Title:
POWER SUPPLY CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2022/034925
Kind Code:
A1
Abstract:
The purpose of the present invention is to develop a fast-rechargeable power supply connector. The present invention provides a connector having a contact structure that allows a large current to flow therethrough. In a contact-type power supply connector according to the present invention, a conductive layer 6 having a viscoelasticity is fixed between a rigid electrode 2 on the power-receiving side and a rigid electrode 1 on the power-transmitting side. At the time of power transmission, the two electrodes are pressed against the conductive layer 6 to deform the conductive layer 6, thereby increasing a contact area to obtain a low-contact resistance. In addition, a low-melting metal is disposed on the rigid electrode 2 and a surface of the conductive layer 6 having a viscoelasticity, and the low-melting metal is melted at the time of high-power transmission, thereby further increasing the contact area to achieve the low-contact resistance. In this manner, the connector exhibiting a small heat generation amount even during the high-power transmission is obtained.
