Embodiment 1

[0015] The basic structure of a double-wedge RF connector in this embodiment is as follows: figure 1 and figure 2 As shown, the front shell 7 and the rear screw sleeve 11 are connected by screwing, and the inner conductor 5 is isolated in the front shell 7 by the insulator 6 . One end of the front housing 7 adjacent to the rear screw sleeve 11 has an internal thread, and the internal thread is adjacent to the first tapered hole with a positioning step. One end of the rear threaded sleeve 11 adjacent to the front shell 7 has an external thread section, and the inner hole of the external thread section is a second tapered hole opposite to the taper direction of the first tapered hole. The first cone hole is equipped with a first C-shaped outer cone ring (commonly known as a bushing) 2 whose inner diameter matches the outer diameter of the cable outer conductor, and the second cone hole is equipped with a second C-shaped ring whose inner diameter matches the outer diameter of t...

Abstract

The invention relates to a double wedge type radio frequency connector, which belongs to the technical field of communication transmission facilities. The connector comprises a front shell, a rear turn buckle and an inner conductor, wherein one end, close to the rear turn buckle, of the front shell is in adjacent connection with a first taper hole with a positioning stage; an inner hole, close to an external screw thread segment of the front shell, of the rear turn buckle is a second taper hole; a first C-shaped outer taper ring is assembled in the first taper hole, a second C-shaped outer taper ring is assembled in the second taper hole, and the opening of the first C-shaped outer taper ring and the opening of the second C-shaped outer taper rings are wider than an axial convex rib of a cable protective cover; and when the front shell and the rear turn buckle are connected and screwed through screw threads, the opposite end surfaces of the first and second C-shaped outer taper rings contact in a way of pressing against each other, and the inner diameters of the first and second C-shaped outer taper rings tend to reduce simultaneously. When the double wedge type radio frequency connector is used, the shell is wedged, connected and clamped with the outer conductor and the outer circle of a cable reliably at the same time; and the axial convex rib part of the cable protective cover is not required to be removed, so connection operation is obviously simplified and very convenient.

Description

technical field [0001] The invention relates to an electrical signal connector, in particular to a double-wedge radio frequency connector, which belongs to the technical field of communication transmission facilities. Background technique [0002] There are many kinds of radio frequency connectors, and its basic function is to realize the reliable electrical connection between the inner shell and the outer shell and the core and outer conductor of the communication cable by means of its own connection structure, so as to further realize the plugging with the corresponding plugging device. [0003] As far as the applicant knows, the standard N, 7 / 16 connector is a high-power connector with a threaded structure that conforms to the IEC169-4, -16 standard. It has the characteristics of strong vibration resistance, excellent mechanical and electrical performance, and is widely used in information on trains. It is used for connecting radio frequency coaxial leakage cables in tran...
