Description

Technical Field

[0001] The present application relates to the technical field of data transmission, and in particular to an optoelectronic composite cable. Background Art

[0002] In the field of communications, communication optical fiber and twisted pair data cable are both very important transmission media, and are widely used in the fields of signal transmission and information transfer technology. With the advancement of science and technology and the development of society, people's demand for the network is getting higher and higher. In practical applications, communication optical fiber will gradually replace twisted pair cables, but in the short term, twisted pair cables will still be the main ones. In order to meet the needs of users to upgrade their optical networks, it is possible to replace the original copper cable wiring system with optical fiber, which will inevitably destroy the original decoration structure for wiring. Therefore, optoelectronic composite cables came into being.

[0003] In this regard, a Chinese utility model patent with announcement number CN210865725U discloses "a fiber optic composite cable", which solves the problem of independent data cables and optical fibers needing to be constructed separately in the prior art by combining the data transmission cable and the optical fiber assembly in the first sheath layer, thereby shortening the construction period. In addition, this embodiment also solves the problem of separately setting interfaces for the data transmission cable and the optical fiber, and only needs to set an interface that combines the data transmission cable and the optical fiber, which helps to save space resources.

[0004] However, during the use of the above-mentioned optical fiber composite cable, the electromagnetic waves generated by the current transmitted in the data transmission cable are likely to interfere with the transmission signal in the optical fiber cable. In addition, the optical fiber composite cable has poor compressive and tensile strengths and is easily damaged during the construction process. Summary of the invention

[0005] The purpose of the present application is to provide an optoelectronic composite cable to solve the problem that the optoelectronic composite cable in the prior art is prone to internal crosstalk and has poor tensile strength.

[0007] In the above technical solution, the embodiment of the present application divides the cavity into five accommodating parts by adopting a large-character skeleton. A single accommodating part is used to accommodate a single data transmission cable or optical fiber component, so that the internal structure of the cable core remains stable and the tensile strength of the cable can be improved.

[0008] Furthermore, according to an embodiment of the present application, the outer sheath is made of PVC material.

[0009] Further, according to an embodiment of the present application, an insulating layer is provided between the outer sheath and the cable core.

[0013] Further, according to an embodiment of the present application, the acute angle between the first branch and the main trunk is 60°.

In addition, the terms "one", "first", "second", "third", "fourth", "fifth", "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0033] [Example 1]

[0034] Figure 1 The specific structure of an optoelectronic composite cable in this embodiment is shown. Figure 1 As shown, the optical fiber composite cable described in the present application includes an outer sheath 1, an insulating layer 2 and a cable core, and the cable core includes a data transmission cable 3, an optical fiber assembly 4 and a skeleton 5. The outer sheath 1 can be cylindrical, and a hollow cavity is formed inside it, and the cable core is arranged in the cavity. The outer sheath is made of insulating PVC material and mainly plays a protective role.

[0035] In the above technical solution, the skeleton 5 is in the shape of a large letter, with a trunk and branches distributed on both sides of the trunk. The number of branches is three, and the intersections of the three branches with the trunk are all located at the center of the trunk. The skeleton 5 divides the cavity into five accommodating parts, and a single accommodating part is used to accommodate a single data transmission cable or optical fiber component, so that the structure inside the cable core remains stable and the tensile strength of the cable can be improved. In addition, the skeleton 5 is made of high-density PE material, which has a low dielectric constant and can prevent the data transmission cable 3 and the optical fiber component 4 in the cable core from interfering with each other.

[0036] The insulating layer 2 is arranged between the outer sheath 1 and the cable core. In this embodiment, the insulating layer 2 is made of a PFT film material, the thickness of the PET film can be 0.02 mm, and is coated on the outside of the cable core to prevent the cable core from being damaged. At the same time, the cable core can also be limited to ensure that the cable core forms a circle, so that the relative position of the cable core is more certain, and the contact state between the data transmission cable 3 and the optical fiber assembly 4 inside the cable core is more stable, reducing the generation of nonlinear contact.

[0037] This application is approved by Figure 2 : represents the specific structure of the data transmission cable 3. Figure 2 As shown, the data transmission cable 3 includes a shielding layer 31 and four groups of twisted pairs. The shielding layer 31 is made of metal foil, preferably aluminum foil, and a layer of insulating material is compounded on the outside of the metal foil, and the insulating material is preferably PET. The shielding layer 31 is coated on the outside of the four groups of twisted pairs to play a shielding role, further preventing the data transmission cable 3 and the optical fiber assembly 4 from interfering with each other.

[0038] In the present application, a single twisted pair is formed by spirally twisting two conductors 33, and an inner sheath 32 is wrapped around the outer side of the conductor 33. In this embodiment, the inner sheath 32 is made of a high-density PE material, which has a low dielectric constant and can prevent the conductors 33 from interfering with each other.

[0039] This application is approved by Figure 3 : represents the specific structure of the optical fiber assembly 2. Figure 3 As shown, the optical fiber assembly includes an inner sheath 2 41 and an optical fiber 42 disposed in the inner sheath 2 41. The inner sheath 2 41 is flame-retardant polyvinyl chloride, polyethylene, cross-linked polyethylene or polyperfluoroethylene propylene.

[0040] Furthermore, the three branches of the skeleton 5 are the first branch, the second branch and the third branch, respectively. The first branch is located on one side of the trunk, and the second branch and the third branch are located on the other side of the trunk. The first branch is perpendicular to the trunk, and divides one side of the trunk into two identical accommodating parts, which are used to accommodate the optical fiber assembly 4. The other side of the trunk is divided into three accommodating parts by the second branch and the third branch (that is, the angle between the second branch and the third branch is 60°), and these three accommodating parts are used to accommodate the data transmission cable 3. In this way, a structure with two optical fiber assemblies 4 and three data transmission cables 3 is formed.

[0041] [Example 2]

[0042] Figure 4 The specific structure of an optoelectronic composite cable in this embodiment is shown. Figure 4 As shown, the difference between this embodiment and embodiment 1 is that: the first branch of the skeleton 5 is perpendicular to the main trunk, dividing one side of the main trunk into two identical accommodating parts, which are used to accommodate the optical fiber assembly 4, and the other side of the main trunk is divided into three accommodating parts by the second branch and the third branch, and the angle between the second branch and the third branch is 90°, and the accommodating part between the second branch and the third branch is also used to accommodate the optical fiber assembly 4, and the remaining two accommodating parts are used to accommodate the data transmission cable 3. In this way, a structure with three optical fiber assemblies 4 and two data transmission cables 3 is formed.

[0043] The other components and functions of this embodiment are consistent with those of Embodiment 1 and will not be described in detail here.

[0044] [Example 3]

[0045] Figure 5 The specific structure of an optoelectronic composite cable in this embodiment is shown. Figure 5As shown, the difference between this embodiment and embodiment 1 is that the first branch divides one side of the trunk into two accommodating parts, one large and one small. The accommodating parts are fan-shaped spaces, the angle of the large accommodating part is 120°, and the angle of the small accommodating part is 60°. The large accommodating part is used to accommodate the optical fiber assembly 4, and the small accommodating part is used to accommodate the data transmission cable 3. The other side of the trunk is divided into three accommodating parts by the second branch and the third branch, and these three accommodating parts are used to accommodate the data transmission cables 3. In this way, a structure with one optical fiber assembly 4 and four data transmission cables 3 is formed.

[0046] The other components and functions of this embodiment are consistent with those of Embodiment 1 and will not be described in detail here.

[0047] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods.
