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] Previously, the connection between the upper and lower shells was fixed by a sliding connection. Specifically, one end of the upper and lower shells needed to be aligned, the protrusions and grooves on both needed to be aligned, and then they needed to be inserted into each other. This installation method was troublesome for some PDUs with relatively long shells, so it was necessary to improve it. Summary of the Invention

[0004] The purpose of this invention is to provide a PDU housing connection structure that makes installation more convenient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PDU shell connection structure, comprising an upper shell and a lower shell, wherein the upper shell and the lower shell are combined into a body, and end caps are provided at both ends of the body. A sliding groove is provided on the upper shell, a lower hook is provided at the bottom of the sliding groove, and an upper hook is provided at the top of the upper shell. The upper hook squeezes past the lower hook and then engages with the sliding groove. 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 engages with the sliding groove, thus achieving installation. This installation method eliminates the need to align the two ends for installation, making it particularly convenient for some very long PDUs.

[0006] 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.

[0007] In a preferred embodiment of the present invention, a cover plate is further included, which is disposed on the outside of the body, the component is disposed inside the 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.

[0008] 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.

[0009] 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.

[0010] 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°.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: In a stable state, the elastic protrusion engages within the trough of the wave hole. When adjustment is needed, the mounting plate can be rotated, causing the component to rotate along with it, sliding the elastic protrusion out of the trough, over a wave crest, and into the next trough, thus achieving stability again. This allows for adjustment of the mounting plate's angle, adapting to different installation positions and making installation more flexible. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0018] Please see Figure 1-4 The present invention provides a technical solution: a PDU shell connection structure, including an upper shell 11 and a lower shell 12, wherein the upper shell 11 and the lower shell 12 are combined into a body 1, and end caps 2 are provided at both ends of the body 1.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] Specifically, there are 12 peaks and troughs. Thus, with each rotation, the mounting plate changes angle by 30°.

[0023] 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.

[0024] It also includes a cover plate 5, which is disposed on the outside of the body 1. The component 4 is disposed inside the 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.

[0025] 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.
