Definitions
- the invention relates to an RF connector with a plug head and with a socket on its plug-side End of a concentric recess with an inner wall Has annular surface.
- RF connectors of this design called RF contacts increasingly also be used in mobile phones, are often known and therefore require no further explanation.
- the present invention is therefore based on the object specify an RF connector, the best possible ensures electrical contact between plug head and socket.
- an RF connector of the aforementioned Species provided, in which in the inner-walled annular surface the sleeve provided at least one annular recess is, clamped in the respective one conductive spring ring in such a way is that the plug head under electrical contact of the spring ring radially from the outside into the concentric recess the socket is inserted.
- a Pinched spring ring In a recess incorporated in the socket is a Pinched spring ring.
- Essential to the invention here is that the spring ring at least partially over the inner-walled annular surface the socket in the recess provided for the plug head recess protrudes, so that the plug head clasps into the socket, if it is inserted from the outside into the socket.
- the inventive Plug connection is based on the knowledge that when inserting the plug head into the socket of the plug head the elastic spring ring aside pushes, causing this in the leadership of the annular recess is pressed. In this way, a defined electrical contact and thus a low contact resistance the spring ring ensures the plug head and the socket become. In particular, the requirement of a good electrical contact even with a long life the RF contact still be guaranteed.
- the spring ring not firmly connected to the jack, but again is removable from the socket. This must be at an RF contact wear with a broken or frequent opening Spring ring only this spring ring and not the entire Replace the socket.
- a typical RF connector contains a plug head, the a cylindrical outer conductor contact sleeve for contacting an outer conductor of a coaxial cable and an inside arranged the outer conductor and through a dielectric from this separate inner conductor.
- the outer conductor contact sleeve in the area concentric recess has a cylindrical shape.
- any other shape, such as a conical, frustoconical or similar shape conceivable.
- a significant improvement in the contact can thereby be achieved that the contacting the socket and the plug Spring ring has a continuous slot.
- This slot is the elasticity of the spring ring and thus significantly improved the electrical contact.
- Preferably is the slot at one of the corners of the spring ring arranged.
- the Diameter of the annular recess is slightly larger than the cross section of the spring ring.
- the spring ring is triangular educated.
- the triangular spring ring contacted at its corners, the annular recess of the socket and at its chords the cylindrical outer conductor contact sleeve of the plug head. Through these three contact surfaces to the socket or the plug head is a very good contact reliability guaranteed.
- the spring washer a square, pentagonal, hexagonal, etc. shape having. Especially when using such polygonal Circlips could be due to the larger number of contact surfaces compared to triangular spring washers the increase the entire contact surface and thus the electrical contact even better. It would also be possible Slotted spring washers on one side.
- the spring ring consists of wire-shaped material.
- this wire-shaped Spring ring consists at least partially of spring steel, spring steel is typically over a very long period of time maintains the desired elasticity and beyond a has very good electrical conductivity.
- a further improvement of the electrical contact allows through an annular detent groove, which is in the outer wall the outer conductor contact sleeve of the plug head incorporated is, achieve. If the plug head is inserted into the socket, then clip the spring ring into this Einrastrille. Such Einrastrille proves to be very useful, As a result, the plug is not accidentally, for example through vibrations or a slight pulling movement, again can solve the jack and the RF contact unintentionally is interrupted. To the clipped spring ring again from the snap-in groove, it is then necessary a certain tensile force on the plug head against the Exercise insertion direction.
- a best possible electrical contact is obtained further, if the diameter of the Einrastrille and the diameter the wire of the spring ring chosen approximately equal are. In this case, the common surface of Einrastrille and wire at the greatest, creating an optimal electrical Contact can be achieved.
- the diameter of the wire of the spring ring and the height of the annular recess approximately are the same size. This ensures that that of the spring ring in the leadership of the annular recess has almost no play and thus a stable RF contact is created.
- FIG. 1 shows a longitudinal section of an HF plug connection according to the invention 1, a socket 2 and one in the socket 2 inserted plug head 3 has.
- the plug head 3 consists here of an outer conductor contact sleeve 4 and a plug core 5.
- the plug core 5 includes a not shown in Figure 1 by a dielectric of the Outer conductor contact sleeve 4 separate inner conductor. Further has the plug head 3 a Einrastrille 6, whose function Explained in detail below with reference to FIG 2 becomes. So that the plug head 3 better inserted into the socket 2 can be, is an insertion phase 7 on the socket side End of the plug head 3 is provided.
- the socket 2 has opposite to the plug head 3 Side a flange 8, over which the socket 2, for example be connected to a housing of an RF device can. Furthermore, the socket 2 a bushing core 9, in one separated from the female shell 10 by a dielectric Inner conductor is provided (not shown in Figure 1). In the plug-side end of the socket 2 is a to the bushing core 9 concentric recess 11 provided in the plug head 3 is almost flush plugged. By this concentric recess 11 is defined an inner wall, from a plug-in direction I of the plug head 3 located end face 12 and one arranged laterally thereto Ring surface 13 is made.
- annular recess 14 In the annular surface 13, an annular recess 14 is provided, in which a spring ring 15 is inserted. It is In this case, make sure that the annular recess 14th and the spring ring 15 disposed therein and the Einrastrille 6 is at inserted plug head 3 substantially in a level and the plug head 3 while possible not the end face 12 of the concentric recess 14 contacted.
- FIG. 2 shows a cross section of the HF plug connection according to the invention according to Figure 1 in the plane of the spring ring 15.
- the spring ring 15 in Figure 2 has the shape of a triangle, wherein a slot 16 at one of the corners 17 of the triangular Spring ring 15 is provided.
- the thus formed triangular Spring ring 15 contacted at the corners 17 of the spring ring 15 via three contact surfaces 18, the socket 2 at the annular recess 14. Further contacts the spring ring 15 over its tendons 19 three more contact surfaces 20 on the outer wall 21 of the cylindrical outer conductor contact sleeve 4. Through these contact surfaces 18, 20 may be a very good contact reliability between spring washer 15 and bush 2 or plug head 3 can be ensured.
- the spring ring 15 is in the present embodiment as electrically conductive wire, which is typically spring steel contains, trained.
- the wire diameter d1 of the spring ring 15 is typically oriented at the height h of the annular Recess 14 or advantageously also on the Diameter of the snap groove 6.
- the diameter d2 of the annular recess 14 should at least be minimally smaller than twice the radius r1 of the Spring ring 15, wherein the radius r1 of the spring ring 15 defines is considered the distance of the center of the spring ring 15 to one of its outer corners 17 in the unloaded state of the Spring ring (see dashed contour in Fig. 2).
- the Einrastrille 6 serves for a fixation of the spring ring 15 on the outer wall 21 of the outer conductor contact sleeve 4, whereby the contact surfaces 18 are increased there and gives an improved electrical contact. To the another is to prevent the Einrastrille 6, that the plug head 3 accidentally releases from the socket 2.
- the best Results arise when the spring ring 15 and the Einrastrille 6 have the same diameter d1 and the spring ring 15 the Einrastrille 6 in a maximum of 120 ° contacted.
- cylindrical trained outer conductor contact sleeves 4 at the socket-side outer wall 21 is approximately the same Diameter d3 as the inner walled annular surface 13 of the socket 2 on.
- the spring ring 15 By a movement of the plug head 3 in the insertion direction I. the spring ring 15 is pressed into the annular recess 14.
- the annular recess 14 serves the spring ring as a guide and indicates the direction of movement II of the spring ring 15 before.
- Through the insertion phase 7 on the plug head 3 is ensures that the spring ring 15 is slow and not abrupt is pressed into the annular recess 14. To this Way can be an undesirable jamming of the spring ring 15 avoid.
