Description

Technical Field

[0001] This application relates to the field of electrical connections, and more particularly to a packaging structure for 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] PDUs (Power Distribution Units) are highly susceptible to damage during logistics and warehousing due to their numerous copper busbars, switches, and connector modules caused by drops, vibrations, or stacking compression. Existing technologies typically employ single-material solutions such as all-foam, all-honeycomb paper, or all-corrugated cardboard. While all-foam offers excellent cushioning, it is bulky, expensive, and environmentally unfriendly; all-honeycomb paper is lightweight and inexpensive, but its impact resistance at the ends (especially those with connecting wires) is significantly insufficient; all-corrugated cardboard falls somewhere in between, still presenting a trade-off between excessive weight and insufficient strength. Therefore, the market urgently needs a PDU packaging solution that can provide reliable protection for critical stress points while maintaining overall lightweight and cost-effectiveness.

[0004] 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.

[0010] Preferably, the first covering mechanism includes a first upper limit portion and a first lower limit portion, wherein the first upper limit portion covers the first lower limit portion.

[0011] Preferably, the rigid support mechanism includes a first support unit disposed within the first covering mechanism. The first support unit includes a first upper support portion disposed within the first upper limit portion and a first lower support portion disposed within the first lower limit portion.

[0037] Referring to Figure 1, the PDU power supply includes a PDU housing with a chamber for accommodating the PDU power supply. The PDU housing has a first end and a second end along its length. The second end of the PDU housing 11 is connected to one end of a connecting line 12. The other end of the connecting line 12 is provided with a connector 13 for external connection. In packaging, the PDU housing 11 and the connecting line 12 are both housed within the packaging structure. In the housed state, the connecting line 12 is bent at its connection point with the second end of the PDU housing 11 to form a corner, then extends towards the first end, and after reaching the first end of the PDU housing 11, it is bent again by 180 degrees and extends towards the second end of the PDU housing 11. Finally, the connector 13 of the PDU power supply is generally located in the middle of the PDU housing 11.

[0038] Referring to Figure 2, the outer casing 2 includes a lower cover 21 and an upper cover 22. After packaging is completed, the upper cover 22 is placed on top of the lower cover 21, thus completing the sealing process and finalizing the packaging structure.

[0039] Referring to Figures 2 and 3, along the length of the PDU housing 11, starting from the first end of the PDU housing 11, a first covering mechanism 3, a third covering mechanism 5, and a second covering mechanism 4 are sequentially arranged inside the lower cover 21. The first covering mechanism 3, the third covering mechanism 5, and the second covering mechanism 4 are all made of honeycomb cardboard.

[0040] Referring to Figure 4, generally, the first covering mechanism 3 is located at the end of the first end of the PDU housing 11. The second covering mechanism 4 is located at the second end of the corner of the connecting line. The third covering mechanism 5 is located between the first covering mechanism 3 and the second covering mechanism 4. Preferably, the third covering mechanism 5 is located at the midpoint of the length direction of the lower cover 21. Referring to Figures 7, 9, and 11, a first receiving groove 81 for the PDU housing 11 to pass through is formed on one side of the interior of the first covering mechanism 3, the second covering mechanism 4, and the third covering mechanism 5. A second receiving groove 82 higher than the first receiving groove 81 is provided on the other side of its interior, and the connecting line 12 can pass through and be placed in the second receiving groove 82. Preferably, the second receiving groove 82 of the third covering mechanism 5 is substantially the same size as the connector 13, thereby limiting the connector 13.

[0041] Referring to Figures 2 and 3, preferably, considering the strength of the installation, a partition portion 9 may be provided between the second covering mechanism 4 and the third covering mechanism 5. This partition portion 9 has only the second receiving groove 82, and the partition portion 9 only covers the second receiving groove 82 in the projection toward the cross section perpendicular to its length. This partition portion 9 may also be made of honeycomb cardboard.

[0042] Referring to Figures 4 and 8, at the first end of the first covering mechanism 3 (the end facing the first end of the outer shell 2 during installation), the rigid support mechanism includes a first support unit 61 disposed within the first covering mechanism 3. When the PDU is placed on the first covering mechanism 3, the first support unit 61 is located between the first end of the outer shell 2 and the first end face of the PDU housing 11 along the length direction of the outer shell 2. In a preferred embodiment, when the first covering mechanism 3 is in the installed state, the first support unit 61 can abut against the inner wall of the outer shell 2 to improve strength.

[0043] Referring to FIG7, in this embodiment, the first covering mechanism 3 includes a first upper limit portion 31 and a first lower limit portion 32, wherein the first upper limit portion 31 covers the upper limit portion 32. The first support unit 61 includes a first upper support portion 611 disposed within the first upper limit portion 31 and a first lower support portion 612 disposed within the first lower limit portion 32.

[0044] In an optional embodiment, the first covering mechanism 3 is provided with a third receiving groove (not shown in the figure) in the direction of the first receiving groove 81 and the second receiving groove 82 toward the first end of the outer shell 2. The first upper support portion 611 and the first lower support portion 612 are received in the third receiving groove and may include a plurality of planar rigid cardboard sheets stacked along the height direction. The projection of the first upper support portion 611 and the first lower support portion 612 toward a cross section perpendicular to its length covers the first receiving groove 81 and the second receiving groove 82.

[0045] Referring to Figures 9 and 10, at the first end of the second covering mechanism 4 (the corner facing the connecting line during installation, and the end away from the second end of the outer casing 2), the rigid support mechanism includes a second support unit 62 disposed within the second covering mechanism 4. The second support unit 62 includes multiple planar rigid plates stacked along the height direction. When the PDU is placed on the second covering mechanism 4, the second support unit 62 is located along the length direction of the outer casing 2 between the second end of the outer casing 2 and the corner of the connecting line.

[0046] Specifically, the second covering mechanism 4 includes a second upper limit part 41 and a first lower limit part 32, wherein the second upper limit part 41 is disposed above the second lower limit part 42 by a stepped surface.

[0047] The second support unit 62 includes a second lower support portion 622 disposed on the second lower limit portion 42 and a second upper support portion 621 disposed on the second upper limit portion 41. Preferably, the second lower support portion 622 and the second upper support portion 621 are disposed within the first receiving groove 81. In this embodiment, both the second upper support portion 621 and the second lower support portion 622 may include a plurality of planar rigid cardboard sheets stacked along the height direction.

[0048] Preferably, the second covering mechanism 4 has a stop portion 43 formed at the second end facing the outer shell 2, the stop portion 43 being able to cover the second receiving groove 82 in the projection of the cross section perpendicular to the length.

[0049] Specifically, the installation method of this application embodiment includes the following steps: The rigid support mechanism is fixed to the first covering mechanism 3 and / or the second covering mechanism 4 by means of adhesive or other methods; The first lower limit part 32 in the first covering mechanism 3, the third lower limit part 52 in the third covering mechanism 5, and the second lower limit part 42 in the second covering mechanism 4 are placed in the lower cover 21 of the outer shell 2; The PDU power supply 1 is placed in the first receiving slot 81 and the second receiving slot 82; The first upper limit part 31 of the first covering mechanism 3 is placed on the first lower limit part 32 of the first covering mechanism 3, the third upper limit part 51 of the third covering mechanism 5 is placed on the third lower limit part 52 of the third covering mechanism 5, and the second upper limit part 41 of the second covering mechanism 4 is placed on the second lower limit part 42 of the second covering mechanism 4. After the upper cover 22 is placed on the lower cover 21, it is sealed.

[0050] With the above structure, the packaging structure of the PDU power supply 1 in this embodiment of the application significantly improves the strength of key stress-bearing parts such as the end and cable outlet through the composite design of "honeycomb paper body and rigid cardboard partial layering reinforcement", while controlling the overall weight and cost.
