Abstract:
A multiconductor electrical cable termination (10) for flat ribbon cable (11) has plural electrical contacts (26) pierced through the cable inslulation to engagement with respective conductors (13). The junctions of contacts and conductors are encapsulated in a base (15) that forms an integral structure with the contacts and cable maintaining the junctions substantially free of oxygen and moisture. Plural openings in the base provide access to terminal portions of the contacts for test probing thereof, or the like, while the contacting portions (12) of the contacts (26) are connected to another termination, connector or the like. The cable termination assembly is formed using both an insulation displacement mass termination connection of the contacts (26) and cable conductors and additionally has a solder connection (42) provided between respective contacts and cable conductors, for example during or after such encapsulation.
Abstract:
A termination system comprising a receptacle (21) which includes a center pin contact (40) extending along an axial extent of the receptacle, an outer tubular shell contact (42) coaxially positioned with respect to the pin contact (40) and having an internal contact surface for electrically connecting with the external contact surface of a terminator sleeve contact (35), and a spacer (26) for maintaining electrical isolation and spaced relation of the pin and shell contacts for matching the impedance of the receptacle (21) to that of the terminator and cable (23). The carrier block (71) for a plurality of terminators is a conductive plate-like member having plural openings (78) for receiving and electrically engaging with the external contact surface of respective terminator sleeve contacts (35) thereby to couple the same to a common reference potential, such as ground reference potential, and is mountable and electrically connectable to a printed circuit board (73) by a port member (72).
Abstract:
An electrical contact (1) of the fork type has substantially parallel and coplanar tines (4, 5) and in the contacting or wiping area (17, 16) of each tine inlay material (14, 15) improves electrical connection thereof with a member inserted to engagement therewith. The noted inlay material, such as gold, palladium silver, or the like, preferably is applied only to the relatively limited area of each tine that maintains direct engagement with such inserted member. A twist (34) in each tine aligns the respective contact areas that contain such inlay material with each other in confronting relation for such wiping engagement. The contact, moreover, may be die cut or stamped, and the twist enables alignment of the respective smooth side surface of each tine in respectively confronting relation with each other, allocating the back of each tine, i.e. that portion not intended to engage such inserted member, for the burr side surface. An electrical connector, such as a cable termination or cable termination assembly, may include such contacts.
Abstract:
An electrical component (21) for mechanical mounting and electrical connection with respect to plated through holes of a printed circuit board compatibly with a surface mount attaching process includes an electrically non-conducting body (30), plural generally elongate contacts (31) extending from the body for insertion into such plated through holes, and the component (21) having a reservoir (31) for retaining solder type material (33) for melting, for flow into respective plated through holes, and for re-solidifying mechanically and electrically to couple the component to such printed circuit board. Preferably the component is a connector, such as a beader, and the contact pins or leads thereof provide an interface connection between the printed circuit board and a separate or portable connector. A method for attaching such an electrical component (21) to a printed circuit board compatibly with surface mount attaching processes, a method for placing solder (33) in the reservoirs (32) of such electrical components, and apparatus to carry out such methods.
Abstract:
Un procédé de fabrication d'un contact plan en forme de fourche (1) ayant au départ plusieurs dents (4, 5) avec des surfaces respectives co-planaires et un matériau incrusté d'or (20, 21) solidaire de ses surfaces co-planaires, consiste à tordre les dents pour tourner les surfaces co-planaires et les amener en relation de confrontation l'une par rapport à l'autre dans le plan du contact. D'autres étapes comprennent la mise en place de la torsion pour maintenir les zones de contact contenant l'incrustation en relation de confrontation, le contrôle de cette torsion et la position des torsions respectives pour assurer l'uniformité des contacts, et l'utilisations de pattes découpées (68, 69) sur les dents pour faciliter la torsion. L'invention concerne également un appareil de fabrication de contacts plans en forme de fourche spécialement en utilisant le procédé de l'invention.
