Shielding tail cover

Abstract

The invention discloses a shielding tail cover. The shielding tail cover comprises a bolt, a tail cover shell, a set screw, a tail clamp and a threaded sleeve. The structure of the tail cover shell, the tail clamp and the threaded sleeve is adopted; the shielding tail cover can be used for connecting a shielding layer of a cable, and can also be used for connecting an additional shielding layer ofthe cable. The shielding layer is fixedly connected through a corrugated surface by adopting the tail cover shell and the tail clamp, so the problem of unified external shielding of a plurality of cables is solved; and the tail cover shell is fixedly connected with the tail end of a connector, so external force borne by the cable is transmitted to the tail cover shell through the shielding layerand then transmitted to the connector through the tail cover shell, stress of a connection point of the cable and the terminal is relieved and eliminated, alternating stress borne by the cable at thetail end of the connector is buffered. The shielding tail cover has the advantages of being simple in structure, convenient to use, reliable in connection and good in shielding effect.

Problems solved by technology

In the process of applying the above technology, the termination technology of the cable and the shielding layer and the connector tail end has not been well resolved. In the equipment of the prior art, the shielded connector is used to match the shielded cable, and the cable shielding layer adopts a common tail. The existing problem is that not only the wire clamp cannot achieve good grounding, but also the clamping force of the cable shielding layer is not enough, the shielding layer comes out, the shielding performance is affected, and it cannot solve the problem of multiple cables uniformly shielding the outside ; There is also a copper net on the shielding layer to clamp the cable with the clamp. The problem is that the cable connected by this connection method will not only be clamped by the clamp, but the clamping force will be directly pressed to the shielding layer through the copper net. , and then pressed to the cable under the shielding layer, causing the cable to be damaged, and the cable clamping force cannot be controlled. If it is loose, it is easy to cause the cable to come out. If it is tight, it is inevitable that the long external cable of the device will be dragged and trampled during use. , this phenomenon causes the cable to produce bending alternating stress at the end of the connector, which makes the phenomenon of cable damage and root fracture more and more serious, especially for high-speed and high-frequency applications, which seriously affects its high-speed and high-frequency performance, resulting in its function failure
