[0060] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0061] like Figure 1 and Figure 2 As shown, this embodiment provides a flat optoelectronic composite cable 100, including an optical unit 10, an electrical unit 20, an outer sheath 30, and a support member 40. A cavity 301 is provided in the outer sheath 30, and the optical unit 10, the electrical unit 20, and the support member 40 are all provided in the cavity 301, and the outer sheath 30 protects the optical unit 10 and the electrical unit 20.

[0062] For the convenience of subsequent reading, the present application introduces a first direction X, a second direction Z, and a third direction Y to describe the embodiments of the present application. The first direction X, the second direction Z, and the third direction Y may be three non-parallel linear directions in space; further, the first direction X, the second direction Z, and the third direction Y may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0063] The extension direction of the flat optoelectronic composite cable 100 is parallel to the third direction Y, and the extension directions of the optical unit 10 , the electrical unit 20 , the outer sheath 30 , and the support member 40 are also parallel to the third direction Y. Along the third direction Y, the cavity 301 extends from one end of the outer sheath 30 to the other end penetrating the outer sheath 30 .

[0064] The support member 40 includes a first section 41 and a second section 42. An installation cavity 410 is provided in the first section 41. The installation cavity 410 penetrates the first section 41 along the third direction Y. The optical unit 10 is provided in the installation cavity 410 so as to separate the optical unit 10 from the electrical unit 20 and the outer sheath 30 through the support member 40. At least one side of the first section 41 is connected to a second section 42 along the first direction X. A receiving groove 420 is provided on a side of the second section 42 away from the first section 41. The receiving groove 420 at least partially receives the electrical unit 20, and the electrical unit 20 is clamped between the bottom wall of the receiving groove 420 and the inner wall of the outer sheath 30 along the first direction X, so that the electrical unit 20 is in contact with the second section 42 and the outer sheath 30 at the same time, so that when the flat optical-electrical composite cable 100 is subjected to an external force, the external force is transmitted to the electrical unit 20 with higher strength as much as possible, thereby reducing the magnitude of the stress on the optical unit 10.

[0065] In the second direction Z, the two opposite sides of the second section 42 respectively abut against the inner walls of the outer sheath 30 along the second direction Z, so that when the outer sheath 30 is subjected to an external force along the second direction Z, the external force can be directly transmitted to the second section 42. In the second direction Z, the two opposite sides of the first section 41 are respectively spaced from the inner walls of the outer sheath 30 along the second direction Z, so that when the outer sheath 30 is subjected to an external force along the second direction Z, the external force cannot be directly transmitted to the first section 41.

[0066] In this way, the flat optoelectronic composite cable 100 of the present application is provided with a support member 40 in the outer sheath 30, and the support member 40 is composed of a first section 41 and a second section 42. Along the second direction Z, the opposite sides of the second section 42 both abut against the outer sheath 30, and the opposite sides of the first section 41 are spaced apart from the outer sheath 30, so that when the middle area of ​​the flat optoelectronic composite cable 100 is subjected to force, the external force is transmitted to the second section 42 that is in direct contact with the outer sheath 30, and along the first direction X, the second section 42 presses the electrical unit 20 against the outer sheath 30, and then the second section 42 transmits the external force to the areas at both ends of the electrical unit 20 and the outer sheath 30, thereby avoiding problems such as excessive stress at the location of the optical unit 10 causing the optical unit 10 to break.

[0067] Please combine again Figures 1 to 3 In one embodiment, the number of the electrical units 20 is set to two. Correspondingly, along the first direction X, the two opposite sides of the first section 41 are connected to a second section 42, that is, the number of the second sections 42 is also two, and the two second sections 42 are integrally formed with the first section 41 to improve the structural strength of the support member 40. The two second sections 42 are provided with receiving grooves 420 on one side away from the first section 41, and the two electrical units 20 are partially received in the two receiving grooves 420 respectively. The cross-section of the electrical unit 20 is circular, and the cross-section of the two receiving grooves 420 is semicircular, and the receiving grooves 420 are adapted to the electrical unit 20, so that the section of the electrical unit 20 located in the receiving groove 420 can be close to the groove wall of the receiving groove 420, thereby improving the stability of the electrical unit 20 during installation.

[0068] It is understandable that in other embodiments, the number of the electrical unit 20 may also be one. The number of the second section 42 is one, and one second section 42 is connected to one side of the first section 41 along the first direction X.

[0069] It is understandable that in other embodiments, the number of the electrical units 20 may also be four. Along the first direction X, two electrical units 20 are respectively provided on opposite sides of the support member 40. There are two second sections 42, and both second sections 42 are provided with receiving grooves 420. Each receiving groove 420 completely receives one electrical unit 20 and partially receives another electrical unit 20. The two electrical units 20 are supported against each other and clamped between the outer sheath 30 and the corresponding second section 42.

[0070] In this embodiment, a perforation 43 is provided on the support member 40, and the extension direction of the perforation 43 is parallel to the extension direction of the flat optoelectronic composite cable 100. There are multiple perforations 43, and the cross-sectional shape of the perforations 43 is circular, and the multiple perforations 43 are evenly distributed on the first section 41 and the second section 42. The provision of the perforations 43 can enhance the buffering effect of the support member 40. When stress is transmitted to the position of the perforations 43, it can be released through the perforations 43, thereby preventing the support member 40 from applying excessive external force to the optical unit 10 disposed therein.

[0071] Please combine again Figures 1 to 3 In one embodiment, the cross-section of the outer sheath 30 is substantially in the shape of an elongated strip. Along the first direction X, the length of the outer sheath 30 is greater than its length along the second direction Z.

[0072] The outer sheath 30 has a defined symmetry plane M, which is a plane where the second direction Z and the third direction Y are located, and the center point of the outer sheath 30 is located on the symmetry plane M. With the symmetry plane M as a dividing plane, the regions of the outer sheath 30 on both sides of the symmetry plane M are symmetrically arranged with the symmetry plane M as a reference.

[0073] Furthermore, the material of the outer sheath 30 is polyvinyl chloride or a low-smoke halogen-free mixture, which has certain UV resistance and rat-proof effects. The outer sheath 30 includes a first sheath portion 31, a second sheath portion 32, a third sheath portion 33, and a fourth sheath portion 34 connected end to end in sequence, and the first sheath portion 31, the second sheath portion 32, the third sheath portion 33, and the fourth sheath portion 34 are surrounded to form a cavity 301. The first sheath portion 31, the second sheath portion 32, the third sheath portion 33, and the fourth sheath portion 34 are integrally formed.

[0074] The first sheath portion 31 and the third sheath portion 33 are both arc-shaped, and the extension directions of the first sheath portion 31 and the third sheath portion 33 are both substantially extended along the first direction X. Along the second direction Z, the first sheath portion 31 and the third sheath portion 33 are arranged at intervals, and the first sheath portion 31 and the third sheath portion 33 are arranged symmetrically about the plane where the first direction X and the third direction Y are located. In addition, the first sheath portion 31 and the third sheath portion 33 are both bent toward one side of the support member 40 located in the cavity 301.

[0075] The second sheath portion 32 and the fourth sheath portion 34 are both arc-shaped, and the second sheath portion 32 and the fourth sheath portion 34 are symmetrically arranged with respect to the symmetry plane M. The curvatures of the second sheath portion 32 and the fourth sheath portion 34 are greater than the curvatures of the first sheath portion 31 and the third sheath portion 33. The second sheath portion 32 and the fourth sheath portion 34 are both curved toward a side away from the support member 40.

[0076] Along the second direction Z, both ends of the second sheath portion 32 smoothly connect the left ends of the first sheath portion 31 and the third sheath portion 33. Along the second direction Z, both ends of the fourth sheath portion 34 smoothly connect the right ends of the first sheath portion 31 and the third sheath portion 33.

[0077] In this way, the arc-shaped design of the first sheath portion 31 and the third sheath portion 33 makes the entire outer sheath 30 concave on both sides in the second direction Z. When the outer sheath 30 is subjected to external force in the second direction Z, the external force will be transmitted as much as possible along the first sheath portion 31 and the third sheath portion 33 to the second sheath portion 32 and the fourth sheath portion 34 at both ends of the outer sheath 30, thereby reducing the stress at the first sheath portion 31 and the third sheath portion 33, thereby avoiding the risk of breakage of the optical unit 10 located between the first sheath portion 31 and the third sheath portion 33.

[0078] Please combine again Figures 1 to 3 In one embodiment, the electrical unit 20 includes a conductor 21 and an insulating layer 22 wrapped around the outer circumference of the conductor 21. The conductor 21 is made of metal such as aluminum wire or copper wire, and the insulating layer 22 is made of polyvinyl chloride or a low-smoke halogen-free mixture, which has a certain UV resistance and rat-proof effect. The cross-sectional shape of the insulating layer 22 is circular, and the insulating layers 22 of the two electrical units 20 are of different colors to directly distinguish the two electrical units 20.

[0079] The inner wall of the second sheath portion 32 and the fourth sheath portion 34 close to the support member 40 is set as the second inner wall P3, and the outer wall of the second sheath portion 32 and the fourth sheath portion 34 away from the support member 40 is set as the second outer wall P4. The shape of the second inner wall P3 and the second outer wall P4 is the same as that of the second sheath portion 32 and the fourth sheath portion 34.

[0080] Along the first direction X, the outer surface of the left half of the electric unit 20 located on the left is in close contact with the second inner wall P3 of the second sheath portion 32, and the outer surface of the right half of the electric unit 20 located on the left is in close contact with the groove wall of the corresponding receiving groove 420. Correspondingly, the outer surface of the right half of the electric unit 20 located on the right is in close contact with the second inner wall P3 of the fourth sheath portion 34, and the outer surface of the left half of the electric unit 20 located on the right is in close contact with the groove wall of the corresponding receiving groove 420.

[0081] In this embodiment, the inner wall of the first sheath portion 31 and the third sheath portion 33 on the side close to the support member 40 is set as the first inner wall P1, and the outer wall of the first sheath portion 31 and the third sheath portion 33 on the side away from the support member 40 is set as the first outer wall P2. The shapes of the first outer wall P2 and the first inner wall P1 are both arc-shaped, and the shapes of the first outer wall P2 and the first inner wall P1 are the same as those of the first sheath portion 31 and the third sheath portion 33.

[0082] Along the second direction Z, the surfaces of the second section 42 on the opposite sides are respectively attached to the two first inner walls P1, thereby increasing the contact area between the second section 42 and the outer sheath 30. On the one hand, the external force exerted on the outer sheath 30 is transmitted to the second section 42 more, and on the other hand, excessive stress at the contact point between the second section 42 and the outer sheath 30 is avoided, which may easily damage the outer sheath 30.

[0083] Alternatively, if Figure 1 As shown, in the second direction Z, the size of the second section 42 is larger than that of the first section 41, and the second section 42 protrudes relative to the first section 41. This design allows a concave to be naturally formed at the position of the first section 41 (i.e., the position corresponding to the optical unit 10) when the outer sheath 30 is subsequently formed, thereby reducing the probability of the optical unit 10 being subjected to stress in the first section 41 and reducing the probability of the optical fiber 12 being broken.

[0084] Please combine again Figures 1 to 3 In one embodiment, the cross-sectional shape of the first section 41 is substantially rectangular. Along the second direction Z, both upper and lower ends of the first section 41 do not exceed the second section 42.

[0085] Thus, along the second direction Z, two opposite sides of the first section 41 are spaced apart from the two first inner walls P1 , respectively, to prevent the external force on the first sheath portion 31 and the third sheath portion 33 from being directly transmitted to the first section 41 .

[0086] In particular, along the second direction Z, buffer layers 50 are provided between the opposite sides of the first section 41 and the corresponding two first inner walls P1, and the buffer layers 50 are clamped between the first section 41 and the first inner wall P1. The arrangement of the buffer layer 50 can play a good buffering role when the first sheath portion 31 and the third sheath portion 33 are bent and deformed toward the first section 41 due to external force, so as to prevent the first section 41 from being subjected to excessive external force. The buffer layer 50 can be made of materials such as talcum powder.

[0087] In other embodiments, a release layer may also be disposed between two opposite sides of the first section 41 and the two corresponding first inner walls P1 along the second direction Z to facilitate cable stripping.

[0088] In this embodiment, the outer circumference of the light unit 10 is spaced from the inner circumference of the mounting cavity 410, so that a certain gap is left between the outer circumference of the light unit 10 and the inner circumference of the mounting cavity 410. The existence of the gap can prevent the light unit 10 from being in a close contact state with the first section 41, so that the first section 41 is directly acted on the light unit 10 when the external force transmitted by the outer sheath 30 is directly applied to the light unit 10, causing the light unit 10 to break.

[0089] It is worth noting that the size of the gap cannot be too large. An excessively large gap may cause the light unit 10 to shake in the first section 41 .

[0090] In other embodiments, Figure 3 As shown, the first section 41 includes two subsections 411, and the two subsections 411 are arranged along the first direction X. Along the first direction X, the opposite sides of the two subsections 411 are respectively connected to a second section 42, and the adjacent sides of the two subsections 411 are respectively provided with a subcavity 4101. The two subcavities 4101 are enclosed to form a mounting cavity 410, and along the first direction X, one end of the optical unit 10 is accommodated in one subcavity 4101, and the other end thereof is accommodated in the other subcavity 4101. In addition, along the first direction X, the opposite ends of the optical unit 10 respectively abut against the two subsections 411.

[0091] In this way, dividing the first section 41 into two sub-sections 411 can facilitate taking out the light unit 10 in the installation cavity 410 after splitting the first section 41 .

[0092] It is worth noting that the end surfaces of the two sub-portions 411 at adjacent ends may be spaced apart or may be fitted to each other.

[0093] Please combine again Figure 4 , and see Figure 1 In one embodiment, the flat optoelectronic composite cable 100 further includes a plurality of elastic members 70 . The inner circumference of the first section 41 is provided with a plurality of mounting holes 412 , which are arranged around the optical unit 10 , and the plurality of mounting holes 412 are arranged corresponding to the plurality of elastic members 70 .

[0094] The mounting hole 412 extends from the inner circumference of the first section 41 along the first direction X or the second direction Z toward a side away from the light unit 10. The elastic member 70 is a spring or other element, one end of the elastic member 70 extends into the mounting hole 412 and is elastically connected to the first section 41, and the other end of the elastic member 70 is located outside the mounting hole 412 and elastically supports the light unit 10, so that elastic force is applied to the light unit 10 through the elastic member 70, so that the light unit 10 and the first section 41 are in elastic contact, so as to avoid that when the first section 41 is subjected to external force, the stress on the light unit 10 is too large and the light unit 10 is broken.

[0095] In this embodiment, there are at least four elastic members 70 , which are respectively located on four inner walls of the first section 41 to simultaneously support four side walls of the light unit 10 and ensure that the light unit 10 is evenly stressed.

[0096] Please combine again Figures 1 to 3 In one embodiment, the optical unit 10 includes an inner sheath 11, an optical fiber 12, and a reinforcing member 13, wherein the optical fiber 12 and the reinforcing member 13 are disposed in the inner sheath 11. The cross-sectional shape of the inner sheath 11 is rectangular and matches the shape of the first section 41.

[0097] The optical fiber 12 is a single-mode optical fiber 12, and there are two of them. The reinforcing member 13 is a metal member, and there are two of them. Along the first direction X, the two reinforcing members 13 are arranged on opposite sides of the two optical fibers 12, which can play a good tensile resistance role for the optical unit 10.

[0098] In particular, along the second direction Z, two opposite sides of the inner sheath 11 are provided with wire stripping grooves 110. The cross-sectional shape of the wire stripping groove 110 is "V"-shaped.

[0099] The two reinforcement members 13 are symmetrically arranged with respect to the symmetry plane M, and the two optical fibers 12 are symmetrically arranged with respect to the symmetry plane M. In addition, the planes where the bending lines of the two stripping grooves 110 are located coincide with the symmetry plane M, so that the two optical fibers 12 can be quickly stripped out through the stripping grooves 110 .

[0100] In this embodiment, the number of elastic members 70 is six. Among them, along the first direction X, two elastic members 70 are respectively arranged on both sides of the optical unit 10. Along the second direction Z, two elastic members 70 are arranged on any side of the optical unit 10, and the two elastic members 70 on the same side of the optical unit 10 are respectively arranged on opposite sides of the wire stripping groove 110.
