BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to electrical devices, and in particular, it relates to a power receptacle.

Description of Related Art

In conventional power receptacles, because of the large variety of different products, the manufacturing of different products require different molds and production equipment. This results in high production cost and complex warehouse management. It also requires skilled workers, making it difficult to change from one model to another.

SUMMARY

To solve the above problems, the present invention provides a power receptacle, which includes an upper cover, a middle cover, and a base assembly. The middle cover includes an interface group, the interface group including at least one first-type interface, and at least one second-type interface and/or at least one third-type interface. The upper cover includes a matching interface group, the matching interface group including matching interfaces that match at least some of the corresponding interfaces of the interface group. The upper cover and the middle cover are removably attached to each other.

In some embodiments, a number of matching interfaces in the matching interface group on the upper cover is equal to or smaller than a number of interfaces in the interface group on the middle cover.

In some embodiments, any one of the at least one first-type interface, the at least one second-type interface and/or the at least one third-type interface is oriented parallel to a short side or a long side of the middle cover.

In some embodiments, the power receptacle further includes an illumination light. The illumination light can replace any one of the first-type interfaces, second-type interfaces, third-type interfaces or the matching interfaces.

In some embodiments, the at least one first-type interface includes at least one AC output interface.

In some embodiments, the at least one second-type interface includes at least one USB (Universal Serial Bus) Type-A or Type-B interface.

In some embodiments, the at least one third-type interface includes at least one USB (Universal Serial Bus) Type-C interface.

In some embodiments, the upper cover and the middle cover are attached to each other by snap connectors.

In some embodiments, the upper cover and the middle cover are slidably engaged with each other.

In some embodiments, the middle cover includes a step feature, and wherein the upper cover is attached to the step feature.

In some embodiments, the upper cover has one of a plurality of colors.

In the power receptacles according to embodiments of the present invention, the base assembly does not need to be changed, and the upper cover can be flexibly changed based on user's need, which enhances the applicability and versatility of the power receptacle and saves cost. Moreover, the upper cover can be replaced without requiring skilled workers, which manes convenient to use.
