Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a high-current metal bus connector. Background Art

[0002] In order to achieve fast charging speed of the connector, especially the charging port of new energy vehicles or electric vehicles is a connector equipped with a charging device such as a charging gun, which requires a higher current carrying capacity and current stability, so it has higher technical requirements. However, in the prior art, connectors usually use wire connections, especially those that rely on traditional wire connections such as wiring harnesses, which face some limitations. First, wiring harness connectors are usually difficult to achieve stable transmission of high currents. This is because the physical properties of the wiring harness, such as the cross-sectional area of ​​the wire and the material resistance, limit the upper limit of the current that it can safely carry. In addition, the wiring harness may wear out during multiple plug-ins and uses, further affecting its electrical performance. Secondly, the current output stability of the wiring harness connector is also a problem. During the charging process, current fluctuations may cause the efficiency of the battery management system to decrease and may even damage the battery.

[0003] In order to change the status quo, the existing Chinese patent: Convenient high-current metal busbar connector, CN116435819A discloses that in order to solve the above problems, it includes a plug shell, an aluminum busbar assembly, a socket assembly and a plug assembly, wherein a horizontal channel and a vertical channel connected to the horizontal channel are arranged in the plug shell, the aluminum busbar assembly inserted in the vertical channel is connected to the plug assembly arranged in the horizontal channel, and the plug assembly is connected to the socket assembly located at the rear end of the plug shell; ... the socket assembly includes a socket long terminal connected to two aluminum busbars respectively, a socket shell inserted into the plug shell, a socket inner shell inserted into the socket shell, a panel waterproof sealing ring and an installation interface, wherein the socket long terminal is sequentially penetrated by a plug front cover, a socket inner shell and an installation interface, and the surface of the end of the aluminum busbar connected to the socket long terminal is sequentially provided with a nickel plating layer and a silver plating layer. It realizes high current transmission to a certain extent through the connection between the aluminum busbar assembly and the socket long terminal, but there are still some limitations and challenges. For example, the connection between the aluminum busbar and the long terminal of the socket may have a high contact resistance, especially after multiple plugging and unplugging, which will affect the charging efficiency. In addition, the long terminal of the socket is still a wire structure, and there are still some challenges in whether it can safely carry high currents. Secondly, although the thermal conductivity of the aluminum busbar assembly is good, it is lower than that of copper. When high current is transmitted, the aluminum busbar assembly may accumulate heat more easily than the copper busbar and easily overheat in the narrow connector space. Furthermore, the design of some accessories of the long terminal of the socket has problems such as complex structure and high cost. Summary of the invention

[0004] In order to overcome the defects of the prior art and address the problems of high current transmission, stable transmission, etc., the utility model provides a high current metal bus connector that can carry large current and improve electrical contact stability.

[0005] The technical solution of the utility model comprises a socket assembly and a plug assembly, the socket assembly comprises a socket strip and a socket shell, the plug assembly comprises a plug strip and a plug shell, the socket strip is fixedly installed in the socket shell, the plug strip is fixedly installed in the plug shell, the socket strip and the plug strip are both made of metal materials, the socket strip and the plug strip can be fastened and connected by a locking piece, and the socket shell and the plug shell are connected to each other by a fixing device to form a fixation.

[0006] By adopting the above technical solution, a larger current flow area can be provided through the connection of socket strips and plug strips instead of traditional wiring harnesses, thereby increasing the upper limit of current that the connector can safely carry, thereby reducing energy loss during current transmission and improving the efficiency of electrical connection transmission. Compared with the connection of wiring harness wires, the physical properties of metal strips are more conducive to maintaining stable electrical contact and reducing resistance changes caused by poor contact. In addition, the provision of locking parts and fixing devices simplifies the connection process and ensures that the various parts of the connector are closely matched during high current transmission, making the connection between the two strips faster and firmer, and enhancing the stability of the connector connection structure. At the same time, the simple structure reduces the number of accessories, is also conducive to simplifying the internal structure, reducing production costs, and facilitating heat dissipation during high current transmission.

[0007] In a possible design, the positions where the socket row and the plug row are connected to each other form a socket row internal connection end and a plug row connection end respectively. The socket row internal connection end and the plug row connection end are arranged parallel or close to each other and are fastened together by a locking member.

[0008] With the above design, the parallel arrangement can maximize the contact area between the two, improve the current carrying capacity, reduce the current density per unit area, reduce resistance and heat generation, and help achieve uniform current distribution, reduce local overheating problems caused by current concentration, and fasten them in specific positions through locking parts, which can ensure that the connection between the socket and the plug is stable during high current transmission, reducing the risk of poor contact or looseness.

[0009] In a possible design, the fixing device includes lugs, notches and fixing bolts. The lugs can be inserted into the notches and the fixing bolts are screwed from the notches into the lugs to form guiding and fixing. The contact position between the lugs and the notches forms a contact surface with a cross-section similar to the shape of the Chinese character "ji", and the contact surface includes a rectangular opening at the top and inclined surfaces in the shape of the Chinese character "ba" on both sides of the rectangular opening. The fixing devices are respectively located on both sides of the socket assembly and the plug assembly in the length direction, and the opposite surfaces of the two lugs form inclined guide surfaces that incline inward.

[0010] With the above design, the inclined surfaces are used to guide the lugs into the notches, and the rectangular openings determine the final fixing positions of the lugs and the notches. In this way, an accurate guiding function is provided, ensuring that the plug assembly and the socket assembly can be accurately aligned during connection, reducing installation errors. The use of the fixing bolts enhances the fixation between the lugs and the notches, provides a reliable fastening force through the screwing method, improves the mechanical connection strength of the entire fixing device, and ensures the stability of the connector during high-current transmission. In addition, the design of this fixing device has a certain degree of flexibility, can adapt to different installation environments and requirements, and increases the application range of the connector.

[0011] In a possible design, the fixing device includes tapered columns and guide holes, and the tapered columns are inserted into the guide holes to form fixation.

[0012] With the above design, the self-guiding characteristic of the tapered columns enables automatic centering when inserted into the guide holes, reducing the error during alignment. The gradually tapering design of the tapered columns can prevent excessive stress on the connector during fastening, protecting the structural integrity of the connector. At the same time, the structure is relatively simple, simplifying the assembly process and the specific structure. When maintenance or replacement of the connector assembly is required, the disassembly and reinstallation processes are more convenient.

[0013] In a possible design, the plug strip further includes a main body section, and an angle of 90° to 180° is formed between the main body section and the connection end of the plug strip.

[0014] With the above design, the easy-to-bend processing feature of the plug strip is utilized, allowing the plug strip to be bent within a limited space, enhancing the space adaptability and enabling it to adapt to different installation requirements and preferences.

[0015] In a possible design, a bushing is fixedly installed inside the socket housing, and the socket strips are inserted and installed inside the bushing. There are at least two socket strips, and the exposed parts of the socket strips outside the socket housing form external connection ends, and adjacent external connection ends are staggered in opposite directions.

[0016] With the above design, the staggered layout helps to reduce interference between adjacent external terminals, reduces the risk of series short circuit, improves the safety of the connector, and also provides more space for heat dissipation, which helps to dissipate heat, especially under high current working conditions.

[0017] In a possible design, the socket housing is provided with a connection port exposing the inner connection end of the socket row, a protruding boss is installed in the plug housing, the plug row connection end is exposed at the table surface of the boss, and the boss and the connection port are adapted to form a limit.

[0018] The above design provides a precise positioning mechanism to ensure that the connecting end of the plug row can be accurately aligned with the inner connecting end of the socket row, thereby improving the connection stability.

[0019] In one possible design, the boss part has a limiting column, and a notch is provided at the connecting end of the plug row. The limiting column is inserted into the notch to form a limiting fit to limit the plug row; a lining part is also installed in the plug housing, and a flange is provided on the inner wall of the lining part. The boss part is integrally provided with a buckle piece, and the buckle piece is snap-connected with the flange to fix the boss part and the lining part; the lining part is fixed with a support platform, and the support platform is located below the connecting end of the plug row to support the connecting end of the plug row.

[0020] With the above design, the cooperation between the limit column and the notch provides a horizontal limit mechanism, ensuring the accurate alignment of the plug strip and the socket strip when connected, and preventing the plug strip from shifting or tilting; and the support platform of the lining is located below the connection end of the plug strip, which provides support for the connection end of the plug strip while limiting the vertical position of the plug strip, reducing the displacement of the connection end of the plug strip due to vibration or impact, thereby maintaining the reliability of the electrical connection, enhancing the stability of the connection between the plug strip and the socket strip, and preventing unstable current transmission due to improper connection.

[0021] In a possible design, the socket strip and the plug strip are mainly made of the metal material copper.

[0022] The above design uses copper as the main material of the socket strip to reduce resistance and improve the efficiency of current transmission. It also has good thermal conductivity, which helps to quickly disperse the heat generated by current transmission and improve the heat dissipation performance of the connector. In addition, copper material is relatively soft and easy to process into various shapes and sizes, making it suitable for use in connector structures that require bending.

[0023] In a possible design, a locking opening is formed in the socket housing, the locking opening is located at a position corresponding to the locking member, the locking opening is covered with a flip cover, and the flip cover is hingedly installed in the socket housing.

[0040] like Figure 1-3 The high-current metal strip connector shown in 7 includes a socket assembly 1 and a plug assembly 2. The socket assembly 1 includes a socket strip 11 and a socket housing 12. The socket strip 11 is fixedly mounted on the socket housing 12. The plug assembly 2 includes a plug strip 21 and a plug housing 22. The plug strip 21 is fixedly mounted on the plug housing 22. The socket strip 11 and the plug strip 21 are both made of metal materials. The socket strip 11 and the plug strip 21 can be fastened and connected by a locking member 3. The socket housing 12 and the plug housing 22 are connected and fixed to each other by a fixing device 4. When the socket assembly 1 and the plug assembly 2 are connected, the socket strip 11 and the plug strip 21 are fastened by the locking member 3, and the socket housing 12 and the plug housing 22 are fixed by the fixing device 4, so as to ensure the firmness of the connection. By adopting direct metal-to-metal connection between the socket strip 11 and the plug strip 21 to replace the traditional wiring harness, the current flow area is significantly increased, the current density per unit area is effectively reduced, the resistance and heat generation are reduced, the current transmission efficiency and the maximum carrying capacity are improved, and a more efficient and reliable electrical connection solution is provided for the power transmission system. Among them, the locking member 3 can be a bolt and a locking nut, the socket strip 11 has a threaded hole, the bolt is threadedly connected to the socket strip 11, the plug strip 21 has a through hole, and the locking nut is fixed in the plug housing 22 below the through hole. When connecting, tighten the bolt so that it is screwed into the through hole and the locking nut in turn, thereby fixing the socket strip 11 and the plug strip 21.

[0041] like Figure 2-7 As shown, the positions where the socket strip 11 and the plug strip 21 are connected to each other form the socket strip internal connection end 111 and the plug strip connection end 211, respectively. The socket strip internal connection end 111 and the plug strip connection end 211 are actually located at the ends of the socket strip 11 and the plug strip 21, respectively. The socket strip internal connection end 111 and the plug strip connection end 211 are both plate-shaped structures. The socket strip internal connection end 111 and the plug strip connection end 211 are arranged parallel to each other and are fastened and connected by the locking member 3. In particular, the positions where the socket strip internal connection end 111 and the plug strip connection end 211 contact each other are parallel and fit, so as to maximize the contact area as much as possible, and ensure that the current flow cross section meets the high current transmission requirements. In addition, the socket strip internal connection end 111 and the plug strip connection end 211 are fastened by the locking member 3 to ensure close contact, which ensures stable connection under high current transmission and effectively avoids the resistance change and heat concentration problems caused by poor contact.

[0042] like Figure 1 , 3 As shown in FIGS. -5, the fixing device 4 includes lugs 41, notches 42, and fixing bolts 43. The lugs 41 are located at two opposite sides of the plug housing 22, and the notches 42 are located at two opposite sides of the socket housing 12. The positions of the lugs 41 and the notches 42 are opposite. Of course, the positions of the two can also be set to be reversed. The specific fixing method is to insert the lug 41 into the notch 42, and the fixing bolt 43 is screwed from the notch 42 into the lug 41 to form guiding and fixing. The contact position between the lug 41 and the notch 42 forms a contact surface with a cross-section similar to a "ji" character. The contact surface includes a rectangular opening 44 at the top and inclined surfaces 45 in an "eight" shape on both sides of the rectangular opening 44. Specifically, the notch 42 has an open entrance and a defined rectangular opening 44. The entrance is composed of an inclined surface 45 that gradually narrows from the entrance to the rectangular opening 44. On the other hand, the lug 41 has a size and shape that matches the notch 42 to ensure the best fixing state after complete embedding. During plugging, the operator first aligns the lug 41 with the entrance of the notch 42. Due to the existence of the inclined surface 45, even with a certain angular deviation, the lug 41 can naturally adjust its direction during the insertion process and slide along the inclined surface 45 until it touches the straight wall part of the rectangular opening 44. When the front end of the lug 41 touches the straight wall of the rectangular opening 44, it means that the predetermined final position has been reached. At this time, the contact between the lug 41 and the notch 42 becomes vertical or nearly vertical, ensuring the maximum contact area and stability between the two components. Then, through fasteners such as the fixing bolt 43, it penetrates from the top of the notch 42 and is screwed into the lug 41 to complete the final fastening connection, thus ensuring the firmness of the connection and preventing loosening when subjected to external forces or vibrations. In addition, there are two fixing devices 4, which are respectively located at two opposite sides in the length direction of the socket assembly 1 and the plug assembly 2. The opposite surfaces of the two lugs 41 form inwardly inclined guide surfaces 411. Taking the lugs 41 located at two opposite sides of the plug housing 22 as an example, the inclined guide surfaces 411 on both sides form a constricted opening that gradually narrows towards the direction close to the plug housing. During plugging, the inclined guide surfaces 411 contact the bottom edges of the two opposite sides of the socket housing 12, and can guide the plug assembly 2 to gradually align with the socket assembly 1 to ensure accurate plugging of the socket assembly 1 and the plug assembly 3.

[0043] As Figure 6 , 7 shown, the plug strip 21 further includes a main body section 212. An angle of 90° to 180° is formed between the main body section 212 and the plug strip connection end 211. In the figure, the angle is 135° to adapt to a specific installation space.

[0044] As Figure 1-4As shown, a bushing 14 is fixedly installed in the socket housing 12, and the socket strip 11 is plugged and installed in the bushing 14. The socket strip 11 has at least two, and the socket strip 11 is exposed at the socket housing 12 to form an external terminal 112, and adjacent external terminals 112 are staggered in opposite directions. In the figure, there are two socket strips 11 and two plug strips 21, and the number depends on the circuit line requirements. The opposite direction referred to above can be upward or downward in the thickness direction or left or right in the width direction. In short, it is an extension in the opposite direction, so that the external terminal 112 used to connect the cable is appropriately far away, which can reduce the risk of electromagnetic interference between adjacent external terminals 112 and improve the safety of use and heat dissipation efficiency of the connector.

[0045] like Figure 2-6 As shown, the socket housing 12 is provided with a connection port 121 exposing the inner connection end 111 of the socket row, and the plug housing 22 is provided with a protruding boss 23, the plug row connection end 211 is exposed at the table of the boss 23, and the boss and the connection port 121 are adapted to form a limit. This ensures that the plug assembly 2 and the socket assembly 1 can be highly accurately aligned when connected, so that the two can be firmly connected, and poor contact caused by displacement or vibration during the connection process is avoided.

[0046] like Figure 6 As shown, the boss 23 has a limiting column 231, and a notch 213 is provided at the plug row connection end 211. The limiting column 231 is inserted into the notch 213 to form a limiting fit to limit the plug row 21. The limiting column 231 ensures that it can be smoothly inserted into the notch 213, while providing sufficient lateral limiting force. The notch 213 can be designed to be in a rectangular shape, which can form a fit with the limiting column 231. When the plug assembly 2 is inserted into the socket assembly 1, the limiting column 231 is inserted into the notch 213 from the thickness direction of the plug row connection end 211 upward and downward. This process not only plays a guiding role, but also limits the movement of the plug in the horizontal direction, ensuring the correct alignment of the plug and the socket, and avoiding displacement during assembly.

[0047] like Figure 2 , 3As shown in FIGS. 6, 8 and 9, a lining member 24 is also installed in the plug housing 22. The inner side wall of the lining member 24 has a flange 242. The boss member 23 is integrally provided with a buckle 232. The buckle 232 is snap-connected with the flange 242 to fix the boss member 23 and the lining member 24. The lining member 24 is fixed by snap-connection, which increases the stability of the internal structure of the housing. The lining member 24 is fixed with a support platform 241, which is located below the plug row connection end 211 to support the plug row connection end 211. When the plug assembly 2 is connected, the plug assembly 2 is bound to receive the pressure of the socket strip 11, and the support platform 241 contacts the bottom surface of the plug row connection end 211, forming a stable support structure for it. This not only enhances the vibration resistance of the plug strip 21 and reduces the contact looseness caused by vibration, but also helps to maintain the flatness of the plug row connection end 211 and ensure the reliability of electrical contact.

[0048] The socket strip 11 and the plug strip 21 are mainly made of copper, which can be pure copper or copper-based alloy. In this way, copper is selected as the main material to make full use of its low resistance, high thermal conductivity and good processability, further enhancing the current transmission efficiency and heat dissipation performance of the connector.

[0049] like Figure 1-3 As shown, the socket housing 12 is provided with a locking opening 122, which is located at the position of the locking member 3. The locking opening 122 is covered with a flip cover 13, which is hingedly mounted on the socket housing 12. The flip cover 13 is opened to open the locking opening 122, and the locking member 3 can be tightened to fasten the socket strip 11 and the plug strip 21, which is convenient for users to operate and maintain the locking member 3, and also improves the daily use safety and dustproof and waterproof performance of the connector.

[0050] Another embodiment: Different from the above embodiment, Fig.10 , 11As shown, the fixing device 4 includes a tapered column 46 and a guide hole 47, and the tapered column 46 is inserted into the guide hole 47 to form a fixation. The fixing device 4 is simpler and more efficient, and is particularly suitable for occasions that are easy to assemble and disassemble. One end of the tapered column 46 is wider and the other end is narrower. The overall shape is conical or similar to a cone. This design is easy to insert and can be automatically centered. A guide hole 47 matching the tapered column 46 is machined in the part that needs to be fixed. The guide hole 47 is usually a straight cylinder, and the bottom can be flat or slightly enlarged to better accommodate the wide end of the tapered column 46 to ensure stability after fixation. During assembly, first ensure that the tapered column 46 is correctly aligned with the guide hole 47. Due to the tapered design, even if the initial alignment is not completely accurate, the tapered column 46 can adjust the centering by itself during the insertion process; applying an appropriate amount of axial pressure, the tapered column 46 will gradually penetrate into the guide hole 47. As the insertion depth increases, the contact area increases, and the fixing force increases accordingly, until the widest end of the tapered column 46 is in close contact with the bottom or enlarged portion of the guide hole 47. In order to prevent loosening, a fastening bolt can be provided on one side of the tapered column 46 to ensure the firmness of the connection between the socket assembly 1 and the plug assembly 2.

[0051] like Fig.10 , 11 As shown, a 90° angle is formed between the main body section 212 and the plug row connection end 211, which means that when the plug assembly 2 is connected to the socket assembly 1, the main parts of the two will be in a vertically distributed state. This is also a common choice for application scenarios, which can save installation space and improve wiring flexibility and efficiency.
