10. The locking assembly as claimed in claim 7, wherein an inner diameter of the third part of the through hole is smaller than that of the second part, but larger than or equal to the outer diameter of the threaded portion.
11. The locking assembly as claimed in claim 7, further comprising a resilient member disposed in the through hole of the sleeve above the stepped portion.
12. The locking assembly as claimed in claim 11, wherein an outer diameter of the resilient member is larger than the inner diameter of the third part of the through hole, but smaller than the inner diameter of the second part of the through hole.
13. The locking assembly as claimed in claim 1, wherein an inner diameter of the resilient member is larger than the outer diameter of the threaded portion, but smaller than the diameter of the head portion of the fastener.
14. The locking assembly as claimed in claim 7, wherein the sleeve further comprises a flange portion extending out from an outer surface thereof adjacent a distal end of the first part of the through hole.
15. The locking assembly as claimed in claim 1, wherein the depth of the through hole of the sleeve is larger than or equal to the length of the locking member.
16. The locking assembly as claimed in claim 1, wherein the restricting member is positioned in an inner surface of the through hole of the sleeve, the restricting member comprising an elastic latch extending into the through hole and inclined toward one end of through hole.
17. The locking assembly as claimed in claim 1, wherein the restricting member is a locking washer, the lock washer is an elastic ring body, an inner diameter of the elastic ring body is smaller than the diameter of the locking portion of the locking member, and an outer diameter of the elastic ring body is larger than the inner diameter of the through hole, the lock washer is pressed into the through hole.
18. A locking assembly, comprising:
a locking member including a locking portion; and
a sleeve defining a through hole therein for holding and guiding the locking member, the through hole including a first part and a second part;
a restricting member positioned in the through hole of the sleeve, wherein after the locking portion of the locking member passes through the restricting member, the restricting member blocks the locking portion from sliding out of the sleeve.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A ferrule for containing and aligning a plurality of optical transports, the optical transports having a longitudinal dimension comprising:
a ferrule body having a front face, a rear face, and at least one lateral side face extending between the front face and the rear face;
a longitudinal cavity running from the front face to the rear face for receiving a plurality of optical transports, the longitudinal cavity having a lateral side opening through the at least one lateral face; and
a multiplicity of rows of optical transports, each row comprising a multiplicity of optical transports.
2. The ferrule of claim 1 further comprising a cover positioned in the longitudinal cavity so as to close off the lateral side opening of the cavity.
3. The ferrule of claim 1 wherein the longitudinal cavity has a surface substantially opposite the lateral side opening, the surface having a plurality of longitudinal grooves, and wherein at least some of the optical transports are disposed in the longitudinal grooves.
4. The ferrule of claim 3, wherein the optical transports in a first one of the rows are disposed in the grooves.
5. The ferrule of claim 4 further comprising:
a lateral alignment feature on the front face of the ferrule for mating with mating lateral alignment feature of another ferrule for purposes of laterally aligning the ferrule with the another ferrule, wherein the grooves are precisely laterally aligned relative to the alignment feature.
6. The ferrule of claim 3 wherein the grooves are V-shaped.
7. The ferrule of claim 1 further comprising adhesive affixing the optical transports to the ferrule body.
