Description

Combined electrical plug and have the plug-cable assembly of combined electrical plug
The field of the invention
The present invention relates generally to electrical fitting, more particularly, relate to near-end crosstalk (" the NEXT ") performance that provides consistent and/or the multiposition combined plug of TOC (terminating open circuit) performance, consistent NEXT performance promptly have same design plug lead between NEXT value basic identical, the TOC performance of unanimity promptly have same design plug lead between the TOC value basic identical.The TOC performance is relevant with the capacitive character near-end crosstalk, so comprised the TOC performance with the related NEXT performance of capacitive character and inductive cross-talk.
According to its structure, can be used as 5 grades, 5E level or 6 grades of plugs according to combined plug of the present invention.
The invention still further relates to the assembly of combined plug and multiconductor cable, this cable one end is by this plug terminating, and the other end is by another plug or another electrical fitting terminating.
Background of the present invention
Now the data communication network of development can make information flow be transferred to more user with transmission rate faster.But in much easier cross-talks of data to the transmission of data communication cable high speed, this can produce adverse influence to the processing of transmission data.When signal energy accidental from a signal to " string " to another signal to the time cross-talk will take place.Signal from one group of lead string to or be connected to another the group lead some position may be arranged in: 1) connector of transfer station or internal circuit, be known as " near-end crosstalk ", 2) in the connector or internal circuit of receiving station, be known as " far-end crosstalk ", perhaps 3) in the interconnecting cable.
For the telecommunication connector that the FCC that is generally known as combined connection component (federal information association) partly stipulates among the inferior F of portion of (part) 68.500, the special trouble of near-end crosstalk (" NEXT ").The EIA/TIA of ANSI (ANSI) (electronics/telecommunication TIA) has announced and has been used for carrying out the electrical code that near-end crosstalk is isolated at Network connecting member, can not influence the overall performance of general use unscreened twisted-pair feeder (UTP) interconnected hardware in LAN (local area network (LAN)) system to guarantee connector itself.EIA/TIA5 level electrical code has been stipulated for the minimum near-end crosstalk insulation of cross tie part when speed is up to 100MHz of using at 100 ohm of unshielded twisted pair ethernet types.
General plate connector has a housing, and this housing has the cavity that size is suitable for admitting a combined plug within it, and this cavity is provided with a plurality of spring contacts of of hanging, the similar a plurality of contact terminals in the combined plug that this spring contact correspondence is mated.This combined plug is admitted discrete, isolate, stranded or solid conductor, and these conductors are arranged in the conductor that is formed on insulation shell and admit passage or groove.Flat, foliated metallic terminations is inserted in the single groove of vertically locating in the housing side by side, and its contact portion extends to conductor and engages.When plug is inserted in the plate connector, the part of hanging the associated terminal in the part engagement plugs of the terminal in the socket.
When plug is in not engagement state, promptly when not having electric current to flow through plug, by measuring the Near-End Cross Talk Loss that does not shield between the twisted conductors, the characteristic of 5 grades of plugs must be verified the FCC standard that meets ANSI/TIA/EIA-568-A.This measurement is known as " terminating open circuit " or TOC test sometimes.
In the 8 positions plug, contact and twisted wire from left to right are numbered as 1 to 8 when contact face makes progress, it is right that lead 4 and 5 forms No. 1 signal, be electrically connected in a circuit when being their runnings, it is right that lead 1 and 2 forms No. 2 signals, it is right that lead 3 and 6 forms No. 3 signals, and it is right that lead 7 and 8 forms No. 4 signals.In this case, to six different twisted conductors/line combination carrying out TOC test, what promptly signal was right is combined as 1 and 2,1 and 3,1 and 4,2 and 3,2 and 4 and 3 and 4.
In order to carry out the TOC test, use device shown in Figure 1.The resistance 10 of one 100 Ω and the test lead of 100 Ω 12 (they are connected to the balanced-to-unblanced transformer 14 of wideband at this) in parallel are tested NEXT by network analyser 16.The NEXT loss that records during 100MHz must be in the scope shown in the table 1.
Table 1 lead is to NEXT loss 1 and 2 〉=55dB1 and 3 〉=40dB1 and 4 〉=55dB2 and 3 〉=45dB2 and the 4 〉=55dB3 and the 4 〉=45dB of combination test plug during 100MHz
In addition, to making up 1 and 3, the difference between the NEXT loss that records when NEXT loss that records during 100MHz and 10MHz must be 20 ± 0.5dB for lead.Require to comprise to making up 1 and 3 other TOC for the lead of test plug: when 100MHz at least the NEXT loss of one of them test plug must be in 〉=40.0dB is to the scope of＜40.5dB; When 100MHz at least the NEXT loss of one of them test plug must be in 〉=40.5dB is to the scope of＜41.5dB; And when 100MHz at least the NEXT loss of one of them test plug must be in 〉=scope of 41.5dB in.
Traditional combined plug has at independent conductor to be admitted in the passage in order to admit one or more carrier bars of conductor.The use of carrier bar is of value to the inner conductor electric capacity in the control plug.Fig. 2 illustrate ten 8 positions combined plugs for same design at lead to making up the TOC value that records between 2 and 4, specifically, this plug is a RJ45 connector, it has two carrier bars of the zinc-plated standard UTP cable of 24AWG that terminating Lucent Technologies makes.As shown in Figure 2, for the 8 positions combined plug with same design, the variation of the TOC value of (compare test plug 1 and 10) can be up to 40dB between the plug.Owing in the main body of plug, promptly the lead in plug is admitted the relative random arrangement that does not shield multiple twin (UTP) conductor in the passage, this causes the electric capacity between conductor to change a little on this changing unit degree.
A method that reduces the plug inside capacitance of conductor is by being offset adjacent conductor.The example of the type plug is disclosed in the 5th, 628, in No. 627 United States Patent (USP)s people such as () Rohrbaugh, wherein all conductors be arranged between the upper and lower every two planes row in.The conductor of this biasing helps to reduce the internal capacitance of plug, but can not cause stable TOC value for the plug with same design.
In order to obtain consistent TOC value, in another trial of doing for the electric capacity of stablizing in the RJ45 connector, three plugs 20 respectively are provided with four carrier bars 22 (Fig. 3) for the plug with same design.This plug is initially the standard RJ45 connector that this end water (stewart) connector system house makes, but be modified as and have four carrier bars, and when test terminating one Berk-Tek Lan-Mark-350 cable (except as otherwise noted, described here all TOC tests in use identical cable).Employed four carrier bars of fixing internal capacitance of conductor are in the length of plug body.Then TOC is carried out in combination and measure, to determine the degree of stability of TOC value for each lead.As shown in Figure 4, use the TOC value that records on three plugs of four carrier bars for the variation between plug and plug less than 4dB.
For four carrier bar plugs shown in Figure 4, although the variation of the TOC value that records between plug and the plug less than the 5 grades of 8 positions combined plugs of standard that use two carrier bars, lead does not always have and meets the TOC value that TIA/EIA-568A requires making up 1 and 3.In fact, the minimum TOC value that obtains in three plugs that lead is tested making up between 1 and 3 is 39.8dB.But, are 40dB (seeing Table 1) for lead to the requirement of 1 and 3 minimums, so the plug of these remodeling can't pass the TOC test according to ansi standard EIA/TIA-568-A.
About the lead of plug between NEXT value (measurement of capacitive character and inductive cross-talk), found that being changed on the small part degree of NEXT value between the plug of same design is because the random arrangement of eliminating the UTP conductor under the body in the distortion of plug causes.Promptly, distortion in the general plug eliminate body before the shielding of removing cable and just in the placed channel that conductor is inserted in the plug (being in the carrier bar of plug) engage in a position with the cable of shielding before, therefore, the UTP conductor with arbitrarily, the distortion that is arranged in the cable of at random mode eliminates under the body.Also find because the random character of arranging under the body is eliminated in the distortion of conductor in cable, lead between the TOC value also can change.In this, Figure 15 shows ten all leads of different plugs of 5 grades of plugs of RJ45 type that present assignee is made to the NEXT value of combination (for example, lead is represented by 45-12 2 to lead 1) test and the result of TOC value.The NEXT value of measuring is " removal is mingled with (de-embedded) " NEXT value,, measures the cross-talk of a matching plug and socket that is, has deducted the cross-talk of socket, so this result value only is the cross-talk that the structure by plug causes.Figure 16 is based on the data in Figure 15 table, removes the table of maximum, minimum value and the changing value of the NEXT value be mingled with.As shown in figure 16, the excursion (△) of removing the NEXT value be mingled with is 7.1dB to 27.6dB.Figure 17 is the table based on maximum, minimum value and the changing value of the data in Figure 15 table, TOC value.As shown in figure 17, the excursion of TOC value (△) is 5.9dB to 20.9dB.Therefore because the variation of NEXT and TOC value can have a negative impact to the running performance of plug, it will be useful reducing to remove the NEXT value that is mingled with and the intensity of variation of TOC value.

Plug with reference to Fig. 5-7 and Figure 11-14C description can be used to an end of terminating multiconductor cable, and the other end of this cable terminates in similar plug or another combined connection component.Form a plug cable assembly thus.
Above-mentioned embodiment according to plug of the present invention has consistent TOC performance.But, when Development of Communication, no matter 5 grades, 5E level, total still 6 grades plug to have consistent NEXT performance be favourable.
Second embodiment according to plug of the present invention is illustrated among Figure 18-26, and has consistent TOC performance and NEXT performance.In the present embodiment, plug 140 has a housing 142 and the carrier bar 144 that insulating material is made.Housing 142 has the size of standard RJ45 connector, and has a latch 146 of giving prominence to from lower surface 148.Housing 142 also has parallel, the separated longitudinal extension terminal receiving channel 150 and the vertical cavity 154 below the rear surface 156 of housing 142 extends inwardly to terminal receiving channel 150 at a front end place that is formed on upper surface 152 middle shells 142.The rear portion 158 of cavity 154 has the cross section of essentially rectangular, and the front portion 160 of cavity 154 is configured to the front end 162 that is suitable for admitting carrier bar 144, and this carrier bar 144 has the conductor or the lead of the cable of the plug terminating that is inserted on it.Carrier bar 144 preferably longitudinally stretches with cavity 154.The rear portion 158 of cavity 154 156 inwardly is tapered from the rear surface.Upper surface 152 extensions of body 164 from housing 142 are eliminated in one distortion, and have extension a lower surface approaching or that extend in the rear portion 158 of cavity 154.
Carrier bar 144 be with the insulating material manufacturing and have lead and admit passage 166, two each four passage of row are arranged in an illustrated embodiment.Passage 166 is staggered relative to each other and be suitable for admitting the lead of different size.Passage 166 is open so that easily insert lead 168, and is configured to and is convenient to the fixing lead 168 that keeps in the passage 166.More particularly, each passage 166 is formed by the curved surfaces 170 of a longitudinal extension, and curved surfaces 170 has formed a support (Figure 22) of receivability lead 168.Between adjacency channel 166, form projection 171 thus.The projection 171 that is formed on down between the passage 166 among the row was clipped head before the leading edge of carrier bar 144, in the front end 172 of carrier bar 144, to form a step, wherein down the passage 166 among the row is defined by a lower surface, and the passage 166 in the row of going up is defined by opposite side surfaces.
The size of the front end 172 of carrier bar 144 makes in its front portion 160 that can be inserted into cavity 154 fully, and the size of the rear end 173 of carrier bar 144 makes in its rear portion 158 that can be inserted into cavity 154 fully.The front portion 160 of cavity 154 provides relative upper and lower surface 174,176, when being inserted into carrier bar 144 in the plug casing 142, lead 168 among the following row slides along upper and lower surface, withstand the front end of cavity 154 up to them, when being inserted into carrier bar 144 in the plug casing 142, lead 168 among the last row slides along opposite side surfaces 178 and upper surface 180, withstands the front end (Figure 26) of cavity 154 up to them.Upper surface 176,180 has a slit, and the contact terminal is passed this slit to pierce through lead 168 (Figure 26).
One key character of carrier bar 144 is exactly that it has one " hinge ", can rotate the rear portion of carrier bar 144 relative to the front portion.In case carrier bar 144 is inserted in the cavity 154 and its front portion when being fixed in the cavity 154, just can realize this motion.More particularly, carrier bar 144 has the alignment slot 184 that is arranged in projection 171 and 145 both sides, edge.The front end 172 of the rear portion 186 relative carrier bars 144 of the rear end 173 of the existence permission carrier bar 144 of slit 184 and the front portion 188 of rear end 173 produce crooked.Below discussing must crooked reason.
By carrier bar 144, the entire portion of every lead 168 is positioned at accurate precalculated position in the plug casing 142, comprises the position that is under the distortion elimination body 164.In this way, can avoid the random arrangement of lead 168 any parts in the plug 140.Every lead 168 also is in preposition by the position of this part that terminal 182 engages.In according to plug of the present invention, the part that requires lead to eliminate between body 164 and the terminal 182 in distortion at least is secured in place.
Be connected fasteningly in order to make cable 190 and plug 140 eliminate body in the face of distortion, shown in Figure 24-26, the part of the cable cover(ing) 192 of cable 190 covers on the rear portion 186 of rear end 173 of carrier bar 144.This can obtain by cutting cable cover(ing) 192 certain distances, this distance needs with the length of plug terminate cable 190 equally long with lead 168 at least, then cut the notch portion of cable cover(ing) 192, stay the cable cover(ing) 192 of q.s, with on the rear portion 186 of the rear end of carrier bar 144 and below extend to slit 184.Slit 184 is formed on the position on the carrier bar 144, therefore makes distortion eliminate body 164 and is between the rear end and slit 184 of carrier bar 144.
In order to be formed in the cable cover(ing) 192, to expose a segment length of long lead 168 as the length of carrier bar 144 at least with 190, two relative vertical slits of plug 140 terminate cables.As traditional mode, usually multiple twin lead 168 corresponding its labels in cable are by untwisted and compress into the passage 166 of carrier bar 144.The end of lead 168 is stretched out the front end that the part of carrier bar 144 cut with carrier bar 144 and is flushed.Cut the slit part of cable cover(ing) 192, make sheath only extend to slit 184, as shown in figure 25.During carrier bar 144 with slit part of cable cover(ing) 192 is inserted into cavity 154 in the housing 142 along avris, withstand the front end (Figure 26) of cavity 154 up to the front end of carrier bar 144.Because the size of cavity 154 is suitable for admitting carrier bar 144, below carrier bar 144, there is not clearance, and on carrier bar 144, have some clearances, when being inserted into carrier bar 144 in the cavity 154, the slit that is positioned at the cable 192 under the carrier bar 144 partly causes the rear portion 186 of the rear end 173 of carrier bar 144 to be bent upwards, and its bending is carried out (Figure 26) by slit 184.Terminal 182 in the terminal receiving channel 150 in the housing 142 (seeing Figure 24 and Figure 26) then is pressed in the lead 168, with the insulating barrier that pierces through lead 168 and engage metal core in it.But therefore terminal 182 pre-determined bit only need they are compressed into lead 168 in groove 150.
After this, inwardly the pushing distortion is eliminated body 164 or is set the slit part that covers the cable cover(ing) 192 on the rear portion of carrier bar 144 for joint, thus be connected (the seeing Figure 24) of attached cable 190 and plug 140.The inside pushing that body 164 is eliminated in distortion causes the rear portion 186 of the rear end 173 of carrier bar 144 to be pressed downward facing to the lower surface of cavity 154, the rear portion 186 that reduces rear end 173 thus and the front portion 188 of rear end 173 and and front end 172 between angle (comparing Figure 26 and Figure 24).Because the existence of cable cover(ing) between the lower surface of rear portion 186 and cavity 154, rear portion 186 is not in same plane with anterior 188.
The NEXT between the plug of same structure and the variation of TOC value have been reduced to have in the location that the lead 168 in the precalculated position under the body 164 is eliminated in distortion.In traditional plug, the lead random arrangement is being out of shape the position of eliminating under the body, and when distortion elimination body was inwardly compressed into cable, the lead in the cable kept this to be provided with at random, even lead is easy to increase mobile at random.It is inconsistent that this of lead is provided with the NEXT and the TOC value of the plug that causes having same design at random.
Special advantage according to plug casing 142 of the present invention and carrier bar 144 structures is the cable that available plug 140 terminating have different-thickness sheath and different-diameter lead.For lead, the size of passage 166 is set at the lead that is equal to or greater than relatively large diameter, so also can locate within it than the lead of minor diameter.For the sheath of different-thickness, the height setting at the rear portion 158 of cavity 154 is greater than the height of carrier bar 144 and is the twice of relatively large thickness of cable sheath.Thus, the cable that has thin cable cover(ing) and insulating sleeve can be used to around carrier bar, and the top of body with the junction cable sheath is eliminated in distortion thus, and being connected of attached cable and plug 140 thus.
Plug among above-mentioned Figure 18-26 can be used to an end of terminating multiconductor cable, and the other end of this cable can be with similar plug or other combined connection component terminating.Form one plug-cable assembly thus.
Referring to Figure 27-29, Figure 27 shows the NEXT that the removal of the plug sample with analog structure shown in Figure 18-26 is mingled with and the chart of TOC value.The plug of test has two carrier bars of the same types of use in RJ45 connector is tested, to the results are shown in (only used a carrier bar in these tests, cable is eliminated the body joint by distortion thus) among Figure 15-17 of RJ45 connector test.In plug with two carrier bars, second carrier bar is placed near first carrier bar, first carrier bar of traditional form is positioned at the front portion of the cavity under the terminal receiving channel, and therefore distortion elimination body will engage the cable cover(ing) that has slit on this second carrier bar.Although the structure of the plug of describing with reference Figure 18-26 is different, believe this structure have with according to plug of the present invention identical NEXT and TOC performance.
The plug terminating Berk-Tek Hyper-Grade Cat 5 utp cabling cables of test.Figure 28 is maximum, minimum value and the changing value of the NEXT value that is mingled with in the removal that 12 different plugs are tested.Any as can be seen two leads between variation (△) scope of NEXT value be 1.36dB to 4.94dB.Figure 29 is maximum, minimum value and the changing value of identical plug TOC value.As shown in figure 29, any two leads between variation (△) scope of TOC value be 2.07dB to 6.21dB.These changing values are significantly less than the changing value of RJ45 connector, and the test result of the NEXT of RJ45 connector and TOC value is listed in (as discussed above) among Figure 15-17.
Referring to Figure 30-33, below description had a carrier bar and present another embodiment of the combined plug that improves the NEXT performance.In this embodiment, plug 200 has a housing 202 and the carrier bar 204 (Figure 30) that insulating material is made.Housing 202 have from the outstanding latch 206 of lower surface, be formed on front end in the upper surface parallel, separate, the terminal receiving channel 208 of longitudinal extension, be formed on the vertical cavity 212 that the lead at front end place is admitted passage 210 and extended inwardly to passage 210 from the rear surface.Each passage 210 communicates with each groove 208, and cavity 212 communicates with all passage 210.Cavity 212 is configured to and is used for admitting carrier bar 204.Passage 210 is arranged to special pattern, below will be described.
Carrier bar 200 is formed with eight conductors being arranged to special form and admits passage 214, so that improved NEXT performance to be provided.Specifically, two passages are arranged on top, are designated as a row of the substantially flat of R1, six passages are arranged on the bottom, are designated as a row of the substantially flat of R2, and the passage 214 in the row of going up is in position 3 and 6 thus, and the passage 214 in following the row is in position 1,2,4,5,7 and 8 (Figure 32).Row R1 and R2 are parallel to each other substantially, and preferably parallel with the parallel upper and lower surface of carrier bar 200.Passage 214 also preferably with housing 202 in passage 210 basic coaxial lines.
For terminate cable 218, an end of cable 218 is not established sheath, and stranded lead is to being separated and being inserted into the rear portion of the respective channel 214 in the carrier bar 204.In carrier bar 204, push away this lead forward, stretch out up to the front end of its part from carrier bar 204.Then lead is cut into the front surface of carrier bar 204 and flushes, carrier bar 204 is inserted in the cavity 212 of housing 202 then.Push ahead this lead, its part is entered in the passage 210 in the housing 202.Be placed on contact terminal 216 in the groove 208 of housing 202 in advance and be pushed downwards in the lead in the passage 210, and pierce through its insulating barrier, form thus and be electrically connected with the bonded conductor core.On the housing 202 one distortion is eliminated body 220 and is pressed in the part of the cable 218 in the cavity 212, to be fixed on the housing 202.
In case the lead of cable 218 is through on the carrier bar 204, those leads that are in the lead of position 3 and 6 and are in other positions can cause reducing of cross-talk because of being separated from each other.
Find, lead in the plug 200 is 33.69dB to the NEXT value of 45 and 36 (1 and 3), plug 200 has carrier bar 204, and carrier bar 204 has shown in figure 32 the passage 214 that is provided with, and this is better than having the right NEXT value of same wire in the plug of traditional carrier bar.
Figure 33 shows second cutaway view of the carrier bar of use in plug 200, and it is denoted as 204 '.Carrier bar 204 ' and carrier bar 204 between the main distinction be that the passage 214 at position 3 and 6 places is bigger apart from R2 row's distance, wherein the passage 214 at position 1,2,4,5,7 and 8 places is oriented to make the lead at the lead at position 3 and 6 places and position 1,2,4,5,7 and 8 places to separate farther (D2＞D1).
Although two row's passages have been shown in carrier bar, the passage more than two rows also can be set, as long as the passage of admitting running ground to form the right lead of a circuit is arranged in same row, this row and other leads are residing respectively arrange different.
Find, have the carrier bar 204 that has as shown in figure 33 the passage 214 that is provided with ' plug 200 in lead be 36.21dB to the NEXT value of 45 and 36 (1 and 3), this is better than having the right NEXT value of same wire in the plug of traditional carrier bar.And, find that also the separating distance between the lead plane of living in influences the NEXT performance.
In the carrier bar lead admit the location of passage and shown in Figure 32 and 33 in the plug position of passage can be used for any carrier bar described here and plug, also can be used for other multiple carrier bar and plugs.For example, the admittance of the lead of carrier bar shown in Fig. 5-7 passage can be arranged to the appearance shown in Figure 32 and 33.
Although the carrier bar that is illustrated in Figure 32 and 33 has eight passages, use the principle of the invention described above, also can use carrier bar with different number passages.
Obviously, according to the above discussion, the present invention can carry out various remodeling and variation.It is accordingly to be appreciated that other embodiment of the present invention according to the above discussion also are feasible.For example, for the embodiment among Figure 18-26, need point out that disclosed single carrier bar only is to guarantee that lead is in a kind of mode that precalculated position under the body is eliminated in distortion.Also should be considered as being within the scope and spirit of the present invention in order to other modes that lead remained on the predetermined fixed position under the distortion elimination body.And the carrier bar that roughly extends jointly with the cavity of plug casing is a preferred embodiment.In order to obtain some advantage of the present invention, carrier bar relative deformation is at least eliminated the body extension, and the lead of stationary positioned on carrier bar eliminated its set positions under the body, to avoid the random organization of lead in the plug in distortion thus.At this, carrier bar is not to extend jointly with the cavity in the plug.
