Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a tensile-resistant insulated cable. Background Art

[0002] A cable is a conductor that transmits power or information from one location to another, consisting of one or more mutually insulated conductors covered with an insulating layer. It is typically a rope-like cable made up of several or several groups of at least two conductors twisted together. Each group of conductors is insulated from each other and often twisted around a central core. The entire cable is covered with a highly insulating layer. Cables are characterized by internal conduction and external insulation.

[0003] In the prior art, a Chinese patent with publication number CN211879091U discloses a water-resistant and moisture-proof insulated cable, comprising an inner conductor, the outer portion of which is sequentially coated with a fluororubber inner moisture-proof layer, an inner semi-conductive shielding layer, a silane grafted cross-linked low-density polyethylene insulation layer, an outer semi-conductive shielding layer, a fluororubber outer moisture-proof layer, a polypropylene moisture-absorbing layer, a copper-plastic composite tape wrapping layer, a shielded mesh conductor layer, a PTFE wrapping tape layer, and an outer sheath. A polypropylene moisture-absorbing core material is filled between the inner conductor and the fluororubber inner moisture-proof layer. The thickness of the fluororubber inner moisture-proof layer and the fluororubber outer moisture-proof layer is 0.5 mm to 3 mm, and the fluororubber inner moisture-proof layer and the fluororubber outer moisture-proof layer are both at least two fluororubber layers laminated into an integrated structure. The cable has excellent waterproof and moisture-proof performance, delays water tree aging phenomenon, has excellent insulation performance, stable electrical shielding performance, and better adaptability to the laying environment. The solution has excellent waterproof and moisture-proof performance, delays water tree aging phenomenon, has excellent insulation performance, stable electrical shielding performance, and better adaptability to the laying environment.

[0004] However, the above solution still has some shortcomings. For example, in actual application, it is inconvenient to perform moisture-proof operations on it. During the installation and use of the cable, moisture will enter the inside of the cable, which will affect the subsequent use of the cable. Since water is conductive, it may cause current leakage, and also affect the safe use of the cable. In view of this, the utility model proposes a tensile-resistant insulated cable.

[0008] The inner wall of the rubber sleeve is provided with a card block, one side of the card block is set to be arc-shaped, and a limit plate is fixedly installed on one side of the arc surface of the card block.

[0012] Preferably, the surface of the cable shielding sleeve is provided with a waterproof sleeve, and the inner wall of the waterproof sleeve is fixedly connected to the surface of the cable shielding sleeve.

[0013] Preferably, the inner wall of the limiting plate contacts the surface of the waterproof cover, and one side of the limiting plate is configured to be arc-shaped, and the arc on the limiting plate is adapted to the surface of the waterproof cover.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model uses a spring to reset the arc plate, so that the arc plate contacts the surface of the clamping block, so that the limit plate on the clamping block is clamped with the surface of the waterproof sleeve, thereby increasing the overall stability of the cable and the strength of the cable, making it easier for the staff to use it later and improving the efficiency of the cable.
