Abstract: The object of the invention is to provide an electronic padlock (1), by means of which the chance of erroneous opening of the electronic padlock is reduced. The electronic padlock according to the invention comprises a body (2) and a shackle (3). The body has latch parts (4), a cam piece (5) and an electronic actuator (6). The electronic actuator (6) comprises a pivot shaft (7), which is arranged to turn the cam piece (5) to release the latch parts (4) from a locking state, and also to turn the cam piece (5) to hold the latch parts in the locking state. In the locking state, the latch parts (4) prevent the shackle (2) from being moved to open the electronic padlock (1). Between the electronic actuator (6) and cam piece (5) there is a blocking mechanism (8). The blocking mechanism connects the pivot shaft (7) of the electronic actuator (6) functionally to the cam piece (5) to turn it with the electronic actuator (6) and prevent any other turning of the cam piece (5) in relation to the body (2).

Abstract: A cam lock has a lock cylinder and a cam part connected to the lock cylinder. The cam part is turnable from a lock position to an open position when turning a key placed in the lock cylinder. The cam part comprises a spring and a flange that is arranged to receive external force towards the lock cylinder. The spring allows the movement of the cam part at the open position towards the lock cylinder as response to external force. The spring is further arranged to turn the cam part towards the lock position.
