Abstract
A kind of compression joint type street lamp water joint box, it is the C shaped cable clamp utilizing high conduction performance, under the prerequisite not cutting off main cable, main cable heart yearn is contacted heart yearn joint with the electric conductor of branch cable heart yearn by the face that hydraulic tongs crimps, connector box is force fast-turn-off type, is made up of impact-resistant transparent polypropylene plastics, and the terminal box that volume ratio is traditional is small and exquisite, encapsulating amount decreases 50%, and cost reduces 50%.The utility model is used in the various illuminating engineerings such as high ferro, highway, municipal administration, view, can 100% guarantee supply line's safe operation, and non-maintaining.
Description
Technical field
The conduction of electric equipment and electrical engineering connects and connection device.
Background technology
So far, in municipal administration, view, the buried waterproof junction box used in street lighting engineering, the heart yearn branch connection of cable all adopts insulation puncture line clamping connected mode, because insulation puncture line clamping volume is large, the design volume of this terminal box is also large, and the contact area of insulation puncture line clamping connected mode is little, the power supply trouble of as easy as rolling off a log generation bad connection, the utility model compression joint type waterproof streetlamp connector box is then adopt compression joint type C shaped cable clamp to carry out the connection of cable core branch, contact-making surface is face contact, stop loose contact, safe and reliable, reduce the volume of terminal box, decrease the fluid sealant consumption of 50%, reduce cost.
Summary of the invention
The utility model compression joint type street lamp connector box technical problem to be solved is: 1, the branch of cable core to connect contact area large, fault-free, non-maintaining, the constant unification of crimp quality; 2, connector box compact, water-tight.
The connection of street lamp power supply, road lamp power supply system main cable and branch cable carries out under the prerequisite not disconnecting main cable, and C shaped cable clamp can meet the technical requirement of continuation method under this prerequisite.The branch of cable core connects the position being achieved in that and settling C shaped cable clamp at main cable heart yearn, first insulating barrier is peelled off the length identical with C shaped cable clamp length, and same length is also peelled off in branch cable heart yearn end, expose their metallic conductor; First main cable cored wire conductor is embedded wherein from C shaped cable clamp indentation, there, insert branch cable cored wire conductor again, then use 12 tons of hydraulic tongses to be crimped in the lump with main cable cored wire conductor and branch cable cored wire conductor by C shaped cable clamp, after having crimped, just become heart yearn joint.The pressure that every core assembly wire terminal is applied in is unified, and main, the branch line face of continuing is face contact, and conduction is reliable, and quality is unified.Note, the C shaped cable clamp in connector box is settled and will be staggered in order, and after heart yearn coupling compression joint completes, with PVC insulating tape parcel, insulation is reliable.
The sealing of the utility model connector box is achieved in that connector box is the container that upper and lower two housings fasten; Junction, connector box both sides is serpentine hermetically-sealed construction; The seal groove holding shutoff foam is had on connector box both sides, at the position of master corresponding to seal groove, branch cable, shutoff foam is wrapped on cable, again at upper and lower casing around connecting in the ridge process of closing up, in shutoff foam embedding sealing groove, buckle buckle, the manhole appendix of cable, by shutoff, forms a closed chamber in connector box; Treat fluid sealant to pour into connector box from glue filling opening, after observing glue spilling from steam vent, by glue filling opening and vent cap, underground can be imbedded, moistureproof and waterproof, fault-free, non-maintaining.
The street lamp waterproof junction box that traditional street lighting service cable circuit uses, generally adopt insulation puncture line clamping connected mode, can not only there is the defect that intrinsic contact point is little by insulation puncture line clamping, and when the heart yearn of main cable be less than 50 squares with lower wire time, main cable heart yearn torsional deformation can be made, make contact point depart from main cable center, affect the safe and reliable of supply line.
The trunk of the utility model compression joint type water joint box, the heart yearn connected mode of branch cable, what adopt is C shaped cable clamp, its volume is less than insulation puncture line clamping, cored wire conductor contact is face contact, and the reliability of conduction can not be affected because of the distortion of main cable, and saved the fluid sealant of half, compared to traditional waterproof junction box, the utility model has very high cost performance and promotion prospect.
