Rotatable and selectable push type multinational power source adapter

Abstract

The invention discloses a rotatable and selectable push type multinational power source adapter, which comprises a shell, a socket and pins with at least two of standards, wherein the socket and the pins are arranged in the shell; the shell comprises an upper cover and base; the base is rotatablely assembled on the upper cover relative to a center rotation shaft; the socket is arranged in the upper cover; the pins with different standards are arranged in the base and synchronously rotates therewith; the pins with different standards are peripherally distributed around the center rotation shaft; each pin can be arranged relative to the center rotation shaft by means of parallel sliding, so that each pin has a work position which is extended out of the shell in a sliding way and a hidden position which is retracted into the shell in a sliding way; the side wall of the upper cover is provided with a positioning slidable groove which is extended parallel with the extension direction of the pins; a sliding component which can freely slide along the positioning slidable groove is arranged correspondingly to the positioning slidable groove; and the sliding component pushes one pin to be extended at a work position which is out of the shell when the pin is rotated into a function region thereof.

Description

technical field [0001] The invention relates to the technology in the field of power plugs suitable for connecting electrical appliances to power sources, in particular to a rotary selection push-out multi-country power adapter. Background technique [0002] The multi-country power adapter is an electrical product that integrates the functions of multi-national standard plugs and sockets. It is mainly used by people who often go abroad for business or travel. The multi-country power adapter can provide people with It is convenient for power transfer of electrical products (such as notebook computers, mobile phones, MP3, MP4, video cameras, etc.) that are always carried with you. [0003] At present, there are some multi-country power adapters on the market, most of which are composed of adapters from different countries. There will be a protruding and exposed situation, and there is a risk of electric shock or short circuit; therefore, in order to solve this problem, many p...

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 in a movable structure, it will be stuck and malfunction due to looseness and shaking during operation. This patent also discloses the combined use of insurance Body and other structures to achieve this function, but simply using these structures to achieve the restrictive effect will cause smooth plug displacement in the convenience of operation, so it is necessary to combine the structure of an operation button to ensure smooth plug displacement during operation, such a structure It is very complicated. It is necessary to press the operation button with one hand and pull the required plug with the other hand to make the plug stretch out. Therefore, it is cumbersome to operate, and malfunctions will also occur under long-term use; research, this application is hereby
