Description

Technical Field

[0001] The present invention relates to a horizontal pluggable optical cable splicing box, belonging to the technical field of OPGW optical cable splicing. Background Art

[0002] The OPGW optical cable includes an optical fiber part and a cable part, and is suitable for long-distance power transmission and communication. When erecting the long-distance OPGW optical cable, at corresponding positions, two sections of OPGW optical cables are spliced by means of fusion splicing to achieve long-distance power transmission and communication. With the increase in the number of optical fiber cores of the OPGW optical cable and the increase in external devices, the short-distance utilization frequency of optical fibers becomes higher. For example, if a short-distance device needs to be connected to a certain place of the long-distance OPGW optical cable, the OPGW optical cable needs to be disconnected. The construction process not only has a large workload, but also affects the normal power supply and communication. The existing optical cable fiber splitting and splicing box simply divides the optical cable into two parts without designing the optical fiber structure for the plug-in part, resulting in more labor costs when connecting short-distance devices.

[0003] If the plug-in module and the fusion splicing module are separately arranged, the device is too large in size, not easy to transport and install. And there is a problem of insufficient protection for the optical fiber interface. Summary of the Invention

[0004] In order to overcome the above problems, the present invention provides a horizontal pluggable optical cable splicing box, which includes a fusion splicing unit and a plug-in unit. Through the cooperation of the fusion splicing unit and the plug-in unit, the optical fibers in the OPGW optical cable can be pluggably connected.

[0008] Further, the plugging unit includes a plurality of optical fiber interfaces arranged on the side wall of the box body, the optical fiber interfaces are double-sided optical fiber interfaces, one side faces the inside of the box body, and the other side faces the outside of the box body, and the optical fibers on both sides of the same optical fiber interface are conducted; the preset optical fiber is plugged on the inner side of the optical fiber interface.

[0009] Further, fixing members are arranged at each optical cable through hole, the fixing members include two semi-circular fixing pieces; ears are arranged at both ends of the fixing piece, and screw holes are opened on the ears; one fixing piece is fixed at the optical cable through hole, and the other fixing piece is connected to the fixed fixing piece by screws to form an annular inner ring for clamping the OPGW optical cable to be spliced.

[0010] Further, after the preset optical fiber passes through the second optical fiber through hole, it is fixed by glue.

[0011] Further, the preset optical fibers are divided into two groups, A and B, the preset optical fibers in each group are fused with the optical fibers of the same section of OPGW optical cable to be spliced, and the number of the preset optical fibers in groups A and B is equal; the optical fiber interfaces are divided into two groups, A1 and B1, and the number of the optical fiber interfaces in groups A1 and B1 is the same, the preset optical fibers in group A are plugged into the optical fiber interfaces in group A1, and the preset optical fibers in group B are plugged into the optical fiber interfaces in group B1; a jumper wire is used to connect any optical fiber interface in group A1 and group B1 on the side of the optical fiber interface facing the outside of the box body to form a temporary long-distance communication trunk line.

Detailed Embodiment

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Refer to Figures 1-4 , a horizontal pluggable optical cable splicing box, comprising a box body 100, a splicing unit 200, a plugging unit 300, and a box cover 101 covering the upper part of the box body 100; two sides of one side wall of the box body 100 are provided with optical cable through holes 102; both sides of the bottom of the box body 100 are provided with strip-shaped clamping blocks 103, and a channel A is formed between the clamping blocks 103 and one side wall of the box body 100; two OPGW optical cables to be spliced enter the box body 100 through different optical cable through holes 102 respectively. The OPGW optical cable is divided into a cable part and an optical fiber part. The cable part of the OPGW optical cable is insulated. After the cable part of the OPGW optical cable passes through the channel A, it is spliced below the box body 100; the splicing unit 200 includes an annular cavity 201 arranged on the bottom surface of the box body 100, and first optical fiber through holes 202 are opened on both sides of the cavity 201; a plurality of second optical fiber through holes 203 are opened above the cavity 201, and pre-set optical fibers are arranged in each of the second optical fiber through holes 203; one end of the pre-set optical fiber is located outside the cavity 201, and the other end is located inside the cavity 201. An optical fiber connector is arranged at the end of the pre-set optical fiber located outside the cavity 201 and is plugged on the plugging unit 300; the optical fiber parts of the two OPGW optical cables to be spliced enter the cavity through different first optical fiber through holes 202 and are divided into two parts. One part is spliced with the optical fiber of the other OPGW optical cable to be spliced to form a long-distance communication trunk line, and the other part is spliced with the pre-set optical fiber to form a spare optical fiber.

[0025] Refer to Figure 2 , the optical fiber part of the OPGW optical cable to be spliced enters the splicing unit 200 in the B direction.

[0026] In at least one embodiment, the plugging unit 300 includes a plurality of optical fiber interfaces 301 arranged on the side wall of the box body 100. The optical fiber interfaces 301 are bilateral optical fiber interfaces, one side faces the inside of the box body 100, and the other side faces the outside of the box body 100. The optical fibers on both sides of the same optical fiber interface 301 are conducted; the pre-set optical fiber is plugged on the inward side of the optical fiber interface 301.

[0027] In at least one embodiment, fixing members 104 are arranged at each of the optical cable through holes 102. The fixing members 104 include two semi-circular fixing pieces 105; ear pieces 106 are arranged at both ends of the fixing pieces 105, and screw holes are opened on the ear pieces 106; one fixing piece 105 is fixed at the optical cable through hole 102, and the other fixing piece 105 is connected to the fixed fixing piece by screws to form an annular inner ring for clamping the OPGW optical cable to be spliced.

[0028] Since the OPGW optical cable is relatively heavy, there is a tensile force between two sections of OPGW optical cable to be joined. To eliminate the tensile force at the joint, the OPGW optical cable is fixed by the fixing member 104.

[0029] In at least one embodiment, after the pre - installed optical fiber passes through the second optical fiber through - hole 203, it is fixed by glue.

[0030] The cross - sectional area of the pre - installed optical fiber is much smaller than that of the second optical fiber through - hole 203. Therefore, fixing with glue can prevent the pre - installed optical fiber from being damaged and also prevent the pre - installed optical fiber from detaching from the second optical fiber through - hole 203 due to sliding or other reasons, which may cause inconvenience in subsequent installation.

[0031] In at least one embodiment, the pre - installed optical fiber is divided into two groups, A and B. The pre - installed optical fibers in each group are fusion - spliced with the optical fibers of the same section of OPGW optical cable to be joined, and the number of pre - installed optical fibers in groups A and B is equal; the optical fiber interface 301 is divided into two groups, A1 and B1, and the number of optical fiber interfaces in groups A1 and B1 is the same. The pre - installed optical fibers in group A are inserted into the optical fiber interfaces 301 in group A1, and the pre - installed optical fibers in group B are inserted into the optical fiber interfaces 301 in group B1; a jumper wire is used to connect any one of the optical fiber interfaces in group A1 and group B1 on the side of the optical fiber interface 301 facing the outside of the box body 100 to form a temporary long - distance communication trunk line.

[0032] In at least one embodiment, the pre - installed optical fiber is divided into two groups, A and B. The pre - installed optical fibers in each group are fusion - spliced with the optical fibers of the same section of OPGW optical cable to be joined, and the number of pre - installed optical fibers in groups A and B is equal; both sides of the optical fiber interface 301 can be inserted with two optical fibers. The two pre - installed optical fibers inserted into the optical fiber interface 301 facing the inside of the box body 100 come from groups A and B respectively; outside the box body 100, a strip wire is used to connect the two slots of the same optical fiber interface 301 to form a temporary long - distance communication trunk line.

[0033] After the splicing box connects two sections of OPGW optical cable, a long - distance communication trunk line is not formed, and there is actually a problem of waste of communication resources for the optical fibers that are not connected to the short - distance communication equipment part. Therefore, by using a jumper wire to connect the optical fibers from two sections of OPGW optical cable, a temporary long - distance communication trunk line is formed, which improves the utilization rate of communication resources. When accessing the short - distance communication equipment, only the corresponding jumper wire needs to be disconnected. The above two connection methods of the jumper wire actually correspond to different types of optical fiber interfaces, and the selection of the optical fiber interface is related to the communication interface of the short - distance communication equipment. Therefore, the two splicing methods of the jumper wire can be used for different working environments.

[0034] In at least one embodiment, a dust cover 302 is provided outside the box body 100, and the dust cover 302 covers above the optical fiber interface 301.

[0035] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
