[0033] For a clearer and more accurate understanding of the content of the present utility model, it will be described in detail below in conjunction with the accompanying drawings. The drawings in the specification show examples of the embodiments of the present utility model, in which the same reference numerals represent the same components. It can be understood that the scale shown in the drawings of the specification is not the actual implementation scale of the present utility model, and it is only for illustrative purposes and not drawn according to the original size.

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 Figure 1 is a schematic diagram of the first structure of the power supply device provided for the embodiment of the utility model, Figure 2 Figure 2 is a schematic diagram of the second structure of the power supply device provided for the embodiment of the utility model. The present application provides a power supply device 100. Among them, the power supply device 100 is provided with a plurality of power lines (not shown in the figure). Each power line supplies the power supply device 100 to be electrically connected to an external terminal. The power supply device 100 includes a box body 1, a receiving groove 2 and a power line bundler 3. The specific features of each component in the power supply device 100 will be described in detail below.

[0035] As Figure 1 and Figure 2 shown, the box body 1 includes a first end face 11, a second end face 12 and a connecting face 13. Among them, the connecting face 13 is respectively connected to the first end face 11 and the second end face 12. The first end face 11 is provided with a plurality of socket holes 111. The second end face 12 is provided with a plurality of card slots 121. Each socket hole 111 is for inserting a corresponding power line. In the present application, both the first end face 11 and the second end face are located on the outer end face of the box body 1. Optionally, the first end face 11 and the second end face 12 are located on the same end face of the outer end face of the box body 1.

[0036] In this embodiment, the receiving groove 2 is located on the second end face 12. The receiving groove 2 includes a plurality of sub-receiving grooves 21. Among them, each sub-receiving groove 21 is used to receive a corresponding power line. Specifically, the inner diameter of each sub-receiving groove 21 is determined according to the outer diameter of the corresponding power line. The cross-sectional shape of the sub-receiving groove 21 is adapted to the cross-sectional shape of the power line. The cross-sectional shape of the sub-receiving groove 21 includes, but is not limited to, shapes such as wavy, annular, elliptical, triangular, etc.

[0037] Further, a plurality of sub-receiving grooves 21 are arranged in a row on the second end face 12. The receiving groove 2 also abuts against the connection between the second end face 12 and the connection face 13. The connection face 13 forms a first included angle and a second included angle with the first end face 11 and the second end face 12 respectively. The connection part is located outside the buckling path where the buckling part 31 buckles into the receiving groove 2. Optionally, the first included angle and the second included angle are equal. The power supply lines corresponding to different external terminals have different outer diameters. The sub-receiving grooves 21 corresponding to power supply lines with different outer diameters have different inner diameters.

[0038] Exemplarily, the number of a plurality of sub-receiving grooves 21 can be 8, that is, the power supply device 100 can accommodate 8 power supply lines side by side. Correspondingly, the cross-sectional shape of the sub-receiving groove 21 is designed as a wavy groove to adapt to the cross-sectional shape of the power supply line, and adapts to the inner diameter size of each power supply line, so that the power supply line is restricted in the corresponding sub-receiving groove 21, and further the power supply line will not slide out of position. Since the sub-receiving grooves 21 corresponding to power supply lines with different outer diameters have different inner diameters, therefore, according to the power supply line and / or the corresponding sub-receiving groove 21, it can be identified which external terminal the power supply line corresponds to.

[0039] Please refer to Figure 4 , which is a schematic diagram of the power supply line bundler provided by the utility model embodiment.

[0040] As Figure 4 shown, the power supply line bundler 3 includes a buckling part 31 and a plurality of buckles 32. Among them, the buckling part 31 has a cavity 33. A plurality of buckles 32 are located in the cavity 33 and protrude from the buckling part 31. Each buckle 32 is made of an elastic material, and each buckle 32 has an asymmetric structure. In this application, each buckle 32 corresponds to a card slot 121. The power supply line bundler 3 enables the buckling part 31 to buckle into the receiving groove through the cooperation of a plurality of buckles 32 and the corresponding card slots 121, and further limits the corresponding power supply line in the corresponding sub-receiving groove 21.

[0041] In this embodiment, the power supply device 100 is printed with an installation mark (not shown in the figure) to indicate the installation direction of the power supply line bundler 3 on the second end face 12 through the installation mark. The installation mark is located on the box body 1 and / or the power supply line bundler 3. When the current installation direction of the power supply line bundler 3 installed on the second end face 12 is different from the installation direction, the buckle 32 cannot cooperate with any card slot 121.

[0042] Exemplarily, when the power supply line bundler 3 is installed on the second end face 12 according to the installation direction indicated by the installation mark, since each buckle 32 has an asymmetric structure, the power supply line bundler 3 can be successfully installed on the second end face 12 only when installed in the corresponding installation direction. When the user ignores the installation direction and installs the power supply line bundler 3 so that the current installation direction is different from the installation direction, the buckle 32 cannot correspond to any card slot 121 and be inserted into the card slot 121, thereby avoiding the wrong installation of the power supply line bundler 3.

[0043] Please refer to Figure 3 , which is a schematic diagram of the card slot provided by the utility model embodiment.

[0044] As Figure 3 shown, each card slot 121 includes a bottom 1211 and a side wall 1212 surrounding the bottom 1211. There is a gap 1213 between the bottom 1211 and the side wall 1212. Along the axis direction perpendicular to the installation direction, each buckle 32 is limited in the corresponding card slot 121 through the gap 1213.

[0045] In this embodiment, the power supply device 100 is also printed with a threading mark (not shown in the figure) to indicate the threading direction of the corresponding power cord through the threading mark through the corresponding sub-accommodating groove 21. When the buckle 32 is deformed by an external force, along the threading direction of the power cord, each buckle 32 is limited in the corresponding card slot 121 through the gap 1213.

[0046] Exemplarily, after sorting and placing a plurality of power cords into the corresponding sub-accommodating grooves 21 and correctly installing the power cord bundler 3 in the installation direction on the second end face 12, apply an external force along the threading direction of the power cord to push the power cord bundler 3, so that the buckle 32 deforms and enters the gap 1213 in the corresponding card slot 121, and makes the buckle 32 rebound and reset to realize the fastening of the power cord bundler 3, thereby realizing the bundling of the power cords.

[0047] Similarly, when it is necessary to loosen the bundled power cords, apply an external force along the direction opposite to the threading direction of the power cord to push the power cord bundler 3, so that the buckle 32 deforms and disengages from the gap 1213 of the corresponding card slot 121, and pull out the power cord bundler 3 along the direction opposite to the installation direction, thereby realizing the release of the power cords.

[0048] In the above embodiment, by respectively providing a socket corresponding to a plurality of power cords and a receiving groove with a plurality of sub-accommodating grooves on the power supply device box body, and combining the power cord bundler to bundle each power cord, the neatness of the layout of a plurality of power cords in the power supply device is improved.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.

[0050] The above are only the preferred embodiments of the present utility model listed, and of course, the scope of the rights of the present utility model cannot be limited thereby. Therefore, the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
