Background technique
Lead storage battery is mainly made of electrolyte, battery case and pole group, and the electrolyte of lead storage battery is sulfuric acid solution,
Middle pole group is mainly made of positive plate, negative plate and partition, and partition primarily serves storage electrolyte, the gas compound as oxygen
Channel, play prevent active material fall off and positive and negative electrode between short-circuit effect.There is busbar connector and lead to pass a bridge on the group of pole will
All pole groups are together in series, and the upper connecting pin pole of pole group at both ends, end pole passes through the pole column hole in battery case slot cover, as
Positive and negative output end (input terminal).
Lead-acid accumulator needs all positive plates by each pole group to be connected to by busbar connector in assembling production process
Together, all negative plates of each pole group are linked together by busbar connector, then are connected by the way that the pole on busbar connector is positive and negative,
Reach several single lattice pole group series connection and forms single battery.
Busbar connector generally comprises the connecting bridge with tab welding, and the pole being fixed in connecting bridge, existing busbar connector
Connecting bridge sectional area is identical everywhere, but when working, the electric current on all pole plates can be pooled at pole, cause to connect in this way
Connect that bridge portion of electrical current at pole is big, and the portion of electrical current far from pole is small, so that the structure with connecting bridge is incompatible, wave
Take material, increases production cost.
Authorization Notice No. is that the Chinese utility model patent of CN202103113U discloses a kind of storage battery busbar, by even
Connect bridge and be fixed in connecting bridge pole composition, the connecting bridge from both ends end to the junction cross-sectional area with pole by
Cumulative big, the connecting bridge is gradually increased from both ends end to the junction height with pole, and width remains unchanged.
Authorization Notice No. is that the Chinese utility model patent of CN203617381U discloses a kind of novel storage battery busbar,
Including busbar connector ontology and the terminal being connected on busbar connector ontology, the busbar connector ontology is from separate terminal to close to terminal
Place's cross-sectional area becomes larger.
Above-mentioned two in the prior art by being designed to busbar connector from separate terminal to close to cross-sectional area at terminal
Become larger, but cross section be it is rectangular, square structure is easy to happen bending, and especially one end cross-sectional area is smaller；Busbar connector
It is peripherally homogeneous corrosion by acid corrosion, square cross section circumferential direction local corrosion is too fast, causes the too early life termination of busbar connector.
Utility model content
The utility model is directed to the deficiencies in the prior art, provides a kind of storage battery busbar and battery.
A kind of storage battery busbar, including busbar connector ontology and the pole being connected on busbar connector ontology, the busbar connector
The cross-sectional shape of ontology is semicircle or half elliptic.
The cross-sectional area of the busbar connector ontology is gradually increased from pole distal end to pole proximal end.The pole, which is located at, to converge
One end of stream row's ontology, the cross-sectional area of the pole distal end of busbar connector ontology and the cross-sectional area ratio of pole proximal end are 1:
1.2~1.5.When due to work, the electric current on all pole plates can be pooled at pole, cause the pole of busbar connector ontology close in this way
Hold electric current big, and pole distal end electric current is small, design in this way can make the structure of busbar connector more reasonable, without excess stock wave
Take, makes full use of the material of entire busbar connector.
The pole distal end of the busbar connector ontology is 1/4 spherical shape.Design is in this way convenient for demoulding.
The utility model additionally provides the battery comprising the storage battery busbar, and the battery includes pole group, institute
Stating pole group includes spaced several positive plates and negative plate, and the anode ear of all positive plates is arranged in a row and positive bus
Welding, the negative electrode lug of all negative plates is arranged in a row to be welded with negative bus-bar.
The battery, pole distal end covering tab 1~2mm of top of busbar connector ontology.The battery, confluence
Arrange 4~6mm at the top of the pole proximal end covering tab of ontology.When work, the electric current on all pole plates can be pooled at pole, in this way
Cause the pole proximal end electric current of busbar connector ontology big, and pole distal end electric current is small, the pole proximal end of busbar connector ontology covers tab
Covering tab in more and pole distal end is less, can optimize confluence effect in this way.
The utility model storage battery busbar is by being designed to that semicircle or half is ellipse for the cross-sectional shape of busbar connector ontology
Circle is analyzed from amechanical angle, preferably busbar connector can be avoided to be bent than other squared designs or trapezoidal design, from corrosion angle
Degree analysis, because busbar connector is peripherally uniformly to corrode to depths by acid corrosion, using the design of semicircle or half elliptic
, can be uneven to avoid corrosion ratio everywhere for square cross section, the too fast corrosion of local location causes busbar connector too early
Life termination.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model busbar connector.
Fig. 2 is the pole group structure schematic diagram with the utility model busbar connector.
