Description

Technical Field

[0001] This invention relates to a waterproof push-pull closure with a structure that allows for disassembly and assembly of the object being installed. The closure is waterproof due to its sealed structure. When a fiber optic connector is inserted, the closure can be easily fixed and released (locked and unlocked) simply by moving it forward or backward. Background Technology

[0002] Optical cable enclosures are sealed boxes used to protect optical fiber splices or branches.

[0003] Optical cable enclosures are typically installed on utility poles and in locations where optical cables are branched. They branch off a portion of the optical cable and install it inside, serving to distribute the cable to multiple locations.

[0004] However, typically, for such existing enclosures, the fiber optic connector is mounted on the enclosure, and to prevent it from being disassembled to the outside, a separate fixing unit is used around the insertion hole where the fiber optic connector is inserted. The fiber optic connector is then fixed to the device by rotating screws.

[0005] This structure introduces additional tedious work for staff every time they install and remove the fiber optic connectors, increasing not only the overall price of the device but also adding complexity to the internal structure.

[0006] Therefore, there is a real need to develop a device that allows for easy and simple insertion and removal of fiber optic connectors from the outside of the enclosure, even without such a separate fixing unit or device.

[0058] H: Hole Detailed Implementation

[0059] Before describing several embodiments of the present invention, it is understood that the application of the present invention is not limited to the detailed description of the structure and arrangement of the structural elements described in the following detailed description or shown in the figures. The present invention can be implemented and practiced in other embodiments and can be carried out in various ways. Furthermore, the expressions and terminology used in the present invention relating to the orientation of devices or elements (e.g., "front", "back", "up", "down", "top", "bottom", "left", "right", "lateral") are used for the purpose of simplifying the description of the present invention, and the related devices or elements do not simply mean having a specific orientation. Moreover, terms such as "first" and "second" are used only for description and do not indicate relative importance or intent as used in the present invention and the scope of the claims.

[0060] The present invention has the following features in order to achieve the stated objective.

[0061] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in this specification and the scope of the invention claims should not be limited to their general or dictionary meanings, but rather should be interpreted according to the meanings and concepts consistent with the technical concept of the present invention, based on the principle that inventors may appropriately define terms and concepts in order to explain their invention through the most preferred method.

[0062] Therefore, the embodiments described in this specification and the structures shown in the figures are only the most preferred embodiments of the present invention, and are not intended to replace the technical concept of the present invention. Therefore, it should be understood that at the time of this application, there may be a variety of equivalent technical solutions or modifications that can replace these.

[0063] The following is for reference Figures 1 to 17 The waterproof push-pull closure 300 with convenient locking and unlocking function of fiber optic connector according to a preferred embodiment of the present invention will be described in detail.

[0064] Therefore, the waterproof push-pull closure 300 of the present invention, which has convenient locking and unlocking functions for fiber optic connectors, includes a closure 300, a fiber optic connector 100, a fiber optic connector locking device 200, and an optical adapter 310.

[0065] The enclosure 300 is installed in a detachable manner on the object containing the optical cable C. After a single optical fiber connector 100 is inserted into the enclosure 300 through the insertion hole 307, it branches into multiple ports inside the enclosure 300 and distributes them to multiple places of use (home, etc.). The entire enclosure 300 is a sealed structure, thus having the effect of waterproofing from the outside.

[0066] When the closure 300 is installed on an optical cable on a pole, it can be configured as a first fixing part 330 in the form of a ring that can be set by clamping the closure 300 onto the main optical cable C. When it is installed on a pole, it can be configured as a second fixing part 340 in the form of a belt that can surround the object to be installed according to the outer circumference diameter and suspend the closure 300.

[0067] Furthermore, in the case of the closure 300, in order to seal the closure 300, a gasket 303 can be used between the body 301a constituting the closure 300 and the cover 301b to achieve fastening. In the factory, after the components are installed inside the body 301a of the closure 300, it can be manufactured as an integral unit by an overmold method.

[0068] The fiber optic connector 100 is selectively inserted into a plurality of insertion holes 307 formed in the enclosure 300, thereby branching into multiple cables in a manner that allows a single optical cable C to be used in multiple locations within the enclosure 300.

[0069] This fiber optic connector 100 includes a connector body 110, a sealing component 120, an insertion slot 130, a height difference portion 140, and a dust cover portion 116.

[0070] The connector body 110 is disposed outside the aforementioned closure 300 (branching device) and other devices. An optical adapter 310 is inserted into the insertion hole 307 of the connector body 110 and connected inside the closure 300. For this purpose, a plug 114 is formed at one end, a ferrule 113 with an optical fiber is formed at the center of one end, and a protective portion 117 is formed from the middle end to the rear end to protect the outer periphery.

[0071] Furthermore, one end of the fiber optic connector 100 is provided with a dust cover 116 that is detachably mounted along the length direction. A ring 115 is formed at one end of the dust cover 116 to fix the metal wire for cable laying. This can protect the sealing member 120, the insertion groove 130, and the height difference portion 140 from the outside. The dust cover 116 is fastened to the protrusion 118 of the fiber optic connector body 110 in the form of a bayonet.

[0072] The sealing component 120 is a ring made of elastic rubber or the like, which has the following waterproof function: after a placement groove 121 is formed on the outer periphery of the middle end of the connector body 110, it is inserted into such a placement groove 121. Thus, the interior of the insertion hole 307 contacts the outer periphery of the sealing component 120 and prevents water vapor or moisture from flowing into the insertion hole 307 into which the connector body 110 is inserted.

[0073] The insertion slot 130 is formed on the outer periphery between the plug 114 and the sealing member 120 in the connector body 110, thereby engaging with the fiber optic connector locking device 200 formed on the bottom surface of the insertion hole 307 for corresponding installation and fixation. The height difference portion 140 is the locking portion of the fiber optic connector locking device 200 such that the first diameter 131 of the connector body 110 at the front end of the insertion slot 130 is relatively smaller than the second diameter 132 of the connector body 110 at the rear end of the insertion slot 130, thus forming a height difference between them.

[0074] The insertion slot 130 includes: a first shoulder 134, which is vertically recessed from a first diameter 131; and an inclined surface 133, which forms an oblique shape from the first shoulder 134 to a second diameter 132, with the diameter gradually increasing, thereby forming a triangular insertion slot 130. The plunger 30 formed in the fiber optic connector locking device 200 will be described in detail below when describing the fiber optic connector locking device 200. The upper surface of the plunger 30 is formed in a shape corresponding to the insertion slot 130, thereby correspondingly inserting into the insertion slot 130 and preventing the connector body 110 from disengaging from the insertion hole 307.

[0075] First, the fiber optic connector locking device 200 located inside the plunger 30 has the following structure: when pressed once, the plunger 30 formed on the upper surface of the fiber optic connector locking device 200 will rise, and when pressed again, it will fall, thus repeatedly raising and lowering. For this plunger raising and lowering structure of the fiber optic connector locking device 200, the internal structure used for this operation can be changed in various ways according to the user's embodiment, but is not limited to a certain structure.

[0076] The fiber optic connector 100 and the enclosure 300, based on the aforementioned structure, operate in the following first and second scenarios: In the first scenario, initially, with the plunger 30 pressed, the fiber optic connector 100 contacts the upper surface of the plunger 30 and advances, causing the second diameter 132 portion to correspond to and press the plunger 30 to raise it. Then, by retracting the fiber optic connector 100, the plunger 30 is inserted into the insertion slot 130, and the fiber optic connector 100 remains fixed in position within the insertion hole 307. In the second scenario, the first scenario... Furthermore, with the fiber optic connector 100 inserted into the insertion hole 307, the fiber optic connector 100 is further advanced so that the second diameter 132 portion presses the plunger 30 back down to its initial position. This prevents the first diameter 131 and second diameter 132 portions of the fiber optic connector 100 from getting stuck in the plunger 30. Thus, by retracting the fiber optic connector 100, the fiber optic connector 100 can be separated from the insertion hole 307. Through the forward and backward movement of the fiber optic connector 100, the plunger 30 performs a lifting and lowering linkage operation, thereby allowing the fiber optic connector 100 and the plunger 30 to be disassembled and assembled.

[0077] The fiber optic connector locking device 200 is a locking unit that is disposed inside the enclosure 300 on the bottom surface of the insertion hole 307. It can be raised and lowered by moving the installed fiber optic connector 100 forward and backward, thereby installing the fiber optic connector 100 in the enclosure 300 and releasing it from it.

[0078] The fiber optic connector locking device 200 includes an outer cover 10, an elastic component 20, a plunger 30, a heart-shaped cam 40, and a stick 50.

[0079] The outer cover 10 has a quadrilateral tube shape with a relatively long length along the length direction, and is divided into multiple spaces in such a way as to form multiple vertically arranged spaces 11 in the length direction. The vertically arranged spaces 11 form openings 12 with front openings in a way that communicates with the interior, and have opening holes 13 formed by perforation at the lower front end.

[0080] The elastic component 20 is a spring that is upright installed in each of the vertically installed spaces 11.

[0081] The plungers 30 are each erected within the vertical space 11, with a central hole H formed to allow the elastic member 20 to be inserted and installed in the center. Thus, each plunger 30 is erected in the vertical space 11 with a portion of the elastic member 20 inserted, allowing it to rise and fall. In other words, the plunger 30 has a repetitive rising and falling structure that rises when pressed once and falls when pressed again.

[0082] Furthermore, this plunger 30 has a heart-shaped cam 40 with a heart-shaped recess on the side (front surface) corresponding to the opening hole 12.

[0083] The heart-shaped cam 40 has a concave shape on the left side in the shape of a "C" and a concave shape on the right side in the shape of an inverted "C". The overall shape is heart-shaped. After the insertion protrusion 53 of the rod 50 is inserted into the concave part 41 of the heart-shaped cam 40, it rotates clockwise along the concave part 41.

[0084] Meanwhile, the plunger 30 also has a placement groove 31 and a suspension part 34 formed on its upper surface.

[0085] The placement groove 31 is recessed in a semi-circular shape on the upper surface of the plunger 30 in the width direction of the outer cover 10 (the forward and backward direction of the fiber optic connector 100 (the insertion direction of the fiber optic connector 100)). The lower part of the outer periphery of the fiber optic connector 100 with a circular cross-section is in corresponding contact with this placement groove 31 and can be horizontally inserted in the forward and backward direction orthogonal to the length direction of the outer cover 10.

[0086] The suspension part 34 is formed in a semi-circular shape protruding from the middle of the placement groove 31 in a left-right direction orthogonal to the forward and backward direction of the fiber optic connector 100. An insertion surface 32 with an oblique line is formed on the front surface, and a locking part 33 forming a right angle with the placement groove 31 is formed on the rear surface.

[0087] One end of the rod 50 is inserted into the front surface side opening 13 of the outer cover 10, and the other end forms an insertion protrusion 53 that is inserted into the heart-shaped cam 40. Thus, whenever the plunger 30 is pressed, the insertion protrusion 53 moves clockwise along the recessed portion 41 of the heart-shaped cam 40 and repeatedly performs the work of alternately fixing the upper end point A and the lower end point B of the heart-shaped cam 40, thereby fixing the rising and falling positions of the plunger 30.

[0088] Therefore, the rod 50 includes a horizontal rod 53, a vertical rod 52, and an insertion protrusion 53.

[0089] The horizontal rod 53 is inserted into the opening 13 and can rotate left and right on its bottom surface within the vertical setting space 11. When inserted horizontally, it can be disassembled to the outside. Therefore, it should be inserted in an oblique shape within the vertical setting space 11. The vertical rod 52 is a protrusion that extends vertically from one end of the horizontal rod 53 toward the opening 12, forming a "└" shaped cross-section together with the horizontal rod 53. The insertion protrusion 53 is inserted into the heart-shaped cam 40 at the end of the vertical rod 52, thereby allowing it to move along the recessed portion 41 of the heart-shaped cam 40.

[0090] First, the shape of the fiber optic connector 100, which contacts the upper surface of the plunger 30 described in this invention and moves horizontally forward and backward, generally has a circular cross-sectional structure. It has an insertion groove 130 formed on its outer periphery so as to be inserted into the suspension portion 34 of the plunger 30. Based on the insertion groove 130, the outer periphery diameter (first diameter 131) of the front end side of the insertion head portion is smaller than the outer periphery diameter (second diameter 132) of the rear end side of the insertion groove 130.

[0091] Furthermore, this fiber optic connector 100 is horizontally mounted on a closure 300 forming a separate insertion hole 307 for inserting the fiber optic connector 100. The fiber optic connector locking device 200 of the present invention is used by providing a position within this closure 300 corresponding to the outer periphery of the fiber optic connector 100. As described above, as long as the outer periphery of the fiber optic connector 100 has a structure for insertion in a form orthogonal to the plunger 30 in this fiber optic connector locking device 200 of the present invention, the closure 300 can be a variety of devices, not limited to any particular type or field; other devices besides the closure can also be used instead.

[0092] Based on this fiber optic connector locking device 200, the fixing and releasing operations (first case and second case) of the fiber optic connector 100 within the insertion hole 307 by moving forward and backward are described below.

[0093] With the insertion protrusion 53 located at the upper end point A and pressing the plunger 30, if the fiber optic connector 100 contacts the upper surface of the plunger 30 and moves forward, after the first diameter 131 portion of the fiber optic connector 100 passes horizontally on the upper surface of the plunger 30, when the second diameter 132 portion arrives at the position of the plunger 30, this second diameter 132 portion corresponds to the plunger 30 and presses the plunger 30.

[0094] By pressing, the insertion protrusion 53 rotates in a reverse C-shape and moves toward the lower end point B located at the center of the lower side of the heart-shaped cam 40. In response, the plunger 30 will rise due to the restoring force of the compressed elastic member 20, and the suspension part 34 will be located at a higher position than the upper surface of the outer cover 10.

[0095] Then, the fiber optic connector 100 is retracted into the insertion slot 130 so that the insertion slot 130 of the outer periphery of the fiber optic connector 100 is inserted into the suspension part 34, so that the suspension part 34 is inserted into the insertion slot 130, thereby keeping the fiber optic connector 100 fixed in the plunger 30 (first case, when the fiber optic connector 100 is installed and fixed).

[0096] Following the first scenario, when disassembling the fiber optic connector 100, if the fiber optic connector 100 is advanced such that the second diameter 132 portion is positioned at the suspension portion 34, the second diameter 132 portion represses the plunger 30. In response, the insertion protrusion 53 moves clockwise in a C-shape and towards its upper endpoint A, located at the center of the upper side of the heart-shaped cam 40. This recompresses the elastic member 20, causing the plunger 30 to descend. As described above, if the plunger 30 descends, and the suspension portion 34 forms the same horizontal line as the upper surface of the outer casing 10 or is positioned at a higher level, the fiber optic connector 100 is retracted and separated in such a way that it completely detaches from the upper surface of the plunger 30 (second scenario, when the fiber optic connector 100 is disassembled during installation).

[0097] The optical adapter 310 is disposed within the enclosure 300 at each rear end of the insertion hole 307 and is connected to the optical fiber connector 100 respectively.

[0098] The optical adapter 310 includes an adapter 311, an adapter cover 320, a connecting pin 313, and an elastomer 314.

[0099] The adapter 311 is horizontally disposed in the setting groove formed at the rear end of the insertion hole 307, and is configured such that the extensions 312 protruding on both sides are disposed vertically, and the front end is connected to the fiber optic connector 100.

[0100] The adapter cover 320 is assembled on the upper part of the setting groove so that the extension 312 is correspondingly set to form the groove 321.

[0101] The connecting pin 313 has one end connected to the extension 312 in the groove 321 and the other end fixed to the adapter cover 320. The elastic body 314 uses a spring or the like with elasticity and is located on the outer periphery of the connecting pin 313 in the groove 321 so that the adapter 311 is always pushed forward in a position connected to the fiber optic connector 100.

[0102] The working relationship between the optical adapter 310, the optical fiber connector 100, and the optical fiber connector locking device 200 is explained as follows.

[0103] Work through the following first and second cases (the... Figure 5 and Figure 6 The operation of parts (A) to (H) shown is continuous and repetitive: In the first case, initially, with the plunger 30 pressed ( Figure 6 (E) section), insert fiber optic connector 100 into insertion hole 307 ( Figure 6The (F) portion of the fiber optic connector 100 is brought into contact with the upper surface of the plunger 30 and advanced, such that the elastic body 314 extending from the outer periphery of the optical adapter 310 connected to the fiber optic connector 100 is pressed and pushed rearward, thereby advancing the second diameter 132 portion of the fiber optic connector 100 after the plunger 30 is correspondingly positioned and the plunger 30 is pressed to raise it. Figure 6 (G) section), the elastomer 314 returns to its original shape and retracts the optical adapter 310 and the fiber optic connector 100 so that the plunger 30 is correspondingly inserted into the insertion slot 130 ( Figure 6 (H) portion), and maintains the fiber optic connector 100 in a fixed position within the insertion hole 307. Figure 5 (Part A)), in the second case, through the first case, in the state where the fiber optic connector 100 is inserted into the insertion hole 307 ( Figure 5 (A) portion), so that the fiber optic connector 100 is advanced again toward the optical adapter 310 side within the insertion hole 307, such that the elastic body 314 extending from the outer periphery of the optical adapter 310 connected to the fiber optic connector 100 is pressed and pushed rearward. Figure 5 (B) portion), thereby, the second diameter 132 portion of the fiber optic connector 100 represses the plunger 30 to cause the plunger 30 to descend to its initial position ( Figure 5 (C) portion), thereby preventing the first diameter 131 and second diameter 132 portions of the fiber optic connector 100 from getting stuck in the plunger 30, thus allowing the fiber optic connector 100 to retract and separate from the insertion hole 307. Figure 5 Part (D) and Figure 6 (E) section), through the lifting and lowering linkage of the plunger 30 based on the forward and backward operation of the fiber optic connector 100, the fiber optic connector 100 and the plunger 30 can be disassembled and assembled.

[0104] As described above, although the present invention has been illustrated by way of limited embodiments and drawings, the present invention is not limited thereto.

9. The waterproof push-pull closure with convenient locking and unlocking function for fiber optic connectors as described in claim 8, characterized in that, An insertion slot (130) is formed in the fiber optic connector (100), the insertion slot (130) being formed on the outer periphery such that the suspension part (34) is correspondingly inserted. The second diameter (132) on the rear end side of the insertion slot (130) is larger than the first diameter (131) on the front end side of the insertion slot (130).

10. The waterproof push-pull closure with convenient locking and unlocking function for fiber optic connectors according to claim 1, characterized in that, The fiber optic connector (100) has a structure that allows the plunger (30) formed in the fiber optic connector locking device (200) to repeatedly rise and fall in a button-like manner. Work under the following first and second scenarios: In the first case, initially, with the plunger (30) pressed, the fiber optic connector (100) is inserted into the insertion hole (307) so that it contacts the upper surface of the plunger (30) and advances, so that the elastic body (314) of the outer periphery of the optical adapter (310) connected to the fiber optic connector (100) is pressed and pushed backward, thereby aligning the second diameter (132) portion of the fiber optic connector (100) with the plunger (30) and pressing the plunger (30) to raise it. Afterward, the elastic body (314) returns to its original state, causing the optical adapter (310) and the fiber optic connector (100) to retract so that the plunger (30) is inserted into the insertion slot (130), and the fiber optic connector (100) remains in a fixed position within the insertion hole (307). In the second case, following the first case, with the fiber optic connector (100) inserted into the insertion hole (307), the fiber optic connector (100) is moved forward again towards the optical adapter (310) within the insertion hole (307). This causes the elastic body (314) on the outer periphery of the optical adapter (310) connected to the fiber optic connector (100) to be pressed and pushed backward. This causes the second diameter (132) portion of the fiber optic connector (100) to be pressed again, causing the plunger (30) to descend to its initial position. This prevents the first diameter (131) and second diameter (132) portions of the fiber optic connector (100) from getting stuck in the plunger (30), thereby allowing the fiber optic connector (100) to retract and separate from the insertion hole (307). The forward and backward movement of the fiber optic connector (100) causes the plunger (30) to move up and down in a coordinated manner, thereby allowing the fiber optic connector (100) and the plunger (30) to be disassembled and assembled.

11. The waterproof push-pull closure with convenient locking and unlocking function for fiber optic connectors according to claim 1, characterized in that, In order to seal the closure (300), a gasket (303) can be used between the body (301a) constituting the closure (300) and the cover (301b) to achieve fastening.
