Abstract
The utility model discloses a universal serial bus (USB) charging interface which comprises a shell and a bracket, wherein a connecting pin, two contacts and a connecting copper sheet are arranged on the bracket; the two contacts are connected in series at the input end of the USB charging interface and are distributed on two sides of the connecting copper sheet; and when the USB secondary port is connected, the contacts and the connecting copper sheet are connected to form a loop, and the power is supplied to the terminal electrical equipment through the connecting pin. According to the technical scheme, the service life of a voltage transformation module component is prolonged, and the power resources are saved; and moreover, the potential safety hazard caused when the electronic elements are used for a long time and generate heat is reduced, and the using safety in the life is virtually improved; and therefore, the life becomes convenient and safe.
Description
Technical field
The utility model relates to a kind of charging device, relates in particular to a kind of USB charging inlet.
Background technology
Digital product known today all adopts the charging of USB charging inlet charger like mobile phone, digital camera, MP3, MP4 etc.The use of USB charging inlet charger has brought many facilities for our life, and along with the more and more deep every field that is applied to the modern life of development of science and technology.But everybody is when using the charging of USB charging inlet charger, and much human is taken off use with product, and charger is forgotten in supply socket after the product charging is accomplished.Charger has not only been accelerated the aging of components and parts in continuous galvanization, shortened the useful life of components and parts, and wasted electric power resource greatly.In addition, electronic component use for a long time can be distributed a large amount of heat, is easy to cause the generation of accidents such as fire.
Summary of the invention
The utility model provides a kind of intelligently connecting or disconnecting type USB charging inlet to deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of USB charging inlet comprises shell and support, and said support is provided with and connects pin, contact and be connected copper sheet.Said contact quantity is 2, and it is connected on USB charging inlet input, and is distributed in connection copper sheet both sides.Contact forms the loop with being connected after copper sheet is connected, and is the terminal appliance power supply through connecting pin.
As preferably, said contact is " 7 " type structure, and its top extension is positioned at and connects the copper sheet top.When not having the USB rim of the mouth to insert in the USB charging inlet, contact be connected copper sheet and be in released state, power supply is in off-state at this moment; When having the USB rim of the mouth to insert in the USB charging inlet; Said contact top occurs bending and deformation under the active force forward of USB rim of the mouth and contacts with the said copper sheet that is connected; The contact that connects the copper sheet both sides this moment is connected, and USB transformation module gets electric, thereby is the power supply of USB charging inlet; After extracted in the USB rim of the mouth, contact recovered former state and is connected the copper sheet disconnection under the effect of self elastic force, the power supply that has cut off USB transformation module, and the USB charging inlet cuts off the power supply, thereby has realized the intelligently connecting or disconnecting function of USB charging inlet.
As preferably, be provided with insulating trip outside the extension of said contact top.When having the USB rim of the mouth to insert in the USB charging inlet, USB rim of the mouth active force forward acts on the insulating trip of contact top outer, thereby prevents that contact is communicated with the USB rim of the mouth, causes safe handling hidden danger.
Technical scheme according to the utility model; Not only improved the useful life of transformation module components and parts; Practice thrift electric power resource, and reduced electronic component and used the potential safety hazard of generating heat and causing for a long time, improved the fail safe of using in our life virtually; Thereby made things convenient for our life, also safety our life.

Embodiment
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of USB charging inlet comprises shell 1 and support 2, and said support 2 is provided with and connects pin 3, contact 4 and be connected copper sheet 5.Said contact 4 is connected on USB charging inlet input, and said contact 4 is the terminal appliance power supply with being connected formation loop, copper sheet 5 connection back.Said contact 4 is distributed in and connects copper sheet 5 both sides, is " 7 " type structure, and its top extension is positioned at and connects copper sheet 5 tops, and its extension outside, top is provided with insulating trip 6.
When not having the USB rim of the mouth to insert in the USB charging inlet 4, contact 4 be connected copper sheet 5 and be in released state, USB charging inlet 4 is in off-state at this moment; When having the USB rim of the mouth to insert in the USB charging inlet 4; USB rim of the mouth active force forward acts on the insulating trip 6 of contact 4 top outer; Said contact 4 tops occur bending and deformation under the active force forward of USB rim of the mouth and contact with the said copper sheet 5 that is connected, and the contact 4 connections formation loops that connect copper sheet 5 both sides this moment are the terminal appliance power supply.After extracted in the USB rim of the mouth, contact 4 recovered former state and is connected copper sheet 5 disconnections under the effect of self elastic force, cut off USB charging inlet 4 power supplys, thereby realized the intelligently connecting or disconnecting function of USB charging inlet 4.Insulating trip 6 can prevent that contact 4 is communicated with the USB rim of the mouth, causes safe handling hidden danger.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
