Description

Technical Field

[0001] This application relates to the field of socket power cord installation technology, and in particular to a PDU cable sheath structure. Background Technology

[0002] A PDU is a rack-mounted power distribution unit that provides power to rack-mounted electrical equipment. The PDU is connected to a power cord, which serves as its power source.

[0003] Currently, the connection point between the power cord and the PDU is equipped with a sheath structure, which provides support and protection for the power cord.

[0004] However, the sheath structure in the relevant technology cannot limit the power cord, which can easily cause the connection end between the power cord and the PDU to twist around its own axis and be pulled out along the axial direction, thereby affecting the reliability of the power cord supplying power to the PDU.

[0005] Among the aforementioned technologies, there is a defect that the power cord is prone to twisting, which affects the reliability of power supply to the PDU. Utility Model Content

[0006] To address the issues of power cords being prone to twisting and being pulled out along the axial direction, thus affecting the reliability of power supply to the PDU, this application provides a PDU cable sheath structure.

[0007] The PDU cable sheath structure provided in this application adopts the following technical solution:

[0008] A PDU cable protection sleeve structure is used to limit the relative positioning of the power cord and the PDU. The PDU cable protection sleeve structure includes: an end cover, the end cover including an end cover body mounting hole, a limiting groove, and two snap-fit ​​parts. The end cover body is used to mate with the end face of the PDU, so that the end cover body and the PDU are relatively fixed. The mounting hole is opened in the middle of the end cover body and penetrates the end cover body. The limiting groove is opened in the circumference of the mounting hole. The two snap-fit ​​parts are evenly distributed in the circumference of the mounting hole. The first end of the snap-fit ​​part is connected to one side of the mounting hole, and the second end of the snap-fit ​​part extends along the axial direction of the mounting hole. The snap-fit ​​part is set with a first preset arc. A protective sleeve includes: The device comprises a sheath body, a mounting portion, and a limiting portion. The sheath body is fitted around the outer periphery of the power cord. The mounting portion is recessed in the outer peripheral surface of the sheath body and passes through the mounting hole. The limiting portion protrudes from the outer peripheral surface of the mounting portion and aligns with the limiting groove to restrict relative rotation between the sheath body and the end cap body. Two snap-fit ​​portions are fitted around the outer periphery of the mounting portion. The area of ​​the circle enclosed by the first ends of the two snap-fit ​​portions is larger than the area of ​​the circle enclosed by the second ends of the two snap-fit ​​portions. The diameter of the first end of the mounting portion is larger than the diameter of the second end of the mounting portion. The two snap-fit ​​portions clamp the outer periphery of the mounting portion, so that the snap-fit ​​portions are embedded in the sheath body.

[0009] By adopting the above technical solution, the end cap is used to connect the PDU, and the cooperation between the end cap and the protective sleeve realizes the limitation of the power cord, preventing the power cord from rotating and affecting the stable power supply to the PDU; the end cap body is used to align and assemble with the PDU for easy installation; the protective sleeve body is sleeved on the outer periphery of the power cord, on the one hand to protect the power cord, and on the other hand, it can limit the power cord along the direction perpendicular to the mounting hole by cooperating with the mounting part, and limit the rotation of the protective sleeve body by cooperating with the limiting part and the limiting groove, thereby achieving the purpose of limiting the rotation of the power cord and improving the stability of power supply; the two snap-fit ​​parts realize the clamping effect of the mounting part, so that the protective sleeve body can be fixed to the end cap body, limiting the movement of the power cord along the axial direction, thereby preventing the power cord from being pulled out from the end cap and the PDU.

[0010] Optionally, along the axial direction of the mounting hole, the snap-fit ​​portion is set with a second preset arc, so that the middle part of the snap-fit ​​portion protrudes in a direction away from the axis of the mounting hole, and the snap-fit ​​portion can deform to snap onto the outer periphery of the mounting portion.

[0011] By adopting the above technical solution, the contact area between the snap-fit ​​part and the mounting part can be reduced, thereby reducing friction and facilitating the deformation of the snap-fit ​​part, thus enabling the clamping and tightening of the mounting part and improving the reliability of the limit.

[0012] Optionally, two limiting grooves are provided, the two limiting grooves are symmetrically arranged around the mounting hole, and the two snap-fit ​​portions are symmetrically arranged on both sides of the straight line where the two limiting grooves are located.

[0013] By adopting the above technical solution, the limiting and fixing effect of the sheath body can be optimized, which helps to improve the stability of the power cord.

[0014] Optionally, the mounting portion is recessed on the outer periphery of the sheath body, such that the first end of the mounting portion is provided with a first locking end face that forms a first angle with the axis of the sheath body, and the second end of the mounting portion is provided with a second locking end face that forms a second angle with the axis of the sheath body. Along the axial direction of the sheath body, the first locking end face is used to lock the first end of the locking portion, and the second locking end face is used to lock the second end of the locking portion.

[0015] By adopting the above technical solution, the first and second locking end faces can be used to limit the sheath body along the axial direction, thereby improving the fixing effect of the power cord.

[0016] Optionally, the snap-fit ​​portion includes a first part and a second part, the first ends of the first part and the second part are connected, and the second ends of the first part and the second part are spaced apart.

[0017] By adopting the above technical solution, it is helpful to increase the deformation of the snap-fit ​​part, thereby achieving a reliable clamping effect on the mounting part.

[0018] Optionally, the inner diameter of the sheath body matches the outer diameter of the power cord.

[0019] By adopting the above technical solution, it is possible to achieve compatibility with power lines of different outer diameters without reducing the outer diameter of the sheath body, thereby improving the applicability of the end cap.

[0020] Optionally, the end cap includes a connecting portion disposed on the end cap body, the connecting portion being used to connect the PDU.

[0021] By adopting the above technical solution, the end cap body and the PDU can be aligned and fitted through the connecting part, so that the end cap body can be limited on the PDU.

[0022] Optionally, the connecting part includes a connecting hole, which is used to connect the PDU via bolts.

[0023] By adopting the above technical solution, bolts are used to connect the connecting part to the PDU, so that the end cover body can be reliably connected to the PDU.

The protrusion has a positioning part, the positioning part extends in a direction perpendicular to the axial direction of the mounting hole, the protrusion is used to cooperate with the bent plate, the positioning part is used to snap the bent plate, and the bent plate is used to connect the end cap body to the fixing structure.

[0025] By adopting the above technical solution, the protrusion can limit the bending plate, so that the bending plate can connect the end cover body and the PDU, thereby installing the PDU on the fixed structure through the bending plate and improving the convenience of installation.

[0026] Optionally, the end cap body is integrally formed. Along the axial direction of the mounting hole, the positioning part is spaced apart from the plane where the mounting hole is located. The end cap body is provided with a through hole. The snap-fit ​​part is provided with a blocking part on the side away from the axis of the mounting hole. The blocking part is provided on the side of the through hole close to the mounting hole, so that the blocking part is located between the mounting hole and the through hole. The blocking part has a groove-shaped structure and extends along the axial direction of the mounting hole to block the probe.

[0027] By adopting the above technical solution, the through hole facilitates the integral molding of the end cap body and its protrusion. The setting of the blocking part can reduce the risk of the probe coming into contact with the charged component when the probe detects the through hole, thus affecting practical safety.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The end cap is used to connect the PDU and, through its cooperation with the protective sleeve, limits the power cord to prevent rotation and thus ensure stable power supply to the PDU. The end cap body is used for alignment and assembly with the PDU for easy installation. The protective sleeve body is fitted around the power cord, serving two purposes: protecting the power cord and limiting its movement perpendicular to the mounting hole through the engagement of the mounting part. Furthermore, the engagement of the limiting part with the limiting groove restricts the rotation of the protective sleeve body, thereby limiting power cord rotation and improving power supply stability. Two snap-fit ​​parts clamp the mounting part, fixing the protective sleeve body to the end cap body and restricting the power cord's movement along the axial direction, thus preventing the power cord from being pulled out of the end cap and the PDU.

[0043] The following is combined with Figure 1 -Appendix Figure 9This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings, and are used only for ease of description and simplification of operation, not to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0045] like Figure 1 As shown in the figure, this application discloses a PDU cable sheath structure (hereinafter referred to as "cable sheath structure"). The cable sheath structure includes an end cap 1 and a protective sleeve 2, which are used to limit the relative positioning of the power cord 100 and the PDU. The PDU is a housing structure with a rectangular cross-section and contains electrical components.

[0046] like Figure 1 and Figure 2 As shown, the end cap 1 is used to connect the PDU and, through the cooperation of the end cap 1 and the protective sleeve 2, limits the power cord 100, preventing the power cord 100 from rotating and affecting the stable power supply to the PDU. The end cap 1 includes an end cap body 11, a connecting part 12, a mounting hole 13, and a limiting groove 14. The end cap body 11 is used to align with the end face of the PDU for easy installation. The connecting part 12 is provided on the end cap body 11 and is used to connect the PDU, so that the end cap body 11 and the PDU are relatively fixed. The limiting groove 14 is formed in the circumference of the mounting hole 13 and protrudes in a direction away from the axis of the mounting hole 13.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, the protective sleeve 2 includes a sleeve body 21, a mounting part 22, and a limiting part 23. The sleeve body 21 is fitted around the outer periphery of the power cord 100 to protect the power cord 100. A mounting hole 13 is formed in the middle of the end cap body 11 and penetrates through the end cap body 11. The mounting part 22 is recessed on the outer peripheral surface of the sleeve body 21 and passes through the mounting hole 13. The mounting part 22 can cooperate with the mounting hole 13 to limit the power cord 100 in a direction perpendicular to the mounting hole 13. The limiting part 23 protrudes from the outer peripheral surface of the mounting part 22 and is aligned with the limiting groove 14 to limit the relative rotation between the sleeve body 21 and the end cap body 11, thereby limiting the rotation of the power cord 100 and improving power supply stability.

[0048] Optionally, the connecting part 12 includes a connecting hole 121, which connects to the PDU via bolts, so that the end cap body 11 can be reliably connected to the PDU.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the end cap 1 further includes two snap-fit ​​portions 15, which are evenly distributed around the mounting hole 13. The first end of each snap-fit ​​portion 15 connects to one side of the outer peripheral wall of the mounting hole 13, and the second end of each snap-fit ​​portion 15 extends along the axial direction of the mounting hole 13. The snap-fit ​​portions 15 are set with a first preset arc, allowing them to fit over the outer periphery of the mounting portion 22, optimizing the fixing effect. The area of ​​the circle enclosed by the first ends of the two snap-fit ​​portions 15 is larger than the area of ​​the circle enclosed by the second ends of the two snap-fit ​​portions 15, and the diameter of the first end of the mounting portion 22 is larger than the diameter of the second end of the mounting portion 22. This allows for clamping by engaging the first end of the snap-fit ​​portion 15 with the first end of the mounting portion 22 and fitting the second end of the snap-fit ​​portion 15 against the outer periphery of the second end of the mounting portion 22. The mounting portion 22 can be a circumferential surface with one or more inclined segments, allowing the snap-fit ​​portions 15 to clamp the outer periphery of the mounting portion 22. The mounting part 22 is clamped by two snap-fit ​​parts 15 so that the sheath body 21 can be fixed to the end cover body 11, restricting the movement of the power cord 100 along the axial direction, thereby preventing the power cord 100 from being pulled out from the end cover 1 and the PDU, which would affect power supply and safety of use.

[0050] Optionally, along the axial direction of the mounting hole 13, the engaging portion 15 is set with a second preset curvature, causing the middle part of the engaging portion 15 to protrude away from the axis of the mounting hole 13. This reduces the contact area between the engaging portion 15 and the mounting portion 22, thereby reducing friction and facilitating deformation of the engaging portion 15. The engaging portion 15 can deform to engage with the outer periphery of the mounting portion 22, thereby achieving a clamping and tightening effect on the mounting portion 22 and improving the reliability of the limiting position. The first and second preset curvatures are set as needed.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, two limiting grooves 14 are provided, and the two limiting grooves 14 are symmetrically arranged around the mounting hole 13. Two snap-fit ​​parts 15 are symmetrically arranged on both sides of the line where the two limiting grooves 14 are located, which can optimize the limiting and fixing effect on the sheath body 21 and help improve the stability of the power cord 100.

[0052] Optionally, the snap-fit ​​portion 15 includes a first split body 151 and a second split body 152. The first ends of the first split body 151 and the second split body 152 are connected to improve the overall integrity, so as to facilitate the tight clamping and fixing of the power cord 100. The second ends of the first split body 151 and the second split body 152 are spaced apart. By being relatively separated, deformation is facilitated, which helps to increase the deformation amount of the snap-fit ​​portion 15, thereby achieving a reliable clamping effect on the mounting portion 22.

[0053] like Figure 4 , Figure 5 and Figure 6 As shown, optionally, the mounting portion 22 is recessed on the outer periphery of the sheath body 21, such that the first end of the mounting portion 22 has a first locking end face 221 set at a first angle to the axis of the sheath body 21, and the second end of the mounting portion 22 has a second locking end face 222 set at a second angle to the axis of the sheath body 21. Along the axial direction of the sheath body 21, the first locking end face 221 is used to lock the first end of the locking portion 15, and the second locking end face 222 is used to lock the second end of the locking portion 15. The first locking end face 221 and the second locking end face 222 limit the sheath body 21 along the axial direction, improve the fixing effect of the power cord 100, and prevent it from being pulled out. The first preset angle and the second preset angle are set as needed. For example, both the first locking end face 221 and the second locking end face 222 can be perpendicular to the outer peripheral surface of the sheath body 21.

[0054] like Figure 6 and Figure 7 As shown, optionally, the inner diameter of the sheath body 21 matches the outer diameter of the power cord 100, which helps to match with power cords 100 of different outer diameters without changing the outer diameter of the sheath body 21, so that power cords 100 of different diameters can be quickly replaced without replacing the end cap 1, thereby improving the applicability of the end cap 1.

[0055] The protective sleeve 2 is injection molded on the outer periphery of the power cord 100. The protective sleeve 2 can be made of rubber to have a certain degree of flexibility so that the power cord 100 can be bent and moved. The end cap 1 can be made of plastic so that the mounting part 22 can be inserted into the snap-fit ​​part 15. The insertion of the mounting part 22 and the clamping of the mounting part 22 are achieved by the deformation of the snap-fit ​​part 15.

[0056] like Figure 2 , Figure 8 and Figure 9 As shown, optionally, the end cap body 11 has a protrusion 111, and a mounting hole 13 is formed on the protrusion 111. The protrusion 111 protrudes in a direction away from the second end of the snap-fit ​​part 15 along the axial direction of the mounting hole 13, so that the second end of the protrusion 111 and the snap-fit ​​part 15 are respectively located on both sides of the mounting hole 13. The protrusion 111 has a positioning part 112, which extends in a direction perpendicular to the axial direction of the mounting hole 13. The protrusion 111 is used to cooperate with the bent plate 3, and the positioning part 112 is used to snap the bent plate 3. The bent plate 3 is used to connect the end cap body 11 to the fixing structure.

[0057] The bent plate 3 is an L-shaped piece. Its first end fits against the end cover body 11, and its second end fits against the bottom surface of the PDU when stored, reducing space occupation and improving aesthetics. In use, by rotating the first end 180°, the second end of the bent plate 3 extends out, allowing the PDU to be fixed in place. The protrusion 111 limits the movement of the bent plate 3, facilitating its connection to the end cover body 11 and the PDU. This allows the PDU to be installed on cabinets, walls, or other fixed structures, improving installation convenience.

[0058] like Figure 2 , Figure 8 and Figure 9 As shown, optionally, the end cap body 11 is integrally formed. Along the axial direction of the mounting hole 13, the positioning part 112 is spaced apart from the plane containing the mounting hole 13. Along the axial direction of the mounting hole 13, the bent plate 3 is positioned between the protrusion 111 and the end cap body 11. During the forming process of the end cap body 11, a through hole 113 is provided on the end cap body 11, which facilitates the integral forming of the end cap body 11 and the protrusion 111. A blocking part 16 is provided on the side of the snap-fit ​​part 15 away from the axis of the mounting hole 13. The blocking part 16 is located on the side of the through hole 113 closest to the mounting hole 13, positioned between the mounting hole 13 and the through hole 113. The blocking part 16 has a groove-like structure and extends along the axial direction of the mounting hole 13 to block the probe. The blocking part 16 reduces the risk of the probe contacting a live component when detecting through the through hole 113, thus minimizing safety concerns.

[0059] It is understandable that the cable sheath structure also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the cable sheath structure can operate normally; the shape, size, material and number of each part of the cable sheath structure can be determined as needed, as long as the corresponding functions can be achieved.

[0060] The implementation principle of the PDU cable sheath structure in this application embodiment is as follows: the end cover body 11 is aligned and assembled with the PDU, and the relative fixation of the end cover body 11 and the PDU is achieved through the connecting part 12. The sheath body 21 is sleeved on the outer periphery of the power cord 100. The mounting part 22 cooperates with the mounting hole 13 to limit the power cord 100 in the direction perpendicular to the mounting hole 13. The rotation of the sheath body 21 is restricted by the cooperation of the limiting part 23 and the limiting groove 14, thereby achieving the purpose of restricting the rotation of the power cord 100. The movement of the protective sleeve 2 along the axial direction is restricted by the cooperation of the snap-fit ​​part 15 and the mounting part 22, so that the power cord 100 fixedly connected in the protective sleeve 2 will not be pulled out, thus improving the power supply stability.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
