Description

Technology Field

[0001] This embodiment relates to an optical cable connection box that improves the convenience of installation compared to conventional ones. Background Technology

[0002] The content described in this section merely provides background information regarding the present embodiment and does not constitute prior art.

[0003] In general, data transmission methods using optical fibers are widely utilized in the telecommunications field because they are significantly superior to conventional methods that transmit data using electrical signals in terms of transmission speed and the quality of the transmitted signal.

[0004] Since optical fibers are manufactured by drawing transparent dielectric materials, such as quartz glass or plastic, into long, thin strands, they have the disadvantage of being relatively weak in strength due to the inherent properties of the material. For this reason, the outer surface of the optical fiber is coated with a cushioning cover or similar material to be manufactured into a cable form.

[0005] Meanwhile, the optical cable junction box performs the function of connecting and distributing between the external optical line and the subscriber transmission device; when a portion of the incoming optical fiber is connected to the optical fiber of the optical adapter and distributed to a nearby subscriber transmission device, the remaining optical fibers are drawn out again in the form of an optical cable and distributed to a subscriber transmission device at a long distance.

[0006] However, in the case of conventional optical cable junction boxes, the cable clamp and tension wire holder that fix the optical cable and the tension wire of the optical cable are assembled separately inside the box, so there was a cumbersome inconvenience in the assembly process and replacement of these parts. In addition, conventionally, optical fibers were spliced ​​by performing fusion splicing between two optical cables to install the optical cable junction box, so separate equipment for fusion splicing was required. Consequently, during the installation process of conventional optical cable junction boxes, there was an inconvenience in having to provide and operate the corresponding equipment for splicing. The problem to be solved

[0007] One embodiment of the present invention has the objective of providing an optical cable connection housing that eliminates the splicing process between optical fibers or optical cables and improves the convenience of installation compared to conventional methods. means of solving the problem

[0008] According to one aspect of the present embodiment, a connection housing for connecting optical fibers within two optical cables and maintaining a connection state comprises: a main body of the housing that receives one or more pairs of optical cables to be connected and connects the optical fibers within the optical cables internally; a cover that protects the main body of the housing from an external environment by including a space within which the main body of the housing can be received and arranged; and a fixing means for fixing the cover and the main body of the housing. The main body of the housing comprises one or more optical fiber coupling trays that allow optical fibers within the optical cables to be connected to each other to be connected, one or more pairs of optical cables to be connected to each other, an optical cable connection body that receives one or more optical cables to be connected to each other and allows the received optical fibers within the optical cables to be introduced into the optical fiber coupling tray, and a tray connection body that is coupled to the optical cable connection body and one or more optical fiber coupling trays respectively to fix the optical fiber coupling tray. The optical fiber coupling tray fixes one optical fiber to be connected to a body and another optical fiber, and comprises a plurality of field-type LC connectors that contact other connectors coupled at a position facing itself or a corresponding position, and a radius predetermined from the central part of the body or from thereto. A connection enclosure is provided that includes a plurality of adapters located inside, which allow each field-type LC connector to be coupled, and which rotate and have one side exposed toward the top.

[0009] According to one aspect of the present embodiment, the optical fiber coupling tray further comprises an adapter fixing portion for seating each adapter.

[0010] According to one aspect of the present embodiment, the adapter fixing part is provided in a number equal to the number of adapters.

[0011] According to one aspect of the present embodiment, the adapter fixing part is characterized by receiving an external force to rotate or fix the adapter.

[0012] According to one aspect of the present embodiment, the adapter fixing portion is characterized by having a groove having a width equal to the width of the adapter to seat the adapter.

[0013] According to one aspect of the present embodiment, the adapter fixing part is coupled to the body to rotate or fix the adapter.

[0014] According to one aspect of the present embodiment, the adapter fixing part is characterized by rotating the adapter when coupled to the body only at one end, and fixing the adapter when coupled to the body at both ends. Effects of the invention

[0024] FIG. 1 is a drawing illustrating the configuration of a connection box according to one embodiment of the present invention.

[0025] Referring to FIG. 1, a connection housing (100) according to one embodiment of the present invention includes a cover (110), a fixing means (120), and a housing main body (130).

[0026] The connection box (100) conveniently connects an optical cable connected to one piece of equipment and an optical cable connected to another piece of equipment internally, and maintains the state. At this time, unlike conventional ones, the connection box (100) simplifies the connection process and structure of the two optical cables to be connected, thereby significantly reducing the cost and time of the installation process.

[0027] The cover (110) includes a space in which the main body of the enclosure (130) can be inserted and placed, thereby protecting the main body of the enclosure (130) from the external environment.

[0028] The cover (110) includes a groove (115) into which a valve (not shown) can be installed. By connecting the valve (not shown) to the groove (115), the inside of the cover (110) can be further sealed by expelling air from inside the cover (110) to the outside. Accordingly, the cover (110) can more thoroughly prevent the main body (130) of the enclosure from being exposed to the external environment.

[0029] The fixing means (120) fixes the cover (110) and the main body of the housing (130) and seals the main body of the housing (130) inside the cover (110). The fixing means (120) includes a groove (not shown) into which one end portion of the cover (110) (the vertically downward end in FIG. 1) and a part of the main body of the housing (130) can be inserted. When each of the aforementioned parts is inserted into the groove (not shown), the fixing means (120) seals the inside of the cover (110) while fixing the cover (110) and the main body of the housing (130) by applying force to each part in a direction that brings them closer to each other.

[0030] The main body of the enclosure (130) receives one or more pairs of optical cables to be connected and connects the optical fibers within the optical cables internally. The main body of the enclosure (130) can easily connect the optical fibers using field-type LC connectors and adapters, thereby resolving the problems of conventional connection enclosures.

[0031] FIG. 2 is a drawing illustrating the configuration of a main body of a housing according to one embodiment of the present invention.

[0032] Referring to FIG. 2, a main body (130) of a housing according to one embodiment of the present invention includes an optical cable connection body (210), a tray connection body (220), and one or more optical fiber coupling trays (230).

[0033] The optical cable connection body (210) receives one or more pairs of optical cables to be combined with each other, and allows the optical fibers within the received optical cables to be fed into the optical fiber coupling tray (230). The specific structure of the optical cable connection body (210) is illustrated in FIGS. 3 to 5.

[0034] FIG. 3 is a drawing illustrating the configuration of an optical cable connection body according to one embodiment of the present invention, FIG. 4 is a drawing illustrating the configuration of a cable seating portion according to one embodiment of the present invention, and FIG. 5 is a drawing illustrating the configuration of a cable fixing portion according to one embodiment of the present invention.

[0035] Referring to FIGS. 3 to 5, an optical cable connection body (210) according to one embodiment of the present invention includes an optical cable inlet part (310), a cable seating part (320), a cable fixing part (325), a fixing means coupling part (330), and a tray connection body coupling part (335).

[0036] The optical cable entry section (310) is formed at the farthest end from the optical fiber coupling tray (230) within the optical cable connection body (210), allowing the optical cable to be fed into its interior. At least two optical cable entry sections (310) are formed at the aforementioned location, protruding (by a predetermined length) from the fixing means coupling section (330). Since each optical cable to be coupled must be fed in, at least two optical cable entry sections (310) must be formed. The optical cable entry section (310) has an inner diameter larger than the diameter of the optical cable, thereby allowing the optical cable to be fed into its interior. As the optical cable is fed into the interior of the optical cable entry section (310), the movement or detachment of the fed optical cable can be minimized.

[0037] The cable seating portion (320) is formed at the end (farthest from the position where the optical cable is inserted) of the optical cable inlet portion (310) of the optical cable connection body (210) to seat the optical cable inserted into the optical cable inlet portion (310). The cable seating portion (320) seats the optical cable to minimize detachment or movement.

[0038] As illustrated in FIG. 4, the cable seating portion (320) includes a groove (420) larger than the diameter of the optical cable within the body (410), so that the optical cable inserted into the groove (420) can be seated. At this time, as a protrusion (430) is formed on the surface of the groove (420), the movement or rotation of the optical cable in one direction can be minimized.

[0039] Referring again to FIG. 3, the cable fixing part (325) fixes the optical cable that is introduced together with the cable seating part (320). The cable fixing part (325) is positioned facing the cable seating part (320) to fix the optical cable seated on the cable seating part (320) as much as possible.

[0040] As illustrated in FIG. 5, the cable fixing part (325) includes a first body (510) and a second body (520), and each body (510, 520) includes a groove (514, 524) that allows an optical cable to be positioned. As the groove (514, 524) is formed within the body (510, 520) of the cable fixing part (325), when the cable seating part (320) and the cable fixing part (325) are combined, a space is formed through which the optical cable can pass and is seated / fixed inside. In addition, as with the cable seating part (320), protrusions (518, 528) are formed on the surface of each groove (514, 524), thereby bringing about the aforementioned effect.

[0041] At this time, the cable fixing part (325) may include one or more bodies containing each component (groove, protrusion) inside. The diameter of the optical cable may vary depending on the case of use. Consequently, if the cable fixing part (325) includes only a groove of a predetermined standard in a situation where it is unknown what diameter the optical cable will have when it is inserted into the optical cable connection body (210), the inserted optical cable may not be fully fixed by the cable seating part (320) and the fixing part (325). To prevent this, the cable fixing part (325) may include a plurality of bodies (510, 520) as shown in FIG. 5. Each body (510, 520) has a detachable structure, thereby allowing the size (inner diameter or diameter) of the groove formed within the cable fixing part (325) to vary.

[0042] Referring again to FIG. 3, the fixing means coupling part (330) provides a space for the optical cable inlet part (310), the cable seating part (320), and the cable fixing part (325) to be formed, and has a structure to be coupled to the fixing means (120). The fixing means coupling part (330) has a structure larger than a predetermined area so that the optical cable inlet part (310) can be formed on one side far from the optical fiber coupling tray, and the cable seating part (320) and the cable fixing part (325) can be formed at a position corresponding to the optical cable inlet part (310) on the opposite side.

[0043] In addition, the fixing means coupling portion (330) has a thickness such that the entire coupling portion can be inserted into the fixing means (120), or includes a portion having a thickness such that it can be inserted into the fixing means (120), thereby allowing the main body of the housing (130) to be fixed to the fixing means (120).

[0044] The tray connection body coupling portion (335) provides a space that can be coupled with the tray connection body (220). The tray connection body coupling portion (335) can be coupled with the tray connection body (220) by means of coupling means such as bolts / nuts, and provides a space in which the tray connection body (220) is positioned and the coupling means can be coupled for coupling.

[0045] Referring again to FIG. 2, the tray connection body (220) is connected to the tray connection body coupling part (335) and one or more optical fiber coupling trays (230), respectively, to fix the optical fiber coupling trays (230).

[0046] The tray connection body (220) includes a coupling part (224) that can be coupled with an optical fiber coupling tray (230) inside, so that the optical fiber coupling tray (230) can be coupled to and fixed to it. To enable a plurality of optical fiber coupling trays (230) to be coupled, the tray connection body (220) includes a plurality of coupling parts (224), and to prevent problems from occurring even if a plurality of optical fiber coupling trays (230) are all coupled at once, each coupling part (224) is implemented with a distance of at least the height of the optical fiber coupling tray (230) (length in the vertical direction in FIG. 2) in the height direction of the optical fiber coupling tray (230). In particular, each coupling part (224) is implemented with a distance of the aforementioned distance, and at the same time, is also implemented with a certain distance in the length direction of the optical fiber coupling tray (230) within the tray connection body (220). That is, each coupling part (224) is implemented with a height gap, and together with this, as it moves vertically downward, it is positioned to gradually move further away from or closer to the optical cable connection body (210). As a result of this implementation, it is convenient to distinguish and connect each optical fiber coupling tray (230) to each coupling part (224), and it is also convenient to distinguish, identify, and manage the already connected optical fiber coupling trays (230).

[0047] A tray support (228) is implemented at the bottom of the tray connection body (220). The tray support (228) is formed at the bottom of the coupling part (224) formed at the bottom in the vertical direction within the tray connection body (220) and supports the optical fiber coupling tray (230) coupled to the bottom coupling part (224). The tray support (228) is implemented with the same shape as the optical fiber coupling tray (230) or has at least a larger surface area than the optical fiber coupling tray (230), thereby preventing the optical fiber coupling tray (230) coupled to the bottom coupling part (224) from detaching.

[0048] The optical fiber coupling tray (230) is coupled to the tray connection body (220) so that optical fibers (in the optical cable) to be connected to each other can be connected. The optical fiber coupling tray (230) has a structure in which a predetermined number of optical fiber pairs can be introduced and connected inside. The specific structure of the optical fiber coupling tray (230) is illustrated in FIG. 6 or 7.

[0049] FIG. 6 is a diagram illustrating the configuration of an optical fiber coupling tray before separation according to one embodiment of the present invention.

[0050] Referring to FIG. 6, an optical fiber coupling tray (130) according to one embodiment of the present invention includes a body (605), an outflow / inflow section (610, 615), a tray spacing section (620), an optical fiber detachment prevention section (625), an optical fiber winding section (630), an optical fiber stopping section (640), an optical fiber fixing section (650), an adapter (660), an adapter fixing section (670), a field-type LC connector (680), and a body coupling section (690).

[0051] The body (605) provides a space for an optical fiber to be introduced and connected inside, and a space for each component to be formed within the optical fiber coupling tray (130). The end far from the outflow / inflow section (610, 615) of the body (605) is implemented in an elliptical shape or has curvature at each corner, so that the optical fiber introduced into the body (605) can be smoothly wound along the body (605) into the optical fiber winding section (630) or smoothly coupled to one side of the adapter (660).

[0052] The body (605) has a bottom surface that provides space for each configuration to be implemented within the optical fiber coupling tray (130), and wall structures protruding vertically at each end of the bottom surface to prevent optical fibers introduced into the interior from escaping to the exterior.

[0053] In addition, the body (605) is structurally coupled with a part of the adapter fixing part (670) so that the adapter fixing part (670) can rotate. Such structural features of the body (605) will be described later with reference to FIG. 7.

[0054] One or more outflow / inflow sections (610, 615) are implemented at one end of the body (605) to allow optical fibers for connection to be introduced. The outflow / inflow sections (610, 615) are implemented in an open form in a wall structure located at one end of the body (605) to allow optical fibers to be introduced into or out of themselves. Each outflow / inflow section (610, 615) may have at least two outflow / inflow passages, so that optical fibers to be connected to each other can be introduced using different passages.

[0055] The tray spacing maintenance part (620) is a structure protruding from each wall structure of the body (605) and maintains the spacing (in the vertical direction) between the optical fiber coupling trays (130). As described above, the optical fiber coupling trays (230) can each be coupled to a plurality of coupling parts (224) within the tray connection body (220). However, if a plurality of optical fiber coupling trays (230) are coupled to each coupling part (224) without separate configuration, a problem may occur in which the body (605) inside the tray located at the top presses against other components inside the tray located at the bottom. If the body (605) inside the tray located at the top presses against the optical fiber introduced into the tray located at the bottom, there is a risk of adverse effects on the optical fiber. To prevent such problems, the tray spacing member (620) protrudes vertically upward within the wall structure of the body (605) at a position higher than the vertical height of other components within the optical fiber coupling tray (230), thereby allowing the body (605) within the tray located above to be seated and supported on its upper side. By supporting the tray located above (more specifically, the body), the tray spacing member (620) prevents other components from being damaged or broken by the tray located above.

[0056] The optical fiber detachment prevention part (625) is a structure protruding from each wall structure of the body (605) (at a different location from the tray spacing maintenance part (620)) and prevents the optical fiber introduced through the outflow / inflow part (610, 615) from detaching. As the optical fiber detachment prevention part (625) is implemented in a form protruding from the wall structure, the optical fiber introduced into the body (605) is prevented from detaching to the outside of the body (605).

[0057] One or more optical fiber winding sections (630) are each implemented at a position close to the outflow / inflow sections (610, 615) within the body (605) and at a position far from the outflow / inflow sections (610, 615), so that optical fibers introduced for connection can be wound. Optical fibers to be connected into the body (605) are introduced. However, it is almost impossible for the length of the introduced optical fibers to perfectly match the length from the outflow / inflow sections (610, 615) to the field-type LC connector (680) (a concept different from the concept of physical displacement). Accordingly, the optical fiber winding sections (630) are formed at each position to allow the introduced optical fibers to be wound, so that the ends of the introduced optical fibers can be easily connected to the field-type LC connector (680).

[0058] The optical fiber blocking section (640) is implemented between the optical fiber winding section (630) and the optical fiber fixing section (650) at each location within the body (605), thereby preventing the optical fiber wound in the optical fiber winding section (630) from entering the direction of the optical fiber fixing section (650). Even if the optical fiber is wound in the optical fiber winding section (630), it is difficult to wind it tightly in the optical fiber winding section (630), and a considerably long optical fiber may be wound in the optical fiber winding section (630). In this case, even if the optical fiber is wound in the optical fiber winding section (630), it may become excessively stretched in the direction of the optical fiber fixing section (650). This is not a problem if a pair of optical fibers are introduced into the body (605) and connected. However, if multiple pairs of optical fibers are connected, if one optical fiber becomes excessively stretched in the direction of the optical fiber fixing section (650), it may cause a problem of obstructing the path of other optical fibers. To prevent such problems, the optical fiber blocking part (640) is implemented at the aforementioned location within the body (605) to prevent the optical fiber from entering in the direction of the optical fiber fixing part (650).

[0059] The optical fiber fixing part (650) is formed in a shape where a through hole is formed from the body (605) (e.g., It protrudes in the shape (etc.) and allows each optical fiber to be connected to pass through it. The optical fiber fixing part (650) can prevent the optical fibers from coming off by allowing the optical fibers to pass through the through hole it forms.

[0060] The optical fiber fixing part (650) is implemented between the adapter (660) or field type LC connector (680) and the optical fiber winding part (630) to fix the optical fibers that are wound in the optical fiber winding part (630) and then proceed to the adapter (660) or field type LC connector (680) for connection.

[0061] The adapter (660) is positioned in the central part of the body part (605) or adjacent thereto (within a preset radius) so that each field-type LC connector (680) can be coupled. The adapter (660) has a plurality of coupling structures (not shown) such that a field-type LC connector (680) can be coupled to it in a direction facing the optical fiber winding part (630) implemented at each location (one location close to the outflow / inflow part and one location far from the outflow / inflow part). The coupling structure (not shown) is implemented in a form complementary to the coupling part of the field-type LC connector (680). The adapter (660) couples one or more pairs of field-type LC connectors (680) facing each other, and is provided in the number of pairs of field-type LC connectors (680) to be coupled to couple the field-type LC connectors (680). Each adapter (660) is arranged side by side and couples one or more pairs of field-type LC connectors (680) facing each other.

[0062] The adapter fixing part (670) is provided in the number of adapters (660), and each adapter (660) is seated and receives an external force to move (rotate) or fix the adapter (660).

[0063] The adapter fixing part (670) is provided with a groove (673) having a width equal to the width of the adapter (660) at a pre-set position (e.g., its center) to seat the adapter (660). By seating the adapter (660), the adapter fixing part (670) minimizes (unintended) detachment of the adapter (660) and allows it to move together with the movement of the adapter fixing part (670).

[0064] The adapter fixing part (670) includes an adapter fixing part head (676) and a hinge joint part (679), and can rotate around one end. The structure of the adapter fixing part (670) and the body (605) is illustrated in FIG. 7.

[0065] FIG. 7 is an enlarged view of the adapter fixing part and body within the optical fiber coupling tray according to one embodiment of the present invention.

[0066] Referring to FIG. 7, the adapter fixing part (670) includes an adapter fixing part head (676) and a hinge connecting part (679).

[0067] The adapter fixing head (676) is implemented in a flat shape that is easy to receive external force at both ends of the adapter fixing part (670). The adapter fixing head (676) is implemented in a flat shape with a certain surface area so that it is easy for an operator to apply an external force to the adapter fixing head (676) to raise or lower.

[0068] A hinge joint (679) is implemented on one surface facing the hinge joint (715) of the body (605) within each end portion of the adapter fixing portion (670), thereby fixing the adapter fixing portion (670) or allowing the adapter fixing portion (670) to rotate. The hinge joint (679) is implemented in a protruding form facing the hinge joint (715) of the body (605) on the aforementioned surface, or is implemented in the form of a through hole on the aforementioned surface. At this time, the protruding diameter of the hinge joint (679) or the diameter of the through hole formed is implemented to be the same as that of the hinge joint (715). Accordingly, the hinge joint (679) can be coupled to and fixed with the hinge joint (715). Since the hinge joint (679) is implemented at each of the two ends of the adapter fixing part (670), if the hinge joints (679, 715) are joined at both ends, the adapter fixing part (670) is fixed completely without detaching. On the other hand, if the hinge joints (679, 715) are joined at only one end, the adapter fixing part (670) rotates with the joined part (part A in FIG. 7) as the axis of rotation (center axis). Accordingly, the adapter (660) seated thereon also rotates together with the adapter fixing part (670), so that one side of the adapter (660) is exposed upward. Accordingly, the operator can more easily connect the field-type LC connector (680) to one side of the adapter (660). Afterward, the operator can release the connection of the hinge joints (679, 715) of the part that became the axis of rotation and connect the hinge joints (679, 715) on the opposite side to rotate the opposite side in the same way. Accordingly, the operator can easily connect field-type LC connectors (680) with the adapter (660).

[0069] Meanwhile, the body (605) includes a protrusion (710) that protrudes vertically upward at intervals equal to the spacing at which the adapter (660) is placed, and includes a hinge joint (715) within the protrusion (710). The hinge joint (715) can be implemented in the form of a through hole when the hinge joint (679) is implemented in a protruding form, and in the opposite case, in a protruding form. Meanwhile, among the two hinge joints (679, 715), the hinge joint implemented in a protruding form may further include a groove (not shown) to have a stronger bonding force and a through hole. When the groove (not shown) is implemented and the other hinge joint is connected, it may be seated in the groove, making it more difficult to detach. In this way, the body (605) includes a protrusion (710) and a hinge joint (715) to fix one end or both ends of the adapter fixing part (670), and to fix the entire adapter fixing part (670) or allow it to rotate.

[0070] Referring again to FIG. 6, the field-type LC connector (680) secures the optical fiber to be connected to another optical fiber and contacts another connector (680) connected to a position facing or corresponding to itself within the adapter (660). The field-type LC connector (680) has the advantage of being able to connect and link quickly and easily at the installation site and does not require any additional processes for connection, etc. In addition, when coupled to the adapter (660), it contacts another connector (680) connected to a position facing or corresponding to itself and has the advantage of easily connecting the optical fibers connected to the connector. The field-type LC connector (680) secures the optical fiber (which flows into the outflow / inflow section (610, 615) and passes through the optical fiber winding section (630) and the optical fiber fixing section (650)) and allows it to be easily connected to another optical fiber simply by being coupled to the adapter (660).

[0071] The body coupling portion (690) is implemented at one end of the body (605), more specifically, at the end in the direction where the outflow / inflow portion (610, 615) is located, and is coupled with the coupling portion (224) within the tray connection body (220). More specifically, the body coupling portion (690) may be implemented as a protruding cylindrical shape, and the coupling portion (224) may be implemented as a through hole within the tray connection body (220). When the body coupling portion (690) and the coupling portion (224) are implemented in this manner, the optical fiber coupling tray (130) can be coupled with the tray connection body (220), and since both components (130, 220) are coupled in a hinge structure by the coupling portions (224, 690), they can rotate around the coupling portions (224, 690). If the optical fiber coupling tray (130) can rotate, and multiple optical fiber coupling trays (130) are coupled to each coupling part (224), it may be easier for an administrator to check and manage the optical fiber coupling trays (130) located at the bottom.

[0072] The above description is merely an illustrative explanation of the technical concept of the present embodiment, and a person skilled in the art to which the present embodiment belongs would be able to make various modifications and variations within the scope of the essential characteristics of the present embodiment. Accordingly, the present embodiments are intended to explain, not limit, the technical concept of the present embodiment, and the scope of the technical concept of the present embodiment is not limited by these embodiments. The scope of protection of the present embodiment shall be interpreted by the claims below, and all technical concepts within an equivalent scope shall be interpreted as being included within the scope of rights of the present embodiment.
