Determine the effect of positive strap, touch with negative pole box hat wall knot after preventing positive strap from departing from resettlement section.
Description of the drawings
Fig. 1 is a structural representation of the utility model battery cap.
Fig. 2 is a structural representation of a box hat cylindrical lithium ion battery sealing ring of the battery cap of Fig. 1.
In figure：100th, battery cap；10th, box hat cylindrical lithium ion battery sealing ring；12nd, main body；13rd, installation portion；14th, every
From circle；16th, resettlement section；20th, steel cap；30th, thermistor；40th, explosion-proof valve；50th, positive strap.
Specific embodiment
Fig. 1 to Fig. 2 is referred to, a kind of battery cap 100 includes a box hat cylindrical lithium ion battery sealing ring 10, a steel cap
20th, a thermistor 30, an explosion-proof valve 40 and a positive strap 50.
The box hat cylindrical lithium ion battery sealing ring 10 include a main body 12, from the main body 12 extend every
From circle 14, the cage ring 14 surrounds a resettlement section 16.The box hat cylindrical lithium ion battery sealing ring 10 also includes an installation
Portion 13, the installation portion 13 extend from the cage ring 14 near 12 one end of the main body.In one embodiment, the steel
Shell cylindrical lithium ion battery sealing ring 10 is made up of insulating materials.The positive strap 50 is made of an electrically conducting material.Real one
Apply in example, the positive strap 50 is made of aluminum.
When assembling the battery cap 100, the steel cap 20, thermistor 30 and explosion-proof valve 40 are installed on the main body 12
Interior.The steel cap 20 and the explosion-proof valve 40 are located at the opposite sides of the thermistor 30 respectively.The positive strap 50
And one positive pole ear be contained in the resettlement section 16 and contact with the explosion-proof valve 40, the cage ring 14 surround the positive pole company
The edge of contact pin 50 causes battery to prevent the positive strap 50 and the positive pole ear from contacting with a GND box hat
Short circuit.The cage ring 14 also acts as the effect for clamping the positive strap 50, during preventing the battery testing, the electricity
Pond block 100 deforms, and the positive strap 50 is come off from the battery cap 100, causes battery short circuit.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
Corresponding change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
