Abstract

The disclosed battery includes body case and battery core. Electrolyte is filled into body case. Battery core is composed of multiple pieces of positive and negative plates and diaphragms stacked alternately. Not coated faces of positive and negative plates are arranged in reverse orientation. Not coated faces of positive and negative plates are binding connected by terminal bundles respectively. Apertures setup at two ends at front and back faces of case are in use for installing output sockets of positive and negative poles. Socket mounting holes perpendicular to pole plate are at two ends of bundles. Assemblies of elastic socket are installed inside socket mounting holes. The invention changes raised output terminals in traditional battery to socket type output as well as changes wire connection to bolt connection. Advantages are: good conductivity and invisibility. Bolt connection makes connected batteries stable without need of additional supporter.

[technical field]
What the present invention relates to is lithium ion battery, especially a kind of plug ducting type large capacity lithium ion battery.
[technical background]
At present, for increasing the charge storage ability of lithium ion battery, to prolong the discharge time of lithium ion battery, manufacturer has proposed much can improve the technical scheme of capacity of lithium ion battery, as Chinese patent CN1307376A " a kind of rechargeable Cr-F-Li solid electrokinetic cell ", CN2615878Y " but repeated charge large-capacity power lithium battery of architecture advances ", CN2615877Y " but high-voltage lithium ion batteries of repeated charge " etc., provide practicable technical scheme for making high capacity lithium ion battery, can see from disclosed patent documentation, existing high capacity lithium ion battery all adopts the multilayer positive/negative plate to stack structure, that is: the transmitted beam head with polylith just, negative plate and barrier film stack the back bookbinding and connect to form the lithium ion battery core body.The bundle head that is used for the pole plate bookbinding is provided with the positive pole output pole and the negative pole output pole of evagination.This class high capacity lithium ion battery contains the electric energy of high several times to tens times of general lithium ion battery, has prolonged its ability to work greatly, can satisfy the needs of the long-time output of electric energy, has solved the little defective of common lithium battery reserve of electricity.High capacity lithium ion battery is of wide application, and it can be used as the electrical source of power of main equipments such as automobile, steamer.In actual use, for satisfying the normal operation of a main equipment, need outfit tens even up to a hundred lithium ion batteries usually, the positive and negative terminals of each lithium ion battery need interconnect.For connecting conducting between convenient positive and negative terminals with each lithium ion battery, all be provided with screw thread mouth on the raised type pole of existing lithium ion battery, and being equipped with the lead that is used for connecting between positive and negative terminals, the two ends of lead are respectively equipped with the nut head that can cooperate with the pole screw thread mouth.Lead by the band nut head connects the positive and negative terminals of battery.Connected mode between this battery electrode column is tradition very, and it needs the operator to dock one by one with lead, operate very time-consuming, require great effort, and the connection lead that exposes can increase the space that is provided with of battery pack, also can make the connecting portion of battery electrode column seem very messy.
[summary of the invention]
The objective of the invention is deficiency, a kind of lead that need not is provided, can finish the plug ducting type large capacity lithium ion battery that connects conducting between each battery plus-negative plate at above-mentioned high capacity lithium ion battery existence.
Plug ducting type large capacity lithium ion battery of the present invention comprises: be filled with electrolyte housing, stack the lithium ion battery core body of forming by positive and negative pole plate of polylith and barrier film; The uncoated substrate face end of the positive/negative plate of battery core body is arranged in the opposite direction, positive and negative plate uncoated substrate face end is connected by the bookbinding of bundle head respectively, it is characterized in that: the two ends, the positive back side of housing offer the fenestra that is provided with for battery positive and negative electrode accessory power outlet hole respectively; Offer socket mounting hole on the bundle head of two ends respectively, be respectively equipped with jack in the socket mounting hole towards opposite resilient socket assembly perpendicular to pole piece.
The jack of described resilient socket assembly is equipped with the conduction bearing pin that is shorter in length than two socket hole depths.
The design principle of plug ducting type large capacity lithium ion battery of the present invention is: by the structural improvement of socket aperture vertically is set at the battery two ends, utilize conduction bearing pin and patching of two battery socket holes up and down, realize that the both positive and negative polarity output of two batteries that stack up and down is connected.
Plug ducting type large capacity lithium ion battery design science of the present invention, rational in infrastructure.The output of its dexterously that battery is traditional raised type pole changes over the output of socket mouth, changes lead and is connected to the latch connection.The latch syndeton is simple, and the plugging position of good conductivity, each battery does not appear, and its disguise is fabulous, between each battery by the connection of bearing pin, no matter line up discharging, or layer pile stack, need not support and all can make it that stability is preferably arranged.Technical solution of the present invention is applicable to liquid lithium ionic cell, semisolid lithium ion battery, also is applicable to the solid polymer lithium ion battery.
The concrete structure of plug ducting type large capacity lithium ion battery of the present invention by the following drawings and
Embodiment provides in detail.
