Comply with conductor:

In various embodiments, this equipment is to comprise that the distortion with one or more deformable component and/or deflection member complies with the contactor of conductor.These parts begin to extend from the conductor of this contactor, so that they can contact the electric contact of the structure of holding this contactor.By deforming and/or deflection when contacting with the reception structure, these parts guarantee that this conductor has the ability of complying with.If these parts conduct electricity, then in when contact, this conductor can receive structure with this, and to carry out the Electricity Federation logical.Can change the specific arrangements or the configuration of this deformable component or each deformable component according to the embodiment of the invention.

Figure 1A to C illustrates at least one embodiment.As shown in the figure, contactor 100 comprises center conductor or inner conductor or first conductor 110, spacer 120 and external conductor or second conductor 130.With coaxial manner and/or concentric manner centre of location conductor 110, spacer 120 and external conductor 130.As shown in the figure, contactor 100 is positioned at and receives above the structure 150, and this reception structure 150 comprises base or substrate 152 and position contact or pad 154 thereon.Arrange pad 154, so that can receive this contactor 100.Contact 154 comprises: center bonding pads or signal pad 156 are used for receiving center conductor 110; And external pads or ground pad 158, be used for when this contactor 100 these structures 150 of contact, receiving external conductor 130.

This contactor 100 can append to and be positioned at (not shown) on the cable that receives structure 150 relative ends.The cable of being installed can be a coaxial cable, and this cable can be self-regulating, so that this cable can move with the displacement of contactor 100.

According to this embodiment, in certain embodiments, center conductor 110 can be center pin, signal conductor or signal pipe line etc.Center conductor 110 can be used to carry the signal in the contactor 100.Center conductor 110 comprises end 112, and shown in Figure 1B, center conductor 110 has outside diameter d 1.Center conductor 110 can be the cavity twisted wire of solid (not shown), also can be other configurations.In addition, center conductor 110 can be fix, indeformable or indeformable at least basically.Owing to be indeformable, perhaps be indeformable at least basically, so center conductor 110 provides the contactor 100 of specific definite electrical length.The contactor 100 that should determine length is irrelevant with any compliance, distortion and/or the deflection of external conductor 130, will be described further at this.Like this, the variation of the compliance of external conductor 130 does not influence the electrical length of contactor 100.

Center conductor 110 can be comprise such as copper, gold, stainless steel, beryllium-bronze, such as in the multiple material of the electric conducting material of the gilding of gold-plated stainless steel or gold-plated beryllium-bronze etc. arbitrarily.

In certain embodiments, can form center conductor 112,, thereby help to electrically contact so that by 112 having profiled tip in the end.This profiled tip can comprise crown tip, rough surface etc.

Different with center conductor 110, in certain embodiments, spacer 120 can be an insulator, and it can be non-conductor, semiconductor or ESD material.Make that like this spacer 120 prevents between center conductor 110 and external conductor 130 electrical short to take place, perhaps short circuit.Spacer 120 can be used as dielectric.Spacer 120 can also utilize physical method centre of location conductor 110 and external conductor 130, and makes them remain on its relevant position.Spacer 120 can comprise end 122, and this end 122 can be positioned at along all places of the length of contactor 100 arbitrarily.In an illustrated embodiment, end 122, location is so that the end 132 of center conductor end 112 and external conductor 130 extends through end 122 to outside.

Spacer 120 can also be used to control the impedance of this signal.That is, the size and/or the material that change spacer 120 can influence along the impedance of contactor 100 length, will be described further at this.

Spacer 120 can be any one material that comprises in the various materials of pottery, plastics, rubber or other media etc.In certain embodiments, even spacer 120 is air, gas vacuum.Some typical medias comprise and are positioned at Wilmington, the commercially available teflon of the Dupont of Delaware, be positioned at the commercially available foam teflon of the W.L.Gore of Elkton Maryland or inflate teflon, be positioned at Detroit, Polyetherimide (ULTEM) that the GE Plastics of Michigan is commercially available or the like.Spacer 120 can have the DIELECTRIC CONSTANT that can change according to employed material and embodiments of the invention _r

External conductor 130 can be screen, shielded conductor, ground wire, loop etc.That is, according to this embodiment, external conductor 130 can conduct electricity, and as ground wire, screen, loop and/or signal circuit.External conductor 130 can be used to prevent or limit from the amount of signal transmission of contactor 100 or leak amount of crosstalk, RF leakage, EMI and/or the electrical noise of quantity, contactor 100 and other neighbouring devices.External conductor 130 can also be used as benchmark or current circuit path.Shown in Figure 1B, external conductor 130 has inside diameter D 1.

External conductor 130 be comprise such as copper, gold, stainless steel, beryllium-bronze, such as in the multiple material of the electric conducting material of the gilding of gold-plated stainless steel or gold-plated beryllium-bronze etc. arbitrarily.

As mentioned above, in certain embodiments, to controlling, and make it constant relatively, to avoid taking place impedance discontinuity along the impedance of contactor 100.By reducing or eliminate reflection in the contactor, minimize or eliminate impedance discontinuity and can realize the performance improved.Usually, utilize equation E1, can determine this impedance:

z ₀＝√L/C (E1)

Wherein L is an inductance, and C is an electric capacity.Like this, impedance usually and electric capacity be inversely proportional to.For the contactor of coaxial arrangement, in other factors, the dielectric constant of the external diameter of electric capacity and center conductor, the internal diameter of external conductor and the spacer between inner conductor and external conductor is relevant.

Under some particular case, can utilize equation E2 to determine this impedance.These situations are confined to be included in the situation that high frequency has the concentric co-axial conductor of uniform dielectric:

z＝60/√ε _rln(D/d) (E2)

Wherein z is impedance, ε _rBe the dielectric constant of spacer or insulator, d is the external diameter of center conductor, and D is the internal diameter of external conductor.

More generally, for all frequencies, utilize equation E3 to determine this impedance:

Z_{0} = \frac{R^{'} + j 2 πf L^{'}}{\sqrt G^{'} + j 2 π {fC}^{'}} - - - (E 3)

From these equatioies as can be seen, this impedance may be depended on the diameter d 1 of center conductor 110, the diameter D1 of external conductor 130 and the DIELECTRIC CONSTANT 1 of spacer 120.Usually, along with the gap between D and the d increases, this electric capacity reduces, and this inductance raises.Therefore, this impedance reduces along with the reducing of distance between center pin and the ground wire, and at this when increasing, this impedance raises.Certainly, the influence of this impedance is also depended at this there are not specifically described many other factors.

To center conductor 110 and external conductor 130 carry out some change not can appreciable impact contactor 100 impedance.For example, usually, if along contactor 100 external diameter of external conductor 130 is amplified to certain point, and inside diameter D 1 keeps identical, and then this impedance Z nature keeps identical value according to other various factorss that influence impedance.Should note, this impedance is to the variation sensitivity of the limited variation comparison external conductor of center conductor, because because the external diameter of this center conductor is all the time less than the internal diameter of this external conductor, so the influence that the ratio of the external diameter of this inner conductor and the internal diameter of this external conductor is subjected to is bigger.

Different with other equipment, make diameter d and D and relative dielectric constant ε by length along this contactor _rKeep constant, some embodiments of the present invention keep more constant impedance.In addition, in certain embodiments, comply with part around the rotation of this contactor, and therefore change one of diameter d 1 and D1 or the size of the two, control group according to the setting of deformable component (quantity, size etc.) by restriction.

Some embodiments of the present invention also seek along the length of this contactor dielectric constant to be remained unchanged, to prevent impedance discontinuity.Relative dielectric constant is the measured value of this material with respect to the dielectric constant of ideal vacuum.Relative dielectric constant under the vacuum is 1.00000.This dielectric constant changes according to the material that uses among the given embodiment.For example, usually, the dielectric constant of air is about 1.00059, and the dielectric constant of teflon (polytetrafluoroethylene (PTFE)) is about 2.05, and the dielectric constant of Polyetherimide is about 3.1.

As described in certain embodiments at this, along the length of contactor 100, the dielectric constant of material may change between the conductor.For example, shown in Fig. 1 C, can there be gap 160 in the contact point between contactor 100 and reception structure 150, and it makes and causes dielectric constant to change from the dielectric constant of spacer 120.Gap 160 can be an ambient gas, for example, and air.In order to reduce the 160 pairs of contactor Effect on Performance in gap, by having compliance, length or height that this external conductor 130 can minimum gaps 160.

In certain embodiments, by changing diameter d 1 and/or D1, therefore the influence of the change in dielectric constant of compensate for clearance 160, makes impedance Z keep constant value.In addition, can change the arbitrary surface area of the two, with the variation of compensation dielectric constant.

For the impedance of control contactor 100 along its length, some embodiments of the present invention are set to compliance with external conductor 130, and do not change inside diameter D.That is, some embodiment make external conductor 130 distortion or deflections, and keep conductivity, and can will not give contactor 100 more than minimum or not enough impedance discontinuity.

In addition, in various embodiments, external conductor 130 can be a compliance, so that when contactor 100 contact with structure 150, it can to the conductor 110 of contactor and 130 with the pad 154 of reception structure 150 between skew, deviation or gap, gap compensate.That is, because have compliance, so external conductor 130 can guarantee to contact external pads 158, and center conductor 110 contact center bonding pads 156 are shown in Fig. 1 C.The aspect of complying with of conductor 130 makes and all can realize contacting near center conductor 110 and external conductor 130, and do not need intact or high-precision alignment the between contactor end, center 112 and the external conductor end 132.That is the gaps such as distortion that, comply with 130 pairs of possibility difference thermal expansions of the common skews that exist, the areal deformation that receives structure 150 and/or pads 154, material because of manufacturing tolerance of external conductor between this structure, cause because of breakage compensate.

According to this embodiment, whole external conductor 130 or only its part can be out of shape or compliance.For example, in the embodiment shown in Figure 1A to C, external conductor 130 deforms in the comply with part or the section of complying with or compliant member 140 adjacent with end 132.In other embodiments, along external conductor 130, the deformable segment of external conductor 130 or comply with part and can be positioned at diverse location, perhaps a plurality of positions simultaneously are adjacent to be provided with one or more rigidity or semi-rigid part on end 132 or with end 132.

In certain embodiments, center conductor 110 also be compliance, can be out of shape and/or can deflection.For example, elasticity pin or pogo pin can be used for center conductor 110.

The part 140 of complying with of this equipment is attached on the external conductor 130, perhaps integrates with external conductor 130.Complying with part 140 and external conductor 130 can be individual unit, perhaps is actually individual unit at least.Can reduce like this and shift quantity or along the structure of the signal path of propagating by contactor 100 and be installed to any cable on it or the quantity of the contact point between the structure.Shift minimizing transfer or contact point and can cause reducing impedance discontinuity, otherwise, in this position impedance discontinuity takes place then.

In various embodiments, can remove and comply with part 140, so that replace it.Shown in Fig. 1 C, when contactor 100 contact structures 150, comply with part 140 distortion or deflections, with externally between conductor 130 and the external pads 158, then, all realization contacts between center conductor 110 and center bonding pads 156.

At least in one embodiment, shown in Figure 1B, under its initial nondeterministic statement, comply with the end 112 that part 140 extended to more than or be lower than center conductor 110.End 112, difference location and 132 makes that complying with part 130 contacted external pads 158 before center conductor 110 contacts center bonding pads 156 like this.Guarantee like this between contactor 110 and structure 150 have a few and realize contacting and keeping in touch.

If center conductor 110 is non-compliances, indeformable or indeformable basically, the electrical length of fixed contact 100 then, and also irrelevant with the amount of complying with of complying with part 140, deflection or deflection.

In certain embodiments, with different shown in Figure 1B and the C, end 112 and end 132 can be positioned at different position mutually.Can locate the end of this conductor in every way, keep the difference location simultaneously, so that comply with part 140 contact external pads 158, and also before center conductor 110 contact center bonding pads 156, it can deflection.Other modes of locating this end comprise that end 132 extends to outside the end 112, so that external conductor 130 has bigger compliance, perhaps hold and are positioned at outside the plane or uneven pad mutually.Equally, in other embodiments, compare with end 132, end 112 further extends to contactor 100 outsides, also is used for the pad of inhomogeneous aligning.Inhomogeneous aligning pad can comprise the ladder arrangement, wherein compares with other pads or each other pad, and pad 156 or 158 further extends to structure 140 outsides.

According to this embodiment, comply with part 140 and can on gamut, be out of shape, to cause the skew between contactor 100 and the reception structure 150.Make given contactor 100 can adopt the various different structures that receive like this.

In various embodiments, can change the particular aspects of each parts of contactor 100 and reception structure 150.For example, comply with some embodiment of part 140 in this detailed description.Certainly, those skilled in the art understand, may exist in many other embodiment outside this specifically described embodiment, and they also within the scope of the invention.For example, in other embodiments, show basically or greatly with one heart or coaxial manner is provided with center conductor 110, spacer 120 and external conductor 130, perhaps in other embodiments, they are set with non-concentric manner or with offset manner.Equally, in certain embodiments, can adopt more than one center conductor 110, spacer 120 and/or external conductor 130.In addition, can also change the shape of center conductor 110, spacer 120 and/or external conductor 130.

Additional embodiment of the present invention comprises normally oval-shaped external conductor 130 and spacer 120.Simultaneously externally has the space in the conductor 130.In these embodiments, there are at least two inner conductors 110 that separate along the oval-shaped length of this spacer.In certain embodiments, the layout of inner conductor 110 is that difference is arranged and/or bifilar layout in pairs.

In one or more embodiment, at least one center conductor 110 is compliances, or deformability or deflection, comprise elasticity pin etc.These embodiment fix a center conductor on length, be compliance with the electrical length that defines contactor 100 and (respectively) other center conductors, electrically contact to set up with this reception structure.

Shown in Figure 1A, contactor 100 can also comprise bias component 102 and block or the limiter 104 that is positioned at around the external conductor 130.Bias component 102 can be bias force can be applied to spring or other deformable structures on the remainder of contactor 100 by block 104.In doing so, bias component 102 contactor 100 of can setovering, so that when the contactor deflection, shown in Fig. 1 C, it can be pushed to its not deflected position, shown in Figure 1A and B.

In certain embodiments, facing to the end (not shown) of end 132, unsteady or movably the cable (not shown) be installed on the contactor 100.Like this, the cable of installation can move along with the displacement of bias component 102.

Bias component 102 makes contactor 100 can keep in touch this reception structure, thereby helps to realize being electrically connected between them.In addition, utilize bias component 102, contactor 100 can be regulated, to hold given reception structure or a large amount of different each surperficial all places that receives structure.Utilize the contactor of a series of for example array formats, bias component 102 can make each contactor 100 deflection, to cause the lip-deep variation that receives structure 150.The surface of this reception structure changes can comprise curling, deflection or flexure plane, and these are that manufacturing tolerance produces.

In an illustrated embodiment, deformable component 244 is normally straight crooked around spacer 220, and along the length of each parts 244, with 242 one-tenth fixed angles of base or become fixed angle at least basically.In different embodiment, can be according to comprising the deflection of complying with the required requested number of part 240, the structure that requires coefficient of elasticity, deformable component 244 of complying with part 240, promptly, if the material that thickness, shape etc., compliant member 240 are used exists the various factors that requires deformation quantity and other similar factors of this structure, change the angle of each parts.For each parts 244, can change the angle of parts 244, and in certain embodiments, change the angle of these parts 244 along the length of each parts.Each comprises end 246 deformable component 244.

Shown in Fig. 2 B, in various embodiments, locate deformable component 244, so that parts 244 are positioned at the cylinder that external conductor 230 limits with the remainder of external conductor 230 with aiming at.That is, along the length of parts 244, the center curvature of parts 244 solderless wrapped connection tentaculums 200 is so that as the remainder of external conductor 230, parts 244 keep identical internal diameter and/or radius to the contactor center.

By parts 244 and external conductor 230 are remained on the same cylinder, and diameter d 2 and D2 are remained unchanged, comply with part 240 and keep constant impedances.Eliminate or reduce the performance of impedance discontinuity positive influences contactor 200.Yet, in certain embodiments, can change the shape of parts 244, so that along its length, extend inward into the center of contactor 200 and/or stretch out from the center of contactor 200.

As in this description that contactor 100 is done, for contactor 200, external conductor 230 and to comply with part 240 can also be aforesaid various identical or similarly suitably material arbitrary.In various embodiments, conductor 230 can be an electric conducting material with complying with part 240, so that pass through the signal of telecommunication.

In certain embodiments, this material is deformable and/or flexible, so that this structure is returned not deflected position and/or initial position, perhaps in some cases, at least to deflected position and/or initial position do not return.In certain embodiments, after distortion, comply with part 240 and return fully, perhaps return its not deflected position at least basically.In other embodiments, when deflection, the material deformation of complying with part 240 so that returns and can not reach former beginning and end deflected position to a certain degree.In certain embodiments, part 234 is complied with in configuration, with deformation during complying with part 240 initial deflections, thereby to complying with all further distortion of part 240, sets up or set up the not deflected position of complying with part 240.

As in this description that external conductor 230 is done, can also comply with part 240 from the remainder dismounting of external conductor 230.If take place to disconnect or consume, then can replace easier, more quickly like this and comply with part 240.

Fig. 2 C illustrates and receives the contactor 200 that structure 250 contacts.As can be seen from this figure, when complying with part 240 contact pads 254, it is by deflection.More particularly, not deflection deformable component 244 (shown in the dotted line) contact pad 254, and therefore by deflection, as deflection deformable component 244 '.Deflection member 244 ' with deflection end 246 ' is positioned on pad 258 surfaces.The deflection of deformable component 244 make parts 244 direction Z from its not deflected position move to base 242, and at normally horizontal direction Y, it moves to the surface of base 242 and pad 254.

Deformable component 244 can be improved electrically contacting between pad 258 and the deformable component 244 along pad 258 in Y direction or moving transversely.Note that this moves needs not to be transversely, perhaps needs not to be on the Y direction, and this moves can be on the curved paths or be on cylinder basically.In many cases, in the time of in the conducting surface such as pad 254 and end 246 is exposed to such as the environment of air, they may obtain oxide or such as the coating or the coating of the other materials of dust and dust.This coating may reduce this surperficial conductivity, therefore, may reduce the performance of this equipment or related equipment.In some cases, in order to prevent electrical connection, extensively adopt to produce oxide.Although utilize such as scraping or the method for coating solvent or cleaning agent can be removed this coating from affected surface, common, the timeliness of this operation is strong, and cost is too high, unrealistic or in fact impossible.

Yet embodiments of the invention can be removed coating 259 that is positioned on the pad 258 and the coating 248 that is positioned on the deformable component 244, shown in Fig. 2 C.At initial position or contact point C2, deformable component 244 its each external pads 258 of contact.Then, when complying with part 244 and be compressed with deflection, deformable component 244 moves towards base 242 backward, and the surface by external pads 258.Deformable component 244 has produced the contact-making surface of cleaning coating or has wiped and/or struck off action such as other products of oxide and organic membrane by external pads 258 surfaces this mobile.Can remove the coating 248 of the deflection deformable segment 244 ' of its deflection end 246 ' that is positioned at a C2 ' like this, then, directly contact also has been removed the surface of the external pads 258 of its coating 259.So externally realize better or improved the electrical connection between conductor 230 and the external pads 258, thereby improve the overall performance of contactor 200.

According to this embodiment, can change the erasing move amount and/or strike off actuating quantity.Roughness by one of the deformable component 244 in the contact zone of raising between them, external pads 258 and/or the surface of the two can improve the erasing move amount and/or strike off actuating quantity.Equally, reduce this surface roughness, can reduce this action.In certain embodiments, the low this contactor of contact frequency for the blanking time between being used under the high oxidation environment, using between long and/or contactor and the reception structure, may there be thicker coating, requires the stronger action of wiping or strike off in order to remove their like this.In other embodiments, wipe and/or strike off action for what be used under the weak oxide environment and/or the higher contactor of frequency of operation, can adopt weakening.Conversely, wipe a little less than and may prolong the life-span that this complies with part and each pad thereof.The physical dimension of deformable component 244 can also determine to wipe length, and therefore increases or reduce the amount of wiping.Erasing move amount and/or strike off actuating quantity and depend on that also 200 pairs in contactor receives the power that structure 250 applies.

As shown in the figure, wiping distance is positioned between a C2 and the C2 '.

In certain embodiments, gold is used for deformable component 244 and/or adopts gold on pad 258, can significantly reduce wear extent, thereby prolong the life-span of contactor 200.

In certain embodiments, because the path-length of current spread, the spirality of deformable component 244 can provide higher inductance.Like this, spirality deformable component 244 can be used as spiral inductor.Yet, arrive less than columnar rotation by length restriction around external conductor 230 with deformable component 244, this inductance value is enough little, thus this external conductor in fact as if as or regard deformable component 244 as and externally realize that basically straight line (along the z axle) is connected between conductor 230 and the reception structure 250.For inductance, this can utilize equation E4 to represent:

The 388th page equation [6.3.1.1] at the Transmission of Brian C.Wandell Line Handbook shows this equation, and is for reference at this full content of quoting Transmission Line Handbook.Wherein N is the number of turns around this equipment.As can be seen, when N enclosed less than one, inductor was similar to direct connection.

Certainly, those skilled in the art understand, may have many other embodiment outside the embodiment that specifically illustrates, and they within the scope of the invention.For example, in other embodiments, can center conductor 210, spacer 220 and external conductor 230 be set, perhaps in other embodiments, they be set with non-concentric manner or the mode that departs from mutually in basically or common concentric or coaxial mode.Equally, in certain embodiments, can adopt more than one center conductor 210, spacer 220 and/or external conductor 230.In addition, can change the shape of center conductor 210, spacer 220 and/or external conductor 230 respectively.

At the end (not shown) facing to this reception structure 350, contactor 300 can be affixed to the cable (not shown).The cable that is added can be a coaxial cable, and can float, and therefore, this cable can move with the contactor displacement.

In certain embodiments, center conductor 310 can not be out of shape, and perhaps can not be out of shape at least basically, and therefore, it provides the contactor 300 of the particular electrical length of qualification.The compliance of complying with part 340, distortion and/or the deflection of the length of the qualification of contactor 300 and external conductor 330 is irrelevant, will be described further at this.Like this, the compliance of complying with part 340 changes and does not influence the electrical length of contactor 300.

Comply with part 340 and comprise deformable component or bar or the pawl 344 that extends to outside (as shown below) from base 342.At deformable component connector 343, deformable component 344 contact bases.The shape of the deformable component 344 by this embodiment of bend fixing so that distortion, reduces simultaneously or minimizes length by the current path of deformable component 344.In addition, form this deformable component,, carry out and wipe or strike off action with when contacting external pads 358.The shape of shown deformable component only is to realize any one of different shape of the embodiment of the invention of above-mentioned aspect.

In an illustrated embodiment, the shape of typing deformable component 344 is so that parts 344 deform on more than one direction.Different with parts 244, when this base stretched out, parts 344 were not straight usually at them.Parts 344 stretch out from base 344 at first direction, then, curve with curved shape and second direction.In different embodiment, can be according to being included in comply with on each direction that part 340 can form require deflection, comply with the structure that requires coefficient of elasticity, deformable component 344 of part 340, promptly, if the material that thickness and shape etc., compliant member 340 adopt exists the various factors that requires deformation quantity and other similar factors of this structure, change the angle and the curve of deformable component 344.Change angle and curve for each parts 344.Each comprises end 346 deformable component 344.

Shown in Fig. 3 B, aim at location deformable component 344 with the remainder of external conductor 330, so that parts 344 are positioned at the cylinder that external conductor 330 is determined.That is, along the length of parts 344, the center curvature of parts 344 solderless wrapped connection tentaculums 300 is so that as the remainder of external conductor 330, parts 344 keep identical inside diameter D 3 and/or radius to the contactor center.

Identical with parts 244, remain on the same cylinder by making parts 344 and external conductor 330, and make diameter d 3 and D3 keep identical, comply with part 340 and keep constant impedance.Keep this impedance to prevent any resistance discontinuity, otherwise, the performance of contactor 300 may be influenced.

Certainly, in other embodiments, the shape of the deformable component of can finalizing the design 344, so that extend inward into the center of contactor 300 and/or stretch out from the center of contactor 300, and the cylinder of relaxed registration external conductor 330.

As at this to

contactor

100 and 200 descriptions of being done, contactor 300 has its external conductor 330, and its to comply with part 340 can be aforesaid various identical or similarly suitably material is arbitrarily.In certain embodiments, conductor 330 can be electric conducting material or semi-conducting material with complying with part 340, so that the signal of telecommunication passes through or realizes that the Electricity Federation is logical.

Part 240 is identical with complying with, and in certain embodiments, this complies with part 340 can be deformable and/or flexible, and with after deflection, it returns its not deflected position or initial position, and perhaps deflected position or initial position do not return to it at least.This returning can be to return or return fully basically former beginning and end deflection fully, perhaps in certain embodiments, is in less position because of deformation.During initial deflection, this complies with part 340 can deformation, with all further distortion to it, sets up the not deflected position of complying with part 340.

Identical with other embodiment, can dismantle this and comply with part 340, so that displacement and acceleration displacement easily.

Fig. 3 C illustrates the contactor 300 of this reception structure 350 of contact.As can be seen, when complying with part 340 contact pads 354, it is by deflection.More particularly, not deflection deformable component 344 (shown in the dotted line) contact pad 354, and therefore by deflection, as deflection deformable component 344 '.Deflection member 344 ' with deflection end 346 ' is positioned on pad 358 surfaces.The deflection of deformable component 344 make parts 344 direction Z (shown in vertical direction) from its not deflected position move to base 342, and at normally horizontal direction Y, it moves to the surface of base 342 and pad 354, perhaps usually and this cylinder tangent.

Deformable component 344 can be improved electrically contacting between pad 358 and the deformable component 344 along pad 358 in Y direction or moving transversely.Note that this moves needs not to be transversely, perhaps needs not to be on the Y direction, and still, this moves can be on the curved paths or be on cylinder basically.In many cases, in the time of in the conducting surface such as pad 354 and end 346 is exposed to such as the environment of air, they may obtain the coating or the coating of oxide, organic membrane or other materials.This coating may reduce this surperficial conductivity, therefore, may reduce the performance of this equipment or related equipment.In some cases, in order to prevent electrical connection, extensively adopt to produce oxide.Although utilize such as striking off or the method for coating solvent or cleaning agent can be removed this coating from affected surface, common, the timeliness of this operation is strong, and cost is too high, unrealistic or in fact impossible.

Yet embodiments of the invention can be removed coating 359 that is positioned on the pad 358 and the coating 348 that is positioned on the deformable component 344, shown in Fig. 3 C.At initial position or contact point C3, deformable component 344 its external pads 358 separately of contact.Then, when complying with part 344 and be compressed with deflection, deformable component 344 moves backward to base 342, and the surface by external pads 358.Make this contact point move to contact point C3 ' like this.Deformable component 344 has produced the contact-making surface of cleaning coating or has wiped and/or struck off action such as other products of oxide and organic membrane by external pads 358 surfaces this mobile.Can remove the coating 348 of the deflection deformable segment 344 ' that is positioned at its deflection end 346 ' like this, then, directly contact also has been removed the surface of the external pads 358 of its coating 359.So externally realize better or improved the electrical connection between conductor 330 and the external pads 358, thereby improve the overall performance of contactor 300.

According to this embodiment, can change the erasing move amount and/or strike off actuating quantity.Can improve the erasing move amount equally and/or strike off actuating quantity by the roughness that improves contact surface.Reduce this surface roughness, can reduce this action.As mentioned above, desired erasing move amount can depend on surrounding environment, use amount and other factors.The physical dimension of deformable component 344 can also determine to wipe length, and therefore increases or reduce the amount of wiping.Erasing move amount and/or strike off actuating quantity and depend on that also 300 pairs in contactor receives the power that structure 350 applies.

As shown in the figure, wiping distance is positioned between a C3 and the C3 '.

Shown in Fig. 3 C, the shape of deformable component 344 makes the contraction in length by the path P3 of the electronics of deformable component 344 migrations.Because the potential route that electronic selection is the shortest, as shown in the figure, so they are with straight as far as possible direct path migration.From base 342 extensions the time, with the shape of first direction typing deformable component 344, then, this deformable component 344 is returned, and in other direction bendings, has under the situation of some deflections, and this path P3 is straight basically.That is, in fact path P3 cuts the bight that produces by the curve that changes deformable component 344.In certain embodiments of the invention, can change the given shape of path P3 according to the shape of parts 344.

Because path P3 is straight relatively, even and exist, also have very little swing, so can minimize inductance value, perhaps eliminate or eliminate basically inductance.As shown in the figure, path P3 is enough little around the cylindrical rotation amount of external conductor 230, can prevent that basically inductance from existing.Promptly, in such an embodiment, even exist, this rotation amount is also much smaller than single swing, so that for inductance, 344 of this deformable component realize between base 342 and pad 358 that directly (along z axially down, the effect of Lian Jieing as shown in the figure) perhaps looks directly to be connected with pad 358 as base 342.

As mentioned above, in order to obtain to improve the contactor of performance, require to have the shortest migration electrical length by the electronics of external conductor.Have at center conductor under the situation of direct straight electron transfer path, at the difference or the Δ that obtain on this external conductor between the electric path length that the shortest electric path length will minimize inner conductor and external conductor.Conversely, can minimize like this time difference of electronics by each path migration.

Electronics may produce discontinuity by the range difference or the time difference of inner conductor and external conductor migration, and this may influence the performance of contactor.Along with frequency raises, this discontinuity is big more to Effect on Performance.For example, for the embodiment of the signal in carrying 30 to the 40GHz scopes, even the little Δ of the electric path length between inner conductor and the external conductor also has opposite effects to performance.

In certain embodiments, the discontinuity that produces with respect to the variation of impedance, because the discontinuity that the Δ of the electric path length of this conductor produces may produce secondary influence, yet, for application-specific, for example, very high signal frequency, improve performance for system, can minimize these secondary influences.

In the embodiment shown in Fig. 3 A to C, in complying with part 340, reduce electric path length or path P3, with the Δ of the power path that minimizes this conductor.Minimize Δ like this and can reduce discontinuity, therefore, improve performance.The path of shortening is provided with that its structure can fully be out of shape so that this external conductor 330 has the deformable component 344 of compliance.In addition, change the shape of this deformable component 344, carrying out erasing move, thereby improve electrically contacting between the pad 358 of this reception structure 350.

In some embodiments of the invention, the shape that changes this deformable component can change the address of the contact point between this deformable component 344 and this reception structure 350.Conversely, the position of contact point C3 can change length and the transverse movement between this deformable component 344 and this pad 358 and the action of striking off that is realized of path P3.

Can change end 346 and contact point C3 ad-hoc location according to embodiment with respect to connector 343.In certain embodiments, as shown in the figure, locate end 346 like this, make contact point C3 just be positioned at the side of connector 343.In other embodiments, this contact point can be located immediately at following, back or near other positions this.

In certain embodiments, with gold or gilding is used for deformable component 344 and/or adopt gold or gilding on pad 358, can significantly reduce wear extent, thereby prolong the life-span of contactor 300.Other possible materials comprise: palladium, rhodium and other non-oxide materials known now or that develop afterwards.

Those skilled in the art understand, may exist can reduce or the minimization circuit electrical path length, and having other of the good geometry that obtains the compliance that requires and contact performance simultaneously may shape and the deformable component 344 of configuration.In addition, in other embodiments, can center conductor 310, spacer 320 and external conductor 330 be set, perhaps in other embodiments, they be set with non-concentric manner or the mode that departs from mutually in basically or common concentric or coaxial mode.Equally, in certain embodiments, can adopt more than one center conductor 310, spacer 320 and/or external conductor 330.In addition, can change each shape in center conductor 310, spacer 320 and/or the external conductor 330.

In some embodiments of the invention, this contactor has the part of complying with, and this is complied with part and has the deformable component that is fixed to intersection figure, cross figure and/or " X " figure.These shapes allow distortion, and can reduce or minimize the length of electronics path when improving signal shielding.The electric pathway that shortens can reduce because the discontinuity that the difference between the electronics path-length of inner conductor and external conductor produces.

As shown in Figure 4, contactor 400 comprises center or inner or first conductor or center pin or signal pipe line 410, spacer or insulator 420 and outside or second conductor or screen or loop 430.Because can be out of shape, so this external conductor 430 is compliances, and it comprises at least adjacent with end 432 part or the section of complying with or the compliant member 440 complied with.The contact pad of its contact pad (not shown) and

structure

250 and 350 similarly receives structure or device interface board or DIB (not shown) can hold contactor 400.

At an end (not shown) of opposed end 432, contactor 400 is affixed to the cable (not shown).The cable that is added can be a coaxial cable, and can float, and therefore, this cable can move with contactor 400 displacements.

In certain embodiments, center conductor 410 can not be out of shape, and perhaps can not be out of shape at least basically, and therefore, it provides the contactor 400 of the particular electrical length of qualification.The qualification length of contactor 400 and the compliance of complying with part 440, distortion and/or the deflection of external conductor 430 are irrelevant, will be described further at this.Like this, the compliance of complying with part 340 changes and does not influence the electrical length of contactor 400.

Comply with part 440 and comprise deformable component or bar or the pawl 444 that extends to outside (extending as shown in the figure) from base 442 with intersection figure or " X " figure downwards.By bending, this deformable component 444 allows distortion, and forms this deformable component 44, so that when contact external pads (not shown), carry out erasing move or strike off action.
