Abstract: A surface mount coaxial cable connector comprising a generally elongate block. A channel extends between the proximate and remote ends for receiving a coaxial cable and includes an upstream larger diameter channel and a downstream, smaller diameter channel for receiving with little clearance the central conductor after the shield and the outer layer have been removed. The lower surface of the block is provided with slots extending from the lower surface to the stepped channel. One slot is arranged along said central plane and aligned with the central conductor within the smaller diameter channel and two slots are offset from the central plane. A plurality of piercing blade contacts within the slot extend beyond said lower surface that have extended piercing contact portions with opposing free edges suitable for surface mounting on a printed circuit board.

Abstract: There is provided an insulation displacement connector (IDC) assembly having a main body defining at least one wire channel. The main body has at least one substantially flat surface to which a vacuum nozzle can be affixed in order to pickup the IDC assembly. The IDC assembly has at least one contact member with a piercing, cutting or slicing end that is slideably disposed within the main body, and a mounting end that extends from the main body. The mounting end of the contact is attached to a printed circuit board. An insulated conductor, such as wire, cable, and/or ribbon, can be quickly and easily inserted in the channel without being pierced by the piercing end of the contact. When a user pushes down on the IDC, the contact slides into the channel and pierces the insulated conductor.

Abstract: There is provided electrical contact for circuit boards. Each leg of the pin section has a deformable segment that can expand or contract along the direction of the leg to alleviate stress created by relative movement of printed circuit boards and/or off-board components interconnected thereby. The deformable segments have members that project in opposing directions relative to the direction of the leg, so that the segments are symmetrical. In one embodiment, each leg has a deformable segment having a outwardly curved shape. In another embodiment, each leg has a deformable segment in the shape of a rectangular frame. The deformable segments define at least one opening where the two legs of the pin section are not overlapping, which breaks the capillary flow of solder between the legs. The amount of solder that flows into the electrical contact is selectively controlled by the selected placement of the deformable segments.

Abstract: A capillary action enhanced surface mount pin header includes a first flat substrate provided with a predetermined array of plated-through holes having substantially parallel and each having an internal surface defining a first substantially uniform cross section. Pins are provided each of which defines a longitudinal axis and having one end extending through an associated plated-through hole and another end extending to one side of said first substrate. Each pin has an external surface on at least a portion thereof which is received within an associated plated-through hole which defines a second substantially uniform cross section. In the disclosed embodiment, the pins have square or hexagonal cross sections while the plated-through holes have circular cross sections.

Abstract: One and two piece surface mount pin constructions include excess solder receiving channels. In the one piece construction an elongate channel is provided through a tubular pin which is flared or swaged at the lower end to form a base. In the two piece construction a solid pin is provided at a lower end with a uniform cross section in the form of a regular polygon, such as a square, hexagon or octagon. The resulting edges are press-fit against an internal surface of a sleeve which is also swaged at a lower end to form a base. The spaces between the sleeve and the flat or convex surfaces on the captured end of the pin provide the solder-receiving channels. A bead or shoulder on the pins can provide a stop for a vacuum nozzle. When a flared upper lip is used for this purpose it can also serve as a reservoir or well to receive excess solder beyond the amount that can be received in the channels.

Abstract: A box contact is disclosed which is coated on the interior surface thereof proximate to the lower open end as well as on the upper ends of the mounting legs with a solder-resistant tape to prevent solder from wicking into and blocking the lower open end of the contact portion. The method of producing such anti-wicking box contacts is also described.
