1. An industrial input/output device with movable connector, comprising:a first housing, having a first connector through hole, a first concave portion, a moving-link setting portion, and a plurality of moving guides on an inner surface thereof;
a second housing, assembled with the first housing, and having an accommodation space, a second connector through hole, and a second concave portion, wherein a position of the second connector through hole corresponds to that of the first connector through hole;
a circuit board, disposed in the accommodation space, and provided with a second connector, which is exposed to the second housing through the second connector through hole when the circuit board is disposed in the accommodation space;
a moving link, set on the first housing by passing through the moving-link setting portion, and moved relative to the first housing by the moving-link setting portion and the plurality of moving guides, and having a connector setting portion, which has two sets of guiding movement grooves provided on both sides thereof, and a connecting through hole, which is provided at a bottom thereof; and
a first connector, having setting members, a number and positions of which correspond to those of the guiding movement grooves, wherein the setting members are disposed in the guiding movement grooves corresponding thereto to make the first connector be disposed in the connector setting portion, and the first connector is exposed to the first housing when the moving link is set on the first housing by passing through the moving-link setting portion, and the first connector electrically connects to the circuit board through the connecting through hole;
wherein the moving link is disposed on the first housing, the second housing and the first housing are assembled with each other as a device housing, the first concave portion and the second concave portion form a cavity, a first operation end of the moving link is disposed to the cavity, and a second operation end of the moving link is disposed to the moving-link setting portion.
