Abstract
The utility model relates to a USB charger, and in particular relates to a vehicle-mounted USB charger. The vehicle-mounted USB charger comprises a cigarette lighter plug. The cigarette lighter plug comprises a casing body which is matched with a car power supply jack in shape and a power supply input end at the bottom of the casing body. The power supply input end is connected with a switching circuit board. The switching circuit board is connected with one or more USB interfaces. According to the improvement, the USB interfaces are arranged on the positions, which are away from the bottom, on the casing body; and each USB interface is provided with a baffle which can be pushed and pulled to block or expose the USB interface. When the vehicle-mounted USB charger provided by the utility model is used, a baffle is pulled open, and a USB interface is exposed to be connected with an electronic product for USB charging. When the vehicle-mounted USB charger is not in use, a baffle is pushed, and a USB interface is blocked by a baffle, thus a USB interface is isolated from the outside and is prevented from being corroded or damaged.
Description
Technical field
The utility model relates to a kind of USB charger, especially a kind of vehicle-mounted USB charger.
Background technology
Along with the development of science and technology and the raising of people's living standard, people more and more use some portable digital equipment or electronic products, mobile phone for example, panel computer or GPS etc., development along with this series products, its screen size has the trend that becomes gradually large, and its function is also more and more, brought larger facility for people's work and amusement, but thing followed problem is that the power consumption of product is also increasing, continuation of the journey is also shorter and shorter service time, so usually need to charge to keep the normal use of product, in order to be that some users can come this electronic product is charged with the cigar lighter power supply in the car in car, adapter or the patchcord of some cigar lighter power supply transfer USB interface are arranged on the market now, after being inserted in the cigar lighter power interface in the car, can use USB interface that electronic product is charged, but this type of adapter or patchcord are when idle, USB interface is in for a long time and is exposed in the outer environment, owing to comprising a plurality of contacts for conduction in the USB interface, and fix the carrier of these contacts, long term exposure easily causes oxidation or the damage of these parts outside, thereby cause the inefficacy of USB joint, lose the function of charging.
Summary of the invention
The utility model provides a kind of can be protected the USB joint, itself and external environment condition are isolated when idle vehicle-mounted USB charger.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a cigarette lighter plug, described cigarette lighter plug comprise one with car in the housing that adapts of power device jack shape and the power input of housing bottom, described power input connects a transit line plate, described transit line plate connects one or more USB interface, its improvement is: described USB interface is located on the housing away from the position of bottom, and described USB interface is provided with one and can carries out push-and-pull and block or expose the baffle plate of USB interface.
Preferably, described baffle plate is provided with one or more perforates of pulling open rear aligning USB interface.
Preferably, described housing outer wall is provided with housing is fixed in Clip Reed in the cigar lighter jack.
Preferably, described shell stretches out away from the position of power input, forms an area greater than the end face of outer cover body area of section, and end face is provided with an end cap, and described USB interface is located in the described end face, and described baffle plate is located on the described end cap.
Owing to having adopted said structure, the utility model vehicle-mounted USB charger in use, pull open baffle plate, expose USB interface and can carry out the USB charging by the connecting electronic product, when not using, promote baffle plate, make baffle plate block USB interface, USB interface is isolated from the outside, avoids being subject to corrosion or damage.
Description of drawings
Structural representation when Fig. 1 is the flapper closure of the utility model embodiment;
Fig. 2 is the structural representation of the baffle plate of the utility model embodiment when pulling open.
Embodiment
As depicted in figs. 1 and 2, the vehicle-mounted USB charger of the present embodiment comprises a cigarette lighter plug, described cigarette lighter plug comprise one with car in the housing 1 that adapts of power device jack shape and the power input 2 of housing bottom, described power input 2 connects a transit line plate and (is positioned at enclosure interior, not shown), described transit line plate connects one or more USB interface 3, one or two USB interface is that example illustrates concrete structure among the present embodiment and the figure, described USB interface 3 is located on the housing 1 away from the position of bottom, and described USB interface 3 is provided with one and can carries out push-and-pull and block or expose the baffle plate 4 of USB interface.
When USB interface quantity during greater than one, when for example being two USB interface in the present embodiment, can expose all USB interface when guaranteeing that baffle plate pulls open, be provided with one or more perforates 61 of aiming at USB interface after pulling open at described baffle plate, because the part position of exposing inside of meeting nature after baffle plate pulls open, so when USB interface is set, a USB interface can be located at the position of naturally exposing after baffle plate pulls open, then magnitude setting lacks one perforate than the quantity of USB interface on baffle plate, two USB interface are for example arranged in the present embodiment, a perforate then is set can be satisfied pulling open mouth and expose the purpose of two USB interface, when closing, the position of perforate between two USB interface forms the structure of sealing.
More stable in order to make in the car pad cigar lighter jack of coming in and going out, described housing 1 outer wall is provided with housing is fixed in Clip Reed 5 in the cigar lighter jack.
Because the shape of housing and cigar lighter jack adapts, so the area in its cross section is generally less, can not hold more USB interface, in order to hold more multi-USB interface, in the present embodiment, described shell stretches out away from the position of power input, form an area greater than the end face (end face is not shown among the figure) of outer cover body area of section, end face is provided with an end cap 6, and described USB interface is located in the described end face 6, and described baffle plate 4 is located on the described end cap 6.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
