Intelligent vehicle mounted terminal is as the part of intelligent transportation system; It is mounted on the vehicle; The various information of vehicle are gathered and stored, be connected with other equipment in the car, have the mobile unit of GPS location, GPRS wireless data transmission function through the CAN bus.Intelligent vehicle mounted terminal is to fail safe, the very large effect of having improved service quality of management, personnel and the vehicle of standard driver's behavior, car operation company.
Intelligent vehicle mounted terminal is as electronic equipment; Need supply power to it, intelligent vehicle mounted terminal is adopting when rechargeable battery powered, need be connected with charger through charge connector when the rechargeable battery of intelligent vehicle mounted terminal is charged; Imported the charge power supply of the charging chip of intelligent vehicle mounted terminal is directly exported by external charger by charge connector; Under abominable external environment condition, power surge possibly occur or receive exterior static interference on the charge power supply by charge connector output charging chip, fluctuation on a large scale appears in charge power supply voltage; Voltage instability fluctuation meeting impacts to whole intelligent vehicle mounted terminal; And when the charge power supply scope range of the fluctuation of voltage is big, big to the impact of intelligent vehicle mounted terminal, at this moment possibly cause permanent physical damage to intelligent vehicle mounted terminal.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of charge connector that is used for intelligent vehicle mounted terminal that can reduce the charge power supply scope range of the fluctuation of voltage is provided.
The purpose of the utility model mainly realizes through following technical scheme: the charge connector that is used for intelligent vehicle mounted terminal; Comprise charge connector, charging chip and interference signal TVS; Said charge connector is connected with power supply output line, and the other end that said power supply output line connects the charge connector end relatively is connected with charging chip; Said interference signal TVS comprises that magnetic bead and transient voltage suppress diode, and said magnetic bead is connected in series on the power supply output line of charge connector, and said transient voltage suppresses diode one end and is connected its other end ground connection with the power supply output line of charge connector.
Said charging chip is provided with charging inlet, and the link of said power supply output line and charging chip is provided with charging connector, the charging inlet coupling of said charging connector and charging chip, and charging connector embeds in the charging inlet.
Said charge connector is connected with power input line.The utility model is when charging to charging chip, and power input line is connected with charger.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model is provided with the interference signal TVS; Wherein the interference signal TVS comprises that magnetic bead and transient voltage suppress diode; The external power source surge of the big electric current of magnetic bead ability filtering small voltage; And for exterior static interference; Transient voltage suppresses diode can be in utmost point conducting and electrostatic interference introduced ground over the ground in the short time, thereby makes the utility model can reduce the charge power supply scope range of the fluctuation of voltage, avoids intelligent vehicle mounted terminal to be damaged.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is done further to specify, but the execution mode of the utility model is not limited thereto.
Embodiment:
As shown in Figure 1; The charge connector that is used for intelligent vehicle mounted terminal; Comprise charge connector, charging chip and interference signal TVS; Charge connector is connected with power input line and power supply output line, and power input line is used to connect charger, and the two ends of power supply output line are connected with charging chip with charge connector respectively.Charging chip is provided with charging inlet, and the link of power supply output line and charging chip is provided with charging connector, the charging inlet coupling of charging connector and charging chip, and charging connector embeds in the charging inlet.The interference signal TVS is connected on the power supply output line; It comprises that magnetic bead and transient voltage suppress diode, and magnetic bead is similar to inductance, during fabrication; Set its signal and have higher impedance to certain frequency range; Its high-frequency noise and spike that is used to suppress on the power line disturbs, and also has the ability that absorbs electrostatic pulse, and magnetic bead is connected in series on the power supply output line of charge connector; It is to the custom-designed device of electrostatic interference that transient voltage suppresses diode; It is for moment extra-high pressure (KV level), and the static discharge of minimum electric current (uA or even nA level) can be in utmost point conducting over the ground in the short time; Thereby reach the purpose of electrostatic interference being introduced ground; Protected intelligent vehicle mounted terminal, transient voltage suppresses diode one end and is connected with the power supply output line of charge connector, and transient voltage suppresses the other end ground connection that diode connects the power supply output line end relatively.
As stated, then can well realize the utility model.
