Description

Circuit board connector assembly

The invention relates to a connector assembly for printed circuit boards, comprising a first connector element with a first housing of insulating material and regularly arranged male signal and ground contacts, which can be connected to a printed circuit board, and a second connector element with a second housing of insulating material which can be inserted into the first housing with an insertion side, and with regularly arranged female signal and ground contacts with a connecting element, which female contacts make contact with corresponding male contacts when the second housing is accommodated in the first housing.

Such connector assemblies are known in various embodiments. In the known connector assemblies, the design has mainly focused on the mechanical aspects of the connector assembly, in particular with regard to the forces required for coupling and uncoupling the connector elements.

Attention was paid to the electrical aspects only to the extent that efforts were made to achieve good reliable connections between the contacts of the two contact elements. However, with increasing speed of the digital signals to be transmitted, i.e. decreasing rise times, the electrical behavior of the contacts as a circuit element becomes important. With the known connector assemblies, problems arise at higher speeds with regard to the crosstalk between signal contacts, transmission loss, reflections and ground noise or switching noise. In the known connector assemblies, in spite of an optimum distribution of the ground and signal contacts, these problems cannot be obviated from a rise time of less than 0.6 ns.

The object of the invention is to provide a connector assembly of the type mentioned in the preamble, in which the problems that arise at high signal speeds with the known connector assemblies can be overcome by designing the connector elements in such a way that the behavior of the contacts as a circuit element can be predetermined and said signal distortions are minimized.

To this end, the connector assembly according to the invention is characterized in that the second connector element is provided with a number of outer conductors, each of which substantially encloses at least one signal contact in the circumferential direction and which each make contact with the neighboring ground contacts of the / each associated signal contact of the first connector element .

In this way it is achieved that the signal contacts in the coupled state of the connector elements together with the associated outer conductors each form more or less a transmission with a geometry, the dimensional parameters of which can be determined in such a way that the electrical requirements are met, attached to the connector assembly. In addition, this allows to create in advance an equivalent electrical schematic of the connector that can be used in the design of the overall system, so as to take into account the electrical behavior of the connector assembly from the outset. The latter is an important advantage, since at high bitrates an interaction occurs between the connector and the surrounding connection elements of the system, thereby influencing the operation of the entire system. In the connector assembly according to the invention, it is now possible to achieve optimum operation despite this interaction.

Furthermore, the connector assembly according to the invention has the advantage that the connector elements and the male and female contacts can be designed in a usual manner, so that advantageous use can be made of all known design and manufacturing techniques of the conventional connector assemblies. The connection between the male and female contacts is comparable to that of the existing connector assemblies, so that its favorable mechanical properties, such as coupling forces / decoupling forces and in particular the tolerances with regard to the mutual positions of the contacts, are retained when used in " rack and panel "configurations. Furthermore, all contacts and outer conductors can be made from metal strips by stamping and deforming, so that the manufacturing costs of the connector assembly according to the invention are low.

Preferably, each signal contact of the second connector element is mounted in the associated outer conductor by means of a dielectric insert. In this way, a reliable mounting of the signal contact in the associated outer conductor is achieved. The impedance of each signal contact can be determined by using an insert, whereby the dielectric constant of the insert between signal contact and outer conductor can be determined by making more or less recesses. As a result, the combination of signal contact and outer conductor to be regarded as a transmission line can be given a desired impedance.

Fig. 18 is a perspective view of the outer conductors with signal contacts of the connector element of FIG. 17.

Fig. 1 shows a cross section of a connector assembly 1, which is provided with a first connector element 2 with a first housing 3 of insulating material and contact pins 4 and 5 arranged in parallel rows r and columns c (see fig. 3). contact pins 4, 5 each have a connecting element 6, with which the contact pins 4, 5 can be connected to the inner wall of holes lined in a conductive material in a printed circuit board 7. For this purpose, the connecting elements 6 are preferably constructed with an unspecified , known per se "press-fit" part.

As shown in Figs. 1 and 3, the connector element 2 is provided with two rows of signal contact pins 4, which are indicated by an s, with on each side of each row with only signal contact pins 4 a row with only earth contact pins 5, which ag are indicated. There is a column with only ground contact pins 5 on either side of each column c with alternating signal contact pins 4 and ground contact pins 5. The rows of contact pins 4, 5 are at a fixed intermediate distance of 2 mm, while in the direction of travel the ground contact pins 5 are located at a fixed intermediate distance of 2 mm and the signal contact pins 4 at a fixed intermediate distance of 4 mm.

The connector assembly 1 is further provided with a second connector element 8 with a second housing 9 of insulating material, which can be plugged into the first housing 3 of the connector element 2 with an insertion side 10. The second connector element 8, which is shown in a perspective exploded view in Fig. 5, comprises two rows of female signal contacts 11, which make contact with the signal contact pins 4 when the second housing 9 is accommodated in the first housing 3. Each signal contact 11 is enclosed by an outer conductor 12 which has contact springs 13 opposed in column direction.

In the inserted state, these contact springs 13 make contact with the ground contact pins 5 of the first connector element 2 located in the same column as the associated signal contact pins 4.

When viewed in the direction of travel, the outer conductors 12 have opposing contact tongues 14, which can make contact with earth contact plates 15 placed on either side of each outer conductor 12 in the second housing 9. The contact tongues 14 located on the insert side in Fig. 5 conduct the current to the inner side. of the outer conductor 12, while the contact tongues 14 at the other end conduct current from the inside of the outer conductor to the ground contact plates 15.

In Fig. 4a, one ground contact plate 15 is shown in perspective. This ground contact plate 15 is provided on the insertion side with female contact elements 16, which cooperate with the columns with only ground contact pins 5 of the first connector element 2. In this way a very good ground connection between the two connector elements 2, 8 is achieved, whereby a favorable current distribution in the outer conductors 12 occurs.

On the side remote from the insertion side, the ground contact plates 15 extend beyond the connecting elements 17 of the signal contacts 11. On these sides, the ground contact plates 15 have connecting elements 18 for connection to a printed circuit board 70 indicated in dashed line in Fig. 1. The connecting elements 17 and 18 may be provided with a press-fit part.

It should be noted that the open space between any two consecutive ground contact plates 15 can be closed by designing a ground contact plate 15 with extensions extending from this ground contact plate 15 to the adjacent ground contact plate 15. As a result, the signal contacts 11 are completely enclosed by ground contact plates.

Since 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, the electrical parameters and thus the behavior of which can be determined as a circuit element. The signal contacts 11 are mounted in the outer conductors 12 by means of dielectric inserts 19. These dielectric inserts 19, which can be injection molded at low cost, have a predetermined dielectric constant. By making more or less large 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 thus, inter alia, the impedance of the transmission line, which is formed by the signal contacts 11 and the outer conductors 12 / ground contact plates 15. In this way a connection can be realized with a constant impedance, whereby no cross-talk can occur between the signal contacts, because each signal conductor is surrounded by a ground conductor.

The connecting elements 17, 18 of the signal contacts 11 and the ground contact plates 15 may also be designed as surface-mounted contact springs, as can be seen from Fig. 2, which shows a connector assembly, the connector element 2 of which corresponds completely to the connector element 2 from Fig. 1 and the connector element 8 is designed with surface-mounted ground contact plates 20 and signal contacts 11. The connecting elements are indicated with 17 'and 18'. Fig. 4b is a perspective view of a ground contact plate 20 which is used in the embodiment according to FIG.

Fig. 6 shows a cross-section of a connector assembly 21, which is constructed essentially in the same manner as the connector assembly according to Fig. 2. In this case, however, two rows of ground contact pins 5 are arranged between the two rows of signal contact pins 4.

In this case, earth contact plates 23, each with a contact spring 18 ', are used, which only make contact with the earth contact pins 5 on either side of the respective signal contact pins 4. As a result, separate earth connections are obtained for the two rows of signal contact pins 4. Due to the wider width of the connector assembly 21, it is also possible to use a printed circuit board 22 of greater thickness.

Fig. 7 is a perspective view of 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 is provided with a connecting element 26 for obtaining a simple connection with the outer conductor 27 of the coaxial cable 25. For this purpose the connecting element 26 is first bent around the outer conductor 27. The otherwise invisible signal contact, which is mounted in the outer conductor 24 by the dielectric insert 19, has a connecting element 28 for connecting the inner conductor 29 of the coaxial cable 25. The connection to the outer conductor 27 and the inner conductor 29 can be soldered be obtained. After connecting the coaxial cable 25, bent-open parts 30, one of which has been omitted for clarity in Fig. 7, can be closed.

Fig. 8 shows a perspective view of a modified embodiment of the second connector element 8 with the housing 9, wherein the outer conductors 12 are provided on the side facing away from the insertion side 10 with an extension 31, which has two ground contact pins 32, which a printed circuit board 33 can be connected. In fig.

8a, one of the outer conductors with dielectric insert 19 and the two ground contact pins 32 is shown in perspective. The ground contact pins 32 may be formed with a press-fit portion. As can be seen from Fig. 8a, the contact pins 32 are diagonal to one another relative to the longitudinal direction of the outer conductor 12. A recess 34 is provided directly opposite each contact pin 32, leaving a hole 35 of the printed circuit board 33 intended for the ground contact pin 32 of an adjacent outer conductor 12.

In the embodiment of the second connector element 8 according to Fig. 8 it is possible to provide each group of one or more signal contacts with a ground connection which is independent of that of other groups of signal contacts. This allows a programmable layout of the ground connections. For illustrative purposes, Fig. 9 schematically shows a cross-section of the housing 9 of the connector element 8, the outer conductors 12 and the inserts 19 being omitted for clarity. In Fig. 9, the signal contacts 11 are indicated by an open rectangle, while the locations for the contact pins 4, 5 are indicated by hatched squares. In the second connector element 8 according to Fig. 8, mass contact plates 36, which are separated for the two rows of signal contact pins 4, are indicated by oblique hatching. These ground contact plates 36 have only one female contact element 16, which can only contact a corresponding ground contact pin 5 of the two outer rows of ground contact pins 5. In the exemplary embodiment shown, insulating plates 37 (indicated at three places in the housing 9 of the second connector element 8) with a horizontal shading), while in the middle row ground contact pins 5 are provided with only one ground contact pin 5 and four non-conductive insulating pins 38 (also hatched horizontally). As a result, the outer conductors 12 of different groups of signal contact pins 4 and corresponding female signal contacts 11 are insulated from each other, so that the ground connection of these groups is made separate and these groups cannot influence each other. By optionally arranging the insulating pins 38 and insulating plates 37 in place of the ground contact plates 36 and the ground contact pins 5 at suitable locations, any desired group of signal contacts with common ground connection can be realized. It is noted that instead of the insulating pins 38, the mere omission of the ground contact pins 5 is sufficient for separating outer conductors 12 lying in a column.

The ground contact plates 36 can also be coated on one side with an insulating layer to achieve a separation between adjacent outer conductors 12. This not only permits separation, but the outer conductor 12 located on the conductive side of the ground contact plate 36 maintains the ground connection through this ground contact plate.

Fig. 10 shows a cross-section of a connector assembly 39, the first connector element 40 of which corresponds substantially to the first connector element of Fig. 1. In this case, however, the contact pins 4, 5 are column-spaced 2 apart. Placed 5 mm apart. The signal contact pins 4 are spaced 4.5 mm apart. Each of three consecutive ground contact pins 5 are combined into a ground contact lip 41 shown in Fig. 12, which can be provided with three connecting elements 42 at a mutual distance of 1.5 mm.

As can be seen from Fig. 10, the connector assembly 39 comprises a second connector element 43, which is provided with two rows of female signal contacts in the same manner as the second connector element 8. The second connector element 43 further comprises an outer conductor 44 and 44 for each signal contact. 45, that of an extension 46, respectively. 47 are provided. The outer conductors 44, 45 are shown in perspective in Fig. 11. The extensions 46, 47 have four connecting elements 48, which can be provided with a press-fit part. The outer conductors 44, 45 further have two contact springs 49 on either side, which make contact with the ground contact lips 41, which adjoin these signal contact pin 4 on either side of the associated signal contact pin 4 of the first connector element 40. As a result, the ground connection is separated per column of signal contacts. When, as in the embodiment according to Fig. 6, two rows of ground contact pins 5 are present between the two rows of signal contact pins 4, each signal contact pin 4 can obtain a separate ground connection.

Although not shown in FIG. 11, the female connector assembly 39 also has each female signal contact mounted in the associated outer conductor 44, 45 by means of a dielectric insert. In Fig. 10 two connecting elements 50 of the female signal contacts of the second connector element 43 are still visible.

It should be noted that in the embodiments of Figures 8 and 10, the signal contacts and the outer conductors of the second connector element are provided with connection elements for mounting in conductive material-coated holes of a printed circuit board. However, in the embodiments these connection elements can of course also be designed as contact springs for surface mounting.

Although in the exemplary embodiments of the invention described above, each female signal contact is surrounded by an outer conductor, it is also possible to place two or more signal contacts within an outer conductor. As a result, twinax or triax compounds with the same favorable properties can be obtained. The connector assembly according to the invention is therefore also suitable, for example, for use in systems that work with ECL circuits.

Fig. 13 shows in perspective an example of an outer conductor 51 of a second connector element, not shown, in which two female signal contacts 52 are mounted by means of an insert 53. The outer conductor 51 is provided with ground connection elements 54, while the signal contacts 52 each have a connecting element 55. Furthermore, the outer conductor 51 is provided with contact springs 56, which make contact with ground contacts of the associated signal contact of the first connector element (not shown). It will be clear that the two connector elements can otherwise be designed in the manner described above.

The described connector assemblies already give a considerable improvement with regard to the high-frequency properties. A further improvement can still be achieved if the signal contacts of the first connector element are mounted in an outer conductor in the same manner as the signal contacts of the second connector element.

In Figs. 14 and 15, a first connector element 56 is a plan view and top view, respectively. sectional view, each signal contact 4 being enclosed by an outer conductor 57 over the portion of the signal contact extending into the insulating material of the first housing 3. The signal contacts 4 are mounted in the outer conductor 57 with the aid of an insert 58. It is noted that also in this case two or more signal contacts 4 may be enclosed by a common outer conductor 57.

The ground contacts 5 of the connector element 56 each comprise a plate-shaped portion 59 which contacts the outer conductor 57 of adjacent signal contacts 4. Here, the outer conductors 57 are provided with a contact tongue 60 at the location of the points of contact, as can be seen in Fig. 16.

Fig. 17 shows a cross-section corresponding to Fig. 15 of a first connector element 61, which is suitable for connection to a dashed line

O

printed circuit board at an angle of 90.

In this case, the outer conductors 57 are provided with an extension piece 62, which, in a similar manner as the extensions 31 of the outer conductors 12, is provided with earth connection elements 63. In this case, the earth contacts 5 are designed without connection elements 6. For clarification, the outer conductors 57 with extensions 62 in FIG. 18 are shown in perspective. As shown in this fig.

18, the connecting elements 63 are arranged in the same manner as the connecting elements 32 of the extensions 31 of the outer conductors 12. Also in this case recesses 34 are used for the connecting elements of neighboring outer conductors. Figure 18 also shows the signal contact pins 4 with their connecting elements 6.

It is noted that in the described exemplary embodiments of the connector assembly according to the invention, the first connector element comprises rows with only signal contacts. However, it is also possible to place a ground contact between successive signal contacts. In that case, the ground contact plates of the associated second connector elements can be omitted so that the ground contacts in a row of signal contacts make direct contact with the outer conductors via suitable contact springs or the like.

With the first connector element 56 according to Fig. 14, it is also possible to make earth contacts between the successive signal contacts.

It is further noted that, for example, U-shaped outer conductors can be used, wherein the successive outer conductors connect to each other, so that more or less closed outer conductors are obtained.

The connector assembly according to the invention can also be provided with signal contacts mounted in the usual manner, which are then of course only suitable for relatively low-frequency signals.

From the foregoing it will be clear that the invention provides a connector assembly, wherein the signal contacts with the associated outer conductors can be regarded as a transmission line with such a geometry, whereby the electrical parameters of the connector assembly can be determined. This makes it possible to match the impedance of the signal contacts to the output impedance of the signal source and input impedance of the receiver.

The connector assembly according to the described embodiments of the invention provides a connection with a predetermined impedance between printed circuit boards or between a printed circuit board and a multi-core cable. The manufacturing costs of this connector assembly are relatively low because all signal and ground contacts and outer conductors can be manufactured by stamping and forming. Both press-fit and surface-mount connections on printed circuit boards are possible. The connection between the male and female contacts is comparable to that of the known connector assemblies, so that the favorable mechanical properties thereof, such as coupling forces and decoupling forces and in particular the tolerances with regard to the mutual positions of the contacts, are retained when used in rack and panel configurations.

The invention is not limited to the exemplary embodiments described above, which can be varied in a number of ways within the scope of the invention.
