Segmented Connector Assembly for Narrow Terminal Pitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face challenges in producing a compact and reliable design with narrower spacing between terminals due to integrated terminal and housing structures, making it difficult to precisely deploy a large number of terminals in the molding process.
Innovation Solution
The connector design features half body parts with terminals arranged at a predetermined pitch, integrated with a reinforcing metal fitting and overmolding, where adjacent terminals face opposite directions, and a through hole configuration allowing tail parts to extend outward, enabling a more compact and reliable connector with narrower spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If terminals are integrated with housing using overmolding or insert molding, then connector becomes more compact with narrower spacing between protruding parts, but production becomes more difficult due to difficulty in precisely deploying large number of terminals in mold
Solution Approach 1:
The connector is divided into half body parts, each containing a subset of terminals. This segmentation allows the mold to produce fewer terminals at a time, making terminal deployment more manageable and precise while still achieving a compact overall connector structure when half bodies are assembled together.
Solution Approach 2:
The patent utilizes the width direction dimension by having tail parts extend outward and alternate in direction. This dimensional arrangement allows for more efficient space utilization in the molding process and facilitates easier assembly and production while maintaining compact connector dimensions.
2Length of stationary object
If terminals are integrated with housing, then spacing between protruding parts is reduced, but pitch between terminals becomes narrower making precise deployment difficult
Solution Approach 1:
By dividing the connector into half body parts with fewer terminals each, the molding process can achieve better precision in terminal deployment. Each half body can be manufactured with higher precision, and the overall connector maintains narrow spacing when assembled.
Solution Approach 2:
The tail parts serve as intermediaries that extend outward from the connector body. By positioning tail parts to alternate directions and shift by half-pitch, the design mediates between the need for narrow terminal pitch and the need for precise manufacturing, allowing for easier terminal deployment while maintaining compact dimensions.

AI summary
A connector is provided with a half body part, each of which including a connector main body and a plurality of terminals arranged at a predetermined pitch and integrated with the connector main body by insert molding, a main body end part formed at both ends of the connector main body by coupling the connector main bodies of the half body parts arranged in parallel, and a reinforcing metal fitting integrated with the main body end part.
