Abstract
The utility model relates to the technical field of chargers, in particular to a charger with an USB interface, which comprises a charger body, pins and an USB output interface, wherein the pins are located on the charger body and can be connected with external power supply, the charger body is involuted and plugged by a left main body part and a right main body part, and the pins are jointed by a cathode pin part and an anode pin part. A power supply pin of the charger uses a split type structure, and a joint portion of the cathode pin part and the anode pin part is jointed together by using a mutually jointed Morse taper structure. The charger with the USB interface guarantees the reliability and the inheritance of jointing the pins, also embodies the novelty of the split type structure, and is convenient to make and produce simultaneously. The pins of the charger further can be folded on the charger body, is convenient to carry, and is more practical.
Description
Technical field
The utility model relates to the charger technical field, particularly relates to a kind of charger that has USB interface.
Background technology
Along with popularizing of portable electronic products such as digital camera, MP3, PDA, for the also increase thereupon of demand of secondary cell.A large amount of uses of secondary cell have also promoted the charger development of secondary cell charge and have improved.
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 classes, and a class is conventional circular port, and another kind of is USB port.Along with the development of each electronic product technology is upgraded, the charger of USB interface is also more and more general.
And the pin that the prior USB charger is connected with mains supply is directly to protrude from outside the charger body mostly, because the charger pin all is integrated design, this whole pin configuration of continuing to use for many years can't bend, and Mechanical Builds is not easy to put in order and carry like this.
The utility model content
Problem to be solved in the utility model provides a kind of USB interface charger simple for structure, easy to use.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Design a kind of USB interface charger, include charger body, be positioned at pin that connects extraneous power supply and USB output interface on the charger body, described charger body by about two involutory grafting of main component form, described pin is formed by anodal pin spare and the mutual clamping of negative pole pin spare.
Anodal pin spare is made of anodal inserted sheet and the anodal inserted sheet insulator that is used for fixing anodal inserted sheet, negative pole pin spare is made of negative pole inserted sheet and the negative pole inserted sheet insulator that is used for fixing the negative pole inserted sheet, described anodal inserted sheet insulator one end is articulated in the left main component, the other end has spliced eye, and negative pole inserted sheet insulator is plugged in the anodal inserted sheet insulator spliced eye and with it and fixes.
The utility model has following remarkable result compared to existing technology:
Charger power pin in the utility model adopts split-type structural, and anodal pin spare is combined with the mutual clamping of bound fraction of negative pole pin spare.This designs simplification the structure of mfg. moulding die, reduce the technological requirement of assembling, the product structure symmetry is better.The pin interface that this charger is connected with power supply can be folded on the charger body, and it is practical more to be easy to carry.
Description of drawings
Fig. 1 is a contour structures schematic diagram of the present utility model; Fig. 2 is the structural representation after pin folds among Fig. 1; Fig. 3 is the structure chart after the utility model split.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1～3, a kind of USB interface charger, charger body 1 end face is provided with USB output interface 2, connect on the charger body bottom surface can with the pin 3 of extraneous power supply.Charger body by about two involutory grafting of main component form, charger internal electrical device is separately fixed in left main component or the right main component.Employing engages mode and links together between a left side main component 10 and the right main component 11.
The anodal pin spare of this charger is made of anodal inserted sheet 301 and the anodal inserted sheet insulator 302 that is used for fixing anodal inserted sheet, and negative pole pin spare is made of negative pole inserted sheet 311 and the negative pole inserted sheet insulator 312 that is used for fixing the negative pole inserted sheet.Anodal inserted sheet insulator is processed into cylindrical body, anodal inserted sheet insulator one end is articulated on the left main component, have prismatic spliced eye in the other end, negative pole inserted sheet insulator is processed into prismatic body, and negative pole insert-connecting plate insulator is plugged in to form in the anodal inserted sheet insulator spliced eye and makes two both positive and negative polarity pins structure of swing synchronously.For make between anodal inserted sheet insulator and the negative pole inserted sheet insulator cooperate more accurate, the Morse's taper structure can be adopted in two pin joint portions, it is more accurate to adopt the stationary fit of Morse's taper can make both locate cooperation, this structure has guaranteed reliability and the succession property that pin engages, pin adopts split-type structural simultaneously, be convenient to installing/dismounting, can also reduce the manufacturing cost of pin.
Anodal inserted sheet insulator one end is to be articulated on the left main component in the utility model structure, and when that is to say in negative pole inserted sheet insulator is plugged in anodal inserted sheet insulator, external force promotes anodal inserted sheet or negative pole inserted sheet, and two pins will rotate so.When not using charger, promoting pin makes the pin swing be affixed on the charger body, coordinate more in order to make pin rotate the monnolithic case that is affixed to charger, can offer a groove position in the charger body position that pin is pressed close to and rotate the pin that turns back to hold.
The pin interface that is connected with power supply of this charger can be folded on the charger body, and it is practical more to be easy to carry.
