Definitions

  • the invention is based on a socket for an electronic device.
  • These sockets have long been used in electronic devices, especially computers. They are often referred to as D-Sub connectors. It can be both pin headers and socket headers, so that the term socket used here is intended to encompass both possibilities.
  • the sockets currently used contain in a mostly two-part metallic housing a component made of insulating material which contains the metallic parts in through openings. These are formed on the one side, the outer side as plug pins or also as socket pins and continue in one piece in connection elements which generally protrude from the insulating piece on the opposite side of the housing. With these outstanding connection elements, they are soldered into printed circuit boards or fastened using press-fit technology.
  • the metallic housing forms a certain shielding, electromagnetic interference can get into and out of the device on the lines themselves.
  • the invention has for its object to provide a socket of the type mentioned, which itself offers a possibility on the socket itself to act directly on the lines with the aid of electronic circuits.
  • One of the possibilities of action is to be a filter for filtering out disturbances.
  • the invention proposes a socket with the features mentioned in claim 1. Developments of the invention are the subject of dependent claims.
  • circuit board element With the help of the circuit board element, it is possible, by providing solder pads, soldering points or the like, to attach circuit elements directly to the socket itself, which enables a direct effect on the lines connected through the socket.
  • One of the possibilities is to provide a filter circuit, for which capacitors can be used, for example.
  • the possibility created by the invention to accommodate circuit elements on or in the plug itself can also be used for other purposes.
  • the circuit board element has a metallized area which is in electrical contact with the housing.
  • This can be, for example, a flat side or also an edge, wherein the metallized area on the flat side can extend as close as possible to the passage of the plug pins.
  • the metallization, which is in electrical contact with the housing, is used for shielding.
  • the circuit element is connected between the plug pin or the individual socket and a part electrically connected to the housing, in particular the metallized area of the circuit board element.
  • the circuit board element has a number of bores through which the pins are pressed, corresponding to the number of pins or individual sockets, through which the pins are pressed, the circuit element being connected to the plated-through hole.
  • the circuit element can be attached before the plug pins are inserted through the plated-through holes.
  • the pins or sockets can also have a press-in zone located outside the plug, so that they can also be pressed into the printed circuit board.
  • the circuit element can be attached, for example, by the circuit element being applied to solder pads of the circuit board element using SMD technology. This is a proven solution that can also be used with this circuit board element according to the invention.
  • circuit board element is to arrange it outside the metallic housing.
  • the printed circuit board element rests on the metal housing with a flat side metallized at least in its edge region.
  • the printed circuit board element may lie on the electronic device after the plug socket has been attached, with a metallization of the device itself lying on ground, for example on a printed circuit board of the device.
  • the housing has contact towers which can be pressed into bores in a circuit board of the electronic device, the circuit board element possibly being arranged between this circuit board and the housing.
  • the housing is pressed in with the aid of the contact towers, the printed circuit board element is then also pressed onto the metallic housing.
  • the at least one or the plurality of electronic circuit elements can be attached, for example, on a flat side of the circuit board element.
  • the circuit board element has at least one recess in which the electronic circuit element is accommodated. It can then be arranged so that it remains level so that a flat boundary surface remains.
  • a separate recess or depression can be provided for each circuit element, or else a single continuous recess or depression for a number of circuit elements.
  • a second possibility of attaching the circuit board element is to arrange it inside the housing. This has, inter alia, the advantage that no difference to the previous plug sockets can be seen from the outside, so that the plug socket can be fitted in the same manner and with the same dimensions as previously.
  • the circuit board element with its preferably metallized edge the housing is connected, in particular pressed against this. This can be achieved by appropriate dimensioning of the circuit board element or the housing.
  • the circuit board element is expanded from two disks with matching through holes and the electronic circuit element is arranged in the area of the separating surface between the two disk parts.
  • the pane parts to be connected to one another preferably have a metallization on their separating surfaces, which is interrupted only in the central region where the through holes and the circuit elements are arranged. In this way, a tight arrangement is also created in electromagnetic terms.
  • a cavity, a cutout or the like is formed in the region of the separating surface for accommodating the circuit element.
  • the cavity for the circuit element is formed in a third disk, which is interposed between the two other disks and enclosed by them.
  • Fig. 1 shows a socket 1, which is attached to the top of a circuit board shown only broken.
  • the socket 1 contains a metallic housing 3, which is usually made up of two parts. Each housing part has a flange. The two housing parts are connected to one another with their flanges, which lie in one plane, so that a common housing flange 4 is formed.
  • the housing 3 is open on its upper side in FIG. 1, ie facing away from the printed circuit board 2, so that there can be an intervention in the housing.
  • the housing On the opposite side, ie facing the printed circuit board 2, the housing also has an opening which is delimited by the slightly bent edge of the housing.
  • a flange 5 is fastened, for example riveted, to the flange 4 in the area of the two ends shown in FIG. 1, which has an internal bore with a thread in the area of its end facing away from the printed circuit board 2.
  • the spacer tower 5 contains a fastening pin 6 with a somewhat reduced diameter, which has a corrugation. With this fastening pin, both spacer towers are pressed through a first circuit board element 7 into holes in the circuit board 2.
  • projecting connection elements 8 are pressed into openings in the printed circuit board 2 on the side of the housing 3 facing the printed circuit board.
  • the connecting elements 8 are the one end of plug pins held in the housing 3 in an insulating body, which could also be designed as sockets on the upper side in FIG. 1.
  • Such plug pins or individual sockets are usually arranged in such a housing 9 or 25.
  • the circuit board element 7 arranged between the printed circuit board 2 of the electronic device and the housing 3 is pressed against the housing 3, so that it comes into a conductive connection with the housing 3.
  • This conductive connection could also take place via the spacer towers 5 or also via a connection surface of the printed circuit board 2.
  • FIG. 2 shows a top view of a flat side of the circuit board element 7 of FIG. 1.
  • the circuit board element 7 has an elongated rectangular shape, the length and width of which approximately corresponds to the housing 3 or the flange 4 thereof. In the area of its two ends, the circuit board element 7 contains a through hole 9 for the fastening pin 6 of the spacer towers 5.
  • the flat side of the circuit board element 7 has a metallization 10 extending over the entire circumference in the edge, which leaves a rectangular interior 11 free. In this interior 11, which is only shown on the right, the through openings for the connection elements 8 are arranged, which are provided with a plated-through hole and merge into lateral soldering tabs 13.
  • soldering tabs 13 are arranged in the surface of the flat side of the circuit board element 7 and extend in the direction of the metallized edge of the circuit board element 7.
  • An electronic switching element can be placed on the space between a soldering tab 13 and the metallized edge 10 and fastened by soldering.
  • an SMD component using SMD technology can be attached at this point. It therefore creates a connection between the connection element 8 pressed into the through hole 12 and thus the associated plug pin and the edge metallization 10 of the circuit board element.
  • the circuit board element 7 is in conductive connection with its metallization via the pins 6 to ground.
  • an electronic component for example a capacitor
  • a single line connected by means of the plug socket. This is preferably done for all lines used, so that a filter device is created which covers all lines.
  • FIGS. 3 to 7 uses a connector in which a modified structure is located inside the housing he follows. This is initially shown schematically in FIG. 3, where, for example, an upper part 14 of a metallic housing 3 is shown unfolded. In the case of which only that Upper part 14 is shown, a circuit board element 17 is arranged, which is composed of two disc parts 17a, 17b. Both disc parts have the same outline shape and have matching through holes 18 for the passage of either the spacer towers 5 or of fastening screws or rivets.
  • the mutually facing flat sides of the two pane parts 17a, 17b have a metallization 19, which is arranged similarly to the metallization 10 in the embodiment according to FIG. 2.
  • a metallization 19 which is arranged similarly to the metallization 10 in the embodiment according to FIG. 2.
  • two fields 11 in the middle remain free of metallization.
  • the through openings for the plug pins or socket pins extend through these fields. These openings are not shown in the simplified illustration in FIG. 3.
  • FIG. 4 now shows a top view of the lower pane part 17b in FIG. 3. This time, the area 11 free from the metallization 19 is also shown.
  • soldering lug 24 On the opposite side of each hole 21, starting from the edge, a similar soldering lug 24 is provided, which has the same shape as the first mentioned soldering lug 23. Between the two soldering lugs 23, 24, each associated with a hole 21, a surface free of metallization is therefore provided which can be bridged using an electronic circuit element. For each hole 21, a possibility is thus created to create a connection to the metallization 19 of the disk part 17 by bridging two adjacent solder lugs 23, 24.
  • FIG. 5 shows a side view of the lower disk 17b of FIG. 5, sectioned in the middle part.
  • the holes 21 are stepped bores which, starting from the top 25 facing the respective other disk part 17a, initially have a larger diameter than on the opposite side 26.
  • FIG. 6 shows a bottom view of the upper pane part 17a in FIG. 3.
  • passage openings 27 are arranged for the contact pins, which are aligned with the holes 21 of the lower disk part 17b. Contacting need not be provided here, since contact is made at the holes 21 of the other disk part 17b.
  • FIG. 7 shows the view of the underside 26 of the lower disk part 17b of FIG. 4.
  • the holes 21 with their plated-through holes 22 open into a metallization 28 of the flat side of the disk part 17b.
  • the metallization is brought up to close to the plated-through holes 22 of the holes 21.
  • the socket of the embodiment according to FIGS. 3 to 7 is manufactured in such a way that the printed circuit board parts 17a and 17b are first manufactured, drilled and provided with the metallization. 4, the electronic components, for example the capacitors, are then applied and soldered in an SMD construction.
  • the two pane parts 17a, 17b are then placed on top of one another and connected to one another, either by soldering or by gluing. This creates a component that is constructed similarly to the insulating body in the conventional sockets.
  • the metal parts which on the one hand form the connection elements 8 and on the other hand the individual plugs or single sockets, can now be pressed into this component by inserting and pressing them into the holes 27 and 21. The arrangement can then be inserted into the housing and closed.
  • 8 to 10 show a further embodiment which is similar to the embodiment of Figs. 3 to 7. Again, it is a printed circuit board element that is attached within the housing, and this time consists of three disk parts that are placed on top of one another with their metallized separating surfaces and connected to one another. 8, 9 and 10 only show the central component which has a through hole for each contact pin and a second through hole directly next to this through hole Bore for an electronic circuit element, so for example the capacitor mentioned.
  • the capacitors are soldered with the aid of solder paste in the parallel bores, wherein they are connected to the plated-through holes on the first flat side of the disk element shown in FIG. 8, while they are soldered to the metallization on the opposite flat side shown in FIG. 10 will.
  • the pins 30 have a press-in zone 31 for pressing into a printed circuit board arranged inside the housing and a second press-in zone 32 outside the housing. With the help of this press-in zone 32, the connector pins are pressed into the printed circuit board to which the connector strip is fastened using press-fit technology.
  • the pins contain a lateral slot 33 which extends in the longitudinal direction of the pins and which can be milled, for example. This creates a somewhat elastic zone that can be used for pressing.
  • the pins can be designed both as pins and as bushings.
