Problems solved by technology

When the AC or DC power is fed to the tower through the feeder line and the lightning protection coaxial connector, since the lightning protection connector uses a gas discharge tube with a freewheeling effect, a freewheeling phenomenon will occur under the action of lightning, The signal is short-circuited, the system cannot work normally, and in severe cases, the equipment will be damaged
The freewheeling effect of the air discharge tube limits the use of lightning protection coaxial connectors

Embodiment Construction

[0015] Various embodiments will be described in detail below in conjunction with the accompanying drawings.

[0016] Fig. 1 is a structural schematic diagram of the first embodiment of the lightning protection coaxial connector of the present invention, including a housing 1 as the outer conductor of the connector, an inner conductor 2, an insulating medium 5, 7 between the housing and the inner conductor, and the housing 1 Made of copper alloy or aluminum alloy, as the outer conductor of the connector, the shell has three parts connected along the axial direction, that is, the first section 11 on the left in Figure 1, the second section 12 on the right, and The end caps 13 between them, each with an inner bore, can have respective different outer diameters. In this example, the outer cylindrical surfaces of the first section 11 and the second section 12 are threaded, and the parts connected therewith are threaded. The outer peripheral surface of the end cap 13 can be made in...

Abstract

A lightning protection subassembly is connected between inner and outer conductor of a connector electrically. The lightning protection subassembly is composed of two or more nonlinear elements, or a nonlinear element of not type of gas discharge tube. Electrical connection between elements can be in parallel, serial or composite connection. Nonlinear elements can be in types of piezoresistor, gas discharge tube, and diode of restraining transient voltage, solid discharge tube or other nonlinear elements. The coaxial connector in lightning protection type possesses function of connection, and function of lightning protection. Features are: good performance of microwave transmission without disadvantage of follow current existed in gas discharge tube, cheap price, and high reliability. The invention can be applicable to transient over voltage protection to diversified wireless communication devices and cable TV systems.

Description

technical field [0001] The invention belongs to coaxial connectors, in particular to a coaxial connector with lightning protection function and no freewheeling effect. Background technique [0002] Coaxial connectors are widely used in various wireless communication equipment, cable TV and other systems as their input and output terminals. In order to protect the system from lightning, antenna feeder surge protectors are widely used, which are connected to the feeder system through coaxial connectors. . [0003] Utility model patent No. ZL01247642.0 discloses a lightning protection coaxial connector, which integrates a coaxial gas discharge tube as a lightning protector and a coaxial connector, which significantly simplifies the overall configuration and reduces the installation process. [0004] However, in order to improve the communication quality of wireless communication equipment or increase the communication distance, a technical measure that can be taken is to insta...
