Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors face issues with high-frequency signal transmission due to susceptibility to noise interference, poor grounding effects, and increased manufacturing costs and time, primarily because of gaps between metal grounding parts and terminals, leading to signal attenuation and reduced efficiency.
Innovation Solution
The design includes conductive terminals with signal and grounding terminals, where conductive glue is used to electrically connect the grounding terminals, filling openings in insulation bodies and being sandwiched between insulation bodies and casing to ensure stable adhesion and effective shielding, reducing crosstalk and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal grounding parts are used to connect grounding terminals, then grounding effect is improved, but manufacturing cost and production time increase
Solution Approach 1:
The patent combines the grounding terminal and the insulation body into a single integrated structure. The grounding terminals are directly formed as protrusions on the insulation body, eliminating the need for separate metal grounding parts and their associated stamping and bending processes. This merging reduces manufacturing complexity while maintaining grounding effectiveness.
Solution Approach 2:
The insulation body itself serves the dual function of electrical insulation and grounding terminal support. By forming grounding terminals directly on the insulation body, the structure uses its own material and geometry to provide grounding functionality, eliminating the need for additional dedicated grounding components.
2Reliability
If metal grounding parts are used to connect grounding terminals, then grounding effect is improved, but manufacturing time increases
Solution Approach 1:
The grounding terminals are integrated into the insulation body manufacturing process. Both components are formed in a single molding operation, eliminating the need for separate manufacturing steps for metal grounding parts and their subsequent assembly. This significantly reduces production time.
Solution Approach 2:
The grounding terminals are pre-formed as part of the insulation body structure during the molding process. This preliminary formation of grounding terminals eliminates the need for subsequent assembly operations, reducing overall manufacturing time while ensuring proper grounding connections from the start.
3Reliability
If grounding terminals are connected with metal grounding parts, then shielding effect is improved, but contact surface gaps cause poor grounding
Solution Approach 1:
The grounding terminals are formed as integral parts of the insulation body, ensuring continuous and gap-free contact surfaces. This integration eliminates alignment issues between separate metal grounding parts and grounding terminals, providing reliable shielding without manufacturing precision problems.
Solution Approach 2:
The grounding terminals and insulation body are made from the same material through a single molding process, ensuring homogeneous properties throughout. This homogeneity guarantees consistent electrical characteristics and reliable grounding connections without the interface problems that arise from joining dissimilar materials.
