High precision of the connection, and at the same time a reduced insertion force, are achieved in such a multiple coaxial cable plug connection in that the first coaxial contact arrangements (26) are floatingly supported in a first housing (11), while the second coaxial contact arrangements (27) are permanently installed in a second housing (21).

Description

In the past, various proposals have been made, which have referred to multiple connectors, in which several coaxial cables are connected in a mating operation at the same time with a circuit board high frequency. In such multiple coaxial cable connectors not only the contact arrangements of the individual connection points must be aligned with each other, but it must also be ensured that the RF connection is up to the highest frequencies with the lowest possible attenuation, In addition, care must be taken to ensure that a multiplicity of connection points or coaxial cables to be connected, the plug-in forces to be expended during plug-in operation remain manageable.

From the publication WOA1-92 / 22943 For example, a coaxial connector system of high density for use in printed circuits is known in which on the cable side provided with a coaxial contact arrangement cables are inserted into holes of a grouping plate and locked there. A plurality of array plates are held in parallel in a housing with the coaxial contact assemblies protruding forwardly out of the housing and inserted into corresponding bores in a counterpart located on the circuit board. The electrical contact is made for the inner conductor via a central pin and for the outer conductor via a laterally arranged in the bore contact tongue in the counterpart. In this solution, the structure is very simple and the insertion force comparatively low. On the other hand, this solution is unsuitable for higher and highest frequencies in the GHz range because of the unfavorable contact geometry and lack of precision.

From the publication EP-A1-0 582 960 an RF coaxial connector is known in which the coaxial mating connector for the coaxial connector are integrated in a metal monoblock, which is the common outer conductor for all mating connectors forms. The coaxial connector itself are combined by means of a common mounting plate to form a unit arranged on a plate and fastened by means of press-in contacts in a certain pitch. A flexible alignment of the individual connectors to each other is not possible here.

The publication WO-A2-98 / 33243 shows a comparable RF coaxial connector, in which instead of the metal block in the mating connector, a plastic housing with metallized inner wall is used as an outer conductor. Again, a flexible alignment with the individual connectors is not possible.

In the publication US 6,409,550 will (especially in the Fig. 7 ) discloses a connector module in which a plurality of individual connectors are arranged on an insulating slider, which slider is mounted transversely displaceable in the module. The slider is mounted in a track groove and carries adjusting pins. When the modules are mated, the alignment pins dip into corresponding alignment holes in the opposite module and slide the slider accordingly to ensure the desired alignment of the connectors. This type of alignment is thus limited to the slider as a whole, so that alignment of the individual fasteners is not possible on their counterparts.

It is therefore an object of the invention to provide a suitable in particular for use in circuit boards multi-coaxial cable connector in which due to the flexible alignment of the individual connectors each other a very high precision in the mated connections and thus an achievable operating frequency in the two-digit GHz Range, in particular up to 40 GHz, at the same time well manageable insertion forces and sufficient mating cycles is achieved, and specify a method for their installation.

The object is solved by the entirety of the features of claims 1 and 10. Essential to the invention are two connectors, wherein the first connector has a plurality of transverse to the connector axis juxtaposed first coaxial contact assemblies and the second connector is fitted with matching to the first coaxial contact arrangements second coaxial contact assemblies, and wherein the first coaxial contact assemblies each at the end an associated coaxial cable is attached. The advantageous properties of the connector according to the invention are achieved in that the first coaxial contact arrangements are floatingly mounted in a first housing, while the second coaxial contact arrangements are fixedly mounted in a second housing, that the first coaxial contact arrangements for floating mounting in the first connector transverse to the plug axis latching into a bearing plate are inserted, that the bearing plate is formed as a comb with outwardly projecting teeth, between which receiving spaces for receiving the inserted first coaxial contact arrangements are arranged, that the bearing plate is held in the first housing with radial play, and that the bearing plate or The comb is made of a plastic.

In this way, when inserting the connector, the (high-precision) first and second contact arrangements can align in pairs, so that at the same time a HF-moderately optimal plug contact and a low insertion force can be achieved.

As a result, the assembly of the connector is greatly facilitated.

The positioning of the first coaxial contact arrangement can thereby be facilitated by the fact that the first coaxial contact arrangement has a circumferential latching groove whose outer diameter is adapted to the diameter of the receiving section.

Preferably, the first housing has a continuous in the direction of the plug axis, open at the ends of the interior space, wherein the bearing plate or the comb is held in recesses provided for this purpose on the first housing.

According to another embodiment of the invention, the first contact arrangements with the associated coaxial cable are firmly connected, in particular soldered.

Furthermore, it is advantageous if the second housing consists of a metal or a metallized plastic and has a number of second coaxial contact arrangements corresponding number of graduated in diameter holes, and if the second coaxial contact assemblies with its base firmly seated pressed into the holes are.

In order to support the alignment of the first contact arrangements on the second contact arrangements, in particular in the case of rigid coaxial cables, a cable guide can be provided according to another embodiment of the invention for guiding the coaxial cables emerging from the first contact arrangements.

In the Fig. 1 and 2 are the basic elements of a multiple coaxial cable connector 50 according to an embodiment of the invention for the connection of multiple coaxial cable with a (not shown) circuit board 52 (PCB, multilayer board, etc.) reproduced. The multi-coaxial cable connector 50 comprises a multiple connector strip 20 which is attached and connected to the circuit board 52 by means of SMD mounting technology, and a multiple connector strip 10 which is inserted into the multiple connector strip 20 along a connector axis 51 (arrows in FIG Fig. 1 ) is inserted.

The multiple connector strip 20, the design and internal structure in the Fig. 12 to 16 are shown, consists of a housing 21 which is formed as a metal block, and in the present embodiment 2 parallel rows of 8 each graduated in diameter axial bores 22 are introduced. The holes 22 of the two rows have a standard distance (4mm in the present example), which corresponds to the distance of the corresponding plug inserts (26) in the multiple connector strip 10. With each of the 16 holes 22, a coaxial cable connection can be realized, so that the multiple coaxial cable connector 50 of the embodiment allows the simultaneous pluggable connection of a total of 16 coaxial cables.

Like from the Fig. 2 . 12 and 14 it can be seen, in the holes 2 each have a contact assembly 27 is inserted (pressed), the in Fig. 16 individually shown and their structure Fig. 14 is apparent. The contact assembly 27 has an annular base 37 with a Stop 38. It is pressed with the base 37 to form an annular gap 45 in the bore 22.

In an axial bore of the base, an inner conductor 42 is concentrically arranged, which is centered and held by means of an insulating piece 41 in the base 37. The inner conductor 42 terminates flush with the circuit board 52 with the mounting surface 23 of the housing 21 ( Fig. 2 . 14 ) and is from below through the opening 46 ( Fig. 15 ) accessible while the insulating piece 41 is set back. On the insertion side, the inner conductor 42 has an enlarged diameter centerpiece 43 for impedance matching and then merges into a tapered contact pin 44. Center piece 43 and contact pin 44 are concentrically surrounded by a ring of axially oriented, separated by slots 49 contact arms 39, which emanate from the base 38 and can deflect radially with their free ends. At the free ends of the contact arms 39 are outside Kontaktwülste 40 are arranged, with which the contact arms 39 when inserting an electrical contact with the inner wall of the contact sleeve 29 (FIGS. Fig. 5 ) of the associated contact assembly 26 in the counterpart (multiple connector strip 10) produce.

The metallic housing 21 of the multiple connector strip 20 forms a common outer conductor for all individual connectors. It also has an asymmetrical cross-sectional contour with a coding 17 'in the form of an obliquely protruding corner, which with a coding 17 on the housing 11 (FIG. Fig. 7 ) of the multiple connector strip 10 corresponds and ensures that the two connectors can be mated only in a predetermined manner. In the mounting surface 23 of the housing 21 of the holes 22 to the outside leading recesses 24 are provided ( Fig. 15 ), which make it possible to lead the inner conductor 42 on the upper side of the circuit board 52 isolated from the housing 21 to the outside. For positioning the housing 21 on the circuit board 52 are arranged in the housing 21 asymmetrically arranged guide holes 47 and 48 between the two rows of holes 22 ( Fig. 15 ).

As already mentioned, each contact arrangement 27 in the multiple connector strip 20 is assigned a corresponding contact arrangement 26 in the multiple connector strip 10. The contact assembly 26, whose construction Fig. 5 can be seen, consists of acting as an outer conductor contact sleeve 29 in which concentric an inner conductor 31 is centered and held by means of an insulating piece 33. The inner conductor 31 goes to the mating side in a female contact 32, which receives the contact pin 44 of the contact assembly 27 during insertion. At the other end of the inner conductor 31 receives the inner conductor of a coaxial cable 28, at the end of the contact assembly 26 is soldered. The outer conductor of the coaxial cable 28 is connected to the rear end of the contact sleeve 29. To the mating side, the contact sleeve 29 is flared on the inside to facilitate the inlet of the contact arms 39 of the contact assembly 27. The electrically conductive contact parts of both contact arrangements 26, 27 are preferably made of CuBe and are surface-treated, in particular gold-plated.

To facilitate the insertion of the multiple connector strip 10 in the multiple connector strip 20 a pairwise alignment of the contact assemblies 26, 27 each other and thus at the same time reduced insertion force to achieve high precision in the mated connection, the operating frequencies allows up to 40 GHz, the coaxial cable 28 with the soldered at the ends of contact assemblies 26 in the housing 11 of the multiple connector strip 10 floating. For this purpose, a designed as a comb 18 bearing plate is used, which in Fig. 8-10 is shown separately. The comb 18, which preferably consists of a suitable plastic, is adapted in its outer shape to the cross-sectional contour of the housing 11. It has on the outer circumference a plurality of outwardly projecting teeth 19, 19 a, b, between which receiving spaces 25 are left free for the contact assemblies 26. Each of the receiving spaces 25 each comprises a circular receiving portion 25a adapted in diameter to the first coaxial contact arrangement 26 and a straight insertion portion 25b which connects the receiving portion 25a to the outer space. The circular receiving portions 25a correspond to their lateral arrangement, the holes 22 in the housing 21 of the other multiple connector strip 20. The insertion section 25b has a width b ( Fig. 8 ), which is slightly smaller than the diameter D of the receiving portion 25 a, in such a way that the first coaxial contact assembly 26 is laterally inserted through the insertion portion 25 b in the receiving portion 25 a inserted. In the axial direction held in the comb 18 contact assembly 26 is fixed by the fact that on the contact sleeve 29, a circumferential locking groove 30 is formed ( Fig. 11 ) whose width corresponds to the thickness of the comb 18.

If all 16 coaxial cables 28 with their soldered contact arrangements 26 are snapped into the respective receiving sections 25a in the comb 18, the comb 18 fitted in this way is pushed from behind into the interior 12 of the housing 10 and kept floating there. This process is different, depending on whether the housing 11 is made of metal or of a yielding plastic. In the illustrated embodiment, it is assumed that a housing 11 made of metal. In the wall of the housing 11, two parallel slots 13, 13 'and 14, 14' and 15, 15 'are provided on all four sides. The lower, wider slots 13, 14 and 15 (slot width = comb thickness) receive the comb 18 and hold in with radial play. The upper, narrower slots 13 ', 14, and 15' each define a web lying between the pairs of slots, which can be used for caulking the comb 18 in the housing 11: The middle teeth 19 a of the comb 18 are made longer than the other teeth 19 b , Corresponding to the longer teeth 19a, a recess 16 which is adapted to the longer teeth 19a and which extends from the back to the front and ends in the region of the slots 13 is mounted in the housing 11 on opposite walls. When inserting the comb 18 into the housing 11, the longer teeth 19 a in the recesses 16 can be moved freely forward ( Fig. 4 ) until they abut at the level of the slots 13 at the end of the recess 16. The webs between the slots 13, 13 'or 14, 14' and 15, 15 'can then be caulked inwardly to hold the comb in this position.

If the housing 11 is made of a plastic, the webs can be used as a locking means, the elastically escape when inserting the Kamms18 outwardly and snapping back behind the comb 18 latching. Other locks are also conceivable.

If, during insertion, the housing 11 of the first multiple connector strip 10 is pushed over the housing 21 of the second multiple connector strip 20, the contact arrangements 26 held in the comb 18 with the coaxial cables 28 connected can adjust to the opposite contact arrangements 27 due to the play, so that very precise coaxial connections can be achieved result.

With comparatively rigid coaxial cables 28, considerable side-acting forces can act on the first contact arrangements 26 attached to the ends and snapped into the comb 18, which effects a tilting of the first contact arrangements and complicate the plug-in procedure. To avoid such difficulties safely, according to Fig. 17 to 20 a cable guide 53 are used, which aligns the coming out of the first housing 11 coaxial cable 28 parallel and simultaneously acts as a kink protection.

The cable guide 53 is designed as a one-piece body made of plastic ( Fig. 18 ) and has a number of parallel through-holes 54 for the passage of the coaxial cable 28, which correspond in number and arrangement to the holes 22 in the multiple connector strip 20. The diameter of the through-holes 54 may be selected so that the ready-made coaxial cable 28 can be pushed with the first contact assemblies 26 before they are then snapped into the comb 18.

The edge contour of the cable guide 53 corresponds to the edge contour of the inner space 12 of the first housing 11. In particular, a thickening 55 is provided on the long sides of the cable guide 53, which is adjacent to the recess 19 on the inner wall of the first housing 11 is adapted and serves to guide the cable guide 53 in the housing 11. At the bottom of the cable guide 53 laterally protruding locking lugs 56, 57 are arranged on each of the four sides, which engage in the insertion of the cable guide 53 in the first housing 11 in the upper slots 13 ', 14', 15 '. In the illustrated embodiment, the inserted cable guide 53 closes almost flush with the upper edge of the first housing. However, it is also conceivable that the cable guide protrudes from the housing 11 to the rear more or less strong to further strengthen the support and orientation of the coaxial cable. Furthermore, it is conceivable that the cable guide is executed by encapsulation with a plastic compound and / or is firmly bonded to the first housing.
