Background technology
At present; ruggedized cable is as the signal connecting line between each electric appliances, instrument and automatics; be mainly used in controlling, the various effect such as Signal transmissions in the monitoring occasion such as interlock circuit and protection circuit and transfer control signal, be widely used in the economic field that various industrial and mining enterprises, communications and transportation etc. are important.Existing cable in use can produce a large amount of heat energy, if these heat energy can not be vaporized useful life and fail safe that the external world can have a strong impact on cable fast; And cable is easily subject to extraneous extruding in underground, the central part cracking of cable core and insulating sleeve likely can be caused after a long time use and impact uses; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of ruggedized cable, and it has, and structure is simple, good heat dissipation effect and the strong feature of anti-pressure ability.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of ruggedized cable, and it comprises pipe in oversheath, radiating sleeve, armouring cover, insulation inner sheath, PE foamed, cable core and resistance to compression; The outer wall of described radiating sleeve is provided with heat radiation projection, and its inwall is provided with heat conduction projection, described heat radiation projection and the heat radiation recess male-female engagement on oversheath inwall, the protruding heat conduction recess male-female engagement overlapped with armouring on outer wall of described heat conduction; The inwall of described armouring cover is fitted with insulation inner sheath; Be provided with chamber in described insulation inner sheath, described cable core and PE foamed are arranged in chamber and PE foamed is coated on the side face of cable core; Be set on the central part of insulation inner sheath in described resistance to compression, and be provided with resistance to compression muscle, the position of described resistance to compression muscle is relative with the position of cable core.
The number of described cable core is four, and it is distributed in insulation inner sheath, and the number of described resistance to compression muscle is similarly four, and the central point of cable core is positioned on the center line of resistance to compression muscle corresponding to it.
Described radiating sleeve and armouring overlap and all adopt copper material to make.
Described heat radiation is protruding relative with the position of heat conduction projection, and itself and radiating sleeve are integral type structure.
Adopt after said structure, the utility model compared to the prior art advantageously: structure of the present utility model is simple, and the heat radiation projection on radiating sleeve can play good radiating effect with heat conduction projection, the heat produced when can be vaporized cable core work fast; Armouring cover has preferably intensity, and it effectively can reduce or remit the extruding force of outer bound pair cable core, prevents cable core generation cracking phenomena, extends its useful life; In resistance to compression, pipe can share the extruding force of cable core to insulation inner sleeve, prevents insulation inner sleeve from because of stressed too concentrating, central part is ftractureed.
