Definitions

  • the invention relates to a connector assembly according to the preamble of claim 1.
  • Such connector assemblies are known in various embodiments.
  • attention has mainly been paid to the mechanical aspects of the connector assembly, in particular with respect to the forces required for mating and unmating the connector elements.
  • Attention was only paid to the electrical aspects in that one aimed at realizing good reliable connections between the contacts of both connector elements.
  • the electrical performance of the contacts as a circuit element becomes important.
  • problems occur with higher signal speeds with respect to cross-talk between signal contacts, transmission losses, reflections and ground bounce or switching noise. Despite an optimal distribution of the ground and signal contacts these problems cannot be eliminated below rise times of 0,6ns in the known connector assemblies.
  • a connector assembly according to the preamble of claim 1 is known from US-A-4 867 707.
  • the contact means of each outer conductor adapted to contact the adjacent ground contacts is made as a female contact type for receiving and enclosing a ground contact pin.
  • the invention aims to provide a connector assembly of the above-mentioned type wherein the problems occurring at high signal speeds in the known connector assemblies can be obviated by making the connector elements in such a mannerthat the performance of the contacts as a circuit element can be previously determined and said signal distortions are minimized.
  • the connector assembly according to the invention is characterized by the features of the characterizing part of claim 1.
  • the connector assembly according to the invention shows the advantage that the connector elements and the male and female contacts can be made in a usual manner so that all known design and manufacturing techniques of the ususal connector assemblies can be used advantageously.
  • the connection between the male and female contacts is comparable with the same of the known connector assemblies so that the favourable mechanical properties thereof, such as mating/unmating forces and in particular the tolerances with respect to the mutual positions of the contacts are maintained when used in rack and panel configurations.
  • all contacts and outer conductors can be manufactured from metal strips by stamping and forming so that the manufacturing costs of the connector assembly according to the invention are low.
  • Each signal contact of the second connector element is mounted in the corresponding outer conductor by means of a dielectric insert.
  • the impedance of each signal contact can be determined by using an insert wherein by providing more or less recesses the dielectric constant of the insert between the signal contact and the outer conductor can be determined. Thereby the combination of signal contact and outer conductor which can be considered as a transmission line, can be provided with a desired impedance.
  • a connector assembly 1 comprising a first connector element 2 with a first housing 3 of insulating material and contact pins 4 and 5 arranged in parallel rows rand columns c (see fig. 3).
  • These contact pins 4, 5 each have a connection element 6, by which the contact pins 4, 5 can be connected with the plated inner wall of holes in a printed circuit board 7 indicated by a dashed.
  • the connection elements 6 are preferably provided with a known press-fit portion not further shown.
  • the connector element 2 comprises two rows with signal contact pins 4 which are indicated by an s, wherein at both sides of each row with only signal contact pins 4 a row with only ground contact pins 5 indicated by a g is provided.
  • the arrangement is such that a column with only ground contact pins 5 is provided on both sides of each column c with alternatingly signal contact pins 4 and ground contact pins 5.
  • the rows with contact pins 4, 5 have a fixed intermediate spacing of 2mm, while in row direction the ground contact pins 5 lie at a fixed intermediate spacing of 2mm and the signal contact pins 4 lie at a fixed intermediate spacing of 4mm.
  • the connector assembly 1 is further provided with a second connector element 8 with a second housing 9 of insulating material adapted to be inserted with a mating side 10 in the first housing 3 of the connector element 2.
  • the second connector element 8 is shown in perspective in fig. 5 and includes two rows with female signal contacts 11 for contactinq the signal contact pins 4 when the second housing 9 is received in the first housing 3.
  • Each signal contact 11 is enclosed by an outer conductor 12 which seen in column direction has opposite contact springs 13. In mated position these contact springs 13 contact the ground contact pins 5 of the first connector element 2 lying in the same column as the corresponding signal contact pin 4.
  • the outer conductors 12 Seen in row direction the outer conductors 12 have opposite contact tongues 14 adapted to contact ground contact plates 15 located on both sides of each outer conductor 12 in the second housing 9.
  • the contact tongues 14 lying at the mating side in fig. 5 conduct the current to the inner side of the outer conductor 12 whereas the contact tongues 14 lying at the other end conduct the current from the inner side of the outer conductor to the ground contact plates 15.
  • Fig. 4a shows one ground contact plate 15 in perspective.
  • This ground contact plate 15 is provided with female contact elements 16 at the mating side, which contact elements 16 cooperate with the columns with only ground contact pins 5 of the first connector element 2. In this manner a very good ground connection between both connector elements 2, 8 is obtained, wherein a favourable current distribution in the outer conductors 12 occurs.
  • connection elements 17 and 18 are provided with a press-fit portion.
  • ground contact plates 15 can be closed by providing a ground contact plate 15 with extensions which extend from this ground contact plate 15 to the adjacent ground contact plate 15. Thereby the signal contacts 11 will be fully enclosed by ground contact plates.
  • the signal contacts 11 Due to the fact that the signal contacts 11 are surrounded by the outer conductors 12 and are further enclosed between the ground contact plates 15, the signal contacts 11 with the outer conductor 12/ground contact plates 15 form a transmission line with a geometry, of which the electrical parameters and thereby the performance as circuit element can be determined.
  • the signal contacts 11 are mounted in the outer conductors 12 by means of dielectric inserts 19. These dielectric inserts 19 which can be manufactured by injection molding at low costs, have a predetermined dielectric constant. By providing larger or smaller recesses so that more or less air is present between the signal contacts 11 and the outer conductors 12, this dielectric constant can be determined and thereby among others the impedance of the transmission line formed by the signal contacts 11 and the outer conductors 12/ground contact plates 15. In this manner a connection can be realized with a constant impedance, wherein cross-talk between signal contacts cannot occur because each signal conductor is surrounded by a ground conductor.
  • connection elements 17, 18 of the signal contacts 11 and the ground contact plates 15 may also be made as contact springs adapted for surface mounting as appears from fig. 2, showing a connector assembly, the connector element 2 of which fully corresponds with the connector element 2 of fig. 1 and the connector element 8 of which is provided with ground contact plates 20 and signal contacts 11 adapted for surface mounting.

  • two rows of ground contact pins 5 are mounted between the two rows of signal con) tact pins 4.
  • Ground contact plates 23 each having a contact spring 18' are used, which contact plates 23 can only contact the ground contact pins 5 on both sides of the corresponding signal contact pins 4. Thereby separated ground connections for the two rows of signal contact pins 4 are obtained. Due to the increased width of the connector assembly 21 it is also possible to use a printed circuit board 22 with increased thickness.
  • Fig. 7 shows in perspective one outer conductor 24 which can be mounted in the second connector element 8 for connecting coaxial cables 25 to the printed circuit board 7.
  • the outer conductor 24 comprises a connection element 26 to provide a simple connection with the outer conductor 27 of the coaxial cable 25. To this end the connection element 26 is first bent around the outer conductor 27.
  • the signal contact not further shown and mounted in the outer conductor 24 by the dielectric insert 19, has a connection element 28 for connecting the inner conductor 29 of the coaxial cable 25.
  • the connection between the outer conductor 27 and the inner conductor 29 can be obtained by soldering.
  • Fig. 8 shows a perspective view of an amended embodiment of the second connector element 8 with the housing 9, wherein the outer conductors 12 at the side opposite of the mating side 10 are provided with an extension 31 having two ground contact pins 32 to be connected to a printed circuit board 33.

  • each group of one or more signal contacts a ground connection which is independent of the same of other groups of signal contacts.
  • a programmable lay-out of ground connections is possible.
  • fig. 9 schematically shows a section of the housing 9 of the connector element 8, wherein for the sake of clearness the outer conductors 12 and the inserts 19 are not shown.
  • the signal contacts 11 are indicated by an open rectangle, whereas the locations for the contact pins 4, 5 are indicated by shaded squares.
  • ground contact plates 36 are used which are separated for the two rows of signal contact pins 4 and which are indicated in fig. 9 by an oblique shading.
  • ground contact plates 36 have only one female contact element 16 which can only contact a corresponding ground contact pin 5 of the outermost rows of ground contact pins 5.
  • insulating plates 37 are provided at three locations in the housing 9 of the second connector element 8, while in the middle row of ground contact pins 5 only one ground contact pin 5 is mounted and four non-conductive insulating pins 38 (also horizontally shaded).
  • the outer conductors 12 of different groups of signal contact pins 4 and corresponding female signal contacts 11 are insulated with respect to each other, so that the ground connection of these groups is separated and these groups cannot effect each other.
  • each desired group of signal contacts with common ground connection can be realized. It is noted that instead of insulating pins 38 it is sufficient just to omit the ground contact pins 5 for separating the outer conductors 12 lying in one column.
  • the ground contact plates 36 can also be coated on one side with an insulating layer to obtain a separation between adjacent outer conductors 12. Thereby not only a separation is possible but the outer conductor 12 lying at the conductive side of the ground contact plate 36 maintains its ground connection through this ground contact plate.
