Multipurpose fiber-optic connector and fiber-optic adapter

A multipurpose fiber-optic connector, comprising:

• a tube, a detachable fastener, a connecting member and a boot, wherein
• a cavity of the tube runs through a first end and a second end of the tube in an axial direction, the cavity being used for a fiber-optic cable to pass through;
• the detachable fastener is a one-piece component formed as a single layer, the detachable fastener is capable of being sleeved on the tube from the first end, and is slidable back and forth between the first end and the second end of the tube, but is incapable of reaching the second end;
• one end of the detachable fastener is provided with a first thread, an other end of the detachable fastener is provided with a snap-in portion, both of the first thread and the snap-in portion are formed as undetachable portions of the single layer, and when the other end of the detachable fastener is inserted into a fiber-optic adapter, the snap-in portion is snapped in a recess of the fiber-optic adapter to connect the detachable fastener and the fiber-optic adapter;
• the connecting member is a one piece component, the connecting member is sleeved on the tube from the second end of the tube, and is slidable back and forth between the first end and the second end of the tube, but is incapable of reaching the first end;
• a second thread is provided on the connecting member and engaged with the first thread, and the detachable fastener is fixedly sleeved on the tube after the second thread is engaged with the first thread;
• wherein a first preset distance is defined between the connecting member and the first end, and a second preset distance is defined between the detachable fastener and the second end, such that the detachable fastener is incapable of reaching the second end, and the connecting member is incapable of reaching the first end;
• wherein the detachable fastener is detachably connected to the connecting member by means of the first thread such that the detachable fastener is replaceable with another fastener adapted to another fiber-optic adapter so as to be adapted to the another fiber-optic adapter;
• the boot is detachably connected to the second end of the tube, and the boot is of a hollow structure for the fiber-optic cable to pass through;
• and
• after the connecting member is sleeved on the tube and positioned in place ready to be engaged with the detachable fastener, the connecting member is slidable relative to the tube and the boot mounted on the tube.
