Abstract

Disclosed is a method whereby the battery connector improved by changing a little shape protects the short circuit more easily and steadily than a usual one. This is because it is always very troublesome from the safety point of view to insulate the plug contacts of the battery connector from the other components on the circuit board placement.

Battery Connector Short Circuit Protection by Mechanical Change

      Disclosed is a method whereby the battery connector improved by
changing a little shape protects the short circuit more easily and
steadily than a usual one.  This is because it is always very
troublesome from the safety point of view to insulate the plug
contacts of the battery connector from the other components on the
circuit board placement.

      Fig. 1 shows an example of a usual battery connector plug.  In
the case of placing this connector on the circuit board, since the
battery connectors which the large electric current goes through have
the bare parts electrically between the connector housing and the
circuit board, the insulation of the bare part is required to be very
carefully designed to protect the short circuit on the safety design
point of view, such as securing enough space between the bare parts
and the other components.  Otherwise, the insulation sheet or glue
that has  the long term reliability against the humidity, dew,
heating, vibration,  etc., must cover the bare parts.  If a short
circuit should happen, the  damage of the circuit board would not be
little because there is a possibility that over ten Ampere electric
current goes through the battery power line in a moment of the short
circuit.

      Fig. 2 shows the improved battery connector plug.  The
connector housing is covering the bare plug contacts so that the
large electric current goes through, excep...
