A wireless dongle for use in the potentially explosive area for an automation field device to connect to an electrical interface of the field device, having a wireless circuit for sending and receiving wireless signals and a connector element. The wireless dongle can be detachably fitted to the electrical interface by means of the connector element. The connector element has several contact elements, wherein the contact elements are attached to a printed circuit board in the wireless dongle, that a first contact element is used to supply the wireless dongle with energy, that an energy buffer on the printed circuit board is provided which is downstream of the first contact element. The connector element has a second contact element which is used to transmit data between the field device and the wireless dongle, that in each case there is at least one limiting resistor is downstream of the first contact element and the second contact element, and that the resistors and the energy buffer of the wireless dongle are encapsulated by means of a potting compound.

The invention relates to an electronic control unit. A back-up power supply for the electronic control unit is defined by at least two capacitors. The at least two capacitors are accommodated in a housing part of the electronic control unit. A first insulation displacement connector is positioned in a first tower, and a second insulation displacement connector is positioned in a second tower. A first electric line of each capacitor is connected to the first insulation displacement connector, and a second electric line is connected to the second insulation displacement connector.

A filtered feedthrough comprises an insulator sealed in a ferrule opening. A terminal pin sealed in an insulator via hole has a first end that extends outwardly beyond an insulator device side. A filter capacitor has a square- or rectangularly-shaped dielectric supporting interleaved active and ground electrode plates. A passageway extending through the dielectric has an internal metallization. An external metallization is contacted to opposed longitudinal sides of the dielectric outer surface. The capacitor ground electrode plates extend to the opposed external metallizations. The outwardly extending terminal pin end is connected to the internal metallization in the dielectric passageway which in turn is connected to the active electrode plates. A conductive material connects the capacitor external metallization at one of the longitudinal sides to an oxide-resistant surface on the ferrule while the other external metallization is connected to an oxidized surface of the ferrule.

A connector device electrically connected to a circuit board includes: a body portion connected externally; a housing surrounding at least a portion of the body portion; a first terminal extending downward from the body portion and connected to a first capacitor of the circuit board; a second terminal extending downward from the body portion to be spaced apart from the first terminal and connected to a second capacitor of the circuit board; and a ferrite core through which the second terminal passes.

An improved method and structure for forming an electrical interconnects mechanism in a Power Distribution Network (PDN) by placing capacitors on the top of the pin array on the printed circuit board (PCB) of the structure to decouple the PDN and results in lower impedance benefitting the frequency range of the PDN effecting a significant performance improvement in the spring-pin inductance from the transmission line. This reduction in impedance reduces the power supply ripple.

A method of manufacturing a terminal module and a connector assembly having the terminal module. The terminal module includes first signal terminals and conductive terminals formed individually. Each first signal terminal includes a first body portion, a first soldering portion and a tail portion. Each conductive terminal includes a second body portion, a contact portion and a second soldering portion. The conductive terminals include second signal terminals. The first soldering portion of each signal terminal and the second soldering portion of each second signal terminal are provided to be separate and form an interval therebetween, and an electronic component is provided at the corresponding interval, without the need to cut the middle portions of the signal terminals by a cutting blade to form a broken recess, thus being convenient for the manufacturing of the terminal module, and improving the electrical characteristics of the terminal module.
