Abstract: A joint assembly of vapor chambers connects the vapor chambers to effectuate joint operation thereof. For example, two paired vapor chambers are connected therebetween by a capillary pipe and a gas pipe. The capillary pipe is filled with a third wick which connects with a first wick and a second wick in the two vapor chambers. The two vapor chambers are in spatial communication with each other because of the gas pipe. A working fluid in the two vapor chambers is transferred between the first, second and third wicks by capillarity. The gas-phase working fluid moves between the two vapor chambers via the gas pipe, thereby allowing the two vapor chambers to operate jointly.

Abstract: A card connector composed of a base frame, at least one terminal set, and a detective terminal. While a card enters a card space inside of the base frame, it works on and forces a working portion of a working springy piece of the detective terminal toward a passive springy piece of the detective terminal for electric conduction with the same. When the working springy piece is moved to contact the passive springy piece, a scraping portion of the working springy piece contacts and scraps a contact portion of the passive springy piece to force the passive springy piece to deform; meanwhile, the resilience generated by the deformation of the passive springy piece keeps it in contact with the working springy piece. In this way, during the contact, the oxide or stain can be scraped off f to make the contact more perfect to secure the detective accuracy.

In light of the structure, the airflow guider can be coordinately installed to various kinds of heat sinks and provide additional thermal dissipation.
