Abstract

Termination shelf for telecommunications cable with mounting positions for conductor connector devices. The mounting positions are accessible from one side of the shelf for insertion of the connector devices. Also a guide is provided to enable a flexible transmission element to be inserted into the tray from the same side as for shelf insertion, the guide being shaped to guide the transmission element towards a remote side of the frame and then to guide the tramsmission element in the opposite direction through the mounting position. Frontal loading of the connector devices and of incoming conductors is thereby a use feature with the termination shelf.

Claims

1. A termination shelf for telecommunications cable, comprising a first side and a second side remote from the first side, mounting positions for mounting a plurality of conductor connector means in mounting positions in the shelf with access to said first side, and a plurality of guide means, one for each mounting position, each guide means having first and second in-series guide parts and in each of which:

the first guide part extends from the first side towards the second side of the shelf for guiding a flexible telecommunications cable transmission element positioned at the first side and fed into the first guide part along a fixed path through the shelf towards the second side; and

the second guide part is in-series with the first guide part to receive the transmission element from the first guide part, the second guide part being curved so as to guide the transmission element along a curved path and through a corresponding mounting position towards the first side of the shelf.

2. A termination shelf according to claim 1 mounted within a distribution frame having a front and a rear and with the first side of the shelf positioned at the front of the frame and with the first guide part extending towards the rear of the frame.

3. A termination shelf according to claim 1 mounted within a distribution frame having a front, a rear and two sides, the shelf being disposed so that the two sides of the shelf are spaced in a direction between the sides of the frame.

4. A termination shelf according to claim 1 wherein each mounting position is provided by a chamber within the shelf, the chamber having an access opening at said first side of the shelf, the first guide part comprising a first wall extending from said first side towards the second side of the shelf, and the second guide part comprising a second wall located towards the second side of the shelf, the first and second walls separating the chamber from a guide passage for the flexible cable transmission element except for an outlet from the guide passage at a end of the second wall into the chamber with the outlet facing forwardly towards the first side of the shelf.

5. A termination shelf for telecommunications cable and a plurality of conductor connector means, the shelf comprising a first side and a second side remote from the first side and mounting positions for mounting the plurality of conductor connector means in mounting positions in the shelf by sliding reception of the conductor connector means into the mounting positions through an access opening at said first side, the shelf also comprising a plurality of guide means, one for each mounting position, each guide means having first and second in-series guide parts and in each of which:

the first guide part extends from the first side towards the second side of the shelf for guiding a flexible telecommunications cable transmission element positioned at the first side and fed into the first guide part along a fixed path through the shelf towards the second side; and

the second guide part is in-series with the first guide part to receive the transmission element from the first guide part, the second guide part being curved so as to guide the transmission element along a curved path and through a corresponding mounting position towards the first side of the shelf.

6. A termination shelf and a plurality of conductor connector means according to claim 5 wherein each mounting position is provided by a chamber within the shelf, the chamber having an access opening at said first side of the shelf, the first guide part comprising a first wall extending from said first side towards the second side of the shelf and the second guide part comprising a second wall located towards the second side of the shelf, the first and second walls separating the chamber from a guide passage for the flexible cable transmission element except for an outlet from the guide passage at an end of the second wall into the chamber with the outlet facing forwardly towards the first side of the shelf.

7. A termination shelf and a plurality of conductor connector means according to claim 6 wherein another wall is provided for each chamber, said other wall spaced across the chamber from and opposed to the first wall for the sliding reception of a corresponding conductor connector means between the first and the other walls and into the chamber.
