US 11,600,944 B2 · Electrical feedthrough and medical device

Abstract

An electrical feedthrough (1) is provided for improving the thermal properties and the electromagnetic compatibility (EMC) and also for simplified production of a medical instrument (7), in which electrical feedthrough individual contact pins (4), which are guided through a glass body (2) in a housing (20) of the instrument (7), are electrically connected to one another by a pluggable plug element (5), preferably in the form of a sheet metal part. Here, the plug element (5) firstly provides high thermal and electrical conductivity and secondly provides a shielding area that effectively prevents the input coupling of electromagnetic radiation. Preferably, the plug element (5) is formed in such a way that it independently develops a holding force for securing itself to the contact pins (4).

Dependent claims

An electrical feedthrough (1) for a medical device, the electrical feedthrough (1) comprising:

a sealing glass body (2);
an arrangement (3) of electrical contact pins (4) molded into the glass body (2) that penetrate through the glass body (2);
and
a metallic plug element (5) plugged onto at least two of the contact pins (4), which protrude from the glass body (2) on at least one of an inner or outer side thereof, the metallic plug element and the at least two of the contacts are cohesively connected to the at least two contact pins (4) such that the at least two contact pins (4) are electrically connected to one another in a completed assembly of the feedthrough.
