Description

The invention relates to a multi-pole connector with a planar filter with a number of capacitors corresponding to the number of signal lines to be connected, a capacitor being assigned to each plug pin / socket of the connector, formed by a first covering, which can be connected to the assigned signal line via contact surfaces, one second covering, which can be connected to ground via at least one edge strip, and a dielectric between the two coverings.

With multi-pole connectors, such as those used for the transmission of digital or analog measurement signals from multiple measurement devices or are used in high-speed transmission of information, there is a need for filtering in order to filter out interfering interference signals. This filtering of interfering interference signals is generally carried out using capacitors, one of which is provided for each line carrying a signal. For this purpose, the capacitors are advantageously combined in planar filters and inserted into the plug connectors, the planar filters being penetrated by the signal lines, and at least one capacitor being provided for each of the signal lines and the capacitors being arranged on a generally ceramic, in particular aluminum oxide, carrier. If the individual signal lines are formed by pins pressed into plastic parts (press-fit connections), soldering these pins to the coating of the signal electrodes that extends into the bushing is prohibited. Such connectors are described for example in US Pat. No. 3,447,104 or EU 0 398 807 A2. In these connectors, planar filters are used, which are usually applied to an aluminum oxide substrate using the screen printing process, the electrodes separated by a dielectric layer on the one hand as a continuous ground electrode and on the other hand in the number of plugs or sockets corresponding discrete, mutually insulated electrodes are printed on the connector. Due to their design, these planar filters have a very low self-inductance, so that their resonance is shifted towards high frequencies, which favors the use of this technology for fast signal transmission.

These planar filters are provided with openings through which the plug pins or the socket are guided, the covering of the associated capacitor advantageously being guided into the opening where the electrical connection to the plug pin or socket is produced by soldering. In some cases, however, prohibits the geometry that the planar filters are used at right angles to the connector pins or sockets. This is where the invention comes in, which overcomes this disadvantage and which enables the use of the planar filter technology which is more advantageous for filtering at a high signal transmission rate, even in narrow conditions, the installation of the planar filter should be simple and economical.

This object is achieved according to the invention by the features mentioned in the characterizing part of the main claim; advantageous further developments and preferred embodiments describe the subclaims.

The arrangement of the / the planar filter upright next to a row of the plug pins or sockets ensures that the planar filter can be accommodated in order to suppress interference between them at usual distances between the rows of plugs or sockets in connectors. This arrangement can be such that each of the planar filters is arranged between two rows of plug pins or sockets or next to two such rows. The planar filter has at least one side, advantageously also both sides, of condensers, the connections of which lead out to contact areas, each of the plug pins or sockets being connected to the associated capacitor via its contact area by conductors or contact tabs which produce a metallic connection and which are advantageously resiliently elastic , either on the contact surfaces or on the plug pin or socket.

A particularly space-saving arrangement is achieved if the planar filter is provided with capacitors on both sides, so that each adjacent row of plug pins or sockets is connected to the contact surfaces of the planar filter in a short way can. With this arrangement, all of the capacitors of the planar filter can also be produced as a series connection of two capacitors, so that the dielectric strength is increased by this series connection. For the ground connection, at least one edge region of the planar filter producing this connection is provided, to which the ground electrode, which is common for all capacitors of the planar filter, is led out.

This area is connected to the general ground, the connection being established by the clamping rails, which mechanically receive and hold the planar filter, and which are then metallically connected to the ground-carrying housing. Another possibility is given by the fact that separate contact lugs are provided which establish the ground connection, possibly to conductor tracks or surfaces of a circuit board which lead to ground potential, or by connection to a plug pin or socket which is connected to ground -Potential lies.

In one embodiment, a planar filter is advantageously arranged between two rows of plug pins or sockets. These planar filters form the filter stage assigned to these plug pins or sockets of these two rows, the planar filter being printed on both sides with capacitors, so that each of the rows of plug pins or sockets the side of the planar filter with their capacitors facing them, with the corresponding plug pins, in a short way or sockets can be connected. The connecting conductors of adjacent plug pins or sockets at opposite points are in metallic contact with the corresponding contact surfaces of the planar filter, so that the filter effect is not hindered. Such double-sided planar filters described here are produced in the usual planar filter technology: on a carrier, generally one aluminum oxide plate, the electrode to be connected to the mass is printed on using screen printing technology and covers the entire surface (almost). A dielectric layer, generally made of high-dielectric materials, is applied to this ground electrode, and then the individual electrodes connected to the sockets as signal electrodes. An alternative embodiment is provided in this case by using a metallic carrier which forms the ground electrode and which, like the applied ground electrodes of the previously described embodiment, has a good shielding effect. Dielectric layers are applied to both sides of this metallic carrier, which are in turn provided with individual electrodes to be connected to the sockets. In both embodiments, a protective cover protects the arrangement from environmental influences and mechanical attacks.

This arrangement also allows the formation of a connector with filters if more than two rows of connector pins or sockets are provided, which may if the number of rows is odd, a planar filter is used for the rest of the row. The ground connection required for effective filtering is established via the ground electrode, which is generally common to all of the capacitors, this ground electrode being led out to at least one of the side regions of the planar filter and being conductively connected there to the housing of the plug connector. The planar filter is arranged so that one of the side pairs of the rectangular planar filter, preferably the narrow sides, is aligned parallel to the plug pins or sockets. The ground electrode is advantageously led out on the long side; this can reduce the self-induction of the ground connection.

In another, in a confined space between the rows of connector pins A preferred embodiment of a planar filter is arranged next to the rows of plug pins or sockets. As in the previously described application, the planar filter here has several rows of capacitors, the number of which corresponds to the rows of plug pins or sockets assigned to the planar filter. Because of these rows of capacitors lying one below the other in the alignment of the planar filter, the connecting conductors to the plug pins or sockets lie on different levels. The planar filter is - just as in the previously described application example - aligned so that one of the side pairs of the rectangular planar filter, preferably the narrow sides, is aligned parallel to the plug pins or sockets.

In this form of application, the planar filter is regularly outside the rows of plug pins or sockets and is located directly on the wall of the plug housing. It goes without saying that a mixed application is also possible in which the planar filter is arranged between two rows of plug pins or sockets and a planar filter outside the rows, with the two rows of plug pins or sockets adjacent to the planar filter this are connected.

An alternative embodiment of the planar filter allows to be arranged between the plug connectors or sockets even when the connector is closely populated; In this embodiment, the planar filter has on one side two rows of contact surfaces which are spaced apart from each other near one of the edges, advantageously the longitudinal edges, these being alternately assigned to the even-numbered and odd-numbered capacitors, so that they are assigned to the even-numbered capacitors Contact areas, for example, along the lower and the odd-numbered Contact areas associated with capacitors lie along the upper edge of the planar filter. If the planar filter is provided with capacitors on both sides, the corresponding rows of contact surfaces are naturally present on both sides.

In order to establish the electrical connection from the plug pins or sockets to the respectively assigned capacitors, the connecting conductors are designed as spring tongues extending from the plug pin or from the socket. These spring tongues rest on the contact surfaces, which for this purpose do not have to be provided with the openings provided otherwise for planar filters used for the purposes of high-frequency filtering for the passage of plug pins or sockets. It is sufficient if the contact surfaces are exposed so that the spring tongues can lie against them, the elastic properties of the material of the spring tongue ensuring the necessary contact pressure. Since the plug pins or sockets are usually made of resilient material, it is advantageous if the spring tongues of the connecting conductors are formed from the side wall of the plug pin or socket. According to a further development, the spring tongues are guided at a preferably acute angle against the contact points of the planar filter.

An alternative embodiment, which can be used in particular in the case of a double-row arrangement of contact areas on one side of the planar filter, has contact tabs on the contact areas which abut on metallic connection areas of the associated plug pins or sockets and thus establish the contact between these and the respectively associated capacitor . These contact tabs can be soldered or inserted into corresponding holes in the carrier of the planar filter, it being understood that the ground electrode is around these holes must be excluded around in order to prevent inadmissible contact with the earth. If the capacitor electrodes, which are connected to the plug pins or sockets, are arranged on both sides of the planar filter, the metal-coated capacitor coatings are also designed here in such a way that inadmissible contacts are prevented. This formation of the metallic supports can be implemented in a simple manner in the screen printing technology used for the production of such structures. This connection technology has the advantage over the connection technology for planar filters arranged outside the plug pin or socket rows that longer contact lugs are avoided and the self-induction on the signal side is thus kept small.

The interior of the connector housing is filled in a manner known per se with plastic inserts, these having longitudinal recesses in the area of the spring tongues. With these recesses the mobility of the spring tongues is maintained, which can resiliently contact the contact surfaces.

In another embodiment, the connecting conductors are designed as contact pins. These contact pins connect the plug pins or sockets to the contact surfaces of the respectively assigned capacitor of the planar filter. These contact pins are advantageously in conductive connection with the plug pins or sockets and are connected to the contact surfaces of the planar filter. They are preferably made of a resilient material and are generally at right angles to the plug pins or sockets. In an advantageous embodiment, the contact pins are soldered to the planar filter. In another embodiment, in which the planar filters provided with lead-through openings are used, the contact pins are introduced, preferably soldered, into openings provided in the planar filter.

In order to suppress leakage currents and to prevent flashovers, the interior of the connector housing is filled with insulating plastic inserts in a manner known per se. These plastic inserts form a stacked layer formed from several layers, at least one of the layers having channel-shaped recesses leading to the openings for the passage of plug pins or sockets for receiving the contact pins. These are designed as flat metal strips that are inserted into these trough-shaped recesses in such a way that they protrude into the through openings provided for receiving the shafts of the plug pins or the plug sockets and are flipped over when the plug pins or plug sockets are inserted, and thus with metal by squeezing be brought into contact with them.

If two rows of plug pins or sockets are supplied by a planar filter arranged laterally next to the rows of plug pins or sockets, it is advantageous if the contact pins run in different planes, so that the one row in one plane and the other row in are arranged on a second level. For this purpose, two of the layers of the stacking layer then have channel-shaped recesses, these being guided as far as the assigned through openings for the plug pins or sockets.

Figure 1 shows a plan view of the connector 1 with the housing 2 and the sockets 13, which are arranged here in two rows. A planar filter 16 is inserted between the two rows of sockets 13, the narrow sides of which are inserted in clamping rails 5. The narrow sides of the planar filter 16 provided with the ground contacts 16.1 are held mechanically by the clamping rails 5, on the one hand, and on the other hand they are led out via the clamping rails 5 and electrically connected to the connector housing 2 which is at ground potential. The sockets 13 are fixed in the housing with anchor tabs 14 which engage behind recesses in the wall of the housing 2. The outward-pointing anchor tabs 14 serve as holders. The inward-pointing anchor tabs 15 rest on the contact surfaces of the planar filter 16 and thus establish the electrical contact with the capacitors of the planar filter 16, and since the planar filter 16 is fixed in the clamping rails 5 they also contribute to the fixing of the socket.

Figure 2 is a section along the section line II-II (Fig. 1) and clearly shows these conditions: The in the housing 2 of the Connector 1 inserted sockets 13 have outwardly spread anchor tabs 14 which engage behind recesses 2.1 and thus secure the inserted sockets 13. The inward spread armature tabs 15 rest on the contact surfaces 16.2 of the planar filter 16, whereby the conductive connection to the capacitors of the planar filter 16 is established. Since the planar filter is manufactured in thick-film technology and consists of a carrier 17, which is generally made of aluminum oxide (or a metallic carrier 18), on the layers 17.1 and 17.2, which are generally conductive in the screen printing process, between which at least the capacitors are formed a dielectric layer 17.3 is provided, the layer structure being covered with a protective covering 17.4, it is possible to provide these conductive layers 17.1 and 17.2 forming the capacitors on both sides of the carrier 17 and to keep the connections free from the insulating cover 17.4 , to form the contact surfaces 16.2. The connector 1 is closed by an integrally molded or subsequently inserted plastic piece 2.2 (which is not shown in FIG. 1) which is provided with conical recesses 7 for suppressing leakage currents, in which the conical approaches 8 of the mating connector engage and so increase the length of the crawl. This insert is further provided with a one-piece molded or inserted strip-like formation 2.3 which holds the planar filter 16 in position.

FIG. 3 shows a section through a plug connector 1, shown as an adapter plug connector with four rows of plug pins 12, which corresponds to the section in FIG. Here, the housing 2 of the connector 1 is formed from sheet metal, with plastic inserts 6 filling the interior of the housing 2. In the planar filters 16 used here, the long sides are provided with the ground contacts 16.1. These long sides are held by clamping rails 5, which are metallically connected to the housing 2 of the connector 1 and via which the electrical ground connection runs. To accommodate the conductive connections between the plug pins 12 and the sockets 13 with the contact surfaces 16.2 and 16.3 of the planar filter 16, these plastic inserts 6 have guide channels as channels 9 into which the contact webs 10 are inserted. These protrude inward in the area of the plug pin / bushing and are flipped over when this plug pin / socket combination is inserted. Since the lead-through openings in the plastic inserts 6 are made to measure for the plug pin / socket combination, the folded parts of the contact webs 10 are pressed against the outside of the plug pin / socket combination, so that the contacting is flawless. The end (s) of the contact web (s) associated with the planar filter (s) are in conductive connection with the contact surfaces of the planar filter 16. Here, planar filters 16 are advantageously used, which have a lead-through opening 16.3 for each of the capacitors in the customary design, it being understood that the capacitors can be arranged on both sides, either to increase the capacitance or to increase the dielectric strength. Because of the lead-through openings 16.3, each of the capacitors can be reached, the ends of the contact webs 10 advantageously being soldered into the lead-through openings 16.3 of the planar filter 16. The contact webs 10 are bent so that an existing dimensional difference between the parting plane of the plastic inserts 6 with the guide grooves 6.1 or the guide channels in a compact plastic block and the through openings provided in the planar filters 16 is bridged, whereby it is also self-sufficient understands that instead of the stacked layer of the plastic inserts 6, a compact block can be used, into which the lead-through channels 6.1 for the contact webs are drilled, which are then advantageous than in the area of these lead-through channels Round pins are formed, while the part of the contact web 10 protruding into each feed-through channel for the plug pin / socket combination is flattened. In the embodiment shown in Figure 3a, which corresponds to the representation of the connector in Figure 3, two planar filters 16 'are used, which are arranged here between the two pairs of rows of the sockets 13. The planar filters 16 'used here are held in longitudinal contact rails 5, which establish the ground connection via the metallic housing 2; they have two rows of contact surfaces 16.2 ', which are arranged in rows along the two edge regions of the planar filter 16'. Each of the contact surfaces, as shown enlarged as details, is provided with a contact tab 10 'which is soldered into a bore 16.3 in the carrier 17 and is thus connected to the associated capacitor covering 17.1 which is at the signal line potential. The ground electrodes 17.2 lying at ground potential are left out in the region of this bore 16.3. In the two details shown, the assigned capacitor is shown on the left of the rear of the planar filter (seen from the contact tab) and on the right on its front. After assembly of the connector 1, the free end of the contact tab 10 'bears against the associated metallic socket 13 (shown here). With this design, the planar filter 16 'can be kept very flat, so that it can also be used with tightly populated connectors. The arrangement of the contact lugs 10 'is almost completely symmetrical and these can be kept short, so that the undesired self-induction can be small and their distribution can be kept even.

FIG. 4 shows a schematic top view of a connector 1 with two rows of sockets 13, each row having five, without restricting the invention thereto, it being also goes without saying that these sockets 13 can be set to "gap". The planar filter 16 is drawn in with dashed lines and, as shown in FIG. 2-, is located between the two rows of the sockets 13. The drawn, multiply jumped section line VV indicates how the connector 1 is cut in the illustration in FIG. 5.

This Figure 5 shows the connector 1 in the left area in an external view. The sockets 13, which are concealed in the depth, are also indicated by dashed lines, as is the planar filter 16 located in the middle. The projection in the middle area reveals the socket 13 arranged in the center, which, with spring clips 15.1 of the inward-pointing anchor tabs 15, as contact tabs on the contact surface 16.2 of the Planar filter 16 abuts and thus directly via this with the associated electrode of the capacitor of the planar filter 16, which can be recognized directly on this cut only on both sides of the socket 13, which is inserted into the shape of the housing of the connector 1. To the right of this central area, the cut has again jumped so that the side wall of the planar filter 16 is now visible with a contact area 16.2 assigned to this area, which is held in position by the strip-like hold-down device 2.3 molded onto the plastic insert 2.2. The socket 13 hidden in the row behind is indicated here by dashed lines. The following jump in section line V-V leads into this row of sockets behind, the socket itself not being shown; The recess 2.1 can be seen, in which the outwardly pointing anchor lug 14 (FIG. 2) engages for fixation.

FIG. 6 shows a planar filter 16 schematically in view. The longitudinal side edges are covered with the contact surfaces 16.1 for the ground electrode / electrodes, which after insertion in the connector 1 with the clamping rails 5 (Fig. 3) are conductively connected. The contact surfaces 16.2 'which are brought out are arranged in two rows near the longitudinal side edges, in which the contacts themselves are provided alternately, so that the distances between adjacent contact surfaces 16.2' are twice as large as the distances between the associated plug pins 12 or sockets 13 6a and 6b finally show cross sections through the planar filter 16 itself. The embodiment according to FIG. 6a is essentially formed by the insulating, generally aluminum oxide support 17, which has on both sides a first, continuous, conductive layer 17.2, which as electrode at ground potential is conductively connected to the outer contact surface 16.1; this flat double electrode forms a shield that shields the two rows of connector pins 12 and sockets 13 against each other. A non-conductive, dielectric layer 17.3 is applied to these conductive surfaces 17.2 as the dielectric of the capacitors; here, as a rule, high-dielectric materials are used, which are known from thick or thin film technology, for example barium titanate. The individual capacitor coverings 17.1 to be brought into conductive connection via the contact surfaces 16.2 with the plug pins 12 or sockets 13 are applied to this continuous dielectric. A protective coating 17.4 covers the entire planar filter 16, which is usually produced using screen printing technology, and offers protection against environmental influences or mechanical influences. FIG. 6b shows another construction of such a double-sided planar filter 16: Here, the carrier is a metal plate 18, onto which the dielectric 18.3 is applied, which in turn carries the individual capacitor electrodes 18.1. The continuous ground electrode is omitted here, it is formed by the metallic carrier plate, which has the necessary conductivity and shielding ability.
