Description

Technical Field

[0001] This utility model specifically relates to an optical cable splice protection device, belonging to the field of optical cable splice protection technology. Background Technology

[0002] An optical fiber cable is a communication cable assembly that uses optical fiber as the transmission medium. It consists of optical fibers, a plastic protective sheath, and a plastic outer sheath. It contains no metal and its main purpose is to transmit optical signals.

[0003] In optical cable splicing construction, tape is conventionally used to mechanically protect the splice. However, during subsequent cable laying and use, when the optical cable is subjected to wind vibration loads or axial tensile stress, the creep characteristics and insufficient interfacial adhesion of the tape material can easily lead to stress concentration effects, causing sheath peeling, which in turn leads to interruption or deterioration of optical signal transmission, thus affecting the reliability and stability of communication.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4As shown, an optical cable splice protection device includes a first protective cylinder 1, with a second protective cylinder 2 threadedly connected to one end of the first protective cylinder 1. Screws 3 are threaded through both sides of the ends of the first and second protective cylinders that are far apart from each other. A clamping plate 4 is rotatably connected to one end of the screws 3 at the first and second protective cylinders 1 and 2. A guide rod 5, which slides through the first and second protective cylinders 1 and 2, is fixedly connected to one side of the clamping plate 4. Conical spikes 6 are fixedly connected to the inner side of the clamping plate 4, and the conical spikes 6 are arranged in multiple sets at equal intervals. The first and second protective cylinders 1 and 2 provide a closed protective environment, enclosing the splice of the optical cable. The threaded connection facilitates installation and disassembly, while improving the sealing of the splice, reducing the ingress of external dust and moisture, and protecting the splice from environmental damage. The screws 3... The clamping force of the clamping plate 4 is adjusted by rotating the screw 3, which pushes the clamping plate 4 towards the optical cable, thereby achieving a tight clamping of the optical cable and ensuring the stable fixation of the optical cable at the splice. The clamping plate 4 is in direct contact with the optical cable and provides clamping force. By adjusting the screw 3, it can fit tightly against the optical cable to prevent the optical cable from loosening or shifting at the splice. The two sets of clamping plates 4 located on the first protective cylinder 1 and the second protective cylinder 2 can clamp the two sections of optical cable sheath that extend into the first protective cylinder 1 and the second protective cylinder 2. The guide rod 5 ensures the linear movement of the clamping plate 4 during the adjustment process. The conical spike 6 can slightly pierce the optical cable sheath to prevent the two sections of optical cable from sliding or separating inside the first protective cylinder 1 or the second protective cylinder 2 under external force, further enhancing the stability of the connection.

[0020] Furthermore, a conical pressure sleeve 7 is fixedly connected to one end of the first protective sleeve 1, and a conical connecting groove 9 is correspondingly opened inside the second protective sleeve 2. The conical pressure sleeve 7 and the conical connecting groove 9 are threaded together. Multiple sets of crimping grooves 8 are opened around the conical pressure sleeve 7, and a pressure block 10 is fixedly connected inside one end of the conical pressure sleeve 7. The multiple sets of conical pressure sleeves 7, together with the gaps provided by the multiple sets of crimping grooves 8, can evenly distribute pressure during the tightening process. When the conical pressure sleeve 7 is tightened, the pressure block 10 will provide additional clamping force to the optical cable splice.

[0021] Furthermore, spring posts 11 are fixed to both sides of the outer wall of the second protective cylinder 2. An L-shaped insert plate 12 is fixed to the moving end of the spring post 11. One end of the L-shaped insert plate 12 is slidably connected to the outer wall of the second protective cylinder 2. An insert block 13 is fixed to the end of the first protective cylinder 1 near the second protective cylinder 2. A slot is opened inside the insert block 13. The spring post 11 is used to facilitate the adjustment of the position of the L-shaped insert plate 12. After the L-shaped insert plate 12 is inserted into the slot, the elastic force of the spring post 11 can maintain the stable position of the L-shaped insert plate 12 and prevent it from being accidentally loosened. This ensures the connection stability between the first protective cylinder 1 and the second protective cylinder 2. The L-shaped insert plate 12 can be quickly inserted into the slot on the first protective cylinder 1 through the elastic force of the spring post 11, realizing the quick connection between the first protective cylinder 1 and the second protective cylinder 2 and preventing the first protective cylinder 1 and the second protective cylinder 2 from rotating randomly after the connection is complete.

[0022] Furthermore, sealing rings 14 are installed inside the ends of the first protective cylinder 1 and the second protective cylinder 2 that are far apart from each other, and winding parts 15 are fixedly connected to the ends of the first protective cylinder 1 and the second protective cylinder 2 that are far apart from each other. The sealing rings 14 are used to fill the gap after the first protective cylinder 1 and the second protective cylinder 2 are connected, further enhancing the sealing performance, reducing the entry of external moisture, dust and other substances into the cylinder, and protecting the optical cable splice from environmental damage. The winding parts 15 provide a flat surface, which is convenient for wrapping tape after installation. The wrapping of tape can further strengthen the connection between the cylinder and the optical cable, prevent loosening, and provide an additional protective layer to prevent dust and other substances from entering the cylinder.

[0023] Furthermore, both sides of the L-shaped insert plate 12 are fixed with arc-shaped spring pieces 16, which are made of elastic material. When the L-shaped insert plate 12 is fully inserted into the slot, the arc-shaped spring pieces 16 will elastically deform inward, increasing the friction with the inner wall of the slot, thereby preventing the L-shaped insert plate 12 from accidentally coming loose.

[0024] Furthermore, a conical guide ring 17 is fixed inside the second protective cylinder 2 near the conical connecting groove 9, with the smaller end of the conical guide ring 17 connected to the conical connecting groove 9; the conical guide ring 17 is used to facilitate personnel to introduce the optical cable into the second protective cylinder 2.

[0025] Working steps: First, pass the two optical cable segments through the first protective cylinder 1 and the second protective cylinder 2 respectively. Then, use a fusion splicer to fuse the two optical cable cores. Afterward, rotate the first protective cylinder 1 and the second protective cylinder 2 to make them threaded together. During this process, the inner diameter of the thinner end of the tapered connecting groove 9 is smaller than the outer diameter of the corresponding end of the tapered pressure sleeve 7. This causes the tapered pressure sleeve 7 to be squeezed outwards when tightened, and the crimping groove 8 provides deformation space for it. When the first protective cylinder 1 and the second protective cylinder 2 are completely connected, this... At the same time, the conical pressure sleeve 7 is also in a tightened state. At this time, the pressure block 10 will provide additional clamping force to the optical cable to ensure stability. Then, the clamping plate 4 is adjusted by rotating the screw 3 so that the clamping plate 4 tightly clamps the optical cable. The conical spike 6 slightly pierces the optical cable sheath to increase friction. Then, using the elastic force of the spring column 11, the L-shaped insert 12 is quickly inserted into the slot of the insert block 13. The arc-shaped spring piece 16 increases friction to prevent loosening. The sealing ring 14 fills the gap and enhances the sealing effect. Finally, tape is wrapped around the winding part 15 to further strengthen the connection and provide an additional protective layer.
