Abstract

A sequential connecting apparatus is used with an automatic testing apparatus to enable a plurality of electronic devices for testing to be automatically connected to the testing apparatus selectively in succession, thereby enabling unattended testing of the plurality of devices.

Claims

1. A sequential connecting apparatus for testing avionics devices, comprising:

a mounting device on which a plurality of avionics devices are to be mounted in a line;

a connecting device having a connector for electrically connecting and disconnecting each of said avionics devices to and from an automatic testing apparatus for testing functions of said devices, said connecting device being drivingly mounted to said mounting device to be driven on said mounting device along the line of avionics devices; and

a system controller for causing said connecting device automatically to be driven along the line of avionics devices and to electrically connect and disconnect each of said avionics devices to and from the automatic testing apparatus selectively, in succession, and for generating a data input signal for said automatic testing apparatus in response to a request from said automatic testing apparatus.

3. A sequential connecting apparatus according to claim 1, wherein said system controller includes a memory for storing data regarding said avionics devices.

4. A sequential connecting apparatus according to claim 1, wherein said system controller includes means for checking whether a said avionics device is mounted at a predetermined position of said mounting device.

5. A sequential connecting apparatus according to claim 1, wherein said connecting device includes a test card connector for electrically connecting and disconnecting an equipment test card to and from said automatic testing apparatus.

6. A sequential connecting apparatus according to claim 5, wherein said system controller includes means for checking the presence or absence of the equipment test card.

7. A sequential connecting apparatus according to claim 1, wherein said connecting device includes positioning means for determining a positional relationship between the connector and a selected one of said avionics devices.

8. A sequential connecting apparatus according to claim 1, wherein said connecting device includes an overtorque sensor for generating a warning signal when an excess load is imparted in connecting or disconnecting a selected one of said avionics devices, and said system controller responds to the warning signal to send a signal to stop the connecting or disconnecting of said one device.

9. A sequential connecting apparatus according to claim 1, wherein said connecting device swings said connector transversely to a connecting/disconnecting movement direction of said connector when said connector is to be connected to or disconnected from a selected one of said avionics devices.

10. A sequential connecting apparatus according to claim 1, wherein said connecting device includes different types of connectors to permit the connection and disconnection of different types of avionics devices to and from said automatic testing apparatus.

22. A sequential connecting apparatus according to claim 1, including a screw-type drive which drives said connecting device on said mounting device.

2. A sequential connecting apparatus for testing avionics devices, comprising:

a mounting device on which a plurality of avionics devices are to be mounted in a line;

a connecting device having a connector for electrically connecting and disconnecting each of said avionics devices to and from an automatic testing apparatus for testing functions of said devices, said connecting device being drivingly mounted to said mounting device to be driven along the line of avionics devices;

a system controller for causing said connecting device automatically to be driven along the line of avionics devices and to electrically connect and disconnect each of said avionics devices to and from said automatic testing apparatus selectively, in succession, and for generating a data input signal for said automatic testing apparatus in response to a request from said automatic testing apparatus;

a display interface for converting a message signal from said automatic testing apparatus to a signal decodable by said system controller; and

a keyboard interface for converting the data input signal from said system controller to a signal decodable by said automatic testing apparatus.

23. A sequential connecting apparatus according to claim 2, including a screw-type drive which drives said connecting device on said mounting device.

11. A sequential connecting apparatus for testing avionics devices, comprising:

a mounting device adapted to receive a plurality of avionics devices to be tested by an automatic testing apparatus; and

a connecting device electrically connectable to each of said avionics devices, selectively, to connect said avionics devices to the automatic testing apparatus, said connecting device being automatically drivable on said mounting device, from one of said avionics devices to another, to connect said avionics devices to the automatic testing apparatus automatically, in succession.

12. A sequential connecting apparatus according to claim 11, further comprising a controller for controlling the automatic connection of said connecting device to said avionics devices and outputting a data signal corresponding to the connected avionics device.

13. A sequential connecting apparatus according to claim 11, wherein said connecting device includes connectors for connecting to different types of avionics devices.

14. A sequential connecting apparatus according to claim 11, wherein said connecting device includes a plug-in type connector for connecting to said avionics devices.

15. A sequential connecting apparatus according to claim 14, wherein said connecting device swings said connector transversely to a plug-in movement direction when said connector is plugged or unplugged to or from one of said avionics devices.

24. A sequential connecting apparatus according to claim 11, including a screw-type drive which drives said connecting device on said mounting device.
