The invention relates to a device in an industrial robot where it is desired rapidly to exchange tools in spite of the fact that the tools from the robot arm are supplied with both electric and pneumatic operating pulses. The robot hand supports a housing (3) and a tool holder attachment (6) rotatably journalled in the housing (3), a tool holder (7) being detachably arranged in the tool holder attachment (6). According to the invention, an automatically breakable electrical connection is provided between the housing (3) and the tool holder (7) by means of slip rings (9) arranged on either the housing (3) or the tool holder (7) and by means of corresponding collector shoes (10), arranged on that one of said two parts (6,7) which does not carry the associated slip rings and adapted to make contact with said associated slip rings (9) on insertion of the tool holder (7) into the tool holder attachment (6). |
