ABSTRACT:
An attachment and disengagement tool (30) is provided for a bayonet connector (1) for an optical fiber cable (2). The bayonet connector (1) comprises a coupling nut (14) moveable axially over the body of the connector (1). The nut (14) has a pattern of raised knurls (21) and further has J-shaped bayonet slots (22) for accepting of the bayonet pin (23) of a coupling bushing (24) complementary to the connector (1). The attachment and disengagement tool (30) comprises a trough-shaped main body (31) with cup-shaped center bore (32) extending therethrough, and a cradle-shaped forward extension (36) with cup-shaped bore (37) coextending with the bore (32) of the main body (31) and partially inset into the front of the main body (31) to form a partial annular shoulder (38) at the intersection of the extension (36) with the main body (31). The extension (36) has forward-extending L-shaped engaging tangs (39) with rear stems (40) forming latching recesses (41) circumferential to the common bore (32, 37). The latching recesses (41) are shaped to accept the pattern of raised knurls (21) of the coupling nut (14). The tool (30) is used in a method of disengaging a connector (1) from packed bushings (24) and in a method of attaching a connector (1) to such bushings (24).
