Abstract
The invention discloses a cable joint. The cable joint comprises a sleeve, a T-shaped plug, a back end cap and a stress cone, wherein the sleeve is arranged at a front end of the T-shaped plug; the sleeve is in threaded connection with the T-shaped plug; a stud is embedded into the T-shaped plug; the T-shaped plug is fixedly connected with the back end cap through the stud; the stud is provided with a flat washer, a spring washer and a nut; the nut is in threaded connection with the stud through the flat washer and the spring washer; the stress cone is arranged at the bottom of the T-shaped plug; the stress cone is connected with the T-shaped plug in a clamping way; a lug is arranged in the stress cone; and one side of the T-shaped plug is provided with a ground wire hole. The cable joint has the advantages of good insulating effect, high sealing performance and high structural stability.
Description
Technical field
The present invention relates to a kind of cable joint.
Background technology
Cable joint is also known as cable end, after cable laying is good, in order to become a continuous print circuit, each section of line must connect as a whole, these tie points are just called cable joint, the cable joint of cable line middle part is called transition joint, and the cable joint of circuit two end is called terminals, cable joint is used to locking and fixing line, play the effect of water proof and dust proof against shock, its Main Function makes circuit unobstructed, cable is made to keep sealing, and ensure the class of insulation at cable joint place, it is made to run safely and reliably, if poor sealing, not only can leakage of oil oil-paper be caused to dry up, and moisture also can invade cable inside, make paper insulation hydraulic performance decline, some electrical install workmen is when laying wires, often do not note installing, should with insulating sleeve place not tubing, also terminal box should not be filled with the place of terminal box, not even adopt hinge joint method in power lug place, but adopt hook solid method of attachment violating the regulations, the contact resistance of this hook solid method of attachment is very large, constantly generate heat during energising, neighbouring plank can be made progressively dry, charing, finally burn, cause fire, power lug heating not only can cause a large amount of energy losses, and the normal work of electric equipment can be had a strong impact on, light then in circuit operating current increase, the electric equipment lost of life, heavy then the production of well afoot can have been interrupted suddenly, scientific research, medical operating and other activity, also fire and electric shock accidents etc. can be led to, cause loss difficult to the appraisal.
The process outer semiconductor shielding of outer semiconductor shielding is the semiconductive material that cable and cable joint insulating exterior play uniform electric field effect, the same with interior shield semiconductors, very important effect is served in cable and joint, outer semiconductor port must also require to seamlessly transit with insulation by straight uniform, and increases to shield to overlap around semiconductor tape and cable body outer semiconductor at cable joint and be communicated with.
Current existing cable joint complex structure, install inconvenient, structural strength is lower, and sealing effectiveness is bad, easily aging.
Summary of the invention
It is good that the technical problem to be solved in the present invention is to provide a kind of insulation effect, and closed performance is good, the cable joint that structural stability is high.
For solving the problem, the present invention adopts following technical scheme: a kind of cable joint, comprise sleeve pipe, T-shaped plug, rear plug and stress cone, described sleeve pipe is located at T-shaped plug head, described sleeve pipe is threaded with T-shaped plug, stud is provided with in described T-shaped plug, described T-shaped plug is fixedly connected with rear plug by stud, described stud is provided with plain washer, spring washer and nut, the T-shaped plug arranged keeps easy for installation, compact conformation, good sealing effect, stud can retaining sleeve and rear plug to install stability high, plain washer and spring washer can retention nut firmly be fixed on stud, prevent landing, line ear keeps conductive effect good, ground connection string holes conveniently accesses ground wire, described nut is connected with stud bolt thread with spring washer by plain washer, described stress cone is located at bottom T-shaped plug, described stress cone holds with T-shaped plug and is connected, in described stress cone, wired ear is set, described T-shaped plug side is provided with ground connection string holes.
As preferably, described rear plug side is provided with protective cover, and holding structure is firm, good airproof performance.
As preferably, described rear plug is fixedly connected with protective cover, keeps installing firmly.
As preferably, described line ear outer felt is wound with semi-conductive tape, joint internal electric field can be kept to be evenly distributed, improve electric field.
As preferably, described semi-conductive tape thickness is 5mm, keeps good shield effectiveness, improves electric field.
Beneficial effect of the present invention is: the T-shaped plug of setting keeps easy for installation, compact conformation, good sealing effect, stud can retaining sleeve and rear plug to install stability high, plain washer and spring washer can retention nut firmly be fixed on stud, prevent landing, line ear keeps conductive effect good, and ground connection string holes conveniently accesses ground wire.
