Description

Technical Field

[0001] The utility model relates to the technical field of power plugs, and more specifically to a power plug with a metal conductive spring and foldable plug pins. Background Art

[0002] With the rapid development of science and technology and the continuous progress of society, people's living standards are improving day by day. Electronic products such as mobile phones, laptops, tablet computers, Bluetooth headsets, cameras, etc. are becoming more and more popular. These electronic products have become an important part of people's lives and work. In order to meet people's increasing needs, the requirements for power adapters for these electronic products are getting higher and higher. There are more and more high-power, large-volume, and heavy adapters, and when traveling or on business trips, these power adapters will be carried with them. A power adapter usually includes a body and a plug set on the body. The plug is inserted into a power socket and connected to the body and the electronic product through a cable, so that the power adapter supplies power to the corresponding electronic product.

[0003] At present, the plug of a common power adapter includes at least two conductive pins. When in use, the power adapter is connected to the corresponding electronic product, and the conductive pins of the plug are inserted into the corresponding power socket, and the electric energy is conducted into the corresponding electronic product through the adapter. However, the conductive pins of the plug of a traditional power adapter are fixed and extend outside the power adapter, which takes up a large space and is not convenient for product packaging, transportation, storage, carrying, etc. Moreover, when carried together with other items, the metal conductive pins may damage or even puncture other items, resulting in low safety and reliability, which affects the application and development of the product.

[0004] The existing method improves the safety, stability and reliability of the plug by setting the pins as rotatable pins and storing them in the shell of the plug. Even if the product is carried together with other items, the conductive pins will not cause damage or even puncture to other items.

[0005] However, the conductive spring sheet in the existing plug is in a "V" shape, with one side of the "V"-shaped conductive spring sheet plugged into the circuit board and the other side elastically contacting and connecting with the conductive pin. However, as the use time increases, the elasticity of the conductive spring sheet will gradually weaken, and the position of the conductive spring sheet will be lower than the originally preset contact position. The conductive spring sheet may not be able to effectively contact the conductive pin, thereby causing the plug to be unable to be used normally. Utility Model Content

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices. Terms such as "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "bottom", etc. are based on the directions or positions shown in the drawings, which are only for the convenience of description and cannot be understood as limitations on the present technical solution.

[0033] It should be noted that, however, the conductive spring sheet in the existing plug is in a "V" shape, with one side of the "V"-shaped conductive spring sheet being plugged into the circuit board, and the other side being elastically connected to the conductive pin. However, as the use time increases, the elasticity of the conductive spring sheet will gradually weaken, and the position of the conductive spring sheet will be lower than the originally preset contact position. The conductive spring sheet may not be able to effectively contact the conductive pin, thereby causing the plug to fail to be used normally.

[0034] like Figure 1-Figure 4 As shown, the present embodiment provides a metal conductive spring sheet 40, which is folded twice to form a "U" shape and can clamp the contact point of the conductive pin 10, and a weight block 43 is provided at the end of the conductive spring sheet 40. The weight of the weight block 43 drives one side of the "U"-shaped part to press down, so that when the conductive spring sheet 40 clamps the contact point of the conductive pin 10, the contact point of the conductive spring sheet 40 and the conductive pin 10 can always be in elastic contact.

[0035] Specifically, the conductive spring clip 40 is an integrally formed structure, and the conductive spring clip 40 is folded at the first folding portion 41 and the second folding portion 42 to form a "U" shape. A weight block 43 is disposed at one end of the conductive spring clip 40 close to the "U"-shaped portion, so that when the contact point of the conductive pin 10 is placed in the "U"-shaped portion of the conductive spring clip 40, the conductive spring clip 40 is always in elastic contact with the conductive pin 10.

[0036] When the elastic force of the conductive spring sheet 40 is optimal, the conductive spring sheet 40 can contact the contact point of the conductive pin 10. As the use time increases, the elastic force of the conductive spring sheet 40 weakens, but the conductive spring sheet 40 still maintains contact with the contact point of the conductive pin 10. There will be no problem that the conductive spring sheet 40 cannot effectively contact the conductive pin 10, thereby causing the plug to be unable to be used normally.

[0037] This embodiment also provides a power plug with foldable pins, which clamps the first extension 11 of the conductive pin 10 through a "U"-shaped conductive spring 40, and under the self-gravity of the weight block 43 on the conductive spring 40, an additional holding force is provided for the conductive spring 40, ensuring that the conductive spring 40 and the first extension 11 of the conductive pin 10 always maintain close elastic contact. As the use time increases, the conductive spring 40 will not separate from the conductive pin 10 and can always be in contact with the conductive pin 10. Not only improves the durability of the plug, but also extends its service life. During use, users do not need to frequently replace the plug, which greatly saves time and cost.

[0038] Specifically, the power plug body 1 includes a conductive pin 10, a rotating shaft 20, a mounting plate 30 and a conductive spring 40. The two conductive pins 10 are respectively placed at both ends of the rotating shaft 20 and are mounted on the mounting plate 30 through the rotating shaft 20. The two conductive pins 10 respectively have a first extension portion 11 passing through the rotating shaft 20, and the first extension portion 11 is placed in a "U"-shaped portion of the conductive spring 40 to connect the conductive pin 10 and the conductive spring 40.

[0039] In one embodiment, the length of the first extension portion 11 is not less than half the width of the conductive spring sheet 40, ensuring that the conductive pin 10 can be in stable contact with the conductive spring sheet 40. In this way, even if some vibration or shaking occurs during the plugging and unplugging process, the conductive spring sheet 40 can maintain contact with the conductive pin 10, thereby ensuring a stable connection with the conductive pin 10.

[0040] In one embodiment, the other end of the conductive spring 40 is provided with a mounting hole 44, and the mounting plate 30 is provided with a corresponding mounting post 31, and the mounting hole 44 is mounted on the mounting post 31, thereby realizing the stable fixation of the conductive spring 40 on the mounting plate 30. Not only can the stability of the conductive spring 40 be ensured, but also the shaking or displacement that may occur during use can be effectively prevented, thereby ensuring the stability and safety of the power plug.

[0041] In one embodiment, two conductive springs 40 are respectively disposed on both sides of the rotating shaft 20 to clamp the first extension portions 11 of the two conductive pins 10. In order to further enhance the stability of the conductive springs 40, the mounting plate 30 is provided with a mounting platform 32 below the conductive springs 40. The mounting platform 32 supports the conductive springs 40 and effectively prevents the conductive springs 40 from sagging or deformation during use.

[0042] In one embodiment, a receiving slot 50 for receiving the conductive pin 10 is provided on the power plug body 1. When the power plug body 1 is in use, the conductive pin 10 is perpendicular to the shell of the power plug body 1. When the plug is not in use, the conductive pin 10 can be rotated 90 degrees and placed in the receiving slot 50. The conductive pin 10 can be folded and received in the receiving slot 50 of the power plug body 1, which is convenient to carry and avoids accidental damage caused by the conductive pin 10 when not in use.

[0043] The end of the rotating shaft 20 protrudes outward to form a rotating column, the mounting plate 30 is provided with a first rotating groove 33 at a position corresponding to the rotating column, and the housing of the power plug body 1 is provided with a second rotating groove at a position corresponding to the rotating column, and the first rotating groove 33 and the second rotating groove together enclose a rotating space of the rotating column. The rotating column at the end of the rotating shaft 20 rotates in the rotating space enclosed by the first rotating groove 33 and the second rotating groove, driving the conductive pin 10 to switch between the use state and the non-use state.

[0044] The rotating shaft 20 is provided with two limiting grooves 22 , and the mounting plate 30 is provided with a limiting protrusion 34 . The limiting protrusion 34 switches between the two limiting grooves 22 to realize the switching of the conductive pin 10 between the use state and the non-use state.

[0045] A stopper 23 is provided between the two limit grooves 22, and the stopper 23 is used to prevent the limit protrusion 34 from switching between the two limit grooves 22, so that the conductive pin 10 remains stable when in use or not in use. The purpose of providing the stopper 23 is to prevent the limit protrusion 34 from switching between the two limit grooves 22 at will, thereby ensuring that the conductive pin 10 does not shake when in use, i.e., when inserted into a socket for power transmission, and does not accidentally pop out when in non-use, i.e., when stored.

[0046] A first beveled surface 231 is provided on both sides of the stopper 23, and the two first beveled surfaces 231 face the inner side of the stopper 23. A second beveled surface 341 is provided on both sides of the limiting protrusion 34, and the two second beveled surfaces 341 face the inner side of the limiting protrusion 34. The setting of the first beveled surface 231 and the second beveled surface 341 facilitates the limiting protrusion 34 to detach from the stopper 23, so that the limiting protrusion 34 can switch smoothly between the two limiting grooves 22.

[0047] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0048] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
