Embodiment
The whole world in 2012 the phone-charger specification of will seeking unity of action is Micro USB, and electric connector of the present utility model is to be applied to the mobile phone charger, is compatible with Micro USB standard, and the Micro USB external electric connector of can pegging graft.
Consult Figure 1 and Figure 2 the utility model first embodiment schematic diagram, the electric connector of present embodiment preferably comprises: a terminal base 200, one first switch terminal 311, a second switch terminal 312, two power supply terminals 410/420, a trip 500, a supply control unit 600.
But first switch terminal 311 of aforementioned fixation and the second switch terminal 312 of elasticity start constitute one group and detect the loop, and when second switch terminal 312 was positioned at de-energized, second switch terminal 312 contacted and conducting with first switch terminal 311; When the second switch terminal was positioned at the power supply position, the second switch terminal separated and not conducting with first switch terminal.
Consult Fig. 3 and Fig. 4, the electric connector of the present utility model Micro USB external electric connector that is applied to peg graft, Micro USB external electric connector has a plurality of terminals 30, and part is embedded in the tongue 20.Tongue 20 is outer around being covered with an iron-clad 10, and during grafting, aforesaid trip 500 promptly is fastened in iron-clad 10.
Consult Fig. 2 and Fig. 3, when Micro USB external electric connector did not insert, second switch terminal 312 was positioned at de-energized and contacts first switch terminal 311 and the conducting.When supply control unit 600 sensings win switch terminal 311 and 312 conductings of second switch terminal, supply control unit 600 is control transformer 700 outages and voltage source is not provided.
Consult Fig. 2 and Fig. 4, when Micro USB external electric connector inserts, Micro USB external electric connector tongue 20 along terminal groove 230 outer rims move and oppress second switch terminal 312 and in terminal groove 230, move to the power supply position, the switch terminal 311 of winning is separated and not conducting with second switch terminal 312.When supply control unit 600 sensings win switch terminal 321 and the 322 not conductings of second switch terminal, supply control unit 600 is that control transformer 700 provides voltage source.Because tongue 20 surfaces of Micro USB external electric connector are provided with several barriers 21, MicroUSB external electric bonder terminal 30 exposes to heavy being located between two barriers 21 of part of tongue 20, barrier 21 can prevent the outside connector terminals 30 contact second switch terminals 312 of Micro USB when Micro USB external electric connector inserts, and makes that only power supply terminal 410/420 can contact Micro USB external electric bonder terminal 30.
