Abstract
The utility model belongs to the technical field of electronic products and provides a panel computer charger having a lightning protection function. The panel computer charger comprises a charging circuit and a three-phase plug and further comprises a high fusing protector, a voltage dependent resistor, a grounding terminal, a switch and a computer connector, wherein the high fusing protector, the charging circuit, the switch and the computer connector are sequentially and electrically connected, and the voltage dependent resistor is connected in parallel with the high fusing protector and is connected with the grounding terminal. The panel computer charger solves a problem that a panel computer charger in the prior art has no lightning protection function, and employs dual lightning protection measures to effectively avoid damage to the panel computer caused by lightning strokes in a rainy day.
Description
Technical field
The utility model relates to a kind of charger, is specifically related to a kind of panel computer charger with lightning protection function.
Background technology
This natural phenomena of thunder and lightning is one of unsafe factor of each household electrical appliance maximum, once electrical equipment is struck by lightning, gently affects electric property, heavy directly cause electrical equipment damage, also likely cause fire.Panel computer, as the important electrical equipment of daily life, seems particularly important to the lightning protection of panel computer, but classic flat-plate computer charger does not have lightning protection function.
Utility model content
The purpose of this utility model be overcome existing panel computer charger can not Lightning Protection.
For this reason, the utility model provides a kind of panel computer charger with lightning protection function, comprises charging circuit and 3-phase plug, also comprises high fuse protector, piezo-resistance, earth terminal, switch, ECU connectors; Described high fuse protector, charging circuit, switch, ECU connectors are electrically connected in turn, and described piezo-resistance is in parallel with high fuse protector electricity and be connected with earth terminal.
Above-mentioned piezo-resistance and high fuse protector are arranged in same seal.
On above-mentioned switch, be provided with indicator light.
The beneficial effects of the utility model: 1, structurally increased piezo-resistance and high fuse protector, piezo-resistance can import the earth by earth terminal by the overcurrent in thunderbolt, in the time that overcurrent after piezo-resistance shunting is still very large, high fuse protector disconnects, so just for panel computer provides dual lightning protection, thereby make panel computer safer; 2, structurally piezo-resistance and high fuse protector are placed in same seal structure is simplified; 3, on panel computer charger, be also provided with switching device, removed the trouble that repeats to plug ECU connectors from, charger is used more convenient; 4, on switch, being provided with indicator light makes user can clearly know the operating state of charger.
Accompanying drawing explanation
In order to be illustrated more clearly in utility model; be described in further details below in conjunction with accompanying drawing, so that reader is easier to understand, but do not represent that execution mode of the present utility model only limits to this; any technology of doing according to the utility model is extended or recreation, is all subject to protection of the present utility model.
Fig. 1 is a kind of structural representation of the panel computer charger with lightning protection function.
In figure: 1, charging circuit, 2, earth terminal, 3,3-phase plug, 4, high fuse protector, 5, piezo-resistance, 6, switch, 7, indicator light, 8, ECU connectors, 9, seal.
Embodiment
Embodiment 1:
The present embodiment provides a kind of panel computer charger with lightning protection function as shown in Figure 1, comprises charging circuit 1 and 3-phase plug 3, also comprises high fuse protector 4, piezo-resistance 5, earth terminal 2, switch 6, ECU connectors 8; High fuse protector 4, charging circuit 1, switch 6, ECU connectors 8 are electrically connected in turn, and piezo-resistance 5 is in parallel with high fuse protector 4 electricity and be connected with earth terminal 2.
Piezo-resistance 5 and high fuse protector 4 on original structure, are increased; piezo-resistance 5 can import the earth by earth terminal 2 by the overcurrent in thunderbolt; in the time that overcurrent after piezo-resistance 5 shuntings is still very large, high fuse protector 4 disconnects; so just for panel computer provides dual lightning protection; thereby make panel computer safer; on panel computer charger, be also provided with switching device, removed the trouble that repeats to plug ECU connectors from.
Embodiment 2:
On the basis of embodiment 1, piezo-resistance 5 and the high fuse protector 4 of this charger are arranged in same seal 9, and structure is simplified.
On the switch 6 of this charger, be provided with indicator light 7, the keying that this indicator light 7 can display power supply.
In sum, opening switch 6 chargers are normally worked, and in the time being struck by lightning, the overcurrent of major loop increases, and exceedes the threshold values of piezo-resistance 5, and piezo-resistance 5 resistances diminish, and play the effect of shunting, and the electric current of getting imports the earth by earth terminal.If at this moment still very large by the electric current of major loop; high fuse protector 4 will disconnect; thereby reach the object of dual lightning protection, this utility model has successfully solved the drawback that panel computer charger can not lightning protection, makes the panel computer safer in charging process.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection range of the present utility model, within the every and same or analogous design of the utility model all belongs to protection range of the present utility model.
