Pressure-sensitive sensor, connector and combining structure thereof
First Claim
1. A pressure-sensitive sensor comprising:
- a tube member having a hollow portion defined by an inner wall thereof and comprising a flexible material, the tube member extending in a predetermined direction;
a first belt-like electrode disposed on an upper side of the hollow portion of the tube member and extending in the predetermined direction;
a second belt-like electrode disposed on a lower side of the hollow portion of the tube member so as to oppose the first belt-like electrode and so as to extend in the predetermined direction, the first belt-like electrode and the second belt-like electrode being configured to contact each other, thereby ensuring conductivity when the pressure-sensitive sensor is pressed; and
a contact adjusting portion provided on the inner wall of the tube member for adjusting contact between the first belt-like electrode and the second belt-like electrode, the contact adjusting portion comprising a concave portion provided in a side face of the inner wall of the tube member between the first belt-like electrode and the second belt-like electrode.

Abstract
A pressure-sensitive sensor is provided with a tube member having a hollow portion defined by an inner wall and made of flexible material, a first belt-like electrode disposed on an upper side of the tube member in the tube member and a second belt-like electrode disposed on a lower side of the hollow portion in the tube member so as to oppose the first belt-like electrode. When the pressure-sensitive sensor is pressed, the first belt-like electrode and the second belt-like electrode are capable of contacting each other so as to ensure conductivity. Further the pressure-sensitive sensor has a contact adjusting portion provided on an inner wall of the tube member and for adjusting a contact between the first belt-like electrode and the second belt-like electrode. Additionally, a connector capable of being combined with such a pressure-sensitive sensor is also disclosed.
