Abstract
The utility model relates to a cable traction tool and particularly relates to a novel three-core cable waterproof traction head, which comprises a traction cap. The interior of the traction cap is connected with crimping pipes through a connecting plate. The crimping pipes are in compression joint with a plurality of conductors respectively. The traction head is characterized in that the outside of each crimping pipe is sleeved with a thermal plastic pipe. The outside of the thermal plastic pipe is sleeved with a thermal plastic pipe finger stall. The connection part of each crimping pipe with the tail end of each conductor is lapped with an adhesive tape and a belt sheath layer. The novel three-core waterproof traction head has the advantages of good waterproof performance, high tensile strength, long service life, simple structure, convenient use and the like.
Description
Technical field
The utility model relates to a kind of cable pulling frock, especially relates to a kind of novel three-core cable waterproof drawing head.
Background technology
As everyone knows, three core cable tracting head is comprised of aluminium hydraulic pressed connecting pipe, thermoplastic tube, connecting plate and traction cap at present, aluminium hydraulic pressed connecting pipe is crimped on the conductor thread core, outside aluminium hydraulic pressed connecting pipe, put again a thermoplastic tube, after thermoplastic device warming thermal plastic is good, load onto connecting plate at the aluminium hydraulic pressed connecting pipe front end, put traction cap and install filler, put outside at last a thermoplastic tube.The defective of conventional art and deficiency: in use, the aluminium hydraulic pressed connecting pipe nexine is smooth, and thermoplastic tube only is set to outside the copper screen, when pulling force all easily disconnects during greater than resistance, causes into water.
Summary of the invention
The utility model mainly is for the existing above-mentioned technical problem of prior art, provides that a kind of water resistance is good, tensile strength is high, long service life, novel three core waterproof drawing heads simple in structure, easy to use.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of novel three core waterproof drawing heads, comprise traction cap, link to each other with aluminium hydraulic pressed connecting pipe by connecting plate in the traction cap, aluminium hydraulic pressed connecting pipe is crimped on respectively on the many conductors, it is characterized in that described aluminium hydraulic pressed connecting pipe skin is arranged with thermoplastic tube, described thermoplastic tube is arranged with the thermoplastic tube fingerstall outward, and described aluminium hydraulic pressed connecting pipe and conductor ends junction are surrounded with adhesive tape and band restrictive coating.The utility model is on original cable drawing head basis aluminium hydraulic pressed connecting pipe to be transformed the frictional force that increases conductor and aluminium hydraulic pressed connecting pipe; And outside thermoplastic tube, put again a thermoplastic tube fingerstall, increase the tensile strength of thermoplastic tube.
As preferably, described aluminium hydraulic pressed connecting pipe inboard is provided with internal thread.Be arranged to tiny shape of threads at the aluminium hydraulic pressed connecting pipe nexine, increased the frictional force with conductor, resistance to tension is strong.
As preferably, described conductor ends is provided with tape insulation and armour.Simple in structure, easy to use.
As preferably, described traction cap skin is arranged with thermoplastic tube.Thermoplastic is effective, long service life.
As preferably, described adhesive tape is adhesive waterproof tape.Mackintosh on wrapped on the conductor thread core that exposes in aluminium hydraulic pressed connecting pipe and insulated wire cores, water resistance is good.
As preferably, be bolted between described connecting plate and the traction cap.Simple in structure, be connected firmly, practical.
As preferably, described number of conductors is three.The utility model is three core waterproof drawing heads.
Therefore, the utlity model has that water resistance is good, tensile strength is high, long service life, the characteristics such as simple in structure, easy to use.
