Description

Fiber Optic Adapter

[0001] The present invention relates to an optical fiber adapter having a main part of an integrated structure and a cover part fixed in a hook shape on the upper surface of the main part, which is used to connect connectors on both sides.

[0002] Typically, optical fiber adapters are installed in various types of optical distribution boxes (FDFs) and optical fiber connectors are plugged into the optical fiber adapters for use.

[0003] These optical fiber adapters have been conventionally used in a form in which two bodies are made and joined together to form an integral body.

[0004] For the aforementioned fiber optic adapter, two opposing bodies of identical shape were welded together using ultrasonic welding to form a single body. However, the welded portion was prone to breaking under external force. Therefore, there is a need to develop an adapter that addresses this issue while also improving the assembly structure of the internal components.

[0034] Before explaining various embodiments of the present invention in detail, it is to be understood that the details of the construction and arrangement of the components set forth in the following detailed description or illustrated in the drawings are not intended to limit the scope of the invention. The present invention may be embodied and practiced in other embodiments and carried out in various ways. It is also to be understood that expressions and terminology used herein with respect to device or element orientation (e.g., “front,” “back,” “up,” “down,” “top,” “bottom,” “left,” “right,” “lateral”), and the like, are used merely to simplify the description of the invention and do not indicate or imply that the associated device or element must have a particular orientation. Furthermore, terms such as “first,” “second,” and the like are used herein and in the appended claims for descriptive purposes and are not intended to indicate or imply relative importance or intent.

[0035] The present invention has the following features to achieve the above purpose.

[0037] Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0038]

[0039]

[0040] Hereinafter, an optical fiber adapter according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

[0041] The optical fiber adapter according to the present invention is used for the purpose of connecting two connectors by combining them on both sides, and includes a main part (10), a sleeve holder (20), and a cover part (30).

[0042]

[0043] The above main part (10) is a hollow rectangular tube shape with an empty interior, and has insertion holes formed on both left and right ends for inserting the connector, and has a mounting hole (11) formed in a rectangular shape at the top, so that the cover part (30) described later is mounted accordingly.

[0044] Since this main part (10) is manufactured as a single integral body rather than as a conventional method of manufacturing two bodies by ultrasonic welding, problems such as the welding part breaking or bending due to external force do not occur as in the conventional method.

[0045]

[0046] The above sleeve holder (20) is a part that is inserted and fixed by being assembled in correspondence with each other within the aforementioned main part (10).

[0047] In the case of this sleeve holder (20), it has a structure in which two first and second sleeve holders (21, 22) having the same shape are assembled facing each other with a tubular sleeve (28) in between.

[0048] These first and second sleeve holders (21, 22) are composed of a sleeve fixing tube part (26) into which a sleeve (28) is fitted, and a fastening part (27) that is formed to extend in a hook shape in the longitudinal direction so that two tube parts (26) are positioned on both sides.

[0049] The first and second sleeve holders (21, 22) are formed with a joining projection (24) and a joining groove (25) on both sides, respectively, and have a structure in which the joining projection (24) of the first sleeve holder (21) corresponds to the joining groove (25) of the second sleeve holder (22), thereby having a structure in which the connecting plates (23) of the first and second sleeve holders (21, 22) are assembled while making surface contact with each other.

[0050] Of course, in order to fix the sleeve holder (20) assembled in this way within the main part (10), an insertion line (13) is formed in the inner center of the main part (10) and the center of the bottom surface of the cover part (30) so that the edges of the connecting plates (23) of the assembled first and second sleeve holders (21, 22) are fitted in correspondence, thereby allowing the sleeve holder (20) to be positionally fixed within the main part (10).

[0051]

[0052] The above cover part (30) is a square plate part that is mounted and fixed in the form of a cover in response to the aforementioned square mounting hole (11).

[0053] For this purpose, the cover part (30) is formed with a plurality of hook parts (31) having a hook shape (e.g., a total of 4) on the bottom edge, and a hook groove (12) is formed on the edge of the mounting hole (11) of the main part (10) to which the hook parts (31) correspond and are hooked, so that the upper part of the main part (10) is sealed.

[0054] In addition, the cover part (30) may be formed with a plurality of guide pieces (32) that protrude vertically downward on the bottom edge where the hook part (31) is formed (e.g., a total of 4 pieces), so that the cover part (30) can be mounted in the mounting hole (11) while being guided at an accurate position by the guide pieces (32).

[0055] In addition, the cover part (30) is formed with protrusions (33) protruding toward the bottom on both sides of the stop, and a protrusion groove (14) is formed on the upper surface of the main part (10) to which the protrusions (33) are fitted in correspondence, so that the cover part (30) can be more securely fixed to the main part (10).

[0056]

[0057]

[0058]

[0059] As described above, although the present invention has been described by limited embodiments and drawings, the present invention is not limited thereto, and various modifications and changes are possible within the scope of the technical idea of ​​the present invention and the equivalent scope of the patent claims to be described below by a person having ordinary skill in the art to which the present invention pertains.
