  • Patent number: 6259033
    Abstract: A holding device for sealed insertion of cables (18) through enclosure walls, having a holding plate with several cable lead-through openings (13), which can be mounted on the enclosure wall also having cable lead-through openings, and an elastic sealing plate (11), which in the mounted state is located between the holding plate (10) and the enclosure wall. The sealing plate (11) has pre-manufactured cable perforation points (14) in true alignment with the cable lead-through openings (13). Furthermore, the holding plate has flexible holding tabs (15) extending sideways into the cable lead-through openings (13), and each of the tabs is deflected toward the enclosure wall if a cable (18) is inserted into the appropriate cable opening (13) and, if tensile strain is placed upon the cable (18), digs into the cable in the opposite direction, whereby the deflection toward the wall remains.

  • Patent number: 6216320
    Abstract: A cable holding arrangement with a holding plate (10) is suggested which has a plurality of similar holding openings (11) arranged next to each other in a row. At least one holding clip (13) has two plug feet (15) connected with one another through a holding area (14) for insertion into two of the holding openings (11). In the inserted condition, the holding clip (13) forms a U-shaped arrangement through which a cable (12) to be secured can be engaged and pressed against the holding plate (10). The plug feet (15) have a stop arrangement (16) locating with the holding openings (11). In this way, cables (12) can be secured in different ways to the holding plate (10) by simple insertion of a holding clip, simple release and shifting also being possible.

  • Patent number: 5831216
    Abstract: A profile strip of insulating material is proposed for holding many electrical cables (27)-(30) in switching and control boards and panels, which consists of a mounting section (13) for fastening on a mounting track and a comb-like cable holding section (15) formed thereon. This cable holding section (15) consists of many parallel teeth (14), between which insertion slits (26) for insertion or installation of electrical cables are formed. The insertion slits (26) are limited at the sides by elastic tabs (21) formed on the teeth (14). Between every two teeth (14) a shorter intermediate tooth (20) is positioned such that it divides a portion of the insertion slit (26) into two narrower partial slits. This permits the elastic tabs (21) to hold, in variable fashion, not only cables of smaller diameter (29) in the portion with the intermediate tooth, but also cables of larger diameter (27), (28) in the remaining portion.
