Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical receptacle connector housings lack sufficient structural strength, leading to deformation or breakage during heating and stressing, which can result in open circuits due to inadequate support for the grounding plate and contacts.
Innovation Solution
A receptacle connector design featuring a housing with a cross-shaped supporting structure, including first and second dividing plates and a supporting strip, which wraps around the contact assembly to provide uniform support and maintain electrical connections, enhancing structural integrity and bonding stability during the injection and filing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a typical housing structure is used to constrain the contact assembly, then the device complexity is reduced, but the structural strength and reliability are insufficient leading to deformation or breakage during heating and stressing
Solution Approach 1:
The housing is segmented into multiple functional components: a base wall, a receiving space, and multiple supporting strips extending in different directions. These segmented structures work together to provide comprehensive support to the contact assembly, distributing mechanical stresses and preventing deformation while maintaining manufacturing feasibility.
Solution Approach 2:
Supporting strips are extended in multiple dimensions (first direction, second direction perpendicular to the first direction, and third direction) to provide three-dimensional support to the contact assembly. This multi-dimensional support structure enhances structural strength by constraining the contact assembly from multiple directions, preventing deformation during heating and stressing processes.
2Stability of the object's composition
If the housing surrounds the insulative carrier and base completely, then the structural integrity is improved, but the manufacturing precision and bonding stability deteriorate during injection and filing processes
Solution Approach 1:
The housing structure is divided into modular segments including the base wall, receiving space, and multiple supporting strips. This segmentation allows for controlled bonding interfaces during injection molding, improving manufacturing precision while maintaining overall structural integrity through the coordinated arrangement of these segments.
Solution Approach 2:
Different regions of the housing are designed with specific local qualities: the base wall provides foundational support, the receiving space accommodates the contact assembly with precise dimensions, and the supporting strips are strategically positioned to provide localized reinforcement. This local optimization ensures both structural integrity and manufacturing precision in different areas.
3Ease of manufacture
If the housing provides minimal support to the contact assembly, then the ease of manufacture is improved, but the reliability deteriorates due to open circuits from grounding plate and contact deformation
Solution Approach 1:
The supporting strips are designed to dynamically respond to thermal and mechanical stresses during manufacturing and operation. These strips flexibly accommodate expansion and contraction of the contact assembly during heating processes while maintaining sufficient constraint to prevent deformation that would cause open circuits, thus ensuring reliability without overly complicating manufacturing.

AI summary
A receptacle connector includes a contact assembly and a housing. The contact assembly includes first contacts and second contacts extending along a first direction. A first insulative carrier and a second insulative carrier respectively wraps the wrapping regions of the first contacts and the second contacts. The housing includes a receiving space for connecting with the plug connector. The housing includes a first sidewall, a second sidewall, a first end wall, a second end wall, a supporting strip and dividing plates which defined the receiving space. The supporting strip extends along the first direction, and two ends of the supporting strip are respectively connected with the first end wall and the second end wall. The first dividing plate and the second dividing plate respectively extend from the first side wall and the second side wall toward the receiving space and are connected with the supporting strip.
