Utility model content
The purpose of this utility model be to provide a kind of simple to operate, can with the power cable linear pattern splicing ear head of electrical connection.
The utility model discloses a kind of power cable linear pattern splicing ear head, comprise 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 link of bonding conductor all adopts screw connection structure, bonding conductor is cylinder, and the link at the two ends of its axial centre is the internal thread hole that thread rotary orientation is contrary, and the outer wall of rear end internal thread hole has the locating ring of evagination.
The spanner gripping section that the leading portion of described rigid insulation cover is cylindricality arc control device, interlude is hexagonal prism shape, back segment are cable joining room, stress tube is furnished with in cable joining room, cable joining room outer wall has ground lead connecting hole, and cable joining room outer wall end is connected with rigid insulation capping by external screw thread.
The length of described bonding conductor is less than the degree of depth of described cylindricality arc control device, the axial centre that the cylindricality arc control device insulation and obturation that bonding conductor is all in described rigid insulation cover with front and rear end overlaps in rigid insulation.
The front end of described splicing ear body is connected with end socket, end socket is the single piece of inner conductor and the integration of external hard plastic insulator, inner conductor 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; The leading portion that end socket is placed on splicing ear rigid insulation cover with its rigid insulation body is outer, inner conductor is threaded with the front end internal thread hole of splicing ear 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 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; In order to make attended operation faster, the spanner gripping section on splicing ear body is made to be hexagonal prism section; 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 a kind of power cable linear pattern splicing ear head, comprise splicing ear body, splicing ear body is the single piece that bonding conductor 1 and rigid insulation overlap 2 integrations, and bonding conductor 1 insulation and obturation is in the axial centre of rigid insulation cover 2.
Bonding conductor 1 is cylinder, and the two ends of its axial centre are the internal thread hole that thread rotary orientation is contrary, and the outer wall of rear end internal thread hole has the locating ring of evagination.The spanner gripping section 22 that the leading portion of rigid insulation cover 2 is cylindricality arc control device 21, interlude is hexagonal prism shape, back segment are cable joining room 23, stress tube is furnished with in cable joining room 23, cable joining room 23 outer wall has ground lead connecting hole 24, and cable joining room 23 outer wall end is connected with rigid insulation capping 4 by external screw thread.The length of bonding conductor 1 is less than the degree of depth of cylindricality arc control device 21, and bonding conductor 1 is all in cylindricality arc control device 21 insulation and obturation of rigid insulation cover 2 in the axial centre of rigid insulation cover 2 with front and rear end.
The axial centre of rigid insulation capping 4 has shoulder hole, and the bigger diameter end of shoulder hole is internal thread hole.The front end of splicing ear body is connected with end socket 5, end socket 5 is the single piece of inner conductor 51 and external hard plastic insulator 52 integration, inner conductor 51 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.The leading portion that end socket 5 is placed on rigid insulation cover 2 with its rigid insulation body 52 is outer, inner conductor 51 is threaded with the front end internal thread hole of bonding conductor 1.
This splicing ear, when not using, connects end socket 5 and rigid insulation capping 4 respectively in its front-end and back-end, and simultaneously supporting rubber blanket 6, to protect screw thread and to make bonding conductor keep clean dry.
