Abstract:
A multilayer circuit board includes a first substrate and a second substrate in stack. The first substrate has a first pad, and a first circuit, wherein the first circuit is embedded in the first substrate, and the first pad is electrically connected to the first circuit. The second substrate has a first through hole, a second pad, and a second circuit, wherein the first through hole is opened at both sides of the second substrate, and the first pad of the first substrate is in the first through hole; the second circuit is embedded in the second substrate, and the second pad is electrically connected to the second circuit. The pads on each substrate are exposed by the through hole(s) of the above substrate(s) to shorten the null sections of the interconnectors and reduce the interference from the null sections.
Abstract:
A printed board with board terminal having a novel structure, capable of lowering the support position of an electrical component supported on a printed board and enabling electrical components to be mounted on both sides of the printed board while reducing height, and an electrical connection box using the same is provided. The printed board 34 includes through holes 62 through which tab terminals 76 are inserted. A board terminal 32 includes an insertion hole 38 into which the tab terminal 76 is inserted and a connecting portion 42 projecting inwardly of the insertion hole 38 is pressed into contact with the tab terminal 76. A tab terminal inserting portion 72 is formed by arranging the through hole 62 and the insertion hole 38 such that the through hole 62 and the insertion hole 38 overlap each other in a plan view.
Abstract:
In a relay module device, a signal converting section transmits driving signals of switching elements when receiving input signals from an external device and sets a relationship between the input signals and the driving signals. The relationship includes a first mode in which the signal converting section transmits the driving signals to separately control one of the switching elements with respect to one of the input signals, and a second mode in which the signal converting section transmits the driving signals to concurrently control two or more of the switching elements with respect to one of the input signals.
Abstract:
A printed circuit board includes: a first electrode made of a tubular electric conductor formed on an inner wall of a first hole formed in the printed circuit board; a dielectric body disposed inside the first electrode; and a second electrode made of a tubular electric conductor formed on an inner wall of a second hole extending through the dielectric body, the second electrode having a center axis concentric with the first electrode.
Abstract:
A printed circuit board includes a surface and having first and second adjacent apertures. First and second electrical terminals include respective ends disposed in the first and second apertures of the printed circuit board, respective shoulders adjacent to the ends of the first and second electrical terminals and engaged with the surface of the printed circuit board, and respective insertion tabs adjacent to the shoulders of the first and second electrical terminals and located respective first and second distances away from the surface of the printed circuit board. The first and second distances are different such that the first and second insertion tabs do not touch one another.
Abstract:
A circuit module for connecting to a circuit board is disclosed, the circuit module for connecting to a circuit board, wherein the circuit module comprises a substrate having a top surface, a bottom surface and a lateral surface connecting the top surface and bottom surface, wherein at least one electrical component is disposed on the top or bottom surface and a plurality of surface-mount pads are disposed on the lateral surface of the substrate for electrically connecting to corresponding pads on the circuit board.
Abstract:
A reverse tapered mounting tab for a signal connector is disclosed. The signal connector includes the reverse tapered mounting tab coupled to a connector body having a connector port inside. The reverse tapered mounting tab is configured to be secured in a through hole of a circuit board. Solder may be positioned in the through hole after positioning the mounting tab. The solder may prevent the mechanical tab from being forced through the through hole even after minor cracking and deformations in the solder.
Abstract:
Electrical contact arrangement for an electric motor and method for producing same. The present invention relates to an electrical contact arrangement for an electric motor, in particular for an EC drive of a motor vehicle fan, comprising an elongate contact which runs perpendicular to a planar basic conductor, wherein the basic conductor is in the form of a leadframe, and a conductive cohesive and/or form-fitting and/or force-fitting connection is provided between the leadframe and the contact. The present invention also relates to a method for the production of said electrical contact arrangement.
Abstract:
An electrical connector includes an insulative housing, a contact module, and a magnetic module. The insulative housing defines a receiving cavity forwardly communicating with an exterior plug and a mounting cavity located behind the receiving cavity. The contact module includes a set of mating contacts each having a contacting portion exposed within the receiving cavity and a set of mounting contacts for connecting to an exterior substrate. The magnetic module is received in the mounting cavity and electrically connecting the mating contacts to corresponding mounting contacts. The magnetic module includes a printed circuit board (PCB) and four isolated transformers surface mounted on a same face thereof. The four discrete transformers are arranged on a limited space of the PCB.
