Description

Self-disconnecting USB charging socket interface

Technical field

The utility model relates to a kind of Self-disconnecting USB charging socket interface.

Background technology

Along with popularizing of the mobile digital electronic products such as mobile phone, MP3 player, digital camera, this electronic product has been worked out unified charged side standard usb interface; Therefore USB charging socket interface is used widely, and appears on the transducer of normal domestic power connector; General USB charging socket interface one side is to be converted to direct current 5V for opposite side load charging by alternating current 220V through the transformation rectification module, after the USB plug of mobile digital electronic equipment is extracted from this USB charging socket interface, the transformation rectification module still is in charged operating state, the waste electric energy, cause the transformation rectification module to waste, reduced useful life; The transformation rectification module falls in the USB charging socket interface accidentally such as foreign matter when electriferous state in addition, may cause short circuit to cause that the transformation rectification module damages, and has affected the normal use of USB charging socket interface.

Summary of the invention

Technical problem to be solved in the utility model is a kind of Self-disconnecting USB charging socket interface; this jack interface provides effective protection to the transformation rectification module; avoided wasting in charged state not; saves energy; avoided foreign matter to fall into the short circuit that causes; improve the useful life of transformation rectification module, guaranteed the normal use of USB charging socket interface.

For solving the problems of the technologies described above, the utility model Self-disconnecting USB charging socket interface comprises transformation rectification module and USB charging socket, described transformation rectification module input connects the 220V power supply, described transformation rectification module output connects described USB charging socket, this interface also comprises the isolated sensitive switch of often opening, the described isolated sensitive switch of often opening is located in the described USB charging socket and the isolated outstanding USB charging socket inner surface of action compressing tablet of often driving sensitive switch, and the described isolated normally opened contact of often driving sensitive switch is serially connected with in described transformation rectification module input and the 220V power supply link circuit.

Because the utility model Self-disconnecting USB charging socket interface has adopted technique scheme, be that this jack interface comprises transformation rectification module and USB charging socket, transformation rectification module input connects the 220V power supply, transformation rectification module output connects the USB charging socket, this interface also comprises the isolated sensitive switch of often opening, the isolated sensitive switch of often opening is located in the USB charging socket and the isolated outstanding USB charging socket inner surface of action compressing tablet of often driving sensitive switch, and the isolated normally opened contact of often driving sensitive switch is serially connected with in transformation rectification module input and the 220V power supply link circuit.This jack interface provides effective protection to the transformation rectification module, has avoided wasting in charged state not, has avoided foreign matter to fall into the short circuit that causes, and has improved the useful life of transformation rectification module, has guaranteed the normal use of USB charging socket interface.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is the structural representation of the utility model Self-disconnecting USB charging socket interface.

Embodiment

As shown in Figure 1, the utility model Self-disconnecting USB charging socket interface comprises transformation rectification module 1 and USB charging socket 2, described transformation rectification module 1 input connects the 220V power supply, described transformation rectification module 1 output connects described USB charging socket 2, this interface also comprises the isolated sensitive switch 3 of often opening, the described isolated sensitive switch 3 of often opening is located in the described USB charging socket 2 and isolated action compressing tablet 31 outstanding USB charging socket 2 inner surfaces of often driving sensitive switch 3, and the described isolated normally opened contact of often driving sensitive switch 3 is serially connected with in described transformation rectification module 1 input and the 220V power supply link circuit.

This jack interface is simple in structure, and is easy to make, saves electric energy, improved fail safe and useful life, can be used in common power extension socket, wall socket, the charger, greatly made things convenient for the charging operation of mobile digital electronic equipment; Transformation rectification module 1 input AC 220V voltage, output direct current 5V voltage, when the mobile digital electronic equipment charges, the USB plug 4 of equipment is inserted in the USB charging socket 2 of this interface, when inserting, the USB plug 4 of equipment is depressed the isolated action compressing tablet 31 of often driving sensitive switch 3, then the normally opened contact of isolated sensitive switch 3 is closed and connect the link circuit of transformation rectification module 1 and 220V power supply, the normally opened contact of isolated sensitive switch 3 can be serially connected with in the live wire loop, also can be serially connected with in the zero line loop, can to mobile digital electronic equipment charge by this interface this moment, charge complete after, extract the USB plug 4 of equipment, the action compressing tablet 31 of isolated sensitive switch 3 sets back, isolated sensitive switch 3 normally opened contacts disconnect and cut off the link circuit of transformation rectification module 1 and 220V power supply, 1 outage of transformation rectification module has been avoided wasting, zero loss when realizing not charging has improved the useful life of transformation rectification module 1 and has saved electric energy; Simultaneously when charged state not, because 1 outage of transformation rectification module, and the action compressing tablet 31 of isolated sensitive switch 3 is not charged, can not cause short circuit even foreign matter falls in the USB charging socket 2 yet, provides effective protection to transformation rectification module 1.
