Communication telephone switching box installed outdoors, is communication cables for local telephone trunk and distribution cable junction to end devices in the box with a jumper to connect arbitrary manner to complete the transfer function between the trunk cable wiring and the wiring cables. Cable transfer box capacity from 100 pairs line up to 3200 pairs of lines, its structure has two kinds: single-sided and double-sided, floor installation and pole mounting bracket. Is divided into two kinds according to the wiring: Rotary card (106) and the snap of the formula (107). The product has excellent corrosion resistance. Door, floor sealing plate has a sealing device to prevent rain and moisture into the box. 2. Communication telephone switching box use environment: temperature -40 ~ + 55 ℃ Relative humidity ≤95% at 40 ℃, atmospheric pressure 70 ~ 106Kpa 3. Electrical performance communication telephone junction box: contact resistance ≤3mΩ Insulation resistance ≥5 × 104MΩ anti- Dielectric strength 50HZ, 500V AC voltage 1min without breakdown and arcing phenomena. 4. Communications Telephone installation and use of a transfer box, floor installation by the transfer of the bottom surface of the cement foundation sized bezel, bezel compressive strength greater than 750kg / cm 2 After the cement foundation box to be fully solidified, the transfer case into the cement foundation box seat with nuts, frame bar pre-installed by the site size requirements two vertical cement pole, cement pole installation site. Transfer box mounted on the station platform and fasteners securely connected, floor height from the ground is not less than 2600mm. 3, the pressure card module cable connecting operation a, with a screwdriver, press the steel back shelf clamping (3) Remove the module (leaving only the lowest end of a module) b seal is removed from the bottom of the tank, according to the diameter of the cable cut off Sealing and then loaded to its original position. c remove the cable through the sealing gasket into the transfer box. d, stripping the cable sheath, stripping length is equal to the top on a module, the distance between the beams plus 200mm, with a cable clamp cable wire truss beams next deputy e, cable wire from top to bottom in order for a group of 10 pairs, the core wire with nylon buckle fixed to the bottom left of the back frame of steel. 6,10 for threading wire through the bottom of the module folder, and then set into each side of the module on the line stringing cable slot on the rear springs snap groove, with a special tool pressed into the reed slot. 4, patching a, a pair of jumpers on the card were placed in the folder reed line trunking, with card access tool jumper pushed snap reed folder trunking. b, 1 至 5 by the left of the leads, 6-10 pairs on the right leads, and then were cited on the lug connector slot, and then push the card access tools reed slot. At the same time cut off the excess wire. c, removal, the line snap hook on the tool open, hooked up the cable lift, to dismantle 5, rotary card module cable connecting operation a, hands on the wiring module positioning buckle, along the vertical axis module, so that the module negative towards staff; b, the cable through the bottom of the box from the transfer ring hole transfer box; c, stripping the cable sheath, stripping length is equal to the top of the module on a fast distance between the beams to the plus 200mm, and clip the cable core cable truss next vice beam; d, according to the cable chromatography with 25 pairs of lines from bottom to top order for a group of core wire with nylon buckle fixed on the middle rack of steel back. e, put each set of wires according to the requirements of each pilot chromatography line penetration within five pairs corresponding threading module wiring board, f, according to the core principles and terminal colors correspond respectively to each wire line through the terminal holes screwdriver clockwise 900; g, with a meter to check and correct the wiring module to the starting rotation position, the module automatically after positioning firm cable connection is completed.
