Description

Waterproof power adapter with replaceable plug

Technical Field

The utility model relates to the technical field of power adapters, in particular to a waterproof power adapter with a replaceable plug.

Background

With the daily and new variation of vehicles, people can simply and quickly go to and from countries of the world, but because the voltages adopted by the countries of the world are different, the applicability of the electrical equipment carried by passengers is greatly limited, so that a power adapter with changeable voltage is developed, passengers going to and from the countries can pass through the adapter, and the voltage provided by the country where the passengers arrive is regulated into the voltage applicable to the electrical equipment carried by the passengers in a step-up or step-down mode.

Although the power adapter can effectively solve the problem that whether the voltage can be applied to the electrical equipment or not, the power jack is specially designed into different forms based on safety and other factors in each country so as to distinguish the supplied voltage, and the plug of the electrical equipment which is not applicable to the voltage is prevented from being inserted by a user.

In order to effectively solve the problem, a plug of the power adapter is designed as a replaceable movable plug to be matched with various power jacks in different forms. The power supply with replaceable power plug disclosed in CN1658443C comprises a power supply body, a movable plug and a clamping positioning piece, wherein a groove part with a conductive piece group at the bottom is arranged on the side edge of the power supply body, a plurality of grooves are arranged on the wall surface of the groove part, and an embedded space communicated with the groove part is respectively arranged on the same side wall surface of the groove; the movable plug is provided with a ring-shaped body fixed on the opposite side of the pin side and a conductive contact connected with the pin, the outer side wall surface of the ring-shaped body is provided with a plurality of positioning blocks, and one end edge of the ring-shaped body is provided with a positioning groove; the clamping and positioning piece is arranged at one side of the groove part, one end of the clamping and positioning piece, which faces the bottom of the groove part, is provided with a bump for being mutually clamped with the positioning groove, and the other end of the clamping and positioning piece extends out of the groove part and is a free end.

When the power supply device with the structure is connected with the power supply device body, the movable plug is rotated to enable the positioning blocks to be respectively embedded in the embedded spaces of the grooves after the positioning blocks on the movable plug are respectively matched with the grooves on the wall surfaces of the groove parts, and the positioning grooves are embedded through the convex blocks of the clamping positioning pieces, so that the plug is limited to be embedded and fixed on the power supply device body, namely: the movable plug can not move along the axial direction of the power supply body by combining the positioning block and the embedded space, and can not rotate along the circumferential direction of the power supply body by combining the clamping positioning piece and the positioning groove.

For the power supply with the structure, because the clamping locating piece is elastically deformed when being pressed, a gap is necessarily formed between the clamping locating piece and the power supply body, and therefore, if liquid enters the groove part through the gap, the liquid is applied to the two groups of conductive contacts and the conductive piece group, and the circuit inside the power supply body is necessarily short-circuited.
