Description

Wire nose convenient to installation and dismantlement

Technical Field

The utility model relates to an electrical components technical field, more specifically say, it relates to a line nose.

Background

The wire nose is usually used for connecting and splicing the tail end of the cable, so that the cable and an electric appliance can be connected more firmly and more safely. Is a common material for buildings, power equipment, electrical appliance connection and the like. The wire noses currently used have the following disadvantages: 1. in actual life, the wiring nose is easily oxidized and rusted due to improper long-time placement and storage, so that the wiring nose is difficult to screw down in the conductive barrel by using a tool when being disassembled, assembled and replaced. 2. The joint space of the wire nose is thicker than that of the cable head, and in the process of pressing the wire nose by using hydraulic pliers, only one or two parts are pressed under most conditions, and at least one third of the space of the wire nose cannot be in close contact with the cable;

in summary, the following steps: there is a need for a wire lug that has a simple structure, is easy to assemble and disassemble, and can be in full contact with a cable.

The utility model discloses further set up to: and one end of the rear sleeve, which is far away from the third external thread, is an expansion end, and a notch is formed in the expansion end.

By adopting the technical scheme, the length of the expansion end is one fourth to one third of the length of the rear sleeve, the length of the cut part is one half of the length of the expansion end, and the cut on the expansion end can be conveniently installed with other parts.

The utility model discloses further set up to: and a second nut is arranged on the outer surface of the rear sleeve and can rotate and move to the expansion end.

Through adopting above-mentioned technical scheme, during the use, pass the back cover to the cable, the second nut of rotation moves towards the inflation end after that, cramps the inflation end, and the inflation end cramps the cable conductor again and just can be put on the back cover and can not drop the firm connection of cable conductor, has strengthened joint strength between them.

The utility model discloses further set up to: the diameter of the expansion end is gradually increased from right to left.

Through adopting above-mentioned technical scheme, can be convenient for with being connected of second nut, can also prevent that the second nut from droing.

The utility model discloses further set up to: and a plurality of blunt-end sawteeth are arranged on the inner wall of the expansion end.

Through adopting above-mentioned technical scheme, blunt nosed sawtooth evenly distributed is on inflation end inner wall, and when inflation end cramp cable conductor, blunt nosed sawtooth can increase the pressure of inflation end to the cable conductor, can further increase the fastening effect of inflation end to the cable conductor.

The utility model has the advantages that: the sleeving connection of the cable is simple in operation, the dismounting steps are simple, the cable can be firmly fixed, and the contact area between the cable and the wire nose can be increased.

Detailed Description

The present invention is further described with reference to fig. 1.

The utility model provides a line nose convenient to installation and dismantlement, including the antetheca 1, back cover 2, the wiring circle 3, the antetheca 1 comprises endotheca 12 and overcoat 11, the diameter of overcoat 11 is greater than the diameter of endotheca 12, be equipped with first external screw thread 5 on the 12 outer walls of endotheca, be equipped with the internal thread 4 with 5 adaptations of first external screw thread on the 2 inner walls of back cover, overcoat 11 is the same with the outer wall diameter of back cover 2, be equipped with second external screw thread 6 on the outer wall of overcoat 11, be equipped with third external screw thread 7 on the outer wall of back cover 2, second external screw thread 6 is the same with third external screw thread 7, be equipped with first nut 14 on the back cover 2, third external screw thread 7 and second external screw thread 6 are connected through first nut 14, terminal surface fixed connection before wiring circle 3 and overcoat 11, the inner wall top of overcoat 11 is equipped with. The front sleeve 1 and the rear sleeve 2 are connected through the first nut 14, so that the front sleeve 1 and the rear sleeve 2 are convenient to mount and dismount, the front sleeve 1 consists of the outer sleeve 11 and the inner sleeve 12, the outer sleeve 11 and the inner sleeve 12 are connected through welding, the connection is firmer, the outer sleeve 11 and the inner sleeve 12 are prevented from falling off, and the inner sleeve 12 is convenient to connect with the rear sleeve 2 because the diameter of the outer wall of the inner sleeve 12 is smaller than that of the outer wall of the outer sleeve 11.
