Conductive Plastic Block Integral Molding for Connector Stability
Solution Overview
Problem
Existing electrical connectors with conductive plastic blocks tend to loosen when assembled, compromising the steadiness of the terminal base, which affects the reliability of high-frequency signal transmission.
Innovation Solution
An electrical connector design where the conductive plastic block is integrally molded with the insulative housing, ensuring a seamless and secure electrical connection with grounding contacts, preventing loose assembly and enhancing the steadiness of the terminal base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive plastic blocks are assembled in the insulative housing, then the signal contacts are shielded and electrical properties are improved, but the conductive plastic blocks may loosen during assembly
Solution Approach 1:
The conductive plastic block and insulative housing are merged into a single integrated component through integral molding. This eliminates the separate assembly step that caused loosening, while maintaining the shielding function of the conductive block and the structural support of the insulative housing as unified structural features
2Ease of manufacture
If conductive plastic blocks are assembled separately in the insulative housing, then the manufacturing process is simpler, but the terminal base becomes less steady
Solution Approach 1:
The conductive plastic block and insulative housing are merged into a single integrated component through integral molding. This eliminates the separate assembly step that caused loosening, while maintaining the shielding function of the conductive block and the structural support of the insulative housing as unified structural features

AI summary
An electrical connector includes a terminal base and plurality conductive contacts, and the conductive contacts defining a first group of contacts, and the first group of contacts including several signal contacts and several grounding contacts arranged with the signal contacts at intervals. The terminal base includes an insulative housing, and a conductive plastic block integrally molded with the insulative housing and combining with the insulative housing seamlessly, the conductive plastic block electrically contacts with the grounding contacts to electrically connect the grounding contacts together. Therefore, the seamless state prevents any loose from the conductive plastic block and the insulative one, which could make the terminal base to be steadier.
