Description

Technical Field

[0001] This invention belongs to the field of copper busbar harness connectors, specifically a copper busbar harness connector for new energy batteries. Background Technology

[0002] New energy batteries are rechargeable batteries that provide driving power for new energy vehicles, energy storage systems, and other equipment, and are one of the most critical components of new energy vehicles. During the production and assembly process of new energy batteries, copper busbar harness connectors are frequently required.

[0003] Patent CN220797012U discloses an easy-to-install copper busbar harness connector, belonging to the field of copper busbar harness connectors. It includes a busbar with a copper busbar harness connector female and male sockets mounted on it. The female socket is mounted on the busbar via two symmetrically arranged fixing structures. Each fixing structure consists of a spring, a main plate, and a baffle. There are two main plates symmetrically mounted at both ends of the spring, and two baffles mounted at the lower ends of the two main plates. A limiting structure is installed on the female socket and the two fixing structures. The limiting structure consists of a connecting rod and two U-shaped limiting blocks symmetrically mounted at both ends of the connecting rod. By setting the fixing structure on the female socket and the limiting structure on the female socket and the fixing structure, the female socket can be easily installed and fixed onto the busbar.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] The copper busbar harness is connected by inserting its end into the socket and then securing it in place. However, even after insertion, a gap may remain between the harness end and the socket. During subsequent use, dust and other impurities can easily enter the socket through this gap. When these impurities accumulate, they can affect the circuit's continuity. Furthermore, if the direction of force applied to the harness end is not parallel to the insertion / removal direction when plugging or unplugging, the harness end may be damaged due to pressure against the socket's inner wall, affecting subsequent use. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a copper busbar harness connector for new energy batteries.

[0008] The connection auxiliary assembly includes a fixing plate fixedly connected to one side of the upper surface of the socket. A limiting rod is fixedly connected to one side of the fixing plate. A first fitting block is slidably connected to the limiting rod. Multiple displacement rods are slidably connected to the mounting base via sliding grooves.

A first sliding rod is slidably connected to one side of the first fitting block. A first connecting block is fixedly connected to one end of the first sliding rod. A first pulley is rotatably mounted on one side of the first connecting block. A third sliding rod is slidably connected to one side of the second fitting block. A second connecting block is fixedly connected to one end of the third sliding rod. A second pulley is rotatably mounted on one side of the second connecting block.

[0009] Preferably, mounting holes are provided on both sides of the mounting base.

[0010] Preferably, one end of the bonding block is threadedly connected to a threaded rod, both ends of which are rotatably mounted on the socket, and one end of the threaded rod is provided with a rotating handle.

[0011] Preferably, a connecting rod is rotatably provided on one side of the second bonding block, and a threaded block is rotatably provided on one end of the connecting rod.

[0012] Preferably, a threaded rod is threadedly connected to one side of the threaded block, and one end of the threaded rod is rotatably mounted on the mounting base.

[0013] Preferably, a spring is sleeved on one side of the slide rod, one end of the spring is fixedly connected to the end of the slide rod, and the other end is fixedly connected to one side of the bonding block.

[0014] Preferably, a second spring is sleeved on one side of the slide rod three, one end of the second spring is fixedly connected to one end of the slide rod three, and the other end is fixedly connected to one side of the bonding block two.

[0015] Preferably, a sealing gasket is provided on one lower end face of the bonding block, and a sealing gasket is provided on one side end face of the bonding block.

[0016] Preferably, it also includes an accidental loosening alarm component;

[0017] The accidental loosening alarm assembly includes a cam fixedly connected to a pulley, the cam being rotatably mounted on a connecting block, a slide rod slidably connected to one side of the connecting block, a fixing block fixedly connected to one end of the slide rod slidably, a pressure sensor being provided on one side of the fixing block, and multiple alarm lights being provided on the mounting base, the pressure sensor being electrically connected to the alarm lights.

[0018] Preferably, a threaded rod three is rotatably provided on one side of the upper end of the fixing block, and the threaded rod three is threadedly connected to the connecting block one.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The copper busbar harness connector for new energy batteries described in this invention utilizes a connection auxiliary component. The end of the copper busbar harness is fixed in place by the cooperative action of two bonding blocks. Furthermore, because the sealing gaskets one and two fill the gap between the end of the copper busbar harness and the socket, it effectively prevents dust and other impurities from entering the gap and affecting circuit continuity. Moreover, while the bonding blocks one and two are in contact with the end of the copper busbar harness, they also provide a fixing effect, thus preventing the end of the copper busbar harness from detaching due to accidental force. Furthermore, during the insertion and removal of the copper busbar harness end, pulleys two and one will remain in contact with the copper busbar harness end under the action of springs two and one, respectively. The copper busbar harness end is limited by pulleys one and two. Since this contact method is elastic, the copper busbar harness end can move in the socket and also remain horizontal under the limiting action. This ensures that when the operator inserts or removes the copper busbar harness end, the copper busbar harness end will not be damaged because the direction of force is not parallel to the insertion or removal direction, thus preventing the copper busbar harness end from pressing against the inner wall of the socket.

[0021] 2. The copper busbar harness connector for new energy batteries described in this invention utilizes an accidental loosening alarm component. When the end of the copper busbar harness is fixed, a pressure sensor is brought close to and in contact with a cam until the pressure sensor detects pressure. At this point, this pressure value is set as the initial value, and the initial value information is recorded in the alarm light. Because the pulley one maintains a tight fit with the surface of the copper busbar harness end, when the end of the copper busbar harness becomes loose, friction is formed between the pulley one and the surface of the end of the copper busbar harness, causing the pulley one and the cam to rotate synchronously. Due to the irregular shape of the cam, the cam may press against or move away from the pressure sensor. In either case, the pressure value detected by the pressure sensor will deviate from the initial value, and the pressure change information is transmitted to the alarm light, which then illuminates to alert nearby personnel and allow for timely action. This prevents situations where nearby personnel are unaware of accidental loosening of the copper busbar harness end, thus affecting normal use. Attached Figure Description

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please refer to Figures 1-7 The present invention provides a technical solution: a copper busbar harness connector for new energy batteries, including a mounting base 1, on which a plurality of sockets 4 are horizontally equidistantly distributed and fixedly connected, and the sockets 4 are also provided with connection auxiliary components;

[0033] The connecting auxiliary components include a fixing plate 5 fixedly connected to one side of the upper surface of the socket 4. A limiting rod 13 is fixedly connected to one side of the fixing plate 5. A first fitting block 6 is slidably connected to the limiting rod 13. Multiple displacement rods 10 are slidably connected to the mounting base 1 via a sliding groove 30. A second fitting block 7 is fixedly connected to the upper end of the displacement rod 10. One side of each socket 4 is in contact with the surfaces of two second fitting blocks 7. A first sliding rod 17 is slidably connected to one side of the first fitting block 6. A first connecting block 19 is fixedly connected to one end of the first sliding rod 17. A first pulley 20 is rotatably mounted on one side of the first connecting block 19. A third sliding rod 28 is slidably connected to one side of the second fitting block 7. A second connecting block 27 is fixedly connected to one end of the third sliding rod 28. A second pulley 26 is rotatably mounted on one side of the second connecting block 27.

[0034] In this embodiment, as Figures 2-4 , Figure 6 , Figure 7 As shown, mounting holes 2 are provided on both sides of the mounting base 1.

[0035] One end of the bonding block 6 is threadedly connected to a threaded rod 12. Both ends of the threaded rod 12 are rotatably mounted on the socket 4. One end of the threaded rod 12 is provided with a rotating handle 11.

[0036] A connecting rod 16 is rotatably mounted on one side of the bonding block 2 7, and a threaded block 9 is rotatably mounted on one end of the connecting rod 16.

[0037] One side of the threaded block 9 is threadedly connected to a threaded rod 8, and one end of the threaded rod 8 is rotatably mounted on the mounting base 1.

[0038] A spring 18 is fitted on one side of the slide rod 17. One end of the spring 18 is fixedly connected to the end of the slide rod 17, and the other end is fixedly connected to one side of the mating block 6.

[0039] A spring 29 is fitted on one side of the slide bar 3 28. One end of the spring 29 is fixedly connected to one end of the slide bar 3 28, and the other end is fixedly connected to one side of the mating block 2 7.

[0040] A sealing gasket 14 is provided on the lower end face of the bonding block 6, and a sealing gasket 25 is provided on one side end face of the bonding block 7.

[0041] Specifically, in existing copper busbar harness connectors, the end of the copper busbar harness is inserted into the socket 4 and then fixed in place to achieve connection. However, even after insertion, a gap remains between the end of the copper busbar harness and the socket 4. During subsequent use, dust and other impurities can easily enter the socket 4 through this gap. When these impurities accumulate to a certain amount, they can affect circuit continuity. Furthermore, if the direction of force applied to the end of the copper busbar harness is not parallel to the insertion / removal direction when inserting or removing it, the end of the copper busbar harness can easily be damaged due to pressure against the inner wall of the socket 4, thus affecting subsequent use.

[0042] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0043] Mounting base 1 is installed in the designated position using mounting holes 2 and bolts. Since mounting base 1 is equipped with multiple sockets 4, the ends of multiple copper busbars can be inserted into the sockets 4. After the ends of the copper busbars are inserted, rotating handle 11 rotates threaded rod 12, causing contact block 6 to descend and contact with the ends of the copper busbars. Sealing gasket 14 will then be tightly contacted with the ends of the copper busbars under the action of contact block 6. Subsequently, rotating threaded rod 8 moves threaded block 9, which in turn moves two adjacent contact blocks 7 closer together via connecting rod 16 until sealing gasket 15 is also in contact with the side of the ends of the copper busbars. At this point, the ends of the copper busbars are fixed in place by the cooperation of contact blocks 6 and 7. Furthermore, since sealing gasket 14 and sealing gasket 15 fill the gap between the ends of the copper busbars and the sockets 4, it effectively prevents dust and other impurities from entering the gap and affecting the circuit connection. Furthermore, while the first bonding block 6 and the second bonding block 7 are in contact with the end of the copper busbar harness, they also fix the end of the copper busbar harness, thereby preventing the end of the copper busbar harness from falling off due to accidental force.

[0044] Furthermore, during the insertion and removal of the copper busbar harness end, a certain gap is maintained between the copper busbar harness end and the first contact block 6 and the second contact block 7. At this time, the second pulley 26 and the first pulley 20 will be in contact with the copper busbar harness end under the action of the second spring 29 and the first spring 18, respectively. The copper busbar harness end is limited by the first pulley 20 and the second pulley 26. Since this contact method is elastic, the copper busbar harness end can move in the socket 4 and also remain horizontal under the action of the limit. This ensures that when the operator inserts or removes the copper busbar harness end, the copper busbar harness end will not be damaged because the direction of force is not parallel to the insertion or removal direction, which would cause the copper busbar harness end to squeeze the inner wall of the socket 4.

[0045] In this embodiment, as Figure 5 As shown, it also includes an accidental loosening alarm component;

[0046] The accidental loosening alarm assembly includes a cam 25 fixedly connected to a pulley 20. The cam 25 is rotatably mounted on a connecting block 19. A slide rod 22 is slidably connected to one side of the connecting block 19. A fixing block 23 is fixedly connected to one end of the slide rod 22. A pressure sensor 24 is provided on one side of the fixing block 23. Multiple alarm lights 3 are provided on the mounting base 1. The pressure sensor 24 is electrically connected to the alarm lights 3.

[0047] A threaded rod 21 is rotatably mounted on one side of the upper end of the fixed block 23, and the threaded rod 21 is threadedly connected to the connecting block 19.

[0048] Specifically, in the above embodiments, although the connection and fixation of the copper busbar harness end can be achieved, even if the copper busbar harness end is fixed, the copper busbar harness end may be forcibly detached from the socket 4 due to accidental external force. When the copper busbar harness end is detached from the socket 4, it may not be easy for people around to know, thus affecting normal use.

[0049] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0050] After the copper busbar harness end is fixed, pulley 20 is stationary. Then, threaded rod 21 is rotated to bring pressure sensor 24 close to and into contact with cam 25 until pressure sensor 24 detects pressure. At this point, this pressure value is set as the initial value, and the initial value information is recorded in alarm light 3. Because pulley 20 is in close contact with the surface of the copper busbar harness end, when the copper busbar harness end becomes loose, friction is formed between pulley 20 and the surface of the copper busbar harness end, causing pulley 20 and cam 25 to rotate synchronously. Due to the irregular shape of cam 25, cam 25 may press against or move away from pressure sensor 24. In either case, the pressure value detected by pressure sensor 24 will deviate from the initial value, and the pressure value change information will be transmitted to alarm light 3, which will then illuminate to alert nearby personnel and allow them to take timely measures. This avoids situations where nearby personnel are not notified in time of accidental loosening of the copper busbar harness end, thus affecting normal use.

[0051] Working principle: The mounting base 1 is installed in the designated position through the mounting hole 2 and the bolt. Since the mounting base 1 is equipped with multiple sockets 4, the ends of multiple copper busbars can be inserted into the sockets 4. After the ends of the copper busbars are inserted, the threaded rod 12 is rotated by rotating the handle 11, causing the first contact block 6 to descend and contact with the ends of the copper busbars. The first sealing gasket 14 will then be tightly contacted with the ends of the copper busbars under the action of the first contact block 6. Subsequently, the threaded rod 8 is rotated, which drives the threaded block 9 to move. This causes the two adjacent second contact blocks 7 to move closer to each other through the connecting rod 16 until the second sealing gasket 15 is also in contact with the side of the ends of the copper busbars. At this time, the ends of the copper busbars are fixed by the cooperation of the first contact block 6 and the second contact block 7. Furthermore, since the first sealing gasket 14 and the second sealing gasket 15 fill the gap between the ends of the copper busbars and the sockets 4, it effectively prevents dust and other impurities from entering the gap and affecting the circuit connection. Furthermore, while the first and second contact blocks 6 and 7 are in contact with the ends of the copper busbar harness, they also fix the ends of the copper busbar harness, thus preventing them from falling off due to accidental force. During the insertion and removal of the copper busbar harness ends, a certain gap is maintained between the ends of the copper busbar harness and the first and second contact blocks 6 and 7. At this time, pulleys 26 and 20 will remain in contact with the ends of the copper busbar harness under the action of springs 29 and 18, respectively. The ends of the copper busbar harness are limited by pulleys 20 and 26. Because this contact method is elastic, the ends of the copper busbar harness can move within the socket 4 and remain horizontal under the limiting effect. This prevents the ends of the copper busbar harness from being damaged due to the force direction being non-parallel to the insertion / removal direction, which could cause the ends of the copper busbar harness to press against the inner wall of the socket 4. After the copper busbar harness end is fixed, pulley 20 is stationary. Then, threaded rod 21 is rotated to bring pressure sensor 24 close to and into contact with cam 25 until pressure sensor 24 detects pressure. At this point, this pressure value is set as the initial value, and the initial value information is recorded in alarm light 3. Because pulley 20 is in close contact with the surface of the copper busbar harness end, when the copper busbar harness end becomes loose, friction is formed between pulley 20 and the surface of the copper busbar harness end, causing pulley 20 and cam 25 to rotate synchronously. Due to the irregular shape of cam 25, cam 25 may press against or move away from pressure sensor 24. In either case, the pressure value detected by pressure sensor 24 will deviate from the initial value, and the pressure value change information will be transmitted to alarm light 3, which will then illuminate to alert nearby personnel and allow them to take timely measures. This avoids situations where nearby personnel are not notified in time of accidental loosening of the copper busbar harness end, thus affecting normal use.
