Patent attributes
A quick-detachable terminal seat includes a main body and a pull rod. The terminal seat is mounted in a casing of a controller which is provided with two notches and locking slots on its periphery. The pull rod has two hooks engaged with the locking slots. The pull rod is provided with two inclined surfaces at locations corresponding to the notches respectively. When the pull rod is pulled out of the main body with the hooks being disengaged from the locking slots, the two inclined surfaces are moved out of the two notches respectively, so that the terminal seat can move upwardly with respect to the casing. In this way, the terminal seat can be detached there from quickly with less labor, or it can be mounted in the casing easily without additional tools. The present invention further provides a programmable logic controller having the terminal seat.
