Abstract: A plug connector provides an electrical connection to a conductor track connection of a printed circuit board. The plug connector has a first printed circuit board with a conductor track connection and a plugging region for plugging the printed circuit board into the plug connector. The plugging region extends parallel to the first printed circuit board. A contact element and/or a spring element is provided in the plug connector. The plugging region and the contact element and/or the spring element are arranged in such a way that, in a plugged state of the plug connector, the printed circuit board which is plugged into the plugging region is arranged parallel to the printed circuit board and the conductor track connection is arranged opposite the conductor track connection. An electrical connection of the conductor track connection to the conductor track connection is provided by the contact element and/or the spring element.

Abstract: Disclosed is a method and a device for checking the quality of a crimping of a specified cable with a specified contact sleeve using a sensor system for measuring a force and a displacement of a device for the actuation and/or force application of a crimping unit and using an electronic analysis system. In the method a force/displacement curve is detected during the crimping process and is displayed on a screen, wherein the method has the following steps: a stored reference model is displayed on the screen together with the detected force/displacement curve, said reference model having a first and a second envelope curve which define a tolerance range;—comparing the force/displacement curve with the reference model, thereby ascertaining whether the force/displacement curve lies in the tolerance range; and—arriving at a conclusion regarding the quality of the crimping from the comparison.

Abstract: A method for monitoring the state of pressing elements of a crimping device of a crimping apparatus includes: setting of a crimping height: measuring of a travel from a rest position to a working position of the pressing elements, which working position corresponds to the set crimping height: comparing of the travel with a travel from the rest position to a working position of the pressing elements of a setting operation of a crimping height, which setting operation was carried out before the setting operation of the crimping height: recording of data, wherein the recorded data comprises at least one result of the comparison; testing of the comparison for the presence of a predefined criterion; and outputting of a signal if the predefined criterion is satisfied.

Abstract: A locking arrangement for plug connectors, comprising a first locking device and a second locking device. The two locking devices can be plugged together and engaged with one another. At least one blocking element is provided for engaging the first locking device with the second locking device. The blocking element is suitable for mechanical engaging and can be actuated and released via an actuator. In addition, another actuator is arranged in the first locking device or in the second locking device to protect against failure of the locking arrangement. The engaging of the two locking devices can be released by the actuator, even when the actuator fails. The first locking device and the second locking device are provided for use in a plug and a corresponding counter plug.

Abstract: A system is provided comprising of a first plug module and a second plug module, which can be plugged together, wherein the first plug module has a locking arrangement, whereby the plug modules can be reversely locked to each other. The system can be arranged within the housings of industrial plugs and is thus better protected from mechanical loads.
