Abstract
The utility model relates to a rear line earthing device, which comprises a copper foil, an earthing piece and screw holes, and is characterized in that a USB interface is tightly connected with the earthing piece through the copper foil, and the sides of the earthing piece are connected with a plurality of screw holes. The utility model has the technical effects that the USB interface is connected with earthing lines of an inner shell and an outer shell of a case, so that interference signals generated by the outside are shielded to the outside of the interface so as to achieve the purposes of high-speed and efficient data transmission.
Description
Technical field
The utility model relates to a kind of earthing device, relates in particular to a kind of rearmounted line earthing device.
Background technology
Along with development of science and technology, people are more and more higher for the rate request of transfer of data, existing generic USB interface, earthing device mainly is after switching on by the interior mainboard ground connection copper sheet of materials such as braiding and ground wire in USB iron-clad and the wire rod and cabinet interference signal to be shielded from the product outside, thereby reach the ground connection purpose, most of USB iron-clads contact insufficient with casing, shield effectiveness is relatively poor.Present technique is fixed USB interface and cabinet panel by screw, USB interface also fully contacts with cabinet panel is fixing, to reach good shield effectiveness.
Summary of the invention
The purpose of this utility model is to provide a kind of rearmounted line earthing device, and earthing device closely contacts with the cabinet iron-clad, to reach the purpose of effective transmission static.
The utility model is achieved like this, it comprises Copper Foil, ground strip, screw hole, it is characterized in that USB interface passes through Copper Foil and closely connect ground strip, the side of described ground strip is connected with several screw holes.
Technique effect of the present utility model is: USB interface links to each other with cabinet inside and outside shell earth connection, and the interference signal that the external world is produced is shielded from the interface outside, to reach at a high speed, effectively transmits the purpose of data.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, USB interface 4 closely connects ground strip 2 by Copper Foil 1, thereby ground strip is fully contacted with USB interface, and to reach the purpose of effective conduction, the side of described ground strip 3 is connected with several screw holes 3 and wraps up with plastic cement, be fixed on the cabinet panel with the M3 screw then, in the assembling process, can closely fix with casing by increasing the lock screw, earthing device is closely contacted, to reach the purpose of effective transmission static with the cabinet iron-clad.
