Abstract

One kind is without electric safe charging socket automatic power-off protection device, including New-type charge socket and relay；New-type charge socket includes three positive pole, negative pole, ground wire contact pins；The positive pole contact pin is adopted as split type, including A contact pins and B contact pins, negative pole are independent C contact pins；The relay provides work energy and conveying electric energy by New-type charge socket for relay；The output end of relay is connected to follow-up battery；A contact pins are connected to the input of relay；B contact pins and C contact pins provide work electricity consumption for relay.The utility model product is to realize charging socket both positive and negative polarity charging contact pin and accumulator anode and cathode break link, realizes that charging socket is in electroless state.The effect and benefit of this novel product are that solve exposed to the outside potential safety hazard easily got an electric shock.Thus thoroughly solves injury caused by conductor easily forms short circuit of getting an electric shock with both positive and negative polarity contact pin.

Description

One kind is without electric safe charging socket automatic power-off protection device

Technical field

One kind be the utility model is related to without electric safe charging socket automatic power-off protection device.

Background technology

The defects of existing product is that charging socket inner space is small, and both positive and negative polarity contact pin distance is near, and charge port positive and negative polarities begin Linking status is in battery eventually, but also is an exposure to the position easily touched, charge port is also substantive without what Protection device measure, metal or electric conductor are easily directly entered or touched the both positive and negative polarity of charging socket, got an electric shock so as to be formed The potential safety hazard of short circuit, such as the charging socket of battery truck, often there is child and made by the conductors such as coin or key, insertion charge port Life-long disabilities are caused into short-circuit high temperature scald.The parameter of electromobile battery is 48 volts of 5 peace, has exceeded the direct current safety electricity of country 36 volts are pressed, so potential safety hazard be present.

Utility model content

The utility model solve technical problem be：Overcome the deficiencies in the prior art, there is provided one kind is inserted without electric safe charging Mouth automatic power-off protection device.Solve charge port positive and negative polarities contact pin and be in the state linked with battery all the time, so as to make Into the potential safety hazard of electric shock.

The technical solution of the utility model is：It is a kind of without electric safe charging socket automatic power-off protection device, it is including new Charging socket and relay；New-type charge socket includes three positive pole, negative pole, ground wire contact pins；The positive pole contact pin is adopted as It is split type, including A contact pins and B contact pins, negative pole are independent C contact pins；The relay is carried by New-type charge socket for relay For work energy and conveying electric energy；The output end of relay is connected to follow-up battery；A contact pins are connected to the input of relay End；B contact pins and C contact pins provide work electricity consumption for relay.Filled between the A contact pins and B contact pins by insulating materials.

The utility model compared with prior art the advantages of be：The utility model product is to realize charging socket both positive and negative polarity Charge contact pin and accumulator anode and cathode break link, realizes that charging socket is in electroless state.Existing product charging socket is positive and negative For pole contact pin in spite of in charged state, charge port positive pole and negative pole are electriferous state all the time because it all the time with battery It is the state of connection, so potential safety hazard be present.The effect and benefit of this novel product are that solve easily to touch exposed to outside The potential safety hazard of electricity.Thus thoroughly solves injury caused by conductor easily forms short circuit of getting an electric shock with both positive and negative polarity contact pin.

Brief description of the drawings

Fig. 1 is the utility model theory of constitution block diagram.

Fig. 2 is the circuit catenation principle figure for realizing the product function.

Fig. 3 is the split type contact pins A of positive pole and B after this improvement.

Embodiment

It is theory of constitution block diagram of the present utility model as shown in Figure 1, including New-type charge socket and relay；New-type charge Socket includes three positive pole, negative pole, ground wire contact pins；As shown in figure 3, the positive pole contact pin is adopted as split type, including A contact pins With B contact pins, negative pole is independent C contact pins；The relay provides work energy and conveying by New-type charge socket for relay Electric energy；The output end of relay is connected to follow-up battery；A contact pins are connected to the input of relay；B contact pins and C contact pins are Relay provides work electricity consumption.Filled between the A contact pins and B contact pins by insulating materials；

The course of work is；When power source charges plug is connected charging with charging socket both positive and negative polarity, while also can be by Fig. 2 positive poles A and B split contact pins hold together, while positive pole B and negative pole C provide inputing power for relay, so that by positive pole A contact pins Connection movable contact triggering, the positive pole of the positive pole of battery and charger is connected as a single entity, negative pole without relay directly with Battery terminal negative connects, so as to reach charge mode.If pulling out charging plug, charge port positive pole A as shown in Figure 2 and B contact pins Disconnect, power-off purpose is realized so as to cause relay to be stopped.If Fig. 3 is the split type contact pins A of positive pole and B after improving Structure.

Charging socket positive pole can form electric shock short circuit, the positive pole after improving with negative pole before no improvement Both positive and negative polarity contact pin will not be connected because of conductor with negative pole causes short circuit of getting an electric shock.Such as battery truck charging socket in daily life, Both positive and negative polarity occurs that electric shock short circuit causes the person and property safety with instantaneous high-temperature when meeting conductor.

The product plug positive pole uses split type contact pin, the contact pin shape invariance of negative pole and ground wire.Relay is adopted at present With 10 48 volts of peaces, this data can unrestrictedly change according to actual conditions.
