Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to a metal strip connector. Background Technology

[0002] With the rapid growth of the electric vehicle market, the safety and stability of the connection devices for power batteries, as one of the core components of electric vehicles, are of paramount importance. Traditional connectors are typically made of conductive metal materials and insulating plastic materials, primarily used for electrical connections. However, these traditional connectors face significant electromagnetic challenges in the high-speed electromagnetic environment of a vehicle, leading to unstable signal transmission and potentially causing safety accidents.

[0003] While existing metal shields and shielded cables can effectively isolate electromagnetic interference, they increase overall weight and size. Furthermore, the larger the current carrying capacity of the cable, the larger its diameter needs to be, which is detrimental to in-vehicle installation and lightweight automotive design, and also increases costs. Additionally, although composite material connectors have improved weight reduction, they still struggle to completely eliminate electromagnetic interference during high-current transmission. Therefore, developing a connector that is both lightweight and provides highly efficient electromagnetic shielding has become an urgent need. Utility Model Content

[0004] This application provides a metal connector to solve the problems of current connectors being unable to eliminate electromagnetic interference when a car is traveling at high speed and the large weight of the shielded cable provided with the connector being detrimental to the lightweighting of the car.

[0005] A metal connector, comprising:

[0006] The bottom cover has a recessed receiving groove, and a connecting pipe extending away from the receiving groove is sleeved on the side wall of the bottom cover, and the connecting pipe communicates with the receiving groove;

[0007] A sleeve passes through the lower end of the bottom cover and extends into the receiving groove;

[0008] The top cover, fixed to the bottom cover, seals the receiving groove;

[0009] The metal busbar includes, from the inside out, a conductive busbar, a first insulating layer, a shielding layer, and a sheath. At both ends of the metal busbar, the shielding layer, the insulating layer, and the conductive busbar are exposed and close to the connecting pipe. The conductive busbar passes through the connecting pipe and extends into the receiving groove to communicate with the sleeve.

[0010] By adopting the above technical solution, a metal busbar connector is provided. One conductive busbar extends through a connecting tube into the receiving groove and is connected to the sleeve. The other conductive busbar is fixedly connected to the end of the sleeve away from the receiving groove. When the metal busbar connector is in operation, the first insulating layer and shielding layer on the outside of the conductive busbar can insulate and prevent the internal electromagnetic signals from leaking outward. At the same time, the bottom cover and top cover are both metal shells, which can also play an electromagnetic shielding role for the conductive busbar and sleeve in the receiving groove, ensuring the stability and reliability of the electronic system when the car is driving at high speed. In addition, the shielded cable originally provided in the connector is optimized and replaced with a metal busbar, which makes it thinner in the height direction, lighter in the car, and can save a certain amount of space.

[0011] In one embodiment, the metal busbar connector further includes an insulating layer disposed in the receiving groove and attached to the inner wall surface of the bottom cover. The insulating layer extends out of the bottom cover to form an insulating tube, and the sleeve passes through the insulating tube and abuts against the conductive busbar.

[0012] By adopting the above technical solution, the insulating layer can insulate the sleeve and, to a certain extent, block the coupling of electric and magnetic fields generated during current conduction, ensuring good electrical insulation between components at different potentials and avoiding problems such as signal distortion and malfunction caused by electromagnetic interference.

[0013] In one embodiment, the metal busbar connector further includes a bolt, the conductive busbar having a first through hole, the bolt passing through the first through hole, the sleeve, and the insulating tube to fix the metal busbar and the sleeve to the receiving groove.

[0014] By adopting the above technical solution, the use of bolts not only firmly fixes the metal components and sleeves in the receiving groove, preventing the components from loosening or shifting due to vibration and bumps during vehicle operation, but also serves to conduct current.

[0015] In one embodiment, the metal busbar is provided with a shielding layer and a shielding ring. The shielding layer is located at the end of the conductive busbar away from the receiving groove. The shielding ring is fitted over the shielding layer and is provided with an outwardly opening shielding spring. When the metal busbar extends into the connecting pipe, the shielding spring abuts against the inner wall surface of the connecting pipe.

[0016] By adopting the above technical solution, the shielding layer and shielding ring on the metal busbar further enhance the electromagnetic shielding effect. The shielding layer can effectively block the internal electromagnetic signals from radiating outward, while the shielding ring works in conjunction with the connecting tube to form a closed electromagnetic shielding space, providing good isolation against external interference. At the same time, the shielding spring of the shielding ring can provide cushioning when the metal busbar moves slightly, preventing the metal busbar from being damaged by colliding with the inner wall of the connecting tube, thus extending the service life of the metal busbar and the connector.

[0017] In one embodiment, the metal busbar connector further includes an abutment and a seal, the abutment being sleeved on the connecting tube, the abutment and the connecting tube abutting against both ends of the seal, the connecting tube being able to sleeve the seal so that the connecting tube and the metal busbar fit tightly together.

[0018] By adopting the above technical solution, the combination of the abutment and the sealing component provides an effective seal for the gap between the connecting tube and the metal assembly, which can prevent moisture, dust and other impurities from entering the connector, avoid short circuits and corrosion caused by moisture or dust accumulation, and ensure the long-term reliable operation of the connector.

[0019] In one embodiment, the abutting member is an abutting pipe, which includes a first kit, a connecting part, and a second kit. The first kit and the second kit are connected by the connecting part. The cross-sectional area of ​​the first kit is larger than that of the second kit. The first kit is fitted onto the connecting pipe, and the connecting part and the connecting pipe abut against the sealing member. The second kit is fitted onto the metal strip.

[0020] By adopting the above technical solution, the special structural design of the abutment pipe enables it to simultaneously accommodate the connecting pipe and the metal assembly, thereby achieving effective positioning and fixation of the sealing element.

[0021] In one embodiment, the first kit has a first snap-fit ​​portion, and the connecting tube has a second snap-fit ​​portion at one end near the abutment tube, with the first snap-fit ​​portion engaging with the second snap-fit ​​portion.

[0022] By adopting the above technical solution, the cooperation between the first snap-fit ​​part and the second snap-fit ​​part provides a simple and effective way to fix the abutment pipe on the connecting pipe.

[0023] In one embodiment, one of the first latching portion and the second latching portion is a latch and the other is a slot.

[0024] By adopting the above technical solution, this buckle and slot connection method is convenient and quick, making it easy to assemble on the automobile production line. At the same time, it can ensure that the position of the abutment pipe on the connecting pipe is accurate and stable, and ensure that the sealing effect of the seal is not affected.

[0025] In one embodiment, the seal is a sealing ring or sealing rubber.

[0026] By adopting the above technical solutions, the sealing ring usually has standardized dimensions and good sealing performance, making it suitable for occasions with high sealing accuracy requirements; the sealing rubber has better plasticity and adaptability, and can achieve a better sealing effect in some irregularly shaped gaps.

[0027] In one embodiment, the shielding layer is woven from copper wire or tin-plated copper wire.

[0028] By adopting the above technical solution, when the metal connector is conducting electricity, the shielding layer can play an electromagnetic shielding role, preventing interference when the car is driving at high speed.

[0029] In summary, this application includes at least one beneficial effect:

[0030] 1. One conductive bar extends into the receiving groove and is connected to the sleeve via a connecting tube. The other conductive bar is fixedly connected to the end of the sleeve away from the receiving groove. When the metal bar connector is in operation, the first insulating layer and shielding layer on the outside of the conductive bar can insulate and prevent internal electromagnetic signals from leaking outward. At the same time, the bottom cover and top cover are both metal shells, which can also play an electromagnetic shielding role for the conductive bar and sleeve in the receiving groove, ensuring the stability and reliability of the electronic system when the car is driving at high speed. In addition, the original shielded cable of the connector is optimized and replaced with a metal bar, which makes it thinner in the height direction, lighter in the car, and saves space.

[0031] 2. The combination of the abutment and the seal provides an effective seal between the connecting tube and the metal assembly, preventing moisture, dust and other impurities from entering the connector and avoiding problems such as short circuits and corrosion caused by moisture or dust accumulation, thus ensuring the long-term reliable operation of the connector.

[0032] 3. The shielding layer and shielding ring on the metal busbar further enhance the electromagnetic shielding effect. The shielding layer effectively blocks the radiation of internal electromagnetic signals outward, while the shielding ring works in conjunction with the connecting tube to form a closed electromagnetic shielding space, providing excellent isolation against external interference. Simultaneously, the shielding springs of the shielding ring provide cushioning when the metal busbar moves slightly, preventing damage from collisions with the inner wall of the connecting tube and extending the service life of both the metal busbar and the connector.

[0041] The following is in conjunction with the appendix Figure 1-7 The metal connector provided in this application will be described in further detail.

[0042] Example 1

[0043] Please see Figure 1-7 The present application provides a metal connector 1, which includes a bottom cover 11, a sleeve 12, a top cover 13 and metal components.

[0044] like Figures 1 to 2 As shown, the bottom cover 11 is recessed with a receiving groove 111, and the side wall of the bottom cover 11 is fitted with a connecting pipe 112 extending away from the receiving groove 111. The connecting pipe 112 communicates with the receiving groove 111.

[0045] Specifically, the bottom cover 11 includes a main body made of metal, with a recessed receiving groove 111. The shape of the receiving groove 111 can be adjusted according to the size of the metal components 14 to accommodate metal components 14 of different specifications. A connecting pipe 112 is sleeved on the side wall of the bottom cover 11. The length and diameter of the connecting pipe 112 can be selected according to actual needs. For example, the connecting pipe 112 can be made of stainless steel to enhance its corrosion resistance and mechanical strength. The connecting pipe 112 communicates with the receiving groove 111, ensuring that the metal components 14 can smoothly enter the receiving groove 111 through the connecting pipe 112.

[0046] like Figure 3 As shown, the sleeve 12 passes through the lower end of the bottom cover 11 and extends into the receiving groove 111. The sleeve 12 can be made of a material with good electrical conductivity, such as copper or aluminum, to ensure good electrical conductivity.

[0047] like Figure 4 As shown, the metal busbar 14 comprises, from the inside out, a conductive busbar 141, a first insulating layer 143, a shielding layer 144, and a sheath 145. At both ends of the metal busbar 14, the conductive busbar 141 is either copper or aluminum. The shielding layer 144, the first insulating layer 143, and the conductive busbar 141 are exposed sequentially and close to the connecting pipe 112. The first insulating layer 143 insulates the conductive busbar 141 and the shielding layer 144. The shielding layer 144 is woven from copper wire or tin-plated copper wire, enabling the metal busbar 14 to provide electromagnetic shielding when the vehicle is traveling at high speed. The weaving density and angle can be adjusted according to specific shielding requirements. For example, in environments with high electromagnetic shielding requirements, a higher weaving density is used to reduce the gaps between the metal wires, thus providing better shielding. The conductive busbar 141 is inserted through the connecting tube 112 and extends into the receiving groove 111 to conduct electricity with the sleeve 12. The first insulating layer 143 extends into the receiving groove 111. This can ensure a stable connection between the metal busbar 14 and the connector. At the same time, the good contact between the conductive busbar 141 and the sleeve 12 can reduce resistance and improve conductivity.

[0048] In addition, the bottom cover 11 may also include an insulating layer 113. The insulating layer 113 is disposed in the receiving groove 111 and attached to the inner wall surface of the bottom cover 11. A portion of the insulating layer 113 extends out from the bottom cover 11 to form an insulating tube 114. The sleeve 12 passes through the insulating tube 114 and abuts against the conductive busbar 141. The insulating layer 113 may be made of insulating materials such as polyethylene or polypropylene to prevent electromagnetic interference generated when the conductive busbar 141 is connected to the metal busbar 14, and at the same time, to isolate the current on the sleeve 12.

[0049] The connector may also include a top cover 13 and an upper cover 131. The upper cover 131 and the insulating layer 113 seal the receiving groove 111. The top cover 13 and the bottom cover 11 are fixed together to seal the upper cover 131 and the insulating layer 113. The top cover 13 may also be made of a metal material, such as aluminum alloy or stainless steel, to enhance its mechanical strength and corrosion resistance. The upper cover 131 may be made of an electromagnetic shielding material, which, together with the insulating layer 113, prevents electromagnetic interference when the metal assembly 14 is in contact with the sleeve 12. The top cover 13, the bottom cover 11, and the connector may be fixed by screws, clips, or other fixing structures. In this embodiment, the top cover 13 is hinged to one end of the connecting tube 112, and the top cover 13, the connecting tube 112, and the bottom cover 11 are fixed by screws. This allows for convenient inspection and maintenance of the internal components of the connector when the top cover 13 is opened.

[0050] The metal busbar connector 1 may further include a bolt 15. The conductive busbar 141 has a first through hole 142. The bolt 15 passes through the first through hole 142, the sleeve 12, and the insulating tube 114 to fix the metal busbar 14 and the sleeve 12 into the receiving groove 111. The bolt 15 may be made of high-strength steel to ensure a secure connection. The head of the bolt 15 may have anti-slip grooves to increase friction and prevent the bolt 15 from loosening.

[0051] like Figure 5 As shown, the metal assembly 14 is also provided with a shielding ring 16, on which a shielding layer 144 is fitted. The shielding ring 16 has shielding springs 161 that gradually open in the direction away from the receiving groove 111. When the metal assembly 14 extends into the connecting pipe 112, the shielding layer 144 extends into the connecting pipe 112, and the shielding springs 161 abut against the inner wall surface of the connecting pipe 112. The shielding ring 16 can be made of an elastic material, such as spring steel, to ensure that the shielding springs 161 can fit tightly against the inner wall of the connecting pipe 112, preventing damage to the metal assembly 14 during slight movement.

[0052] like Figure 6 As shown, the metal busbar connector 1 may also include an abutment 17 and a seal 18. The abutment 17 is fitted with a connecting tube 112. The abutment 17 and the connecting tube 112 abut against both ends of the seal 18. The connecting tube 112 can fit the seal 18 so that the connecting tube 112 and the metal busbar 14 are tightly fitted together.

[0053] Specifically, the abutment member 17 can be an abutment pipe 171, which includes a first fitting 172, a connecting part 173, and a second fitting 174. The first fitting 172 and the second fitting 174 are connected by the connecting part 173. The cross-sectional area of ​​the first fitting 172 is larger than that of the second fitting 174. The first fitting 172 is fitted with the connecting pipe 112, and the connecting part 173 and the connecting pipe 112 abut against the sealing member 18. The second fitting 174 is fitted with a metal strip 14. Both the first fitting 172 and the second fitting 174 can adopt a circular or square structure to accommodate connecting pipes 112 of different shapes. The connecting part 173 can adopt an arc-shaped or straight structure to ensure a good fit with the connecting pipe 112.

[0054] The first assembly 172 has a first snap-fit ​​portion 175, and the connecting tube 112 has a second snap-fit ​​portion 115 at the end near the abutment tube 171. The first snap-fit ​​portion 175 and the second snap-fit ​​portion 115 cooperate with each other. One of the first snap-fit ​​portion 175 and the second snap-fit ​​portion 115 is a buckle, and the other is a slot. The buckle can be made of plastic or metal, and the shape and size of the buckle and the slot are adapted to ensure a stable and reliable fit between the buckle and the slot.

[0055] The seal 18 can be a sealing ring or sealing rubber. The sealing ring can be made of rubber or silicone material, and the sealing rubber can be made of nitrile rubber or fluororubber material to ensure its good sealing performance.

[0056] like Figure 7 As shown, the lower end of the bottom cover 11 may also include a base plate 116, which is fixed to the bottom cover 11 by rivets. The insulating tube 114 and the sleeve 12 are both inserted through the base plate 116. The base plate 116 can be made of materials with electromagnetic shielding effects such as copper or aluminum. The end of the sleeve 12 away from the bottom cover 11 is used to abut against the conductive bar 141 of other metal components 14 to realize the conduction of the circuit.

[0057] The implementation principle of this embodiment is as follows: the metal busbar 14, through the connecting pipe 112, allows the conductive busbar 141 and the first insulating layer 143 to extend into the receiving groove 111. Then, bolts 15 fix the conductive busbar 141 and the sleeve 12. The end of the sleeve 12 away from the bottom cover 11 is fixed to the conductive busbar 141 of another metal busbar 14 by bolts 15, achieving good contact between the conductive busbar 141 and the sleeve 12 and ensuring conductivity. The shielding layer 144 and the shielding ring 16 are tightly attached to the inner wall of the connecting pipe 112. The shielding layer 144 provided on the metal busbar 14 provides electromagnetic shielding when the conductive busbar 141 is energized. At the same time, the conductive busbar 141 is located in the receiving groove 111, and the bottom cover 11 and the top cover 13 are both metal shells, which also have electromagnetic shielding effects, so that the car will not be interfered with when driving at high speed. The shielding spring 161 can buffer the metal busbar 14 and prevent damage to the surface of the metal busbar 14. The abutment 17 and the seal 18 ensure a tight fit between the connecting tube 112 and the metal strip 14, preventing water or dust ingress. In summary, the metal strip connector 1 of this embodiment not only has good electrical connection performance but also excellent electromagnetic shielding and protection capabilities. Furthermore, compared to previous connectors, it reduces weight to a certain extent, making the vehicle lighter and meeting the high-performance requirements of modern automotive electronic equipment.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
