Definitions

  • the invention relates to a connector arrangement for a multi-core cable according to the preamble of claim 1.
  • Such a connector arrangement is known from EP-A3-0 189 857.
  • the contact elements are inserted axially into the receiving channels of the plug core and are held therein by barbs, which prevent a movement direction of the contact elements opposite to the insertion movement.
  • a comb is inserted through radial openings at the rear line-side end of the plug part, which engages behind a seal pushed onto the contact elements and represents a second locking of the contact elements.
  • Such a connector arrangement is difficult to assemble, especially if it is a miniature connector, since the cable wires for the axial insertion of the contact elements into the receiving channels must have a free length that allows maneuvering, which must later be accommodated in the connector housing.
  • the shielding can only contact after plugging it together, which is very complex and makes automatic connector assembly impossible.
  • a plug arrangement according to the prior art is difficult to disassemble, for example for repair purposes, since the contact elements do not damage the plug core or the contact element itself difficult or impossible to remove from the plug part.
  • each individual contact element can only be inserted into the receiving channels in a very specific position and locked in these. The assembly of such a connector arrangement is thus complex and the disassembly of the individual connector parts is complicated or not possible at all.
  • the coupling is made more difficult by the fact that the plug parts must have an aligned rotational position with respect to one another at the start of their insertion movement.
  • the invention has for its object to provide a connector assembly of the type mentioned, which is easier to assemble and easier to use.
  • the contact or counter-contact elements ie Plug or socket elements
  • the respective insertion of the contact elements into the recess can be carried out particularly easily and quickly, since the contact elements do not have to be arranged in a specific position in the recesses.
  • a rotation of the contact elements in the direction of their longitudinal axis is therefore not necessary to insert or press the contact elements into the core body. This simplifies both the manufacture and the disassembly of the connector arrangement.
  • each recess With the help of the radially outwardly projecting projections narrowing each recess, a simple possibility is created to secure the contact elements against axial movement.
  • the pin contacts attached to the free end of the contact elements for example with the aid of crimping technology, enable fully automatic attachment and thus mechanical production.
  • a recess corresponding to the projection can be formed particularly easily on the contact element if the pin contacts are arranged at a distance from the insulating jacket end of the individual wires of the cable. With the Striking the pin contacts therefore creates the recess which is advantageous for an axial hold.
  • the front section of the plug core facing the opening of the first housing part protrudes axially slightly beyond the pin contacts in the assembled state of the first plug part, since the mating contact elements can thus initially be inserted particularly easily axially into the plug core without the pin contacts having to be gripped around. This allows mutual fixing of the plug cores with very little effort in the axial direction, which additionally simplifies the handling of the plug arrangement.
  • the holding claws with a partially cylindrical cross section and the free end of the holding claws as a clamping element, since the inner surface of each holding claw is thus well adapted to the cylindrical outer surface of the cable and can be supported uniformly on the latter.
  • the clamping element also enables the cable end to be clamped firmly between, for example, two diametrically opposite holding claws.
  • the clamping process can be carried out by spring pretensioning of the individual brackets or by an external force. The cable end is thus securely connected to the plug part at all times. Tearing off the cable is almost impossible during the assembled state.
  • the clamping action of the clamping element is further supported by the fact that the clamping elements have a screw thread on their outer surface and that each clamping element has on its inner surface a radially inwardly projecting projection, one of which is towards the free end of each Holding claw connects inclined clamping surface.
  • the screw thread enables a permanent clamping effect by simply, releasably fixing the clamping elements on the cable section. With the help of the projection, a good clamping effect is achieved even with low clamping forces, since the projection presses firmly into the cable end.
  • the projection also ensures, in connection with the inclined clamping surface, a clamping pressure which is limited in area and thus increased, since this increases with a constant force but a reduced area.
  • each thread of the screw thread located on the clamping element with a rising, inclined towards the guide ring and an adjoining radially falling thread flank not only enables screwing but also a fully mechanically latching of an element that presses the free ends of the holding claws towards each other .
  • This feature also simplifies the manufacture of a well-supported connector part.
  • the clamping ring By means of the clamping ring provided on the end section of the cable, damage to the cable due to excessive pressing forces acting on the clamping element of each holding claw is effectively prevented.
  • the clamping ring is attached to the folded back shield of the cable, so that the clamping ring, the fixed supporting claws supported thereon, the guide ring and the first housing part in the sense of a double action also ensure an additional ground connection.
  • the shielding can also be pulled back and the clamping ring applied fully automatically. With the additional ground connection to the housing part, an uninterrupted electrical shielding can be achieved.
  • each holding claw It is also favorable to provide the clamping ring with a circumferential, radially outwardly extending stop against which the free end of each holding claw rests in an axially supported manner in the installed state.
  • the clamping element of each holding claw is not only held firmly on the clamping ring in the radial direction, but also effectively prevents axial displacement of the clamping ring seated on the cable end in the direction of the guide ring.
  • the plug part is assembled particularly simply by plugging the core body onto the holding rivet connected to the clamping ring and extending axially away from the end section of the cable, the free end of which is arranged in the central longitudinal axis of the plug part.
  • the core body attached to the holding rivet can also be inserted fully mechanically into the plug core and the guide ring.
  • the holding rivet which can also be designed as a blind rivet, can be easily expanded, so that the core body and plug core form a unit in which the contact elements are held.
  • the plug core of the first plug part is secured against undesired rotation in relation to the first housing part when the Latching projection engages in a counter-latch projecting radially inward in the inner wall of the first housing part.
  • the connector part and housing part can therefore only be rotated if the locking projection is also moved out of the counter-locking.
  • the locking spring thus enables simple and inexpensive fixing of the plug part in the housing part.
  • the part of the holding claws designed as a clamping element and the clamping ring located between them protrude axially at least partially over the first housing part in the assembled state of the first plug part, and an end cap is screwed or snapped onto the screw thread of the clamping elements.
  • the housing part is axially fixed to the plug core and via the clamping ring with the cable, on the other hand, an uninterrupted earth connection and thus electrical shielding is ensured via the clamping ring, the end cap, the clamping bracket and the housing part.
  • the end cap can also be mechanically snapped onto the clamping element, which further rationalizes the manufacture of the entire plug part.
  • the end cap also serves to support the free end of each holding claw axially firmly on the stop of the clamping ring which extends radially outward.
  • an axial play is provided between the first housing part and the end cap seated on the clamping element and the clamping ring in the locking position of the locking projection and counter-locking, so that the housing part releases the engagement of the locking projection and counter-locking on the plug core for mutual coupling of the Plug parts can be rotated freely can.
  • the axial play preferably corresponds to at least the gripping depth of the locking projection and counter-latch, so that there is almost no axial play between the housing part and the end cap when in their disengaged position.
  • Electrical cables are usually provided with a shield, with a ground connection from the shield to the plug part.
  • a shield with a ground connection from the shield to the plug part.
  • at least the clamping ring, the holding claws, the end cap and the first and second housing parts consist of an electrically conductive material or have a conductive coating.
  • the construction of the plug arrangement ensures an uninterrupted ground connection. Additional parts are not required to form the ground connection.
  • the respective plug parts are arranged such that they can be plugged into one another.
  • Completely shaped straightening and / or guiding elements are dispensed with, so that the manufacturing costs are reduced without having to do without quick and uncomplicated handling of the plug arrangement. Mutual coupling of the connector parts can therefore be carried out without special attention.
  • a coupling process can be carried out particularly quickly if each guide rib of the screw thread is part of a 60 ° bayonet screw closure and has an axially extending stop at its rear end. This makes it possible to align the plug core of the first plug part before coupling the plug parts in the first housing part in such a way that the plug cores are closed
  • the beginning of the engagement between the guide rib and the guide groove are pluggable to each other. Since the guide ribs are present in any case, it means little manufacturing effort to design each guide rib in the axial direction as a stop. It is particularly advantageous to design the width of the guide rib in the area of the bayonet screw closure and in the area of the stop in an identical manner. With the help of these features, the handling, namely the coupling of the plug arrangement, is therefore simplified without significantly increasing the production costs.
  • a particularly effective arrangement is possible if the plug core of the first plug part is arranged between the guide ribs and the guide ring in the region of the stops and the plug core and guide ring are integrally connected to one another. As a result, the latter can be produced in the same process step, which further reduces the number of parts required.
  • the guide ring has a cylindrical outer surface with two diametrically opposite recesses, the length and depth of which is designed such that the plug core with its guide ring can be pushed axially past the guide ribs into the opening of the first housing part.
  • the connector arrangement provides that in the ready position of the first connector part the connector core is inserted into the first housing part without twisting and one edge of the recesses abuts one side of the stop of each guide rib.
  • the first housing part in the closed position of the first plug part, the first housing part is rotated by approximately 60 ° with respect to the first plug part in comparison to the ready position, the other edge of the cutouts resting on the other side of the stop of each guide rib.
  • the cutouts thus allow a stop for fixing the housing part in relation to the plug core in a simple manner. This measure considerably simplifies the handling of the connector arrangement.
  • the second housing part axially projects slightly beyond the front end of the plug core, which faces the opening of the housing part, or the mating contact elements, in order to effectively protect the mating contact elements of the plug core against damage.
  • the respective ends of the plug cores or mating contact elements facing the opening of the housing parts do not rub against each other when the first housing part is rotated on the second housing part.
  • each guide groove with two guide surfaces, of which the second guide surface in the direction of rotation is undercut to the front edge of the second housing part in such a way that the entire guide rib can be axially displaced into the guide groove before the screwing movement.
  • This axial feed movement indicates to the user that the two connector parts, in particular their connector cores, are aligned with one another and are at least partially already inserted into one another.
  • Mutual coupling of the two connector parts is thus possible simply and quickly by sliding the front sections of the guide ribs on the tubular cross-sectional area up to the respective guide groove and by at least partially inserting the two connector parts into one another by means of an axial feed movement before the screwing movement and then are completely pressed into each other by the 60 ° screw connection, so that the contact elements of the first plug part are connected to the mating contact elements of the second plug part.
  • Mutual coupling of the connector parts is therefore simple and inexpensive to carry out.

  • the second connector part 3 has a cap 122, in which the second housing part 13 is inserted axially projecting, so that it forms a body socket with it. But it is also possible to design the second connector part as a built-in socket or as a cable coupling.
  • a coding 123, 124 is provided on the upper side of the plug cores 4, 12 according to FIGS. 1 and 4. However, it is also possible to produce the connector arrangement 1 without such coding.
  • a triangular marking 125, 126 is attached to the front edge of the first housing part 7 and the cap 122, which marks the different positions of the first housing part 7 with respect to the plug core 4 and the first housing part 7 with respect to indicates throw 122.
  • the left mark 125 on the upper side of the first housing part while in the closed position after a 60 ° right turn of the first connector part 2, the right mark 125 stands vertically above the longitudinal axis 24 and thus opposite the mark 126.
  • the assembly of the first connector part is described in more detail below.
  • the shield 27 of the cable is pushed back and the clamping ring 34 with its front section 35, rear section 36, its holding arm 43 and its front end 44 carrying the holding rivet 41 is pressed firmly onto the folded back shield and the cable end.
  • the individual cable cores 8 protrude in the axial direction up to approximately the height of the hollow rivet section 45.
  • the contact elements 6 are then struck with their cable sleeves 32 to form a recess 33, so that the pin contacts 51 extend approximately to the level of the hollow rivet section 46.
  • the inner core body 15 is pushed with the aid of its through opening 25 onto the free end 42 of the holding rivet 41 up to the hollow rivet section 45 and onto the front end 44 of the holding arm 43.
  • the contact elements 6 are inserted or pressed into the channel-shaped recesses 17 of the inner core body 15 from the outside in such a way that the pin contacts 51 protrude beyond the core body and each recess 33 is arranged approximately in the region of the projection 20 provided in each recess (cf. 3).
  • the holding rivet 41 can be expanded with the aid of the expansion pin 50 so that the inner core body 15 is firmly connected to the plug core 4 and the pin contacts 51 extend in the receiving channels 5.
  • the projections 72, 73 of the clamping elements 62, 63 are arranged at the level of the recessed edge 37 of the front section 35 of the clamping ring 34 (cf. dashed illustration in FIG. 2).
  • the embossing head When the expansion pin 50 is pulled through the hollow rivet sections 45, 46, the embossing head initially slides to the region of smaller diameter 47. This is expanded in such a way that the inner core body 15 is already firmly connected to the clamping ring 34. When the expansion pin 50 is pulled further, the hollow rivet section 46 is then expanded in such a way that the plug core 4 sits firmly on it. When the embossing head emerges from the hollow rivet section 46, its end is flared by the flow of material.
  • the first housing part 7 is advanced axially via the screw thread 66, 67 of the clamping elements 62, 63 in the direction of the front section 53 of the plug core 4 until the latching projections 86, 87 engage in the counter latches 89 provided in the lining 88.
  • the end cap 93 is then screwed or snapped onto the screw thread 66, 67 protruding beyond the first housing part 7 with its internal thread.
  • the projections 72, 73 of the clamping elements 62, 63 are radially pressed behind the recessed edge 37 behind the clamping ring 34, the free ends 60, 61 of the holding claws 57, 58 being held axially on the stop 40 of the clamping ring 34.
  • the first connector part 2 is thus completely assembled and is in the standby position, in which the edges 110, 111 of the cutout 107, 108 bear against a side 112 of the stop 105.
  • the plug core 4 and the first housing part 7 are in the ready position, ie the plug cores 4, 12 are aligned with one another at the beginning of the engagement between the guide rib 100 and the guide groove 102.
  • the first plug part 2 is now moved in the direction of the second plug part 3 until the front section 103 of each guide rib 100 bears against the tubular cross-sectional area 116 of the second housing part 13.
  • the first housing part 7 can now be rotated together with the plug core 4 due to the engagement of the latching projections 86, 87 with the corresponding counter-latches 89, the front section 103 of each guide rib 100 sliding on the cross-sectional area 116 of the front edge 120.
  • the subsequent 60 ° screw movement of the first housing part 7 on the second housing part 13 causes the guide ribs 100 to slide along the guide surfaces 118 and generates an axial feed movement, by means of which the mating contact elements 11 are pushed completely onto the pin contacts 51.
  • the connector arrangement is in the closed position, in which the first housing part 7 is rotated clockwise by 60 ° compared to the ready position and the other edge 113 of the recess 107, 108 interacts with the other side 114 of the stop 105.
