In this novel a kind of embodiment, the end that said inner wire stretches out said outer conductor is to be provided with at least one groove or/and the joint of boss.

In this novel a kind of embodiment, the end that said inner wire stretches out said outer conductor is an inner wire reach nipple.

In this novel a kind of embodiment, said AN connector joint is accurate joint of N leader or the accurate joint of SMA leader.

In this novel a kind of embodiment, said screw thread is a standard thread.

In this novel a kind of embodiment, said inner wire reach nipple is beryllium-bronze or tin bronze nipple.

In this novel a kind of embodiment, said inner wire reach nipple is electroplate or gold-plated joint.

In this novel a kind of embodiment, said outer conductor is brass or plating ternary alloy three-partalloy outer conductor.

In this novel a kind of embodiment, also be provided with handle on the said outer conductor.

In this novel a kind of embodiment, the end that said outer conductor is provided with inner wire reach nipple also is provided with connecting groove.

The beneficial effect of the utility model is: this novel coaxial adatpter that provides is made up of the outer conductor inner wire inner with being arranged at outer conductor; One end of inner wire stretches out said outer conductor and is connected with a tested hard connector, and the other end constitutes the inner core of the AN connector joint that is provided with on the said outer conductor.Use directly dismountable being connected between two connectors to be tested of this novel adapter that provides, do not need special PCB circuit switch plate, installation, convenient disassembly, it is little to take up room, not easy to wear, long service life.

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.

For assemble, convenient disassembly; Also handle 23 can be set on outer conductor 21 in this example, handle 23 be provided with in the middle of can be the through hole that is complementary with outer conductor 2 disk, or be polygonal pan, as can be four or six or octagonal dish; To improve application of force moment, be convenient to assembling and dismounting.

Embodiment two:

See also Fig. 3 and Fig. 4; Adapter in this example is on outer conductor 21, also to be provided with connecting groove 25 with respect to the adapter among the embodiment one; Connecting groove 25 be used for hard connector 26 on boss 261 closely cooperate, during connection, boss 261 is stuck close in the connecting groove 25; Play better shield effectiveness, further guaranteed the reliability that coaxial connector is connected with the hard connector that is attached thereto.

Can know that to sum up the coaxial connector volume in this example is little, occupation space is few, with hard connector be connected and dismantle simple, convenient, connect reliable, when having improved the efficient of test, the quality of the test that also guarantees.

Above content is the further explain that combines concrete execution mode that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
