DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Reference Figures 1 to 12 As shown, an embodiment of the present invention provides a fixed sealing structure, which mainly includes a first sealing member 1 , a second sealing member 2 and a third sealing member 3 .

[0033] The first sealing member 1 has a plurality of first channels 11, which provide a path for subsequent objects (such as optical cables 7) to pass through, and play an important basic role in the entire sealing structure. The first channels 11 can be designed with specific sizes and shapes according to actual application scenarios to accommodate optical cables 7 of different specifications or other objects that need to be passed through.

[0034] The second seal 2 has a plurality of second channels 21, which correspond one to one with a plurality of first channels 11, and a third seal 3 is installed between each first channel 11 and the corresponding second channel 21; a first power is applied to the first seal 1 or the second seal 2 to realize that the first seal 1 and the second seal 2 move toward each other and are squeezed to form a sealed contact, and the first channel 11 and the corresponding second channel 21 are separated by the third seal 3 to form a double-channel structure for objects to penetrate; when an object is penetrated into the first channel 11 or the second channel 21, it and the third seal 3 are squeezed to contact the object to seal and fix the object; when no object is penetrated into the first channel 11 or the second channel 21, it and the third seal 3 are squeezed to close the channel.

[0035] In some practical applications, refer to Figure 8 As shown, the first seal 1 and the second seal 2 are both composed of a support 51 and a gel member 52. The gel member 52 is included outside the support 51. The gel member 52 is the part where the first seal 1 and the second seal 2 are in sealing contact. The overall structure of the third seal 3 is configured as a gel structural member. Since the gel member 52 usually has excellent elasticity, it can be deformed to a large extent when subjected to external forces such as squeezing and stretching, and can quickly return to its original shape once the external force disappears. Therefore, the gel member 52 can be used as a sealing material. The gel seal can be filled in the gaps between various components to play a sealing role, prevent the leakage of liquids, gases, etc., and ensure the normal operation of the equipment. When used for sealing and fixing the optical cable 7, it can effectively wrap the optical cable 7. At the same time, the gel member can also play the role of insulating seal.

[0036] Therefore, no matter when an object is inserted into the first channel 11 or the second channel 21, the third sealing member 3 will be in compression contact with the inserted object, thereby sealing and fixing the object, and preventing external dust, water vapor and other adverse factors from entering the channel to affect the performance of the object (such as the optical cable 7). Moreover, when no object is inserted into the channel (i.e., the first channel 11 or the second channel 21), the third sealing member 3 can close the channel under the compression of the first sealing member 1 and the second sealing member 2, and also plays a good sealing role, maintaining the integrity and sealing of the entire sealing structure.

[0037] When the optical cable 7 needs to be inserted into the optical cable joint box using the fixed sealing structure, it is mainly divided into dual-channel cable outlet and single-channel cable outlet.

[0038] If dual-channel cable output is to be achieved, two optical cables 7 can be inserted into two channels (i.e., two channels in the dual-channel structure separated by the third seal 3) respectively. When the optical cable 7 is inserted, under the action of the first power, the first seal 1 and the second seal 2 will move toward each other, gradually approach and finally squeeze to form a sealed contact. At this time, the third seal 3 installed between the first channel 11 and the second channel 21 begins to play a role. The third seal 3 will fit tightly on the surface of the optical cable 7. On the one hand, it fixes the optical cable 7 to keep it in a stable position in the channel. On the other hand, it prevents external factors from damaging the optical cable 7 through its own sealing performance.

[0039] If only a single channel is needed for cable output, then an optical cable 7 can be inserted into one of the channels, which will also achieve the sealing and fixation of the optical cable 7. Since there is no optical cable 7 inserted into the other channel, during the mutual squeezing process between the first seal 1 and the second seal 2, the channel without the optical cable 7 will be squeezed and closed by the third seal 3 and the corresponding first seal 1 or second seal 2, thereby ensuring the sealing of the entire sealing structure (if necessary, a dust plug can also be inserted into the channel without the optical cable 7, not shown in the figure, to ensure the sealing of the channel) to prevent dust, water vapor, etc. from entering the interior of the channel.

[0040] In summary, this fixed sealing structure can effectively prevent external dust, water vapor, impurities, etc. from entering the channel in the optical cable junction box through the mutual extrusion of the first seal 1 and the second seal 2 and the double sealing effect of the third seal 3 (both sealing and fixing the penetrated object and closing the channel when no object penetrates), thereby protecting the performance of the optical cable 7, reducing the transmission failure of the optical cable 7 caused by external factors, and extending the service life of the optical cable 7.

[0041] In addition, this fixed sealing structure can easily realize two modes: dual-channel cable outlet and single-channel cable outlet. In the actual laying and joint processing of optical cables 7, different scenarios may require different cable outlet methods. For example, in some complex network layouts, double-layer cable outlets may be required to connect different devices or lines respectively; in other relatively simple scenarios, single-layer cable outlets are sufficient to meet the needs. The sealing structure can flexibly select the cable outlet method according to the specific situation, which improves the adaptability of the optical cable junction box in different application scenarios.

[0042] Furthermore, when the optical cable 7 passes through any of the channels, the extrusion contact between the third sealing member 3 and the optical cable 7 can not only achieve sealing, but also firmly fix the optical cable 7 in the channel. This helps prevent the optical cable 7 from being displaced or loosened due to external forces (such as vibration, pulling, etc.) during use, ensures the stability and reliability of the connection of the optical cable 7, and thus ensures the stability of the signal transmitted by the optical cable 7.

[0043] In some practical applications, refer to Figures 2 to 3 As shown, the side ends of the third sealing member 3 close to the first channel 11 and the second channel 21 have notches 31 that fit the surface of the object. The notch 31 is mainly provided to cooperate with the first channel 11 and the second channel 21, and in particular, when used for sealing and fixing the optical cable 7, a channel that fits the optical cable 7 can be formed, thereby improving the sealing effect of the optical cable 7.

[0044] As for the connection relationship between the third seal 3 and the first seal 1 and the second seal 2, in some practical applications, the first seal 1 is provided with a first groove 12, which is cross-connected with the first channel; the second seal 2 is provided with a second groove 22, which is cross-connected with the second channel; when the first seal 1 and the second seal 2 are in sealing contact, the two ends of the third seal 3 are respectively embedded in the first groove 12 and the second groove 22.

[0045] Therefore, when the dual-channel cable is output, the first seal 1 and the second seal 2 need to be separated, and the third seal 3 needs to be removed, one of the optical cables 7 needs to be inserted into the second channel 21, and then one end of the third seal 3 needs to be embedded in the second slot 22 to achieve the initial positioning of one of the optical cables 7, and then the first seal 1 is moved closer to the second seal 2, and the third seal 3 is embedded in the first slot 12, and then the first seal 1 and the second seal 2 are continuously squeezed to complete the sealing and fixing of the two optical cables 7 in the dual channel; while when the single-channel cable is output , the staff does not need to remove the third seal 3, but only needs to separate the first seal 1 and the second seal 2. At this time, the third seal 3 is still located in the second slot 22 of the second seal 2. The staff can directly insert the optical cable 7 to be inserted into the first channel 11, and move the second seal 2 toward the first seal 1 again. Then, through the squeezing effect between the first seal 1 and the second seal 2, the optical cable 7 in the second channel 21 can be sealed and fixed, and the first channel 11 can be closed by the squeezing of the third seal 3 to ensure the sealing of the overall structure.

[0046] In this embodiment, the installation method of the third seal 3 improves the convenience of the staff's operation. When it is necessary to remove or install the optical cable 7, this structure makes the operation more direct and simple. In the case of a single-channel cable outlet, its convenience is more prominent. The optical cable 7 can be installed by simply separating the first seal 1 and the second seal 2, and there is no need to remove the third seal 3. This not only further simplifies the operating process, but also reduces the risk of damage to the sealing structure and the third seal 3 caused by frequent disassembly and installation, prolongs the service life of the sealing structure and various components, and also ensures that the subsequent re-sealing can be completed quickly and accurately, ensuring that the sealing effect is not affected.

[0047] In addition, the design of the third seal 3 being embedded in the groove enables it to better position and fix itself when the first seal 1 and the second seal 2 are in sealing contact, so that it can more effectively play its separation, sealing and fixing functions when realizing dual-channel cable output or sealing a channel without penetrating an object.

[0048] In other practical applications, refer to Figures 1 to 4 and Fig.12As shown, the third sealing member 3 is also plugged with a fixed card seat 4 in sealing contact therewith (the third sealing member 3 mentioned in the above embodiment is a gel member 52 structure, so depending on the properties of its material, the fixed card seat 4 can be wrapped to achieve sealing contact therewith), so that the object is fixed on the fixed card seat 4. Specifically, the two side ends of the fixed card seat 4 close to the first channel 11 and the second channel 21 are provided with a fixed position 41, so that the object in the corresponding side channel can be fixed on the fixed position 41 by a cable tie. It should be noted that the plug-in method of the third sealing member 3 and the fixed card seat can be a fixed plug-in method or a movable plug-in method.

[0049] In this embodiment, by setting a fixing position 41 on the fixing base 4 and fixing with a cable tie (of course, other fixing methods can also be used. In practical applications, cable ties are mostly used, mainly because cable ties are highly detachable and have low costs), the fixing effect of the object inserted into the channel is greatly enhanced. Compared with the above-mentioned embodiment, which only relies on the extrusion contact between the third sealing member 3 and the object for fixing, this additional fixing means enables the object to maintain its position more firmly in the channel, and even under the condition of external force (such as vibration, pulling, etc.), it can effectively reduce the possibility of displacement or loosening of the object, ensure the stability of the connection of the object (such as the optical cable 7), and thus ensure the stable transmission of the relevant transmission signal.

[0050] Reference Figures 1 to 12 As shown, an optical cable joint box is composed of an upper cover 61 and a lower cover 62, which cooperate to form a accommodating space for protecting the internal optical cable joints and related components. Among them, a first seal 1 is installed inside the upper cover 61, and a second seal 2 is installed inside the lower cover 62, and the two are sealed and connected through the above-mentioned specific fixed sealing structure. When the optical cable 7 is inserted as an object, it can effectively prevent external dust, water vapor and other adverse factors from entering the joint box, ensuring the stability of the connection of the optical cable 7 and the reliability of signal transmission.

[0051] The optical cable splice box is provided with an optical cable 7 entrance 611 at the bottom of the upper cover 61 and / or the lower cover 62. These optical cable 7 entrances 611 provide a passage for the optical cable 7 to enter and exit the splice box, facilitating the laying and connection of the optical cable 7, so that the optical cable 7 can be smoothly connected to the fixed sealing structure inside the splice box for corresponding processing and protection.

[0052] In some practical applications, a base plate 63 is also installed in the lower cover 62 to further support and assist in fixing related components. The fixed base 4 is an important component for additionally fixing the optical cable 7, and a detachable connection is adopted between the base plate 63. The fixed base 4 is detachably connected to the base plate 63. Specifically, the fixed base 4 also has a locking member 42 and an elastic arm 43. The locking member 42 is movably inserted into the locking groove 631 on the base plate 63, and the fixed base 4 moves with the locking member 42 in the locking groove 631 along the plug-in direction between the locking member 42 and the third sealing member 3, so as to realize the limiting of the locking member 42 in the direction perpendicular to the base plate 63 (the locking member 42 is adopted in the actual product as follows). Fig.12 The right-angled buckle plate shown); during the movement of the fixed card seat 4, the positioning portion 44 at the movable end of the elastic arm 43 moves from the state of elastically pressing against the bottom plate 63 and is embedded in the positioning groove 632 on the bottom plate 63, so as to realize the limitation of the fixed card seat 4 in the direction parallel to the bottom plate 63.

[0053] In this embodiment, the optical cable 7 is initially sealed and fixed by the fixed sealing structure, and the optical cable 7 is further stabilized by the precise limit connection between the fixed clamp 4 and the bottom plate 63, so that the optical cable 7 can be fixed in all directions and with high strength in the joint box. Even when subjected to external forces such as external vibration and pulling, the optical cable 7 can maintain its accurate position in the joint box, ensuring the stability of the connection of the optical cable 7, thereby ensuring the stable transmission of the communication signal.

[0054] The detachable connection between the fixed card holder 4 and the bottom plate 63 provides convenience for the installation and maintenance of the optical cable 7. When installing the optical cable 7, the fixed card holder 4 and the bottom plate 63 can be properly connected first, and then the optical cable 7 can be inserted into the fixed sealing structure and additionally fixed through the fixed card holder 4 (or the optical cable 7 can be inserted first and then connected to the fixed card holder 4). The whole process has clear steps and relatively simple operation. When the optical cable 7 needs to be maintained (such as inspection, replacement, etc.), the fixed card holder 4 can be easily removed from the bottom plate 63, and then the optical cable 7 can be operated accordingly. After completion, the fixed card holder 4 can be reinstalled, which will not cause too much damage to the structure of the entire junction box, which is conducive to quickly restoring the normal function of the junction box.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
