Motor vehicle lock
A motor vehicle lock has a locking mechanism with a rotary latch and at least one pawl, an electric drive and a gear mechanism arranged downstream of the electric drive, a lock housing with at least one housing cover, a cover cap and a housing shell, wherein at least one dry space can be formed in the lock housing by means of the housing cover and the cover cap, and a printed circuit board arranged in the dry space, wherein at least one electrical contact from the printed circuit board to the electric drive can be provided, and wherein the electrical contact between the printed circuit board and the electric drive can be arranged in the housing cover.
1 . A motor vehicle lock comprising:
a locking mechanism with a rotary latch and at least one pawl,
an electric drive comprising an electric motor and a gear mechanism arranged downstream of the electric motor,
a lock housing comprising at least one housing cover, a cover cap, and a housing shell, wherein the housing shell includes a seal that defines a first dry space and a second dry space, and
a printed circuit board arranged in the second dry space and the electric drive is arranged in the first dry space, wherein at least one electrical contact from the printed circuit board is connected to the electric drive, and wherein the electrical contact between the printed circuit board and the electric drive is arranged in the housing cover,
wherein the housing cover has a separating joint, wherein the separating joint forms at least part of a dry space boundary between the first and second dry spaces by engaging the seal.
2 . The motor vehicle lock according to claim 1 , wherein the electrical contact extends through the separating joint.
3 . The motor vehicle lock according to claim 1 , wherein the electrical contact is injection molded in the housing cover.
4 . The motor vehicle lock accordingly to claim 1 , wherein the separating jointed is arranged in a cavity in the lock housing, the cavity being a filling region for receiving a sealing compound.
5 . The motor vehicle lock according claim 1 , wherein the electrical contact is held in the housing cover in a form-fitting manner.
6 . The motor vehicle lock accordingly to claim 5 , further comprising locking elements that secure the electrical contact to the housing cover in the form-fitting manner.
7 . The motor vehicle lock according to claim 1 , wherein the electrical contact extends through an opening in the housing cover in a region of the separating joint.
8 . The motor vehicle lock according to claim 7 , wherein the opening extends at least in some regions in a direction of an outer surface of the lock housing.
9 . The motor vehicle lock according to claim 7 , wherein the opening is filled by a sealing compound.
10 . The motor vehicle lock accordingly to claim 7 , wherein the opening is accessible from an outer surface of the motor vehicle lock and the housing cover when the motor vehicle lock is in a closed state.
11 . The motor vehicle lock according to claim 1 , further comprising a resilient second seal arranged in the housing cover, and the electrical contact extends through the second seal.
12 . The motor vehicle lock according to claim 11 , wherein the second seal is arranged in the dry space of the printed circuit board.
13 . The motor vehicle lock according to claim 1 , wherein the electrical contact is configured as a conductor track.
14 . The motor vehicle lock according to claim 13 , wherein the conductor track is connected to the printed circuit board by an insulation displacement connection.
15 . The motor vehicle lock accordingly to claim 13 , wherein the conductor track is configured as a conductor track structure comprising multiple individual electrical contact tracks.
16 . The motor vehicle lock accordingly to claim 13 , wherein the conductor track includes spring-loaded electrical contacts.
