Description

Technical Field

[0001] The utility model relates to the technical field of signal lines, in particular to an environmentally friendly tensile-resistant signal line structure. Background Art

[0002] Signal lines mainly refer to the lines used to transmit sensor information and control information in electrical control circuits. Signal lines are often composed of multiple cables as one or more transmission lines, or they can be printed lines arranged in printed circuit boards. With the continuous advancement of technology and applications, signal lines have evolved from metal carriers to other carriers, such as optical cables.

[0003] At present, in the use of signal lines, since relatively low-priced and environmentally unfriendly materials are generally used in signal lines (such materials are difficult to pass the low-smoke performance requirements and halogen-free performance requirements), especially in the use of outer layer and insulation layer materials, the existing signal lines have poor environmental performance; in addition, since multiple wire cores are arranged inside the signal line (the signal line itself has poor tensile strength under this structure, and is prone to the risk of rupture when bent by a large force), the tensile strength of the existing signal line is poor, and the signal line is unevenly stressed, and long-term use will reduce its service life;

[0004] Based on the above problems, we propose an environmentally friendly tensile signal line structure. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides an environmentally friendly tensile-resistant signal line structure, which, after being improved, can effectively solve the problems raised in the above-mentioned background technology.

[0006] The technical solution of the utility model is:

[0007] An environmentally friendly tensile-resistant signal line structure comprises an outer layer and a signal line;

[0008] A plurality of signal lines are arranged inside the outer layer, and the signal lines are arranged sequentially from the inside to the outside with a conductor layer, an insulating layer, a first shielding layer and a middle layer;

[0009] The outer side of the signal line located at the center is coated with a tensile layer;

[0010] The tensile layer is a Kevlar braided layer, the middle cladding layer and the outer cladding layer are both LSZH plastic layers, and the insulating layer is a FMPE plastic layer.

[0011] Furthermore, the conductor layer is a bare copper wire layer, and the first shielding layer is a tinned copper braided layer.

[0012] Furthermore, the number of signal lines is 21, and the signal lines are arranged in layers around a circle with the center of the signal line structure as the center.

[0013] Furthermore, a tape layer, a second shielding layer and a third shielding layer are sequentially arranged on the inner side of the outer layer.

[0014] Furthermore, the wrapping layer is a Mylar plastic layer.

[0015] Furthermore, the second shielding layer is an aluminum foil layer.

[0016] Furthermore, the third shielding layer is a copper wire mesh layer.

[0017] The beneficial effects of the utility model are:

[0018] Compared with the prior art, the utility model is provided with an insulating layer, a middle layer and an outer layer, and the materials used are FMPE plastic and LSZH plastic. Such materials are extremely environmentally friendly and can pass the low smoke performance requirements and halogen-free performance requirements, so that the environmental performance of the entire signal structure is better; in addition, a tensile layer is provided at the center position of the signal line structure, which greatly enhances the tensile performance of the signal line structure and makes the signal line structure more evenly stressed, and can withstand a force of 10kg and operate normally, thereby greatly improving the use quality and life of the signal line structure.

[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0022] like Figure 1 As shown,

[0023] An environmentally friendly tensile signal line structure comprises an outer layer 1 and a signal line 2; a plurality of signal lines 2 are arranged inside the outer layer 1, and the signal line 2 is sequentially provided with a conductor layer 3, an insulating layer 4, a first shielding layer 5 and a middle layer 6 from the inside to the outside; the outer side of the signal line 2 located at the center is coated with a tensile layer 7; in the present application, specifically, the tensile layer 7 is a Kevlar braided layer, the middle layer 6 and the outer layer 1 are both LSZH plastic layers, and the insulating layer 4 is an FMPE plastic layer; the LSZH plastic and FMPE plastic used are both environmentally friendly materials, which can meet the requirements of GB / T17651.2 through low smoke performance and meet the requirements of GB / T17650.1 and GB / T17650.2 through halogen-free performance, so that the environmental protection of the entire signal structure is improved. It can be better; it is worth mentioning that, in general signal line structures, except for the insulating layer 4 and each outer layer, the materials used in other layers have environmentally friendly properties. Therefore, in the present application, the materials of the middle layer 6, the outer layer 1 and the insulating layer 4 are defined as environmentally friendly materials, thereby making the environmental performance of the signal line structure better; in addition, a tensile layer 7 is arranged at the center position of the signal line structure, and the tensile layer 7 is coated on the signal line 2 at the center position, and the remaining 20 signal lines 2 are layered with the center of the signal line structure as the center circle, which also achieves a symmetrical effect, thereby greatly enhancing the tensile performance of the line structure, and making the line structure more evenly stressed, able to withstand a force of 10kg and operate normally, with better quality and longer service life.

[0024] As a preferred embodiment, the conductor layer 3 is a bare copper wire layer, and the first shielding layer 5 is a tinned copper braided layer. The tinned copper braided layer has the function of resisting signal interference, which can avoid signal interference between the signal lines 2, thereby ensuring the signal transmission quality of each signal line 2.

[0025] As a preferred embodiment, the number of signal lines 2 is 21, and they are arranged in layers around the center of the signal line structure. The purpose of this design is to enhance the tensile performance and to make the force more uniform.

[0026] As a preferred embodiment; the inner side of the outer layer 1 is also provided with a tape layer 8, a second shielding layer 9 and a third shielding layer 10 in sequence; it can be understood that the tape layer 8 has the function of protecting the signal line 2 and the second shielding layer 9, the tape layer 8 is soft and wear-resistant, and can separate the signal line 2 and the second shielding layer 9, and prevent friction damage between the outermost layer 6 of the signal line 2 and the second shielding layer 9, thereby ensuring the anti-signal interference effect of the second shielding layer 9; in addition, the second shielding layer 9 and the third shielding layer 10 can effectively prevent external signals from interfering with the internal signal line 2, thereby further ensuring the line number transmission quality of the signal line 2.

[0027] As a preferred embodiment, the wrapping layer 8 is a Mylar plastic layer.

[0028] As a preferred embodiment, the second shielding layer 9 is an aluminum foil layer.

[0029] As a preferred implementation, the third shielding layer 10 is a copper wire mesh layer.

[0030] In the present application, the 21 signal lines 2 also constitute 21 coaxial line units, and the coaxial line means that the conductor layer 3 is the first circular layer, the insulating layer 4 is the second circular layer, and the first shielding layer 5 is the third circular layer. The three layers can constitute the coaxial line structure of the signal line 2; this line passes through 21 coaxial lines with a characteristic impedance of 75Ω and is a circularly symmetrical structure, which greatly enhances the high-frequency signal transmission capability of this line and can control the high-frequency signal transmission of the 21 signal lines 2 (there are two ways to control the signal line 2: one is to control it through the signal control line, and the other is to control it through the control device connected to the signal line 2, and the present application belongs to the latter) and because of the coaxial output method, the transmission distance of the signal line structure is longer, and the high-frequency signal transmission distance can be more than 3 kilometers.

[0031] It should be pointed out that the main problems existing in the prior art are: the existing signal lines have poor environmental performance, poor tensile strength, and uneven force on the signal lines, which will reduce their service life if used for a long time;

[0032] Therefore, through the improvements of the present application, not only the environmental protection performance of the entire signal structure is improved; but also a tensile layer 7 is provided at the center position of the signal line structure, which greatly enhances the tensile performance of the signal line structure and makes the force on the signal line structure more uniform, and can withstand a force of 10kg and operate normally, thereby greatly improving the use quality and life of the signal line structure.

[0033] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
