FAKRA Angle Connector Force-Free Contact Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-frequency FAKRA right-angle plugs are prone to damaging or bending contact elements during assembly due to the required force, which can also damage the connection between conductors and contact elements.
Innovation Solution
A high-frequency angle connector design featuring an angled holder with recesses and latching lugs that allows contact elements to be inserted laterally without force, with guides and insulating blocks facilitating easy assembly and crimp connections, reducing the risk of damage and enhancing assembly ease, especially for angles greater than 90°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If contact elements are inserted into the holder during assembly of FAKRA right-angle plugs, then the connector is assembled, but force is required that damages or bends the contact elements
Solution Approach 1:
The patent inverts the traditional insertion direction by allowing lateral insertion of contact elements into the holder at an angle (typically 90 degrees) rather than perpendicular insertion. This inversion of the assembly approach eliminates the need for damaging force while maintaining secure contact element positioning within the connector
2Stability of the object's composition
If force is applied during assembly of traditional FAKRA right-angle plugs, then components are secured in place, but the connection between conductors and contact elements is damaged
Solution Approach 1:
The patent transitions from one-dimensional perpendicular insertion to multi-dimensional angular insertion. Contact elements are inserted at an angle (typically 90 degrees) relative to the holder axis, utilizing lateral guides and recesses to achieve stable positioning without applying force that would damage the delicate conductor-contact element connections

AI summary
The invention relates to a high-frequency angle connector, comprising an external connector (100), an angled external conductor part (110), an angled insulating part (120), an angled holder (130) and four angled contact elements (140) to which electrical conductors can be connected. The angled holder (130) is designed such that the four contact elements (140) can be inserted without exerting force. The high-frequency angle connector is preferably a FAKRA connector. The housing (100) of a FAKRA connector corresponds to standard DIN 72594-1.
