Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] FIG. 1 shows a female connector 6 of the present invention, and the female connector 6 includes an outer conductor 61 and an inner conductor 62 . There is an oblique angle 615a between the electrical mechanical reference plane 614 of the outer conductor 61 and the cylindrical surface 615, which is mainly used for leading in and out of the male connector. The outer surface of the outer conductor 61 is provided with an annular protrusion. The annular protrusion includes a guide slope 616 on the side of the joint reference surface 614 of the female connector and a support slope 618 opposite to the guide slope 616. The guide slope 616 and the support slope 618 are directed to A flat top 617 can be synthesized outside.

[0024] FIG. 2 shows the male connector 7 of the present invention. The male connector 7 includes a...

Abstract

When the coaxial connector in radio frequency is in connected state, gap of joint reference planes between male and female connectors is zero. At the same time, the coaxial connector can keep large axial directional contact pressure, and good axiality. There is annular bulge on surface of outer conductor of female connector. The annular bulge includes a bearing inclined plane. Dish shaped lock sheet with multiple teeth is setup inside male connector. When male connector and female connector are in connection state, the bearing inclined plane bears the lock sheet. Tangential force is generated between the lock sheet and the bearing inclined plane, and thrust is generated along normal direction at contact point of the bearing inclined plane. Thus, reference plane of female connector presses reference plane of male connector. Reducing volume and lightens weight, the coaxial connector is applicable to civil or industrial equipment, and areas of aviation and spaceflight.

Description

technical field [0001] The invention relates to a radio frequency coaxial connector, in particular to a self-locking radio frequency coaxial connector used in the communication industry and capable of quick insertion and extraction. Background technique [0002] RF coaxial connector is an electromechanical component specially used to connect various ports that transmit electromagnetic waves. It can be used for high-frequency instruments, output and input ports of instruments, connections between functional modules in communication stations, and radio transmission. The connection between the antenna and the transmitting module. In order to effectively transmit electromagnetic wave signals and energy, the RF coaxial connector must have a characteristic impedance that matches the characteristic impedance of the connected system, and the reflection coefficient and insertion loss of the connector itself must be small, and must have good shielding efficiency and low Intermodulati...
