Description

Background of the invention

The present invention relates to a connection device for producing an electrically conductive connection between an electrical conductor and a technical device.

From the prior art connecting devices of the aforementioned type are known, which have a clamping pin and a connection element or contact element with a sleeve-like body. To the contact element, the electrical conductor is connectable and the sleeve-like body is in a bore or cylindrical receptacle of the respective technical device, such. a cabinet door to be grounded, can be used.

To connect the connecting device with the technical device of the sleeve-like body is clamped after insertion into the bore by inserting the clamping pin in the sleeve-like body with the inner surface of the bore or radially clamped.

A connecting device with such a sleeve-like body and such a clamping pin is from the DE 20 2009 006 254 U1 known. To produce the electrically conductive connection between the electrical conductor and the technical device of the clamping pin is quite expensive, usually by means of a gripping tool to introduce into the sleeve-like body.

Underlying task

It is an object of the invention to provide a connecting device of the type mentioned above with a clamping pin and a sleeve-like body in which the clamping pin in the sleeve-like body in a simple and practical manner in the provided for producing the clamping connection with the technical device clamping position is movable.

This object is achieved with a connecting device having the features of independent claim 1.

The connecting device for producing an electrically conductive connection between an electrical conductor and a technical device is characterized in particular in that the connecting device has a pivoting element or a pivoting device with which or with which the clamping pin can be contacted by a pivoting movement and moved into the clamping position is or with which the clamping pin contacted by pivoting and movable into the clamping position.

By providing the pivoting element, the clamping pin - which is movably received in the sleeve-like body and which is longitudinally movably received in the sleeve-like body - can advantageously be moved by a simply vornehmbare pivotal movement of the pivot member in the clamping position, in which a clamping pin section the spring arm - or the spring arms - presses against the inner surface of the cylindrical receptacle or in which a clamping pin section presses the spring arm or the spring arms to form an elastic deformation or an elastic bending of the spring arm or the spring arms to the inner surface of the cylindrical receptacle, namely for clamping holding the sleeve-like body in the cylindrical receptacle of the technical device or for clamping the sleeve-like body with the inner surface of the cylindrical receptacle when the sleeve-like body eingese in the cylindrical receptacle of the technical device is protected or when the sleeve-like body is inserted into the cylindrical receptacle of the technical device at least partially or entirely. The clamping pin is thus movable by the pivoting element in a simple and practical manner in the provided for producing the clamping connection with the technical device clamping position. Unlike the one from the DE 20 2009 006 254 U1 known solution can therefore be advantageous for producing the electrically conductive connection between the electrical conductor and the technical device apart from introducing the clamping pin consuming means of a gripping tool in the sleeve-like body. In particular, unlike that from the DE 20 2009 006 254 U1 known device of the clamping pin is already in the sleeve-like body movably or longitudinally movably received and does not need to be introduced consuming in this, as in the case of the DE 20 2009 006 254 U1 known device is the case.

It is understood that the term "sleeve-like body" is to be understood as meaning a body which is designed in the form of a sleeve or essentially or approximately in the form of a sleeve or which is designed in the form of a hollow body or elongated hollow body or is formed approximately or substantially in the form of a hollow body or elongated hollow body.

Of course, the slots do not have to extend over the entire sleeve-like body. Each of the slots can also extend only from the inlet opening or the end of the sleeve-like body to a section or longitudinal section of the sleeve-like body which is at a distance from the inlet opening. In particular, each of the slots may particularly preferably extend in the axial direction or substantially in the axial direction of the sleeve-like body or parallel to the longitudinal axis of the sleeve-like body or substantially parallel to the longitudinal axis of the sleeve-like body.
