Abstract
The utility model provides a lead capable of automatically disconnecting for protection. The lead comprises a metal lead and a sheath coating the metal lead, wherein the metal lead is formed by more than one strand of metal wire. The lead capable of automatically disconnecting for protection is characterized in that the metal wire is formed by stranding or arranging a plurality of metal filaments in a staggered manner. The lead capable of automatically disconnecting for protection is formed by stranding or arranging the plurality of metal filaments in a staggered manner, has good conductivity, can be disconnected for protection when being subject to strong pulling force, cannot damage battery pack of the electric vehicles or cause short circuit of a single battery or multiple batteries, can effectively guarantee the safety of battery pack of the electric vehicles, and can overcome the serious consequences brought by the connecting manner of the existing battery pack.
Description
Technical field
The utility model relates to a kind of lead that disconnects protection, especially relates to a kind of lead of the disconnected protection of using at electric automobile.
Background technology
At present, battery pack generally connects battery pack by hard copper bar or soft copper bar on the electric automobile, is connected on the battery electrode column closely.The safety of battery pack mainly ensures that by a fuse of battery pack end also the someone imagines the centre that this fuse is placed on battery pack on the electric automobile, and it mainly acts on is to shield when the short circuit of battery pack integral body.There are two serious potential safety hazards in above-mentioned this mode: one, clashed into or exist certain brute force to pull under the strength when electric automobile, intercell connector is owing to be difficult to break, will damage cell inside, cause the short circuit of inside battery large tracts of land, make battery produce high temperature and then burning; Two, when intercell connector is broken, may make the multiple batteries short circuit, fuse can't work, thereby causes serious consequence.
In sum, there are the following problems in the prior art; When electric automobile is clashed into or exists certain brute force to pull under the strength, existing intercell connector may produce the battery pack in the electric automobile and destroy, and make single battery or multiple batteries short circuit, may have serious consequences.Therefore, can't effectively guarantee the safety of batteries of electric automobile group, make the certain hidden danger of security presence of electric automobile.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of lead that disconnects protection; can lead be subjected to certain brute force pull strength the time; lead disconnects protection; can not produce the battery pack of electric automobile and destroy, make single battery or multiple batteries short circuit; can ensure the safety of batteries of electric automobile group effectively, overcome the serious consequence that the connected mode of existing battery pack may be brought.
For achieving the above object; the utility model proposes a kind of lead that disconnects protection; comprise the sheath of plain conductor and coated metal lead, described plain conductor is made up of the metal wire more than one, it is characterized in that: described metal wire is formed by the staggered bundle strand of some wires or arrangement.
As preferably, described metal wire is formed by some wire weavings, can disconnect when being subjected to certain force.
As preferably, described metal wire is staggered by some wires and forms, and can disconnect when being subjected to certain force.
As preferably, described wire adopts the nickel plating circular copper wire, equal in length, and every one metal wire length is 1～10cm, is convenient to make.
As preferably, described wire adopts the nickel plating circular copper wire, equal in length, and every one metal wire length is 4～6cm, is convenient to make.
As preferably, described sheath adopts high temperature resistant telescopic material, can powerful disconnect when pullling strength being subjected to.
The beneficial effects of the utility model: adopt the staggered bundle strand of wire or arrange to form; and has conductibility well; the powerful protection that disconnects when pullling strength can be subjected to; can not produce the battery pack of electric automobile and destroy, make single battery or multiple batteries short circuit; can ensure the safety of batteries of electric automobile group effectively, overcome the serious consequence that the connected mode of existing battery pack may be brought.
