[0059] Unless otherwise defined, all technical terms used in the embodiments of the present utility model have the same meanings as those commonly understood by those of ordinary skill in the art.

[0060] To make the objectives, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.

[0061] On the one hand, as shown in Figure 1 this embodiment provides a switching device, which includes a moving contact piece 1, a static contact piece 2, a housing assembly 3 and a button assembly 4.

[0062] The moving contact piece 1 and the static contact piece 2 are respectively located inside the housing assembly 3, and there is a contact space 001 between the moving contact piece 1 and the static contact piece 2; the button assembly 4 is in pressing contact with the moving contact piece 1.

[0063] At least one of the moving contact piece 1 and the static contact piece 2 is provided with a ventilation structure 21.

[0064] In the switching device of this embodiment, at least one of the moving contact piece 1 and the static contact piece 2 is provided with a ventilation structure 21. The ventilation structure 21 can connect the contact space 001 between the two contact pieces with the external space, and can discharge substances such as metal vapor and carbonized dust generated by arc discharge in the contact space 001 to the outside, ensuring the insulation performance of the contact space 001, preventing abnormal conduction, and making the switching device have better reliability and safety.

[0065] Exemplarily, the button assembly 4 is located on the side of the moving contact piece 1 facing away from the contact space 001. The button assembly 4 can be used to drive the moving contact piece 1 to approach or move away from the static contact piece 2, so that the contact structure 5 in the moving contact piece 1 and the static contact piece 2 can be conducted or disconnected, realizing the on-off of the switching device.

[0066] As shown in Figure 1 in some embodiments, contact structures 5 are respectively provided on the surfaces of the moving contact piece 1 and the static contact piece 2 facing the contact space 001, and the ventilation structure 21 is located on the moving contact piece 1 or the static contact piece 2 on the periphery of the contact structure 5.

[0067] Since the arc releases metal vapor to the surrounding with the contact structure 5 as the center, and the ventilation structure 21 is arranged on the periphery of the contact structure 5, which is closer to the arc and corresponds to the dense area of metal vapor and carbonized dust, the effect of discharging metal vapor and carbonized dust is better.

[0068] In some possible implementation manners, the ventilation structure 21 is located on the moving contact piece 1, and the ventilation structure 21 communicates the contact space 001 with the space outside the moving contact piece 1. Alternatively, the ventilation structure 21 is located on the static contact piece 2, and the ventilation structure 21 communicates the contact structure 5 with the space outside the static contact piece 2. Or, ventilation structures 21 are provided on both the moving contact piece 1 and the static contact piece 2. The contact space 001 is communicated with the space outside the moving contact piece 1 by means of the ventilation structure 21 on the moving contact piece 1, and the contact space 001 is communicated with the space outside the static contact piece 2 by means of the ventilation structure 21 on the static contact piece 2.

[0069] Combined with Figure 2 As shown, in some embodiments, the ventilation structure 21 includes a through-hole structure 211, and the through-hole structure 211 penetrates the moving contact piece 1 or the static contact piece 2 in the thickness direction. Using the through-hole structure 211 that penetrates the moving contact piece 1 or the static contact piece 2 as the ventilation structure 21, the contact space 001 can be conducted to the outside space, and metal vapor, carbonized dust, etc. can be discharged.

[0070] Exemplarily, the through-hole structure 211 can be arranged in the middle of the moving contact piece 1 and the static contact piece 2.

[0071] Combined with Figure 2 As shown, in some embodiments, the ventilation structure 21 includes a notch groove structure 212, and the notch groove structure 212 is located at the edge of the moving contact piece 1 or the static contact piece 2 and is recessed toward the inside of the moving contact piece 1 or the static contact piece 2. Using the notch groove structure 212 at the edge of the moving contact piece 1 or the static contact piece 2 as the ventilation structure 21, the contact space 001 can be conducted to the outside space at the edge of the moving contact piece 1 or the static contact piece 2, and metal vapor, carbonized dust, etc. can be discharged.

[0072] Exemplarily, the notch groove structure 212 can be arranged at any edge of the moving contact piece 1 and the static contact piece 2 on the periphery of the contact structure 5.

[0073] Combined with Figure 3 As shown, in some embodiments, the trajectory along which the moving contact piece 1 drives the contact structure 5 to move is an arc trajectory 002, and the arc trajectory 002 has an axis 003. The ventilation structure 21 is located on at least one of a first side 501 of the contact structure 5 close to the axis 003 and a second side 502 of the contact structure 5 far from the axis 003.

[0074] In this embodiment, the moving contact piece 1 moves along the arc trajectory 002 to contact or separate from the static contact piece 2, so as to realize the on-off of the switching device. The movement trajectory of the contact structure 5 in the moving contact piece 1 will affect the direction of the arc. Therefore, the position of the ventilation structure 21 can be determined according to the movement trajectory of the moving contact piece 1, so that the ventilation structure 21 is arranged in the direction where the arc is concentrated or the arc moves, which is beneficial to improving the discharge effect of the ventilation structure 21 on metal vapor and carbonized dust. Refer to Figure 3, when the moving contact piece 1 moves along the arc trajectory 002, the projection position of the contact structure 5 of the moving contact piece 1 on the static contact piece 2 is located on the first side 501 of the contact structure 5 of the static contact piece 2. Thus, the arc between the two contact structures 5 mostly concentrates on the first side 501 and the second side 502 of the contact structure 5. Therefore, arranging the ventilation structure 21 preferably at the above two positions can effectively improve the derivation efficiency of the metal vapor.

[0075] Exemplarily, the ventilation structure 21 is located on the first side 501 of the contact structure 5; or, the ventilation structure 21 is located on the second side 502 of the contact structure 5; or, ventilation structures 21 are respectively provided on the first side 501 and the second side 502 of the contact structure 5.

[0076] In some possible implementation manners, referring to Figure 3 as shown, the moving contact piece 1 includes a second wiring portion 11, a second fixing portion 12, and a second bending portion 13. Among them, the second fixing portion 12 is connected to the housing assembly 3, the second wiring portion 11 is respectively connected to the second fixing portion 12, and the second wiring portion 11 extends to the outside of the housing assembly 3; the first end of the second bending portion 13 is elastically connected to the second fixing portion 12, the second end of the second bending portion 13 extends above the static contact piece 2, the contact structure 5 is located at the second end of the second bending portion 13, and the contact space 001 is surrounded by the second bending portion 13 and the static contact piece 2.

[0077] The button assembly 4 is pressed against the side of the second bending portion 13 facing away from the contact space 001. When the button assembly 4 presses the second bending portion, the second bending portion 13 can elastically deform around the first end, and the second end of the second bending portion 13 and the contact structure 5 thereon move along the arc trajectory 002.

[0078] Combined with Figure 4 as shown, in some embodiments, the ventilation structure 21 includes a through-hole structure 211 and a notch groove structure 212; the through-hole structure 211 is located on the moving contact piece 1 or the static contact piece 2 corresponding to the first side 501, and the notch groove structure 212 is located on the edge of the moving contact piece 1 or the static contact piece 2 corresponding to the second side 502.

[0079] Through the above arrangement, a through-hole structure 211 is arranged on the first side 501 of the contact structure 5 of the moving contact piece 1 or the static contact piece 2 as a ventilation structure 21, and a notch groove structure 212 is arranged on the second side 502 of the contact structure 5 of the moving contact piece 1 or the static contact piece 2 as another ventilation structure 21. The two ventilation structures 21 can quickly derive the metal vapor and carbonized dust in the contact space 001 around the contact structure 5.

[0080] Combined with Figure 5 as shown, in some embodiments, the through-hole structure 211 is an oval hole, and the symmetry line 004 of the through-hole structure 211 along the length direction is located in the plane determined by the arc trajectory 002.

[0081] In this embodiment, the kidney-shaped hole, or the long slot hole, has a larger ventilation area. The length symmetry line 004 is located in the plane of the arc track 002, such that the position of the kidney-shaped hole exactly corresponds to the concentrated position of the metal vapor, which can further improve the effect of the through-hole structure 211 in guiding out the metal vapor.

[0082] Combined with Figure 6 As shown, in some embodiments, the housing assembly 3 includes a first ventilation chamber 31 and a first ventilation port 32.

[0083] The first ventilation chamber 31 is located inside the housing assembly 3 and on the side of the static contact piece 2 facing away from the contact space 001. The first ventilation port 32 is located on the surface of the housing assembly 3 and communicates with the first ventilation chamber 31.

[0084] The through-hole structure 211 is located on the static contact piece 2 corresponding to the first side 501. The first ventilation chamber 31 communicates with the contact space 001 through the through-hole structure 211, and the first ventilation chamber 31 communicates with the external air through the first ventilation port 32.

[0085] Through the above arrangement, in the scenario where the through-hole structure 211 is provided on the first side 501 of the contact structure 5 in the static contact piece 2, the first ventilation chamber 31 is arranged on the side of the static contact piece 2 facing away from the contact space 001. The contact space 001 and the first ventilation chamber 31 communicate through the through-hole structure 211. The metal vapor in the contact space 001 can be quickly guided into the first ventilation chamber 31. Moreover, in order to guide the metal vapor in the first ventilation chamber 31 to the outside of the housing assembly 3, a first ventilation port 32 is also arranged on the surface of the housing assembly 3. The first ventilation chamber 31 can further discharge the metal vapor to the outside of the housing assembly 3 through the first ventilation port 32, thereby completely discharging the metal vapor from the switching device.

[0086] It should be noted that in practical applications, the metal vapor may have a relatively high deposition rate. Therefore, after the metal vapor in the contact space 001 enters the first ventilation chamber 31, it may directly deposit on the inner wall of the first ventilation chamber 31, and the heat contained therein will be discharged outward in the form of hot air through the first ventilation port 32.

[0087] In some possible implementation manners, referring to Figure 6 As shown, the housing assembly 3 includes a top shell 35 and a bottom cover 36. The moving contact piece 1 and the static contact piece 2 are respectively connected to the bottom cover 36. The top shell 35 covers the bottom cover 36 from above, wrapping the moving contact piece 1 and the static contact piece 2 inside. The static contact piece 2 is below and the moving contact piece 1 is above, surrounding the above-mentioned contact space 001 up and down. The two sides of the contact space 001 respectively correspond to the side edges of the top shell 35 or the bottom cover 36.

[0088] The button assembly 4 is movably connected to the top cover. The bottom of the button assembly 4 abuts against the top surface of the moving contact piece 1. The button assembly 4 can press the moving contact piece 1 downward to approach the static contact piece 2, realizing the conduction between the moving contact piece 1 and the static contact piece 2.

[0089] Exemplarily, the first ventilation cavity 31 is located below the static contact piece 2 and can be formed by a recessed structure of the bottom cover 36 at the corresponding position.

[0090] In some other possible implementation manners, referring to Figure 6 As shown, the first ventilation port 32 is located on the side wall of the top cover, and the top of the first ventilation port 32 extends to the corresponding position of the contact space 001. Thus, the metal vapor and heat in the contact space 001 can also be directly discharged from the switch device through the first ventilation port 32.

[0091] Combined with Figure 7 and Figure 8 As shown, in some embodiments, the housing assembly 3 further includes a second ventilation cavity 33 and a second ventilation port 34.

[0092] The second ventilation cavity 33 is located inside the housing assembly 3 and on the side of the end of the static contact piece 2 corresponding to the second side 502 that is away from the contact space 001. The second ventilation port 34 is located on the surface of the housing assembly 3 and communicates with the second ventilation cavity 33.

[0093] The notch groove structure 212 is located on the edge of the end of the static contact piece 2 corresponding to the second side 502. The second ventilation cavity 33 communicates with the contact space 001 through the notch groove structure 212, and the second ventilation cavity 33 communicates with the external air through the second ventilation port 34.

[0094] Through the above arrangement, in the scenario where the notch groove structure 212 is provided on the second side 502 of the contact structure 5 in the static contact piece 2, the second ventilation cavity 33 is arranged on the side of the static contact piece 2 that is away from the contact space 001. The contact space 001 and the second ventilation cavity 33 are communicated through the through-hole structure 211. The metal vapor in the contact space 001 can be quickly led into the second ventilation cavity 33. Moreover, in order to discharge the metal vapor in the second ventilation cavity 33 to the outside of the housing assembly 3, the second ventilation port 34 is also arranged on the surface of the housing assembly 3. The second ventilation cavity 33 can further discharge the metal vapor to the outside of the housing assembly 3 through the second ventilation port 34, thereby completely discharging the metal vapor from the switch device.

[0095] In this embodiment, the first ventilation cavity 31 and the first ventilation port are used to exhaust the gas from the first side 501 of the contact structure 5 of the static contact piece 2, and the second ventilation cavity 33 and the second ventilation port 34 are used to exhaust the gas from the second side 502 of the contact structure 5 of the static contact piece 2. Thus, the metal vapor, carbonized dust, and heat generated by the arc in the contact space 001 can be exhausted, ensuring the air insulation in the contact space 001 and improving the safety and reliability of the switching device.

[0096] In some other possible implementation manners, referring to Figure 8 As shown in the figure, the second ventilation port 34 is located on the side wall of the top cover, and the top of the second ventilation port 34 extends to the corresponding position in the contact space 001. Thus, the metal vapor and heat in the contact space 001 can also be directly exhausted from the switching device through the second ventilation port 34.

[0097] In some embodiments, the first ventilation port 32 and the second ventilation port 34 are located on the side walls of the same side or different sides of the top cover. Exemplarily, the first ventilation port 32 and the second ventilation port 34 are located on the side walls of different sides of the top cover.

[0098] Combined with Figure 8 As shown in the figure, in some embodiments, the end of the static contact piece 2 corresponding to the second side 502 is arranged at an interval from the side wall of the second ventilation cavity 33.

[0099] In this embodiment, since the second ventilation cavity 33 corresponds to the end of the static contact piece 2 corresponding to the second side 502 at the same time, in order to prevent the plastic of the housing assembly 3 from being carbonized by the high temperature generated by the arc, the side wall of the second ventilation cavity 33 makes an interval avoidance of the end of the static contact piece 2. And after the side wall of the second ventilation cavity 33 makes an avoidance of the end of the static contact piece 2, it is also beneficial to increase the space of the second ventilation cavity 33, thereby being beneficial to improving the ventilation capacity between the second ventilation cavity 33 and the contact space 001.

[0100] Combined with Figure 9 As shown in the figure, in some embodiments, the static contact piece 2 includes a first wiring portion 22, a first fixing portion 23, and a first bending portion 24; the first fixing portion 23 is connected to the housing assembly 3, and the first wiring portion 22 and the first bending portion 24 are respectively connected to the first fixing portion 23; the first wiring portion 22 is located outside the housing assembly 3; the first bending portion 24 bends and protrudes toward the contact space 001, and the contact structure 5 is located on the surface of the first bending portion 24 facing the contact space 001.

[0101] Through the above arrangement, the contact structure 5 of the static contact piece 2 is arranged on the protruding first bending portion 24, which can make the contact structure 5 of the static contact piece 2 closer to the contact structure 5 of the moving contact piece 1, thereby ensuring a larger distance between the remaining part of the static contact piece 2 and the moving contact piece 1 and preventing arcing between the remaining part of the static contact piece 2 and the moving contact piece 1.

[0102] Combined Figure 10 and Figure 11 As shown, in some embodiments, the button assembly 4 includes a light-emitting element 41, a first conductive spring 42, a second conductive spring 43, and a contact piece 44. The contact piece 44 is located inside the housing assembly 3. The first electrode of the light-emitting element 41 is electrically connected to the moving contact 1 through the first conductive spring 42, and the second electrode of the light-emitting element 41 is electrically connected to the contact piece 44 through the second conductive spring 43.

[0103] With the above arrangement, the button assembly 4 can use the light-emitting element 41 to indicate the on / off state of the switching device. When the switching device is in the on state, that is, when the moving contact 1 and the static contact 2 are in contact and conducting, the first conductive spring 42 and the second conductive spring 43 supply power to the light-emitting element 41, causing the light-emitting element 41 to emit light. When the switching device is in the off state, that is, when the moving contact 1 and the static contact 2 are in contact and disconnected, the first conductive spring 42 and the second conductive spring 43 stop supplying power to the light-emitting element 41, and the light-emitting element 41 stops emitting light.

[0104] When the switching device of this embodiment works, the contact piece 44 will be connected to the neutral line 7, the live wire 6 access end connected to the static contact 2, and the live wire 6 outgoing end connected to the moving contact 1. When the switching device is in the on state, the moving contact 1 and the static contact 2 are in contact and conducting, and the live wire 6 - static contact 2 - moving contact 1 - first conductive spring 42 - light-emitting element 41 - second conductive spring 43 - contact piece 44 - neutral line 7 are sequentially conducting, and current flows through the light-emitting element 41 to achieve light emission. When the switching device is in the off state, the moving contact 1 and the static contact 2 are in contact and disconnected, the live wire 6 and the neutral line 7 cannot conduct, and there is no current in the light-emitting element 41.

[0105] Combined Figure 10 and Figure 11 As shown, in some embodiments, the button assembly 4 includes a button cap 45 and a telescopic locking mechanism 46. The button cap 45 is located on the side of the moving contact 1 facing away from the contact space 001, and one end of the telescopic locking mechanism 46 is connected to the button cap 45, and the other end presses against the surface of the moving contact 1 facing away from the contact space 001.

[0106] In this embodiment, when the button cap 45 is pressed down for the first time, the telescopic locking mechanism 46 can be locked in the pressed-down position, providing a continuous pressing force for the moving contact 1 to ensure the continuous conduction of the switching device. When the button cap 45 is pressed down again, the telescopic locking mechanism 46 is unlocked and moves upward, and the moving contact 1 loses the pressing force and bounces upward, and the switching device is disconnected.

[0107] Exemplarily, the light-emitting element 41 can be arranged inside the button cap 45, having a better on / off display effect.
