Connection box for fiber optics with seal

Abstract

Fiber optic connection box with a housing with housing walls and a seal in one of the housing walls for passing fiber optic cables through the housing wall, which seal is a one-piece elastomer body and has a plurality of sealing elements for at least one cable each and a web, which web connects the sealing elements to one another, wherein the housing wall has receptacles which are adapted to the sealing elements for introducing the sealing elements into the housing wall and into which the cables inserted into the sealing elements are or can be introduced in a direction transverse to a local line direction of the cables to be led through.

Claims

[1] Fiber optic connection box with a housing with housing walls and a seal in one of the housing walls for passing fiber optic cables through the housing wall, which seal is a one-piece elastomer body and a plurality of sealing elements for at least one line and a web, which web connects the sealing elements, the housing wall has receptacles, which are adapted to the sealing elements for the insertion of the sealing elements into the housing wall and into which the cables inserted into the sealing elements are or can be inserted in a direction transverse to a local cable direction of the cables to be passed through. [2] Connection box according to claim 1, in which the web also serves for sealing in addition to the sealing elements in the inserted state of the sealing elements and in the closed state of the housing. [3] Junction box according to claim 1 or 2, wherein the web has markings for separation. [4] Connection box according to one of the preceding claims, in which the receptacles and the sealing elements are designed such that the sealing elements are or can be introduced in a direction transverse to the local line direction. [5] Connection box according to one of the preceding claims, in which the sealing elements, seen in the local line direction and apart from the web, have a U-shaped contour with a straight piece between the leg ends of the U-shape, wherein the web is preferably provided on the straight piece and the U-shape is preferably tapered. [6] Connection box according to one of the preceding claims, in which the web has a T-profile shape when viewed in a longitudinal direction of the web. [7] Connection box according to one of the preceding claims with a housing cover pivotable about an axis, wherein the receptacles are provided in a housing wall opposite to the axis. [8] Connection box according to one of the preceding claims, in which the elastomer body, preferably at least one of the sealing elements, has a combination of at least two different types of leadthrough for cables. [9] Connection box according to one of the preceding claims, in which the elastomer body has at least one type of bushing, preferably two types of bushing, which can be adapted to different cable dimensions by separating parts from the elastomer body. [10] Connection box according to claim 9, in which one type of bushing has a grommet which varies in its inner diameter, preferably a stepped grommet, which can be adapted to different line dimensions by cutting off a part thereof, the stepped sections of the grommet preferably being non-concentric. [11] A junction box according to claim 9 or 10, wherein one bushing type comprises a detachable ring. [12] Junction box according to claim 10 or 11, in which the bushing type of claim 10 or 11 is provided twice. [13] Connection box according to one of the preceding claims with a feedthrough type for optionally one to a plurality of individual cables next to each other in the same feedthrough. [14] Connection box according to one of the preceding claims, in which at least one type of bushing has a marking for slitting the elastomer body into the bushing and for inserting a line transversely to the local line direction. [15] Connection box according to one of the preceding claims, in which at least some of the recesses of the bushing types are closed in the unused state by a membrane which can be sealed around a cable after it has been inserted.
