Abstract
The utility model pertains to the technical field of electronic products, and particularly relates to a vehicle-mounted dual-port USB charger. The vehicle-mounted dual-port USB charger comprises a housing, and a charging circuit board assembly installed in the housing. The housing comprises an upper housing, a lower housing, and a rear cover. The front end of the housing is installed with a first position limiting ring and provided with a first contact passing through the first position limiting ring. Two sides of the front end of the housing are provided with a second position limiting ring respectively and provided with second contacts passing through the second position limiting rings. The charging circuit board assembly comprises a charging circuit board. The front end of the charging circuit board is provided with a stop block. The front end of the stop block is provided with a first spring which is pressed against the first contact, and two sides of the stop block are provided with second springs which are pressed against the second contacts respectively. The rear end of the charging circuit board is provided with two USB connection ports, and two USB windows are formed in the rear cover correspondingly. The periphery of each USB connection port is further provided with a locating ring which is fixed in the hosuing at the rear end portion. The locating ring is further provided with an inner flange for being bonded with the rear cover. According to the utility model, the pull and plug resistance performance can be greatly improved, and the service life of the vehicle-mounted dual-port USB charger can be prolonged.
Description
Technical field:
The utility model belongs to technical field of electronic products, refers in particular to a kind of vehicle-mounted dual-port USB charger.
Background technology:
The motor contact that existing car fills the both sides, Plug Division is generally spring-piece type, and this spring-piece type contact is along with access times increases, and elasticity reduces very fast, therefore easily causes with the grafting of vehicle power output port unstablely, and impact is used; In addition, most cars fill and generally only have a USB output port, can not give two electronic product chargings simultaneously, and general only the dependence with the welding of wiring board of USB port located, then without other ruggedized construction, therefore the anti-plug of USB port is not good, easily gets loose, and useful life is short.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of outward appearance novelty, the more firm vehicle-mounted dual-port USB charger of structure are provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of vehicle-mounted dual-port USB charger, comprise shell and charging circuit board component within it is installed, described shell comprises upper shell, lower house and bonnet, the front end of described shell is equipped with the first spacing collar and is provided with the first contact passed, and the front end both sides are respectively equipped with the second spacing collar and are provided with the second contact passed; Described charging circuit board component comprises the charging circuit plate, at the front end of charging circuit plate, one block is set, and the block front end is provided with first spring of conflicting with the first contact, and both sides are respectively equipped with second spring of conflicting with the second contact; The rear end of described charging circuit plate is provided with two usb connecting ports, correspondence is provided with two USB windows on bonnet, and described usb connecting port periphery also is provided with a locating ring, fixing rearward end in the enclosure, also be provided with on this locating ring for the inward flange with the bonnet bonding.
The utility model car fills the electrode contact blade that the car of pegging graft with the automobile power source output port fills the front end both sides and adopts rounded contact to coordinate the mode of spring, and more existing spring-piece type contact contact performance is more stable; Simultaneously, the utlity model has two output ports arranged side by side, more convenient use; And in the utility model, the usb connecting port periphery also is provided with locating ring it is reinforced to location, its anti-plug performance is significantly promoted, extended useful life.
The accompanying drawing explanation:
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model.
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As shown in Fig. 1～Fig. 2, a kind of vehicle-mounted dual-port USB charger described in the utility model, comprise shell 1 and charging circuit board component 2 within it is installed, shell 1 front end is cylindric, be convenient to car on output port of power source peg graft, rear end is large than front end, in order to there is sufficient space that other assemblies are set.Described shell 1 comprises upper shell 11, lower house 12 and bonnet 13, and the front end of described cylindrical shell 1 is equipped with the first spacing collar 31 and is provided with the first contact 32 passed, and the front end both sides are respectively equipped with the second spacing collar 33 and are provided with the second contact 34 passed; Described charging circuit board component 2 comprises charging circuit plate 21, at the front end of charging circuit plate 21, a block 22 is set, and block 22 front ends are provided with first spring 221 of conflicting with the first contact 32, and both sides are respectively equipped with second spring 222 of conflicting with the second contact 34; The rear end of described charging circuit plate 21 is provided with two usb connecting ports 23, correspondence is provided with two USB windows 131 on bonnet 13, and described usb connecting port 23 peripheries also are provided with a locating ring 14, be fixed on the rearward end in cylindrical shell 1, also be provided with on this locating ring 14 for the inward flange 141 with bonnet 13 bondings.
The utility model car fills the electrode contact blade that the car of pegging graft with the automobile power source output port fills the front end both sides and adopts rounded contact to coordinate the mode of spring, and more existing spring-piece type contact contact performance is more stable; Simultaneously, the utlity model has two output ports arranged side by side, more convenient use; And in the utility model, the usb connecting port periphery also is provided with locating ring it is reinforced to location, its anti-plug performance is significantly promoted, extended useful life.
