TWM258472U - Structure for identifying the compatibility with socket and plugs - Google Patents

Description

M258472 新型 Description of the new type: [Technical field to which the new type belongs] This creation is related to the structural design of a kind of electric_header and socket, so that the same plug and socket can be automatically identified when combined, and prevent mis-plugging Avoid those who cause damage. [Previous technology] Many electric appliances ② are mainly a combination of a plug and a socket for the purpose of connecting to a pen. The structure of Wei Changzhi is shown in the figure—shown by plug ⑴ ^ socket 航, and at the same time, the inside of socket ⑵ is also inserted into the front end hole, and the outside of plug 与 is in contact with the conductive sheet (22), = To the effect of conduction. However, different f devices are different, and f has different w or Dian requirements. Shame can not be independent reading and input in different = insert, on 'otherwise it is likely to cause damage to electricity H, or even cause other disasters. . Since the self-knowledged structures all have similar shapes, it is easy for mis-insertion to occur, and need to be improved. [New content] As shown in Nos. 2 to 4 of the ginseng surface, the office is mainly inside the socket 务, and the service-the convex ring (23), is located on the outer edge of the plug ⑵), and the plug 端 前端 夕 卜 # Yes-concave part (11), when plug ⑴ is inserted into socket ⑵, the inner hole of the plug lock (21) ', and the recessed part (11) is for the convex & ⑽ in the socket ⑽ [Embodiment] ji The official uses Rishou 'because of the socket ⑵β of this creation, a convex ring (23) is located on the outer edge of f pin') If it is mated with a plug with the same outer diameter, the front end will be = convex ring ⑵) The plug (1) designed to cooperate with this creation has a concave portion (11), which can provide an extension space for the convex ring (23), and the plug can be completely inserted into the socket ( In 2), as shown in Figures 5 and 6, M258472 obtained a stable and reliable conductive connection. It is known that this creation can provide a simple way to ‘knowledge structure’ and ensure that no wrong combinations occur. [Schematic description] Figure 1 is a combined sectional view of a conventional plug and socket. Figure 2 is a combined perspective view of the creation. Figure 3 is an exploded perspective view of the creation. Figure 4 is an anatomical view of the creation. Figure 5 is a combined sectional view of the creation. It is a partial enlarged view of Figure V. [Illustration of drawing number] (1) Plug (11) Recess (2) Socket (21) Pin (22) Conductive piece (23) Convex ring

Claims (1)

M258472 范围 、 Scope of patent application: A power plug and socket identification structure (2), including a power plug and socket, wherein the socket is provided with a convex ring located on the outer edge of the pin, and a concave portion is provided on the outer edge of the front end of the plug. When the plug is inserted into the socket, the inner hole of the plug fits the pin, and the recessed portion is for the convex ring in the socket to be clamped.
