Abstract
The invention relates to a branch cable and relative connector, wherein it comprises that: first preparing cable that uses high-voltage preparation to shape the cable corn, to make its outer diameter error under +/- 0.03mm; the insulated layer is polyethylene; the sheath is made from PVC elastic element; the sheath is extruded and shaped via plastic extruder; the cable outer diameter error is controlled under +/- 0.05mm; the cable connector comprise line groove plate, arc plate and connector; the line groove plate has main cable groove and branch cable groove; the grooves are connected via arc plate; the arc plate and the cable corn are concentric with same diameters; when the cable is connected, the upper and lower opposite connectors are fixed via bolts, to improve reliability, without damaging cable; and the branch position can be changed freely.
Description
Technical field
The invention belongs to the cable technology field, relate to a kind of branch cable that is specifically designed to the street lamp power supply, road lamp power supply system.
Background technology
At present, in the street lamp work progress owing to mostly use common power cable, when making branch line, there is following problem, 1, when making branch line, oversheath, the insulating barrier of cable to be destroyed, after connecting, again cable is recovered, the time of such joint probably needs 1 to 2 hours, and repairs very difficult assurance of electrical property of back cable.2, adopt fan line core because common cable is most of, and the contact point of known T binding clip is with circular distribution, so contact point might be unreliable when using the T binding clip.3, present known pre-branched cable is processing typing in advance in factory, and breakout sometimes has interim change at the construction field (site), and the first dawn moulding of pre-branch just can't change, so do not adopt pre-branched cable substantially in the street lamp construction.
Summary of the invention
It is unreliable that the present invention mainly solves the electrical property after the joint time, long and common power cable connector recovered of branch line in street lamp and building cable construction process, and pre-branched cable is problem such as dumb in street lamp is constructed.
The technical solution adopted for the present invention to solve the technical problems is:
Situation according to specification, model and the cross section of the electric wire and cable of design department design, we at first prepare cable, the method that leader cable 1 adopts high pressure to prepare cable is carried out drawing-die to cable core and is pressed typing, its external diameter error is guaranteed in positive and negative 0.03 millimeter of standard value, insulating barrier adopts polyethylene, restrictive coating adopts the PVC elastomer, to cable cover(ing) plastic extruder extrusion modling, outside diameter of cable tolerance is controlled in positive and negative 0.05 millimeter of standard value.
According to required cable, the preparation cable connector, cable connector comprises wire casing plate, swing link and jockey, the wire casing plate is provided with leader cable groove and branch cable groove, is connected with swing link between wire casing, and said swing link is meant the crescent shape at the position of wire casing upper process, just in time fit with cable, swing link and cable core should be the same diameters of concentric, after cable is worn the people, corresponding up and down jockey are fixed with fastening bolt.
With wire casing plate, swing link and clamp nut injection molding machine single injection-molded.Swing link is arranged in pairs in the both sides of bolt, and the intensity that guarantees contact point is with stable.
Swing link adopts copper to cross the material of silver.
The connector end of branch cable is shut with pyrocondensation cable end socket and is prevented to make moist into water.
The invention has the beneficial effects as follows: can improve the reliability of joint efficiency and joint, not need cable is destroyed to guarantee the electrical property of cable.Cable branch is finished maneuverability at the scene can change branch location at any time according to field condition.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
Situation according to specification, model and the cross section of the electric wire and cable of design department design, we at first prepare cable, adopt method that high pressure prepares cable that leader cable core 9 and branch cable core 12 are carried out drawing-die and press typing, its external diameter error is guaranteed in positive and negative 0.03 millimeter of standard value, main push-towing rope insulating barrier 10 adopts polyethylene, main push-towing rope restrictive coating 11 adopts the PVC elastomer, to cable cover(ing) plastic extruder extrusion modling, outside diameter of cable tolerance is controlled in positive and negative 0.05 millimeter of standard value.Branch cable core 12 adopts common copper wire, require copper wire external diameter tolerance positive and negative 0.01 millimeter in standard value, branch cable insulating barrier 13 adopts the PVC elastomers to utilize the plastic extruder extrusion modling, outside diameter of cable tolerance is controlled in positive and negative 0.05 millimeter of standard value.Branch cable is used pyrocondensation cable end socket 4 and is shut the prevention into water that makes moist before installation.
According to required cable, preparation cable connector 3, connector is identical two parts up and down, each part all is to comprise the wire casing plate, swing link and connecting hole, the wire casing plate is provided with leader cable groove and branch cable groove, between wire casing, be connected with four swing links 5,6,7,8, the swing link both sides the crescent shape of the position of wire casing upper process just in time with leader cable 1 and branch cable 2 interlocks, swing link and cable core should be the same diameters of concentric, between two wire casings, be provided with bolt hole, with the wire casing plate, swing link injection molding machine single injection-molded, after cable is worn the people, that corresponding up and down jockey is fixing with fastening bolt 14.
Swing link adopts copper to cross the material of silver.
The present invention can reach instructions for use fully through test of many times, to possess production capacity.
Branch cable provided by the invention and connector, be described by embodiment, person skilled obviously can be changed or suitably change and combination content as herein described in not breaking away from content of the present invention, spirit and scope, realizes technology of the present invention.Special needs to be pointed out is, the replacement that all are similar and change apparent to those skilled in the artly, they are regarded as being included in the utility model spirit, scope and the content.
