Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2 and fig. 3, a novel communication pigtail connects, including connector 1, protective layer 2 and lag 3, the pigtail cable is connected to 1 one end of connector, the connector 1 other end and protective layer 2 are connected, lag 3 is located protective layer 2 and keeps away from the one end of connector 1, lag 3 both sides all are provided with flexible rod 31, the one end that protective layer 2 was kept away from to flexible rod 31 one end connection lag 3, be provided with grafting lug 311 on the outside of

flexible rod

31, 3 outer walls of lag are coaxial to be provided with connects cover 32 soon, connect cover 32 outer wall soon to be equipped with the screw thread, set up the perforation of adaptation grafting lug 311 on the connect cover 32 soon.

In this embodiment, in the process of splicing the optical fiber, the elastic rod 31 is pressed to connect the plug sleeve 32 and the interface in a screwing manner, and then the elastic rod 31 is loosened, so that the plug bump 311 passes through the plug sleeve 32 and is inserted into the adapted interface, thereby improving the firm splicing strength of the spliced optical fiber, and when the optical fiber needs to be pulled out, the elastic rod 31 is pressed to rotate, so that the tail fiber connector can be easily screwed out.
