Currently, the BMA and SMP series are the main radio frequency coaxial connectors capable of realizing the blind plugging function.
The advantages and disadvantages of these two series are different: the BMA series radio frequency coaxial connector crown spring type locking structure is reliable in contact, the frequency range is 0-18 GHz, and the highest working frequency of errors such as actual processing precision and the like is considered to be about 12 GHz; the highest working frequency of the SMP series is about 40GHz, but the locking structure adopts a spring claw type structure, so that the connection is easy to fail after multiple plugging and unplugging, and the electrical performance is influenced. In view of the advantages and the disadvantages of the two radio frequency connectors, the blind-mate radio frequency coaxial connector with high working frequency and high reliability is designed.
The defects in the prior art are as follows: the locking structure adopts a spring claw type structure, so that the connection is easy to lose efficacy after multiple plugging and unplugging, and the electrical performance is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving among the prior art locking structure and adopting bullet claw formula structure, connect the inefficacy easily after the plug many times, influence the shortcoming of electrical property, and the blind plug radio frequency coaxial connector of a high operating frequency, high reliability that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the blind-mate radio frequency coaxial connector with high working frequency and high reliability comprises a plug and a socket, wherein a positioning rod is arranged at the front end of the plug, a positioning groove is formed in the left side of the socket, the positioning rod is matched with the positioning groove, and a shielding spring is arranged in the positioning groove.
Preferably, the positioning rod is of a hollow structure, the inner side of the positioning rod is provided with a positioning needle, a connecting cylinder is arranged in the socket, and the connecting cylinder is matched with the inner side of the positioning rod.
Preferably, a needle groove is formed in the inner side of the connecting cylinder, and the positioning needle is matched with the needle groove.
Preferably, the outer side of the plug is sleeved with a sealing ring.
The utility model discloses in, a blind plug radio frequency coaxial connector's of high operating frequency, high reliability beneficial effect:
the structure of the utility model is compact, the specification and size of the inserting end face and the contact element refer to SMP series, and the requirement of working frequency 40GHz can be met; the unique structural characteristics of the shielding spring provide good mechanical properties for the connector, can ensure that various performance indexes meet requirements after 5000 times of plugging and unplugging, and has high reliability. Compared with other elastic connection radio frequency connectors, the blind plugging performance is softer, the mechanical wear is smaller, and the opposite plugging floating amount is larger.
