Utility model content
The purpose of this utility model is to provide a kind of with electrical connection, the T-shaped splicing ear head of power cable simple to operate.
The utility model discloses the T-shaped splicing ear head of a kind of power cable, comprise T-shaped splicing ear body, splicing ear body is the single piece of inner bonding conductor and the integration of outside rigid insulation cover, bonding conductor insulation and obturation is in rigid insulation cover, the connecting interface of bonding conductor all adopts screw connection structure, the shape of bonding conductor is T-shaped, and its three interfaces are internal thread interface.
The shape of described rigid insulation cover is T-shaped, T-shaped hole is had in it, described bonding conductor is flush-mounted in T-shaped hole, the length of rigid insulation cover is greater than the length of bonding conductor, the two ends in its coaxial line direction form arc control device I and arc control device II respectively, cable joining room is formed at the bottom in another direction, is furnished with stress tube, the outer wall of cable joining room has ground lead connecting hole, cable joining room outer wall end is connected with rigid insulation capping by external screw thread in it.
In the arc control device I of described rigid insulation cover, empty size equals empty size in arc control device II.
The two ends supporting screw type end socket having inner conductor and the integration of external hard plastic insulator respectively of described splicing ear body coaxial line, the inner conductor of screw type end socket is the metal screw of band locating ring, the vertical sectional shape of rigid insulation body is U-shaped, metal screw insulation and obturation is in the axial centre of rigid insulation body, and the outer face of metal screw is positioned at the openend end face of rigid insulation body.Screw type end socket is placed on outside described rigid insulation cover with its rigid insulation body, inner conductor is threaded with the internal thread hole of described bonding conductor.
The axial centre of described rigid insulation capping has shoulder hole, and the bigger diameter end of shoulder hole is internal thread hole.
All supporting rubber blanket when described rigid insulation capping is connected with described splicing ear body with screw type end socket.
Cable first crimps with thread head Wiring nose and is integrated, and thread head Wiring nose and splicing ear body of the present utility model are threaded connection and are integrated.Take off end socket during use to be connected with wall bushing or electric equipment band electrical connecting member by butt joint.When butt joint connects wall bushing or electric equipment band electrical connecting member and splicing ear body, because the complete insulation and obturation of the bonding conductor of splicing ear body is in rigid insulation cover, the junction of bonding conductor is in arc control device, only insulating material is contacted during operated by personnel, make splicing ear body can realize band electrical connection operation, thus reduce power failure range, be beneficial to safe power supply.Simple to operate, only need rotate butt joint during installation and removal.
In order to the integrity of the clean drying and its screw thread that ensure splicing ear body, the link of splicing ear body is first sealed with end socket, and arranging of rubber blanket can prevent from loosening between adjacent connections and having waterproof and dampproof effect.
Accompanying drawing explanation
Fig. 1 is the detonation configuration schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, present embodiment discloses the T-shaped splicing ear head of a kind of power cable, comprise T-shaped splicing ear body, splicing ear body is the single piece that inner bonding conductor 1 and outside rigid insulation overlap 2 integrations, and bonding conductor 1 insulation and obturation is in rigid insulation cover 2.
The shape of bonding conductor 1 is T-shaped, and its three interfaces are internal thread interface.The shape of rigid insulation cover 2 is T-shaped, T-shaped hole is had in it, bonding conductor 1 is flush-mounted in T-shaped hole, the length of rigid insulation cover 2 is greater than the length of bonding conductor 1, the two ends in its coaxial line direction form arc control device I 21 and arc control device II 22 respectively, cable joining room 23 is formed at the bottom in another direction, is furnished with stress tube 3, the outer wall of cable joining room 23 has ground lead connecting hole 24, the outer wall end of cable joining room 23 is connected with rigid insulation capping 4 by external screw thread in it.The axial centre of rigid insulation capping 4 has shoulder hole, and the bigger diameter end of shoulder hole is internal thread hole.
The two ends supporting screw type end socket 5 having inner conductor 51 and external hard plastic insulator 52 integration respectively of splicing ear body coaxial line.The inner conductor 51 of screw type end socket 5 is the metal screw of band locating ring, the vertical sectional shape of rigid insulation body 52 is U-shaped, metal screw insulation and obturation is in the axial centre of rigid insulation body 52, and the outer face of metal screw is positioned at the openend end face of rigid insulation body 52.Screw type end socket 5 is placed on outside rigid insulation cover 2 with its rigid insulation body 52, inner conductor 51 is threaded with the internal thread hole of bonding conductor 1.
