  • Publication number: 20120058686
    Abstract: An electrical connector includes an insulative housing having a base portion defining a receiving cavity therein and a mating portion unitarily formed with the base portion and protruding outwardly from a front face of the base portion so as to define an insertion opening in communication with the receiving cavity. A plurality of terminals are received in the receiving cavity, each of which has a contacting portion extending rearwardly and upwardly from a position adjacent to the insertion opening. A rear cover is assembled on a rear section of the base portion and severs as a rear wall of the base portion. The insulative housing is formed by a double-colored-injection method and the mating portion and the base portion are configured as different colors. The double-colored-injection method can save an assembling process for the electrical connector, which is helpful for reducing the manufacturing cost.

  • Publication number: 20110116861
    Abstract: The present application provides a battery pack locking device, comprising a button, a snap element for engaging the battery pack with an electrical appliance, a linkage controlled by the button, a spring provided below the button and a support. The snap element is hinged to the support at one end and the first end of the linkage is disposed below the button. When the button is pressed down, the first end moves down and the second end of the linkage moves upwardly relative to the first end. Also, the snap connecting portion moves downwardly in a curved path without squeezing the snap groove of the electrical appliance, resulting in decreased friction between the parts and a reduced force necessary to press down the button. Accordingly, the battery pack can be easily mounted to and removed from an electrical appliance.

  • Publication number: 20080035361
    Abstract: The present invention provides an electric handheld power tool, which comprises a tool housing, a motor mounted within the tool housing, a fan, and an output mechanism driven by the motor; a cover of the motor has an air inlet and an air outlet, and the motor housing has at least two slots which are angularly offset with respect to the air outlet, and at least one rib extending outwardly from the motor cover. Since the slots of the housing are offset with respect to the air outlet of the motor cover in an angular direction, electric sparks that may be generated in the motor are substantially isolated and constrained by the housing and not allowed to flow to outside of the housing. Therefore, potential danger is avoided and operational safety is enhanced. At the same time, the cavity between the motor cover and the tool housing is divided by the rib such that circulation of the air in the space is prevented.
