Electrical Connector Fixing Member Guide Chip Module Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for chip modules often damage conducting terminals during assembly due to inaccurate alignment, as the locking portion of the carrier collides with the conducting terminals when manually assembled.
Innovation Solution
The design incorporates a fixing member with extending portions and a stop wall that guides the chip module to prevent collision with conducting terminals, ensuring accurate alignment and reducing the risk of damage by maintaining the conductive connection surface away from the contact portion during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the locking portion of the carrier cooperates with the side wall of the insulating body and the inclined surface is disposed on the side wall, then the structure can support the locking portion, but the structure of the insulating body needs to be changed and alignment accuracy decreases during manual assembly
Solution Approach 1:
The patent introduces a separate guiding structure as an intermediary component between the carrier and the insulating body. This guiding structure provides the inclined surface for the locking portion without requiring modifications to the insulating body's side wall, thereby maintaining alignment accuracy during manual assembly while still providing structural support.
Solution Approach 2:
The patent divides the guiding and supporting functions into separate components: the insulating body maintains its original structure, while a separate guiding structure is introduced to provide the inclined surface and alignment guidance. This segmentation prevents the need to change the insulating body structure and maintains manufacturing precision.
2Ease of operation
If manual assembly is used, then ease of operation is improved, but alignment accuracy decreases causing collision with conducting terminals
Solution Approach 1:
The patent designs the guiding structure with an inclined surface that automatically guides the locking portion into the correct position during manual assembly. The structure itself provides the alignment guidance, eliminating the need for high operator skill or precision tools, thus maintaining ease of operation while improving alignment accuracy.
Solution Approach 2:
The guiding structure acts as an intermediary that mediates between the operator's manual assembly actions and the precise positioning requirement. It provides physical guidance through the inclined surface, ensuring accurate alignment even during simple manual assembly operations.
3Productivity
If the locking portion enters the accommodating cavity during assembly, then assembly is completed, but the conducting terminals are damaged due to collision or hooking
Solution Approach 1:
The patent employs preliminary anti-action by providing a guiding structure with an inclined surface before the locking portion enters the accommodating cavity. This guiding structure pre-aligns the locking portion, preventing collision or hooking of the conducting terminals during the assembly process, thus eliminating terminal damage while maintaining assembly completion.
Solution Approach 2:
The guiding structure performs preliminary alignment action on the locking portion through its inclined surface before the locking portion reaches the accommodating cavity. This preliminary positioning action ensures that the locking portion enters the cavity correctly without damaging the conducting terminals.

AI summary
An electrical connector for connecting a chip module, includes an insulating body, multiple conducting terminals received in the insulating body, and a fixing member having a base for fixing the chip module. The insulating body has an accommodating cavity that is rectangular and opened upward. A stop wall projects upward from each of four corners of the accommodating cavity. Each conducting terminal has a contact portion extending upward for electrically contacting a conductive connection surface of the chip module. The contact portions are located in the accommodating cavity and do not exceed the stop wall upward. The base is assembled above the insulating body. Four extending portions extend downward from the base and are assembled at an outer side of the stop walls. An inner side of each extending portion is provided with a guiding inclined surface cooperating with the outer side of the stop wall.
