Definitions
- the invention relates to a plug-in system, comprising a plug-in part with at least one contact element and a mating plug-in part with at least one contact point on a contact carrier surface extending approximately parallel to a plug-in direction.
- the plug-in part can be inserted in the plug-in direction into the mating plug part in such a way that the contact element comes into electrical contact with the contact point of the mating plug-in part.
- Such plug-in systems are particularly suitable for the transmission of numerous signals in a confined space.
- the male part has a multiplicity of contact elements and the mating male part has a multiplicity of contact points (or contact pads) on the contact carrier surface, which are brought into electrical contact with the respective associated contact element when plug-in part and mating male part are plugged together.
- the surface at least partially as Contact carrier surface is formed, which carries the contact points.
- the contact points may be formed as exposed, gold-plated contact surfaces or copper, which is applied to the contact carrier surface, or be galvanically finished.
- a "plug-in part” is understood to be an arbitrary plug connector, such as a plug-in board, a socket part, a plug part, etc., which is set up for mating or for coupling with a complementarily designed "mating plug-in part", wherein in a verkuppelten end position electrical signals or Transmitted currents from the contact elements of the male part to the contact points of the mating male part and can be.
- the verkuppelte end position is preferably detachable, so that the male part and the mating male part are again decoupled from each other.
- FIGS. 6a to 6d A conventional plug-in system is shown by way of example and simplified in FIGS. 6a to 6d:
- the mating plug part has one of the contact carrier surface in a transverse, in particular perpendicular, extending to the plug-in direction of contact opposite counter-pressure surface.
- the contact carrier surface is movably held on the mating male part such that it can be displaced in the insertion direction relative to the counter-pressure surface immovably held on the mating male part.
- the contact carrier surface is movably held on the mating plug part so that it is displaceable in the insertion direction in the end position upon insertion of the male part together with the contact element. Only in the end position, the contact element is pressed in the direction transverse to the insertion direction pressing against the contact point, wherein the contact element is received in the end position in the space between the counter-pressure surface and the contact carrier surface and is thereby pressed against the contact carrier surface, so that a reliable electrical Contact between the contact element and the contact point is made.
- the contact carrier surface is held displaceably in the insertion direction on the mating plug part.
- This has the advantage that, unlike conventional plug-in systems, the contact element is not moved under pressure relative to the contact carrier surface during insertion and in so doing grinds over the contact carrier surface or via the contact point. Rather, the contact element can first be brought into a position in which it already positioned the contact point correctly positioned (preferably without it to rest against), and only then is the Contact carrier surface moves together with the male part in the insertion direction, whereby the contact element is clamped in the intermediate space between the contact carrier surface and the counter-pressure surface.
- the invention is based on the recognition that the sliding relative movement between the contact partners in conventional plug-in systems leads to the above-described problems and should therefore be largely avoided.
- a sliding relative movement takes place only between the counter-pressure surface and the contact element, but not between the contact carrier surface and the contact element.
- the contact carrier surface may protrude further in the direction of the plug part than the counterpressure surface. In this case, in the course of the insertion process, first the contact element is positioned correctly with respect to the contact point, and only upon further insertion is the contact element brought into abutment with the counterpressure surface beginning behind in the insertion direction.
- the contact normal force required for signal transmission between contact point and contact element is not generated by the fact that the spring tension of the contact element designed as a contact element acts between a contact surface of the plug part and the contact carrier surface of the mating plug part. Rather, acts according to the present invention, the spring bias of the contact element designed as a contact element preferably between two surfaces of the mating connector, namely between the counter-pressure surface and the contact carrier surface.
- the spring force can be absorbed by a component which is not involved in the electrical contact, namely the counter-pressure surface.
- a reliable contact force between the contact element and the contact point can be ensured that the at least one contact element is flexible and preferably designed as an elastic contact spring. Especially many mating cycles under constant contact force can be achieved if the contact element is designed as a leaf spring element.
- the leaf spring element is received in the end position in a space between the contact carrier surface and the counter-pressure surface and is thereby pressed against the contact point.
- the dimension of the leaf spring element in the relaxed state in the pressing direction is greater than the distance between the contact carrier surface and the opposite counter-pressure surface, preferably more than 1, 1 times, in particular more than 1 , 2 times or more. In this way, a good clamping effect is achieved without an excessive insertion force is required for the insertion process.
- the leaf spring element has a first leaf spring part projecting cantilevered essentially in the insertion direction and having a first abutment region for bearing against the contact point.
- the leaf spring element may have a second leaf spring part bent back from a front end of the first leaf spring part with a second contact surface for engagement with the counterpressure surface for exerting pressure on the leaf spring element in the contact pressure direction.
- the dimension of the leaf spring member in the pressing direction is preferably measured between the first and second abutment portions.
- the second abutment portion of the counter-pressure surface against pressed the first contact area and the leaf spring element in the pressing direction thereby compresses a total of elastic.
- the second leaf spring part has an at least partially oblique with respect to the insertion direction extending front surface, so that the leaf spring part is gradually compressed during insertion by pressure contact with the counter-pressure surface and the contact force can be gradually built up.
- Such a configuration of the contact element allows a well-dosed and reliably acting contact force in the end position.
- all contact elements may be similar or substantially identical, wherein influence can be taken on the insertion force required for coupling by selecting the material thickness, the dimension in the pressing direction and the shape of the leaf spring elements.
- the plug-in system according to the invention is preferably designed for transmitting a plurality of signals, wherein in this case the plug part a plurality (eg. 5, 10, 30 or more) in a width direction (B) juxtaposed contact elements and the mating plug a plurality of at the Contact carrier surface in the width direction (B) may have juxtaposed contact points that come into contact with a respective associated contact element upon insertion.
- the width direction is transverse, in particular perpendicular, to the insertion direction and the pressing direction.
- the contact elements are preferably in the form of contact springs starting from a spring carrier of the plug-in part in the direction of the mating plug-in part, wherein the contact points are introduced as contact pads next to one another at corresponding distances in the contact carrier surface.
- the mating plug part has a plate element such as a printed circuit board (PCB) with two opposing contact carrier surfaces and / or that the plug part at least one pair of contact elements of two in the Pressing (H) has oppositely arranged contact elements, between which the plate member is insertable.
- a plate element such as a printed circuit board (PCB) with two opposing contact carrier surfaces and / or that the plug part at least one pair of contact elements of two in the Pressing (H) has oppositely arranged contact elements, between which the plate member is insertable.
- both the upper and the lower boundary surface of the board is at least partially configured as a contact carrier surface with contact points for contacting contact elements, wherein both the upper and the lower boundary surface of the board can carry numerous in the width direction B juxtaposed contact points.
- the opposing contact elements of the contact element pair may be arranged substantially symmetrically with respect to.
- the platinum level which simplifies the structure and the contact.
- a distance A between the contact elements of the contact element pair substantially corresponds to the thickness of the plate element.
- the plate element first passes without contact pressure, but in the pressing direction substantially free of play, in the space between the contact elements of the contact element pairs until the contact elements face each associated contact points on the two sides of the board. Only then does the pressing against the contact points in the pressing direction take place in that the plate element is displaced together with the contact elements of the contact element pairs relative to two counter-pressure surfaces until the contact elements are pressed by the counter-pressure surfaces in the pressing direction on both sides in the direction of the plate element.
- This symmetrical structure leads to a symmetrical contact pressure on the two oppositely directed contact carrier surfaces of the plate element and thus to a particularly uniform and stable contact.
- the mating plug part prefferably has two, three or more, in particular eight plate elements, such as sinkers, each extending in the plug-in direction (S), wherein preferably both main piatine surfaces are formed at least in sections as contact carrier surfaces ,
- the individual plate elements are included preferably arranged one above the other in the pressing direction. The plate elements are then inserted substantially without contact pressure between each pair of contact element pair, and then the contact elements are each pressed by means of pairs of opposing counter-pressure surfaces to the associated contact points.
- the first force peak can be set higher than the following force peaks, being pushed through to the end. This ensures that everything is complete.
- the plate elements are arranged in each case displaceably and preferably in the pressing direction substantially centrally between two counter-pressure surfaces of the mating plug.
- the first counterpressure surface is provided for pressing contact elements against the first contact carrier surface of the plate element
- the second counterpressure surface is provided for pressing the respectively opposite contact elements against the opposing contact carrier surface of the plate element.
- the production of a plug-in system according to the invention can be simplified in that the plate elements each interspaces one of Go through counter-surface having lamellar body, wherein preferably the lamellae of the lamellar body facing the plug-in part and / or obliquely with respect to.
- the insertion direction extending ramps may have.
- the run-up slopes can gradually pass into the running parallel to the insertion counterpressure surfaces.
- the lamellar body may be formed in one piece and carry a plurality of each having two counter-pressure surfaces having fins.
- the slats of the slat body are each attached separately to a housing of the mating connector. It is important that the individual boards protrude through the spaces between the slats, so that the contact elements and the boards are already correctly positioned relative to each other when the contact elements enter into the spaces between the slats.
- the plug-in part preferably has at least one stop surface on which a front surface of the at least one plate element abuts when it is plugged in and from which the plate element is pushed in the plug-in direction.
- a low-wear, good contact enabling Weg istösvorgang can be achieved in that the male part of an intermediate position in which the contact elements their respective contact points each already positioned correctly, but substantially pressure-free, opposite, is displaceable in the end position, in which the contact elements clamped between each plate member and a counter-pressure surface and thereby pressed to the associated contact point.
- the abutment surface of the male part is preferably arranged such that the front surface of the plate element abuts against it, when the contact elements are positioned correctly positioned the contact points. From this point, the plate member is advanced in the direction of insertion relative to the counter-pressure surfaces. In order to allow a mobility of the contact carrier surfaces or the plate elements in the insertion direction, the plate elements are preferably guided displaceably in extending in the insertion direction guide slots. Preferably, each contact carrier surface or each plate member is associated with at least one biasing element such as a spring element, against the bias of the plate member is displaceable in the insertion direction.
- the plate elements Prior to insertion of the male part, the plate elements are urged by the biasing elements towards the male part to ensure that plate elements are in an interface-side position when inserted.
- the required insertion force can be adjusted by the spring force of the biasing elements.
- a stop (for example a shoulder of the disk body) may be provided on the mating plug part, against which the plug-in part strikes upon reaching the end position.
- the spring elements can each be provided as leaf springs behind the guided in guides plate elements.
- each plate member is assigned at least one leaf spring of the leaf spring comb, which is the respective plate element in the direction of the male part.
- two Blattfederkarmme each provided with a leaf spring per plate element.
- the biasing elements, the plate elements with the contact carrier surfaces and / or preferably formed as lamellae counter-pressure surfaces can be accommodated in a common housing of the mating plug-in part, in which the plate elements are arranged one above the other in layers in the pressing direction.
- a number of contact element carriers corresponding to the plate elements can be accommodated in a common housing of the plug-in part, in which the contact element carriers are arranged in layers in the Pressing are arranged one above the other. From a front side of each contact element carrier are preferably formed as contact springs contact elements in front of each other. In this case, two opposing rows of contact elements are preferably provided in the pressing direction, wherein in each case a plate element is insertable between the individual contact element pairs of these two rows.
- the invention also relates to a plug-in part of a plug-in system according to the invention and a mating plug-in part of a plug-in system according to the invention.

- Fig. 6a to 6d four steps in the course of a plug-in operation, in which a consisting of a male part and a mating male part conventional plug-in system is verkuppelt.
- the present invention will be explained with reference to a plug-in system designed in a particularly advantageous manner:
- the plug-in system 100 shown in FIG. 1 consists in principle of a plug-in part 10 and a mating plug-in part 20.
- the plug-in part is shown in detail in FIGS. 2 and 3 and the mating plug-in part is shown in detail in FIGS. 4a to 4d.
- a plurality of contact element carrier 60 are held stationary (see Figures 2 and 3).
- cables are soldered onto the printed conductors of a printed circuit board which emerge from the housing 65 on the so-called “cable side.” They serve for further signal transmission to other components which have no significance for the present invention.
- contact elements 30 are on the contact element carrier 60 both at the top and at the bottom are applied in the form of contact springs which protrude in the insertion direction S from the contact element carrier 60.
- Two contact elements 38, 39 lying opposite one another are referred to below as contact element pair, which are ideally soldered directly onto the conductor tracks of the contact element carrier 60 38, 39 of the contact element pairs is a free space formed with a distance A, which is at least so large that the thickest, provided for immersion of the mating connector 20 board 40 can dive substantially frictionless as a contact partner between these contact elements 38, 39.
- the contact elements 38, 39 of the contact element pairs are at least partially opposite each other in a pressing direction H which is perpendicular to the insertion direction S.
- a pressing direction H which is perpendicular to the insertion direction S.
- numerous pairs of contact elements (here by way of example 34) are arranged side by side in a width direction B which is perpendicular to the insertion direction S and the pressing direction H.
- a contact element carrier is thus set up to transmit 68 signals, wherein eight contact element carriers 60 are received one above the other in the housing 65 in the pressing direction H.
- more or less contact elements per contact element carrier 60 or more or fewer than eight contact element carriers 60 may be provided in the housing 65.
- the contact elements 30 each have a first leaf spring part 32, which is fastened to the contact element carrier 60 and projects substantially in the plugging direction S from the contact element carrier, with a first contact region for electrically contacting a contact point 44 of the mating plug part 20 ,
- the contact element 30 is bent back and has one of the front end of the first leaf spring member 32 substantially opposite to the insertion direction S returning second leaf spring member 34 with a second abutment portion for abutment against a counter-pressure surface 52 of the mating connector 20 in the end position II.
- the contact elements 30 are arranged elastically compressible in the pressing direction H.
- FIG. 4 b shows the mating plug part 20 obliquely from behind and FIG. 4 d shows a partial area of the mating plug part 20 in a sectional view.
- a housing 45 which is also open on two sides, laterally opposite guide slots 46 can be found.
- the number and exact execution of the guide slots 46 are irrelevant to the further considerations.
- plate elements are inserted in the form of boards 40, whose upper and lower main surfaces of the interface side (the side which is provided for coupling with the male part 10 and the male part 10 when plugging faces) as opposing contact support surfaces 42, 43 are formed.
- the contact carrier surfaces 42, 43 each have a plurality of juxtaposed in the width direction of contact points 44, which are provided for electrically contacting the contact elements 30.
- the design of the spring elements 70 is exemplary here. Any other shape that pushes the boards 40 against the stop in the guide slots 46 is conceivable.
- the boards 40 are thus movably mounted in the insertion direction S, where they are in the unmated state in an interface-side end position in which they project in the direction of the plug-in part 10 to be inserted.
- a lamellar body 50 This is designed such that it has a plurality of parallel slats 51. In cross-section (see Fig. 4d), these slats 51 are substantially rectangular, with each slat surface side top and bottom of a small slope, the so-called. Run-on slope 54 has. The run-on slopes 54 each pass into the counter-pressure surfaces 52 of the slats 51, through which the contact elements 30 are pressed against the contact points 44.
- the lamellar body 51 is installed in a suitable manner fixed in the housing 45 (eg pressed, glued or injected directly with), so that the run-on slopes 54 are directed towards the interface.
- the boards 40 are received in the housing 45 in such a way that, on the interface side, they project substantially centrally through the intermediate spaces between the lamellae 51. Also, the housing 45 has elements for pre-centering, in the form of two pins 49th
- the contact elements 30 and the pads 44 (landing pads) on the contact support surfaces 42, 43 of the boards 40 are optimally to each other aligned, but still not touching. It should be remembered that the boards 40 are resiliently mounted and slidable towards the cable side. This becomes important now, since the male part 10 and the mating male part 20 are pushed further into one another, but the sinkers 40 are already pressed against the abutment surfaces 62.
- the lamellar body 50 is now used (see FIG. 1c).
- the counter-pressure surfaces 52 formed by the fins 51 run with their run-on slopes 54 on the contact elements 30 so that they are inserted into the space between boards 30 and fins 51 and pressed against the already positioned contact points 44 of the boards 40.
- the contact carrier surfaces 42, 43 are thus moved together with the correctly positioned contact elements 30 relative to the stationary on the housing 45 held counter-pressure surfaces 52.
- the electrical contact is finally made (see Fig. 1d).
- run-up bevels 54 can be offset from one another in the insertion direction in order to reduce the value of the maximum insertion force. However, this is not shown here, since in this embodiment is not necessary.
- the maximum contact force is reached at the end of the chamfers 54, which then in pass straight substantially parallel to the insertion direction S extending counter-pressure surfaces 52, whereby it is achieved that the contact force remains constant at the desired value.
- the male part 10 and the mating male part 20 are pushed further into each other (the relative position of the contact elements 30 and the contact points 44 on the contact carrier surfaces 42, 43 remains unchanged) until the housing 65 abuts against the lamella body 50.
- the plug-in process is complete. When loosening the plug connection, the procedure described above takes place in the reverse order.
- the plug-in system according to the invention offers, in particular, the following advantages over the conventional plug-in systems: a) Optimized wear behavior, since the contact elements do not slide over the entire plug-in path on the contact pads, but come into press contact only if there is no relative movement between the contact element and contact point. Therefore, less abrasion, easier mating (no frictional force against the mating direction from the contact elements on the contact pads), better pre-centering before contact is made.
- the contact springs can be made simpler, cheaper and more reliable. Likewise, the packing density (number of contacts per unit area) can be increased because the contact elements can be made smaller.
- the connector system is scalable and optimally adaptable to the respective application.
- the plug-in system according to the invention is not limited to the embodiment shown in the figures.
- the plug-in system does not necessarily a plurality of contact elements and contact points, but can also provide only a single contact path.
- the circuit boards symmetrically loading, opposing contact elements in the form of contact element pairs that contact both major surfaces of the board, but offer special stability and compactness benefits.
- the plug-in system according to the invention due to the exactly definable insertion forces without risk of wear set up particularly well for transmitting a plurality of signals and therefore preferably has more than 50, in particular more than 100 contact elements and associated contact points.
- the contact elements are not yet under pressure at the contact points after plugging mating part and mating plug in the plug S, but only by another operation (eg. Applying pressure on the contact element carrier, adjusting the lamellar body, actuation of a additional part, etc.) brought into the final position in which they rest under pressure at the contact points.
- another operation eg. Applying pressure on the contact element carrier, adjusting the lamellar body, actuation of a additional part, etc.
- the contact elements are spread apart before the insertion process and are relaxed after plugging by means of various parts and then contact the board under pressure.
- double boards which are clamped together after insertion.
- the contact elements or the contact element carrier carrying the contact elements can be movable (for example floatingly mounted).
- contact element carrier There is not necessarily a contact element carrier available.
- the contact elements may, for example, be applied directly to plate elements such as circuit boards (analogously to the contact points), for example by soldering.
- the boards of the male part may be movably held in the insertion direction on the male part.
