After the end of the elastic member connected to the toggle member moves to the other side of the movable contact arm, the elastic member can drive the free end of the movable contact arm to rotate quickly with a large elastic force, so that the free end of the movable contact arm rotates quickly, that is, rotates from the off position to the on position, and the switch mechanism becomes the on state. Since the position switching speed of the movable contact arm is very fast, the arcing time that may occur at the movable contact arm is very short, which effectively reduces arc erosion.

[0060] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0061] The embodiment of the present disclosure provides a switch mechanism, Figure 1 is a schematic diagram of the switch mechanism, see Figure 1 The switch mechanism includes a support base 10, a toggle member 20, a movable contact arm 30 and an elastic member 40.

[0062] The fixed end of the toggle member 20 abuts against the support seat 10, and the free end of the toggle member 20 can rotate relative to the support seat 10. The fixed end of the movable contact arm 30 abuts against the support seat 10, and the free end of the movable contact arm 30 can rotate relative to the support seat 10, and the rotation axis of the movable contact arm 30 is parallel to the rotation axis of the toggle member 20. The two ends of the elastic member 40 are respectively connected to the toggle member 20 and the movable contact arm 30, and are in a stretched state.

[0063] The switch mechanism is configured such that when the free end of the toggle member 20 is subjected to an external force and rotates, the free end of the movable contact arm 30 is driven to rotate from the off position to the on position through the elastic member 40 .

[0064] Figure 2 is a schematic diagram of the position change of the elastic member 40, combined with Figure 2 , in the off state, the position of the elastic member 40 is Figure 2 As shown on the upper side, in the switched-on state, the position of the elastic member 40 is Figure 2 Shown below.

[0065] At the beginning of the rotation of the free end of the toggle member 20 under the action of external force, the end of the elastic member 40 connected to the toggle member 20 moves to one side of the movable contact arm 30, and the movable contact arm 30 remains stationary, so that the elastic member 40 is further stretched by the rotating toggle member 20 and accumulates elastic potential energy. After the end of the elastic member 40 connected to the toggle member 20 moves to the other side of the movable contact arm 30, the elastic member 40 can drive the free end of the movable contact arm 30 to rotate quickly with a large elastic force, that is, rotate from the off position to the on position, and the switch mechanism becomes the on state. Since the position switching speed of the movable contact arm 30 is very fast, the arcing time that may occur at the movable contact arm 30 is very short, which effectively reduces arc ablation.

[0066] When the external force disappears, the toggle member 20, the movable contact arm 30 and the elastic member 40 move in the opposite direction, and the free end of the movable contact arm 30 rotates rapidly, that is, rotates from the on position to the off position, and the switch mechanism changes to the off state. In this process, the arcing time that may occur at the movable contact arm 30 is very short, which effectively reduces arc erosion.

[0067] In this embodiment, the elastic member 40 is a long strip structure. When the free end of the movable contact arm 30 switches between the off position and the on position, the end of the elastic member 40 connected to the toggle member 20 moves from one side of the movable contact arm 30 to the other side.

[0068] Exemplarily, the elastic member 40 is a coil spring.

[0069] In this embodiment, the rotation axis of the toggle member 20 is close to the free end of the movable contact arm 30 , and the rotation axis of the movable contact arm 30 is close to the free end of the toggle member 20 .

[0070] In the above implementation, the rotation axis of the toggle member 20 is close to the free end of the movable contact arm 30, that is, close to the connection between the elastic member 40 and the movable contact arm 30, so that the force arm when the toggle member 20 rotates can be effectively increased, thereby ensuring that the toggle member 20 can apply sufficient force to the movable contact arm 30. The rotation axis of the movable contact arm 30 is close to the free end of the toggle member 20, that is, close to the connection between the toggle member 20 and the movable contact arm 30, so that when the rotation angle of the movable contact arm 30 remains unchanged, the rotation amplitude of the free end of the movable contact arm 30 is increased, which is conducive to the free end of the movable contact arm 30 contacting or separating with the charged device.

[0071] As the toggle member 20 rotates, it drives the elastic member 40 to move relative to the moving contact arm 30, that is, one end of the elastic member 40 connected to the toggle member 20 moves from one side of the moving contact arm 30 to the other side, so it is necessary to provide a moving space for the elastic member 40. In this embodiment, the moving contact arm 30 has a notch 310 at one end facing the support seat 10, and the elastic member 40 is movably located in the notch 310.

[0072] The notch 310 provides sufficient space for the elastic member 40 to move, thereby preventing the elastic member 40 from interfering with or colliding with the movable contact arm 30 when the elastic member 40 moves.

[0073] See again Figure 1 In this embodiment, the support seat 10 includes a first support plate 121 and a second support plate 122, and an angle is formed between the first support plate 121 and the second support plate 122. One end of the first support plate 121 is connected to one end of the second support plate 122. The toggle member 20 abuts against the second support plate 122, and the movable contact arm 30 abuts against the first support plate 121.

[0074] In the above implementation, the first support plate 121 is used to provide a support base for the movable contact arm 30 so that the movable contact arm 30 can rotate relative to the support base 10, and the second support plate 122 is used to provide a support base for the toggle member 20 so that the movable contact arm 30 can rotate relative to the support base 10.

[0075] Exemplarily, the support base 10 is an integrated copper structure, which can not only ensure the structural integrity of the support base 10 but also improve the manufacturing efficiency of the support base 10 .

[0076] See again Figure 1 Exemplarily, the second support plate 122 has a socket 123 , and the fixed end of the toggle member 20 has a protrusion 210 , which can be movably inserted into the socket 123 .

[0077] In the above implementation, the fixed end of the toggle member 20 can be firmly abutted against the second support plate 122 through the cooperation between the socket 123 and the protrusion 210, thereby preventing the toggle member 20 from falling off the second support plate 122 during rotation.

[0078] Exemplarily, the second support plate 122 has two sockets 123, and the two sockets 123 are respectively located on opposite sides of the second support plate 122. The fixed end of the toggle member 20 has two protrusions 210, and the two protrusions 210 are spaced apart from each other, and the protrusions 210 correspond to the sockets 123 one by one, and the protrusions 210 are respectively inserted into the corresponding sockets 123. The second support plate 122 between the two sockets 123 and the toggle member 20 between the two protrusions 210 abut against each other.

[0079] In the above implementation, by providing two sockets 123 and two protrusions 210 , the assembly firmness between the toggle member 20 and the second support plate 122 can be effectively improved.

[0080] See again Figure 1 In this embodiment, a side of the first support plate 121 facing away from the second support plate 122 has a buckle 124 , and the fixed end of the movable contact arm 30 can be movably inserted into the buckle 124 .

[0081] In the above implementation, the fixed end of the movable contact arm 30 can be firmly abutted against the first support plate 121 through the mutual cooperation between the buckle 124 and the fixed end of the movable contact arm 30, thereby preventing the movable contact arm 30 from falling off the first support plate 121 during rotation.

[0082] Exemplarily, the first support plate 121 has two buckles 124 , which are spaced apart from each other, and the fixed ends of the movable contact arm 30 are respectively inserted into the two buckles 124 , thereby further improving the assembly firmness between the movable contact arm 30 and the first support plate 121 .

[0083] The embodiment of the present disclosure provides a socket assembly, Figure 3 is a structural schematic diagram of the socket assembly, Figure 3 for Figure 1 The upward perspective, combined with Figure 3In this embodiment, the plug assembly includes a plug clip 110 and Figure 1 and 2 The switch mechanism shown.

[0084] The socket clip 110 is connected to the support base 10 . When the socket assembly is in a power-off state, the free end of the toggle member 20 is opposite to the socket opening 114 of the socket clip 110 .

[0085] In the above implementation, the plug sleeve clamp 110 is used to receive and insert the plug pin 1000, and after the plug is inserted, the plug pin 1000 is clamped to prevent the plug pin 1000 from falling out, that is, to ensure that the plug pin 1000 stops the toggle member 20. The support seat 10 is used to support the toggle member 20 and the movable contact arm 30, providing a basis for the rotation of the toggle member 20 and the movable contact arm 30. In addition, since the toggle member 20 and the movable contact arm 30 are located on opposite sides of the support seat 10, the rotation of the two will not interfere with each other, thereby improving the reliability of the working of the plug sleeve assembly.

[0086] Figures 4 to 6 It is a schematic diagram of the state of the plug-in assembly, combined with Figures 4 to 6 The working process of the socket assembly is introduced. It should be noted that in order to show the insertion of the pin 1000, Figures 4 to 6 The plug sleeve clip 110 is partially cut away.

[0087] During the process of plug insertion, the plug pin 1000 of the plug will first be inserted into the plug sleeve clip 110, but at this time, the movable contact arm 30 and the connecting terminal 100 are not in contact (see Figure 4 ), so the socket clip 110 is not electrified, and arcing will not occur between the pin 1000 and the socket clip 110.

[0088] As the plug pin 1000 is further inserted, the plug pin 1000 contacts the free end of the toggle member 20 and applies an external force to the free end of the toggle member 20, so that the free end of the toggle member 20 rotates, and the free end of the movable contact arm 30 is driven to rotate through the elastic member 40 until the free end of the movable contact arm 30 contacts the connection terminal 100 of the socket, and the socket assembly becomes energized, and the plug pin 1000 is energized accordingly (see Figure 5 ). Moreover, under the action of the elastic member 40, the movable contact arm 30 and the toggle member 20 always have a tendency to reset, but because the pin 1000 remains inserted into the socket clip 110, the toggle member 20 can be stopped, thereby maintaining the position of the movable contact arm 30 so that it remains in contact with the terminal 100.

[0089] During the process of pulling out the plug, the plug pin 1000 will first release the stopper for the toggle member 20, and the plug pin 1000 is still located in the plug sleeve clip 110 (see Figure 4). Under the action of the elastic member 40, the movable contact arm 30 and the toggle member 20 begin to reset, and the free end of the movable contact arm 30 no longer contacts the terminal 100, and the socket assembly becomes de-energized, and the pin 1000 loses power accordingly. However, since the pin 1000 has not been pulled out of the socket clip 110 at this time, there is naturally no arcing phenomenon between the pin 1000 and the socket clip 110.

[0090] As the pin 1000 is continuously pulled out, the movable contact arm 30 and the toggle member 20 are completely reset, waiting for the next insertion of the pin 1000 (see Figure 6 ).

[0091] That is to say, the socket assembly provided in the embodiment of the present disclosure effectively avoids arcing between the pin 1000 and the socket clip 110 by "inserting first and then getting power" and "losing power first and then unplugging", thereby avoiding the problem of arc erosion.

[0092] It is worth noting that “insert first, then power on” means that the pin 1000 is first inserted into the socket clip 110 and then the socket clip 110 is powered on. “lose power first, then unplug” means that the socket clip 110 loses power first and then the pin 1000 is unplugged.

[0093] In this embodiment, the first support plate 121, the second support plate 122 and the plug sleeve clip 110 form a Z-shaped structure, the toggle member 20 rotates within the angle space formed by the first support plate 121 and the second support plate 122, and the movable contact arm 30 rotates within the angle space formed by the first support plate 121 and the plug sleeve clip 110, so that the rotation of the toggle member 20 and the movable contact arm 30 will not interfere with each other, thereby improving the reliability of the working of the plug sleeve assembly.

[0094] See again Figure 3 In this embodiment, the sleeve clamp 110 includes a stationary clamp arm 111 and a movable clamp arm 112. One end of the stationary clamp arm 111 is connected to one end of the movable clamp arm 112, and the stationary clamp arm 111 and the movable clamp arm 112 are arranged opposite to each other to form a sleeve opening 114 between the stationary clamp arm 111 and the movable clamp arm 112.

[0095] In the above implementation, since the free end of the toggle member 20 is located at the gap between the static clamp arm 111 and the dynamic clamp arm 112 when the socket assembly is in the power-off state, when the pin 1000 is inserted into the socket clamp 110 through the socket opening 114, that is, the gap between the static clamp arm 111 and the dynamic clamp arm 112, the pin 1000 can push the free end of the toggle member 20 and apply external force to the free end of the toggle member 20, so that the free end of the toggle member 20 rotates.

[0096] Since the toggle member 20 and the moving contact arm 30 are respectively located on opposite sides of the support base 10, in order to facilitate the elastic member 40 to be respectively connected to the toggle member 20 and the moving contact arm 30, in this embodiment, the static clamp arm 111 has a through hole 113, and the free end of the toggle member 20 has a connecting arm 220, which is movably located in the through hole 113 and connected to the elastic member 40.

[0097] In the above implementation, one end of the connecting arm 220 passes through the through hole 113, so as to be connected to the elastic member 40. In addition, since the connecting arm 220 is movably located in the through hole 113, the rotation of the toggle member 20 is not hindered.

[0098] In the power-off state, the connecting arm 220 is bent toward the movable contact arm 30 , so that the connecting arm 220 can be closer to the movable contact arm 30 , so that the elastic member 40 can connect the connecting arm 220 and the movable contact arm 30 respectively.

[0099] In addition, in the power-off state, part of the connecting arm 220 is located in the gap between the static clamp arm 111 and the dynamic clamp arm 112, and the connecting arm 220 is inclined to the plug-in direction of the plug pin 1000. In this way, after the plug pin 1000 is inserted into the plug sleeve clamp 110, it will abut against the connecting arm 220, and as the plug pin 1000 continues to be inserted, the plug pin 1000 and the connecting arm 220 slide against each other until the plug pin 1000 and the connecting arm 220 are parallel to each other. At this time, the toggle member 20 rotates into place, and the connecting arm 220 and the plug pin 1000 are parallel to each other, so that the plug pin 1000 firmly stops the toggle member 20.

[0100] Since arcing may occur between the movable contact arm 30 and the terminal 100, after the socket assembly is used for a long time, adhesion may occur between the movable contact arm 30 and the terminal 100 due to arc erosion, resulting in the movable contact arm 30 and the terminal 100 being unable to be separated under the action of the elastic member 40. To solve this problem, in this embodiment, a push arm 320 is provided at the fixed end of the movable contact arm 30, and the length direction of the push arm 320 is consistent with the length direction of the movable contact arm 30. The end of the push arm 320 away from the movable contact arm 30 has an inclined surface 321, and the inclined surface 321 is opposite to the movable clamp arm 112.

[0101] After the pin 1000 is pulled out of the gap between the stationary clamp arm 111 and the movable clamp arm 112, the movable clamp arm 112 will move toward the stationary clamp arm 111 to reset. If the movable contact arm 30 can be normally separated from the terminal 100 under the action of the elastic member 40, the reset movable clamp arm 112 will not contact the push arm 320. If the movable contact arm 30 and the terminal 100 are adhered together due to arc erosion and cannot be separated under the action of the elastic member 40, the reset movable clamp arm 112 will hit the inclined surface 321 of the push arm 320, thereby driving the movable contact arm 30 to rotate, so that the movable contact arm 30 and the terminal 100 are forcibly separated.

[0102] Figure 7 A schematic diagram of a socket structure provided by an embodiment of the present disclosure is shown in FIG. Figure 7 In this embodiment, the socket includes a housing 200 and Figures 3 to 6 As shown, the socket assembly 300 is located inside the housing 200 .

[0103] Since the socket includes Figures 3 to 6 The socket assembly 300 shown in FIG. Figures 3 to 6 All the beneficial effects of the illustrated socket assembly 300 are not described in detail here.

[0104] In this embodiment, the housing 200 includes a panel 2100, a cover plate 2200 and a rear cover 2300. The cover plate 2200 covers the opening of the rear cover 2300, and the panel 2100 covers the side of the cover plate 2200 facing away from the rear cover 2300. The socket assembly 300 is located in the rear cover 2300, and a limiting column is provided on the side of the cover plate 2200 facing the rear cover 2300. When the socket assembly 300 is in a power-off state, the limiting column abuts against the free end of the movable contact arm 30 to limit the position of the free end of the movable contact arm 30.
