Lever Connector Wire Cover Positioning for Slider Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When the wire cover is attached to the housing, the gears of the wire cover can come into contact with the rack teeth of the sliders, causing the sliders to shift from their predetermined positions, which prevents the cam followers of the counterpart connector from fitting correctly.
Innovation Solution
A lever-type connector design that includes a housing, a slider with rack teeth, a wire cover, and a lever with a gear that meshes with the rack teeth. The housing has a fulcrum portion to support the wire cover and a positioning portion that ensures the gear is positioned to mesh with the rack teeth, preventing contact and shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wire cover is attached to the housing without positioning structures, then the assembly process is simple, but the gear may contact the rack teeth and shift the slider position
Solution Approach 1:
The positioning portion is designed to automatically position the gear relative to the rack teeth when the wire cover is attached to the housing. This preliminary positioning action ensures that the gear engages with the rack teeth at the correct position before any slider movement occurs, preventing unwanted position shifts during assembly
Solution Approach 2:
The positioning portion acts as an intermediary element between the wire cover and the slider mechanism. It mediates the relationship by providing a reference surface that ensures proper alignment and positioning of the gear relative to the rack teeth, thereby maintaining manufacturing precision without complicating the assembly process
2Reliability
If the gear is positioned to mesh with the rack teeth during wire cover attachment, then the slider position is maintained, but additional positioning structures are required
Solution Approach 1:
The positioning portion is integrated into the housing structure as a unified component rather than being a separate part. This merging of the positioning function into the existing housing geometry ensures slider position stability while avoiding the need for additional separate positioning structures, thereby maintaining device simplicity
Solution Approach 2:
The housing structure is designed to serve multiple functions: it provides structural support, guides the wire cover attachment, and simultaneously provides the positioning portion that ensures gear-rack alignment. This multi-functionality maintains reliability without increasing device complexity

AI summary
The lever-type connector includes: a housing; a slider having a plurality of rack teeth arranged in a first direction, the slider being movable in the first direction relative to the housing; a wire cover installed on the housing and covering a wire draw-out surface of the housing; and a lever configured to move the slider, the lever being rotatably installed on the wire cover and having a gear meshing with the rack teeth, wherein the housing has a fulcrum portion rotatably supporting the wire cover, and a positioning portion coming into contact with the wire cover and causing the gear to be located at a position at which the gear meshes with the rack teeth.
