  • Patent number: 8127974
    Abstract: The new invention is a portable tool, specifically directed electric motor driven nail gun. It has a nail push system, also a motor. The motor uses a flywheel as a speed reduction mechanism, the main characteristic is that the drive unit of the driving mechanism is connected to a pitman by a pin axis on one end, and the other end is connected to the pin axis which does the arc movement. The end of the drive unit props up the long slot by a spring and enclosed by the long slot in a sliding movement. The rectilinear reciprocating drive unit is governed by a clutching mechanism mounted on the speed reduction mechanism. The new invention can provide a powerful impacting force. The clutch bar of the driving mechanism has an outer bulge and inner bulge, it controls the tension spring which makes the drive unit impact nails and recover after impacting nails, without any memory of the rotating state.

  • Patent number: 8118625
    Abstract: An electrical connector includes a row of terminals and a plastic base having a row of terminal slots. The terminals are disposed in the slots. Each terminal has an elastically moveable portion having a connection point, a fixing portion fixed into the slot, and a pin portion extending out of the plastic base. An inserted electrical element may be connected to the connection point and elastically move the elastically moveable portion. The row of terminals is one of two rows of terminals formed by oppositely tearing and pressing a metal sheet. The terminals have oppositely torn and cut portions seamlessly oppositely connected together. When the row of terminals is developed into a plane and one of the terminals is reverse-backside joined between the two neighboring terminals, the oppositely torn and cut portion of the terminal is seamlessly jointed to the oppositely torn and cut portions of the two neighboring terminals.
