Abstract
The invention discloses a cable intermediate joint, which comprises an outer sheath, PVC tapes, waterproof tapes and more than one joint pipe, wherein the joint pipes are arranged in the outer sheath; the PVC tapes and the waterproof tapes are sequentially wound on the joint pipes; a ground wire is arranged at the lower part of each joint pipe; each joint pipe is provided with a semiconducting layer and a woven copper mesh; each semiconducting layer and each the joint pipe are in glued connection; an insulating sleeve and a conductor connecting pipe are arranged in each joint pipe; each insulating sleeve is electrically connected with each conductor connecting pipe; a steel armor and an inner sheath are also arranged in each waterproof tape; and each inner sheath and each conductor connecting pipe are in glued connection. The cable intermediate joint is high in tensile strength, track-resistant, corrosion-resistant, convenient to mount and reliable to ground.
Description
Technical field
The present invention relates to a kind of cable intermediate 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, when laying wires, does not often 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.
Current existing cable joint complex structure, install inconvenient, structural strength is lower, easily damages.
Summary of the invention
It is high that the technical problem to be solved in the present invention is to provide a kind of this resistance to spalling anti-, and anti-electric-mark is corrosion-resistant, easy for installation, the reliable cable intermediate joint of ground connection.
For solving the problem, the present invention adopts following technical scheme: a kind of cable intermediate joint, comprise oversheath, PVC is with, water blocking tape and junction block, described junction block is located in oversheath, described PVC band and water blocking tape are wrapped on junction block successively, ground wire is provided with below described junction block, the semi-conductive layer arranged can keep Electric Field Distribution even, braiding copper mesh can have shielding action, anti-electric-mark simultaneously, PVC band and water blocking tape can have good waterproof effect by holding structure, corrosion-resistant, easy for installation, steel armour and inner sheath can keep this resistance to spalling anti-high, ground wire can keep ground connection reliable, described junction block is provided with more than one, described junction block is provided with semi-conductive layer and braiding copper mesh, described semi-conductive layer glues together with junction block and is connected, insulating case and conductor connecting tube is provided with in described junction block, described insulating case and conductor connecting tube are electrically connected, steel armour and inner sheath is also provided with in described water blocking tape, described inner sheath glues together with conductor connecting tube and is connected.
As preferably, described oversheath diameter, at more than 40mm, can keep cable capacity large.
As preferably, outside described junction block, be also wound with constant force spring, keep Stability Analysis of Structures between junction block.
As preferably, described conductor connecting tube diameter, at more than 10mm, keeps conductor to connect compact.
As preferably, described PVC tape thickness is 1.5mm, and holding structure has good toughness.
Beneficial effect of the present invention is: the semi-conductive layer of setting can keep Electric Field Distribution even, braiding copper mesh can have shielding action, anti-electric-mark simultaneously, PVC band and water blocking tape can have good waterproof effect by holding structure, corrosion-resistant, easy for installation, steel armour and inner sheath can keep this resistance to spalling anti-high, and ground wire can keep ground connection reliable.
