Detailed implementation manners

[0044] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] During the production process of a circuit board of an electronic device, in order to ensure the stability of signal connection, it is necessary to perform an external radio frequency signal detection on an electrical connector. In the prior art, a radio frequency detection switch is usually used for this detection. Exemplarily, the radio frequency detection switch includes a first terminal and a second terminal, and the first terminal and the second terminal can be in contact with each other to maintain signal connection. When performing an external radio frequency signal detection, the second terminal is pressed by a detection probe, so that the second terminal is separated from the first terminal and the signal connection is disconnected, and thus the signal connection between the detection probe and the second terminal is conducted. In the prior art, due to the poor fixation of the first terminal, when the second terminal is pressed by the detection probe, the contact part of the first terminal can be displaced accordingly, resulting in the first terminal and the second terminal being unable to be separated smoothly, which affects the detection progress.

[0046] To solve the above technical problems, the present disclosure provides a switch structure, a functional module, and an electronic device. The switch structure includes a first terminal, a second terminal, and an insulating part. The first contact part of the first terminal for contacting the second terminal is partially embedded in the insulating part, and the insulating part effectively fixes the first contact part, preventing the first contact part from being displaced due to reasons such as shaking and deformation, so that the first terminal and the second terminal can stably maintain a separated state during the detection process. Designed in this way, the stability of the switch structure is improved, ensuring that the detection probe can stably conduct the signal to the detection instrument during the detection process.

[0047] One exemplary embodiment of the present disclosure provides a switch structure, which may be a radio frequency switch structure, for example. As Figures 1 to 5 shown, the switch structure includes an insulating portion, a first terminal 1, and a second terminal 2. The first terminal 1 includes a first contact portion 11 for contacting the second terminal 2. The second terminal 2 includes a second contact portion 21 for contacting the first terminal 1. The first contact portion 11 and the second contact portion 21 can contact each other to connect the signal connection between the first terminal 1 and the second terminal 2, and the first contact portion 11 and the second contact portion 21 can also be separated to disconnect the signal connection between the first terminal 1 and the second terminal 2. The second terminal 2 is connected to the insulating portion, and the connection method may be a detachable connection such as bonding or abutting, and is not limited thereto.

[0048] Part of the structure in the first contact portion 11 is embedded in the insulating portion, so that the first contact portion 11 is fixed on the insulating portion, realizing the limitation and shaping of the first contact portion 11. The second contact portion 21 can contact and separate from the portion of the first contact portion 11 exposed outside the insulating portion. During the detection process, when the second terminal 2 is pressed by the detection probe and the second contact portion 21 moves away from the first contact portion 11, the first contact portion 11 can stably stay in the original position and maintain the original shape, avoiding the displacement of the first contact portion 11 and continuing to contact the second contact portion 21. Among them, the portion of the first contact portion 11 embedded in the insulating portion can be close to or connected to the portion in contact with the second contact portion 21 to further improve the fixing effect of the insulating portion on the first contact portion 11.

[0049] With such a setting method, the first contact portion 1 is effectively fixed, preventing the first contact portion from being displaced due to reasons such as shaking and deformation, enabling the first terminal and the second terminal to stably maintain a separated state during the detection process, improving the stability of the switch structure, and ensuring that the detection probe can stably conduct signals to the detection instrument during the detection process.

[0050] In one embodiment, as Figure 3 and Figure 5 shown, the first contact portion 11 includes an embedding portion 111 and at least one protruding portion 112. The embedding portion 111 is embedded in the insulating portion, and the protruding portion 112 is provided on the embedding portion 111 and exposed outside the insulating portion. The protruding portion 112 faces the second contact portion 21, and the second contact portion 21 can contact and separate from the protruding portion 112, that is, the first contact portion 11 realizes contact and separation from the second contact portion 21 through the protruding portion 112.

[0051] The convex portion 112 can be provided with one or more. When multiple convex portions 112 are provided, the second contact portion 21 can contact and separate from the multiple convex portions 112. When there is a convex portion 112 that cannot be used due to fouling or other reasons, the first contact portion 11 can still achieve signal communication with the second contact portion 21 through other convex portions 112, improving the signal connection stability of the switch structure. In one example, as Figure 5 shown, two convex portions 112 are provided, which can minimize the structural size of the switch structure while ensuring signal connection stability.

[0052] Refer to Figure 3 and Figure 5 , in one embodiment, the embedding portion 111 includes opposite first surface 1111 and second surface 1112. The embedding portion 111 can be, for example, an embedding plate. Among them, the first surface 1111 is located on the surface of the embedding plate facing away from the second contact portion 21, and the second surface 1112 is located on the surface of the embedding plate facing the second contact portion 21. Part of the first surface 1111 is recessed towards the second contact portion 21, and the position of the second surface 1112 corresponding to the recessed portion of the first surface 1111 protrudes towards the second contact portion 21, thereby forming the convex portion 112. With such a setting method, on the one hand, the processing difficulty of the convex portion 112 is reduced, facilitating mass production of the switch structure. On the other hand, the recessed portion of the first surface 1111 can also be embedded in the insulating portion, and the recessed structure can increase the contact area between the embedding portion 111 and the insulating portion, improving the stability of the switch structure. In some other embodiments, the shape of the embedding portion 111 can be designed according to actual situations. For example, it can be a cylinder or a hemisphere, etc. The convex portion 112 includes, but is not limited to, cylindrical protrusions, hemispherical protrusions, etc. provided on the surface of the embedding portion 111, and this is not limited.

[0053] When there is a foreign object between the contact positions of the first contact portion 11 and the second contact portion 21, or between the detection probe and the second contact portion 21, the foreign object will form a barrier at the contact point, affecting signal conduction. Therefore, a leakage space is provided in the switch structure to allow the foreign object to slide out from the second contact portion 21. Refer to Figure 5 , in some embodiments, multiple convex portions 211 are provided, and there is a certain distance between adjacent convex portions 211, thereby forming a leakage space. As an example, as Figures 2 to 5As shown, when there is a foreign object in the second contact portion 21 or a portion of the second terminal 2 connected to the second contact portion 21, as the detection probe presses the second terminal 2, the second contact portion 21 moves away from the first contact portion 11 and causes a portion of the structure in the second terminal 2 to tilt downward. As a result, the foreign object slides to the convex portion 112 and can slide out from the material leakage space and leave the switch structure. With such a setting form, not only can the self-cleaning of foreign objects on the second terminal 2 be achieved, but also the accumulation of foreign objects at the convex portion 112 can be avoided, ensuring the signal connection stability of the switch structure. In addition, the material leakage space enables foreign objects to leave the switch structure in a timely manner, preventing damage such as fouling or corrosion of the switch structure by foreign objects, and effectively extending the service life of the switch structure.

[0054] The distance between adjacent convex portions 112 directly affects the size of the material leakage space. If the distance between adjacent convex portions 112 is too large, the first contact portion 11 will occupy more installation space, compressing the design space of other components and being disadvantageous for controlling the overall size of the switch structure. If the distance between adjacent convex portions 112 is too small, the material leakage space cannot allow foreign objects to pass through, resulting in the accumulation of foreign objects at the convex portion 211. Among them, the distance between adjacent convex portions 112 can refer to the minimum vertical distance between the opposite faces of adjacent convex portions 112, or the vertical distance between the central axes of adjacent convex portions 112. In some embodiments, as Figure 5 shown, the vertical distance between the central axes of adjacent convex portions 112 is less than or equal to 0.15 mm, and this size design can save space for the switch structure as much as possible. In some embodiments, as Figure 5 shown, the minimum vertical distance between the opposite faces of adjacent convex portions 112 is greater than or equal to 0.08 mm. Since the sizes of the vast majority of foreign objects in the usage environment of the switch structure are less than 0.08 mm, this size design can effectively ensure that foreign objects smoothly slide out from the material leakage space. In this embodiment, as Figure 5 shown, the vertical distance between the central axes of adjacent convex portions 112 is less than or equal to 0.15 mm, and the minimum vertical distance between the opposite faces of adjacent convex portions 112 is greater than or equal to 0.08 mm, which can not only save space for the switch structure but also enable foreign objects to smoothly slide out from the material leakage space, improving the signal connection stability of the switch structure.

[0055] In one embodiment, as Figures 1 to 3As shown, the insulating part includes a first insulating part 3 and a second insulating part 4 arranged opposite to each other, the first contact part 11 and the second contact part 21 are located between the first insulating part 3 and the second insulating part 4, and part of the structure of the first contact part 11 is embedded in the first insulating part 3, for example, the embedded part 111 is embedded in the side of the first insulating part 3 facing the second insulating part 4, and the second terminal 2 also includes a fixed part 24 connected to the second contact part 21, and the first insulating part 3 and the second insulating part 4 are respectively located on both sides of the fixed part 24 and jointly clamp the fixed part 24 to fix the second terminal 2.

[0056] In some embodiments, such as Figure 1 、 Figure 4 and Figure 5 As shown, the first terminal 1 also includes a first soldering portion 12, which is connected to the first contact portion 11 and extends through the space between the first insulating portion 3 and the second insulating portion 4. The second insulating portion 4 has a first groove 41 formed on the side surface corresponding to the first soldering portion 12. The first soldering portion 12 extends through the first groove 41 and connects to the supporting surface. The first soldering portion 12 is used to solder the first terminal to the supporting surface, which can be, for example, the surface of a circuit board that supports the switch structure.

[0057] In one embodiment, the first welding portion 12 is flat, the first end of the first welding portion 12 is connected to the first contact portion 11, the second end of the first welding portion 12 faces the load-bearing surface, and the surface of the first welding portion 12 facing away from the first contact portion 11 constitutes the welding surface of the first welding portion 12, that is, the end surface of the second end of the first welding portion 12 is welded to the load-bearing surface.

[0058] In another embodiment, if Figure 5 As shown, the first welding portion 12 is in the shape of a bent plate. The first welding portion 12 includes a first plate portion 121 and a second plate portion 122 arranged at an angle. The first end of the first plate portion 121 is connected to the first contact portion 11, and the second end of the first plate portion 121 is connected to the second plate portion 122 and faces the load-bearing surface. The lower surface of the second plate portion 122 constitutes the welding surface of the first welding portion 12, wherein the lower surface of the second plate portion 122 can refer to the side of the second plate portion 122 facing the load-bearing surface. The angle between the first plate portion 121 and the second plate portion 122 can be set according to actual needs and is not limited to this. In this embodiment, the first plate portion 121 and the second plate portion 122 are arranged vertically to ensure good fit between the welding surface of the first welding portion 12 and the load-bearing surface, thereby improving welding strength.

[0059] In this embodiment, Figure 1 and Figure 5As shown, one end of the second plate portion 122 away from the first plate portion 121 faces away from the switch structure. This structural design can enable a higher connection strength between the switch structure and the bearing surface, preventing the switch structure from falling off the bearing surface when the switch structure is subjected to impacts such as collisions or scratches. In some other embodiments, one end of the second plate portion 122 away from the first plate portion 121 faces towards the switch structure. At this time, the welding surface of the first welding portion 12 is located between the second insulating portion 4 and the bearing surface, which can reduce the occupied area of the switch structure on the bearing surface.

[0060] In one embodiment, as Figure 3 and Figure 5 shown, a first position 113 and a second position 114 are provided on the first contact portion 11. The first position 113 is the position on the first contact portion 11 connected to the first welding portion 12, and the second position 114 is the position on the first contact portion 11 for contacting the second contact portion 21. When the first contact portion 11 contacts the second contact portion 21, the second position 114 generates heat due to signal connection, making the temperature at the second position 114 higher than that at the welding surface of the first welding portion 12. The solder at the first welding portion 12, such as tin flux, can move from the welding surface of the first welding portion 12 towards the second position 114 under the action of heat. When the solder moves to the second position 114, it will affect the signal connection between the first terminal 1 and the second terminal 2. In one example, as Figure 3 shown, a partition portion 5 is further provided in the switch structure between the first position 113 and the second position 114 for separating the solder of the first welding portion 12 from the second position 114.

[0061] In one example, the partition portion 5 is provided on the surface of the second insulating portion 4 facing the first insulating portion 3. The partition portion 5 can be, for example, an insulating column with one end connected to the surface of the second insulating portion 4 facing the first insulating portion 3, and the other end of the insulating column is connected to the first contact portion 11, preventing the solder from moving to the second position 114 through the side of the first contact portion 11 facing the second insulating portion 4. In another example, as Figures 3 to 5 shown, the partition portion 5 is provided on the surface of the first insulating portion 3 facing the second insulating portion 4 and can abut against the second insulating portion 4. With this design, the partition portion 5 can prevent the solder from moving to the second position 114 through the side of the first contact portion 11 facing the first insulating portion 3, and at the same time, it can also play a supporting role for the first insulating portion 3, making the switch structure more stable.

[0062] In one embodiment, as Figure 3 and Figure 5As shown, a via hole 115 is provided on the first contact portion 11, that is, the via hole 115 is located between the first position 113 and the second position 114. The via hole 115 can block the heat transfer from the second position 114 towards the first welding portion 12 to a certain extent, alleviating the solder movement phenomenon. The shape of the via hole 115 includes but is not limited to circular, rectangular, etc., and no limitation is imposed thereon. The first insulating portion 3 fills the via hole 115 to prevent the solder from moving to the second position 114 through the hole wall of the via hole 115. The filling method can be, for example, that the entire via hole 115 is embedded in the first insulating portion 3, or, for example, an insulating block protrudes at the position of the first insulating portion 3 corresponding to the via hole 115 to fill the via hole 115, and no limitation is imposed thereon.

[0063] Continue to refer to Figures 3 to 5 , in one embodiment, a blocking portion 5 is provided on the first insulating portion 3. One end of the blocking portion 5 is connected to the first insulating portion 3 filling the via hole 115, and the other end abuts against the second insulating portion 4. The blocking portion 5 cooperates with the first insulating portion 3 filling the via hole 115 to simultaneously achieve the blocking of the solder and the support for the first insulating portion 3, improving the signal connection stability and structural stability of the switch structure.

[0064] In one embodiment, as Figures 1 to 3 shown, the second terminal 2 further includes a first connecting portion 22 and a second welding portion 23 connected to each other. The first end of the first connecting portion 22 is connected to the second contact portion 21, and the second end of the first connecting portion 22 is connected to the second welding portion 23, that is, the first connecting portion 22 is provided between the second contact portion 21 and the second welding portion 23. Depending on the relative positions of the second contact portion 21 and the second welding portion 23, the first connecting portion 22 can be of different shapes. For example, the first connecting portion 22 can be a straight plate or a right-angled plate, and no limitation is imposed thereon. A jack 31 is provided on the first insulating portion 3 corresponding to the first connecting portion 22. During the detection process, the detection probe contacts the first connecting portion 22 by inserting into the jack 31, and can drive the second contact portion 21 to move away from the first contact portion 11 and separate from the first contact portion 11 by pressing the first connecting portion 22, so as to disconnect the signal connection between the first terminal 1 and the second terminal 2.

[0065] Continue to refer to Figures 1 to 3, in one embodiment, the second welding portion 23 extends out through the space between the first insulating portion 3 and the second insulating portion 4. A second groove 42 is formed at the side surface of the second insulating portion 4 corresponding to the second welding portion 23. The second welding portion 23 penetrates through the second groove 42 and is connected to the bearing surface. The second welding portion 23 can be, for example, a flat plate. The surface of the second welding portion 23 facing away from the second contact portion 21 constitutes the welding surface of the second welding portion 23. Alternatively, the second welding portion 23 can also be a bent plate. The second welding portion 23 includes a third plate portion 231 and a fourth plate portion 232 arranged at an angle. The third plate portion 231 is connected to the second contact portion 21, and the lower surface of the fourth plate portion 232 constitutes the welding surface of the second welding portion 23. The setting of the second welding portion 23 can refer to the first welding portion 12, which will not be elaborated here.

[0066] Continue to refer to Figures 1 to 3 , in one embodiment, the fixing portion 24 includes fixing plates 221 arranged on both sides of the first connecting portion 22, which are used to fix the second terminal 2 and enable the second terminal 2 to maintain balance when being pressed by the detection probe. The number of the fixing plates 221 can be set according to actual needs. For example, there can be two fixing plates 221, which are respectively arranged on both sides of the first connecting portion 22. The connection positions of the respective fixing plates 221 on the first connecting portion 22 can be set according to actual needs. For example, they can both be connected to the second end of the first connecting portion 22. Since the fixing plates 221 are clamped between the first insulating portion 3 and the second insulating portion 4 and fixed, the connection position between the first connecting portion 22 and the fixing plates 221 is thus fixed. When the detection probe presses the first connecting portion 22, the part of the first connecting portion 22 close to the first contact portion 11 rotates relatively around this connection position. The respective fixing plates 221 are both connected to the second end of the first connecting portion 22, which can make this connection position as far away as possible from the pressing position of the detection probe on the first connecting portion 22. Through this design, the rotation radius and the pressing stroke of the first connecting portion 22 are increased. On the one hand, the first connecting portion 22 can rebound stably. On the other hand, the pressure required to press the first connecting portion 22 by the detection probe is reduced, the separation difficulty between the first terminal 1 and the second terminal 2 is lowered, and the detection operation is facilitated.

[0067] The switch structure further includes a housing 6, which is used to hold the first terminal 1, the second terminal 2, and the insulating portion as a whole. The material of the housing 6 can be, for example, a metal housing such as an iron shell, so as to play a role in signal shielding during the detection process. In one embodiment, as Figure 1 and Figure 6As shown, the housing includes a first clamping portion 61, a second clamping portion 62, and a second connecting portion 63. The first clamping portion 61 abuts against the surface of the first insulating portion 3 facing away from the second insulating portion 4, the second clamping portion 62 abuts against the surface of the second insulating portion 4 facing away from the first insulating portion 3, and the second connecting portion 63 connects the first clamping portion 61 and the second clamping portion 62. Among them, multiple first clamping portions 61 or second clamping portions 62 can be provided. For example, two second clamping portions 62 can be provided, and an opening is formed between the two second clamping portions 62 to facilitate disassembly and repair of the switch structure through the opening. Correspondingly, multiple second connecting portions 63 are also provided for connecting the two second clamping portions 62 and the first clamping portion 61. An opening can also be provided at the position of the first clamping portion 61 corresponding to the jack 31, and this opening is used in cooperation with the jack 31 for detecting the insertion of the detection probe for detection.

[0068] The housing 6 can be fixedly connected to the bearing surface by welding, and the surface of the second clamping portion 62 facing away from the second insulating portion 4 constitutes the welding surface of the housing 6. In one embodiment, as Figures 1 to 5 shown, both the first welding portion 12 and the second welding portion 23 are bent plates. The welding surface of the first welding portion 12 is arranged farther away from the second insulating portion 4 than the welding surface of the housing 6. The second welding portion is a bent plate, and the welding surface of the second welding portion 23 is arranged farther away from the second insulating portion 4 than the welding surface of the housing 6. That is, the welding surfaces of the first welding portion 12 and the second welding portion 23 are closer to the bearing surface than the welding surface of the housing 6. Since the area of the welding surface of the housing 6 is significantly larger than the areas of the welding surfaces of the first welding portion 12 and the second welding portion 23, with this design, the welding surface of the housing 6 and the welding surfaces of the first welding portion 12 and the second welding portion 23 are respectively on planes at different heights, which can effectively prevent the solder of the first welding portion 12 and the second welding portion 23 from moving to the welding surface of the housing 6, improving the signal connection stability of the switch structure. In addition, the housing 6 can also play a protective role, avoiding damage to other parts of the switch structure and improving the service life of the switch structure.

[0069] In one embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the first connecting portion 22 has an arched structure protruding towards the jack 31. This structure enables the first connecting portion 22 to have a larger elastic deformation range, and can provide a larger pressing stroke for the first connecting portion 22 when it is pressed by the detection probe, avoiding the second connecting portion 22 from being unable to rebound due to the deformation size exceeding the elastic deformation range after being pressed.

[0070] Continue to refer to Figure 3 and Figure 4, in one embodiment, an avoidance groove 43 is provided in a region of the second insulating portion 4 corresponding to the first connecting portion 22. When the first connecting portion 22 is pressed and deformed to move towards the second insulating portion 4, the avoidance groove 43 can provide more space for the deformation of the first connecting portion 22. The shape of the avoidance groove 43 can be set according to actual needs. In one example, the avoidance groove 43 adopts a profiling structure, and its bottom surface can be designed according to the surface shape of the first connecting portion 22 after being pressed, so that the avoidance groove 43 can fit well with the first connecting portion 22 after being pressed, and prevent the avoidance groove 43 from hindering the deformation of the first connecting portion 22.

[0071] Continue to refer to Figure 3 and Figure 4 , in one embodiment, the second terminal 2 further includes elastic support arms 25 disposed on both sides of the second contact portion 21. The number of the elastic support arms 25 can be set according to actual needs. For example, there can be two elastic support arms 25, and the two elastic support arms 25 are respectively disposed on both sides of the second contact portion 21. The fixed ends of the elastic support arms 25 are connected to the second contact portion 21 or the first connecting portion 22, and the free ends of the elastic support arms 25 are in contact with the second insulating portion 4. The elastic support arms 25 and the first connecting portion 22 can form an arch-shaped structure in both the transverse direction and the longitudinal direction of the second terminal 2. When the first connecting portion 22 rebounds, the elastic support arms 25 can provide elastic support for the first connecting portion 22, ensure stable rebound, and improve the signal connection stability of the switch structure.
