Description

Break out box {Break out box}

The present invention relates to a breakout box, and more particularly, to a breakout box capable of measuring isolation without a jumper.

In general, a Break Out Box (B0B) is used to explore electrical interfaces between units constituting satellites, electrical signal confirmation or failure, etc. in satellite assembly or testing. do. For example, the breakout box is connected between units to be inspected, and the connection state of a signal line connected to a specific test point is checked using a plurality of test points provided in the breakout box, or the signal level at the corresponding test point. It can be used to measure the magnitude of or voltage.

After the breakout box is inserted between the connection harnesses of the units to be verified, the breakout box can perform the necessary tasks. For example, it is possible to check the connection diagram of specific lines using specific points of the BOB, or to measure electrical signal waveforms or voltage/current/resistance values at those points. In addition, swapping of specific pins and artificial opening (opening of connection lines) are possible for debugging purposes.

Before using manufactured harnesses, breakout boxes, etc., insulation tests must be performed to check for short circuits between signal lines. In order to improve the efficiency of the insulation test, a series of tasks for tying various signal lines are required, which is very cumbersome and confusing because banana cable type jumpers are usually used.

The plurality of switches may be single pole triple through (SPTT) switches.

The interconnection may include a first conductive wire and a second conductive wire.

The switching unit selectively connects or opens the first pin to the second pin and the first conductive wire, and selectively connects or opens the second pin to the first pin and the second conductive wire. can make it

The switching unit may open an insulation test target pin among the plurality of first pins, connect all remaining pins of the plurality of first pins to the first conductive wire, and test insulation among the plurality of second pins.
