Definitions

  • the invention relates to a contact element for arranging between two contact base bodies to be connected to one another in an electrically conductive manner.
  • Such a contact element has at least two strips and a series of webs which are arranged between them and which are connected to them, which are connected with one another and which are resilient and resilient, normally elongate lamellae, which touch mutually facing, spaced-apart contact surfaces of the two contact base bodies and thereby conductively connect them to one another can.
  • Such contact elements can be used in particular for electrical connection devices in which relatively large currents, for example at least 20 A, are to be transmitted from one contact base body to another contact base body.
  • the two contact base bodies can normally be separated from one another.
  • the contact member is normally held detachably on one of the two contact base bodies and, for example, is frequently arranged in a groove of such a body.
  • the distance between the contact surfaces of the contact base bodies to be connected to one another may vary within a certain tolerance range due to manufacturing inaccuracies and, in particular, because of the play present in many connecting devices - for example in connection devices serving as plug connections or switches.
  • the webs of a contact member should therefore spring well and in particular have sufficient spring travel to be able to compensate for the tolerance range of the contact surface distance.
  • Various known contact members consist of a piece of a strip with two edge strips running along the strip edges and a series of interlocking webs arranged between them and connected with them, which form elongate lamellae, run at right angles to the edge strips and have a central section, which is connected to the two edge strips via a constriction.
  • the mutually facing edges of successive webs along the row of webs - even if they are in an unobstructed state - are separated from one another over their entire lengths by slots.
  • the contact members are formed, for example, from sheet metal, which consists of a copper-beryllium alloy, has been hardened by heat treatment after shaping and has silver-plated surfaces.
  • a contact member which has two parallel, straight edge strips and webs separated from one another by slits, the two edges of which are bulged in the region of the central section and bulged mirror-symmetrically to one another.
  • the elongate webs of this known contact element In order for the elongate webs of this known contact element to provide a reasonably sufficient suspension, they must have a certain minimum width transversely to their longitudinal directions, which is dependent on the spacing area of the mutually facing contact surfaces of the two contact base bodies. Since there are still slits between the successive webs, the grid distance, ie the distance of corresponding points along the row of webs from adjacent webs, is also greater than the minimum width of the webs mentioned.
  • the known contact member therefore has a measured in the longitudinal direction of the row of webs Unit of length only relatively few webs and allows only a correspondingly low power transmission per unit of length mentioned.
  • the wavy or meandering edge strips according to US-A-3 895 853 and the corresponding DE-C-2 243 034 furthermore have a height in a longitudinal section which is considerably greater than the material thickness of the contact member. This can make it necessary that grooves provided for receiving the contact members have to be formed deeper than in the case of contact members with smooth, wave-free edge strips. In addition, one may be forced to provide differently designed grooves instead of dovetail grooves that are often used to receive contact elements.
  • a contact member known from DE-A-2 634 374 has two in a side view in the finished contact member zigzag, i.e. edge strips forming angular waves and webs arranged between them. Each web has two web edges that are mirror-symmetrical to one another in an unobstructed state. Each web edge has two bulges, which are separated by an indentation in the middle of the web edge.
  • the zigzag-shaped edge strips of this known contact element result in disadvantages similar to those of the wave-like and / or meandering edge strips of the previously described contact elements known from US-A-3 895 853 and DE-C-2 243 034.
  • the invention is therefore based on the object of creating a contact element which has the disadvantages of the known contact elements fixes and can have, for example, with a predetermined spacing area of the contact surfaces of contact bodies to be electrically conductively connected to one another, a large number of webs giving a large spring deflection per unit length of the web row and can be produced economically and is unbreakable when used.
  • the invention further relates to a method for producing the contact member, the method according to the invention having the features of claim 10.
  • the two basic contact bodies can, for example, together with at least one contact element, belong to a connecting device which serves to form an electrical plug connection, for example one basic contact body having a square cross-section - namely rectangular and flat - or circular contact pin of a plug and the other basic contact body, for example one can form a flat and / or fork-shaped or hollow cylindrical contact of a socket which is provided for attachment to a solid object of any kind or as a coupling socket for connection to a portable line.
  • the contact element can be attached to the contact body belonging to the socket or to the contact body forming the plug pin.
  • a Contact base body serving busbar are provided, on which at least one other, for example fork-shaped contact base body can be detachably attached.
  • Contact base bodies of this type can be used, for example, for the formation of an electrical device with at least one immovably fastened busbar and displaceably guided inserts, each of which has at least one contact element which can be plugged onto the or a busbar.
  • a connecting device designed as a switch can be provided, in which at least one contact element is attached either to the fixed or to the movable contact body of the switch.
  • the connecting device shown in FIGS. 1, 2, 4 and 5 has two dimensionally stable, metallic, electrically conductive contact base bodies 1 and 2 and a flexible and resilient, likewise metallic, electrically conductive contact element 3.
  • the one, first contact base body 1 forms a flat, first contact surface 1b and the other, second contact base body 2 has a recess, namely a groove 2a with a dovetail cross section, the base of which forms a flat, second contact surface 2b.
  • the two contact base bodies 1, 2 can optionally be held together and not connected by means of holding and / or connecting means according to FIGS. 1 and 5, not shown. If the two contact base bodies 1, 2 are held together, the contact base body 1 lies with its flat contact surface 1b on the contact base body 2 such that the two contact surfaces 1b, 2b face each other and are parallel to one another and are at a distance d equal to the depth of the Groove 2a is.
  • the contact element 3 is held in the groove 2a of the contact base body when the contact device is in use and is secured against slipping out of the groove by holding means, not shown, for example by pins or end plates releasably fastened at the ends of the groove or by pressed-in end sections of the groove walls.
  • the contact element 3 which is shown separately in FIG. 3, consists of a one-piece, band-shaped part and has two edge strips 3a and a series of spring webs 3c which are arranged between them and are connected with them and interlaced with respect to them.
  • the two edge strips 3a are generally straight and parallel to one another and have a shaft-free inner section which is at least flat with uninterrupted webs and a projection 3d projecting outwards from the inner section per web 3c.
  • the free end portions 3e of the projections 3d formed by the outermost portions of the two edge strips 3a are against the remaining areas of the edge strips 3a lying in one plane when the contact element is relaxed Angled in the longitudinal direction of the row of webs rectangular cross-section so that they are inclined at least approximately parallel to the lateral boundary surfaces of the groove 2a against the bottom thereof forming the contact surface 2b.
  • the outer edges of the two edge strips 3a are rounded off at the free ends of the projections 3d and in the spaces between the latter and namely are formed by semicircles, so that the outer edges when the edge strips are brought into a flat shape, and / or form a continuous wavy line in the top view drawn in FIG. 3.
  • the webs 3c are elongated and each form a lamella.
  • Each web has a central section 3f and two constrictions 3g arranged on sides facing away from it, each of which constricts them with one of the edge strips.
  • the one, first web edge 3h of each web 3c forms a bulge 3i in the middle of the middle section 3f.
  • the other, second web edge 3k of each web has an indentation 3m in the middle of the middle section 3f.
  • the bulges 3i have, for example, two straight flanks which are inclined away from their roots towards the center, and a vertex which is approximately straight in the case of unconstrained webs and in the plan view shown in FIG. 3, the two flanks being continuously connected to the vertex by convexly curved transitions .
  • the indentations 3m of the ridge edges 3k are complementary to the indentations 3i of the ridge edges 3h and thus have in particular a base which is complementary to the apex of a bulge and flanks approaching one another towards this. It should be noted that the entire flanks and / or the entire vertices of the bulges 3i could also be slightly convex. Accordingly, the entire flanks and / or the entire bases of the indentations could then be curved 3m concavely.
  • the bulges and the indentations of the web edges and the sections of the webs delimited by the bulges and indentations are therefore approximately trapezoidal and / or arched.
  • Each web has in the in the third visible top view roughly the shape of the crank of a crankshaft.
  • each bulge 3i - with the exception of the bulge located at the lower end of the web row in FIG. 3 - protrudes into the indentations 3m of the web 3c concerned along the Row of webs immediately adjacent to the web.
  • the webs are separated from one another by cuts made without material removal, so that the web edges 3h, 3k of webs 3c immediately following one another along the row of webs - if these are in an unobstructed state - in the middle sections 3f and in particular Also at least approximately touch the bulges 3i and indentations 3m.
  • each hole 3n consists of an elongated hole or slot and has, for example, a wider section at its end adjoining an edge strip 3a and a narrower section at its other end.
  • the edge of each hole 3n has a curved semicircular end portion at the wider end of the hole.
  • the longitudinal section of the hole edge which adjoins this and belongs to one of the first web edges 3h extends in a straight line up to the bent and / or angled end section of the hole edge which is present at the narrower end of the hole.
  • the longitudinal section of the hole edge belonging to one of the second web edges 3k is stepped and has two mutually offset, straight sections parallel to the other longitudinal edge of the hole.
  • the inclined flanks of the bulges 3i and the indentations 3m directly adjoin the edges of the holes 3n and thus open to a certain extent into the holes 3n.
  • each hole 3n is arranged approximately in the same longitudinal region of the contact element as a projection 3d of the edge strip 3a located closer to the hole 3n in question.
  • the webs 3c are - as already mentioned - interlaced and resilient.
  • the entanglement occurs when the contact member is produced, starting from an originally flat sheet metal part, especially by twisting the constrictions 3g, which also serve as torsion springs and cause a large part of the spring properties of the webs.
  • the webs are interleaved in such a way that their central regions are inclined against a contact plane touching the contact element and parallel to the contact surfaces 1b, 2b, the angle of inclination being 30 ° to 50 ° and, for example, approximately 40 ° when the contact element is relaxed. As can be seen from FIGS.
  • the apex regions of the bulges 3i and the edge regions of the webs located between the indentations 3m and the constrictions 3g are bent or possibly angled in a cut running along the row of webs such that the webs do not with their edges present at the web edges, but with surface areas on the contact surfaces 1b or 2b.
  • 3 straight lines 6 are drawn in FIG. 3, each of which has a second web edge 3k at its most protruding crosswise to the web, facing away from one another on the side of the indentation 3m of the web in question between this and touches one of the edge strips 3a touching points.
  • These points of contact are formed by the two sections of the second web edge 3k which are parallel to the straight line of contact 6 and are located between the narrowest sections of the constrictions 3g and the flanks of the indentations and adjoin the narrower sections of the holes 3n.
  • each line of contact 6 does not penetrate the second web edges 3k anywhere, apart from the penetrations of the hole edge sections delimiting the holes 3n against the strips 3a, which each connect a first web edge 3h and a second web edge 3k to one another.
  • each line of contact 6 also runs through the centers of the wider sections of two holes 3n.
  • FIG. 3 also shows a constriction center axis 7 which runs parallel to the line of contact 6 through the centers of the narrowest sections of the two constrictions 3g of a web 3c.
  • the lines of contact 6 and constriction center axes 7 form with the center line 5 of the web row an angle alpha which is different from 90 °, preferably at least 80 ° and for example approximately 85 °.
  • the grid distance a is also shown in FIG. This is understood to mean the distance, measured parallel to the longitudinal direction of the row of webs and therefore parallel to the center line 5, of corresponding points from two webs immediately following one another along the row of webs, so that the grid distance a is in particular also equal to the distance of the apex from measured in the direction mentioned immediately successive bulges 3i or immediately successive lines of contact 6. Since the middle sections 3f of adjacent webs are separated from one another only by cutting lines, the dimension of the middle section of an uninterrupted web measured parallel to the center line 5 is approximately or exactly the same as the grid distance a.
  • FIG. 3 also shows the distance e, measured parallel to the center line 5, of the apex of a bulge from the line of contact 6 of the web in question.
  • f and g denote the distances between the apex of a bulge 3i and the line of contact 6 of a web from its constriction center axis 7, the distances f and g being measured at right angles to the line of contact 6 and the constriction center axis 7.
  • the distance c and the contact surface distance d are coordinated with one another in such a way that the distance c is greater than the distance d, namely namely approximately three to eight times greater than the latter.
  • the bulges 3i and indentations 3m are dimensioned such that the grid distance a is preferably at least 30% and, for example, approximately 50% smaller than the distance c of the apex of a bulge from the line of contact 6 of a web. Since the distance e by the reciprocal of the sine alpha is greater than the distance c, the ratio a / e is accordingly somewhat smaller than the ratio a / c.
  • the distance f of the apex of a bulge 3i from the constriction center axis 7 is preferably at least 50% greater than the distance g of a line of contact 6 from the constriction center axis 7, f being approximately twice the size of g, for example.
  • the contact member 3 is inserted into the groove 2a of the contact base body 2 and if it is at a distance from the contact base body 1 according to FIGS. 2, 4, the bulges 3i protrude from the groove 2a, the contact member being in a largely relaxed state. 5, however, when the contact base body 1 bears against the contact base body 2, it engages with the contact surface 1b on the bulges 3i of the webs 3c and presses them against the contact surface 2b formed by the groove base, as a result of which the angle of inclination by which the central region of the webs is inclined against the contact surfaces is reduced.
  • Each web 3c then lies with a first contact area located at the apex of its bulge 3i on the first contact surface 1b formed by the first contact base body 1. Furthermore, each web rests with two second contact areas on the second contact surface 2b formed by the second contact base body 2.
  • the two second contact areas of a web 3c are formed by the sections of the second web edge 3k which are located between the narrowest points of the constrictions 3g and the indentation 3m and which adjoin the narrower sections of holes 3n and touch a straight line 6.
  • the distance of the first contact area of a web is approximately equal to the distance c and, because of the bending of the edge areas of the web forming the contact areas, is slightly smaller than the distance c.
  • the grid distance a is therefore also smaller than the distance of the first contact area of a web from its second contact areas measured in the manner mentioned.
  • connection device having the contact element 3 can be designed, for example, in such a way that the two contact base bodies 1, 2 are displaced relative to one another at right angles to the longitudinal direction of the groove 2a when disconnecting or establishing an electrical connection, and that the contact base body 2 held contact member 3 slides at right angles to the longitudinal direction of the web row along the contact surface 1b.
  • the slightly different value of the angle alpha and the bending of the edge regions of the webs 3c touching the contact surfaces improves the sliding ability of the contact member 3 on the contact surface 1b and reduces the generation of grooves in the contact surfaces.
  • the described shapes of the webs 3c and holes 3n ensure that the webs 3c only touch the contact surfaces 1b, 2b in the intended contact areas. If the contact element 3 slides along the first contact base body 1 during the disconnection or establishment of an electrical connection, it is achieved in particular that the first web edges 3h, in addition to their bulges 3i, have no corners which act on the contact surface 1a during the sliding processes.
  • the projections 3d of the edge strips 3c make it possible to achieve good anchoring of the contact element 3 in the groove 2a and great flexibility of the edge strips 3c.
  • the rounding of the edge sections of the free ends of the projections 3d make it easier to move the contact element 3 when it is introduced into the groove 2a and when the contact element 3 is possibly pulled out of the groove 2a.
  • the described design and dimensioning of the contact element ensures that it has a relatively small grid distance a with respect to the distance d between the contact surfaces and therefore has a relatively large number of webs 3c per unit length.
  • the contact member accordingly enables a large current to be transmitted from one of the two contact base bodies 1, 2 to the other contact base body.
  • the distance d between the contact surfaces can vary within a certain tolerance range. Since the grid distance a is smaller than the distance c and accordingly c larger than a, the webs can spring well despite the small grid distance and can compensate for large tolerances of the distance d by a large spring travel.
  • the contact element 3 is formed, for example, from a sheet metal part which consists of a copper-beryllium alloy and the surfaces of which are coated with silver or another electrically conductive and corrosion-resistant coating material.
  • This has transport means, not shown, in order to transport the band-shaped sheet metal part 11 step by step in the transport direction parallel to its longitudinal direction and designated by an arrow 13.

  • the transport means mentioned transport the strip-shaped sheet metal part by a distance which is equal to the grid distance a or preferably equal to an integral multiple thereof.
  • the punching tools punch a pair of holes 3n and preferably a plurality of pairs of holes 3n in the sheet metal part at each cycle. Furthermore, in the same cycle or in a separate, preceding or following cycle, length regions of the outer edges of the edge strips 3a are punched out.
  • the sheet metal part 11 then becomes the cutting tools 14, 15 transported.
  • the or each pair of cutting tools 14, 15 then separates the sections of the sheet metal part 11 which subsequently form the central sections 3f of adjacent webs 3c by a cut along a cutting line which extends from a hole 3n into the hole 3n associated therewith.
  • the cut is made by a shearing process without the material of the sheet metal part being removed between the two web middle sections.
  • the sheet metal part 11 is divided into the edge strips 3a and webs 3c by these stamping and cutting and / or shearing processes.
  • the intended shapes of the webs 3c and projections 3d are then produced in at least one cycle following the cutting and / or shearing process.
  • the sheet metal part can then be cut into pieces with the length provided for the contact members, hardened by means of thermal treatment and galvanically silvered or provided with coatings made of another coating material. In this way, contact organs can be produced economically. It should be noted that the order of the operations described can be changed.

Furthermore, a contact element 53 is provided, which is configured, for example, the same or similar to the contact element 3. While the second contact base body 2 shown in FIGS. 1, 2, 4, 5 has a groove 2a, in the connection device according to FIG. 9, for example, both contact base bodies 51, 52 can consist of completely flat plates.
