Description

A kind of high-frequency coaxial connector

Technical field

The utility model belongs to microwave components technical field, is specifically related to a kind of high-frequency coaxial connector.

Background technology

With extensive use of the phased array system in the complete electronic sets such as radar and communication, development and production great quantity of small is needed Change, high density and multifunction microwave component；The Micro-package technique of microwave components is to realize electronics miniaturization, lightweight, height The important technology approach of the targets such as density three-dimensional interconnection structure, wide working band, high working frequency and high reliability；High frequency coaxial Connector is an important composition factor in microwave components, and common high-frequency coaxial connector has：SMA connectors, SMP connections Device；Traditional high-frequency coaxial connector is different from other kinds of connector, and high-frequency coaxial connector is single independent individual, A socket including a plug and with plug pairing connection, only there are one high frequency feed-throughs for tool；For multichannel TR groups For part, need the socket (also referred to as female end) of multiple high-frequency coaxial connectors being assembled on electronic encapsulation shell successively, to Increase the difficulty and cost of assembling.

Chinese invention patent《Radio frequency (RF) coaxial connector》(publication number：101330181B；Publication date：On July 14th, 2010) In disclose a kind of radio frequency (RF) coaxial connector, including the socket and plug being mutually inserted；Socket is by A outer conductors, A insulators and A Inner wire is sequentially coaxially set with from outside to inside, and plug is same successively from outside to inside by B outer conductors, B insulators and B inner wires Axle sleeve fills；A outer conductor inner walls are equipped with annular groove；B outer conductors are the casing that one end is equipped with that convex rushes pack arrangement, Convex, which is rushed, is axially evenly distributed with several profile grooves on the casing of pack arrangement；B inner wires are clamped with A inner wires；The convex of B outer conductors is rushed Pack arrangement and the annular groove flexible clamping on A outer conductor inner walls, realize the coaxially connected of radio frequency；It follows that the radio frequency is same Mandrel connector is single independent individual, and only there are one high frequency feed-throughs for tool.

Invention content

In view of this, the purpose of this utility model is to provide a kind of high-frequency coaxial connector, by by multiple inner wires It is incorporated on a plate-like outer conductor so that there are multiple high frequency feed-throughs on the outer conductor, it being capable of all promising policy The multichannel requirement of microwave components advantageously reduces the difficulty and cost of assembling.

In order to achieve the above object, a kind of high-frequency coaxial connector of the utility model, including socket, the socket include outer Conductor, insulator and inner wire, outer conductor is plate-like, surface be equipped with N number of installation through-hole, inner wire, insulator be it is N number of, It is set in each installation through-hole there are one coaxial inner wire and connection between the two is there are one insulator, N is more than or equal to 2 Positive integer.

Further, N number of through-hole array formula arrangement.

Further, the insulator is circular ring shape sheet glass, circular ring shape sheet glass outer round surface and installation through-hole inner circle table Face sealing-in, circular ring shape sheet glass internal circular surfaces and inner wire outer round surface sealing-in.

Further, the dielectric constant of the insulator is 3.9~4.2.

Further, the material of the outer conductor and inner wire is kovar alloy.

The beneficial effects of the utility model are：

1. a kind of high-frequency coaxial connector of the utility model has broken traditional yoke, multiple inner wires are organically incorporated into On one outer conductor, i.e. there are multiple high frequency feed-throughs on an outer conductor, is capable of the mostly logical of all promising policy microwave components Road requirement；Advantageously reduce the difficulty and cost of assembling.

2. N number of through-hole array formula arrangement, meets phased array T/R groups described in a kind of high-frequency coaxial connector of the utility model The application conditions of the array multichannel of part.

3. a kind of high-frequency coaxial connector of the utility model is conducive to whole miniaturization；Since multiple inner wires are total It can be further reduced with the centre-to-centre spacing of an outer conductor, two neighboring inner wire.

It is easy to process, be simple to manufacture 4. a kind of high-frequency coaxial connector of the utility model, be conducive to be further reduced into This；Multiple installation through-holes only need to be processed on plate outer conductor, then pacified inner wire sealing-in by glass head seal technique Fill through-hole inside.
