Patent number: 6325682Abstract: An electrical lead includes a substrate-receiving section which has a collapsible rear plate and a plurality of outwardly projecting prongs or arms. The prongs are spaced apart to define a gap having an opening slightly larger than the width of the substrate to be engaged. A substrate is inserted into the gap between the prongs so that the prongs are spaced on either side of the substrate. The rear plate of the lead is then compressed so that the prongs engage and tightly grip the substrate from opposite sides. Alternatively, the prongs may pivot upon the application of force to engage the substrate.Type: GrantFiled: December 10, 1999Date of Patent: December 4, 2001Assignee: North American Specialties CorporationInventor: Jack Seidler

Patent number: 5967833Abstract: A circuit board connector (10), such as for a flex circuit (20), which provides a solid and reliable contact termination between a flex circuit (20) and a connector. The flex circuit connector (10) includes multiple contact points (24, 26) for contacting each lead or trace on the flex circuit (20). The multiple contact points (24, 26) are provided along a common member (28) which also includes a strain relief mechanism (30) in between the multiple contact points (24, 26). The strain relief mechanism (30) may be provided in the form of a V-shaped bend in the material of the common member (28) connecting the multiple contact points (24, 26) together. The contact points (24, 26) used to join the flex circuit (20) and the connector (10) may be achieved using any combination of staple-like contact points or solder contact points. The addition of the strain relief mechanism (30) in between the contact points (24, 26) greatly enhances the termination between the flex circuit (20) and the connector (10).Type: GrantFiled: August 6, 1997Date of Patent: October 19, 1999Assignee: North American Specialties CorporationInventor: Joseph S.

Patent number: 5908323Abstract: A zero-insertion force connector having a frame which includes a selectively deformable base. Contacts are supported by the base and are selectively displaced from an insertion path when the base is deformed, allowing insert elements, such as wire from flat cable, or a printed circuit board, to be inserted between the contacts without substantial resistance. Releasing the force which is deforming the base allows the base to return to its rest shape under a natural resiliency of the material used to make the base, which causes the contacts to move against the inserted element and establish electrical communication.Type: GrantFiled: February 26, 1997Date of Patent: June 1, 1999Assignee: North American Specialties CorporationInventor: Jack Seidler

Patent number: 5653617Abstract: A connector for substrates such as smart cards has a housing containing two parallel rows of spring contacts, each of which is held in a respective channel of the housing. Integral with each of the spring contacts and extending outside of one end of the housing is a terminal lead for connection to a substrate. The lead has a solder mass adjacent its end. The two parallel rows of solder-bearing leads will straddle and resiliently hold a substrate between them to improve accuracy in soldering during solder re-flow. The other end of the housing is provided with entry apertures for pins of a multi-pin connector, so that each pin will enter a respective housing channel to contact the spring contact therein. The entry apertures may accommodate a substrate with contact pads.Type: GrantFiled: June 28, 1995Date of Patent: August 5, 1997Assignee: North American Specialties CorporationInventor: Jack Seidler

Patent number: 5571034Abstract: A method of making an array of electrical components having pre-attached leads ready for automated surface-mounting on a substrate. The method involves aligning an array of leads with electrical components and attaching each lead to a conductive terminal on a respective component. A series or coil of leads joined integrally together and carried by a carrier strip is thus provided with a series of electrical components pre-attached thereto. The electrical components along with their leads may thus be quickly and easily surface-connected to the conductive pads on a substrate in a simple, automated manner.Type: GrantFiled: January 20, 1995Date of Patent: November 5, 1996Assignee: North American Specialties CorporationInventor: Jack Seidler

Patent number: 5246391Abstract: A solder-bearing lead having a C-clip to resiliently grip the upper and lower surfaces of a substrate. One of the two arms forming the "C" is solder-bearing for mechanical and electrical connection to a conductive area on the substrate. In one embodiment, a polymer plug may be provided on the second arm, the plug having a narrowed neck region for improved retention by the second arm. In another embodiment, the second arm is coated with a non-conductive material, eliminating the need for mechanically retaining a plug or other insulator between the second arm and substrate.

Patent number: RE35549Abstract: A solderable lead is fashioned with a C-shaped contact portion along its length. The interior of the C-portion is dimensioned to receive and resiliently contact a substrate at a predetermined contact pad. A layer of solder is provided on the exterior of the C-shaped contact portion and extends around its edge. During heating, the solder migrates to the interior of the C-portion by capillary action to the area between the contact pad of the substrate and the interior of the C-portion. While the solder is liquid, the C-portion maintains engagement with the substrate.Type: GrantFiled: October 12, 1993Date of Patent: July 1, 1997Assignee: North American Specialties CorporationInventor: Jack Seidler
