Abstract

PURPOSE:To obtain a connector by which sure coupling is attained and there is not a fear of loss of a dust-proof cover, by supporting the dust-proof cover on an adapter and using the dust-proof cover to lock a lever when the dust-proof cover is opened. CONSTITUTION:When an end part 35a of a plug 23 is inserted to a hole 25 of an adapter 22, a hole 38 of a detaining lever 37 is engaged with a claw 28 of the adapter 22. When a dust-proof cover 31 is turned to engage a projecting part 32 with a notch 29 of a housing 24, the front end of a rear wall 31c of the dust-proof cover 31 is arranged near the front end of the detaining lever 37, and the detaining lever 37 is not released from the claw 28 of the adapter 22. In case of detachment of a connector 21, the dust-proof cover 31 is guided inward obliquely by a long hole 34 by pressing the dust-proof cover 31 inward, and the projecting part 32 is disengaged from the notch 29, and the dust-proof cover 31 is turned inward. Thus, the front end of the rear wall 31c of the dust- proof cover 31 is sufficiently separated from the front end of the detaining lever 37.

。FIG. 4 shows a conventional optical fiber connector that satisfies these requirements. In this connector 1, a sleeve 4 is loosely fitted into the housing 3 of the plug 2, and a female thread 4a is formed on the inner peripheral surface of the sleeve 4.
A male thread 6a is attached to the outer peripheral surface of the housing 6 in the adapter 5.
The plug 2 and the adapter 5 are reliably connected by forming a sleeve and screwing the sleeve into the housing synchronizer of the adapter 5 when the plug 2 is inserted into the adapter 5.

着される。On the other hand, in optical fiber connectors, in order to prevent connection loss as much as possible, the end face of the ferrule must be cleaned when connecting the plug and adapter. However, as shown in FIG. 4, the ferrule A on the adapter 5 side is located inside the housing synchronizer and is surrounded by the sleeve 13, so it is extremely difficult to clean the end face of the ferrule. Therefore, a dustproof cover is fitted into the plug insertion opening of the adapter of the optical fiber connector.

に近接して位置する。When the end 35a of the plug 23 is inserted into the hole 25 of the adapter 22 in the state shown in FIG. The locking lever 37 is fitted into the locking lever 37 and comes into close contact with a ferrule on the side of the adapter 22 (not shown), and at the same time, the hole 38 of the locking lever 37 engages with the claw 33 of the adapter 22. Next, rotate the dustproof cover 31 and insert the protrusion 32 into the notch 2 of the housing 24.
9. Then, the back wall 31C of the dustproof cover 31
The tip is located close to the tip of the locking lever 37, as shown in FIG.

らはずれることはない。In the connector 21 in such a state, the locking lever 3
7, the hole 38 of the locking lever 37 engages the claw 28.
When the locking lever 37 moves in the direction away from the dust cover 31, the tip of the locking lever 37 hits the tip of the back wall 31C of the dustproof cover 31. However, since the convex portion 32 of the dustproof cover 31 engages with the notch 29 of the housing 24 and movement is restricted by the notch 29, the tip of the locking lever 37 that hits the tip of the back wall 31c of the dustproof cover 31 , whose movement is regulated there. Therefore, the locking lever 37 does not come off the claw 28 of the adapter 24.

２の爪２８からはずすことができる。In order to separate the connector 21 in the state shown in FIG. 2, first push the dustproof cover 31 inward.
As shown in the figure, the convex portion 32 is removed from the notch 29, and then the dustproof cover 31 is rotated inward. As a result, the tip of the back wall 31c of the dustproof cover 31 is attached to the locking lever 3.
Stay far enough away from the tip of 7. Therefore, when the locking lever 37 is operated, the hole 38 of the locking lever 37 is opened to the adapter 2.
It can be removed from the claw 28 of No. 2.
