Description

Technical Field

[0001] The utility model relates to the field of electronic wire harnesses, in particular to a voltage and temperature acquisition wire harness. Background Art

[0002] The rapid development of new energy, especially electric vehicles and energy storage systems, requires precise monitoring of battery packs to ensure safety and efficiency. The battery management system (BMS) monitors the voltage and temperature of each unit in real time through the voltage and temperature acquisition harness to ensure that it works in the best condition. With the advancement of technology, these harnesses need to have high performance, such as high temperature resistance, good electrical conductivity, and reliability in harsh environments. However, since these harnesses usually contain three or more wires, they are prone to entanglement during the actual layout process, which may not only increase the contact resistance between the wires, but also cause local overheating. In extreme cases, it may even cause the harness to melt or burn, bringing safety risks that cannot be ignored. For this reason, we propose a voltage and temperature acquisition harness.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A voltage and temperature collection harness comprises three groups of voltage and temperature collection wires 1, both ends of the three groups of voltage and temperature collection wires 1 are fixedly provided with power terminals 2, the three groups of voltage and temperature collection wires 1 are sleeved with a sleeve plate 3, one side of the sleeve plate 3 is fixedly provided with a first blocking plate 5, the first blocking plate 5 is provided with a positioning block 7, the sleeve plate 3 is provided with an extension plate 4, and further comprises:

[0025] An adjustment assembly, which is mounted on the extension plate 4 and is used to adjust wire harnesses of different lengths;

[0026] The limit assembly is located on the positioning block 7 and is used to fix different wiring harnesses after adjustment.

[0027] Two groups of first blocking plates 5 are provided, which are respectively installed between two adjacent groups of voltage and temperature acquisition lines 1. The two groups of first blocking plates 5 and the two groups of second blocking plates 6 form a barrier for the three groups of voltage and temperature acquisition lines 1 to prevent the groups of voltage and temperature acquisition lines 1 from being attached to each other.

[0028] Positioning blocks 7 are fixedly provided on one side of the two groups of first blocking plates 5 and at the end positions away from the sleeve plate 3 . The positioning blocks 7 slide in the transverse grooves 10 to prevent the first blocking plates 5 from being separated from the second blocking plates 6 .

[0029] The adjustment component includes a second blocking plate 6, a transverse groove 10, a side plate 11 and holes 12. Two groups of second blocking plates 6 are fixedly provided on one side of the extension plate 4 corresponding to the sleeve plate 3. A horizontal transverse groove 10 is provided on one side of the second blocking plate 6. A side plate 11 is fixedly provided on one side of the second blocking plate 6 corresponding to the transverse groove 10, and a plurality of groups of holes 12 equidistantly distributed are provided on the side plate 11. At the same time, the positioning block 7 slides in the transverse groove 10 as the second blocking plate 6 moves, and the three groups of voltage and temperature acquisition lines 1 gradually become straight lines as the second blocking plate 6 slides.

[0030] The two groups of first blocking plates 5 are respectively slidably connected to the inner wall of the second blocking plate 6, and then the extension plate 4 is pulled on the three groups of voltage and temperature collection lines 1. During the sliding process of the extension plate 4 on the three groups of voltage and temperature collection lines 1, the second blocking plate 6 is synchronously driven to slide synchronously on the first blocking plate 5.

[0031] The limiting assembly includes a vertical rod 8 and a steel ball 9. The positioning block 7 is slidably connected to a vertical vertical rod 8. The bottom end of the vertical rod 8 extends beyond the bottom of the positioning block 7. A steel ball 9 is fixed to the outer wall of the vertical rod 8 corresponding to the position near the top. When the length is determined, the vertical rod 8 is pressed downward to make the vertical rod 8 slide downward on the positioning block 7, and the positioning block 7 is inserted into the hole 12 to fix the position of the extension plate 4 on the voltage and temperature acquisition line 1. The steel ball 9 prevents the top of the vertical rod 8 from sliding out of the positioning block 7.

[0032] The positioning block 7 is slidably engaged in the horizontal groove 10, and the bottom of the vertical rod 8 is movably inserted into one of the groups of holes 12. When the three groups of voltage and temperature acquisition lines 1 need to be straightened to prevent the three groups from causing safety hazards due to high temperature bonding, the vertical rod 8 is pulled up on the positioning block 7 to make the vertical rod 8 disengage from the hole 12. The first blocking plate 5 and the second blocking plate 6 are arranged between two adjacent groups of voltage and temperature acquisition lines 1, which effectively prevents each group of voltage and temperature acquisition lines 1 from causing safety hazards due to high temperature during long-term operation, protects the safety of the device and extends the service life of the voltage and temperature acquisition line 1. In addition, by inserting the vertical rod 8 into the hole 12 on the side plate 11, the position of the first blocking plate 5 and the second blocking plate 6 can be effectively fixed after the voltage and temperature acquisition lines 1 of different lengths are adjusted, preventing the three groups of voltage and temperature acquisition lines 1 from being entangled when the voltage and temperature acquisition lines 1 are moved, thereby solving the problem that the three groups of voltage and temperature acquisition lines 1 need to be straightened by the operator when they are entangled.

[0033] Working principle: when it is necessary to straighten the three groups of voltage and temperature acquisition lines 1 to prevent safety hazards caused by high-temperature adhesion, pull up the vertical rod 8 on the positioning block 7 to make the vertical rod 8 disengage from the hole 12, and then pull the extension plate 4 on the three groups of voltage and temperature acquisition lines 1. During the sliding process of the extension plate 4 on the three groups of voltage and temperature acquisition lines 1, the second blocking plate 6 is synchronously driven to slide on the first blocking plate 5. At the same time, the positioning block 7 slides in the transverse groove 10 with the movement of the second blocking plate 6. The three groups of voltage and temperature acquisition lines 1 gradually become a straight line state with the sliding of the second blocking plate 6, and the two groups of first blocking plates 5 and the two groups of second blocking plates 6 form a barrier for the three groups of voltage and temperature acquisition lines 1 to prevent the groups of voltage and temperature acquisition lines 1 from being adhered to each other. When the length is determined, press the vertical rod 8 downward to make the vertical rod 8 slide downward on the positioning block 7, and use the positioning block 7 to be inserted into the hole 12 to fix the position of the extension plate 4 on the voltage and temperature acquisition line 1.
