Patent number: 11404824Abstract: Plug connections and in particular plug connections for use in an industrial environment are presented. An attachment housing arrangement has an attachment housing for accommodating a hood of a plug connector with plug contacts and a mechanical locking arrangement for mechanically locking the hood on the attachment housing. Also presented is a method for unlocking a mechanical locking of a hood of a plug connector with plug contacts on an attachment housing of an attachment housing arrangement. The attachment housing arrangement is provided with a fixing arrangement for fixing the mechanical locking arrangement at least in a locking state, and with a control unit for controlling the fixing arrangement, the control unit being configured to control the fixing arrangement so as to release a fixing of the locking arrangement only when the plug contacts are free of current and free of voltage within predefined tolerances.Type: GrantFiled: April 16, 2018Date of Patent: August 2, 2022Assignee: HARTING Electric Stiftung & Co.

Patent number: 11336055Abstract: An electrical connector housing is provided with at least one locking clip, which is mounted pivotably via a bearing pin and has a locking region and an actuation region. In order to reversibly lock the electrical connector housing to a mating electrical connector housing, the locking region engages overbearing journals integrally moulded on the mating electrical connector housing. The locking clip has a locking device or means for blocking the pivot movement of the locking clip. In this manner, an accidental release of the plug-in connection can be prevented.Type: GrantFiled: October 24, 2018Date of Patent: May 17, 2022Assignee: Harting Electric GmbH & Co. KGInventor: Norbert Kropiewnicki

Patent number: 11276967Abstract: Disclosed a device for the load-free disconnection of a plug-in connection, which has an electrical disconnecting device and a locking clip. The locking clip can be pivoted both into a position locking the plug-in connection and into a position unlocking the plug-in connection. The device also has a sensor system, which interacts with the locking clip in its locking position to detect the locked state, in order to control the electrical disconnecting device.Type: GrantFiled: April 8, 2019Date of Patent: March 15, 2022Inventor: Norbert Kropiewnicki

Patent number: 11201441Abstract: A plug-in connector with a plug side and a connector side is provided, the plug-in connector comprising a housing, a frame, and at least one contact insert. The contact insert comprises sensors and a circuit board with electronics. According to prior art, the risk of overheating of the electronics, occurring inside the plug-in connector as a result of power dissipation, is a reason for the failure of plug-in connectors known to date. Embodiments described herein ensure heat dissipation via a cooling element so that overheating is prevented.Type: GrantFiled: August 15, 2017Date of Patent: December 14, 2021Assignee: HARTING Electric GmbH & Co.

Patent number: 10535960Abstract: A system comprises a first plug connector module and a second plug connector module. The plug connector modules each have at least two contact elements. The first plug connector module has at least one spring link. In the unplugged state, the at least one spring link connects the at least two contact elements of the first plug connector module electrically conductively to each other. A method for plugging a first plug connector module with a second plug connector module is based on the first and the second plug connector modules being guided toward each other in the plug-in direction. A sliding element of the second plug connector module presses against at least one spring link of the first plug connector module and, as a result, the at least one spring link is brought out of touching contact with at least two associated socket contacts.Type: GrantFiled: February 14, 2018Date of Patent: January 14, 2020Assignee: HARTING Electric GmbH & Co.
