[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figures 1 to 3 As shown, it is an embodiment of the utility model, which relates to a pressure-resistant control line, including a control line body 10, the control line body 10 includes a pressure-resistant protective layer 20, a plurality of conductors 11, and the plurality of conductors 11 are arranged inside the pressure-resistant protective layer 20; the pressure-resistant protective layer 20 includes an insulating layer 30, a first pressure-resistant layer 40, an armor layer 50, a shielding layer 60, a fireproof layer 70, a second pressure-resistant layer 80 and a jacket layer 90; the plurality of conductors 11 are arranged inside the insulating layer 30; The insulating layer 30 is arranged on the inner side of the first pressure-resistant layer 40; the first pressure-resistant layer 40 is arranged on the inner side of the armor layer 50, and the first pressure-resistant layer 40 includes a plurality of first buffer components 41; the armor layer 50 is arranged on the inner side of the shielding layer 60; the shielding layer 60 is arranged on the inner side of the fireproof layer 70; the fireproof layer 70 is arranged on the inner side of the second pressure-resistant layer 80; the second pressure-resistant layer 80 is arranged on the inner side of the outer jacket layer 90, and the second pressure-resistant layer 80 includes a plurality of second buffer components 81.

[0028] Furthermore, if Figure 3 As shown, the control line body 10 further includes a male plug 12 and a plurality of terminals 13, one end of the male plug 12 is connected to the conductor 11, and the end of the conductor 11 away from the male plug 12 is connected to the terminal 13; a marking sleeve 14 is sleeved on one side of the conductor 11 close to the terminal 13. Specifically, the terminal 13 can be accurately connected to the corresponding connection point on the device through the marking sleeve 14 to ensure stable data transmission.

[0029] Furthermore, if Figure 1 As shown, the insulating layer 30 is an elastic silicone insulating layer 30. Specifically, the structure of the insulating layer 30 makes the buffering effect when the cable is squeezed better, so that the use performance of the cable is better.

[0030] Furthermore, if Figure 1 As shown, the first buffers 41 are distributed in an array around the insulating layer 30 and connected in sequence, and the first buffers 41 are arc-shaped elastic members. Specifically, one side of the arc-shaped protrusion of the first buffer 41 faces the insulating layer 30, and the other side faces the armor layer 50. When the cable is subjected to external force, the external force is transmitted to the first pressure-resistant layer 40. The first buffer 41 of the first pressure-resistant layer 40 is deformed under the action of the force, and expands to both sides with the protrusion point as the center, dispersing the force to both sides of the first buffer 41. The cross-sectional shape of the first buffer 41 changes to an ellipse or a nearly ellipse under the action of the force, and the force of the force point is transferred to both sides of the cable, thereby reducing the extrusion of the internal structure of the cable.

[0031] Furthermore, if Figure 1 As shown, the armor layer 50 is one of a steel wire armor layer 50 or a stainless steel armor layer 50. Specifically, the steel wire armor layer 50 or the stainless steel armor layer 50 is resistant to mechanical damage, greatly enhances the strength of the control line, and increases the service life.

[0032] Furthermore, if Figure 1 and Figure 2 As shown, the shielding layer 60 includes a PET layer 61 and an aluminum foil layer 62, and the aluminum foil layer 62 is arranged on the outside of the PET layer 61. Specifically, PET (polyethylene terephthalate) has excellent physical and mechanical properties and excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good. By coating the aluminum foil layer 62 on one side, it plays an anti-interference shielding role, further improving the stability of signal transmission.

[0033] Furthermore, if Figure 1As shown, the fireproof layer 70 is a ceramic polyolefin fireproof layer 70. Specifically, ceramic polyolefin is used. In the flame ablation test, this composite material can work normally for 90-180 minutes without short circuit or disconnection. Once a fire occurs outside, the first fireproof layer 70 close to the fire source generates a ceramic-like hard shell, which can resist indirect mechanical vibration and water spray at the fire scene, ensure the smooth flow of power and communication lines, extend the service life of the cable, and further enhance the impact resistance and flame retardancy of the cable.

[0034] Furthermore, if Figure 1 As shown, the plurality of first buffer members 41 are arranged in an array around the fireproof layer 70 and connected in sequence, and the first buffer members 41 are conical rubber blocks. Specifically, the second pressure-resistant layer 80 is composed of a plurality of first buffer members 41 connected together, and the first buffer members 41 can not only play a role in pressure resistance, but also play a role in buffering due to the conical design of the first buffer members 41, and there is a certain buffer space between adjacent first buffer members 41, which can achieve a lasting pressure resistance effect.

[0035] Furthermore, if Figure 1 As shown, the outer jacket layer 90 is a brominated butyl rubber layer. Specifically, brominated butyl rubber has the advantages of good wear resistance, high physical strength, excellent aging resistance and heat resistance, and can effectively improve the wear resistance and heat resistance of the cable.

[0036] The utility model is provided with a first pressure-resistant layer 40 and a second pressure-resistant layer 80, and a double pressure-resistant buffer structure is introduced into the structure, which effectively improves the pressure resistance of the cable; an armor layer 50 is provided to improve the use strength of the cable and extend its service life; a shielding layer 60 is provided to play an anti-interference shielding role and further improve the stability of signal transmission; a fireproof layer 70 is provided to enhance the flame retardancy of the cable; an insulating layer 30 is provided to effectively protect the conductor 11 and improve safety; and a jacket layer 90 is provided to improve the wear resistance and heat resistance of the cable.

[0037] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
