Description
Technical field
The utility model relates to a kind of interface convertor, the interface convertor of a particularly a kind of end grafting computer and other end grafting computer periphery serial equipment.
Background technology
The interface convertor that existing market is sold generally is that USB changes RS-232 (serial ports) transducer, and this known interface convertor is that the end at a cable is provided with the USB joint, is used to connect computer; And the other end is provided with RS-232 (serial ports), and the bolt-lock that is used to peg graft can carry out transfer of data at computer periphery serial equipment.As everyone knows, the volume ratio of the RS-232 of this interface convertor (serial ports) is bigger, inevitable many consumption of raw material, thus increasing production cost, one of reason that volume ratio is bigger is that the PCB wiring board in the RS-232 (serial ports) has taken certain volume.
Summary of the invention:
The technical problems to be solved in the utility model provides the small and exquisite interface convertor of a kind of volume, PCB wiring board in the RS-232 (serial ports) is transferred in the USB plug, both can dwindle the volume of RS-232 (serial ports), can make full use of the space in the USB plug again.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of interface convertor, comprise a cable and USB tip side thereof and RS-232 serial ports end, this USB tip side has the interface of the local parcel of garment bag, in the interface of the local parcel of this garment bag, the PCB wiring board is installed, this PCB wiring board is provided with the circuit that is made of electronic devices and components, one end of this circuit cooperates formation USB joint with the interface of the local parcel of this garment bag, and the other end of this circuit is connected with RS-232 serial ports end by cable.
As preferably, be provided with fixedly plug and cover body, the fixing glue fork clip is on the PCB wiring board, then together intercalation in iron-clad, cover body is buckled in above the iron-clad opened portion, above-mentioned iron-clad, fixedly plug, PCB wiring board, cover body injecting glue are fixing constitutes interface, and this interface is by the local parcel of garment bag, and expose outside the garment bag Plug Division of iron-clad.
As preferably, the circuit that is made of electronic devices and components on this PCB wiring board comprises chip FT232 and SP3232, four pin connector JP2, the CON4 of chip FT232 are connected with USB, and five pin connector JP1, the JP2 of chip SP3232 are connected with RS-232 serial ports end by cable.
Because the utility model interface convertor is transferred to the PCB wiring board in the RS-232 (serial ports) in the USB plug, has both dwindled the volume of RS-232 (serial ports), can make full use of the space in the USB plug again.Compare with existing product, because the RS-232 volume dwindles greatly, can save material and reduce cost, manufacturer and consumer are beneficial to.
