Abstract
The utility model discloses a direct plugging type charger with a universal series bus (USB) interface. The charger comprises a charger body, a power plug pin, a USB output interface and an indicator lamp. The charger is characterized in that the charger body comprises a cover plate and a casing, the power plug pin is arranged at the middle position of the cover plate, the USB output interface and the indicator lamp are arranged at the bottom of the casing, and two lateral faces of the casing are correspondingly provided with plugging parts which are concave grooves. The Direct plugging type charger with the USB interface is simple in structure, firm, compact and easy to plug and is applied to secondary battery charging of appliances including mobile phones, Bluetooth, camera and the like.
Description
Technical field
The utility model relates to the charger technical field, the particularly a kind of band USB interface of electrical equipment such as mobile phone, bluetooth, camera, charger of convenient plug charging body of being applicable to.
Background technology
Along with the development of society, increasing small electric apparatus has got into each family, and like mobile phone, digital camera etc., and these family expenses small electric apparatus major parts all need be used charger, convert civil power the secondary cell charge of low dc voltage to electrical equipment to.Various chargers to secondary cell charge in the market are of a great variety, and pattern is different.But the output port that is used for to secondary cell charge output mainly is two types, and one type is conventional circular port, and another kind of is USB port.Along with the development and update of each electronic product technology, the charger of USB interface is also more and more general.
A kind of general mobile model charger for mobile phone is disclosed among the for example Chinese utility application prospectus CN20112506Y; For reaching purpose simple in structure, easy to use; The technical scheme of this utility model patent is: charger comprises housing, is positioned at the input plug of housing lower end, charging circuit board; Input plug is connected with the input of charging circuit board; Be provided with the cavity that is used for internal battery in the housing, be provided with the DC socket and the female socket of USB that are connected with the charging circuit board output in the upper end of housing, the data wire that passes through mobile phone first wife's band USB interface during use connects female socket of USB or patchcord connection DC socket; Voltage transitions through input plug input civil power and charging circuit board; Can directly charge or earlier storage battery charged mobile phone, make mobile phone under the situation that does not have civil power to connect, storage battery can conveniently charge to mobile phone.
A kind of USB interface charger is disclosed among the and for example Chinese utility application prospectus CN20125617U; For reaching purpose simple in structure, easy to use; The technical scheme of this utility model patent is: include charger body, be positioned at pin that connects extraneous power supply and USB output interface on the charger body; Charger body by about two involutory grafting of main component form, pin is formed by anodal pin spare and the mutual clamping of negative pole pin spare.Charger power pin in this utility model adopts split-type structural, and the Morse's taper textural association that mutual clamping is adopted in anodal pin spare and the joint portion of negative pole pin spare together.Both guarantee reliability and succession property that pin engages, embodied the novelty of split type pin configuration again.
Can find out that through above-mentioned two routine utility models the charger of prior art mostly adopts fixed pin and movable split type pin, when the plug charger, because charger all plugs through vertical mode with the charging body.The structure of this vertical plug in use if the operator squints to the direction that the charging body plugs, receives the spacing influence of mating holes to pin, is easy to cause the distortion of charging body and charger, thereby damages; Vertical in addition direct insertion design, shared socket position is big, the plug inconvenience need be improved.
Summary of the invention
For overcoming the deficiency of above-mentioned technology, the utility model provides a kind of compactness simple in structure, firm, the direct insertion easily band USB interface of plug charger.
A kind of direct insertion band USB interface charger; Comprise charger body, the power pin that can be connected, USB output interface and indicator light with external power source; It is characterized in that: said charger body comprises cover plate and housing, is provided with charging circuit in the cavity that cover plate and housing form, and charging circuit is electrically connected with power pin, USB output interface, indicator light; Power pin is located at the cover plate middle position; USB output interface, indicator light are located at housing bottom, and housing two sides correspondence is provided with the plug position, and said plug position is a Baltimore groove.The utility model adopts direct insertion design, and power pin is located at the cover plate middle position, the less directly plug in shared socket position during charging, and side is provided with the plug position can be in case hand be sliding, and plug is light, and is easy to use, avoids the plug of normal charge device painstaking.
As the described direct insertion band USB interface charger of the utility model is further limited, said cover plate and housing are formed by the ultrasonic wave pressing, are provided with lock screw between cover plate and the housing.The utility model adopts the ultrasonic waves pressing to add the structure of tightening up a screw and locking, and increases Mechanical Reliability, avoids the conventional supersonic risk of peeling off.
For preventing that hand is sliding, make things convenient for the charger plug, a kind of optimal way in plug position of the described direct insertion band USB interface charger of the utility model is: said plug position is provided with anti-skidding salient point.
For preventing that hand is sliding, make things convenient for the charger plug, the another kind of optimal way in the plug position of the described direct insertion band USB interface charger of the utility model is: said plug position is provided with anti-skidding lines.
The beneficial effect of the utility model is:
The structure of 1, tightening up a screw and locking through adopting the ultrasonic waves pressing to add increases Mechanical Reliability, avoids the conventional supersonic risk of peeling off;
2, through power pin being located at the cover plate middle position, adopt this direct insertion design, the shared socket position of charging is less, compact conformation, and advantages of small volume is easy to carry;
3, the plug position is provided with the sliding design of anti-hand, and plug is light, and is easy to use, avoids the plug of normal charge device painstaking.
