Compact Connector Design for Dense Mounting Challenges
Here’s PatSnap Eureka !
Summary
Problems
Conventional connectors require a large space to disengage locking members from flat conductors, making it difficult to operate when components are densely mounted around the connector.
Innovation solutions
A connector design featuring a housing with a fitting chamber, locking springs, and an unlocking member that allows for easy disengagement by pressing the unlocking member towards the circuit board, eliminating the need for a large displacement space and enabling efficient operation in compact environments.

General conflict description:
Principle concept:
If the engaging portions are displaced in the same direction as the pressing direction of the operating portions, then the locking mechanism is simple in structure, but a large space is required around the connector for operation
Why choose this principle:
The patent changes the displacement direction of the engaging portions from the pressing direction to a direction perpendicular to the pressing direction. When the operating portions are pressed, the engaging portions are displaced in a direction perpendicular to the pressing direction, allowing the flat conductor to be engaged or disengaged without requiring large lateral space around the connector.

Abstract
A connector includes a housing that has a fitting chamber with an insertion opening for a flat conductor in the upper surface thereof and whose lower side is placed on a circuit board, a locking spring that locks the flat conductor, and an unlocking member. The locking spring is provided with a housing fixing portion, an elastic arm that is rotationally displaced about the housing fixing portion away from the flat conductor, an engaging piece that engages with a locking portion of a through-shape provided in the flat conductor, and a sliding contact portion that comes into oblique sliding contact with the unlocking member displaced by a pressing operation, rotates the elastic arm, and extracts the engaging piece from the locking portion.
