Open Bottom Low-Profile Socket Contacts

Preci-Dip's screw-machined contacts using multi-finger clips are a robust solution for harsh environments, with the main advantage being customization. The sleeve can be easily customized to fit specific user requirements, while the clip remains a standard, proven part.

Preci-Dip has developed a specific series of screw-machined contacts known as open bottom contacts. One of the main advantages of open bottom contacts is their independence from pin length. Since there is no bottom to the contact, there are no restrictions on the pin length. The pin can significantly extend beyond the other side of the contact. This design avoids the need for excessively long contacts to accommodate variations in pin length and reduces costs.

Incorporating a wide guiding chamfer is highly appreciated when designing open bottom contacts. This chamfer serves two purposes: first, it facilitates insertion in blind mating configurations; second, it allows for easy relocation of the pin’s localization.

Open bottom contact design is ideal for stackable configurations. In this setup, the pin can pass through multiple contacts in a row, allowing for the connection of several boards together.

Another advantage of the open bottom contact design is its suitability for low-profile solutions, including 0-profile configurations. Minimizing the shoulder required for soldering the contact onto a board allows space-efficient assembly.

Applications

• Automotive: The open bottom contact proves to be a robust solution. It can accommodate standard square pins from various devices, including blowers or windshield wiper motors
• Industrial: The open bottom contact can serve as a wire trap, allowing for easy wire-to-board connections, especially in blind mating scenarios
• Consumer electronics: Open bottom contacts serve as an excellent solution for making PCB components pluggable, removable, and replaceable. Their design allows for easy insertion, removal, and replacement of components, enhancing flexibility and maintenance efficiency
