Wall-Mount Contact Insert Housing With Dual-Side Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachable housings for mounting contact inserts on walls are complex and time-consuming to install, and pre-assembled designs prevent replacement or subsequent installation of contact carriers.
Innovation Solution
An attachable housing with first and second latching elements on its longitudinal sides and end faces, respectively, allowing tool-free mounting of contact inserts from both the connection and plug-in sides, and latching tabs for tool-free attachment to the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten the attachable housing to the wall, then a mechanically strong and reliable connection is achieved, but the mounting process becomes complex and mounting time increases
Solution Approach 1:
The housing is divided into modular components: a wall-mounted housing portion and a contact insert portion. This segmentation allows the housing to be mounted separately on the wall using simple snap-fit latching elements, while the contact insert can be independently installed or replaced, reducing overall mounting complexity while maintaining connection strength
Solution Approach 2:
The latching elements are designed as resilient (spring-loaded) components that dynamically engage with corresponding features on the wall and housing. This dynamic latching mechanism provides strong mechanical connection through elastic force while enabling tool-free, simple installation without requiring threaded fasteners
2Productivity
If a pre-assembled attachable connector is used, then the housing is ready for immediate use, but the contact carrier cannot be replaced or subsequently installed
Solution Approach 1:
The connector is segmented into two independent parts: the wall-mounted housing and the removable contact insert. The housing can be pre-installed on the wall, and the contact insert can be added later or replaced as needed. This segmentation simultaneously enables immediate use (housing ready) and full adaptability (contact insert replaceable)
Solution Approach 2:
The contact insert is designed to nest within the wall-mounted housing. The housing provides a receptacle that receives and secures the contact insert through complementary latching features. This nesting arrangement allows the contact insert to be easily inserted and removed while maintaining a compact, integrated appearance when assembled
3Ease of operation
If the contact insert is inserted from the connection side, then the latching elements can fix the contact insert, but insertion from the plug-in side is not supported
Solution Approach 1:
The latching elements are designed with universal functionality to operate from either direction. Each latching element can engage with corresponding features on the contact insert regardless of which side (connection side or plug-in side) the insert is approached from, enabling flexible installation from either direction while maintaining secure fixation

AI summary
An attachable housing for mounting on a wall having an opening, for receiving at least one contact insert, includes: two opposite longitudinal sides and two opposite end faces, which together enclose a receiving region for the at least one contact insert, the receiving region being open both to a connection side and to an opposite plug-in side, and having a circumferential flange section which, in a mounted state of the attachable housing, lies against the wall. At least one first latching element for latching with a corresponding first mating latching element of the at least one contact insert and at least one second latching element for latching with a corresponding second mating latching element of the at least one contact insert are arranged on a longitudinal side and/or an end face of the attachable housing. The at least one first latching element fixes the at least one contact insert.
