Problems solved by technology
Damage to the protective conductor when the tightening torque is too high, which can lead to breakage of the protective conductor
Furthermore, the protective conductor can also be fastened on the wrong side of the screw, so that the protective conductor is undesirably pressed outwards
[0011] In addition, the protective conductor connected to the grounding element can only be loosened with the help of a screwdriver as it is fixed, which has the disadvantage of being cumbersome if necessary

Embodiment Construction
[0069] The figures include partially simplified schematic diagrams. In parts, the same reference numerals are used for identical, but possibly not identical, elements. Different views of the same elements may be shown at different scales.
[0070] Figure 1A Shown is an electrical connection contact 1 provided with a first and a second support pin 110 suitable for a connection device according to one embodiment of the invention. The connecting contact 1 is intended for an insert of an electrical plug connector and has an elongated contact element 15 extending in the plugging direction S, which is connected to a busbar 10 for contacting an electrical conductor 5 . On the busbar 10, first and second opposite legs 11 are angled. With the help of the first and second legs for the following reference Figure 1C The described spring element 2 provides a first and a second bearing section 11 . The first and second bearing pins 110 are arranged perpendicularly to the plug-in direc...

Connection device for providing electrical contact between at least one electrical conductor (5) and a busbar (10) of an electrical connecting contact (1), having the features of: a bearing device for at least one spring element (2) being formed on the busbar (10) of the connecting contact (1); the spring element (2) being designed and arranged in an operable manner on the bearing device in such a way that the spring element (2) can be moved from a first tension state to a second and third tension state; wherein in the first tension state of the spring element (2) a contact end (25) of the spring element (2) bears against the busbar (10), and in the second tension state of the spring element (2) the conductor (5) is fixed to the busbar (10) by means of the contact end (25) of the spring element (5) and a contact connection for the conductor (5) to the busbar (10) is closed, and in the third tension state of the spring element (2) the contact connection for the conductor (5) to the busbar (10) is opened. The connection device is provided for a connecting contact (1) of a plug-in connector, wherein the connecting contact can be, in particular, an earthing element (1) of the plug-in connector. A suitable compact spring element (2) with spring travel which is nevertheless suitably long is provided for the connection device.
Description
technical field [0001] The invention relates to a connection device for connecting an electrical conductor to an electrical connection contact and in particular for a protective conductor to a grounding element, in particular a plug connector. The invention also relates in particular to a spring element suitable for the aforementioned connecting device. [0002] In order to connect an electrical line of conductors to an electrical connection contact, spring contact elements are usually provided in such connection devices, which are connected to the electrical connection contact. Depending on the embodiment, different types of spring contact elements are provided for contacting lines or conductors. Expediently, the spring contact element is designed such that the connection to the line or conductor can be disconnected again. [0003] The grounding element of the plug connector connected to the protective conductor is used to keep the accessible parts at ground potential and t...
