Abstract

An electronic device (1) has a can housing (3) and a method for producing the same. The can housing (3) has an open end face (4). A plug-in unit (5) can be inserted into the can housing (3) through the end face (4). The plug-in unit (5) has a populated circuit board (6) and a multicontact connector (7). The can housing (3) has an integrated connector collar (8), which integrally extends the can housing (3) and surrounds the multicontact connector (7) and contact elements (9). The connector collar (8) forms a fit for a mating connector. The insert has the circuit board (6) and a contact carrier (10) having the multicontact connector (7) without the connector collar (8). The outer contour (11) of the contact carrier (10) is at least partially matched to the inner contour (12) of the connector collar (8).

Claims

1. An electronic device having a can housing having:

a can housing with an open end face via which a plug-in unit can be inserted into the can housing, wherein the plug-in unit has a populated printed circuit board and a multicontact connector,

wherein the can housing has an integrated connector collar which integrally extends the can housing and surrounds the multicontact connector with contact elements and forms a fit for a mating connector, and wherein the plug-in unit has the printed circuit board and'"'"'a contact carrier with the multicontact connector without the connector collar, wherein the outer contour of the contact carrier is at least partially matched to the inner contour of the connector collar.

2. The electronic device according to claim 1, wherein the interior of the can housing has guide ramps for insertion of the printed circuit board into an end position.

3. The electronic device according to claim 1, wherein the connector collar has an opening with dimensions which correspond to the width of the plug-in unit composed of the printed circuit board with the contact carrier.

4. The electronic device according to claim 1, wherein

the can housing has an interior which has clamping regions and locking regions for the printed circuit board.

5. The electronic device according to claim 1, wherein

the can housing has, in the interior, lateral guide grooves which are in engagement with edge regions of the printed circuit board.

6. The electronic device according to claim 1, wherein the electronic device is a device of a vehicle.

18. The electronic device according to claim 6, wherein the electronic device has a device of the group consisting of electronic parking brake, electronic guidance device, engine control device, transmission control device, antilock braking device and electronic safety control device.

7. A method for producing an electronic device having a can housing, comprising:

manufacturing a can housing with an connector collar which corresponds in its integral dimensions to the interior of the can housing;

producing a printed circuit board with populating elements, the width of which printed circuit board corresponds to a clear width of the can housing;

producing a contact carrier with contact elements of a multicontact connector, wherein the outer contour of the contact carrier is at least partially matched to the inner contour of the connector collar;

connecting the contact carrier to the printed circuit board to form a compact plug-in unit; and

inserting the compact plug-in unit into the can housing accompanied by positioning of the contact carrier with the multicontact connector in the connector collar of the can housing.

8. The method according to claim 7, wherein the can housing is produced with an integral connector collar by means of injection molding technology.

9. The method according to claim 7, wherein

the contact elements are embedded in the contact carrier by means of an injection molding method.

10. The method according to claim 7, wherein

in order to produce the contact carrier, contact elements are produced which are inserted into a prefabricated injection molded part with the outer contour of the contact carrier in prefabricated slit-shaped guide openings in the injection molded part and are connected in a frictionally locking or materially joined fashion to the injection molded part to form a contact carrier.

11. An electronic device having a housing comprising

an open end face via which a plug-in unit having a multicontact connector can be inserted into the housing, and

an integrated connector collar which integrally extends the housing and surrounds the multicontact connector with contact elements and forms a fit for a mating connector, and wherein the plug-in unit comprises a printed circuit board and a contact carrier with the multicontact connector without the connector collar, wherein the outer contour of the contact carrier is at least partially matched to the inner contour of the connector collar.

12. The electronic device according-to claim 11, wherein the interior of the housing has guide ramps for insertion of the printed circuit board into an end position.

13. The electronic device according to claim 11, wherein the connector collar has an opening with dimensions which correspond to the width of the plug-in unit composed of the printed circuit board with the contact carrier.

14. The electronic device according to claim 11, wherein the housing has an interior which has clamping regions and locking regions for the printed circuit board.

15. The electronic device according to claim 11, wherein the housing has, in the interior, lateral guide grooves which are in engagement with edge regions of the printed circuit board.

16. The electronic device according to claim 11, wherein the electronic device is a device of a vehicle.
