Disconnected hot hole 37 is not interconnected with any one perforation 32.There is at least one disconnected hot hole between two perforation 32 adjacent to each other
37.The design of disconnected hot hole 37 is for stopping thermal energy rapidly to transmit between each contact structures 33；Specifically, when any
When a battery 20 occurs to damage and erupt high fever substance, the thermal energy of high fever substance will be transmitted to conductive sheet body structure 30, pass through
The design of disconnected hot hole 37, the speed that will can be postponed thermal energy and be transferred to other contact structures 33, so as to extend one of battery
Core 20 damages and erupts high fever substance, all impacted to remaining battery 20 and generate the time of high temperature.
In the case where not influencing the structural strength of 31 entirety of ontology, the quantity of disconnected hot hole 37 can increase and decrease according to demand,
Not to be limited as shown in the figure.As shown in fig. 6, the external form of disconnected hot hole 37 is also possible to according to changes in demand, for example, be also possible to be in
It is now arcuation, the bending direction about the disconnected hot hole 37 for being rendered as arcuation then can be according to changes in demand, not with as shown in the figure
It is limited.
In specific implement, the width W3 of each disconnected hot hole 37 be can be between 0.8 millimeter to 1.5 millimeters；Disconnected hot hole
37 length L3 can be between 2 millimeters to 3 millimeters, and but not limited to this, and length L3, the width W3 of disconnected hot hole 37 can regard this
The size and its thickness of body 31 determine.As shown in figure 5, the thickness t of ontology 31 can be between 0.12 millimeter to 0.2 millimeter.
Also referring to Fig. 3 and Fig. 6, in practical applications, ontology 31 can also include multiple avoid holes 38, conductive sheet
When body structure 30 is fixed on fixing seat 10, multiple fixed structures 13 of fixing seat 10, which can correspond to, is piercing in multiple avoid holes 38.Gu
The fixed structure 13 of reservation 10 can be the structure for be combineding with each other with another fixing seat 10, or can also fixing seat 10 with
The structure that other components (the e.g. outer cover etc. of cell apparatus 100) be combined with each other.
In the case where not influencing 31 overall structural strength of ontology, each avoid holes 38 be can be and at least one hot hole that breaks
37 are interconnected.It connects as shown in figure 3, each avoid holes 38 can be there are two the disconnected hot hole 37 for being rendered as strip, it is each
The external form and its length for two disconnected hot holes 37 that avoid holes 38 are connected can be roughly the same or not identical.By with keep away
The design for the disconnected hot hole 37 for allowing hole 38 to be connected will can make each perforation 32 all around all be provided with disconnected hot hole 37, so as to
When substantially postponing the generation of any battery core 20 damage and gushing out high fever substance, conductive sheet body structure 30 transfers thermal energy to other
The speed of battery 20.
As shown in fig. 6, each be also possible to be rendered as arcuation, position with the disconnected hot hole 37 interconnected of avoid holes 38 external form
Perforation 32 between two avoid holes 38 then can be disconnected 37 institute of hot hole of four substantially connect with two avoid holes 38
It surround.Also that is, four disconnected hot holes 37 for being located at the both sides of the same perforation 32 can be generally around be it is round, also that is, being located at
Four disconnected hot holes 37 of the both sides of same perforation 32, which can be, to be had and 32 roughly the same external forms of perforation.
