Definitions

  • the present invention relates to an interface element for mounting arrangement and electrical connection of electronic components, and also to an arrangement for mounting and electrical connection of electronic components including an interface element, the purpose of which is to eliminate the need for electrical wiring usually involved in the electrical connection of these electronic components.
  • Electronic components are the structure of an electronic circuit, that is, they are the components that are part of any electrical or electronic circuit (from the simplest to the most complex) and that are interconnected with each other.
  • An electronic component can also be defined as any electrical device that transmits electric current through or through a conductor or semiconductor.
  • PCB printed circuit board
  • a printed circuit consists of a board formed by layers of plastic and fibrous materials (such as phenolite, glass fiber, polyester fiber and film, among other polymers) that has thin films of metallic substances (copper, silver, gold or nickel). These films form the “trails” or “tracks” that are responsible for conducting the electric current through the electronic components. These electrical impulses are transmitted to the components, enabling the operation of each part and, consequently, of the complete system formed by the PCB.
  • plastic and fibrous materials such as phenolite, glass fiber, polyester fiber and film, among other polymers
  • metallic substances copper, silver, gold or nickel
  • said PCB's are usually also associated with electrical connectors, responsible for providing the electrical connection between said PCB and some other electro-electronic component, for example, pressure sensors, temperature sensors, vibration sensors, among many other possible ones.
  • an electrical connector Normally, an electrical connector consists of two parts attached to a rigid or flexible object, such as a cable, for example. In general, these two parts are connected through a pin and a socket, which involves the pin in order to maintain physical contact and electrical conduction satisfactorily. More specifically, electrical connectors are typically designed such that the component receptacle has male metal blades or pins and the harness receptacle has female counterparts.
  • connectors There are several different types of connectors. The best known are the RCA that are generally used to make the connection between TV sets, VCRs, DVD players, and even computer video cards. There are also connectors for computer network cables, VGA connectors (mostly used to connect a computer's video card to a monitor), SVGA connectors (also used for connection between computer video cards and monitors, but it can also connect TV , projectors, DVD, etc.), among others.
