  • the invention relates to an electrical connection element, in particular an in an insulating housing, arranged as a pin contact or socket contact trained connecting element with a plug side and a Connection end for contacting a stranded wire, as well as a housing for receiving such a connection element.
  • connection elements are required to make an electrical connection between an electrical conductor with a plurality of strands and a connection end of an electrical contact pin or a contact socket manufacture, but no special tools required is.
  • connection principles There are a number for connecting electrical conductors to a contact element of connection principles known in the art, such as by means of soldering, via Screw connections, through cage clamp connection or also through crimp connections.
  • connection principles such as soldering in industrial connection technology constantly due to the effort is pushed back that screw connections as well as cage clamp spring connections have a relatively large space requirement, and crimp connections each require special tools.
  • the invention is therefore based on the object of a connecting element the kind mentioned at the outset in such a way that a connection technology between an electrical conductor and a connection element is realized, the at least comparable contacting data, such as contact resistance and has gas-tight connection points, such as one with a crimp connection, but without the special Tool of the crimping tool.
  • connection end is similar to a saw tooth has a shaped contour, being perpendicular to the direction of insertion Pointing flanks are provided that a resilient on the connection end Sleeve is pushed on that the sleeve by means of a wedge element is expanded, and that in the space between the connection end and the strands of the stranded conductor inserted up to a stop, after removing the wedge element, with a radially acting force are pressed into the sawtooth-like contour by the resilient sleeve.
  • connection end has a sawtooth-like contour, perpendicular to the direction of insertion Flanks pointing to the connection end are provided a resilient sleeve is slid onto the sleeve with two at 90 ° to each other axially extending slots is provided, segments are formed, which extend to a rear end, and wherein hook-shaped on the parts of the segments pointing into the interior of the sleeve Formations are formed by means of which the sleeve on the Connection end is held.
  • Another object of the invention is a housing for receiving an electrical connection element so that it is simple can be produced and the connection elements are held securely therein.
  • the housing is made in two parts is and from a plug-side housing part and a connection-side Housing part consists, with recesses within the housing part Recording the pin contact are provided.
  • a connecting element designed as a pin or socket contact with a serrated connection end is provided, which of a resilient Sleeve is included.
  • One inserted between the connection end and the sleeve electrical conductor with a large number of strands is applied by the Spring force of the sleeve permanently on the tips of the sawtooth-like Contour of the connection end pressed so that a vibration-proof, with almost the same strength and contact reliability Connection between a contact element and the electrical conductor is achieved as with a crimp connection, but with a special one Crimping tool is required for assembly.
  • connection cross section of the electrical conductors for the connection element according to the invention comprises a larger variation range than is possible with a crimp connection. Due to the small size, an increased number of contacts can be accommodated in the same space in a plug housing than is possible, for example, when using cage clamp springs.
  • the contacting process is advantageously designed such that the sleeve provided with a longitudinal slot has an enlarged diameter by means of a wedge element that can be inserted therein, so that an electrical conductor with a plurality of strands can be inserted between the connection end and the sleeve.
  • the resilient sleeve presses the strands onto the concentrically arranged teeth or into the interstices of the sawtooth-like connection area, so that a mechanical undercut is formed by the tooth tips, as a result of which the electrical conductor is pulled out or pulled out of the sleeve is hardly possible.
  • Another advantage is the optical signaling of already attached or not yet fixed electrical conductors in a plug housing comprising several connections: when all wedge elements protrude from the housing, the corresponding electrical conductors are also firmly connected to the contact pins or contact sockets. It can advantageously be provided that the wedge elements are contrasted in color with respect to the housing.
  • a connection element which is designed such that the contact pins or contact sockets with the sleeve can be inserted directly into an already known connector housing.
  • a variant with a rolled sleeve is provided, in which the lateral surfaces are arranged to overlap, the blade of a screwdriver, with which the diameter of the sleeve can be enlarged, being inserted into a wedge opening at one end of the sleeve.
  • the edge of the inner jacket surface slides along the overlapping jacket surface, so that the strands inside the sleeve do not reach the outside.
  • connection a similar, advantageously detachable is To achieve connection, similar to a crimping process, however is not solvable.
  • FIG. 1 An exploded perspective view of an individual connection element is shown in FIG. 1. If a large number of such connection elements are combined in an insulating housing, known plug connections are produced with a large number of connection contacts arranged in rows and columns.
  • the example shown is a connecting element designed as a pin contact 10, which is inserted into an insulating housing 1, which is again formed from two joined partial housings 2, 3.
  • a mating connector with corresponding socket contacts is provided in an equivalent manner, but is not shown here.
  • One part of the housing represents the plug-side housing part 2, with recesses 5, 6 for inserting the pin contact 10 with the sleeve 20, while in the second part, the connection-side housing part 3, a recess 31 for the funnel-shaped side of the sleeve and funnel-shaped slats 32 and an opening 33 for an electrical conductor are provided.
  • the two housing parts can be connected to one another and are arranged one behind the other such that the respective openings are aligned with one another.
  • the pin contact 10 is guided in an opening 5 which has an elongated guide through an annular projection 8.
  • the pin contact 10 is inserted up to its stop 16, a plate-shaped formation between the plug side 12 and the connection end 13, together with the sleeve 20 pushed onto the connection end into the recess 5, 6, the plug side 12 of the pin contact on the plug side of the housing part 2 protrudes again.
  • the round recess 6 on the inside of the housing is expanded by a rectangular opening 7, into which the side strips 22 of the sleeve 20 protrude when the connector is installed.
  • a raised ring contour 9, which is adapted to the two openings 6, 7, is provided, which ensures an increase in the air and creepage distances as well as a twist-proof assembly of the two housing parts 2, 3.
  • a wedge element 40 is provided, which in one variant is already connected to the housing part 3 by means of a thin material connection - a web 41 - during manufacture inside the housing part, which, as explained later, serves as a predetermined breaking point. In another variant, a separate wedge element is provided, which is only inserted into the housing part 3 during assembly.
  • a through opening is provided which has different individual openings with different functions.
  • the opening 33 is provided, which is followed by an opening formed by lamellae 32 and protrudes into an enlarged recess 31, which in turn is provided for receiving the sleeve 20 and the ring contour 9 of the housing part 2.
  • the wedge element 40 in a greatly enlarged illustration.
  • the wedge element essentially has two strip elements rotated by 90 ° with respect to one another, which consist of a wedge 42 with a wedge tip 43, and the staggered guide part 44.
  • a narrow, circumferential web 41 is shown, which in a one-piece variant, housing part 3 and wedge element are produced in one injection molding process, which holds the wedge element within the housing part 3.
  • a locking lug 46 is provided on the narrow sides of the guide part, by means of which the wedge element is held captively within the guide 35 of the housing part 3.
  • the narrow side of the wedge 42 facing the sleeve 20 has a bevel 47.
  • An angled end piece 45 is formed on the guide part 44, with which the wedge element can be pulled out or pushed in from the housing part 3, a groove 48 being provided for the use of a screwdriver on the outward-facing side of the end piece.
  • the functioning of the wedge element 40 is as follows: ready for assembly
  • the state of the connecting element is the wedge element in one of the design variants with a predetermined breaking point designed as a web 41 inside of the connection-side housing part 3 held.
  • the end piece closes 45 of the wedge element in one plane with the outer wall of the housing part 3 from.
  • the pin contact 10 is within the attached sleeve 20 of the assembled housing 1 inserted.
  • the wedge 42 between the wedge opening 24 of the sleeve 20 and expands it.
  • the side of the wedge 42 facing the sleeve is matched to the inside diameter of the sleeve 20, so that when the strands are inserted, none of the individual wires can be inserted between the opened side strips 22 on the sleeve.
  • the strands of an electrical conductor can simply be inserted into the annular cavity between the sawtooth contour 14 of the connection end 13 of the pin contact and the sleeve 20.
  • the wedge element 40 is removed from the housing part 3 by pulling on the angled end piece 45.
  • a simple tool e.g. B.
  • a separately manufactured wedge element 40 which differs as far as possible from the housing part 3, is merely inserted into the guide 35 and held captively by means of the locking lugs 46.
  • connection element consisting of the elements of the pin contact 10, the sleeve 20 and the wedge element 40, wherein also the purely "digital behavior" of the system becomes clear, which consists in that the wedge 42 with its wedge tip 43 either between the side strips 22 of the longitudinal slot 21 can be inserted and the sleeve expands or the spring-loaded sleeve returns to its original state as soon as the wedge tip reaches the wedge opening 24 of the sleeve.
  • 5a and 5b each show a single connection element in a sectional view through the assembled housing 1, consisting of the housing parts 2, 3. It can be seen how the pin contact 10 is guided with the sleeve 20 placed over it in the two housing parts 2, 3, the lamellae 32 abutting the funnel opening 32 of the sleeve with a narrower diameter.
  • This has the advantage that the strands of an electrical conductor are first focused by means of the lamellae, then meet the conical connection end 13 of the pin contact and are then divided around the cone tip into the space between the sleeve and the connection end.
  • 5a shows how the wedge 42 is inserted between the side strips 22 of the sleeve and thus increases the sleeve diameter.
  • FIG. 6 shows a sleeve 50 for a varied connection element, which works according to the same principle, but with its external design is matched to an already existing plug system, so that this connection element can be easily and alternatively used for a socket or pin contact that is already in use can be used.
  • the sleeve 50 with a front end 51 and a rear end 52 with a larger diameter has two perpendicularly extending slots 53 which extend as far as the rear end 52, so that four resilient segments 54 are formed which are formed by the rear end 52 be held together.
  • the middle section between the front and rear ends has a smaller diameter than the front end 51.
  • the part of the front end 51 projecting into the sleeve interior is provided with a hook-shaped projection 55.
  • FIG. 7 shows the sleeve 50 with a varied connection end 13 'of the pin contact 10 as a section, the sleeve being shown in the opened assembly state.
  • the sleeve is opened by a mechanical deflection, which is provided on the connection end 13 'and is formed by an axially, parallel section 17 which extends with a rounding to the constriction 19.
  • the diameter of the constriction corresponds to the inside diameter of the hook-shaped projection 55 of the front end 51 of the sleeve, while the section 17 has a larger diameter.
  • the sleeve 50 is held under the tension of the four resilient segments 54 on the section 17 and is displaceable up to the locking ring 18.
  • An electrical conductor with a large number of strands can be inserted into the free space created between the sleeve 50 and the sawtooth contour 14 up to the stop 16. After inserting the strands, the sleeve is pushed axially in the same direction - as the strands already - until the hook-shaped projection 55 slides into the constriction 19, the sleeve cross section narrowing again and the strands between the sawtooth contour 14 and the inner wall of the sleeve 50 are pressed.
  • a sleeve 20 ' which is rolled and resiliently rolled from resilient sheet metal material is not provided with a side strip 22, which extends over the entire length of the sleeve, as in FIG. 4 and which is bent outwards from the sleeve jacket, but in which only a simply bent wedge opening 24 'is provided, which has a short axially aligned side strip 22'.
  • the sleeve has an overlap, in which the outer lateral surface 26 of the sleeve projects tangentially beyond the edge of the inner lateral surface 25, the edge resting closely on the outer lateral surface.
  • a wedge element e.g. B. the blade 40 'of a screwdriver in the Wedge opening 24 'inserted up to the side stiffener 22' increases the diameter of the sleeve, the edge of the inner surface 25 slides along the outer lateral surface 26, so that the Longitudinal slot between the two lateral surfaces always for the in the sleeve inserted stranded wire is blocked.
