Abstract

The invention relates to a connector with a plurality of plug contact pins, a housing in which the plug contact pins are arranged, and a circuit board, which is arranged in the housing and is electrically connected to at least one of the plug contact pins. The invention is characterized in that the board is fixed in the housing in such a way that it is mechanically decoupled from the plug contact pins and / or the housing so that relative movements between the plug contact pins and the housing do not cause any tension in the board.

Description

  • The The present invention relates to a connector with integrated Circuit board.
  • It There are D-sub filter filter connectors that have a housing have, in which a plurality of plug contact pins are arranged. In the housing is a circuit board. The board is provided with holes through which the plug pins extend. The plug pins are soldered to the board. On The board is a capacitor for each plug contact pin provided, which led by plug pins to filter electrical signals. The board is with the case mechanically and electrically connected by means of a solder joint. Since the housing is connected to ground, this forms solder joint the ground connection for the board.
  • such Filter plugs have proven themselves in practice, as with they can be filtered by interfering signals. The Integration of a board in such a miniaturized connector However, it is problematic because such a board is sensitive to mechanical loads. For plug-in operations is a a significant proportion of the insertion forces absorbed by the board. These insertion forces lead to damage the board and damage the solder joints between the plug contact pins and the board or between the Board and the housing. The life of these connectors is therefore limited.
  • Even though integrating a board into a miniaturized connector is very advantageous because a board basically any Circuit arrangements allowed, the variety of circuits limited only by the limited area of the board is, such miniaturized filter plug have been almost designed exclusively without blanks. There are a number of different solutions.
  • So revealed the EP 0 137 116 B1 a connector with chambers in which monolithic capacitors are arranged. The capacitors are pressed by means of a spring element against the plug contact pins so that they are electrically connected thereto. These connectors are mechanically simple and reliable. They have a long life. However, the electrical contacts between the capacitors and the plug contact pins can be released in vibration, whereby the filter characteristic is impaired. With these connectors is disadvantageous compared to connectors with integrated circuit board, that only capacitors can be brought into electrical contact with the plug contact pins and a further electrical connection is not possible.
  • From the EP 0 712 141 B1 goes out a connector having a plurality of parallel arranged in a grid plug contact pins. The plug contact pins are surrounded by a strip body. The strip body is designed as a filter element. It consists of a mixture of insulating material and ferrite material. This strip body forms an electrical inductance for filtering unwanted high frequency signals. This generates EMC protection. There are also separately formed tubular ferrite body, each enclose a plug contact pin to form an inductance on the plug contact pins.
  • From the EP 1 315 253 A1 goes out a capacitor body for a connector. The condenser body consists of a monolithic ceramic body with tubular passageways. This ceramic body is coated with metal so that it represents with each passageway a capacitor to each arranged in the passageways plug contact pins.
  • These attached filter elements (ferrite body, metallic coated ceramic body) have considerable tolerances in your electrical properties (inductance, capacity). Although they are mechanically stable in the long term, they can often do not meet the required electrical properties.
  • It there is a considerable need for a miniaturized connector, with electronic components such as capacitors and / or inductors is provided, which have only small tolerances, and the connector should also be the typical mechanical complaints by the plug operations and preferably also stronger mechanical complaints due to vibration can withstand.
  • Of the Invention is therefore the object of a connector to create, which has a long life and also an electric Interconnection allows the precise electrical properties having.
  • The The object is achieved by a connector having the features of the claim 1 solved. Advantageous embodiments are in the subclaims specified.
  • The connector according to the invention comprises a plurality of plug contact pins, a housing in which the plug contact pins are arranged, and a circuit board, which is arranged in the housing and is electrically connected to at least one of the plug contact pins. This connector is there by that the circuit board is mounted in the housing so that it is mechanically decoupled to the plug contact pins and / or the housing, so that relative movements between the plug contact pins and the housing cause no tension on the board.
  • By the mechanical decoupling of the board with respect to the plug contact pins and / or the housing are the plug-in operations applied insertion forces are not introduced into the board, so that the risk of damage to the board in comparison to conventional connectors with integrated circuit board is significantly reduced. This extends the Lifetime of the connector over conventional Connectors considerably.
  • By the provision of a board in the connector, it is possible the plug pins with any electrical circuits too connect. The variety of circuits becomes solely due to the limited area the board is limited. Coils can be arranged on the board whose inductance is much more precise as the inductance of plugged on the plug pins Ferrite is.
  • The mechanical decoupling of the board with respect to the plug contact pins and / or the housing is either by an elastic electrical connection between the board and the plug contact pins and / or the housing. This is appropriate if the board with both the plug pins and with the housing is electrically connected. In one embodiment, in the only one electrical connection between the plug contact pins and the board but not between the board and the housing should consist, the board is preferably arranged with play in the housing, leaving the board free with respect to the housing is mobile. In special applications, the mass is not over the housing but via a plug contact pin directed.
  • at a further preferred embodiment of the invention Connector are the plug pins with the board respectively mechanically and electrically connected by means of pressfit connection. This press fit connection does not represent a mechanical decoupling in this embodiment between the board and is to provide the housing. The massive used here Pressfit connection forms a very durable mechanical and electrical connection between the plug pins and the Circuit board. On the other hand, a flexible pressfit connection offers a minor one Game, so that it also contributes something to the mechanical decoupling.
  • at a further advantageous embodiment of the present invention Invention are the plug contact each of a pair of pins formed, wherein the pairs of sub-pins at a distance from each other are arranged. The board is located between the Part pins and it is an electrical connection between the Board and the sub-pins formed. This electrical connection is preferably by an elastic element, both at the Board and can be attached to the sub-pins, trained. This elastic element is for example an electrically conductive Spring body.
  • The Provision of such broken plug pins allowed it is to conduct the signal flow through the circuit, d. H., that electronic components arranged in series with the plug contact pin are. With continuous plug contact pins can electronic Components only connected in parallel to the plug contact pins become.
  • The Plug contact pins are in the housing by means of insulating mechanically fixed. These insulators are usually injection molded plastic parts. These injection molded parts have mechanical tolerances that are usually larger as the mechanical tolerances of the housing formed of metal are. This can cause a game between the insulators and the housing and thus between the plug contact pins and the housing is not always completely avoided become. By the inventive mechanical Decoupling of the relative movements between the plug contact pins and the case causes this game no problems. With two adjacently arranged insulating bodies, respectively shoulders formed on the plug pins between them clamp, serve for the axial fixation of the plug contact pins. By at least two spaced apart insulating body the plug-in pins are fixed tilt-free in the connector.

  • 14a - 14d each a filter circuit for a connector.
  • In the 1 to 5 a first embodiment of a miniaturized connector according to the invention is shown.
  • The connector 1 includes a housing 2 , the two housing halves 2.1 and 2.2 , a set of plug pins 3 , three insulators 4.1 . 4.2 . 3.4 and a board 5 having. In the present embodiment, the plug contact pins 3 at one end with a pin 6 and at the other end with a solder cup 7 educated ( 5 ). The pins 6 the plug contact pins 3 are in an opening of the housing 2 on a mating side 8th arranged. The solder cups 7 are at a back 9 of the connector 1 arranged and stand here in front of a piece.
  • The present embodiment is a sub-D connector. However, the invention is not limited to this construction. The housing 2 is an electrically conductive metal housing and can produce an electrical ground connection when plugged into a mating connector. At the mating side 8th shows the case 2 one the pins 6 enclosing socket 10 on, on the inside of Kontaktnoppen or Dimple 11 are formed to make a positive engagement with a corresponding mating connector.
  • The at the plug side 8th arranged insulating body 4.1 is referred to below as Frontteilisolierkörper. This front part insulating body 4.1 is a substantially planar plastic tile whose outlines slightly larger than the opening of the plug-side housing part 2.1 are. The front part insulating body 4.1 has on its side facing the mating side laterally two projecting webs 12 on, whose outside to the shape of the inner surface of the opening of the plug-side housing part 2.1 is adapted, so that the Frontteilisolierkörper hereby in the plane transverse to the direction of insertion 13 is positioned.
  • In the front part insulation body 4.1 are through holes in a standard grid 14 for receiving one of the plug contact pins 3 educated. The through holes 14 are opposite to the plug-in direction 13 stepped widened so that they are on the back of Fronteilisolierkörper 4.1 a recess 15 for the positive reception of one shoulder each 16 of the respective plug contact pin 3 form.
  • The plug contact pins have a plug-in section, which acts as a pin 6 ( 5 and 6 ) or as a socket 17 ( 6 ) is formed, then at the plug-in portion of the shoulder 16 , a cylindrical pin section 18 with a smaller diameter than the shoulder 16 , a pressfit section 19 and a soldering element 20 on. The shoulder 16 is one on the plug pin 3 circumferential projection with two flattened surfaces, which are formed opposite and parallel to each other. The recess 15 in the front part insulating body 4.1 has an exactly complementary shape to the shoulder 16 on, so here's the shoulder 16 and thus the plug contact pin 3 is received against rotation. The pressfit section 19 can be used as a square ( 5 ) or knurled ( 6 ) be formed. The maximum diameter of the pressfit section 19 is not larger than the diameter of the pin sections 18 , The soldering element 20 can as a solder cup 7 or be formed as a solder pin.
  • At the back of the front part insulation body 4.1 is the insulating body 4.2 arranged in the following as the first Rückteilisolierkörper 4.2 referred to as. This first Rückrückisolierkörper 4.2 again points in the grid of the plug pins 3 arranged through holes 22 on. The diameter of the through holes 22 corresponds to the diameter of the pin sections 18 the plug contact pins 3 so the plug pins 3 with her pen sections 18 in the holes 22 to store. Shoulders 16 the plug contact pins 3 lie opposite the direction of insertion 13 at the first back insulation 4.2 on, so that the plug pins 3 are set in the axial direction, as they are in the insertion direction 13 with her shoulders 16 at the front part isolating body 4.1 strike and in the direction opposite to the direction of insertion 13 with her shoulders 16 at the first back insulation 4.2 attacks.
  • The first back insulation 4.2 has two projections on its front 23 in the corresponding recesses on the back of the front part Isolierkörpers 4.1 intervention.
  • At the back of the first Rückrückisolierkörpers 4.2 At the corners protrusions are provided as spacers 24 serve. From these spacers 24 becomes the further insulator 3.4 hereinafter referred to as a second back insulation member spaced from the central portion of the first back insulation member 4.2 held. In the intermediate region formed thereby between the first Rückrückisolierkörper 4.2 and the second backseal insulating body 3.4 is the circuit board 5 , The board 5 is made of a printed circuit board and arranged on the circuit boards electrical components 26 educated. The printed circuit board is again in the grid of the plug contact pins 3 arranged through holes 25 educated. The through holes are coated on their inner surface with copper and form so-called vias. In the circuit board tracks are formed, which the vias with the electrical components 26 connect. These electrical components 26 are mainly capacitors and coils. They are designed as SMD components and are typically soldered and / or glued to the circuit board of the board. The printed circuit board is typically a multilayer plastic printed circuit board. However, it can also be made of ceramic. The electrical components 26 can be located both on the front and on the back of the board. In the present embodiment, the board 5 only on the side facing the plug side electrical components 26 , namely capacitors on. Each plug contact pin 3 in each case a capacitor is assigned.
  • The contour of the board runs so that it is between the spacers 24 the first Rückrückisolierkörpers 4.2 fits. The surface of the first Rückrückisolierkörpers 4.2 is with recesses for receiving the electrical components 26 educated. The recesses are referred to below as pockets 27 designated. In these bags 27 have the electrical components 26 Space with little play. If, for example, in a later machining process in which the entire connector is heated, the solder joints between individual components and the circuit board of the board should solve solve the electrical components 26 their position as they pass through the pockets 27 held in position so that the solder solidifies again during cooling of the connector and the solder joint between the electrical components and the circuit board continues to exist. The bags 27 may also be provided with a layer of an elastomer or an elastic Po lymer, in which the components 26 are elastically embedded, so that they are kept free of play but elastic.
  • The plug contact pins are stuck with their Pressfitabschnitten 19 in the vias 25 the board 5 and form with this a Pressfit connection. Such Pressfit connections are also referred to as press-in contacts and are in the DIN 41 611 part 5 respectively. DIN IEC 352 normalized. An essential feature of such a pressfit connection is that the pin (here: the pressfit section 19 ) in cross-section a larger diagonal than the via to be contacted 25 having. This creates when pressing the pin into a via an overpressure that is absorbed either by deformation of the via or by deformation of the pin. There are therefore two types of press-fit connections, the solid version in which the through-hole deforms and the flexible design in which the pin deforms. The Pressfit connections of the present embodiment correspond to the solid version.
  • The Pressfit connection is designed such that the necessary Aufsteckkräfte for attaching the board 5 on the plug pins 3 to form the Pressfit connection is as low as possible, so that a certain elasticity and mobility of the plug contact pins 3 regarding the board 5 given is. On the other hand, the Aufsteckkräfte are so large that a permanently secure mechanical and electrical connection between the plug contact pins 3 and the vias 25 the board 5 is guaranteed. In prototypes of the present invention, it has been found that the Pressfit connection is much more suitable than a rigid solder connection, even if the mobility of the plug pins 3 regarding the board 5 is low.
  • At the back is the connector 1 through the second backseal isolator 3.4 completed, the form-fitting in the opening of the rear housing part 2.2 is included. The second back insulation 3.4 again has through holes 28 on, through which a rear portion of the pressfit connections of the plug pins 3 extends.
  • The three insulators 4.1 . 4.2 , and 3.4 are arranged at a distance from each other and each form-fitting enclose the plug contact pins 3 , As a result, the plug contact pins 3 in a plane transverse to the direction of insertion 13 fixed and secured against tilting.
  • Between the board 5 and the rear housing part 2.2 there is an electrically conductive Leitgummiröhrchen 29 , These conductive rubber tubes 29 serves as an elastic contact element 29 , This elastic contact element 29 is in contact with an electrical contact surface of the board and with a low bias between the board 5 and the rear, electrically conductive housing part 2.2 arranged. This will create an electrical connection between the board 5 and the housing part 2.2 formed, which serves as a ground connection. As the contact element 29 is elastic or flexible, is the connection between the board 5 and the housing 2 mechanically decoupled.
  • As electrically conductive elastic or flexible contact element 29 can instead of a conductive rubber tube 29 a contact element may also be provided which consists of a stranded element made of elastic twisted strands (for example in the form of a plug), a spring element with a low spring characteristic, an elastic body which is enveloped by a metal mesh, an elasticized conductive polymer or a conductive elastomer is trained. However, any other elastic or flexible electrical connection is also suitable.
  • 7 shows a second embodiment of a miniaturized connector according to the invention in a sectional view. The structure of the connector 1 according to the second embodiment substantially corresponds to the structure of the connector 1 according to the first embodiment, which is why the same parts are provided with the same reference numerals. The second embodiment differs from the first embodiment only in that no second Rückrückisolierkörper is provided. The plug contact pins 3 be in the case 2 only by means of a first front part insulating body 4.1 and a single backseal body 4.2 held. Between these two insulators 4.1 and 4.2 how are shoulders in turn? 16 the plug contact pins 3 arranged so that the plug pins are fixed in the axial direction. Shoulders 16 store against rotation in the corresponding recesses 15 of the Fronteilisolierkörpers 4.1 , A circuit board 5 is adjacent to a rear wall of the housing part 2.2 arranged. Between the board 5 and the rückwertigen housing part 2.2 a gap of about 6/10 mm is formed, in which there is an electrically conductive spring element 30 which is an electrical connection between the housing 2 and the board 5 manufactures. This spring element 30 is, for example, a simply angled copper sheet. It's with the board 5 soldered and pressed due to its spring action against the inner surface of the housing 2 , In a relative movement of the plug contact pins with respect to the housing 2 will the board 5 together with the plug contact pins 3 with respect to the housing 2 emotional. By providing the spring element 30 will be the electrical connection between the board 5 and the housing 2 even if not interrupted when the distance between the board 5 and the housing 2 one piece enlarged.
  • The back insulation 4.2 has spacers at the corner as in the first embodiment 24 on, located at the back corner areas of the rear housing part 2.2 support. This will cause mating forces on the pins 6 abutment (arrow 1.31 ) from the plug contact pins 3 to the insulating body 4.1 . 4.2 (Arrow 2.31 ) and from the Rückrückisolierkörper 4.2 in the case 2 initiated (arrow 3.31 ). Because the board 5 with respect to the housing 2 is freely movable and with some play in the case 2 is arranged, the insertion forces are not over the board 5 transfer. The board 5 thus remains free of tension. This ensures a long life.
  • A third embodiment of a miniaturized connector with integrated circuit board is in the 8th to 13 shown. It is again a sub-D connector 1 with a housing 2 and arranged in a predetermined grid plug contact pins 3 , In this embodiment, the plug contact pins 3 each from a pair of sub-pins 32 . 33 educated ( 13 ). The sub-pins 32 . 33 are so-called pogo pins, that is, they have a tubular body 34 in which a contact pin 35 is slidably mounted. The tubular body 34 is closed at one end and at the other end is the contact pin 35 a piece out. In the main body 34 there is a spring element that the contact pin 35 applied. The sub-pins 32 . 33 are thus elastically yielding in length by the contact pin 35 into the main body 34 can be inserted and acted upon by the spring element with a corresponding counterforce.
  • The two sub-pins 32 . 33 each have a circumferential shoulder 16 on, each with two laterally flattened surfaces 21 are provided. The in the direction of insertion 13 pointing part pin 32 forms a pin in the direction of insertion to the front 6 for insertion in a corresponding mating connector. The part pin located on the back of the connector 33 forms at its opposite to the plugging direction 13 pointing end a soldering pin 36 which is insertable and solderable in a corresponding hole of a printed circuit board.
  • This connector has four Isolierkör by 4 on. Starting from the plug side 8th are towards the back 9 successively the outer Frontteilisolierkörper 4.4 , the inner front part insulator 4.5 , the inner back part insulator 4.6 and the outer back insulation 4.7 arranged. The outer insulator 4.4 and 4.7 are the same as the Frontteilisolierkörper 4.1 of the first embodiment with externally arranged positioning webs 12 and through holes 14 attached to the diameter of the respective sub-pins 32 . 33 adapted, trained.
  • The two inner insulators 4.6 have essentially the same structure. They each have an outwardly facing substantially smooth surface with two recesses 23 , in the corresponding projections of the outer insulating body 4.4 respectively. 4.7 intervention. Furthermore, in the inner insulators 4.5 and 4.6 Through holes 22 formed, the outwardly gradually to a respective recess 15 expand, which is exactly complementary to the shape of the shoulders 16 the sub-pins 32 . 33 are. In these recesses 15 store your shoulders 16 the sub-pins 32 . 33 torsion. Shoulders 16 are between the respective outer insulating body 4.4 respectively. 4.7 and the respective inner insulating body 4.5 respectively. 4.6 arranged and thereby axially fixed.

The arranged in series inductance can be in a connector with continuous plug contact pins 3 be realized by means of a ferrite. In a connector with an interrupted plug contact pin, the inductance may also be formed by a coil. The inductance of a coil is much more precise than that of a ferrite body, so that such a filter is much more precise than a filter formed with a ferrite body. This is a significant advantage, because in the design of the filter whose tolerances must be considered. If the tolerances are lower, the frequency band to be passed by the filter can be defined much narrower and less spurious frequencies can pass through the filter.

  • Of the C-filter has an attenuation of about 20 dB, the L-filter has an attenuation of about 40 dB and the pi filter and the T-filter each have a damping of about 60 dB. It can be seen that the attenuation of the filter the more complex the more complex they are, the stronger. By the use of a board integrated in the connector can Basically arbitrarily complex filters are provided. Optionally, several boards in the connector in stacked Provide arrangement so that for the individual components there is enough space.
  • The Filters discussed above are passive filters. As part of According to the invention, it is also possible to have an active filter to integrate in the connector. This is about a Plug contact pin of the filter circuit to supply a supply voltage. The filter then includes active elements, such as electrical amplifiers and control components.
