Description

Technical Field

[0001] The present invention relates to the technical field of new energy electric vehicles, and specifically, to a screw-locking splint type bent aluminum busbar connector. Background Art

[0002] Currently, the high-voltage connectors on new energy electric vehicles have various structural shapes, and most of the existing high-current connectors use crimping copper wires, welding copper wires, or directly screwing copper busbars to conduct high current transmission. However, the raw material costs of copper wires and copper busbars are high and the weight is large, which does not meet the requirements of low cost and lightweight; and most of the existing high-current connectors use a front-panel screw-locking structure, and due to factors such as its own weight, the thickness of the installation area needs to be required to avoid deformation at the installation position, so as to meet the normal airtight function. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a screw-locking splint type bent aluminum busbar connector, which is mainly used for connection ports such as high-current automotive power units, battery power supplies, and charging systems. This connector is suitable for aluminum busbar cables with a diameter of 50 mm 2 ~300 mm 2 and has a wide range of suitable wire diameters.

[0004] The present invention solves the above problems through the following technical solutions:

[0005] A screw-locking splint type bent aluminum busbar connector, comprising:

[0006] A plug housing with a 90° corner design, the upper part of the plug housing is detachably and sealed with a plug cover, the left part is sealed with an aluminum busbar cable inserted, the lower part is sealed with a socket housing inserted, and a splint is provided at the lower end of the socket housing. A customer installation interface can be hermetically crimped between the socket housing and the splint through a screw assembly;

The aluminum column end is locked with the aluminum busbar cable through a screw assembly, and the copper column end is locked with the client copper busbar through a screw assembly to form power conduction of the aluminum busbar cable - power transfer terminal - client copper busbar.

[0008] As a further improvement, the plug cover is fixed to the opening at the upper part of the plug housing through a pin rod and can rotate to close the opening.

[0009] As a further improvement, the plug cover is also locked on a plastic-sealed nut fixed in the plug housing through a screw assembly to form a cooperative fixation with the socket housing.

[0010] As a further improvement, the latch rod is provided with a torsion spring cooperating with the plug cover, so that when the plug cover is closed, the torsion spring interferes with the plug housing and is compressed to form a force to open the plug cover; and / or

[0011] A fixed hook is provided at the front of the plug cover, and an unlockable hook matching the fixed hook is provided at the front of the plug housing to achieve pre-fixation of the plug cover, making it easier for subsequent screw assemblies to lock the plug cover and the plug housing.

[0012] As a further improvement, a reverse hook is provided in the splint, and a matching boss is provided at a corresponding position in the socket shell. When installing the socket assembly and the splint assembly, the reverse hook of the splint cooperates with the boss of the socket shell for pre-fixation, which facilitates the subsequent screw assembly to lock the socket assembly and the splint assembly.

[0013] As a further improvement, a symmetrical flat position is processed on the power transfer terminal, and a spring buckle is provided on the wall of the power through hole on the clamp. When the power transfer terminal is installed on the clamp, the spring buckle on the clamp catches the flat position on the power transfer terminal to stop rotation and complete primary fixation; after the clamp assembly and the socket assembly are installed and fixed, the spring buckle on the clamp is held by the socket shell and cannot bounce open, forming a secondary locking structure of the power terminal.

[0014] As a further improvement, the connector has five waterproof seals.

[0015] As a further improvement, the five waterproof seals include:

[0016] A plug sealing ring is arranged in the lower part of the plug housing. After the plug assembly and the socket assembly are plugged and locked, the plug sealing ring is clamped by the outer wall of the plug housing and the inner wall of the socket housing, forming a first waterproof seal for the plug assembly and the socket assembly.

[0017] The left end of the plug housing, i.e. the tail end, is loaded with the plug sealing body and the plug tail cover. The plug tail cover and the plug housing are buckled to prevent the plug sealing body from deforming and retreating. The plug sealing body is clamped and fixed in the plug tail cover to form a second waterproof seal at the tail of the plug assembly.

[0018] A first sealing groove is provided on the bottom surface of the plug cover, and a sealing ring of the cover is assembled and fixed in the first sealing groove of the plug cover; after the plug cover is locked and fixed, the plug housing and the plug cover clamp the sealing ring of the cover to form a third waterproof seal from the plug cover to the plug housing;

[0019] A second downward sealing groove is provided at the lower part of the socket housing, and the socket sealing ring is assembled and fixed in the second sealing groove of the socket housing. After the socket housing is locked and fixed, the socket sealing ring is clamped in the customer installation interface to form a fourth waterproof seal from the socket housing to the customer installation interface;

[0020] The splint is provided with an upward third sealing groove, in which a splint sealing ring is assembled and fixed. After the splint is locked, it cooperates with the customer installation interface to clamp the splint sealing ring therein, forming a fifth waterproof seal from the splint to the customer installation interface.

[0021] As a further improvement thereof, the plug sealing ring is provided with 2 to 6 inner and outer lips.

[0022] As a further improvement thereof, a wire sealing body baffle is further provided at the left end of the plug housing, and the wire sealing body baffle acts on the support rib position formed by the escape of the material at the tail of the plug housing; and / or

[0023] After the plug end cap is fastened in place, a reinforcing rib support is provided on the wire protection structure part of the plug end cap.

[0024] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0025] (1) In the present invention, the plug assembly, the socket assembly, and the splint assembly are all fixed by inserting and locking with screws, making the installation more stable and the electrical conductivity more excellent. The 90° corner design saves the installation space in the vehicle, makes the circuit layout more reasonable, reduces circuit interference and energy loss. In addition, the connector uses high-quality plastic materials, making it have good insulation performance and corrosion resistance, and can effectively ensure the safe operation of the circuit. For the sealing design, the connector is designed in the form of locking and clamping the socket assembly and the splint assembly, which can effectively reduce the deformation of the installation area surface, so as to meet the sealing requirements under different wall thicknesses. At the same time, its power transfer terminal uses a copper-aluminum composite alloy terminal, which can achieve 85% of the conductivity of a copper terminal with the same cross-sectional area, and can greatly reduce the electrochemical corrosion during the transfer of copper and aluminum metals.

[0026] (2) The connector structure of the present invention is designed compactly, smaller in volume and lighter in weight than connectors with the same current-carrying capacity, which is convenient for carrying and installation, reduces the installation operation difficulty of personnel, and greatly improves the work efficiency.

[0053] Specifically, a screw-locking splint type bent aluminum bar connector has a specific structure as follows:

[0054] I. Five waterproof and sealing designs:

[0055] 1.1) There is a plug sealing ring 8 inside the lower part of the plug housing 7. The plug sealing ring 8 can be designed with 2 to 6 inner and outer lips. After the plug assembly and the socket assembly are inserted and locked together, the outer wall of the plug housing 7 and the inner wall of the socket housing 14 clamp the plug sealing ring 8 to form the first waterproof seal for the insertion of the plug assembly and the socket assembly. Among them, the form of the plug sealing ring 8 can be designed as a radial seal form or an end face seal form with 2 to 6 lips according to the specific use scenario;

[0056] 1.2) At the left end (i.e., the tail) of the plug housing 7, a wire sealing body baffle 10, a plug wire sealing body 11, and a plug tail cover 12 are sequentially installed. The wire sealing body baffle 10 acts on the support rib position formed by the escape of materials at the tail of the plug housing 7. At the same time, the plug tail cover 12 is engaged with the plug housing 7 to prevent the plug wire sealing body from deforming and retreating. The plug wire sealing body is clamped and fixed between the plug tail cover 12 and the wire sealing body baffle 10 to form the second waterproof seal at the tail of the plug assembly. After the plug tail cover 12 is engaged in place, there is a reinforcing rib support in the wire protection structure part of the plug tail cover 12 to prevent the aluminum row cable from bending and deflecting during the installation process, which affects the sealing effect, and at the same time enhances the overall structural strength of the tail of the plug housing 7.

[0057] 1.3) The bottom surface of the plug blank cover 1 is provided with a first sealing groove, and several convex ribs are provided in the first sealing groove. The blank cover sealing ring 2 is assembled and fixed in the first sealing groove of the plug blank cover 1. After the plug blank cover 1 is locked and fixed, the plug housing 7 and the plug blank cover 1 clamp the blank cover sealing ring 2 to form the third waterproof seal from the plug blank cover 1 to the plug housing 7. Among them, the form of the blank cover sealing ring 2 can be designed as a radial seal form or an end face seal form with 2 to 6 lips according to the specific use scenario.

[0058] 1.4) The lower part of the socket housing 14 is provided with a downward second sealing groove, and several convex ribs are provided inside the second sealing groove. The socket sealing ring 16 is assembled and fixed in the second sealing groove of the socket housing 14. After the socket housing 14 is locked and fixed, it cooperates with the customer installation interface to clamp the socket sealing ring 16 therein, forming the fourth waterproof seal from the socket housing 14 to the customer installation interface.

[0059] 1.5) The clamping plate 20 is provided with an upward third sealing groove, and the clamping plate sealing ring 18 is assembled and fixed therein. After the clamping plate 20 is locked, it cooperates with the customer installation interface to clamp the clamping plate sealing ring 18 therein, forming the fifth waterproof seal from the clamping plate 20 to the customer installation interface.

[0060] II. Power transfer design:

[0061] The power transfer terminal 17 adopts a copper-aluminum composite alloy terminal. Threaded holes are axially arranged at both ends of the power transfer terminal. The aluminum column end is locked with the aluminum bus cable 13 through the screw assembly 6, and the copper column end is locked with the client copper bus through the screw assembly 6, forming power conduction of the aluminum bus cable-power transfer terminal-client copper bus.

[0062] 3. Structural design:

[0063] 3.1) The plug cover 1 is fixed to the opening at the top of the plug housing 7 by the latch rod 4, and can rotate to close the opening; it is also locked on the plastic nut 5 by the screw assembly 6 to form a fit and fixation with the plug housing 7. A torsion spring 3 that cooperates with the plug cover 1 is provided on the latch rod 4, a fixed hook is provided at the front of the plug cover 1, and an unlockable hook is provided at the front of the plug housing 7. When the plug cover 1 is closed, the torsion spring 3 will interfere with the plug housing 7 and compress to form a force to open the plug cover 1, and the plug cover 1 cooperates with the hook of the plug housing 7 to pre-fix the plug cover 1, which is convenient for the subsequent locking of the screw assembly 6; to open the plug cover 1, it is necessary to remove the screw assembly 6 and unlock the hook on the plug housing 7, and the plug cover 1 will automatically open due to the force of the torsion spring 3, refer to the attached Figure 1 .

[0064] 3.2) A reverse hook is provided in the clamping plate 20, and a matching boss is provided in the corresponding position in the socket housing 14. When the socket assembly and the clamping plate assembly are installed, the reverse hook of the clamping plate 20 is pre-fixed with the boss of the socket housing 14 to facilitate the subsequent locking of the screw assembly. Figure 3 .

[0065] 3.3) A symmetrical flat position is machined on the power transfer terminal 17, and a snap is provided on the wall of the power through hole on the clamping plate 20. When the power transfer terminal 17 is installed on the clamping plate 20, the snap on the clamping plate 20 clamps the flat position on the power transfer terminal 17, completing the rotation prevention and primary fixation. After the clamping plate assembly and the socket assembly are installed and fixed, the snap on the clamping plate 20 is held by the socket housing 14 and cannot be opened, forming a secondary locking structure of the power terminal, refer to the attached Figure 1 .

[0066] Preferably, in this embodiment, there are two aluminum bus cables 13 , which are staggered up and down.

[0067] The screw-locking clamp-type bent aluminum bar connector of the present invention has the following effects:

[0068] (1) The power transfer terminal is made of copper-aluminum composite alloy, that is, the copper column and the aluminum column are welded together by hot rolling or explosive composite method. By connecting the aluminum column end of the power transfer terminal to the aluminum bus cable, and the copper column end to the copper bus, direct contact between the copper terminal and the aluminum terminal during power transmission is avoided, effectively reducing the electrochemical corrosion between the copper and aluminum adapters, and ensuring the stability and safety of current transmission.

[0069] (2) The socket and splint are combined for sealing. By clamping the customer installation interface between the socket and the splint to position and shape it, it effectively avoids the problem of poor airtightness caused by deformation during installation due to the relatively thin installation surface in traditional socket sealing, enabling it to adapt to thinner installation surfaces, greatly improving the sealing stability of the connector when adapting to thinner installation surfaces, while reducing the weight of the box body, lowering the manufacturing cost of the box body, and making the overall vehicle design lighter.

[0070] (3) The plug assembly with a 90° corner design makes the overall design of the connector more compact, with overall dimensions smaller than those of similar connectors, effectively reducing the occupied space of the connector in the vehicle. At the same time, it enables the cable to be closer to the vehicle body or components, reducing the cable length and simplifying the wiring, improving the overall layout efficiency of the vehicle.

[0071] (4) Selecting high-quality plastic materials reduces the weight of the connector, lowers the cost of the connector, and also improves its corrosion resistance and insulation performance, ensuring the normal operation of the vehicle in harsh environments.

[0072] (5) The plug assembly and the socket assembly are designed with a foolproof structure when plugged together, which can effectively avoid incorrect connection during installation and improve the accuracy and safety of connector assembly.

[0073] (6) The connector can be adapted to aluminum bar cables with a cross-sectional area of 50 - 300 mm². Structurally, it has a wide adaptability to wire diameters and can meet the wire diameter requirements of most large-current connectors for the whole vehicle.

[0074] (7) Both terminal connection and connector installation use screw locking connections. By providing a firm connection through mechanical fastening, it can withstand higher vibrations, impacts, and temperature changes, ensuring long-term stability and adapting to harsh in-vehicle environments.

[0075] (8) The connector has good sealing performance, can effectively prevent the intrusion of moisture and dust, can meet the performance requirements of IP68 level, and further improves the reliability and service life of the connector.

[0076] (9) The socket assembly and the splint assembly are designed with a pre-fixed structure for installation, and the plug cover is designed with a pre-fixed and automatic opening structure, reducing the tooling positioning and manual operations, and making the connector installation operation more convenient.

[0077] (10) The power transfer terminals are arranged in a staggered manner, eliminating the bending step of the aluminum bar, reducing the manufacturing cost, enabling the connector to have more terminal contact area under the same width, reducing the transfer resistance, and adapting to a larger current-carrying design.

[0078] Although the present invention has been described herein with reference to illustrative embodiments thereof, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited by the above embodiments. It should be understood that those skilled in the art can design many other modifications and embodiments, which will fall within the scope and spirit of the principles disclosed in this application.
