Innovation Solution
The use of clamping blocks with metal or electrically conductive components, which are either soldered or press-fitted onto conductor tracks on the printed circuit board, along with a support ring and metal foil, to create a secure and low-resistance electrical connection for each core of the coaxial cable, allowing for easy assembly and reliable contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing methods are used to electrically connect multi-core coaxial cables to printed circuit boards, then electrical connection is achieved, but the connection process becomes complex and inefficient
Solution Approach 1:
The patent combines multiple functions into a single integrated connector assembly. The clamping blocks serve both as mechanical fastening elements and electrical connection elements, eliminating the need for separate clamping mechanisms and connection terminals. This merging of functions simplifies the overall connection process and reduces the number of assembly steps required.
Solution Approach 2:
The connector assembly is designed to handle multiple cores simultaneously through multiple clamping blocks arranged in a housing. Each clamping block can independently clamp and electrically connect one core, while the entire assembly operates as a unified connection system. This multi-functional design allows a single connector to establish multiple electrical connections in one operation, significantly improving productivity.
2Ease of operation
If simple clamping methods are used, then assembly is easy, but reliable electrical contact with low resistance is compromised
Solution Approach 1:
The clamping blocks are made of electrically conductive material, combining mechanical clamping function with electrical conduction function in a single component. This composite approach ensures that the same element providing mechanical pressure for secure clamping also provides the electrical pathway for reliable low-resistance contact, eliminating the need for separate contact elements that would complicate assembly.
Solution Approach 2:
The clamping blocks are designed to automatically establish electrical contact through their inherent conductive structure. When the clamping blocks secure the cores, the electrical connection is established simultaneously without requiring additional adjustment or separate connection steps. The single-piece design means that proper clamping automatically ensures proper electrical contact, making the system self-regulating and reliable.
3Reliability
If conventional connection methods are used, then electrical connection is established, but high-frequency signal integrity is compromised
Solution Approach 1:
The connector divides the connection task into multiple independent clamping blocks, each handling one core. This segmentation allows each clamping block to be optimized for maintaining the specific geometric and electrical properties needed for high-frequency signals, while the overall assembly remains relatively simple. Each segment can be independently designed to minimize signal distortion and maintain integrity.
Solution Approach 2:
Each clamping block is designed with specific local characteristics optimized for its function: the geometry, material properties, and clamping force distribution are tailored to preserve the electrical and geometric integrity of each individual core. This localized optimization ensures that high-frequency signal requirements are met at each connection point without requiring complex overall system design.
4Reliability
If multiple separate connection elements are used, then reliable contact is achieved, but assembly time and complexity increase
Solution Approach 1:
Multiple clamping blocks are integrated into a single housing assembly, allowing all clamping and electrical connection functions to be performed simultaneously in one assembly operation. The housing provides a unified structure that positions and secures multiple cores together, eliminating the need to perform separate clamping and connection operations for each core individually.
Solution Approach 2:
The clamping blocks are pre-positioned and pre-configured within the housing at their optimal locations for each core. This preliminary arrangement means that during assembly, the cores simply need to be inserted into their designated positions, and the connection is automatically established without requiring complex alignment or adjustment procedures. The pre-configured structure significantly reduces assembly time while maintaining reliable contact.
