Abstract
The present invention relates to a terminal block for high transmission rates in telecommunications and data processing. The terminal block has a plastic body with at least one row of chambers for insulation displacement contact elements. Slots for shield plates are disposed in transverse walls between the chambers, and extend with axes parallel to the walls. The object of the invention is to provide a terminal block wherein by the configuration of specially-shaped shield plates, an effective reduction of crosstalk and a substantial simplification of assembly of the shield plates and of the cable wires at the insulation displacement contact elements are guaranteed. This is achieved by disposing the chambers of a terminal unit in the plastic body at the smallest possible distance d to each other, and by providing the slots for receiving the shield plates in the transverse walls between adjacent terminal units, the slots extending from a lower side of the plastic body. The distance d between the chambers of a terminal unit are appreciably smaller than the distance D between the chambers of adjacent terminal units.

21 ~2460 TERMINAL BLOCK FOR HIGH TRANSMISSION RATES
The present invention relates to a terminal block for high lldl~s,l,is ,;~l~ rates in telecon~munications and data u,uuessi"g and comprisesa plastic body with at least ~ne row of chambers for insulation di ~uldc~ llL
contad elements and with sl~ts for shield plates. The slots are disposed in the 5 transverse walls between chambers and extend with axes parallel to the walls.
A terminal bloclk of the type referred to lle":i"l.. FU~I: is known in the art from U.S. Patent 5160 273. Herein it is intended to solve the problem of cross-talk through the cable wires connected to adjacent insulation .li:,ulac~",e"l contact elements by insertion of a multitude of ~I~.LIic.l:,r condudive shield plaks bet~een the individual pairs of insulation di_~ldc~lll~lll contact elements. The pro~)lem of crosstalk occurs when large volumes of illfUlllldliUI1 are lldll:,lllilll:d at high frequencies over elecdrical lines. The tldll~ aiul1 at such high frequencies causes radiation and i"ltl,rt:,~llce between adjacent cable wires particularly when those cable wires are disposed closely adjacent to each other in the terminal block. By insertion of the ~l~ulliu~l:,/ condudive shield plates a higher crosstalk attenuation at high frequencies is achieved.
The prior art terminal block comprises two parallel rows of chambers for insulation ~i~place~ contad elements. One shield plate is assigned to each. The opposite shield plates of the two rows are cc")"e. t~d by a large-area colll1e-1iul1 plate which is inserted into the respedive lower part of the terminal block. Howevel, 1 of large-area ek:ul,i~ conductive shield plates requires an increase in the construdional volume of the terminal blocks and higher costs for t~rminal block manufacture.
It is therefore the objed of the invention to provide a terminal block wherein the configurati~n of ~ Iy ahaped shield plates guarantees an effedive reduction of crosst~lk and a substantial si", ~ 1 of assembly of the shield plates and of the cable wires at the insulation ~i:,ulace,,,~,,l contact elements.
The solution of this object is achieved, according to the invention, by disposing the chambers cf a terminal unit in the plastic body at the smallestpossible distance to each otller, and by providing slots for receiving the shield plates on a lower side of the terminal block, i.e. the side from which the contact elements extend in use, in thicker transverse walls extending between respective pairs of adjacent temminal units. It is thereby possible, by means ofonly Lwo shield plates, to shield a pair of chambers which form a terminal unit and are disposed at a small distance to each other in the plastic body. The larger distance between the chambers of adjacent terminal units reduces the risk of crosstalk.
In a preferred ~",L,odi",el,l, the shield plates each have in the upper section a latch opening that cou,uer~ , with a latch lug in the plastic body when inserting the shield plate into the terminal block. The shield plates are inserted into the terminal block from the lower side of the temminal block.
Further, the shield plates have in the area of the contact pin a cutout providing favourable cable guiding. lrhe lldll~ ia~iùl1 properties are improved by a magnetic field structure favourably influenced by this measure. The shield plates are cù,~,,ecLt:d to each other by the contact pins and a circuit track, for example on a printed circuit board.
The configuration of the cable wire introduction section of the insulation displdC~ ,1 lel 1~ contact element, as provided in a preferred er"L,odi" ~t:"l according to the invention, permits an easier Le:llllilld~iull of cable wires in that the cable wires are positioned by hand and are reliably attached by a tool to the knobs in the introduction section prior to being pressed-in.
According to another ~" ,L,u~i, "e"I, the shield plates of at least one chamber can be connected by narrow webs inserted in grooves in the bottom of the plastic body. This configuration of the shield plates allows a Ic~ "y and ~col1u",:~ "y less-expensive il l ~ldlldliUI1 of the shield plates i"", " ' 'y in the upper part of the terminal block, so that the shield plates according to theinvention may also be configured for wire co"l,eulu,~ cu",,uli~il,g only one row 2t 82460 of chambers for insulation ~ JldCt:ll,el ,l contact elements and having no lowerpart.
Further three shield plates of two adjacent pairs of chambers can be co""e~ L~d to each other by narrow webs to form a shield plate cage. The three shield plates and the narrow webs cu""e~ ,y them form in the plane of the webs the shape of an 'eight' consisting of seven short sheet-metal strips.
In a particularly preferred e",l,odi",e~ one slot may be disposed in transverse walls between two pairs of closely-adjacent chambers and two slots in the transverse wall between each two pairs of closely-adjacent chambers for receiving the shield plates. A particularly compact construction of a wire connector is thereby possible.
By the pair-wise configuration of the chambers at a small spacing from each other in a row of the plastic body crosstalk attenuation of the insulation di~,ldc~",e"l contact elements inserted in those chambers is further improved. The distance of ealch pair of closely-adjacent chambers of a terminal unit to the pair of closely-adjacent chambers in an adjacent unit is larger thanthe distance between closely-adjacent chambers. Thereby the Cd~Ja~ ;~dl ,c~s of adjacent pairs of insulation dia~Jldct~ contact elements arranged in a row are further de.,t:ased and the crosstalk properties are even further improved.
The invention will next be described in greater detail by means of preferred ~",I,odi",t:l,ts utilizing the accompanying drawings in which:

According to the It~ selltdLiOI~ in Figure 1, the terminal block is formed of a plastic body 1 ~,"",,isi"~ four terminal units 26 each with two chambers 2 disposed from each other a distance 'd'. The chambers 2 are formed in the upper side 5 of the terminal block, and serve for receiving insulation di~.ld~",e"l cont3ct elements 28. Each pair of chambers 2 of a tenminal unit 26 is limited by a transverse wall 27, wherein a slot 25 is provided from the lower side 23 for the insertion of a shield plate 24 with a contact pin32. The distance d between the chambers 2 of terminal unit 26 is suL,ald"~
smaller than the distance 'D' between the chambers 2 of adjacent terminal units 26. The distance D is at least 1.5 times the distance d. Each terminal unit 26 consists of a pair of chambers 2 co"",, i~i"~ the insulation ~ia~,lace,, ,~l,l contact elements 28 and a shield plate 24. The shield plate 24 shown on the left-hand side of Figure 1 is then only ~ecessary when another terminal block is added.
The terminal block can also be formed of plastic body d5S~::Il ' '' separate foreach terminal unit 26, said asse",' " ~ being combined into an arbitrary number of terrninal units 26. The plastic bodies 1 can be lined up with the front sides37 either smoothly or by latch elements.
In Figure 2 is shown, in the side view of the terminal block, the position of the insulation displacement contact elements 28 in the plastic body 1 andl the configuration of the individual terminal units 26, as well as the distances d between the chambers 2 of a terminal unit 26 and the distances D

and, Figure 12 is a side view of the shield plate cage of Figure 10.
According to the It~ selltdLiOI~ in Figure 1, the terminal block is formed of a plastic body 1 ~,"",,isi"~ four terminal units 26 each with two chambers 2 disposed from each other a distance 'd'. The chambers 2 are formed in the upper side 5 of the terminal block, and serve for receiving insulation di~.ld~",e"l cont3ct elements 28. Each pair of chambers 2 of a tenminal unit 26 is limited by a transverse wall 27, wherein a slot 25 is provided from the lower side 23 for the insertion of a shield plate 24 with a contact pin32. The distance d between the chambers 2 of terminal unit 26 is suL,ald"~
smaller than the distance 'D' between the chambers 2 of adjacent terminal units 26. The distance D is at least 1.5 times the distance d. Each terminal unit 26 consists of a pair of chambers 2 co"",, i~i"~ the insulation ~ia~,lace,, ,~l,l contact elements 28 and a shield plate 24. The shield plate 24 shown on the left-hand side of Figure 1 is then only ~ecessary when another terminal block is added.
The terminal block can also be formed of plastic body d5S~::Il ' '' separate foreach terminal unit 26, said asse",' " ~ being combined into an arbitrary number of terrninal units 26. The plastic bodies 1 can be lined up with the front sides37 either smoothly or by latch elements.
In Figure 2 is shown, in the side view of the terminal block, the position of the insulation displacement contact elements 28 in the plastic body 1 andl the configuration of the individual terminal units 26, as well as the distances d between the chambers 2 of a terminal unit 26 and the distances D
between adjacent chambers in adjacent terminal units 26. The insulation di ,~,lacel"e"I contact eleme~1ts 28 are ;~C~-5~ from the upper side 5 of the tenminal block.
According to the It:y,~ "' " 1 of Figure 6, the insulation 5 .li~l-la~",el,L contact elements 28 have an introduction section 29 for cable wires (not shown), that section being formed by opposite knobs 30 defining a circular expanded portion 31 towards the top. Thereby, a cable wire inserted by hand into the expanded l~ortion 31 is pre-fixed and can be easily pressed into the clamping slot 6 by a suitable tool.
Figure 3 shows~ in a bottom view of the terminal block, the position of the contad pins 33 of the insulation diD,uld~ llI contact elements 28 and of the contact pins 32 of the shield plates 24 relative to each other and to thelower side 23 of the tenninal block.
From Figure 5 can be seen the confguration of the shield plates 24. The shield plates 24 ha~e a latch opening 34 coopc:ldlillg with ,t~ ,e~,~hl~, latch lugs 35 in the upper section of the plastic body 1 (Figure 4). In the areaof the contact pin 32 is provided a cutout 36 in order to guarantee optimum wireguiding.
The position of the shield plates 24 in the plastic body 1 is shown 20 in Figure 4. It becomes apparent that the rest surface of the shield plate 24 is reduced. The contact pin 32 is formed offset relative to the longitudinal axis of the shield plate 24, so that t~lere is sufficient space for the cutout 36.
In a second t:lllbo.li",~"~ according to Figures 7 to 12, each chamber 2 comprises, as is shown in Figure 7, a clamping slot 6 with lateral 25 clamping webs 7 for clamping down the insulation of a cable wire, the conductor of which is pressed into the insulation .ii~Jld.,~lllt:lll contact element 3 and is contacted in a solderless, screwless and stripless manner with the insulation ~i~lJldCt:l I ,e"I contact element 3. On the lower side 23 of the plastic body 1 are fonmed fixing pins 8 made of plastic, said pins serving for dlldl;l 111 ,e"I of the wire 30 connector, for example on printed circuit boards.
As is shown il1 Figures 7 an~ 9, the distance d between two i, "~, ' ' 'y ~djacent clamping slots 6 serving for the insertion of a pair of insulation .li~Jldce",t:"~ contact elements 3 is d,u,~ iidLly smaller than the distance D between the clamping slot 6 of the one pair of chambers 2 and the clamping slot 6 of the adjacent pair o~ chambers 2. In the transverse wall 9 formed between two pairs of closely-adjacent chambers 2 a slot 11 extends from the lower side 23. In the wider transverse wall 10 disposed between two groups of closely-adjacent pairs of chambers 2 two slots 11 extend from the lower side 23. The two slots 11 are connected on the lower side 23, in the bottorn 12 of the wire conn~ctor, by grooves 13, 14, 15, as is shown in the botto~ view of Figure 9.
Into the slots 11 and grooves 13 to 15 of two adjacent pairs of chambers 2 or two adjacent groups of chambers 2, respectively, is inserted a shield plate cage 15A, as s~lown in Figures 10 to 12. Said cage cu"".ri~es three shield plates 16 inserte~ from the lower side 23 into the slots 11 betweenthe pairs of adjacent chambers 2 in the plastic body 1, and further comprises narrow webs 17, 18, 19 sn~p-fitted into the bottom grooves 13 to 15 of the plastic body 1 when the shield plates 16 are fu~ly slid into the respective slots 1 1 .
The three shi~ld plates 16 and the narrow webs 17 to 19 co"lle~;Li"g them have in the plane of the webs 17 to 19 the shape of an eight formed of seven short sheet-metal strips, as is shown in Figure 10. The pair of outside shield plates 16 in the didgol1~:ly opposite corners 20 each have a slight bend, as is shown in Figure I0.
In order that the two shield plate cages 1 5A of the plastic body 1 of a wire connector shown in Figures 7 to 9 fit, a slot 11 is fommed in the transverse wall 9 between th~ two pairs of closely-adjacent chambers 2. Two parallel slots 11 are each fornled in the transverse wall 10 between two groups of pairs of chambers 2 disposed closely side-by-side for receiving the shield plates 16 of the respective s~lield plate cage 15A.
Each of the two shield plate cages 15A has in the central area of the plastic body 1 of the wire connector wherein two parallel slots 11 for two shield plates 16 are provided in the transverse wall 10 one earthing tapping portion 21 on the lower side of the shield plates 16 as is shown in Figures 7 5 11 and 12 These are co,~"eut~d to a not-shown earthing position of a not-shown printed circuit board. The individual insulation di:l~.ldct:l"el,l contactelements 3 have contact pins 22 projecting from the lower side for ~ u,~l-e~ ~i to the respective circuit tracks of the printed circuit board.
According to the It:y,~ "' " 1 of Figure 6, the insulation 5 .li~l-la~",el,L contact elements 28 have an introduction section 29 for cable wires (not shown), that section being formed by opposite knobs 30 defining a circular expanded portion 31 towards the top. Thereby, a cable wire inserted by hand into the expanded l~ortion 31 is pre-fixed and can be easily pressed into the clamping slot 6 by a suitable tool.
Figure 3 shows~ in a bottom view of the terminal block, the position of the contad pins 33 of the insulation diD,uld~ llI contact elements 28 and of the contact pins 32 of the shield plates 24 relative to each other and to thelower side 23 of the tenninal block.
From Figure 5 can be seen the confguration of the shield plates 24. The shield plates 24 ha~e a latch opening 34 coopc:ldlillg with ,t~ ,e~,~hl~, latch lugs 35 in the upper section of the plastic body 1 (Figure 4). In the areaof the contact pin 32 is provided a cutout 36 in order to guarantee optimum wireguiding.
The position of the shield plates 24 in the plastic body 1 is shown 20 in Figure 4. It becomes apparent that the rest surface of the shield plate 24 is reduced. The contact pin 32 is formed offset relative to the longitudinal axis of the shield plate 24, so that t~lere is sufficient space for the cutout 36.
In a second t:lllbo.li",~"~ according to Figures 7 to 12, each chamber 2 comprises, as is shown in Figure 7, a clamping slot 6 with lateral 25 clamping webs 7 for clamping down the insulation of a cable wire, the conductor of which is pressed into the insulation .ii~Jld.,~lllt:lll contact element 3 and is contacted in a solderless, screwless and stripless manner with the insulation ~i~lJldCt:l I ,e"I contact element 3. On the lower side 23 of the plastic body 1 are fonmed fixing pins 8 made of plastic, said pins serving for dlldl;l 111 ,e"I of the wire 30 connector, for example on printed circuit boards.
As is shown il1 Figures 7 an~ 9, the distance d between two i, "~, ' ' 'y ~djacent clamping slots 6 serving for the insertion of a pair of insulation .li~Jldce",t:"~ contact elements 3 is d,u,~ iidLly smaller than the distance D between the clamping slot 6 of the one pair of chambers 2 and the clamping slot 6 of the adjacent pair o~ chambers 2. In the transverse wall 9 formed between two pairs of closely-adjacent chambers 2 a slot 11 extends from the lower side 23. In the wider transverse wall 10 disposed between two groups of closely-adjacent pairs of chambers 2 two slots 11 extend from the lower side 23. The two slots 11 are connected on the lower side 23, in the bottorn 12 of the wire conn~ctor, by grooves 13, 14, 15, as is shown in the botto~ view of Figure 9.
Into the slots 11 and grooves 13 to 15 of two adjacent pairs of chambers 2 or two adjacent groups of chambers 2, respectively, is inserted a shield plate cage 15A, as s~lown in Figures 10 to 12.
