[0025] Embodiment
[0026] Please refer to Figures 1-5 , this embodiment provides a socket based on a lever structure, including: a housing, the housing includes an installation groove 2 and a cover plate 1, the cover plate 1 covers the installation groove 2, and a receiving space is formed between the cover plate 1 and the installation groove 2, and a jack 3 for plug insertion is opened on the cover plate 1; a contact system, the contact system includes a stationary piece 4 connected to an energized wire and a movable piece mechanism connected to the socket, the stationary piece 4 is fixed on the cover plate 1, the movable piece mechanism includes a socket clip 5, a current - connecting slider 6 and a connecting rod 7, the socket clip 5 is arranged on the cover plate 1, and the opening of the socket clip 5 corresponds to the jack 3, the current - connecting slider 6 is slidably arranged on the socket clip 5, one end of the connecting rod 7 is hinged to the current - connecting slider 6, a support 8 is arranged on the cover plate, the connecting rod 7 is rotatably connected to the support 8, and the end of the connecting rod 7 away from the current - connecting slider 6 can abut against the stationary piece 4, and the current - connecting slider 6 is used to drive the connecting rod 7 to rotate around the support 8 and then abut against the stationary piece 4.
[0027] In this embodiment, the above - mentioned housing is used to protect the contact system installed in the housing, which can effectively protect the internal electrical components and extend their service life. Specifically, the above - mentioned installation groove 2 is used to cooperate with the cover plate 1 to form a closed receiving space, which can effectively prevent the arc from overflowing and reduce the entry of dust. The above - mentioned jack 3 is used for plug insertion, so that the plug - in piece is connected to the power after contacting the contact system.
[0028] In this embodiment, the above contact system is used to form a closed circuit after the plug is in contact, providing continuous electrical energy for the electrical appliance. Specifically, the above connecting rod 7 cooperates with the support 8 to form a lever structure within the housing structure. The above lever structure is a force-consuming lever, which drives the electricity-connecting slider 6 to move through a small distance, driving the other end of the connecting rod 7 to quickly abut against the static piece 4 that is always energized, causing the arc position to shift to the contact position between the connecting rod 7 and the static piece 4, and no arc is generated at the part where the plug directly contacts the socket clip 5, which can effectively protect the plug and extend the service life of the plug.
[0029] Please refer to Figure 1 and Figure 2 , in some embodiments of this embodiment, a return spring 9 for driving the separation of the connecting rod 7 and the static piece 4 is provided between the electricity-connecting slider 6 and the socket clip 5. The two ends of the return spring 9 are respectively connected to the electricity-connecting slider 6 and the socket clip 5.
[0030] In this embodiment, the above return spring 9 is used to drive the above connecting rod 7 to reset, avoiding continuous contact and electricity connection between the connecting rod 7 and the static piece 4 of the socket, which may cause an arc to be generated at the plug part during the second insertion. When the circuit is connected, due to the clamping force of the socket clip 5, it can ensure that the spring can be continuously in an extended state, ensuring the stability of the plug inserted into the socket.
[0031] Please refer to Figures 1-4 , in some embodiments of this embodiment, a conductive platform 10 is provided at one end of the connecting rod 7 away from the electricity-connecting slider 6, a convex platform 11 connected to the conductive platform 10 is provided on the static piece 4, and a limiting member 13 is provided on the convex platform 11. The limiting member 13 includes a spring piece 1301 and a limiting block 1302. The spring piece 1301 is provided on the static piece 4, the limiting block 1302 is provided on the static piece 4, and a limiting space for accommodating the conductive platform 10 is formed between the limiting block 1302 and the convex platform 11, and the conductive platform 10 can push open the limiting block 1302 and enter the limiting space.
[0032] In this embodiment, the above-mentioned conductive platform 10 is used to form a closed-loop circuit after contacting the boss 11 on the stationary piece 4. The above-mentioned conductive platform 10 is used to increase the contact area between the connecting rod 7 and the boss 11, which can reduce the generation of electric arcs; there is a contact surface on the above-mentioned boss 11 that is adapted to the above-mentioned conductive platform 10, and a stable closed-loop circuit is formed after the two come into contact. The above-mentioned limiting member 13 is used to store energy during insertion, so that the conductive platform 10 can quickly contact and connect with the energized boss 11 after storing energy. Specifically, the elastic piece 1301 of the above-mentioned limiting member 13 has a certain elasticity. When the conductive platform 10 moves to the limiting block 1302, the limiting block 1302 is located on the path of the conductive platform 10 towards the boss 11, increasing the pressure to push the conductive platform 10. The elastic piece 1301 bends outward in the radial direction of the boss 11. When the elastic piece 1301 bends until the limiting block 1302 moves out of the path of the conductive platform 10 towards the boss 11, the above-mentioned conductive block and the boss 11 are quickly attached and connected, and the elastic piece 1301 resets, fixing the conductive platform 10 in the limiting space; when the socket is pulled out, due to the existence of the spring force and the disappearance of the force provided by the socket clip 5, the conductive block drives the elastic piece 1301 to bend until the limiting block 1302 moves out of the path of the conductive platform 10 towards the boss 11, and the boss 11 and the conductive block are quickly separated.
[0033] Please refer to Figures 1-4 , in some implementation manners of this embodiment, a first chamfer structure 12 is provided on the above-mentioned limiting block 1302, and a second chamfer structure 14 is provided on the surface of the conductive platform 10 that abuts against the boss 11, and the second chamfer structure 14 can abut against the first chamfer structure 12.
[0034] In this embodiment, the above-mentioned first chamfer and the second chamfer structure 14 cooperate with each other to facilitate the decomposition of the vertical thrust, and facilitate driving the elastic piece 1301 to bend to form a path for the conductive platform 10 to pass through. One end of the above-mentioned conductive platform 10 away from the boss 11 is a conical platform structure, which is convenient for the lower chamfer of the limiting block 1302 to decompose the pulling force when the conductive platform 10 and the boss 11 are separated, and is convenient for the reset of the conductive block.
[0035] During use, the plug enters the socket through the jack 3, the contact piece of the plug extends into the socket clip 5, the contact piece of the plug pushes the power connection slider 6 to move, and the movement of the power connection slider 6 drives the connecting rod 7 to rotate around the support 8. At the same time, the return spring 9 is continuously stretched. When one end of the connecting rod 7 away from the power connection slider 6 abuts against the first chamfer structure 12 on the limiting block 1302, with the application of pressure, the elastic piece 1301 moves along a direction perpendicular to the axis of the boss 11. When the movement reaches the point where the movement path of the conductive platform 10 is unobstructed, the conductive platform 10 can quickly abut against the surface of the boss 11.
[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
