Description

Technical Field

[0001] The utility model relates to the technical field of power plugs, and more specifically to a safe and stable plug. 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] For example, a Chinese patent application numbered CN212366270U discloses a plug with rotatable pins, which is provided with a rotating shaft so that the conductive pins can be rotated through the rotating shaft, and the conductive pins can be stored in a first slot. The plug has high safety, stability and reliability. Even if the product is carried together with other items, the conductive pins will not cause damage to or even puncture other items.

[0005] However, the above-mentioned conductive spring is not firmly installed and is easy to shake during use. Moreover, as the use time increases, the elasticity of the conductive spring decreases, which causes the contact between the conductive spring and the conductive pin to become unstable, thereby seriously affecting the current transmission efficiency. Utility Model Content

[0030] 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.

[0031] 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.

[0032] It should be noted that the conductive spring is not installed firmly and is easy to shake during use. As the use time increases, the elasticity of the conductive spring decreases, which causes the contact between the conductive spring and the conductive pin to become unstable, thus seriously affecting the current transmission efficiency.

[0033] like Figure 1-Figure 4 As shown, this embodiment provides a safe and stable plug 1, in which the conductive spring clip 30 is hung on the mounting bracket 40 and can be firmly mounted on the mounting bracket 40 without shaking during use, and the first inclined surface 312 of the conductive spring clip 30 is always in contact with the shell of the plug 1, so that the conductive spring clip 30 can maintain stable contact with the conductive pin 10, so that even if some vibration or shaking occurs during the plugging and unplugging process, the conductive spring clip 30 can maintain contact with the shell, thereby ensuring a stable connection with the conductive pin 10.

[0034] Specifically, a safe and stable plug 1 includes a conductive pin 10, a conductive spring 30 and a mounting support 40. The two conductive pins 10 are connected by a mounting portion 20 and are rotatably mounted on the mounting support 40 through the mounting portion 20. The conductive spring 30 includes an elastic contact portion 31 and a hanging portion 32. The elastic contact portion 31 is folded at a first folding portion 311 to form a first inclined surface 312 that is elastically supported by the outer shell of the plug 1, so that the elastic contact portion 31 is stably connected to the conductive pin 10. The hanging portion 32 is folded at a second folding portion 321 to form a second inclined surface 322 that is hung on the mounting support 40, so that the conductive spring 30 is stably mounted on the mounting support 40.

[0035] The safe and stable plug 1 adopts a design in which two conductive pins 10 are connected through a mounting portion 20 and are rotatably mounted on a mounting support 40 through the mounting portion 20. The conductive pins 10 can be folded and stored in the plug 1 for easy carrying.

[0036] The conductive spring sheet 30 includes an elastic contact portion 31 and a hanging portion 32, so that the conductive spring sheet 30 can maintain stable contact with the conductive pin 10 and can be firmly mounted on the mounting support 40. The first inclined surface 312 formed by the folded elastic contact portion 31 forms an elastic support with the outer shell of the plug 1, so that even if some vibration or shaking occurs during the plugging and unplugging process, the conductive spring sheet 30 can maintain a close fit with the outer shell, thereby ensuring a stable connection with the conductive pin 10.

[0037] The second inclined surface 322 formed by the folded hanging portion 32 is hung on the mounting support 40, so that the conductive spring piece 30 can be firmly fixed on the mounting support 40 and will not be displaced or fall off due to external force or vibration. This not only ensures the stability of the installation of the conductive spring piece 30, but also greatly improves the safety of the entire plug 1.

[0038] In one embodiment, an arc-shaped groove 41 is provided on the mounting support 40, and a mounting space for the mounting portion 20 is formed between the arc-shaped groove 41 and the outer shell of the plug 1. The bottom of the mounting portion 20 is arc-shaped, and the arc-shaped bottom of the mounting portion 20 cooperates with the arc-shaped groove 41 to reduce the friction during the rotation of the mounting portion 20.

[0039] In one embodiment, a first slot 50 for the conductive pin 10 to rotate is provided on the outer shell of the plug 1. When the plug 1 is in use, the conductive pin 10 is perpendicular to the outer shell of the plug 1. When the plug 1 is not in use, the conductive pin 10 can be rotated 90 degrees and placed in the first slot 50. The conductive pin 10 can be folded and stored in the first slot 50 of the plug 1, which is convenient to carry and avoids accidental damage that may be caused by the conductive pin 10 when not in use.

[0040] The mounting portion 20 is provided with two limiting grooves 21 , and the mounting support 40 is provided with an elastic limiting portion 42 . The elastic limiting portion 42 switches between the two limiting grooves 21 , thereby controlling the conductive pin 10 to switch between the use state and the non-use state.

[0041] A stopper 22 is provided in the middle of the two limit slots 21, and the stopper 22 blocks the elastic limiter 42 from switching between the two limit slots 21, so that the conductive pin 10 remains stable when in use or not in use. The purpose of providing the stopper 22 is to block the elastic limiter 42 from switching between the two limit slots 21 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.

[0042] The mounting bracket 40 is provided with a through slot 43, and one side of the through slot 43 extends inward to form an elastic limiting portion 42. Specifically, when the elastic limiting portion 42 switches between the two limiting slots 21, it will be blocked by the blocking portion 22. After the conductive pin 10 is rotated with a little force, the elastic limiting portion 42 will move downward, and after being separated from the blocking portion 22, it will move from one limiting slot 21 to the other limiting slot 21, thereby realizing the switching of the conductive pin 10 between the use state and the non-use state.

[0043] In one embodiment, the mounting bracket 40 is provided with a hanging hole 44, and the mounting bracket 40 is provided with a hanging platform 45 on one side of the hanging hole 44, so that the second inclined surface 322 passes through the hanging hole 44 and is hung on the hanging platform 45, thereby realizing stable installation of the conductive spring 30. The setting of the hanging hole 44 allows the hanging portion 32 of the conductive spring 30 to pass smoothly, and the hanging platform 45 provides a solid support point, so that the second inclined surface 322 can be stably hung thereon.

[0044] The conductive pin 10 has a first extension portion 11 that passes through the mounting portion 20 and can be elastically contacted and connected with the conductive spring sheet 30. The first extension portion 11 can be elastically contacted and connected with the conductive spring sheet 30.

[0045] The conductive spring piece 30 is an integrally formed structure, which enhances the overall strength of the conductive spring piece 30 and improves its durability and reliability.

[0046] In one embodiment, the conductive spring clip 30 also includes a fixing portion 33 that is inserted and fixed to the circuit board. The fixing portion 33 is folded twice to form a hook shape. The hook-shaped design allows the conductive spring clip 30 to be more firmly fixed when inserted into the corresponding slot or contact point of the circuit board, which not only reduces the risk of falling off due to vibration or external forces, but also enhances the stability of the overall connection. The hook-shaped structure can also increase the contact area between the conductive spring clip 30 and the contact point. This means that there are more paths for current to pass through, thereby reducing resistance and improving conductivity efficiency.

[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.
