Description

Technical Field

[0001] The invention belongs to the technical field of optical cables, in particular to a ribbon optical cable. Background Art

[0002] Ribbon 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.

[0003] When laying optical cables, they are not only set up in areas with human activities such as cities and villages, but also in sparsely populated areas when necessary, such as some grasslands, mountains and some river areas. When laying in mountains, they are generally laid along the surface of the mountain. For mountains with exposed sharp rocks, when the optical cable is attached to the protruding rock surface, it bends and attaches itself. Under the impact of external wind, the optical cable swings and rubs against the rock. After a long period of friction, the protective insulation layer on the surface of the optical cable is cut by the side edges of the rock corners. Laying optical cables on the surface of mountains is more difficult than on plains. If the insulation layer on the surface of the optical cable is worn and damaged by the rock, maintenance is also more troublesome.

[0004] To this end, the present invention provides a ribbon optical cable with a protective sleeve. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] A plurality of concave points are provided on one side of the bayonet; the fixing pin rotates and passes through the protective sleeve, and a plurality of convex points are provided on the inner wall of the outer end of the fixing pin, and the convex points are embedded in the concave points; the bayonet is buckled on the fixing pin, and then the fixing pin is rotated so that the convex points on the fixing pin are embedded in the concave points one by one, and at this time, the connecting plate and the fixing pin are fixed to prevent the connecting plate from separating from the fixing pin by itself, causing the protective sleeve to separate from the main body.

[0008] The inner end surface of the fixing pin is provided with a bonding plate, the fixing pin is fixedly connected to the bonding plate, the bonding plate is in an arc shape, the interior of the fixing pin is hollow, and a pin and a chemical coagulant package are provided in the hollow portion, one end of the pin is placed in the "I" groove at the outer end of the fixing pin, and the other end of the pin is close to the chemical coagulant package, and the hollow portion is connected to a through hole opened on the bonding plate; when the fixing pin is rotated, the flat-blade screwdriver squeezes the pin, and the pin breaks the chemical coagulant package, and the chemical coagulant penetrates along the through hole between the bonding plate and the main body, further fixing the fixing pin, and at the same time, the bonding plate rotates with the fixing pin, and the arc surface is tightly attached to the surface of the main body, further stabilizing the protective sleeve and the main body.

[0009] The inner concave surface of the bonding plate is provided with a plurality of spikes, which are in a cone shape and have a length less than the thickness of the outer insulating layer of the main body; the spikes rotate together with the bonding plate and scrape dents on the outer surface of the main body, so that the chemical coagulant penetrates into the dents, thereby increasing the bonding strength between the bonding plate and the main body, and further increasing the connection strength between the main body and the protective sleeve, thereby preventing relative displacement between the protective sleeve and the main body, which would affect the buffering protection of the protective sleeve on the main body.

[0010] The interior of the protective sleeve is hollow, and a pouring hole is provided on the outer ring of the protective sleeve, and the pouring hole is connected to the hollow shape of the protective sleeve; a foaming agent is poured into the hollow part inside the protective sleeve through the pouring hole, and the foaming agent supports the hollow part, so that the protective sleeve expands and becomes larger, and different amounts of foaming agent are injected according to the surface shape of the side ridges at the corners of the mountain, the size of the depressions or the size of the stone cracks, so that the protective sleeve can be stably placed at the side ridge position, or stably embedded in the stone seal, thereby improving the wind resistance of the main body and reducing the destructive wear of the surface of the main body by the mountain stones when the main body swings.

[0011] A plurality of partitions are arranged in the hollow shape of the protective sleeve, and the partitions divide the hollow shape of the protective sleeve into a plurality of pouring cavities, and each pouring cavity corresponds to a pouring hole; by setting the partitions, the hollow part is isolated into a plurality of pouring cavities, that is, the foaming agent is poured according to the position point where the side ridge of the mountain scrapes on the protective sleeve, so as to accurately protect the protective sleeve and the main body and reduce unnecessary foaming agent pouring.

[0012] A protrusion is provided on the inner ring surface of the protective sleeve, the thickness of the connection part between the protrusion and the protective sleeve is less than the thickness of the protective sleeve, and an overflow hole is opened on the protrusion, and the overflow hole is connected to the casting cavity; the foaming agent expands and squeezes the protrusion, and the protrusion is squeezed on the main body. At the same time, the foaming agent penetrates from the overflow hole into the gap between the protective sleeve and the main body, and the stability between the main body and the protective sleeve is further enhanced. The foaming agent expands from the overflow hole from the inside to the outside of the protective sleeve, the foaming agent penetration effect is better, the fit between the main body and the protective sleeve is tighter, and the stability is stronger.

[0013] The protective sleeve is provided with limit plates at both ends, the limit plates are half-wrapped on the main body, the plate surface of the limit plate is provided with multiple limit rods, the end surface of the limit plate is provided with a fixing rod, and the fixing rod penetrates into the casting cavity; after the main body is bent, the limit plate approaches the mountain with the main body, so that the limit plate is attached to the two sides of the side ridge, and because the limit plate is provided with a fixing rod, the fixing rod connects the limit plate and the protective sleeve together, limits the displacement between the protective sleeve and the main body, so that the protective sleeve is stably placed on the stone side ridge, and at the same time, the end of the limit rod is in contact with the gap on the side wall of the mountain, thereby enhancing the grip of the limit plate on the side wall of the mountain, and the limit plate is half-wrapped on the main body, which makes it convenient for the limit plate to be put on the main body, and there is no need to put it on the main body from one end of the main body.

[0014] The outer ring of the fixing rod is provided with multiple circles of barbs, the barbs penetrate the partition, and the thickness of the partition penetrated by the barbs is thickened; the barbs are used to prevent the fixing rod from detaching from the partition after penetrating the partition, and the barbs are used to increase the contact surface between the fixing rod and the foaming agent, thereby enhancing the connection strength between the fixing plate and the protective sleeve.

[0015] Each of the limit rods is threadedly connected to the limit plate; the limit rod thread passes through the limit plate, and one or more limit rods are rotated so that the end of the limit rod effectively contacts the stone gap, ensuring that the end of the limit rod effectively contacts the gap, which is more applicable.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The main body is attached to the side edge of the mountain corner, and the protective sleeve is put on. Then the bayonet of the connecting plate is buckled on the fixing pin, so that the protective sleeve is tightly wrapped on the main body and bends synchronously with the main body to protect the outer insulation layer of the main body, preventing the side edge of the mountain corner from cutting and scratching the outer insulation layer of the main body; the protective sleeve is a disconnect type, which is convenient and quick to protect the protective sleeve at any position on the main body.

[0018] 2. When rotating the fixing pin, the flat-blade screwdriver squeezes the pin, and the pin breaks the chemical coagulant bag. The chemical coagulant penetrates into the space between the bonding plate and the main body along the through hole, further fixing the fixing pin. At the same time, the bonding plate rotates with the fixing pin, and the arc surface is closely attached to the surface of the main body, further stabilizing the protective sleeve and the main body.

[0019] 3. Pour foaming agent into the hollow part of the protective casing through the pouring hole.

[0040] The protective sleeve 2 is provided with a limit plate 18 at both ends, and the limit plate 18 is half wrapped on the main body 1. The plate surface of the limit plate 18 is provided with a plurality of limit rods 19, and the end face of the limit plate 18 is provided with a fixing rod 20, and the fixing rod 20 penetrates into the casting cavity 15; after the main body 1 is bent, the limit plate 18 approaches the mountain with the main body 1, so that the limit plate 18 is attached to the two sides of the side ridge, and because the limit plate 18 is provided with a fixing rod 20, the fixing rod 20 connects the limit plate 18 and the protective sleeve 2 together, and limits the displacement between the protective sleeve 2 and the main body 1, so that the protective sleeve 2 is stably placed on the stone side ridge, and at the same time, the end of the limit rod 19 abuts against the gap on the side wall of the mountain, thereby enhancing the grip of the limit plate 18 on the side wall of the mountain, and the limit plate 18 is half wrapped on the main body 1, which is convenient for the limit plate 18 to be sleeved on the main body 1, and there is no need to sleeve the main body 1 from one end of the main body 1.

[0042] Embodiment 2:

[0043] Comparative Example 1 is another implementation mode of the present invention, wherein each of the limit rods 19 is threadedly connected to the limit plate 18; the limit rod 19 thread passes through the limit plate 18, and one or more limit rods 19 are rotated so that the end of the limit rod 19 effectively contacts the stone gap, ensuring that the end of the limit rod 19 effectively contacts the gap, and the applicability is stronger.

[0044] Working principle: The main body 1 is attached to the side edge of the mountain corner, and the protective sleeve 2 is put on. Then the bayonet 5 of the connecting plate 3 is buckled on the fixing pin 4, so that the protective sleeve 2 is tightly wrapped on the main body 1 and bends synchronously with the main body 1 to protect the outer insulation layer of the main body 1 and prevent the mountain corner edge from cutting and scratching the outer insulation layer of the main body 1; the protective sleeve 2 is a disconnect type, which is convenient for the protective sleeve 2 to protect any position on the main body 1, which is convenient and quick;

[0045] The bayonet 5 is buckled on the fixing pin 4, and then the fixing pin 4 is rotated so that the protrusions 7 on the fixing pin 4 are embedded in the concave points 6 one by one, and the connection plate 3 and the fixing pin 4 are fixed at this time to prevent the connection plate 3 from being separated from the fixing pin 4 by itself, causing the protective sleeve 2 to be separated from the body 1;

[0046] When the fixing pin 4 is rotated, the flat screwdriver squeezes the pin 9, and the pin 9 breaks the chemical coagulant bag 10, and the chemical coagulant penetrates into the gap between the bonding plate 8 and the body 1 along the through hole 11, further fixing the fixing pin 4. At the same time, the bonding plate 8 rotates with the fixing pin 4, and the arc surface is closely attached to the surface of the body 1, further stabilizing the protective sleeve 2 and the body 1;

[0047] The spurs 12 rotate together with the laminating plate 8 and scrape out indentations on the outer surface of the body 1, so that the chemical coagulant penetrates into the indentations, thereby increasing the bonding strength between the laminating plate 8 and the body 1, and further increasing the connection strength between the body 1 and the protective sleeve 2, thereby preventing the protective sleeve 2 from relative displacement with the body 1, thereby affecting the buffering protection of the protective sleeve 2 on the body 1;

[0048] A foaming agent is poured into the hollow part of the protective sleeve 2 through the pouring hole 13. The foaming agent supports the hollow part, so that the protective sleeve 2 expands and becomes larger. Different amounts of foaming agent are injected according to the surface shape of the side ridges at the corners of the mountain, the size of the depressions or the stone gaps, so that the protective sleeve 2 is stably placed at the side ridge position point, or stably embedded in the stone seal, thereby improving the wind resistance of the main body 1 and reducing the destructive wear of the mountain stones on the surface of the main body 1 when the main body 1 swings;

[0049] By setting the partition 14, the hollow part is separated into a plurality of pouring cavities 15, that is, the foaming agent is poured according to the position where the side edge of the mountain scrapes on the protective sleeve 2, so as to accurately protect the protective sleeve 2 and the body 1 and reduce unnecessary foaming agent pouring;

[0050] The foaming agent expands and squeezes the protrusion 16, and the protrusion 16 is squeezed on the body 1.

In addition, the foaming agent expands from the overflow hole 17 from the inside to the outside of the protective sleeve 2, and the foaming agent penetration effect is better, and the body 1 and the protective sleeve 2 are more closely fitted and more stable.

[0051] After the body 1 is bent, the limit plate 18 moves closer to the mountain with the body 1, so that the limit plate 18 is attached to both sides of the side ridges. Because the limit plate 18 is provided with a fixing rod 20, the fixing rod 20 connects the limit plate 18 and the protective sleeve 2 together, and limits the displacement between the protective sleeve 2 and the body 1, so that the protective sleeve 2 is stably placed on the stone side ridges. At the same time, the end of the limit rod 19 abuts against the gap on the side wall of the mountain, thereby enhancing the grip of the limit plate 18 on the side wall of the mountain. The limit plate 18 is half-wrapped on the body 1, which makes it convenient for the limit plate 18 to be sleeved on the body 1, and it is not necessary to sleeve the body 1 from one end of the body 1.
