Electromechanical lock cylinder
First Claim
1. An electromechanical lock cylinder, having a first cylinder half adapted to be arranged on the outside of a door, having a key channel for a safety key and a second cylinder half to be arranged on the inside of the door, having a rotary knob rotor, which is connected to a rotary knob, having tumblers, which are arranged in the first cylinder half and which are to be positioned by the safety key in order to enable rotation, having electronics arranged in the rotary knob for the purpose of driving a blocking apparatus, which can block the rotation, wherein the rotary knob with the electronics arranged therein forms a unit which is mounted detachably so that it can be plugged on an extension, which protrudes on a housing, of the rotary knob rotor, wherein the electronics are connected to the housing of the second cylinder half by means of a plug-in connection.

Abstract
The invention relates to an electromechanical lock cylinder, comprising a first cylinder half (2), arranged on the outside of the door, with a key passage (8) for a security key (44) and a second cylinder half (3), arranged on the inside of the door, with a rotating knob rotor (4). Tumblers in the first cylinder half (2) are arranged for rotational release by a security key (44). An electronic device (17) is arranged in the rotating knob (24) for control of a locking device (43). The rotating knob (24) forms a unit with the electronic device (17) arranged therein, detachably mounted on an extension (4a) of the rotating knob rotor (4), projecting past the housing (6). The rotating knob rotor (24) may be adjusted for length by means of an exchangeable adapter (18a to 18c).
