The cable body 1 sequentially comprises an outer sheath 1.1, an armor layer 1.2, an outer corrosion-resistant layer 1.3, a shielding layer 1.4 and a water blocking layer 1.5 from outside to inside, a plurality of cable core units 2 are arranged in the water blocking layer 1.5, and the cable core units 2 sequentially comprise an inner corrosion-resistant layer 2.1, a flame-retardant layer 2.2, an insulating layer 2.3 and a conductor 2.4 from outside to inside; the outer sheath 1.4 is a polytetrafluoroethylene outer sheath; the armor layer 1.2 is a steel wire armor layer; the outer corrosion-resistant layer 1.3 is a chlorosulfonated polyethylene rubber layer or a polyester material layer; the inner corrosion-resistant layer 2.1 is a chlorosulfonated polyethylene rubber layer or a polyester material layer; the shielding layer 1.4 is a copper wire braided shielding layer; the waterproof layer 1.5 is a waterproof winding belt layer; the flame-retardant layer 2.2 is a low-smoke halogen-free flame-retardant layer; the insulating layer 2.3 is a silicon rubber insulating layer, and the conductor 2.4 is a copper conductor.
As shown in the drawings, the cable of the present application has advantages of the cable of embodiment 1, and further increases the communication capability by integrating a plurality of cable bodies together to realize communication between more devices. And because under the service environment of naval vessel, the cable has the possibility of rocking, so the cable of this application has set up fixing device, thereby through first bunch of cable unit, two second bunch of cable units and protection tube unit realization to the cable gather a bundle and fixed, solved cable body in particular and gathered a bundle and fixed under the condition that needs buckle to realize stable use and fixed mounting of cable. The mode of installation is, can place the cable body in the first cable recess of putting of first support skeleton and the second of second support skeleton puts the cable recess in to insert from the side of first support skeleton first enclosure unit, thereby the side of second support skeleton inserts second enclosure unit, realizes restrainting the fixed between the cable unit to cable body, first bundle of cable unit and second. In addition, as shown in fig. 9 to 10, after the cable body and the second enclosure unit are installed, the pressing block may be driven by the driving screw rod to move in a direction away from the second central passage, so as to urge the second separation gap of the second support unit to become larger, but at this time, because the second enclosure unit and the fixing sleeve are outside the second support framework, the expansion of the second separation gap of the second support framework, which becomes larger, may cause the second support framework, the cable body and the second enclosure unit to completely abut against each other. The drive of lead screw utilizes the instrument to accomplish through maintainer, after the operation of rotatory lead screw, installs the protection tube unit after that, and the spacing post of protection tube unit this moment just inserts in driving the recess to prevent the unexpected rotation of driving the recess.
In addition, install the shutoff unit between first bundle of cable unit and two second bundles of cable units, on the one hand to first, the uncovered of two central channels seals, mutual interference when avoiding measuring the temperature, on the other hand makes, relative position between first bundle of cable unit and two second bundles of cable units is fixed completely (the shutoff unit first, two elasticity butt joint piece are extrudeed slightly and are produced elastic deformation, thereby the position of shutoff unit is motionless), the tip closing plate at second bundle of cable unit both ends also plays the effect of shutoff second central channel open end in addition, thereby avoid the foreign matter to get into second central channel on the one hand, on the one hand makes the temperature measurement of second central channel more accurate. When detecting the temperature, stretch into the jack of block rubber through the measuring head with temperature-detecting device to the realization inserts from inserting the end of Y shape measurement channel through the measuring head with temperature sensor (preferred measuring head can take bending function), through the intercommunicating pore, passes through the side opening again, thereby realizes the detection to temperature in the first center channel, judges whether cable work is normal through two temperature sensor's measured value. In addition, the two insertion ends of the Y-shaped measuring channel are arranged, so that the first protection tube can be installed in different directions, one insertion end can be plugged, the other insertion end is used, the used insertion end is ensured not to face upwards, and liquid and the like are prevented from entering the protection tube unit. In addition, the measuring head can be inserted into the side hole, the position of the first cable bundling unit is also checked to be accurate, if looseness is generated between the first cable bundling unit and the second cable bundling unit and the cable body, the cable body is dragged at the first cable bundling unit and the second cable bundling unit, two plugging units can be dropped, and therefore position deviation of the first cable bundling unit can be generated, and the measuring head cannot be continuously inserted into the measuring hole through the communicating hole after being inserted into the Y-shaped measuring channel. Therefore, the detection is on one hand the detection of the temperature, the judgment of whether the temperature is abnormal or not, the fixing of the cable body is loosened or not, and the detection of whether the position of the first cable bundling unit is cheap or not.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
