Abstract
The utility model discloses a water proof type branch cable mainly consisting of a main cable, a branch cable and a branch joint connected with the two cables, wherein the main cable and the branch cable structurally comprise a middle conductor as well as an insulating layer and a first water proof tape sequentially wrapped outside the conductor; the branch joint is internally provided with a connecting joint for connecting the conductor of the main cable and the conductor of the branch cable together; and after crimping, the connecting joint is covered round with a second water proof tape at the joint, and lapped with the main cable and the first water proof tape of the branch cable. In the utility model, the branch cable has water proof function without affecting the electric performance thereof.
Description
Technical field
The utility model relates to a kind of power cable, specifically is a kind of waterproofing type branch cable.
Background technology
Branch cable is in system of mesolow of new generation supply line that the electric power system of the middle and later periods nineties is succeeded in developing in the advanced country of a few industry.It has advantages such as power supply safety is reliable, use cost is low, installation is simple, environmental requirement is low, non-maintaining, has therefore obtained promoting widely and using.Can be widely used in distribution systems such as dwelling house, office tower, tunnel, hotel, hospital, market, also can be used for the mobile jib line has the illuminator of branch line requirement (highway, bridge, tunnel and airfield runway).The quality of branch joint has determined the quality of branch cable quality.
The same with common cable, branch cable generally is installed in electric shaft or the cable trough, lays the place and often has more or less moisture inevitably, also tends to be impregnated in the water in the cable trough the inside.Add man-hour and installing and using in the process subsequently at branch cable, also make easily between branch joint and leader cable, the branch cable to produce the slit, thereby cause the infiltration of moisture content.As: the dislocation that the joint connecting piece causes owing to the crimp force effect in compression moulding, use in injection molding insulating material and leader cable, branch cable outer protective sleeve material is inequality and bonding force that cause is poor, in the installation process tractive of leader cable, branch cable is caused that joint is loosening etc.
The intrusion of moisture often cable suffer to destroy, useful life affected main cause.Moisture causes oxidation, the corrosion of conductor from the end of the sheath of cable, cable, invade cable from the branch joint abutting edge, can influence the electrical property of cable, even the abnormal broken line accident takes place.Existing branch cable product leader cable, branch cable do not possess water stop function, and the branch joint place does not carry out any processing that blocks water yet, and has potential safety hazard.
The utility model content
Technical problem to be solved in the utility model provides a kind of branch cable with good water resistance.
A kind of waterproofing type branch cable described in the utility model, it is made up of leader cable, branch cable and the branch joint that is connected aforementioned two cables, the structure of leader cable and branch cable comprises middle conductor and is coated on the conductor outer insulating barrier and first waterstop successively, be provided with the jointing that leader cable conductor and branch cable conductor are linked together in the branch joint, be surrounded with second waterstop after the described jointing crimping in the joint, and overlap with first waterstop of leader cable, branch cable.
Described leader cable and branch cable are single-core cable, and perhaps leader cable is a multicore cable, and branch cable is a single-core cable.Perhaps leader cable is a multicore cable, and branch cable is a multicore cable.
Above-mentioned waterstop, base material are preferably selected the polyester non-woven fabric band for use.Dilatant is natural, semi-natural, also can be for chemical synthesis, as polyacrylate.Described branch cable is preferably selected fire-retardant, low-smoke halogen-free cable for use, and waterstop is fire-retardant waterstop.
The utility model is because after the jointing crimping in branch joint, along wrapped again one deck second waterstop of whole jointing outer surface, first waterstop of this second waterstop and leader cable, branch cable overlaps, so form a complete waterproof system, stop the intrusion of outside moisture, improve the security performance of branch cable greatly, also do not influenced the electrical property of branch cable simultaneously.
Description of drawings
The structural representation of single core branch cable in Fig. 1 the utility model.
The structural representation of multi-core branch cable in Fig. 2 the utility model.
Embodiment
As shown in Figure 1 and Figure 2, waterproofing type branch cable described in the utility model mainly comprises leader cable 1, branch cable 2, branch joint 3, and wherein branch joint 3 is used to connect aforementioned two cables.The structure of leader cable 1 and branch cable 2 comprises middle conductor 4 and is coated on the conductor outer insulating barrier 5 and first waterstop 6 successively, be provided with the jointing 7 that leader cable 1 conductor and branch cable 2 conductors are linked together in the branch joint 3, be surrounded with second waterstop 8 after jointing 7 crimping in the joint, and overlap with first waterstop 6 of leader cable, branch cable.
Above-mentioned waterstop, base material are preferably selected the polyester non-woven fabric band for use.Dilatant is natural, semi-natural, also can be for chemical synthesis, as polyacrylate.Described branch cable is preferably selected fire-retardant, low-smoke halogen-free cable for use, and waterstop is fire-retardant waterstop.Leader cable and branch cable are single core (Fig. 1) or multicore cable (Fig. 2).Be that branch cable can be single core branch cable or multi-core branch cable, multi-core branch cable can also can connect multicore for multicore for multicore order core.
