As industrial equipment continues to become more compact and integrated, internal space within devices is increasingly constrained. The available room on circuit boards for components is becoming smaller. In many cases, RF connectors—being relatively larger than other electronic components and requiring mating with external interfaces—often become the bottleneck in space-constrained designs. In previous articles, we mentioned using board-mounted RF connectors, but these are often unsuitable for scenarios such as through-panel structures or radial connections. For such cases, we have another option: angled RF connectors.
Features and Applicable Scenarios of Angled RF Connectors
Advantages:
- High Mechanical Strength:
Through-panel design integrates the PCB with the metal parts of the connector, forming a unified structure that resists pulling and vibration more effectively. - Compact Space Usage:
The angled structure reduces the overall vertical height of the connector, minimizing the distance between boards or between the board and enclosure, enabling a more compact internal layout. - Convenient Mating:
The angled design allows more flexibility and ease during mating with other connectors.
Disadvantages:
- Higher Design Complexity:
Unlike traditional connectors, the angled cavity alters signal path directions, increasing the design difficulty. - Higher Cost:
The housing and internal components require more complex machining processes compared to traditional connectors, resulting in higher manufacturing costs.
It is evident that angled connectors can significantly reduce space requirements, making them an ideal solution in today’s trend toward miniaturized devices. However, due to the angled cavity design, RF signal transmission can be affected. To maintain or even improve RF electrical performance compared to traditional connectors, higher standards in connector R&D and design are required. The Johnson product line under Cinch has, after years of research and practical experience, successfully developed a series of high-performance angled RF connectors.
