3) Prevention of problems during use
(1)The connectors have a simple locking structure, but make sure to consider
preventive measures against the detachment of mated connectors during
practical use.
- Make sure to eliminate any gaps between the casing and board.
- We recommend that the holding force is set greater than the insertion force of
the connector.
- Select an appropriate cushioning material with a suitable shape and dimensions,
and hold down the
center, it may cause detachment of mated connectors.)
(2)If the board is insufficiently fixed as in the following drawing, the inertial
load applied to the connector may damage it. Pay attention to the following
points.

When an impact such as dropping as shown in the
drawing is applied:
(1) If both boards are not sufficiently fixed,
the connector will be damaged due to the
impact applied to the connector.
(2) In particular, if there is no gap between
the casing and sub-board (A<B), the sub-
board side will hit the casing wall first.
This impact may damage the connector.
<Preventive measures>
Securely fix both the motherboard and sub-board.
(1) Fixing motherboard
(Prevents inertial movement by drop impact
by fixing the side with a greater mass.)
(2) Hold down the sub-board to prevent it from
moving using a rubber cushioning material,
etc.
(3) It is safer if board gaps are set to AB so as
to prevent shearing damage on deviation of
the board by impact.
