Abstract
The utility model provides a microstrip type antenna electronic lightning arrester which comprises a back-up block which is provided with a coaxial microstrip transducing head and an earthing strip, a housing which is connected with the back-up block and forms a cavity, and a microstrip circuit board which is arranged in the cavity and fixed on the back-up block. The circuit connection of the utility model is that both ends of a capacitor C1 are respectively connected with the input terminal and the output terminal of a microstrip transmission line, and an induction coil L1, a capacitor C3, an L2 and a C4 are respectively connected with the input terminal, antenna feeder field, the output terminal and equipment field. Both ends of the capacitor C2 are connected with the antenna feeder field and the equipment field. The utility model has simple structure, which is suitable for protection of middle and small power communications, televisions, CATV, satellite televisions, radars, etc.
Description
The utility model relates to a kind of lightning arrester, particularly relates to a kind of microstrip type antenna feeder electronics lightning arrester.
Thunder and lightning is regarded as one of maximum natural calamity, protects valuable electronic equipment to exempt from thunderbolt and has caused very big attention.Traditional antenna feeder electronics lightning arrester is to adopt Zinc-oxide piezoresistor at present, gas discharge diode and bidirectional diode design, and its operating frequency upper limit, indexs such as frequency bandwidth, insertion loss and standing wave are all relatively poor.Chinese patent 91214741.5 discloses a kind of lightning protection in base station device, it comprises the cylindrical shell shape shell that is threaded each other by three sections, the cavity that is made of two identical box bodys and cover plate is arranged in the stage casing, fastening identical micro belt board in each box body, three little bands, a following little band ground connection are arranged on it, and little being with is welded with electric capacity and inductance.This lightning arrester complex structure, operating frequency range are narrower, and input power is lower, and it is bigger to insert loss, and thunder and lightning is through-flow less.
The purpose of this utility model is to provide a kind of simple in structure, microstrip type antenna feeder electronics lightning arrester of being provided with the π type high-pass filtering network that is made of microstrip transmission line, electric capacity and inductance.
The utility model microstrip type antenna feeder electronics lightning arrester is to realize like this, it comprises the bracing frame that is provided with coaxial microband conversion head and ground strip, be connected with bracing frame and with the shell of its formation cavity, and be positioned at cavity and be fixed on micro belt board on the bracing frame.Shell generally is connected with screw etc. with back-up block.The coaxial microband conversion head is fixed on the back-up block both sides, and stretches in the cavity, and its inner wire is welded on the micro belt board.Micro belt board can be screwed on back-up block.Wherein the circuit on the micro belt board is connected to, the two ends of capacitor C 1 connect microstrip transmission line input and output respectively, inductance L 1 and distributed capacitance C3 are connected between microstrip transmission line input and the antenna feeder ground, inductance L 2 and distributed capacitance C4 are connected between microstrip transmission line output and the equipment ground, capacitor C 2 two ends connect respectively between antenna feeder ground and the equipment ground, microstrip transmission line input, output connect the inner wire of coaxial microband conversion head simultaneously.Convenient for lightning arrester is installed, installing hole can be set on shell, be fixed on the wall or other place with securing member.
The microstrip transmission line input connect antenna by coaxial little conversion head when the utility model microstrip type antenna feeder electronics lightning arrester used, and output connects protected equipment by another coaxial microband conversion head, and ground strip connects antenna feeder ground and equipment ground respectively.Its course of work is that radio frequency (RF) signal enters the π type high-pass filtering network that is made of L1, L2, C1, C2, C3 and C4 by microstrip transmission line, exports to output.The high-frequency loss of high pass is minimum, and highest frequency can reach more than the 3GHz, and high pass presents the stopband feature at low frequency 1HZ～1MHz, and decay reaches 100～300dB.When lightening pulse is imported from microstrip transmission line, can not pass through from radio-frequency head, can only be from inductance L 1 to ground, thus protection equipment avoids thunderbolt to destroy.
The advantage of the utility model microstrip type antenna feeder electronics lightning arrester is simple in structure, and volume is little, and operating frequency range is more than 10～2000MHz; insert loss at 0.2～0.4dB; be applicable to the communication of middle low power, TV, CATV, each class of electronic devices lightning protection such as satellite television, radar.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
