Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a silicone rubber high-temperature resistant control cable. Background Technology

[0002] Control cables are cables used to connect various control devices and control systems to transmit signals and power for the control and monitoring of equipment. Control cables are widely used in various fields and play an important role in helping to achieve automated, intelligent, and efficient control and management.

[0003] However, existing high-temperature resistant silicone rubber control cables lack sufficient strength, are easily deformed under pressure, and have poor flame retardant properties, readily releasing large amounts of toxic gases during combustion. Therefore, they do not meet current requirements. To address this, we have proposed a high-temperature resistant silicone rubber control cable. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-temperature resistant silicone rubber control cable.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A high-temperature resistant silicone rubber control cable includes a conductor protective layer, a protective sleeve on the outside of the conductor protective layer, an aluminum foil shielding layer on the outer surface of the protective sleeve, an inner silicone rubber sleeve on the outside of the aluminum foil shielding layer, and an outer silicone rubber sleeve on the outside of the inner silicone rubber sleeve.

[0007] Preferably, the outer surface of the outer silicone rubber sleeve is provided with a hydrophobic coating, an expanded graphite layer is provided between the inner silicone rubber sleeve and the outer silicone rubber sleeve, and an elastic rubber mesh is provided on the inner side of the inner silicone rubber sleeve.

[0008] Preferably, a filling layer is provided on the inner side of the conductor protective layer, an elastic support block is provided on the inner side of the filling layer, a second conductor protective sleeve is provided at the middle position of the elastic support block, a first conductor protective sleeve is uniformly provided on the outer side of the second conductor protective sleeve, conductors are provided on the inner sides of the second conductor protective sleeve and the first conductor protective sleeve, and an insulating layer is provided on the inner surface of the second conductor protective sleeve and the first conductor protective sleeve.

[0009] Preferably, the inner surface of the aluminum foil shielding layer is fixed to the outer surface of the protective sleeve by adhesive bonding.

[0010] Preferably, the conductor is made of multiple strands of copper wire twisted together.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model provides an outer silicone rubber sleeve and an inner silicone rubber sleeve on the outside of the conductor protective layer. The strength of the cable is increased by using the silicone rubber sleeves on both sides. An expanded graphite layer is set between the inner and outer silicone rubber sleeves, and an elastic rubber mesh is set on the inner side of the inner silicone rubber sleeve. The expanded graphite layer can form a tough char layer on the outer surface when it catches fire, thereby achieving a flame retardant effect, reducing the burning time, and reducing the toxic gases produced by combustion. The elastic rubber mesh can recover after the cable is squeezed, reducing the deformation of the cable and improving the working strength of the cable.

[0013] 2. This utility model improves the cable's performance by setting an elastic support block inside the conductor protective layer, thereby increasing the support effect on the conductor protective layer, reducing the impact of compression on the internal conductor, and improving the cable's working efficiency.

It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figure 1 As shown, the high-temperature resistant silicone rubber control cable of this utility model includes a conductor protective layer 5, a protective sleeve 4 is provided on the outside of the conductor protective layer 5, an aluminum foil shielding layer 3 is provided on the outer surface of the protective sleeve 4, an inner silicone rubber sleeve 2 is provided on the outside of the aluminum foil shielding layer 3, and an outer silicone rubber sleeve 1 is provided on the outside of the inner silicone rubber sleeve 2.

The expanded graphite layer 7 can form a tough char layer on the outer surface when the fire is lit, thereby achieving a flame retardant effect, reducing the burning time, and reducing the toxic gases produced by the combustion. The elastic rubber mesh 8 can recover after the cable is squeezed, reducing the deformation of the cable and improving the working strength of the cable.

[0021] As a preferred technical solution in this embodiment, such as Figure 3 As shown, a filling layer 9 is provided on the inner side of the conductor protective layer 5, and an elastic support block 10 is provided on the inner side of the filling layer 9. A second conductor protective sleeve 12 is provided at the middle position of the elastic support block 10, and a first conductor protective sleeve 11 is uniformly provided on the outer side of the second conductor protective sleeve 12. A conductor 13 is provided on the inner side of the second conductor protective sleeve 12 and the first conductor protective sleeve 11.

[0022] Working principle: In use, an outer silicone rubber sleeve 1 and an inner silicone rubber sleeve 2 are set on the outside of the conductor protection layer 5. The strength of the cable is increased by the silicone rubber sleeves on both sides. An expanded graphite layer 7 is set between the inner silicone rubber sleeve 2 and the outer silicone rubber sleeve 1, and an elastic rubber mesh 8 is set on the inner side of the inner silicone rubber sleeve 2. The expanded graphite layer 7 can form a tough carbon layer on the outer surface when it is on fire, thereby achieving a flame retardant effect, reducing the burning time, and reducing the toxic gases produced by combustion. The elastic rubber mesh 8 can recover after the cable is squeezed, reducing the deformation of the cable and improving the working strength of the cable. An elastic support block 10 is set on the inner side of the conductor protection layer 5. The elastic support block 10 increases the support effect of the conductor protection layer 5, reduces the impact of compression on the internal conductor 13, and improves the working performance of the cable.
