FIBER OPTIC CONNECTOR WITH SHUTTER

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Chinese Patent Application No. 201110286534.1 filed on September 23, 2011 in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a fiber optic connector, more particularly, relates to a plug fiber optic connector having a shutter that can be automatically opened and closed in use.

Description of the Related Art

With a development of fiber to the home (FTTH), in a fiber net, it often needs to connect fibers together. For example, one way of connecting fibers is to directly insert a ferrule of a fiber optic connector disposed at a front end of a fiber into an adapter. The fiber optic connector and the adapter can be simply assembled and disassembled by this connection way, and it is easier and more convenient than other connection ways, for example, soldering.

However, during inserting the fiber optic connector into the adapter, for effectively ensuring the performance of the connected fibers, it needs to protect the ferrule of the fiber optic connector, so that a bared front end surface of the fiber in the ferrule is protected from dust, moisture, or being touched by a hand. Furthermore, during the fiber transmitting a light, if eyes of an operator are exposed to the light emitted from the bared front end surface of the fiber in the ferrule for a long time, it produces a bad influence on the operator. Specially, with the development of fiber to the home, it is necessary to improve the safety of the fiber optic connector for protecting users. In the prior art, a cover is provided on the front end surface of the fiber in the fiber optic connector and is opened when inserting the fiber optic connector into the adapter. For example, a Chinese patent application No. CN1315007A discloses an assembly of a fiber optic connector and an adapter, in which the fiber optic connector has a cover on its housing. The cover is turnable between an opened position and a closed position to expose and shield the fiber in the fiber optic connector. The fiber optic connector has a longitudinal guide member that is configured to mate with a longitudinal guide member of the adapter to align the fiber optic connector with the adapter and guide the fiber optic connector into the adapter. A cam pin mounted on the adapter is fitted in a cam groove in the cover so that the cover is pushed to the opened position when the fiber optic connector is inserted into the adapter. A spring mechanism is provided to press the cover toward the closed position.

However, the adapter is specially made for the fiber optic connector in the Chinese patent application No. CN1315007A, and a standard adapter is not adapted to the fiber optic connector. Accordingly, it is inconvenient for users and increases the cost.

In addition, a Chinese patent No. CN100437178C discloses another fiber optic connector that can be adapted to the standard adapter. The fiber optic connector comprises at least one ferrule frame and a griping member. The gripping member comprises an inner cylinder and an outer cylinder and is movable between a withdrawn retracted state and an extended state. A shutter is provided on a front end of the inner cylinder. In the extended state, the shutter is arranged to a closed position where the front end of the inner cylinder is closed by the shutter. In the retracted state, the shutter is arranged to an opened position where the front end of the inner cylinder is opened by the shutter. An actuation plate is supported on an inside of the shutter and inclined along the shutter. A front end of the actuation plate is in contact with the shutter. A bias support device presses the shutter to position the shutter in the closed position. With a movement of the inner cylinder relative to the ferrule frame from the extended state to the retracted state, the shutter is moved from the closed position to the opened position. The gripping member is shaped to be adapted to the adapter and engaged with the adapter by snapping to form an optical coupling. A releasing member is provided on a periphery of the outer cylinder to disengage the gripping member and the adapter.

However, the fiber optic connector comprising the inner cylinder and the outer cylinder is complicated in the structure, and it increases the length of the fiber optic connector. Furthermore, it needs to release the shutter by hand, and the shutter may be easily fallen off the fiber optic connector.

Fig. l is an illustrative perspective view of a fiber optic connector 100 and a corresponding adapter 200 according to an exemplary embodiment of the present invention, in which the fiber optic connector 100 is separate from the adapter 200; Fig.5 is an illustrative exploded view of the fiber optic connector 100, when seeing from the its top, according to the exemplary embodiment of the present invention; Fig.7 is a section cross view of the fiber optic connector 100 according to the exemplary embodiment of the present invention.

As shown in Fig.l, Fig.5 and Fig.7, the fiber optic connector 100 mainly comprises a housing 101, an optical fiber alignment device 104, a sliding mechanism 106, a shutter 103 and an elastic mechanism 102.

As shown in Fig.7, the optical fiber alignment device 104 is provided in the housing 101. The optical fiber alignment device 104 has a ferrule 1041 received therein. The ferrule 1041 is formed with an alignment hole in which an optical fiber to be connected is received. An end of the ferrule 1041 is protruded toward the adapter 200 so as to align with and abut against another optical fiber alignment device (not shown) provided in the adapter 200.

Referring to Fig. l, the sliding mechanism 106 is provided on the housing 101 and is slidable in a front-rear direction of the housing 101. In the illustrative embodiments, the adapter 200 is located in front of the fiber optic connector 100 in the front-rear direction.

In the exemplary embodiment shown in Fig. l, the sliding mechanism 106 is configured to be a sliding sleeve slidably fitted on the housing 101. Although it is not shown, the sliding sleeve 106 and the housing 101 may be slidably fitted with each other by, for example, a sliding rail and a guiding groove formed thereon or any other proper means.

As shown in Fig.l, Fig.5 and Fig.7, an opening 1061 is formed near a front top wall of the sliding sleeve 106. The shutter 103 is received in the sliding sleeve 106 through the opening 1061. In an exemplary embodiment of the present invention, the shutter 103 is pivotally connected to the sliding sleeve 106 via a pivotal shaft 1031 across the opening 1061.

As shown in Fig. l, Fig.5 and Fig.7, a front end of the elastic mechanism 102 is pressed against the upper end of the shutter 103, and a rear end of the elastic mechanism 102 is pressed against the housing 101. In the illustrative embodiments, the elastic mechanism 102 comprises a straight spring 1021 and a sheath 1022 sleeved on the straight spring 1021. Furthermore, a positioning tube 1011 is formed on the housing 101. The rear end of the elastic mechanism 102 is received in the positioning tube 1011 and the front end of the elastic mechanism 102 is pressed against the upper end of the shutter 103. The pivotal shaft 1031 is located between the front end of the elastic mechanism 102 and an upper wall of the optical fiber alignment device 104.

As shown in Fig. l and Fig.7, when the fiber optic connector 100 is not inserted into the adapter 200, the elastic mechanism 102 is pressed against the upper end of the shutter 103 over the pivotal shaft 1031 to hold the shutter 103 to a closed position where the alignment hole is closed by the shutter 103 and the sliding mechanism 106 to an initial position.

Please refer to Fig.7, in order to completely cover the alignment hole, the shutter 103 has a concave lower portion for fully covering the protruded front end of the ferrule 1041.

As shown in Fig. l and Fig.5, a tongue 1063 is formed on a front bottom wall of the sliding sleeve 106 and is protruded outside toward the adapter 200. The tongue 1063 is shaped to be fitted into a positioning slot 203 (please see Fig.2B) formed in the adapter 200.

In an exemplary embodiment of Fig. l and Fig.5, a positioning ring 1062 is formed on the sliding sleeve 106 to stably position the front end of the elastic mechanism 102. The front end of the elastic mechanism 102 passes through the positioning ring 1062 in the front-rear direction and is positioned in place by the positioning ring 1062. In this way, the sheath 1022 of the elastic mechanism 102 cannot displace in a direction transverse to the front-rear direction during turning the shutter 103 between the closed position and an opened position where the alignment hole is opened by the shutter 103. Hereafter, it will describe an operation of inserting the fiber optic connector 100 into the adapter 200 in detail with reference to the attached drawings.

Fig.2A is an illustrative perspective view of the fiber optic connector 100 and the corresponding adapter 200 according to the exemplary embodiment of the present invention, in which the tongue 1063 of the fiber optic connector 100 is just inserted into a positioning slot 203 of the adapter 200 and the shutter 103 of the fiber optic connector 100 is in the closed position; Fig.2B shows the fiber optic connector 100 and the adapter 200 of Fig.2A, in which a portion of the housing 201 of the adapter 200 is cut off to partly expose its inner structure and to show the tongue 1063 of the fiber optic connector 100 inserted into the positioning slot 203 of the adapter 200.

As shown in Fig.2A and Fig.2B, in order to correctly insert the fiber optic connector 100 into the adapter 200, a misinsertion-proof mechanism is provided. In the illustrative embodiments, the misinsertion-proof mechanism comprises the tongue 1063 formed on the bottom wall of the sliding sleeve 106 and protruded outside toward the adapter 200, and the positioning slot 203 formed in the housing 201 of the adapter 200. Before inserting the fiber optic connector 100 into the adapter 200, the tongue 1063 of the sliding sleeve 106 must be firstly aligned with the positioning slot 203 of the adapter 200 to ensure that the fiber optic connector 100 can be correctly inserted into the adapter 200. After the tongue 1063 of the sliding sleeve 106 is aligned with and inserted into the positioning slot 203 of the adapter 200, an operator may continuously push the housing 101 of the fiber optic connector 100 toward the adapter 200 to insert the fiber optic connector 100.

Fig.3 A is an illustrative perspective view of the fiber optic connector 100 and the corresponding adapter 200 according to the exemplary embodiment of the present invention, in which the shutter 103 of the fiber optic connector 100 is turned to the opened position by the optical fiber alignment device 104 and the optical fiber alignment device 104 is partly inserted into the adapter 200; Fig.3B shows the fiber optic connector 100 and the adapter 200 of Fig.3A, - lo in which a portion of the housing 201 of the adapter 200 is cut off to partly expose its inner structure.

As shown in Fig.3 A and Fig.3B, after the tongue 1063 of the sliding sleeve 106 is aligned with and inserted into the positioning slot 203 of the adapter 200, the sliding mechanism 106 is blocked by the housing 201 of the adapter 200 and cannot be moved further toward the adapter 200. At this time, when the operator continuously pushes the housing 101 of the fiber optic connector 100 toward the adapter 200, the housings 101 and the optical fiber alignment device 104 of the fiber optic connector 100 both are slid toward the adapter 200 relative to the sliding mechanism 106, as shown in Fig.7. When the housings 101 and the optical fiber alignment device 104 of the fiber optic connector 100 move forward, the shutter 103 is driven by the front end of the upper wall of the optical fiber alignment device 104 underneath the pivotal shaft 1031 against an elastic force of the elastic mechanism 102 and smoothly turned from the closed position shown in Figs.2A-2B to the opened position shown in Figs.3A-3B.

As shown in Figs.2A-2B and 3A-3B, when the shutter 103 is turned from the closed position to the opened position, the shutter 103 is switched from a substantively vertical posture shown in Figs.2A-2B to a substantively horizontal posture shown in Figs.3A-3B. As shown in Figs.3A-3B, when the shutter 103 is in the opened position, the shutter 103 substantively shields the whole opening 1061 formed near the front top wall of the sliding sleeve 106.

While the shutter 103 is opened, the housing 101 and the optical fiber alignment device 104 of the fiber optic connector 100 further move toward the adapter 200 and enter into the housing 201 of the adapter 200. As shown in Fig.3B, the protruded front end of the ferrule 1041 is inserted into the housing 201 of the adapter 200.

Fig.4A is an illustrative perspective view of the fiber optic connector 100 and the corresponding adapter 200 according to the exemplary embodiment of the present invention, in which the optical fiber alignment device 104 is fully inserted into the adapter 200; Fig.4B shows the fiber optic connector 100 and the adapter 200 of Fig.4A, in which a portion of the housing 201 of the adapter 200 is cut off to partly expose its inner structure.

After the protruded front end of the ferrule 1041 is inserted into the housing 201 of the adapter 200, the housing 101 of the fiber optic connector 100 is further pushed forward, in this way, as shown in Figs.4A-4B, the front end of the housing 101 of the fiber optic connector 100 is inserted into the housing 201 of the adapter 200 until the optical fiber alignment device 104 of the fiber optic connector 100 is aligned with and abutted against the other optical fiber alignment device of the adapter 200. After the fiber optic connector 100 is fully inserted into the adapter 200, the housing 101 of the fiber optic connector 100 is engaged with the housing 201 of the adapter 200 by a snapping structure 1012 (please see Fig.5). Although it is not shown, a release mechanism may be formed on the housing 201 of the adapter 200 for disengage the fiber optic connector 100 from the adapter 200. Fig.6 is an illustrative exploded view of the fiber optic connector 100, when seeing from the its bottom, according to the exemplary embodiment of the present invention.

In the exemplary embodiment shown in Fig.6, an elongated sliding rail 1013 is formed on and protruded from a bottom wall of the housing 101. The sliding rail 1013 extends in the front-rear direction of housing 101. Furthermore, a guiding groove (not shown) is formed in the housing 201 of the adapter 200. During inserting the fiber optic connector 100 into the adapter 200, the sliding rail 1013 is fitted in the guiding groove to guide the fiber optic connector 100 to be correctly and smoothly inserted into the adapter 200.

In the present invention, after the fiber optic connector 100 is pulled out of the adapter 200, the shutter 103 can be automatically returned to the closed position shown in Fig.l under being pushed at the upper end of the shutter 103 over the pivotal shaft 103 lby the elastic mechanism 102, and the sliding mechanism 106 can automatically returned to the initial position shown in Fig. l under the push of the elastic mechanism 102.

As shown in Fig. l and Fig.7, the fiber optic connector 100 further comprises a strain relief boot 105 connected to a rear end of the optical fiber alignment device 104 opposite to the shutter 103.

As shown in Fig.5 and Fig.7, at the upper end of the shutter 103 pressed by the elastic mechanism 102 is formed a circular transition corner for achieving a smooth turning of the shutter 103 between the opened position and the closed position.

Referring to Figs.1-7, the shutter 103 has a certain thickness, and the upper end of the shutter 103 pressed by the elastic mechanism 102 may be thicker than the lower end thereof. Furthermore, the upper end of the shutter 103 pressed by the elastic mechanism 102 may have a width that is equal to or slightly larger than the diameter of the sheath 1022. In another exemplary embodiment of the present invention, the upper end of the shutter 103 pressed by the elastic mechanism 102 may have a width less than the lower end thereof. But, the present invention is not limited to this, the shutter 103 may be formed in other different configurations so long as it can cover the alignment hole of the fiber.

Although several exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
