DESCRIPTION OF EMBODIMENT EXAMPLES

(14) The electrical plug connector 1 exhibits an inner-conductor contact element 2, which is arranged in a through-bore 3 of an insulator element 4, and an outer-conductor contact element 5, in the central recess 6 of which the insulator element 4 is arranged.

(15) At the distal end 7 of the inner-conductor contact element 2that is to say, at an end of the inner-conductor contact element 2 pointing toward the mating plug connector 15several spring lugs 8, preferentially two spring lugs 8, have been formed for electrical and mechanical contacting of a preferentially pin-shaped inner-conductor contact element 16 of the mating plug connector 15.

(16) In the distal end region 9 of the outer-conductor contact element 5that is to say, at an end of the outer-conductor contact element 5 pointing toward the mating plug connector 15likewise several spring lugs 10 have been formed for electrical contacting of a preferentially socket-shaped outer conductor 14 of the mating plug connector 15. The individual spring lugs 10 of the outer-conductor contact element 5 have preferentially been arranged in equidistant angular sections on the periphery of the outer-conductor contact element 5. The spring lugs 10 may each have been fastened to the outer-conductor contact element 5 on one side by one end, or fastened to the outer-conductor contact element 5 on two sides by two ends in each instance.

(17) A lateral extension 12 has been formed on the external generated surface 11 of the sleeve-shaped insulator element 4. The lateral extension 12 of the insulator element 4 has preferentially been formed in an axial longitudinal section of the insulator element 4 that preferentially corresponds to the axial longitudinal section in which the spring lugs 10 on the outer-conductor contact element 5 have also been formed. The insulator element 4 consequently has a larger lateral dimension in the region of the lateral extension 12 than in the remaining axial sections of the insulator element 5.

(18) In the first manifestation of the electrical plug connector 1 according to FIGS. 1A, 1B, 1C and 1D, the lateral extension 12 of the insulator element 4 has been shaped in the form of a cylinder. The cylindrical lateral extension 12 of the insulator element 4 may extend along an axial portion of the spring lugs 10 of the outer-conductor contact element 5 or, as represented in FIG. 1A, along the entire axial longitudinal extent of the spring lugs 10 of the outer-conductor contact element 5 or even beyond the entire axial longitudinal extent of the spring lugs 10 of the outer-conductor contact element 5.

(19) As can be clearly and unambiguously discerned from FIGS. 1A and 1B, the longitudinal axis L.sub.I of the insulator element 5 has been arranged in axially offset manner relative to the longitudinal axis L.sub.AL of the outer-conductor contact element 5 in the non-plugged state of the plug connector 1, and consequently the insulator element 5 has not been arranged centrically relative to the outer-conductor contact element 5. In particular from the cross-sectional representation shown in FIG. 1B, it can be discerned that in this eccentric position only a subset of the spring lugs 10 of the outer-conductor contact element 5 is in contact with the external generated surface 11 of the insulator element 4, whereas the other subset of the spring lugs 10 of the outer-conductor contact element 5 has been arranged spaced from the external generated surface 11 of the insulator element 4.

(20) In the plugged state of the plug connection 13 according to FIGS. 1C and 1D, the sleeve-shaped outer conductor 14 of the mating plug connector 15 contacts all the spring lugs 10 of the outer-conductor contact element 5 of the plug connector 1 on the inside, and the spring lugs 8 of the inner-conductor contact element 2 of the plug connector 1 contact the pin-shaped inner-conductor contact element 16 of the mating plug connector 15 on the inside, electrically in each instance. The spring lugs 10 of the outer-conductor contact element 5 pertaining to the plug connector 1 are bent laterally inward during the plug-in procedure by the sleeve-shaped outer conductor 14 of the mating plug connector 15 in such a manner that the mechanical contact region 18, formed in each instance on the internal surface 17 of each spring lug 10, contacts an associated mechanical contact region 19 on the lateral extension 12 of the insulator element 4.

(21) In this way, the insulator element 4 is moved out of its originally eccentric position relative to the outer-conductor contact element 5 in the non-plugged state of the plug connector 1 into a centric position relative to the outer-conductor contact element 5 in the plugged state of the plug connector 1. As is evident from FIGS. 1C and 1D, in the plugged state of the plug connector 1 the longitudinal axis L.sub.I of the insulator element 4 and the longitudinal axis L.sub.AL of the outer-conductor contact element 5 come to coincide. The insulator element 4 is clamped into the centric position relative to the outer-conductor contact element 5 by the spring lugs 10 of the outer-conductor contact element 5. The outside diameter of the lateral extension 12 of the insulator element 4in particular, the mechanical contact region 19 on the lateral extension 12 of the insulator element 4has been designed in such a way in combination with the inside diameters of the associated mechanical contact regions 18 on the internal surfaces 17 of all the spring lugs 10 of the outer-conductor contact element 5 that, in the plugged state, the contact region 18 on the internal surface 17 of each spring lug 10 contacts in each instance the associated mechanical contact region 19 on the lateral extension 12 of the insulator element 4.

(22) In a second manifestation of a plug connector 1 according to FIGS. 2A, 2B, 2C and 2D, the lateral extension 12 on the external generated surface 11 of the insulator element 4 in the axial region of the spring lugs 10 of the outer-conductor contact element 5 is bead-shaped or ring-shaped. The bead-shaped or ring-shaped lateral extension 12 on the external generated surface 11 of the insulator element 4 preferentially has a smaller axial dimension than a cylindrical lateral extension 12. The contacting between the mechanical contact region 18 on the bead-shaped or ring-shaped lateral extension 12 of the insulator element 4 and the associated mechanical contact region 19 on the internal surface 17 of the spring lugs 10 of the outer-conductor contact element 5 is consequently reduced, preferentially to a linear or punctiform contacting. The contact pressure and therefore the press-in pressure between the spring lugs 10 of the outer-conductor contact element 5 and the insulator element 4 consequently increases. Given the same insertion force, a more efficient centering of the insulator element 4 by the spring lugs 10 of the outer-conductor contact element 5 is possible, particularly in the case of an insulator element 4 that is difficult to move or difficult to tilt.

(23) With increased contact pressure or press-in pressure, a lateral compression of the bead-shaped or ring-shaped lateral extension 12 on the external generated surface 11 of the insulator element 4 is consequently preferentially possible, as represented in FIGS. 2C and 2D. For the purpose of illustrating the lateral compression, the dashed contour of a laterally non-compressed bead-shaped or ring-shaped lateral extension 12 on the external generated surface 11 of the insulator element 4 is represented in FIG. 2C.

(24) Whereas in the second manifestation of the plug connector 1 according to FIGS. 2A, 2B, 2C and 2D the lateral extension 12 of the insulator element 4 has been formed in one piece with the remaining insulator element 4, in the third manifestation of a plug connector 1 according to FIGS. 3A, 3B, 3C and 3D the lateral extension 12 takes the form of a separate component which has been guided over the external generated surface 11 of the insulator element 4 and connected to the insulator element 4, preferentially by force closure via a press fit or by material closure via, for instance, an adhesive bond. The lateral extension 12 of the insulator element 4, which takes the form of a separate component, has preferentially been produced from a dielectric material and consequently constitutes an integral part of the dielectric of the coaxial plug connector 1. Alternatively, the separate component may also have been produced from a metallic material and may consequently constitute an integral part of the outer-conductor contact element 5.

(25) In a fourth manifestation of the plug connector 1 according to FIGS. 4A, 4B, 4C and 4D, a lateral extension 25 which is directed laterally inward has been formed in each instance on the internal surface 11 of each spring lug 10 of the outer-conductor contact element 5. The lateral extension 25 on each spring lug 10 has preferentially been shaped in the form of a bead. The lateral extension 25 on the internal surface 11 of each spring lug 10 has been designed in each instance in such a way that in the plugged state of the plug connection 13 the mechanical contact region 18, formed in each instance on the lateral extension 25 of each spring lug 10, contacts an associated mechanical contact region 19 on the external generated surface 11 of the insulator element 4. Since the lateral extension 25 on each spring lug 10 represents in each instance a capacitive point of perturbation in the impedance curve of the coaxial plug connector 1, a corresponding inductive compensation should preferentially be formed in a different axial section of the plug connector 1.

(26) In a fifth manifestation of a plug connector 1 according to FIGS. 5A and 5B, in the plugged state of the plug connector an insulator 20 of the mating plug connector 15in particular, the sleeve-shaped end region 21 of the insulator 20 of the mating plug connector 15has been inserted between the outer-conductor contact element 5 and the insulator element 4 of the plug connector 1. In this case, the insulator element 4 of the plug connector 1 and the insulator 20 of the mating plug connector 15in particular, the sleeve-shaped end region 21 of the insulator 20 of the mating plug connector 15have been arranged without play relative to one anotherthat is to say, the insulator element 4 of the plug connector 1 and the insulator 20 of the mating plug connector 15 have been guided relative to one another during the plug-in procedure.

(27) In addition, all the spring lugs 10 of the outer-conductor contact element 5 have been bent laterally inward by the sleeve-shaped outer conductor 14 of the mating plug connector 15 in the plugged state of the plug connection 13 and have each been set up to clamp centrically the insulator 20, inserted between the outer-conductor contact element 5 and the insulator element 4 of the plug connector 1, of the mating plug connector 15. For this purpose, the mechanical contact region 18 on the internal surface of each spring lug 10 and a mechanical contact region 22 on the external generated surface of the insulator 20 of the mating plug connector 15 should be shaped in such a manner that a contacting, or a centric clamping, can occur.

(28) Although the present invention has been described fully in the foregoing with reference to preferred embodiment examples, it is not restricted thereto but capable of being modified in diverse ways.
