Description

A micro-miniature radio frequency coaxial connector

technical field

The invention relates to a radio frequency coaxial connector, in particular to a miniature radio frequency coaxial connector.

Background technique

RF coaxial connectors are widely used in aviation, aerospace, national defense, communication and other industries. With the rapid development of miniaturized and highly integrated electronic products, the demand for light, small and high-reliability RF coaxial connectors has become increasingly urgent. The existing RF coaxial connectors include SMA series, SSMA series, and MCX series etc. The SMA series and SSMA series are screw locking type, with high connection reliability, but the height takes up a lot of space, which sometimes cannot meet the product design in a small space. Although the MCX series occupies a small space, it is crimping and locking. Type, low reliability, under transportation and vibration conditions, it may lead to unreliable connection between the plug and the socket, and it may cause the plug and socket to fall off completely.

Contents of the invention

The purpose of the present invention is to provide a micro-miniature radio frequency coaxial connector, which solves the problems that the existing threaded locking type radio frequency coaxial connector occupies a large space or the crimping and locking type radio frequency coaxial connector is unreliable in connection.

A micro-miniature radio frequency coaxial connector, including: a front insulating sleeve, a rear insulating sleeve, a plug with a cable, and also includes: a ferrule, a socket shell, a rubber gasket, a cap and a locking screw. The front insulating sleeve, the rear insulating sleeve, the ferrule and the socket housing are composed of four parts. The ferrule is made of beryllium bronze and the surface is gold-plated. Knurled. The front insulating sleeve and the rear insulating sleeve are both made of polytetrafluoroethylene rods. The front insulating sleeve is a sleeve-like structural member with three concentric steps on the outside and two concentric holes inside. The insulating sleeve is a hollow sleeve structure with two concentric steps on the outside. The ferrule and the front insulating sleeve are interference fit, and the knurling on the ferrule can increase the gap between the ferrule and the front insulating sleeve. Friction, so that the two are not easy to fall off. The socket housing is a square structure with four levels of concentric holes inside. The socket housing also has four light holes and two threaded holes. Both are interference fit, and the cap is a "U"-shaped structural member with two mounting holes.

When in use, insert the plug with cable into the socket, place the rubber pad between the rear end face of the plug with cable and the cap, and fix the cap with two locking screws, so as to realize the plug with cable Connection and locking of plug and socket.

The coaxial connector is novel in design, takes up little space in height, and has high connection reliability. It can realize medium and low frequency signal transmission. It can be used in aviation, aerospace, national defense, communication and other industries, and provides technical basis for the selection of subsequent related product components.

detailed description

A micro-miniature radio frequency coaxial connector, including: a front insulating sleeve 1, a rear insulating sleeve 2, a plug 3 with a cable, and also includes: a ferrule 4, a socket housing 5, a rubber gasket 6, and a cap 7 , locking screw 8. The socket is composed of four parts: a front insulating sleeve 1, a rear insulating sleeve 2, a ferrule 4, and a socket housing 5. The ferrule 4 is made of beryllium bronze and the surface is gold-plated. Hole, with a section of knurling in the middle, the front insulating sleeve 1 and the rear insulating sleeve 2 are made of PTFE rods, the front insulating sleeve 1 has three concentric steps on the outside, and two steps on the inside Sleeve-type structural parts with concentric holes, the rear insulating sleeve 2 is a middle-hole sleeve-like structural part with two concentric steps on the outside, the ferrule 4 and the front insulating sleeve 1 are interference fit, and the ferrule 4 The knurling on the top can increase the friction between the ferrule 4 and the front insulating sleeve 1, so that the two are not easy to fall off. The socket housing 5 is a square structure with four levels of concentric holes inside. The socket housing 5 also has four light holes and two threaded holes. The socket housing 5 is connected to the front insulating sleeve 1 and the rear The insulating sleeves 2 are all interference fit, and the cap 7 is a "U"-shaped structural member with two mounting holes.

When in use, insert the plug 3 with the cable into the socket, place the rubber gasket 6 between the rear end surface of the plug 3 with the cable and the cap 7, and fix the cap 7 with two locking screws 8, Thereby, the connection and locking between the plug 3 with the cable and the socket are realized.
