Abstract
The utility model discloses a current collector copper needle of alkaline manganese cell negative pole, include with the battery negative pole at the bottom of looks welded protruding position and the needle body that links to each other with protruding position, the external diameter of protruding position is 2.0-2.3mm, the diameter of needle body is 1.1-1.3mm, the total height 20-25mm of copper needle. The needle body is divided into two parts, the front end part is inserted into the battery negative paste, and the rear end part close to the raised part is inserted into the battery sealing ring. The utility model discloses the copper needle diameter reduces before comparing, and copper needle weight is little, and the copper needle volume also reduces simultaneously, is favorable to controlling the negative pole cream plane height of battery, increases the air chamber, reduces the inside atmospheric pressure of battery to the weeping proportion of battery has been reduced.
Description
Technical Field
The utility model relates to an alkaline manganese cell, in particular to alkaline manganese cell negative pole mass flow body copper needle.
Background
At present, alkaline zinc-manganese batteries LR6 and LR03 both adopt negative current collector copper needles with the diameter of 1.4-1.5mm, and the diameter of the negative current collector copper needles is larger, so that the negative paste plane is higher, the air chamber is smaller, the air pressure in the battery is in a higher state, the battery leakage is easily caused, the performance of the battery is influenced, and the safety is not high.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defect that above-mentioned prior art exists, the utility model provides an alkaline manganese cell negative pole mass flow body copper needle, reducible copper needle weight reduces battery manufacturing cost, and the copper needle volume also reduces simultaneously, is favorable to controlling the negative pole cream plane height of battery, increases the air chamber, reduces the inside atmospheric pressure of battery to the weeping proportion of battery has been reduced.
In order to realize the purpose, the technical scheme of the utility model is as follows:
the alkaline manganese battery negative pole mass flow body copper needle includes the protruding position and the needle body that links to each other with protruding position that looks welded at the bottom of the battery negative pole, the external diameter of protruding position is 2.0-2.3mm, the diameter of needle body is 1.1-1.3mm, and the total height of copper needle is 20-25mm.
Furthermore, the needle body is divided into two parts, the front end part of the needle body is inserted into the battery negative paste, the rear end part of the needle body close to the protruding part is inserted into the battery sealing ring, so that the plane height of the battery negative paste is convenient to control, and the rear end part is used as a sealing part of the sealing ring, so that sealing is tight.
The beneficial effects of the utility model are that, the negative pole mass flow body copper needle diameter before comparing reduces, and the volume also correspondingly reduces, has effectively reduced manufacturing cost to be favorable to controlling the negative pole cream plane height of battery, increase the air chamber, reduce the inside atmospheric pressure of battery, thereby reduced the effect of the weeping proportion of battery.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
in order to make the creation features, technical means and achievement objects of the present invention easily understood and appreciated, the present invention will be further described with reference to the following embodiments.
Example (b):
referring to fig. 1, the alkaline manganese cell negative current collector copper needle comprises a convex part 2 and a connected needle body, wherein the needle body is divided into a front end part 1 and a rear end part 3;
the outer diameter of the convex part 2 is designed to be 2.1mm and is welded with the negative electrode bottom of the battery;
the front end part 1 is inserted into a paste part of a battery cathode, and the rear end part 3 is inserted into a sealing ring of the battery to be used as a sealing part;
the front end portion 1 and the rear end portion 3 constitute a needle body of a copper needle, the outer diameter thereof is set to 1.1mm, and the total height of the copper needle is 22mm.
The LR6 battery is made according to alkaline manganese cell production technology to this alkaline manganese cell negative pole mass flow body copper needle spot welding equipment, does not use usually the battery of copper needle, after 70 ℃ stores, the weeping phenomenon just begins to appear in succession after 30 days, and the improvement battery just begins to appear in succession after 45 days weeping phenomenon.
By adopting the copper needle with the structure, the weight of the copper needle can be reduced, the production cost of the battery can be reduced, meanwhile, the volume of the copper needle is also reduced, the control of the plane height of the negative paste of the battery is facilitated, the air chamber is increased, the air pressure in the battery is reduced, and therefore, the leakage proportion of the battery is reduced.
The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
