Abstract

The utility model relates to a car charger and solves the problem that the anode and the cathode of the existing car charger can loose from the anode and the cathode of a storage battery of an automobile easily. The car charger comprises a case, a connecting device, a printed circuit board (PCB), an anode and a cathode, wherein the connecting device is used for being connected with a to-be-charged product; the PCB is installed in the case; and the anode and the cathode correspond to the anode and the cathode of the storage battery of the automobile respectively, are both in cylindrical shapes, sleeved on the surface of the case, and electrically connected with the PCB in the case. According to the car charger, the anode and the cathode well contacts with the anode and the cathode of the storage battery of the automobile, are not easy to loosen when the automobile bumps, and directly sleeved on the cylindrical body with no springs required, internal space of the car charger is saved, production is convenient, and the car charger is more attractive in appearance compared with the existing products.

Description

Onboard charger

Technical field

The utility model relates to a kind of onboard charger.

Background technology

Onboard charger (being called for short " car fills ") is that a kind of automobile storage battery power supply (general 12V or 24V) is converted to can be for the power supply unit of the products such as mobile phone, GPS charging (general 5V).The positive pole that existing car fills is to adopt a five metals spring being located at housing front end central authorities to link to each other with the positive pole of automobile storage battery, and negative pole is by two linking to each other with the automobile storage battery negative pole to a plurality of five metals shell fragments of being located at the housing side.The shortcoming that above-mentioned car fills is that just as easy as rolling off a log and both positive and negative polarity automobile storage battery that car fills when automobile bumpiness gets loose, and contacts badly, and anodal and negative pole takies larger space in addition, so that the interior space of housing is less.

Summary of the invention

The purpose of this utility model is to fill for existing car the problems referred to above of existence, provides a kind of and can both contact with the automobile storage battery both positive and negative polarity good onboard charger when road conditions are bad.

The purpose of this utility model is achieved in that jockey that the utility model comprises housing, is used for connecting with product to be charged, be installed in the housing wiring board and with the both positive and negative polarity of automobile storage battery corresponding positive pole, negative pole respectively, the both positive and negative polarity of described and automobile storage battery respectively corresponding positive pole, negative pole is cylindrical shape, be sleeved on the surface of housing, and be electrically connected with wiring board in the housing.

As preferred version, described jockey is the USB female seat, is installed in the rear end, inside of housing, and it is corresponding with it to be provided with the USB jack at the rear end face of housing.

As preferred version, described jockey be an end with the charging wire of charging inlet, the other end of charging wire is fixedly connected with the rear end of described housing and is electrically connected with wiring board in the housing.

As preferred version, described housing is reached by the cylinder type main body and forms with the front end of main body, protecgulum, the bonnet that the rear end is fixedly connected with respectively, described positive pole is enclosed within on the front portion of cylinder type main body, negative pole is enclosed within on the rear portion of cylinder type main body, offer the groove that passes through for wire at front portion, the rear portion of cylinder type main body, described positive pole, negative pole are electrically connected with wiring board in the housing by wire.

Technique effect of the present utility model is: 1, positive pole of the present utility model, negative pole contact well with the both positive and negative polarity of automobile storage battery, are difficult for getting loose when automobile bumpiness; 2, positive pole of the present utility model, negative pole directly are enclosed within on the cylinder type main body, do not establish spring, have saved the inner space of onboard charger, produce more convenient.It is more attractive in appearance that the utility model and existing product are compared shape.
