Description

Technical Field

[0001] The utility model relates to the technical field of signal lines, in particular to a high and low temperature resistant signal line. Background Art

[0002] Signal wire is a kind of wire used for data signal transmission. At present, the main problems of existing signal wires in use are: first, the high and low temperature resistance is poor, and it is difficult to use in harsh environments, resulting in a small range of use of such signal wires; second, the shielding layer on the internal signal wire core is easily damaged by friction during the continuous bending of the wire, thereby reducing the signal wire's ability to resist signal interference;

[0003] Based on the above problems, we propose a high and low temperature resistant signal line. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a high and low temperature resistant signal line, which can effectively solve the problems raised in the above background technology after being improved.

[0005] The technical solution of the utility model is:

[0006] A high and low temperature resistant signal line, comprising an outer layer and a signal line;

[0007] A signal line is arranged inside the outer layer, and the outer layer is a silicone layer;

[0008] The signal line is provided with a first conductor, a first insulating layer, a first shielding layer, a second shielding layer and an isolation layer in sequence from the inside to the outside; the first insulating layer is a FEP plastic layer; and the isolation layer is a Mylar plastic layer.

[0009] Furthermore, a signal control line and a filling layer are arranged inside the outer layer; the signal control line is provided with a second conductor and a second insulating layer in sequence from the inside to the outside.

[0010] Furthermore, the first conductor and the second conductor are both tinned copper wires; the first shielding layer and the second shielding layer are both tinned copper wire braided layers; the second insulating layer is a FEP plastic layer; and the filling layer is a cotton thread layer.

[0011] Furthermore, a tape layer is provided on the inner side of the outer layer.

[0012] Furthermore, the wrapping layer is a non-woven fabric layer.

[0013] The beneficial effects of the utility model are:

[0014] Compared with the prior art, the utility model adopts silicone as the outer layer and FEP plastic as the insulating layer of the signal line and the signal control line, so that the line has better high and low temperature resistance, which can reach the range of -60-200 degrees Celsius, and can be used in harsh environments, thereby expanding the use range of the line; in addition, by providing an isolation layer, the isolation layer is made of Mylar plastic, which is soft and durable, and can effectively prevent the second shielding layer from being squeezed and worn, thereby ensuring the shielding effect of the first shielding layer and the second shielding layer, thereby improving the line's ability to resist signal interference, and has strong practicality.

DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1 As shown,

[0019] A high and low temperature resistant signal line, comprising an outer layer 1 and a signal line 2;

[0020] A signal line 2 is arranged inside the outer layer 1, and the outer layer 1 is a silica gel layer;

[0021] The signal line 2 is provided with a first conductor 3, a first insulating layer 4, a first shielding layer 5, a second shielding layer 6 and an isolation layer 7 in sequence from the inside to the outside; the first insulating layer 4 is an FEP plastic layer; the isolation layer 7 is a Mylar plastic layer; in the present embodiment, the signal line 2 comprises a low-power data transmission line and a high-power data transmission line, the main difference between the low-power data transmission line and the high-power data transmission line is the different size of the first conductor 3 used, the low-power data transmission line can be used for small data signal transmission, and the high-power data transmission line can be used for large data signal transmission, so that the signal line 2 has the function of an integrated data transmission line, and optimizes the structure of the signal line 2, realizes high-power and low-power data transmission at the same time, and has a better use effect; in addition, the structural arrangement of the signal line 2 further saves the space of the line, thereby reducing the cost of the wire; it is worth mentioning that silicone and FEP plastic themselves have strong and stable high and low temperature resistance, and are arranged on the outer layer 1 and the insulation layer of each line, which can achieve high and low temperature resistance inside and outside, thereby achieving the high and low temperature resistance performance of the line.

[0022] As a preferred embodiment; a signal control line 8 and a filling layer 9 are also arranged inside the outer layer 1; the signal control line 8 is sequentially provided with a second conductor 10 and a second insulating layer 11 from the inside to the outside; by providing the filling layer 9, the filling layer 9 is a soft material, which not only has the function of filling the main line into a circular shape, but also helps the signal line 2 to have a certain relative sliding space when the main line is subjected to force, and thus helps the main line to resist the torsion and bending forces imposed on it by the outside world, so that the main line has strong tensile resistance, compression resistance and bending resistance, and can perform data transmission in the case of complex movement; at the same time, the filling layer 9 is in a full state; in addition By providing a signal control line 8, the number of signal control lines 8 is several, which can correspond one to one to the control of the signal line 2 (the signal line 2 includes a low-power data transmission line and a high-power data transmission line. In actual use, there are 5 low-power data transmission lines and 3 high-power data transmission lines, but it is not limited to this number; and the number of signal control lines 8 is 8, which are controlled one to one). On the one hand, it has an integration effect, reduces the cost of wires and improves the appearance of the equipment connection wires. On the other hand, it can control the signal transmission switch of the signal line 2, so that the entire line can perform various complex types of data transmission according to the equipment control instructions.

[0023] Specifically, the first conductor 3 and the second conductor 10 are both tinned copper wires; the first shielding layer 5 and the second shielding layer 6 are both tinned copper wire braided layers; the second insulating layer 11 is a FEP plastic layer; the filling layer 9 is a cotton thread layer; it can be understood that the first conductor 3 and the second conductor 10 are both made of extremely fine tinned copper wires, and the corresponding insulating layers are all made of FEP plastic, so that the conductors are resistant to bending; in addition, the double-layer shielding layer makes the line have a strong ability to resist signal interference, and through the protection of the isolation layer 7, the signal shielding effect can be maintained during long-term use or when bent.

[0024] As a preferred embodiment, a tape layer 12 is also provided on the inner side of the outer layer 1, and the tape layer 12 is a non-woven fabric layer. It can be understood that the tape layer 12 has the performance of wrapping a round wire to ensure the appearance of the wire.

[0025] It should be pointed out that the main problems in the prior art are: poor high and low temperature resistance, difficult to use in harsh environments, resulting in a small range of use of such signal lines; and, in the process of continuous bending of the wires, the shielding layer on the internal signal wire core is easily damaged by friction, thereby reducing the signal line's ability to resist signal interference;

[0026] Therefore, through the improvement of the present application, silicone is used as the outer layer 1, and FEP plastic is used as the insulating layer of the signal line 2 and the signal control line 8, so that the line has better resistance to high and low temperatures, and by providing an isolation layer 7, it can effectively prevent the second shielding layer 6 from being squeezed and worn, thereby ensuring the shielding effect of the first shielding layer 5 and the second shielding layer 6, and thus improving the ability of the line to resist signal interference.

[0027] 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.
