility of the fixing bracket 200 shaking relative to the mounting base 100 during the swing of the armature assembly 300 around the pivot position, thereby improving the stability and reliability of the overall relay structure.
[0087] It is worth noting that when the first slot 210 is arranged in the fixing frame 200, the swinging trend of the armature assembly 300 can be taken into account, so that the limiting structure formed by the first slot 210 and the limiting protrusion 110 can be effectively limited under the driving action of the armature assembly 300.
[0088] Similarly, when the first slot 210 is arranged on opposite sides of the fixing frame 200 along the second direction Z, if the armature assembly 300 exerts a force on the fixing frame 200 in a certain direction during the swinging process, the second direction Z is preferably perpendicular to that direction.
[0089] As an example, during the rotation of the armature assembly 300 around the pivot position, the fixing frame 200 mainly tends to move along the third direction X. Therefore, by setting the first slot 210 on at least one side of the fixing frame 200 in the second direction Z, the fixing frame 200 can be effectively limited, reducing the possibility of the fixing frame 200 shifting.
[0090] In one embodiment, please refer to... Figure 11 As shown in the structure, the relay provided in this application embodiment also includes a yoke assembly 400, which is fixed relative to the mounting base 100; along the first direction Y, the fixing frame 200 is provided with a positioning groove 240 on the side facing the mounting base 100, and at least a portion of the yoke assembly 400 is inserted into the positioning groove 240.
[0091] It is understood that the yoke assembly 400 is fixed in position relative to the mounting base 100, and the yoke assembly 400 will hardly wobble in the plane perpendicular to the first direction Y. In this embodiment, the fixing frame 200 is inserted into the yoke assembly 400 through the positioning groove 240; in the plane perpendicular to the first direction Y, the yoke assembly 400 performs the main limiting and positioning of the fixing frame 200.
[0092] It is worth noting that, in the plane perpendicular to the first direction Y, the gap between the limiting protrusion 110 and the hole wall of the first slot 210 can also prevent the fixing bracket 200 from over-positioning when it is inserted with the yoke assembly 400, which would prevent the fixing bracket 200 from being unable to complete the connection operation with the yoke assembly 400 or the mounting base 100. This can relax the tolerance requirements of each component, reduce the assembly difficulty, and improve the assembly efficiency.
[0093] In a specific embodiment, such as Figure 11 As shown, the yoke assembly 400 includes two contact portions 410 arranged along a second direction Z, with at least a portion of each contact portion 410 inserted into a corresponding positioning groove 240; the second direction Z is perpendicular to the first direction Y. For example, each contact portion 410 has a protrusion 411 extending along the first direction Y, which is used to engage with the corresponding positioning groove 240.
[0094] In one embodiment, please combine Figure 11 refer to Figure 9 The structure shown has a U-shaped positioning groove 240. The opening of each U-shaped positioning groove 240 faces the other positioning groove 240 to avoid over-positioning of the fixing frame 200 and the two contact parts 410 in the second direction Z. This allows the fixing frame 200 to be finely adjusted relative to the yoke assembly 400 in the second direction Z during assembly, thereby reducing assembly difficulty.
[0095] In one embodiment, please refer to... Figure 11 The structure shown has two armatures 310 in the armature assembly 300, which are spaced apart along the thickness direction. Two contact portions 410 are placed between the two armatures 310 along the third direction X. Each contact portion 410 is used to contact and cooperate with one end of an armature 310 to form a mating surface. The side of one contact portion 410 that is opposite to the other contact portion 410 in the third direction X is used to cooperate with the corresponding armature 310 and form a mating surface. The third direction X is perpendicular to the second direction Z and the first direction Y.
[0096] Furthermore, it is worth noting that the mounting bracket 200 provided in this application embodiment may also have a hollow structure, so as to reduce weight through the hollow structure, or to avoid other structural components inside the relay through the hollow structure.
[0097] Of course, other connection structures for positioning or limiting may also be provided between the fixing frame 200 and the mounting base 100 and / or other structural components within the relay. This connection structure may include mating protrusions and recesses, with one of the protrusions or recesses located on the fixing frame 200 and the other on another structure. Alternatively, this connection structure may be other separately provided connectors, the details of which will not be elaborated further.
