Multi-output USB charger

Abstract

The invention relates to the technical field of vehicle-mounted chargers, in particular to a multi-output USB charger which comprises a charging head, a shell, connecting grooves, USB interfaces and anti-falling mechanisms, the charging head is arranged at one end of the outer surface of the shell, and the connecting grooves are formed in the positions, close to the upper end and the lower end, of the side, away from the shell, of the outer surface of the charging head; the USB interfaces are arranged in the two sets of connecting grooves, the anti-falling mechanisms are arranged in the two sets of connecting grooves, each anti-falling mechanism comprises two sets of anti-falling assemblies, and movable grooves are formed in the upper ends and the lower ends of the sides, away from the USB interfaces, of the inner surfaces of the connecting grooves. And the anti-falling assemblies are in one-to-one correspondence with the movable grooves and are arranged in the movable grooves. According to the invention, the two groups of anti-falling assemblies are used for fixing a connecting line matched with the USB interfaces at the same time, and the probability that the connecting line is separated from the USB interfaces due to accidental touch is reduced, so that the attention of a driver during driving is concentrated, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle chargers, in particular to a multi-output USB charger. Background technique [0002] With the popularity of motor vehicles, USB car chargers are also widely used. USB car chargers are usually referred to as USB car chargers. It takes advantage of the versatility of USB and is widely used in various charging interfaces. Combined with the application on cars or motorcycles, the 12VDC and 24VDC on the car are converted into the common 5VDC voltage of USB and various charging appliances. In this way, the standard power supply and USB interface on the car can be used to charge 5VDC electrical appliances. Such as: mobile phones, MP3, navigators, game consoles and other 5VDC electrical appliances; [0003] However, there are still some deficiencies in the existing car chargers. For example, when the driver accidentally touches and squeezes the connecting wire while driving the vehicle, it is easy to ca...

Problems solved by technology

[0003] However, there are still some deficiencies in the existing car chargers. For example, when the driver accidentally touches and squeezes the connecting wire while driving the vehicle, it is easy to cause the USB charger to be separated from the connector of the connecting wire. Only when the connection line is reconnected can it continue to be used. However, reconnecting will affect the driving attention, causing the driver to be inattentive while driving the vehicle, which is very likely to cause a vehicle safety accident, which increases the danger during driving. This problem is more pronounced when driving on a high-speed lane
