Abstract

A deflecting RF coaxial connector is composed of a positive connector (8) and a negative connector (9). It is characterized in that one end inner surface of an insulator (2) of the positive connector (8) is loudspeaker shape, and another end cavity (7) inner surface is curve surface. The end head outer surface of inner insulator (5) of the negative connector (9) is spherical surface. The end head of the inner insulator (5) of the negative connector (9) is joined with the cavity (7) of the positive connector (8). Because the spherical end head of the inner insulator of the negative connector is coupled with the curve cavity of the positive connector, the negative and the positive connector can deflect certain angle when they are inserted to each other along the central axes, so the technology problem that it is bad for neutral when inserting the connectors is solved.

Description

Deflect Radio Frequency Coaxial Union

Technical field

The utility model belongs to the radio frequency (RF) coaxial connector of the electronic connector class of using in the communication system, particularly a kind of Deflect Radio Frequency Coaxial Union.

Background technology

Along with the development of mechanics of communication, the volume of equipment such as various the army and the people's microwave communications, mobile communication, fine measuring instrument is tending towards miniaturization, microminiaturization day by day.Therefore, the connector that is used for these equipment need carry out socket in very intensive space.At present a large amount of screw thread couplings that use or fast socket, connector be to after inserting, and male connector and female connector are connected by screw thread or special locking mechanism, axiality requirement height, and axis deflects relatively.When the connector of group more than needs are installed in same circuit board, because all necessary coaxial installation of each connector, therefore, the relative position of each connector then needs very accurate, when a pair of the installation because of disalignment in many groups connector caused and can't then can cause whole group panel or equipment to install when inserting.

The utility model content

The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, provide a kind of both can the interfix self-locking, and axis and deflecting relatively, and can guarantee to connect reliable has the Deflect Radio Frequency Coaxial Union of excellent conductive performance.

Technical solution of the present utility model is: an end inner surface of male connector insulator is one horn-like, and other end cavity inner surface is a curved surface; The termination outer surface of insulator is a sphere in the female connector.

Further technical solution of the present utility model is: in the female connector peg graft mutually with the cavity in the male connector and cooperate in the termination of insulator.All have dilatation joint on the inner wire of male connector and outer conductor, the end face of female connector is provided with horn mouth.Diameter in the cavity in the male connector is greater than the diameter of its closing in.

By above-mentioned technical solution as can be seen, the utility model is owing to be designed to big and the shape that port slightly closes up in inner space with the cavity in the male connector, and the inner wire termination that has the female connector of dilatation joint is a spherical structure, after pegging graft mutually, the termination of inner wire be positioned at male connector cavity and can be within it along the circumferential deflection of axis generation certain angle, so it is bad to neutrality to overcome in the socket two connectors, can not successfully peg graft, and peg graft reluctantly back switching performance and the relatively poor technical problem of electric conductivity, still can guarantee the two switching performance and electric conductivity after the grafting, the neutrality difference is caused can't be to a difficult problem of inserting for indivedual connectors when fundamentally having solved socket.

Embodiment

As shown in Figure 1, male connector 8 of the present utility model has a tubular outer conductor 3, be socketed in the outer conductor 3 insulator 2 inner ends for by collar extension to interior diameter reduce gradually horn-like, and the diameter of other end port is slightly less than the diameter that it has curved surface cavity 7.The axis of male connector 8 is provided with the inner wire 1 of a tubulose, and two terminations of this inner wire 1 are designed for sphere, and along inner wire 1 vertically have a dilatation joint 10, can make it in the grafting process, guarantee to have certain elasticity.

As shown in Figure 2, female connector 9 has a circular housing 6, central authorities are provided with a tubulose inner wire 4 that male connector 8 inner wires 1 are inserted in this shell 6, be coated with one deck insulator 5 again outside the inner wire 4, and a hemisphere is made in the termination of this insulator 5.In the port of shell 6, also be provided with a horn mouth.

When 9,8 pairs of yin, yang connectors were slotting, the inner wire 1 of male connector 8 inserted in the inner wire 4 of female connector 9, and inner wire 4 outer knob insulators 5 insert in the cavity 7 of male connector 8.Because the spherical termination of insulator 5 and working in coordination of male connector 8 cavitys 7, be similar to the structure of a universal joint, the horn mouth of female connector 9 ports design (referring to Fig. 3) in addition, so yin,

yang connector

9,8 is axis free deflection in the scope of certain angle relatively, automatically in looking for, 9,8 pairs of bad grafting problems of neutrality of yin, yang connector during with the solution socket.
