Abstract:
A rotatable light-emitting diode (LED) arrangement includes a LED member, a retaining housing for retaining the LED therein and a positioning base for positioning the rotatable housing to a panel of an electronic/electrical device, such as a back panel of a computer enclosure. The retaining housing includes a ball-like retaining portion defining a chamber for retaining the LED therein, and a cylindrical portion connecting with the ball-like retaining portion for receiving leads of the LED therein. The positioning base defines an unclosed spherical opening therein for rotatably receiving the ball-like retaining portion of the retaining housing and a pair of curved annular recesses respectively connecting with opposite open ends of the cylindrical opening for allowing proper rotations of the ball-like retaining portion of the retaining housing therein. Thus, the LED member of the LED arrangement can emit infrared lights in different directions simply by properly rotating the ball-like retaining portion of the retaining housing, whereby a detector can easily detect the infrared emitted by the LED without being previously positioned.
Abstract:
A PEMF therapy system uses a single-coil PEMF transducer for generating PEMF stimulation signals. The coil has a “bi-phasic” operation, such that current flows through it in two directions A drive circuit recovers the flyback energy from the transducer coil and dumps voltage to an energy recovery capacitance circuit. The transducer is thereby energized and de-energized to provide the electromagnetic field. The single coil transducer may be fabricated on a flexible substrate and the wiring may be formed with printed circuit techniques. The same concepts may be applied to series-connected coils.
Abstract:
A latch mechanism for firmly engaging a first connector and a second connector includes a fixing plate with a linking portion perpendicularly extending therefrom, a pair of extending portions perpendicular to the fixing plate, and a locking portion downwardly extending from the linking portion. Grasp arms downwardly extend from ends of the extending portions for engaging the first connector. The locking portion is firmly inserted into the first connector to form a reliable connection therewith. The fixing plate is securely retained in the second connector whereby the first and second connectors are firmly engaged.
Abstract:
A locking device for securing first and second electrical connectors together comprises a first member and a second member. The first member comprises a mounting post received in the first connector and a spherical head extending beyond the first connector. The second member comprises a retention portion secured in the second connector and a spring arm having an engaging portion. The engaging portion is semi-bowl shaped to adapt for engaging with the head. When the first and second connectors are mated together, the head engages the engaging portion with at least a rear portion thereof abutting against a free edge of the engaging portion thereby establishing reliable engagement between the head and the engaging portion.
Abstract:
A cable connector assembly which reduces a cross sectional area of an end portion of a cable and which can be conveniently and securely assembled to a connector, comprises a main body, a cable and a clamp device. The main body has a connecting portion receiving a number of terminals for electrically connecting with a mating connector at one end and a receiving space accommodating a housing block. The cable has an electrical portion at an end portion thereof for electrically connecting with the terminals of the connecting portion. The clamp device comprising at least two clamping portions and fixing portions corresponding to the housing block is received in the receiving space and assembled to the housing block. Thus the end portion of the cable is deformed and retained by the clamping portions and secured to the housing block by the fixing portions of the clamp device.
Abstract:
A cable assembly connector includes a housing, a shell unit and a cover unit. The housing has a circuit plate for receiving terminals of a cable, a mating frame, and a pair of supporting portions formed on opposite lateral sides thereof. The cover unit has a first and second covers. A plurality of projections is formed on inner surfaces of the first and second covers proximate an engaging port. A pair of grounding plates respectively extends perpendicularly from an edge of the first and second cover proximate a receiving space thereof. A plurality of protrusions is formed on the grounding plate for electrically contacting a metal shell of a mating connector and for grounding static electricity accumulated thereon.
Abstract:
A cable end connector comprises a metal shell and an insulative housing. A pair of locking elements is formed at lateral sides of the housing. A mating slot is formed in the mating side of the housing. A projection extends from the housing into the mating slot. A plurality of receiving slots is formed in the projection of the housing for receiving a plurality of terminals therein. A pair of locking holes is formed at lateral sides of the metal shell for engaging with the corresponding locking elements. A pair of grounding plates is soldered at lateral sides of the metal shell. Each grounding plate has a solder portion and a contacting portion, the solder portion being soldered to the metal shell, the contacting portion providing electrical contact with a metal panel. An opening is formed between the solder portion and the contacting portion for enhancing the resilience of the grounding plate.
Abstract:
An electrical connector comprises a body, a metal plate and a shield. The body defines a plurality of passageways for retaining terminals therein. The shield encloses the body and the body has an exposed bottom face for mating with a circuit board. The metal plate surrounds the body, and a pair of board locks is formed on opposite lateral ends of the metal plate. Each board lock comprises a base, a pair of folded portions extending from opposite ends of the base, a leg extending from each folded portion, and a barb formed on a free end of each leg. A resilient plate extends from a central portion of the base. A folded tip is formed on a free end of the resilient plate. When the board lock extends through a receiving hole of another circuit board having a different thickness, the electrical connector is properly secured to the circuit board due to the provision of the resilient plate and the barbs.
Abstract:
An electrical connector (100), comprising an insulative housing (1) defining a base portion (11) and a mating portion (12) extending from the front side of the base portion along a mating direction; a plurality of passageways (114) disposed in the base portion with an opening backwards and extending along the mating direction; a plurality of receiving spaces (121) disposed in the mating portion and communicating with the complementary passageways; a plurality of contacts (2) mounting to the insulative housing along the mating direction, and each contact including a flat base part (21) mounting to the base portion of the insulative housing, a connecting part (22) extending forwards from the base portion and received in the passageways, a mating part (23) extending from the connecting part and disposed in said receiving space, and a spacer part (24) located between the base part and the connecting part; wherein the spacer part covers the opening of the passageways.
