Cable connection member and cable connection structure
A cable connection member comprises a cold shrink tube, an impervious layer provided inside the cold shrink tube, and a cushion layer provided inside the cold shrink tube and bonded to an entire surface of the impervious layer.
1 . A cable connection member comprising:
a cold shrink tube;
an impervious layer provided inside the cold shrink tube; and
a cushion layer provided inside the cold shrink tube;
wherein the cushion layer is configured by a foam tape and is bonded to an entire surface of the impervious layer.
2 . The cable connection member according to claim 1 , wherein the cushion layer has a thickness of 1 mm or more and 5 mm or less.
3 . The cable connection member according to claim 1 , wherein the cushion layer has a 25% compressive stress of 30 N/cm 2 or less.
4 . The cable connection member according to claim 1 , wherein a base material of the cushion layer has a shear strength of 150 N/cm 2 or more.
5 . The cable connection member according to claim 1 , wherein the cushion layer has a compression set of 80% or less.
6 . The cable connection member according to claim 1 , wherein the impervious layer is configured by a layered body of a metal and a resin.
7 . The cable connection member according to claim 1 , wherein the cold shrink tube constitutes an insulating tube of a cable connection portion attached to an end portion of a cable.
8 . The cable connection member according to claim 1 , wherein:
the cushion layer is provided inside the cold shrink tube; and
the impervious layer is provided inside the cushion layer.
9 . The cable connection member according to claim 1 , wherein:
the cold shrink tube includes an inner layer and an outer layer located outside the inner layer; and
the cushion layer and the impervious layer are provided between the inner layer and the outer layer.
10 . A cable connection structure comprising
an insulating tube of a cable connection portion attached to an end portion of a cable, wherein a cable connection member according to claim 1 constitutes the insulating tube.
11 . The cable connection structure according to claim 10 , comprising:
an outer cold shrink tube covering at least a portion of the cable connection portion;
a cushion layer provided inside the outer cold shrink tube; and
an impervious layer provided inside the cushion layer.
12 . The cable connection structure according to claim 11 , comprising an inner cold shrink tube provided inside the outer cold shrink tube, wherein the inner cold shrink tube includes:
an inner layer and an outer layer located outside the inner layer;
an impervious layer provided between the inner layer and the outer layer; and
a cushion layer provided between the outer layer and the impervious layer.
13 . The cable connection structure according to claim 11 , comprising a sheath cover member that covers the outer cold shrink tube and a cable sheath of the cable.
14 . A cable connection structure comprising the cable connection portion of claim 1 attached to an end portion of a cable, the cable connection structure comprising a sheath cover member that covers a cable sheath of the cable and the cable connection portion.
15 . The cable connection structure according to claim 14 , comprising a band member attached to the cable sheath and located inside the sheath cover member.
