Description

Technical Field

[0001] The utility model relates to the technical field of energy storage battery wiring harnesses, in particular to an energy storage battery wiring harness with a compression-resistant structure. Background Art

[0002] The energy storage battery wiring harness is an important component that connects various components in the energy storage battery system. Its main functions include transmitting current, signals, and achieving stable operation and efficient management of the battery system. The energy storage battery wiring harness is an indispensable part of the energy storage battery system. Its quality and performance directly affect the operation effect and safety of the entire battery system.

[0003] During the operation of existing energy storage batteries, the wiring harness may be squeezed or impacted by the battery or other components, so the energy storage battery wiring harness needs to have good pressure resistance. If the pressure resistance of the wiring harness is poor, it may cause problems such as conductor breakage and insulation damage inside the wiring harness, thereby affecting the normal transmission of electric energy and the stable operation of the battery system.

[0004] For example, a wiring harness for a new energy vehicle charging pile disclosed with announcement number CN207530200U does not have a pressure-resistant protection structure on the outside of the wiring harness in the patent, so that when the wiring harness is squeezed by external force, it can only rely on itself for pressure protection, and the insulating sleeve wrapped on the wiring harness cannot play a buffering and protective role. Therefore, the wiring harness is not able to withstand external forces, which makes the wiring harness prone to squeezing, bending, damage and breakage when subjected to external pressure, which not only reduces the service life of the wiring harness, but also easily causes certain safety hazards.

[0005] Therefore, it is necessary to invent an energy storage battery wiring harness with a compression-resistant structure to solve the above problems. Utility Model Content

[0026] The No. 1 limit seat 3 is fixedly connected to the wall of the battery body 1, and the No. 2 limit seat 4 is slidably connected to the wall of the battery body 1. The No. 1 limit seat 3 is arranged directly above the No. 2 limit seat 4. There are two adjusting screws 6 and hand nuts 7. The two adjusting screws 6 are threadedly connected to the hand nuts 7. The outer wall threads of the adjusting screws 6 match the inner wall threads of the hand nuts 7. A slider 8 is fixedly installed on the side of the No. 2 limit seat 4 close to the battery body 1. A slide groove 9 is provided at the contact position between the slider 8 and the battery body 1. The slider 8 and the slide groove 9 are slidably connected.

The protective pad 10 is a silicone pad, and the protective pad 10 is fixed to the No. 1 limit seat 3 and the No. 2 limit seat 4 by adhesive bonding.

[0027] The No. 1 limit seat 3 is installed on the battery body 1 by a fixed connection, ensuring the stable position of the wire harness body 2 at one end. This connection method makes it difficult for the wire harness to be displaced or fall off when subjected to external force or vibration, thereby ensuring the reliability of the connection between the battery and the wire harness, and the No. 2 limit seat 4 is connected by a sliding connection between the slider 8 and the slide groove 9, so that the No. 2 limit seat 4 can slide freely on the battery body 1, which is easy to adjust to adapt to wire harness bodies 2 of different sizes, and by rotating the hand-tightening nut 7, the distance between the No. 1 limit seat 3 and the No. 2 limit seat 4 can be fixed, ensuring that the No. 1 limit seat 3 and the No. 2 limit seat 4 stably clamp the wire harness body 2, and the protective pad 10 plays a role of buffering and protection, which reduces the risk of wear and damage to the wire harness body 2.
