Description

Technical Field

[0001] The utility model relates to the technical field of optical cable connection, in particular to an anti-falling connecting optical cable. Background Art

[0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a sheath as transmission media and can be used individually or in groups. When installing an optical cable, if the length is insufficient, the ends of the two cables will need to be fused to ensure that the corresponding length is reached.

[0003] After connecting the optical cables, the staff simply put the heat shrink tube on the fusion joint to protect the connection joint. However, since the fusion joint of the optical cable is relatively fragile and the length of the optical cable is relatively long, the optical cable is easily entangled and bent during use. As the use time increases, the heat shrink tube is easily broken, which in turn causes the optical cables to fall off, which increases the maintenance cost of the optical cables during use. Therefore, we propose an anti-falling connecting optical cable to solve the above problem. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , an anti-falling connecting optical cable, including an optical cable body 1, the optical cable body 1 is provided with two groups, and the two groups of optical cable bodies 1 are connected to each other through a heat shrink sleeve 2, the connection method between the optical cable body 1 and the heat shrink sleeve 2 is the existing technology, and no more details are given here, the upper and lower ends of the heat shrink sleeve 2 are symmetrically distributed with support rods 3, and the sides of the support rods 3 are symmetrically inserted with insertion rods 4, the ends of the insertion rods 4 are connected with sleeve blocks 5, and the interior of the upper sleeve block 5 is inserted with a connecting rod 6, and the bottom end of the connecting rod 6 is connected to the lower sleeve block 5 Then, a first spring 8 is sleeved on the outer side of the connecting rod 6, and the upper and lower ends of the first spring 8 are fixedly connected to the upper and lower layers of the sleeve blocks 5. Through the cooperation between the connecting rod 6 and the first spring 8, the spacing between the upper and lower layers of the sleeve blocks 5 can be adjusted to ensure that they can slide normally on the outer sides of the optical cable body 1 and the heat shrink sleeve 2. After the sliding is completed, the inner wall of the sleeve block 5 is engaged with the outer side of the optical cable body 1 and is limited by the heat shrink sleeve 2 with a larger outer diameter to effectively prevent the sleeve block 5 from shifting left and right.

[0023] Further, see Figure 2 and Figure 3 It can be seen that the upper and lower sides of the sleeve blocks 5 are respectively glued with rubber plates 9 on the sides close to each other, and the outer sides of the rubber plates 9 are provided with anti-slip grooves. When in use, the reliability of the sleeve blocks 5 when they are engaged on the outer side of the optical cable body 1 can be improved through the mutual cooperation of the rubber plates 9 and the anti-slip grooves.

[0024] Further, see Figure 2 and Figure 4 It can be known that movable grooves 10 are symmetrically opened at the left and right ends of the support rod 3, and the inside of the movable grooves 10 are clamped with fixed blocks 11, and the sides of the fixed blocks 11 are fixedly connected to the insertion rod 4. When in use, the combined length of the support rod 3 and the insertion rod 4 can be adjusted by the mutual cooperation of the movable grooves 10 and the fixed blocks 11, so as to adjust the distance between the left and right side sleeve blocks 5, so that it can be adjusted according to the length of the heat shrink sleeve 2.

[0025] Further, see Figure 4It can be known that a slot is provided inside the fixed block 11, and a second spring 12 is vertically connected to the inner wall of the slot, the other end of the second spring 12 is connected to a pushing block 13, and a locking block 14 is connected to the side of the pushing block 13, and the other end of the locking block 14 passes through the inner wall of the slot, and the interior of the support rod 3 is horizontally and equidistantly provided with locking grooves that are compatible with the locking block 14. When in use, when it is necessary to move the insertion rod 4, the staff can manually squeeze the locking block 14 so that it is embedded in the slot provided inside the fixed block 11, and then the staff can pull the insertion rod 4 to make it slide inside the movable slot 10, and through the mutual cooperation of the pushing block 13 and the locking block 14, the position of the moved sleeve block 5 can be limited, thereby preventing the sleeve block 5 from moving easily when it is engaged.

[0026] Further, see Figure 4 It can be known that the end of the support rod 3 is symmetrically connected with a guide block 15, and the guide block 15 is set to an L-shaped structure. The side wall of the insertion rod 4 is provided with a slideway adapted to the guide block 15. Through the mutual cooperation of the guide block 15 and the slideway, the guidance of the insertion rod 4 during the movement process can be achieved, so that the position of the locking block 14 and the position of the locking slot always correspond to each other. Since the guide block 15 is set to an L-shaped structure, it can be easily locked inside the insertion rod 4.

[0027] Further, see Figure 1 and Figure 2 It can be known that the upper and lower groups of support rods 3 are connected by spring sheets 16, and the spring sheets 16 are arranged as an arc structure. By using multiple groups of spring sheets 16 arranged as an arc structure, when the upper and lower groups of sleeves 5 are forced to move away from each other, the spring sheets 16 of the arc structure can be deformed. After the sleeve 5 is moved to a suitable position, the setting of the spring sheets 16 can effectively ensure the tightness of the sleeve 5 in the side of the optical cable body 1.

[0028] Further, see Figure 3 It can be known that the top end of the connecting rod 6 is connected to the limiting block 7, and the transverse section of the limiting block 7 is larger than the cross-sectional area of ​​the connecting rod 6. The limiting block 7 with a larger cross-sectional area can block the upper sleeve block 5 from sliding out of the connecting rod 6.

[0029] Working principle: When the utility model is in use, the staff can first put the heat shrink sleeve 2 and the left and right groups of blocks 5 on the outside of one group of optical cable bodies 1, and then use the hot melt machine to weld the optical cable bodies 1. After the welding is completed, the heat shrink sleeve 2 is pushed to the welding position and the heat shrink sleeve 2 is heated and fixed. After the heat shrink sleeve 2 is fixed, the staff can pull the upper and lower layers of blocks 5, so that the distance between the two becomes larger, and then the staff can move the blocks 5 so that the left and right groups of blocks 5 are distributed on both sides of the heat shrink sleeve 2. After the movement is completed, the staff can stop pulling the blocks 5, so that the upper and lower layers of blocks 5 are engaged with the outside of the optical cable body 1. During the use of the optical cable body 1, the insertion rod 4 and the support rod 3 set between the blocks 5 can effectively prevent the heat shrink sleeve 2 from being broken by the bending force, and can effectively ensure the normal connection between the optical cable bodies 1. The above is the entire working principle of the utility model.
