The contact resistance not only causes energy loss but also leads to problems such as softening and welding of the contact material during long-term operation, seriously affecting the reliability and service life of electrical contacts. At the same time, the generation of arcs will further exacerbate the wear of the contacts and even cause serious faults such as short circuits in the circuit. Summary of the Utility Model

[0026] Embodiment

[0027] Please refer to Figures 1-4 , this embodiment provides a spring-type quick-contact arc-reducing structure, including: a housing, the housing includes a rear seat 1 and a panel 2, the rear seat 1 is a groove structure, and the panel 2 covers the mouth of the groove structure; a contact system, the contact system includes a static piece 3 fixed in the rear seat 1 and a moving piece 4 slidably arranged in the rear seat 1, the moving piece 4 can abut against the static piece 3, a return spring 5 for driving the moving piece 4 to reset is arranged in the rear seat 1, and both ends of the return spring 5 are respectively connected to the rear seat 1 and the moving piece 4; an energy storage mechanism is further arranged between the moving piece 4 and the static piece 3, and the energy storage mechanism is used to store the kinetic energy required for the moving piece 4 to quickly impact the static piece 3.

[0028] In this embodiment, the above-mentioned housing is used to protect the internal components of the socket, and at the same time can also improve the overall strength and durability of the socket. The above-mentioned rear seat 1 is used to install the contact system and the energy storage mechanism, and the above-mentioned panel 2 is used to cooperate with the rear seat 1 to form a closed shell, which is convenient for each electrical contact part to work together.

[0029] In this embodiment, the above-mentioned contact system is used to connect and disconnect the circuit. Specifically, the above-mentioned moving piece 4 is used to contact and connect with the insertion piece of the plug and then connect with the static piece 3, which can avoid the direct connection between the plug and the live socket contact piece and avoid the generation of electric arcs to damage the plug. Further, the above-mentioned return spring 5 is used for the reset of the moving piece 4 after the plug is pulled out, and for driving the moving piece 4 to quickly separate from the static piece 3, improving the safety of use. The above-mentioned energy storage mechanism is located on the moving path of the moving piece 4 towards the static piece 3, and is used to block the movement of the moving piece 4 to store energy. When the stored kinetic energy is greater than the energy that can be blocked by the elasticity of the moving piece 4, the moving piece 4 crosses the energy storage mechanism and quickly impacts the static piece 3 to achieve electrical connection.

[0030] Please refer to Figures 2-4, in some embodiments of the present embodiment, the energy storage mechanism includes a mounting post 6 and an energy storage block 7. The energy storage block 7 is disposed at the end of the mounting post 6, and the moving piece 4 can abut against the energy storage block 7.

[0031] In the present embodiment, the mounting post 6 mounts the energy storage block 7. The energy storage block 7 is used to prevent the moving piece 4 from directly moving towards the static piece 3. When the moving piece 4 abuts against the top of the energy storage block 7, the moving piece 4 continuously obtains elastic potential energy. When the moving piece 4 bends, the path required for the moving piece 4 to move downward continuously shrinks. When the moving piece 4 moves past the energy storage block 7 and the movement path resumes, the elastic potential energy is released, and the moving piece 4 hits the static piece 3 at high speed, thereby achieving rapid electrical connection and greatly reducing the generation of electric arcs.

[0032] Please refer to Figures 2-4 , in some embodiments of the present embodiment, the mounting post 6 is of a hollow structure. The energy storage block 7 can reciprocate along the central axis of the mounting post 6. A buffer spring 8 is provided inside the mounting post 6. One end of the buffer spring 8 located inside the mounting post 6 is connected to the energy storage block 7. A buffer chamfer 9 is provided on the side of the energy storage block 7 close to the static piece 3.

[0033] In the present embodiment, the buffer spring 8 is used to buffer the reset of the moving piece 4, which can protect the moving piece 4 and improve the stability of the reset of the moving piece 4. The buffer chamfer 9 is used for the moving piece 4 to hit the chamfer slope when the moving piece 4 resets upward. The vertically upward thrust force is decomposed into a component force in the direction of the axis where the buffer spring 8 is installed, thereby driving the buffer spring 8 to compress, facilitating the buffering of the reset of the moving piece 4 and ensuring the reset of the energy storage block 7.

[0034] Please refer to Figure 4 , in some embodiments of the present embodiment, an arc chamfer 10 is provided on the side of the energy storage block 7 away from the static piece 3.

[0035] In the present embodiment, the arc chamfer 10 is used to remove the sharp edges and burrs on the workpiece, avoiding scratching the user or other objects. The arc chamfer 10 can disperse the stress concentration and reduce the risk of cracking of the part when stressed, thereby improving the durability of the moving piece 4.

[0036] Please refer to Figure 3 , in some embodiments of the present embodiment, a guide groove 11 for guiding the sliding of the moving piece 4 is provided inside the rear seat 1, and a guide block 12 adapted to the guide groove 11 is provided on the moving piece 4.

[0037] In the present embodiment, the guide block 12 and the guide groove 11 cooperate with each other, which can ensure that the moving piece 4 always moves in the vertical direction, thereby avoiding the concentration of spring stress and greatly improving the stability of the operation of its contact system.

[0038] Please refer to Figures 1-4, in some embodiments of the present embodiment, the movable piece 4 is made of an elastic material.

[0039] In the present embodiment, the movable piece 4 is made of a material with elasticity, which can improve the service life of the movable piece 4.

[0040] During use, the insertion piece of the plug is inserted through the panel 2, and the insertion piece abuts against the movable piece 4. The user continuously inserts the plug, and the movable piece 4 abuts against the upper surface of the energy storage block 7. The movable piece 4 continuously bends, and the movement path of the movable piece 4 continuously shrinks until the movable piece 4 crosses the energy storage block 7. The elastic potential energy stored by the continuous bending of the movable piece 4 is released, and the movable piece 4 quickly impacts the static piece 3 to achieve electrical connection. When the plug is pulled out, the return spring 5 extends, the movable piece 4 is separated from the static piece 3, and the movable piece 4 abuts against the chamfered slope on the lower surface of the energy storage block 7. Under the action of the return spring 5 and the buffer spring 8, the movable piece 4 can cross the energy storage block 7 and reset.

[0041] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications 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.
