Description

TEST CONNECTION APPARATUS FOR A DATA JACK
RELATED APPLICATIONS
S
This application claims the benefit of priority of German Utility Model Serial No. 202011003115.2 filed on February 23, 2011 the content of which is relied upon and incorporated herein by reference in its entirety.
The invention relates to a test connection apparatus for a data jack according to the preamble of Claim 1.
US 2006/0014410 Al discloses a data jack which has a housing and a connecting device which is positioned in the housing. The housing is formed by two sections, specifically by a front housing section, into which a data plug can be inserted so as to make contact with the connecting device, and by a rear housing section by means of which a data cable can be routed to the connecting device which is positioned in the housing.
The connecting device has contact springs, which form input connections of the connecting device, and has insulation-displacement terminal contacts, which are preferably in the form of insulation-displacement connection (IDC) contacts, which form output connections of the connecting device. If a data plug is inserted into the data jack by way of its plug-type contacts, the plug-type contacts of the data plug make contact with the contact springs of the connecting device and therefore the input connections of the said connecting device, The insulation-displacement terminal contacts of the connecting device, and therefore the output connections of the said connecting device, can make contact with data conductors of the data cable.
A data jack is designed for a defined data transmission rate of, for example, 10 Gait/s with a defined fundamental frequency component of, for example, 500 MHz and, in this context, has to meet specific, technical requirements, for example, in respect of so-called near-end crosstalk, so-called far-end crosstalk and so-called return loss. The data jacks have to be S subjected to tests or checks in order to check whether data jacks meet the specific, technical requirements.
If a data jack according to the prior art is to be
subjected to a test or a check, the output connections of a data jack have to be connected, with a high level of complexity, to cables of a defined length and, by means of the cables, to electrical resistors for as long as it takes to carry out the tests. To date, this has been done manually, and therefore it is difficult to provide reproducible results of such tests. There is therefore a need for a test connection apparatus for a data jack which allows the output connections of the data jack for carrying out a test to be terminated in a simple and reliable manner while ensuring reproducible results.
The present invention is based on the problem of providing a novel test connection apparatus for a data jack. This problem is solved by a test connection apparatus for a data jack according to Claim 1. The test connection apparatus according to the invention comprises a plurality of printed circuit boards which are arranged in a three-dimensional manner in relation to one another, specifically at least one first printed circuit board which has plug-type contacts for making electrical contact with the output connections of a data jack, and at least one second printed circuit board which forms an angle with the or each first printed circuit board and is fitted with electrical resistors for electrically terminating the plug-type contacts, with the electrical resistors of the or each second printed circuit board being electrically conductively connected to the plug-type contacts of the or each first printed circuit board by means of conductor tracks.
In order to prepare for a test or a check using the test connection apparatus according to the invention, the output connections of a data jack to be checked or to be tested only have to be inserted into the plug-type contacts of a first printed circuit board of the test connection apparatus according to the invention.
The assemblies which are required to carry out a defined check are integrated in the printed circuit boards of the test connection apparatus according to the invention, and therefore a check can be carried out after simply connecting the data jack and the test connection apparatus according to the invention.
As a result, it is not only easier to carry out checks but reproducible results of such checks can also be provided.
The test connection apparatus preferably comprises two opposing first printed circuit boards, with each first printed circuit board having two rows of in each case a plurality of plug-type contacts for making electrical contact with the output connections of a data jack, which rows run approximately parallel to one another, with two second printed circuit boards, which are fitted with the electrical resistors which are connected to the plug-type contacts of the first printed circuit boards by means of the conductor tracks, interacting with each first printed circuit board, and with the first printed circuit boards and the second printed circuit boards, which are arranged perpendicular to the respective first printed circuit board, in each case forming side faces of a parallelepiped, in particular of a cuboid.
The arrangement of the printed circuit boards of the test connection apparatus according to the invention in the form of a cuboid is preferred.
S According to an advantageous development of the invention, in each case two plug-type contacts of one of the first printed circuit boards are connected to one another by means of at least one electrical resistor for the purpose of ensuring differential-mode termination of the plug-type contacts, with in each case two plug-type contacts of an opposing, other first printed circuit board being connected to one another by means of at least three electrical resistors for the purpose of ensuring common-mode termination of the plug-type contacts and being contact-connected to earth potential.
When the plug-type contacts of a first printed circuit board exhibit differential-mode termination and the plug-type contacts of another first printed circuit board exhibit common-mode termination, the test connection apparatus according to the invention can be used to carry out various checks.
Preferred developments of the invention can be found in the dependent claims and the description which follows.
Exemplary embodiments of the invention, without being restricted thereto, will be explained in greater detail with reference to the drawing, in which: Fig. 1 shows a schematic, perspective view of a test connection apparatus according to the invention for a data jack according to a first exemplary embodiment of the invention with a differential-mode termination of plug-type contacts; Fig. 2 shows a schematic developed view of the test connection apparatus of Fig. 1; Fig. 3 shows a schematic, perspective view of a test connection apparatus according to the invention for a data jack according to a second exemplary embodiment of the invention with a common-mode termination of plug-type contacts; Fig. 4 shows a schematic developed view of the test connection apparatus of Fig. 3; Fig. 5 shows a further development of the test connection apparatus of Figs 1, 2; Fig. 6 shows a further development of the test connection apparatus of Figs 3, 4; Fig. 7 shows a schematic, perspective view of a test connection apparatus according to the invention for a data jack according to a third exemplary embodiment of the invention with a differential-mode termination of plug-type contacts and with a common-mode termination of plug-type contacts; Fig. 8 shows a schematic, perspective view of a test connection apparatus according to the invention for a data jack according to a fourth exemplary embodiment of the invention with a differential-mode termination of plug-type contacts and with a common-mode termination of plug-type contacts; and Fig. 9 shows a test connection apparatus together with an adapter.
The present invention relates to a test connection apparatus for a data jack, for example for a RJ-45 data jack or a GG-45 data jack or an AJ-45 data jack.
The test connection apparatus according to the invention allows reproducible tests and checks to be carried out on a data jack without complex, manual preparation of the data jack. In order to prepare for a test or a check, the data jack only has to be connected to the test connection apparatus. The basic structure of a data jack which is to be tested is familiar to a relevant person skilled in the art and known, for example, from US 2006/0014410 Al.
Therefore, a data jack comprises a connecting device with input connections and output connections, it being possible for a data plug to make contact with the input connections of the data jack, and with it being possible for data conductors of a data cable to make contact with the output connections of the data jack in the case of operation and for the test connection apparatus according to the invention to make contact with the output connections of the data jack in the case of testing. The output connections of a data jack, it being possible for the test connection apparatus according to the invention to make contact with the said output connections for the purpose of a check, are, in particular, insulation-displacement terminal contacts which are in the form of insulation-displacement connection (mc) contacts. The connecting device of the data jack is positioned in a housing of the said data jack.
A test connection apparatus according to the invention has a plurality of printed circuit boards which are arranged in a three-dimensional manner in relation to one another, specifically at least one first printed circuit board which has plug-type contacts for making electrical contact with the output connections of a data jack which is to be tested, and at least one second printed circuit board which forms an angle with the or each first printed circuit board and is fitted with electrical resistors for electrically terminating the plug-type contacts and therefore output connections, which are inserted into the plug-type contacts, of a data jack which is to be tested.
The electrical resistors of the or each second printed circuit board are electrically connected to the plug-type contacts of the or each first printed circuit board by means of conductor tracks, with these conductor tracks being designed in a three-dimensional manner so as to correspond to the three-dimensional arrangement of the printed circuit boards.
Figs 1 and 2 show a first exemplary embodiment of a test connection apparatus 10 according to the invention f or a data jack, with the test connection apparatus 10 of Figs 1 and 2 comprising a first printed circuit board 11 and two second printed circuit boards 12 and 13 which are arranged in a three-dimensional manner in relation to one another and, according to Figs 1 and 2, form side walls of a cuboid, in particular of a cube.
The first printed circuit board 11 comprises plug-type contacts 14 for making electrical contact with the output connections of a data jack, it being possible to insert the output connections of a data jack which is to be tested into the plug-type contacts 14 of the first printed circuit board 11 and thus to make electrical contact with the said plug-type contacts. In this case, the arrangement of the plug-type contacts 14 on the first printed circuit board 11 corresponds to the arrangenient of the output connections of the data jack which is to be tested, with, according to Figs I and 2, the plug-type contacts 14 being arranged on the first printed circuit board 11 in the form of two rows 15, 16 which run parallel to one another. In this case, a first row 15 of plug-type contacts 14 extends parallel to a first side 17 of the first printed circuit board 11, whereas a second row 16 of plug-type contacts 14 extends parallel to a second side 18 of the first printed circuit board 11.
A second printed circuit board 12 and 13 is in each case positioned adjacent to these two sides 17 and 18 of the first printed circuit board 11, the rows 15 and 16 of plug-type contacts 14 extending along the said sides, with each of these two second printed circuit boards 12 and 13 being fitted with electrical resistors 19 for electrically terminating the plug-type contacts 14 and therefore the output connections, which can be inserted into the plug-type contacts 14, of a data jack which is to be tested.
According to Figs 1 and 2, the second printed circuit board 12, which is arranged adjacent to the side 18 of the first printed circuit board 11, is fitted with the electrical resistors 19 for electrical differential-mode termination of the plug-type contacts 14 of the row 16 of plug-type contacts 14. The second printed circuit board 13, which is positioned on the opposite side 17 of the first printed circuit board 11, is fitted, in contrast, with the electrical resistors 19 for electrical differential-mode termination of the plug-type contacts 14 of the row 17 or of the output connections, which are inserted into said plug-type contacts, of a data jack which is to be tested.
As already cited, the printed circuit boards 11, 12 and 13 form side faces of a cuboid or cube, as a result of which the second printed circuit boards 12 and 13, which are positioned on opposing sides 17 and 18 of the first printed circuit board 11, are in each case positioned perpendicular to the first printed circuit board 11, that is to say form an angle of approximately 900 with the said first printed circuit board.
As can be seen in Figs 1 and 2, in each case two plug-type contacts 14 of a row 15 or 16 jointly exhibit common-mode termination by means of a corresponding resistor 19, with the plug-type contacts 14 being electrically conductively connected to the respective resistor 19 by means of conductor tracks 20 with three- dimensional contours. In this case, the three-dimensional contouring of the electrical conductor tracks 20 is matched to the three-dimensional positioning of the printed circuit boards 11, 12 and 13.
In the exemplary embodiment of Figs 1 and 2, in each case two plug-type contacts 14 of a row 15 or 16 are connected to one another and exhibit differential-mode termination by means of the respective electrical resistor 19. Such differential-mode termination serves to carry out a defined check on a data jack which is to be tested.
Figs 3 and 4 show an exemplary embodiment of a test connection apparatus 10' which, in terms of its basic structure, corresponds to the test connection apparatus 10 of Figs 1 and 2 and which differs from the test connection apparatus 10 of Figs 1 and 2 only in respect of the specific electrical termination of the contacts 14 of the first printed circuit board Ii, and therefore, in order to avoid unnecessary repetition, only those details by virtue of which the exemplary embodiment of Figs 3 and 4 differs from the exemplary embodiment of Figs 1 and 2 will be discussed below.
Reference is made to the above information in respect of all other details, and therefore identical reference numerals are also used for identical assemblies.
Whereas in each case two plug-type contacts 14 of a row 15, 16 are connected to one another and subjected to electrical differential-mode termination by means of a common electrical resistor 19 in the exemplary embodiment of Figs 1 and 2, in each case two contacts 14 of a row 15, 16 exhibit electrical common-mode termination in the exemplary embodiment of Figs 3 and 4. The term common-mode termination can also be used in German. For the purpose of common-node termination, each plug-type contact 14 has an associated individual electrical resistor l9a and, secondly, in each case two plug-type contacts 14 of a row 15, 16 have an associated common electrical resistor 19b, with the two plug-type contacts 14 being connected to one another -10 -and being connected to earth potential 21 by means of these resistors 19a and l9b. The data jack can be subjected to a further defined check on account of such common-mode termination of the plug-type contacts 14 and therefore of the output connections, which are inserted into the plug-type contacts 14, of a data jack which is to be tested.
Fig. S shows an exemplary embodiment based on the test connection apparatus 10 of Figs 1 and 2 in which slots 25, specifically two slots 25 which run approximately perpendicular to one another, are made in the first printed circuit board 13. which has the plug-type contacts 14 for making electrical contact with the output connections of a data jack.
In the shown exemplary embodiment, the slots 25 separate or divide or subdivide the first printed circuit board 11 into four partial segments 26 which are connected or coupled to the edges, with two of the plug-type contacts 14, specifically those plug-type contacts 14 which are coupled by means of the resistors 19 to form a pair of plug-type contacts, are associated with each partial segment 26.
Fig. 6 shows an exemplary embodiment based on the test connection apparatus 10 of Figs 3 and 4 in which such slots 25 are likewise made in the first printed circuit board 11 which has the plug-type contacts 14 for making electrical contact with the output connections of a data jack.
The crosstalk in each case between the pairs of plug-type contacts or combinations of pairs of the plug-type contacts 14 which are coupled by means of the resistors 19 and 19a, 19b can be reduced and therefore improved by virtue of the slots 25 and by virtue of metal and preferably plate-like or web-like shield elements &zot shown) which are inserted into the slots 25.
-11 -This reduction in the crosstalk between the pairs of plug-type contacts can also be implemented by earth shield conductor tracks, which are composed of copper S for example, being mounted on the respective first printed circuit board 11 as an alternative to the slots but in the same position as the said slots. These conductor tracks then, in turn, subdivide the respective first printed circuit board 11 into four partial segments 26, with two of the plug-type contacts 14, specifically those plug-type contacts 14 which are coupled to form a pair of plug-type contacts, being associated with each partial segment 26.
In the exemplary embodiments of Figs 1 to 4, the respective test connection apparatus 10 or 10' is in each case suitable for carrying out a defined check, specifically either for carrying out a check with differential-mode termination of the plug-type contacts 14 or of the output connections, which are inserted into the plug-type contacts 14, of the data jack or for carrying out a check with common-mode termination of the plug-type contacts 14 or of the output connections, which are inserted into the said plug-type contacts, of a data jack.
In this case, it is sufficient for the three printed circuit boards 11, 12 and 13, which form three side faces or side walls of a cuboid or cube, to be designed in. the form of printed circuit boards.
The other side faces or side walls of the cuboid or cube, which are not provided with reference numerals in Figs 1 to 4, can also be designed in the form of printed circuit boards, but do not have to be designed in the form of printed circuit boards in the exemplary embodiments of Figs 1 to 4 since they serve merely to mechanically stabilize the printed circuit boards 11, -12 - 12 and 13 which are arranged in a three-dimensional manner in relation to one another.
It should be noted at this point that the three printed circuit boards 11, 12 and 13 can also be arranged such that they form a triangle in cross section, so that the said printed circuit boards then form side walls, in particular, of a tetrahedron or of another polyhedron.
Figs 7 and 8 schematically show further exemplary embodiments of test connection apparatuses 10'' and 10''' which have two opposing first printed circuit boards ha and llb which form opposite side walls of the shown cuboid or cube.
Each of these first printed circuit boards lla, llb is fitted with plug-type contacts 14 which are positioned on the respective first printed circuit board lla, llb in the form of two rows 15, 16 which run parallel to one another, with in each case a second printed circuit board 12a, 13a or l2b, l3b adjoining each first printed circuit board ha or llb adjacent to each row of plug-type contacts 14, the said second printed circuit board being fitted with electrical resistors (not shown in Fig. 7) for electrically terminating the plug-type contacts 14, specifically firstly for differential-mode termination of plug-type contacts and secondly for common-mode termination of plug-type contacts.
In this case, the plug-type contacts 14 of a first printed circuit board ha preferably exhibit differential-mode termination, whereas the plug-type contacts 14 of the other first printed circuit board lib are preferably subjected to common-mode termination, so that one and the same test connection apparatus 10'', 10''' can then subject the data jack to a different check, irrespective of which plug-type contacts 14 of which first printed circuit board ha or llb the output connections of a data jack are inserted -13 -into, specifically with electrical differential-mode termination or with electrical common-mode termination of the output connections, which are inserted into the respective plug-type contacts 14, of the data jack.
Fig. 7 also shows that, in the exemplary embodiment according to Fig. 7, the plug-type contacts 14 which are arranged on the opposing first printed circuit boards ha and hlb, in each case in the form of a row and in parallel, are arranged in such a way that the rows 15 and 16 of plug-type contacts 14, which rows run on the opposing first printed circuit boards ha and 1db, have a different orientation, that is to say run such that they are offset through 900 in relation to one another. In this case, all six side faces of the cuboid shown in Fig. 7 are then formed by printed circuit boards, specifically by two opposing printed circuit boards ha and llb and by four second printed circuit boards 12a, 12b, 13a, 13b which run perpendicular to these first printed circuit boards ha, llb. The electrical resistors (not shown) for electrical differential-mode termination or electrical common-mode termination of the plug-type contacts 14 which are positioned on different first printed circuit boards ha, 1db are then positioned on in each case individual second printed circuit boards 12a, 13a and 12b, 13b.
In contrast, Fig. 8 shows a variant of a test connection apparatus 10''' in which the plug-type contacts 14, which are positioned on the opposing first printed circuit boards ha, lib, for the output connections of a data jack which is to be tested run with the same orientation in which the rows of plug-type contacts 14 of the opposing printed circuit boards ha, llb are oriented parallel to one another.
Common second printed circuit boards 12, 13 are then provided for the opposing first printed circuit boards -14 -ha, hib, the said common second printed circuit boards then being fitted, preferably on different sides of said common second printed circuit boards, with the electrical resistors for electrical differential-mode termination or electrical common-mode termination of the plug-type contacts 14 of the opposing first printed circuit boards ha, llb.
In this case, four side walls of a cuboid are then formed by printed circuit boards 1, llb, 12 and 13 and the two remaining side walls of the cuboid serve to mechanically stabilize the printed circuit boards and therefore do not have to be designed in the form of electrical printed circuit boards.
The slots 25 with the shield elements or the earth shield conductor tracks for reducing the crosstalk between combinations of pairs of plug-type contacts 14 can be used in the region of the first printed circuit boards ha, lib in the exemplary embodiments of Figs 7 and B too.
As already cited, the plug-type contacts 14 are arranged on the or each first printed circuit board 11, ha, llb in such a way that the arrangement of the said plug-type contacts corresponds to the positioning of the output connections of a data jack which is to be tested.
Since different data jacks from different manufacturers can differ in terms of the geometric positioning of the output connections, provision is made, according to an advantageous development of the invention, for a test connection apparatus 10, 10', 10'' or 10''' (see Fig. 9) to be matched to different data jacks, in particular to a different configuration of the output connections of a data jack, by means of an adapter 22. Therefore, a test connection apparatus 10, 10', 10'' and 10''' can be matched firstly mechanically to data jacks with -15 -different geometric external contours and secondly electrically to data jacks with a different configuration of the output connections by means of an adapter 22.
S
The adapter 22 has corresponding plug-type contacts for accommodating the output connections of a data jack which is to be tested, with one of the first printed circuit boards 11, ha, llb, for example the plug-type contacts 14 of the said printed circuit boards, or the respective second printed circuit boards 12, 13, 12a, 12b, 13a, 13b of the respective test connection apparatus 10, 10', 10'' or 10''' making electrical contact with these plug-type contacts of the adapter 22 in order to electrically terminate output connections, which are accommodated in the plug-type contacts of the adapter 22, of a data jack for a check which is to be carried out.
Fig. 9 schematically shows how the adapter 22 can be attached to a first printed circuit board 11, ha or hib of a test connection apparatus 10, 10', 10'' or 10''' by means of attachment means 23.
