A contact device for receiving a plug end includes a first contact, which has a first coupling end and a first contact end, and a second contact, which has a second coupling end and a second contact end. The coupling ends are configured to electrically couple the respective contact to a receiving device, and the contact ends are configured to electrically connect the respective contact to a contact element of the plug end. The shortest distance between the first coupling end and the first contact end is not equal to the shortest distance between the second coupling end and the second contact end. The total length of the first contact is equal to, or is within a predetermined tolerance from, the total length of the second contact.
