According to the leading-out structure, a negative electrode electric conduction handle of a battery core and a negative electrode column on the shell are riveted together by a riveting device through the pulling rivet, or a positive electrode electric conduction handle of the battery core and a positive electrode column on the shell are riveted together by the riveting device through the pulling rivet, the connection is firm, the internal resistance is small, and the guarantee is provided for a heavy-current path, thus the requirements of high-capacity power batteries and high-power power batteries on drainage are satisfied.
Description
[technical field]
The present invention relates to deriving structure and the outbound course of battery conductive handle.
[background technology]
Positive and negative plate is the core of battery, and the processing of positive and negative plate also is that battery is made most important manufacturing step in the link.Pole piece is divided into positive plate and negative plate, and the lug on the pole piece is the leading-out end of positive and negative electrode, the function of being responsible for switching on by lug.
At present the outbound course of general cylindrical battery conduction handle is: negative pole end directly with electric resistance welding from electric core centre bore insert capillary negative pole conduction handle and shell at the bottom of or at the bottom of the shell conduction pole of center predetermined fixed weld.Positive terminal welds by ultrasonic wave or laser and cover assembly by the lug that welds in advance on the electric core.
Oneself can not satisfy high power capacity electrokinetic cell or high power electrokinetic cell for the needs of drainage the way of this routine.At first if the electric core of negative pole end is under highly bigger situation, capillary just require long, capillary grown the welding just relatively poor.Electric resistance welding is also reliable to its first solder joint in addition, and other point reliability just dying.An apparent and visible solder joint will be impossible by very big electric current.Secondly positive terminal will be communicated with electric core and anode end cap by lug, if the too short bad operation of lug, if oversize, this lug has just become the bottleneck on the big current path.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, propose a kind of battery conductive handle deriving structure, can be connected firmly, internal resistance is little, for big current path provides safeguard, thereby satisfy high power capacity electrokinetic cell and high power electrokinetic cell for the needs of drainage.
For achieving the above object, the utility model proposes a kind of battery conductive handle deriving structure, comprise volume core, conflux disk, leading-out terminal, shell and pulling rivet, described volume core and conflux disk all are arranged on the inside of shell, the end of volume core is connected with conflux disk, described leading-out terminal is fastened on the shell, adopts the fixing riveted joint locking of pulling rivet between described conflux disk and the leading-out terminal.
As preferably, described pulling rivet is positioned at the center of conflux disk, and the staking of conflux disk and terminal is connected can also can be at any position of battery in the centre.
As preferably, described pulling rivet forms a semi-round ball in inside, and pulling rivet can be that to remain silent also can be opening, can be that countersunk head also can be tack, and all can play pulling rivets such as locking leading-out terminal and conflux disk and all belong to this scope.
As preferably, described leading-out terminal is provided with annular protrusion, and annular protrusion is close on the inner surface of shell.
As preferably, the centre of described conflux disk is provided with the platform to outer lug, and this raised platforms not only is applicable to circular batteries, is applicable to rectangular cell too.
The beneficial effects of the utility model: the utility model utilizes the method for staking, directly the negative pole pole on electric core negative pole conduction handle and the shell is riveted by pulling rivet with staking equipment, also can directly the Positive Poles on electric core anodal conduction handle and the shell be riveted by pulling rivet with staking equipment, be connected firmly, internal resistance is little, for big current path provides safeguard, thereby satisfy high power capacity electrokinetic cell and high power electrokinetic cell for the needs of drainage.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
