HJKT cable terminal block is used to joint 0.32-0.80mm diameter communication cables.It can directly connect, bridge and multiple connect cables, and is widelyapplied for communication circuits. No wire stripping is required for connection.Cables are connected through press joining by simple tools.Characteristics:HJKT1 button terminal block has single tab and is dampproof, applied to two-wireconnection.HJKT2 button terminal block has two tabs and is dampproof, applied to two-wire connection.HJKT3 button terminal block has two tabs and is dampproof, applied to three-wireconnection (mutable connection).HJKT4 button terminal block has single tab and is dampproof, applied to bridge andmutable connect trunk cables HJKT5 button terminal block has two tabs and is dampproof, applied to bridge andmultiple connect trunk cables.When using this terminal block, press it with your thumb onto the wire to pre-position.HJKT7 button terminal block has two tabs and is dampproof, applied to connectionof two-wire telephone cable core.The shell is molded from high quality engineering plastic. The tab is made from copperalloy. The joints are sealed with silicon grease, waterproof and corrosion-proof.Main technical indexes:1) Ambient temperature: -30癈~+70癈2) Relative humidity: d85%3) Ambient atmosphere pressure: 70-106KPa 4) Insulation resistance: e1x10m ?between every two terminals (undernormal temperature and humidity)5) Contact resistance: d5m?between connection card and wires6) Dielectric intensity: 2,000V DC voltage (or 1,400V AC) is imposed between themetallic wire that is connected to the module and insulation shell (sleeve), andno module damage or spark breakdown takes place within one minute producing area:China
