Lever-Type Connector Alignment Marks for Assembly Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lever-type connectors require visual alignment and checking of boss fitting holes and retaining protrusions, making the attachment process cumbersome and operator-dependent, lacking ease of alignment and efficient workability.
Innovation Solution
Incorporating alignment marks on both the connector body and lever, such as 'arrow' shaped marks, to facilitate visual alignment and ensure correct positioning of the lever during attachment, allowing for easy alignment and attachment without external positioning jigs, with the lever being rotatably attached to the connector body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If visual alignment checking of boss fitting holes and retaining protrusions is required during attachment, then attachment precision can be ensured, but operator burden increases and workability deteriorates
Solution Approach 1:
Alignment marks are pre-provided on both the connector body and lever before assembly. These marks indicate the correct relative positions of boss fitting holes and retaining protrusions in advance, eliminating the need for operators to perform complex visual alignment checks during attachment. The marks are positioned such that when they align, the boss fitting holes and retaining protrusions are automatically in the correct positions for engagement.
2Device complexity
If no alignment marks are provided, then device complexity is reduced, but attachment alignment becomes difficult and time-consuming
Solution Approach 1:
Alignment marks are provided on both the connector body and lever as simple visual indicators. These marks use color or graphical differences to quickly indicate proper alignment positions, allowing operators to rapidly and easily align components during attachment without complex positioning procedures or specialized tools.

AI summary
A lever-type connector includes a connector body including side walls and a boss portion and a lever including a pair of arm portions, each of the pair of arm portions being provided with a boss fitting hole into which the boss portion of the connector body is to be inserted, the lever being to be rotatably attached to the connector body. The connector body and the lever includes a first and second alignment marks, the first alignment mark and the second alignment mark being visually recognizable while the lever is being attached to the connector body. The lever is, by aligning the second alignment mark with the first alignment mark, to be rotatably attached to the connector body with a position of the boss portion and a position of the fitting hole being aligned with each other, allowing the boss portion to be inserted into the boss fitting hole.
