Problems solved by technology

For example, a "triple coaxial connector" disclosed in Chinese patent CN2138843Y is a coaxial conductor joint used on electrical penetrations of nuclear reactors. It uses ceramic materials as insulating materials, and the overall sealing is ensured through sleeve sealing welding technology. Performance, because most of the parts are connected by welding process, which leads to poor interchangeability, complicated process, and increases the cost of the product; another problem is that the use of triple coaxial connectors is less, which has gradually been used disuse

Embodiment Construction

[0042] Such as figure 1 , Figure 4 Shown: a coaxial conductor joint, which is composed of a coaxial socket and a coaxial plug connected through a thread 22.

[0043] coaxial sockets, such as figure 2 Shown: socket compression nut 1, compression nut ferrule 2, ferrule nut 3, outer shielding sleeve 4, fluorine rubber built-in "O" seal ring 5, fluorine rubber external "O" seal ring 6, The EKK rigid conductor insulating cladding 7, the EKK ferrule insulating cladding 8 and the bronze metal ferrule 9 are composed of components.

[0044] The specific structure of the coaxial socket is as follows:

[0045] The compression nut ferrule 2 is installed in the cavity of the ferrule nut 3, and the socket compression nut 1 inserted in the cavity at the end of the ferrule nut 3 compresses the compression nut ferrule 2 on the ferrule Inside the cavity of the nut 3;

[0046] At the other end of the ferrule nut 3, an ether ether ketone rigid conductor insulating cladding 7 is butted, and...

Abstract

The invention discloses a coaxial conductor joint which comprises a coaxial socket and a coaxial plug. The coaxial socket comprises a socket compaction nut, a compaction nut cutting sleeve, a cutting sleeve nut, an outer shielding housing, a built-in O-shaped obturating ring, an outlay O-shaped obturating ring, a rigid conductor insulating envelope, a lock pin insulating envelope and a metal lock pin; the coaxial plug comprises a connecting nut, a metal contact pin, a inner insulating contact pin seat, an outer contact pin seat, a connecting sleeve, a compaction bolt, a compaction bolt cutting sleeve and a plug compaction nut. The insulating envelopes adopts high-performance polyether-ether-ketone plastic; coaxial socket sealing is realized by the metal cutting sleeves and the obturating rings, and the electrical connecting from a coaxial cable to a rigid conductor is realized by the lock pin matching with the contact pin. The invention has simple structure, good leak tightness, convenient operation, long service life, good anti-interference and irradiation resistance, is convenient for part maintenance and interchanging, and suitable to be used on an electrical perforating piece of a reactor safe shell, and also can be used on relative equipment of spaceflight and chemical engineering.

Description

technical field [0001] The invention relates to a coaxial connector, in particular to a coaxial conductor joint specially used for connecting rigid coaxial conductors and flexible coaxial cables. Background technique [0002] The coaxial connector is connected with other coaxial components to form a radio frequency coaxial transmission line, which is generally used for signal transmission and connection of electrical devices, and is the main component of the radio frequency coaxial transmission system. It is required to maintain the effectiveness, consistency and stability of electrical performance in various assembly and use environments, and it can be easily assembled and maintained under various application conditions. Generally, coaxial connectors must meet the requirements of the installation and use environment, and the selection of materials and structural design are often more important than the selection of electrical performance requirements, because these requirem...
