Double wedge type radio frequency connector

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...

Problems solved by technology

However, the above-mentioned existing clamping structure has the following problems: 1) the cable and the outer conductor therein need to be clamped separately, which is not only cumbersome to install, but also difficult to clamp; 2) the axial ribs of the outer sheath of the cable Some parts need to be repaired; 3) The inner conductor of the cable needs to be tapped

However, this structure is difficult to be directly used to solve the above problems
