  • the outer and inner conductor contact elements of the electrical plug connector and of the electrical mating connector must each be arranged sufficiently centrally to one another.
  • the outer conductor contact element must be arranged centered on the two inner conductor contact elements. For this purpose, the point of intersection of the two axes of the outer conductor contact element is to be arranged in the center of the distance between the two inner conductor contact elements, which forms the center of the differential connector.
  • the lack of centricity between the outer and the inner conductor contact element or. the inner conductor contact element pair results from an axial offset between the outer and the inner conductor contact element or. the inner conductor contact element pair, an angular offset of the insulator element in the outer conductor contact element and / or an angular offset of the inner conductor contact element or. of the inner conductor contact element pair in the insulator element.
  • the present invention has the object of centering between the outer and inner conductor contact elements of an electrical connector, preferably a coaxial electrical connector, to realize even in the event that the individual components of the electrical connector in their Manufacturing or in their assembly, for example, the above inaccuracies or. are subject to error.
  • An electrical connector for electrical and mechanical connection to an electrical mating connector having an insulator element and an outer conductor contact element, which at least partially encloses the insulator element, spring tabs for electrically contacting a corresponding outer conductor of the mating connector (in particular a corresponding outer conductor contact element of the mating connector) being formed in the outer conductor contact element, wherein in an unplugged state of the plug connector with the mating connector at least one spring clip is spaced apart from the insulator element (i.e.
  • the insulator element can have freedom of movement with respect to the outer conductor contact element), the insulator element and at least a subset of the spring clips being set up (in particular each formed and / or are arranged to each other) that in a partially mated state or in a mated state of the connector with the mating connector (i.e. H . during and/or after a plugging process of the connector with the mating connector) the insulator element is clamped directly or at least indirectly centered by at least a subset of the spring shackles by a first element of the mating connector applied to the outer conductor contact element (preferably directly, but possibly also only indirectly).

  • the two lateral extensions are each formed in an axial section of the insulator element which is axially opposite to the rigid section of the inner conductor contact element and is thus spaced axially from the distal end section of the inner conductor contact element with its spring tabs.
  • the lateral extent of the lateral expansions on the inner lateral surface of the insulator element is preferably in each case a multiple, preferably by a factor of two to 15, particularly preferably by a factor of four formed to ten, smaller than the lateral dimensions of the lateral extension on the outer surface of the insulator element.
  • two lateral extensions formed axially offset on the outer lateral surface of the inner conductor contact element are also conceivable for centering the inner conductor contact element with respect to the insulator element. Since the two lateral extensions on the outer lateral surface of the inner conductor contact element each represent capacitive imperfections in the impedance curve of the connector, these are possibly compensated by correspondingly inductively designed compensations to compensate within the longitudinal extension of the connector, if necessary.

  • the lateral extension 12 of the insulator element 4 is formed in one piece with the rest of the insulator element 4, in the third embodiment of a connector 1 according to Figures 3A, 3B, 3C 3D the lateral expansion 12 is designed as a separate component which is guided over the outer lateral surface 11 of the insulator element 4 and is connected to the insulator element 4 preferably non-positively via a press fit or cohesively via an adhesive bond, for example.
  • the lateral expansion 12 of the insulator element 4 embodied as a separate component is preferably made of a dielectric material and thus forms part of the dielectric of the coaxial plug connector 1 .

Since the lateral widening 25 on each spring clip 10 represents a capacitive point of disturbance in the impedance profile of the coaxial connector 1 , a corresponding inductive compensation should preferably be implemented in another axial section of the connector 1 .

  • the mechanical contact areas 18 on the two lateral extensions 12 of the insulator element 4 are designed in such a way that they contact the outer lateral surface 26 of the inner conductor contact element 2 .
  • the mechanical contact areas 18 on the two lateral extensions 12 each have an equally large lateral extension, which is dimensioned such that the inner conductor contact element 2 is centered with its longitudinal axis LIL to the insulator element 4 with its longitudinal axis Li.

Des pattes de ressort (10) destinées à entrer en contact avec un conducteur externe (14) correspondant du connecteur de fiche (15) correspondant sont formées dans l'élément de contact de conducteur externe (5). Lorsque le connecteur de fiche (1) n'est pas enfiché avec le connecteur de fiche (15) correspondant, au moins une patte ressort (10) est espacée de l'élément isolant (4). Lorsque le connecteur de fiche (1) est partiellement enfiché ou enfiché conjointement avec le connecteur de fiche (15) correspondant, l'élément d'isolation (4) est serré de manière centrée par au moins un sous-ensemble des pattes de ressort (10) grâce à un premier élément (14) du connecteur de fiche correspondant, ledit premier élément étant appliqué à l'élément de contact conducteur externe (5).
