6) The labels are clear and complete.
Insulation resistance: under normal ambient conditions, after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance between any two independent contacts, and/or between contacts and metal parts ≥ 1000MΩ
Contact resistance between contacts: under normal ambient conditions, the contact resistance between contacts ≤7 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤3 mΩ And after inserting the connection cord (or test cord) into the module for 200 times, the increasing resistance ≤3 mΩ
Contact resistance between conductor and contact: under normal ambient conditions, the contact resistance between contacts ≤3 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤2 mΩ. And after terminating for 200 times, the increasing resistance ≤2 mΩ.
Dielectric strength: under normal ambient conditions, after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance between any two independent contacts, and/or between contacts and metal parts is able to withstand an AC voltage of of 1000V (virtual value) at 45Hz~60Hz sinowave for 1 minute, without spark over and flying arc
Gas tight performance: contact touches the conductor at both sides, and thus forming the gas tight area, while the area of gas tight occupies ≥50% of the touched area on each side.
Conductor diameter range: 0.32mm-0.6mm, while insulation ≤ 1.4mm
Pulling strength:≥25N while pulling from the vertical side of the contacts
Flame retardant performance: all plastic parts are flame retardant, reaching grade of UL FV0
Life circle: ≥200 times
Outdoor DP Box Plastic for STB Modules 20pairs
Empty distribution box for 1pair dropwire module(STB module),offerring good connection environment for telecommunication.
Material:PC,with steel rails.
The subscriber connector unit consists of a rectangular box base with a cover and a connection module secured to the base.The top and base are hinged together, and the top is easily removable to facilitate working in cramped conditions.The cable grommets for wire entry and exit may be adjusted to conductor size and are also removable.A metal screw is provided for grounding purposes.
Application for replacing Tyco VX-SB subscribe connector unit terminal blocks,Connecting 1 pair module without protection,module with surge protection (gas-discharge instrument with surge protection to 230V) and module with overvoltage and overcurrent (overvoltage to 230V, and by two resistors PTC, which protect from the overcurrent).
