Description

Coaxial connector

【Technical field】

The present invention relates to be electrically connected with technical field, more particularly to a kind of moved end is sub with coaxial company for determining termination contact stabilization Connect device.

【Background technology】

In the communication equipments such as mobile phone, it usually needs coaxial connector is installed, to facilitate inspection to be arranged on the height in equipment The state or performance of frequency circuit.At present, the structure of coaxial connector approximately as：Fixed end is installed in insulating base frame and dynamic Terminal, insulating base frame outside is coated with metal shell, also, is formed with insulating base frame slotting for the center terminal of banjo The grafting space structure for entering, behind center terminal insertion grafting space, promotes moved end to leave fixed end, by the electronics of original conducting Circuit disconnects, meanwhile, moved end is contacted with center terminal, and center terminal turns into conducting state, will be come from by the center terminal Outside is led in the electric signal of electronic circuit, so as to the state and performance to circuit are realized checking.

In the prior art, above-mentioned fixed end is typically all to be contacted using one side with moved end, i.e., by moved end it is sub to It is upper to realize contacting from the side surface of side abutting contact fixed end to the lower surface realization contact of fixed terminal or by moved end, However, developing toward the direction of miniaturization along with communication equipments such as mobile phones, the appearance and size of coaxial connector is also correspondingly more next Smaller, this results in above-mentioned traditional unilateral overlap joint way of contact due to the limitation of structure space, it is impossible to ensure effectively reliable After long-acting contact, particularly long-term use, it may appear that moved end son and fixed end son between loose contact, the sub- lost its bounce in moved end, make The problems such as using the lost of life, and the mode that this unilateral overlap joint is contacted, moved end and fixed end resist and do when signal transmission is carried out Immunity is also poor.

Therefore, it is necessary to provide a kind of new coaxial connector to overcome above mentioned problem.
