Description
The present invention relates to a kind of by claim 1 contactless high frequency connectors as described in the preamble.
Two high-frequency components, for example the high frequency between coaxial cable and amplifier, antenna assembly or other electronic devices connects usually and connects realization by means of coaxial connector.For example the inner and outer conductor of concentric conductor connects by screw thread (cooperation) or Elastic Contact by means of corresponding contact pressure.This interconnection technique may be very expensive in senior plug-in connector.
In addition, recommend a kind of electrical cnnector that is used for being contained on the conductive plate by EP0 391 257 B1.This connector has a nipple that is used for outer conductor.For with vertically be coupled non-contactly with a relative connector at the shell surface of the outer conductor of the metallic plate that radially extends, be provided with non-electric contacts, it is set within the connector outline.Secondly also need the spring card base of a conduction, it is set within the outline for this reason, and the noncontact element keep-ups pressure with the external conductive casing face and contacts.Inner wire is pressed the coaxial cable conduction contact that traditional approach is connected with desire.
By the known a kind of similar known prior art in this respect of US6 414 636 B1.According to this part open source literature, recommend a kind of connector, by its coaxial cable can with electrical equipment, that is housing, be installed in electric device in the housing, cabinet or the like and connect.
Here, connector at one end has a coaxial fitting, and coaxial cable can be connected above it, and is by setting up the conduction contact of internal and external conductor.
In one embodiment, the other end of connector is provided with a relative connector vertically at the connecting plate that radially extends, and it can connect the housing wall mechanical connection that passes a dielectric Connection Element (being made up of the direct current shorting stub) and an electronic equipments that adopts a conduction under the dielectric situation in the centre.Therefore outer conductor non-contactly with the housing coupling of an electronic installation.Directly interior with the being arranged on housing joint conduction of inner wire is connected.
Another embodiment by this part open source literature, in order to set up the noncontact coupling of outer conductor, be provided with two and distribute and have the double-vane edge shape chip component of the side direction dislocation of the layout type that distributes by a kind of U-shaped along the vertical fork-shaped of connector, they connect in the centre under the dielectric situation and are connected with a for example coupling plate high frequency that is electrically connected the purlieu parallel connection ground connection of housing.That is to say and realize the coupling of noncontact outer conductor thus.
Inner wire can conduct electricity connection equally mutually, perhaps also can form by two chip components that distribute that are parallel to each other, one of them is connected with electronic device or control unit, and another chip component is electrically connected with Elecrical connector, wherein two sheet inner wire piece noncontact couplings.
Basically, know a kind of device that has the noncontact coupling by GB 2 187 599 A.Yet it does not involve connector, but involves coaxial switch, and wherein internal and external conductor is fixed, and only switch element can move.By adopting the inner wire bridge plate or can carrying out the power transmission by other moving meters.
In a embodiment, be provided with inner wire bridge plate as switch element by this part open source literature.
The objective of the invention is, provide a kind of through improved high frequency connectors.
According to the present invention, this purpose realizes according to feature given in claim 1 or 3.Favourable structural design provides in the dependent claims.
The invention provides and a kind ofly compared with prior art carried out improved connector aspect two, it brings significant advantage for the extensive application in high frequency technique.
May imagine in principle, not only contactless high frequency connectors will be discussed, and address " condenser type high frequency connectors ".But this notion is not exclusively correct.Only be far smaller than λ/4 o'clock, just have the capacitive couplings of lead at conductor length L.But the present invention adopts big in comparison length.Thus, can rename as the noncontact lead is coupled on the most basic meaning and do electric capacity and inductance leads coupling.Therefore mainly be to say " contactless high frequency connectors " below.
By the scheme imagination of claim 1, contactless high frequency connectors are made coaxial.That is to say preferably have the noncontact coaxial conductive connection that a coaxial connection of noncontact and that is used for inner wire is used for outer conductor by high frequency connectors of the present invention.Therefore the coaxial cable that connects also can rotate with respect to connector, and the conduction switching performance is not had adverse effect.Especially need carry out continuous 360 ° when rotatablely moving at for example member, for example because this is one the 360 ° antenna assemblies of rotation continuously, its stube cable is connected with half of high frequency connectors, and it is favourable so.
Propose a kind of contactless high frequency connectors according to the present invention by the scheme of claim 2, its high-frequency component can be than much simple and economical as to interconnect by prior art.Connect with noncontact and can get rid of with classical connections (method) problem that situation occurred of end face and Elastic Contact for example.Especially poor electrically contacting causes the intermodulation problem, and it particularly may cause the interruption of receive path when the mobile radio communication.Connect separating of realization machinery and electric work energy by noncontact.Therefore be threaded or lock and to satisfy the electric work energy.Contactless connector can also mate with existing AN connector (for example 7-16 connector) in addition.Contactless connector also has very big advantage in high frequency measurement and inspection technology, because it can for example be used as the quick connector of no IMA (intermodulation).
Make like this by the scheme by claim 1 and 2 of the present invention, make no matter be inner wire or preferably all noncontact couplings of outer conductor.If but otherwise particular application for example inner wire classically preferably by means of Elastic Contact and for example only outer conductor be coupled non-contactly or, may be very favourable.Also avoided dual cooperation in this case, because the noncontact coupling unit is insensitive for error.
In a kind of particularly preferred form of implementation, contactless high frequency connectors are made non-contacting on the one hand, make on the other hand coaxial, thereby occur cumulatively and give above-mentioned advantage.
In a kind of particularly preferred form of implementation of the present invention, it is long that the same shaft length of noncontact inner wire and/or outer conductor coupling has λ/4, and be with respect to frequency to be transmitted, the average frequency of frequency range especially to be transmitted.In other words the coupling of inner wire and/or outer conductor is made by the mode of line transformer.Different therewith, in the improvement structure of the same imagination of the present invention, matching structure also can be realized under the situation of λ/4 axial arrangement length of avoiding the coupling of inner wire and/or outer conductor, if that is to say corresponding matching structure is set complementally particularly.Particularly this measure of situation for little coupling surface and/or short coupling length may be favourable.
Can make like this by connector of the present invention, that is, it is fixedlyed connected with affiliated high-frequency component respectively, and these elements can directly connect by connector.That is the element of connector itself is not that concentric conductor by flexibility is connected with the high-frequency component that is connected back or front, but directly is connected with them, obtains compact firm topology layout thus.
At last, a plurality of contactless connectors can also be merged into a noncontact manifold connector within the scope of the invention.Here be connected the assembling aspect by noncontact and obtain very big advantage.In traditional electrically contacting in the technology, contact when being coupled, being avoided of being occurred with end face by noncontact of the present invention with the problem that may occur for Elastic Contact.Therefore can realize the connection of a manifold connector connector conduction with an assembly unit.Will not peg graft seriatim by all connectors.
Mention above, within the scope of the present invention for AN connector for example 7-16 or N-cover (N-Buchsen) noncontact in other words that also can realize being coupled connect.Here the present invention also is particularly suitable for the transmission of HF link, wherein also can realize depending on the desirable direct-current coupling of noncontact coupling, and particularly realization is connected with the conduction of amplifier, measuring instrument or the like if desired, and this is advantageous.
At last, can also realize big frequency bandwidth within the scope of the present invention.
Described high frequency connectors of the present invention also can be used for the shell structure of noncontact, potential-free, for example are used for the measuring chamber of radioshielding.At last, described connector also can be by simple O shape circle (for example being made up of silicone) in its outer conductor coupling part (for example in cup-shaped position) axial seal.Thereby the connector connection also can be used in the perimeter.
By means of accompanying drawing the present invention is done more detailed explanation below.Wherein specifically expression:
Fig. 1 is at the axial cutaway view of signal of next noncontact coaxial connector of situation of realizing coupling of noncontact inner wire and the coupling of noncontact outer conductor;
Fig. 2 is used for illustrating the embodiment slightly different with Fig. 1 that is coupled with the noncontact of standard cover;
Fig. 3 by Fig. 1 not with the schematic diagram of the embodiment of mechanical fixation;
The embodiment of Fig. 4 one modification is wherein by adopting non-conducting material (dielectric) to realize the localized immobilization of two elements of connector;
A kind of modification of Fig. 5 Fig. 4 wherein makes two element mechanical fixation of connector by the method for filling up the cavity between the connecting element with insulating material (dielectric) fully;
Another embodiment of Fig. 6, wherein two of connector elements are by being preferably disposed on the relative position that outside independent mechanical fastening system maintenance interfixes; With
Fig. 7 to 9 has other embodiments slightly different with the foregoing description of the noncontact coaxial connector of different-diameter.
Schematically illustrate among Fig. 1 two high-frequency components 1 and 1 ', they should pass through together spindle guide line 3,3 ' connection respectively.Be this two concentric conductors 3,3 ' interconnect by means of the coaxial high frequency connectors 5 of a noncontact.
Here connector 5 has two coupling parts 7 and 9.
The coupling part 7 that wherein is positioned at Fig. 1 left side is connected with high-frequency component 1 conduction with concentric conductor 3 and by it, and inner wire 7 ' a (it comprises affiliated inner wire section 7a) is connected with the outer conductor 3b conduction of concentric conductor 3 with inner wire 3a, the outer conductor 7 ' b (it comprises affiliated outer conductor section 7b) of concentric conductor 3 in addition.
Correspondingly in the coupling part 9 on Fig. 2 right side with affiliated concentric conductor 3 ' with high-frequency component 1 ' be connected in this wise, make inner wire 9 ' a (it comprise under inner wire section 9a) and concentric conductor 3 ' inner wire 3 ' a, outer conductor 9 ' b (the outer conductor section 9b of its coupling part 9 under comprising) and concentric conductor 3 ' outer conductor 3 ' b conduct electricity and be connected.
Can see that in the embodiment shown inner wire section 7a is designed to sleeve shaped, have an axial inner wire hole 17 for this reason, it makes the form of the blind hole of the axial distribution of end face under the inner wire section 7a.
Correspondingly second coupling part 9 be designed to the form of an inner wire pin 19 with its coefficient inner wire section 9a, it inserts inner wire hole 17 non-contactly when the service position.
It can also be seen that by the embodiment that schematically illustrates axially adjacent with inner wire hole 17 or inner wire pin 19 inner wire section 7a and 9a design to such an extent that have identical diameter or a roughly the same at least diameter by Fig. 1.
Can see that by schematic diagram outer conductor section 7b is designed to sleeve shaped, and have a diameter that is equivalent to the outer conductor section 9 ' b of second coupling part 9 by Fig. 1.But the second outer conductor section 9b is provided with one cup-shaped 109 in the coupled section zone, make outer conductor section 9b by this cup-shaped 109 sleeve shaped ending, wherein cup-shaped 109 internal diameter is slightly larger than the external diameter of the outer conductor section 7b of the first pontes 7 in the service position ends at cup-shaped head at least.
Because no matter be inner wire section or outer conductor section neither within it the surface go up or on its outer surface, also on the end of its end face side, do not contact, therefore do not realize non-contacting internal and external conductor coupling.
By inner wire coupling surface 107a and 109a and the outer conductor coupling surface 107b and the 109b realization noncontact coupling of making the concentric locking collar cartridge form respectively.The size of internal and external conductor coupling surface, that is the length of internal and external conductor coupling surface, can be according to mechanical dimension determine to select different mechanical length. Inner wire section 7a and 9a and outer conductor section 7b and 9b, that is particularly outside in cup-shaped 109 zone on the conductor segment 9b, the best electrical length of noncontact coupling by means of a λ with respect to frequency to be passed or frequency band to be passed/4 carry out.The size of λ preferably roughly is equivalent to the wavelength X of the average frequency of frequency range to be passed.
The length that is to say cup-shaped coupled structure can be adjusted in this wise, makes the open end of lead play the idle stroke effect respectively, and the short circuit effect is played in inside.Coupling part is worked as direct connection in high frequency region thus, thereby realizes the stepless transition of internal and external conductor.Therefore do not need matching structure for impedance matching.Yet the coupling of cup-shaped head also can be carried out with different axial lengths.Particularly may also need in connector, establish an additional matching structure under the situation of short axial coupling length in other words thus at the coupling surface that reduces.
Non-conductive mechanical locking device 51 also can be connected or acting in conjunction with 9 with two coupling parts 7 with 55, and non-conductive mechanical locking device for example contacts interfix (more clearly realizing among this Fig. 6 that also will illustrate in the back) by screw thread.Therefore first and second mechanical connecting part 51 and 53 mechanical connection mutually is so that interfix on the non-contacting position of stipulating the electricity piece of coupling part 7 and 9 by them.
As mentioned above, by adopting nonconducting mechanical acting in conjunction locking device 51 can keep not contacting mutually with 9 with 55 two coaxial coupling parts 7.Therefore adopt air usually as the dielectric between two coupling parts 7 and 9.Can relatively rotate mutually by two coupling parts 7 of coaxial configuration and 9, and not make coupling variation or undermined thus.Even adverse effect when 9 are not inserted into identical insertion depth, is also got rid of to a great extent in two coupling parts 7.
As can be seen, different with illustrated embodiment, two high- frequency components 1 and 1 that connect by connector 5 ' can be respectively and affiliated coupling part 7 with 9 firmly and directly be connected, make high-frequency component 1 and coupling part 7 and high-frequency component 1 ' with the firm construction unit of coupling part 9 formations one.In other words need be not coaxial in the employing shown in Fig. 1 (normally flexible) lead 3 and 3 '.
With the noncontact coupling of schematic view illustrating and standard cover 31, the standard cover has an inner wire section 9a who schematically illustrates and outer conductor section 9b in the embodiment shown among Fig. 2.Wherein inner wire section 9a can be designed to socket and sleeve shaped in principle, and a coaxial plug that has corresponding plug-shaped inner wire can be inserted in its () the inside, connects to set up conduction.
Can under situation about adopting, realize the connection of noncontact connector by means of common standard cover 31 corresponding to the coupling part 7 of the embodiment that press Fig. 2.Now this coupling part 7 has a corresponding inner wire section that has a cup-shaped inner wire hole 17.Inner wire hole 17 has bigger radial dimension, and it is selected like this, makes inner wire section 9a to insert non-contactly in this hole.
Because in this case must be from this point, promptly, the noncontact coupling surface of internal and external conductor is not equal to the conductive lengths of λ/4 (wherein λ is equivalent to wavelength) in frequency band to be transmitted or frequency to be transmitted district, the conductive lengths that particularly is not equal to λ/4 for the treatment of defeated frequency band average frequency, but coupling surface is provided with impedance-matching device 41,43 in addition in this embodiment because reasons in structure is compared with embodiment by Fig. 1 does lessly.This impedance-matching device can be made on the corresponding inner wire section 7a and/or affiliated outer conductor section 7b of coupling part 7.Inner wire 7 ' a has on certain axial length and the different diameter of inner wire section 7a that axially is connected its front or back in the embodiment shown for this reason.Realize for impedance matching by means of desirable impedance conversion thus when time-frequency band.
Secondly can see with reference to Fig. 2, no matter be that outer conductor 7b or inner wire 7a can have less radial dimension.That is to say that the outside dimension of inner wire section 7a can be selected smallerly so, makes this inner wire section 7a can insert in the hollow inner wire section 7a of second coupling part 9 if the inner wire section 9a of standard cover 31 makes hollowly.Also have conversely possibility for outer conductor, the external dimensions of the outer conductor 7b of coupling part 7 or diameter are selected less than coupling part 9 or are overlapped the nominal internal diameter of 31 outer conductor 9b in this structure.
Coupling part 7 and 9 or coupling part 7 and standard overlap the whole structure that can insert mutually of another coupling part of 31 forms can be by means of nonconducting fixing or locking device 51,53 carry out in this wise, that is, make the noncontact coupling of internal and external conductor can not adopt the non-conductive insulating material between them to realize.In other words, that is to say and between coupling surface, only adopt air.But irrespectively also can adopt other common insulating material, particularly dielectric in this zone between coupling surface therewith.
Fig. 1 and 2 represents such embodiment, and wherein the noncontact coupling of internal and external conductor is definitely contactlessly carried out in two coupling parts, that is to say not by adopting insulator or the dielectric method that fixedly is bumped into.In Fig. 1 and 2, dielectric only is made up of air under the situation that adopts corresponding connector in atmosphere.
Here, obtain a kind of flexible program by Fig. 3, two high-frequency components 1 and 1 ' directly fixedly connected with 9 wherein with coupling part 7, make no longer need conducting line segment 3 and 3 '.
Embodiment by Fig. 4 represents a kind of flexible program,, for the relative fixed of two coupling parts 7 and 9, uses the local fixing that has non-conducting material 51,53 here.These non-conducting materials 51 are used on the different positions with different moulding with 53.These non-conducting materials for example are used for making inner wire 9a to fix with respect to inner wire 7a with the form of isolating frame or spacer ring in by the embodiment of Fig. 4, and are here in the free end zone of inner wire 9a.Second kind of insulating material is mainly as isolating frame, insertion depth with restriction coupling part 7 and 9, and in by embodiment shown in Figure 4, be arranged in such zone for this reason, in this zone, the end of coupling part 7a end face one side and the step 209a adjacency on the inner wire 9a, original inner wire section 9a is transformed into the inner wire conducting line segment 9 ' a that has big material cross-section in this end.
Correspondingly, the isolating frame 53a and the 53b of non-conductive medium 53 forms is set, connects to avoid the conduction between outer conductor section 7b and the 9b.Here a section 53a who has insulating material 53 is arranged on the end face side free end of outer conductor section 9b equally, and another insulating material 53 is arranged on the end of end face side of another outer conductor section 7b of insertion.This material 53b also makes like this, makes to limit two insertion depths that coupling part 7 is relative with 9 thus mutually.
Different therewith, Fig. 5 then points out, the coherent material 51 that the isolated component 51a of the positioned opposite that is used for two inner wires of correspondingly separating in Fig. 4 and 51b also can be made of one.For the isolating frame 53 of two outer conductor sections too.Here also only use a unique isolating frame material, isolated component 53a that it will single application in Fig. 3 and the part that 53b links into an integrated entity.
In pressing the embodiment of Fig. 6, as adding of Fig. 1, to represent clearlyer, what be positioned at the outside is that non-conductive mechanical locking device 51 is fixedlyed connected with the outer conductor of coupling part 9 with the outer conductor of coupling part 7 on the one hand with 53 equally, and they can for example interfix on corresponding flange by screw 61 then.Determine axially and the radially relative position of two Connection Elements 7 and 9 thus definitely.
More be briefly described below by the embodiment in Fig. 7,8 and 9 the axial cutaway view of signal, point out different with the foregoing description.
Be with the main distinction by the embodiment of Fig. 7 to 9, in the coaxial connection of noncontact, adopt conducting line segment with different-diameter by the embodiment of Fig. 1 to 6.If but two connectors have or have substantially identical characteristic impedance Z
1=Z
2, that is to say that characteristic impedance differs to be no more than 20% that preferably be no more than 10% or 5%, corresponding inner wire section and/or outer conductor section 7a, 9a, 7b, 9b also can be coupled when different-diameter so.Wherein, in by the embodiment of Fig. 7, adopt air (perhaps other gaseous dielectric mediums) as previously mentioned, wherein have only air just to be worthy of consideration being used for atmospheric conditions following times usually as dielectric.
In the embodiment that presses Fig. 8 and 9, for example illustrate for the first pontes 7: it has a cable jacket 71 from outside to inside, and it for example is made up of suitable plastic such as PVC, FEP or the like.Below the cable jacket 71 of insulation, be the outer conductor 7 ' b that has corresponding outer conductor section 7b then.Sell shape inner wire 7 ' a in the embodiment shown and affiliated inner wire section 7a is arranged on the center coaxially, this inner wire section separates with outer conductor or outer conductor section 7 ' b, 7b by dielectric 75, dielectric can for example be that plastics or the like are formed by corresponding suitable insulation material equally, but equally also can be made of air.
In all Fig. 7 to 9, can see, no matter be the diameter of two outer conductors or two coupling parts 7 with 9 inner wire is different, wherein the diameter of two leads is than being identical, that is it is identical separately or roughly the same at least for the ratio of two coupling parts 7 and 9 inner wires and outer conductor, make with its deviation less than 20%, especially less than 10%.Can guarantee that thus two coupling parts 7 of connector have identical characteristic impedance with 9, that is to say Z
1=Z
2So for example coaxial cable also can directly insert in the connector, that is coaxial cable constitutes the coupling part 7 be positioned at the Fig. 8 or 9 left sides, and it can only insert in another coupling part 9.Inner wire stretches out with effective conductive lengths L=λ/4 in this case, that is axially stretches out outside the affiliated outer conductor section with corresponding length.Deviation should be less than 20%, preferably less than 10%.If λ is equivalent to the mean wavelength in frequency to be transmitted district, just reach best numerical value so.Like this outer conductor coupling just can with or carry out without the diameter step, just as exemplary expression in each accompanying drawing.
Should illustrate that in addition expression belongs to coupling part 7 and is drawn in the left side in Fig. 1 to 6 inner wire 7 ' a or inner wire section 7a are sleeve shaped, the inner wire section 9a that belongs to coupling part 9 on figure the right is a pin shape.This also can make opposite, and for example can be such according to what Fig. 7 to 9 saw, and inner wire 7a is designed to pin shape now in these several figure, and inner wire 9a is designed to sleeve shaped.For outer conductor 7b and 9b basically too, they its geometrical aspects can design and opposite by the embodiment of Fig. 1 to 6, that is be different from drawn view, outer conductor section 7b and 9b are designed to the situation of similar miss change.
