Compact Electrical Connector Design for Miniaturized Electronics
Here’s PatSnap Eureka !
Summary
Problems
Conventional electrical connectors have large and complex locking mechanisms, limiting their application in miniaturized, integrated, and multi-functional electronic products due to the need for sufficient distance between the connector and other elements.
Innovation solutions
The design includes a housing with a pivotably mounted locking arm, a biasing member, and a sliding member that interacts with the locking arm to facilitate easy mating and unmating, allowing for a compact and reliable electrical connection without the need for extensive space, utilizing a cam surface and hook mechanism for secure locking.

General conflict description:
Principle concept:
If a conventional locking mechanism is used in electrical connectors, then the connector can achieve reliable locking, but the connector size increases and requires sufficient distance from other elements
Why choose this principle:
The locking arm is nested within the housing structure, with the intermediate portion rotatably connected to the housing and the first end extending into the groove. This nesting arrangement allows the locking mechanism to be compact while maintaining sufficient locking force, as the locking arm可以利用 the housing structure for support rather than requiring separate external components.
Principle concept:
If a conventional locking mechanism is used in electrical connectors, then the connector can achieve reliable locking, but the connector size increases and requires sufficient distance from other elements
Why choose this principle:
The locking mechanism transitions from a linear extension to a rotational dimension. The intermediate portion of the locking arm rotates about a pivot point to engage and disengage the locking portion from the groove, enabling compact packaging of the locking function without requiring linear space extension.

Abstract
An electrical connector and a method for mating and unmating the same. The electrical connector comprises a housing, a locking arm, a biasing member, and a sliding member. The locking arm comprises a first end, a second end, and an intermediate portion between the first end and the second end. The first end comprises a locking portion. The intermediate portion is pivotably mounted to the housing about a pivot. The biasing member is engaged with the locking arm to drive the first end in a first direction. The sliding member is slidably connected to the housing and configured to slide in a second direction perpendicular to the first direction. The electrical connector may be securely locked to a mating electrical connector and has a compact structure, allowing the mating electrical connector to be mounted on a circuit board that has a compact structure.
