Multi-Connected Connector Flush Rear Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-connected connectors with varying connector lengths face misalignment issues in half-inserted states, making it difficult to discriminate without a special member, and the existing structure is costly due to complex equipment.
Innovation Solution
The connector design aligns rear end surfaces of all first connectors flush when fully inserted, with positioning parts adjusted according to each connector's length, allowing half-insertion states to be identified by external protrusion without a special member, simplifying the structure and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a simultaneous fitting detecting member is used to detect half-inserted states, then detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The connector body itself provides the detection function through its structural design. The positioning parts create visible alignment differences that enable self-detection of insertion status without requiring external detecting members. This eliminates the need for separate detection mechanisms while maintaining detection capability.
Solution Approach 2:
The invention uses visual appearance changes (alignment differences) to indicate insertion status. When connectors are fully inserted, their rear end surfaces align flush; when half-inserted, misalignment is visible. This visual indication method replaces complex detecting members with simple observable structural features.
2Ease of manufacture
If all first connectors have the same length, then manufacturing is simplified, but adaptability to different connector requirements is reduced
Solution Approach 1:
The invention applies different lengths to specific connectors based on their individual requirements while maintaining standardized manufacturing processes. Each connector's length is optimized for its specific application, and the positioning parts are adjusted locally to accommodate these variations and ensure proper alignment when fully inserted.
Solution Approach 2:
The invention allows variation in the length parameter of first connectors while maintaining compatibility through adjustable positioning parts. By changing the length parameter of individual connectors and compensating with corresponding positioning part adjustments, the system achieves both adaptability and manufacturing feasibility.
3Difficulty of detecting and measuring
If positioning parts are arranged to align rear end surfaces flush, then visual discrimination of half-inserted states is improved, but positioning precision requirements increase
Solution Approach 1:
The invention divides the positioning function into multiple positioning parts, each associated with specific connector positions. This segmentation allows independent adjustment of each positioning part to accommodate different connector lengths while maintaining overall alignment. The modular approach reduces the precision burden on any single positioning element.
Solution Approach 2:
The positioning parts are designed to be adjustable rather than fixed, allowing dynamic adaptation to different connector configurations. This adjustability compensates for variations in connector lengths and manufacturing tolerances, enabling flush alignment without requiring extremely high positioning precision from the outset.

AI summary
A multi-connected connector 1 includes a plurality of first connectors 110a, 110b, 110c and 110d and a second connector 20 having a plurality of connector fitting chambers 21a, 21b, 21c, 21d arranged in a row in a transverse direction to fit the first connectors. The first connectors include a connector whose length is different from the other connector of the first connectors in a fitting direction of the first connectors. Butting walls 22a, 22b, 22c, 22d as positioning parts that determine fitting completed positions of the first connectors respectively in the connector fitting chambers 21a, 21b, 21c, 21d are arranged in accordance with lengths in the fitting direction of the first connectors to be connected so that rear end surfaces of the plurality of first connectors which are normally completely fitted are aligned so as to be flush.
