Electrical Connector Clip With Releasing Handle For Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with clips for loading electronic packages are inefficient due to offset releasing handles, leading to misalignment and improper orientation during loading, and often require separate handling of the clip and package.
Innovation Solution
A clip design with a frame forming a receiving cavity, featuring pressing sections and latches for secure retention, a releasing handle for foolproof orientation, and alignment notches to ensure correct loading of electronic packages into an electrical connector assembly on a printed circuit board, with a detachable key to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the releasing handle is positioned offset from the latch in the transverse direction, then the clip can be actuated, but the unlatching effect is inefficient and requires torsional operation
Solution Approach 1:
The releasing handle is repositioned from an offset transverse position to a location directly above the latch in the vertical dimension. This dimensional change allows the handle to move linearly upward and downward, eliminating the need for torsional operation and significantly improving unlatching efficiency.
2Manufacturing precision
If the electronic package is loaded separately from the clip, then the loading process is flexible, but the orientation and alignment during loading cannot be ensured
Solution Approach 1:
The electronic package and clip are merged into a single loading unit. The package is positioned within the clip's receiving cavity and secured by latches, ensuring that both components are loaded together in the correct orientation. This combination eliminates the orientation problems associated with separate loading while maintaining operational simplicity.
Solution Approach 2:
The package is preliminarily positioned and oriented within the clip before loading into the connector. The clip's structure, including pressing sections and latches, pre-establishes the correct orientation, so that when the combined unit is loaded, the package is already in the proper position, ensuring manufacturing precision.
3Reliability
If the clip structure is complete with all walls, then the package is securely retained, but interference with the detachable key occurs
Solution Approach 1:
A portion of the clip's wall is removed (taken out) at the location where the detachable key needs to pass through or engage. This extraction creates clearance for the key operation while the remaining wall structure maintains sufficient retention reliability for the package.
Solution Approach 2:
The clip structure is modified with local quality changes: specific sections of the walls are removed or thinned only in the areas where key interference occurs, while other portions maintain full thickness for retention. This localized modification preserves overall reliability while enabling key compatibility.
4Manufacturing precision
If the releasing handle is positioned within the seat opening above the printed circuit board, then foolproof orientation is achieved, but the handle position is constrained
Solution Approach 1:
The releasing handle's position within the seat opening above the printed circuit board serves a dual purpose: it provides the mechanical function of actuating the latch and simultaneously serves as a foolproof mechanism by physically constraining the loading orientation. The handle's location self-enforces the correct loading direction, eliminating the need for additional orientation features.

AI summary
An electrical connector includes an insulative housing retaining a plurality of contacts therein and surrounded by a metallic seat. A clip includes a frame with corresponding four walls to commonly form a receiving cavity to receive the electronic package therein, and each wall forms a pressing section to downwardly press an upward surface of the electronic package. A pair of latches are formed on a lower side of the frame to cooperate with the pressing sections of the walls to retain electronic package within the receiving cavity to be wholly a sub-assembly for being commonly received within the electrical connector. The clip includes a releasing handle to actuate the corresponding latch, and the releasing handle is positioned in an opening of the seat and intimately above the printed circuit board to function as a foolproof mechanism for loading the electronic package in a right orientation.
