Abstract
The utility model discloses a kind of cable fixing head belonging to electric wire permanent plant manufacturing technology field.Its structure is: nut is connected with main body by pad, main body is connected with water proof ring, water proof ring is connected with locknut, locknut is tapered structure, skin is provided with spiral, one end of main body is provided with the screw thread matched with nut, and the other end is provided with the clamp jaw matched with water proof ring, correspondingly on water proof ring is provided with groove.Cable fixing head of the present utility model arranges tapered locknut; can available protecting electric wire; prevent locknut end and electric wire friction from losing; when spiral can increase installation and the frictional force of hand or back-up wrench; install easily; whole device all have employed insulating material or insulation system, prevents from producing electric people's accident because of electric leakage.
Description
Technical field
The utility model belongs to electric wire permanent plant manufacturing technology field, is specifically related to a kind ofly can fix many cables and adiabatic cable fixing head.
Background technology
Cable fixing head be widely used in plant equipment electrically, the fixing and protection of the electric wire of marine electrical equipment, corrosion protection equipment; Main Function makes circuit unobstructed; cable is made to keep sealing; and ensure the class of insulation at cable joint place; make it run safely and reliably, prevent hazardous gas from entering instrument or junction box, thus avoid blast; and moisture also can invade cable inside, make paper insulation hydraulic performance decline.
Patent CN103986113 discloses a kind of metallic cable gland, comprises locknut, sealing ring, main body, seal and nut in a tubular form; One end of described main body has the first threaded portion, and the other end has the second threaded portion, has spacing end stand between described first threaded portion and described second threaded portion; One end of described sealing ring is plugged in the inside of described main body, and described locknut coordinates with the first threaded portion of described main body, and described locknut has the pressure section abutted with the other end of described sealing ring; Described seal is socketed between the second threaded portion of described main body and the spacing end stand of described main body, and described nut coordinates with the second threaded portion of described main body.This cable fixing head solves sealing and installs inconvenient problem, but, this cable fixed head can only fix single line cable, if fix two or more than, just there is random line, the problem of twisted wire, in addition, urgent nut easy and cable friction in one end of fixed cable of tubulose, grinds away cable.
In addition, current cable fixing head mostly adopts metal material to make, and heat conductivility is strong, runs into the environment of heat, is easy to transfer heat to electric wire, is fused.
Utility model content
The utility model, for the defect of prior art, proposes a kind ofly can fix many cables and adiabatic cable fixing head.
A kind of cable fixing head, nut 1 is connected with main body 3 by pad 2, and main body 3 is connected with water proof ring 4, and water proof ring 4 is connected with locknut 5;
Described locknut 5 is tapered structure, and skin is provided with spiral 6;
2-4 bar passage 7 is provided with in described water proof ring 4;
One end of described main body 3 is provided with the screw thread matched with nut 1, and the other end is provided with the clamp jaw 8 matched with water proof ring 4, correspondingly on water proof ring 4 is provided with groove 9.
The central authorities of the wall of described main body 3 and locknut 5 are provided with vacuum layer 10, and vacuum layer 10 is filled with filled insulation 11.
The length of described locknut 5 is 1.5-3 times of main body 3 length.
Described pad 2, nut 1 and water proof ring 4 adopt insulating material to make.
The screw thread of described spiral 6 and the inclination angle of horizontal plane are 25-45 °.
The beneficial effects of the utility model: cable fixing head of the present utility model arranges tapered locknut; can available protecting electric wire; prevent locknut end and electric wire friction from losing; when spiral can increase on the one hand installation and the frictional force of hand or back-up wrench; install easily; on the other hand; locknut can be fixed on rope by the oblique helicitic texture in certain inclination angle; on thin bar; conveniently deposit; whole device all have employed insulating material or insulation system, prevents from producing electric people's accident because of electric leakage.
Accompanying drawing explanation
Fig. 1 is the utility model cable fixing head installation diagram;
Fig. 2 is the utility model cable fixing head structural representation;
Fig. 3 is vacuum layer structural representation;
In figure, 1-nut, 2-pad, 3-main body, 4-water proof ring, 5-locknut, 6-spiral, 7-passage, 8-clamp jaw, 9-groove, 10-vacuum layer, 11-filled insulation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1
A kind of cable fixing head, as shown in Figure 1-2, nut 1 is connected with main body 3 by pad 2, and main body 3 is connected with water proof ring 4, and water proof ring 4 is connected with locknut 5;
Described locknut 5 is tapered structure, and skin is provided with spiral 6;
2-4 bar passage 7 is provided with in described water proof ring 4; The corresponding cable of each passage, ensures that cable does not rub in gland, not kinking.
One end of described main body 3 is provided with the screw thread matched with nut 1, and the other end is provided with the clamp jaw 8 matched with water proof ring 4, correspondingly on water proof ring 4 is provided with groove 9.
As shown in Figure 3, the central authorities of the wall of described main body 3 and locknut 5 are provided with vacuum layer 10, and vacuum layer 10 is filled with filled insulation 11.Vacuum can be effectively adiabatic, but the wall of main body 3 and locknut 5 is very thin, if directly make vacuum layer, can damage because being subject to the squeezing action of external force, therefore, installs filled insulation additional and can play support and protective effect.
The length of described locknut 5 is 1.5-3 times of main body 3 length.The length setting of locknut is a key of the present embodiment, if arrange too short, then because the degree of freedom of cable in this gland is large, produce the probability rubbing and lose large, if arrange oversize, then cable is little in the gland internal degree of freedom, is not easy to install, by experiment repeatedly draw the length of locknut 5 be the 1.5-3 of main body 3 length doubly for suitable, the optimization length of locknut 5 is 2 times of main body 3 length.
Described pad 2, nut 1 and water proof ring 4 adopt insulating material to make.
The screw thread of described spiral 6 and the inclination angle of horizontal plane are 25-45 °.
The cable fixing head of the present embodiment arranges tapered locknut; can available protecting electric wire; prevent locknut end and electric wire friction from losing, with the frictional force of hand or back-up wrench when spiral can increase on the one hand installation, it is easy to install; on the other hand; locknut can be fixed on rope by the oblique helicitic texture in certain inclination angle, on thin bar, conveniently deposits; whole device all have employed insulating material or insulation system, prevents from producing electric people's accident because of electric leakage.
