Abstract:
A circuit assembly (600) includes a printed circuit board assembly (100). The printed circuit board assembly includes a first circuit board (101), a second circuit board (102), and a first flexible substrate (103) interposed between, and continuous with, the first circuit board and the second circuit board. A second flexible substrate (108) extends from, and is continuous with, the second circuit board. One or more electronic circuits comprising electronic components (301,302,303,304,305) are disposed along one or more of the first circuit board or the second circuit board. The printed circuit board assembly is folded about a battery (601), with the first circuit board adjacent to the first major face, the second circuit board adjacent to the second major face, and the first flexible substrate spanning the one or more side faces.

A modular power device is used for mounting on a main plate. The modular power device includes a first substrate, a driving module, and a converting module. The first substrate having a first axial direction and a second axial direction perpendicular to the first axial direction is inserted into the main plate to make the second axial direction be perpendicular to the main plate. The driving module is located on one side of the first substrate, and the converting module is located on the other side of the first substrate and includes a second substrate, wherein the second substrate is inserted into the main plate. A length of the converting module is substantially equal to that of the first substrate in the first axial direction, and a width of the converting module is smaller than a length of the first substrate in the first axial direction.

Along the bent part, there are prominent parts to fix the connector in the hole in the plastic board. The board for the insertion of an electronic connector, which has multiple holes with an extruded part in each hole on which to fix the electronic connector, is included.
Abstract:
A protector panel receives plug-in protector modules. The panel has a plurality of pin receiving holes. The panel has a plurality of members depending from its bottom. Each of the at pin receiving holes has a respective pair of the depending members adjacent to and on opposite sides of that hole. Each member has a boss at an end of the member. A printed wiring board is attached to the panel, beneath the depending members. The printed wiring board has wirings on its surface. The printed wiring board has a plurality of holes, each aligned with a respective pin receiving hole of the panel. The printed wiring board has a resilient elongated member adjacent to each hole of the printed wiring board. The elongated members, which ensure electrical contact between the pins and wiring on the printed wiring board, have a conductive material on them. The conductive material forms an electrical connection between the wirings and pins of the plug-in protection devices, while the pins are at least partially inserted into the holes of the panel.
Abstract:
A method of forming an electrical backplane comprising providing an initially oversized ground and potential plate, forming discontinuous slots in a staggered relationship near the edges of the top surface of one of the plates and the bottom surface of the other plates, laminating the plates together by filling the slots with insulative material and trimming the edge portions off by cutting through the filled slots and webs connecting the slots whereby exposed backplane edges lie opposite insulation in the slots of the plates.
Abstract:
A capacitive switch includes: an electrical circuit formed by two spaced pads of conductive material on an insulative substrate; and a capacitive coupling member on the end of a keystem wherein the end of the keystem has a looped ribbon formed by two layers of insulating material sandwiching a layer of conductive material. As the keystem is urged toward the substrate a monotonically increasing area of the ribbon mechanically contacts the pads so that a monotonically increasing capacitive coupling is made between the two spaced pads.
Abstract:
An electrical matrix board of dielectric material having a printed circuit defined upon two surfaces thereof and including a plurality of metallic terminals defined thereon in a plurality of sets, the terminals being related such that each set includes a central terminal surrounded by secondary terminals arranged in a hexagonal configuration, and the distance between adjacent secondary terminals defining a set, and between such secondary terminals and the associated primary terminal being equal. The terminals include connection means, preferably in the form of an axial passage, a portion of which may be threaded to receive a screw connector. The terminal sets are arranged on the matrix board in groups, whereby a printed circuit interconnects the primary terminals of sets in different groups, and selected terminals of sets within the same group are also interconnected by a printed circuit. Bridge means permits interconnection of selected terminals within the same set or group and the printed circuits include taps disposed adjacent the edge of the matrix board for connecting the board into other circuitry.

A modular power device is used for mounting on a main plate. The modular power system includes a first substrate, a driving module and a converting module. The first substrate having a first axial direction and a second axial direction substantially perpendicular to the first axial direction is inserted into the main plate, such that the second axial direction is substantially perpendicular to the main plate. The driving module is located on one side of the first substrate and electrically connected thereon. The converting module is located on the other side of the first substrate and electrically connected to the driving module.

Abstract:
A two-side cable-arrangement structure is disclosed. The two-side cable-arrangement structure includes a plate, a first cable-arrangement structure, and a second cable-arrangement structure. The first cable-arrangement structure and the second cable-arrangement structure are respectively disposed on two sides of the plate. A cable is fixed on the two sides of the plate by the first cable-arrangement structure and the second cable-arrangement structure simultaneously. Thereby, the cable is constrained at both the direction vertical toward the plate and the direction vertical away from the plate, and the fixed cable is not easy to move by pulling. It solves the difficulty of fixing a cable completely by a conventional single-side cable-arrangement structure in the prior art.
