Description

Technical Field

[0001] The utility model relates to the technical field of vehicle battery connectors, in particular to a copper connector for pressing a wire of an automobile battery. Background Art

[0002] The development of new energy vehicles has driven the evolution of automotive batteries. Battery crimping connectors connect the battery to the vehicle's electrical system, ensuring stable power transmission from the battery to the motor, control system, and other electrical components via the copper connector. However, in practice, issues remain regarding securing the crimping connectors to the battery and protecting them from dust, directly impacting the overall performance of the electrical system.

[0003] Electric vehicles are subject to vibrations from the road during driving, especially in harsh road conditions. Strong vibrations can cause the wire connectors to loosen, resulting in poor contact or even falling off. Loose wire connectors will increase contact resistance, which not only affects current transmission efficiency but also causes local heating, damaging the battery system and surrounding electrical components, and increasing the risk of fire.

[0004] Because automotive batteries are typically installed under the chassis or in the vehicle's engine compartment, these areas are subject to the intrusion of road dust, sand, and moisture. When dust and moisture penetrate the terminals of the crimping connector, they cause oxidation and corrosion of the wires, reducing their conductivity. The formation of an oxide layer increases contact resistance, thus affecting the stability of power transmission.

[0005] Once the crimping connector becomes loose or invaded by dust, the repair process will be time-consuming and labor-intensive. Therefore, it is necessary to design a copper crimping connector for automotive batteries to solve the problems existing in the current technology. Utility Model Content

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0043] See Figure 1-3As shown, this embodiment provides a copper connector for automobile battery wire crimping, comprising: a connector body 1, a positioning unit being provided on the connector body 1, the positioning unit comprising: a first positioning hole 11, a first groove 13, a serrated segment 14 and an anti-loosening washer 15, a first groove 13 being provided at the top of the first positioning hole 11, the first groove 13 being fixedly connected to the serrated segment 14, the serrated segment 14 being used to engage the battery connector, the anti-loosening washer 15 being fixedly connected to the bottom of the first positioning hole 11, the connector body 1 being further provided with a wire crimping unit 2, the connector body being further fixedly connected to a dustproof unit 3, the dustproof unit 3 comprising: a dustproof block 30 and a dustproof cover 31, the dustproof cover 31 being rotated on the dustproof block 30, and the dustproof unit 3 covering the wire crimping unit 2.

[0044] Specifically, the connector body 1 is the bearing structure of the wire-pressing copper connector. The connector body 1 is made of a highly conductive copper material, which can effectively reduce power loss to ensure low resistance and high conductivity. The connector body 1 is formed by cold forging in one step. It has ductility and plasticity, which is conducive to controlling its precision, reducing costs, and meeting the current transmission requirements of new energy vehicle batteries. The connector body 1 is formed by cold forging in one step, which improves the structural strength and can withstand the pulling force of the wiring harness. The positioning unit is used to firmly fix the wire-pressing copper connector on the battery connector to ensure that the wire-pressing copper connector will not loosen in the event of vibration or impact, thereby maintaining stable contact. The first positioning hole 11 is used to insert and fix the battery connector to ensure that it fits tightly with the battery connector without any gap. The bottom of the first positioning hole 11 is connected to an anti-loosening washer 15, which increases the friction with the battery connector and ensures the stability of the connection. The first groove 13 is located at the top of the first positioning hole 11 and is used to enhance the stability of the positioning unit. When the battery connector is inserted into the first positioning hole 11, the air pressure generated by the insertion is slowly released through the first groove 13 to prevent the situation where it cannot be squeezed in. The serrated segment 14 is fixedly connected in the first groove 13 and provides additional fixed support by generating a bite force with the surface of the battery connector. The serrated segment 14 adopts an inclined fine tooth structure, which can generate a large friction force when in contact with the battery connector, thereby limiting the sliding and rotation of the wire-pressing copper connector and avoiding the problem of poor contact caused by the wire-pressing copper connector sliding during use. The anti-loosening washer 15 is installed at the bottom of the first positioning hole 11. The anti-loosening washer 15 is a corrugated structure. When the wire-pressing copper connector is fixed to the battery connector, the anti-loosening washer 15 provides a certain elastic pressing force, thereby reducing the risk of the wire-pressing copper connector loosening. The anti-loosening washer 15 is selected from rubber material, which has good durability and wear resistance. The wire crimping unit 2 is responsible for firmly connecting the wiring harness to the connector body 1 to achieve stable transmission of current. The wire crimping unit 2 ensures reliable connection of the wiring harness, prevents displacement or loosening of the wiring harness, and ensures the overall safety and reliability of the wire crimping copper connector. The dustproof unit 3 is used to protect the wire crimping unit 2 and the wiring harness from dust and moisture, extending the service life of the wire crimping copper connector. The dustproof block 30 and the dustproof cover 31 work together to achieve sealed protection for the internal components of the wire crimping unit 2. The dustproof block 30 provides a support surface for the dustproof cover 31, and the dustproof cover 31 can rotate within the range of 0-90 degrees. The dustproof unit 3 can completely cover the wire crimping unit 2, playing a role in dustproof and waterproofing.

[0045] As you can understand, the copper connector for the wire crimping fits tightly against the battery connector via the positioning unit, preventing loosening caused by vibration or collision during driving, thereby ensuring reliable power transmission. The copper material of the connector body 1 and the wire crimping unit 2 ensures efficient power transmission. The dustproof unit 3 effectively blocks environmental damage to the wire crimping unit 2, extending the service life of the copper connector for the wire crimping.

[0046] In some examples of the present application, the positioning unit further includes: an opening 10 and a threaded segment 12, the first positioning hole 11 is provided with the opening 10, the bottom of the opening 10 is horizontally flush with the bottom of the connector body 1, the threaded segment 12 is provided outside the opening 10 and the first positioning hole 11, and the threaded segment 12 is used to engage the battery connector column.

[0047] Specifically, the first positioning hole 11 is provided with an opening 10, and the bottom of the opening 10 is flush with the bottom of the connector body 1, thereby ensuring the structural integration of the opening 10 and the connector body 1. The opening 10 increases the contact area with the battery connector, which is beneficial for the battery connector to be inserted into the first positioning hole 11, reduces the alignment time, and realizes the precise positioning of the battery connector. The threaded section 12 is distributed around the outside of the opening 10 and the first positioning hole 11, and is used to engage with the battery connector. The threaded section 12 can fit tightly with the battery connector column when the battery connector is inserted. The threaded section 12 not only improves the stability of the connection, but also facilitates quick installation and disassembly. The threaded section 12 and the serrated section 14 work together to ensure that the wire-pressing copper connector can maintain good contact with the battery connector in various environments.

[0048] As you can understand, the positioning unit provides a multi-level fixation, making the copper connector less likely to come loose due to vibration or impact during use, thereby ensuring the stability and safety of power transmission. This effectively avoids poor contact caused by loosening or displacement, while facilitating repeated installation and removal of the copper connector, improving its ease of use and durability.

[0049] In some examples of the present application, the wire pressing unit 2 includes: a wire pressing hole 20, a first chamfer 21 and a wire pressing block 22. The wire pressing hole 20 is a through hole. The wire pressing hole 20 is provided with several first chamfers 21. The inner wall of the wire pressing hole 20 is fixedly connected to several wire pressing blocks 22. The several wire pressing blocks 22 are axially symmetrical about the center of the wire pressing hole 20. The wire pressing blocks 22 are used to fix the wiring harness.

[0050] It is understandable that the wire pressing hole 20 is used to provide space for placing the wiring harness to prevent the wiring harness from being scattered and interfering with the normal operation of other electrical components. The first chamfers 21 are preferably 4, and the first chamfers 21 are used to reduce the friction generated by the wiring harness during the insertion process and provide smooth guidance, thereby facilitating the insertion and positioning of the wiring harness. The first chamfers 21 also effectively prevent the wiring harness from being scratched or damaged during the insertion process, thereby increasing the service life of the wiring harness. The wire pressing blocks 22 are preferably 2, and the two wire pressing blocks 22 are axially symmetrically distributed around the center of the wire pressing hole 20. The axially symmetrical distribution ensures that the wire pressing blocks 22 apply uniform pressure to the wiring harness, which not only stabilizes the position of the wiring harness, but also prevents it from loosening or shifting during use. When the wiring harness is inserted into the wire pressing hole 20, the wire pressing blocks 22 will fix it at multiple points to ensure that the wire pressing copper connector is fixed to the wiring harness.

[0051] In some examples of the present application, a copper connector for automobile battery crimping includes: a connector body 1 further includes a second groove 4, the second groove 4 is used to reserve space for wiring harnesses, and the connector body 1 further includes a third groove 5, the third groove 5 is used to reserve space for connection between the positioning unit and the battery.

[0052] Specifically, the second groove 4 provided on the connector body 1 provides sufficient space for the wiring harness, so that the wiring harness can be smoothly arranged and avoid being squeezed or bent. Through the reserved space, the second groove 4 effectively reduces the stress of the wiring harness during installation, reduces the risk of wear and breakage of the wiring harness, and thus extends the service life of the wiring harness. The connector body 1 is also provided with a third groove 5 for reserving the connection space between the positioning unit and the battery. The third groove 5 enables the positioning unit to be stably installed on the battery connector, avoiding installation deviation or looseness due to insufficient space, ensuring the firmness of the wire-pressing copper connector when connecting to the battery, and facilitating the precise docking of the positioning unit, thereby improving the connection efficiency and reliability of the wire-pressing copper connector.

[0053] It can be understood that the second groove 4 and the third groove 5 opened on the connector body 1 realize the management of the docking wire harness, the precise positioning and stable connection of the positioning unit, and ensure the efficient transmission of current by the crimping copper connector.

[0054] In some examples of the present application, the automobile battery wire-crimping copper connector includes: a dustproof block 30 is provided with a fourth groove 32, the fourth groove 32 provides a rotation space for the dustproof cover 31, the fourth groove 32 is provided with a locking hole 33, and a thread is provided inside the locking hole 33, and a dustproof hole 36 is provided on the upper part of the wire-crimping hole 20, the dustproof hole 36 is a through hole, and the dustproof hole 36 is consistent in size with the wire-crimping hole 20.

[0055] Specifically, the dustproof unit 3 is intended to achieve dustproof protection for the wire pressing unit 2, preventing dust or other particulate matter from entering the wiring harness and affecting the electrical performance. The function of the fourth groove 32 is to provide sufficient rotation space for the dustproof cover 31, ensuring that the dustproof cover 31 can be opened or closed smoothly, so as to effectively prevent dust and clean or repair the wire pressing unit 2 when necessary. The fourth groove 32 and the dustproof cover 31 can ensure a sealing effect when they fit together, preventing dust and moisture from entering the wire pressing unit 2 when closed. The locking hole 33 is used to fix the position of the dustproof cover 31, ensuring that the dustproof cover 31 can be firmly locked after closing, and preventing the dustproof cover 31 from accidentally opening due to external vibration or other factors. The interior of the locking hole 33 is provided with a thread, so that it can be used in conjunction with the corresponding bolt, and the dustproof cover 31 is reliably fixed by thread locking, thereby improving the dustproof effect. The thread of the locking hole 33 ensures the convenience of opening and closing the dustproof cover 31, and simplifies the operation process when the wire crimping unit 2 needs to be maintained or replaced. A dustproof hole 36 is set on the upper part of the wire crimping hole 20. The dustproof hole 36 is a through hole. The length and width of the dustproof hole 36 are consistent with the wire crimping hole 20. The size matching enables the dustproof hole 36 to achieve the dustproof function without affecting the normal function of the wire crimping hole 20. When the wiring harness is inserted into the wire crimping hole 20 of the wire crimping copper connector, the dustproof hole 36 forms a channel to prevent dust or moisture from entering the wiring area, and does not interfere with the insertion and installation of the wiring harness. When the dustproof cover 31 is closed, the dustproof hole 36 does not affect the fixation of the wiring harness, thereby achieving a dustproof effect.

[0056] It can be understood that the dustproof unit 3 ensures the dustproof effect of the crimping copper connector in various environments. The fourth groove 32 provides a flexible rotation space for the dustproof cover 31, so that it can be opened or closed according to needs. The locking hole 33 ensures the stability of the dustproof cover 31 through a threaded connection. The dustproof hole 36 not only ensures the normal installation of the wiring harness, but also prevents the entry of external particles, thereby improving the overall reliability and durability of the crimping copper connector.

[0057] In some instances of the present application, the dustproof unit 3 also includes: a second positioning hole 34 and a locking bolt 35. The dustproof cover 31 is provided with a second positioning hole 34, a thread is provided inside the second positioning hole 34, the apertures of the second positioning hole 34 and the locking hole 33 are consistent, and the locking bolt 35 is inserted into the second positioning hole 34 and the locking hole 33.

[0058] Specifically, the second positioning hole 34 and the locking bolt 35 enhance the stability and sealing performance of the dust cover 31. The interior of the second positioning hole 34 has a threaded structure, and the thread is used to tightly connect with the locking bolt 35 to ensure that the dust cover 31 will not loosen due to external vibration or other influencing factors after closing. The second positioning hole 34 is consistent with the aperture of the locking hole 33 of the dust block 30, so that the locking bolt 35 can smoothly pass through the second positioning hole 34 and be tightly connected with the locking hole 33. The locking bolt 35 is engaged with the threads of the second positioning hole 34 and the locking hole 33, ensuring the stability of the locking bolt 35 and reducing the difficulty or instability of the installation of the locking bolt 35 due to size mismatch. When the locking bolt 35 is inserted, the dust cover 31 and the dust block 30 are firmly connected by tightening the thread, thereby achieving a sealing effect, preventing dust or impurities from entering the wire pressing unit 2, and protecting the wire pressing unit 2 and the wiring harness connection area from the external environment. The locking bolt 35 plays a key locking role in the entire dustproof unit 3, and its function is more than just a simple connection. By using a threaded locking mechanism, the locking bolt 35 can withstand large external forces, preventing the dustproof cover 31 from loosening or shifting during use.

[0059] As will be appreciated, the second positioning hole 34, through its threaded engagement with the locking bolt 35, precisely positions the dust cover 31 on the dust block 30, preventing the dust cover 31 from shifting and affecting the dustproofing effect. The consistent diameters of the locking hole 33 and the second positioning hole 34 simplify the assembly of the dustproof unit 3 and ensure that the locking bolt 35 securely connects the second positioning hole 34 and the locking hole 33. This enhances the structural strength and durability of the dustproof unit 3, thereby improving the protective performance and service life of the copper crimping connector.

[0060] In some examples of the present application, in a copper connector for a car battery crimping wire, a connector body 1 is provided with a plurality of second chamfers 6 .

[0061] Specifically, the second chamfers 6 are preferably two, and the second chamfers 6 facilitate the installation and docking of the wire-pressing copper connector with the battery connector and the wiring harness. The rounded surface of the second chamfer 6 reduces the sharpness of the edge of the wire-pressing copper connector, thereby reducing the resistance during the connection process, allowing the wire-pressing copper connector to be smoothly inserted into the battery connector and connected to the wiring harness, reducing the difficulty of installing the wire-pressing copper connector and improving wiring efficiency. The second chamfer 6 also reduces the wear of the insulation layer of the docking wiring harness during the installation of the wire-pressing copper connector. The second chamfer 6 prevents the wiring harness from being squeezed or scratched by sharp edges at the wire-pressing copper connector, effectively preventing electrical failures caused by damage to the insulation layer and improving the reliability of the wire-pressing copper connector.

[0062] It can be understood that the second chamfer 6 is axially symmetrical about the connector body 1. The axially symmetrical distribution ensures that the force of the wire-pressing copper connector is evenly distributed in any direction, reduces the stress concentration caused by improper installation angle, helps to extend the service life of the wire-pressing copper connector, and improves the vibration and impact resistance of the wire-pressing copper connector.

[0063] In some examples of the present application, in a copper connector for a car battery wire crimping, the connector body 1 is fixedly connected to a wire fixing groove 7 , and the wire fixing groove 7 is provided with a third chamfer 8 .

[0064] Specifically, the wire fixing trough 7 ensures the fixation and support of the docking wire harness, and helps the copper wire connector to maintain the firmness and safety of the docking wire harness during use. The wire fixing trough 7 is provided with a third chamfer 8, which effectively reduces the wear of the wiring harness during installation and fixation. The third chamfer 8 makes the wiring harness less likely to be scratched or damaged by sharp edges when it is connected to the wire fixing trough 7, thereby better protecting the insulation layer of the wiring harness, alleviating the tension and bending force on the wiring harness in the wire fixing trough 7, and avoiding damage to the wiring harness caused by excessive pulling or friction. The third chamfer 8 increases the smoothness of the contact between the copper wire connector and the wiring harness, which helps the wiring harness maintain a stable position in the wire fixing trough 7 and prevents the wiring harness from loosening or falling off due to vibration or external force.

[0065] It can be understood that the wire fixing groove 7 and the third chamfer 8 optimize the installation of the wire-pressing copper connector for connecting the wire harness, and improve the wear resistance, firmness and durability of the wire-pressing copper connector.

[0066] In some examples of the present application, a copper connector for a car battery crimping line has a connector body 1 provided with a zinc layer.

[0067] It is understandable that the zinc layer forms a protective barrier on the connector body 1, which can effectively isolate the copper connector from direct contact with the external environment, preventing the copper material from being corroded, causing oxidation on the surface of the connector body 1 and affecting its service life. The zinc layer has excellent corrosion resistance and can form a dense oxide film on the surface of the connector body 1, thereby preventing the intrusion of corrosive media such as oxygen and moisture, and extending the service life of the copper connector. Moreover, the zinc layer has a good promoting effect on current conduction. The zinc layer can effectively reduce contact resistance, thereby ensuring smoother current transmission. Good conductivity can reduce the loss of electrical energy and improve the current transmission effect of the copper connector.

[0068] In summary, the beneficial effects of the present invention are as follows: the first positioning hole, the first groove and the serrated section in the positioning unit jointly ensure the stable connection between the wire-pressing copper connector and the battery connector. The first positioning hole improves the precise positioning of the wire-pressing copper connector to the battery connector, and the serrated section increases the friction between the wire-pressing copper connector and the battery connector, effectively preventing the wire-pressing copper connector from loosening due to vibration or impact after connection, thereby ensuring the stability of current transmission. The anti-loosening washer increases the locking effect on the battery connector, preventing the wire-pressing copper connector from sliding on the battery connector. When the anti-loosening washer is subjected to external impact or vibration, the anti-loosening washer provides additional fixing force, thereby improving the safety and reliability of the connection of the wire-pressing copper connector. The dustproof unit prevents dust, impurities and other external contaminants from entering the wire-pressing unit area, ensuring the cleanliness and dryness of the electrical connection area, reducing the risk of oxidation and corrosion of the wire-pressing copper connector, and extending the service life of the wire-pressing copper connector. The wire-pressing unit increases the stability of the wire-pressing copper connector and the wiring harness, reduces the power loss caused by looseness, and improves the stability and portability of the wire-pressing copper connector.
