Multi-country universal electric adaptor

Abstract

An electric plug adaptor of international- universal type consists of top cover, base two sliding slots on external wall, standard plug corresponding to each sliding slot position, rotary switch including a bar sliding block and a braking button. It is featured as setting a ledge and a groove closing to ledge bottom on top of plug to let bar sliding block slide along each ledge through bar sliding slot in order to have only one plug of plug adaptor connected on independently and selectively.

Description

technical field [0001] The invention relates to a communication adapter that can be used in different power socket standards used in different countries, in particular to a hidden multi-country power adapter that allows only a single group of plugs to protrude and plug in and conduct electricity through the adapter socket. connector. Background technique [0002] With the continuous development of social economy, people travel abroad, business trips and other matters more and more frequently, so before going abroad, they need to carry some corresponding communication equipment or electrical appliances to facilitate travel, such as laptops, mobile phones, MP3 and other electronic products, these Electronic products are all power-consuming products, so it is necessary to prepare matching adapters for power shortages; at present, because communication interfaces in countries around the world adopt different standards, such as American, British, Australian, and European Therefo...

Problems solved by technology

[0004] For example, Taiwan patent TW541768 discloses a multi-country adapter socket, which is equipped with a safety device and a corresponding safety shield through the position corresponding to the action of the power pin on the inner side, so that the control rod and the positioning block can be pushed to the left. , The state of right displacement is to forcefully restrict the positioning of the power pins of each line, but it can only make a single set of power pins unrestricted and can be extended and inserted, so that the adapter socket can have a mandatory protective effect, thereby In order to improve the safety during use; however, for the current design concept of light, thin, short and small, it is necessary to add such safety devices and corresponding safety shutters inside, and its space is limited, which is not conducive to assembly; especially its structure Complicated, often stuck or malfunctioning when operating the buttons, which brings limitations to the use

[0005] Referring again to a power plug disclosed in Chinese patent CN1539187A, it has a housing and at least two different standardized plug contacts movably supported in the housing, and the plug contacts respectively have two conductive contact pins, and these contact pins can Moving out of the housing along the sliding path into an active position and into an inactive position in the housing, it is essential that there is also at least one braking body, which is movable relative to the housing and the plug connection and passes through a plug contact fixed in a position outside the ineffective position, in which the braking body is arranged on the sliding travel of the remaining plug contacts and thus prevents the other plug contact from moving from the inactive position into the active position; the technical solution is The brake body installed between the sliding strokes is used to limit the displacement of the remaining plug contacts. Since the brake body is a movable structure, it will be stuck and malfunction due to looseness and shaking during operation. This patent also discloses the combination of using The safety body and other structures are used to realize this function, but simply using these structures to achieve the restrictive effect will cause the phenomenon of plug displacement not being smooth during operation, so it is necessary to combine the structure of an operation button to work together to ensure smooth plug displacement during operation. Such a structure is very complicated. When operating, one hand must hold down the operation button, and at the same time pull the required plug with the other hand to make the plug protrude. Therefore, it is troublesome to operate, and malfunctions will occur under long-term use; the applicant considers this technology For further research on the scheme, this application is hereby proposed
