Plug Connector Housing Frame for Stable Locking Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plug connector housings face issues with instability and vulnerability to mechanical stress, leading to potential collapse or misalignment, and lack effective protection against improper insertion and contact.
Innovation Solution
The housing incorporates a frame part that spans the weakened material tongue and cutaway sections, providing additional stability and preventing collapse while allowing secure locking and insertion of the mating plug connector, with the frame part acting as a stop to limit excessive deflection of the locking tab.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking tabs are formed as separated material tongues with cutaway sections, then the locking function is improved, but the stability of the housing is worsened
Solution Approach 1:
The locking tab is segmented from the circumferential wall through cutaway sections, creating a separated material tongue that can independently deflect and lock while the frame part remains integrated to maintain housing stability
Solution Approach 2:
The frame part merges the separated material tongue and cutaway sections into a unified stabilizing structure that prevents housing collapse while allowing the locking tab to function independently
2Ease of operation
If material tongues are separated from circumferential walls, then locking capability is improved, but mechanical resistance is worsened
Solution Approach 1:
The material tongue is segmented from the circumferential wall to enable independent locking action, while the frame part compensates for the weakened structure by providing additional mechanical support
Solution Approach 2:
The frame part acts as an intermediary structure that bridges the separated material tongue and the circumferential wall, transferring and distributing mechanical loads to prevent housing deformation
3Stability of the object's composition
If frame part spans the material tongue and cutaway sections, then housing stability is improved, but device complexity is worsened
Solution Approach 1:
The frame part is merged with the circumferential wall as a single integrated component, eliminating the need for separate fastening operations and reducing assembly complexity despite the added structural feature
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances mechanical resistance, prevents housing deformation, and ensures secure locking and proper insertion, while maintaining ease of use and reducing the risk of damage.
Implementation Method 1
The locking tab can be elastically deflectable in a direction perpendicular to the insertion direction of the mating plug connector when inserting the mating plug connector into the plug chamber

AI summary
A housing of an electrical plug connector, which has the following features: at least one plug chamber, accessible from a plug face of the plug connector, into which a mating plug connector designed as the mating piece for the plug connector may be inserted; four circumferential walls, which surround at least the plug chamber on the circumferential side and extend in parallel to an insertion direction, in which the mating plug connector may be inserted into the plug chamber; at least one elastically resilient locking tab is formed on at least one circumferential wall for the purpose of locking the mating plug connector on the plug connector; the at least one locking tab is designed as a material tongue separated from the material of the circumferential wall by cutaway sections on both sides. An electrical plug connector is also provided, which includes the housing.
