characterised in that
the terminal box ( 4 ) is inserted with its insertion end ( 8 ) in the insertion opening ( 5 ) and that its opposite connection end ( 9 ) protrudes from a holder ( 10 ) of the holding and connecting device ( 1 ).
3 . Holding and connecting device according to claim 1 ,
characterised in that
the holder ( 10 ) has an essentially smooth cover ( 11 ) in which the at least one insertion opening ( 5 ) is arranged, whereby components of the electrical circuit ( 2 ) are held and/or contacted on an interior side ( 12 ) of the cover ( 11 ).
4 . Holding and connecting device according to claim 1 ,
characterised in that
the edge flange ( 7 ) grabs behind the opening edge ( 6 ).
5 . Holding and connecting device according to claim 1 ,
characterised in that
the edge flange ( 7 ) is formed essentially as a U-shaped groove ( 13 ) in whose U-shaped opening ( 14 ) the opening edge ( 6 ) engages.
6 . Holding and connecting device according to claim 1 ,
characterised in that
the opening edge ( 6 ) is formed as an edge leg ( 15 ) that essentially sticks out perpendicularly from the interior side ( 12 ).
7 . Holding and connecting device according to claim 1 ,
characterised in that
the edge leg ( 15 ) makes a sealing contact with the groove bottom ( 16 ) of the groove ( 13 ).
8 . Holding and connecting device according to claim 1 ,
characterised in that
the length ( 17 ) of the edge leg ( 15 ) is smaller than the depth ( 18 ) of the groove ( 13 ) and the interior side ( 12 ) of the cover ( 11 ) lies on the free end ( 19 ) of the outer U-shaped leg ( 20 ) of the groove ( 13 ) such that a seal is formed.
9 . Holding and connecting device according to claim 1 ,
characterised in that
a counter leg ( 21 ) opposite the edge leg ( 15 ) sticks out from the exterior side ( 12 ) of the cover ( 11 ).
10 . Holding and connecting device according to claim 1 ,
characterised in that
the edge leg ( 15 ) and/or the counter leg ( 21 ) extend parallel to a wall ( 23 ) of the terminal box ( 4 ).
11 . Holding and connecting device according to claim 1 ,
characterised in that
the edge leg and/or counter leg ( 15 , 21 ) run at a distance frm the wall ( 23 ) of the terminal box ( 4 ).
12 . Holding and connecting device according to claim 1 ,
characterised in that
the seal between the terminal box ( 4 ) and holder ( 10 ) is free of sealing material.
13 . Holding and connecting device according to claim 1 ,
characterised in that
a bottom wall ( 24 ) of the terminal box ( 4 ) has a multiple number of openings ( 25 ) for feeding through electrical lines or the like.
14 . Holding and connecting device according to claim 1 ,
characterised in that
the bottom wall ( 24 ) has a number of spacing elements ( 27 ) on its bottom side ( 26 ), which is facing the electrical circuit ( 2 ).
