D-subminiature Connector Assembly with Resilient Latch Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing D-subminiature connectors face challenges when installed in space-limited locations, such as custom cabinetry and surface mount electrical boxes, due to deficiencies in design and installation constraints, particularly in low-voltage electronic systems integration industries like home theater and audio visual settings.
Innovation Solution
The development of a D-subminiature connector assembly with a base, header, and terminal block configuration that includes a substrate with printed circuit board integration, allowing for secure attachment to a housing with resilient latch members and panel mounts, enabling efficient electrical connection and space optimization.

Engineering Contradiction Analysis
1Volume of moving object
If traditional D-subminiature connectors are installed in space-limited locations, then installation flexibility is reduced, but the connectors still need to provide reliable electrical connection
Solution Approach 1:
The connector assembly is divided into separate functional components: a D-subminiature connector portion for electrical connection and a housing portion with resilient latch members for mechanical attachment. This segmentation allows each component to be optimized independently - the connector for reliability and the housing for space efficiency.
Solution Approach 2:
The resilient latch members are disposed within the housing structure, with at least one latch member positioned inside the housing cavity. This nesting arrangement maximizes space utilization by placing attachment mechanisms within the existing housing volume rather than adding external bulk.
2Reliability
If resilient latch members are added to secure the connector, then attachment reliability improves, but the housing complexity increases
Solution Approach 1:
The resilient latch members are designed to automatically engage with the connector upon insertion and provide self-locking functionality. The resilient nature of the latches allows them to deform during installation and then maintain constant contact pressure, providing secure attachment without requiring additional fastening operations or complex mechanisms.
3Length of stationary object
If the housing height is reduced to fit constrained environments, then space efficiency improves, but the connector accessibility may be compromised
Solution Approach 1:
The housing is designed with an open top configuration rather than enclosing all sides, creating accessibility in the vertical dimension while maintaining reduced height. The resilient latch members are positioned to engage from the sides or bottom, allowing secure attachment even with the open-top, low-profile design that facilitates connector access.

AI summary
In one exemplary embodiment, an electrical connector including a D-subminiature connector assembly that includes a base; a D-subminiature connector mounted to the base; and a header mounted to the base. The header has a plurality of internal contacts and an open rear end for receiving a receptacle that includes conductive contacts that are electrically connected to the internal contacts when the receptacle is fully inserted into and engaged with the header.
