Technical Field

[0001] The utility model relates to the technical field of optical cables, and specifically to a lightweight multi-core composite flexible optical cable. Background Art

[0002] A lightweight multi-core composite flexible optical cable is a special type of optical cable that combines the characteristics of multi-core optical fibers and composite flexible optical cables. A lightweight multi-core composite flexible optical cable is usually composed of multiple optical fibers combined together, and these optical fibers are encapsulated in a lightweight and flexible protective sleeve to achieve efficient data transmission and flexible applications.

[0003] In the prior art, such as a tree straightening device for landscaping proposed in the patent application number "CN202321270574.1", this communication optical cable, through the connection and action of parts such as optical fibers, an outer protective layer, a steel-plastic composite tape, a water-blocking layer, an inner protective layer, an aluminum-plastic composite tape, a cable core filler, and an outer soft protective sleeve, achieves the effect of multi-layer protection to improve the tensile and compressive properties and ensure the normal communication transmission of equipment and facilities.

[0004] However, in the above patent application, during the wiring construction, it is necessary to pull the optical cable to a specified position for wiring operations. However, when pulling, the optical cable is prone to twisting, which may cause the displacement and damage of the fiber cores inside the optical cable, affecting normal communication use. And when the outermost protective sleeve is damaged, the entire optical cable needs to be replaced, wasting resources. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lightweight multi-core composite flexible optical cable to solve the problems raised in the above background art.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A lightweight multi-core composite flexible optical cable includes a waterproof sleeve. Two protective sleeves are sleeved outside the waterproof sleeve. The inner wall of the waterproof sleeve is fixedly connected with a middle sleeve. A central fixing rod is fixedly installed at the central position inside the middle sleeve. A plurality of core sleeves are fixedly installed at the position of the outer wall of the central fixing rod inside the middle sleeve.

[0008] The fixing mechanism includes a plurality of arc-shaped fixing plates and a plurality of installation grooves. A plurality of the arc-shaped fixing plates are fixedly connected to the position of the outer wall of the central fixing rod, and a plurality of the installation grooves are opened at the position of the inner wall of the middle sleeve.

[0009] Preferably, an arc-shaped buffer plate is fixedly connected between the outer walls of the two arc-shaped fixing plates. The inner walls of the arc-shaped fixing plates are closely attached to the outer wall of the core sleeve. A fixed insertion plate is fixedly connected to the outer wall of the core sleeve. A card slot is formed in the inner wall of the arc-shaped fixing plate, and the card slot is fitted with the fixed insertion plate.

[0010] Preferably, telescopic push rods are fixedly installed on the inner walls of the several installation grooves, and buffer springs are sleeved outside the several telescopic push rods.

[0011] Preferably, one end of the telescopic push rod is fixedly connected to the arc-shaped buffer plate, and a filling body is filled between the arc-shaped buffer plate and the two arc-shaped fixing plates.

[0012] Preferably, the connecting mechanism includes a slot and a fixed shell. The slot is formed through the outer wall of the second connecting plate, and the fixed shell is fixedly installed on the outer wall of the second connecting plate.

[0015] The beneficial effects of the present utility model:

[0016] 1. In the present utility model, the two arc-shaped fixing plates in the fixing mechanism are clamped outside the core sleeve through the fixed insertion plate to limit the position between the core sleeve and the arc-shaped fixing plate. Similarly, the other groups of arc-shaped fixing plates are respectively clamped outside the other core sleeves. With the limitation of the central fixing rod and the filling body, the core sleeve and the optical fiber core installed inside it can be well fixed in the middle layer sleeve, avoiding the twisting of the multi-core composite hose fiber during the wiring construction, resulting in the displacement of the optical fiber core and affecting the normal communication use.

[0017] 2. In the present utility model, when the optical cable is impacted by an external force during wiring, the impact force acts on the sheath, causing the arc-shaped buffer plate to approach the center point of the middle layer sleeve. The telescopic push rod shortens, and the buffer spring compresses. Under the action of the elastic force of the buffer spring, the telescopic push rod elongates and returns to the initial state, thereby driving the arc-shaped buffer plate to move to the initial position, so as to buffer the external impact force well and avoid damage to the optical fiber core.

[0018] 3. In the present utility model, by moving the U-shaped plate downward, the movable block can be retracted into the insertion block, and the second connecting plate can be moved out along the outside of the insertion block through the slot, driving one of the sheaths to be removed from the waterproof sleeve, and then the other sheath can be removed from the waterproof sleeve, thus facilitating disassembly. Similarly, the other two undamaged sheaths of the other group can be installed on the waterproof sleeve through the connecting mechanism, thereby facilitating the replacement of the damaged sheath without replacing the entire optical cable, saving resources.

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] A lightweight multi-core composite flexible optical cable, as Figures 1-6 shown, includes a waterproof sleeve 2. Two sheaths 1 are sleeved outside the waterproof sleeve 2. A middle sleeve 3 is fixedly connected to the inner wall of the waterproof sleeve 2. A central fixing rod 4 is fixedly installed at the central position inside the middle sleeve 3. A plurality of core sleeves 5 are fixedly installed at the position of the outer wall of the central fixing rod 4 inside the middle sleeve 3. Optical fibers 21 are installed inside each of the plurality of core sleeves 5. A fixing mechanism is arranged between the inner wall of the middle sleeve 3 and the outer wall of the core sleeve 5. Two connecting plates II 7 are fixedly connected to both ends of one of the sheaths 1, and two connecting plates I 6 are fixedly connected to both ends of the other sheath 1. A connecting mechanism is arranged between the outer walls of the connecting plate I 6 and the connecting plate II 7. The fixing mechanism includes a plurality of arc-shaped fixing plates 8 and a plurality of installation grooves 11. The plurality of arc-shaped fixing plates 8 are all fixedly connected to the position of the outer wall of the central fixing rod 4, and the plurality of installation grooves 11 are all opened at the position of the inner wall of the middle sleeve 3.

[0030] An arc-shaped buffer plate 10 is fixedly connected between the outer walls of the two arc-shaped fixing plates 8. The inner wall of the arc-shaped fixing plate 8 is closely attached to the outer wall of the core sleeve 5. A fixing plug 9 is fixedly connected to the outer wall of the core sleeve 5. A clamping groove is opened on the inner wall of the arc-shaped fixing plate 8, and the clamping groove is fitted with the fixing plug 9. Telescopic push rods 12 are fixedly installed on the inner walls of the plurality of installation grooves 11. Buffer springs are sleeved outside the plurality of telescopic push rods 12. One end of the telescopic push rod 12 is fixedly connected to the arc-shaped buffer plate 10. A filling body 20 is filled between the arc-shaped buffer plate 10 and the two arc-shaped fixing plates 8.

[0031] Among them, the sheaths 1, the waterproof sleeve 2 and the middle sleeve 3 are all made of flexible lightweight materials, so that the optical cable has the characteristics of light weight and softness.

[0032] When in use, by clamping the two arc-shaped fixing plates 8 in the fixing mechanism on the outside of the core sleeve 5 and clamping the fixing plug plate 9 into the card slot, the position between the core sleeve 5 and the arc-shaped fixing plate 8 can be further limited. Similarly, the other groups of arc-shaped fixing plates 8 are clamped on the outside of the other core sleeves 5 respectively, and then combined with the central fixing rod 4 and the limiting position of the filling body 20, the core sleeve 5 and the fiber core 21 installed therein can be well fixed in the middle sleeve 3, avoiding the multi-core composite soft optical cable from twisting during wiring construction, causing the fiber core 21 to shift, and when multiple When the core composite soft optical cable is subjected to external impact force during wiring, the impact force acts on the sheath 1, causing the waterproof sleeve 2 and the middle sleeve 3 to be concave, and acts on the arc buffer plate 10, causing the arc buffer plate 10 to approach the center point of the middle sleeve 3, thereby shortening the telescopic push rod 12 and compressing the buffer spring. Then, under the action of the elastic force of the buffer spring, the telescopic push rod 12 extends and returns to its initial state, thereby driving the arc buffer plate 10 to move to its initial position, thereby effectively buffering the external impact force and avoiding damage to the fiber core 21.

[0033] The connecting mechanism includes a slot 14 and a fixed shell 18. The slot 14 is opened through the outer wall position of the connecting plate 2 7. The fixed shell 18 is fixedly installed at the outer wall position of the connecting plate 2 7. An insert 13 is inserted into the slot 14, and one end of the insert 13 is fixedly connected to the connecting plate 1 6. A movable block 19 is inserted into the upper surface of the insert 13, and the movable block 19 fits with the fixed shell 18. Two slide grooves 15 are opened through the outer wall of the insert 13. Slide rods 16 are fixedly installed inside the two slide grooves 15. The two slide rods 16 are externally sleeved with U-shaped plates 17, and both ends of the U-shaped plates 17 are It is fixedly connected to the movable block 19, and a support spring is provided on the outside of the two slide bars 16, and one end of the support spring is fixedly connected to the U-shaped plate 17, and the other end of the support spring is fixedly connected to the bottom end of the inner part of the slide groove 15. Through the elastic force of the support spring, the U-shaped plate 17 can always be located at the uppermost part of the slide groove 15 without being affected by external force, thereby limiting the position of the movable block 19 to be inserted into the fixed shell 18, and the position of the insertion block 13 is imagined to be in the slot 14, and then the connecting plate 1 6 is connected and fixed with the connecting plate 2 7, so that the two sheaths 1 are tightly installed and fixed on the outside of the waterproof cover 2.

[0034] Specifically, the sheath 1 is installed on the outermost layer to protect the multi-core composite flexible optical cable. When the sheath 1 is damaged, the U-shaped plate 17 can be moved downward along the two slide bars 16 installed in the two chutes 15, thereby driving the movable block 19 to move out of the fixed shell 18 and contract into the insertion block 13. The support spring is compressed. Similarly, the other group of movable blocks 19 can be contracted into the other group of fixed shells 18. At this time, the connecting plate two 7 can be moved out along the insertion block 13 through the slot 14, driving one of the sheaths 1 to move out of the waterproof sleeve 2, and then moving the other sheath 1 out of the waterproof sleeve 2, so as to conveniently complete the disassembly. Similarly, the other two undamaged sheaths 1 of the other group can be installed on the waterproof sleeve 2 through the connecting mechanism, so as to conveniently replace the damaged sheath 1 without replacing the entire multi-core composite flexible optical cable, saving resources.
