Description

Technical Field

[0001] The utility model relates to the technical field of communication cables, and particularly relates to a two-core indoor data cable with a sheath. Background Art

[0002] Indoor data cables refer to cables specifically designed for data transmission within buildings. They are commonly used to build local area networks (LANs) and connect various devices such as computers, printers, servers, routers, etc. for resource sharing, high-speed data exchange, and communication.

[0003] Indoor data cables can be divided into two categories: copper cables and optical fibers.

[0004] Searching the patent number: CN204407063U, we know a data cable, which includes a positioning frame, a twisted full-color spectrum wire pair, and a protective sleeve. Its characteristics are that the positioning frame is an elastomer in the middle of the cable core, the four sides of the elastomer positioning frame are in an equal arc shape, reinforcing fibers are arranged inside the positioning frame, and the central lines of the equal arcs of adjacent sides on the positioning frame are perpendicular to each other.

[0005] Through the above literature, although CN204407063U optimizes the deficiencies of existing data cables, considering the actual performance of data cables during indoor operations, it is found that there are still the following deficiencies. The existing data cables generally adopt a direct plug-in connection. When there is an obstruction at the plug-in end of the cable, personnel need to split and branch the cable, and the operation process is relatively cumbersome and inconvenient. At the same time, the protection performance at the docking part of the existing cable is relatively low. Although there are protective covers at some docking parts, there are no locking components, resulting in easy detachment from the protection of the docking position.

[0006] Therefore, this application proposes a two-core indoor data cable with a sheath. Content of the Utility Model

[0027] Embodiment 1

[0028] In order to solve the technical problems in the background art, the following is a double-core indoor data cable with a sheath:

[0029] Combined with Figures 1-5 As shown, a double-core indoor data cable with a sheath provided by the present utility model includes a first sheath body 1, a protective housing 4 and a second sheath body 9. A docking assembly 3 is docked and installed at the end of the first sheath body 1. An inner cavity body 5 is arranged inside the protective housing 4. A built-in connection assembly 6 is docked and installed inside the inner cavity body 5. The second sheath body 9 penetrates through the protective housing 4 and is installed and connected to the built-in connection assembly 6. Cable assemblies 2 are sleeved inside both the first sheath body 1 and the second sheath body 9. The cable assemblies 2 are respectively installed and connected to the docking assembly 3 and the built-in connection assembly 6. An overload component 8 is fixedly installed outside the inner cavity body 5. Docking heads 7 are respectively clamped at the top and bottom of the overload component 8, and the docking heads 7 are clamped and connected to the overload component 8 through clamping blocks 71. The inner ends of the docking heads 7 are installed and connected to the built-in connection assembly 6, and the outer ends are in docking cooperation with the docking assembly 3;

[0030] During this period, through the docking between the docking component 3 and the docking head 7, the electrical connection between the cables is realized. By adding a sheath body on the basis of the cable component 2, the sheathing protection of the cable component 2 is achieved, and the working strength of the cable itself is further improved, and the tensile strength and flexibility of the cable are enhanced. Through the built-in connection component 6 and the receiving part, the mutual connection between two groups of cables is realized. Through the docking head 7 and the overload component 8, the cables can be docked with each other, and the docking head 7 and the overload component 8 can be separated according to the actual docking requirements. In this way, the plug-in end of the cable can be separated from the wire end, realizing fast branch docking. Through the mutual cooperation between the docking component 3 and the protective cover shell 4, the real-time protection of the cable docking part is realized, ensuring the stability of the docking part. And an elastic clamping structure is adopted between the two, which can not only ensure the stability of the protective cover shell 4 after docking, but also facilitate quick disassembly by personnel.

[0031] The docking component 3 includes a docking cap 31, a first docking seat 32, and a docking part 33. The end of the first sheath body 1 is docked and installed with the docking cap 31. The docking cap 31 is fixedly installed with the first docking seat 32. Inside the first docking seat 32, a cable connector 321 electrically connected to the cable component 2 is docked and installed. Docking parts 33 are docked and installed on both the top and bottom of the first docking seat 32; The overload component 8 includes a carrier plate 81, a sliding part 82, and a clamping seat 83. The carrier plate 81 is fixedly installed on the front side of the inner cavity body 5. Clamping seats 83 are fixedly installed on both the top and bottom of the carrier plate 81. The docking head 7 is clamped in the clamping seat 83 through a clamping block 71. A sliding part 82 slidably connected to the protective cover shell 4 is arranged on the carrier plate 81;

[0032] During this period, the docking with the end face of the protective cover shell 4 is realized through the docking cap 31. After docking, the docking part 33 on the first docking seat 32 completes the clamping with the protective cover shell 4, and personnel can realize its sliding operation outside the inner cavity body 5 by pushing the protective cover shell 4. When docking, the protective cover body 4 completes the complete protection of the inner cavity body 5. When separating, the inner cavity body 5 can protrude from the protective cover body 4. And if the plug-in end of the cable needs to be branched, the docking head 7 can be separated from the clamping seat 83 through the clamping block 71. When the protective cover shell 4 is pushed, the protective cover shell 4, the sliding part 82 and the carrier plate 81 perform sliding cooperation.

[0033] Embodiment 2

[0034] As Figure 1 and Figure 5 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0035] In this embodiment, the cable assembly 2 includes an inner sleeve 21, an aramid strengthening member 22, a core coating layer 23, and a core body 24. Two sets of inner sleeves 21 are sleeved inside the first sheath body 1 and the second sheath body 9. Aramid strengthening members 22 are sleeved inside the inner sleeves 21. A core coating layer 23 is sleeved inside the aramid strengthening member 22. A core body 24 is sleeved inside the core coating layer 23. The core bodies 24 inside the first sheath body 1 and the second sheath body 9 are respectively installed and connected to the cable joint 321 and the built-in connection assembly 6.

[0036] The combined sleeving of the core body 24 is completed through the inner sleeve 21, the aramid strengthening member 22, and the core coating layer 23, effectively ensuring the stability and reliability of the core body 24 during preparation and operation. The flat-shaped overall sheath structure design can be separated into independent single-core indoor optical cables, facilitating branching.

[0037] In this embodiment, the cable assembly 2 further includes a connecting member 25. Connecting members 25 that are connected to each other are fixedly installed between the inner sleeves 21, and a fiber paste filling layer 11 is filled between the connecting member 25 and the first sheath body 1.

[0038] The mutual connection between the two sets of inner sleeves 21 is realized through the connecting member 25, forming a flat-shaped overall sheath structure. And the fiber paste filling layer 11 can prevent the intrusion of moisture in the air and alleviate the influence of external mechanical forces such as vibration, impact, and bending on the optical fiber.

[0039] Embodiment Three

[0040] As Figures 1-5 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0041] In this embodiment, the docking component 33 includes a guiding and positioning member 331 and a spring member 332. Installation ports 322 are provided at both the top and bottom of the first docking seat 32. A spring member 332 is docked and installed inside the installation port 322, and an end of the spring member 332 is docked and installed with a guiding and positioning member 331 that extends out of the installation port 322.

[0042] During this period, when the protective housing 4 is docked with the first docking seat 32, the top of the guiding and positioning member 331 will be squeezed by the protective housing 4, causing the guiding and positioning member 331 to press downward and retract inward. At this time, the spring member 332 enters the compressed state until the protective housing 4 completes the full docking with the first docking seat 32.

[0043] In this embodiment, guiding ports 51 are provided at both the top and bottom of the inner cavity body 5. A limiting guide plate 42 that is in butt joint and cooperation with the guiding port 51 is fixedly installed on the inner wall of the protective housing 4. The limiting guide plate 42 penetrates through the inner cavity body 5 and limits the clamping block 71.

[0044] During the period when the protective cover 4 can be docked, the protective cover 4 will drive the limit guide plate 42 on the inner wall to be guided along the guide port 51. After the protective cover 4 is docked, the end of the limit guide plate 42 will be inserted into the clamping seat 83, and the effect is that it can press the clamping block 71 in the clamping seat 83 to ensure the firmness of the clamping block 71 after clamping and prevent the clamping block 71 from disengaging from the clamping seat 83.

[0045] In this embodiment, the built-in connection component 6 includes a second docking seat 61 and a built-in fiber wire 62. The second docking seat 61 is installed and docked inside the inner cavity body 5, and the second docking seat 61 is installed and connected to the cable assembly 2 in the second sheath body 9. A built-in fiber wire 62 connected to the docking head 7 is installed and docked on the second docking seat 61.

[0046] During this period, the second docking seat 61 and the built-in fiber wire 62 are built inside the inner cavity body 5, and the second docking seat 61 realizes the connection between the built-in fiber wire 62 and the cable assembly 2 in the second sheath body 9.

[0047] When the docking head 7 needs to be branched and docked, the operator can disengage the docking head 7 from the clamping seat 83 and pull the docking head 7. The built-in fiber wire 62 inside the inner cavity body 5 will extend outward accordingly to cooperate with the docking operation.

[0048] In this embodiment, positioning holes 41 are provided at both the top and bottom of the protective cover 4, and the positioning holes 41 are engaged and matched with the guiding and positioning members 331.

[0049] By combining the above content, when the protective cover 4 is docked with the first docking seat 32, the top of the guiding and positioning member 331 will be squeezed by the protective cover 4, causing the guiding and positioning member 331 to press downward and retract inward. At this time, the spring member 332 enters the compressed state until the positioning hole 41 on the protective cover 4 is completely docked with the first docking seat 32.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
