The 5861 Series are space-saving Board to Board Connectors featuring a fine pitch of 0.35mm, stacking height of 0.6mm (between boards) and a width of 1.95mm. With the metals covering both ends, the connector, with narrow pitches and low profile though, realizes the structurally high robustness and smooth guiding function for mating to prevent breakage of the insulator housing and contact caused by misaligned mating. The metals at both ends of which rated current is 5A/metal tab enable to carry a large current.

Development Background

Electronic devices such as smartphones, wearable devices, and tablet PCs, are becoming multifunctional, and number of components are increasing. In order to effectively use the limited board space, miniaturization, thinness, and high-densit design are required.
While the mounting components are thinner and smaller, resulting in even more space saving, we have developed a connector that achieves high robustness and smooth mating guide function that facilitates assembly work.

Features

High Robustness and Smooth Mating Guide Structure

Metals covering the top surface prevent a decrease in strength which occurs from a finer pitch and lower profile, as well as damage caused by misalignments. The flat structure of the top surface covered with the metals guides the connectors smoothly for easy mating.

Space-Saving

0.35 mm pitch, space-saving connector suitable for high-density board design; stacking height: 0.6mm, width: 1.95mm, length: signal area+2.7mm.

Maximum Current of 5A is Applicable to the Metal Covers

By utilizing the metal covers on both ends as power sources, further space saving is possible by reducing the pin count. It also functions as a fixing metal to strengthen the peeling strength.

High Contact Reliability

Kyocera's unique pinching structure (two-point contact design), which is highly resistant to vibration and drop shocks, has been adopted for the contact structure. Furthermore, the plug contacts have an original structure featuring a wiping effect which eliminates foreign matter with concentrated load, thus realizing high contact reliability.

The red circle in the figure indicates the pinched two-point contact.
