It is first-class, performance of connector can be caused to reduce, or even damage；
(3) field maintenance can not be carried out after the connector damage on teaching experiment module circuit；
(4) rapid-maintenance can not be realized after the connector damage on teaching experiment module circuit.
The content of the invention
It is an object of the invention to provide it is a kind of can live rapid-maintenance teaching experiment module circuit test interface, it is and existing
Have in technology and directly compared by method of the connector on teaching experiment module circuit as experiment test interface, the present invention is not straight
The connector being connected to test cable on teaching experiment module circuit is connect experiment, but can live rapid-maintenance by one
Adapter, experiment is connected to the test interface of teaching experiment module circuit with test cable, solves teaching experiment module electricity
On road connector damage after can not live rapid-maintenance, influence user use the problem of.
The technical proposal of the invention is realized in this way：
A kind of teaching experiment module circuit test interface, including connector and adapter, connector and adapter pass through peace
Assembling structure part is fixedly installed togather；
Wherein, in the mounting structure be used for fix connector first structure part be one carry and Luo outside connector
Set size is consistent, structural members with regular hexagon sets of holes；Being used for the second structural member of fixing adapter in mounting structure is
One carries structural member consistent with adapter connector outer diameter size, with circular sets of holes and mounting flange；
The connector draws experiment test interface from teaching experiment module circuit printed circuit board, uses mounting structure
In first structure part be enclosed on connector, and mounting structure is fixed on to the cavity of teaching experiment module circuit with screw
On；Adapter is passed through into the second structural member in mounting structure, experiment test interface is connected to, tightens in the direction of the clock, and
Adapter is tightened together with mounting structure by flange mounting hole with screw.
Alternatively, the connector is a kind of SMA-JHD connectors.
Alternatively, the adapter is a kind of SMA-KFK adapters.
The beneficial effects of the invention are as follows：
(1) switching of teaching experiment circuit test interface connector is realized；
(2) installation of teaching experiment circuit test interface connector adapter is realized；
(3) rapid-maintenance of teaching experiment circuit test interface connector adapter is realized；
(4) solve test interface connector in teaching experiment module circuit it is fragile and damage after be unable to field maintenance
Problem.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The teaching experiment module circuit test interface of the present invention realized by connector and chang-over device combination, as shown in Fig. 2
Connector 3 is a kind of SMA-JHD connectors, as shown in figure 3, adapter 7 is a kind of SMA-KFK adapters.Above-mentioned connector 3 and
Adapter 7 is fixedly installed togather by mounting structure combination, as shown in figure 4, being used to fix connector in mounting structure 4
3 part, it is one and carries, structural members 5 of with regular hexagon sets of holes consistent with Luo sets size outside SMA-JHD connectors；Peace
In assembling structure part 4 be used for fixing adapter 7 part, be one with it is consistent with SMA-KFK adapter connector external diameter sizes,
Structural member 6 with circular sets of holes and mounting flange.
The realization principle of the teaching experiment module circuit test interface of the present invention is as follows：
First, experiment is drawn from teaching experiment module circuit printed circuit board 1 with the SMA-JHD connectors 3 shown in Fig. 2
Test interface 2, obtain teaching experiment module circuit as shown in Figure 5；
Next, as shown in fig. 6, be enclosed on the structural member 5 of mounting structure 4 on connector 3, and will be installed and tied with screw
Component 4 is fixed on the cavity of teaching experiment module circuit 1；
