Abstract:
An electrical connector having a metal plate which is mounted under the housing with hot riveting. Location pegs are made so that low mounting force is possible. A wafer which is black in color or has another contrasting color makes it possible for a video camera to record the true position of the terminals. The surface of the top side of the housing is suited for vacuum pick up.
Abstract:
A molded circuit board formed by molding a resin substrate to one side of a circuit film made by forming a desired circuit pattern to an insulating film in a manner to form an integral body. In the circuit film, there are provided soldering pad regions for mounting surface-mounting parts in a surface of the circuit film opposite the other surface in contact with resin substrate and through-holes at locations of the circuit film where insert-mounting parts are mounted. In the resin substrate, holes for receiving insert-mounting parts are formed in the molding process at the locations corresponding to the through-holes of the circuit film.
Abstract:
Disclosed is apparatus for mounting electronic device packages and heat sinks on printed circuit boards with the pin connectors of the electronic device package held in alignment with preformed locations on the printed circuit boards. The alignment apparatus includes means for securing the electronic device package in intimate thermal contact with the heat sink for rapid dissipation of heat therefrom.
Abstract:
A flexible membrane is disclosed which extends over an aperture in a support plate in an electromagnetic sealed contact matrix or ferreed type switch. The ferreed switch includes at least one circuit path element and the flexible membrane joins the circuit path element to the support plate and extends the circuit path element over the aperture to a point of rigid contact with a conductor lead projecting from an associated sealed contact switch.
Abstract:
The invention relates to a pin (2) having a contact part that can be inserted into a receiving opening (20) in a circuit board (4) and anchored with a press fit in the receiving opening (20), and to a method for inserting a pin into a receiving opening (20) in a circuit board (4), wherein the pin (2) is inserted into the receiving opening (20) from one side of the circuit board (4) and a contact part (24) of the pin (2) is anchored in the receiving opening (20) with a press fit. According to the invention, the contact part (24) is inserted into the receiving opening (20) with no contact or with a sliding fit and subsequently deformed within the receiving opening (20) by expansion transversely to the insertion direction, in order to anchor it in the receiving opening (20) with a press fit.
Abstract:
A board, for example a printed circuit board 10 for insertion into a telecommunication module in an insertion direction 100, the printed circuit board 10 comprising a substrate 20, having two major surfaces 92, 94, first and second conductive paths 30, arranged on a major surface of the substrate 20, for electrically contacting first and second resilient contact elements of a linearly-arranged row of resilient contact elements of the telecommunication module, wherein the first and second conductive paths 30 are arranged such that a contacting end 35 of each of the conductive paths 30 is located on a straight reference line 110 which is substantially perpendicular to the insertion direction 100, so that electrical connections between respective resilient contact elements and the respective conductive paths 30 are established at one single insertion depth. The substrate 20 is shaped such that mechanical engagement between parts 25 of the substrate 20 which are to engage mechanically with the first and second resilient contact elements, respectively, and respective resilient contact elements is completed at different insertion depths of the board into the telecommunication module.
