The utility model content

In view of this, the utility model provides a kind of USB device, neither needs special USB head, saves cost, can make the compactness that is connected of USB device and computer USB interface simultaneously again, has avoided the easy problem of short-circuit of golden finger.

For achieving the above object, the utility model embodiment provides a kind of USB device, comprises housing, is placed on the pcb board in the described housing, and described pcb board comprises the golden finger structure, it is characterized in that, described USB device also comprises:

USB metal cap is fastened on the described housing, and surrounds the rectangular structure that described golden finger and described housing are positioned at described golden finger bottom, to constitute standard USB head jointly with described golden finger and described rectangular structure.

USB device of the present utility model does not need special USB head, has saved USB installation time, has reduced cost.In addition, because USB metal cap and housing are connected fastening, and utilize USB metal cap to coat described golden finger, not only make the compactness that is connected of described USB device and computer USB interface, avoided the easy problem of short-circuit of golden finger, can overcome simultaneously since golden finger exposed outside easily dirty, the perishable defective of the equipment that brings.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

With reference to Fig. 1, be the structural representation of the embodiment of a kind of USB device of the present utility model; As shown in Figure 1, described USB device comprises: USB metal cap 1 and housing 2.

A described USB metal cap 1 is fastened on the described housing 2, and surrounds the rectangular structure that described golden finger and described housing 2 are positioned at described golden finger bottom, to constitute standard USB head jointly with described golden finger and described rectangular structure.

In the specific implementation, described housing 2 can be plastic casing, and it comprises dismountable two parts up and down, described two parts up and down constitute the accommodation space of housing 2, are used for the ccontaining pcb board that comprises the golden finger structure, wherein, particularly, described golden finger can be engraved on the described pcb board.A described USB metal cap is socketed in described golden finger and described housing 2 is positioned on the rectangular structure of described golden finger bottom, to constitute standard USB head jointly with described golden finger and described rectangular structure.

The utility model can be saved USB installation time, reduces cost of labor, and reduces USB cost, and profile is the same with generic USB equipment, makes to be connected compactness with computer USB interface, has avoided the easy problem of short-circuit of golden finger.

With reference to Fig. 2, be USB the metal cap cross section structure synoptic diagram of the embodiment of a kind of USB device of the utility model; A USB embodiment illustrated in fig. 2 metal cap can be the metal cap of the USB in embodiment illustrated in fig. 11; As shown in Figure 2, a described USB metal cap 1 comprises: buckle 3.

In the specific implementation, the inside surface of a described USB metal cap 1 is provided with buckle 3, and a described USB metal cap 1 links fastening by described buckle 3 and described housing 2.In the specific implementation, the cross section of described buckle 3 can for shapes such as polygon, ellipse, circle any one or multiple, and described buckle 3 can have one or more.

Present embodiment passes through in the housing binding of the buckle structure of USB metal cap setting and USB device fastening, has both saved USB installation time, reduces the cost of manufacture of USB device again.

With reference to Fig. 3, be the shell structure synoptic diagram of the embodiment of a kind of USB device of the utility model; The described housing of Fig. 3 can be the housing in embodiment illustrated in fig. 12; As shown in Figure 3, described housing 2 comprises:
