Abstract
The utility model relates to a drawing head for laying a three-core cable. The drawing head comprises a traction sealing cap, a fixed circular plate and three conductor crimping pipes, wherein the traction sealing cap comprises a hoisting ring and a traction cover; the hoisting ring is fixedly connected with the traction cover; an inner thread hole of the traction cover is arranged at the wall of an inner cavity; three connecting holes are arranged on the fixed circular plate; an outer thread of the fixed circular plate matched with the inner thread hole of the traction cover is arranged on the outer lateral wall of the fixed circular plate; the outer threads of the conductor crimping pipes are arranged at the front ends of the conductor crimping pipes; cylindrical cavities for inserting a conductor are arranged at the rear ends of the conductor crimping pipes; the front ends of the three conductor crimping pipes are respectively inserted into the three connecting holes and respectively locked on the fixed circular plate through three nuts, and the fixed circular plate is locked inside the inner cavity of the traction cover through the outer thread of the fixed circular plate and the inner thread hole of the traction cover. Compared with the prior art, the drawing head has the advantages and effects of being simple in structure, convenient to process and install, high in strength, and good in waterproof sealing effect.
Description
Technical field
The utility model relates to a kind of three-core cable laying drawing head.
Background technology
Cable can adopt various ways to carry out laying installation now, but which kind of mounting means all needs a tractive effort, if this power directly is added on the cable, can cause irreversible destruction to cable insulation.The drawing heads that adopt draw cable more in existing installation.It is little that the traditional drawing head that uses in the cable installation process at present exists bearing tension, and sealed waterproof effect is poor, processing, installation complexity, the problems such as manufacturing cost height.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, processing, easy for installation, and intensity is high, the good three-core cable laying drawing head of waterproof sealing effect.
The technical scheme in the invention for solving the above technical problem is: this three-core cable laying drawing head, it is characterized in that: comprise the traction sealing cap, fixed disc and three conductor crimping pipes, described traction sealing cap comprises suspension ring and traction cover, suspension ring are fixedly connected with the traction cover, described traction cover offers the inner chamber that supplies fixed disc and conductor crimping pipe to stretch into, be provided with traction cover internal thread hole on the wall of described inner chamber, offer three connecting hole at fixed disc, be provided with and draw the fixed disc external screw thread that the cover internal thread hole matches on the lateral wall of described fixed disc, the front end of described conductor crimping pipe is provided with conductor crimping pipe external screw thread, the rear end of conductor crimping pipe is provided with the cylindrical cavity that inserts for conductor, the front end of three conductor crimping pipes inserts respectively three connecting hole, and passing through respectively three nut checks on fixed disc, fixed disc is locked at by fixed disc external screw thread and traction cover internal thread hole and draws in the inner chamber that covers.
Operation principle of the present utility model: the cylindrical cavity that at first conductor of cable is inserted the conductor crimping pipe, then crimping, after conductor is compacted, between conductor and conductor crimping pipe, adopt the heat shrinking sleeve seal of tube, then the front end of three conductor crimping pipes is inserted respectively three connecting hole, and pass through respectively three nut checks on fixed disc, will draw at last sealing cap and be tightened on the fixed disc according to hand of spiral, and with the heat-shrinkable T bush sealing, finish to install.
Suspension ring described in the utility model and traction cover are the integral type structure.
The center of circle of connecting hole described in the utility model three be evenly distributed on the concentric circle of fixed disc on.
The utility model compared with prior art has the following advantages and effect: simple in structure, and processing, easy for installation, intensity is high, and waterproof sealing effect is good.
