Detailed Description

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

Referring to fig. 1 and 2, an embodiment of the present invention is suitable for an optical fiber connector 9, the optical fiber connector includes a body unit 1, a dustproof unit 2 connected to the body unit 1, and a jacket unit 3 located outside the body unit 1. In this embodiment, the case of adapting a connector of MPO specification to an optical fiber cable will be described.

The body unit 1 includes a flange ring 11, a connector end piece 12 axially extending integrally from the flange ring 11 and adapted to be plugged with the optical fiber connector 9, and a plug end piece 13 integrally extending from the flange ring 11 in a direction opposite to the connector end piece 12. Wherein the connector end piece 12 is adapted to the specification of the optical fiber connector 9 and has an outer surface 121 formed with an external thread; the plug end piece 13 is primarily adapted to the cable plug format and has an outer circumferential surface 131 formed with a recess 138 and defining an inner space 130 with an opening 139.

The dust-proof unit 2 is detachably connected to the plug end piece 13 of the body unit 1, and includes a dust-proof cover 21 having an inner annular surface 211, a pull ring 22 connected to an end of the dust-proof cover 21 away from the body unit 1, a sealing sheet 23 disposed in the dust-proof cover 21 and used for sealing the opening 139, and a C-shaped connection ring 28 protruding from the inner annular surface 211 and used for being disposed in the concave connection groove 138 to fix the dust-proof cover 21 to the plug end piece 13. By the mechanism of receiving the C-ring 28 in the groove 318, the dust-proof unit 2 can be easily connected to the plug end piece 13 when necessary. When the dust-proof unit 2 is connected to the plug-in connector 13, in addition to the blocking function of the dust-proof sleeve 21, in order to further prevent dust contamination, the sealing sheet 23 is made of an elastic material, so that when the dust-proof sleeve 21 is fastened to the plug-in connector 13, the sealing sheet is pressed to tightly close the opening 139 of the plug-in connector 13, thereby completely blocking dust from entering the inner space 130 through the opening 139.

Referring to fig. 2 and 3, the outer sleeve unit 3 includes a sleeve 31 sleeved on the body unit 1, and a sealing ring 32 abutting against the sleeve 31 and the flange ring 11. The sleeve 31 has an inner surface 311 formed with inner threads for being screwed with the outer threads, and the sleeve 31 can be sleeved on the body unit 1 and abut against the sealing ring 32 from both sides with the flange ring 11 of the body unit 1 through mutual screwing of the inner threads and the outer threads, thereby further achieving the dustproof effect.

The body unit 1 of the present embodiment is designed to be integrally formed, and is matched with the connector terminal 12 for plugging the optical fiber connector 9 and the plug terminal 13 for plugging the cable connector, i.e. no additional assembling operation is required, and compared with a two-piece design that is re-assembled according to different specifications of two sides, the necessary assembling steps are omitted, thereby improving the efficiency of performing the wiring operation.

Referring to fig. 4 in conjunction with fig. 3, it is to be particularly noted that when the wiring is connected to a wiring tube 81 using the present embodiment, the dust-proof unit 2 can be assembled to the body unit 1, and a pulling rope 82 is fixed to the pulling ring 22 of the dust-proof unit 2. As long as the pulling rope 82 is inserted into the other end of the wiring tube 81, the pulling rope 82 can be easily pulled along the wiring tube 81, thereby quickly disposing the circuit in the wiring tube 81. Of course, when the present embodiment is located in the wiring duct 81, the dust-proof unit 2 can prevent dust from entering the inner space 130 of the plug end piece 13, ensuring that each contact of the line is not contaminated by foreign matters.
