    Abstract: The disclosure provides a touch sensor unit. A conductive component is arranged between a pair of electrodes which are arranged inside an insulating tube, and the conductive component includes: a body section, which extends in a longitudinal direction of the insulating tube; and a convex section, which is arranged on an outer circumference of the body section, extends along the longitudinal direction of the body section, and sinks into the pair of electrodes. Short circuit or non-short circuit and so on of the electrodes can be detected by detecting the resistance value of the conductive component. Merely by inserting the conductive component into one end in the longitudinal direction of the electrodes, the pair of electrodes are electrically connected, and only the convex section sinks into the pair of electrodes, therefore the insertion load of the conductive component can be reduced, and the terminal treatment can be simplified.

  • Patent number: 10075162
    Abstract: First and second bridging portions (63a and 63b) is disposed so as to form a shock absorbing space (63c) between the sensor accommodating portion (61) and the fixing portion (62), and elastically deformed by external force, and the paired bridging portions (the shock absorbing space (63c)) is caused to function as a shock absorbing portion (63). Furthermore, the sensor accommodating portion (61) is thinner than each of the bridging portions (63a and 63b), after the sensor accommodating portion (61) is elastically deformed and a contact of a blockage is detected, the first and second bridging portions (63a and 63b) can be elastically deformed to absorb a shock. Therefore, it is possible to significantly reduce a load on the blockage in comparison with the conventional technique. Since the drive unit is reversely driven after shock absorption, it is possible to reduce the load on the drive unit and so forth, and to inhibit the occurrence of inconvenience such as burning.
