Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a 5G is waveguide leaky cable for communication, including inner conductor 1, the outer wall parcel of inner conductor 1 has insulator 2, the outer wall parcel of insulator 2 has outer conductor 3, round hole 4 has been seted up to outer conductor 3's right-hand member outer wall, the outer wall parcel of outer conductor 3 has spacer sleeve 5, a plurality of square groove 6 has been seted up to spacer sleeve 5's outer wall, the even distribution in spacer sleeve 5's outer wall of dry individual square groove 6, the intussuseption of square groove 6 is filled with first fire retardant 7, spacer sleeve 5's outer wall parcel has fibrous layer 8, the inside infiltration of fibrous layer 8 has second fire retardant 9, and remain between fibrous layer 8's surface and fibre after the drying of second fire retardant 9, fibrous layer 8's outer wall parcel has sheath 10, first fire retardant 7 and second fire retardant 9 can effectual improvement leaky coaxial cable's flame retardant performance.

Particularly, the right-hand member outer wall of insulator 2 corresponds round hole 4 and has seted up compensation hole 11, and the inner wall fixedly connected with beaded finish 12 of round hole 4, and beaded finish 12 are the copper ring, and the inboard outer wall of beaded finish 12 is pegged graft mutually with the inner wall in compensation hole 11 to when avoiding leakage coaxial cable to buckle, the round hole department of outer conductor tears, avoids increasing the coupling and consumes.
