[0022] Optionally, a second oxygen barrier layer may also be included between the corrugated aluminum sheath and the outer sheath.

[0023] Beneficial effects:

[0024] (1) The elastic bracket, together with the elastomer, is used to increase the compressive strength of the corrugated cable in this scheme, thereby preventing damage to the relevant components of the conductor assembly. The number of sides of the cross-sectional shape of the elastic bracket along the radial direction of the conductor assembly is equal to the number of elastomers, which can be three, four, etc., preferably three. The materials of the elastic bracket and the elastomer can be silicone rubber, fluororubber, etc.

[0025] (2) The corrugated aluminum sheath is used to further increase the compressive strength of the corrugated cable in this scheme, providing double compressive strength and ensuring good compressive strength.

[0026] (3) The first oxygen barrier layer is used to isolate air and has good flame retardant performance. The material of the first oxygen barrier layer can be a low smoke halogen-free flame retardant oxygen barrier strip. The second oxygen barrier layer is used to isolate air and has good flame retardant performance. It works in conjunction with the first oxygen barrier layer to facilitate double oxygen isolation.

[0027] (4) The elliptical shape makes the surface of the elastomer smoother, which makes it easier to increase the contact area between the elastic support of the elastomer and the first oxygen barrier layer, and thus facilitates effective buffering of the pressure from the elastic support and the first oxygen barrier layer.

[0028] (5) The double insulation of the first insulation layer and the second insulation layer makes it easy to ensure good insulation performance. The material of the first insulation layer is preferably ceramicized silicone rubber, and the material of the second insulation layer is preferably mica tape. When burning, the ceramicized silicone rubber forms a dense ceramic shell and carries the mica tape, which has good flame retardant performance. Attached Figure Description

[0034] Example 1

[0035] like Figure 1 This embodiment provides a corrugated cable, including: an elastic support 1; a plurality of elastic bodies 2, one side of which abuts against the elastic support 1; a conductor assembly 3 located inside the elastic body 2; a first oxygen barrier layer 41 wrapped around the other side of the elastic body 2; and a corrugated aluminum sheath 5 and an outer sheath 6 sequentially wrapped around the first oxygen barrier layer 41.

[0036] Specifically, conductor assembly 3 is used to transmit electrical energy; elastic support 1, in conjunction with elastic body 2, is used to increase the compressive strength of the corrugated cable in this solution, thereby preventing damage to the relevant components of conductor assembly 3. The number of sides of the cross-sectional shape of elastic support 1 along the radial direction of conductor assembly 3 is equal to the number of elastic bodies 2, which can be three, four, etc., preferably three. The materials of elastic support 1 and elastic body 2 can be silicone rubber, fluororubber, etc.; the first oxygen barrier layer 41 is used to isolate air and has good flame retardant performance. The material of the first oxygen barrier layer 41 can be low smoke halogen-free flame retardant oxygen barrier tape; the corrugated aluminum sheath 5 is used to further increase the compressive strength of the corrugated cable in this solution, providing double compressive strength to ensure good compressive strength; the outer sheath 6 is used for protection. The material of the outer sheath 6 is preferably flame retardant polyolefin material to further enhance its flame retardant effect.

[0037] Furthermore, such as Figure 1 The elastic support 1 includes: a support body 11, one side of the elastic body 2 abutting against the support body 11; a plurality of extension rods 12, each connected to the support body 11, and a first oxygen barrier layer 41 wrapped around the plurality of extension rods 12.

[0038] Specifically, the support body 11 is used to support the elastic body 2; the extension rod 12 is used to transmit external pressure to the support body 11. The number of extension rods 12 is not limited, but preferably equal to the number of vertices of the cross-sectional shape of the support body 11 along the radial direction of the conductor assembly 3. For example, if the cross-sectional shape is triangular, the number of extension rods 12 is preferably three. The side lengths of the cross-sectional shape of the support body 11 along the radial direction of the conductor assembly 3 are preferably equal, so that the elastic bodies 2 are evenly distributed along the support body 11. At the same time, the extension rods 12 are preferably evenly distributed along the support body 11.

[0039] Furthermore, such as Figure 1 The connection between the support body 11 and the several extension rods 12 is a one-piece molding connection.

[0040] Specifically, the one-piece molding connection facilitates the integrity of the support body 11 and the several extension rods 12, and avoids breakage at the connection between the support body 11 and the several extension rods 12.

[0041] Furthermore, such as Figures 1-2 The cross-sectional shape of the elastomer 2 along the radial direction of the conductor assembly 3 is elliptical.

[0042] Specifically, the elliptical shape facilitates a smooth transition on the surface of the elastomer 2, thereby increasing the contact area between the elastic support 1 and the first oxygen barrier layer 41 of the elastomer 2, and thus effectively buffering the pressure from the elastic support 1 and the first oxygen barrier layer 41.

[0043] Furthermore, such as Figure 1 The grooves on the 5-grooved aluminum sheath are spiral-shaped.

[0044] Specifically, the spiral shape facilitates the uniformity of the groove distribution, thereby increasing the compressive strength uniformity of the grooved aluminum sheath 5.

[0045] Furthermore, such as Figure 2 The conductor assembly 3 includes: a conductor body 33; a first insulating layer 31 and a second insulating layer 32 sequentially wrapped around the conductor body 33; and an elastic body 2 wrapped around the second insulating layer 32.

[0046] Specifically, the conductor body 33 is used to transmit electrical energy. The conductor body 33 can be a solid conductor, a stranded conductor, etc., and the material of the conductor body 33 can be aluminum, copper, etc. The double insulation of the first insulating layer 31 and the second insulating layer 32 helps to ensure good insulation performance. The material of the first insulating layer 31 is preferably ceramicized silicone rubber, and the material of the second insulating layer 32 is preferably mica tape. When burning, the ceramicized silicone rubber forms a dense ceramic shell and supports the mica tape, which has good flame retardant performance.

[0047] Furthermore, such as Figure 2 The thickness of the first insulating layer 31 is greater than the thickness of the second insulating layer 32.

[0048] Specifically, the first insulating layer 31 has a larger thickness, which facilitates the formation of a thicker ceramic shell and provides good flame retardant performance. The second insulating layer 32 has a smaller thickness, which facilitates improved production efficiency.

[0049] Furthermore, such as Figure 1 It also includes a second oxygen barrier layer 42 located between the corrugated aluminum sheath 5 and the outer sheath 6.

[0050] Specifically, the second oxygen barrier layer 42 is used to isolate air, has good flame retardant properties, and works in conjunction with the first oxygen barrier layer 41 to facilitate double oxygen isolation.

[0051] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
