Description

Technical Field

[0001] This invention relates to a PDU. Background Technology

[0002] PDU stands for Power Strip, a high-end power strip or power outlet used in server racks. A typical PDU consists of a housing and modules housed within it. A power cable runs through the housing and connects to each module. A traditional housing comprises an upper shell, a lower shell, and two end caps. The upper and lower shells are slidably connected together via grooves to form the main body, while the two end caps are fixed to the ends of the main body. One of the end caps has a through-hole for the power cable to pass through.

[0003] Generally, PDUs are fixed by mounting plates at both ends. Since the length of the PDU is fixed, the position of the mounting plates is also fixed. For some racks with fixed mounting holes, installing the PDU requires additional drilling, which is very inconvenient. Therefore, it is necessary to improve this method. Summary of the Invention

[0004] The purpose of this invention is to provide a PDU fixing mechanism that can be installed using existing holes on the rack, making installation more flexible.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PDU fixing mechanism, comprising an upper shell and a lower shell, wherein the upper shell and the lower shell are combined to form a PDU body, the two ends of the PDU body are provided with end caps, and the back of the lower shell is provided with a mounting groove, in which a slider is slidably connected, and the slider is provided with screw holes. During installation, the slider can be slid to a position directly aligned with the holes on the rack before installation. This allows for flexible installation even if the PDU is installed retrofitted, automatically matching the holes on the rack.

[0006] In a preferred embodiment of the present invention, the upper shell is provided with an installation port, and the PDU body is provided with a socket unit, the socket unit being directly opposite the installation port.

[0007] In a preferred embodiment of the present invention, the upper shell is provided with a sliding groove, the bottom of the sliding groove is provided with a lower hook, and the top of the upper shell is provided with an upper hook. The upper hook squeezes past the lower hook and then engages in the sliding groove. With this structure, during installation, the lower shell and upper shell are directly pressed together, causing the upper and lower hooks to press against each other, and then the lower hook engages in the sliding groove, thus achieving installation. This installation method eliminates the need to align the two ends, making it particularly convenient for installing very long PDUs.

[0008] In a preferred embodiment of the present invention, the upper shell is provided with a first mounting groove, the lower shell is provided with a second mounting groove, and the end cap is provided with a through hole. Screws pass through the through hole and are connected to the first and second mounting grooves. This is the connection method between the end cap and the upper and lower shells.

[0009] In a preferred embodiment of the present invention, a cover plate is further included, which is disposed on the outside of the PDU body, the component is disposed inside the PDU body, the screw passes through the component and is connected to the cover plate, and the mounting plate is clamped and fixed between the cover plate and the end cap.

[0010] In a preferred embodiment of the present invention, the mounting plate has a protrusion, and the cover plate has a recess, with the protrusion engaging with the recess. Thus, rotation of the mounting plate can cause the cover plate and the component to rotate synchronously.

[0011] In a preferred embodiment of the present invention, the inner wall of the corrugated hole is composed of crests and troughs evenly spaced circumferentially, with the number of crests and troughs being a multiple of 4. Having a multiple of 4 crests and troughs allows the mounting plate to be adjusted to angles that are multiples of 90 degrees, which is a commonly used angle during installation.

[0012] In a preferred embodiment of the present invention, the number of peaks and troughs is 12. Thus, with each rotation, the mounting plate changes angle by 30°.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: During installation, we can slide the slider to the position that aligns with the hole on the rack before installation. This way, even if the PDU is installed later, it can be matched automatically. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Please see Figure 1-4 The present invention provides a technical solution: a PDU fixing mechanism, including an upper shell 11 and a lower shell 12, wherein the upper shell 11 and the lower shell 12 are combined to form a PDU body 1, and end caps 2 are provided at both ends of the PDU body 1.

[0021] The upper shell 11 is provided with an installation port 113, and the PDU body 1 is provided with a socket unit 1a, which is directly opposite the installation port.

[0022] The back of the lower shell 12 is provided with a mounting groove 122, and a slider 7 is slidably connected in the mounting groove 122. The slider 7 is provided with a screw hole 71.

[0023] The upper shell 11 is provided with a first mounting groove 113, the lower shell 12 is provided with a second mounting groove 122, and the end cap 2 is provided with a through hole. Screws pass through the through hole and are connected to the first and second mounting grooves. This is the connection method between the end cap and the upper and lower shells.

[0024] The upper shell 11 is provided with a sliding groove 111, the bottom of the sliding groove 111 is provided with a lower hook 112, and the top of the upper shell 12 is provided with an upper hook 121. The upper hook 121 squeezes through the lower hook 112 and then gets into the sliding groove 111. With this structure, during installation, the lower shell and the upper shell are directly pressed against each other, causing the upper hook and the lower hook to press against each other, and then the lower hook gets into the sliding groove, thus achieving installation. This installation method does not require aligning the two ends for installation, and is especially convenient for some particularly long PDUs.

[0025] An mounting plate 3 is provided on the end cap 2. The mounting plate 3 is rotatably connected to the end cap 2 via a component 4. The end cap 2 has a corrugated hole 21 in the middle, and the component 4 is inserted into the corrugated hole 21. The inner wall of the corrugated hole 21 has crests and troughs evenly spaced circumferentially, and the number of crests and troughs is a multiple of 4. The fact that the number of crests and troughs is a multiple of 4 allows the mounting plate to be adjusted to angles that are multiples of 90 degrees, which is a commonly used angle during installation.

[0026] Specifically, there are 12 peaks and troughs. Thus, with each rotation, the mounting plate changes angle by 30°.

[0027] The component 4 is provided with several elastic protrusions 41 around its periphery, and the elastic protrusions 41 are in contact with the inner wall of the wave hole 21. In a stable state, the elastic protrusions are engaged in the trough of the wave hole.

[0028] It also includes a cover plate 5, which is disposed on the outside of the PDU body 1. The component 4 is disposed inside the PDU body 1. The screw 6 passes through the component 4 and is connected to the cover plate 5. The mounting plate 3 is clamped and fixed between the cover plate 5 and the end cap 2.

[0029] The mounting plate 3 has a protrusion 31, and the cover plate 5 has a recess 51. The protrusion 31 is engaged with the recess 51. In this way, the rotation of the mounting plate can drive the cover plate and the component to rotate synchronously.

[0030] During installation, we can slide the slider to the position that aligns with the hole on the rack before installation. This way, even if the PDU is installed later, it can be matched automatically.
