The failure of battery.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of good heat dissipation effect, resistance to
The lithium ion battery of the axial lead of vibration.
In order to solve the above technical problems, the utility model proposes technical solution are as follows: a kind of lithium-ion electric of axial lead
Pond, including shell and battery core, the battery core are sealingly disposed in shell, and the battery core is wound by anode, diaphragm and cathode,
The both ends of the battery core are respectively arranged with anode collection disk and negative pole currect collecting disk, the anode and cathode respectively with anode collection disk
It is connected with negative pole currect collecting disk, positive outside wire is respectively arranged on the anode collection disk and negative pole currect collecting disk and cathode is drawn
Line, the positive outside wire and negative outside wire are drawn at the both ends of shell respectively.In the present invention, positive outside wire and
Negative outside wire is drawn at the both ends of shell respectively, in this way by the lithium ion battery of the utility model install assist side or its
When on his position, lithium ion battery is laid across, low compared to vertically-mounted form center of gravity, and vibration strength is more preferable.
The lithium ion battery of above-mentioned axial lead, it is preferred that a side 0.5-3mm of the anode in diaphragm, institute
State cathode and stretch out 0.5-3mm in another side of diaphragm, the anode collection disk and negative pole currect collecting disk squeezes respectively stretch out every
The anode and cathode of film side.In the present invention, anode can be squeezed using anode collection disk and negative pole currect collecting disk respectively
Connection type with cathode is to draw anode and cathode, and this type of attachment is without anode compared with traditional type of attachment
To the connecting line between current collecting plates, also just without the welding between connecting line and current collecting plates.In the case of vibrations, this to squeeze
Crimping touch type of attachment is more secured, and there is no the welding between conventional lithium ion battery connecting line and current collecting plates to point out
The phenomenon that now loosening.
The lithium ion battery of above-mentioned axial lead, it is preferred that the outside of the anode collection disk and negative pole currect collecting disk is equal
It is provided with one piece of rubber pad, the both ends of the shell are respectively arranged with positioning and girdle the waist, the anode collection disk and negative pole currect collecting disk
It is separately positioned on and positions on a tight waist, pass through crimping and positioning extruding sealing with a tight waist between the shell and rubber pad.Positioning is with a tight waist
It has just been completely fixed the position of current collecting plates and rubber pad with the setting of crimping, provides guarantee for the airtightness of lithium ion battery, together
When make battery core not and will receive the excessive extruding of current collecting plates, and cause the unstable of electrical property.In the present invention, crimping
It is the same for being arranged with the seal bead of aluminium electrolutic capacitor.
The lithium ion battery of above-mentioned axial lead, it is preferred that it is provided with to fix in the middle part of the shell and girdle the waist, it is described solid
It is fixed with a tight waist in circle shape, vertical bar shape or dotted.Battery core can be immobilized in the shell by fixed setting with a tight waist, while fixing bundle
Waist is due to touching battery core, and when battery core fever, heat can run through fixed girdle the waist and be transmitted to outside, to complete
Heat dissipation, so that the perfect heat-dissipating of the lithium ion battery of the utility model.
The lithium ion battery of above-mentioned axial lead, it is preferred that the fixation positioning with a tight waist than shell both ends is girdled the waist
Depth is big.
Compared with the prior art, the advantages of the utility model are: the lithium ion battery of the axial lead of the utility model
Vibration strength it is good, and good heat dissipation effect.
