Description

Technical Field

[0001] This utility model relates to the field of electronic control device technology, and more specifically, to a connection component and 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), and is commonly used in automatic control circuits. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] In a relay, the armature assembly is connected to the contact assembly via a pusher. Specifically, as the armature assembly rotates around its axis, the pusher moves the moving contact to contact or disengage from the stationary contact.

[0004] In existing technologies, push-type clips typically have a through hole extending along the thickness direction. The armature assembly engages with this through hole via a locking block located at its movable end, thus securing the push-type clip to the movable end of the armature assembly. It is worth noting that when assembling the push-type clip and armature assembly in these technologies, the movable end of the armature assembly needs to be moved into place, and significant pressure needs to be applied along the thickness direction of the push-type clip to effectively engage the clip and armature assembly, making assembly quite difficult. Furthermore, during the application of pressure to the push-type clip, the armature assembly is highly susceptible to movement due to the force, preventing the two from being properly assembled.

[0005] Therefore, there is an urgent need to provide a connection component that can reduce assembly difficulty. Utility Model Content

Detailed Implementation

[0049] 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.

[0050] This application provides a connecting component. The connecting component includes an armature bracket and a pusher. Figure 1 The diagram shown is a three-dimensional structural schematic of the connecting component provided in an embodiment of the present invention;

[0051] Figure 2 What is shown is Figure 1 A three-dimensional structural diagram of the armature support; Figure 3 What is shown is Figure 1 A schematic diagram of the three-dimensional structure of the push card.

[0052] Among them, such as Figure 1 and Figure 2As shown, the armature bracket 100 includes a body portion 110 and a connecting portion 120. The body portion 110 is pivotally connected to a mounting base inside the relay, and the connecting portion 120 is connected to the movable end of the body portion 110. It can be understood that since the body portion 110 is pivotally connected to the mounting base, there exists a rotation axis. Figure 1 The rotation axis of the main body 110 is shown in dashed line, and the main body 110 can rotate around this rotation axis.

[0053] like Figure 1 and Figure 3 As shown, the push card 200 includes a first portion 210 and a second portion 220 that are interconnected. It should be understood that... Figure 3 The first part 210 and the second part 220 are schematically separated by a dashed line. Of course, the position of the division between the first part 210 and the second part 220 is not limited to this. Figure 3 As shown in the diagram, the specific details will not be repeated. The first part 210 is used to connect the contact components inside the relay, and the second part 220 is located on one side of the first part 210 in the first direction X; the second part 220 is provided with a plug groove 221, and the opening of the plug groove 221 is located on one side of the second part 220 in the second direction Y; the second direction Y is perpendicular to the first direction X and parallel to the rotation axis of the body part 110.

[0054] Figure 4 What is shown is Figure 2 Enlarged view of point B in the middle; Figure 5 What is shown is Figure 1 An enlarged diagram of point A in the middle; please refer to... Figure 4 and Figure 5 Continue to refer to Figures 1 to 3 As shown in the structure, at least a portion of one end of the connecting part 120 in the second direction Y is inserted into the insertion slot 221 from the slot opening, and the other end of the connecting part 120 in the second direction Y is provided with a limiting slot 121; the slot opening of the limiting slot 121 is arranged opposite to the slot opening of the insertion slot 221, and at least a portion of the push card 200 is located in the limiting slot 121. The limiting slot 121 is at least used to limit the maximum displacement of the push card 200 in the third direction Z, which is perpendicular to the first direction X and the second direction Y. It can be understood that, in order to more clearly understand the connecting component 10 provided in the embodiments of this application, X is used to identify the first direction, Y to identify the second direction, and Z to identify the third direction in the embodiments of this application.

[0055] Figure 6 The diagram shown is a structural schematic of the connecting component 10 provided in this embodiment of the present invention during assembly; please refer to... Figures 1 to 5 The structural reference shown Figure 6When assembling the connecting assembly 10 provided in this embodiment, the armature bracket 100 is moved along a second direction Y parallel to the rotation axis to the corresponding position of the push card 200 to complete the assembly. Specifically, the armature bracket 100 and the push card 200 can be controlled to move relative to each other in a branch direction Y1 of the second direction Y, so that the connecting part 120 in the armature bracket 100 is inserted into the insertion slot 221 of the push card 200. At the same time, during the movement of the armature bracket 100 relative to the push card 200 along the branch direction Y1, the push card 200 is inserted into the limiting slot 121 from the opening of the limiting slot 121 of the armature bracket 100.

[0056] It should be noted that the connecting component 10 provided in this application embodiment sets the connection direction between the armature bracket 100 and the push card 200 in the direction parallel to the rotation axis of the inner body portion 110 of the armature bracket 100. This simplifies the assembly steps, allowing the assembly of the armature bracket 100 with the mounting base 40 and the armature bracket 100 with the push card 200 to be completed simultaneously, thereby reducing assembly difficulty and improving assembly efficiency. Furthermore, the connecting component 10 provided in this application embodiment sets the slot of the insertion groove 221 of the push card 200 and the slot of the limiting groove 121 of the armature bracket 100 to be opposite each other in the second direction Y. Therefore, when assembling the armature bracket 100 relative to the push card 200, the connecting portion 120 of the armature bracket 100 can be smoothly inserted into the insertion groove 221, and simultaneously, the second portion 220 of the push card 200 can be smoothly placed into the limiting groove 121, further improving assembly efficiency.

[0057] It is worth noting that you should continue to refer to [the relevant information]. Figure 6 As shown in the embodiment of this application, the armature bracket 100 is used to assemble the armature 20. The pusher 200 connects the armature bracket 100 and the contact assembly 30, so that the main contacts in the contact assembly 30 can make or disengage during the rotation of the armature 20 around the rotation axis. Specifically, after the armature bracket 100 is assembled to the mounting base 40, the armature bracket 100 can rotate around the rotation axis. During the rotation of the armature bracket 100, the connecting part 120 of the armature bracket 100 acts on the pusher 200, so that the pusher 200 moves in the first direction X, and drives the main contacts in the contact assembly 30 to make or disengage.

[0058] It is understandable that, during the movement of the armature bracket 100 driving the push card 200, the rotational movement of the armature bracket 100 will eventually switch to the linear movement of the push card 200. Therefore, there is a tendency for the push card 200 to disengage along the third direction Z at the connection position between the push card 200 and the armature bracket 100. Accordingly, the connecting component 10 provided in this application embodiment has at least a portion of one end of the connecting part 120 in the second direction Y inserted into the insertion groove 221 from the slot, thereby limiting the displacement of the connecting part 120 in the third direction Z through the insertion groove 221; on the other hand, the other end of the connecting part 120 in the second direction Y is provided with a limiting groove 121, and at least a portion of the push card 200 is located in the limiting groove 121, so as to limit the maximum displacement of the push card 200 in the third direction Z through the limiting groove 121, and prevent the push card 200 from disengaging from the armature bracket 100 at the connection position. Therefore, the connection component 10 provided in this application embodiment can ensure the reliability of the connection between the armature bracket 100 and the push card 200, thereby ensuring the structural performance of the relay and extending its service life.

[0059] It is worth noting that when the limiting groove 121 is formed in the connecting part 120 of the armature bracket 100, there are multiple possibilities for the structure of the limiting groove 121.

[0060] In one embodiment, please refer to... Figure 2 and Figure 4 The structure shown includes a first region, a second region, and a third region in the opening of the limiting groove 121. The first region is located on the side of the connecting portion 120 facing the insertion groove 221 in the second direction Y. The second and third regions are positioned on both sides of the connecting portion 120 along the first direction X and communicate with the first region. At least a portion of the push card 200 extends into the limiting groove 121 from the first region of the opening. It should be understood that... Figure 4 The first, second, and third regions are schematically separated by dashed lines.

[0061] It should be noted that, in this embodiment of the application, the connecting part 120 forms a U-shaped structure at the position of the limiting groove 121, and the U-shaped structure frames at least a portion of the second part 220 of the push card 200 in the third direction Z, limiting the maximum displacement of the push card 200 in the third direction Z, preventing the push card 200 from dislodging from the armature bracket 100 at the connection position, thereby ensuring the reliability of the connection relationship between the armature bracket 100 and the push card 200, ensuring the structural performance of the relay, and extending its service life.

[0062] In a specific embodiment, such as Figure 4As shown, the connecting part 120 includes a columnar extension section 122, the extension direction of which is parallel to the second direction Y, and a hook structure 123 is connected to one end of the columnar extension section 122 facing away from the insertion groove 221 in the second direction Y, so that the hook structure 123 cooperates with the columnar extension section 122 to form a limiting groove 121.

[0063] Please continue to refer to this. Figure 4 The structure shown allows for the following: for the end of the columnar extension 122 used for insertion into the insertion slot 221 in the second direction Y, a guide slope can be provided on the insertion side of the columnar extension 122 to reduce the difficulty of inserting the connecting part 120 into the insertion slot 221. Alternatively, the columnar extension 122 can be cut on the insertion side; specifically, the columnar extension 122 can be cut into a flat surface on the side of the columnar extension 122 facing away from the hook structure 123 in the third direction Z to improve the limiting effect of the insertion slot 221 on the connecting part 120 in the third direction Z.

[0064] In another embodiment, the opening of the limiting groove 121 may be configured to include only the first region. In other words, the connecting portion 120 has the opening of the limiting groove 121 on one side in the second direction Y. It should be noted that the limiting groove 121 in this embodiment can limit not only the maximum displacement of the push card 200 in the third direction Z, but also the maximum displacement of the push card 200 in the first direction X. Of course, the structure of the push card 200 in this embodiment will be relatively... Figure 3 There are changes to ensure that at least a portion of the second part 220 of the push card 200 can be placed into the limiting groove 121 in this embodiment, which will not be described in detail here.

[0065] In one embodiment, such as Figure 1 As shown, the gap between the groove walls of the limiting groove 121 in the third direction Z is greater than the thickness of the portion of the push card 200 located in the limiting groove 121 in the third direction Z, so as to reserve a gap between the push card 200 and the armature bracket 100 along the third direction Z, to avoid interference and jamming between the push card 200 and the armature bracket 100, and to ensure the structural performance of the relay.

[0066] In one embodiment, please combine Figures 2 to 4 refer to Figure 5 The structure shown includes a limiting groove 121 whose walls comprise a first wall surface 1211 and a second wall surface 1212 disposed opposite each other in the third direction Z. Along the third direction Z, the first wall surface 1211 contacts the second portion 220 of the push card 200, and the second wall surface 1212 has a first gap a with the second portion 220 of the push card 200. It is understood that, due to viewing angle, the first wall surface 1211... Figure 5 Not shown in the image.

[0067] It is worth noting that during the movement of the push card 200, the longer the stroke of the push card 200 in the first direction X, the greater the rotation angle of the armature bracket 100. This results in an increase in the movement distance of the armature bracket 100 in the third direction Z. Therefore, to avoid interference and jamming between the push card 200 and the armature 20, in one embodiment, the following can be configured: Figure 5 The size of the first gap 'a' shown is positively correlated with the length of the travel distance of the push card 200 in the first direction X, in order to ensure the structural performance of the relay. For example, the longer the travel distance of the push card 200 in the first direction X, the larger the first gap 'a'.

[0068] In one embodiment, such as Figure 4 As shown, in a plane perpendicular to the second direction Y, the cross-section of the first wall 1211 is an arc-shaped line convex to the second wall 1212, and the cross-section of the second wall 1212 is an arc-shaped line convex to the first wall 1211.

[0069] It should be noted that the structural configuration in this embodiment can ensure that the contact position between the armature bracket 100 and the push card 200 can move smoothly during the rotation of the armature bracket 100 relative to the push card 200, avoiding interference and jamming between the push card 200 and the armature 20, and ensuring the structural performance of the relay.

[0070] It is worth noting that the bottom of the insertion slot 221 in the third direction Z can limit the maximum displacement of the push card 200 and the armature bracket 100 in the third direction Z, ensuring that the two are assembled in place. Figure 7 The diagram shown is a three-dimensional structural schematic of the connecting component 10 provided in an embodiment of the present invention from another angle; Figure 8 What is shown is Figure 7 A magnified view of point D. In one embodiment, as shown... Figure 8 As shown in the structure, after the push card 200 and the armature bracket 100 are assembled, the bottom of the limiting groove 121 in the second direction Y has a second gap b between it and the push card 200. The second gap b is greater than 0.3mm, so as to reserve a gap between the push card 200 and the armature bracket 100 along the second direction Y, so as to avoid interference and jamming between the push card 200 and the armature bracket 100, and to ensure the structural performance of the relay.

[0071] It is worth noting that the value of the second gap b should not be too large, so as to avoid the connection component 10 occupying too much space in the second direction Y, which would affect the miniaturization design of the relay.

[0072] Figure 9 What is shown is Figure 3 A magnified diagram of point C. Please refer to... Figure 3 refer to Figure 9In one embodiment of the structure shown, along the second direction Y, the second part 220 of the push card 200 is provided with a limiting recess 222 on the side opposite to the insertion slot 221, and the limiting recess 222 is provided through the third direction Z; at least a portion of the limiting groove 121 is located in the limiting recess 222, and the limiting recess 222 is used to limit the maximum displacement of the connecting part 120 in the first direction X.

[0073] It should be noted that in this embodiment, the push card 200 in the limiting recess 222 is also equivalent to a U-shaped structure. This U-shaped structure frames the connecting part 120 within it, limiting the maximum displacement of the connecting part 120 in the first direction X. Specifically, in conjunction with the design of the limiting groove 121 of the connecting part 120, in this embodiment, the U-shaped structure of the push card 200 in the limiting recess 222 and the opening of the U-shaped structure formed by the connecting part 120 in the limiting groove 121 are arranged opposite to each other in the second direction Y, and after being flipped at a certain angle, they are interlocked through the opening of the U-shaped structure.

[0074] Of course, in order to avoid interference and jamming between the push card 200 and the armature 20, in one embodiment, the portion of the connecting portion 120 placed in the limiting recess 222 has a gap with the inner wall of the limiting recess 222 in the first direction X.

[0075] In one embodiment, please refer to Figure 8 In the structure shown, along the second direction Y, the second portion 220 of the push card 200 has a thinned region near the limiting recess 222, and at least a portion of the second portion 220 with the thinned region is placed within the limiting groove 121. It can be understood that the thickness of the connecting portion 120 within the thinned region in the third direction Z is less than the thickness of other regions.

[0076] It should be noted that the structural configuration in this embodiment can, on the one hand, improve the integration of each structural component, ensure effective connection between the push card 200 and the armature bracket 100, and prevent interference and jamming between the two during movement. On the other hand, it can ensure that the thickness of the push card 200 in other parts is sufficient, thus ensuring the structural strength of the push card 200, improving the service life of the push card 200, and ensuring the structural reliability of the relay.

[0077] In one embodiment, please refer to Figure 9 As shown in the structure, the wall surface of the limiting recess 222 near the opening in the second direction Y is an inclined surface; the inclined surface includes a first inclined surface 2221 and a second inclined surface 2222 disposed opposite to each other in the first direction X, pointing from the bottom of the limiting recess 222 towards the opening direction of the limiting recess 222, the distance between the first inclined surface 2221 and the second inclined surface 2222 gradually increases, so as to facilitate the insertion of the connecting part 120 into the limiting recess 222, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0078] It is worth noting that the bottom of the limiting recess 222 in the second direction Y has a smaller thickness, so as to ensure that the push card 200 and the armature bracket 100 are effectively connected and to avoid interference and jamming between the two during movement.

[0079] In one specific embodiment Figure 4 The columnar extension 122 forms the first wall surface 1211. Since the cross-section of the first wall surface 1211 is an arc-shaped line convex toward the second wall surface 1212 in a plane perpendicular to the second direction Y, therefore, as Figure 9 As shown, the surface of the push card 200 that is used to contact the first wall surface 1211 is provided with an arc-shaped adjustment surface 223, and the arc-shaped adjustment surface 223 is an arc-shaped line convex to the side away from the first wall surface 1211 in a plane perpendicular to the second direction Y.

[0080] In one embodiment, such as Figure 1 and Figure 2 As shown, the armature bracket 100 also includes a blocking part 130, which is connected to the main body 110. The blocking part 130 is located on the side of the connecting part 120 away from the push card 200 in the first direction X and is spaced apart from the connecting part 120. Along the first direction X, part of the push card 200 is located in the gap between the connecting part 120 and the blocking part 130, and the remaining part of the push card 200 is located on the side of the connecting part 120 away from the blocking part 130.

[0081] It should be noted that, in this embodiment, the blocking part 130 can increase the creepage distance and air gap between the internal structural components of the contact assembly 30 and the armature 20 installed on the armature bracket 100, so as to improve the safety performance of the relay.

[0082] Of course, the push card 200 also has structures such as recesses, through holes or even protrusions for connecting with the contact assembly 30, which will not be described in detail here.

[0083] Furthermore, it is worth noting that a hollow area can be formed in the push card 200 to reduce the weight of the structural components. Alternatively, the hollow area can be set in the cavity wall of the second part 220 forming the insertion groove 221, so as to avoid the portion of the first connection part 120 located in the insertion groove 221 when the connection part 120 of the armature bracket 100 tends to move relative to the push card 200 in the third direction Z.

[0084] In one embodiment, such as Figure 2As shown, the armature bracket 100 also includes a rotating support portion 140 for pivotal connection with the mounting base 40. The rotating support portion 140 is connected to the side of the body portion 110 in the second direction Y and extends from the body portion 110 in a direction away from the body portion 110. Notably, this rotating support portion 140 forms the rotation axis of the armature bracket 100. Specifically, this rotating support portion 140 can serve as a pivot for assembly relative to the mounting base within the relay, and rotates relative to the mounting base about the rotation axis during use.

[0085] Figure 10 What is shown is Figure 2 A partial cross-sectional view of the structure at plane M. Plane M is parallel to the second direction Y. In one embodiment, please refer to... Figure 2 refer to Figure 10 The structure shown has a countersunk hole 141 on the side of the rotating support 140 away from the main body 110 along the second direction Y.

[0086] It should be noted that in this embodiment of the application, the rotating support part 140 is partially hollowed out to form a countersunk hole 141 because the armature bracket 100 is generally a plastic part. If the rotating support part 140 is solid, it is easy to deform during the molding process.

[0087] In one embodiment, such as Figure 10 As shown, the bottom wall of the countersunk hole 141 in the second direction Y is located on the side opposite to the body part 110 at the connection surface between the rotating support part 140 and the body part 110. That is, there is a height difference between the inner and outer stepped surfaces of the rotating support part 140 in the second direction Y, which can improve the strength of the armature bracket 100, extend the service life of the armature bracket 100, and improve the structural reliability of the relay.

[0088] In one embodiment, please refer to... Figure 10 As shown in the structure, the rotating support part 140 and the main body part 110 are connected by an arc-shaped surface or a slope at the root of the connection, which avoids the rotating support part 140 and the main body part 110 forming a right angle at the root of the connection. This can reduce the possibility of the rotating support part 140 and the main body part 110 tearing at the root, thereby extending the service life of the armature bracket 100 and improving the structural reliability of the relay.

[0089] This application also provides a relay. The relay includes a connection component 10 as provided in any of the above technical solutions.

[0090] It should be noted that in the relay provided in this application embodiment, the connection component 10 sets the connection direction between the armature bracket 100 and the push card 200 in the direction parallel to the rotation axis of the inner body portion 110 of the armature bracket 100. This simplifies the assembly steps, allowing the assembly of the armature bracket 100 with the mounting base 40 and the assembly of the armature bracket 100 with the push card 200 to be completed simultaneously, thereby reducing assembly difficulty and improving assembly efficiency. Moreover, the connection component 10 provided in this application embodiment is configured such that the slot of the insertion groove 221 of the push card 200 and the slot of the limiting groove 121 of the armature bracket 100 are opposite in the second direction Y. Therefore, when assembling the armature bracket 100 relative to the push card 200, the connecting portion 120 of the armature bracket 100 can be smoothly inserted into the insertion groove 221, and at the same time, the second portion 220 of the push card 200 can be smoothly placed into the limiting groove 121, further improving assembly efficiency.

[0091] Meanwhile, in the relay provided in this application embodiment, the connecting component 10 has at least a portion of one end of the connecting part 120 in the second direction Y inserted into the insertion slot 221 through the slot, thereby limiting the displacement of the connecting part 120 in the third direction Z through the insertion slot 221; on the other hand, the other end of the connecting part 120 in the second direction Y is provided with a limiting slot 121, and at least a portion of the push card 200 is located in the limiting slot 121, so as to limit the maximum displacement of the push card 200 in the third direction Z through the limiting slot 121, thereby preventing the push card 200 from disengaging from the armature bracket 100 at the connection position.

[0092] Accordingly, when the reliability of the connection between the armature bracket 100 and the push card 200 is improved, the structural performance of the relay provided in this application embodiment can be guaranteed, and its service life can also be extended.

[0093] Figure 12 The diagram shown is a structural schematic of the relay provided in an embodiment of this utility model; Figure 13 What is shown is Figure 12 Sectional view at midplane N; Figure 14 What is shown is Figure 13 An enlarged schematic diagram at point E. Plane N is perpendicular to the first direction X. Please refer to... Figure 6 refer to Figures 12 to 14 As shown in the embodiment, the relay further includes a mounting base 40, which has a first chamber and a second chamber, with a connection channel between the second chamber and the first chamber. The push card 200 in the connection assembly 10 is movably mounted in the mounting base 40 along the first direction X, and at least a portion of the push card 200 is located in the connection channel. Figure 13 As shown, along the second direction Y, the push card 200 has a third gap with the cavity wall of the connecting channel; as Figure 14The second part 220 of the push card 200 shown is inserted into the mounting groove of the armature bracket 100 in the connecting assembly 10 along the second direction Y, and the depth c is greater than that of the groove. Figure 13 The third gap in the middle.

[0094] It should be noted that after the connecting component 10 is assembled to the mounting base 40, the internal cavity wall of the mounting base 40 can limit the connection position of the push card 200 and the armature bracket 100 in the second direction Y, preventing the push card 200 and the armature bracket 100 from separating in the opposite direction of assembly. Accordingly, in this embodiment, the second part 220 of the push card 200 is inserted into the mounting groove of the armature bracket 100 in the connecting component 10 in the second direction Y, with the depth c being greater than the third gap. This effectively limits the connecting component 10 through the internal cavity wall of the mounting base 40, preventing the limiting groove 121 in the armature bracket 100 from failing to limit the push card 200 in the third direction Z. This ensures the reliability of the connection between the armature bracket 100 and the push card 200, protects the structural performance of the relay, and extends its service life.

[0095] Figure 15 The diagram shown is an exploded view of a relay provided in an embodiment of this application. Figure 15 As shown, when assembling the relay provided in this application embodiment, the contact component 30 can be assembled from the first opening along the third direction Z into the first cavity of the mounting base 40, and during this process, the push card 200 is assembled synchronously with the contact component 30; then, the push card 200 connected to the contact component 30 is pulled along the first direction X, so that the push card 200 moves away from the first cavity in the first direction X; then, the armature assembly formed by the armature bracket 100 and the armature 20 can be assembled from the opening of the second cavity into the second cavity of the mounting base 40 along a branch direction Y1 of the second direction Y.

[0096] It is worth noting that during the assembly of the armature assembly formed by the armature bracket 100 and the armature 20 along the second direction Y, the connecting part 120 of the armature bracket 100 is simultaneously inserted into the insertion slot 221, and at least part of the second part 220 of the push card 200 is placed into the limiting slot 121 of the connecting part 120, so that the armature bracket 100 and the push card 200 are connected.

[0097] Subsequently, the auxiliary connecting plate 50 can be assembled to the mounting base 40, such that the auxiliary connecting plate 50 blocks at least a portion of the opening of the second chamber. It is noteworthy that the side wall of the second chamber opposite the opening in the second direction Y provides a fixed support point for the armature bracket 100, while the auxiliary connecting plate 50 provides another fixed support point for the armature bracket 100, allowing the armature bracket 100 to rotate relative to the mounting base 40 about its rotation axis by rotating the support portion 140.

[0098] For example, please continue to refer to Figure 15 The structure shown includes a stationary contact lead-out end 301, a movable contact lead-out end 302, and a movable contact 303. The movable contact lead-out end 302 and the stationary contact lead-out end 301 are spaced apart in the first direction X and respectively pass through a mounting base 40. One end of the movable contact 303 is connected to the end of the movable contact lead-out end 302 in the third direction Z, away from the bottom of the first chamber. The other end of the movable contact 303 is used to contact or disengage from a stationary contact point located on the stationary contact lead-out end 301. The movable contact 303 may be provided with a movable contact point to contact the main contact point with the stationary contact point.

[0099] It is worth noting that the push card 200 is connected to the other end of the "moving contact 303" so that when the push card 200 moves along the first direction X, it drives the other end of the moving contact 303 to contact or disengage from the stationary contact point provided at the stationary contact lead-out end 301.

[0100] It is understandable that the specific structure of contact component 30 is not limited to... Figure 15 As shown, other settings can be made according to needs, which will not be elaborated here.

[0101] In one embodiment, the third gap includes the gap between the push card 200 and the cavity wall of each side connection channel in the second direction Y. Exemplarily, the third gap is... Figure 14 The sum of the dimensions of gaps L1 and L2 shown.

[0102] It is understandable that, considering factors such as assembly errors, the gap between the push card 200 and the cavity wall of each side connection channel in the second direction Y can be the same or different.
