Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector. Background Technology

[0002] Electrical connectors are typically used at the power output end. They are interface components that transmit electrical energy from power modules (such as uninterruptible power supplies, battery packs, and distribution cabinets) to downstream devices. They are commonly used to distribute main power to various electrical devices.

[0003] When existing electrical connectors are connected to other electrical components, the interfaces of different components vary. Some components can be directly connected, while others require flipping the connector to complete the connection. However, in confined spaces, the connector may be blocked from flipping and inserting, thus preventing connection to some electrical components. This limits the application scenarios of electrical connectors and results in insufficient adaptability. Utility Model Content

Each spring clip is rotatably connected to opposite side walls of the U-shaped groove via a pivot. Partial structures of both spring clips are exposed on the second surface of the base.

[0023] When electrical connectors are used as power output interface components, the different interface orientations of electrical components of different specifications mean that in space-constrained installation environments, connectors often cannot be flipped due to physical obstructions from adjacent structures, resulting in incomplete connections with some electrical components. This problem essentially stems from the connector's structural design lacking directional adaptability, making it difficult to accommodate multi-directional interface requirements in fixed installation positions, thus limiting the application range of electrical connectors.

[0024] For example, in high-density server rack deployments in data centers, electrical connectors need to connect to uninterruptible power supply (UPS) modules and power distribution units. The internal space of the rack is limited, and it contains dense cable bundles and heat dissipation components. Once the electrical connector is fixed in place, its rotation path is blocked by adjacent devices. When connecting to a power distribution unit with a reverse interface, the electrical connector cannot rotate 180 degrees, making it impossible to plug in, thus preventing the power transmission link from being established and affecting the normal operation of the entire power distribution system.

[0025] To solve the above problems, this utility model proposes an electrical connector 1000. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 This is a schematic diagram of an embodiment of the electrical connector 1000 provided by this utility model.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This utility model proposes an electrical connector 1000, including a housing 1 and a terminal assembly. The housing 1 includes a base 11 and a plurality of protrusions 12. The base 11 has opposing first surfaces 11a and second surfaces 11b. Each protrusion 12 protrudes from the first surface 11a of the base 11 at intervals. The housing 1 has a plurality of mounting holes 1a, each mounting hole 1a penetrating a protrusion 12 and the base 11. The terminal assembly includes a plug 21 and a plurality of electrical terminals 22. Each electrical terminal 22 includes a plug section 221 and a bent section 222 connected to each other. The plug 21 and each plug section 221 are respectively disposed in each mounting hole 1a in a one-to-one correspondence, wherein the plug 21 is located in one of the two outer mounting holes 1a. Each bent section 222 is located outside the corresponding mounting hole 1a and is bent toward the protrusion 12 where the plug 21 is located.

[0027] This application provides an electrical connector 1000, the housing 1 of which includes a base 11 and a plurality of protrusions 12. The base 11 has opposing first surfaces 11a and second surfaces 11b. In practical applications, the protrusions 12 protruding from the first surface 11a of the base 11 at intervals means that the protrusions 12 are distributed at predetermined positions on the first surface 11a of the base 11. This can be achieved by integrally forming the protrusions 12 during the manufacturing of the base 11 through an injection molding process, or by installing independent protrusion structures on the surface of the base 11 through machining, such as directly forming the protrusions 12 in a mold, or drilling holes in the base 11 and fixing the protrusions. The housing 1 has a plurality of mounting holes 1a, each mounting hole 1a penetrating a protrusion 12 and the base 11. Specifically, the mounting holes 1a can be formed by machining the hole positions using drilling or stamping processes, such as using a CNC machine tool for hole machining, or embedding a core structure during the injection molding process. The terminal assembly includes a plug 21 and multiple electrical terminals 22, each electrical terminal 22 including a plug section 221 and a bent section 222 connected to each other. The plug 21 being located in one of the two outer mounting holes 1a means that the plug 21 is positioned within the mounting hole 1a at the edge, which can be implemented by selecting the outer hole for mounting the plug 21 during assembly. Each bent section 222 is bent towards the protrusion 12 where the plug 21 is located, meaning the bending direction of the bent section 222 points towards the protrusion 12 where the plug 21 is located, which can be implemented by forming the bending angle using a bending die during terminal manufacturing.

[0028] The outer casing 1 has multiple mounting holes 1a, while the number of electrical terminals 22 is one less than the number of mounting holes 1a. Each electrical terminal 22 is installed in one mounting hole 1a, and the remaining mounting hole 1a is used to install a plug 21. For example, when the number of electrical terminals 22 is four, the number of protrusions 12 and mounting holes 1a is five each. One of the two outer mounting holes 1a is used to install a plug 21, and the other four are used to install electrical terminals 22. In this example, the plug 21 is insulating and is used to block the mounting hole 1a, but it can be replaced with a conductive material if needed.

[0029] When traditional electrical connectors need to be flipped to connect with other electrical components, but cannot be flipped due to limitations in the application environment, the electrical connector 1000 proposed in this invention can achieve the same effect as flipping a traditional electrical connector by changing the direction in which each electrical terminal 22 is inserted into the mounting hole 1a, so that it is inserted from the other end of the mounting hole 1a. After changing the insertion direction, since the plug 21 does not expose the structure of the mounting hole 1a where it is located, it will not cause spatial interference to the bent section 222 of each electrical terminal 22. In summary, the electrical connector 1000 will not be unable to connect with other electrical components due to space limitations, and can be compatible with electrical components with different connection directions, thus improving its adaptability.

[0030] Please refer to Figure 1 and Figure 3 In one embodiment of the present invention, a cable groove 222a is provided at one end of each bent segment 222 away from the corresponding plug segment 221, and the axial direction of each cable groove 222a is perpendicular to the axial direction of the corresponding mounting hole 1a; each cable groove 222a is configured to accommodate the cable for electrical connection; the axis of each cable groove 222a is aligned with the side of the corresponding protrusion 12 near the plug 21.

[0031] Alignment of the axis of each cable groove 222a with the side of the corresponding protrusion 12 closest to the plug 21 means that the center line of the cable groove 222a coincides with the edge of the protrusion 12. This can be achieved by controlling the bending process parameters to ensure that the two are aligned.

[0032] After changing the insertion direction, the axis of the cable groove 222a remains aligned with the edge of the corresponding protrusion 12, just as before the insertion direction was changed. This ensures that the wiring position of the electrical connector 1000 does not change significantly after the insertion direction is changed, making it convenient for users.

[0033] Please refer to Figure 4 In one embodiment of the present invention, the plug segment 221 is provided with a receiving groove 221a, the opening of the receiving groove 221a is located at the end of the plug segment 221 away from the bending segment 222; the electrical terminal 22 also includes an insulating post 223, one end of the insulating post 223 is provided on the bottom wall of the receiving groove 221a, and the other end extends toward the opening of the receiving groove 221a and is exposed in the opening of the mounting hole 1a.

[0034] The receiving groove 221a refers to a groove structure opened on the plug section 221 to accommodate insulating material. It can be a cylindrical groove or rectangular groove formed by stamping or milling on the surface of the metal terminal. Its purpose is to provide installation space for the insulating post 223 and guide the insertion path of external components. The slot position refers to the location of the opening end of the receiving groove 221a. It can be set at the end of the plug section 221 away from the bending section 222. For example, by designing the geometry of the terminal so that the slot faces the insertion direction of the external component, its purpose is to effectively block the risk of direct contact between the metal electrical terminal 22 and the user's fingers during the plugging operation. The insulating post 223 refers to a columnar component made of insulating material. It can be made of ceramic, plastic or rubber material and formed by injection molding or pressing process.

[0035] Specifically, the plug section 221 has a receiving groove 221a with the groove opening located at the end away from the bending section 222. One end of the insulating post 223 is fixed to the bottom wall of the receiving groove 221a as a support base point to maintain long-term stability, and the other end extends to the groove opening of the receiving groove 221a and is exposed in the mounting hole 1a to prevent the user's fingers from being inserted into the receiving groove 221a and directly contacting the metal electrical terminal 22.

[0036] As a specific implementation method, the solution of this application is implemented as follows: the receiving groove 221a of the plug section 221 is specifically a cylindrical groove formed on the copper alloy terminal, with the groove opening facing the insertion direction of the external component; the insulating post 223 is specifically a cylinder made of polytetrafluoroethylene material, one end of which is snapped and fixed to the bottom wall of the receiving groove 221a, and the other end extends to the groove opening and slightly protrudes from the opening of the mounting hole 1a. Through the above solution, this application effectively prevents direct contact between the metal electrical terminal 22 and the user, significantly improving the safety of the electrical connector 1000.

[0037] Please refer to Figure 4 In one embodiment of the present invention, the electrical terminal 22 further includes an insulating ring 224 and an annular terminal piece 225. The insulating ring 224 is disposed around the opening of the receiving groove 221a, and the annular terminal piece 225 is disposed on the peripheral wall of the receiving groove 221a.

[0038] Among them, the insulating ring 224 refers to the insulating component set around the opening of the receiving groove 221a. It can be made of silicone or polytetrafluoroethylene material in a ring structure. Its purpose is to block the direct contact between the user and the electrical terminal 22 during the insertion process. The annular terminal piece 225 refers to the conductive component set on the periphery of the receiving groove 221a. It can be made of copper alloy or stainless steel material in a ring-shaped sheet structure. Its purpose is to ensure uniform electrical contact with external components, reduce contact resistance fluctuations and enhance the stability of current conduction.

[0039] Specifically, the solution of this application forms a continuous insulating barrier by placing an insulating ring 224 around the periphery of the groove opening of the receiving groove 221a, preventing accidental contact by the user during insertion. Simultaneously, an annular terminal piece 225 is disposed on the groove periphery of the receiving groove 221a, utilizing the geometric continuity of the annular structure to create a stable and uniform electrical contact interface between the external component and the electrical terminal 22. This design not only strengthens the insulation protection of the groove opening area but also optimizes the current conduction path, thereby improving the overall safety and reliability of the electrical connection.

[0040] Please refer to Figure 4 In one embodiment of the present invention, an annular groove is formed on the inner peripheral wall of the insulating ring 224, and a convex ring is formed on the outer peripheral wall of the end of the insertion section 221 away from the bending section 222, and the convex ring is engaged in the annular groove.

[0041] In practical applications, the annular groove refers to the annular recessed structure on the inner circumferential wall of the insulating ring 224. It can be formed by stamping or injection molding, and its purpose is to provide precise axial constraint space to prevent the insulating ring 224 from sliding axially along the insertion section 221 when subjected to external force. Specifically, the convex ring refers to the annular protrusion structure on the outer circumferential wall of the insertion section 221. It can be formed by machining or casting, and its purpose is to cooperate with the annular groove to produce a radial locking effect and resist the circumferential rotation of the insulating ring 224. Among them, the snap-fit ​​refers to the interference fit connection mechanism between the convex ring and the annular groove. It can be understood as a tool-less assembly method that utilizes the elastic deformation of the material. Its purpose is to simplify the fixing process, disperse local stress, and reduce wear caused by repeated insertion and removal.

[0042] Specifically, the solution of this application forms a dual fixing mechanism through the snap-fit ​​of the annular groove and the convex ring: the axial concave structure of the annular groove applies precise axial limiting to the insulating ring 224, effectively suppressing axial displacement caused by external forces during the insertion process; at the same time, the convex ring is located at the end of the insertion section 221 away from the bending section 222, and this position directly bears the insertion force of the external component, so that the insertion impact force is converted into radial locking force, thereby firmly constraining the circumferential rotation of the insulating ring 224; the snap-fit ​​utilizes the elastic deformation of the material to achieve rapid assembly, and the interference fit disperses the local stress during the insertion and extraction process, avoiding the extra operating space required by traditional bonding or threaded fixing, and ensuring the long-term stable operation of the insulating ring 224.

[0043] As a specific implementation method, the solution of this application is implemented as follows: the insulating ring 224 is made of polyamide material through injection molding, and its inner peripheral wall forms an annular groove; the plug section 221 is made of copper alloy material through stamping, and its outer peripheral wall forms a convex ring; during assembly, the convex ring is engaged with the annular groove under elastic deformation, thereby achieving reliable fixation between the insulating ring 224 and the plug section 221. Through the above solution, this application effectively prevents the axial displacement and circumferential rotation of the insulating ring 224 when external components are plugged in or when the equipment vibrates, avoiding insulation failure, contact point misalignment and short circuit risks, and significantly improving the connection reliability and operational safety of the electrical connector 1000 in space-constrained scenarios.

[0044] Please refer to Figure 1 , Figure 2 as well as Figure 3 In one embodiment of the present invention, the electrical connector 1000 further includes a fixing component, which includes two spring clips 31. U-shaped grooves are formed on the opposite side walls of the base 11. Each spring clip 31 is rotatably connected to the opposite side walls of the U-shaped groove via a rotating shaft. Part of the structure of the two spring clips 31 is exposed on the second surface 11b of the base 11. The two spring clips 31 are rotatably engaged to clamp the external component to the base 11 when the external component is inserted into the electrical connector 1000.

[0045] Specifically, the U-shaped groove refers to the U-shaped groove structure formed on the side wall of the base 11. It can be integrally formed on the base 11 by metal stamping or plastic injection molding. Its purpose is to provide rotation guidance and support for the spring buckle 31 and ensure the stability of the movement trajectory of the spring buckle 31. The spring buckle 31 can be understood as an elastic clamping component. It can be made of spring steel or elastic plastic material. Its purpose is to clamp and fix the external component through elastic deformation and provide the necessary clamping force. In practical applications, rotational engagement specifically refers to the interaction between the two spring buckles 31 during rotation to clamp the external component.

[0046] Specifically, the fixing component accommodates the rotating shaft through the U-shaped grooves on both sides of the base 11, allowing the spring clips 31 to rotate around the rotating shaft; when the external component is inserted into the electrical connector 1000, the two spring clips 31 rotate inward and cooperate with each other, thereby clamping the external component.

[0047] Please refer to Figure 3 In one embodiment of the present invention, the fixing component further includes two elastic members 32; one end of each snap-fit ​​31 is used to clamp an external component, and the other end is connected to the bottom wall of the U-shaped groove through an elastic member 32; the elastic member 32 is used to push the other end of the snap-fit ​​31 away from the bottom wall of the U-shaped groove.

[0048] In practical applications, the elastic element 32 refers to a component that can store and release energy through elastic deformation. It can be implemented using a helical spring, leaf spring, or elastic rubber material. Its purpose is to provide the driving force required for the spring clip 31 to maintain the clamping force. The clamping end of the spring clip 31 refers to the part designed to contact the surface of the external component and apply clamping force. It can be implemented using a groove or a planar protrusion structure. Its purpose is to ensure that the external component is firmly fixed after insertion. Specifically, the connecting end of the spring clip 31 refers to the part that forms a power transmission relationship with the bottom wall of the U-shaped groove through the elastic element 32. It can be implemented using a hinge shaft or a snap-fit ​​fixed connection method. Its purpose is to effectively convert the thrust of the elastic element 32 into the rotational motion of the spring clip 31.

[0049] Specifically, when an external component is inserted into the electrical connector 1000, the clamping end of the spring clip 31 is squeezed downward by the external force, causing the connecting end of the spring clip 31 to rotate around the axis towards the bottom wall of the U-shaped groove. At this time, the elastic element 32 is compressed and deformed to store elastic potential energy. After the external component is inserted, the elastic element 32 releases the stored energy, and the resulting thrust acts directly on the connecting end of the spring clip 31, pushing the end away from the bottom wall of the U-shaped groove, thereby clamping the external component onto the base 11.

[0050] Through the above solution, this application significantly improves the disassembly efficiency of the electrical connector 1000, enhances the convenience of equipment maintenance, and improves its adaptability to different installation scenarios.

[0051] Please refer to Figure 5 In one embodiment of the present invention, the base 11 has a plurality of through holes 11d, and the terminal assembly also includes a plurality of signal pins 23, each signal pin 23 being inserted into a through hole 11d; each signal pin 23 is electrically connected to each power terminal 22 to monitor whether each power terminal 22 is energized.

[0052] In practical applications, the through hole 11d refers to the through hole structure on the base 11 used to accommodate the signal pin 23. It can be implemented using a circular, elliptical, or irregularly shaped cross-section hole, with the aim of providing installation space by utilizing the existing physical layout of the base 11. The signal pin 23 refers to a conductive monitoring element independent of the power terminal 22. It can be implemented using a slender needle-like structure made of copper alloy, phosphor bronze, or gold-plated metal, with the aim of reflecting the energized state through changes in electrical characteristics. Its shape can be designed as a straight pin or a structure with a flexible contact part. Specifically, the electrical connection refers to the stable electrical path established between the signal pin 23 and the power terminal 22. It can be implemented using flexible contact, welding, or conductive adhesive bonding, with the aim of ensuring that the signal pin 23 can capture the current changes of the power terminal 22 in real time, thereby accurately feeding back the energized state.

[0053] Specifically, the solution of this application forms an electrical connection between the signal pin 23 and the power terminal 22 by opening a through hole 11d on the base 11 and embedding a signal pin 23. When the power terminal 22 is energized, the current is transmitted to the signal pin 23 through the electrical connection path. The external monitoring device can detect the change in the electrical parameters of the signal pin 23 and thus determine whether the energization status is normal. This design makes full use of the structural features of the base 11 and integrates the monitoring function into the terminal assembly without changing the core layout of the original electrical connector 1000, thus achieving accurate monitoring of the energization status of the power terminal 22.

[0054] As a preferred embodiment, the solution of this application is specifically implemented as follows: the signal pin 23 is a cylindrical structure made of gold-plated copper alloy, one end of which is connected to the power terminal 22 through an elastic contact part, and the other end is partially exposed on the surface of the base 11; the size of the through hole 11d matches the signal pin 23 to ensure that the pin is firmly embedded inside the base 11.

[0055] Through the above solution, this application realizes real-time monitoring of the power-on status of the docking electrical terminal 22, which can promptly identify connection abnormalities or open circuit faults, avoiding the risk of equipment damage caused by power transmission interruption, and effectively improving the operational reliability and safety of the electrical connector 1000, especially in power output application scenarios.

[0056] Please refer to Figure 5 In one embodiment of this utility model, each signal pin 23 is exposed on the second surface 11b.

[0057] Among them, the signal pin 23 refers to the conductive element used to monitor the energized state of the power terminal 22. It can be implemented using a needle-like structure made of metal, and its purpose is to provide a contactable detection point to obtain current information.

[0058] Specifically, by setting each signal pin 23 to be exposed on the second surface 11b of the base 11, when the electrical connector 1000 is installed on the device, the second surface 11b is usually exposed to the external operating space, so that the monitoring device can directly contact the signal pin 23 to detect the power-on status without adjusting the position of the electrical connector 1000 or disassembling the housing 1, thereby avoiding the problem of difficulty in flipping due to space constraints and ensuring the feasibility of monitoring operations.

[0059] Through the above solution, the monitoring device can directly access the signal pin 23, simplifying the power-on status monitoring process and effectively improving the practicality and adaptability of the electrical connector 1000 in space-constrained scenarios.

[0060] Since the electrical connector 1000 is used in a server rack where the ambient temperature is high, the housing a connected to the outer shell 1 may expand due to heat, causing the base 11 to deform under pressure.

[0061] Please refer to Figure 5 and Figure 6 In one embodiment of the present invention, a shaped groove 11b1 is provided on the second surface 11b to provide space for the shell a provided on the second surface 11b for thermal expansion and contraction.

[0062] Specifically, the irregular groove 11b1 refers to a groove with an irregular geometric shape, which can be realized by adopting a wave-shaped, star-shaped or irregular polygon shape, etc. The purpose is to provide the shell a with deformation and compression space in multiple directions, thereby effectively relieving the interface mechanical stress caused by thermal expansion and contraction.

[0063] Specifically, the solution of this application directly sets the irregular groove 11b1 on the second surface 11b of the base 11, allowing the shell a to freely expand or contract along the irregular contour of the groove when the temperature fluctuates. Since the second surface 11b is the interface where the shell a is directly attached, the thermal expansion and contraction effect is most significant here. The geometry of the irregular groove 11b1 can distribute the multi-directional deformation requirements, avoid local stress accumulation, and thus maintain the tight fit and structural integrity between the shell a and the base 11. At the same time, opening the irregular groove 11b1 on the base 11 can effectively save materials and reduce production costs.

[0064] Through the above solution, the mechanical stress caused by thermal expansion between the housing a and the base 11 is effectively relieved, ensuring the long-term stability and electrical performance reliability of the electrical connector 1000 in high-temperature environments.

[0065] Please refer to Figure 5 and Figure 6 In one embodiment of the present invention, four irregular grooves 11b1 are provided on the second surface 11b, and the four irregular grooves 11b1 are respectively located at the four corners of the second surface 11b.

[0066] Specifically, the solution of this application forms a symmetrically distributed multi-point stress release mechanism by setting four irregularly shaped grooves 11b1 at the four corners of the second surface 11b. During thermal expansion and contraction, the irregularly shaped grooves 11b1 at the four corners work together to evenly distribute material deformation in four high-stress areas, thereby maintaining the overall balance of the shell a structure and preventing torsional deformation. Through the above solution, this application effectively solves the problem of uneven stress distribution during thermal expansion and contraction, reduces the risk of local deformation or cracking of the shell a pressing the base 11, and improves the structural stability and service life of the electrical connector 1000 in high-temperature environments.

[0067] 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.
