Socket With Depression Portions For Planarity Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face challenges in reducing size while maintaining accurate planarity inspection of socket contact members, as reducing the protrusion length of socket contact members compromises the overlapping amount needed for effective inspection.
Innovation Solution
The socket design incorporates depression portions on its side walls, allowing socket contact members to protrude through these depressions, which enables increased accuracy in planarity inspection even with reduced protrusion length, by forming these depressions continuously or independently along the longitudinal direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the protrusion length of socket contact members is reduced to decrease the width of the socket, then the size of the connector is reduced, but the overlapping amount between socket contact members and inspection jigs becomes insufficient, making accurate planarity inspection impossible
Solution Approach 1:
The patent introduces a depth dimension by forming depression portions in the side walls of the socket body. These depression portions create an overlapping region between the socket contact members and inspection jigs in the depth direction, allowing accurate planarity inspection even when the protrusion length is reduced. This dimensional approach resolves the contradiction by adding a new spatial dimension for inspection overlap.
Solution Approach 2:
The depression portions act as intermediary structures that facilitate the inspection process. By creating recesses in the side walls, they provide a controlled environment where inspection jigs can effectively contact and measure the planarity of socket contact members, even with reduced protrusion length. The depression portions mediate between the reduced size requirement and the inspection accuracy requirement.
2Volume of moving object
If the protrusion length of socket contact members is reduced to decrease the width of the socket, then the size of the connector is reduced, but the stability of the connection state between the socket and printed wiring boards becomes unstable
Solution Approach 1:
The depression portions in the side walls create an additional depth dimension that allows for better mechanical interlocking between the socket contact members and the printed wiring board. This depth-based structure provides enhanced connection stability even when the horizontal protrusion length is reduced, resolving the contradiction between size reduction and connection reliability.
3Volume of moving object
If the width of the socket is reduced by decreasing the protrusion length of socket contact members, then the connector size is reduced, but the inspection process becomes more difficult and less accurate
Solution Approach 1:
By introducing depression portions in the depth direction, the patent creates an accessible region for inspection jigs to contact the socket contact members. This dimensional approach makes inspection easier and more accurate despite the reduced width, as the depression portions provide a controlled measurement environment.
Solution Approach 2:
The depression portions are pre-formed in the socket body structure, preparing the inspection surface in advance. This preliminary structuring of the side walls with recesses facilitates the subsequent inspection process, making it easier to access and measure the socket contact members without requiring large protrusion lengths.

AI summary
A socket includes a substantially rectangular columnar socket body made of an insulating material and the socket body including a connection recess portion defined on one surface thereof. Side walls opposed to each other in a transverse direction and lead-out pathways formed in the side walls. The socket further includes a plurality of socket contact members arranged side by side within the connection recess portion along a longitudinal direction. One-end portions of the socket contact members extend through the lead-out pathways and protruding outwards beyond an outer surface of at least one of the side walls of the socket body. The socket body includes a depression portion formed on the side wall through which the socket contact members protrude and the depression portion being formed at least around the socket contact members.
