[0029] Server racks are enclosures used to integrate and mount panels, modules, boxes, electronic components, devices, and mechanical parts and components, forming a complete unit. Power supply harnesses plug into and electrically connect to the server rack's board connectors to supply power to the server rack.

[0030] The existing power supply harness and board connector are fixed by friction and the elasticity of the metal terminals. When subjected to external force, the power supply harness is prone to detach from the board connector, causing the server rack to lose power.

[0031] This utility model proposes a power supply harness and connector assembly, which aims to improve the connection strength between the power supply harness and the board-end connector.

[0032] Please see Figure 1 In one embodiment of this utility model, the power supply harness 100 includes a base 10, a terminal module 20, a cable 30, a snap-fit ​​structure 40, and a drive member 50. The base 10 has a through hole; one end of the terminal module 20 passes through the through hole; the cable 30 is electrically connected to the other end of the terminal module 20; the middle part of the snap-fit ​​structure 40 is rotatably connected to a surface of the base 10, and one end of the snap-fit ​​structure 40 is used to snap-fit ​​with a board connector; the drive member 50 is disposed on the base 10 and drives the other end of the snap-fit ​​structure 40 to move one end of the snap-fit ​​structure 40 away from the base 10.

[0033] In this embodiment, the base 10 is a support structure for supporting various functional components and can be made of injection-molded rigid plastic. Its internal through holes provide an installation and positioning channel for the terminal module 20. The internal through holes of the base 10 form a radial constraint on the terminal module 20, preventing terminal misalignment during insertion and removal, which could lead to poor contact. The latching structure 40 is a lever mechanism with a rotating fulcrum, specifically made of injection-molded rigid plastic. Its middle part is connected to the base 10 via a rotating shaft 44 to form a fulcrum, and one end is provided with a latch 48 that engages with the corresponding groove 111 of the board connector. The driving component 50 is an operating component that controls the latching action, such as a rotary wrench structure. Its rotating shaft is connected to the base 10, and the protrusion 51 pushes the other end of the latching structure 40 to unlock it away from the corresponding groove 111. When the power supply harness 100 is plugged into the board connector, the latch 48 end of the latching structure 40 automatically engages into the groove 111 of the board connector under the action of the coil spring 45. When an external force is applied to the driving component 50, the driving component 50 pushes the other end of the latching structure 40, causing one end of the latching structure 40 to rotate around the pivot 44 and disengage from the groove 111. During this process, the latching structure 40 acts as a lever mechanism, amplifying and transmitting the torque input by the driving component 50 to one end of the latching structure 40, ensuring that the unlocking action is effortless and reliable. The cable 30 can be a collection of multiple electrical wires or a flexible copper busbar, etc., to achieve the effect of current conduction.

[0034] The technical solution of this utility model uses a snap-fit ​​structure 40 to fasten the power supply harness 100 to the board end connector, thereby improving the connection strength between the power supply harness 100 and the board end connector and preventing the connection between the two from failing due to external force.

[0035] Please see Figure 2 In an embodiment of this utility model, the driving member 50 is rotatably connected to one surface of the base 10, and a protrusion 51 is provided on one side of the driving member 50. The protrusion 51 is used to abut against the other side of the buckle structure 40, and a handle 52 is provided at the other end of the driving member 50.

[0036] In this embodiment, the drive member 50 is rotatably connected to one surface of the base 10 by means that the drive member 50 is mounted on the surface of the base 10 via a rotating shaft 44 or a hinge structure, allowing the drive member 50 to rotate around a fixed axis. This structure can convert rotational motion into linear displacement of the other end of the latching structure 40, and then into rotation of the latching structure 40. The protrusion 51 is a columnar or block-shaped protrusion provided on the side of the drive member 50. Its contact surface with the latching side can be designed as a slope or arc surface, converting rotational torque into a thrust on the latching through abutment. The handle 52 is a strip-shaped or ring-shaped extension structure provided at the end of the drive member 50. Its surface can be provided with anti-slip texture to provide a force fulcrum during manual operation. The protrusion 51 and the handle 52 can be located on the same straight line, or the straight line where the protrusion 51 is located can form an angle with the straight line where the handle 52 is located, so that the protrusion 51 can abut against the other end of the latching structure 40 by rotating the handle 52 by a small angle. When an external force is applied to the grip 52, the drive member 50 rotates around the rotation connection point. At this time, the protrusion 51 slides along the side of the buckle and generates displacement. Since the contact point between the protrusion 51 and the buckle is off the axis of rotation, a lever effect is formed, causing the buckle structure 40 to rotate around its own axis 44. During this motion transmission, the contact surface between the protrusion 51 and the buckle always maintains mechanical restraint, preventing the drive member 50 from disengaging from the buckle.

[0037] Please see Figure 2 and Figure 3 In an embodiment of this utility model, the snap-fit ​​structure 40 includes a base plate 41, the base plate 41 has an opening 43, and a side plate 42 is respectively protruding on opposite sides of the opening 43. Two protruding plates are spaced apart on one surface of the base 10. A connecting hole is respectively opened on the two protruding plates and the side plates 42. The rotating shaft 44 passes through the four connecting holes to rotatably connect the snap-fit ​​structure 40 to the base 10. A hook 48 is provided on the surface of the base plate 41 facing the base 10.

[0038] In this embodiment, the clearance opening 43 is a through opening in the middle of the substrate 41, which can be implemented using a rectangular or elliptical hole structure. The side plate 42 is a plate-like structure extending vertically from both sides of the clearance opening 43, which can be integrally formed with the substrate 41 using a stamping process, and is used to construct the support surface of the rotating connection mechanism. The protruding plate is a protrusion 51 structure provided on the surface of the base 10, which can be integrally formed with the base 10 using an injection molding process, and is used to cooperate with the side plate 42 to form a symmetrical rotation fulcrum. The rotating shaft 44 is a cylindrical component passing through the four connecting holes, which can be implemented using a stainless steel pin structure, and is used to establish the rotation axis 44 line between the snap-fit ​​structure 40 and the base 10. The hook 48 is a barb-shaped structure provided at the end of the substrate 41, which can be formed using a stamping and bending process, and is used to form a mechanical interlock with the corresponding slot of the board end connector.

[0039] Please see again Figure 2In an embodiment of this utility model, the buckle structure 40 further includes a baffle 46 and a coil spring 45. The baffle 46 is connected to the side of the two side plates 42 away from the base plate 41. The coil spring 45 passes through the rotating shaft 44. One end of the coil spring 45 abuts against the baffle 46, and the other end of the coil spring 45 abuts against a surface of the base 10.

[0040] In this embodiment, the baffle 46 and the two side plates 42 form a U-shaped frame structure. The coil spring 45 is sleeved on the rotating shaft 44, with one end in contact with the inner wall of the baffle 46 and the other end in contact with the surface of the base 10. When the driving member 50 applies an external force to make the snap-fit ​​structure 40 rotate around the rotating shaft 44, the coil spring 45 undergoes torsional deformation and stores elastic potential energy. When the external force is released, the coil spring 45 releases the elastic potential energy to make the snap-fit ​​structure 40 rotate in the opposite direction and return to the initial snap-fit ​​position. During this process, the baffle 46 serves as the fixed fulcrum of the coil spring 45, and the surface of the base 10 serves as the transmission surface of the elastic reaction force, jointly ensuring that the torsional force of the coil spring 45 acts directly on the rotation axis of the snap-fit ​​structure 40.

[0041] Please refer to it again. Figure 2 and Figure 3 In an embodiment of this utility model, a fin 47 is provided on the surface of the baffle 46 away from the base 10. The fin 47 is used to limit the rotation angle of the drive member 50.

[0042] In this embodiment, when the drive member 50 rotates around the base 10, its movement trajectory is restricted by the space of the fin 47. During rotation, the swing end of the drive member 50 contacts the side of the fin 47, at which point the fin 47 forms a rigid stop surface, preventing the drive member 50 from continuing to rotate. This prevents the rotation angle of the drive member 50 from exceeding the design range, avoiding problems such as the snap-fit ​​structure 40 becoming loose or unable to reset due to excessive rotation, and ensuring that the power supply harness 100 and the board connector always maintain a reliable locking state.

[0043] Please see Figure 4 and Figure 5 In an embodiment of this utility model, the base 10 includes a front base 11 and a rear base 12 that are detachably connected. The surfaces of the front base 11 and the rear base 12 are flush. The snap-fit ​​structure 40 is rotatably connected to the front base 11. The front base 11 has a through hole, through which the terminal module 20 passes and is electrically connected to the cable 30. The drive member 50 is rotatably connected to the rear base 12.

[0044] In this embodiment, the detachable front base 11 and rear base 12 refer to the mechanical connection between the front base 11 and rear base 12 via snap-fits or screws, facilitating individual disassembly of either the front base 11 or rear base 12 for maintenance and simplifying manufacturing. The flush surface arrangement means that the outer surfaces of the front base 11 and rear base 12 are on the same plane after connection, avoiding installation interference due to misalignment. The terminal module 20 passes through the through hole in the front base 11, the snap-fit ​​structure 40 is rotatably connected to the front base 11 for engaging with the board-end connector, and the drive component 50 is rotatably mounted on the rear base 12. The front and rear bases 12 solve the problem of inconvenient disassembly and maintenance caused by the complex structure of the base 10. Simultaneously, the separate layout isolates the movement paths of the snap-fit ​​structure 40 and the drive component 50, ensuring the stability of their linkage. The independent installation of the front base 11 and rear base 12 prevents interference between the electrical connection components and the mechanical drive components, improving maintenance efficiency and structural reliability.

[0045] Please refer to it again. Figure 5 In an embodiment of this utility model, the rear base 12 includes a fixing part 122, two lugs 121 and a clearance part 123. The fixing part 122 is detachably connected to the front base 11. The two lugs 121 are spaced apart on the upper surface of the fixing part 122. The driving member 50 is rotatably connected to the two lugs 121. The clearance part 123 is located on the lower surface of the fixing part 122 and has a stepped structure with the fixing part 122 to avoid the connection between the cable 30 and the terminal module 20.

[0046] In this embodiment, the two lugs 121 are symmetrical protrusions 51 structures provided on the upper surface of the fixing part 122. Specifically, they can be integrally formed with the fixing part 122 to provide a rotation fulcrum for the driving component 50 and ensure the smoothness of the driving operation. The clearance part 123 is a stepped extension structure located on the lower surface of the fixing part 122. Specifically, it can be realized by injection molding process. It is used to form a physical clearance space at the connection between the cable 30 and the terminal module 20, to avoid mechanical interference between the base 10 body and the connection of the cable 30, and to reduce the overall space occupied.

[0047] Please see Figure 6 In an embodiment of this utility model, the terminal module 20 includes a terminal base 21 and an annular terminal 22. One end of the terminal base 21 has a countersunk hole 211, and the annular terminal 22 is disposed in the countersunk hole 211. The other end of the terminal base 21 has a tongue 212 protruding from it and is electrically connected to the cable 30.

[0048] In this embodiment, the terminal block 21 is made of a conductive metal material, such as brass. One end of the terminal block 21 has a non-through countersunk hole 211. The annular terminal 22 is a metal component with an annular conductive structure, which can be made of copper alloy by stamping. It is used to form circumferential elastic contact with the pins of the board connector. The annular terminal 22 is embedded in the countersunk hole 211. The other end of the terminal block 21 is a tongue 212, which is used to weld to the cable 30. The current is transmitted to the pins of the board connector through the cable 30, the terminal block 21 and the annular terminal 22 to realize the conduction of current.

[0049] In an embodiment of this utility model, the upper surfaces of the front base 11 and the rear base 12 are provided with a communicating groove 111, two protruding plates are provided at the bottom of the groove 111, and the snap-fit ​​structure 40 is rotatably connected to the two protruding plates. The groove 111 is used to accommodate the snap-fit ​​structure 40.

[0050] In this embodiment, the grooves 111 provided in the front base 11 and the rear base 12 allow the buckle structure 40 to be partially accommodated in the grooves 111 when it rotates, so that the buckle structure 40 occupies less space when it rotates, and thus the thickness of the power supply harness 100 is reduced.

[0051] This utility model also proposes a connector assembly, which includes a power supply harness 100 and a board-end connector as described above. The board-end connector is inserted into the base 10, and one end of the snap-fit ​​structure 40 is engaged with the board-end connector.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
