Vehicle Radar Connector Housing for Stable Multi-Angle Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On-vehicle radar apparatuses face challenges in maintaining connector orientation stability due to vehicle vibrations and the need for versatile mounting configurations for automatic driving applications, where connectors may change orientation depending on mounting locations, and external forces can alter their position.
Innovation Solution
The design incorporates a common case and cover configuration that supports printed circuit boards with radar antenna units, featuring inclined surfaces and snap-fit connections to maintain connector orientation and prevent external force-induced changes, while allowing for adjustable mounting angles and enhanced waterproofing through sealing grooves and flange portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connector orientation is made variable to accommodate different mounting locations, then the adaptability of the radar apparatus is improved, but the stability of the connector orientation deteriorates due to external forces like vibration
Solution Approach 1:
The connector is designed with rotational freedom to adapt to different mounting orientations (0°, 90°, 180°, 270°), allowing the radar apparatus to be mounted flexibly on various vehicle surfaces. The connector can rotate to align with the cable direction while the case maintains a fixed structure for stable mounting.
Solution Approach 2:
The connector is separated into a fixed portion attached to the case and a rotatable portion that can independently adjust its orientation. This segmentation allows the connector to adapt to different mounting locations while maintaining stable connection to the case, resolving the contradiction between adaptability and stability.
2Reliability
If the connector is fixed rigidly to maintain orientation stability, then the reliability is improved, but the ease of installation deteriorates due to limited mounting angle options
Solution Approach 1:
The connector incorporates a rotatable mechanism that allows it to assume multiple stable orientations (0°, 90°, 180°, 270°) relative to the case. This dynamic capability enables installers to choose the most convenient mounting angle while maintaining reliable connections, thus improving ease of installation without compromising reliability.
Solution Approach 2:
The connector's orientation parameter can be changed to four discrete angles, providing installation flexibility. The connector maintains reliable electrical connection across all orientations through its rotatable design, resolving the contradiction between fixed reliability and flexible installation.
3Ease of operation
If the connector can rotate freely to adapt to cable directions, then the ease of operation is improved, but the manufacturing precision deteriorates due to potential misalignment
Solution Approach 1:
The connector is designed with controlled rotational freedom at four specific orientations (0°, 90°, 180°, 270°), allowing easy alignment with cable directions during operation. The rotatable mechanism includes positioning features that ensure precise alignment at these discrete angles, preventing misalignment while maintaining operational ease.
Solution Approach 2:
The connector orientation is quantized to four discrete angular positions, providing ease of operation for cable connection while maintaining manufacturing precision. The discrete angular positions are designed with的定位 features that ensure accurate alignment, resolving the contradiction between operational flexibility and alignment precision.

AI summary
An on-vehicle radar apparatus includes a printed circuit board in which at least one radar antenna pattern unit is mounted on a first surface thereof, a case, a cover, and a connector receiving portion. In a situation that a first connector is mounted on the printed circuit board such that a first terminal forms a first angle with respect to a first surface of the printed circuit board, the connector receiving portion receives the first connector to be exposed from the case. In a situation that a second connector is mounted on the printed circuit board such that a second terminal forms a second angle with respect to the first surface of the printed circuit board, the connector receiving portion receives the second connector to be exposed from the case.
