Electronic module

Abstract

The invention relates to an explosion-proof electronic module (1) having a fast interface, and to a method for establishing electronic contact with said electronic module (1) via said interface. For this purpose, in addition to an electronic component (11), it comprises at least one electrical contact surface (12) for establishing electrical contact with said component (11), and also comprises anenclosure (13), which encloses at least the at least one electrical contact surface (12). The enclosure (13) here is configured, at least in a sub-region (131), such that contact can be established with the at least one contact surface (12) by means of at least one electrical contact pin (2), wherein the enclosure (13) is filled with an encapsulating compound (14) at least between the at least onecontact surface (12) and the sub-region (131). Therefore, the one or more electrical contact surfaces (12) give rise, according to the invention, to a physical interface to the electronic module (1)which, while not being subjected to the restrictions in respect of the explosion-protection-induced maximum transmission speed, can nevertheless provide explosion protection because it is reclosed bythe self-reclosing encapsulating compound (14) once the contact pin (2) has been removed.

Description

technical field [0001] The invention relates to an electronic module and a method for electrical contacting of such an electronic module. Background technique [0002] In automation technology, especially in process automation technology, field devices are often used which are used to record and / or influence process variables. For recording process variables, sensors are used, for example, in level measuring devices, flow measuring devices, pressure and temperature measuring devices, pH redox potential measuring devices, conductivity measuring devices and the like. It records the corresponding process variables such as fill level, flow, pressure, temperature, pH value, redox potential and conductivity. Used to influence process variables are actuators, such as valves or pumps, via which the flow of liquid in a pipe, pipe, or line section or the level of fill in a container is changed. In general, all devices are referred to as field devices, which are applied near the proc...

Therefore, the data transmission speed of this explosion-safe interface is also limited

However, in the case of manufacturing electronic modules, this is disadvantageous because it significantly slows down the manufacturing step of programming (also called "flashing"): when programming of electronic modules (usually based on microcontrollers or FPGA) e.g. via a suitable non-explosion-proof, JTAG- or "Spy Bi Wire" interface takes place within seconds, e.g. a suitable data transfer via an explosion-resistant digital interface takes more than 10 minutes
