Abstract
A plug adapter for plugging a connecting lead having at least two poles onto a switching device having a respective secondary contact, for a respective lead conductor, disposed parallel to a combination plug-in orifice includes, on a bottom side facing the switching device, a housing cutout. Associated with each of the at least two poles is a respective access contact including a contact spring. The access contact has a housing opening, and a respective plug, a respective conductor bar. The free end of the contact spring is elastically preloaded, and a damping device is configured to simultaneously clamp the lead conductors to the contact spring and actuatable via an actuator bracket.

A plug adapter for plugging a connecting lead having at least two poles onto a switching device having at least two poles,
- the switching device having associated with each of the at least two poles:
- a respective input-side terminal contact and a respective output-side terminal contact on an access side of the switching device, and
- a respective secondary contact configured for a lead conductor of the connecting lead, the secondary contact being disposed parallel to a combination plug-in orifice disposed on a top side of the switching device perpendicular to the access side, and being accessible to at least one of the respective input terminal contact and the respective output terminal contact,
- the plug adapter comprising:
- on a bottom side facing the switching device, a housing cutout having a breadth of the plug adapter, a width corresponding to a distance between the combination plug-in orifice and a top edge of the access side of the switching device, and a height extending from the top edge of the access side of the switching device to entry slots of the terminal contacts so as to provide access to the entry slots;
- and
- associated with each of the at least two poles:
- a respective access contact for the lead conductor of the connecting lead, the access contact being disposed in a clamping chamber and including a contact spring having a free end, the access contact having a housing opening parallel to an entry slot of the terminal contact;
- a respective plug contact configured to plug onto the secondary contact of the switching device;
- a respective conductor bar disposed between the access contact and the plug contact, the free end of the contact spring being elastically preloaded against the conductor bar;
- and
- a clamping device configured to simultaneously clamp the lead conductors to the contact spring and actuatable via an actuator bracket configured to act on a hold-down clamp so as to displace the free end of the contact spring away from the conductor bar.
