Plug Connector Latching Hook Geometry for Compact Stable Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connectors lack a compact and stable latching mechanism for securing optical and electrical connections, particularly in high-density arrangements.
Innovation Solution
A latching mechanism is developed using a latching hook with a hook portion having a raised 3D shaped surface region and a non-linear bending line, which securely engages with a latching recess, and is supported by a pretensioned latching arm and actuation device for easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional latching hook with a straight bending line is used, then the manufacturing process is simple, but the latching connection is not compact and lacks stability
Solution Approach 1:
The bending line is designed as a curved line rather than a straight line, creating a non-linear path that forms the hook portion. This curvature enables the hook to engage more effectively with the latching recess, providing stable latching connection while maintaining manufacturability through standard embossing processes.
2Volume of moving object
If the latching hook is made compact with a small hook portion, then the space occupation is minimized, but the durability and strength may be compromised
Solution Approach 1:
A raised 3D shaped surface region is added to the hook portion, creating a multi-dimensional structure. This raised region provides additional engagement surfaces and geometric interlocking features with the latching recess, significantly enhancing the strength and durability of the compact hook without increasing its overall volume.
3Reliability
If the open side of the hook member is constructed at 90° to the surrounding surface, then the manufacturing is straightforward, but the self-locking capability is reduced
Solution Approach 1:
The open side of the hook member is constructed at an angle different from 90° relative to the surrounding surface of the latching arm. This asymmetric angular configuration creates a self-locking mechanism where the geometry of the hook portion naturally resists disengagement, providing reliable latching without requiring complex additional features.
4Stability of the object's composition
If a raised 3D shaped surface region is added to the hook portion, then the engagement stability is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The raised 3D shaped surface region is integrated into the hook portion as a single unified feature formed during the embossing process. By combining the hook geometry and the raised engagement surfaces into one continuous forming operation, the manufacturing complexity is minimized while achieving superior engagement stability.

Function Achieved in This Case
The mechanism provides a compact, durable, and stable latching connection that withstands high withdrawal forces while occupying minimal space, and can be efficiently produced using embossing techniques on metal sheets.
Implementation Method 1
The latching arm is supported between the ends thereof so as to be pretensioned in the manner of an abutment on another element of the first plug connector

AI summary
An electrical and/or optical plug connection has a first plug connector and a second plug connector which can be fit to the first plug connector and which corresponds to the first plug connector. The first and second plug connectors each have a plug face which has a first sheet metal contact and a corresponding second sheet metal contact which can be fit together in an electrically contacting manner. The plug connectors further include first and second optical and/or electrical plug contacts which are fit together and which arranged with spacing from the first and second sheet metal contacts. A latching hook having a latching hook and latching arm is provided on the first plug connector and a corresponding latching recess having a latching edge is provided on the second plug connector. A hook portion (1 of the latching hook is connected to the latching arm via a bending line which deviates from a straight line and has a raised 3D shaped surface region with at least one open side.
