Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar improvement when intension of the present invention, therefore the present invention is by the restriction of following public specific embodiment.
It should be noted that: magnetic connector also refers to cable switching device, is the electric connecting device that a kind of magnetic force connects.Interface adapter, refers to the adapter in the plug-in type interface for inserting electronic installation, the plug-in type electric connection mode of described plug-in type interface being converted to surface contact electric connection mode.The present invention refers to after magnetic connector is connected with interface adapter, identifies the connection status of magnetic connector and interface adapter and adjusts.
See also Fig. 1 and Fig. 2, what it was respectively the structural representation of contactor and contactor and matrix coordinates figure.Contactor 400 comprises magnetic metal shell 405, multiple spring needle 401 and magnetic part 403.Multiple spring needle 401 to be arranged in magnetic metal shell 405 and to be flexibly set on matrix 500, and it can pop up and downward retraction relative to matrix 500 under external force, to be connected with the power supply in matrix 500 respectively and disconnection.
Refer to Fig. 3, it is the structural representation of interface head, the generally t-shaped and inserted terminal 30 comprising tip side 10 and be electrically connected with tip side 10 of interface head 100.Tip side 10 comprises ferromagnetic metal conductive pane.In use, inserted terminal 30 inserts in the attachment unit interface of electronic installation, and tip side 10 exposes to outside attachment unit interface, to be electrically connected with external equipment (magnetic connector).
In the present invention, magnetic connector comprises contactor 400, and when magnetic connector bag and interface adapter 100 are connected to form, contactor 400 abuts with interface adapter 100.
Refer to Fig. 4, it is the stitch of magnetic connector of the present invention and the diagrams illustrating stitches of interface adapter.The stitch 300 of magnetic connector and the stitch of interface adapter 200 include GND, D+, D-, ACC-ID, VCC.Also being set with external contact in magnetic connector one end is a, b, c, d, e, f, and f contact is the metal shell of magnetic connector.

Ground connection step S01: the metal shell of magnetic connector is connected with default ground wire.That is, to the metal shell input grounding voltage (absolute zero volts) of magnetic connector.
The metal shell of magnetic connector refers to magnetic metal shell 405, and the metal shell of interface adapter refers to the ferromagnetic metal conductive pane of tip side 10.
When magnetic connector is connected with interface adapter 100, magnetic metal shell 405 abuts with the ferromagnetic metal conductive pane of tip side 10, now, as long as to metal shell (magnetic metal shell 405) the input grounding voltage of magnetic connector, the metal shell of interface adapter also correspondence have input earthed voltage.
When metal shell due to interface adapter is communicated with earth terminal, when namely the metal shell of interface adapter have input earthed voltage, ACC-ID stitch just there will be specific waveform signal, i.e. ACC-ID pin output signal.That is, described preset signals is ACC-ID pin output signal.It should be noted that, ACC-ID pin output signal refers to the ACC-ID pin output signal of the lightning connector of apple iPhone.Therefore, after the metal shell ground connection of magnetic connector, the ACC-ID stitch of interface adapter exports ACC-ID pin output signal, and this ACC-ID pin output signal will transfer to the external contact of magnetic connector.
Determining step S02: judge whether the default pin of magnetic connector has preset signals, otherwise oppositely leg signal is exported to the pin of magnetic connector according to current pin numeric order.Such as, described first presets the 4th pin that pin is magnetic connector, and described second presets the second pin that pin is magnetic connector.In the present embodiment, pin is the external contact of magnetic connector.4th pin is the d contact of magnetic connector, and the second pin is the b contact of magnetic connector.Wherein in an embodiment, described determining step also comprises: judge whether the default pin of magnetic connector has preset signals, is, determine magnetic connector and interface adapter exact connect ion, otherwise leg signal inverted sequence is exported to the pin of magnetic connector.Such as, described default pin comprises the first default pin and the second default pin.Described default ground wire comprises first and presets ground wire and the second default ground wire.Such as, described ground connection step specifically comprises the steps: that metal shell and first is preset ground wire to be connected.Such as, described determining step specifically comprises the steps: that detection first is preset pin and whether had preset signals, is then to connect by the positive sequence direction of presetting, otherwise metal shell and the second default ground wire is communicated with.Such as, describedly metal shell and second are preset after ground wire is communicated with step, also there are following steps: detecting second and preset pin and whether have preset signals, is then by the inverted sequence direction connection preset, otherwise cycle detection.
Be specially: magnetic connector (wire and cable connector) starts once being energized to carry out following action: metal shell and first is preset ground wire and is communicated with, and then detect second preset pin whether have preset signals, then connect by the positive sequence direction of presetting, otherwise metal shell and first is preset ground wire be communicated with, and then detect second preset pin whether have signal, be then by preset inverted sequence direction connect, if still do not had, be then recycled to metal shell and first preset ground wire be communicated with.If any not detecting signal then cycle detection all the time always.
The described pin oppositely leg signal being exported to magnetic connector according to current pin numeric order is specially: during initial condition, stitch GND, D+, D-, ACC-ID and VCC of the stitch 300 of magnetic connector and the external contact a of magnetic connector, b, c, d, e one_to_one corresponding, namely GND and a is corresponding, D+ and b is corresponding, D-and c is corresponding, ACC-ID and d is corresponding, and VCC and e is corresponding, and f is the metal shell contact of magnetic connector.After order oppositely exports, namely GND and e is corresponding, and D+ and d is corresponding, and D-and c is corresponding, and ACC-ID and b is corresponding, and VCC and a is corresponding.
Such as, the first default ground wire is connected with GND.Such as, the second default ground wire is connected with GND.
Refer to Fig. 6, now with a specific embodiment, described determining step S02 is described further: the stitch GND of setting magnetic connector be G1, D+ is G2, D-be G3, ACC-ID be G4, VCC is G5, the GND of the stitch of interface adapter is M1, D+ be M2, D-be M3, ACC-ID be M4, VCC is M5, metallic conduction shell is M6.
Be specially: stitch a is communicated with stitch f, detect stitch d and whether be communicated with the ACC-ID stitch of interface adapter, if stitch d is communicated with the ACC-ID stitch of interface adapter, then stitch a is linked G1, stitch b links G2, and stitch c links G3, stitch d links G4, and stitch e links G5.If stitch d is not communicated with the ACC-ID stitch of interface adapter, then stitch e is communicated with stitch f.
After stitch e is communicated with stitch f, detects stitch b and whether be communicated with the ACC-ID stitch of interface adapter, if stitch b is communicated with the ACC-ID stitch of interface adapter, then stitch a is linked G5, stitch b links G4, and stitch c links G3, stitch d links G2, and stitch e links G1.
Thus, ensure that M1 and G1 is communicated with, M2 and G2, M3 and G3 are communicated with, M4 and G4 is communicated with, M5 and G5 is communicated with.
