Description
Technical field
The utility model belongs to radio frequency (RF) coaxial connector technical field, is specifically related to a kind of SMA type radio frequency (RF) coaxial connector with new Joining Structure.
Background technology
Conventional SMA type connector adopts welded type method when connecting diameter semi-rigid cable, but easily occurs rosin joint phenomenon owing to welding, and is difficult to the defective item of rejecting rosin joint phenomenon by naked eyes.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of SMA type radio frequency (RF) coaxial connector with new Joining Structure, the semi-rigid cable that diameter is 3.6 millimeters can be connected, be connected and fixed by cable and connector press-fit method, avoid the shortcoming that traditional welded type exists.
For achieving the above object, the utility model by the following technical solutions:
A kind of SMA type radio frequency (RF) coaxial connector with new Joining Structure, comprise the first shell 3, the outer border of described first shell 3 is provided with the first housing boss 3-1, swivel nut 1 is socket-connected by the first housing boss 3-1 of its boss 1-1 and the first shell 3, semi-rigid cable 5 is inserted in the first shell 3, the heart yearn of semi-rigid cable 5 is as the inner wire of described connector, second housing 4 is press-fitted to outside the first shell 3, semi-rigid cable 5 is fixed by the distortion that is press-fitted of second housing 4 and the first shell 3, described second housing 4 is with second housing boss 4-1, the boss 1-1 of described swivel nut 1 is socketed between the first housing boss 3-1 of the first shell 3 and the second housing boss 4-1 of second housing 4, the afterbody housing of described first shell 3 one end has yi word pattern groove 3-2, with internal thread on the inwall of described first shell 3.
The endoporus of described second housing 4 is taper hole, is convenient to be press-fitted with the first shell 3.
First housing boss 3-1 of described first shell 3 has sealing ring 2 away from one end cover of the boss 1-1 of swivel nut 1.
The conductor employing external diameter of described semi-rigid cable 5 is 3.6mm, wall thickness is the brass tube of 0.3mm.
Compared to the prior art, tool has the following advantages the utility model:
1, because the utility model connector inner wire is substituted by the heart yearn of semi-rigid cable 5, avoid inner wire and cable core to be welded by welded type method and occur rosin joint phenomenon, cut down finished cost simultaneously.
2, semi-rigid cable 5 to insert in the first shell 3 and is press-fitted the fixing semi-rigid cable 5 of distortion by the first shell 3 and second housing 4, the afterbody housing of simultaneously first shell 3 one end has yi word pattern groove 3-2, with internal thread on the inwall of the first shell 3, can effectively prevent cable from rotating.
3, the boss 1-1 of swivel nut 1 is arranged between shell 3 and shell 4, avoids the coming off of causing by the snap ring connection of routine.
4, the bore design of second housing 4 is taper hole, is convenient to be press-fitted with the first shell 3, improves the reliability of attaching.
In sum, the utility model ensure that the stability after semi-rigid cable and connector attaching and reliability, avoids the rosin joint phenomenon generation that traditional welded type method causes, improves rate of finished products and the operating efficiency of connector.And connector dimensional structure is less, be conducive to the installation in less space.The utility model is mainly used in the national defence key projects such as Aeronautics and Astronautics, electronics, boats and ships, weapons.Also can be widely used in the communication of high reliability, wireless device and the technical field such as instrument and automatic control.
