Abstract: An antenna has a plurality of metallic patches and a feed network both being spaced apart from a ground plate at different levels to obtain better radiation pattern and gain effects. Each of the metallic patches has a body with an outer edge from which an inclined wing extends upwardly and outwardly. Furthermore, the metallic patches and the feed network are integrally formed by bending a single piece of metal plate, thus the antenna improves the design flexibility and also simplifies the production process.

Abstract: A battery connector has an insulative housing, a plurality of contact terminals mounted in the insulative housing and a washer mounted on the insulative housing. The insulative housing has a first surface, a second surface, a third surface and a plurality of notches defined through the third surface. Each notch communicates with a first opening and a second opening respectively defined on the first surface and the second surface.

The at least one top elongated recess prevents the insulative housing from being defective and deforming when the insulative housing is manufactured by an injection molding process.

Abstract: A memory card connector has an insulative housing, a power switch and a plurality of conductive terminals. The power switch is mounted in the insulative housing, to detect a memory card and has a first detecting terminal and a second detecting terminal. The first and second detecting terminals are mounted in the insulative housing. The second detecting terminal selectively contacts the first detecting terminal to supply power to the memory card connector when the memory card is installed in the memory card connector. When the memory card is removed, the power switch cuts the power to the memory card connector to save power.

Abstract: A connector has an insulative housing, a plurality of terminals and a metal shell. Each terminal has a soldering section. The soldering sections of a power terminal and a grounding terminal are the outermost terminals and are located outside remaining terminals instead of being located respectively between the soldering sections of signal transmitting or receiving terminals. The outermost soldering sections of the power and grounding terminals prevent the interference with the signal transmitting and receiving terminals during signal transmission.

Abstract: An integrated broadband antenna device with wide band function is disclosed. The antenna device comprises a ground plate, a feeding wire, a first metal radiator, a second metal radiator, a ground metal radiator and a parasitic metal radiator. The first metal radiator is connected with the positive ends of signals of the feeding wire for transmitting electric signals and producing a high frequency mode. The first metal radiator is coupled to and energizes the second metal radiator and the parasitic metal radiator, and then the two metal radiator producing a low frequency mode and a second high frequency mode along with the ground metal radiator obtains a wider bandwidth. The broadband antenna device integrating various kinds of antennas is able to have a enough bandwidth to meet the requirements of AMPS (824˜894 MHz), GSM (880˜960 MHz), GPS (1575 MHz), DCS (1710˜1880 MHz), PCS (1850˜1990 MHz), UMTS (1920˜2170 MHz) and Wi-Fi (2400˜2500 MHz).

Abstract: A micro plug connector has an insulative housing, a plurality of terminals, a pair of positioning hooks and a metal shell. The insulative housing has a base and a tongue protruding from the base. The terminals and positioning hooks are mounted through the base into the tongue.

The terminals are mounted respectively in the mounting slots and respectively hold the probe contacts and each terminal has a fastening portion. The fastening portion is perpendicularly to and securely holds one probe contact. The terminal with the fastening portion is mounted perpendicularly on the probe contact instead of sliding longitudinally along the tubular body. Therefore, the terminal would not wear the probe contact.

The coupling conductor has a first coupling member and a second coupling member being separated from each other. The conductor string and the ground conductor are connected to the second coupling member. The conductor string extends along a direction opposite to the second coupling member. The ground conductor is connected to the ground plane. The broadband antenna uses the coupling conductor and the ground conductor to adjust input impedance for impedance match. The conductor string functions as a multi level resonance circuit to increase impedance bandwidth.
