• a plug element made of electrically non-conductive material, preferably made of plastic
• the first electrical contacts are not only electrically insulated from one another, but are also held rigidly at a defined distance from one another. Since the plug element is formed directly on the fastening means, the electrical contacts are also positioned rigidly with respect to the fastening means. This has the advantage that the electrical contacts can be mounted by gripping the fastening means and inserting or plugging the plug element onto the electrical contacts on the iron.
• the second electrical contacts are held on a second plug element which is complementary to the first plug element, in particular in the rear region of the sole.
• a second plug element which is complementary to the first plug element, in particular in the rear region of the sole.

This not only shortens the assembly time, but also reduces the number of parts. This has the advantage that the irons according to the invention can be manufactured more cheaply.
• the invention includes the further essential idea of providing a special spacer between the metal sole and the heat-sensitive plastic housing in the rear area of the iron, where the heating resistors are usually arranged and the heating energy for heating the metal sole is entered.
• This spacer can also be used as a load-bearing connection between the two main parts of the iron. For this purpose, it is screwed in particular to the metal sole on the one hand and the plastic housing on the other.
• the spacer acts as a thermal separator between the metal sole and the plastic housing due to the ability to cause considerable heat radiation over its relatively large extent and / or because of its limited thermal conductivity.
• the bracket is made of either a metal with relatively (i.e., for a metal) low thermal conductivity or a highly heat-resistant plastic.
• the plastic version is preferably an injection molded part.
• the holding bracket has a substantially trapezoidal shape in plan view, for example with an approximately rectangular plate for connection to the metal sole at one end and a wide metal strip for connection to the plastic housing at the other end.
• a recess for cable routing is preferably provided centrally.
• both the mounting plate on the sole side and the mounting strip on the housing side aligned horizontally, and they are connected to one another by connecting webs which rise obliquely from the sole to the rear, so that overall there is approximately the basic shape of an elongated "S". From a thermal point of view, it is important that the fastening points for connection to the plastic housing are located horizontally (laterally) and vertically far from the heated metal sole.
• a second holding bracket attached to the metal sole and connected to the plastic housing is provided near the front end of the iron. Due to the usual design of irons, these irons cannot be as elongated and effective in their heat dissipation as the first retaining bracket, so that their combination with a spacer made of highly heat-resistant plastic at the screwing point with the plastic housing is preferred.
• a major advantage of the proposed solution is that the plastic housing can be made from only moderately heat-resistant and therefore inexpensive plastic, for example polypropylene.
• the effective thermal separation of the plastic housing from the metal sole, particularly in the rear area, tends to increase the service life.
• the provision of the relatively long metal bracket as a fastening means for the plastic housing also increases the comfort of the bracket because of the elasticity of the bracket, and also improves the shock resistance of the entire iron, which is positive, for example, in the drop tests required for approval in the USA and Canada noticeable.
• first and / or second retaining bracket has centering openings in the vicinity of the screw holes, and the plastic housing or the spacer placed therebetween have centering lugs for engaging in these centering openings. This ensures an exact positioning of the plastic housing relative to the metal sole via the respective bracket.
