[0049] 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.
[0050] The present disclosure provides a switch. Figure 1 For a schematic diagram of the switch structure, see Figure 1 In this embodiment, the switch includes a housing 100 and a stationary contact structure 200. The stationary contact structure 200 is located inside the housing 100.
[0051] Figure 2 It is a schematic diagram of the structure of the static contact piece. Figure 2 The stationary contact structure 200 includes a contact 10 and an elastic member 20 , one end of the contact 10 is a contact end 110 , one end of the elastic member 20 is connected to the contact 10 , and the other end of the elastic member 20 is connected to the housing 100 .
[0052] One end of the contact piece 10 is a contact end 110, and the contact end 110 is used to contact the moving contact piece structure 300 in the switch, so as to realize the connection of the switch. When the contact end 110 is subjected to external force due to the collision of the moving contact piece structure 300, since the contact piece 10 is connected to the elastic member 20, the external force exerted on the moving contact piece structure 300 can be transmitted to the elastic member 20, so that the elastic member 20 produces elastic deformation, thereby absorbing a part of the external force exerted on the contact end 110. In addition, since the elastic member 20 is connected to the inner wall of the shell 100, the remaining external force exerted on the other part of the contact end 110 can be transmitted to the shell 100 through the elastic member 20 to be quickly dissipated. In this way, by arranging the elastic member 20 between the contact piece 10 and the shell 100, the bounce of the contact piece 10 can be effectively eliminated.
[0053] That is to say, the elastic member 20 can eliminate the bounce of the contact piece 10, thereby avoiding arcing at the contact end 110, and further avoiding problems such as arc erosion.
[0054] In this embodiment, the housing 100 includes an outer shell and a mounting frame 1200 . The mounting frame 1200 is located inside the outer shell. Both the outer shell and the mounting frame 1200 are insulating members. The elastic member 20 is directly connected to at least one of the outer shell and the mounting frame 1200 .
[0055] In the above implementation, the housing and the mounting bracket 1200 together form the housing 100. There are multiple ways to connect the elastic member 20 to the housing 100. For example, the elastic member 20 is connected to the inner wall of the housing, or the elastic member 20 is connected to the mounting bracket 1200 (see Figure 1 ), or the elastic member 20 is connected to the housing and the mounting frame 1200 respectively. The present disclosure does not limit the connection method of the elastic member 20 in the housing 100, and it only needs to ensure that the elastic member 20 can be stably installed in the housing 100.
[0056] It is worth noting that directly connected means that two components are directly connected together without any other components between them. In this embodiment, the elastic member 20 is directly connected to the housing 100, which is different from the elastic member in the related art that is indirectly connected to the housing through other components, such as terminals.
[0057] In addition, when the switch is configured in a socket, the mounting frame 1200 can be connected to the inner wall of the shell, or the mounting frame 1200 can be connected to the side of the socket pressure plate facing the shell, as long as the mounting frame 1200 is firmly located in the shell.
[0058] Figure 3 is a schematic diagram of the swing of the contact piece 10, combined with Figure 3 In this embodiment, the end of the contact piece 10 away from the contact end 110 is the wiring terminal 120, and the distance between the wiring terminal 120 and the swing axis of the contact piece 10 is smaller than the distance between the contact end 110 and the swing axis of the contact piece 10.
[0059] In the above implementation, the wiring terminal 120 and the contact terminal 110 are two opposite ends of the contact piece 10. The wiring terminal 120 is used to connect the wires, thereby realizing the electrical connection between the contact piece 10 and other parts.
[0060] When the contact end 110 of the contact piece 10 is subjected to an external force, the contact piece 10 will swing as a whole. In this process, the contact piece 10 is equivalent to a lever. Based on the lever principle, the terminal 120 that is closer to the swing axis has a smaller swing amplitude, while the contact end 110 that is farther from the swing axis has a larger swing amplitude. In this way, the smaller swing amplitude of the terminal 120 can ensure the stability of the connection between the wire and it, and avoid the wire being torn off due to the excessive swing amplitude of the terminal 120. The larger swing amplitude of the contact end 110 can make it fully compress the elastic member 20 under the action of external force, which is conducive to the elastic member 20 to better absorb the force to reduce the bounce of the contact piece 10.
[0061] In some examples, the terminal 120 is electrically connected to the wire. For example, the terminal 120 and the wire are connected by welding. Alternatively, a threading hole is provided on the terminal 120, and the wire is inserted into the threading hole, thereby achieving the connection between the terminal 120 and the wire. The present disclosure does not limit the connection method between the terminal 120 and the wire.
[0062] In other examples, the terminal 120 is electrically connected to the copper sheet 400 (see Figure 4 For example, the terminal 120 and the copper sheet 400 are connected by welding. Alternatively, the terminal 120 and the copper sheet 400 are an integrated structure, thereby omitting an assembly process and improving assembly efficiency.
[0063] See again Figure 2 In this embodiment, the elastic member 20 includes a spring sheet 210 and a fixing sheet 220 , one end of the spring sheet 210 is connected to the fixing sheet 220 , the other end of the spring sheet 210 is connected to the contact end 110 , and the length direction of the spring sheet 210 is consistent with the length direction of the contact sheet 10 .
[0064] In the above implementation, the fixing piece 220 is used to be fixedly connected to the housing 100, thereby providing a stable installation base for the spring piece 210. The spring piece 210 itself is elastic, and it is connected between the fixing piece 220 and the contact end 110, and can fully absorb the force applied by the contact end 110.
[0065] Exemplarily, the spring piece 210 and the fixing piece 220 are an integrated structural component, which not only ensures the structural strength of the elastic member 20 but also improves the manufacturing efficiency of the elastic member 20 .
[0066] Continue to see Figure 2 In this embodiment, the spring piece 210 includes a contact section 211 and a spacing section 212. The contact section 211 is attached to the contact piece 10, and the spacing section 212 is spaced apart from the contact piece 10 (see Figure 5), one end of the spacing segment 212 is connected to the contact segment 211, and the other end of the spacing segment 212 is connected to the fixing plate 220.
[0067] In the above implementation, the contact segment 211 and the contact piece 10 are close to each other, which can effectively ensure the contact area between the spring piece 210 and the contact piece 10. In this way, on the one hand, it can be conducive to the transmission of the force between the spring piece 210 and the contact piece 10, and on the other hand, it can ensure the assembly stability between the spring piece 210 and the contact piece 10. The spacing segment 212 and the contact piece 10 are spaced apart, which can provide sufficient space between the two during the swing of the contact piece 10 and the deformation of the spring piece 210 to avoid interference, thereby effectively improving the reliability of the static contact piece structure.
[0068] In this embodiment, the stationary contact piece structure further includes a contact 30 . The contact 30 is located at the contact end 110 , and the contact 30 is inserted into the contact piece 10 and the spring piece 210 at the same time.
[0069] In the above implementation, the contact 30 is used to contact the moving contact piece structure 300, thereby realizing electrical connection between the stationary contact piece structure and the moving contact piece structure 300. In addition, connecting the contact piece 10 and the spring piece 210 through the contact 30 can simplify the stationary contact piece structure and reduce manufacturing costs.
[0070] Exemplarily, the portion of the contact 30 that contacts the movable contact piece structure 300 is a silver structure.
[0071] Exemplarily, the contact 30 is riveted to the contact piece 10 and the spring piece 210 respectively.
[0072] In the above implementation, the contact 30 is connected to the contact piece 10 and the spring piece 210 respectively by riveting, which can ensure both the connection stability and the assembly efficiency.
[0073] Figure 6 This is the installation diagram of the static contact structure. Figure 6 In this embodiment, the fixing plate 220 has at least two mounting holes 221 , and the mounting holes 221 are spaced apart from each other. The mounting frame 1200 has at least two latches 1100 , and the latches 1100 correspond to the mounting holes 221 one by one, and the latches 1100 are inserted into the corresponding mounting holes 221 .
[0074] In the above implementation, the mounting hole 221 is used to accommodate the latch 1100 on the mounting frame 1200. When installing the stationary contact structure, the mounting hole 221 is sleeved outside the latch 1100 of the mounting frame 1200. Since the mounting holes 221 are spaced apart from each other, the fixing plate 220 can be positioned stably.
[0075] Exemplarily, the fixing plate 220 is a square structure, and the two mounting holes 221 are respectively located at two ends of a diagonal line of the fixing plate 220 .
[0076] Such a design can achieve effective positioning and installation of the fixing plate 220 .
[0077] During the swinging of the contact piece 10 , the spring piece 210 and the contact piece 10 swing together, but the fixing piece 220 remains stationary. In this embodiment, the connection between the fixing piece 220 and the spring piece 210 is the swing axis of the contact piece 10 .
[0078] In the above implementation, since the fixing plate 220 is firmly connected to the housing 100, the connection between the fixing plate 220 and the spring 210 is set as the swing axis of the contact 10, which can ensure the swing stability of the contact 10, thereby improving the reliability of the stationary contact structure.
[0079] It is worth noting that both the spring sheet 210 and the fixing sheet 220 are sheet-like structural members, so the connection between the spring sheet 210 and the fixing sheet 220 is a linear fold, thereby matching the swing axis of the contact sheet 10 .
[0080] Figure 7 It is a side view of the static contact structure. Figure 7 and Figure 5 The difference lies in the elastic member 20. In this embodiment, the elastic member 20 is elastic soft rubber, the connection position between the elastic member 20 and the contact piece 10 is far away from the contact end 110, and the connection between the elastic member 20 and the contact piece 10 is the swing axis of the contact piece 10.
[0081] In the above implementation, the elastic member 20 is set to an elastic soft glue, which is elastic and can also produce elastic deformation and absorb the external force on the contact end 110, thereby effectively eliminating the bounce of the contact 10. In addition, since the contact 10 is directly connected to the housing 100 through the elastic member 20, the swing axis of the contact 10 is the connection between the elastic member 20 and the contact 10. Since the connection position between the elastic member 20 and the contact 10 is far away from the contact end 110, the terminal 120 can also have a smaller swing amplitude, which can ensure the stability of the connection between the wire and the terminal 120 and avoid being torn off due to excessive swing amplitude of the terminal 120. The larger swing amplitude of the contact end 110 can make it fully compress the elastic member 20 under the action of external force, which is conducive to the elastic member 20 to better absorb the force to reduce the bounce of the contact 10.
[0082] Figure 8 It is a side view of the static contact structure. Figure 8 and Figure 5The difference lies in the elastic member 20. In this embodiment, the elastic member 20 is a spring, the connection position between the elastic member 20 and the contact piece 10 is far away from the contact end 110, and the connection between the elastic member 20 and the contact piece 10 is the swing axis of the contact piece 10.
[0083] In the above implementation, the elastic member 20 is set as a spring, which is elastic and can also produce elastic deformation and absorb the external force on the contact end 110, thereby effectively eliminating the bounce of the contact 10. In addition, since the contact 10 is directly connected to the housing 100 through the elastic member 20, the swing axis of the contact 10 is the connection between the elastic member 20 and the contact 10. Since the connection position between the elastic member 20 and the contact 10 is far away from the contact end 110, the terminal 120 can also have a smaller swing amplitude, which can ensure the stability of the wire connection therewith and avoid breaking due to excessive swing amplitude of the terminal 120. The larger swing amplitude of the contact end 110 can make it fully compress the elastic member 20 under the action of external force, which is conducive to the elastic member 20 to better absorb the force to reduce the bounce of the contact 10.
[0084] The present invention provides a socket, which includes a socket power supply unit and a Figures 1 to 8 The switch shown is used to control the power on and off of the power supply of the socket.
[0085] Since the socket includes Figures 1 to 8 The switch shown, so the socket has Figures 1 to 8 All the beneficial effects of the switch shown will not be repeated here.
[0086] In this embodiment, the power socket is used to receive the plug of the electrical appliance. By turning on the switch, the power socket can be powered on, so that the electrical appliance can be powered. Conversely, by turning off the switch, the power socket can be powered off, so that the electrical appliance loses power.
