Radio-frequency module or radio-frequency module are led all without inserting by available circuit plate by circuit board or circuit board to leading in radio-frequency module adapter, it is easy to damage adapter inner wire.
The adapter of the centre of radio-frequency module adapter all can at random be plugged together by existing available circuit plate by circuit board or circuit board by radio-frequency module or radio-frequency module with the socket at two ends, causes two ends to have not matching area to be unfavorable for impedance matching thus reducing radio frequency electric property (increasing voltage standing wave ratio).
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of permission larger axis to side-play amount, and has the radio frequency (RF) coaxial connector of good radio frequency electrical resistance.Solve the adapter inner wire when plugging together and insert bad problem.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that a kind of radio frequency (RF) coaxial connector, and including body, body includes the first socket and the second socket and connects both adapters；First socket includes the first outer conductor, the first center conductor and is located at the first insulator between the two；Adapter includes the second outer conductor, the second center conductor and is located at the second insulator between the two；Second socket includes the 3rd outer conductor, the 3rd center conductor and is located at the 3rd insulator between the two, it is characterized in that:
A. the first outer conductor contact surface of described first socket is inner circular cylinder, and the first center conductor contact surface is external cylindrical surface, and the second center conductor end is T-shaped for being with elastic external shape, and inner openings is bowl-mouth shape；
B. 5 ends of the second outer conductor of described adapter and the end of 6 ends are and have elasticity and be provided with the fixture block that radial belt salient point is tongue shape；
3rd outer conductor contact surface of described second socket be inner circular cylinder and bottom with radial slot, the 3rd center conductor contact surface is inner circular cylinder；
5 ends of adapter are plugged in the first socket, and the first outer conductor on 5 ends of the second outer conductor of 5 ends of adapter and the first socket connects, 5 ends of the second center conductor and the first center conductor connection on the first socket；
6 ends of adapter are plugged in the second socket, and the 3rd outer conductor on 6 ends of the second outer conductor of 6 ends of adapter and the second socket connects, 6 ends of the second center conductor and the 3rd center conductor connection on the second socket.
The effect of the present invention: owing to being provided with the inner wire of T-shaped in the inside of adapter, thus adapter from form different resistance region in the engaging zones of socket: when connected device pitch has very big axial tolerance, the join domain place at adapter there will be bigger the air gap, thus forming high impedance areas；And the end region of adapter forms Low ESR region, the design of socket shoulder also forms a Low ESR region, other region is normal impedance region, such high impedance areas and Low ESR region can form impedance complementation, thus reducing the high impedance areas harmful effect to connector performance, improve the radio frequency electric property of product.Therefore, the radio frequency (RF) coaxial connector of the present invention compared with prior art can allow bigger axial offset (± 1mm), reduce the amount of the impedance mismatch that linkage interface place is caused by the air gap, there is good radio frequency electric property in frequency 0 to 6Ghz.Protection inner wire is not inserted bad by adapter inner wire such as the rim of a bowl.Socket 4 only coordinates the impedance matching that ensure that a-quadrant to reach the radio frequency electric property of excellence with 6 ends of adapter 3.
