Description
Technical field
The invention belongs to resistance field, is related to combined resistance, especially a kind of to be used for for the anti-lightning strike of phone charger
Combined resistance.
Background technology
Combined resistance has the incomparable characteristic of traditional resistor, in medium, high frequency circuit, heavy current pulse circuit, high electricity
Can absorbing circuit, using the superiority for having uniqueness in intermittent circuit, especially in impact energy, peak power, high pressure, or low
Sense etc. various working at the same time in the presence of, combined resistance can be met the requirements.
Existing combined resistance is connected using conventional, electric-resistance with fuse more, and the high pressure range that fuse is born is limited, no
It can meet the impact of extra-high electric current or thunder and lightning.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of energy capability it is big be used for hand
The anti-lightning strike combined resistance of machine charger
The technical proposal for solving the technical problem of the invention is：
A kind of anti-lightning strike combined resistance for phone charger, including wire resistor, temperature and resistance, noninflammability silica gel apply
Material and plastic housing, install wire resistor and temperature and resistance, one end conducting wire of wire resistor and the one of temperature and resistance in plastic housing
Conducting wire is held to connect, the other end conducting wire of wire resistor and temperature and resistance is pierced by from plastic housing respectively, is filled in plastic housing non-ignitable
Property Silica gel coatings, the noninflammability Silica gel coatings coat wire resistor and temperature and resistance completely.
Moreover, the temperature and resistance includes the white rod of ceramics, non-ferrous metal fusing liquid coating, chapeau de fer, lead and insulating cement
Set, in both ends two chapeau de fers of symmetrical suit of ceramic white rod, respectively one lead of connection, the ceramics between two chapeau de fers apply two chapeau de fers on rod in vain
Brushed with non-ferrous metal fusing liquid coating, the outside cladding insulating gum cover of fuse in non-ferrous metal liquid coating and chapeau de fer.
Moreover, the thickness of the non-ferrous metal fusing liquid coating is 0.005~0.006mm.
Moreover, the plastic housing is made of PP materials.
The advantages and positive effects of the present invention are：
1st, this resistance when charging overload or lightning stroke when automatically power off, protect mobile phone.
2nd, this resistance is high pressure resistant, small, and performance is stablized, corrosion-resistant, humidity, anti-vibration.

The apparent size of this combined resistance：Long 11~12mm, thickness 5~6mm, high 6~7mm.
The present invention operation principle be：
Wire resistor generates heat in the state of big load, and heat transfer is to temperature and resistance, the maximum born of wire resistor
Temperature is 300 degrees Celsius, and the maximum temperature that temperature and resistance is born is 200 degrees Celsius, when temperature and resistance reaches 200 degrees Celsius,
Temperature and resistance first fuses, and protects circuit.
The wire resistor size is 2.5 × 7.0mm, and line footpath is 0.12~0.15mm, and winding turns are 7~9 circles, resistance
It is worth for 4.7 ± 0.02 Ω.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, on the premise of inventive concept is not departed from, various modifications and improvements can be made, these belong to the protection of the present invention
