Referring to Figures 5 and 6, the optical fiber adapter 500 having the light shielding member of the first embodiment of the present invention comprises a light-shielding member 570 integrally formed of metal and elastic, and a body 510 which is formed by plastic molding and is substantially rectangular. . The body 510 has a top side wall 511, a bottom side wall 512, a right side wall 513 and a left side wall 514, which together define an axial chamber 515. Further, in the axial chamber 515., an inner casing 56 is provided, such as a clamping assembly, which includes a substantially rectangular flange 562 having a pair of retaining clips 564 on the surface of the flange 562. And a circular hollow cylinder 568 positioned between the two retaining clips 564. On the left and right side walls 514, 513 of the body 51'', an opening 518 is formed. At the interface between the left and right side walls 514, 513 and the bottom side wall 512, a recess 519 is formed, respectively, which extends from the edge of the bottom side wall 512 toward the axial housing 515. The elastic light-shielding member 570 is integrally formed of metal, and is packaged in the package of the invention. The east cover 8 201241495 includes a light-shielding portion 572, a ® a & and a fixing portion such as a connection and a light-shielding claw system. Generally, it is a ^ tr junction 574. The connecting portion 574 has an arc-shaped I surface and/or a notch 576. The light-shielding part 572 can be formed by 1 or by two flat plates. When the light-shielding part is reversed to the thrust, it will be close to the fixed part 582. After the force disappears, the light-shielding part 572 will return to the fixed part due to its own elastic force. The 582 includes a flat portion (8) in the form of a flat plate and a pair of extending portions 586 extending from opposite side parallel plates of the horizontal portion 584.

Inside the recess 519. Since the distance between the front ends of the two hook portions 594 is greater than the distance between the left and right side walls 514, 513, the hook portion 594 is compressed during the installation of the light blocking member 570, and the front end thereof is touched. - TW-Invention Manual - Dongpu ^9 201241495 - Move to the left and right side walls 514, 513 and toward the opening 518. When the card feeding portion 594 is moved to the opening 518, since the left field, the right wall, and the walls 514, 513 are no longer pressed, the hook portion 594 will return to its original state due to its own elasticity and elasticity, and its front end will extend. When the opening 51 is pushed into position, the horizontal portion 584 will be attached to the bottom side wall 512, and the extension 586 will be moved into the recess 519, and the protrusion 588 thereon will abut On the two walls of the recess HQ. If a pulling force is applied to the light blocking member 57 at this time, the knowledge of the hook 594 will abut against the opening $1 $ to prevent the light blocking member from being pulled out of the body 510. Therefore, according to the fiber optic adapter 500 of the present invention, when the light blocking member 57 is in the clamp position, the 'light shielding portion 572 will be positioned in front of the opening of the hollow cylinder 568', thereby blocking the light beam emitted therefrom, thereby avoiding the light beam. Injure the eyes. Referring to Figures 8 and 9, when the fiber optic connector 4 is to be docked with the fiber optic adapter 500 of the present invention, the shading device 57 is not required to be removed first, and the connector 400 is directly inserted into the axial chamber of the body 51〇. It can be within 515, at which time the shade portion 572 will be squeezed into the gap between the connector * (9) and the bottom (four) 512 of the housing. When the connector 働 is pulled out of the adapter 500, the light shielding portion 572 returns to the original position due to its own returning elasticity, and has a function of blocking the light beam. In addition, when the optical fiber connector 400 is inserted into the body 51, the light-shielding portion 572 is pressed by the connector 400, causing the root portion to be elastically moved toward the 01560-TW-invention specification-dong. · 10, 201241495 · , \ . Uplifting' thus pulling the nearby horizontal portion 584 so that the edge of the horizontal portion 584 will be lifted up. In order to solve the above problem, the extending portion 586 extending from the horizontal portion 584 is disposed in the concave portion 519 and abuts against the inner wall of the concave portion 519 by the protrusion 588 thereon, thereby preventing the horizontal portion 584 from being pulled by the light blocking portion 572.

When the opening 518 is a through hole, the elongated rod can be used to pass through the opening 518 to shrink the two fishing portions 594. At this time, the light shielding member 570 can be pulled out of the body 510. Referring to Fig. 10, a fiber optic adapter 600 having a light-shielding member according to a second embodiment of the present invention comprises a light-shielding member 670 integrally formed of metal and elastic, and a body 610 formed by plastic molding and having a substantially rectangular shape. The shade 670 is substantially identical to the shade 570, and the same reference numerals are used to designate the same elements. Different from the light blocking member 570, the light blocking member 67 of the present embodiment is not provided with the extending portion 586 and the protrusion 588, but a hook 696 is extended from the connecting portion 574. The hook 696 is generally L-shaped and includes a downwardly extending vertical portion 697 and a horizontal portion 698 extending horizontally from the vertical portion 697 toward the connecting portion 574. The remaining components of the light shielding member 670 are the same as those of the light shielding member 57, and will not be described herein. The body 610 of the present embodiment is substantially identical to the body * Οΐβθ-TW-invention specification, 侑 侑 · · 2012 2012 2012 2012 2012 2012 2012 2012 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Different from the body 510, since the light shielding member 67 of the embodiment is not provided with the extending portion 586, the body 61 of the present embodiment does not need to be at the boundary between the left and right side walls 514, 513 and the bottom side wall 512. A recess 519 is formed. Additionally, a recess 517 is formed in the bottom side wall 512 outside of the axial chamber 515 that extends to the edge of the bottom side wall 512 for receiving the horizontal portion 698 of the hook 696. The remaining tl parts of the body 61 are the same as those of the body 510, and will not be described again. Referring to Fig. 11, there is shown a perspective view in which the light blocking member 67 is mounted on the body 610. The hook portion 5 of the light blocking member 67 of the present embodiment extends into the opening 518 of the body 6H), and the horizontal portion 584 of the light blocking member 67 is similar to the manner in which the light blocking member 57 is mounted on the body. It will also be attached to the bottom side wall 5i2. of the body 61〇. In addition, when the light blocking member 670 is pushed into position, the horizontal portion 698 of the hook 696 abuts against the bottom side wall 512 outside the axial chamber 515, for example, a recess attached to the bottom side wall 512. ? Inside. Therefore, when the optical fiber connector 400 is inserted into the body 61 to cause the light shielding portion 572 of the light shielding member 670 to be pressed down, the hook 696 of the light shielding member 67 is hooked on the bottom side wall 512 outside the axial chamber 515, so that the connection is made. Therefore, the portion 574 cannot be lifted, and the problem that the connecting portion 574 of the light shielding member 67A and the horizontal portion 584 are lifted up are solved. Similarly, according to the optical fiber adapter 6〇〇 of the present invention, when the light-shielding 01560|the invention indicates that the fainting 侑 2012 201241495 (6) arrives at the positioning, the opaque portion 572 thereof will be positioned in front of the opening of the hollow cylinder "can be interrupted by The beam emitted by the beam, thereby preventing the beam from damaging the eye. Although the U sc type fiber optic adapter is exemplified in the present month, it should be understood by those having ordinary knowledge in the technical field of this & month: The fiber optic adapter can be adapted to other types of optical fibers, for example, the type of optical fiber adapter 7 shown in Fig. 12. Since the optical storm fits the adapter 70.0, the light-shielding member 77 and the light-shielding member 570 are included. The structure is similar, and the manner of mounting on the fiber optic adapter 7 is the same, so the fiber adapter 700 will not be described in detail. Although the invention has been disclosed in the foregoing embodiments, it is not intended to limit the invention, any A person skilled in the art having ordinary knowledge can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention is attached to the application. The definition is based on the scope of interest.
