Definitions

  • the invention relates to an electrical connector which has at least one electrically conductive contact element.
  • Connectors are used to connect usually portable electrical consumers.
  • the plug connector with its free end area formed on its connection side is connected to an electrical line connection.
  • the contact side, its other free end area which can be designed as a plug or socket, is plugged into the electrical consumer, for example via a connector designed as a counterpart.
  • Electromagnetic interference is a serious problem with the electrical transmission paths produced by plugging the electrical connectors together. This interference can lead to considerable difficulties, especially with the ever faster digital technology.
  • filters are installed in the transmission paths in order to attenuate these undesirable disturbances.
  • the prerequisite for this is that the filters differ in level and / or frequency from the useful signal to be transmitted. With multipole signal lines are necessary Separate filters are used for each transmission path in order to reduce the conducted electromagnetic interference to a total of harmless values.
  • filters can be provided in the input circuits of the devices or upstream of the device input. In both cases, there are connectors that are equipped with the appropriate filter elements. These so-called filter connectors can be equipped with a pin or socket strip.
  • Connectors with individual contact elements are known in which a filter for electromagnetic interference is firmly integrated in the respective individual contact element.
  • the contact elements form a complete component with the filter. A subsequent completion of individual contact elements with filters is practically impossible.
  • connectors with planar filters are known.
  • the required filters are applied to a ceramic carrier designed in thick film technology and soldered to the connector contacts and the housing for the ground connection. Soldered connections not only involve increased manufacturing costs, but also represent an undesirable thermal load for the ceramic materials.
  • the filter elements are designed as cylindrical bodies.
  • a cylindrical body is pushed over the connection side of the contact element.
  • the electrically conductive inner lining of the cylindrical body acting as a capacitor is soldered to the contact element and thus connected in an electrically conductive manner.
  • the electrically conductive outer coating of the capacitor is also soldered to an earth plate. Due to the solderingly firm connection between the capacitor designed as a sleeve and the contact element inserted through the sleeve on the one hand and between the sleeve and the grounding plate on the other hand, a rigid unit formed from the contact element and grounding plate or plug housing is provided.
  • the contacts thus lack any possibility of diametric play in order to adapt to the contacts of the mating connector during the plugging process. Radial and axial forces acting on the contact element are consequently transmitted to the capacitor and must be absorbed by the latter in terms of strength. Since the capacitors break very easily when subjected to mechanical loads, rejects and failures are not uncommon. In addition, the soldering processes required to manufacture these connectors prove to be not without problems since the ceramic materials used in the capacitors are very sensitive to rapid temperature changes. Soldering cracks can therefore often not be avoided in the ceramic bodies.
  • the filter is installed solderless.
  • a sleeve-like, longitudinally slotted spring element that is bulged in its central region is supported with its two end regions in each case in a recess formed in cross-section in the contact element, while its central, bulged region presses against the inside of the capacitor. Due to the location of its two end regions on the contact element, the end regions cannot migrate in the longitudinal direction of the contact element if the contact pressure between the contact element and the capacitor should become too great due to manufacturing tolerances, for example. This could have the consequence that the very thin and not very strongly adhering electrically conductive inner coating of the capacitor could also be damaged, for example, when it is pushed onto the spring element.
  • each contact element must be equipped with a capacitor, since the contact element in question cannot find any lateral support in the region of the housing opening without a capacitor.
  • the invention has for its object to provide an improved electrical connector.
  • This invention is given by the features of claim 1. Starting from that known from the prior art The invention is characterized on the one hand by the fact that a connector with capacitors pushed onto the contact elements as a sleeve is characterized in that an elastically deformable, electrically conductive and body-like element body is present between the contact element and the inner surface of the capacitor, the element body having two end regions of different cross-section .
  • the cross section of the contact element is constantly large in this area, so that the element body acts in the manner of a contact spring that escapes in the longitudinal direction of the contact element.
  • the capacitor is also held in the longitudinal direction within the connector housing between a thickening formed in the transition region between the connection side and the contact side of the contact element and a projection of the insulating body enveloping the capacitor.
  • the perforated insulating plate or insulating film arranged between the grounding plate and the end faces of the capacitors effectively effectively prevents the risk of a short circuit.
  • the insulating plate ensures that the grounding plate connected to the outer surface of the capacitor cannot come into electrical contact with the thickening and thus ultimately with the contact element.
  • a soldered connection is not required between the contact element and the capacitor designed as a sleeve. This reduces the assembly time.
  • the production scrap is also significantly reduced compared to conventional connectors.
  • the axial and radial movements of its contact elements that occur during handling of the connector can be absorbed by the longitudinally and transversely movable (resiliently deformable) contacts without the filter elements being exposed to a destructive mechanical load.
  • a further improvement is possible in the inventive connector in that the respective capacitor is not soldered to the grounding plate, but can also be held on the grounding plate by means of collar-like projections. These collar-like projections can also be designed to be resilient. As a result, the capacitors are held floating in the connector.
  • the electrically conductive element body can be produced by rolling a band provided with slot-like punchings in its one edge region.
  • the band ends do not need to be closed to form a ring.
  • the connector 10 shown in detail in FIG. 1 has a housing 12 on the contact side and a housing 14 on the connection side.
  • the contact side represents the part of the connector 10 which is mated with a mating connector (connector 10.2, FIG. 2) can be electrically connected by plugging together.
  • the connection side of the connector is used to connect this connector to existing line connections, such as line cables.
  • the housings 12, 14 have outwardly projecting collars 16, 18 which are firmly connected to one another at the connection point 20.
  • both collars have a through bore 22.
  • a plurality of contact elements 30 are present in the interior of the housings 12, 14, of which three contact elements are shown in the present exemplary illustration.
  • Each of the contact elements 30 has a rod-shaped contact pin 32 which protrudes from a circumferential thickening 34. On the other side of the thickening 34 there is also a rod-shaped connecting pin 36. Terminal pin 36 and contact pin 32 have the same longitudinal axis 38.
  • an insulating body 40 in the housing 12 which corresponds to the number of contact pins 32 Breakthroughs is provided.
  • This insulating body 40 has an outwardly projecting shoulder 42 with which it is supported from the inside on the collar 16 of the housing 12. As a result, the insulating body 40 cannot fall out of the housing 12 to the right in the drawing. Because the insulating body 40 also bears against the bulge 34 with a recess 44, it cannot move within the housings 12, 14 to the left in the drawing.
  • each connection pin 36 is surrounded by a capacitor 50 designed as a sleeve.
  • a spring element 52 in the form of a sleeve is present in the space between the connecting pin 36 and the capacitor 50. With its edge region 54 on the left in the drawing, which is smaller in cross section, this spring element 52 presses on the connecting pin 36. Since the spring element 52 is electrically conductive, there is a line connection between the connecting pin 36 and the electrically conductive inner surface 58 of the capacitor 50.
  • a grounding plate 64 with a bend 66 presses against the likewise electrically conductive outer surface 62 of the capacitor 50.
  • the grounding plate 64 has a correspondingly large cutout in the region of the capacitor.
  • the bend 66 is present all around, so that the outer surface 62 rests with an annular surface on the bend 66 and thus on the grounding plate 64.
  • the bend 66 is shown in the drawing in section as U 66.1 open to the left.
  • the grounding plate 64 has an S-shaped bend 68 in order to fit on the one hand into the area between the two collars 16, 18 of the two housings 12, 14 and on the other hand to the end area 70 of the To pass capacitor 50, which is adjacent to the thickening 34.
  • the grounding plate 64 is firmly connected to the housings 12, 14 in the region of their connection point 20, so that there is an electrically conductive connection of the outer surfaces 62 of the capacitors 50 to the housings 12, 14.
  • an insulating film 72 is additionally arranged between the end regions 70 of the capacitors 50 and the thickenings 34 of the contact elements 30.
  • This insulating film 72 is intended to prevent electrical contact between the outer surface 62 of each capacitor 50 and thus between the grounding plate 64 and the thickenings 34 and thus ultimately with the corresponding contact elements 30.
  • each capacitor 50 With its other end region 74 directed away from the thickening 34, each capacitor 50 abuts the projection 82 of an insulating body 84 with play. As a result, the capacitors 50 are held with play in the direction parallel to the longitudinal axis 38.
  • the insulating body 84 is in turn prevented from falling out of the housing 14 by an indentation 86 at the end of the housing 14.
  • Embossments 90 can be present in the housing 12, as is known per se in the case of plug connectors 10, in order to establish good contact between the housing 12 and the housing of a mating connector.
  • the constructive integration of the capacitors 50 within a connector 10 is only shown by way of example by the above illustration.
  • the arrangement of such capacitors 50 and their attachment to contact elements 30 is not limited to D-subminiature plug connectors 10, but can also be provided with other contact elements 30.
  • the connecting pins 36 it is also not necessary for the connecting pins 36 to be present as rods or as wires. So the pins 36 can also in Be formed in the form of bushings.
  • the number of contact elements 30 within a connector 10 is arbitrary and depends only on the type and purpose of the respective connector.
  • connection side corresponds to the connection side of the contact element 10 according to FIG. 1.
  • contact sockets 32.2 on its contact side, which are surrounded by insulating bodies 40.2. These contact sockets are connected in one piece via the thickening 34 to the connecting pins 36, as is also the case with the contact pins 32 in FIG. 1.
  • filter elements therefore has no constructive influence as to whether there are contact pins or contact sockets on the contact side of a connector, since the filter elements are arranged on its connection side.
  • the housing 12 can be seen from the plug connector 10, which, when the "plug” (FIG. 1) and “socket” (FIG. 2) are connected, envelops the housing 12.2 of the plug connector 10.2 on the outside.
  • the bulges 94 present in the wall of the housing 12.2 together with the bulges 90 of the housing 12 bring about a good mutual contact of the housings 12, 12.2.
  • each capacitor is arranged inside the connector without a solder connection and is only held frictionally on the components surrounding it (grounding plate, insulating body) and on the respective contact element, the respective contact element can be installed in an unchanged design even without a filter.
  • the contact elements that transmit a signal voltage can each be arranged with a filter, while the contact elements that transmit a supply voltage can be arranged within the same housing without a filter. Any special structural or other measures need not be taken into account.
  • FIG 3 shows an exploded view of how a contact element 30 in the form of a contact pin 32 is provided with a capacitor and is used in two housing halves.
  • Insulating body 40 is inserted into housing 12 on the contact side of a connector. Subsequently, the contact element 30 with its contact pin 32 is inserted into the insulating body 40. In a comparable manner, several contact elements are inserted into the housing 12 accordingly.
  • the insulating film 72 is pushed onto the connecting pin 36 of the contact pin 32.
  • the component consisting of the capacitor with a seated spring element 52 is then pushed onto the connecting pin 36.
  • This component can be pre-assembled in a separate operation. This has the great advantage that after the spring element has been inserted into the capacitor, the functionality of the capacitor and thus the inviolability of its inner electrically conductive inner coating can be determined. When the spring element is inserted into the capacitor, the inner coating can be mechanically damaged.
  • connection pins 36 can be present in an unchanged design, namely with or without a capacitor 50 within the housings 12, 14.
  • the representation acc. Fig. 4 differs from the representation acc. Fig. 3 in that 32 contact sockets 32.2 are provided instead of the contact pin. Accordingly, the contact side and thus the housing 12.2 and the insulating body 40.2 are different from the corresponding design for the contact pins 32.
  • the design of the connecting pin 36 and the components seated on it, such as the insulating film 72, the capacitor 50 with a seated spring element 52, the grounding plate 64 and the housing 14 with insulating body 84 correspond to the components in the illustration according to. Fig. 3. Also in this connector designed as a "socket" can with its individual pins 36, as well as in the connector designed as a "plug" acc. Fig.
  • capacitors 50 are provided or omitted. It is important that the functionality of the capacitor 50 and its inner electrically conductive inner coating, which could all too easily be mechanically damaged when the spring element 52 is inserted, at a point in time at which the spring element 52 is already inserted into the capacitor 50, by an electrical measurement can be easily determined. The functionality can therefore not be determined only when the capacitor is available mounted on the pin 36.
