Slide arrangement for cable drawer
A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.
1. A telecommunications arrangement, comprising:
a) a module for mounting to a fixture, the module including a base for receiving fiber optic connections, the base of the module being selectively positionable in an open position and a closed position with respect to the fixture; and
b) a slide assembly interconnecting the module to the fixture, the slide assembly being configured to provide sliding movement of the base relative to the fixture, the slide assembly including:
i) a first rail member on the base;
ii) a second rail member fixedly secured to the fixture;
iii) a center rail member interconnected to each of the first and second rail members; and
iv) a spool positioned at the center rail member and configured to contact each of the first and second members to permit full-speed travel of the first rail member relative to the second rail member, and half-speed travel of the center rail member relative to the first rail member.
2. The telecommunications arrangement of claim 1 , further comprising a cable management device secured to the center rail member for movement with the center rail member, the cable management device configured to retain cables.
3. The telecommunications arrangement of claim 2 , wherein the cable management device includes a curved radius limiter.
4. The telecommunications arrangement of claim 1 , wherein the center rail member includes first and second longitudinal constructions, each of the first and second longitudinal constructions extending from a first end to a second end of the center rail member, the first rail member having a first structure configured to slidably engage the first construction of the center rail member, and the second rail member having a second structure configured to slidably engage the second construction of the center rail member.
5. The telecommunications arrangement of claim 4 , wherein the first longitudinal construction of the center rail member includes a first longitudinal groove extending from the first end of the center rail member to the second end, and the second longitudinal construction includes a second longitudinal groove extending from the first end of the center rail member to the second end.
6. The telecommunications arrangement of claim 5 , wherein the first structure of the first rail member includes a first interlocking structure, and the second structure of the second rail member includes a second interlocking structure, each of the first and second interlocking structures being configured to slidably engage the respective first and second grooves of the center rail member.
7. The telecommunications arrangement of claim 5 , wherein the center rail member has an I-shaped cross-section.
8. The telecommunications arrangement of claim 1 , wherein the spool is positioned within a receiving structure formed in the center rail member.
9. The telecommunications arrangement of claim 8 , wherein the spool has a snap-fit construction configured for receipt within the receiving structure of the center rail member.
10. The telecommunications arrangement of claim 1 , further including a catch arrangement configured to pause sliding movement of the first rail member when the first and center rail members have reached a first extended position.
11. The telecommunications arrangement of claim 1 , further including a positive stop arrangement configured to prevent linear separation of the first and second rail members from the center rail member.
