Position detection sensor and manipulator
First Claim
1. A position detection sensor comprising:
- a linear member;
a conductive portion and an insulating portion provided in an outer periphery of the linear member, the conductive portion and the insulating portion being arranged side by side in a direction of an axis of the linear member;
a support member having insulating properties, the support member being provided so as to be capable of being relatively advanced or retracted in the direction of the axis with respect to the conductive portion and the insulating portion;
a conductive contact member attached to the support member, the contact member being configured such that a distal end of the contact member comes in contact with outer surfaces of the conductive portion and the insulating portion by a biasing force toward the outer surfaces of the conductive portion and the insulating portion;
a first biasing member configured to generate the biasing force;
a second biasing member configured to generate the biasing force,a holding member configured to hold the first biasing member and the second biasing member; and
a fixing portion configured to fix the first biasing member and the second biasing member to the holding member, whereinthe first biasing member and the second biasing member are attached to the support member together with the holding member,the contact member includes a first contact member attached to the first biasing member and a second contact member attached to the second biasing member,the conductive portion is provided in plural numbers, and the insulating portion is provided in plural numbers,each of the plurality of conductive portions and each of the plurality of insulating portions are alternately arranged in the direction of the axis, andthe holding member holds the first biasing member and the second biasing member such that a distance in the direction of the axis between a position in which the second contact member comes in contact with the plurality of conductive portions or the plurality of insulating portions and a position in which the first contact member comes in contact with the plurality of conductive portions or the plurality of insulating portions becomes a predetermined distance.
