Abstract
The invention discloses a kind of connection structure of power battery pack, it is characterized in that: described connection structure of power battery pack comprises the output contact pin, copper strips, copper sheathing, copper ring and the connector that are arranged on electrokinetic cell unit, connector is arranged on copper sheathing by copper ring, copper sheathing is sleeved on copper strips, exports contact pin and is inserted in connector.Described connector is for turning spring connector.Described copper ring is for reinforcing copper ring, and connector is reinforced by copper ring and is arranged on copper sheathing.Described copper strips is braiding copper strips.Described copper sheathing is provided with another and exports contact pin.The present invention has the advantage of vibration proof and impact.
Description
Technical field
The present invention relates to a kind of connection structure of power battery pack, is the power battery pack flexible connecting structure of a kind of big current vibration proof and impact specifically.
Background technology
At present, automobile power cell, owing to holding quantitative limitation, needs to obtain required output voltage and electric current with after multiple battery unit connection in series-parallel.What adopt in the industry is all make conductor with copper bar, and mounting means is the mode adopting bolt tightening.This mode Problems existing has: 1, the contact resistance of battery and copper bar affects by bolt-locking power, once bolt gets loose because vibrating in automobile driving process, so this contact resistance will double or approach infinity; Contact resistance is once increase severely, and the temperature of battery unit will rise, and finally causes battery failure even to burn.This is a very serious potential safety hazard.2, because the copper bar connection between battery unit is rigidity, the vibration in automobile driving process and impact are easy to cause bolt looseness.3, extremely inconvenience is safeguarded in dismounting.Adopt this packaged type, automobile must carefully check whether each bolt locks when maintaining.
Summary of the invention
The object of this invention is to provide the power battery pack flexible connecting structure of a kind of big current vibration proof and impact.
Object of the present invention is achieved through the following technical solutions.
A kind of connection structure of power battery pack, it is characterized in that: described connection structure of power battery pack comprises the output contact pin, copper strips, copper sheathing, copper ring and the connector that are arranged on electrokinetic cell unit, connector is arranged on copper sheathing by copper ring, copper sheathing is sleeved on copper strips, exports contact pin and is inserted in connector.
Described connector is for turning spring connector.
Described copper ring is for reinforcing copper ring, and connector is reinforced by copper ring and is arranged on copper sheathing.
Described copper strips is braiding copper strips.
Described copper sheathing is provided with another and exports contact pin.
The present invention compared with prior art has the following advantages:
Battery unit of the present invention only needs for it exports reserved two contact pins when encapsulation, combine the connection in series-parallel needed for realizing by turning spring connector and weaving copper strips.Its feature is as follows: 1, abandon the great bolt of potential safety hazard completely and connect, and adopts circle to turn spring connector and replaces with braiding copper.This spring connector that turns is due to structural feature, and after vibration and shock testing, its contact resistance still can keep minimum scope (below 0.1 milliohm).2, the connection between battery unit is elasticity and flexibly connects, and meets the requirement of automobile to component vibration and impact completely.3, dismounting, maintenance are very convenient, efficient.Adopt the connected mode of this structure, only need insert battery output contact pin by turning spring connector during installation, directly extracting during dismounting, and Maintenance free.
Accompanying drawing explanation

Fig. 2 is the structural representation of electrokinetic cell unit of the present invention;
Fig. 3 is the structural representation () of connection structure of power battery pack of the present invention;
Fig. 4 is the structural representation (two) of connection structure of power battery pack of the present invention;
Fig. 5 is the structural representation that copper sheathing in connection structure of power battery pack of the present invention is arranged on copper strips.
Embodiment
Below in conjunction with accompanying drawing, connection structure of power battery pack of the present invention is described in further detail.
As Fig. 1 to Fig. 5, connection structure of power battery pack of the present invention comprises the output contact pin 2 be arranged on electrokinetic cell unit 1, copper strips 3, copper sheathing 4, copper ring 5 and connector 6, connector is arranged on copper sheathing by copper ring, and copper sheathing is sleeved on copper strips, exports contact pin and is inserted in connector.Connector is for turning spring connector.Copper ring is for reinforcing copper ring, and connector is reinforced by copper ring and is arranged on copper sheathing.Copper strips is braiding copper strips.Copper sheathing is provided with another and exports contact pin 7.
Battery unit of the present invention only needs for it exports reserved two contact pins when encapsulation, combine the connection in series-parallel needed for realizing by turning spring connector and weaving copper strips.Its feature is as follows: 1, abandon the great bolt of potential safety hazard completely and connect, and adopts circle to turn spring connector and replaces with braiding copper strips.This spring connector that turns is due to structural feature, and after vibration and shock testing, its contact resistance still can keep minimum scope (below 0.1 milliohm).2, the connection between battery unit is elasticity and flexibly connects, and meets the requirement of automobile to component vibration and impact completely.3, dismounting, maintenance are very convenient, efficient.Adopt the connected mode of this structure, only need insert battery output contact pin by turning spring connector during installation, directly extracting during dismounting, and Maintenance free.
