Abstract
The utility model discloses an armored multi-core branch cable comprising a main cable and a plurality of branch cables connected with the main cable, and the connection position is injected into a branch connecting body, wherein the main cable comprises a main cable conductor, and main cable insulation, a main cable armored layer and a main cable sheath are arranged outside the main cable conductor; each branch cable comprises a branch cable conductor, and branch cable insulation, a branch cable armored layer and a branch cable sheath are arranged outside the branch cable conductor; the main cable conductor and the branch cable conductor are connected by using a clamp; the main cable insulation, the main cable armored layer and the main cable sheath are peeled off to form a front and a rear sections at the clamping connection position; and metal conducting wires which are insulating are welded between the main cable armored layers of the front and the rear sections as well as between the branch cable armored layer and the main armored layer. The metal conducting wires which are insulating are adopted between the armored layers for welding so that the volume of the branch connecting body is greatly reduced, and the processing procedures are reduced compared with that in the prior art.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of armouring multi-core branch cable.
Background technology
Branch cable is because have advantages such as power supply safety is reliable, use cost is low, installation is simple, environmental requirement is low, non-maintaining, obtained promoting widely and using, be widely used in distribution systems such as dwelling house, office tower, tunnel, hotel, hospital, market, also can be used for illuminator such as street lamp power supply, road lamp power supply, highway, bridge, tunnel and airfield runway etc. that backbone has the branch line requirement.Therefore existing branch cable seldom adopts sheathed structure because armour can't keep continuously and processing difficulties.
Chinese invention patent 200910155255.4 discloses a kind of armouring multi-core branch cable, be injection molded into branch's connected body after earlier being crimped on leader cable and branch cable conductor together, armour with leader cable, branch cable, connected body welds together again, at last injection moulding branch connected body once more.Though this armouring multi-core branch cable armour has carried out effective connection, continuity and integrality have been kept, but the branch's connected body volume and weight through twice injection moulding is all bigger, influence attractive in appearance, packing, installation are extremely inconvenient, have also taken wiring space, and procedure of processing is loaded down with trivial details simultaneously, welding and also must wait for for the second time the injection moulding first time during injection moulding connected body after connected body can carry out after cooling off fully, the cycle of processing is also longer.
The utility model content
Technical problem to be solved in the utility model provides a kind of easy to process, the armouring multi-core branch cable that takes up room little.
Armouring multi-core branch cable described in the utility model, comprise leader cable and some branch cables that are connected leader cable, the junction is injection molded into branch's connected body, described leader cable comprises the leader cable conductor, sets gradually leader cable insulation, leader cable armour and leader cable sheath outside the leader cable conductor; Every branch cable comprises the branch cable conductor, the branch cable insulation, branch cable armour and the branch cable sheath that set gradually outside the branch cable conductor; Adopt anchor clamps to connect between leader cable conductor and the branch cable conductor; In the anchor clamps junction, two-section before and after leader cable insulation, leader cable armour and leader cable sheath are stripped from and are formed; Welding the plain conductor that has insulation between the leader cable armour of front and back two-section and between branch cable armour and the leader cable armour.
Improvement of the present utility model is after leader cable and the crimping of branch cable conductor, with adopting the plain conductor that has insulation to weld between the front and back two-section armour of leader cable and between branch cable armour and the leader cable armour, be injection molded into branch's connected body at last again.The volume of branch's connected body can significantly dwindle like this, and the relative prior art of procedure of processing has also reduced.Armour adopts the plain conductor have insulation to weld the armour of leader cable and branch cable is linked together, and armour can effective grounding.For helping processing and fabricating, the plain conductor that has insulation is advisable with metallic copper core annealed copper wire especially.For the contact resistance that guarantees the welding position reaches requirement, especially with 4 ~ 10mm
2The metallic copper heart yearn is advisable.The plain conductor that has insulation that connects can be one or more.Though branch's connected body does not install armour additional, because branch connected body present position generally is in switching place of installing, and also connected body employing injection moulding mode, thickness is thick than extrusion molding, and integral body also has load-carrying properties preferably, can satisfy the armouring requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, armouring multi-core branch cable of the present utility model, comprise leader cable and the multicore branch cable that is connected leader cable, the junction is injection molded into branch's connected body 12, described leader cable comprises leader cable conductor 4, sets gradually leader cable insulation 3, leader cable armour 2 and leader cable sheath 1 outside the leader cable conductor; Every branch cable comprises branch cable conductor 5, the branch cable insulation 6, branch cable armour 7 and the branch cable sheath 8 that set gradually outside the branch cable conductor; Adopt anchor clamps 9 to connect between leader cable conductor 3 and the branch cable conductor 5; In anchor clamps 9 junctions, two-section before and after the insulation of leader cable, armour and sheath are stripped from and are formed, in anchor clamps 9 junctions, two-section before and after leader cable insulation, leader cable armour and leader cable sheath are stripped from and are formed; Welding the plain conductor 11 that has insulation 10 between the leader cable armour of front and back two-section and between branch cable armour 7 and the leader cable armour 2.
The utility model provides a kind of thinking and implementation method of armouring multi-core branch cable; concrete application approach is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
