    Multipole Connector The invention relates to a multipole connector that receives a mating connector, comprising a housing in which an insulating body having a number of contact inserts, each with a jack or pin, that corresponds to the number of lines led through for connecting the lines. Connectors of this type are, for example, known as D-type subplugs or D-type subjacks. They are used as output and input connectors in housing walls of electronic apparatus, in particular in calculators or the like, so that a connecting line can be connected to it via a mating connector. The disadvantage thereby is that connectors of this type cannot be made watertight to meet higher demands. As a result, there is the danger that water can penetrate into the housing and cause damage. Therefore, the object of the invention is to improve connectors of this type in such a way that they prevent the ingress of water while maintaining its miniaturized connector design, so that the connector can also be attached to the housing in a watertight manner to meet higher demands. This object is solved by the features of the characterizing part of the main claim; the subclaims describe advantageous improvements and preferred embodiments. _ 2 _ The connector known per se is inserted into a frame which, depending on the type of assembly, is provided with a seal on its front or on its rear. To this end, the frame is provided with a circumferential groove on at least one side, preferably on both sides, said groove receiving the seal. Depending on the application and type of assembly, the seal is placed against a connector board of a housing, against a mating plug or a cap and in this way ensures the necessary watertightness. It is thereby understood that either a flat plate or a mating groove into which the seal penetrates is provided as a bearing surface for the seal. Advantageously, a sealing ring, i.e. an O-ring, or a form seal is used which is inserted into the circumferential groove. The form sealing is advantageously made of a thermoplastic elastomer by an injection molding process, having a basic form corresponding to the groove and a corresponding cross section. Advantageously, one embodiment of the circumferential frame comprising the insulating inlay provided with the contact inserts, optionally with the mating connections, is covered with a hardening plastic compound. In one embodiment, to cover it, the rear of the frame with the insulating inlay having the contact inserts is cast with the plastic compound. In another embodiment, this rear side is injection molded with a thermoplastic material. In this way, the insulating inlay itself can be connected with the frame in a watertight manner. Advantageoulsy, a thermoplastic material is provided as the plastic compound for the injection molding or casting. In one embodiment, plastics of this type can be halogen-free and selected from the group of polycondensates; advantageously, polyamide, polyester, polyvinyl, polyolefin, polyurethane plastics or the like. Alternatively, polymers or polyadducts can also be used; in this case, polystyrols, polyacetates, polyvinyls, polyacrylates or the like or linear polyurethanes are advantageously provided. Alternatively, halogen-containing thermoplastic materials can be used, especially with high demands for low flammability or fire-retardant properties. These are advantageously selected from polymerisates or polyadducts, i.e. chlorinated polyester, polyvinyl or polyvinylidene chloride, chlorine fluoride or fluoropolymers, or the like. The plastic substance with which the connector is cast or injection molded is thereby selected in such a way that it is sufficiently heat-resistant, so that the soldering of the connections to produce the connections between the connector contact inserts and the associated conductors or conductor paths is made possible. Apolyurethane sealing compound has shown to be advantageous for this. The mating plug to be connected is designed in the same way, so that the interface can be completely sealed. For this purpose, it has a protective covering which is provided with a seal inserted into a circumferential groove. The screws used for the screwing are extended and guided through the edged beading of the protective covering provided with a circumferential seal in such a way that they align with the screw jacks of the connector and in this way enable the connector and mating plug to be screwed together. It is thereby possible to attach the mating connector to a fixed connector. If the frame with inserted connector is inserted into a further protective covering, a cable/cable connection can also be made. The frame is thereby inserted so as to be sealed, for example, interacting with seals in the protective covering or by means of sealing compounds. To seal against the mating connector, as well as when using on a connecting plate, a seal is provided. It adjoins the groove provided in the mating connector in a sealing manner and is pressed into it in part so as to seal it, which in this manner produces the desired or required necessary watertightness. To close an open interface formed by the connector, a cap is advantageously provided. It corresponds, to the extent that the parts required to cover the interface are involved, to the mating connector in its geometry. In this way, it is possible to cover the open connector of an interface so as to seal it. In order to also obtain an electric shield in addition to the mechanical protection, the protective cap advantageously consists of a metal. Alternatively, the cap can also be designed as a plastic cap, in this case, metallization is provided. The metal cap or the metallized cap is thereby configured in such a way that the metal body or the metallization is galvanically connected with the metal body of the connector to be covered.To fasten this protective cap, similar to known screw fastening of a mating connector, it is provided with screw fastenings which correspond to the screw jacks of the connector. If the connector to be covered has spring clips, then corresponding catches with which the spring clips interact can also be provided on the cap in a similar manner. It is thus understood that other fasteners can also be provided. To also seal against water spray, the edge of the protective cap is provided with a circumferential groove. If a seal is inserted into this groove, a sealing of the connector closed with this cap can be obtained, which can also meet higher demands by selecting the appropriate seal and tightening. These seals can thus be made of the previously mentioned materials, the requirements to be met by the connector determining the selection of the material. The essence of the invention will be described in greater detail by way of example with reference to the Figs. 1 to 8, showing: Fig. 1: connector in housing wall (top view, section); Fig. 2: connector (longitudinal view, partial section); Fig. 3: connector (front view, partial section); Fig. 4: connection (bottom view); Fig. 5: connector with attached mating connector (front view, partial section); Fig. 6: detail of connector of Fig. 5 - screw fastening (partial section); Fig. 7: connector with protective cap (longitudinal view, partial section); Fig. 8: connector with protective cap (front view, partial section). The connector 2 built into a connector board 1 and fastened in it in a conventional manner is provided with a housing 3 which has at least one collar 4. This collar 4 receives the mating connector (not shown in greater detail) in the connector which is held by means of screws 27 (Fig. 6) which engage in the screw jacks 15 which ensure a continuous contact to the ground. The connector 2 is provided with an insulating body 5 in which the contact inserts 6 corresponding to the connector design of connector 2 and its mating connector are situated, so that the plug pins and jacks of the connector and mating piece lie complementary to one another and in this way also enable the continuous contact of the lines to be connected.In the illustrated figures, these contact inserts 6 have jacks 7 which receive the pins of the connector to be connected (not shown in greater detail) , it being understood that the pins and jacks can also be interchanged. The contact inserts (6), provided with jacks 7 here, continue on the back and are in the form of soldered projections 8 to which either connection wires for connecting with the associated lines or the associated lines (both not shown in greater detail) are directly connected. A filter 9 is inserted here between at least one contact insert 6 and the ground. The insulating body 5 is surrounded by a frame 10 which is made of an insulating plastic and which accommodates the insulating body 5 almost in a form-locking manner. This frame l0 has at least one peripheral projection 1l on one of its sides which has a groove 11.1 in which a seal 12 is situated. This circumferential seal 12 is advantageously formed by a loop, an O-seal or a form seal having a shape and cross section that corresponds to the groove or the like. In this way, the frame 10 is sealed at least against spray water, however, also insulated vis-a-vis the connector board 1 generally at ground potential. By selecting a conductive plastic, a ground connection can also be created here, and also the corresponding contactings. The insulating body 5 and the frame 10 of the connector (in Fig. 4, since not visible when seen from the covered rear and designated with (2)) are covered with sealing compound 13, e.g. by casting or spraying. It is therefore possible that the frame and cover can be formed by injecting molding, and the insulating body 5 in one step, from one plastic or in successive steps from two plastics by means of a known plastic injection molding method. The mating connector 20 is provided with pins which engage in the jacks 7 of the connector. Its structure essentially corresponds to that of the connector 2. A housing 21 receives the contact insert 23 which is provided with plug pins 23.1 which interact with the jacks 7. The housing has a circumferential groove 22 into which a seal 22.1 is inserted which (in the embodiment shown in Figs. 5, 6) interacts with the connector board 1 and is pressed against it. A protective covering 25 surrounds the mating connector 20 whose outgoing lines 29 are led out as a connection for a cable. As previously described, this protective covering is made of plastic and has a circumferential projection 26 directed to the open connector side, a circumferential groove also being made again in said projection. A seal insert 26.1 is inserted into this groove which adjoins the connector board 1 in which the connector is inserted when the connector 2 and mating connector 20 are coupled. It is thereby understood that, with a cable/cable connection, there is a corresponding installation on the frame 10 of the connector 2 inserted into a protective covering (not shown in greater detail). The protective covering 25 is also a plastic protective covering. As described in greater detail above, in one embodiment, halogen-free plastics selected from the group of polycondensates or polymers of polyadducts are used as plastics; alternatively, in another embodiment, halogen-containing thermoplastic materials, i.e. halogenated polymerisates or polyadducts, can be used, especially with high demands for low-inflammability or fire-retarding properties. To securely fasten the mating connector 20 to the connector 2, a screw connection is provided in the selected representation. For this purpose, extended fastening screws 27 are led through the projection 26 in such a way that they can be screwed into the screw jacks 15 so as to align with them. For the sealing, a gasket 27.1 is inserted below the head of the fastening screw 27, said gasket adjoining the edge of the screw opening in the protective covering 25. Furthermore, the screw 27 has an annular tee-slot 28 in the area of the body of the protective covering 25, said annular tee-slot receiving a radial seal 28.1 as a circumferential seal. In this way, the screw lead-through is also sealed against the ingress of water . To be able to seal a fixed interface having an open connector 2 or a cable interface with an open mating connector 20, a protective cap 30 is provided which is fastened with the same fastening means to the connector 2 or to the mating connector 20. In Figs. 7 and 8, these fastening means are shown as fastening screws 33 which align with the screw jacks 15 of the connector 2 and engage in them, however, this does not exclude other fastening means. In the representation of Figs. 6 and 7, the protective cap 20 has a cap housing 31 in which an elastic sealing insert 34 is inserted. It will be understood that the cap housing 30 with sealing insert 34 can also be made as one piece from a suitable plastic. In both cases, the sealing insert 34 can be made in such a way that, with its raised edge 35, it adjoins the collar 4 of the connector 2 so as to seal it and is pressed against it after the fastening means have been screwed on.
