Embodiment
The PCB loading plate is provided with 4 conductive contacts in a kind of structure of no metal cap USB connector, be respectively power contact and data contact, wherein power contact comprises+5V power contact and earthing contact, data contact comprises that the D+ data-signal gets an electric shock and D-data-signal contact, and no metal cap USB connector of the present invention is based on said structure.
Be illustrated in figure 1 as existing no metal cap USB connector 100, Figure 2 shows that the upper surface 100A of no metal cap USB connector 100,100A is provided with power contact+5V101 at upper surface, earthing contact GND104, data-signal contact D+103 and data-signal contact D-102, Figure 3 shows that the lower surface 100B of no metal cap USB connector 100, conductive contact is not set on lower surface 100B.
Figure 4 shows that a kind of embodiment of no metal cap USB connector 200 easy to use of the present invention, be provided with power contact+5V201 at upper surface 200A as can be seen, earthing contact GND204, data-signal contact D+203 and data-signal contact D-202; Correspondence is provided with power contact+5V211 on lower surface 200B, earthing contact GND214, data-signal contact D+213 and data-signal contact D-212; Wherein power contact 201 is connected with 211 mutual short circuits, and same short circuit mutually connects between other contacts 202 and 212,203 and 213,204 and 214 of upper and lower surface correspondence.
Figure 5 shows that the schematic diagram of the upper surface 200A of no metal cap USB connector 200 easy to use, make 201,202 of upper surface by through hole 210 as can be seen, 211 of the lower surface that 203 and 204 contacts are corresponding with it, 212,213,214 contacts realize electrically connecting.
Figure 6 shows that the schematic diagram of the lower surface 200B of no metal cap USB connector 200 easy to use, as seen each through hole 210 respectively with contact 211,212,213 and 214 electrically connect, so that the contact 211,212,213 on the lower surface 200B or 214 can with the corresponding electric shock 201 that is positioned at upper surface, 202,203 or 204 realize electrically connecting.
Therefore, no matter from which face insert the USB series A female plug seat, on the no metal cap USB connector 200 easy to use+5V, GND, D+ all can be connected with the D-contact is corresponding with corresponding+5V, GND, D+ in the female plug seat with the D-contact.
Figure 7 shows that the USB female plug seat 300 on the main process equipment, metal-back at female plug seat 300 is provided with metallic protrusions 305, the structure of USB female plug seat 300 shown in Figure 8 comprises metal-back 301, the carrying backing plate 303 and on conductive contact, and metallic protrusions 305, described metallic protrusions 305 is in order to prop up no metal cap USB connector 100 or 200, so that do not have metal cap USB connector 100 or 200 and USB series A female plug seat between keep excellent contact, metallic protrusions 305 also can be used for being connected with the earth terminal of main process equipment.
In the USB series A female plug seat 300 shown in Figure 8, except metal-back 301, outside carrying backing plate 303 and the metallic protrusions 305, also comprise power contact+5V311, earthing contact GND314, data-signal contact D+313 and data-signal contact D-312.When as seen not having in the metal cap USB connector 200 insertion USB series A female plug seats 300, no matter adopt which face to peg graft, each contact 311,312 in the female plug seat 300,313,314 all can realize electrically connecting with corresponding power contact on the no metal cap USB connector 200 and data contact.
After no metal cap USB connector 200 inserted in the USB series A female plug seat 300, metallic protrusions 305 can be with the one or more contact short on the connector 200.As there are not 201 ~ 204 contacts on the metal cap connector 200 when 311 ~ 314 contacts on the female plug seat are connected, one or more may the contact with metallic protrusions 305 in 211 ~ 214 contacts on the another side.Therefore, must adopt necessary safeguard measure to prevent contact short, should prevent the short circuit of power contact+5V at least.
Fig. 9 uses two diodes 401,402 in order to prevent that power contact+5V is by metallic protrusions 305 short circuits to Figure 11 shows that. Diode 401 and 402 positive pole link to each other with the power contact 201,211 of no metal cap USB connector 200 respectively, and diode 401 and 402 negative pole are connected in node 1, in node 1 and the usb bus+and the 5V power line links to each other.
Further set forth, when no metal cap USB connector 200 inserts USB series A female plug seat 300, + 5V voltage loads and node 1 via diode 402, power contact+5V201 is in earth potential and is connected with metallic protrusions 305 short circuits, then diode 401 oppositely ends, and what make node 1 can ground short circuit; In like manner, when no metal cap USB connector 200 inserted USB series A female plug seats 300 ,+5V voltage loaded and nodes 1 via diode 401, and diode 402 oppositely ends, and that guarantees node 1 can ground short circuit.
Various forms of diodes or all can be used as diode 401,402 by the triode that uses as diode behind the short circuit and use.Forward voltage drop is lower when selecting diode, can be used as preferred diode as the Xiao Jite diode and uses, in order to reduce by the overall presure drop on 201, the 211 contact postjunctions 1.In addition, node 1 not only can with usb bus in+the 5V power line is connected, a part that also can be used as external equipment directly links to each other with electrically conductive, electrically mark on the wiring board, as flash memory, can be directly and the USB series A female plug seat on the main process equipment peg graft.
Earthing contact 204 in the no metal cap USB connector 200; 214 need not carry out short-circuit protection; and data-signal contact D+/D-(203/213 and 202/212) protection can adopt the guard method that is similar to power contact to carry out short-circuit protection in different embodiment; simple diode or diode apparatus all can be applicable to the protection that data-signal gets an electric shock, as drawing on can using or pulldown network can be guaranteed the stability of signal transmission.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
