A housing part having a service access configured to provide access for actuation of at least one screw arranged in an interior of a housing assigned to the housing part with a fixed relative position with respect to the service access, comprising:
- an opening defined in the housing part;
- a shoulder of the housing part that is inwardly directed and encloses the opening and which has an inner lateral surface;
- an insert having an outer lateral surface correlating with the inner lateral surface and which is inserted into and connected to the shoulder;
- a seal configured to seal off the inner lateral surface and the outer lateral surface being sealed off with respect to one another;
- at least one receiving slot arranged in the insert and configured for the actuation of the at least one screw, the at least one receiving slot is open at an inner end;
- and
- a detachable sealing plug configured to close an outer end of the at least one receiving slot,
- wherein the shoulder has at least two end surfaces which lie orthogonally with respect to the inner lateral surface and in one plane and to which the insert it is fastened in an abutting manner, and
- wherein an inner end of the at least one receiving slot is spaced apart from and faces the at least one screw so that only a portion of a screw head of the at least one screw projects into the at least one receiving slot.
A housing part having a service access configured to provide access for actuation of at least one screw arranged in an interior of a housing assigned to the housing part with a fixed relative position with respect to the service access, comprising:
- an opening defined in the housing part;
- a shoulder of the housing part that is inwardly directed and encloses the opening and which has an inner lateral surface;
- an insert having an outer lateral surface correlating with the inner lateral surface and which is inserted into and connected to the shoulder;
- a seal configured to seal off the inner lateral surface and the outer lateral surface being sealed off with respect to one another;
