Device for coding a first connection partner and a second connection partner of a bayonet catch and device set

摘要

The invention relates to a device for coding a first connection partner (12) and a second connection partner (14) of a bayonet lock, the first connection partner (12) having at least two locking arms (16, 18, 20) for locking the connection and being arranged on a fluid line adapter and wherein the second connection partner (14) has a flange ring (22) for passing through the first locking partner (12) with a number of recesses (24, 26, 28) corresponding to the number of locking arms (16, 18, 20) for passing through the locking arms (16, 18, 20) and is arranged on an adapter receptacle, a first locking arm (16) having a different geometry than the further locking arms (18, 20), wherein a first recess (24) assigned to the first locking arm (16) a matching geometry for positioning the first connection partner (12) and the second connection partner (14) in a vo r-defined position, and the further recesses (26, 28) have a different geometry that does not match the first locking arm (16), and wherein the device (10) further has a mechanical coding device, the coding device having a first coding partner (42) on the first connection partner (12) and a second coding partner (44) on the second connection partner (14), the first coding partner (42) and the second coding partner (44) being aligned with one another if the first connection partner (12) and the second connection partner (14) are arranged in a predefined position to one another and a connection is effected via the bayonet lock. The invention thus provides an improved device (10) for coding a first connection partner and a second connection partner of a bayonet catch, which can be handled more effectively. This avoids mixing up the connection partners of different devices (10). A stop can be used to indicate to a user that the first connection partner and the second connection partner are mounted and locked in the correct position.
