Embodiment
The invention provides a kind of USB joint, below in conjunction with accompanying drawing, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, do not limit the present invention.
As shown in Figure 2, embodiments of the invention provide a kind of USB joint, comprising: shell 2, support 3 and circuit board 4; Support 3 is arranged in shell 2, and circuit board 4 is fixed on support 3; Circuit board 4 is provided with the USB contact 41 and USB pad 42 that correspond to each other, often pair of corresponding USB contact 41 is electrically connected with USB pad 42; Wherein, USB contact 41 for external USB equipment interface, USB pad 42 is for being electrically connected the internal circuit of described USB joint with the equipment providing described USB joint, signal processing circuit 43 is provided with, for processing the signal between USB contact 41 and USB pad 42 between USB contact 41 and USB pad 42.
The USB joint that embodiments of the invention provide, circuit board 4 is provided with in the support 3 of shell 2, circuit board 4 is provided with the USB contact 41 for inputing or outputing usb signal, USB pad 42, and circuit board 4 is also provided with signal processing circuit 43, can process the signal of transmission between USB contact 41 and USB pad 42, thus make USB interface under the condition keeping existing profile and volume, there is certain signal processing function, substantially increase integrated level and the performance of USB joint.
Because USB interface is standardized interface, putting in order of its holding wire, power line and earth connection, signal line dimensions spacing etc. all will meet the regulation of relevant criterion, therefore, the setting of the USB contact 41 on circuit board 4 also should meet relevant criterion, specifically, for A type USB joint (for connecting the USB joint of PC end), circuit board 4 is provided with 4 USB contacts, wherein, a USB contact connects power supply, two USB contact connection signals, a USB contact ground.USB pad 42 is corresponding with USB contact 41.Both USB pad 42 and USB contact 41 both can be positioned at the same face of circuit board 4, also can be positioned at the contrary two sides of circuit board 4, if can make this USB joint respectively with described external equipment and described internal circuit interface.
Optionally, USB contact 41 both can for the golden finger plug-in unit be fixed on circuit board 4 also can for being printed on the hard contact on circuit board 4, embodiments of the invention are not construed as limiting this.
Signal processing circuit 43 can carry out different process according to the specific works environment of USB joint or embody rule to signal usually; optionally, signal processing circuit 43 can comprise one or more in following circuit: electrostatic discharge protective circuit, voltage conversion circuit, codan.
Such as, as shown in Figure 3, in one embodiment of the invention, be provided with signal processing circuit 43 between USB contact 41 and USB pad 42, this signal processing circuit 43 comprises electrostatic discharge protective circuit 431, voltage conversion circuit 432, codan 433.Wherein, voltage conversion circuit 432 can realize under the control of control circuit 434 direct voltage liter step-down, such as the 5V direct voltage of input can be converted to 3V or 15V export.Codan 433 by the appropriate design realization of circuit to the suppression of interference, such as, by the suppression of circuit design realization to common mode disturbances of differential configuration, thus can effectively improve the quality of USB signal transmission.And electrostatic discharge protective circuit 431, the ability of the antistatic of USB joint can be strengthened, better protect rear end equipment.
Specifically, USB joint can be electrically connected with providing the internal circuit of the equipment of described USB joint (as USB flash disk) by USB pad 42, and its concrete connected mode is not limit.Such as, in one embodiment of the invention, each signal line of internal circuit or the direct pressure welding of power line are on USB pad 42.Easier in order to make USB joint weld with the circuit of internal circuit, preferably, in another embodiment of the present invention, outward extending protuberance can also be set on USB pad 42, each signal line of internal circuit or power line are welded over the projections, then USB pad 42 is electrically connected by the internal circuit of protuberance with the equipment providing USB joint.This protuberance can be the projection that any metal material is formed, such as, be welded to the steel disc etc. on USB pad.
Optionally, circuit board 4 can be fixedly installed on support 3 in every way.Such as, as shown in Figure 4, support 3 can be provided with groove, circuit board 4 can be fastened in groove, thus is fixed circuit board 4 and supports.The size of groove and particular location can adjust according to parameters such as the shape of circuit board or thickness.Due to circuit board 4 can lay more circuit, therefore effectively optimize the signal quality in USB joint.
Because USB contact 41 and USB pad 42 all arrange (concrete on the circuit board 4, in the embodiment shown in fig. 4, USB contact 41 and USB pad 42 lay respectively at the positive and negative different two sides of circuit board 4, in Fig. 4, only USB contact 41 is visible), therefore, can whether circuit board 4 can be arranged on support 3 according to preset bearing and effectively be connected directly decide USB contact 41 with external USB equipment, because probably cause USB contact 41 also out of position once the installation of circuit board 4 deviate from original position.Occur to prevent above-mentioned situation, circuit board 4 can also be provided with at least one location hole, support 3 is provided with at least one reference column 32, when circuit board 4 is placed in precalculated position, reference column 32 can be located to make circuit board 4 through location hole on support 3.
Although be example object, disclose the preferred embodiments of the present invention, it is also possible for those skilled in the art will recognize various improvement, increase and replacement, and therefore, scope of the present invention should be not limited to above-described embodiment.
