Detailed Description

In order to make those skilled in the art understand the technical solutions in the embodiments of the present invention better and make the above objects, features and advantages of the embodiments of the present invention more obvious and understandable, the following description of the technical solutions in the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

In the description of the present invention, unless otherwise specified and limited, it is to be noted that the term "connected" is to be interpreted broadly, for example, it may be mechanically or electrically connected, or it may be connected between two elements, directly or indirectly through an intermediate medium, and specific meanings of the terms may be understood by those skilled in the art according to specific situations.

Referring to fig. 1, it is a perspective view of the structure of one embodiment of the wave absorbing cable after being peeled off layer by layer.

Therefore, the wave-absorbing material layer is equivalent to a heat-insulating layer in the non-working state of the wave-absorbing cable, and the wave-absorbing cable is prevented from being damaged due to too low ambient temperature. In addition, when the allowable external electromagnetic environment of the wave-absorbing cable is matched with the allowable working temperature range of the conductor assembly, the wave-absorbing material layer absorbs external electromagnetic waves in the allowable external electromagnetic environment of the wave-absorbing cable in a non-working state, and the temperature of the outer wall of the wave-absorbing cable is smaller than the maximum value of the allowable working temperature range of the conductor assembly and larger than the minimum value of the allowable working temperature range of the conductor assembly. When the wave-absorbing cable enters the working state, the conductor assembly can generate certain heat, the heat can be transferred to the inner wall of the wave-absorbing material layer through the wave-absorbing shielding layer, meanwhile, the electromagnetic wave generated by the conductor assembly can also be transferred to the inner wall of the wave-absorbing material layer through the wave-absorbing shielding layer, the inner wall of the wave-absorbing material layer can generate certain heat after receiving the electromagnetic wave of the conductor assembly, the heat and the heat transferred by the conductor assembly can raise the temperature of the inner wall of the wave-absorbing material layer, when the temperature of the inner wall of the wave-absorbing material layer is lower than the temperature of the outer wall of the wave-absorbing material layer, although the heat can be transferred towards the direction of the conductor assembly, because the temperature reached by the outer wall of the wave-absorbing material layer is lower than the maximum value of the allowable working temperature range of the, the heat can outwards be transmitted to can guarantee conductor assembly's normal heat dissipation, it can be seen that no matter what kind of relation is presented to the inner wall temperature and the outer wall temperature of absorbing material layer, can both guarantee that conductor assembly is in its allows operating temperature within range, and because absorbing material layer is outmost, consequently can realize dispelling the heat fast. The utility model discloses in owing to wrap up outward in proper order at the conductor subassembly and inhale ripples shielding layer and absorbing material layer, consequently can realize effective electromagnetic shield. Therefore, the utility model discloses inhale ripples cable structure is very simple, and can realize normal use, normal heat dissipation and the effective shielding of electromagnetism under the low temperature environment.

According to the above embodiment, the utility model discloses a wear to establish in the ripples shielding layer at conductor assembly, at the outer cladding of ripples shielding layer wave-absorbing material layer, make the ripples shielding material layer as outmost, the heat that the electromagnetic wave produced in the external environment is absorbed in the ripples shielding material layer, even if can make the cable also can normally work under the low temperature environment, work as the normal work of ripples cable, when the inner wall temperature on ripples shielding material layer is greater than outer wall temperature, the heat can outwards give off, thereby can realize the normal heat dissipation of cable, and effective electromagnetic shield can be realized to ripples shielding layer and ripples shielding material layer.

In addition, in the present embodiment, the number of conductors in each conductor assembly 5 may be plural, and the number of the conductor assemblies 5 may be three. The stranded wire is clamped in the wave-absorbing shielding layer 3 and is abutted against the inner wall of the wave-absorbing shielding layer 3. The utility model discloses a make the stranded conductor card establish in inhaling the wave-shield layer, make the part on the stranded conductor and inhale the wave-shield layer inner wall butt, and there is the part clearance between the conductor assembly in the stranded conductor and between conductor assembly and the ripples shielding layer, even if so receive the external environment influence, it buckles or tensile deformation to inhale wave-shield layer and ripples material layer appearance, also can change the relative position relation between conductor assembly and the ripples shielding layer, and can not buckle or stretch to conductor assembly, therefore can external environment effort lead to the fact the influence to conductor assembly, avoid conductor assembly to damage under the external environment effort.
