Definitions
- the invention relates to a coaxial connector for high frequencies, in particular in the millimeter wave range, with a socket part and a plug part and with a resilient electrical contact element which connects the outer conductor of the socket part to the outer conductor of the plug part radially and which is arranged between the plug part and the socket part is.
- a plug connection of the type mentioned is known from DE 38 14 069C.
- the contact element As the contact element, this has a cambered and divided contact spring band which is inserted into an annular groove in the socket part or the plug part.
- the contact spring band should have its radially resilient properties through a
- the bottom surface of the groove follows the bending line of the contact spring strip in the stretched state.
- the contact spring band is divided into spring slats by numerous slits, which are also cambered and are connected to each other at their ends by an edge. However, this connection is not stable at very high frequencies and especially at frequencies above 6 GHz.
- Coaxial MMCX connectors have also become known from DE from j 7b A and US Pat. No. 5,938,465.
- the radial contact elements according to FIGS. 8a and 8b have also become known in the prior art.
- the radial contact element 8a is basket-shaped and largely corresponds to that according to DE 38 14 069 C mentioned above. This contact element, too, cannot guarantee the required stability above about 6 GHz.
- the slotted and resilient outer conductor shown in FIG. 8b also does not meet the requirements mentioned. With these, mechanical stability with respect to the bending moment is therefore insufficient.
- an axial contact element is intended to ensure electrical contact between the plug part and the socket part.
- the wave washer according to FIG. 7a, the slotted disc spring according to FIG. 7b and the multi-stage electroformed part according to FIG. 7c are known in particular. Also not slotted disc springs are known.
- the problem with these axial contact elements is that a comparatively high axial force has to be maintained. This can be easily achieved with screw connections.
- so-called "push-pull" connections of the larger type this can also be achieved by suitable constructive measures.
- connections with a quick-release coupling and a small outside diameter of, for example, 2 mm can hardly constructively support the required axial tension forces reasonable effort can be guaranteed.
- the invention has for its object to provide a connector of the type mentioned, which is stable at very high frequencies and especially at frequencies above 6 GHz.
- the contact element has a plurality of resilient parts, each having a contact point with the outer conductor of the book under radial resilient tension. senteils and form a contact point to the outer conductor of the plug part.
- each spring-elastic part under tension forms a contact point with the outer conductor of the socket part and a contact point with the plug part. Measurements have shown that resonances can be shifted upwards and in particular above 6 GHz, and high stability can thus be achieved.
- An axial contact can be dispensed with, so that a simple and safely operable plug-in coupling can be implemented even with very small dimensions of a few millimeters.
- the plug-in connection according to the invention can also be coupled with the known MMCX connectors.
- the contact points lie in a plane that runs perpendicular to the longitudinal axis of the plug connection and near the front end of the plug part.
- the contact element can be implemented particularly cost-effectively if, according to a development of the invention, it is crown-shaped and in particular has a plurality of axially extending slots which are open on one side. In this case, the contact element can be realized from a corresponding pipe section.
- the resilient parts are tabs, which are each twisted about their longitudinal axis.
- the contact element can also be implemented as a sleeve-shaped part in very small dimensions of a few millimeters.
- the plug connection is stable up to about 65 GHz if, according to a further development of the invention the contact element has more than 6, preferably 8-12 and in particular 10 resilient parts.
- the contact element is preferably mounted in a groove in the socket part.
- the plug part is inserted into the contact element when coupling.
- the resilient parts extend in the axial direction of the insertion direction of the plug part and are stretched radially outwards when the plug part is inserted. Damage to the contact element is avoided even when the two connector parts are plugged together eccentrically.
- FIG. 1 shows a longitudinal section through a connection according to the invention, the individual parts also being shown in a spatial view
- FIG. 2 shows a spatial view of a contact element on a greatly enlarged scale
- FIG. 3 shows a three-dimensional view of the socket part, the individual parts being pulled apart
- FIG. 4 shows a cross section through the connection along the line IV-IV in FIG. 1,
- the coaxial connection 1 shown in FIG. 1 is a plug-in connection, also called a “push-pull” connection, which, in contrast to a screw connection, can be joined without a screwing operation.
- a socket part has a housing part 9, which forms an outer conductor and with a coaxial cable 2
- the coaxial cable 2 has a conventional outer conductor 4, which is conductively connected to the housing part 9.
- An inner conductor 6 is separated from the outer conductor 4 by a dielectric 5 and is electrically connected to a spring bushing 7.
- the spring bushing 7 extends in Longitudinal direction of a stepped bore 20, which has a shoulder 21.
- the socket part B is coupled to a plug part S, which has a housing part 10 with a through hole 22 and which also forms an outer conductor.
- the housing part 10 is connected to a coaxial cable 3, which can be designed like the cable 2.
- a plug pin 8 connects the inner conductor of the cable 3 with the inner conductor of the cable 2.
- the plug pin 8 and the spring bushing 7 can be designed as known per se.
- a circumferential groove 23 is incorporated into the cylindrical outside of the housing part 10, in which a snap ring 19 is mounted, which cooperates with an inclined surface 24 of the housing 9 for axial securing.
- the snap ring 19 is slotted and inserted into the groove 23 so that it is radially compressed when the parts S and B are coupled. If the socket part B and the plug part S are axially plugged together, the snap ring 19 engages in the depression formed by the inclined surface 24 and locks the two parts S and B. in the coupled position shown in Figure 1. An axial tension is generated by the inclined surface 24, which holds the two parts S and B in the position shown against a corresponding separating force. To release the connection, the two parts B and S are pulled apart axially, the snap ring 19 in turn being radially compressed.
- a flat groove 18 which is open on one side is machined into the housing part 9, as can be seen in FIG.
- This groove 18 serves to support a contact element 11 which, according to FIG. 2, forms a closed, crown-shaped sleeve.
- the contact element 11 is made of a conductive material, in particular a spring-elastic metal, and has a circumferential retaining ring 12 which is inserted into the groove 18 according to FIG. 1.
- a plurality and in particular ten tabs 13 are formed on this retaining ring 12, which are each separated from one another by an open slot 14. These tabs 13 are each twisted about their longitudinal axis by a comparatively small angle.
- the tabs 13 each have an end face 15 which lie in a plane which extends perpendicular to the longitudinal direction of the plug connection 1 and which extends directly behind an end face 25 of the housing part 10.
- the tabs 13 are located in an intermediate space 17 which is somewhat wider than the wall thickness of the tabs 13.
- the tabs 13 are twisted such that they each have a contact point to the housing part 9 with an outside corner 16b and an inside point according to FIG Corner 16a form a contact point to the housing part 10.
- Contact element 11 thus forms a plurality of radial and punctiform contact points 16b to the housing part 9 and a plurality of radial and punctiform contact points to the housing part 10, these can be maintained by spring-elastic tensions of the tabs 13 even when the connection 2 is bent or pulled on the two parts B and S. Due to the tensions of the tabs 13, tolerance deviations in the width of the intermediate space 17 can also be accommodated.
- the two housing parts 9 and 10 are preferably not slotted and thus closed, as a result of which a particularly high bending moment can be absorbed.
- the slots 14 are open on one side and have a comparatively short length, in particular this length is less than 1.7 mm, preferably 1.1 mm.
- the flaps 13 are therefore comparatively sensitive parts which must not be injured when coupling. Since the plug part S or the housing part 10 is pushed into the contact element 11 in the direction of extension of the tabs 13, the tabs 13 cannot be injured even when the two parts B and S are eccentrically plugged together. Damage to the tabs 13 is largely excluded even when loosening.
- FIGS. 5 and 6 have shown stability up to 65 GHz.
- a connection according to the invention was measured, each with 13 cm long “semi-rigid” cables 2 and 3, which were each soldered to the socket part B or plug part S.
- the two cables 2 and 3 were screwed to the measuring station The measurement was carried out using a vector network analyzer.
- the return loss (Sll forward reflection) was measured on the one hand according to FIG. 5 and the insertion loss (S21 forward transmission) according to FIG. 6 on the other hand. Measurements were made in the frequency range from 0.13 to 65 GHz. On the joint was bent and pulled during the measurements. The return loss is the logarithmic ratio of the reflected power to the input power in dB. A reflection-free line has an RL of minus infinity dB, on the other hand a short circuit of 0 dB. The insertion loss is the logarithmic ratio of the transmitted power to the input power in dB. A lossless line has an insertion loss of 0 dB and a short-circuited line of minus infinite dB. In the measurements according to FIGS. 5 and 6, only the amplitude was shown. The measurements in particular show that at a frequency lower than 65 GHz, there are no significant and disruptive reflections even when bending and pulling on the connecting parts or on the cables.
