An electrical connection for an electrical component in an exhaust gas system. The exhaust gas system has a metal casing through which an electrical conductor is routed. The connection has the conductor, an electrical insulation surrounding the conductor, and a metal bushing surrounding the insulation and the conductor, all together extend along a center axis. The insulation extends along the center axis beyond the bushing by an insulation gap of at least 2 mm at least at a first end of the connection.

A braze-free substrate heating device including a heater block body, a heater block lid, and a heating element. The heating element sits inside the heater block body. The heater block lid is on the heating element, such that the heating element is sandwiched between the heater block lid and the floor of the heater block body. The heating element is held in place by compressing the heater block lid into the heater block body and attaching the heater block lid to the top of the heater block body so that the heating element is fully supported over its surface area, and can maintain uniform thermal contact with the heater block lid and heater block body over its entire surface area.
