Connection box with strain relief

Abstract

Fiber optic connection box with a housing and a strain relief device for fixing a first sheath of at least one or for at least a first fiber optic cable, wherein the strain relief device has a clamping element that is or can be detachably mounted in the housing, and a receptacle for the first sheath that is accessible after the clamping element has been released and removed, wherein the strain relief device is designed such that the clamping element contributes to clamping the first sheath relative to the housing after the first sheath has been inserted into the receptacle and after the clamping element has been reassembled in the housing, wherein the clamping element has a holding structure for at least one second fiber optic cable on a side of the clamping element facing away from the first sheath in its clamped state.

Claims

[1] Fiber optic connection box with a housing and a strain relief device for fixing a first sheath of at least one or for at least a first fiber optic cable, wherein the strain relief device has a clamping element which is detachably mounted or mountable in the housing, and a holder for the first sheath, which is accessible after loosening and dismantling the clamping element, wherein the strain relief device is designed such that the clamping element contributes to clamping the first sheath relative to the housing after insertion of the first sheath into the receptacle and after reassembly of the clamping element in the housing, wherein the clamping element has a holding structure for at least one second fiber optic cable on a side of the clamping element facing away from the first sheath in its clamped state. [2] Connection box according to claim 1, wherein the holding structure is designed for a second sheathing of at least the or for at least the second fiber optic cable. [3] Connection box according to claim 2, wherein the clamping element has at least one recess, preferably opening, for fixing a cable tie relative to the clamping element, with which cable tie the at least one first or second sheath can be clamped to the clamping element and thus fixed to the housing. [4] Junction box according to claim 3 with at least one recess for fixing a cable tie on one side of the clamping element and at least one further recess for fixing a further cable tie on another side of the clamping element, wherein the recess for the cable tie is provided with a recess sufficiently wide to accommodate a closure of the cable tie on that side which is opposite to the receptacle for the sheath which is accessible after dismantling the clamping element. [5] Connection box according to one of the preceding claims, in which the clamping element can be dismantled transversely to a line direction of the first sheath. [6] Connection socket according to one of the preceding claims, in which the first sheath can be inserted into the receptacle in the inserted position transversely to its line direction when the clamping element is dismantled. [7] Connection box according to one of the preceding claims, in which the strain relief device has a guide for the clamping element, in or along which the clamping element can be brought into and released from the mounted position, and preferably has a locking device for lockingly mounting the clamping element. [8] Connection box according to one of the preceding claims, in which the clamping element has claw projections on at least one of its sides to improve the fixing of the at least one first or second sheath. [9] Connection box with a housing seal for sealed passage of the at least one first or second sheath through a housing wall, which housing seal is preferably arranged outside the strain relief device. [10] Connection box according to one of the preceding claims with a plurality of strain relief devices of the type described next to one another. [11] Connection box according to claim 10, wherein the plurality of strain relief devices are arranged next to one another parallel to a housing wall and are associated with a plurality of seals in the housing wall for passing through fiber optic cables, in particular sheaths, wherein the seals are preferably adaptable to different cable dimensions by separating elastomer body parts. [12] Connection box according to claim 10 or 11, in which the plurality of strain relief devices are arranged next to one another parallel to a housing wall and are assigned to a plurality of seals in the housing wall for passing through fiber optic cables, in particular sheaths, which seals are designed for inserting a respective fiber optic cable transversely to the cable direction. [13] Use of a junction box according to one of the preceding claims for fixing at least one first or second casing relative to the housing. [14] Use according to claim 13, wherein the at least one sheath is an empty pipe and the connection box is used for blowing at least one fiber optic cable, preferably a strand cable, through the empty pipe and connecting the fiber optic cable or at least some of the fiber optic cables of the strand cable in the connection box. [15] Use according to any one of claims 13-14, in which use a plurality of junction boxes according to any one of claims 1-12 are used and for at least two of the plurality of sheaths with different diameters are fixed in the respective junction box.
