[0002] With the development of science and technology, large-scale integrated circuits are widely used in electronic products. However, with the continuous improvement of integration, the internal insulation layer in the integrated circuit is getting thinner and thinner, the connection spacing is getting smaller and smaller, the mutual breakdown voltage is getting smaller and smaller, and the anti-static ability of the integrated circuit is getting worse and worse.

[0030] See also Figures 1 to 5 An embodiment of the present application provides a protective switch, which includes a cap body assembly 100, a switch button 200 and a base 300 arranged in sequence, the switch button 200 includes an axially connected flexible conductor 210 and a rigid conductor 220, the flexible conductor 210 is connected to the base 300, and the rigid conductor 220 is connected to the cap body assembly 100.

[0031] In this embodiment, the switch button 200 is configured as a composite component including at least a flexible conductor 210 and a rigid conductor 220. On the one hand, the electrical connection between the cap assembly 100 and the base 300 can be achieved through the cooperation of the flexible conductor 210 and the rigid conductor 220, avoiding the situation that the traditional protective switch needs to achieve electrical conduction between the cap assembly 100 and the base 300 through a spring configured on the outside of the switch button 200, simplifying the structure of the protective switch, and facilitating the miniaturization layout of the protective switch. On the other hand, the flexible conductor 210 is used to provide the cap assembly 100 with a flexible buffer force in the pressing direction Z, avoiding the external pressing force from causing the switch button 200 to directly hit / collide on the conductive position of the base 300, improving the safety of the pressing operation, and extending the service life of the protective switch; the rigid conductor 220 makes the switch button 200 have a certain rigidity, making the connection between the cap assembly and the switch button 200 tighter and more stable. In this way, by optimizing the specific configuration of the switch button 200, the switch button 200 is made to have flexibility, rigidity and conductivity at the same time, so as to provide a buffer force to the cap body assembly 100 while ensuring the connection stability between the switch button 200 and the cap body assembly 100, and realizing the electrical conduction between the cap body assembly 100 and the base 300. The need to add spring components and inspection processes in the traditional protective switch structure is avoided, the structure and production process of the protective switch are simplified, the production efficiency is improved, and the production cost is reduced. In addition, since no spring is used in this embodiment, no vibration will occur during the use of the protective switch, the noise is low, and the mute effect is good, which is conducive to improving the user experience.

[0032] Specifically, the protective switch is configured as a composite component including at least a cap assembly 100, a switch button 200 and a base 300. The base 300 may be an inverted U-shaped plate, including a circuit board and two legs arranged on both sides of the circuit board and extending downward. The switch button 200 is arranged on the circuit board, and it and the legs are respectively located on both sides of the circuit board. The cap assembly 100 may be a metal material component, which is conductive and can introduce external static electricity formed by a test fixture or a human body into the switch button 200. The switch button 200 may be a tower column structure, which may be connected to the base 300 by bonding or welding. The switch button 200 is configured as a composite component including at least a flexible conductor 210 and a rigid conductor 220. The flexible conductor 210 may be a component with relatively large flexibility such as conductive silicone, which is used to provide a buffer force in the protective switch pressing direction Z to the switch button 200, thereby preventing the switch button 200 from being directly impacted against the base 300 by external force, thereby causing damage to the switch button 200 and the circuit on the base 300, thereby improving operation safety. The rigid conductor 220 may be a conductive metal component, such as an aluminum foil with a certain thickness, which is used to provide a certain rigidity to the switch button 200, thereby enabling it to have good contact and stable connection with the cap body assembly 100, and at the same time, it may also prevent the switch button 200 from being excessively squeezed and damaged under the action of external force, thereby extending the service life of the switch button 200.

[0033] In a possible implementation, the thickness of the rigid conductor 220 is 0.1 mm to 0.3 mm. This configuration can not only enable the switch button 200 to have a certain rigid support force, but also avoid the switch button 200 being too strong in the pressing direction Z, which causes the pressing to be laborious, making the protective switch easy to operate and improving the user experience. For example, but not limited to, the thickness of the rigid conductor 220 is 0.2 mm.

[0034] See also Figures 1 to 3 In a possible implementation, the flexible conductor 210 includes a conductive plate 211 and a conductive column 212 connected to each other, the conductive plate 211 is attached to the base 300 , and the rigid conductor 220 is disposed on a side of the conductive column 212 away from the conductive plate 211 .

[0035] In this embodiment, the specific configuration of the flexible conductor 210 is optimized. Specifically, the flexible conductor 210 is configured as a composite component including at least a conductive disk 211 and a conductive column 212. The conductive disk 211 can be a suction cup-shaped conductive silicone body, whose large-size end contacts the base 300 to increase the contact area between the switch button 200 and the base 300 and improve the connection stability between the switch button 200 and the base 300; and its small-size end is connected to the conductive column 212. The conductive column 212 can be a cylindrical conductive silicone body, whose radial size is equivalent to the radial size of the small-size end of the conductive disk 211. It can be integrally formed with the conductive disk 211 to improve the aesthetics and structural stability of the switch button 200, reduce subsequent assembly processes, and improve assembly efficiency; it can also be separately provided with the conductive disk 211, and then connected together by welding or bonding, etc., to facilitate maintenance and replacement.

[0036] See also Figures 1 to 3 In a possible implementation, the radial dimension of the conductive disk 211 is greater than or equal to the radial dimension of the conductive column 212, and the axial dimension of the conductive disk 211 is smaller than the axial dimension of the conductive column 212. In this way, the contact area between the switch button 200 and the base 300 can be increased by the conductive disk 211, thereby improving the connection stability between the switch button 200 and the base 300; and the buffering force of the switch button 200 in the pressing direction Z can be increased by the conductive column 212, thereby enhancing the protection and safety of the switch button 200. It should be explained that the axial direction of the conductive disk 211 is in the same direction as the pressing direction Z, and the radial direction of the conductive disk 211 is perpendicular to the axial direction of the conductive disk 211.

[0037] See also Figures 1 to 3 In a possible implementation, the cap body assembly 100 includes a top cap 110, a support column 120 and a balance beam 130, the support column 120 is disposed between the top cap 110 and the balance beam 130, and the side of the balance beam 130 away from the top cap 110 is connected to the rigid conductor 220.

[0038] In this embodiment, the specific configuration of the cap body assembly 100 is optimized. Specifically, the cap body assembly 100 is configured as a composite component including at least a top cap 110, a support column 120 and a balance beam 130. The top cap 110 can be a square plate-like structure, and its outer side is used for contact with a test fixture or a human body for pressing, which is convenient for pressing. The support column 120 can be a cylindrical structure, connected to the inside of the top cap 110, and used to provide a support force in the pressing direction Z to the top cap 110. The balance beam 130 can be a square plate-like structure, and its size is comparable to or slightly smaller than the size of the top cap 110, and is used to fix the support column 120 and contact the switch button 200 arranged below it. In this way, the cap body assembly 100 with an approximately I-shaped layout has a compact structure, occupies a small space, and is convenient for pressing; and the entire structure has a strong balance, a high sensitivity of the protective switch, and excellent anti-static performance.

[0039] See also Figures 1 to 4 In a possible implementation, the cap body assembly 100 further includes a protective cover 140 , which is sleeved on the outside of the support column 120 , and the protective cover 140 is located between the balance beam 130 and the top cap 110 .

[0040] In this embodiment, the specific configuration of the cap assembly 100 is further optimized. Specifically, the cap assembly 100 is configured as a composite component including at least a top cap 110, a support column 120, a balance beam 130, and a protective cover 140. The protective cover 140 may be a sleeve structure, which is sleeved on the outside of the support column 120 to protect the support column 120 from scratches / collisions caused by external mechanical forces, thereby extending the service life of the support column 120. At the same time, the protective cover 140 is configured between the balance beam 130 and the top cap 110, which can further enhance the structural consistency and stability of the cap assembly 100.

[0041] See also Figures 1 to 4 In a possible implementation, two support columns 120 are provided, and the protective cover 140 includes a connecting portion 141 and two sleeve portions 142 . The two sleeve portions 142 are respectively arranged on opposite sides of the connecting portion 141 . The sleeve portions 142 are provided with sleeve holes 143 , and one support column 120 is inserted into one sleeve hole 143 .

[0042] In this embodiment, the specific configuration of the protective sleeve 140 is optimized. Specifically, the protective sleeve 140 is configured as a composite structure including at least a connecting portion 141 and a sleeve portion 142, wherein the connecting portion 141 may be a plate-like structure, and the sleeve portion 142 may be a sleeve structure. The two sleeve portions 142 may be connected to both sides of the connecting portion 141 by bonding or welding, and the plane where the connecting portion 141 is located is on the same plane as the axis of the two sleeve portions 142. In this way, the two support columns 120 can be protected by a protective sleeve 140 at the same time, thereby improving the structural consistency of the cap assembly 100; and, the two sleeve portions 142 are connected by the connecting portion 141, and the two support columns 120 are respectively inserted into the corresponding sleeve portions 142, so as to further enhance the guiding consistency of the two support columns 120, so that the two support portions have the effect of following each other, thereby improving the operational stability of the cap assembly 100.

[0043] See also Figure 1 and Figure 3 In a possible implementation, the cap body assembly 100 further includes a limiting beam 150 having a movable hole 151 , the limiting beam 150 is sleeved on the outer side of the support column 120 through the movable hole 151 , and the limiting beam 150 is located between the top cap 110 and the protective cover 140 .

[0044] In this embodiment, the specific configuration of the cap assembly 100 is further optimized. Specifically, the cap assembly 100 is configured as a composite component including at least a top cap 110, a support column 120, a balance beam 130, a protective cover 140 and a limiting beam 150. The limiting beam 150 can be a cubic block structure, and its plane size is larger than the plane size of the top cap 110. The projection of the top cap 110 on the base 300 completely falls into the projection of the limiting beam 150 on the base 300. In this way, the balance of the top cap 110 side can be improved by the limiting beam 150, and the operation stability of the cap assembly 100 can be improved; the movable hole 151 provided thereon penetrates the limiting beam 150 along its thickness direction, and its bottom surface abuts against the top of the protective cover 140. In this way, the position of the protective cover 140 can be limited to prevent it from being separated from the balance beam 130. It should be explained that the thickness direction of the limiting beam 150 is in the same direction as the pressing direction Z.

[0045] In one example, a mounting groove is provided on the limiting beam 150, the mounting groove is arranged toward the top cap 110, the movable hole 151 penetrates the limiting beam 150 from the bottom of the mounting groove, and the top cap 110 is arranged in the mounting groove. In this way, the thickness space of the limiting beam 150 can be fully utilized, at least the occupied space of the cap body assembly 100 in the thickness direction of the limiting beam 150 is reduced, so that the vertical layout of the entire cap body assembly 100 is compact, which is conducive to miniaturization.

[0046] See also Figure 5In a possible implementation, the top cap 110 includes a main body 111, a connecting fold 112 and a sleeve 113. The connecting fold 112 is arranged around the periphery of the main body 111 facing the support column 120. The sleeve 113 is arranged on the main body 111 and on the same side as the connecting fold 112. The support column 120 is inserted into the sleeve 113.

[0047] In this embodiment, the specific configuration of the top cap 110 is optimized. Specifically, the body 111 is configured as a composite component including at least the body 111, the connecting fold 112 and the sleeve 113. The body 111 can be a thick plate-like structure that is approximately square; the connecting fold 112 can be a strip-like structure that is enclosed to form a circle, which is protrudingly configured on the periphery of the body 111 and enclosed with the body 111 to form a mounting groove; the sleeve 113 is configured in the mounting groove, and a limiting hole is provided on the sleeve 113, and the top end of the support column 120 is inserted into the limiting hole to prevent the support column 120 from moving on the body 111, thereby improving the connection stability between the top cap 110 and the support column 120.
