中文简体BNC RF Coaxial Connectors for semi-flexible and semi-rigid cable Manufacturer
Product Overview
Designed specifically for semi-flexible and semi-rigid coaxial cables, the BNC connectors deliver stable, low-loss RF performance in space-constrained assemblies where cable routing flexibility and mechanical rigidity must coexist. Semi-rigid cables are constructed with a solid outer conductor—typically copper—that maintains a fixed shape after bending, while semi-flexible cables offer controlled flexibility through a spiral-wound outer conductor. Both demand precision-machined connectors to preserve impedance continuity at the interface.
Founded in 1999, Yangzhou Jingcheng Electronics has accumulated over two decades of specialized manufacturing experience for this demanding connector category, investing in Korean Hanwha CNC machining centers and U.S. Agilent network analyzers to guarantee consistent dimensional accuracy and electrical performance across every batch.
Key Features
Precision-machined center contacts maintain controlled impedance transition between cable and connector, minimizing reflection losses at signal-critical junctions.
Available in both 50Ω and 75Ω versions to support the full range of system impedance requirements—from RF test equipment (50Ω) to video distribution infrastructure (75Ω).
Bayonet coupling mechanism provides positive locking with tactile confirmation, preventing accidental disconnection in vibration-prone installations such as avionics test benches and mobile platforms.
Silver or gold plating options on contact surfaces ensure low contact resistance, excellent corrosion resistance, and long service life even in humid or salt-spray environments.
Compatible with standard semi-rigid cable diameters (e.g., 0.047", 0.085", 0.141") and common semi-flexible cable types, offering broad application coverage without adapter requirements.
Straight, right-angle, and bulkhead configurations available to accommodate diverse PCB layouts and panel-mount requirements.
Competitive Advantages
Source Factory Pricing: As a direct manufacturer established in 1999, Jingcheng eliminates distributor markups, offering OEM and volume buyers a significant total-cost-of-ownership advantage compared to reseller-sourced alternatives.
Tri-Standard Certification: ISO9001 quality management, ISO14001 environmental management, and GJB9001A military-grade quality system certifications—plus RoHS compliance
Customization Capability: The in-house engineering R&D center can modify connector geometry, plating, and cable termination style to match customer-specific requirements, reducing development cycles from weeks to days.
Consistent Batch Quality: Near-200 advanced CNC machines and dedicated inspection stations with network analyzers guarantee electrical parameter consistency batch-to-batch, critical for production line continuity.
Rapid Delivery: Efficient supply chain management within Yangzhou National Economic & Technology Development Zone enables fast turnaround from order confirmation to shipment, serving customers in the US, Japan, Germany, Vietnam, and beyond.
Typical Applications
RF test and measurement cable assemblies in laboratory environments
Avionics and defense subsystem interconnects requiring stable impedance under vibration
Medical imaging equipment internal RF routing (MRI, CT, ultrasound)
Telecom base station feeder and distribution cabling
Industrial wireless sensing and control system cabling
FAQ
Q: What cable outer diameters are supported for semi-rigid cable terminations?
A: Our BNC Connectors for semi-flexible and semi-rigid cable are tooled to support the most common semi-rigid cable ODs including 0.047", 0.085", and 0.141" (UT-047, UT-085, UT-141). Custom tooling for non-standard diameters is available upon request with a typical lead time of 2–3 weeks.
Q: Is it possible to obtain both 50Ω and 75Ω versions of the same connector body style?
A: Yes. Both impedance variants share the same mechanical envelope but use matched center contact and dielectric geometries optimized for each impedance. Please specify the required impedance when placing an order or requesting a sample.
Q: What surface plating is standard, and are alternatives available?
A: Standard offerings include silver-plated and gold-plated contact surfaces over a nickel barrier. Gold plating is recommended for applications with low mating cycle counts but stringent contact resistance requirements; silver is cost-effective for moderate-frequency, higher-cycle applications. Custom plating thickness and alternative finishes are negotiable for volume orders.
