Description

adapter

The present invention relates to an adapter, and more particularly to an adapter that can correspond to a multi-fiber push-pull fiber optic connector.

Multi-Fiber Push On (MPO) fiber optic connector is a connector suitable for high-density fiber-optic network configuration. Multi-fiber push-pull fiber optic connector has the characteristics of high-density fiber in a limited space. Therefore, it plays an important role in the communication industry with increasing traffic.

Referring to FIG. 1 and FIG. 2, the existing multi-fiber push-pull male connector optical fiber connector 1 is generally used corresponding to a matching adapter 2, and two optical fiber connectors 1 and 3 for the male and female connectors respectively can be respectively provided at the two ends of the adapter 2. Plug in. A common male connector fiber optic connector 1 includes a connector body 11 and a ferrule tip 12 disposed at the end of the connector body 11. The ferrule end 12 includes an end main body 121, a ferrule 122 through which the end main body 121 is spaced apart from each other, and a holder 123 disposed on the end main body 121 and fixing the ferrules 122. The adapter 2 includes an outer casing 21 defining an insertion hole 210, and two outer peripheral surfaces of the outer casing 21 spaced apart from each other so as to be located in the insertion hole 210.

When the male connector fiber connector 1 is to be mounted on the adapter 2, the ferrule end 12 is inserted into the latching block 22 and inserted into the insertion hole 210 at the ferrule end 12 After the latching blocks 22 are completely inserted into the insertion holes 210, the latching blocks 22 are reset and blocked against the holder 123 of the ferrule end 12, thereby reaching the limit of the ferrule end 12 Efficacy, it should be particularly noted that although the latching blocks 22 only block against the holder 123, the front end body 121 is usually provided with a female connector fiber connector 3 in front of it, so that no additional limit is required. However, when the male connector optical connector 1 is to be detached from the adapter 2, since the latching blocks 22 are hooked to the retainer 123 in a barb shape, the direct detachment is received by the latching block 22. The blockage causes the user to apply excessive force to cause the optical fiber connector 1 and the adapter 2 to be easily damaged. In addition, the card block 22 is hidden in the insertion hole 210, so the card is to be used. When the block 22 is opened, it is often necessary to use another tool to operate, and the disassembly is very inconvenient, so that the conventional adapter 2 still has room for improvement in structural design.

Accordingly, it is an object of the present invention to provide an adapter that removes the ferrule tip without the need for tools.

Thus, the new adapter is suitable for use with a ferrule tip. The adapter includes a casing, two clamping members disposed on the casing at a distance from each other in a first direction and for clamping the ferrule ends, and a set of ferrules disposed on the ferrule ends and detachably Auxiliary parts that are combined with the card members.

The auxiliary member is operatively movable relative to the card members in a front-rear direction between a carding position and a disengagement position. When the auxiliary member is in the carding position, the auxiliary member is engaged in the card. And the card member stops the ferrule end from being disengaged from the card member, and when the auxiliary member is in the disengaged position, the card member is distracted in the first direction by the auxiliary member Away away from each other, the ferrule ends are disengaged from the cards in the fore and aft direction.

The utility model has the advantages that the user only needs to insert and remove the auxiliary member by hand, and the card can be driven away from each other, and the ferrule end is detachable, and the ferrule end is detached. The removal from the card is simple and requires no additional tools.

Referring to Figures 3, 4, and 5, an embodiment of the present type of adapter 4 is adapted to cooperate with a ferrule end 5 extending in a front-rear direction A and defined for the MT Ferrule specification to define a vertical direction. a first direction B of A, and a second direction C perpendicular to the front-rear direction A and the first direction B. In the embodiment, the front-rear direction A is from the ferrule end 5 toward the outer casing 6. The direction is the front and the reverse direction is the rear. The first direction B corresponds to the left-right direction, and the second direction C corresponds to the vertical direction. The adapter 4 includes a casing 6 and two engaging members 7 spaced apart from each other in the first direction B and extending rearwardly from the casing 6 in the front-rear direction A, and a set is disposed on the ferrule end 5 and An auxiliary member 8 that is separately coupled to the fasteners 7. The outer casing 6 includes a front opening 61 and a rear opening 62 spaced apart from each other in the front-rear direction A, and two extending walls 63 spaced apart along the second direction C and located between the clamping members 7. And two limiting posts 64 respectively protruding away from each other in the second direction C by the extending walls 63. The front opening 61 is for the end of an MPO fiber connector (not shown), the rear opening 62 is for the ferrule end 5, and the ferrule end 5 belongs to another MPO fiber connector. A portion of the (not shown) portion of the two MPO fiber optic connectors will be in contact with each other and optically coupled within the housing 6.

Each of the clamping members 7 is flexible and respectively located on the left and right sides of the rear opening 62, and includes an extending portion 71 extending rearward from the outer casing 6, and a direction along the first direction B from the extending portion 71 toward the other A hook portion 72 projecting from the card member 7 and a bump portion 73 projecting upwardly and downwardly from the extending portion 71 in the second direction C. The auxiliary member 8 includes a sleeve portion 81 defining an inner space 810 for receiving the ferrule end 5, and four guides disposed in the inner space 810 and protruding from the inner wall surface of the sleeve portion 81. The block portion 82 (the two guide block portions 82 located above in FIG. 3 are shielded so that only the two guide block portions 82 located below) are displayed, and a cover portion 81 projects downwardly from the inner space 810 The card portion 83 in the middle. The sleeve portion 81 defines two sliding slots 811 extending in the front-rear direction A and respectively extending from the limiting posts 64. When the auxiliary member 8 is coupled to the engaging members 7, the engaging members 7 are located in the inner space 810, and the limiting posts 64 are slidably extendable along the sliding slots 811, respectively. In the chutes 811. The guide block portions 82 are spaced apart from each other along the first direction B and the second direction C so as to correspond to the bump portions 73 so as to be pressed against the bump portions 73. Each of the guide blocks 82 has a positioning surface 821 parallel to the front-rear direction A, a first oblique guiding surface 822 connected to the front end of the positioning surface 821 and extending forwardly and gradually outwardly inclined, and a connection The first oblique guide surface 822 has a front end and a second oblique guide surface 823 that extends forward and gradually collapses inwardly and is inclined inward.

The auxiliary member 8 is movable relative to the card member 7 between a carding position and a disengagement position. When the auxiliary member is in the carding position as shown in FIG. 5, the bump portions 73 are abutted. The positioning surface 821 of the guiding block portion 82 is not deformed, so that the distance between the hook portions 72 is smaller than the width of the ferrule end 5 in the first direction B, and further The ferrule tip 5 can be limited to the front of the hook portion 72.

Referring to FIG. 4, FIG. 5, and FIG. 6, when the user wants to remove the ferrule end 5, it is only necessary to hold the auxiliary member 8 and pull it back relative to the outer casing 6 and the clamping members 7, Thus, the auxiliary member 8 can be moved from the carding position shown in FIG. 5 to the disengaged position as shown in FIG. 6. It should be particularly noted that the following description is based on the card members 7 relative to The manner in which the auxiliary member 8 is moved is described, but the outer casing 6 and the intermediate members 7 are not actually moved. During the movement of the auxiliary member 8 from the clamping position to the disengaged position, each of the lug portions 73 first slides forward along the corresponding positioning surface 821 and then slides along the first oblique guiding surface 822. During the sliding along the first oblique guiding surface 822, the convex portion 73 is gradually outwardly displaced along the first direction B, so that the corresponding extending portion 71 is driven to be slightly bent outward, thereby making the same The hook portions 72 are away from each other in the first direction B. When the auxiliary member 8 is in the disengaged position, the distance of the hook portions 72 in the first direction B is greater than the first end of the ferrule 5 at the first The width in the direction B is such that the ferrule end 5 is detachable. At this time, the ferrule end 5 can be continuously removed and pulled out from the card member 7, which requires special attention. That is, since the limit posts 64 are still located in the chutes 811, the auxiliary member 8 is still attached to the outer casing 6. In the foregoing process, the auxiliary member 8 pushes the ferrule end 5 backward through the latch portion 83 to drive the ferrule end 5 to move backward.

On the other hand, when the detached ferrule end 5 is to be placed on the card member 7, the ferrule end 5 is first inserted into the auxiliary member 8, and then the card members are aligned. After the gap of 7 is inserted into the ferrule end 5, the ferrule end 5 pushes the latching portion 83 to drive the auxiliary member 8 to move forward, and the limiting posts 64 are respectively along the chutes The 811 is relatively slipped (actually moving the auxiliary member 8, and thus is "relative" slip), and the projections 73 of the clips 7 are first slid along the second oblique guides 823, respectively. When moving to the intersection of the second oblique guiding surface 823 and the first inclined guiding surface 822, the hook portions 72 are away from each other in the first direction B (when the auxiliary member 8 is located at the separation) Position), and the distance is available for the ferrule end 5 to be inserted, and the ferrule end 5 is pushed forward before the ferrule end 5 can be placed in front of the hook portions 72, and the auxiliary The piece 8 is moved from the disengaged position to the engaged position, thereby completing the fixing of the ferrule end 5.

It should be noted that the number of the bump portions 73 of the clips 7 and the guide portions 82 of the auxiliary members 8 may be only two, and is not limited thereto.

In summary, through the design of the guiding portions 82, the protruding portions 73 can be slid along the hook portions 72 to open outwardly, so that the ferrule ends 5 are detachable. In this way, the effect of quickly disassembling the ferrule end 5 without tools is achieved, so that the purpose of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
