And then insulation protection of the realization to electronic component, while electronic component being prevented to be corroded.Additionally by the encapsulating shell with it is several
The electronic component directly contacts, and then effectively conducts heat caused by electronic component work, improves radiating efficiency.Pass through
The protection board is formed using integrated injection molding, and then exempts and is nested with rubber shell, makes that more electronic components can be arranged on circuit board,
And then space utilization rate is improved, while reducing the efficiency that installation step improves assembling production.Simultaneously by using injection molding formed with
The encapsulating shell of the circuit board integral type connection, and then effectively improve the structural strength of the protection board.
One preferred embodiment is that the circuit board is equipped with the positive and negative connector and o pads for stretching out the encapsulating shell.
By above scheme as it can be seen that the positive and negative connector conducts electric energy for being connected with battery core, the o pads are used
Electric energy is exported in connecting with external loading.
Further preferred embodiment is that resin layer is coated on the outside of the battery core and the protection board, on the resin layer
Equipped with connecting hole compatible with the o pads, the side of the resin layer is equipped with thermovent, fills at the thermovent
There is heat-conducting layer.
By above scheme as it can be seen that make the lithium battery stronger reliable by the way that the resin layer is arranged, while realizing waterproof
It is dust-proof.The heat that battery core is dredged by the way that the heat-conducting layer is arranged keeps battery core work more stable.The heat-conducting layer is common thermally conductive
Silicone grease.
Further preferred embodiment is that the thickness of the resin layer and the heat-conducting layer is 0.2mm-1mm.
By above scheme as it can be seen that the thickness can guarantee has enough intensity while keeping the thickness of battery thin as far as possible.
The novel protected plate insulation-encapsulated technique the following steps are included:
A. firstly, several electronic components correspondence is welded on the circuit board；
B. by carrying out injection molding packaging to the circuit board and several electronic components, and then in the circuit board and several
Encapsulating shell is formed on the electronic component；
C. then by the positive and negative connector and the battery core welding assembly；
D. cladding layer protecting film forms battery pack outside the battery core and the protection board；
E. battery pack being fitted into shaping box, the shaping box includes the first lid and the second lid being hinged, and described
Setting connection shaping column and heat dissipation shaping column, second lid are equipped with inlet on one lid；
F. resin is injected in the shaping box from the inlet and forms the resin layer, resin connects into described in the process
It is limited when type column and the heat dissipation shaping column, and then forms the connecting hole and the thermovent, then beat the shaping box
It opens and battery is taken out and forms the heat-conducting layer in the thermovent coated with thermally conductive material.
By above scheme as it can be seen that directly carrying out injection sealed by using in the circuit board and several electronic components
It puts into and coats the encapsulating shell several electronic components completely, while keeping the encapsulating shell and the circuit board close
Connection protects electronic component to avoid part, aster and the risk of short circuit in this way.
