If the number of the optical fiber adapters A on the communication device is large, the electronic label sleeve D can be sleeved outside the optical fiber connector plug B, and the optical fiber connector plug B of the electronic label sleeve D can be inserted into the optical fiber adapter A. Therefore, the fiber adapter A port matching the fiber connector plug B can be identified according to the correspondence between the preset identification information and the fiber adapter A port.

Since the electronic label sleeve D and the optical fiber connector plug B form a pluggable connection, when the electronic label sleeve D is removed from a fiber connector plug B, the identification information stored in the electronic label sleeve D can be changed. And the electronic label sleeve D after changing the identification information can be sleeved on the other optical fiber connector plug B, thereby realizing the multiplexing of the electronic label sleeve D.

When the converter C shown in FIG. 4 is sleeved outside the fiber connector plug B shown in FIG. 3, as shown in FIG. 5, the first elastic piece 2c disposed on the converter C is located on the outer sheath 2b of the fiber connector plug B. In the upper limiting groove 3b, the first elastic piece 2c is pressed against the first step 4b on the side of the limiting groove 3b. Since the end portion of the outer sheath 2b of the optical fiber connector plug B shown in FIG. 3 is relatively large, the remaining portion is relatively small. Therefore, after the first step 4b on the limiting groove 3b is pressed by the first elastic piece 2c, Will prevent conversion The device C is detached from the fiber connector plug B, so that the converter C is tightly fitted outside the fiber connector plug B by the cooperation of the first elastic piece 2c and the first step 4b. In addition, since the outer sheath 2b of the plug B of the optical fiber connector shown in FIG. 3 and the main body lb are mutually movable, when the converter C is pulled out from the plug B of the optical fiber connector, the converter The first elastic piece 2c on C is flared outward, thereby causing the converter C to be detached from the plug B of the optical fiber connector.

In order to enable the fiber connector plug B of the socket converter C to form a pluggable structure with the port of the fiber optic adapter A, the present invention also provides a further embodiment of the converter C, as shown in FIG.

In the limiting groove 3b on the sleeve 2b, the fourth projection 3d on the electronic label sleeve D is fastened to the first step 4b on the outer sheath 2b and abuts against the third step on the main body lb. Since the end portion of the outer sheath 2b of the optical fiber connector plug B is relatively large, the remaining portion is relatively small, and therefore, the first step 4b prevents the electronic label sleeve D from moving away from the end of the outer sheath 2b, and The three steps prevent the electronic label sleeve D from moving toward the end of the outer sheath 2b, thereby preventing the electronic label sleeve D from coming out of the fiber connector plug B. The electronic label sleeve D and the optical fiber connection are realized by the cooperation of the fifth elastic piece 2d and the fourth protrusion 3d thereon in the electronic label sleeve D with the first step 4b on the outer sheath 2b and the third step on the main body lb.

As can be seen from FIG. 12, the end face of the electronic label sleeve D that is sleeved on the optical fiber connector plug B is in contact with the rear portion of the locking member 2a of the optical fiber adapter A, which in turn causes the electronic connector of the optical fiber connector plug B to be nested. The label set D has been limited. When the optical fiber connector plug B of the electronic label sleeve D is pulled out from the optical fiber adapter A, since the end portion of the outer sheath 2b in the optical fiber connector plug B is relatively large, the remaining portion is relatively small, and therefore, the electronic label The fifth elastic piece 2d on the sleeve D is outwardly deployed to drive the locking member 2a on the optical fiber adapter A to expand outward, so that the locking member 2a on the optical fiber adapter A will be from the main body lb of the optical fiber connector plug B. The third step 5b is disengaged. The optical fiber connector plug B and the optical fiber adapter A of the electronic label sleeve D are sleeved by the cooperation of the locking member 2a of the optical fiber adapter A with the fifth elastic piece 2d on the electronic label sleeve D and the third step 5b of the main body lb.
