Abstract

The utility model provides a vehicle-mounted charger. The charger comprises a plug housing, and an interface housing; a metal positive electrode is fixedly arranged on a front end face of the plug housing, the metal positive electrode is molded into a micro-convex spherical surface, and is electrically connected with a spiral positive electrode connecting wire; an interface end of the interface housing is provided with a USB interface for connecting a device to be charged, and a metal negative electrode is fixedly connected with an outer ring of a plug end of the interface housing; a port housing adopting light-penetrable material is arranged at an opening of the interface end of the interface housing in a clamping manner; and the inner diameter of a rear end circular ring body of the plug housing is smaller than that of a front end circular ring body, and the rear end circular ring body is slidably arranged on the plug end of the interface housing. A positive electrode elastic head and a negative electrode elastic head of the vehicle-mounted charger adopt metal fixing pieces, electric interfaces are large, and in use, electric connection performance of the charger is stable; and the plug housing with the positive electrode elastic head embedded is slidably arranged, so when the charger is inserted into a cigar lighter socket, one can clearly sense that the charger is contacted in place. The vehicle-mounted charger is advantaged by saving electric energy and having long service life.

Description

A kind of onboard charger

Technical field

The utility model relates to a kind of electronic product that is used to charge, particularly a kind of onboard charger that improves structure, longer service life.

Background technology

Onboard charger be a kind of direct current imported, can be inserted in the charger on the automobile cigarette lighter socket; Use when can person easy to use going out or travelling; Its structure comprises shell body, charging circuit board, positive contact, negative contact terminal, charging inlet at least, and existing onboard charger generally is provided with anodal elastic head at front end face, and the sidewall of shell intercalation part is provided with the negative pole elastic head; Its deficiency has: anodal elastic head and negative pole elastic head are the spherical metal body; Contact-making surface is little, and elastic failure appears in elastic construction easily, causes stuck situation; When simultaneously charger inserts the cigar lighter socket, whether insert fully and effectively contact can only feel with staff, be easy to generate and insert not in placely, or insert and also firmly causing charger to damage after putting in place; In addition, such charger generally inserts cigar lighter socket circuit board and promptly is in "on" position, causes electric energy loss to a certain degree.

The utility model content

The purpose of the utility model is that anodal elastic head and the negative pole elastic head contact-making surface to present onboard charger is little, and elastic failure appears in elastic construction easily, causes stuck situation; When reaching charger insertion cigar lighter socket, whether insert also effectively contact fully and can only feel, reach the deficiency that causes electric energy loss to a certain degree easily with staff; A kind of onboard charger is provided, and the anodal elastic head of this onboard charger and negative pole elasticity adopt the metal stator, and electric interface is big; The electrical connection properties of charger is stable during use; And the housing of setting anodal elastic head slides and is provided with, and when charger inserts the cigar lighter socket, contacts the clearly perception that puts in place.

In order to solve above-mentioned prior art problem, the technical scheme of the utility model is:

The utility model onboard charger comprises plug casing, interface hull;

The front end face of said plug casing is installed with metal positive-pole, and said metal positive-pole is shaped to the sphere of a dimpling, and is electrically connected a spiral helicine anodal line, and the FUSE element of the other end of anodal line and a renewable type is electrically connected;

Be provided with circuit control panel in the said interface hull; The plug end of said control circuit board is electrically connected with FUSE element, negative pole line respectively; The interface end of interface hull is provided with and is used to connect the USB interface that needs charging device, and the plug end outer ring of interface hull is connected with the metal negative pole of annular;

The opening clamping of said interface hull interface end is provided with a port housing, and said port housing forms the rectangular through holes of coupling USB interface, and said port housing adopts the light-permeable material, and said charger leans on the inner face of port housing to be provided with indicator light;

The toric internal diameter in the rear end of said plug casing is less than the toric internal diameter of front end; And slide and be arranged at the plug end of interface hull; When charger inserts the cigar lighter socket; The rear end torus of plug casing can slip into the receiving space of interface hull and make that end face contacts with the front end face of metal negative pole thereafter, contacts the clearly perception that puts in place.

Said charger inserts cigar lighter and electrically contacts when good, and indicator light is shown in green, inserts load and when charging, indicator light is shown in red.

A kind of onboard charger of the utility model, its beneficial effect has: the anodal elastic head of this onboard charger and negative pole elasticity adopt the metal stator, and electric interface is big, and the electrical connection properties of charger is stable during use; The plug casing of setting anodal elastic head slides and is provided with, and when charger inserts the cigar lighter socket, contacts the clearly perception that puts in place; Circuit board could be communicated with power supply when USB interface inserted load, saved electric energy, and improved useful life.
