The present invention provides a connector for terminating an optical fiber. The connector comprises a one-piece housing, a ferrule assembly and an insert. The insert has keys formed thereon that are adapted to mate with keyways formed in the housing. The housing has a first opening formed therein that first receives the ferrule assembly and then the insert and a second opening opposite the first opening. The end of the ferrule assembly that holds the end of the optical fiber protrudes through the second opening. The insert has a flange thereon that has two oppositely located flat surfaces and two oppositely located keys. The keys each have a chamfered surface. The keys and the flat surfaces of the flange provide the flange with a substantially rectangular cross-section. The first opening formed in the housing has a substantially square cross-section. When the insert is inserted into the first end of the housing, the substantially square cross-section of the opening aligns with the oppositely located flat surfaces of the flange to thereby cause the keys of the flange to align with the keyways formed in the surfaces of the housing. The chamfered surfaces of the keys deflect the sides of the housing outwardly as the insert is inserted into the housing. The keys of the insert are then received by the keyways formed in the housing to lock the insert into place within the housing.

Optical connector having a one-piece housing

A push nut fastener has first and second gripping openings. The first gripping opening is substantially circular and the second gripping opening is substantially rectangular. The substantially circular gripping opening has a plurality of blades or finger-like engagement portions extending from the outer circumference of the substantially circular gripping opening towards the center of the substantially circular gripping opening. The substantially rectangular gripping opening has a plurality of blades or finger-like engagement portions extending from the outer perimeter of the substantially rectangular gripping opening towards the center of the substantially rectangular gripping opening. The substantially rectangular gripping opening includes at least two blades or finger-like engagement portions, a respective blade extending from each of two opposing sides of the substantially rectangular gripping opening. The push nut may have flanges formed at two opposing ends of the member. The flanges may be formed integrally from the same piece of material as the push nut fastener. The flanges may have unequal lengths, to differentiate one end of the push nut fastener from the other end. The push nut fastener may be included in electrical components, for example in a DSX jack. An exemplary digital signal cross-connect jack has a respective pair of posts extending from each side, with a respective push nut fastened to each respective pair of posts.

Twin impression push nut

A jack assembly is provided in which the central body of the assembly includes integrally cast posts for aligning and securing follower springs, wiper springs and spacers. To assemble the jack, the follower springs, wiper springs and spacers are stacked onto the posts and then secured with a pushnut that engages the posts with a friction fit, avoiding separation from the central body.

Jacks formed by die casting

Disclosed is a patch cord connector and connector block combination which results in low insertion forces and enhanced side-to-side stability for the patch cord connectors. The patch cord connector includes a latch member formed in a portion of one surface of the connector housing, and the connector block includes a series of grooves formed in its housing for receiving the latch.

Connecting block and patch cord combination

A cable which may be used in buildings in concealed areas such as in plenums or in riser shafts includes a core (22) which includes at least one transmission medium each of which is enclosed with a non-halogenated plastic composition of matter. The core is enclosed with a jacket (28) which also is made of a non-halogenated plastic composition. The non-halogenated plastic material of the insulation includes a polyetherimide constituent and an additive system. The additive system includes an antioxidant/thermal stabilizer and a synergistic metal deactivator and may include a lubricant. For the jacket, the plastic material is a composition which may include a siloxane/polyimide copolymer constituent blended with a polyetherimide constituent and an additive system to improve processing and long term aging, or a siloxane/polyimide copolymer constituent with a flame retardant system.
