Abstract
The invention discloses an electric connection structure of single batteries and a junction conductor in a battery pack. The structure comprises the battery pack provided with the batteries, battery poles connected to the single batteries, and the junction conductor. The battery poles and the junction conductor are connected in an adhesive mode through conductive glue. The conductive glue has a certain hot melt temperature. The single batteries in the battery pack can be reliably connected with the junction conductor. When current is too large or short-circuit happens or the single batteries are too high in thermal runaway temperature, the faulty single batteries are disengaged from the battery pack, and the safety protection function is achieved.
Description
Technical field
The present invention relates to a kind of battery in battery pack monomer and the electric connection structure of the conductor that confluxes, belong to cell safety technical field.
Background technology
In recent years, battery pack is widely used, and especially portable electric appts is if notebook computer, panel computer are to electric bicycle, electric automobile, back-up source etc.When manufacture has the battery pack of multiple battery cell, each battery cell all needs to be connected to by electric connection the conductor that confluxes and gets on.Current technology is mainly welded, and has the technology such as electric resistance welding, Laser Welding, ultrasonic bonding.The feature of these technology is all to produce high temperature, and after battery goes wrong, battery is also connected to by joint and confluxes on conductor.The electric connection improved two of fuse is connected to battery and confluxing on conductor, but this electric connection also can only excessive to electric currents such as short circuits when, battery cell is separated from battery pack.
Summary of the invention
The present invention seeks to: for the problems referred to above; a kind of battery in battery pack monomer is proposed and the electric connection structure of the conductor that confluxes; each battery cell in battery pack is reliably connected with the conductor that confluxes; and, short circuit excessive at electric current or battery cell thermal runaway temperature too high time; fail battery monomer is spun off from battery pack, plays the effect of safeguard protection.
Technical scheme of the present invention is: the electric connection structure of a kind of battery in battery pack monomer and the conductor that confluxes, comprise there are several battery cells battery pack, be connected to the battery electrode column on described battery cell and the conductor that confluxes, described battery electrode column and conflux conductor by conducting resinl bonding connection, and described conducting resinl has certain heat melts temperature.
The present invention, on the basis of technique scheme, also comprises following preferred version:
Also comprise the fixed support for fixing described battery electrode column and conductor position of confluxing.
Described fixed support is provided with the conducting resinl collecting chamber for collecting conducting resinl after melting.
Described fixed support is provided with the conducting resinl runner between described conducting resinl and described conducting resinl collecting chamber and the valve for closed/this conducting resinl runner of conducting.
It is formulated that described conducting resinl adds conducting particles by thermoplastic resin.
Advantage of the present invention is: when electric current is excessive, short circuit or battery cell thermal runaway temperature too high time, battery electrode column on respective battery monomer and the conducting resinl fusing of confluxing between conductor flow away, thus battery electrode column and the syndeton between conductor of confluxing are disconnected, this fail battery monomer is spun off in time from battery pack, effective partition can cause the electric current of security incident, has ensured the fail safe that battery uses.
Accompanying drawing explanation
Fig. 1 is the structure diagram of the embodiment of the present invention;
Wherein: 1-battery electrode column, 2-confluxes conductor, 3-battery cell, 4-fixed support, 5-conducting resinl.
Embodiment
Fig. 1 shows this battery in battery pack monomer of the present invention and a specific embodiment of the conductor electric connection structure that confluxes, it comprise there are several battery cells 3 battery pack, be connected to battery electrode column 1 on each battery cell 3 described and the conductor 2 that confluxes, described battery electrode column 1 and conflux conductor 2 by conducting resinl 5 bonding connection, and described conducting resinl has certain heat melts temperature.When electric current is excessive, short circuit or battery cell thermal runaway temperature too high time, respective battery pole 1 and the conducting resinl fusing of confluxing between conductor 2 flow away, thus battery electrode column 1 and the syndeton between conductor 2 of confluxing are disconnected, this battery cell is spun off in time from battery pack.
Further, this example is also provided with fixed support 4, and this fixed support 4 is for the relative position of fixing described battery electrode column 1 with the conductor 2 that confluxes, and after preventing described conducting resinl melting, battery electrode column 1 again contacts with the conductor 2 that confluxes and links together.Fixed support 4 is provided with the location notch for self-contained battery pole 1 and conductor 2 position of confluxing.
In addition, this example is provided with the conducting resinl collecting chamber for conducting resinl after collecting melting on also described fixed support 4, but also the valve of the conducting resinl runner be provided with on fixed support 4 between described conducting resinl and described conducting resinl collecting chamber and for closing/this conducting resinl runner of conducting.
Bond battery electrode column 1 using conducting resinl 5 and conflux conductor 2 time, before conducting resinl 5 solidifies, described valve closing (conducting resinl runner is in closed state), the conducting resinl 5 of liquid cannot flow in conducting resinl collecting chamber, to facilitate the connection of conducting resinl 5 pairs of battery electrode columns 1 and the conductor 2 that confluxes.When conducting resinl 5 solidify and by battery electrode column 1 and conductor 2 stable connection that confluxes after, described valve open (conducting resinl runner is in closed conducting state), now if electric current is excessive, short circuit or battery cell thermal runaway temperature too high, conducting resinl just can melt and flow away by conducting resinl runner inflow conducting resinl collecting chamber, is spun off in time by this battery cell from battery pack.The design of conducting resinl runner and conducting resinl collecting chamber, can prevent on the one hand the conducting resinl of melting to run helter-skelter contaminated environment, the conducting resinl of melting can be avoided on the other hand to flow into battery dangerous position and cause short circuit.
Certainly, above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to people can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
