Push rod lock for a switchgear cabinet housing, corresponding arrangement, and corresponding method

A method for mounting a door lock plate on a switch cabinet door, wherein the door lock plate, when mounted on the switch cabinet door, is fixed via a mushroom pin connection by vertically displacing the door lock plate relative to the switch cabinet door, the method comprising:

• positioning an actuating element of the door lock plate in a first open position or in a first intermediate position between the first open position and a closed position of the actuating element;
• positioning a push rod, which is adjustable in a vertical direction between a second open position and a second closed position at the inner side of the switch cabinet door, in the second closed position or a second intermediate position between the second open position and the second closed position of the push rod;
• placing the door lock plate with a vertical offset to a final mounting position on the switch cabinet door, wherein an adjusting element of the actuating element of the door lock plate is brought into engagement with a coupling piece of the push rod, and wherein furthermore at least one mushroom pin of the door lock plate is inserted into a key opening of the switch cabinet door;
• if the push rod is not arranged in the closed position, transferring the actuating element proportionately from the first open position or the first intermediate position in direction of the closed position until the push rod is arranged in the second closed position;
• and
• when the push rod is arranged in the closed position, transferring the actuating element into the closed position and thereby displacing the door lock plate relative to the switch cabinet door until the door lock plate is arranged in an end position in which the mushroom pin connection assumes a locking position.
