Temperature sensor is widely used in automobile industry, by the variation of thermistor, to monitor the variation of output voltage or electric current, from
And realize the monitoring to temperature.Temperature acquisition harness is made of materials such as conducting wire, terminal, connector and sheaths, by temperature control
The electronic signal and data-signal of system are transmitted and are exchanged, and are the conduction minds of power battery pack monitoring temperature and information collection
It is the critical component for guaranteeing the safety and reliability of battery system.
Existing temperature acquisition harness is using " set loop wire nose-gathering line-acquisition plug " integrated configuration: set loop wire nose
Son is tightened on busbar connector and battery core pole with bolt, using pyrocondensation protection of pipe.Strand design is acquired according to battery pack mould
On the basis of group PACK body structure, the distribution of cabinet inner module group, mould group self structure and collection point arrangement, so early period needs
A large amount of wire length estimations and statistical work are done, the energy of staff is not only consumed but also is very easy to error.Its set loop wire simultaneously
Nose is bolted on battery core pole, when being pullled by external force, is easy to produce between gathering line and set loop wire nose
Fracture.And acquisition harness step when producing line is assembled is also very complicated complexity, is easy error, so assembly efficiency is low,
It is not easily accomplished automation.
Utility model content
The applicant is provided and a kind of structurally reasonable is applied to power battery for the disadvantage in above-mentioned existing production technology
