Definitions

  • the invention relates to a socket for a multi-pole, in particular for a 13-pin connector for the electrical connection of motor vehicle trailers, with a socket housing in which a contact-carrying contact carrier is received, the contacts being a conductor connection part via which they are connected to an electrical conductor and have a sleeve part for receiving contact pins of a plug, the contact carrier having a predetermined geometric hole pattern corresponding to the number of poles, the holes being provided for at least partially receiving the contacts.
  • the invention also relates to a multi-core conductor strand for installation in a socket for a multi-pole, in particular for a 13-pole plug connection for the electrical connection of motor vehicles, each conductor of the conductor strand being connected to a conductor connection part of a contact, the conductor connection part being opposite to the connection point the conductor passes into a sleeve part for receiving contact pins of a plug.
  • a 13-pin socket for a plug connection for the electrical connection of motor vehicle trailers is known, for example, from the draft of the DIN standard 72 570 from March 1987. Furthermore, multi-core cable harnesses for installation in such sockets are known.
  • Such a box consists of an essentially hollow box housing which is provided with a lid.
  • the lid can be opened against the force of a spring and closes automatically due to the force of this spring.
  • a contact carrier is accommodated in the socket housing, which carries 13 contacts, for example in the case of a 13-pin socket.
  • the contact carrier can be inserted into the socket housing from the bottom end and can be pulled out of the socket housing against this direction.
  • the contact carrier itself is designed in two parts and in such a way that between the Both parts of the contacts can be made captive.
  • Such a box is mounted, for example, on the outside of a body of a motor vehicle in the area of the rear bumper.
  • a plug of a motor vehicle trailer can be inserted into the socket so that it is supplied with power by the motor vehicle.
  • the socket is connected to the dashboard of the motor vehicle or the power source via a multi-core, for example a 13-core cable harness.
  • a relatively thick conductor strand extends from such a multi-pole socket, which must be routed in cable channels in the body to the dashboard or to the power source.
  • Another problem is that there is a high possibility of incorrect connection due to the large number of cable wires when connecting to the socket. From a purely mathematical point of view, for example, it is possible to connect a 13-core conductor strand to a 13-pin socket in around 6.3 billion different ways. In order for the individual wires to be connected to the socket as flawlessly as possible, complex marking measures are necessary, which also require a specially trained person for the installation.
  • An assembly of the electrical supply in an assembly line production takes place in a relatively late phase of the assembly of an automobile, so that an assembly step, which has a very high error rate and also requires a relatively long time because of special attention during assembly, is a potential one Bottleneck in the assembly line system arises, which must be avoided by special measures, such as branching or stowage.
  • Known sockets are essentially designed as hollow bodies into which a contact carrier equipped with the conductors and contacts can be inserted from the bottom side.
  • the contact carrier sits exactly positioned in the socket designed as a hollow body, it has on its outer contour mounting features such as protruding spider-like legs or protruding lugs, which engage in corresponding inner grooves in the socket, so that such contact carriers have outer contour dimensions that are considerably larger than the outer contour of the Extend conductor line, and therefore no longer or very difficult to reach through cable ducts in motor vehicles. If curvatures or bends are even provided in the cable duct, there is a risk that the stiff and bulky contact carriers will tilt and can only be removed from the cable duct with force, possibly with destruction.
  • the multi-pole conductor strand as such does not completely fill the duct, so that it is possible at any time to pull other conductors into the duct to supply power consumers in the rear area of the motor vehicle. Examples of this are the lighting of the rear license plate, brake lights, rear fog lights or the like. If you look at a conductor channel that has just the diameter of the contact carrier, and the contact carrier is pushed through this channel before all other cables are laid, it becomes one later it is no longer possible to replace such a conductor strand without first removing the other conductors. This would mean that an exchange of the conductor strand leading to the rear box would inevitably involve an expansion of all the conductors leading into the rear area of the motor vehicle.
  • the object of the present invention is therefore to remedy this situation and to improve a socket or a multi-core conductor strand for installation in such a socket in such a way that simple assembly and, if appropriate, also disassembly is possible with the smallest possible space requirement in the vehicle body.
  • each contact is partially received in an opening of an elastically flexible, rubber-like element.
  • this component can be bent or compressed, so that it can be pushed through narrow channels or bottlenecks which have a smaller diameter than the elastic element in the non-compressed or unbent state.
  • the contacts are accommodated in the element in such a way that it cannot reach over the sleeve parts, the contacts are thus held captive in this direction.
  • the contacts are fixed relative to one another by being received in the element, ie if they are mounted exactly positioned beforehand, the contacts in the element can no longer be displaced relative to one another. In other words, if, for example, the rubber-like element is held in the hand, the contacts, if the conductors are pulled, cannot be pulled off the flexible element.
  • the contacts can be pushed out of the element in the opposite direction, pulling the conductor through the corresponding opening in the element. Since the conductors for laying in a motor vehicle are several meters long, with careful handling there is no danger that a contact together with its attached conductor will be pulled out completely. Appropriate precautionary measures are of course provided, which can simply consist in the corresponding conductor at the opposite end also being provided with a contact which is provided for connection to the dashboard, this contact having a diameter such that the cable contacts this contact cannot be pulled through the flexible element.
  • the flexible element according to the invention can, for example, be easily equipped by pushing a conductor through the opening and screwing the pushed-through piece to the contact, is soldered, crimped or the like.
  • each contact including the attached conductor, is seen in the direction from the conductor connection part to the sleeve part, can be removed from the element, but sits immovably in the element in the opposite direction, and the element, including the contacts partially accommodated therein, is detachably connected to a contact carrier.
  • these sleeve parts with attached cable can be removed from the flexible element, it is advantageously possible to pull off some or all of the sleeve parts from the flexible element, so that they may be offset in axial length, closely together nestled through the channel in the body.
  • the flexible element can then be squeezed or possibly in cross section direction of the cable duct inclined, be guided through this. After the flexible element and the corresponding contacts have emerged through the rear opening of the cable duct and out of the body, the sleeve parts need only be pulled back to the flexible element by means of the cables and then protrude exactly from the latter.
  • the assembly of flexible element and contact carrier can be removed from the socket, the contact carrier can be removed from the flexible element, so that the contacts are freely accessible.
  • the critical point namely the connection between the conductor and the conductor connection part of the contact, which is particularly susceptible to corrosion
  • the corresponding contact with the attached conductor only needs to be slightly removed from the flexible element, so that a visual inspection can be carried out easily.
  • the contacts with their conductor connection part are positively received in the openings of the flexible element.
  • This measure has the advantage that the contacts are firmly and securely received in the element via the positive connection, so that the contacts do not come into contact with one another before assembly or during transport or storage, or the sensitive sleeve parts do not touch one another.
  • the exact fit also facilitates the assembly process of the flexible element and contact part, i.e. by pulling the conductors, the contacts can be pulled into the flexible element while sitting tightly.
  • the contacts in the area of the sleeve part have a larger diameter than in the area of the conductor connection part.
  • This measure has the advantage that a particularly structurally simple measure ensures that after a conductor has been pushed through the corresponding opening of the flexible element and its pushed outer end is connected to a sleeve, this contact in the opposite direction no longer from Element can be deducted.
  • the flexible element is constructed as an element releasably composed of several segments, preferably of two semicircular disk segments.
  • the preassembled conductor strand can be divided into individual thinner sub-strands for assembly.
  • a 13-pin socket according to the previously mentioned draft for DIN standard 72 570 has an exact prescribed hole pattern with an approximately circular outer contour.
  • the conductor strand can be divided into two partial strands approximately half as thin as the entire strand, which are successively pulled through a relatively thin conduit can.
  • the two disk segments are reassembled into a circular segment, this process likewise being clearly determined and being able to be carried out without a source of error.
  • the sleeve parts of the contacts on the one hand only provide the cables on the other hand, so that incorrect assembly is impossible according to human judgment.
  • the contact carrier is designed as a rigid component and is connected to the elastic element in such a way that the contacts are axially immovable to the contact carrier.
  • This measure has the advantage that, after the flexible element and the contact carrier have been put together, the contacts of an insertion movement of the contact pins of the plug into the sleeve parts of the contacts cannot dodge axially.
  • the contact carrier is formed in a contact area of the flexible element as a perforated disk-like plate, through the opening of which the sleeve parts can be slid appropriately, the contacts between the section and the element received a sleeve part projecting from this have a neck with a smaller diameter, the axial length of which corresponds at least to the material thickness of the plate, the hole pattern of the plate and approximately disc-shaped flexible element being offset laterally by the difference in the radii of the sleeve part and neck when the contact carrier and element are joined together.
  • This measure has the advantage that an engagement between the contact and the contact carrier is present in the contact carrier by engagement of the plate-shaped part in the space recessed by the smaller diameter neck such that if a force is exerted on the sleeve part by inserting a contact pin of a plug, this force is transmitted to the rigid contact carrier or to its plate part. Axial deflection of the sleeve parts when inserting a plug is then no longer possible. To release the contacts from their engagement with the plate-shaped part of the contact carrier, they only have to be shifted laterally by the amount by which the plate or the corresponding section in protrudes the smaller diameter neck.
  • This engagement is in the range of half to 1 mm, so that a slight pushing aside, which is possible due to the elasticity of the elastic element, the larger diameter sleeve parts can be brought back into coaxial alignment with the holes or openings in the plate, so that these can then be moved away from the contact carrier.
  • the axial length of the neck corresponds to a cylindrical section of a bore in the plate, and the neck merges into a larger diameter area on the side of the conductor connection part.
  • This measure has the advantage that an annular groove is provided on the contact in the area between the conductor connection part and the sleeve part, into which a sickle-like area of the plate-shaped part of the contact carrier, which surrounds the opening in the contact carrier, can enter. This ensures a consistently safe engagement regardless of the rotational position of the contact during assembly. Because the length of the neck corresponds exactly to the material thickness or a cylindrical section of a hole in the plate, a play-free, axially immovable fit is achieved. As a result, a contact sits axially firmly in the contact carrier or in the socket, at best, with a possible lateral play or a play required on the basis of standard regulations.
  • the larger-diameter section of the contact on the side of the conductor connection part is formed by an outer ring flange, the Outer diameter corresponds to the inner diameter of the opening in the plate of the contact carrier.
  • This measure has the advantage that in a configuration of a contact carrier which has only the shape of a plate, ie that when the flexible element and contact carrier are joined together, the sleeve parts extend away from the contact carrier, a single contact can be removed from this assembly without this must be solved.
  • By pressing laterally in the appropriate direction on the ring flange area of the contact to be replaced it can be brought into such a position that it extends coaxially with the opening in the plate of the contact carrier, so that it is then guided exactly, ie without relying on it surrounding contacts or their sleeve parts inclined, can be removed from the contact carrier.
  • This contact can then be checked and, if necessary, renewed, and then inserted into the outer ring flange from the side opposite the one on which the element rests on the contact carrier.
  • the flexible element must then be aligned again by lateral displacement in such a way that its opening runs at least coaxially with the corresponding opening in the contact carrier or its plate until the outer ring flange has been pushed through the contact carrier.
  • the outer ring flange is embedded in a corresponding recess in the elastic element.
  • This measure has the advantage that a contact in the area of its conductor connection part and in the area of the ring flange is positively secured against tilting in the flexible element.
  • the flexible element lies flat against the contact carrier so that no moisture or dirt can pass through the contact carrier from the cover side of the socket.
  • the individual holes of the hole pattern of the disc-shaped elastic element are seen from the center of the disc, each radially offset by a difference in the radius of the sleeve part and neck from the hole pattern of the plate of the contact carrier.
  • This measure has the advantage that, for example, in the case of a 13-pin socket in which 9 poles are arranged approximately in a circle and surround the 4 remaining poles in the center, these are loosened by approximately the same amount when loosening the elastic element and contact carrier by radial displacement to the center can be brought into the position in which they can be removed from the contact carrier.
  • This can be done quite simply, for example, by encircling the entire sleeve parts with one hand and by pressing them all together at about the same time in the radial direction be moved.
  • these outer nine contacts can already be pulled off to the extent that they remain in their coaxial orientation due to the elasticity of the material.
  • the inner four sleeve parts can then be pressed radially inwards, so that all 13 sleeve parts are then coaxially received in the openings of the plate of the contact carrier, and all of them can then be removed from the contact carrier together with the flexible element.
  • the hole pattern of the disc-shaped element and the hole pattern of the plate in the contact carrier are of the same geometric arrangement, and the disc-shaped flexible element is laterally offset with the contact carrier after pushing the sleeve parts through the openings in the plate.
  • This measure has the advantage that the sleeve parts can be easily pushed through the openings of the contact carrier without the use of force by an identical hole pattern of disc-shaped element and plate in the contact carrier. After pushing through, the entire flexible element is displaced relative to the contact carrier by a certain amount, which in turn corresponds to the difference in the radii of the sleeve part and neck. Appropriate precautionary measures must then be taken to ensure that the sleeve part remains in this position.
  • this last-mentioned measure is achieved in that the contact carrier is designed as a hollow cylindrical body which, on the side with which it is inserted into the socket housing, is closed with the plate, the elastic disc-shaped element being offset with its hole pattern on the lower side of the plate facing the cavity under lateral tension.
  • This measure has the advantage that the hole pattern in the disc-shaped, flexible element, if this is inserted into the cavity, is laterally offset from the hole pattern of the plate in the cavity body.
  • the flexible element When inserting the disc-shaped flexible element into the cylindrical cavity of the contact carrier, the flexible element must be bent slightly in a crescent-shaped area that encompasses approximately half the circumference, so that the sleeve parts are coaxially aligned with the openings in the plate and can be easily pushed through them . If this is achieved, the pressure or the elasticity of the elastic element ensures that it is laterally displaced, this evasion again being possible due to the smaller diameter neck in the contacts.
  • the disk-shaped flexible element lies coaxially flush with the disk-shaped underside of the plate of the contact carrier, but the contacts are laterally offset by the amount of the difference between the radius of the sleeve parts and the radius of the neck, so that they sit axially immovably in the contact carrier.
  • the contact carrier is designed as a cylindrical body with through openings for receiving the entire sleeve parts of the contacts, a disc-shaped section of the contact carrier being displaceable laterally after insertion of the sleeve parts in such a way that it engages in the neck of the contacts, so that the contacts carried by the element are axially immovably received in the contact carrier.
  • This measure has the advantage that contact carriers can be used which accommodate the entire sleeve parts.
  • the laterally displaceable, disc-shaped section of the contact carrier is displaced during the assembly of the contact carrier and flexible element in such a way that continuous, aligned openings in the contact carrier are released.
  • the flexible element with the protruding contacts then only needs to be pushed into these openings as far as it will go.
  • the disc-shaped section of the contact carrier is moved so far that it engages again in the shape of a sickle in the neck of the contacts.
  • the contacts then sit immovably in the contact carrier.
  • the entire assembly can then be pushed into the socket as usual.
  • Such a contact carrier can then also have the spider-like legs known per se for support in the socket, since it is only equipped with the contacts after the conductor strand with the elastic element has been pulled through the conductor channel of the motor vehicle.
  • the disk-shaped section of the contact carrier then only has to be displaced again to such an extent that it emerges from the annular recess in the neck and releases the sleeve parts for removal.
  • a socket 10 shown in FIGS. 1 and 2 has a socket housing 12 which is provided with a cover 14.

  • the element 70 is to be removed from the contact carrier 84 after both of these have previously been removed from the contact-receiving part 20 ', the element 70 only has to be packed by hand from the underside in the region of the tubular projections 76 and in the representation of FIG previously mentioned offset can be shifted to the right.
  • An outer right flap 79 of the element 70 is squeezed against the inner wall of the hollow cylindrical region of the contact carrier 30 ', this being possible due to the elasticity of the material of the element 70.
  • the contact carrier 84 is designed as a solid cylindrical body 86 which extends in such an axial length that it can accommodate the entire sleeve parts 82 of contacts 72.
  • the cylindrical body 86 merges into a base part 85 via a disk-shaped section 87, which can be displaced horizontally in the illustration in FIG. 4.
  • the foot part 85 delimits a hollow cylindrical interior, in which a flexible element 70 is received, which is received flush in the contact carrier 84 and thereby abuts the underside of the disk-shaped section 87.
  • the disc-shaped portion 87 is in the blocking position, i.e., as previously described, it is displaced such that it lies against the neck 80 of the contacts 72.
  • the entire assembly of contact carrier 84 and element 70 is first removed from the interior of the socket. 4 is then shifted to the left, as is indicated by an arrow 88. The displacement takes place in such a way that the corresponding openings in the disk section 87 are coaxial with the openings in the cylindrical body 86 of the contact carrier 84, in which the sleeve parts 82 are received. In this position, the element 70 together with the contacts 72 accommodated therein can be removed from the contact carrier 84.
  • the contacts 72 are accommodated in the element 70 both in the area of the conductor connection part 74 and in the area of the ring flange 78, these are seated very firmly in the element 70 even after the element 70 has been removed from the contact carrier 84.
  • a flexible element 90 is shown, which is constructed from two semicircular segments 91 and 91 '.
  • the semicircular segment 91 has on its linear edge a projection 103 which is more than semicircular in cross section.
  • the semicircular segment 91 ' accordingly has a recess 104 in which the projection 103 can be received in a form-fitting manner.
  • composite semicircle segments 91 and 91 ' form a continuous round disc that cannot be separated from one another in the radial direction, but can only be pushed apart in the axial direction.
  • the semicircular segment 91 has six openings 93, through which conductors 95 extend (for the sake of clarity, only four conductors 95 are shown), which are connected on the opposite side to sleeve parts 96 of larger diameter.
  • the semicircle segment 91 ' is accordingly provided with 7 openings 93', through which corresponding conductors 95 'extend, which are provided on the opposite side, at the semicircular segment 91', the side facing the viewer, with sleeve parts 96 '(for the sake of clarity are here only three conductors 95 'shown).
  • the semicircular segment 91 is also provided with a recess 105, which is provided as an installation feature for angular insertion in the corresponding contact carrier.
  • the element 90 together with the contacts 92 is to be pushed through a channel 100.
  • the element 90 is divided into the two semicircle segments 91, 91 ', the semicircle segment 91 initially being able to be pushed through the channel 100.
  • the semi-circular segment 91 can be bent in a U-shape, as is indicated, for example, by the arrows 101 and 102.
  • the semicircular segment 91 After pushing the semicircular segment 91, the semicircular segment 91 'can be pushed through the channel 100. For this purpose, as indicated by an arrow 99 in FIG. 5, it must first be pivoted through 180 °.
  • the cable harness shown in FIG. 5 can of course be pulled out of the channel 100 again by pulling the conductors 95 in the opposite direction, ie towards the viewer, without the risk that the element 90 and the contacts 92 will come loose or that their relative position to one another is changed in a cross-sectional plane.
  • FIG. 6 shows how a flexible element 110, which is equipped with sleeve parts 116 or conductors 115, which are brought together in a cable grommet 114, can be passed through a channel 112.
  • the diameter of the element 110 is substantially larger than the inside diameter of the channel 112. Because of the flexible design, it is possible to push the element 110 through the channel 115 in such a bent state. By bending, the conductor connection parts not shown here tilt in the element 110, so that even when pushed, as shown in Fig. 6, they do not move relatively along the conductors 115 i.e. moved away from the sleeve parts 116.
