  • Patent number: 11984686
    Abstract: A high frequency (HF) terminal for an HF connector includes an electromechanical contact section, a mechanical fastening section, an electromechanical connection section, and an HF compensation region apart from the electromechanical contact section. The HF compensation region is geometrically developed in such a way that a loss in a signal integrity of an HF plug-in connector including the HF connector with the HF terminal and an HF mating connector with an HF mating terminal in a final plugged-in position can be at least partially compensated by the HF compensation region.

  • Patent number: 11837803
    Abstract: A chiclet for a chiclet connector includes a conductor having a first end and a second end. A housing of the chiclet encloses and defines a housing interior. The conductor extends through the housing interior with the first and second ends of the conductor forming contacts projecting from the housing. The housing forms an electromagnetic shield electrically insulated from the conductor. A support of the chiclet corresponds in shape to the housing interior and is connected to the conductor for fixing the conductor within the housing.

  • Patent number: 11486907
    Abstract: A monitoring device for monitoring an impedance of a protective conductor. The monitoring device has a first voltage divider for connection to a voltage source including a series connection to a first resistor and a second resistor. The second resistor has a resistance value which corresponds to a threshold value for the impedance of the protective conductor. A second voltage divider includes a series connection to a third resistor and a bridge diode and a connection to the first resistor at a first end of the third resistor and connectable to a second end of the third resistor and to the protective conductor. A measuring device is provided for the detection of a bridge voltage between a first node and a second node if the impedance of the protective conductor is greater than the value of the second resistor.

  • Publication number: 20220250548
    Abstract: A connection device for an appliance with an appliance housing includes a main body having an appliance-side end, a connection-side end facing away from the appliance-side end, and a conduit extending from the appliance-side end to the connection-side end, a securing element securing the main body to a wall section of the appliance housing, and a conductor leading through the main body from the connection-side end to the appliance-side end. The main body has a first abutment surface facing the appliance-side end. The securing element has a second abutment surface facing the first abutment surface. The first abutment surface and the second abutment surface enclose therebetween a receiving region for clamping reception of the wall section of the appliance housing.

  • Patent number: 9515422
    Abstract: The present invention relates to an electrical connector having an electrically insulating contact carrier and at least one electrically conductive contact element which is provided with an impedance equalization element. In particular, the present invention relates to an electrical connector which has defined impedance properties, both with and without shielding. In order to adjust the impedance of the connector (100) in at least a portion of the region in which the at least one contact element (104) is arranged, at least one impedance equalization element (112) is provided on the contact carrier (102) and integrated therewith, wherein the impedance equalization element (112) has an electrically conductive, substantially planar structure, which is arranged with respect to the at least one contact element (104) with a predetermined spacing which is dependent on the impedance value to be adjusted.

  • Patent number: 8777640
    Abstract: The present invention relates to an electrical connector with an electrically insulating contact carrier and with at least one electrically conducting contact element which is held in the contact carrier. Furthermore, the present invention relates to a manufacturing method for manufacturing a connector of this type. Changes in dimension in the geometry of the contact carrier and also fluctuations in spacing and geometry in the enclosing shielding cause impedance inhomogeneities in the signal propagation direction that adversely influence the signal quality. Furthermore, it may be necessary to purposefully set the impedance so as to differ from the nominal impedance.
