CHL-4 mine safety cable connector mine safety circuit cable connector is based on Q004-2007 standard production. Is a dedicated connection device intrinsically safe mine systematic communication cable, the connector has a small size, light weight, easy to connect, secure and reliable, mainly used in coal mines vibration, shock, water spray and dust and gas have other occasions explosive gas mixtures. The connector has two and four channels can be used for connecting a pair or two of intrinsically safe communications cables, three five-on-five, etc. can be accessed. Explosion-proof type: Mine intrinsically safe. Explosion-proof mark: Exib Ⅰ. Third, the technical parameters 1, the main technical indicators: Ambient temperature -10 ℃ - +40 ℃; Relative humidity: ≤ 95% (+25 ℃ when) 2, the main parameters of the rated voltage 60V, rated current 3A; contact resistance is not greater than 0.01Ω (normal), insulation resistance of not less than 100MΩ, can be connected to the cable diameter 6mm ≤ D ≤ 12mm. Can be connected to the wire diameter D ≤ 3mm. Fourth, the structural characteristics: 1, shell and repression by the phenolic plastic cloth, components made of metal, and the rest gaskets, seals plastic parts, rubber parts. 2, Dimension D50mm × 144mm; Weight 150g. Fifth, install and use one, unscrew the middle of connected sets aside patch pressure line devices. 2 Unscrew the cable gland nut, remove the seals and gaskets. 3, depending on the connection cable diameter, choose the appropriate specifications sealing gasket, also the import and export of the inner diameter of the connector, there are 6mm, 8mm, 10mm, 12mm four kinds (in the order should pay attention to the outer diameter of the cable connection) and OK. 4, connect the cable wire string compression nut, gaskets and seals, were inserted into the cradle. 5, stripped cable wire head, insert the terminal, and then Tighten the screws. 6, will wear a patch device intermediate ring gaskets, according to the same positioning bad plugged in, and tighten the intermediate connection sets. 7 Tighten the cable gland nut with plate head. 8, check the leads or connections are secure. 9, the connector can be placed on wishful position. WARNING: wiring connector should operate in case of power failure.
