A gel sealing device includes a gel sealing block (5) which provides a sealing section (22) through which the elongate parts (13, 14) extend. The gel sealing block (5) includes an upper flange (11) and a lower flange (12) with a support section (11a, 12a, 12b) disposed therebetween. The upper and lower flanges (11, 12) sandwiches, in direction of extension of the elongate parts (13, 14), a gel inner ring (7) supported by said support section (2) and a gel outer ring (6, 10a) covering the gel inner ring (7) in a radial direction extending transverse to said extension direction. The gel inner ring (7) and the gel outer ring (6, 10a) are made of a gel sealing material.

The present invention relates to a gel sealing device for sealing a passage of elongate parts through an opening. Such gel sealing device is preferably arranged in a housing used in telecommunication technology. The inventive gel sealing device comprises a gel sealing block (5) which provides a sealing section (22) through which the elongate parts (13) extend, wherein the gel sealing block (5) comprises an upper flange (11) and a lower flange (12) with a support section (11a, 12a, 12b) disposed therebetween. The upper and lower flanges (11, 12) sandwiches in direction of extension of the elongate parts (13), a gel inner ring (7) supported by said support section (2) and a gel outer ring (6, 10a) covering the gel inner ring (7) in a radial direction extending transverse to said extension direction. The gel inner ring (7) and the gel outer ring (6, 10a) are made of a gel sealing material, wherein the sealing section (22) is formed therebetween. The gel sealing block (5) is adapted to seal in the sealing section (22) a tube end of at least one tube (14) guiding at least one of the elongate parts.

Certain types of aggregation enclosures include cable input ports and downwardly angled cable output ports. A cover is pivotally coupled to the body so that the cover moves between an open position and a closed position. A modular component panel may be disposed within the enclosure. The component panel includes one or more distribution components (e.g., fiber distribution components or power distribution components) configured to connect at least a portion of an incoming cable to at least a portion of an outgoing cable.

A structured cabling system includes a plurality of data cables (6A-6F), one end of each cable being secured to a jack of a multiple jack assembly (1) and the other end of each cable being secured to an individual jack (9A-9F) located within a protective enclosure (11). The individual cables are mechanically secured to at least the protective enclosure (11) and/or a strain relief member (8) within the cable bundle is secured to the protective enclosure (11). The entire assembly may be pre-formed under factory conditions and delivered to an installation site. The multiple jack assembly (1) may then be secured, preferably by snap-fitting, to a rack assembly and the protective enclosure (10) may be used to draw the entire cable length to the required position. Once the cable is in position the protective enclosure (10) is discarded and the jack secured to their final use positions. In an alternative embodiment the protective enclosure forms a housing for jacks (9A-9F) in their final use position and may, for example, be snap-fitted to a floor box for this purpose.
摘要:
A port entry device (100) is described for inserting a telecommunication cable (60) containing optical fibers into a telecommunications enclosure (300). In particular, the port entry device (100) is an oval port sealing device. The port entry device includes a tubular housing (110), a split sleeve (130) and a pair of clamping nuts (120). The tubular housing has an interior passageway (113) between a first end (110a) of the housing and a second end (110b) of the housing. The interior passageway can include a first cable channel (111) and a second cable channel (112). The housing can have an elliptical cross section. The split sleeve (130) positions the telecommunication cable (60) within the port entry device (100) when the split sleeve (130) is inserted into the interior passageway (113) of the housing (110). The clamping nuts are attachable to the second end (110b) of the housing to secure the split sleeve (130) within the housing (110).
摘要:
A wire holder is provided which allows for reduced number of process steps required in bundling wires. The wire holder is for relative alignment of a plurality of wires upon bundling the wires, and includes a plurality of wall portions formed rotationally symmetric to one another, provided to project in a direction orthogonal to an axis O serving as a rotation symmetry axis, and extending along the axis O. Between opposite ones of the wall portions, recesses each having an arc shape in cross section are formed to hold the wires. Each of the recesses has a span length of not less than 85% of the diameter of each of the wires. By fitting the wires into the recesses and arranging them along the rotation symmetry axis, the wires can be aligned.
