Description
Technical field
This utility model relates to accumulator manufacture field, particularly relates to a kind of set of cells improving bulk strength and circuit stability.
Background technology
Existing lithium battery is obtain required running voltage and higher capacity with electric current, generally becomes set of cells to use battery series-parallel connection.Set of cells connection in series-parallel is usually and first carries out parallel connection between monomer battery core, it is thus achieved that required capacity, then batteries in parallel connection is together in series, it is thus achieved that certain running voltage.But this occupation mode there is also some problems.Such as battery once there is short circuit, the battery broken down will exhaust rapidly the electricity in other batteries, and causes fire.Therefore, in set of cells, the secure connection of each battery is just most important.
The connection in series-parallel of lithium battery is to utilize metal joining strips to be connected by spot welding with the metallic plate of battery positive/negative.Namely spot welding be that weldment is soldered on indivedual points of joint contact surface, and spot welding requires that metal has good plasticity.Nickel metal quality is tough and tensile, has good plasticity, is usually used in metal joining strips during lithium battery connection in series-parallel.During spot welding, the plate overlap joint welded is assembled, is pressed between two column copper electrodes, applies pressure.When by sufficiently large electric current, produce substantial amounts of resistance heat in the contact position of plate, the metal of most for center thermal region is quickly heated to be high-ductility, continues to pressure, after turn-off current, metal cools, form a solder joint.
The Chinese patent literature that common nickel strap such as publication number is CN203192901U discloses a kind of lithium ion battery connection in series-parallel nickel strap, including nickel strap main body, nickel strap main body both sides have nickel strap main body fixing hole, the both sides of nickel strap main body are connected to resettable fuse by nickel strap main body fixing hole laser spot welding, the both sides of resettable fuse have nickel strap agent localization hole and hole, nickel strap split location, nickel strap agent localization hole is corresponding with nickel strap main body fixing hole, the outside of resettable fuse is connected to nickel strap split by nickel strap split fixing hole laser spot welding, hole, nickel strap split location is corresponding with nickel strap split fixing hole.
The Chinese patent literature that publication number is CN202839821U discloses more than one and multi-string battery nickel strap, is also structure as a whole including circumferential body and the connection sheet being fixed on circumferential body outer of integrative-structure, circumferential body and connection sheet.Use this utility model many and multi-string battery nickel strap not only solves the rosin joint of existence, short circuit, inefficiency, CURRENT DISTRIBUTION unequal phenomenon when using in-line nickel strap assembled battery in prior art, and reduce the cost of material of nickel strap.
Multiple lithium battery monomers utilize nickel strap to be encapsulated in box body after carrying out circuit connection again, series connection and parallel relationship is there is between cell, diverse location on circuit is to the requirement on electric performance of nickel strap and differs, additionally before Package boxes, multiple lithium battery monomers only rely on nickel strap and connect, insufficient strength on the whole, is not easy to mobile and transhipment.
Utility model content
This utility model provides a kind of set of cells, by the improvement of nickel belt structure and arrange conductive frame and can improve bulk strength and circuit stability.
A kind of set of cells improving bulk strength, the multiple cells on support including support and fixed arrangement, every two rows of described cell are one group, the nickel strap adopting integrative-structure with the same side between group connects, the same side of all groups is fixed with the conductive supporting plate being covered on nickel strap, this conductive supporting plate is provided with to dodge multiple vacancy sections of nickel strap and cell welding position, and conductive supporting plate is fixed by screw and support.
In this utility model, firstly for the cell with group, the nickel strap adopting integrative-structure carries out circuit connection, moreover it is fixed with conductive supporting plate in the both sides of support, so the mechanical strength of entirety is substantially increased, owing to conductive supporting plate is covered in outside nickel strap, it is possible to avoid snapping between nickel strap and cell, it is ensured that the stable and safety of electric property.
As preferably, all nickel straps being in support homonymy are all welded on conductive supporting plate.Ensure so further and improve intensity.
As preferably, described support includes the added and undercarriage fastened mutually by Elastic buckle, and each cell is clamped between added and undercarriage.Although existing many supports be also by added and under be configured to, but there is no annexation between added and undercarriage, after cell assembles, bulk strength is poor, easily misplaces during pile, and of the present utility model added and undercarriage mutually abuts and is combined into body structure by Elastic buckle.
As preferably, described conductive supporting plate is rectangle, and described vacancy section is the circular hole of matrix arrangement.
As preferably, described conductive supporting plate is crisscross frame structure.
All under the premise ensureing conductive supporting plate intensity, weight can be alleviated, and dodges the welding position of nickel strap and cell more than to two ways, it is prevented that to interfere spot welding processing.
For the ease of the connection of external circuit, as preferably, the edge of described conductive supporting plate is with bending, with being used for connecting the connecting hole of external circuit in bending.
In order to ensure locating effect, described conductive supporting plate is provided with the hole, location for wearing described screw with nickel strap, and support is provided with and the screwed hole of described screw fit.
In this utility model, by the improvement of nickel belt structure and arrange conductive frame and can improve bulk strength and circuit stability, it is to avoid snap between nickel strap and cell.
