Cost-Effective Connector Design with Integrated Shielding
Here’s PatSnap Eureka !
Summary
Problems
The existing surface-mounting receptacle connector structures require a shield member on each receptacle contact, leading to a complicated structure and high manufacturing costs.
Innovation solutions
A connector design where the contact and housing are integrated by insert molding, featuring a metal base with a fixed part and projecting parts, an insulating layer, and conductive patterns, with the base's opposed-to-board surface exposed for soldering to a ground pattern, enhancing signal characteristics at a lower cost.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a shield member is formed on the periphery of each receptacle contact, then signal characteristics are improved, but the structure becomes complicated and manufacturing cost increases
Why choose this principle:
The patent merges the shield member function with the housing structure by making the housing itself conductive. The housing is formed with a conductive layer that serves both as the housing body and as the shield member, eliminating the need for separate shield components while maintaining signal shielding effectiveness
Principle concept:
If a shield member is formed on the periphery of each receptacle contact, then signal characteristics are improved, but the structure becomes complicated and manufacturing cost increases
Why choose this principle:
The housing is designed to perform multiple functions simultaneously: it provides mechanical support, electrical insulation (through insulating resin), and electromagnetic shielding (through the conductive layer). This multi-functional design eliminates the need for separate dedicated shield members for each contact

Abstract
A base includes a lower surface opposed to a lower board on which a receptacle is surface-mounted. The lower surface includes a solder connection part exposed toward the lower board without being covered with a housing so that it is soldered to a ground pattern of the lower board. This structure improves signal characteristics of a contact at low cost in a surface-mounting connector where the contact and the housing are integrated by insert molding. The signal characteristics of each conductive pattern are thereby improved at low cost.
