In the related art, the housing of the optical fiber adapter is a hollow structure, and connecting structures for detachable connection are arranged between the opposite ends of the optical fiber adapter and the optical fiber connector. The connecting structure comprises a clamping arm arranged in the shell and a groove arranged on the shell of the optical fiber connector, wherein after the optical fiber connector is inserted into the shell of the optical fiber adapter, the groove is positioned in the shell and clamped with the free end of the clamping arm so as to fix the optical fiber connector and the optical fiber adapter. When it is desired to separate the fiber optic connector and the fiber optic adapter, the rod prongs of the removal tool are directed through the notches in the housing of the fiber optic connector to the grooves and the latch arms, and then the rod prongs are slid under the latch arms to raise the latch arms and cause the latch arms to clear the grooves, thereby separating the fiber optic connector and the fiber optic adapter. However, since the card arm is located in the housing and the space near the card arm is narrow, the rod-like tip is difficult to insert under the card arm, and the card arm may rub against the housing, which may increase the resistance to separation of the optical fiber connector from the housing, and thus, the difficulty of separation of the optical fiber adapter and the optical fiber connector in the related art is high.

In view of the above, the inventors of the present disclosure provide a connection assembly including an adapter and a connector detachably connected, a separation tool for separating the adapter and the connector, and a cable having the connector. The shell of the connector comprises a cylindrical part, and a first fastening part and a second fastening part which are arranged on the outer surface of the wall of the cylindrical part in an extending mode.

The separation instrument of this disclosure includes main part, inserted part and joint portion, and the first end of inserted part and the first end of joint portion all are connected with the first end fastening of main part.

When the connector and the adapter are butted, the part of the cylindrical part is positioned in the first tubular part, the first clamping part is clamped with the first fastening part to fix the adapter and the connector, and in addition, the second fastening part is exposed out of the first tubular part, in other words, the second fastening part is not wrapped by the first tubular part, so that the second fastening part can be matched with the clamping part of the separation tool.

When the connector and the adapter are separated, the separation tool moves along the axial direction of the first tubular part to enable the insertion part to be inserted into the first tubular part, and the insertion part is located between the first clamping part and the cylindrical part to enable the second end of the first clamping part to move in the direction far away from the cylindrical part, in other words, the first clamping part is elastically deformed, so that the first clamping part is not clamped with the first fastening part any more, and the connector and the adapter can be separated. In addition, the inserting portion enables the first clamping portion to be elastically deformed, the clamping portion is clamped with the second fastening portion, the connector is fixed with the separating tool, the main body portion is pulled to move along the direction far away from the adapter, and the connector is separated from the adapter.

Because first card portion is located first breach, the space that first card portion took place elastic deformation (along the direction that deviates from tube-shape portion) is nearly infinitely large to guarantee that the portion of inserting thoroughly parts first card portion and first fastening portion. In addition, since the insertion portion is located outside the cylindrical portion, the difficulty of using the separation tool is low. In addition, because joint portion and second fastening portion joint, separation tool can drive the connector and keep away from the adapter to keeping away from the in-process, first card portion and first fastening portion part are separately all the time, so set up, can reduce, through separation tool pulling connector and adapter separation, can reduce the separation degree of difficulty of connector and adapter, in addition, can avoid connector, adapter and have the cable damage of connector.
