Abstract

The utility model relates to a radio frequency coaxial connector which comprises spring shims arranged outward in the connecting port of a female head in sequence, at least a pair of contact heads shaped by punching beryllium bronze and a retaining ring arranged on the connecting port of the female head; wherein an annular matching part tightly matched with the inner wall of the connecting port ofthe female head is arranged at the bottom of the contact heads. Because the contact heads are pressed into a casing in a close fit way during the assembly process and compress the spring shims simultaneously, the reliability of the contact between the inner conductor and the outer conductor of the connector can be guaranteed, thereby ensuring the stability of signal transmission of the entire system. The contact heads are provided with bevel surfaces in the contact position, thereby ensuring the coaxiality of the connector in the blind insert state and during the mechanical vibration process.

Description

Radio frequency (RF) coaxial connector

Technical field

The utility model relates to the communication distribution block, concrete a kind of radio frequency (RF) coaxial connector.

Background technology

Existing radio frequency (RF) coaxial connector comprises: male head and female, the inwall of the connectivity port of female are provided with and are used for the contact head 1 (as Fig. 3) that matches with the outer wall of male connectivity port.

Put into the inwall of the connectivity port of female after the contact head 1 employing beryllium bronze band punch forming, promptly utilize the cannelure of female housing to fix, in the female transportation, contact head 1 easily drops out the female housing; Or plug in the use each other with female or under the condition of vibrations at the male head of connector, male drop out easily or contact with female unreliable.

How avoiding above-mentioned situation occurring, is the technical barrier that those skilled in the art will solve.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple in structure, transportation or reliability radio frequency (RF) coaxial connector preferably when using.

For solving the problems of the technologies described above, the utility model provides a kind of radio frequency (RF) coaxial connector, comprising: from inside to outside be located at the spring shim in the connectivity port of female successively and adopt stamping forming at least one pair of contact head of beryllium-bronze and be located at back-up ring on the connectivity port of female; The afterbody of contact head has the friction tight auxiliary section of connectivity port inwall with female.

Further, described back-up ring is fixed on the connectivity port of female by closing in riveted joint mode.

Further, the auxiliary section and the spring shim Elastic Contact of contact head bottom.

Further, described contact head axially is symmetrically distributed, and has the bend to the central shaft bending on the contact head.

The utlity model has positive effect: in (1) radio frequency (RF) coaxial connector of the present utility model, contact head adopts the beryllium-bronze punch forming, and spring shim adopts the machine work aftershaping, adopts tight fit to be pressed in the connectivity port of female in the assembling process.Because contact head adopts tight fit to be pressed into housing in assembling process, the while is the holddown spring pad again, guarantees the reliability of the internal and external conductor contact of connector.Thereby guarantee that whole system has stability in the signal transmission.(2) when female, male head cooperation, contact head has increased the inclined-plane in the contact site be described bend, guaranteed the axiality of connector under blind slotting state.Therefore, radio frequency (RF) coaxial connector of the present utility model has simple in structure, transportation or reliability advantage preferably when using.

Description of drawings

For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein

Fig. 1 is the cross-sectional view at the female interface of the radio frequency (RF) coaxial connector among the embodiment;

Fig. 2 is the sectional structure chart at the female of the radio frequency (RF) coaxial connector among the embodiment and male head interface when cooperating;

Fig. 3 is the cross-sectional view at the female interface of radio frequency (RF) coaxial connector of the prior art.

Embodiment

See Fig. 1-2, the radio frequency (RF) coaxial connector of present embodiment comprises: from inside to outside be located at the spring shim 2 in the connectivity port of female b successively and adopt beryllium-bronze stamping forming at least one pair of be used for back-up ring 3 on contact head 1 that matches with a hero a and the connectivity port of being located at female b; The bottom of contact head 1 has the friction tight auxiliary section 1-1 of the connectivity port inwall with female b of annular.

Described back-up ring 3 is fixed on the connectivity port of female b by closing in riveted joint mode.

The auxiliary section 1-1 of contact head 1 bottom and spring shim 2 Elastic Contact.

Described contact head 1 axially is symmetrically distributed, and has the bend 1-2 to the central shaft bending on the contact head 1.

Obviously, the foregoing description only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection range of the present utility model.
