Cable Compatibility
Leaky Feeder Range: Engineered to match standard corrugated outer conductor dimensions of 7/8 inch, 1-1/4 inch, and 1-5/8 inch leaky cables.
Outer Conductor Fit: Precision-machined clamping mechanism secures the corrugated outer conductor of leaky cables without crushing the shield.
Dielectric Core Alignment: Internal pin dimensions align directly with the inner conductor of specified cable sizes to maintain a continuous transmission path.
Jacket Sealing: Gasket dimensions match the outer jacket diameters of standard leaky feeder cables to prevent moisture ingress at the cable entry point.
Applicable Leaky Cable Systems
Underground Tunnel Communications: Utilized in mining tunnels and underground railway systems where standard radio propagation is blocked.
In-Building Wireless Coverage: Deployed in multi-story buildings and subways to distribute two-way radio and emergency communication signals.
Industrial Safety Networks: Serves hazardous or confined industrial sites requiring continuous radio coverage along defined pathways.
Distributed Antenna Systems (DAS): Integrated into leaky feeder infrastructure to extend wireless coverage zones for cellular and public safety bands.
Construction & Cable Termination
Straight N-Type Male: Straight-body configuration with an N-type male equipment interface and dedicated leaky cable termination.
Cable Retention: A mechanical clamping ring secures the cable outer conductor and armor, while metal contact rings maintain shield continuity and grounding.
Sealing: Compressed O-rings seal against the cable jacket, with an IP68 sealing class for sealed cable connection requirements.
Center Conductor: The solderless, crimp-free center pin inserts directly into the cable inner conductor and is secured by set-screw or spring contact.
Inspection & Quality Control
Dimensional Inspection: Thread tolerance, pin diameter, and body dimensions are checked using calibrated gauges and measuring tools to verify dimensional conformity.
Electrical Testing: Connectors undergo checks for center and outer contact resistance, insulation resistance, and dielectric withstand voltage against the specified limits of ≤1.00 mΩ, ≤0.25 mΩ, ≥5000 MΩ, and 2500 Vrms AC.
RF & Sealing Verification: Insertion loss and VSWR are verified against applicable specifications, while IP68 versions undergo sealing tests before shipment.
Material Traceability: Brass/bronze components and plating specifications are verified against applicable material and compliance documentation for batch traceability.
FAQ
Q: What is the typical lead time for standard volume orders of these connectors?
A: Production lead time generally ranges from 7 to 15 working days depending on the specific cable size variants and order quantities.
Q: Can you provide customized plating options, such as white bronze instead of standard nickel, for corrosive environments?
A: Yes, alternative metal platings can be applied based on specific salt spray resistance requirements or project specifications.
Q: What is the minimum order quantity for custom-branded packaging or laser-etched part numbers?
A: Custom laser marking and packaging requirements depend on batch volumes, and specific MOQ details can be discussed during quotation.
Q: How are these connectors packaged for transit?
A: Each connector is individually bagged and packed in compartmentalized cartons to protect threads and sealing rings during international shipping.
Q: Are sample units available for laboratory evaluation before placing a bulk purchase?
A: Sample pieces can be provided for testing and evaluation, with shipping costs typically managed according to client preference.
Q: What is your standard payment term for new overseas business accounts?
A: Standard transactions are commonly processed through telegraphic transfer (T/T) with deposit terms agreed upon during contract review.
