Abstract

A method of operating a hydraulically or electric motor operated tool includes providing a device shaft having electrical contacts; providing an accumulator having an adapter comprising a wall thereon; latching the adapter to the device shaft by a latching part; and engaging a tool with the latching part thereby detaching the adapter from the device shaft, whereupon during engagement of the tool with the latching part, the wall of the adapter is destroyed. When the device shaft and adapter are engaged, walls of the device shaft and adapter form an internal cavity and the latching part is positioned entirely therewithin such that the latching part is completely hidden from view. A hydraulically or electric motor operated tool is also disclosed.

First claim

The invention claimed is:

1. A method of operating a hydraulically or electric motor operated tool comprising:
providing a device shaft having a wall and at least first and second electrical contacts;
providing an accumulator, the accumulator having an adapter comprising a wall thereon;
latching the adapter to the device shaft by a latching part, wherein the wall of the device shaft and the wall of the adapter are proximate to each other and form an internal cavity when the device shaft and the adapter are connected together, the latching part being positioned entirely within the internal cavity such that the latching part is completely hidden from view by the walls of the connected together device shaft and adapter; and
engaging a tool with the latching part thereby detaching the adapter from the device shaft, whereupon during engagement of the tool with the latching part, the wall of the adapter is destroyed.

2. The method according to claim 1 , further comprising:
acquiring values relating to temperature and/or charging status of the accumulator by using contacts provided on the adapter; and
transmitting the values by using contacts provided on the adapter.

3. The method according to claim 1 , further comprising:
interrupting a power supply to the tool by using the adapter.

4. The method according to claim 1 , further comprising:
automatically actuating a power switch of the accumulator as a function of a condition datum of the accumulator.

5. The method according to claim 1 , further comprising:
automatically actuating a power switch of the accumulator as a function of a temperature and/or a charging status of the accumulator.

6. The method according to claim 1 , further comprising:
charging the accumulator with a plugged-in adapter, wherein the accumulator is connected with a charging device via the adapter.

7. The method according to claim 1 , further comprising:
outputting a signal from the adapter.

8. The method according to claim 7 , wherein the signal is a light and/or audio signal.

9. The method according to claim 1 , wherein the hydraulically or electric motor operated tool is a crimping device.

10. A hydraulically or electric motor operated tool comprising:
a device shaft having a wall and at least first and second electrical contacts;
an adapter comprising a wall;
an accumulator connected to the adapter; and
a latching part configured to connect the device shaft and the adapter together,
wherein the latching part can be released by engagement of a tool with the latching part, and
wherein the walls of the device shaft and the adapter are proximate to each other and form an internal cavity when the device shaft and the adapter are connected together, the latching part being positioned entirely within the internal cavity such that the latching part is completely hidden from view by the walls of the connected together device shaft and adapter, and wherein the wall of the adapter is destroyed when the latching part is engaged with the tool in order to detach the adapter from the device shaft.

11. The hydraulically or electric motor operated tool according to claim 10 , the adapter further comprising contacts configured to acquire values relating to temperature and/or charging status of the accumulator, the contacts capable of transmitting the values.

12. The hydraulically or electric motor operated tool according to claim 10 , wherein the adapter is capable of interrupting a power supply to the hydraulically or electric motor operated tool.

13. The hydraulically or electric motor operated tool according to claim 10 , wherein the accumulator has a power switch.

14. The hydraulically or electric motor operated tool according to claim 13 , wherein the power switch automatically actuates as a function of a condition datum of the accumulator.

15. The hydraulically or electric motor operated tool according to claim 13 , wherein the power switch actuates as a function of a temperature and/or a charging status of the accumulator.

16. The hydraulically or electric motor operated tool according to claim 10 , wherein the accumulator can be charged with a plugged-in adapter, wherein the accumulator is connected with a charging device via the adapter.

17. The hydraulically or electric motor operated tool according to claim 10 , wherein the adapter is capable of outputting a signal.

18. The hydraulically or electric motor operated tool according to claim 17 , wherein the signal is a light and/or audio signal.

19. The hydraulically or electric motor operated tool according to claim 10 , wherein the hydraulically or electric motor operated tool is a crimping device.

20. The hydraulically or electric motor operated tool according to claim 10 , wherein the wall of the adaptor is continuous.

21. The hydraulically or electric motor operated tool according to claim 10 , further in combination with a tool which is used to engage the latching part.
