Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a threaded-connection structure is used for the connector, then the connector can be conveniently disassembled and adjusted, but the installation time increases significantly and the cost is much higher
Solution Approach 1:
The connector is divided into a front shell and a rear protective sleeve that can be pre-assembled into a integrated housing. This segmentation allows the complex threaded connection components to be pre-positioned during manufacturing, while the final cable installation only requires simple insertion and crimping, thus maintaining adjustability during production while dramatically reducing field installation time.
Solution Approach 2:
The front shell and rear protective sleeve are pre-assembled with interference fit connections and positioned components during the manufacturing process. This preliminary action ensures that the complex structural adjustments are completed beforehand, so that during actual cable installation, operators only need to perform simple crimping operations without dealing with complex threading or positioning.
2Device complexity
If the connector uses traditional installation structure, then the components are simple, but the clamping force on the cable conductors is insufficient leading to poor dynamic intermodulation performance
Solution Approach 1:
The connector applies different clamping mechanisms to different parts of the cable structure. The cable crimping ring provides localized high-force crimping on the outer conductor, while the center conductor positioning structure provides precise localized clamping on the inner conductor. This local quality enhancement ensures adequate clamping force at critical interfaces without requiring complex overall structure.
Solution Approach 2:
The cable crimping ring uses a circular arc-shaped crimping path that conforms to the cylindrical geometry of the cable outer conductor. This curved crimping approach distributes the clamping force evenly around the circumference, ensuring uniform contact and stable mechanical bonding between the connector and cable, thereby improving dynamic intermodulation performance.
3Device complexity
If the cable outer conductor is partially clamped with large gaps, then the connector structure is simpler, but the mechanical stability deteriorates under dynamic conditions
Solution Approach 1:
The cable crimping ring is designed with optimized dimensional parameters including crimping depth, crimping width, and material hardness. These parameter changes ensure that the crimping force adequately compresses the outer conductor into the cable clamp without excessive deformation, achieving stable mechanical bonding that resists dynamic movements while maintaining a relatively simple overall structure.

AI summary
A RF coaxial cable connector with rapid installation includes a front shell, a rear protective sleeve, a front insulator, a center conductor, a rear insulator, a cable crimping ring, and a cable clamping assembly. The front insulator, the center conductor and the rear insulator are arranged in a front-rear sequence in a cavity of the front shell. The cable crimping ring has a front end surface abutting on an outer ring end surface of a rear end surface of the rear insulator, and is connected with the front shell. The rear protective sleeve is connected with the front shell. The cable clamping assembly is arranged in an inner cavity of the rear protective sleeve, and has a clamping surface formed thereon for clamping on an outer ring surface of an outer conductor of a cable to be connected.
