An electrical lead-through for an electronics housing, comprises a first stop element with at least one first through-hole, a second stop element with at least one second through-hole, an elastic element which extends between the first stop element and the second stop element along a first axis, and at least one electrical contact element with a first end and a second end lying opposite the first end. The first end of the contact element is movably arranged in the first through-hole and the second end is movably arranged in the second through-hole. The elastic element is suitable for deforming when the first stop element and the second stop element are moved relative to each other, and the first stop element and the second stop element are each suitable for being fixed to the electronics housing.

Electrical lead-through and electronics housing

An assembly comprises a circular panel; an annular body; and an elastomer ring. The annular body has a panel seat surrounded by a lateral surface having a ring shaped outer groove bounded in a first axial direction by a first outer shoulder and bounded in an opposing, second axial direction by a second outer shoulder. Adjoining the first outer shoulder is a guide surface having a radius monotonically increasing with separation from the first shoulder. The circular panel has an outer lateral surface having a peripheral inner groove extending radially inwards. The two inner shoulders have a convex contour in which the rotational axis of the circular panel extends. The elastomer ring is clamped between both inner shoulders and both outer shoulders, whereby a shifting of the circular panel out of the annular body is prevented up to a limit loading.

A connection apparatuscomprisesincludes:a platform,;a plug connector having a plug connector part secured to the platform and electrically connected to the circuit of the field device and a plug connector part connectable withtheaconnection cable and complementary to the first plug connector part, as well as; anda lidheld movablymoveablerelative to the platform for at least partially covering the plug connectorformed by connecting the plug connector parts. The lid is swingable between a first end position, in which the lid at least partially covers the plug connector, and a second end position, and isadditionallyadapted inat least oneanopen position located between the first end position and the second end position to expose the plug connector such that the plug connector part can be separated from the plug connector part,as well asand,at least in the first end position,to secure the plug connector part connected with the plug connector part.

Connector apparatus for a field device as well as field device with such a connector apparatus

A housing of a field device of measuring- and automation technology, comprising a housing body, which has at least two housing chambers, wherein the housing chambers are connected together by an opening. The opening is adapted to accommodate a circuit board which is held by at least one holder, wherein the circuit board is adapted to be populated with electronic components or assemblies. The opening is Ex-d sealed with a potting compound.

Housing for a field device

The connection apparatus of the invention comprises a platform (), a plug connector () having a plug connector part () secured to the platform () and electrically connected to the circuit of the field device and a plug connector part () connectable with the connection cable and complementary to the first plug connector part (), as well as a lid () held movably relative to the platform () for at least partially covering the plug connector () formed by connecting the plug connector parts ().
