Description

Technical Field

[0001] This utility model relates to the field of power battery systems, and in particular to an electrical connection component for a battery balancing harness. Background Technology

[0002] With the rapid development of electric vehicles and renewable energy storage systems, battery balancing technology, as a key technology to ensure stable battery pack performance and extend battery life, directly affects the efficiency and reliability of battery balancing through the design of its electrical connection components. Existing battery balancing harnesses often employ simple plug-in or soldering methods, which are prone to poor contact or loosening under long-term use or exposure to external forces such as vibration and impact. This not only affects the effectiveness of battery balancing but may also lead to electrical faults, endangering the safety of the battery pack.

[0003] Secondly, existing battery balancing harnesses often lack effective protection for battery terminals during electrical connection. These terminals are easily damaged during the connection process, leading to poor contact or short circuits. This not only affects the effectiveness of battery balancing but may also cause permanent damage to the battery pack. Utility Model Content

[0004] The purpose of this invention is to provide an electrical connection component for a battery balancing harness, which solves the problems of insufficient connection reliability, inconvenient installation and maintenance, and insufficient protection of the terminals in the existing battery balancing harness during electrical connection.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An electrical connection assembly for a battery equalization harness includes a connector. A plurality of connecting wires are provided on one side of the connector. Each connecting wire is used for electrical connection to the positive or negative terminal of a single cell of the battery. Each connecting wire has a connecting cap at its end. The connecting cap has an oval-shaped inner cavity and is used to be fitted onto the terminal of the positive or negative terminal of the battery. A short rod is threaded into the inside of the connecting cap. A pressing block is fixedly connected to the bottom end of the short rod. The axes of the short rod and the pressing block are offset. When the short rod rotates inside the connecting cap, the pressing block can apply a pressing force to the terminal, which drives the terminal to move towards the smaller end of the oval-shaped inner cavity of the connecting cap.

[0006] Preferably, a knob is fixedly connected to the top of the short rod, which allows the operator to manually rotate the short rod to apply pressure to the terminal block through the eccentric pressing block at the bottom of the short rod.

[0007] Preferably, the top of the knob has a cross-shaped groove for use with a Phillips screwdriver or a hand tool with a Phillips head, so that the operator can rotate the knob more conveniently and effortlessly.

[0008] Preferably, one side of the connector is provided with a cable management piece, and the top of the cable management piece is fixedly connected with cable management rods at equal intervals. The connecting wires are respectively embedded between two corresponding connected cable management rods. Each connecting wire is embedded in a wire groove formed by two adjacent cable management rods, so that the connecting wires can be arranged and fixed in an orderly manner, avoiding mutual tangling or crossing.

[0009] Preferably, the ends of the cable management rod are spherical, making the ends of the cable management rod smoother, reducing friction and damage between the cable and the connecting cable, and protecting the integrity of the connecting cable.

[0010] Preferably, the oval-shaped inner surface of the connector cap is provided with anti-slip texture to increase the friction between the connector cap and the terminal block and prevent the connector cap from slipping off when subjected to force.

[0011] Preferably, the knob has anti-slip texture to increase the friction between the knob and the finger and prevent the knob from slipping when rotating.

[0012] Preferably, the connector has round holes at all four corners to facilitate the fixed installation of the connector.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model achieves a tight clamping of the terminal block by using the oval inner cavity of the connecting cap to cooperate with the battery terminal, as well as the design of the short rod and the compression block. This ensures a reliable electrical connection between the battery equalization harness and the battery cell, and effectively prevents electrical faults caused by loose connections or poor contact.

[0015] 2. This utility model allows operators to easily rotate the short rod by setting a knob, thereby adjusting the squeezing force of the squeezing block on the terminal block, simplifying the installation process. At the same time, the combination design of the cable management piece and cable management rod effectively organizes the connecting wires, improves the neatness and aesthetics of the components, and also facilitates the installation, maintenance and replacement of the connecting wires.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3 This embodiment provides an electrical connection assembly for a battery equalization harness, including a connector 1. A plurality of connecting wires 2 are provided on one side of the connector 1. Each connecting wire 2 is used to electrically connect to the positive or negative terminal of a single cell of the battery. Each end of the connecting wire 2 is provided with a connecting cap 3. The connecting cap 3 has an oval-shaped inner cavity. The connecting cap 3 is used to be fitted onto the terminal of the positive or negative terminal of the battery. A short rod 4 is threaded inside the connecting cap 3. A pressing block 5 is fixedly connected to the bottom end of the short rod 4. The axes of the short rod 4 and the pressing block 5 are offset. When the short rod 4 rotates inside the connecting cap 3, the pressing block 5 can apply a pressing force to the terminal. The pressing force drives the terminal to move toward the small end of the oval-shaped inner cavity of the connecting cap 3.

[0022] When the short rod 4 rotates inside the connecting cap 3, the eccentric pressing block 5 can apply a pressing force to the terminal. This pressing force drives the terminal to move towards the small end of the oval inner cavity of the connecting cap 3. Through the bidirectional pressing between the oval inner cavity of the connecting cap 3 and the pressing block 5, the connecting cap 3 is firmly fixed to the terminal, realizing a reliable electrical connection between the battery equalization harness and the battery cell.

[0023] A knob 6 is fixedly connected to the top of the short rod 4. By rotating the knob 6, the short rod 4 can be driven to rotate inside the connecting cap 3, thereby causing the pressing block 5 to apply pressure to the terminal block, thus achieving a tight connection between the connecting cap 3 and the terminal block.

[0024] The top of the knob 6 has a cross groove 7, which works with a Phillips screwdriver or a hand tool with a Phillips head, making it easier and more convenient to rotate the knob 6, and improving the operability of the knob 6, especially when precise control of the rotation force or angle is required.

[0025] One side of the connector 1 is provided with a cable management piece 8, and the top of the cable management piece 8 is fixedly connected with cable management rods 9 at equal intervals. The connecting wires 2 are respectively embedded between the two corresponding cable management rods 9. The combination of the cable management piece 8 and the cable management rods 9 effectively organizes the connecting wires 2, prevents them from being messy, and improves the neatness and aesthetics of the electrical connection components of the battery equalization harness.

[0026] The two ends of the cable management rod 9 are spherical, which reduces friction and damage between the cable management rod 9 and the connecting line 2, protects the integrity of the connecting line 2, and makes the connecting line 2 easier to insert or pull out of the cable management rod 9, thus improving the convenience of operation.

[0027] The oval-shaped inner surface of the connector cap 3 is provided with anti-slip texture. The anti-slip texture increases the friction between the connector cap 3 and the terminal block, preventing the connector cap 3 from slipping off when subjected to force.

[0028] The knob 6 has anti-slip texture, which increases the friction between the knob 6 and the fingers and prevents the knob 6 from slipping during rotation.

[0029] The connector 1 has round holes 10 at each of its four corners. The round holes 10 facilitate the fixing of the connector 1. By passing screws or other fasteners through the round holes 10, the connector 1 can be firmly fixed in the required position to prevent it from moving or falling off during use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
