The invention discloses a power conversion device with a replaceable plug, comprising a replaceable plug and a power converter body; a containing groove is arranged on the power converter body; an elastic cylindrical thin shell is arranged in the containing groove, and at least one cutting joint is arranged in the radial direction of the thin shell; the plug comprises a base; one end surface of the base is provided with at least two conductive terminals, and the other end surface of the base is provided with a groove which corresponds to the thin shell; the upper end of the groove is closed, and the lower end of the groove is communicated with the outside environment; cam-shaped elastic arms are respectively arranged on the left side and the right side of the groove; the groove is fixedly clamped and connected with the thin shell; and the elastic arms are used for fixing the thin shell in the groove. According to the invention, through the elastic performance of a plastic material and the design of the elastic arms, the replaceable plug can be replaced without being pressed, so that a press structure and other designs which are commonly used in the prior art are reduced, the size of the power conversion device is reduced, the structure is simple, the manufacturing is convenient, and the operation is convenient.
Description
technical field [0001] The invention relates to a power conversion device, in particular to a power conversion device with a replaceable plug. Background technique [0002] With the development of science and technology and the wide application of electrical equipment, a power supply is essential to provide power, but in daily life, the power supply still needs to be connected through various power plugs and sockets. As we all know, the socket is always fixed on a certain object, and the current commonly used sockets have different specifications in different countries. To be able to use it, it is necessary to replace different plugs for the power converter, so that various plugs can share the same converter, which saves space and is convenient to carry. At present, there are several types of power converters with replaceable plugs on the market, but most power converters use a hook pressing mechanism, accommodating space mechanism, rotating spring mechanism, etc., resultin...
