DETAILED DESCRIPTION

[0042] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0043] In the production process of circuit boards of electronic devices, in order to ensure the stability of signal connection, it is necessary to perform external RF signal detection on the electrical connector. In the prior art, an RF detection switch is usually used for this detection. Exemplarily, the RF detection switch includes a first terminal and a second terminal, and the first terminal and the second terminal can be in contact to maintain signal connectivity. When performing external RF signal detection, the second terminal is pressed by the detection probe to separate the second terminal from the first terminal and disconnect the signal connection, thereby conducting the signal connection between the detection probe and the second terminal. In the prior art, due to the small size of the switch structure and the terminals being located inside the switch structure, when there is foreign matter or dirt at the contact point between the first terminal and the second terminal, it is difficult for the inspector to clean the terminal, and the foreign matter or dirt forms a barrier to the contact point, affecting the signal connectivity of the switch structure.

[0044] In order to solve the above technical problems, the present disclosure provides a terminal, a switch structure and an electronic device. The terminal provided by the present disclosure is used in conjunction with a mating terminal, wherein the terminal may be, for example, the aforementioned first terminal, and the mating terminal may be, for example, the aforementioned second terminal. The terminal includes a first fixed portion and at least one first contact portion connected to the first fixed portion, and the first contact portion can contact or separate from the second contact portion of the mating terminal, thereby realizing signal connection or disconnection. During the mating process between the terminal and the mating terminal, the contact surface of the first contact portion in contact with the second contact portion is subjected to a scraping action, and foreign matter or dirt located at the contact point between the first contact portion and the second contact portion can be removed by the scraping action, thereby keeping the terminal contact point clean and ensuring the signal connection stability of the switch structure. In addition, the scraping action enables foreign matter or dirt to leave the terminal contact point in time, preventing foreign matter or dirt from causing damage such as contamination or corrosion to the terminal contact point, and effectively extending the service life of the switch structure and the electronic device.

[0045] An exemplary embodiment of the present disclosure provides a terminal for use with a mating terminal, such as Figure 1 As shown, the first terminal 1 is a terminal provided in this embodiment, and the second terminal 2 is a mating terminal. The first terminal 1 includes a first fixing portion 13 and at least one first contact portion 11 connected to the first fixing portion 13, the first fixing portion 13 is used to fix the first terminal 1, and the second terminal 2 includes a second contact portion 21, the first contact portion 11 can contact with the second contact portion 21 to achieve the connection of the signal connection between the first terminal 1 and the second terminal 2, and the first contact portion 11 can be separated from the second contact portion 21 to achieve the disconnection of the signal connection between the first terminal 1 and the second terminal 2. The surface on the first contact portion 11 used for contacting or separating with the second contact portion 21 is the contact surface 111, that is, the second contact portion 21 controls whether the signal connection is connected by contacting or separating with the contact surface 111. The specific shape of the second terminal 2 can be set according to actual needs, and the second terminal 2 can be a variety of shapes including but not limited to a linear plate or a right-angle plate, which is not limited to this.

[0046] The contact surface is configured such that the second contact portion scrapes the contact surface during the cooperation between the second contact portion and the contact surface.

[0047] The first contact portion 11 is configured so that the second contact portion 21 scrapes the contact surface 111 during the cooperation between the second contact portion 21 and the contact surface 111. Figure 1 As shown, when the second contact portion 21 cooperates with the contact surface 111, the second contact portion 21 can move on the surface of the contact surface 111, and thus the contact surface 111 is scratched. Figure 1 As shown, the second contact portion 21 can move directly on the contact surface 111 , so that the second contact portion 21 scrapes the contact surface 111 .

[0048] By adopting such a setting mode, during the mating process between the first terminal 1 and the second terminal 2, the contact surface 111 on the first contact portion 11 that contacts the second contact portion 21 is scratched, and foreign matter or dirt located at the contact point between the first contact portion 11 and the second contact portion 21 can be removed by the scraping action, so as to keep the terminal contact clean and ensure the signal connection stability of the switch structure. In addition, the scraping action enables foreign matter or dirt to leave the terminal contact point in time, preventing foreign matter or dirt from causing damage such as contamination or corrosion to the terminal contact point, and effectively extending the service life of the switch structure and the electronic device.

[0049] In one embodiment, if Figure 1 As shown, the contact surface 111 is arranged at a non-vertical angle with the first direction, and the first direction refers to the relative movement direction between the second contact portion 21 and the first contact portion 11 (for example Figure 1 +y direction as shown), that is, the straight line where the relative movement direction of the second contact portion 21 and the first contact portion 11 is located is parallel to or non-perpendicular to the plane where the contact surface 111 is located. In one embodiment, the contact surface 111 is arranged parallel to the first direction, and the second contact portion 21 does not apply additional pressure to the contact surface 111 when moving on the surface of the contact surface 111, which can effectively reduce the wear of the contact surface 111 caused by the scraping effect. On the one hand, it can extend the service life of the first terminal 1, and on the other hand, it can prevent the contact surface 111 from affecting the use effect of the switch structure due to excessive wear. In other embodiments, the plane where the contact surface 111 is located is arranged non-perpendicularly to the first direction, so that the second contact portion 21 can apply a pressure perpendicular to the contact surface 111 to the contact surface 111 while moving on the surface of the contact surface 111, so as to effectively enhance the scraping strength, and even for stubborn foreign matter and dirt, it can have a good cleaning effect, and improve the cleaning ability of the terminal structure.

[0050] Continue to refer Figure 1 In one embodiment, the position where the second contact portion 21 can be separated from the contact surface 111 is the first position of the second contact portion, and the position where the second contact portion 21 can contact the contact surface 111 is the second position of the second contact portion. For example, when the detection probe presses the second contact portion 21 downward, the part of the structure on the second contact portion 21 that is used to contact the contact surface 111 moves downward and is thus separated from the contact surface 111. At this time, the first position is below the second position. Along the direction from the first position of the second contact portion 21 to the second position, the contact surface 111 tilts toward the direction close to the second contact portion 21. Figure 1Since the first position is located below the second position, the upper structure of the contact surface 111 is inclined toward the direction close to the second contact portion 21 from the first position to the second position, that is, from bottom to top, and the lower structure of the contact surface 111 is inclined toward the direction away from the second contact portion 21. With such a setting, when part of the structure of the second contact portion 21 moves due to being pressed, the distance between the contact surface 111 and the second contact portion 21 can be gradually increased, and finally the contact surface 111 and the second contact portion 21 are separated.

[0051] When the first contact portion 11 and the second contact portion 21 are both rigid parts and are rigidly connected, the second contact portion 21 is blocked after contacting the first contact portion 11 and stops moving, resulting in the scraping action not being completed smoothly. To avoid this, an elastic member is provided in the first contact portion 11. Figure 1 In one embodiment, the first contact portion 11 includes an elastic contact plate 110, and the first terminal 1 also includes a connecting arm 12. The first end of the connecting arm 12 is connected to the elastic contact plate 110, and the second end of the connecting arm 12 is connected to the first fixing portion 13, that is, the elastic contact plate 110 is connected to the first fixing portion 13 through the connecting arm 12. The elastic contact plate 110 can be elastically deformed after being subjected to force, and the second contact portion 21 and the elastic contact plate 110 can complete the scraping action through this elastic deformation. For example, the contact surface 111 of the elastic contact plate 110 is an elastic contact surface. When scraping, the contact surface 111 correspondingly produces an elastic deformation that is concave inward, providing an action space for the scraping action. For another example, the connection part of the elastic contact plate 110 with the connecting arm 12 is an elastic connecting part. When scraping, the elastic contact plate 110 correspondingly undergoes elastic displacement, and the distance between the contact surface 111 and the second contact portion 21 is adjusted to ensure that the scraping action can be completed.

[0052] Continue to refer Figure 1In one embodiment, two first contact portions 11 are provided, which can be respectively arranged on both sides of the second contact portion 21, and the elastic contact plates 110 of the two first contact portions 11 are arranged opposite to each other, and in the direction away from the first fixing portion 13, the spacing between the elastic contact plates 110 of the two first contact portions 11 gradually decreases, that is, the elastic contact plates 110 of the two first contact portions 11 are arranged in an eight-shaped shape, and the surface of the elastic contact plate 110 opposite to the other elastic contact plate 110 constitutes a contact surface 111, that is, the vertical distance between the contact surfaces 111 of the two first contact portions 11 gradually decreases along the direction from the first position to the second position of the second contact portion 21. With such a setting, on the one hand, multiple points of contact are formed between the first terminal 1 and the second terminal 2. When one of the first contact parts 11 cannot be used due to a malfunction or other reasons, the first contact part 11 can still achieve signal connection with the second contact part 21 through other protrusions 112, thereby improving the signal connection stability of the switch structure. On the other hand, when scraping, the two first contact parts 11 clamp the second contact part 21, so that the moving direction of the first contact part 21 always remains upright, thereby preventing the second contact part 21 from being offset due to the reaction force of the first contact part 11.

[0053] In an example, Figure 1 As shown, a leakage space is formed between the contact surfaces 111 of the two elastic contact plates 110, and foreign matter or dirt separated from the contact surface 111 by scraping can leave the first terminal 1 and the second terminal 2 through the leakage space, preventing the foreign matter or dirt from falling from the contact surface 111 to the second contact portion 21, thereby hindering the signal connection between the first terminal 1 and the second terminal 2. In addition, the leakage space can also make foreign matter slide out of the second contact portion 21. When there is foreign matter on a part of the structure of the second contact portion 21, as the detection probe presses the second terminal 2, the second contact portion 21 moves in a direction away from the first contact portion 11 and makes a part of the structure in the second terminal 2 tilt downward, thereby making the foreign matter slide along the second contact portion 21 to the leakage space and can slide out of the leakage space and leave the switch structure, thereby ensuring the signal connection stability of the switch structure.

[0054] An exemplary embodiment of the present disclosure provides a switch structure, which may be, for example, a radio frequency switch structure. Figures 1 to 3 As shown, the switch structure includes a first terminal 1 and a second terminal 2, and the first terminal 1 can be the first terminal 1 in any of the above embodiments. The second terminal 2 includes a second contact portion 21, and the second contact portion 21 can contact or separate from the contact surface 111 of the first terminal 1, and scrape the contact surface 111 during the cooperation process with the contact surface 111. The specific settings of the first terminal 1 and the second terminal 2 in the switch structure can refer to the first terminal 1 and the second terminal 2 in any of the above embodiments, and will not be repeated here.

[0055] By adopting such a setting mode, during the matching process between the first terminal 1 and the second terminal 2, the contact surface 111 on the first contact portion 11 that contacts the second contact portion 21 is scratched, and foreign matter or dirt located at the contact point between the first contact portion 11 and the second contact portion 21 can be removed by the scraping action, so as to keep the terminal contact clean and ensure the signal connection stability of the switch structure. In addition, the scraping action enables foreign matter or dirt to leave the terminal contact point in time, preventing foreign matter or dirt from causing damage such as contamination or corrosion to the terminal contact point, and effectively extending the service life of the switch structure.

[0056] In one embodiment, if Figure 2 and Figure 3 As shown, the switch structure also includes a first insulating portion 3 and a second insulating portion 4 that are arranged opposite to each other, and the first contact portion 11 and the second contact portion 21 are both located between the first insulating portion 3 and the second insulating portion 4. The first insulating portion 3 and the second insulating portion 4 can maintain the structural stability of the switch structure and protect the terminal structure. A plug hole 31 is provided at a position corresponding to the second contact portion 21 on the first insulating portion 3. During the detection process, the detection probe contacts the second contact portion 21 by inserting into the plug hole 31, and can press the second contact portion 21 to move the portion of the second contact portion 21 that is used to contact the first contact portion 11 in a direction away from the first contact portion 11 and separate from the first contact portion 11, so as to disconnect the signal connection between the first terminal 1 and the second terminal 2.

[0057] Part of the structure of the first contact portion 11 is embedded in the first insulating portion 3, so that the first contact portion 11 is fixed on the first insulating portion 3, thereby limiting and shaping the first contact portion 11. Figure 1 and Figure 4 As shown, the end of the elastic contact plate 110 facing the first insulating part 3 is embedded in the first insulating part 3, or other structures in the first contact part 11 are embedded in the first insulating part 3, and there is no limitation on this. Among them, the part of the first contact part 11 embedded in the first insulating part 3 can be close to the part in contact with the second contact part 21, or the part of the first contact part 11 embedded in the first insulating part 3 can be connected to the part in contact with the second contact part 21, so as to further improve the fixing effect of the first insulating part 3 on the first contact part 11.

[0058] In one embodiment, if Figure 1 and Figure 4As shown, the first end of the elastic contact plate 110 of the first contact portion 11 is connected to the first end of the connecting arm 12 of the first terminal 1, and the second end of the connecting arm 12 is connected to the first fixing portion 13 of the first terminal 1, that is, the first end of the elastic contact plate 110 is connected to the first fixing portion 13 through the connecting arm 12, and the second end of the elastic contact plate 110 is embedded in the first insulating portion 3, thereby the elastic contact plate 110 can be fixed by the first fixing portion 13 and the first insulating portion 3, thereby improving the structural stability of the switch structure.

[0059] Continue to refer to Figure 1 and Figure 4 In one embodiment, one end of the first fixing portion 13 connected to the connecting arm 12 abuts against the first insulating portion 3, and from the first fixing portion 13 toward the elastic contact plate 110, the connecting arm 12 tilts away from the first insulating portion 3, and one end of the connecting arm 12 connected to the elastic contact plate 110 abuts against the second insulating portion 4. Figure 1 and Figure 4 As shown, the first end of the connecting arm 12 abuts against the second insulating part 4, and the second end of the connecting arm 12 abuts against the first insulating part 3. Since the end of the elastic contact plate 110 away from the connecting arm 12 is embedded in the first insulating part 3, this structural setting method forms a triangular structure with structural stability between the elastic contact plate 110, the connecting arm 12 and the first insulating part 3, and the first insulating part 3 and the second insulating part 4 thus form a stable support for the first terminal 1. With this setting method, the first terminal 1 is effectively fixed, and the elastic contact plate 110 is prevented from shaking or deforming due to other reasons other than scratching, so that the first terminal 1 and the second terminal 2 can stably maintain a contact or separation state during the detection process, improve the stability of the switch structure, and ensure that the detection probe can stably conduct the signal to the detection instrument during the detection process.

[0060] In one embodiment, if Figure 3 and Figure 4 As shown, the second insulating part 4 is provided with a plurality of protrusions protruding from the surface toward the first insulating part 3, and each protrusion is used to abut against a different position of the connecting arm 12, providing a plurality of support points for the connecting arm, so that the protrusions can effectively limit the connecting arm, thereby enhancing the stability of the triangular structure between the connecting arm 12, the elastic contact plate 110 and the first insulating part 3.

[0061] Continue to refer Figure 3 and Figure 4In one embodiment, the plurality of protrusions include a first protrusion 51 and a second protrusion 52. The first protrusion 51 abuts against one end of the connecting arm 12 connected to the elastic contact plate 110, and the second protrusion 52 abuts against one end of the connecting arm 12 connected to the first fixing portion 13, that is, the first end of the connecting arm 12 abuts against the first protrusion 51, and the second end of the connecting arm 12 is connected to the second protrusion 52. The first protrusion 51 and the second protrusion 52 simultaneously support both ends of the connecting arm 12, effectively preventing the connecting arm 12 from shifting or deforming. The height of the first protrusion 51 may be smaller than that of the second protrusion 52, so that when the two ends of the connecting arm 12 abut against the first protrusion 51 and the second protrusion 52 respectively, it is convenient to stably maintain the aforementioned position state of being inclined from the first fixing portion 13 to the direction of the elastic contact plate 110 and away from the first insulating portion 3. In one embodiment, the first protrusion 51 and the second protrusion 52 are arranged in one-to-one correspondence with the connecting arms 12, and each connecting arm 12 is connected to the first protrusion 51 and the second protrusion 52 to further improve the structural stability of the first terminal 1 in the switch structure.

[0062] In one embodiment, if Figure 3 and Figure 4 As shown, the second insulating portion 4 is provided with a third protrusion 53 protruding from the surface toward the first insulating portion 3, and the free end of the third protrusion 53 abuts against the first insulating portion 3 to support the first insulating portion 3, so that a stable space for accommodating a part of the structure of the first terminal 1 and the second terminal 2 is formed between the first insulating portion 3 and the second insulating portion 4, and provides space for the deformation of the second contact portion 21 when it is pressed. The third protrusions 53 are provided on both sides of the second contact portion 21 to maintain the support balance on both sides of the first insulating portion 3. The number and position of the third protrusions 53 can be set according to actual needs. In this embodiment, as shown in FIG. Figure 3 and Figure 4 As shown, two third protrusions 53 are provided near one side of the second insulating portion 4 facing the first insulating portion 3 away from the first protrusion 51 and the second protrusion 52, respectively located on both sides of the second contact portion 21, so as to further improve the support balance. In another embodiment, a fourth protrusion (not shown in the drawings) is provided on the surface of the first insulating portion 3 facing the second insulating portion 4, and the fourth protrusion is provided on both sides of the second contact portion 21. The fourth protrusion is also used to provide effective support for the first insulating portion 3, wherein the specific configuration of the fourth protrusion can refer to the third protrusion 53, and will not be repeated here.

[0063] In one embodiment, if Figures 1 to 3As shown, the second contact portion 21 is an arched structure protruding toward the insertion hole 31. This structure enables the second contact portion 21 to have a larger elastic deformation range, and can provide a larger pressing stroke for the second contact portion 21 when pressed by the detection probe, thereby preventing the second contact portion 21 from being unable to rebound after being pressed due to the deformation size exceeding the elastic deformation range.

[0064] In one embodiment, if Figures 1 to 3 As shown, the first fixing portion 13 includes a first connecting portion 131 and a second connecting portion 132 arranged at an angle, the first end of the first connecting portion 131 is connected to the first contact portion 11 through the connecting arm 12, the second insulating portion 4 is provided with a first groove 41 at the side surface corresponding to the first connecting portion 131, the second end of the first connecting portion 131 passes through the first groove 41 and is connected to the second connecting portion 132, the second connecting portion 132 abuts against the surface of the second insulating portion 4 that is away from the first insulating portion 3, that is, the second connecting portion 132 is located between the second insulating portion 4 and the bearing surface, the surface of the second connecting portion 132 that is away from the second insulating portion 4 constitutes the welding surface of the first terminal 1, and the first terminal 1 is welded to the bearing surface through the welding surface, wherein the bearing surface can be, for example, the surface of the circuit board that carries the switch structure. The angle between the first connecting portion 131 and the second connecting portion 132 can be set according to actual needs, and there is no limitation on this. In this embodiment, the first connecting portion 131 and the second connecting portion 132 are arranged vertically so that the welding surface of the first terminal 1 and the bearing surface are well fitted to improve the welding strength.

[0065] In another embodiment, if Figures 1 to 4 As shown, the second terminal 2 also includes a second fixing portion 22 connected to the second contact portion 21, the second fixing portion 22 includes a third connecting portion 221 and a fourth connecting portion 222 arranged at an angle, the third connecting portion 221 is connected to the second contact portion 21, and the second insulating portion 4 is provided with a second groove 42 at the side surface corresponding to the third connecting portion 221, the third connecting portion 221 penetrates the second groove 42 and is connected to the bearing surface and is connected to the fourth connecting portion 222, the fourth connecting portion 222 abuts against the surface of the second insulating portion 4 that is away from the first insulating portion 3, and the surface of the fourth connecting portion 222 that is away from the second insulating portion 4 constitutes the welding surface of the second terminal 2. The specific configuration of the second fixing portion 22 can refer to the first fixing portion 21, and will not be repeated here.

[0066] In one embodiment, the first fixing portion 13 or the second fixing portion 22 is a bent plate-like structure, wherein at least one of the first connecting portion 131, the second connecting portion 132, the third connecting portion 221 and the fourth connecting portion 222 is a plate-like structure, so that the welding surface of the first terminal 1 or the second terminal 2 is a plane, which can significantly increase the welding area between the terminal structure and the bearing surface. Figures 1 to 4As shown, the first fixing portion 13 and the second fixing portion 22 may both be bent plate-like structures, and the first connecting portion 131 , the second connecting portion 132 , the third connecting portion 221 and the fourth connecting portion 222 may also be plate-like structures, further enhancing the welding strength of the terminal structure.

[0067] The switch structure further includes a housing 6 for fixing the first terminal 1, the second terminal 2, the first insulating portion 3 and the second insulating portion 4 as a whole. The housing 6 may be made of a metal housing such as an iron shell to shield the signal during the detection process. Figure 2 , Figure 3 and Figure 6 As 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 away from the second insulating portion 4, the second clamping portion 62 abuts against the surface of the second insulating portion 4 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.

[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. Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the welding surface of the first terminal 1 is arranged away from the second insulating portion 4 compared with the welding surface of the housing 6, and the welding surface of the second terminal 2 is arranged away from the second insulating portion 4 compared with the welding surface of the housing 6, that is, the welding surfaces of the first terminal 1 and the second terminal 2 are closer to the bearing surface than the welding surface of the housing 6. Since the welding surface area of ​​the housing 6 is significantly larger than the welding surface area of ​​the first terminal 1 and the second terminal 2, this design makes the welding surface of the housing 6 and the welding surfaces of the first terminal 1 and the second terminal 2 respectively in planes of different heights, which can effectively prevent the solder of the first terminal 1 and the second terminal 2 from moving to the welding surface of the housing 6, thereby improving the signal connection stability of the switch structure. In addition, the housing 6 can also play a protective role, preventing other parts of the switch structure from being damaged, and improving the service life of the switch structure.

[0069] Continue to refer Figure 3 and Figure 5In one embodiment, an avoidance groove 43 is provided on the second insulating portion 4 in an area corresponding to the second contact portion 21. When the second contact portion 21 is deformed after being pressed and moves toward the second insulating portion 4, the avoidance groove 43 can provide a larger space for the deformation of the second contact portion 21. The shape of the avoidance groove 43 can be set according to actual needs. In one example, the avoidance groove 43 adopts a contour structure, and its bottom surface can be designed according to the surface shape of the second contact portion 21 after being pressed, so that the avoidance groove 43 can fit well with the second contact portion 21 after being pressed, so as to avoid the avoidance groove 43 from hindering the deformation of the second contact portion 21, thereby improving the signal connection stability of the switch structure.
