Description

Technical Field

[0001] This application relates to the field of electrical connections, and more particularly to a PDU power supply. Background Technology

[0002] The description in this section provides only background information relevant to the disclosure of this application and does not constitute prior art.

[0003] PDU stands for "Power Distribution Unit," also known as a rack-mounted power distribution socket. It is a product designed to provide power distribution for rack-mounted electrical equipment, offering suitable rack-mounted power distribution solutions for different power environments.

[0004] To ensure that PDU power supplies are installed in a fixed orientation, the external ports of a typical PDU power supply are located at one end of its longer side. Considering that cabinet cabling or space limitations may cause the text or icons output by the display module to be upside down, this may prevent maintenance personnel from intuitively reading information such as voltage and current.

[0005] In addition, existing technologies often employ either a rotatable independent display head or a software-level image flipping solution to achieve bidirectional installation. The former increases the number of parts and costs, while the latter relies on control chip support and has insufficient reliability.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0007] Based on the aforementioned deficiencies in the prior art, the PDU power supply in this application, through a simple, reliable, and low-cost mechanical structure, ensures that the content output by the display unit is always visible in a positive direction.

[0008] To achieve the above objectives, this application provides the following technical solution: a PDU power supply, comprising: The housing of a long strip profile has a mounting groove on its front side along its length, and the two ends of the mounting groove respectively form a first limiting part and a second limiting part that are mirror-symmetrical. The display module includes a panel inserted into the mounting slot and a display portion formed on the panel. The panel has a first joint portion and a second joint portion at both ends in its length direction. The first joint can be detachably connected to the first limiting part and the second limiting part respectively; and the second joint can be detachably connected to both the first limiting part and the second limiting part respectively, so that the display part can keep the visible surface facing outward in both the first assembly posture and the second assembly posture rotated 180° relative to the first assembly posture.

[0009] The first limiting part and the second limiting part are mirror-symmetric structures, while the first joining part and the second joining part are not mirror-symmetric structures.

[0010] Preferably, the first joining portion can be fixedly connected to the first limiting portion or the second limiting portion, and the second joining portion can be fitted and engaged with the first limiting portion or the second limiting portion.

[0011] Preferably, both the first limiting portion and the second limiting portion include a first opening, and the first engaging portion includes a second opening that can respectively engage with the two first openings.

[0012] Preferably, both the first limiting portion and the second limiting portion include a baffle extending from the sidewall of the mounting groove and an insertion slot formed between the baffle and the sidewall. The second joint portion of the panel includes a first folded edge that folds inward and a second folded edge that extends away from the panel from the first folded edge. The second folded edge can be inserted into the insertion slot.

[0013] Preferably, the first limiting portion and the second limiting portion each include a first opening, and the first engaging portion includes a second opening that can respectively engage with the two first openings, the first openings being formed on the baffle wall.

[0014] Preferably, in the first assembly posture, the first joining portion is fixedly connected to the first limiting portion, and the second joining portion is fitted with the second limiting portion; in the second assembly posture, the first joining portion is fixedly connected to the second limiting portion, and the second joining portion is fitted with the first limiting portion.

[0015] Preferably, the display unit is electrically connected to a control board located inside the housing via a sufficiently long flexible connecting line to accommodate a first assembly posture and a second assembly posture.

[0016] With the above technical solution, the beneficial effect of this application is that the display unit can output content in a positive orientation regardless of whether the PDU power supply is installed in a forward orientation or inverted orientation (180° opposite to the forward orientation).

[0033] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0034] It should be noted that in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.

[0035] Reference Figure 1 and Figure 2 As shown in the figure, this application discloses a PDU power supply, including: The housing 1 of the elongated profile has a mounting groove 11 on its front side along its length direction, and a first limiting part 12 and a second limiting part 13 are formed at both ends of the mounting groove 11. The display module includes a panel 2 and a display portion 3 formed on the panel 2. The panel 2 has a first joint portion 21 and a second joint portion 22 at both ends in its length direction. The first joint 21 and the first limiting part 12, and the second joint 22 and the second limiting part 13 are all detachably connected, so that the display part 3 can keep the visible surface facing outward in both the first assembly posture and the second assembly posture rotated 180° relative to the first assembly posture.

[0036] With the above structure, regardless of whether the PDU power supply is installed in a forward or inverted position (180° opposite to the forward position), the display unit 3 can output content in a forward position.

[0037] Specifically, refer to Figure 3 As shown, the housing 1 can be a profile extending along its length. The housing 1 can also be provided with multiple plug interfaces 92, thereby providing power to each plug through each plug interface 92. Combined with... Figure 4 and Figure 5 As shown, a mounting groove 11 extending along the length direction is provided on the front of the housing 1. A first limiting part 12 and a second limiting part 13 are formed at both ends of the mounting groove 11, respectively. The first limiting part 12 and the second limiting part 13 are mirror-symmetrical about the longitudinal center line of the mounting groove 11 along the length direction.

[0038] Reference Figure 6 As shown, the display module includes a panel 2, which can be inserted into the mounting slot 11. In this embodiment, the display unit 3 includes a display screen disposed on the panel 2, thereby outputting text, numbers, patterns, pictures, and other content. In another optional embodiment, the display unit 3 is fixed to the back of the panel 2. The panel 2 has a light-transmitting panel 2 disposed at the display unit 3. Through the display unit 3 and the light-transmitting panel 2, text, numbers, patterns, pictures, and other content can be output.

[0039] Combination Figure 7 and Figure 8 As shown, the panel 2 has a first joint 21 and a second joint 22 at its two ends along its length. The first joint 21 and the second joint 22 are not mirror-symmetric structures.

[0040] Specifically, in the first assembled state, the first engaging portion 21 can be detachably connected to the first limiting portion 12; the second engaging portion 22 can be detachably connected to the second limiting portion 13. In the second assembled state, the second engaging portion 22 can be detachably connected to the first limiting portion 12; the first engaging portion 21 can be detachably connected to the second limiting portion 13.

[0041] In this embodiment, the first connecting portion 21 can be detachably and fixedly connected to the first limiting portion 12 and the second limiting portion 13, respectively. The second connecting portion 22 can be fitted into the first limiting portion 12 and the second limiting portion 13, respectively.

[0042] Specifically, both the first limiting portion 12 and the second limiting portion 13 include a baffle 51 extending from the sidewall of the mounting groove 11 and an insertion slot 52 formed between the baffle 51 and the sidewall. Preferably, the baffle 51 is recessed inward to form a relief portion 511. The insertion slot 52 is formed between the relief portion 511 and the sidewall of the mounting groove 11. The second joining portion 22 of the panel 2 extends inward to form a first folded edge 61, and a second folded edge 62 extends from the first folded edge 61 in a direction away from the panel 2, thereby allowing the second folded edge 62 to be inserted into the insertion slot 52.

[0043] In this embodiment, the housing 1, the first limiting part 12, and the second limiting part 13 can be integrally formed by stamping with a mold. During the molding process, a baffle 51 with a material thickness lower than the front of the housing 1 is first molded out, so that the panel 2 is on the same plane as the housing 1 after installation. After the baffle 51 is molded out, a clearance part 511 is molded out in the middle of the baffle 51 to meet both snap-fit ​​installation and anti-loosening screw travel.

[0044] Preferably, the clearance portion 511 is fixed to the panel 2 by anti-detachment screws. The anti-detachment screws ensure that the panel 2 will not accidentally fall off the housing 1 during disassembly and installation.

[0045] Meanwhile, the distance from the front of the clearance part 511 to the front of the housing 1 should be slightly greater than the distance from the top of the anti-loosening screw clip. In this embodiment, the distance from the top of the anti-loosening screw clip is 4.15mm, and the clearance distance of our designed installation mechanism is 5.3mm, which is greater than 4.15mm. Preferably, the clearance distance of the installation mechanism is greater than the distance from the top of the anti-loosening screw clip but less than 2mm. This ensures the smooth installation of the anti-loosening screw and also meets the requirements of the meter head snap-on installation. At the same time, the anti-loosening screw can also be selected as short as possible to save time and effort during installation.

[0046] The first engaging portion 21 can be fixedly connected to the first limiting portion 12 or the second limiting portion 13 by fasteners such as bolts or screws. Both the first limiting portion 12 and the second limiting portion 13 include a first opening 41, and the first engaging portion 21 includes a second opening 42 that can respectively mate with the two first openings 41. Preferably, the first opening 41 is formed on the baffle wall 51.

[0047] Reference Figure 9 As shown, preferably, the display unit 3 is electrically connected to the control board 7 housed within the housing 1 via a sufficiently long flexible connecting cable 8 to accommodate a first assembly posture and a second assembly posture. A network interface 91 may also be fixedly mounted on the panel 2. Of course, in other optional embodiments, the panel 2 may also be provided with other functional components.

[0048] The installation method of the PDU power supply in this application includes the following steps: When the display unit is in the positive output position, the second joint portion 22 of the panel 2 is located below the first joint portion 21, and the first limiting portion 12 is located above the second limiting portion 13. The second joint portion 22 of the panel 2 is engaged with the second limiting portion 13; After the fitting is completed, the first joint portion 21 of the panel 2 is fixedly connected to the first limiting portion 12 by fasteners.

[0049] In some embodiments, the display unit 3 is located at the top of the panel 2, which makes the display unit 3 relatively simple and prevents other parts from interfering with the output of the display unit.

[0050] In some embodiments, in the installed state, the first joint 21 is located on the lower side of the panel 2, and the second joint 22 is located on the upper side of the mounting plate. When disassembling, after removing the first joint 21, the panel 2 is pulled outward, and the upper part of the panel 2 (the second joint 22) can detach from the housing under the action of gravity, thereby facilitating the removal of the panel 2 from the housing 1.

[0051] It should be understood that the above description is for illustrative purposes and not for limitation. Many embodiments and applications beyond the provided examples will be apparent to those skilled in the art upon reading the above description. Therefore, the scope of this teaching should not be determined by reference to the above description, but rather by reference to the foregoing claims and the full scope of their equivalents. For purposes of completeness, all articles and references, including patent applications and publications, are incorporated herein by reference.
