Abstract: An electrical connector includes a front shielding shell member, a front housing member, a number of contacts, a rear housing member and a rear shielding shell member. The contacts are mounted to two sides of the rear housing member to prevent the contacts from moving sideward and to and fro. The rear housing member with the contacts is then inserted into a cavity defined in the front housing member to fixedly connect therewith, whereby contact portions of the contacts extend into contact passageways defined in the front housing member and are further prevented from moving upward and downward, whereby the contacts and the front and rear housing members are all fixedly connected. Finally, the front shielding shell member is mounted to the front housing member and the rear shielding shell member is connected to the front shielding shell member to accomplish the assembly of the electrical connector.

Abstract: An electrical jack comprises a rectangular insulative body, an insulative bottom member, a grounding terminal, two signal terminals, and two detecting terminals. The signal terminals and the detecting terminals are received in passageways defined in the body. The signal terminals each have a fixing portion a spring portion, an engaging portion and a solder portion proximate the engaging portion. The spring portion is deflected by a pin of an inserted connector to engage with the engaging portion thereby providing a short electrical path therethrough.

Abstract: A plug connector unit includes at least two identical insulative housings each of which retains two rows of contacts in a central wall thereof, wherein a portion of the contacts are defined as ground contacts while the remaining contacts are non-ground contacts, wherein the ground contacts are longer than the non-ground contacts and located at least at distal ends of each row in the central wall of the housing. A metal shielding is used to link the insulative housings as a unit.

Abstract: A USB receptacle connector includes a dielectric housing having a rear wall and an inner space. A plate extends from the rear wall through the inner space to an outside of the housing. The plate defines a number of horizontal contact passageways. The rear wall defines a number of vertical contact passageways in communication with the horizontal contact passageways. Two slots are defined from two lateral sides of the rear wall to the inner space of the housing. A number of contacts having contact portions and tail portions are interferentially received in the corresponding horizontal and vertical contact passageways. A front metal shielding has a rear part received in the inner space of the housing, and two side walls having rear portions extending into the slots to fixedly engage with the housing. The front shielding member covers the contact portions of the contacts.

Abstract: An electrical receptacle connector includes a dielectric housing having a body portion receiving a number of contacts therein and two ears each defining a central hole with a hexagonal upper section and a round lower section and two elongate slits. A shielding/grounding shell is formed with a body portion covering the body portion of the housing, and two wings each formed with four mounting tongues fittingly positioned on four mounting seats defined in the hexagonal upper section of the hole of the corresponding ear and two grounding feet extending through the corresponding slits. Two conductive posts are each formed with a domed upper section located above the body portion of the shielding/grounding shell, a middle hexagonal section positioned on the corresponding tongues of the shielding/grounding shell, and a lower cylindrical section received in the corresponding round lower section of the corresponding hole and defining a threaded portion therein.

Abstract: A locking mechanism for attaching a connector to a PCB having a mounting hole comprises a lock body including an attaching portion for fixedly attaching to the connector. A first and second resilient retaining legs extend from for inserting into the mounting hole of the PCB. A first space is defined between the first and second resilient retaining legs. A deformation facilitating means is arranged on the lock body adjacent to the resilient retaining legs whereby the deformation of the resilient retaining legs can be homogeneously and efficiently transformed to the lock body.

Abstract: An electrical connector includes a unitary insulative housing having an upper half and a lower half respectively defining a first chamber and a second chamber therein. A plurality of first conductive pins are received in the first chamber and enclosed by a first shielding member to form a power connector for transmitting electrical power. A plurality of second conductive pins are received in the second chamber and enclosed by a second shielding member to form a signal connector for transmitting signals. The signal connector may be a USB (universal series bus) connector. Thus, the USB connector has an integral power connector for supplying electrical power to drive electronic devices connected thereto.

Abstract: An ejecting mechanism for use with a card cartridge connector comprises a casing integrally formed with the card cartridge connector. A push rod is movably disposed within the casing, a biasing tab is movably disposed within the housing. The biasing tab forms a mating face engaged with an actuating end of the push rod, and an ejecting face extending into a receiving slot defined within the card cartridge connector. Therefore, when the push rod is actuated, a card inserted within the receiving slot is ejected.

Abstract: A board lock includes a fixed section adapted to be fixed to a connector and a pair of spaced legs connected to the fixed section by means of a resilient section. The legs lie in a plane which is substantially normal to the fixed section and are arranged on opposite sides of the fixed section. The legs form convex portions arranged on opposite sides of the plane thereof for engaging with an edge of a hole of a circuit board into which the legs are inserted thereby securely and stably retaining the connector on the circuit board.

Abstract: A connecting terminal for use with a battery connector comprises a retaining section for attaching to a substrate. A first curved portion extends from the retaining section at a free end thereof. A first supporting portion extends from the first curved portion at a free end thereof. A second curved portion is formed at a free end of the first supporting portion, and a second supporting portion extends from the second curved portion. The second supporting portion forms a biasing end at an end thereof, and at least a reinforced rib is formed on one of the first and second curved portions thereby increasing the modulus of elasticity of the first curved portion.

Abstract: A boardlock for an electrical connector is disclosed. The boardlock comprises an attachment section for attaching to an electrical connector and an insertion section for inserting into a hole of a circuit board. The insertion section includes a leg plate and a spring piece laterally bulging from a lateral portion of the leg plate. The spring piece is a strip bending out of the leg plate in V shape from its middle portion with both ends of the spring piece connected to the leg plate. Also, a shielding device for an electrical connector comprising a pair of above-mentioned boardlocks integrally formed on it is disclosed.
