[0001] This utility model relates to the field of wire harness technology, specifically to an anti-loosening energy storage wire harness. Background Technology

[0002] Energy storage harnesses are indispensable connecting components in energy storage systems. They are composed of various materials with special properties, including high-conductivity wires, high-quality insulation and shielding materials, and reliable connectors. Their main function is to achieve efficient power transmission and accurate signal transmission in energy storage systems, tightly connecting various key components such as battery packs, battery management systems, inverters, and charging and discharging equipment. Energy storage harnesses have characteristics such as high current carrying capacity, good insulation, anti-aging, and corrosion resistance, enabling them to adapt to complex and diverse application environments and ensuring the stable, safe, and reliable operation of energy storage systems. They play a crucial role in multiple fields such as renewable energy storage, grid energy storage, distributed energy storage, and electric vehicle energy storage.

[0003] During use, existing energy storage harnesses are prone to loosening between the harness and connectors due to various reasons such as movement and vibration, which can lead to failure in power transmission and signal transmission, affecting the normal operation of energy storage devices. To address this, we propose an anti-loosening energy storage harness. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-loosening energy storage harness, which can prevent the connection between the harness and the connector from becoming loose during the use of the energy storage harness, thereby improving the stability of power transmission and signal transmission and ensuring the stable operation of the energy storage device. It solves the problem that existing energy storage harnesses are prone to loosening between the harness and the connector due to movement, vibration and other reasons during use, which causes power transmission and signal transmission failure and affects the normal operation of the energy storage device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-loosening energy storage harness, comprising a harness body, a rotating ring, and a connector. A connecting slot is provided on one side of the outer surface of the connector. A connecting terminal is connected to one end of the harness body, and the connecting terminal is located inside the connecting slot. A T-shaped annular groove is provided on the outer surface of the connector near the connecting slot. Notches are provided on the inner wall of the T-shaped annular groove near the front and rear surfaces of the connector. The harness body passes through the rotating ring. T-shaped blocks are fixedly connected to the inner side of the rotating ring near the upper and lower surfaces via connecting rods. Through holes are provided on the outer side of the rotating ring near the front and rear surfaces. Sliding rods are inserted into both through holes. Limiting blocks are connected to the ends of both sliding rods near the connector. A helical spring is wound around the outer surface of both sliding rods.

[0006] Preferably, a limit ring is installed on the outer surface of the wire harness body near the inner side of the rotating ring.

[0007] Preferably, a movable ring is provided at the outer position of the rotating ring, and the ends of the two slide rods are both connected to the inner side of the movable ring, and the main body of the wire harness passes through the inside of the movable ring.

[0008] Preferably, the helical spring is located between the rotating ring and the limiting block.

[0009] Preferably, a step is provided on the outer surface of the connector near the edge of the connection slot, and a sealing ring is sleeved on the outer surface of the connection terminal, with the sealing ring located inside the step.

[0010] Preferably, a retaining ring is fitted onto the outer surface of the connecting terminal near the outer side of the sealing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a wire harness body, connector, connection slot, connection terminal, T-shaped annular groove, rotating ring, T-shaped block, slide rod, helical spring, through hole, notch, and limiting block, achieves the effect of preventing the connection between the wire harness and the connector from becoming loose during the use of the energy storage wire harness, improving the stability of power transmission and signal transmission, and ensuring the stable operation of the energy storage device. Two T-shaped blocks are respectively inserted into two notches, and the connection terminal is inserted into the connection slot to complete the connection between the wire harness body and the connector. Rotating the rotating ring causes the T-shaped block to move out of the notch and into the T-shaped annular groove. When the limiting block rotates to the vicinity of the notch, the elastic force of the helical spring causes the limiting block to insert into the notch, thus restricting the rotation of the rotating ring. At the same time, the T-shaped annular groove and the T-shaped block hook and fix the fixing ring, thus fixing the wire harness body and preventing the connection between the wire harness body and the connector from becoming loose.

[0013] 2. By setting a movable ring, this utility model can simultaneously pull two sliding rods, so that the two limiting blocks can be moved out of the two notches at the same time, which facilitates the disassembly of the wire harness body and the connector.

[0014] 3. This utility model achieves a sealing effect on the inside of the connection slot by setting a step, a sealing ring, and a fixing ring. When the connection terminal is inserted into the connection slot and connected to the connector, the sealing ring is inserted into the step. At the same time, the fixing plate limits and compresses the sealing ring, and the sealing ring seals the gap between the connection slot and the connection terminal, thereby sealing the inside of the connection slot and improving the waterproof performance.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0021] like Figures 1-4As shown, this utility model proposes an anti-loosening energy storage harness, including a harness body 1, a rotating ring 2, and a connector 3. A connection slot 17 is provided on one side of the outer surface of the connector 3. A connection terminal 4 is connected to one end of the harness body 1, and the connection terminal 4 is located inside the connection slot 17. The connection terminal 4 is inserted into the connection slot 17, connecting the harness body 1 and the connector 3. The harness body 1 is connected to the energy storage device through the connector 3, and the energy storage device transmits power and signals through the harness body 1. A T-shaped annular groove 15 is provided on the outer surface of the connector 3 near the connection slot 17. The cross-section of the T-shaped annular groove 15 is T-shaped. Notches 16 are provided on the inner wall of the T-shaped annular groove 15 near the front and rear surfaces of the connector 3. The harness body 1 passes through the rotating ring 2. A limit ring 7 is installed on the outer surface of the harness body 1 near the inner side of the rotating ring 2. A limit ring 7 is installed on the inner side of the rotating ring 2 near the upper and lower surfaces. T-shaped blocks 9 are fixedly connected to the surface positions via connecting rods 8. The two T-shaped blocks 9 can rotate into the T-shaped annular grooves 15 from the two notches 16 positions respectively. Through holes 11 are provided on the outer side of the rotating ring 2 near the front and rear surfaces. Slide rods 12 are inserted into the two through holes 11. Limiting blocks 14 are connected to the ends of the two slide rods 12 near the connector 3. Helical springs 13 are wound around the outer surfaces of the two slide rods 12. The helical springs 13 are located between the rotating ring 2 and the limiting blocks 14. A moving ring 10 is provided on the outer side of the rotating ring 2, and the ends of the two slide rods 12 are connected to the inner side of the moving ring 10. The inner diameter of the moving ring 10 is larger than the outer diameter of the wire harness body 1. The wire harness body 1 passes through the inside of the moving ring 10. The two slide rods 12 are pulled by the moving ring 10 at the same time, so that the two limiting blocks 14 are moved out from the two notches 16 at the same time, which facilitates the disassembly of the wire harness body 1 and the connector 3.

[0022] In use, the two T-shaped blocks 9 are inserted into the two notches 16 respectively, and the connecting terminal 4 is inserted into the connecting slot 17 to connect the wire harness body 1 and the connector 3. Rotating the rotating ring 2 causes the T-shaped blocks 9 to move out of the notches 16 and into the T-shaped annular groove 15. When the limiting block 14 rotates to the vicinity of the notch 16, the elastic force of the helical spring 13 causes the limiting block 14 to insert into the notch 16, thus restricting the rotation of the rotating ring 2. At the same time, the fixing ring 2 is hooked and fixed by the T-shaped annular groove 15 and the T-shaped blocks 9, which also fixes the wire harness body 1, preventing the connection between the wire harness body 1 and the connector 3 from becoming loose. This improves the stability of power transmission and signal transmission and ensures the stable operation of the energy storage device. Example 2

Compared with the first embodiment, this embodiment also includes a step 18 provided on the outer surface of the connector 3 near the edge of the connecting slot 17, a sealing ring 5 sleeved on the outer surface of the connecting terminal 4, and the sealing ring 5 is located inside the step 18. A fixing ring 6 is sleeved on the outer surface of the connecting terminal 4 near the outer side of the sealing ring 5.

[0024] In this embodiment, after the connecting terminal 4 is inserted into the connecting slot 17 and connected to the connector 3, the sealing ring 5 is inserted into the step 18. At the same time, the fixing plate 6 limits and compresses the sealing ring 5, and the sealing ring 5 seals the gap between the connecting slot 17 and the connecting terminal 4, thereby sealing the inside of the connecting slot 17 and improving the waterproof performance.
