Abstract

A transponder includes an integrated circuit (1) and an antenna (5) which is electrically connected to the integrated circuit (1) in a removable manner, the removable electrical connection including at least one intermediate connection element (4). The removable connection, together with the intermediate connection element (4) between the antenna (5) and the integrated circuit (1), can be used to divide the transponder into two parts. Moreover, the intermediate connection element (4) can also be used, in one variant, to reinforce mechanically at least one part of the contact elements (40), while facilitating the precise fixing of the contact elements to the corresponding element of the object to be marked.

Claims

1. A transponder comprising:

an integrated circuit (1); and

an antenna (5) electrically connected in a detachable manner to said integrated circuit (1) via a detachable electrical connection,

wherein said detachable electrical connection comprises at least one intermediate connecting element (4),

the at least one intermediate connecting element is separate from the integrated circuit,

wherein said intermediate connecting element (4) guides positioning of at least one portion of said detachable contacts (40) by fastening elements (41),

wherein said intermediate connecting element consists of a printed circuit (4), said at least one portion of said detachable contacts consisting of contact zones (40) on the first surface of said printed circuit (4),

wherein the fasting elements are mounting holes, and

said printed circuit (4) comprises mounting holes, the relative position of said mounting holes relative to said at least one portion of said detachable contacts (40) being predetermined with precision.

2. The transponder according to claim 1, wherein said antenna (5) is electrically connected to said integrated circuit (1) so that said antenna (5) is movable relative to said integrated circuit (1) without interrupting said electrical connection.

3. The transponder according to claim 1, wherein said electrical connection is at least partially implemented by conductive ends (50).

4. The transponder according to claim 1, wherein said intermediate connecting element (4) comprises at least one fastening element (41) that guides positioning of detachable contact zones (10, 40).

5. The transponder according to claim 1, wherein said at least one portion of said detachable contacts (40) are located on said intermediate connecting element (4).

6. The transponder according to claim 1, wherein said detachable contacts consist of contact zones (10, 40) being able to come into contact two by two by pressing one of said two contact zones (10) against the second of said two contact zones (40).

7. The transponder according to claim 1, wherein said antenna consists of a coil (5) with ends (50) attached to said intermediate connecting element (4).

8. The transponder according to claim 3, wherein said ends (50) are free.

9. A transponder comprising:

an integrated circuit (1); and

an antenna (5) electrically connected in a detachable manner to said integrated circuit (1) via a detachable electrical connection,

wherein said detachable electrical connection comprises at least one intermediate connecting element (4),

the at least one intermediate connecting element is separate from the integrated circuit,

wherein said intermediate connecting element (4) guides positioning of at least one portion of said detachable contacts (40) by fastening elements (41),

wherein said intermediate connecting element consists of a printed circuit (4), said at least one portion of said detachable contacts consisting of contact zones (40) on the first surface of said printed circuit (4),

further comprising on the surface opposite said first surface of said printed circuit (4) permanent contact zones (42) allowing connection of the antenna (5) in a fixed manner, each of these permanent contact zones (42) being electrically connected to one of contact zones (40) via a path (43) through said printed circuit (4).
