N type joint

Abstract

The invention discloses an N type joint which can be quickly assembled to a leaky cable and has good electrical performance, and belongs to the technical field of communication equipment. The N type joint comprises a first joint body and a second joint body which are in threaded connection, the N type joint comprises C-shaped cable clamp with internal teeth and two bushes which form a V shape, the cable clamp and the bushes are located in an internal space formed after the first joint body and the second joint body are connected, the bushes wrap both ends of the cable clamp respectively, and an internal tooth profile of the cable clamp coincides with an outer profile of an outer conductor of a leaky cable that is connected. When the N type joint in the invention is connected with the leaky cable, only a sheath of an end part of the leaky cable needs to be stripped, a process of completely removing an insulating medium is omitted, in a process of screwing the first joint body and the second joint body together, and the bushes generate axial displacement and extrude the cable clamp with the internal teeth, thereby achieving the beneficial effects of quick assembling and small discreteness of electrical performance.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to a joint quickly connected to a leakage cable. Background technique [0002] Leaky cables are used in areas where general communication antennas are difficult to function, especially in areas where discrete antennas in mobile communication systems cannot provide sufficient communication coverage, such as mountains, hills, tunnels, underground railways, mines, underground buildings, shopping malls or other electromagnetic fields Blind spots of transmission. In these areas, due to the narrowness and obstruction of the surrounding environment, the antenna coverage is greatly limited, and because it is very close to the coverage object and the signal radiation direction is perpendicular to the radiation environment, it can provide a uniform field strength, so in these environments the wireless signal receiving device Leaky coax is the best means of wireles...

AI Technical Summary

Problems solved by technology

[0003] At present, the installation and installation of the coaxial connector connected with the leaking cable on the market is time-consuming and laborious. It is necessary to use a special hollower to hollow out the insulation medium of the specified length between the outer conductor and the inner conductor of the cable, and the hollowed-out size deviates greatly from the specified , resulting in large dispersion of voltage standing wave ratio in electrical performance; then strip off part of the sheath, and it takes about 10 minutes to install a single piece
