The invention relates to an electrical connector for passing signals and / or supply voltages through the housing wall of an electrical device, with at least a contact held by a plug body and a shield.

The invention is particularly concerned with those connectors that have a variety of electrical Have contacts and of those without concessions with regard to the number and size of the contact sockets and pins a significant proportion of unwanted external RF signals and stray fields reflected or derived from ground and thereby reduced to a value at which the noise or interference no longer significantly disturbs the reception of the useful electrical signals.

Plug-in connections with a large number of contacts that have a jackscrew means to the Securing and poling the connector body have a large number of closely spaced contact pins or contact sockets are known from US Pat. No. 3,281,761. Through the invention are, however, with such connectors without reducing the space for the contact pins and contact sockets are available, filter, shielding, Isolation and grounding elements added, the unwanted noise or unwanted Signals, especially at high frequencies, derived or reflected to ground, whereas the desired signal voltages are the contact pins and Contact sockets of the connector can pass.

Known devices attempt to address the problems in less advantageous or unsuitable ways solve by electrical filter networks, which consist of discrete elements, i.e. capacitors, resistors and / v-Jer induction coils, Make use or provide larger connector parts and in the additional created in this way Place special filters. Furthermore, the known arrangements do not have any removable ones Plug parts with interchangeable contact pins and contact sockets on, and they reflect or do not effectively ground the unwanted signals. They do not have any shields around the structures Completely isolate from unwanted RF energy. The known plug connections solve the problems not where removable contacts are needed that are only a small distance apart to have. They require additional, space-consuming and / or expensive HF sealing arrangements, to reduce HF leakage paths. They do not meet the interchangeability requirement of Parts and easy adaptation to external equipments, housings or frames of various Have thickness without this being associated with a substantial loss of shielding effectiveness.

The invention is based on the object of creating a plug connection which can be connected to a large number of different electrical devices is adaptable and without requiring additional space in the plug-in body would provide substantially perfect shielding, significant amounts of noise signals of certain frequencies and significant portions of noise signals of certain frequency ranges, dis are located on the lines that connect the shielding Penetrate the wall, filter it and divert to mass.

This object is achieved in the case of an electrical plug connection of the type mentioned at the outset according to the invention solved in that it auiweisl an intermediate plate, which consists of a deformable, for RF noise signals a certain frequency range is made of conductive material and with the shield is connected, and that with Hern contact and dei Intermediate plate a filter is coupled to a shunt for the noise signals from the contact zui To create shielding.

Although it is already known, a coaxial connector rni1 has the central connector pin with the shield connecting conductive plate to be provided, but this plate is used to terminate the coaxial line at which no signal or supply energy is to be passed. In this known arrangement So it is not a plug connection for passing signals and / or Ver supply voltages, but rather a termination resistor for coaxial lines (USA.-Patentschrift 2 761 110, Fig. 5, 9). Will, as it usually de Case is, the conductive plate of the terminating resistor

The resistance is given by the wave resistance through the shield. In both cases is still If the coaxial line is the same, there will be a lateral compression because the entire diameter of the energy supplied to the hole-conducting plate is a critical amount smaller than that needs. For the use of an intermediate plate diameter of the filter contacts. At the first exit conductive material in the case of plug-in connections for example, the compression is passed through to the plat of signals and / or supply edges through the flange mounting in the However, tension can be caused by this known construction, such as the depth of the cover hood tion do not offer any suggestion, because its just another to the inner surface of the upper wall is smaller than that Task is based, namely the formation of the thickness of the plug body and the attached Final resistance of a coaxial line. io sealing plate.

The seal can be achieved. The contact pins and contact sockets and the plug body are grounded by a device that can be in place by a surrounding, serving shielding cap. In a first spring embodiment having outwardly protruding sections of the invention has the shielding member to be held, and it provides the invention the cut off a flange, and it's a bearing and iso- *> Space in front of which is provided for inserting a tool to the lation block with a protrusion that compresses the protruding portions of the is provided with a conductive surface and by spring member when dismantling the contact ereiner a precisely fitting opening of the cap in this way. For this purpose is the one given above it is taken that the surface of the projection is provided for space due to that the area of the deformable sealing plate is larger than the diameter of the holes in the plug body lies. In a second embodiment, what surrounds is the outer diameter of that of the invention HF shielding the sealing plate and the plug-in filter contacts. The size of the holes body which is designed so that it fits with the housing of the sealing plate into which the contacts are inserted walls, frame or chassis parts of the electrical will result, as the elastic material after Device, which can have different strengths, must be pressed outside, a press fit (interbinable is.

In the first exemplary embodiment, filter-sensitive pens are provided. The good electrical connector pins or filter contact sockets are provided to prevent the passage of HF energy on the other hand, in the case of the second exemplary embodiment, contact through the holes that are aligned with one another. Further pins, sockets and filter intermediate contacts are desirable features that the into the aligned holes of the seal, sealing or intermediate plate according to a method and the plug body are inserted.

it is clear that the connector body is oppositely 22 is dimensioned so that the polarity and most secure sides of the housing wall complementary alignment or connector clamping screw 25 are formed therein. For example, since the plug body 21 has a press fit. The metal layer 30 of the projection 31 of the first illustrated embodiment one and the conductive intermediate plate 22 form parallel projection 21 α , the connector body 25 provided on the opposite 5 low-resistance grounding paths from the connector screw side of the housing wall to the shielding cap 23, so that undesired 57 (see Fig record.

The contact will be. Furthermore, the metal layer 30 improves the bushings 29 can optionally either reflect certain Rauscbirequenzen in the plug. Therefore, body 21 or the plug body 57 used in the arrangement according to the invention will be undesirable, and it is then the matching contact signals that would otherwise pass the plug screw 25 pins 70 accordingly either in the plug, in addition to the unwanted frequency body 57 or the plug body 21 is used to establish a continuous connection zen of the contact sockets 29, which are derived from ground. Likewise, j 5 or reflected, short-circuited to ground, the plug body 21 can instead, as shown, be on or reflected. The assembled subassembly of the plug of the inside of the housing wall at its external connection is fastened to the housing 20 or an end and accordingly the plug body 57 instead of the speaking frame or chassis with the two screw bolts 27 on the outside on the inside of the housing wall. After tightening the be arranged. 20 screw bolt 27 is an electrical contact with which either the contact pin 70 or the conductive edge, which is at ground potential, the contact socket 29 is designed as a filter contact, section 34 of the housing 26 from the flange 35 is provided with a filter because it can run along the circumference the shielding cap 23 can be done attenuation or reflection at each end. posed. The grounding unwanted Rauschfrequen-Optionally, (zen see 35th for example, g between 30 MHz and 10 GHz F i. 1) and a regular plug located at one or the other side of Ge, by the action of the upper wall 36 häuses 26 be provided, in which a reinforced HF shielding cap 23, which dispenses with the deschenplatte 22 made of conductive material, worforraable conductive intermediate plate 22 in transverse directions, because the filtering only needs to exert a pressure at one point when the Bolts 27 take place. Although any arrangement is possible, 30 are tightened to press the flange 35 against the edge, for the sake of simplicity, usually all the contact sections 34, because the depth of the cover sleeve 29 in the one of the connectors cap 23 from the inside of the top wall 36 to and all the contact pins 70 in the other of the connection to the outside of the flange 35 is less than the extension pieces used. Because of the width of the hollow thickness of the intermediate plate 22 and the body section projection 56 and the 21 c inserted in this projection in the unsecured state and therefore the engaging projection 21 α are the unmarked side of the upper wall 36 against the pin flanges of the plug body 57 in the distance rule plate 22 is pulled. A peripheral electrode is located on the surface of the housing wall 26 which is in shear contact with the edge portion 34 of the housing on the side of the edge portion 34 opposite. 26 is by the pressure connection of the outer As shown in FIGS. 1 and 4 can also be seen, 40 flange 35 of the shielding cap 23 with the edge the assembly of the components of the plug connection in the section 34 and the metal layer 30 of the insulation way that the conductive intermediate plate 22 ensures blockes24. A fully first peripheral c on the surface of the body portion 21 contact which contacts substantially all the points of the plug body is glued 21st Then, through the shielding inclusion of the upper one, the polarity and safety device 25 is achieved in the wall 36 of the shielding cap 23, which uses a glued assembly 21, 22. The shielding cap 23 is then applied to the one-piece elastomer or rubber assembly by applying pressure to the intermediate plate 22 or the layered intermediate plate with its central hole screw bolt 27 is tightened. The intermediate 33 over the threaded bolt 32 of the 50 plate 22 or 82 is deformable to such an extent that the polarity and safety device 25 is pushed. that it engages due to the critical dimensions, shape of the projection 31 of the insulation block and fastening of the elements tightly to the inner 24 with the metal layer 30 in the rectangular opening side of the shielding cap 23 and on this 20 of the shielding cap 23, causing a rotation "In this way, complete peripheral contact of the block 24 with respect to the arrangement is prevented, ie a perfect mass potential is prevented the assembly of this coming shielding is completed by the metallic Ab-part of the connector Since the size coverage, which results from the HF-Abschjrmkappe and that of the Vorspnmges 31 with its metal layer 30 larger conductive intermediate plate 22 or 82, is on one than the depth the opening 20 in the shielding cap 60 is reduced to a minimum or completely eliminated In the intermediate, closely adjacent holes 37 in the deformable layer 22 a pressure is exerted, the conductivity-conducting intermediate plate 22 or 82 are then improved on the intermediate plate, as will be explained later on the feeder contact sockets 29 or for reasons of clarification.

Instead, the central hole 33 β of the conductive intermediate plate can also equip the holes 37 with filter contact pins 70.

be filled. The filter contour sockets 29 and filter contact lifts 70 fit into holes 37 and 86 of deformable intermediate conductive plate 22 and 82, respectively with one? Press fit into it.

The resulting compression of the conductive material at the periphery of the holes 37 or 86 against the bays 29 or pins 70 reduce any possibility of RF energy passing through to ground Serving intermediate plate 22 or 82 through an HF line on the wire and contact 29 or 70 along to a minimum.

At the point where a socket 29 or a pin 70 horizontally in the intermediate conductive plate 22 or 82 rests, the rubber or the elastomeric material and any intermediate layers that may be present become 83 or 84 is printed to the side through the contact 29 or 70, and it becomes the material of the intermediate plate 22 or 82, making the plate more conductive.

The shielding cap 23, which is designed so that it ensures perfect shielding and grounding, with its flange both leads to a better electrical connection because of the flat Flange section and to an increased mechanical stability that the cap before a mechanisehen Arching protects. The contact along the entire circumference on the base of the shield cap 23 is important for a good grounding of the occurring HF signals. The distance between the base the shielding cap 23 on the flange 35 and the inside of the top wall 36 is critical to the Top of the deformable intermediate plate 22 or 82 applied the correct pressure and at the same time the connection of the shielding cap 23 to the housing 26 is guaranteed. That way becomes a good electrical connection to each of the filter capacitor sections 63, intermediate plate 22 or 82 and the shielding cap 23 promoted. This feature also causes the material of the intermediate plate 22 or 82 is pressurized both laterally and vertically, which is necessary for a good Contact between the intermediate plate and the shielding surface for deriving the signals is achieved. In this way becomes a good electrical ground without further changing the physical parameters of the connecting contacts enables. Furthermore, a filtering out of undesired frequencies is achieved in this way.

The flexibility of the intermediate plate 22 or made of rubber or an elastomer Layer 84 in the vicinity of the hole and the interference fit ensure that all parts of the intermediate plate 22 or 82 around a hole 37 with the electrode 63 or 97 on the filter of the contact socket 29 or des Contact pin 70 are in contact. This also eliminates the possibility of an HF leak through the Intermediate plate 22 or 82 by RF propagation on the contact socket 29 or the pin 70 and reduced or eliminated along the unspecified wire. When squeezed properly the intermediate conductive plate 22 or 82 effectively shorts out many of the noise frequencies which should be earthed, and if they are of the correct thickness or contain a layer of metal, other noise frequencies are reflected from it. There continues to be almost all surface sections of the Zwiselenplatte 22 or 82 from the metal layer 30 of the insulation block lying within the shielding cap 23 24 can be contacted after the expansion without gaps can form is this ensures an optimal shielding effect

FIG. 2 illustrates a first preferred embodiment of a feeder socket 29. The filter contact pin 70 of the first preferred embodiment is shown in FIG. 5 shown These filter contacts according to the F i g. 2 and 5 represent modifications of commercially available contact pins and sockets. As can be seen from FIG Form tubular π-filter 59. Two separate metal layers 64 are applied to the inner surface of a ceramic tube 62, which form the inner layers of two capacitors C1 and C 2 , while an outer metal layer 63 forms the outer layer for the two capacitors C1 and C 2 (see FIG. 3). . The tubular ji filter 59 accordingly comprises the inductance which is formed by the ferrite beads 47, and the two capacitors C1 and C 2 according to FIG. 3, which consists of the common occupancy that is formed by the conductive outer electrode 63 of the filter 59, and the inner occupancies that are formed by the inner conductive layers 64. The dielectric consists of the ceramic tube 62. The electrical structure is shown in FIG. 3 shown. The resistance in FIG. 3 illustrates the resistance of the inductor at the frequencies of the RF energy en route laterally through the beads 47. The outer coating 63 shown in FIG. 3 is shown schematically as two interconnected and grounded coverings is achieved by applying the coating to the entire surface facing the inner coverings 64. The inner coverings 64, the ceramic tube 62 and the outer cover 63 accordingly form the two in FIG. 3 shown capacitors C1 and C2, which together with the inductive reactance or the resistance of the ferrite beads form the jt filter 59. The inductive reactance or impedance of the filter is about 50 ohms at a frequency of about 100 MHz. The capacitors C1 and C2 each have a capacitance of about 750 pF. Filters as just described are commercially available.

The filter 59 is made with the aid of the elastomer or rubber intermediate plate filled with a conductive material 22 (see FIGS. 1 and 4) or the layered intermediate plate 82 (see FIG. 10). the The assembly of the filter contact socket 29 is completed by applying hard solder with which the tubular filter 59 is held in place. The solder is melted into solder sections 48 and 49, which result in a permanent structure. Sections of the outer covering 63 of the capacitors, the solder sections 48 and 49, part of the reduced pipe section 61 and that of the reduced pipe section 40 adjacent pipe section 41 are provided with a dielectric insulating layer 56, for example an epoxy resin layer. Accordingly, only the middle, preferably gold-plated, section is the outer covering 63 of the filter exposed and connected to the conductive intermediate plate 22, which the Forms the grounding path to this capacitor assignment.

For example, will. Furthermore, the thickness of the intermediate plate 22 One that vulcanizes at room temperature can be large enough that the silver or other conductive rubber by impregnating with a silver filler 55 the filler in a displacement compression material can be made conductive.

Accordingly, the size of the Normally there is an attenuation of 40 db for the Holes in the intermediate plate critical because if the purposes where plug-in connections according to the He-Koatakt sockets 29 or pins 70 through the holes 15 can find application, already assume 37 or 86 are plugged, the contacts on the bar. The problem becomes increasingly difficult with mitt silver layers or the other conductive material at lower frequencies in the range of about 1000 to the intermediate plate must exert such a force, 2000 MHz (1 to 2 GHz). At 1 GHz, they wander a ground contact, that is to say a contact to the chassis without a filter 59, was about 50% of the undesirable is guaranteed. The holes 37 or 86, however, are allowed to introduce noise through contact into the device. At about not so undersized that it practically finds 10 GHz because of the reflection of the RF energy it is impossible to break the contacts without breaking the noise no propagation into the electrical remote or the filter contact pin 70 or the filter device instead. At 1 GHz it becomes 50% of the noise Contact socket 29 transferred into the intermediate plate 22 or 82, and it must be the RF signal from the to be permanently embedded. as filters are transmitted, must be well grounded.

In Fig. 10, an embodiment of the intermediate is between 30 and 500MHz, the filters are 59 and Intermediate plate shown, the deformable conductive intermediate plate 22 in the case of a plug-in connector binding according to the f i g. 1 to 5 as well as eliminating the noise at these frequencies Plug connection according to FIGS. 6 and 7 apply effectively through the compression applied to the press fit and which can find a number of rubber or 30 of the filters 59 in the holes 37, tightening the an elastomer consisting thin layers 84 shielding cap 23 with the help of the bolts 27 to the and alternating metal foils or layers of metal housing and tightening the insulation block 24 83 exists, which are connected to the intermediate plate 82 by means of the plug screw 25 on the intermediate plate are connected. Holes 86, which is due to the holes 37 of FIG. A certain attenuation is so without Corresponding to the intermediate plate 22, the metal layer 30 on the insulation block 24 is also provided here and dimensioned so that it acts as an interference fit. The metal layer 30, however, has a distinct one Filter contact sockets 27 or pins 70 or not improve the damping result. In the area blind contacts shown. The metal foils between 8 and 10 GHz and above are mainly used or metallic coating layers extend:, xh borrowed no propagation on the contacts instead, into the holes 86 to the outer coverings 40 because the energy is totally reflected. A difficult one 63 to contact the filter 59. A characteristic of the problem are the noise frequencies between alternating metal layers and with a non-500 to 8000 MHz. In this area is about Elastic layers filled with conductive material withstand 50% of the energy along the lines in that several parallel paths contribute to the shielding, and the filter effect is inadequate because mung 23 are available. 45 the rubber with a conductive filler

The metal layer 30 of the insulation block 24 lies between the plate 22 and the filter 59 in the transverse direction at the deformable conductive intermediate does not form a sufficiently good grounding. Because of the shank plate 22 or 82 and expresses the intermediate phenomenon of tension equalization when under pressure plate together in the transverse direction. This pressure gum is actually attached to the adjacent straps in the case of the intermediate plate 22, the 50 th walls of the filter 59, that is to say the condensation conductivity to ensure this plate. To this satorbelag 63, and in the insulation block 24 The purpose of the projection 31 in the transverse direction is only very close to an adjacent part of the intermediate plate Thickness, which is greater than the depth of the opening 20, so a thin conductive layer is present. At frequencies that before tightening the clamping nut 28 tin is above 500 MHz, the one in the intermediate plate 22 is preset Distance between the bottom surface of the 55 existing conductive layer too thin for maximum Block body 50 and the top wall 36 of the ab- effect and there is a certain thickness of the umbrella cap layer 23 exists. After tightening the necessary RF reflection and RF clamping nut 28 will use the intermediate plate 22 or 82 to achieve grounding. In order for an attenuation of the HF-compressed and thereby the block 50 to the noise between 500 MHz and 8 GHz to concern umbrella cap 23 brought to bear. In addition, carry 60 is either an intermediate plate after becomes a conductive ground path through the compression F i g. 10 made up of several alternating layers Sion of the intermediate plate 22 or 82 through the Ab- made of an elastic material and thin, Aufetraschirmkappe 23 manufactured. The shielding cap 23 or made of foils metal layers is fixed in place with the help of the screw bolts, or the attachment of a metal layer clamped, which is suitable for the intermediate plate 22 or 82 65 30 on the insulation block 24. The applied and the arrangement of the layer or metal foil comprising the plug body 21 should preferably follow fasten the housing 26. The tightening of the screw bolts at the edge that make contact with the filters 27 has a compression pressure on portions of the holes extending. The number thinner

initial path by the conductive layers or foils 84 on each of the conductive material structures Elastomer layers are formed, which extend to the air shielding cap 23, serve the purpose This compressible degree along the side of the filter 59. The isolation block 24 prevents further work the contact sockets 29 or pins 70 to bend in the entrance area of the connector and also causes the material of the intermediate plate 22 or 82 to be compressed.

It should therefore be noted that even with compression, by engaging the contacts with a An interference fit is achieved in the holes 37 or 86 of the deformable intermediate conductive plate 22 and 82, respectively, and with the compression exerted by the shield cap 23 and the underside of the protrusion 31, the conductivity of the intermediate plate in the medium frequency range between 500 MHz and 8 GHz is not sufficient. For example, a damping of only about 20 db can be achieved instead of the required attenuation of 40 db. Because of this, will either the conductive layer 30 is provided to improve the conductivity, or the intermediate plate is used 82 composed of the elastomer layers 83 and conductive layers 84, in particular foils. Both measures can also be taken to increase the conductivity. The elastomer layers 83 and the metal layers 84 are provided with holes 86 for receiving the contact sockets 29 or pins 70 provided. So is to find a more conductive path to the shield 23 and on to earth to create the underside of the projection 31 of the insulation block 24 coated with silver or on provided with a perforated conductive layer 30 in another way. The conductive layer 30 can, for example prepared by spraying or rolling silver on the protrusion 31 or by electroplating will.

In the embodiment according to FIGS. 1, 4 and 5, the projection of the insulation block 24 is thicker than the opening 20 of the shielding cap 23, so that it is out of the opening 20 of the shielding cap downwards protrudes, that is to say protrudes beyond the inner surface of the wall 36 and compresses the intermediate plate 22. The surface of the projection 31 is also provided with a highly conductive metallic coating or covered with a metallic foil 30. The projection 31 is made thicker than the opening 20 is deep so that when the polarity and safety device 25 is tightened against the deformable, conductive intermediate plate 22 a pressure is applied. When tightening the polarity and safety device For example, a tension force of about 140 cm / g can be applied. Layer 30 and / or the intermediate plate 82 according to FIG. 10 form a structure that prevents the reflection of higher noise frequencies, such as 8 to 10 GHz, so that such high noise frequencies do not get into the electrical device be transmitted.

It is important that the contact sockets 29 and contact pins 70 are removable. For this reason, the retaining clip 46 and the corresponding structure of the reduced sleeve 45 of the tapered stops 43 and 44 and the other sections of the contact sockets 29 and pins 70 have such a shape and size with respect to the size of the holes 37 a of the plug body 21, the holes 37 b of the insulation block 24 and the holes 37 of the intermediate plate 22 or 82 and the corresponding holes in the connector parts according to FIGS. 5 and 6 that between the socket 29 or the pin 70 and the Ϊ «ch 37 a space remains for a tool, not shown,

that is required to move the outwardly protruding portion 66 of the retaining clip 46 away from the stop 43 in to press a hole section 65 delimited by two conical surfaces in order to reach the contact socket 29 to be able to dismantle. The same applies to corresponding

The corresponding elements of the arrangements according to FIGS. 5 and 6, so for example the retaining clip 96 in that of two conical surfaces delimited hole section 79 of the Kontaktstiite 70 having connector part F i g. S. For these reasons, there is a loose connection

required, which leaves space for a tool between the hole 37 α of the plug body 21 and the outer surface of the filter contact socket 29 or the filter contact pin 70. The intermediate plate 22 or 82 is provided with holes 37 and 86, the diameter of which is smaller than the diameter of the filters 59 or 97. However, since the intermediate plate is flexible, the filters 59 and 97 are inserted into the holes 37 and 97 respectively. 86 not damaged This relationship of the diameter of the filter outer surfaces and the

«5 holes of the intermediate plate has one under pressure, but flexible fit of the filter result if they are with the walls of the holes 37 or 86 are in engagement in the intermediate plate, so that not only an electrical connection of the external occupancy 63 of the filter capacitor to ground to attenuate high noise frequencies and unwanted signals, but also a resilient but firm hold for the otherwise loosely inserted sockets 29 or pins 70 is achieved that damage the sockets or

Pins prevented. The sockets 29 and pins 70 have dimensions such that they are inherently extremely delicate. Because of the resilience, spring force, flexibility, The compliance and resilience of the material from which the deformable intermediate conductive plate 22 or 82, however, the pins 70 or sockets 29 are held firmly in place. aside from that the pins 70 and sockets 29 are resiliently held so that any impacts from the resilient and elastic material of the intermediate plate 22 are received and removal is also possible. This feature of making good electrical contact and still removing the pins 70 or sockets 29 is possible without a loss in terms of the pin or socket density and that furthermore the holes in the intermediate plate large enough and the intermediate plate thick enough and with the right one Made to avoid misalignment of the sockets or pins is a feature of the hardness present invention.

There is often the requirement that a certain number of connections per cm ² must be accommodated in the allotted space. Furthermore, the connection of the pins should not be permanent, but the pins and contacts must be removable for exchange and for other reasons. By using the intermediate plate 22 made of a rubber or elastomer of suitable hardness impregnated with conductive material, the guide of the balls in adequate numbers and size or another suitable conductive material, the advantages of a good electrical connection, vibration damping and a considerable reduction in the requirement are achieved to close work

Humidity and other harmful environmental-tight tolerances have a detrimental effect on the transmission of the signals and feed chip filter contact pin 70 or the filter contacts on the outside diameter of the path. The other elements socket 29 with respect to the hole 37 α of the plug of the part of the connector body containing the pins 21 is provided so that the filter contact 5 comprise a socket made of an elastomer or rubber 29 or the pin 70 tightly in the Hole fits, standing conductive intermediate plate 92, an insulation block 94 serving as a Konjedoch for dismantling and assembly purposes the single-stroke carrier and a removal of a tool enables without the shield cap 93. As with the contact sockets 29 by the physical properties of the pin IQ having part of the plug connection also exists or the socket 29 can be significantly influenced. The intermediate plate 92 made of a conductive elasto-tolerances in relation to the conductive rubber spacer, which is provided with a conductive filler, plate 22 are, however, much less critical. Unless an intermediate plate 82 is used, this enables temperature variations and variations. The plug body 57, like the block 94 which is used as a pin in the manufacture of the pins and the rubber carrier, consists of a non-conductive intermediate plate in terms of thickness, but not a dielectric. The isolation block 94 is accessible with one of the holes. The compression of the rubber provided a metal layer not designated, which corresponds to the or elastomer of the intermediate plate 22 through the metal layer 30 of the insulation block 24, adjacent occupancy 63 of the filter capacitor. here is a filter contact high frequency signals to ground and prevents the ao pin 97 provided.

Bushings 29 and pins 70 can be easily inserted and removed. The contact socket 29 or the pin can be removed. A contact socket 29 is inserted, tes 70 takes place with the aid of a simple, not in this first the socket section 67 by the provided extraction tool. The tool has successive holes 37 b, 37 and 37 a on a cylindrical sleeve which is pushed around the socket. The holes 37 b in the insulation block 24 section 67 and the sleeve section 38 of the contact wheel of the section of the holes 37 α in the plug body fits the socket and the flange 66 of the resilient retaining 21, which are adjacent to the intermediate plate 22, have clips 46 so that the Retaining clip in the one diameter that is larger than the largest space is pushed back, the reduced diameter of the socket 29 or pins 70, so that a 15 cut 45 surrounds the socket. The tool indicates pushing through is possible. The sections of the socket continue to have a central retractable and a-29, which are inserted first, namely the tubular pin that adorns the contact socket 29 or the shaped socket section 67, the tubular redu- pin 70 through the reduced hole section 65, section 68 , around which a contact ring presses, and the contact socket 29 or the is, and the tubular sleeve section 38 have 20 pins 70 for removal can easily be pulled out through the openings 37 of a smaller diameter than that between and 37 &. Hole section 65 provided in this way with conical surfaces and with a reduced diameter in the plug body 21. The contact socket 29 or the contact pin 70 can be reduced in diameter. Together with the surface seal 71 and also the attachment of countersunk bores at both ends of the 25 itself, the deformable intermediate plate 22 forms a hole in the plug body that ends with a seal against harmful environmental influences, conical surface, so that the section between the such as moisture. The dielectric two countersunk bores formed by the two conical surface coating 56 prevent a short circuit through the bordered hole section 65. After inserting contamination or from conductive particles. Wezen in the plug body 21 can be achieved with the help of a 30 gene of the high resistance, which is ensured by the dielectric tool, which see a sleeve on the front end coating 56, and a leadless mechanical pencil increased reliability, and the possible resembles and whose sleeve-shaped end the tubular sections 67, 68 following on one another and is increased. As a result, the tension wedge 38 of the contact socket surrounds the open, slotted 35 and the insulation resistance is improved.
The end 66 of the retaining clip 46 is advanced and thereby it is understood that a filter plug-in part norder the retaining clip 46 in the space between the cones is not used together with another filter surface of the reduced-diameter hole plug part if the attenuation is achieved section 65 and the reduced diameter would result therefrom is not required. In this case, section 45 of the contact socket is pushed, 40 is normally used as a second plug part so that the contact socket can be inserted. Usual, filterless plug part used
After the tool has been removed, the flange 66 of the resilient retaining clip, which protrudes outwardly described above, springs up the grounding in a conventional plug-in 46 and surrounds the adjacent conical contact strip for frame construction, it is shown as in section 43 of the contact socket, so that a movement 45 considered lying within the scope of the invention that that of the contact socket is prevented in any direction. The arrangement according to the invention also between the In the same way, the retaining clip 96 locks the contact parts of a conventional plug coupling arranged in the plug body 57. In this state and the filter contacts are located in a housing, the reduced tubular section 61 can be accommodated, which Their use or part of the external occupancy of the filter condenser enables them to be removed when they are not required; sators, which are 55 with a dielectric coating.
