Angled Pin Filtered Header Assembly for Compact Electrical Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtered connection headers for electronic devices are typically tall due to straight contact pins and filtering mechanisms, making them impractical for mass manufacturing and space-efficient design.
Innovation Solution
A filtered connection header assembly with angled pins and a filter assembly secured to the external surface of the housing, featuring a pin stabilizer and connector shroud for alignment and sealing, allowing for a lower profile and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straight contact pins are used to extend vertically from the PCB to the connection header, then reliable electrical connection is achieved, but the connection header assembly becomes relatively tall
Solution Approach 1:
The contact pins are bent at a 90-degree angle, changing their orientation from vertical to horizontal. This dimensional change allows the pins to extend horizontally from the PCB through the housing wall to engage with the mating connector, thereby reducing the vertical height of the connection header assembly while maintaining electrical connection reliability
2Reliability
If filtering mechanisms are secured within the housing adjacent to the PCB, then signal filtering is achieved, but the housing becomes relatively tall
Solution Approach 1:
The filtering mechanism is extracted from its traditional position within the housing adjacent to the PCB and relocated to the exterior surface of the housing. The filter assembly is mounted on the outer surface, allowing signal filtering functionality to be maintained while eliminating the need for additional vertical space within the housing
3Length of moving object
If complex rearrangement of filter and contact pins is attempted to reduce height, then space is minimized, but assembly complexity increases making mass manufacturing impractical
Solution Approach 1:
The connection header assembly is segmented into distinct functional components: the PCB with bent pins, the housing with exterior-mounted filter assembly, and the mating connector. This segmentation allows each component to be manufactured and assembled independently in a straightforward sequence, reducing assembly complexity while achieving the height reduction goal through the bent pin configuration

AI summary
A filtered electrical connection header assembly for an electrical device, and methods for assembling a filtered connection header assembly for an electrical device, are disclosed. An electrical connection header may include a housing for an electrical circuit and a connection header assembly secured to the housing that includes a plurality of electrical pins. The pins may each include a first portion, and a second portion oriented generally orthogonal to the first portion. The second portions of the pins extend into the housing to contact the electrical circuit. A forward end of a connector shroud may receive a pin stabilizer having a plurality of apertures that receive the first portion of the pins for engagement with a mating connector. The electrical connection header may further include a filter assembly configured to filter a signal transmitted though the pins that is secured to the external surface of the housing.
