Embodiment
Combine accompanying drawing that the utility model is done further explain through embodiment below.
Embodiment one:
Please refer to Fig. 2 and Fig. 3; Coaxial adatpter in this example is made up of outer conductor 21 and the inner wires 24 that are arranged at outer conductor 21 inside; Wherein an end of inner wire 24 stretches out said outer conductor 21 and links to each other with a tested hard connector; The other end cooperates with the AN connector joint 22 that outer conductor 21 other ends are provided with, and forms the inner core of AN connector joint 22, and the AN connector joint 22 that is provided with on the outer conductor 21 is used for cooperating with another tested hard connector.Inner wire 24 can be fixed on outer conductor 21 inside through Supporting Media in this example, can use annular knurl, hangnail technology that inner wire 24 is fixed on outer conductor 21 inside, to prevent that inner wire 24 is in outer conductor 21 inner rollings, rotation etc.
The shape of outer conductor 21 cross sections can be selected as the case may be; As can be squarely, selecting outer conductor 21 in the circles etc., this example be the pipeline of circle; The shape of the inner wire 24 of its set inside also can be selected according to actual conditions; Inner wire 24 in this example is chosen as columniform shaft-like, and the part 241 that inner wire 24 stretches out outer conductor 21 is used for cooperating with hard connector, and the mode of its cooperation can have multiple; Can be smooth cylinder-shaped joint like extension 241 (being joint 241), directly insert hard connector during use and cooperate with it.For the reliability that guarantees to connect; Joint 241 parts in this example can be provided with at least one groove and/or the boss that cooperates with hard connector; Make joint 241 engaged, the outer conductor 21 and the outer conductor of hard connector are combined closely, so the joint in this example 241 is reliable with being connected of hard connector with hard connector; Can stablize the conduction radiofrequency signal, guarantee the effect of test.
Preferably; Joint 241 in this example is an inner wire reach nipple; Its screw thread is complementary with the screw thread of the inner wire of hard connector, makes mutual stranded connection of inner wire of inner wire reach nipple and hard connector, has further guaranteed the reliability of connection.Preferably, the screw thread in this example is a standard thread, generally can use the M3 standard thread.
AN connector joint 22 in this example can be preferably joints commonly used such as accurate joint of N leader or the accurate joint of SMA leader; Specifically can select according to the actual requirements; Inner wire reach nipple in this example can be preferably beryllium-bronze or tin bronze nipple, and its electroplate or gold-plated, to guarantee effective contact; And then effective transmission of assurance signal, the outer conductor 21 in this example can be preferably brass or plating ternary alloy three-partalloy outer conductor.
