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 metal shell covers the insulative housing and has a front cover and a rear cover. The front cover is mounted around the tongue and has a connecting plate protruding from the front cover and partially covering the bottom of the base. The rear cover formed on the front cover and covers the base and the connecting plate of the front cover. The front and rear covers double cover the insulative housing to strengthen the structures of the micro plug connector and prevent inadvertent disassembly or failure of the micro plug connector.

A coupling antenna has a substrate, an inducting conductor, a ground plane, a first coupling member and a second coupling member. The inducting conductor is mounted on the substrate. The ground plane is formed on and protrudes from the inducting conductor and is mounted on the substrate. The first coupling member is mounted on the substrate and is connected to a feeding cable. The second coupling member is mounted on the substrate and is connected to the first coupling member. The coupling antenna with the first coupling member, the second coupling member and the inducting conductor has a wide bandwidth and a small size.

An antenna array unit is provided by the present invention. The antenna array unit includes: a ground, a feeder cable, a first signal feeding member, a plurality of second signal feeding members, a plurality of third signal feeding members, a plurality of first rectangular radiating members and a plurality of second rectangular radiating members. The first rectangular radiating members have first and second non-radiating sides, two radiating sides able to generate a coupling effect with a radiating side adjacent thereto. The second rectangular radiating members have first and second non-radiating sides, two radiating sides and able to generate a coupling effect with a radiating side adjacent thereto. The present invention is characterized in that at least one current disturbing member is formed at each non-radiating second side of the plurality of the first and the second rectangular radiating members and adjacent to the nearest radiating side generating the coupling effect.

An electrical connector includes a top plate, a first clamping plate extending integrally and downwardly from a first side of the top plate, and a second clamping plate extending integrally and downwardly from a second side of the top plate, and cooperating with the top plate and the first clamping plate to define a clamp for clamping a grounding plate. A connecting member extends integrally from the second side of the top plate and is connected electrically to a ground pattern provided on a circuit board of an antenna module.
Abstract:
A wide band antenna has a ground plane, a dielectric member and a radiating patch. The dielectric member is mounted on the ground plane. The radiating patch is held by the dielectric member, is mounted on the ground plane and has a main conductor, a feeding conductor, a coupling conductor, an extension conductor and a shorting conductor. The main conductor has a first resonant mode. The extension conductor has a second resonant mode. The coupling conductor is capable of feeding high frequency signals into the main conductor and the extension conductor by capacitive coupling effect. With the main conductor, the extension conductor and the coupling conductor, the size of the wide band antenna is effectively reduced.
Abstract:
A light-emitting device of a light-emitting diode (LED) and a manufacture method thereof are provided. The light-emitting device includes a post-like metal material, a printed circuit board, conductors, insulators, light-emitting diodes, wires, and an encapsulating material. The light-emitting device has through holes, in which conductors are disposed and surrounded with the insulators. One end of each conductor is connected to the printed circuit board to form a composite structure heat-dissipation substrate. The light-emitting diodes are disposed on the post-like metal material, connected to the conductors via the wires, and encapsulated by the encapsulating material. Furthermore, the light-emitting diodes, the wires, and the encapsulating material can be combined into a light-emitting unit. Moreover, red, blue, and green light-emitting diodes can be combined and the color of output light thereof can be adjusted by controlling the input signal.
Abstract:
An audio jack is embedded in an open mounting slot of a printed circuit board (PCB). The open mounting slot has two opposite inside surfaces. The audio jack has an insulative housing and two sets of terminals. The total thickness of the PCB with the audio jack embedded therein is less than a sum of the thicknesses of the PCB and the audio jack so that the PCB with the audio jack may be applied conveniently to compact electronic devices.
Abstract:
A card connector base is mounted on a printed circuit board and has a metal-inserted housing, a pair of hooking assemblies and a card tray. The metal-inserted housing has a metal substrate and an insulative body. The insulative body is mounted securely on the metal substrate by an insert-molding process. The hook assemblies are mounted on the metal-inserted housing. The card tray is detachably mounted slidably in the metal-inserted housing. Because the metal substrate formed from the sheet-metal is thin and has fine structure strength such as tensile strength and compressive strength, the metal-inserted housing with the metal substrate is more compact and more structurally strong when compare to conventional insulative housings.
