Contact connection adapter for producing an intermittent electrical contact between two plugs

1. A contact connection adapter for producing an intermittent electrical contact between a first plug ( 2 ), particularly a standard terminal plug of a cardiac pacemaker electrode ( 3 ), and at least one further plug ( 4 , 5 ), particularly a typical laboratory plug of a laboratory cable for intermittent connection of the electrode ( 3 ) to a stimulus threshold analyzer, comprising

a main body ( 6 ),

a first socket-like receptacle ( 7 ), which is placed in the main body ( 6 ), for the first plug ( 2 ), and

at least one second socket-like receptacle ( 18 , 19 ), which is placed in the main body ( 6 ), for the at least one further plug ( 4 , 5 ), the cross-sections of the first and the at least one second receptacles ( 7 , 18 , 19 ) intersecting peripherally in such a way that plugs ( 2 , 4 , 5 ) plugged into the receptacles ( 7 , 18 , 19 ) press against one another at their lateral contact faces ( 14 , 15 , 27 ) and produce an electrical contact.

2. The contact connection adapter according to claim 1 , wherein the receptacles ( 7 , 18 , 19 ) for the plugs ( 2 , 4 , 5 ) are situated having their longitudinal axes in planes (P 7 , P 18 , P 19 ) intersecting one another perpendicularly.

3. The contact connection adapter according to claim 1 , wherein, for a bipolar or unipolar plug ( 2 ), a receptacle ( 7 ), whose diameter (d 11 , d 12 ) is stepped twice with increasing socket depth, is provided for its adaptation to diameters (D 13 , D 14 , D 15 ), which are reduced in steps, of plug shaft ( 13 ), annular contact ( 14 ), and tip contact ( 15 ) of the plug ( 2 ).

4. The contact connection adapter according to claim 1 , wherein the first socket-like receptacle ( 7 ) for the first plug ( 2 ) is open both at a deep end in a longitudinal axial direction via a thin passage ( 30 ) and also along its entire depth via a lateral, longitudinally parallel passage slot ( 29 ).

5. The contact connection adapter according to claim 1 , wherein the at 20 least one second receptacle ( 18 , 19 ) for the at least one further plug ( 4 , 5 ) has an opening at a deep end ( 23 , 24 ).

6. The contact connection adapter according to claim 1 , wherein the main body ( 6 ) comprises a transparent, sterilizable plastic material.

7. The contact connection adapter according to claim 3 , wherein two receptacles ( 18 , 19 ), which lie parallel next one another, for two further plugs ( 4 , 5 ) are placed in the main body ( 6 ), which have an offset (V) to one another corresponding to a diameter reduction between annular contact ( 14 ) and tip contact ( 15 ) of the bipolar plug ( 2 ).

8. The contact connection adapter according to claim 4 , wherein the passage slot ( 29 ) is provided with insertion bevels ( 32 ).
