Description

Technical Field

[0001] The present invention relates to a power adapter, and more particularly to a dust-proof and waterproof power adapter.

Background Art

[0002] As global warming becomes increasingly serious, governments around the world are successively encouraging electric vehicles and promoting their popularization. Governments of various countries have installed charging stations beside roads or at rest areas on highways so that electric vehicles can be charged.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims. Also, not all combinations of features described in the embodiments are essential for the solution means of the invention.

[0017] First, an example of a specific embodiment of the power conversion adapter of the present invention will be described with reference to FIGS. 1 to 3.

[0018] FIG. 1 is an external perspective view showing a power conversion adapter according to an embodiment of the present invention. FIG. 2 is a schematic exploded view showing the power conversion adapter shown in FIG. 1. FIG. 3 is another schematic exploded view showing the power conversion adapter shown in FIG. 1. As shown in FIGS. 1 to 3, the power conversion adapter 100 according to the present invention includes a female conversion adapter 110 and a male conversion adapter 120.

[0019] The female conversion adapter 110 has a first housing 111, a rotary ring 112 mounted on the first housing 111, and a plurality of first power terminals 113 and a plurality of first signal terminals 114 fixed to the first housing 111. These first power terminals 113 and these first signal terminals 114 are used to connect to an AC power supply via a first cable 11. The inner surface of the rotary ring 112 has n bumps 112a that surround the rotary ring 112 at equal angles in the axial direction of the rotary ring 112. n is an integer greater than 1, and preferably 3.

[0020] The male conversion adapter 120 has a second housing 121, and a plurality of second power terminals 122 and a plurality of second signal terminals 123 fixed to the second housing 121. These second power terminals 122 and these second signal terminals 123 are used to connect to a control module via a second cable 12. The control module is a charging gun, and the outer surface of the second housing 121 has n groove structures 124 that surround it isogonally in the axial direction of the second housing 121. Each groove structure 124 has an inclined guide groove 124a and an engagement slot 124b communicating with the inclined guide groove 124a.

[0021] When docking the female conversion adapter 110 and the male conversion adapter 120, first, perform an axial docking operation so that these bumps 112a slide correspondingly into these inclined guide grooves 124a, bringing these first power terminals 113 and these first signal terminals 114, and these second power terminals 122 and these second signal terminals 123 closer to each other and completing the corresponding connection (see Fig. 4).

[0022] Next, perform a rotation operation so that these bumps 112a slide correspondingly into these engagement slots 124b to tightly engage the female conversion adapter 110 and the male conversion adapter 120 with each other (see Fig. 5).

[0023] Also, when tightly engaging the female conversion adapter 110 and the male conversion adapter 120 with each other, in order to further provide a waterproof effect, the first housing 111 is covered with a waterproof gasket 115.
