Abstract: A method for adjusting an electrical length of a coaxial cable and a plug connector with an adjustable length that facilitates the adjustment of the electrical length of the cable are disclosed. With the method, both ends of the coaxial cable are terminated with a respective coaxial plug connector wherein at least one of the plug connectors has an adjustable length. One of the coaxial plug connectors is connected with a phase measurement device, and the other coaxial plug connector having the adjustable length is electrically shorted with a short-circuit plug. A pressing force is applied in an axial direction between the short-circuit plug and an outer conductor of the coaxial plug connector, until the phase measurement device indicates that the electrical length has reached a predetermined value.

Abstract: A coaxial plug connector with an adjustable length is disclosed that can be used for adjusting the phase of a coaxial cable. The outer conductor of the coaxial plug connector is on the connection side received in the outer conductor of the coaxial plug connector on the cable-side by a press fit. The inner conductor of the plug connector can be displaced in an insulator support member by at least the adjustment distance of the outer conductor of the connector on the connection side.

Abstract: The invention relates to a heat exchanger for motor vehicles, having a large number of flat tubes through which a liquid cooling medium can flow, and having corrugated fins which are associated with these flat tubes and to which environmental air or other media can be applied. The flat tubes having indentations pointing inward on at least one of their flat faces. Heat transfer between the core flow of the cooling medium and the flat tube walls is improved, and the power density of the heat exchanger is thus increased. The indentations are in the form of elongated vortex generators having a longitudinal axis, and the ratio between the height (H) of the vortex generators and the height (h) of the flat tubes is preferably approximately 0.05 to 0.
