Tool

Abstract

The invention relates to a hydraulically or electric motor operated tool ( 1 ), for example a crimping device, with a device shaft ( 2 ) that exhibits at least a first and second electrical contact, and with an accumulator ( 3 ) that can be latched with the device shaft ( 2 ), wherein an adapter ( 4 ) that can be secured by a latching connection to the device shaft ( 2 ) and accumulator ( 3 ) is provided on the device shaft ( 2 ) between the device shaft ( 2 ) and accumulator ( 3 ). In order to indicate a favorable connection between an adapter and a device shaft of such a device, it is proposed that the latched connection with the device shaft ( 2 ) can only be released by acting on a detaching part situated inside the adapter ( 4 ).

1 . A hydraulically or electric motor operated tool comprising:
 a device shaft having at least first and second electrical contacts;   an accumulator capable of being latched with the device shaft:   an adapter capable of being secured by a latching connection to the device shaft and to the accumulator, said adapter provided between the device shaft and the accumulator;   wherein the latching connection with the device shaft can only be released by acting on a detaching part provided inside the adapter.   
     
     
         2 . The tool according to  claim 1 , wherein latching connection cannot be released without destroying part of the adapter. 
     
     
         3 . The tool according to  claim 1 , wherein the latching connection can only be released by a tool that engages into an interior of the adapter. 
     
     
         4 . The tool according to  claim 1 , wherein at least a side of the adapter facing the accumulator exhibits contacts for acquiring values about the temperature and/or charging status of the accumulator, said contacts capable of transmitting said values. 
     
     
         5 . The tool according to  claim 1 , wherein the adapter is capable of interrupting a power supply to the tool. 
     
     
         6 . The tool according to  claim 1 , wherein in the accumulator has a power switch. 
     
     
         7 . The tool according to  claim 6 , wherein the power switch automatically actuates as a function of a condition datum of the accumulator. 
     
     
         8 . The tool according to  claim 6 , wherein the power switch actuates as a function of a temperature and/or a charging status of the accumulator. 
     
     
         9 . The tool according to  claim 1 , wherein the accumulator can be charged with a plugged-in adapter, wherein the accumulator is connected with a charging device via the adapter. 
     
     
         10 . The tool according to  claim 1 , wherein the adapter is capable of outputting a signal. 
     
     
         11 . The tool of  claim 10 , wherein said signal is a light and/or audio signal. 
     
     
         12 . The tool of  claim 1 , wherein said tool is a crimping tool. 
     
     
         13 . A hydraulically or electric motor operated tool comprising:
 a device shaft having at least first and second electrical contacts;   an accumulator capable of being latched with the device shaft; and   an adapter capable of being secured by a latching connection to the device shaft and to the accumulator, said adapter provided between the device shaft and the accumulator, said adapter is capable of interrupting a power supply to the tool.   
     
     
         14 . The tool of  claim 13 , wherein said tool is a crimping tool. 
     
     
         15 . A hydraulically or electric motor operated tool comprising:
 a device shaft having at least first and second electrical contacts;   an accumulator capable of being latched with the device shaft; and   an adapter capable of being secured by a latching connection to the device shaft and to the accumulator, said adapter provided between the device shaft and the accumulator, the adapter is capable of outputting a signal.   
     
     
         16 . The tool of  claim 15 , wherein said signal is a light and/or audio signal. 
     
     
         17 . The tool of  claim 15 , wherein said signal relates to values about the temperature and/or charging status of the accumulator. 
     
     
         18 . The tool of  claim 17 , wherein said tool is a crimping tool. 
     
     
         19 . The tool of  claim 15 , wherein said tool is a crimping tool.
