Connector Suction Cover Deformation Restraining Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector designs with suction covers can cause breakage of the housing due to the metal inner arms coming into contact with the synthetic resin insulator, leading to structural damage and potential electrical failures.
Innovation Solution
Incorporating a reinforcing member made of metal with a reinforcing plate part that covers the second board opposed surface, along with a flat-plate suction plate part and attachment spring pieces to catch on the connector, and a deformation restraining part to prevent deformation towards the second board opposed surface, thereby preventing the suction plate from breaking the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction cover is used to hold the connector during mounting, then the connector can be securely positioned, but the suction cover may deform and break the housing
Solution Approach 1:
The patent applies beforehand cushioning by introducing a deformation restraining part that prevents the suction cover from deforming excessively during the suction process. This restraining structure acts as a preventive measure before damage can occur to the housing, limiting the suction cover's deformation within safe boundaries that protect the housing from breakage while still allowing sufficient deformation for effective suction and positioning
2Strength
If the suction cover is made of metal for durability, then it can withstand suction forces, but it can cause the synthetic resin insulator to break due to contact
Solution Approach 1:
The patent applies the intermediary principle by introducing a deformation restraining part that acts as a mediator between the metal suction cover and the housing. This restraining structure controls the interaction between the rigid metal suction cover and the more fragile housing, preventing direct harmful contact while allowing the suction cover to maintain its strength and suction functionality

AI summary
A first hold-down includes a reinforcing plate part that covers a CPU board opposed surface. A suction cover includes a flat-plate suction plate part covering an electrical contact spring piece of each contact and thereby able to be sucked by a suction nozzle, a plurality of attachment spring pieces configured to catch on a connector so that the suction plate part is detachable from a connector, and a first main deformation restraining part projecting from the suction plate part toward the CPU board opposed surface in order to inhibit the suction plate part from being deformed toward the CPU board opposed surface in the state where the suction cover is attached to the connector. The first main deformation restraining part is disposed to come into contact with the reinforcing plate part when the suction plate part is deformed toward the CPU board opposed surface.
