Description

Technical Field

[0001] This application relates to the field of electronic control device technology, and in particular to a relay. Background Technology

[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). Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. In circuits, it plays roles such as automatic adjustment, safety protection, and circuit switching.

[0003] The moving contact component in a relay can contact or move away from the stationary contact component to achieve the switching of current. In traditional technology, a mounting bracket is required to ensure the installation stability of the moving contact component. However, when the relay is subjected to external impact, the moving contact component will exert pressure on the mounting bracket, causing the mounting bracket to deform, which in turn causes the moving contact component to detach from the mounting bracket, affecting the normal use of the relay. Utility Model Content

[0004] Therefore, it is necessary to provide a relay that addresses the problem in traditional technology where the mounting bracket deforms due to external impacts, thus affecting the normal operation of the relay.

[0005] The technical solution is as follows:

[0006] One embodiment provides a relay comprising:

[0007] The mounting bracket includes a first connector, which has a first connecting portion and a first abutting portion.

[0008] The movable contact component and the limiting member are provided. The movable contact component is provided with a first mating part, which is connected to a first connecting part. The first abutting part is used to abut against the limiting member when the first connecting member moves away from the movable contact component, so as to prevent the connection between the first mating part and the first connecting part from failing.

[0009] In the aforementioned relay, the first connecting portion on the first connecting member is connected to the first mating portion on the moving contact assembly. When the relay is subjected to an external impact, the moving contact assembly will compress the first connecting member, causing the first connecting member to move away from the moving contact assembly. This results in a change in the relative position of the first connecting member, leading to a failure in the connection between the first mating portion and the first connecting portion of the moving contact assembly. In this application, the first connecting member is provided with a first abutting portion. The first abutting portion can abut against the limiting member when the first connecting member moves away from the moving contact assembly, preventing the first connecting member from moving further away from the moving contact assembly and causing a failure in the connection between the first mating portion and the first connecting portion, thereby preventing the moving contact assembly from detaching from the mounting bracket. Compared with conventional technology, the aforementioned relay can prevent the moving contact assembly from detaching from the mounting bracket when it is subjected to an external impact, ensuring that the relay can still be used normally after being subjected to an external impact, thereby improving the reliability of the relay.

The second connecting portion is connected to the second mating portion, and the second abutting portion is located on the side of the second connecting portion facing the opening. The second abutting portion is used to abut against the inner wall of the cover when the second connector moves away from the movable contact assembly, so as to prevent the connection between the second mating portion and the second connecting portion from failing.

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] Please see Figures 2 to 6 as well as Figures 9 to 10One embodiment of this application provides a relay, including a mounting bracket 100, a moving contact assembly 200, and a limiting member 30. The mounting bracket 100 includes a first connector 110, which has a first connecting portion 111 and a first abutting portion 112. The moving contact assembly 200 has a first mating portion 210, which is connected to the first connecting portion 111. The first abutting portion 112 is used to abut against the limiting member 30 when the first connector 110 moves away from the moving contact assembly 200, so as to prevent the connection between the first mating portion 210 and the first connecting portion 111 from failing.

[0044] In the aforementioned relay, the first connecting portion 111 on the first connecting member 110 is connected to the first mating portion 210 on the moving contact assembly 200. When the relay is subjected to an external impact, the moving contact assembly 200 will compress the first connecting member 110, causing the first connecting member 110 to move away from the moving contact assembly 200, thereby causing a change in the relative position of the first connecting member 110, resulting in the failure of the connection between the first mating portion 210 and the first connecting portion 111 of the moving contact assembly 200. In this application, the first connecting member 110 is provided with a first abutting portion 112, and the first abutting portion 11... 2. When the first connector 110 moves toward the side away from the moving contact assembly 200, it abuts against the limiting member 30, preventing the first connector 110 from moving further away from the moving contact assembly 200, which would cause the connection between the first mating part 210 and the first connecting part 111 to fail, thereby preventing the moving contact assembly 200 from detaching from the mounting bracket 100. Compared with conventional technology, the above-mentioned relay can prevent the moving contact assembly 200 from detaching from the mounting bracket 100 when it is subjected to external impact, ensuring that the relay can still be used normally after being subjected to external impact, thereby improving the reliability of the relay.

[0045] Furthermore, in one embodiment, the mounting bracket 100 further includes a second connector 120 and a mounting member 130. The first connector 110 and the second connector 120 are spaced apart from the mounting member 130. The first connector 110, the mounting bracket 100, and the second connector 120 surround and form a mounting groove 142 with an opening 141. At least a portion of the movable contact component 200 is located in the mounting groove 142. The limiting member 30 includes a cover 300. At least a portion of the mounting bracket 100 is located in the cover 300. The first abutment portion 112 is located on the side of the first connector 111 facing the opening 141. The first abutment portion 112 is used to abut against the inner wall of the cover 300 when the first connector 110 moves away from the movable contact component 200, so as to prevent the connection between the first mating portion 210 and the first connector 111 from failing.

[0046] When the relay is subjected to an external impact, the moving contact component 200 will compress the first connector 110 and cause the first connector 110 to move away from the moving contact component 200. This will cause the opening 141 of the mounting groove 142 to become larger and cause the moving contact component 200 to detach from the mounting groove 142. In this embodiment, the first connector 110 has a first abutment portion 112 located on the first connecting portion 111 along the opening 141 to one side. The first abutment portion 112 can abut against the inner wall of the cover 300 when the first connector 110 moves away from the moving contact component 200, preventing the first connector 110 from moving further away from the moving contact component 200 and causing the opening 141 to become larger. This prevents the moving contact component 200 from detaching from the mounting groove 142, ensuring that the relay can still be used normally after being subjected to an external impact, thereby improving the reliability of the relay.

[0047] Please see Figures 2 to 6 In one embodiment, the second connector 120 is provided with a second connecting portion 121 and a second abutting portion 122, and the movable contact assembly 200 is also provided with a second mating portion 220. The second connecting portion 121 is connected to the second mating portion 220, and the second abutting portion 122 is located on the side of the second connecting portion 121 facing the opening 141. The second abutting portion 122 is used to abut against the inner wall of the cover 300 when the second connector 120 moves away from the movable contact assembly 200, so as to prevent the connection between the second mating portion 220 and the second connecting portion 121 from failing.

[0048] The second abutting part 122 can abut against the inner wall of the cover 300 when the second connector 120 moves toward the side away from the moving contact assembly 200, so as to prevent the second connector 120 from moving further away from the side away from the moving contact assembly 200 and causing the size of the opening 141 to increase, thereby preventing the connection between the second mating part 220 and the second connecting part 121 from failing and causing the moving contact assembly 200 to detach from the mounting groove 142.

[0049] Please see Figure 2 and Figure 6 In one embodiment, the first connector 110 and the second connector 120 are respectively disposed at opposite ends of the mounting member 130 and extend toward the same side to form a U-shaped mounting bracket 100. The end of the first connector 110 away from the mounting member 130 and the end of the second connector 120 away from the mounting member 130 are spaced apart to form an opening 141. At least a portion of the movable contact assembly 200 is located within the mounting groove 142. Please refer to [link to previous document]. Figure 3When the relay is impacted, the moving contact assembly 200 will compress at least one of the first connector 110 and the second connector 120. The compressed first connector 110 and / or the second connector 120 will move away from the moving contact assembly 200, causing the size of the opening 141 formed by the gap between the first connector 110 and the second connector 120 to increase. This will cause the moving contact assembly 200 in the mounting groove 142 to fall out of the opening 141. By providing a first abutting part 112 and abutting part 122 on the first connector 110 and the second connector 120 respectively, the size of the opening 141 can be prevented from increasing further by the abutting between the first abutting part 112 and the second abutting part 122 and the inner sidewall of the cover 300, thereby preventing the moving contact assembly 200 from falling out of the mounting groove 142.

[0050] Furthermore, the first abutting part 112 is disposed on the side of the first connecting part 111 facing the opening 141, and the second abutting part 122 is disposed on the side of the second connecting part 121 facing the opening 141. Thus, the first abutting part 112 is closer to the opening 141 than the first connecting part 111, and the second abutting part 122 is closer to the opening 141 than the second connecting part 121, making the lever arm longer, thereby enabling it to abut against the inner wall of the cover 300 more promptly to prevent the movable contact component 200 from detaching. Furthermore, before the movable contact component 200 detaches from the first connecting part 111 and / or the second connecting part 121 due to the expansion of the opening 141, the first abutting part 112 and / or the second abutting part 122 is already abutting against the inner wall of the cover 300, thereby ensuring the reliability of the connection between the movable contact component 200 and the first connecting part 111 and the second connecting part 121.

[0051] In one embodiment, the first abutting portion 112 is located on the outer side wall of the mounting bracket 100 and protrudes outward, and the second abutting portion 122 is located on the outer side wall of the mounting bracket 100 and protrudes outward, to ensure the abutting effect.

[0052] Optionally, the first abutting part 112 can be disposed on the first connector 110 by means of bonding, riveting, snap-fitting, integral molding, etc., which is not specifically limited here; similarly, the second abutting part 122 is disposed on the first connector 110, which will not be described in detail here.

[0053] Optionally, the connection between the first connecting part 111 and the first mating part 210 of the moving contact component 200 can be a snap-fit, a plug-in, or the like; similarly, the second connecting part 121 and the second mating part 220 are connected, and will not be described again here.

[0054] Furthermore, the connection between the first connector 110, the second connector 120, and the mounting component 130 can be integrally formed, or it can be other non-integral forming connection methods, which will not be elaborated here.

[0055] In one embodiment, the relay further includes a stationary contact component; the opening 141 of the mounting bracket 100 may be disposed toward or away from the stationary contact component, without specific limitation here.

[0056] Furthermore, the moving contact component 200 can contact or move away from the stationary contact component to achieve the switching of current.

[0057] In one embodiment, the cover 300 has a first inner sidewall and a second inner sidewall that are opposite to each other, the first abutting part 112 is used to abut the first inner sidewall, and the second abutting part 122 is used to abut the second inner sidewall.

[0058] In one embodiment, the cover 300 includes an insulating cover that covers the outside of the mounting bracket 100.

[0059] Alternatively, the cover 300 can be made of ceramic or plastic; no specific limitation is made here.

[0060] In other embodiments, the cover 300 includes a U-shaped fixing frame, and the first abutting part 112 and the second abutting part 122 are respectively used to abut against the two oppositely arranged inner sidewalls of the U-shaped fixing frame.

[0061] Please see Figure 1 In one embodiment, the relay further includes a housing 600, which is disposed outside the enclosure 300.

[0062] Please see Figure 2 and Figure 6 In one embodiment, both the first abutting portion 112 and the second abutting portion 122 are located at the opening 141.

[0063] When the first abutting part 112 and the second abutting part 122 move away from the moving contact assembly 200, the inner wall of the cover 300 can directly abut against the first abutting part 112 and the second abutting part 122 at the opening 141, effectively preventing the size of the opening 141 from further increasing and causing the moving contact assembly 200 to fall off the mounting groove 142.

[0064] Furthermore, both the first contact portion 112 and the second contact portion 122 are located at the outer edge of the opening 141.

[0065] Please see Figure 2 and Figure 6 In one embodiment, the first abutting portion 112 and the second abutting portion 122 are both disposed close to the upper end surface of the moving contact component 200.

[0066] With this configuration, when the movable contact component 200 needs to be assembled into the cover 300, the first abutting part 112 and the second abutting part 122 can preferentially abut against the inner sidewall of the cover 300 and guide it, preventing the movable contact component 200 from being misaligned during the assembly process into the cover 300, which would prevent the movable contact component 200 from being successfully assembled into the cover 300.

[0067] Furthermore, in the above embodiments, the upper end face of the moving contact component 200 is the end face of the moving contact component 200 where the moving contact head is provided, that is, the end face of the moving contact component 200 close to the stationary contact component.

[0068] For explanation, both the first abutting portion 112 and the second abutting portion 122 are disposed close to the upper end surface of the moving contact assembly 200, that is, in Figure 2 From the perspective of the first contact portion 112 and the second contact portion 122, both are located in the middle and upper part of the moving contact assembly 200. Furthermore, both the first contact portion 112 and the second contact portion 122 are located in the uppermost part of the moving contact assembly 200 after it is divided into four equal parts from top to bottom.

[0069] Please see Figure 2 and Figure 4 In one embodiment, the inner sidewall of the cover 300 is provided with a first guide portion 310 and a second guide portion 320. The first guide portion 310 is used to guide and cooperate with the first abutting portion 112, and the second guide portion 320 is used to guide and cooperate with the second abutting portion 122.

[0070] The first abutment portion 112 and the second abutment portion 122, while preventing the size of the opening 141 of the mounting groove 142 from becoming larger, can also achieve guiding cooperation with the first guide portion 310 and the second guide portion 320. This prevents the mounting frame 100 from becoming skewed during the assembly process of the cover 300 and the mounting frame 100, which would prevent the cover 300 and the mounting frame 100 from being assembled smoothly. The guiding cooperation between the first abutment portion 112 and the second abutment portion 122 and the first guide portion 310 and the second guide portion 322, respectively, can ensure that the cover 300 and the mounting frame 100 maintain coaxiality during the assembly process, thereby improving assembly efficiency.

[0071] Further, please refer to Figure 4The cover 300 is provided with a connected assembly cavity 331 and an assembly port 332. The mounting bracket 100 needs to enter the assembly cavity 331 through the assembly port 332 to realize the assembly between the cover 300 and the mounting bracket 100. The first guide part 310 and the second guide part 320 are respectively provided on two opposite side walls of the assembly cavity 331 and extend along the depth direction of the assembly cavity 331. Through the guiding cooperation between the first guide part 310 and the second guide part 320 and the first abutting part 112 and the second abutting part 122 respectively, the cover 300 and the mounting bracket 100 are kept coaxial during the assembly process, thereby improving the assembly efficiency.

[0072] As a further explanation, the assembly cavity 331 of the cover 300 usually has a demolding chamfer, that is, the size of the bottom wall of the assembly cavity 331 is smaller than the size of the assembly opening 332. Therefore, when the mounting bracket 100 needs to be assembled from the assembly opening 332 into the assembly cavity 331, if the mounting bracket 100 is skewed, it is easy to get stuck in the assembly cavity 331, which will prevent smooth assembly. It is necessary to pull the mounting bracket 100 out of the assembly cavity 331 and reassemble it. In this embodiment, the guiding cooperation between the first guide part 310 and the second guide part 320 and the first abutting part 112 and the second abutting part 122 respectively ensures that the cover 300 and the mounting bracket 100 maintain coaxiality during the assembly process, prevents the mounting bracket 100 from being skewed, and improves the assembly efficiency.

[0073] Please see Figures 5 to 8 In one embodiment, at least two first abutting portions 112 are provided and spaced apart on the first connector 110 in a direction perpendicular to the opening 141, and at least two second abutting portions 122 are provided and spaced apart on the second connector 120 in a direction perpendicular to the opening 141, so as to ensure the abutting reliability of the first abutting portions 112 and the second abutting portions 122 with the inner sidewall of the cover 300, thereby further improving the deformation resistance of the mounting bracket 100.

[0074] Furthermore, the number of first guide portions 310 corresponds one-to-one with the number of first abutment portions 112, and the number of second guide portions 320 corresponds one-to-one with the number of second abutment portions 122, so as to improve guiding accuracy and assembly efficiency.

[0075] Please see Figure 2 and Figure 4 In one embodiment, the first guide portion 310 includes a first guide bar, and the second guide portion 320 includes a second guide bar. Both the first guide bar and the second guide bar extend along the orientation of the opening 141.

[0076] The first guide bar and the second guide bar, which extend along the orientation of the opening 141, can respectively guide and cooperate with the first abutment 112 and the second abutment 122 to ensure that the cover 300 and the mounting bracket 100 maintain coaxiality during the assembly process, thereby improving assembly efficiency and reducing implementation costs.

[0077] Furthermore, the first guide bar and the second guide bar extend along the depth direction of the assembly cavity 331.

[0078] Furthermore, both the first guide bar and the second guide bar extend from the assembly cavity 331 of the cover 300 to the assembly opening 332. In this way, when the mounting bracket 100 enters the assembly cavity 331 from the assembly opening 332, it can achieve guiding cooperation with the first guide bar and the second guide bar at the assembly opening 332 to ensure assembly efficiency.

[0079] In one embodiment, at least two first guide bars are provided and correspond one-to-one with the first abutment portion 112, and at least two second guide bars are provided and correspond one-to-one with the second abutment portion 122.

[0080] Please see Figures 5 to 8 In one embodiment, the first abutting portion 112 includes a first arcuate structure 1121, the outer wall of which is used for guiding and engaging with the first guide strip; the second abutting portion 122 includes a second arcuate structure 1221, the outer wall of which is used for guiding and engaging with the second guide strip.

[0081] During the assembly process of the cover 300 and the mounting bracket 100, the outer arc surface of the first arc structure 1121 has the characteristic of smooth transition, which can reduce the friction when in contact with the first guide strip, reduce friction loss and guiding resistance, prevent the generation of chips with the first guide strip during the guiding process, and thus improve the guiding effect; the second arc structure 1221 is similar to the first arc structure 1121, and will not be described in detail here.

[0082] Please see Figures 5 to 8 In one embodiment, the first arcuate structure 1121 is formed by flanging at the opening 141 via the first connector 110.

[0083] This configuration not only ensures the connection strength between the first arc-shaped structure 1121 and the first connector 110, but also reduces production costs.

[0084] Furthermore, the first arc-shaped structure 1121 is formed by flanging the side of the first connector 110 away from the mounting member 130 in a direction away from the second connector 120.

[0085] As an embodiment that can be implemented simultaneously with the above embodiments, the second arc-shaped structure 1221 is formed by flanging at the opening 141 through the second connector 120.

[0086] The second arc-shaped structure 1221 is similar to the first arc-shaped structure 1121, and will not be described again here.

[0087] Please see Figure 2 , Figure 5 as well as Figure 6 In one embodiment, at least one of the first connector 110 and the second connector 120 is provided with an anti-rotation protrusion 150, which is in clearance fit with the inner sidewall of the cover 300 and is used to abut against the inner sidewall of the cover 300 when the moving contact assembly 200 rotates.

[0088] When the moving contact assembly 200 rotates, the anti-rotation protrusion 150 can abut against the inner wall of the cover 300, thereby preventing the moving contact assembly 200 from rotating further, avoiding the moving contact assembly 200 from tilting during the movement and affecting the movement stroke of the moving contact assembly 200, and improving the reliability of the relay.

[0089] Furthermore, the anti-rotation protrusion 150 on the first connector 110 is used to abut against the first guide strip on the inner sidewall of the cover 300, and the anti-rotation protrusion 150 on the second connector 120 is used to abut against the second guide strip on the inner sidewall of the cover 300.

[0090] For illustrative purposes, the application describes the anti-rotation protrusion 150 and the inner wall of the cover 300 as having a gap between them. When the moving contact assembly 200 rotates and moves the anti-rotation protrusion 150, the anti-rotation protrusion 150 abuts against the inner wall of the cover 300, causing the gap between them to disappear.

[0091] Please see Figure 2 and Figure 9 In one embodiment, the relay further includes a drive assembly 500, which includes a push rod 510. The push rod 510 is connected to the moving contact assembly 200 and is used to drive the moving contact assembly 200 to contact or move away from the stationary contact assembly. During this process, the moving contact assembly 200 will rotate around the axis of the push rod 510, thereby driving the mounting bracket 100 to rotate. By providing an anti-rotation protrusion 150 that fits with the inner wall of the cover 300, the moving contact assembly 200 can be prevented from tilting during movement, thus affecting the movement stroke of the moving contact assembly 200 and improving the reliability of the relay.

[0092] Furthermore, the drive assembly 500 also includes an electromagnet unit 520. One end of the push rod 510 is connected to the electromagnet unit 520, and the other end of the push rod 510 is connected to the moving contact assembly 200. Under the driving action of the electromagnet unit 520, the push rod 510 reciprocates along its own axis, thereby driving the moving contact assembly 200 to move, so that the moving contact assembly 200 can come into contact with or move away from the stationary contact assembly.

[0093] Please see Figures 5 to 6 In one embodiment, the first connector 110 is provided with at least two anti-rotation protrusions 150 spaced apart along a direction perpendicular to the opening 141, and the second connector 120 is provided with at least two anti-rotation protrusions 150 spaced apart along a direction perpendicular to the opening 141, so as to ensure the anti-rotation effect.

[0094] Furthermore, the first connector 110 is provided with two anti-rotation protrusions 150 on opposite sides perpendicular to the direction of the opening 141, and the second connector 120 is provided with two anti-rotation protrusions 150 on opposite sides perpendicular to the direction of the opening 141.

[0095] Please see Figures 5 to 6 In one embodiment, the anti-rotation protrusion 150 on the first connector 110 is located between the first abutment portion 112 and the mounting member 130, and the anti-rotation protrusion 150 on the second connector 120 is located between the second abutment portion 122 and the mounting member 130.

[0096] Furthermore, the gap width between the anti-rotation protrusion 150 on the first connector 110 and the inner wall of the cover 300 is smaller than the gap width between the first abutment 112 and the inner wall of the cover 300, and the gap width between the anti-rotation protrusion 150 on the second connector 120 and the inner wall of the cover 300 is smaller than the gap width between the second abutment 122 and the inner wall of the cover 300. Thus, when the movable contact assembly 200 rotates, the anti-rotation protrusion 150 on the first connector 110 can contact the inner wall of the cover 300 before the first abutment 112, and the anti-rotation protrusion 150 on the second connector 120 can contact the inner wall of the cover 300 before the second abutment 122, so as to limit and prevent the movable contact assembly 200 from rotating.

[0097] exist Figures 7 to 8 as well as Figure 10 In the illustrated embodiment, anti-rotation can also be achieved through the contact between the first abutment portion 112 and the second abutment portion 122 and the inner wall of the cover 300. However, since the first abutment portion 112 and the second abutment portion 122 are formed by a flanging process, their surface arcs are relatively irregular, making it easier for them to generate scratches with the inner wall of the cover 300. By achieving anti-rotation through the contact between the anti-rotation protrusion 150 and the inner wall of the cover 300, no scratches will be generated, resulting in better reliability.

[0098] Please see Figures 5 to 10 In one embodiment, the first mating part 210 is provided with a first connecting protrusion 211, the second mating part 220 is provided with a second connecting protrusion 221, the first connecting part 111 is provided with a first connecting hole 1111, the second connecting part 121 is provided with a second connecting hole 1211, the first connecting protrusion 211 is inserted into the first connecting hole 1111, and the second connecting protrusion 221 is inserted into the second connecting hole 1211.

[0099] The moving touch assembly 200 has a first connecting protrusion 211 and a second connecting protrusion 221 on opposite sides. The first connecting protrusion 211 is inserted into the first connecting hole 1111 on the first connector 110, and the second connecting protrusion 221 is inserted into the second connecting hole 1211 on the second connector 120, so as to realize the connection between the moving touch assembly 200 and the mounting bracket 100. The implementation cost is low and the fixing effect is reliable.

[0100] As a supplement, after the moving contact assembly 200 is assembled with the mounting bracket 100, the first abutting part 112 and the second abutting part 122 abut against the inner side wall of the cover 300 to prevent the first connecting protrusion 211 and the second connecting protrusion 221 from falling out of the first connecting hole 1111 and the second connecting hole 1211 respectively, thus ensuring the reliability of the relay.

[0101] As an embodiment that can be implemented simultaneously with the above embodiments, the first mating part 210 is provided with a third connecting hole, the second mating part 220 is provided with a fourth connecting hole, the first connecting part 111 is provided with a third connecting protrusion, the second connecting part 121 is provided with a fourth connecting protrusion, the third connecting protrusion is inserted into the third connecting hole, and the fourth connecting protrusion is inserted into the fourth connecting hole.

[0102] The movable touch component 200 is provided with a third connection hole and a fourth connection hole on opposite sides. The third connection protrusion on the first connector 110 is inserted into the third connection hole on one side of the movable touch component 200, and the fourth connection protrusion on the second connector 120 is inserted into the fourth connection hole on the other side of the movable touch component 200, so as to realize the connection between the movable touch component 200 and the mounting bracket 100. The implementation cost is low and the fixing effect is reliable.

[0103] As a further explanation, one side of the moving contact assembly 200 may be provided with a first connecting protrusion 211 and a third connecting hole, and the other side of the moving contact assembly 200 may be provided with a second connecting protrusion 221 and a fourth connecting hole. Correspondingly, the first connecting portion 111 may be provided with a first connecting hole 1111 and a third connecting protrusion, and the second connecting portion 121 may be provided with a second connecting hole 1211 and a fourth connecting protrusion to ensure assembly reliability.

[0104] Understandably, one side of the moving contact component 200 may be provided with either the first connecting protrusion 211 or the third connecting hole, and the other side of the moving contact component 200 may be provided with either the second connecting protrusion 221 or the fourth connecting hole. Correspondingly, the first connecting portion 111 may be provided with either the first connecting hole 1111 or the third connecting protrusion, and the second connecting portion 121 may be provided with either the second connecting hole 1211 or the fourth connecting protrusion.

[0105] exist Figure 5 In the embodiment shown, the first connecting protrusion 211 includes a first hook, the second connecting protrusion 221 includes a second hook, the first connecting hole 1111 and the second connecting hole 1211 are both through holes, the first hook passes through the first connecting hole 1111 and is hooked to the hole wall of the first connecting hole 1111, and the second hook passes through the second connecting hole 1211 and is hooked to the hole wall of the second connecting hole 1211.

[0106] Please see Figures 2 to 6 In one embodiment, the moving contact assembly 200 includes a first moving contact 231, a first mounting base 232, and a first elastic member 233. The relay also includes a first stationary contact assembly 410, which is located on the side of the mounting bracket 100 facing the opening 141. The first moving contact 231 is disposed on the first mounting base 232. A first mating part 210 is provided on one side of the first mounting base 232, and a second mating part 220 is provided on the other side of the first mounting base 232. One end of the first elastic member 233 is disposed on the mounting member 130, and the other end of the first elastic member 233 is disposed on the first mounting base 232.

[0107] When the first connector 110 and the second connector 120 move away from the moving contact assembly 200, the first abutting part 112 and the second abutting part 122 can abut against the inner wall of the cover 300, preventing the first connector 110 and the second connector 120 from moving further and causing the first mounting base 232 to detach from the mounting groove 142, thereby improving the reliability of the relay.

[0108] Furthermore, the end of the push rod 510 away from the electromagnet unit 520 is connected to the mounting piece 130.

[0109] Optionally, the first elastic element 233 can be a flexible, bent sheet or a spring, etc., without specific limitations.

[0110] In one embodiment, the first mounting base 232 includes a first magnetic conductor, and the first stationary contact assembly 410 includes a second magnetic conductor. The first magnetic conductor is used to cooperate with the second magnetic conductor to form an anti-short-circuit ring structure. When energized, the first magnetic conductor and the second magnetic conductor can be magnetized and attract each other, thereby preventing the first moving contact 231 and the stationary contact of the first stationary contact assembly 410 from springing apart. By connecting the first magnetic conductor to the first connecting part 111, the utilization efficiency of the structure can be improved.

[0111] Please see Figures 9 to 10 As an alternative embodiment to the above embodiment, the moving contact assembly 200 includes a second moving contact 241, a second mounting base 242, and a second elastic member 243. The relay also includes a second stationary contact assembly 420, which is located on the side of the mounting bracket 100 opposite to the direction of the opening 141. A first mating part 210 is provided on one side of the second mounting base 242, and a second mating part 220 is provided on the other side of the second mounting base 242. One end of the second elastic member 243 is located on the side of the second mounting base 242 opposite to the direction of the opening 141, and the other end of the second elastic member 243 is connected to the second moving contact 241.

[0112] When the first connector 110 and the second connector 120 move away from the moving contact assembly 200, the first abutting part 112 and the second abutting part 122 can abut against the inner wall of the cover 300, preventing the first connector 110 and the second connector 120 from moving further and causing the second mounting base 242 to detach from the mounting groove 142, thereby improving the reliability of the relay.

[0113] Furthermore, the end of the push rod 510 away from the electromagnet unit 520 is connected to the second mounting base 242.

[0114] Optionally, the second elastic element 243 can be a flexible, bent sheet or a spring, etc., without specific limitations.

[0115] Additionally, in the two embodiments described above, in one embodiment, the opening 141 of the mounting bracket 100 is oriented towards the stationary contact assembly (i.e., the first stationary contact assembly 410 in the first embodiment), while in the other embodiment, the opening 141 of the mounting bracket 100 is oriented away from the stationary contact assembly (i.e., the second stationary contact assembly 420 in the second embodiment). Regardless of the orientation of the opening 141, the first abutting portion 112 and the second abutting portion 122 can abut against the inner wall of the cover 300 as the size of the opening 141 gradually increases, thereby preventing the size of the opening 141 from further increasing and causing the moving contact assembly 200 to detach from the mounting groove 142.

[0116] 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.

[0117] The above embodiments merely illustrate 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.
