Description

Technical Field

[0001] This utility model relates to the field of fiber optic desktop box technology, specifically to a multifunctional miniature fiber optic desktop box. Background Technology

[0002] With the continuous advancement of fiber optic communication technology, Fiber to the Desktop (FTTD) is becoming increasingly widespread, forming an important component of modern office and home network environments. As the terminal equipment of an FTTD system, the fiber optic desktop box undertakes the crucial functions of securing the fiber optic cable, protecting fiber optic connectors, and enabling fiber optic access and port output. However, existing fiber optic desktop boxes have revealed several limitations in practical applications, specifically as follows: Limited fiber optic cable entry points: Traditional fiber optic desktop boxes typically only have fiber optic cable entry points located on the left, right, front, or back sides of the box. This lack of flexibility in cable entry and exit methods makes it difficult to adapt to the multi-directional cable entry needs in complex cabling environments. For example, when cabling in an office area, if the fiber optic cable needs to be introduced from under the desktop or from the side, the existing design requires additional holes or adjustments to the cabling path, increasing construction difficulty and cost.

[0003] Limited adapter types: Most fiber optic desktop boxes are only equipped with a single type of fiber optic adapter bayonet (e.g., only supporting SC adapters), and are not compatible with multiple types of adapters such as FC, LC, MTRJ, and E2000. When fiber optic patch cords require the use of other types of adapters, the existing equipment cannot meet the requirements, resulting in limited system scalability. This necessitates replacing the entire desktop box or adding an adapter conversion module, increasing maintenance complexity.

[0004] Fixed installation method: Existing fiber optic desktop box designs are mostly focused on desktop installation, lacking adaptability for wall mounting. In scenarios with limited space or where cabling needs to be concealed (such as conference rooms and home theaters), existing equipment cannot meet the requirements for wall mounting, limiting its application scope.

[0005] Inconvenient fiber optic management: The coiling and securing of optical fibers within desktop boxes lacks effective design, easily leading to fiber entanglement, excessively small bending radii, or damage from external forces. For example, if redundant optical fibers are not properly coiled, excessive bending may cause signal attenuation or even fiber breakage, affecting network stability.

[0006] Dust prevention and lack of labeling: Some fiber optic desktop boxes are not equipped with dustproof devices, allowing dust to easily enter the interface area, leading to poor contact or signal attenuation. At the same time, the lack of label strips or tag slots makes the identification and management of fiber optic lines difficult, increasing later maintenance costs.

[0007] To address the aforementioned issues, a new fiber optic desktop box technology solution is urgently needed. This solution should optimize the fiber optic cable routing layout, support multiple types of adapter mounting, be compatible with desktop and wall mounting, improve fiber optic management mechanisms, and enhance dustproof and labeling functions. This would improve the equipment's versatility, practicality, and maintenance efficiency, and meet the increasingly diverse application needs of FTTD systems. Summary of the Invention

The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0021] Example 1: A multifunctional miniature fiber optic desktop box includes a housing 1 with overall dimensions of 90*70*15.5mm. A top cover 2 is snapped onto the top port of the housing 1. A label-adhesive groove 201 is recessed on the upper surface of the top cover 2, where labels are adhered using adhesive. A transparent cover plate 3 is hinged to the upper surface of the label-adhesive groove 201, and the rear end face of the transparent cover plate 3 is snapped into the rear side of the inner cavity of the label-adhesive groove 201 to protect the labels. Three linearly arranged adapter mounting slots 101 are provided on the left side of the rear surface of the housing 1, allowing for the installation of SC adapters and LCS adapters, and controlling the protruding length of the adapters. The front middle section of the housing 1 has a reserved first cable locking groove 105, and the inner side of the groove is provided with a first optical cable input port 104 fixed to the inner side wall of the housing 1; the front side of the left side wall has a reserved fourth optical cable input port 110, and the inner side is provided with a fourth cable locking groove 111; the right side of the front side wall has a reserved third optical cable input port 108, and the inner side is provided with a third cable locking groove 109; the rear side of the right side wall has a reserved second optical cable input port 106, and the inner side is provided with a second cable locking groove 107. The first optical cable input port 104, the second optical cable input port 106, and the third optical cable input port 108 all receive 2*5mm optical cables, while the fourth optical cable input port 110 receives 4.5*8mm optical cables. The four optical cable input ports are pre-opened into the side wall of the housing 1. During use, the pre-connected portion is cut with pliers, and then plugged with the first plug 4, the second plug 5, the third plug 6, and the fourth plug 7, respectively. The outer surface of the plugs has multiple raised rings to increase the locking force. When using 2*3mm optical cables, the plugs are locked in for a seal. The first cable locking groove 105, the second cable locking groove 107, the third cable locking groove 109, and the fourth cable locking groove 111 are each composed of two serrated plates, providing a locking force of 40N.2Min on the optical cable. Two sets of cable winding plates 102 are fixed on the right side of the bottom side wall of the inner cavity of the housing 1. The plates are composed of four arc-shaped plates arranged in a ring. The upper part of the arc-shaped plates has a limit plate to restrict the optical cable from detaching. The design is suitable for φ0.9~φ3.0mm optical cables and 2*3mm optical cable coils, meeting the minimum bending radius requirement of G657A1 optical fiber coils, and can meet the requirement of 0.5M of 2*3mm optical cable coils. A spring-loaded fiber optic tube slot 103 is fixed on the left side of the bottom side wall of the inner cavity.

[0022] Example 2: A multifunctional miniature fiber optic desktop box, with housing 1 measuring 90*70*15.5mm. The top cover 2 is secured to the top port of housing 1 via snap-fit. After attaching a label to the label adhesive slot 201 on the top cover 2, the transparent cover 3 is closed and snapped in place. The adapter mounting slot 101 is located on the rear left side of housing 1. Adapters are installed as needed, with the exposed length controlled. Four fiber optic input ports are located on different side walls of housing 1. The first fiber optic input port 104, the second fiber optic input port 106, and the third fiber optic input port 108 receive 2*5mm fiber optic cables, and the fourth fiber optic input port 110 receives 4.5*8mm fiber optic cables. The pre-opening design facilitates selection of the interface according to the wiring direction. After cutting the pre-connected position, the corresponding plug is used to seal it. The first cable locking slot 105 and four other cable locking slots are composed of serrated plates to lock the fiber optic cables passing through the interface. The cable winding plate 102 is located on the bottom right side of the inner cavity of the housing 1, consisting of four arc-shaped plates arranged in a ring. A limit plate prevents the optical cable from detaching. It can wind φ0.9~φ3.0mm optical cables and 2*3mm optical cables, meeting various fiber winding needs and storing optical cables. The spring-loaded fiber fusion tube slot 103 is fixed on the bottom left side of the inner cavity of the housing 1, facilitating the placement of the fiber fusion tube.

[0023] Example 3: This multifunctional miniature fiber optic desktop box maintains a compact size of 90*70*15.5mm for its housing 1. The top cover 2 is snapped into place at the top port of housing 1. After the label is affixed to the label mounting slot 201, the transparent cover 3 secures it in place. The adapter is installed in the adapter mounting slot 101 on the rear left side of housing 1, ensuring proper protrusion. Four fiber optic input ports are located at different positions on housing 1. Depending on the actual fiber optic cable type (first port 104, second port 106, third port 108 for 2*5mm cables) and the cable direction (fourth port 110 for 4.5*8mm cables), a suitable interface is selected, and the pre-connected position is cut and sealed with a plug. Four cable locking slots secure the fiber optic cables, ensuring cable stability. The cable winding plate 102 at the bottom right of the inner cavity of housing 1, consisting of four arc-shaped plates in a circular array with a limit plate, allows for winding various fiber optic cable specifications, meeting normal winding and storage needs and facilitating future maintenance. The spring-loaded fiber optic tube slot 103 is located on the bottom left side of the inner cavity of the housing 1, providing a fixed position for the fiber optic tube.

[0024] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: Select the appropriate optical cable input port according to the actual wiring direction and the type of optical cable to be connected. The first optical cable input port 104, the second optical cable input port 106, and the third optical cable input port 108 of the housing 1 are suitable for receiving 2*5mm optical cables, and the fourth optical cable input port 110 is suitable for receiving 4.5*8mm optical cables. These optical cable input ports are pre-opened between themselves and the side wall of the housing 1. After determining the interface to be used, use pliers to cut off the pre-connection position of the interface so that the interface is in a state where optical cables can be connected. If an interface is not used temporarily, it can be left in its pre-connection state to prevent dust and other objects from entering. When the interface uses 2*3mm optical cables, the corresponding first plug 4, second plug 5, third plug 6, or fourth plug 7 is inserted into the interface to seal it. The multiple raised rings on the outer surface of the plug will increase the clamping force between it and the interface, which can prevent dust and ensure an aesthetically pleasing appearance. When 2*3mm optical cables are not used, the plugs can also play a certain role in preventing dust when the interface is not in use.

[0025] The selected optical cable is inserted into the housing 1 through the corresponding optical cable input port. After the optical cable is inserted, the corresponding cable locking slot is found according to the interface through which the optical cable is inserted. The first cable locking slot 105 corresponds to the first optical cable input port 104, the second cable locking slot 107 corresponds to the second optical cable input port 106, the third cable locking slot 109 corresponds to the third optical cable input port 108, and the fourth cable locking slot 111 corresponds to the fourth optical cable input port 110. Each of these cable locking slots consists of two serrated plates. The optical cable is placed between the two serrated plates, and the clamping action of the serrated plates forms a locking force of 40N.2Min on the optical cable, which fixes the optical cable and prevents it from loosening. For situations requiring fiber coiling, depending on the cable specifications, such as φ0.9-φ3.0mm or 2*3mm fiber optic cables, two sets of cable winding plates 102 can be used on the right side of the bottom sidewall of the inner cavity of housing 1. Each cable winding plate 102 consists of four arc-shaped plates arranged in a circular array. The fiber optic cable is wound around the arc-shaped plates, and a limiting plate fixed at the top of the arc-shaped plates prevents the cable from detaching from the cable winding plate 102. This cable winding plate 102 meets the minimum bending radius requirement for G657A1 fiber optic coiling and can accommodate up to 0.5M of 2*3mm fiber optic cable coiling. It satisfies both normal coiling needs and allows for cable storage for later maintenance. If fiber fusion is required, the fusion tube is placed in the spring-loaded fusion tube slot 103 fixed on the left side of the bottom sidewall of the inner cavity of housing 1. The spring-loaded fusion tube slot 103 secures the fusion tube, facilitating subsequent fusion work.

[0026] Regarding adapter installation, SC or LCS adapters are installed at three linearly arranged adapter mounting slots 101 on the left side of the rear surface of housing 1, according to actual needs. The protruding length of the adapter installation is carefully controlled to accommodate different connection requirements. Additionally, labels can be adhered to the recessed label mounting groove 201 on the upper surface of the top cover 2 using adhesive. This is used to record fiber optic cable information, connection status, etc., facilitating product tracking and maintenance management. After the labels are affixed, the transparent cover 3, hinged to the upper surface of the label mounting groove 201, is placed on top. The rear end face of the transparent cover 3 is snapped into place with the rear side of the inner cavity of the label mounting groove 201, protecting the labels and preventing wear or contamination.

[0027] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
