  • Patent number: 10370878
    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.
