Description
Technical field
The present invention relates to a kind of power battery pack syndeton, is the power battery pack flexible connecting structure of a kind of big electric current vibration proof and impact specifically.
Background technology
At present, automobile power cell need be with obtaining needed output voltage and electric current after a plurality of battery unit connection in series-parallel owing to the restriction of capacity.What adopt in the industry all is to make conductor with copper bar, and mounting means is the mode that adopts bolt to tighten.The problem that this mode exists has: 1, the contact resistance of battery and copper bar is influenced by the bolt coupling mechanism force, in case bolt gets loose because of vibration in the automobile driving process, this contact resistance will double or approach infinity so; In a single day contact resistance increases severely, and the temperature of battery unit will rise, and finally causes battery failure even burning.This is a very serious potential safety hazard.2, because the connection of the copper bar between the battery unit is a rigidity, vibration in the automobile driving process and impact are easy to cause bolt looseness.3, extremely inconvenience is safeguarded in dismounting.Adopt this packaged type, whether automobile must lock by each bolt of scrutiny when maintenance.
Summary of the invention
The power battery pack flexible connecting structure that the purpose of this invention is to provide a kind of big electric current vibration proof and impact.
The object of the invention is realized through following technical scheme.
A kind of power battery pack syndeton; It is characterized in that: said power battery pack syndeton comprises output contact pin, copper strips, copper sheathing, copper ring and the connector that is arranged on the electrokinetic cell unit; Connector is installed on the copper sheathing through copper ring; Copper sheathing is sleeved on the copper strips, and the output contact pin is inserted in the connector.
Said connector is for changeing the spring connector.
Said copper ring is for reinforcing copper ring, and connector is reinforced through copper ring and is installed on the copper sheathing.
Said copper strips is the braiding copper strips.
Said copper sheathing is provided with another output contact pin.
The present invention compared with prior art has the following advantages:
Battery unit of the present invention only need be reserved two contact pins for its output in encapsulation, combine to realize required connection in series-parallel through changeing the spring connector with the braiding copper strips.Its characteristics are following: 1, abandon the great bolt of potential safety hazard fully and connect, adopt the circular spring connector that changes to replace with braiding copper.This commentaries on classics spring connector is owing to structural characteristics, and after the process vibration and shock testing, its contact resistance still can keep minimum scope (below 0.1 milliohm).2, the connection between the battery unit is elasticity and flexibly connects, and satisfies the requirement of automobile to component vibration and impact fully.3, dismounting, maintenance are very convenient, efficient.Adopt the connected mode of this structure, only need to change spring connector insertion battery output contact pin during installation and get final product, directly extract during dismounting, and Maintenance free.

Embodiment
Below in conjunction with accompanying drawing power battery pack syndeton of the present invention is described in further detail.
Like Fig. 1 to Fig. 5; Power battery pack syndeton of the present invention comprises output contact pin 2, copper strips 3, copper sheathing 4, the copper ring 5 and connector 6 that is arranged on the electrokinetic cell unit 1; Connector is installed on the copper sheathing through copper ring, and copper sheathing is sleeved on the copper strips, and the output contact pin is inserted in the connector.Connector is for changeing the spring connector.Copper ring is for reinforcing copper ring, and connector is reinforced through copper ring and is installed on the copper sheathing.Copper strips is the braiding copper strips.Copper sheathing is provided with another output contact pin 7.
Battery unit of the present invention only need be reserved two contact pins for its output in encapsulation, combine to realize required connection in series-parallel through changeing the spring connector with the braiding copper strips.Its characteristics are following: 1, abandon the great bolt of potential safety hazard fully and connect, adopt the circular spring connector that changes to replace with the braiding copper strips.This commentaries on classics spring connector is owing to structural characteristics, and after the process vibration and shock testing, its contact resistance still can keep minimum scope (below 0.1 milliohm).2, the connection between the battery unit is elasticity and flexibly connects, and satisfies the requirement of automobile to component vibration and impact fully.3, dismounting, maintenance are very convenient, efficient.Adopt the connected mode of this structure, only need to change spring connector insertion battery output contact pin during installation and get final product, directly extract during dismounting, and Maintenance free.
