Problems solved by technology

[0003] Cable is a kind of electric energy or signal transmission device, usually composed of several or several groups of wires, cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables , marine cables, mining cables and aluminum alloy cables, etc., they are all composed of single or multi-strand wires and insulating layers, used to connect circuits and electrical appliances, etc., the existing cables have a certain tensile resistance, but Its compressive capacity is average, so it is easy to damage and shorten its life in special working environment, which is not convenient for effective use

Embodiment 1

[0036] Such as figure 1The heat-dissipating cable shown is a compression-resistant and tensile-resistant cable, including at least two cores 12 (four cores 12 are shown in the figure) arranged at the cable core and a function of being sleeved on the outside of the cable core in turn. Layer and outer sheath 1, the core 12 includes a conductor, an insulating layer and a shielding layer that are sheathed in sequence from the inside to the outside; the cable core is provided with a separation support frame 11, and the separation support frame 11 includes a wire The cores 12 have one-to-one corresponding dividers, and a divider is provided between every two adjacent cores 12, and each divider is connected to two oblique support bars 10 at one end facing away from the cable axis. , and the distance between these two oblique support bars 10 gradually increases outwards from the connection end with the partition bar, and the outer end of each of the oblique support bars 10 is connecte...

Embodiment 2

[0041] The difference between this embodiment and embodiment 1 is:

[0042] In this embodiment, the wire core 12 and the spacer strips are twisted together, and the arc-shaped support strips 9 , the wave-shaped buffer strips 5 and the compression-resistant sheath 4 all extend helically along the length direction of the cable. This setting can greatly enhance the strength of the cable, and improve the mechanical properties of the cable such as compression resistance and tensile resistance.

[0043] Others are with embodiment 1.

Embodiment 3

[0045] The difference between this embodiment and embodiment 1 is:

[0046] In this example, if Figure 5 As shown, a gap cavity 14 extending along the length direction of the cable is formed between each concave arc portion 42 and the functional layer, and a reinforcing rope 15 extending along the length direction of the cable is arranged in the gap cavity 14 . The reinforcing rope 15 can be made of nylon material, which can enhance the tensile and compressive strength of the cable.

[0047] In this example, if Figure 5 As shown, the space between the spacer support frame 11 , the oblique support bar 10 , the arc support bar 9 , the wave buffer bar 5 , the anti-pressure sheath 4 and the outside of the wire core 12 is filled with a filler 16 . The filler 16 may use flame retardant materials and / or other functional materials, so as to improve the flame retardant performance and / or other performances of the cable.

[0048] In this embodiment, the first functional layer 2 is ...

Abstract

The invention discloses a compression-resistant and stretch-resistant heat dissipation type cable, and belongs to the technical field of cables. The cable comprises wire cores, a functional layer and an outer sheath; a separation support frame is arranged in the cable core, the separation support frame comprises separation strips in one-to-one correspondence with the wire cores, and one end of each separation strip back to the cable axis is connected with two inclined support strips. The outer side end of each inclined supporting strip is connected with an arc-shaped supporting strip, and a gap is reserved between every two adjacent arc-shaped supporting strips to form a strip-shaped heat dissipation opening. A wave-shaped buffer strip is arranged on the outer side face of each arc-shaped supporting strip, the outer sides of all the wave-shaped buffer strips are sleeved with a compression-resistant sleeve layer, the section of the compression-resistant sleeve layer is in an annular wave shape, the compression-resistant sleeve layer comprises outwards-convex arc-shaped parts and inwards-concave arc-shaped parts which are alternately and intermittently connected along the circumferential side of the compression-resistant sleeve layer, and the compression-resistant sleeve layer is sleeved with the functional layer. The cable has excellent compression resistance and tensile resistance, and heat dissipation of the cable is facilitated.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a compression-resistant and tensile-resistant heat dissipation cable. Background technique [0002] A rope-like object that is usually twisted by several wires or groups of wires is called a cable. Each group of wires is insulated from each other and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation. layer, the cable has the characteristics of internal electrification and external insulation. [0003] Cable is a kind of electric energy or signal transmission device, usually composed of several or several groups of wires, cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables , marine cables, mining cables and aluminum alloy cables, etc., they are all composed of single or multi-strand wires and insulati...
