Abstract:
A surface mounting method which utilizes an adhesive component to mount the electrical components to a printed circuit board instead of solder and which includes the use, between the contacting surfaces, of a flowable, corrosion-resistant material which bridges contact imperfections and penetrates surface films. The method may also be implemented to connect two electrical conductors.
Abstract:
A double-sided flexible electronic circuit module is provided having a flexible printed circuit board. The flexible circuit board has a plurality of conductive paths on each surface and a plurality of conductively plated-through apertures being connected to the conductive paths. One side of the flexible circuit board is adapted to carry components with leads; the other side of the flexible circuit board is adapted to receive components without leads. A carrier member, larger than the flexible circuit board and of a size and shape sufficient to accommodate the placement of at least one flexible circuit board, is also provided. The carrier member has a plurality of apertures which are in alignment with the apertures of the flexible circuit board, and a plurality of elongated slots in predetermined positions which extend the entire width of the flexible circuit board which is temporarily affixed onto the carrier member. All of the components are soldered to the flexible circuit board, the carrier member acting as a support member to the components having leads.
Abstract:
An arrangement for the mechanical fastening and electrical connection of a pellet, particularly a tantalum pellet, covered with a surface-adherent electrode, to a support. The electrode cannot be subjected to inertial forces of the pellet. An intermediate sheathing is positioned between the electrode and the support. The sheathing non-adhesively encompasses the pellet in a form-fitting manner. The intermediate sheathing is glued to the support. The electrode is electrically connected with the support through a flexible conductor element.

PROBLEM TO BE SOLVED: To provide a novel electromagnetic relay of low profile which has a simple and rational configuration. SOLUTION: The electromagnetic relay 1 includes a body part consisting of a holding block 10 to which various components such as a coil are fitted and a cover 20 attached to it, with the appearance being a rectangular solid. Terminals 5, 6, 7, and 8, having plate-like structure protrude from the body part. They protrude from the first plane A extending parallel to the thinnest direction of the body part, bend to be parallel to the thinnest direction of the body part in the plane vertical to the plate thickness direction of the terminals 5, 6, 7, and 8 and then extend beyond the second plane B across the thinnest direction of the body part. Since the tips of the terminals 5, 6, 7, and 8 extending beyond the second plane B of the body part are mounted on a substrate 30, the electromagnetic relay 1 is secured in such manner as the thinnest direction of the body part is vertical to the surface of the substrate 30.

Abstract:
PROBLEM TO BE SOLVED: To improve vibration resistance by securely fixing a large-sized film capacitor upon packaging the film capacitor for use in a high voltage circuit on a printed board. SOLUTION: A resist 7 is formed on a printed board 1 with a predetermined thickness excluding an electrode opposing part 1a (Fig.a), and on the resist 7, a silk printing layer 9 is formed with a predetermined thickness (Fig.b). Thereafter, a recessed part 2b of a film capacitor 2 is stacked on the silk printing layer 9 with a predetermined thickness double-sided tape 6, and an electrode 2a of the film capacitor 2 is opposed to the electrode opposing part 1a of the printed board 1 (Fig.d). The total thickness of the resist 7, the silk printing layer 9, and the double sided tape 6 is made to be larger than the unevenness L1 of the film capacitor 2 to avoid interference between the electrode 2a of the film capacitor 2 and the printed board 1. Because no adhesive is used, it is possible to eliminate the problem of environmental load materials and also it is possible to remove difficulty accompanied by the management of the adhesive.

Abstract:
PROBLEM TO BE SOLVED: To provide an electronic component holder of advantage for manufacturability and economical efficiency without the increase in parts count or assembly man-day, and also without substantial increase in manufacturing cost, which can prevent the electronic component from omission by securing simply and firmly the lead of the electronic component. SOLUTION: The electronic component holder made of synthetic resin is constituted such that: two or more horizontal grooves 3 making the electronic component leads pass from an opening 6 in front of the holder are formed in an upper surface 7 of the holder, and two or more vertical grooves 4 making the electronic component leads pass by bending them almost at right angles are formed in a rear surface 8 of the holder. As a lead fixing means for carrying out pinch pressure fixing of the lead by using the resiliency of the synthetic resin, an electronic component holder H is used wherein synthetic resin ribs 13a and 13b are formed integrally along the vertical grooves 4 so that the width of the upper end of the vertical groove 4 may be made larger than the diameter of the lead, and the groove width of the lower end may be narrower than the diameter of the lead. Thus, the lead is fixed by pinch pressure fixing by using the resiliency of the synthetic resin ribs 13a and 13b so as to prevent the electronic component from omission. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
The invention relates to a holder for a button cell, wherein the holder is intended to be fastened on a printed circuit board, wherein the holder has at least two first latching arms which protrude from the printed circuit board when the holder is in the mounted state, wherein the button cell is received between the first latching arms when the button cell is in the mounted state, wherein the first latching arms, at one end, are each connected to a main body which has a base area which is connected to the printed circuit board when the holder is in the mounted state, wherein the first latching arms each have at least one first latching lug in order to hold the button cell on the printed circuit board, and wherein the first latching lugs are arranged at a first distance from the base area of the main body.
