BNC
The BNC connector, used in 10BASE2 environments, is an intrusive connector
much like the N-Type connector used with thick coaxial cable (described above).
The BNC connector (shown in Figure 4-12) requires that the coaxial cable be
broken at an annular ring to make the connection. Two BNC connectors are either
screwed onto or crimped to the resulting bare ends. Cabletron Systems
recommends the use of the crimp-on BNC connectors for more stable and
consistent connections. BNC connectors use the same pin-and-channel system to
provide a contact that is used in the thick coaxial N-Type connector.
BNC Male connectors are attached to BNC female terminators or T-connectors
(Figure 4-13). The outside metal housing of the BNC male connector has two
guide channels that slip over corresponding locking key posts on the female BNC
connector. When the outer housing is placed over the T-connector or terminator
locking keys and turned, the connectors will snap securely into place.
