[0006] The base includes a rear seat, a partition, and two front protruding walls. Both front protruding walls extend forward from the partition, and the rear seat extends rearward from the partition. A slot is formed between the two front protruding walls for inserting external components. Two symmetrical lateral openings and a bottom opening connecting the two lateral openings are provided between the opposite side walls of the rear seat.

[0011] In one embodiment, a groove is formed on each of the two side walls of the side cover section, and a protrusion is formed on each of the two side walls of the lateral opening. Each protrusion is slidably connected to the groove wall of the groove to confine the side cover section within the lateral opening.

[0012] In one embodiment, the terminal group includes two terminal pieces, with the ends of the two terminal pieces offset from the partition.

[0013] In one embodiment, the end of the terminal piece away from the partition is bent toward the slot to form a bent portion, and the bent portion forms a protrusion toward the slot.

[0032] With the rapid development of servers, the demand for high-current connectors has grown rapidly. These connectors are typically placed inside server racks and are needed to perform high-power cable switching or branching within a limited space.

[0033] In practical applications, due to differences in the layout of cabinets, modules, or cable trays, the cable exit direction of connectors is usually towards one of the left or right sides to avoid interference with surrounding devices and shorten wiring length. However, the opening direction of existing connectors is determined before leaving the factory, and it is not possible to adjust the opening to the left or right as needed in actual application scenarios, which is inconvenient to use.

[0034] To solve the above problems, this utility model proposes a solution. Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 This is a schematic diagram of the structure of an embodiment of the high-current connector 1000 provided by this utility model.

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This utility model proposes a high-current connector 1000, including a base 1, two terminal groups 2, and a back cover 3. The base 1 includes a rear seat 11, a partition 12, and two front protruding walls 13. Both front protruding walls 13 extend forward from the partition 12, and the rear seat 11 extends backward from the partition 12. A slot 13a is formed between the two front protruding walls 13 for external components to be inserted. Two symmetrical lateral openings 11a and a bottom opening 11b connecting the two lateral openings 11a are provided between the opposite side walls of the rear seat 11. Multiple locking holes 11c are formed on the opposite side walls of the rear seat 11. The two terminal groups 2 pass through the same lateral opening 11a into the interior of the front protruding wall 13 and are exposed in the slot 13a. Buckles 311 are formed on both sides of the back cover 3, and each buckle 311 is engaged in the corresponding locking holes 11c on the opposite side walls of the rear seat 11. The back cover 3 is configured to cover the other lateral opening 11a and the bottom opening 11b.

[0036] The slot 13a is formed between two protruding walls 13, and can be implemented using a U-shaped cavity structure to accommodate the insertion of external components. The bottom opening 11b refers to the opening formed in the bottom wall of the rear seat 11 away from the partition 12, and can be implemented using a rectangular or trapezoidal structure, for the snap-fit ​​fixing of the back cover 3. The side openings 11a refer to the openings formed on opposite side walls of the rear seat 11, and can be formed by stamping or injection molding processes, for the assembly and connection of the terminal group 2. The bottom opening 11b communicates with the side openings 11a, so that when the back cover 3 covers the bottom opening 11b, it can simultaneously cover the adjacent side openings 11a, thereby forming a continuous closed space. The latches 11c are distributed on the side walls of the rear seat 11 for fixing the latches 311 of the back cover 3. The latches 311 of the back cover 3 can be barbed components, which can be detachably connected to the latches 11c through elastic deformation.

[0037] In the technical solution of this utility model, the base 1 separates the insertion area and the wire harness area through the partition 12. The terminal group 2 extends through the through hole of the partition 12 to the slot 13a to form a contact point. When an external component is inserted into the slot 13a, it forms an electrical connection with the terminal group 2. The back cover 3 cooperates with the buckle 311 and the card hole 11c to selectively cover either side opening 11a and bottom opening 11b, so that the wire harness 5 can be led out from the other side. During installation, the back cover 3 is installed on the left or right side according to the cabinet space layout, correspondingly closing the opening on that side and leaving the opposite side as the cable outlet. Through the symmetrical side openings 11a on both sides and the detachable back cover 3 structure, the cable outlet direction can be selected to the left or right side according to actual needs, avoiding interference between the cable and surrounding devices. The installer can select the left or right outlet according to the space constraints on site, thereby realizing flexible adjustment of the cable outlet direction. Meanwhile, the snap-fit ​​connection between the back cover 3 and the base 1 simplifies the disassembly and assembly process, allowing for orientation switching without the need for special tools. The detachable design of the back cover 3 enables bidirectional compatibility of the connector, further enhancing the ease of installation of the high-current connector 1000.

[0038] Please refer to Figure 1 and Figure 2 In one embodiment of this utility model, the bottom opening 11b is connected to the two side openings 11a respectively.

[0039] Traditional connectors have independent bottom openings 11b and side openings 11a, which limits the back cover 3 to a single direction, making it inflexible for different wiring scenarios. This application, however, uses a connecting opening design, allowing the back cover 3 to be installed freely according to the routing of the wiring harness 5. This significantly improves spatial adaptability, solves the wiring interference problem caused by the fixed opening direction of existing connectors, and allows users to adjust the outgoing direction of the wiring harness 5 according to the actual layout of the cabinet or module, avoiding collisions with surrounding devices. It also shortens cable length and improves space utilization.

[0040] Please refer to Figure 1 , Figure 2 as well as Figure 3 In one embodiment of the present invention, the back cover 3 includes a top cover section 31 and a side cover section 32 that are bent and connected. Both sides of the top cover section 31 are provided with buckles 311, and both side walls of the rear seat 11 adjacent to the side opening 11a are provided with locking holes 11c. The top cover section 31 is configured to cover the bottom opening 11b, and the side cover section 32 is configured to cover one side opening 11a.

[0041] The bending connection refers to the top cover section 31 and the side cover section 32 forming an integral structure through a bending process. Specifically, it can be achieved by a stamping process, so that the top cover section 31 and the side cover section 32 form a right angle or obtuse angle connection relationship, thereby covering openings in different directions at the same time during installation.

[0042] Specifically, the top cover section 31 is inserted into the locking holes 11c on both sides of the rear seat 11 via the buckles 311 on both sides, so that the top cover section 31 completely covers the bottom opening 11b, preventing foreign objects from entering the insertion area. The side cover section 32 forms an angle with the top cover section 31 through a bent connection, allowing it to be inserted into the side opening 11a, covering the opening and fixing the wire harness 5. During installation, the bent structure of the top cover section 31 and the side cover section 32 allows the back cover 3 to be assembled in a separate manner. During operation, it is only necessary to align the buckles 311 with the locking holes 11c and press them to complete the fixation, without the need for additional fasteners.

[0043] The symmetrical design of the buckle 311 and the clip 11c allows users to freely choose the left or right exit direction according to the layout of the cable harness 5. When adjusting the exit direction, simply remove and flip the back cover 3 and then install it to change the exit direction, which improves the convenience of adjusting the exit direction.

[0044] Please refer to Figure 1 , Figure 2 as well as Figure 3 In one embodiment of the present invention, a groove 32a is formed on both sides of the side cover section 32, and a protrusion 111 is formed on both sides of the side opening 11a. Each protrusion 111 is slidably connected to the groove wall of a groove 32a to limit the side cover section 32 within the side opening 11a.

[0045] The groove 32a refers to the groove structure provided on both sides of the side cover section 32, which is used to guide the protrusion 111 to slide along a specific path. The protrusion 111 refers to the protruding structure extending outward from both sides of the side opening 11a, which can be implemented as a rectangular protrusion, and is used to form a sliding fit with the groove 32a. The sliding connection refers to the movable fit formed after the protrusion 111 is embedded in the groove 32a, which can be implemented by clearance fit or transition fit, and is used to limit the displacement of the side cover section 32 in the vertical direction.

[0046] Specifically, during the assembly of the back cover 3, the protrusion 111 is guided into the groove along the extending direction of the slide groove 32a, and the groove walls on both sides of the slide groove 32a clamp the protrusion 111. When the back cover 3 is fully pushed into place, the protrusion 111 makes a limiting contact with the end of the slide groove 32a, at which point the side cover section 32 is constrained within the lateral opening 11a and cannot detach. This structure allows for the positioning and installation of the back cover 3 without the need for additional fasteners.

[0047] The back cover 3 is quickly installed through a sliding fit structure. At the same time, the geometric constraints of the sliding groove 32a and the protrusion 111 form a stable mechanical lock, which enables tool-free quick assembly of the back cover 3 and the base 1, effectively preventing component misalignment caused by improper operation during assembly. The fit structure of the sliding groove 32a and the protrusion 111 can ensure that the back cover 3 maintains a stable connection under vibration environment, avoiding the problem of gap expansion caused by long-term use.

[0048] It is worth noting that the opening edges of the relative bottom openings 11b on the opposite side walls of the rear seat 11 are flat surfaces without slide rails or other structures.

[0049] Please refer to Figure 1 and Figure 4 In one embodiment of the present invention, the terminal group 2 includes two terminal pieces 21, with the ends of the two terminal pieces 21 being offset away from the partition plate 12.

[0050] The terminal piece 21 refers to the metal component used for conductive contact, which can be made of copper alloy material by stamping. Its surface can be tin-plated or silver-plated to enhance conductivity. The misalignment setting means that the two terminal pieces 21 are offset in different directions at the end away from the partition 12, which can be achieved by adjusting the length or bending angle of the terminal piece 21.

[0051] Specifically, after the terminal piece 21 is assembled onto the front protruding wall 13, its misaligned ends are exposed within the slot 13a. When the busbar is inserted into the slot 13a, the misaligned ends of the two terminal pieces 21 contact the two sides of the busbar respectively, forming a multi-point conductive path. The misaligned design disperses the contact area between the terminal piece 21 and the busbar, avoiding stress concentration. After the back cover 3 is fixed by the snap 311, the misaligned ends of the terminal piece 21 are confined within the slot 13a, ensuring contact stability.

[0052] By staggering the terminals, the two terminal pieces 21 independently contact different positions of the busbar, maintaining a stable electrical connection even when there are space constraints or cable turning requirements inside the cabinet. This solves the problems of low contact reliability and inability to adapt to multi-directional cable output caused by terminal alignment in existing connectors.

[0053] Please refer to Figure 1 and Figure 4 In one embodiment of the present invention, the end of the terminal piece 21 away from the partition plate 12 is bent toward the slot 13a to form a bent portion 211, and the bent portion 211 forms a protrusion 2111 toward the slot 13a.

[0054] The bent portion 211 refers to the bent structure formed by plastic deformation at the end of the terminal piece 21. Specifically, it can be achieved by bending the metal sheet using a stamping process. By changing the extension direction of the end of the terminal piece 21, it can form multi-angle contact with the busbar. The protrusion 2111 refers to the local bulge formed on the surface of the bent portion 211. Specifically, it can be achieved by processing hemispherical or trapezoidal protrusions on the surface of the bent portion 211 using an in-mold forming process. By increasing the contact pressure, the contact stability between the terminal piece 21 and the busbar is improved.

[0055] Specifically, when the bus is inserted into the slot 13a, the bending angle of the bend 211 guides the bus to slide in along a predetermined path, and the protrusion 2111 makes elastic contact with the bus surface. The bending shape of the bend 211 can compensate for the positional deviation when the bus is inserted, while the protrusion 2111 undergoes micro-deformation during the contact process, forming a multi-point contact mode. The contact area between the terminal piece 21 and the bus changes from the traditional single-plane contact to a composite contact structure composed of the bend 211 and the protrusion 2111.

[0056] The combination of the bending portion 211 and the protrusion 2111 creates a three-dimensional spatial distribution of the contact area, automatically adjusting the contact angle during bus insertion to ensure a stable conductive path is established under different assembly conditions. This effectively solves the problem of excessive temperature rise caused by insufficient contact area in traditional connectors. By expanding the contact range with the bending portion 211 and enhancing the contact pressure with the protrusion 2111, high current carrying capacity is achieved within a limited space. At the same time, it can also adapt to the insertion requirements of busbars of different thicknesses and maintain a reliable electrical connection under vibration conditions.

[0057] Please refer to Figure 5 This utility model also proposes a connector assembly 2000, which includes at least one secondary connector 4, at least one wire harness 5, and a high-current connector 1000. The specific structure of the high-current connector 1000 is as described in the above embodiments. Since this connector assembly 2000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The wire harness 5 is assembled and connected to the two end sub-groups 2, and the secondary connector 4 is assembled and connected to the end of the wire harness 5 away from the high-current connector 1000.

[0058] Secondary connector 4 refers to an auxiliary connection component used for extended connections or transitions. Specifically, it can be implemented using a combination of metal terminals with a plug-in structure and an insulating shell. It forms an electrical path with high-current connector 1000 via wire harness 5, facilitating the distribution of multiple signals or currents within a limited space. Wire harness 5 refers to a cable assembly composed of multiple conductors or conductive bodies. Specifically, it can be implemented using stranded copper wire with an outer insulating layer. Its two ends are connected to terminal group 2 and secondary connector 4 via crimping or welding to form a detachable connection, allowing the wire output direction to be flexibly adjusted according to actual needs. Assembled connection refers to a detachable fixing method achieved through plugging, snap-fit ​​311, or threaded engagement, facilitating quick positioning and fixing of wire harness 5 with terminal group 2 and secondary connector 4 during installation.

[0059] Please refer to Figure 5 In one embodiment of the present invention, the connector assembly 2000 includes two wire harnesses 5, each wire harness 5 being assembled to a terminal group 2, and both wire harnesses 5 being assembled to a secondary connector 4; wherein the conductor polarities of the two wire harnesses 5 are opposite.

[0060] Among them, the opposite polarity of the conductors means that the current direction of the conductors in the two wire harnesses 5 is opposite. Specifically, this can be achieved by adjusting the connection direction of the wire harness 5 and the terminal during assembly, in order to avoid the risk of short circuit caused by current superposition and to maintain circuit balance.

[0061] Specifically, the two wire harnesses 5 are connected to the two terminal groups 2 respectively. The terminal groups 2 are fixed to the front protruding walls 13 on both sides of the base 1 and exposed through slots 13a, allowing the wire harnesses 5 to be led out from both sides of the base 1. The ends of the wire harnesses 5 away from the high-current connector 1000 are connected to the secondary connector 4, which serves as a centralized interface to adapt to different external devices. The conductor polarities of the two wire harnesses 5 are set to opposite directions during the connection process, for example, by reverse crimping the terminals or adjusting the wiring path of the wire harnesses 5, thereby forming complementary current loops inside the secondary connector 4.

[0062] By setting up two independent wire harnesses 5 and connecting them to the same primary connector 4, the wire harnesses 5 can be led out from the left or right side of the base 1 according to actual needs. At the same time, the conductor layout with opposite polarities effectively reduces electromagnetic interference and improves the stability of current transmission.

[0063] Please refer to Figure 5 In one embodiment of the present invention, the connector assembly 2000 further includes two heat shrink tubing 6, each heat shrink tubing 6 being sleeved on a wire bundle 5, and the two heat shrink tubing 6 being stacked in layers within the open lateral opening 11a.

[0064] Among them, the heat-shrink tubing 6 refers to an insulating protective tube with heat-shrinkable properties. Specifically, it can be made of polyolefin material. By heating, it shrinks and tightly wraps the conductor of the wire harness 5, thus providing insulation and protection. The stacked installation refers to two heat-shrink tubing 6 being stacked one on top of the other within the lateral opening 11a. Specifically, different wire exit layouts can be achieved by adjusting the order in which the tubing is inserted.

[0065] Specifically, after the two wire harnesses 5 are fitted with heat-shrink tubing 6, their conductor ends are connected to the terminal group 2, and the other end extends to the side opening 11a. Since the side opening 11a is not closed by the back cover 3, the operator can pass the two wire harnesses 5 fitted with heat-shrink tubing 6 out from the same side opening 11a and arrange them in a stacked manner. One wire harness 5 can be placed on the upper layer and the other on the lower layer, thus adapting to the space constraints inside the cabinet.

[0066] By opening the lateral opening 11a and using the sleeve layering method, the wire harness 5 can freely choose the upper and lower layer positions within the same opening, thereby flexibly adjusting the left and right outgoing directions. Operators can select the stacking order of the wire harness 5 according to the actual scenario, so that the cable avoids interference from surrounding devices and shortens the wiring path. The insulation protection of the heat shrink tubing 6 combined with the open structure of the lateral opening 11a achieves dynamic adaptation of the outgoing direction while ensuring electrical safety.

[0067] Please refer to Figure 5 In one embodiment of the present invention, the connector assembly 2000 includes two secondary connectors 4, and each wire harness 5 is assembled and connected to the primary connector 4.

[0068] Specifically, one end of the wiring harness 5 is electrically connected to the high-current connector 1000 via the terminal group 2, and the other end is fixed to two secondary connectors 4 via an assembly connection. By setting two secondary connectors 4, the wiring harness 5 can selectively extend in different directions according to the layout requirements of the actual cabinet or module.

[0069] By independently setting two secondary connectors 4, the wiring harness 5 can select different wiring paths according to the actual scenario, avoiding wiring conflicts caused by space limitations.

[0070] 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.
