Description

Portable small-size charger

Technical Field

The utility model relates to a charger technical field specifically is a portable little volume charger.

Background

The main types of user contact are the first two. The most sold traveling chargers in the market are various in forms, common duck egg type miniature traveling chargers with low price, common table type card board type chargers and high-grade table type chargers with liquid crystal display are available. As most of mobile phone users are non-professional users, the charger basically has the function of full charge and automatic stop, most of travel charging belongs to the quick charger, and the charging time is about 1-3 hours. A plurality of chargers in the market all adopt microcomputer control by themselves, including some duck egg type miniature traveling chargers with very low prices, the charger is strictly analyzed from a charging circuit, a very small part of the charger can be truly controlled by a microcomputer (single chip microcomputer), the connection part of the existing portable small-volume charger plug and the USB joint is easy to loosen, and the connection position of the charger plug and the USB joint is easy to damage.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a portable little volume charger has solved current portable little volume charger plug and the easy production of USB articulate position and has become flexible, leads to charger plug and USB articulate the position to produce the problem of damage easily from this.

Technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a portable little volume charger, includes the plug, the right side of plug is pegged graft and is had the USB to connect, the right side fixedly connected with wire that USB connects, the right side fixedly connected with sleeve that USB connects, telescopic interior roof fixedly connected with spring, the bottom fixedly connected with stripper plate of spring, the lower fixed surface of stripper plate is connected with the lug, the surface that USB connects is seted up flutedly, the surface of lug and the inside joint of recess.

Furthermore, a movable hole communicated with the interior of the sleeve is formed in the upper surface of the sleeve, and a pull rod is movably connected inside the movable hole.

Furthermore, the bottom end of the pull rod is fixedly connected with the upper surface of the extrusion plate.

Furthermore, the top end of the pull rod is fixedly connected with a pull plate.

The utility model provides a portable little volume charger. The method has the following beneficial effects:

this portable small size charger through the mutually supporting between sleeve, spring, stripper plate, pull rod, arm-tie, activity hole, lug and the recess, reaches and to consolidate between plug and the USB connects, has solved current portable small size charger plug and the USB articulate position and has produced easily not hard up, leads to charger plug and USB articulate position to produce the problem of damage from this easily.
