Detailed implementation manners

[0032] The following will disclose multiple implementation manners of the present application with the drawings. For the sake of clear description, many implementation details will be described together in the following narration. However, it should be understood that these implementation details should not be used to limit the present application. That is to say, in some implementation manners of the present application, these implementation details are not necessary. In addition, for the sake of simplifying the drawings, some conventional structures and components will be shown in a simple schematic manner in the drawings. In the following embodiments, the same reference numerals will be used to represent the same or similar components.

[0033] Please refer to Figures 1 to 4 , Figure 1 is a perspective view of the button plug-in structure of the present application, Figure 2 is another perspective view, Figure 3 is an exploded perspective view of the button plug-in structure of the present application and Figure 4 is another exploded perspective view. As shown in the figure, the present application provides a button plug-in structure 1, which includes a circuit board 11, a socket part 12 and an elastic part 13. The circuit board 11 has a perforation 111 for providing button plug-in. The socket part 12 has a hole groove 121 and a first jack 122, and the first jack 122 is located at the bottom of the hole groove 121. The socket part 12 is fitted into the perforation 111, and the first jack 122 communicates with the perforation 111. The elastic part 13 has a second jack 131, and the elastic part 13 is assembled in the hole groove 121, and the second jack 131 communicates with the first jack 122. The button plug-in structure 1 of this implementation manner is a combination of the socket part 12 and the circuit board 11, which can provide single-button electrical plug-in. Among them, the socket part 12 combined on the circuit board 11 will not significantly increase the height of the keyboard, and the button can also be plugged, repaired or replaced at any time according to needs.

[0034] In this embodiment, the through hole 111 further includes an electrical hole 1111 and a guiding hole 1112. The electrical hole 1111 is located on one side of the guiding hole 1112. Both the electrical hole 1111 and the guiding hole 1112 are orifices for the key to be inserted. The electrical hole 1111 has a socket orifice 1113 and a positioning orifice 1114, and the socket orifice 1113 and the positioning orifice 1114 communicate with each other. The socket member 12 has a seat body portion 123 and a positioning portion 124. The positioning portion 124 extends outward from one side of the seat body portion 123. The seat body portion 123 is correspondingly fitted into the socket orifice 1113, and the positioning portion 124 is correspondingly fitted into the positioning orifice 1114. The first jack 122 is located in the seat body portion 123. The outer contour of the socket member 12 in this embodiment corresponds to the orifice contour of the electrical hole 1111 in the through hole 111 of the circuit board 11. There are two electrical holes 1111 and one guiding hole 1112. The contours of the two electrical holes 1111 can be the same or different, and there are also two socket members 12 corresponding to the two electrical holes 1111. In this way, the outer contours of the two socket members 12 can respectively correspond and match the orifice contours of the two electrical holes 1111. The user can use socket members 12 with different or the same structures to match different or the same structures of the electrical holes 1111 according to requirements.

[0035] As described above, the seat body portion 123 of the socket member 12 in this embodiment is a cylinder, and the socket orifice 1113 of the through hole 111 is also relatively a cylindrical orifice contour. The positioning portion 124 of the socket member 12 is a rectangular body, and the positioning orifice 1114 of the through hole 111 is also relatively a rectangular orifice contour. With the design of the positioning orifice 1114 of the through hole 111 of the circuit board 11 in this embodiment matching the positioning portion 124 of the socket member 12, it can effectively avoid the problem of incorrect assembly direction when the socket member 12 is assembled into the through hole 111.

[0036] Furthermore, the socket member 12 further has a limiting portion 125. The limiting portion 125 extends outward from the peripheral side of the orifice of the hole groove 121, and the limiting portion 125 abuts against the peripheral surface of the electrical hole 1111 in the through hole 111 of the circuit board 11. When the socket member 12 is fitted into the through hole 111, the embedding depth of the socket member 12 into the through hole 111 is limited by the limiting portion 125, so that the socket member 12 can just be embedded into the electrical hole 1111 of the through hole 111. The limiting portion 125 extends horizontally outward from the peripheral side of the orifice of the hole groove 121 of the seat body portion 123. The limiting portion 125 has a positioning side 1251 corresponding to the side of the guiding hole 1112. The positioning side 1251 presents an arc-shaped side corresponding to the circular orifice contour of the guiding hole 1112, and the positioning side 1251 corresponds to the side of the guiding hole 1112 adjacent to the positioning side 1251. In this way, it can also be used as a limitation for the assembly direction and assembly position of the socket member 12 when it is embedded into the through hole 111.

[0037] Please refer back to Figure 3 AndFigure 4 In this embodiment, the elastic member 13 has a main body portion 132 and two elastic sheet portions 133. The two elastic sheet portions 133 extend away from the main body portion 132 respectively from both ends of the main body portion 132, and the adjacent sides of the two elastic sheet portions 133 are close to each other. The two elastic sheet portions 133 are bent elastic sheets, and the adjacent sides of the two elastic sheet portions 133 are bent inward and close to each other. The second jack 131 is arranged on the main body portion 132, and the vertical projection position of the second jack 131 is located between the two elastic sheet portions 133. The elastic member 13 of this embodiment is integrally formed. The structure of the elastic member 13 is not limited in this embodiment and can be adjusted according to the needs of users. In addition, the elastic member 13 of this embodiment is made of metal and has elastic resilience. When the elastic sheet portions 133 of the elastic member 13 are supported and separated outward by an external force, the elastic restoring force of the elastic member 13 provides a force for inward clamping.

[0038] As described above, the elastic member 13 is assembled in the hole groove 121 of the socket member 12. The inner contour of the hole groove 121 of the socket member 12 also corresponds to the outer contour shapes of the seat body portion 123 and the positioning portion 124. The elastic member 13 is assembled in the hole groove 121 corresponding to the position of the seat body portion 123. The elastic member 13 and the socket member 12 are made of metal, and the elastic member 13 is fixed to the socket member 12 by welding methods such as wave soldering or reflow soldering. In addition, the elastic member 13 and the socket member 12 can also be assembled and fixed by the external shape structure, so that the elastic member 13 is fixed in the hole groove 121 of the socket member 12.

[0039] Please refer to Figures 5 to 8 , Figure 5 is a perspective view of the key structure of the present application, Figure 6 is another perspective view, Figure 7 is Figure 6 a cross-sectional view taken along the line A-A' of Figure 8 and Figure 7Enlarged view of the first embodiment of region B. As shown in the figure, this embodiment provides a key structure 2 with a key plugging and unplugging structure 1, and plugs the key 21 into the key plugging and unplugging structure 1. In this embodiment, the key 21 has two electrical pins 211 and a guiding post 212. The guiding post 212 is located at the center of the key 21, and the two electrical pins 211 are located on one side of the guiding post 212. The electrical pin 211 is plugged into the electrical hole 1111 of the through hole 111, so that the electrical pin 211 is plugged into the socket member 12 and the elastic member 13. One end of the electrical pin 211 is sequentially plugged through the first jack 122 of the socket member 12 and the second jack 131 of the elastic member 13. When the electrical pin 211 passes between the two elastic pieces 133, the electrical pin 211 pushes the two elastic pieces 133 outwards. The elastic restoring force of the two elastic pieces 133 of the elastic member 13 acts inwards, so that the two elastic pieces 133 elastically fix the electrical pin 211. In other words, the electrical pin 211 is clamped and fixed by the two elastic pieces 133. At the same time, the electrical pin 211 and the two elastic pieces 133 of the elastic member 13 can be electrically connected to each other because they are both made of conductive materials. In addition, the guiding post 212 is plugged into the guiding hole 1112 of the through hole 111, so as to assist in installing the key 21 at the central position of the key plugging and unplugging structure 1.

[0040] Please refer back to Figure 8 , the two elastic pieces 133 of the elastic member 13 in this embodiment are bent elastic pieces, and the adjacent sides of the two elastic pieces 133 are bent with multiple included angles towards each other. Among them, Figure 8 each single elastic piece 133 has been bent at least twice, and the elastic piece 133 has at least two included angles, so that the contact surface of the electrical pin 211 relative to the two elastic pieces 133 is a plane. In addition, the number of bends of the elastic piece 133 in this embodiment is not limited. After the single elastic piece 133 is bent at least once, the bent part of the elastic piece 133 can touch the electrical pin 211, and the above-mentioned number of bends can be adjusted according to the user's needs.

[0041] Please refer to Figure 9 , which is Figure 7 Enlarged view of the second embodiment of region B. As shown in the figure, the difference between the elastic member 13 in this embodiment and the elastic member in Figure 8 lies in the bending method. The two elastic pieces 133 of the elastic member 13 in this embodiment are bent elastic pieces, and the adjacent sides of the two elastic pieces 133 are bent towards each other in an arc shape, so that the contact surface of the electrical pin 211 relative to the two elastic pieces 133 is an arc surface.

[0042] Please refer to Figure 10 , which is Figure 7 Enlarged view of the third embodiment of region B. As shown in the figure, the difference between the elastic member 13 in this embodiment and the elastic member in Figure 8The difference in the elastic member lies in the bending method. The two elastic sheet portions 133 are bent elastic sheets, and are a kind of inverted hook-shaped bent elastic sheets. After one end of the two elastic sheet portions 133 bends towards each other, one end of the two elastic sheet portions 133 bends and extends towards the body portion 132 and away from the vertical projection position of the second jack 131. In this way, when the electrical pin 211 is inserted relative to the two elastic sheet portions 133, the electrical pin 211 will first pass through one end of the two elastic sheet portions 133 that are away from each other, and then contact the adjacent portion of the two elastic sheet portions 133. When one end of the electrical pin 211 moves and is inserted into the elastic member 13, and the insertion direction of one end of the electrical pin 211 has a slight deviation, one end of the two elastic sheet portions 133 that are away from each other can accommodate one end of the electrical pin 211 with a deviation in the insertion direction. When one end of the electrical pin 211 moves and touches any one end of the two elastic sheet portions 133 that are away from each other, one end of the electrical pin 211 will move along the inner surface of the elastic sheet portion 133 along the trend, so as to guide the electrical pin 211 to move towards the adjacent portion of the two elastic sheet portions 133 along the trend, and then the electrical pin 211 is clamped and contacted by the adjacent portion of the two elastic sheet portions 133. The present application does not limit the structure of the elastic member 13, and the elastic member 13 can be selected with a suitable structure according to the needs of the user.

[0043] Please refer to Figure 11 , which is Figure 7 An enlarged view of the fourth embodiment of region B of. As shown in the figure, the elastic member 13 of the present embodiment is different from the elastic member of Figure 10 in the bending method and the number of bends. The elastic member 13 of the present embodiment has a body portion 132 and an elastic sheet portion 133. The elastic sheet portion 133 extends from one end of the body portion 132 in a direction away from the body portion 132, and one side of the elastic sheet portion 133 approaches the vertical projection position of the second jack 131. Among them, the elastic sheet portion 133 is a bent elastic sheet, and the elastic sheet portion 133 shows an inward bending and approaching. The elastic sheet portion 133 is a bent elastic sheet, and is a kind of inverted hook-shaped bent elastic sheet. After one end of the elastic sheet portion 133 is bent, one end of the elastic sheet portion 133 bends and extends towards the body portion 132 and away from the vertical projection position of the second jack 131, and the bent portion of the elastic sheet portion 133 is close to the vertical projection position of the second jack 131. The effect that one end of the elastic sheet portion 133 is away from the vertical projection position of the second jack 131 is as described in the previous paragraph for guiding the insertion direction of the electrical pin 211, so it will not be repeated here.

[0044] The present embodiment further provides a keyboard, and the keyboard includes a plurality of key structures 2 having a key plugging and unplugging structure 1. The present embodiment can apply a plurality of key structures 2 having a key plugging and unplugging structure 1 to various mechanical keyboards, so as to improve the disadvantage that the mechanical keyboard is too heavy.
