Abstract:
The lead of a T03 style transistor extends through a hole in a printed circuit board. A resilient connector is provided for connecting the transistor lead to a printed circuit conductor in a manner to allow dip soldering but avoiding stress on the lead which might break the glass seal on the transistor package. The connector is a spring clip having a U-shaped portion with a pair of aligned holes in the legs to grip the transistor lead, one of the legs extending into another U-shaped portion which resiliently engages the circuit board conductor when assembled to the transistor lead. The connections are secured by dip soldering to complete the assembly.
Abstract:
A driving mechanism for moving a flat optical element is provided. The driving mechanism includes a fixed part, a movable member, and a driving assembly. The movable member is movably disposed on the fixed part and connected to the optical element. The driving assembly is configured to impel the movable member and the optical element to move relative to the fixed part. The driving assembly has a coil disposed on the fixed part.
Abstract:
A contact component adapted to be soldered onto a metal region provided on an insulating substrate of a semiconductor module includes a cylindrical portion; a hollow hole for fitting an external terminal; and a flange formed at a lower end portion of the cylindrical portion and having a diameter larger than an external diameter of the cylindrical portion. An end face of the flange adapted to be soldered includes a flat bottom surface and a concave portion extending from an inner circumference edge of the cylindrical portion in the flat bottom surface to an outer circumference edge of the flange. The cylindrical portion includes a cut-out portion at an inner side of a lower end thereof.
Abstract:
An SMT LED device includes an LED and a circuit board carrying the LED. The circuit board has two copper pads thereon, each being provided with a solder on an inner later side thereof which faces the other copper pad. The LED includes two pins and each pin includes a horizontal protrusion and a vertical portion. The LED is mounted on the circuit board between the two copper pads. The solders securely and electrically connect the two pins of the LED with the circuit board.
Abstract:
A device, apparatus and printed circuit board assembly for removably coupling an electrical component with a PCB are described, which provides adequate electromechanical capability, is relatively insensitive to related heating, component removability, replacability and reworkability while minimizing wear and the possibility of resizing and damage. The device includes a sleeve for coupling with a component pin, which encloses the pin and further couples to a conductive barrel interconnecting multiple PCB layers. The sleeve conforms upon insertion within the barrel to its contour. A flange at an end of the sleeve deters over-insertion. The coupling so formed can be gas-tight.
Abstract:
In one aspect, a surface mount contact is provided for attachment to a circuit board or the like. The contact includes an elongated electrically conductive pin that has a first end and an opposing second end. A pre-formed heat re-flowable material is attached to one end of the pin and a conductive locator member surrounds the pin at a location between the first and second ends thereof and adjacent the conductive locator member. In one embodiment, the locator member is in the form of a cylindrical collar that extends around the pin.
Abstract:
According to the invention, a metal insertion piece (6) is provided in a solderable electrical connection element (1) with a thin support sheet (2), at least one metal conductor (3) and at least one free contact face (5), which may be joined to an associated connection face (11) of another component (12), by means of a soldered joint that can be made using a solder deposit (9), which metal insertion piece (6) passes through the connection element (1) and the support sheet (2) respectively in the region of the contact face (5) and is securely joined to this support sheet, which serves as a base for the solder deposit (9). Preferably, the insertion pieces (6) may be derived from conventional crimp attachments. They may also be used for mechanically fastening both the solder deposit (9) and an electrical conductor to the support sheet (2).
