Specific embodiments

[0022] The following specific embodiments of the present invention are described in further detail based on the accompanying drawings. It should be understood that the description of embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0023] 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.

[0024] 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.

[0025] 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.

Two current collector members 205 can be in the same plane, or in different planes. In this embodiment, said current collector members 205 are sheets, two current collector members 205 are in the same plane and set in the bottom of the rotation seat 202 on both sides, in the same line.

[0028] Said rotation seat 202 is made of waterproof material, said external connector 204 and the two current collector members 205 are electrically connected inside said rotation seat 202. This not only makes the whole waterproof, but also smaller.

[0029] To make the whole waterproof, in another embodiment, said current collector head 200 further includes a fixed seat 201 and an annular seal 207. Said rotation seat 202 rotates around a rotation center axis 2021 set on said fixed seat 201. Said rotation center axis 2021 is provided parallel to said thickness direction Z, and the annular seal 207 is set on said fixed seat 201 and set around said current collector members 205. The fixed seat 201 can be manually fixed on the power supply track 100 while the current collector members 205 are located in the mounting slot 102, and then rotating the rotation seat 202 makes the current collector members 205 inserted into the slots 103 and electrically connected to the strip-shaped conductive members 104 , while the current collector head 200 is fixed on the power supply track 100 due to the frictional force. The outer side of the annular seal 207 is pressed against the track body 101 to form a sealing structure at the said current collector members 205. The annular seal 207 is fixed to the fixed seat 201 by inserting a hole into a pillar, which is relatively common and will not be repeated here.

[0030] Further, said annular seal 207 comprises a first sealing section 2071 and a second sealing section 2072 affixed to the outer surface of said track body 101.
