Lever Connector Notch and Guide Slope Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lever type connectors require excessive widening of the lever side plate and the use of a jig to align the swing hole and swing fulcrum protrusion, resulting in poor workability during assembly.
Innovation Solution
The design incorporates a notch portion and guide slope on the lever side plate, allowing the swing hole to be easily aligned with the swing fulcrum protrusion by swinging the lever, eliminating the need for a jig and enabling assembly with minimal load, and providing a temporary locking position for smooth connector fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one end side of the lever side plate is bent and opened to fit the swing hole to the swing fulcrum protrusion, then the lever can be mounted on the connector housing, but it requires excessively widening the lever side plate using an exclusive jig, resulting in poor workability of assembly
Solution Approach 1:
The lever side plate is pre-formed with a notch portion and guide slope during manufacturing, so that during assembly the guide slope automatically guides the swing hole to align with the swing fulcrum protrusion without requiring additional jigs or excessive widening operations
Solution Approach 2:
The guide slope acts as an intermediary feature between the lever side plate and the connector housing, facilitating the alignment and insertion of the swing hole into the swing fulcrum protrusion by providing a tapered guiding surface that directs the assembly process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design improves assembly workability by allowing the lever to be assembled without a jig and facilitates easy alignment of the swing hole with the swing fulcrum protrusion, enhancing the efficiency and reliability of the connector fitting process.
Implementation Method 1
a guide slope for guiding the swing hole to be fitted to the swing fulcrum protrusion
Implementation Method 2
a rib protrudes as a fulcrum of a swing operation at the time of mounting the lever on one connector housing by engaging the notch portion with the outside face of the one connector housing

AI summary
Provided is a lever type connector for fitting a connector by a swing operation of a lever 100, in which a notch portion 104 is provided at lever side plates of a substantially U-shaped lever, and it is possible to mount the lever on a male connector housing while swinging the lever about a rib as a fulcrum by engaging the notch portion with a male connector housing rib 14. When swing fulcrum protrusions 16 and 17 and swing holes 106 and 107 are fitted to each other by swinging the lever about the rib as a fulcrum in an inner face of an outer peripheral portion of the lever side plate, the lever side plate is led to be mounted on the swing fulcrum protrusion to promote the lover side plate to open outward. A guide slope 108 thereby guiding the swing holes to be fitted to the swing fulcrum protrusions is provided.
