Embodiment Construction

[0010] 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...

Abstract

The invention discloses a micro-miniature radiofrequency coaxial-connector. The radiofrequency coaxial-connector includes a front-positioned insulating sleeve (1), a rear-positioned insulating sleeve(2), a plug (3) with cables, a plug core (4), a socket shell (5), a rubber pad (6), a cap (7) and a locking screw (8); a socket is composed of the front-positioned insulating sleeve (1), the rear-positioned insulating sleeve (2), the plug core (4) and the socket shell (5); the middle of the plug core (4) is provided with a knurl which can increase frictional force between the plug core (4) and thefront-positioned insulating sleeve (1), and the plug core (4) and the front-positioned insulating sleeve (1) are arranged in an interference fit mode. The plug (3) with the cables can be inserted into the socket, the rubber pad (6) is placed between the rear end surface of the plug (3) with the cables and the cap (7), the cap (7) is fixed through the locking screw (8), and therefore the connection and locking of the plug (3) with the cables and the socket can be achieved. The height of the radiofrequency coaxial-connector occupies small space, connection is reliable, and the transmission of medium and low frequency signals can be achieved.

Description

technical field [0001] The invention relates to a radio frequency coaxial connector, in particular to a miniature radio frequency coaxial connector. Background technique [0002] 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 i...
