ABSTRACT:
The invention refers to an apparatus for inserting a flat cable into a housing, which ensures safeguarding the cable or the cable connections on the inside of the housing against tensile stress. The apparatus is to a large extent adapted to the measurements of the flat cable (width/thickness) and also offers sufficient protection in preventing foreign material from entering into the inside of the housing.
For this purpose, the housing is provided with a frame-shaped mounting part (1, 102) which has posts (14, 106) arranged on opposite sides. In the bottom area of the mounting part there is provided a cable passage (23, 104) facing towards the inside space of the housing, and in the mounting part there is provided a groove (22, 103) with rim-side shoulders (10, 105) for an insertable, elastic seal (2, 110). The seal is provided with a passage opening (28, 122) corresponding to the shape of the cross-section of the flat cable (9, 109). By interfacing the flat cable, tensile stress relief clamps (4,5; 116,117) can be bolted together with the posts (14, 106) of the mounting part.
The mounting part can be embodied as a separate component which can be screwed in front of a wall opening or a housing opening, or it can also be embodied in one piece together with the housing, for instance, a connector housing.
