Description

Technical Field

[0001] This utility model relates to the field of optical cable technology, and in particular to a concealed butterfly-shaped optical cable patch cord. Background Technology

[0002] A Chinese patent with publication number CN201207091Y discloses an optical fiber connector that is installed on an optical cable whose outer sheath covers the optical fiber. The connector has a ferrule that holds the optical fiber exposed at the front end of the optical cable, and an optical cable fixing component that is connected to the ferrule in a relatively movable state to fix the outer sheath of the optical cable.

[0003] However, the aforementioned fiber optic connectors have the following drawbacks: their outer wall is usually fitted with a protective tube to protect the fiber optic cable from damage. In order to facilitate faster installation of the fiber optic cable into the home, the head end of the cable is usually extended out of the protective tube, and the fiber optic connector is pre-installed on the head end of the cable. However, during transportation, the aforementioned fiber optic connector may cause the cable to shake or even bend, resulting in accidental breakage of the fiber optic cable. In addition, the protective tubes on the market are usually black tubes, and the exposed black protective tubes are not aesthetically pleasing after the fiber optic cable is installed indoors, which urgently needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a concealed butterfly-shaped optical cable patch cord, which enables concealed installation of optical cables and effectively prevents optical cables from breaking during transportation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a concealed butterfly-shaped optical cable patch cord, comprising an optical cable assembly and an optical fiber connector. The optical cable assembly includes a protective tube and a transparent optical fiber body disposed within the protective tube. The optical fiber connector is used to connect the optical fiber body. The optical fiber connector includes a tail sleeve fixed at its tail and used to connect the optical fiber body. The portion of the end of the optical fiber body extending out of the protective tube forms a transparent exposed section. An elastic protective element for protecting the transparent exposed section is detachably provided between the protective tube and the tail sleeve. The elastic protective element is formed by coiling a spiral body with elastic deformation capability. The elastic protective element has an inward elastic contraction force. When the elastic protective element is sleeved on the outside of the optical fiber body between the protective tube and the tail sleeve, both ends of the elastic protective element contact and are positioned with the outer walls of the corresponding protective tube and tail sleeve, respectively.

[0006] By adopting the above technical solution, the elastic protective component is stretched outward and fitted onto the outside of the transparent exposed section, positioned between the tail sleeve and the protective tube. At this time, both ends of the elastic protective component are respectively attached and positioned to the outer walls of the protective tube and the tail sleeve through static friction. Thus, during transportation, the transparent exposed section will not bend due to the protection of the elastic protective component. In addition, the elastic protective component also plays a buffering and shock-absorbing role for the transparent exposed section during transportation, which can effectively prevent the optical fiber body of the transparent exposed section from losing light. When this utility model needs to be installed in the market, the protective tube can be peeled off from the optical fiber body. Utilizing the transparent characteristics of the optical fiber body, even if the optical fiber body is exposed in a conspicuous place indoors, the transparent optical fiber body can blend into the surrounding environment, achieving the purpose of concealed installation of the optical fiber body. This improves the aesthetics of the optical cable after installation and has the effect of achieving concealed installation of optical cable and effectively preventing optical cable from losing light during transportation.

[0007] A further feature of this invention is that the protective tube includes a wrapping layer surrounding the optical fiber body and tear-off portions symmetrically arranged on both sides of the wrapping layer, wherein the tear-off portions on both sides extend along the length direction of the optical fiber body.

[0008] By adopting the above technical solution, the operator can tear the protective tube in half from the middle of the package by relatively opening the tear section, thereby exposing the optical fiber body.

[0009] A further feature of this invention is that the tearing section is provided with tearing ribs, which are disposed within the tearing section along the length direction of the optical fiber body.

[0010] By adopting the above technical solution, the addition of tear-resistant ribs can improve the structural strength of the tear-resistant parts on both sides, thereby preventing the tear-resistant parts from breaking during the relative tearing process.

[0011] A further feature of this invention is that the thickness of the tearing portion is greater than the thickness of the wrapping layer.

[0012] By adopting the above technical solution, the cladding layer can be successfully peeled off from the optical fiber body when the two tearing sections tear relative to each other.

[0013] A further feature of this invention is that the outer wall of the tail sleeve is treated with a frosted surface.

[0014] By adopting the above technical solution, the outer wall of the tail sleeve treated with sandblasting has higher friction, which can effectively improve the frictional positioning force between the outer wall of the tail sleeve and the elastic protective component.

[0015] A further feature of this invention is that the elastic protective element is made of transparent silicone.

[0016] By adopting the above technical solution, the good elasticity and restoring ability of silicone itself can be utilized to enable the two ends of the elastic protective component to be better clamped and positioned with the corresponding protective tube and the outer wall of the tail sleeve.

[0017] A further feature of this invention is that the outer wall of the wrapping layer has a tearing groove along the length of the optical fiber body.

[0018] By adopting the above technical solution, the opening of the tear groove makes the wrapping layer easier to tear, thereby achieving the purpose of quickly peeling off the protective tube.

[0019] A further feature of this invention is that the elastic protective member is provided with an elastic reset spiral rib, which is arranged along the spiral direction of the elastic protective member.

[0020] By adopting the above technical solution, the addition of the elastic reset spiral rib can increase the tightening force of the elastic protective component when it contracts inward, thereby enabling the elastic protective component to retract faster and allowing the two ends of the elastic protective component to achieve high-stress clamping and positioning with the outer wall of the corresponding protective tube and tail sleeve.

[0021] A further feature of this invention is that a friction sleeve is provided on the outer fixed sleeve of the tail sleeve, and the end of the elastic protective member near the tail sleeve is positioned by friction with the friction sleeve.

[0022] By adopting the above technical solution, the addition of the friction sleeve can increase the static friction between the elastic protective component and the friction sleeve outside the tail sleeve, thereby effectively preventing the fixed protective component from falling off the tail sleeve during transportation.

[0023] A further feature of this invention is that the outer wall of the tail sleeve is provided with a positioning block, which extends into the spiral gap of the elastic protective member and engages with it to prevent detachment.

[0024] By adopting the above technical solution, when one end of the elastic protective component is clamped and positioned on the tail sleeve, the positioning block will extend into the spiral gap of the elastic protective component, thereby effectively preventing the elastic protective component from slipping off the end of the tail sleeve.

[0025] In summary, this utility model has the following beneficial effects:

[0026] An elastic protective element is installed outside the optical fiber body extending from the protective tube. This element is composed of a spiral body with elastic deformation capabilities and possesses an inward elastic contraction force. When the elastic protective element is fitted over the optical fiber body between the protective tube and the tail sleeve, its two ends contact and are positioned against the outer walls of the corresponding protective tube and tail sleeve. Utilizing its own elastic force, the element is pushed outwards and fitted over the transparent exposed section, positioned between the tail sleeve and the protective tube. At this point, its two ends are fixed to the outer walls of the protective tube and tail sleeve through static friction. Thus, during transportation, the transparent exposed section is protected by this elastic force. The protective sleeve prevents bending, and the elastic protective sleeve also cushions and reduces shock during transportation, effectively preventing the optical fiber body from losing light. When the present invention is to be installed in the market, the protective sleeve can be peeled off from the optical fiber body. Utilizing the transparent nature of the optical fiber body, even if the optical fiber body is exposed in a conspicuous place indoors, the transparent optical fiber body can blend into the surrounding environment, achieving the purpose of concealed installation of the optical fiber body. This improves the aesthetics of the optical cable after installation and has the effect of achieving concealed installation of optical cable and effectively preventing the optical cable from losing light during transportation.

[0034] The present invention will be further described below with reference to the accompanying drawings. Specific Implementation Example 1

[0036] A concealed butterfly-shaped fiber optic patch cord, such as Figure 1-3 As shown, the optical cable assembly includes an optical cable assembly 1 and an optical fiber connector 2. The optical cable assembly 1 includes a protective tube 11 and a transparent optical fiber body 12 disposed within the protective tube 11. The optical fiber body 12 is composed of a fiber core 121 and a concentric glass body 122 surrounding the fiber core 121. The optical fiber connector 2 is used to connect the optical fiber body 12. The optical fiber connector 2 includes a tail sleeve 21 fixed at its tail and used to connect the optical fiber body 12. The portion of the end of the optical fiber body 12 extending out of the protective tube 11 forms a transparent exposed section 120. An elastic protective element 3 for protecting the transparent exposed section 120 is detachably provided between the protective tube 11 and the tail sleeve 21. The elastic protective element 3 is composed of a spiral core with elastic deformation capability. The body is coiled, and the elastic protective element 3 has an inward elastic contraction force. When the elastic protective element 3 is sleeved on the outer side of the optical fiber body 12 between the protective tube 11 and the tail sleeve 21, the two ends of the elastic protective element 3 contact and position with the outer walls of the corresponding protective tube 11 and tail sleeve 21 respectively. The outer wall of the tail sleeve 21 is surface frosted. The frosted outer wall of the tail sleeve 21 has higher friction, which can effectively improve the frictional positioning force between the outer wall of the tail sleeve 21 and the elastic protective element 3. The material of the elastic protective element 3 is transparent silicone. By utilizing the good elastic restoring ability of silicone itself, the two ends of the elastic protective element 3 can be better clamped and positioned with the outer walls of the corresponding protective tube 11 and tail sleeve 21.

[0037] like Figure 2-3 As shown, the protective tube 11 includes a wrapping layer 111 surrounding the optical fiber body 12, and tear-off portions 112 symmetrically arranged on both sides of the wrapping layer 111. The tear-off portions 112 extend along the length of the optical fiber body 12. By tearing the tear-off portions 112 relative to each other, the operator can tear the protective tube 11 in half from the middle of the wrapping layer, thereby exposing the optical fiber body 12. The tear-off portions 112 are provided with tear-off ribs 1121, which are arranged along the length of the optical fiber body 12. The addition of tear-off ribs 1121 can improve the structural strength of the tear-off portions 112 on both sides, thereby preventing the tear-off portions 112 from breaking during the relative tearing process. The thickness of the tear-off portions 112 is greater than the thickness of the wrapping layer 111, so that the wrapping layer 111 can be easily peeled off from the optical fiber body 12 when the tear-off portions 112 on both sides are torn relative to each other.

[0038] The basic working principle of this utility model is as follows: An elastic protective element 3 is fitted over the optical fiber body 12 extending from the protective tube 11. The elastic protective element 3 is formed by a spiral body with elastic deformation capability and has an inward elastic contraction force. When the elastic protective element 3 is fitted over the optical fiber body 12 between the protective tube 11 and the tail sleeve 21, the two ends of the elastic protective element 3 are respectively in contact with and positioned against the outer walls of the corresponding protective tube 11 and tail sleeve 21. Utilizing the elastic force of the elastic protective element 3 itself, the elastic protective element 3 is pushed outward and fitted over the transparent exposed section 120 and positioned between the tail sleeve 21 and the protective tube 11. At this time, the two ends of the elastic protective element 3 are respectively attached and positioned against the outer walls of the protective tube 11 and tail sleeve 21 by static friction. Thus, during transportation, the transparent exposed section 120... The exposed section 120 will not bend due to the protection of the elastic protective element 3. In addition, the elastic protective element 3 also acts as a buffer and shock absorber for the transparent exposed section 120 during transportation, which can effectively prevent the optical fiber body 12 of the transparent exposed section 120 from losing light. When this utility model needs to be installed in the market, the protective tube 11 can be peeled off from the optical fiber body 12. Utilizing the transparent characteristics of the optical fiber body 12, even if the optical fiber body 12 is exposed in a conspicuous place indoors, the transparent optical fiber body 12 can blend into the surrounding environment, achieving the purpose of concealed installation of the optical fiber body 12. This improves the aesthetics of the optical cable after installation and has the effect of achieving concealed installation of optical cable and effectively preventing optical cable from losing light during transportation. Specific Implementation Example 2

[0040] A concealed butterfly-shaped fiber optic patch cord, such as Figure 4-6As shown, a tearing groove 1111 is formed on the outer wall of the wrapping layer 111 along the length of the optical fiber body 12. The tearing groove 1111 makes the wrapping layer 111 easier to tear, thereby achieving the purpose of quickly peeling off the protective tube 11. The elastic protective member 3 is provided with an elastic reset spiral rib 31. The elastic reset spiral rib 31 is arranged along the spiral direction of the elastic protective member 3. The addition of the elastic reset spiral rib 31 can increase the tightening force of the elastic protective member 3 when it contracts inward, so that the elastic protective member 3 can retract more quickly, and the two ends of the elastic protective member 3 can achieve high-stress clamping and positioning with the outer wall of the corresponding protective tube 11 and tail sleeve 21. The tail sleeve 21 is fixed outside. A friction sleeve 22 is provided, and the end of the elastic protective member 3 near the tail sleeve 21 is positioned by friction with the friction sleeve 22. The addition of the friction sleeve 22 can increase the static friction between the elastic protective member 3 and the friction sleeve 22 outside the tail sleeve 21, thereby effectively preventing the protective member from falling off the tail sleeve 21 during transportation. A positioning block 211 is provided on the outer wall of the tail sleeve 21. The positioning block 211 extends into the spiral gap 32 of the elastic protective member 3 and cooperates with it to prevent it from falling off. When one end of the elastic protective member 3 is clamped and positioned on the tail sleeve 21, the positioning block 211 will extend into the spiral gap 32 of the elastic protective member 3, thereby effectively preventing the elastic protective member 3 from slipping off the end of the tail sleeve 21.

[0041] The other structures in this embodiment are the same as those in Specific Embodiment 1, and will not be described again here.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
