Abstract: This invention is a connecting device for wireless communication. The said connecting device is primarily installed in a mobile phone to enable transmission and reception of message between both sides for communicating, in which the said connecting device utilizes the connecting technology of the Bluetooth or the public channel to enable end-to-end connection or multipoint connection, and thereby to enable transmission and reception of message. It also allows allocating an independent base station on a car or at a fix location for receiving and transferring message to relax the distance constraint of wireless communication and to support the function of hands-free.

Abstract: A modified structure for an electrical connector assembly provides connection between electronics, such as mobiles, notebooks, digital cameras, personal digital assistants (PDAs), wherein the electrical connector assembly includes a female connector assembly for insertion and connection, and a mating connector. By interlocking said female connector and mating connector and further in connection with the independent power supply, data and power supply are integrated in the structure design of the electrical connector. This prevents data loss, computer breakdown or interruption of power supply while transmitting data caused by loosening of connection between the mating connector and the female connector assembly.

Abstract: A ground elastic strap for a compact flash card housing, for serving as a ground elastic strap of a connector inserted by a compact flash card, or inserted into a host housing, includes corresponding left and right elastic protruding pieces, so as to come into contact with a metal housing of a compact flash card when the compact flash card is inserted. The ground elastic strap is able to function as a ground structure for ground connection of the compact flash card, and to further prevent electro static discharge (ESD), thereby increasing stability of the compact flash card when transmitting data with a host connected.

Abstract: A retaining terminal structure of a connector is for serving as a retaining terminal that provides retaining and positioning effects when assembling a connector. The retaining terminal as a formed integral by metal extrusion includes an L-shaped corner portion; a butting portion formed at a top portion thereof and for serving as butting ground guidance with a connected connector, so as to prevent electrostatic discharge (ESD); and a retaining portion formed at a side thereof and for serving as a retaining member when the retaining terminal is corresponded and assembled. Using the integrated structure of the retaining terminal having ground guidance, and retaining and positioning effects, a number of terminals and retaining components at an interior of the connector is reduced, thereby decreasing steps and production expenses needed for assembly of the connector.

Abstract: The present invention relates to an electric signal plug with status display, including a plug that connects to an electric cable at one end for linking to the electric signal source; the above-described plug can detect and display electric signal strength by connecting a circuit detector equipped with an IC detector and at least one display component to the electric cable, moreover the formation of a display ring from the internal tube and outer case directly reveal to the outside the strength of the electric signal inside the electric cable.

Abstract: An improved structure universal serial bus (USB) connector female socket in which a grounding ring is disposed at the lower edge of a metal housing enclosing the connector terminals, with the two sides of the metal housing covered by an insulative integument to form the USB connector female socket. The grounding ring can be fastened by a screw and, furthermore, the metal construction of the grounding ring strengthens signal transmission, while also providing for grounding capability, thereby enabling the present invention to strengthen bidirectional signal transmission as well as effectively prevent the occurrence of electrostatic discharge (ESD) during computer peripheral (such as scanners, digital cameras, and keyboards, etc.) operation.
