As shown in Figures 1 to 10, this embodiment of the waterproof electric power access device including a power supply track 100 and a current collector head 200 set on said power supply track 100. The invention is mostly used for shelves. In most cases the power supply track 100 is a long flat strip. For the sake of simplicity, said power supply track has a length direction X, a thickness direction Z and a width direction Y. X, Y and Z form a Cartesian coordinate system.

The said power supply track 100 includes: a track body 101, a mounting slot 102, two slots 103, two strip-shaped conductive members 104 and two strips seals 105. Generally, both ends are also provided with end caps 106 and inputs 107, which is state of the art and will not be repeated. The mounting slot 102 is set on the upper surface of the track body 101 and extends in the length direction X, roughly U-shaped, including a bottom 1021 and two opposite sides 1022. The depth of the mounting slot 102 determines the thickness of the track body 101, so generally, it is not too deep. Two slots 103 are set on the two sides 1022, extending in the length direction X. Two strip-shaped conductive members 104 are provided in said slots 103 on each side. Two strip seals 105 seal said slots 103 on each side. The slots 103 in the above have depth in the width direction and the openings/notches of the two slots 103 are opposite to each other. Said strip-shaped conductive members 104 have length and the shape of the cross-section can be circular, triangular, quadrilateral or other, as long as they can be installed into the slots 103. In this embodiment. Said strip-shaped conductive members 104 have a circular cross-section. The position of the slots 103 on the two sides 1022 can be at the bottom, middle or top. In order to keep the thickness of the track body 101 as small as possible, the slots 103 in this embodiment are at the bottom of the two sides 1022. Said strip seals 105 are elastic and therefore has a more variable cross-sectional shape, as long as they can be deformed and then seal the slot 103.

Said current collector head 200 includes a rotation seat 202, an external connector 204 and two current collector members 205. The external connector 204 is provided on said rotation seat 202. The two current collector members 205 are electrically connected to said external connector 204, set on said rotation seat 202 and extending opposite to each other in a direction perpendicular to said thickness direction Z. Said rotation seat 202 rotates so that the two current collector members 205 squeeze through the strip seals 105 on each side and will be inserted into said slots 103 against the corresponding strip-shaped conductive members 104 to achieve electrical connection. Manually rotating the rotation seat 202, the current collector members 205 squeeze through the strip seals 105 and will be inserted into the slots 103. The current collector members 205 can pass above or below the strip seals 105, in this embodiment, below the strip seals 105. Said current collector head 200 is not in connection to the power supply track 100, as shown in Figures 5 and 7.
