A movable insulator includes a plurality of second fixing grooves disposed along the arrangement direction. The contacts each include a first base portion supported by a corresponding one of the first fixing grooves, a second base portion supported by a corresponding one of the second fixing grooves, a first arm portion connected to the first base portion and disposed between two corresponding adjacent ones of the partition walls, and a second arm portion connected to the first arm portion and the second base portion. A largest width of the first arm portion is smaller than a largest width of the second arm portion. ## Claims ### Claim 1 A connector comprising: a fixed insulator; a movable insulator that is disposed on an inner side of the fixed insulator and is movable relative to the fixed insulator; and a plurality of contacts attached to the fixed insulator and the movable insulator, wherein the fixed insulator comprises a plurality of first fixing grooves disposed along an arrangement direction in which the plurality of contacts are arranged, and partition walls each disposed between two corresponding adjacent ones of the contacts, the movable insulator comprises a plurality of second fixing grooves disposed along the arrangement direction, the contacts each comprise a first base portion supported by a corresponding one of the first fixing grooves, a second base portion supported by a corresponding one of the second fixing grooves, a first arm portion connected to the first base portion and disposed between two corresponding adjacent ones of the partition walls, and a second arm portion connected to the first arm portion and the second base portion, and a largest width of the first arm portion is smaller than a largest width of the second arm portion. ### Claim 2 (depends on 1) The connector according to claim 1, wherein the second arm portion is disposed closer to the second base portion than the partition wall is. ### Claim 3 (depends on 1) The connector according to claim 1, wherein a thickness direction of the contacts is the arrangement direction. ### Claim 4 (depends on 1) The connector according to claim 1, wherein at least one of the first arm portion and the second arm portion comprises a linear portion that is linear and a bent portion that is bent. ### Claim 5 (depends on 1) The connector according to claim 1, wherein the first arm portion comprises a first slit that is a slit formed through the first arm portion in the arrangement direction, the second arm portion comprises a second slit that is a slit formed through the second arm portion in the arrangement direction, and a largest width of the first slit is smaller than a largest width of the second slit. ### Claim 6 (depends on 5) The connector according to claim 5, wherein one of the first slit and one of the second slit are provided. ### Claim 7 (depends on 6) The connector according to claim 6, wherein a width of a portion of the first arm portion on each of both sides of the first slit is equal to a width of a portion of the second arm portion on each of both sides of the second slit. ### Claim 8 (depends on 6) The connector according to claim 6, wherein the second arm portion comprises a first bent portion that is convex toward the second base portion and a second bent portion that is convex toward the first base portion. ### Claim 9 (depends on 8) The connector according to claim 8, wherein a width of the second slit is largest at the second bent portion. ### Claim 10 (depends on 8) The connector according to claim 8, wherein the second arm portion comprises an inclined inner wall that is inclined to reduce a width of the second slit toward the second base portion, between the second base portion and the second bent portion. ### Claim 11 (depends on 1) The connector according to claim 1, wherein the partition walls each comprise an inclined surface inclining away from the second arm portion as the inclined surface gets closer to a virtual plane passing through bottom surfaces of a plurality of the first base portions. ### Claim 12 (depends on 1) An electronic device comprising the connector according to claim 1.
