Definitions

• the invention relates to a coaxial connector, in particular for printed circuit boards, according to the preamble of claim 1.
• At least one outer conductor socket with an associated inner conductor is usually fixed on each printed circuit board.
• the inner conductor has a normally cylindrical contact pin, which can be inserted in a resiliently clamping manner into a correspondingly designed front recess in the inner conductor part of an adapter in the form of a sleeve-shaped plug-in coupling.
• the design is such that a defined air gap is left between the outer conductor bushing and the end face of the plug-in coupling.
• the invention is therefore based on the problem of designing the coaxial connector of the generic type in order to eliminate the disadvantages described in such a way that its repeatability, particularly at high transmission frequencies up to 60 GHz and more, is decisively improved and at the same time with significantly simplified production while avoiding undesirable jumps in diameter of the contact pin a consistently good contact zone is guaranteed.
• the configuration is such that the inner conductor of the circuit board is designed as a spring plate, which is fixed at one end to the circuit board or to an insulation and at its other free end to the inner conductor part of the plug-in coupling designed as a contact pin can be brought into engagement.
• the spring plate is designed in the manner of a tab or strip, which ensures simple manufacture. Always good contact between the inner conductor of the printed circuit board and the inner conductor part of the plug-in coupling designed as a contact pin is ensured if — as is also provided according to the invention — the spring plate is fixed under pretension.
• the free end of the spring plate expediently protrudes into the axis of the contact pin of the plug-in coupling. For this reason, no special measures have to be taken to always ensure contact between the spring plate of the printed circuit board and the contact pin of the plug-in coupling.
• the free end of the spring plate is usually in contact with the respective end of the contact pin by means of point contact. It is within the scope of the invention to provide an opening at the free end of the spring plate which is largely aligned with the axis of the contact pin. This then results in a linear, usually circular, contact between the spring plate and the contact pin.
• the contact pin of the plug coupling has rounded or spherical, in particular hemispherical, ends.
• Such a contact pin can be produced with the least possible manufacturing effort and at the same time ensures that the contact between its ends and the respective free end of the spring plate is always achieved with the highest efficiency.
• the contact pin expediently has such a length that, when the plug-in coupling is inserted into the socket-shaped outer conductor of the printed circuit board, it resiliently engages with the free end of the spring plate at its respective free end.
• the flexibility of the contact between the spring plate and the contact pin is decisively further improved if, as provided according to the invention, the contact pin is axially displaceable in the plug-in coupling or within its insulation. tion is arranged. This enables, as it were, a constant centering of the contact between the contact pin and the spring plate, since depending on the axial load from one side or the other, the contact pin is able to shift accordingly within its plug-in coupling. In this way, the contact between the spring plate and the end of the contact pin is always guaranteed and with full effectiveness.
• the formation of the coaxial connector according to the invention can be realized with considerably reduced manufacturing costs.
• it offers the decisive advantage that when the possible relative movements mentioned occur between the printed circuit boards in the direction of the longitudinal axis of the contact pin and / or transversely thereto, a consistently good contact zone is always ensured. This is based on the fact that, due to the above-mentioned configuration of the contact between the spring plate and the contact pin, the desired contact zone is always maintained even when the contact pin is tilted and / or moved longitudinally.
• Fig. 1 shows a preferred embodiment of the coaxial connector according to the invention in cross section
• Fig. 2 shows a modified embodiment in detail.
• the coaxial connector shown in FIG. 1 of the drawing serves to connect two printed circuit boards 1, 2, which is also known as a board-to-board connection.
• an outer conductor 3 in the form of an outer conductor socket and an inner conductor 4 are fixed on each printed circuit board 1 or 2.
• the inner conductor 4 is insulated from the outer conductor socket 3 by means of an insulating part 5.
• the circuit boards 1, 2 can be electrically connected by means of an adapter 6, this adapter 6 being in the form of a sleeve-shaped plug-in coupling.
• the plug-in coupling 6 has on its outside a sleeve-shaped outer conductor part 7, which can be brought into engagement in the manner shown at its front ends by means of a circumferential annular bead 8 with the respective outer conductor socket 3 of the printed circuit boards 1 or 2.
• the plug-in coupling 6 also has - in relation to its sleeve-shaped outer conductor part 7 with the interposition of insulation 9 - an inner conductor part 10 which runs axially in the center within the plug-in coupling 6 and is designed as a contact pin.
• This contact pin 10 is such that it is hemispherical at its two ends 11 and protrudes from the plug-in coupling 6 with these hemispherical ends in the manner shown.
• the contact pin 10 is arranged axially displaceably within the insulation 9.
• the respective inner conductor 4 of the printed circuit boards 1 or 2 is designed as a strip-shaped spring plate, which is fixed with one end under pretension to the printed circuit board 1 or 2 or to the insulation 5 and with its free end 13 at an angle in the longitudinal central axis 12 of the coaxial connector or beyond.
• the free end 13 of the spring plate 4 has an opening 14 which is largely aligned with the axis 12 of the contact pin 10.
• a more or less circular contact between the edges of the opening 14 is achieved of the spring plate 4 and the rounded end 11 of the contact pin 10 achieved.
• the flexibility of the contacting and its centering is always guaranteed, which is based on the one hand on the basic arrangement of the spring plate 4 and on the other hand on the axial displaceability of the contact pin 10.
