RJ

RJ是Registered Jack的缩写,意思是“注册的插座”。在FCC(美国联邦通信委员会标准和规章)中RJ是描述公用电信网络的接口,计算机网络的RJ45是标准8位模块化接口的俗称。

CodeConnectorUsage
RJA1X225A adapterConnector for a modular plug to a four-prong jack
RJA2X267A adapterConnector for splitting one modular jack to two modular jacks
RJA3X224A adapterConnector for adapting a modular plug to a 12-prong jack
RJ2MB50-Pin2–12 telephone lines With make-busy arrangement
RJ11(C/W)6P2CEstablishes a bridged connection for one telephone line (6P4C if power on second pair)
RJ12(C/W)6P6CEstablishes a bridged connection for one telephone line with key telephone system control ahead of line circuit
RJ13(C/W)6P4CSIMilar to RJ12, but behind the line circuit
RJ14(C/W)6P4CFor two telephone lines (6P6C if power on third pair)
RJ15C3-pin weatherproofFor one telephone line for boats in marinas
RJ18(C/W)6P6CFor one telephone line with make-busy arrangement
RJ21X50-pinMultiple (up to 25) line bridged T/R configuration
RJ25(C/W)6P6CFor three telephone lines
RJ26X50-pinFor multiple data lines, universal
RJ27X50-pinFor multiple data lines, programmed
RJ31X8P8CAllows an alarm system to seize the telephone line to make an outgoing call during an alarm. Jack is placed closer to the network interface than all other equipment. Only 4 conductors are used.
RJ32X8P8CLike RJ31X, this wiring provides a series tip and ring connection through the connecting block, but is used when the customer premises equipment is connected in series with a Single station, such as an automatIC dialer.
RJ33X8P8CThis wiring provides a series tip and ring connection of a KTS line ahead of the line circuit because the registered equipment requires CO/PBX ringing and a bridged connection of the A and A1 lead from behind the line circuit. Tip and ring are the only leads opened when the CPE plug is inserted. Typical usage is for customer-provided automatic dialers and call restrictors.
RJ34X8P8CSimilar to RJ33X, but all leads are connected behind the line circuit.
RJ35X8P8CThis arrangement provides a series tip and ring connection to whatever line has been selected in a key telephone set plus a bridged A and A1 lead.
RJ38X8P4CSimilar to RJ31X, with a continuity circuit. If the plug is disconnected from the jack, shorting bars allow the phone circuit to continue to the site phones. Only 4 conductors are used.
RJ41S8P8C, keyedFor one data line, universal (fixed loop loss and programmed)
RJ45S8P8C, keyedFor one data line, with programming resistor
RJ48C8P4CFor four-wire data line (DSX-1)
RJ48S8P4C, keyedFor four-wire data line (DDS)
RJ48X8P4C with shorting barFor four-wire data line (DS1)
RJ49C8P8CFor ISDN BRI via NT1
RJ61X8P8CFor four telephone lines
RJ71C50-pin12 line series connection using 50-pin connector (with bridging adapter) ahead of customer equipment. Mostly used for call sequencer equipment.

防误插

      防误插有两方面:一方面是连接器本身,连接器本身旋转180度、错位错误连接导致信号错误连接,此时需要注意尽可能选择防误插连接器,或者通过调整连接器相对位置关系使装配唯一化;另一方面,出于减少物料种类考虑,几种信号都采用相同连接器,此时就可能出现将A插头插到B插座上去,此时就需要注意,如果出现这样情况时会引起严重后果(非简单告警,带有破坏性)的时候,必须将A、B接口选择为不同类型的插座(例如A为male,B为female);
