Brief description of the drawings
Fig. 1 is the structural representation of the utility model cable cover(ing) the first embodiment;
Fig. 2 is the structural representation that in the utility model cable cover(ing) the first embodiment, cable cover(ing) is combined with cable.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See figures.1.and.2, show respectively the structural representation of the utility model cable cover(ing) the first embodiment and the structural representation that cable cover(ing) is combined with cable, wherein the part in Fig. 2 is cross sectional representation.
In the present embodiment, this cable cover(ing) 10 is the cylinder by injection molding two connections of silastic material, wherein these two cylindrical thickness the thickness of this cable cover(ing) can be 5mm-7mm.
Select silastic material be because it has high resiliency, anti-tearly pulls, high temperature resistant, aging-resistant characteristic and good flame-retarding characteristic.Wherein, because high resiliency, the high radial convergent force of this material can make the combination between water-proof jacket and cable tightr, better to protect cable intermediate joint to avoid the harm such as humidity, water logging; Because this material anti-tear pulls, the characteristic such as high temperature resistant, anti-aging, can make this water-proof jacket longer service life, do not need frequent replacing, further save cost; Due to the good flame-retarding characteristic of this material; even if can further ensure that the situations such as Mars appear in water-proof jacket inside; also can extinguish because of anoxic; when cable is played to better protective effect, also can effectively avoid therefore cable generation security incident and impact and harm on its environment of peripheral cable.
In the cylinder of two connections, comprise the first cylinder 11 for wrapping up unit cable and for wrapping up the second cylinder 12 of unit cable, and the first cylinder 11 is connected by the conical surface 13 with the second cylinder 12.
That is to say, this cable cover(ing) is split-phase type absolute construction, and each cable cover(ing) is used for protecting a cable, with respect to prior art, can avoid damaging due to cable sheath the generation of the situations such as the alternate mutual infiltration of the cable causing, interference.
Wherein, the internal diameter of the first cylinder 11 is greater than the internal diameter of the second cylinder 12, preferred, according to conventional cable dimension, can be set to 36mm-40mm by the first cylindrical internal diameter, and the second cylindrical internal diameter is set to 32mm-35mm.The cable cover(ing) of this reducing type, not only, applicable to same cable and two cables that external diameter is identical being connected, also, applicable to two cables that external diameter is not identical that are connected, applicability is stronger.
Further; the length of cable cover(ing) is set to 380mm-450mm; to ensure that this cable cover(ing) has long as far as possible guard space; also can not cause being not easy to because the length of cable cover(ing) is long installing simultaneously; according to actual needs, can preferably the length of cable cover(ing) can be arranged to 400mm.
Wherein, for adapting to different needs, it is identical that length that can the first cylinder 11 and the length of the second cylinder 12 are set to, and length that also can the first cylinder 11 is set to different from the length of the second cylinder 12.
In the present embodiment, also can on cable cover(ing), be provided with ruggedized construction, this ruggedized construction can make the laminating degree between cable cover(ing) and the unit cable of its parcel tightr, so that the better tightness of cable cover(ing).
This ruggedized construction can comprise be arranged on the first cylinder 11 and be away from second cylinder 12 one end ring-type reinforcement 111 and/or be arranged on the second cylinder 12 and be away from the reinforcement 121 of the ring-type of first cylinder 11 one end.
That is to say, according to actual needs, can only on the first cylinder 11, reinforcement 111 be set, also can only on the second cylinder 12, reinforcement 121 be set, also can on the first cylinder 11 and the second cylinder 12, reinforcement 111,112 be set simultaneously, better to ensure before this cable cover(ing) is mounted, while expanding this cable cover(ing) with supporting tool, greatly reduce the possibility of this cable cover(ing) from end face cracking.
Further, this ruggedized construction also comprises and is sheathed on the locking steel band 112 on the first cylinder 11 and/or is sheathed on the locking steel band 122 on the second cylinder 12.
That is to say, according to actual needs, locking steel band 112 can be only set on the first cylinder 11, locking steel band 122 also can be only set on the second cylinder 12, locking steel band 112,122 also can be set simultaneously on the first cylinder 11 and the second cylinder 12, to strengthen the laminating degree of cable cover(ing) and cable, wrap cable 20 with what further ensure that cable cover(ing) can be tight and fixing, and then ensure that this cable cover(ing) can not be shifted, have better sealing, reduce the possibility of cable water inlet, the situation such as destroyed.
In the time that reality is used, can use the supporting tool (such as stay pipe etc.) of drawing out type that the cable cover(ing) of the present embodiment is expanded in advance, cable cover(ing) after expansion is set in to the pre-position on cable, then pump supporting tool, this cable cover(ing) utilizes the radial contraction power of himself to form tight being coated to cable, this cable cover(ing) can be on cable installing one by one, also install in the precalculated position on cable as required, and then effectively avoid because of cable bad, make moist, the situations such as water inlet and the generation of the security incident that causes, and due to the cable cover(ing) that this cable cover(ing) is reducing type, therefore, applicable to the cable of various outer diameter, applicability is stronger.
In addition, owing to being arranged at the ruggedized construction (namely reinforcement, locking steel band etc.) at these cable cover(ing) two ends, can make this cable cover(ing) more difficult cracking in the time being expanded, and the two ends of cable cover(ing) can be tightr and fixing wrap cable, ensure that this cable cover(ing) has better sealing, and then effectively prevent because of cable bad, make moist, security incident that water inlet etc. causes, and, due to the good sealing of this cable cover(ing) and anti-flammability, also can effectively impel just in case when cable generation combustion phenomena, this burning is extinguished fast because of anoxic.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; any people who is familiar with this technology is in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
