Title:
PRESSURE SENSOR AND PRODUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/004400
Kind Code:
A1
Abstract:
To improve work efficiency and realize a low-cost structure without electrically
damaging the electronic components of a pressure sensor. Contact pins (27-1
to 3) connected via a binding wire material to a pressure detecting sensor chip
are mounted to a resin body (12). The ends of electric wires (50-1 to 3) connected
with an external apparatus are semi-stripped and simultaneously ultrasonic-welded
to three contact pins (27-1 to 3) using an ultrasonic-welding machine. Partition
plates (34) are provided between the contact pins to prevent short-circuiting
between electric wires. Each contact pin (27-1 to 3) is provided with a hole (38)
for reducing its rigidity to prevent the connection of spot-welded contact pins
and a binding wire material from being disconnected at ultrasonic-welding.
After the electric wires (50-1 to 3) and the contact pins (27-1 to 3) are ultrasonic-welded,
a resin case (40) is placed over the resin body (12) to allow a sealant (42) to poured
in.
