Definitions

  • the invention relates to a device for the mutual electrical contacting of electrical and / or electromechanical assemblies in a housing of an electrical device, such as a car radio, video or audio recorder and data terminal device, such as a printer, preferably at difficult to access contact points between these assemblies , each with a plug-in element on a first assembly and on a second assembly, the plug-in element of the first assembly being connected to components of the first assembly via flexible electrical lines, as well as a method for contacting assemblies by means of this device and a device according to the Process is made.
  • an electrical device such as a car radio, video or audio recorder and data terminal device, such as a printer
  • Such a device is known in car radio cassette players.
  • contact points which are difficult to access within the housing of an electrical device, however, there is the difficulty that contacting the difficult-to-reach places is time-consuming and labor-intensive. Contact is particularly difficult when in the event of subsequent repairs, the contact points in the hard-to-reach places have to be loosened and reconnected.
  • the electrical contacting in the inaccessible places has a relatively strong cost-increasing effect.
  • the plug element of the first assembly is arranged on a bracket extending into an easily accessible area of the housing and that this bracket is releasably clamped to a carrier of the first assembly, so that this plug element when pressed and the holder can be inserted into the plug-in element of the second assembly.
  • the carrier is provided with guides which run in the push-off direction, and that the holder has grooves which run over the guides when the holder is pushed onto the carrier. It is known per se from DE-OS 33 01 568 to connect two assemblies with plug parts, with guides ensuring an exact meeting of the plug parts.
  • the guides can be arranged on a frame.
  • the holder is provided with guides which run in the push-off direction, that the carrier has grooves and that the holder with its guides moves into the grooves when pushed onto the carrier.
  • the brackets can be brought into the specified positions in this way, and during subsequent repairs, the brackets can be pulled out of the contacts into the specified starting positions.
  • the grooves and the guides always work together in a suitable manner.
  • the holder pushed onto the carrier is releasably clamped or latched to the carrier.
  • the clamps or the catches ensure that the brackets are always held securely in the specified starting positions for depressing. This is also an advantage for later repairs because the raised brackets are not loose, but are held in place.
  • the guides and the grooves work together in the push-off direction over such a length that the holder is released from the carrier shortly after the push-off begins. Immediately after pressing the holder is released so that it has enough play to align with the plug element of the second assembly.
  • part of the holder is simultaneously designed as a handle for a tool and for manual handling.
  • a handle design is particularly easy to repair for repair purposes, but also makes the use of robots easier.
  • the housing of this plug-in element of one of the modules has an insertion funnel for the plug-in element of the other module.
  • This insertion funnel ensures for securely catching the plug element of the first assembly in the plug element of the second assembly. This makes it easier and easier to compensate for mutual tolerances between the modules in the housing.
  • the individual assemblies are first checked individually for their functionality before being joined together with other assemblies. This checking is carried out with test devices which are provided with appropriate contacts for the test.
  • the plug-in element of the first assembly is in a position in the clamped or latched holder in which it contacts the test device with contacts when the first assembly is placed on a test device. If the contacts of the test device are arranged in such a way that when the first assembly is placed on the test device with the brackets clamped or locked in the carriers, the test can be carried out quickly, and the plug-in elements of the first assembly need not be special Handling is connected to the plug contacts of the test device. A simple contact ensures that contacting is secure.
  • the holder has a strain relief edge for the flexible lines.
  • the flexible cable connections which are preferably in the form of ribbon cables, are thus fixed to the holder in such a way that they cannot be damaged when they are pulled off.
  • a method is used, which is characterized in that the first assembly is positioned in an intended position relative to the second assembly, that the holder, the plug element in an osition above the plug elements of the plug elements the second assembly has reached, is pushed in the direction of the plug-in element of the second assembly by the carrier, that the holder with the plug-in element is released from the carrier when the impression is taken, and that the plug-in element of the first assembly is caught on its free path of movement and introduced into the plug-in element of the second assembly becomes.
  • Such a method is particularly suitable for mass production and is extremely economical.
  • a device manufactured according to this method has the special feature that for the formation of an opening in the housing a wall of the housing is at least partially omitted, the carrier of the first assembly placing the handle on the holder for opening and the other assemblies in such a way that the handle is accessible and manageable from the outside through the opening.
  • the plug-in contacts between the modules are in an inaccessible place on the bottom of shaft-like depressions, the contacts can be made and released again without difficulty. This allows the modules to be built close to one another without these contacts leading to assembly problems.
  • An electrical device which can be a car radio, a video or audio recorder and a data terminal, but also another device, is shown in FIG. 1 using the example of a car radio. It is important that an electrical or electromechanical assembly is to be contacted with another or with other electrical or electromechanical assemblies, the contact points being located in areas of the device which are difficult to access.
  • a first assembly 2 is attached to the bottom of the housing and is the drive of a cassette player.
  • This drive which is described in DE-OS 33 12 136 (PHD 83-037), has a chassis 3, against which three key rods 4, 5, 6 are displaceable.
  • the key bars 4, 5, 6 reach through the front plate 7 of the housing 1 and can be operated from the outside by means of push buttons 4a, 5a, 6a.
  • the drive also has a motor 8 for driving winding mandrels 9 and has a magnetic head 10 with which a magnetic tape (not shown) arranged in a compact cassette 11 can be scanned.
  • a magnetic shaft 12, to which a pressure roller 13 can be pressed, is used to transport the magnetic tape (not shown).
  • the motor 8 also drives the audio shaft 12.
  • the compact cassette 11 can be inserted into an elevator 14 and lowered onto the winding mandrels 9 with the aid of the elevator.
  • the lift 14 is controlled with the aid of a lift lever 15, which can be seen in FIG. 2.
  • the lift lever 15 is controlled by means of a boom 16 which is actuated by the push rod 4.
  • a second module 17, a third module 18, a fourth module 19, a fifth module 20, a switch 21 and connecting parts 22 are provided within the housing 1.
  • Cable connections such as a cable connection 23 and a cable connection 24, extend between the individual components.
  • Shafts 25 and 26 are formed between the first module 2 and the other modules.
  • electrical contact connections are to be made with the first assembly 2.
  • the first assembly is mechanically fixed to the bottom of the housing 1. In this case, tolerances occur which make it impossible to connect the contacts of the first assembly 2 which are connected directly to the chassis 3 to the chassis 3. These tolerances occur because the two assemblies are connected to the housing 1 independently of one another and the assemblies themselves have tolerances independently of one another. These tolerances can add up and assume an order of magnitude such that the direct electrical contacting of contacts fixedly arranged on the assemblies is not possible for mass production.
  • the device is equipped with special devices for mutual electrical contact. These devices are designated in FIG. 1 by 27 for a first device and 28 for a second device. The first device is shown enlarged in FIG. 2 and the second device 28 is shown enlarged in FIG. 3, the electrical contacts not yet being made.
  • the device 27 has a carrier 29 which is fixedly connected to the chassis 3.
  • the carrier 29 can also be machined out of the sheet metal of the chassis.
  • the carrier 29 is located in the vicinity of the motor 8 and extends perpendicular to the second assembly 17.
  • This second assembly is a heavily populated electrical circuit board.
  • the carrier 29 has guides 30 which delimit two opposite edges of a hole 31 in the center of the carrier 29.
  • the guides 30 run essentially perpendicular to the second assembly 17.
  • the carrier 29 has two latching lugs 32 which, after the guides 30, point towards one another into the interior of the hole 31.
  • a holder 33 can be pushed onto the chassis 3 by the second assembly 17.
  • the holder 33 is preferably a plastic part and has two U-shaped grooves 34 which extend approximately parallel to the guides 30.
  • the grooves 34 are provided with troughs 35, into which the locking lugs 32 engage when the holder 33, as shown in FIG. 2, is fully inserted. If the holder 33, as shown in FIG. 2, is fully pushed in, then projecting clamping edges 36 provided on the base of the groove become jammed on the guides 30. Thus, the holder 33 in the fully inserted state according to FIG. 2 is clearly positioned and held on the carrier 29 .
  • the holder 33 is provided with a handle 37 on its upper edge region, which can be inserted by hand or by a device after later insertion the opening 1a is detectable.
  • a strain relief edge 38 is provided within the holder 33, over which a ribbon cable 39 is pulled.
  • a pull-through hole 40 is provided between the strain relief edge 38 and the handle 37, through which the ribbon cable 39 is looped.
  • the ribbon cable is brought up to a plug element 41, which is provided with plug pins 41a.
  • the plug element 41 is connected to the holder 33 via a clamp connection 42.
  • An insertion funnel 43 is provided on the second assembly 17 and clamps onto the second assembly 17 with the aid of clip lugs 44.
  • This insertion funnel comprises another plug element 45, in which plug sockets 45a are provided.
  • the plug sockets are connected via connecting wires 45b to lines of the second assembly 17, not shown.
  • the first assembly 2 can first be placed on a testing device which serves to check the functionality of the first assembly.
  • a testing device which serves to check the functionality of the first assembly.
  • the connector pins 41a arrive at contact sockets of the test device assigned to them.
  • the first assembly is inserted into the housing 1 and first mechanically connected to the housing 1 in a manner not shown.
  • the second assembly 17 has already been installed in the housing. Now becomes the first assembly inserted into the housing after the second assembly, then the plug element 41 arrives above the insertion funnel 43 placed deep in the shaft 25.
  • no contact is initially made.
  • the advantage of this design is not only the secure contacting at the bottom of the shaft 25 and the collection of the tolerances already mentioned.
  • the further advantage is that the holder 33 can be pulled up by hand by means of the handle 37 in the event of repairs, so that the contacting can be released without problems. When pulling up, the locking can be brought back again.
  • the guides 30 again serve for the reliable movement.
  • the narrowness of the shaft 25 is not a problem for the solution of the contacts.
  • the device 27 is used, for example, to contact the motor 8 so that the drive functions of the first module 2 can be controlled via the second module 17.
  • a second device 28 is provided, with which further contacting is possible.
  • This contacting serves for the electrical connection of the magnetic head 10 to the second assembly 17.
  • the function of the second device 28 essentially corresponds to that of the first device 27.
  • the device 28 has a carrier 46 which is fixedly connected to the chassis 3.
  • the carrier 46 has grooves 47 which lie opposite one another and face one another.
  • the grooves 47 are provided in the area of the groove base with troughs 48, into which latches 49 a holder 50 can snap.
  • the carrier consists of a rectangular frame 51.
  • a ribbon cable 52 is arranged on the holder 50 and is electrically contacted with plug-in tracks 53, which together with the holder 50 form a plug-in element 54. Edges 51b of the frame 51 form guides within the grooves 47.
  • an insertion funnel 55 is again provided, which clings to the second assembly 17 with a clamp connection 56.
  • the insertion funnel 55 essentially corresponds to the insertion funnel 43 according to FIG. 2.
  • a plug element 57 is provided in it, which has contact springs 58.
  • the plug element 54 can be brought into contact with the plug element 57 by moving the holder 50 down.
  • the funnel 55 compensates for tolerances between the assemblies. The operation corresponds completely to that of FIG. 2, and it can thus be carried out with the aid of the device 28 again both a test with the holder 50 pinned and a contact when the holder 50 is depressed, as well as a repair by subsequently lifting the holder 50 and moving it down again .
  • a plastic part is attached to the bracket 50, which has a stop 59 which extends parallel to the upper edge of the bracket 50 and projects beyond it on both sides, so that the bracket 50 is lifted out of the plug element 57 when the upper edge of the Carrier 46 abuts the stop 58.
  • a curved protective bracket 60 is provided on the plastic part and forms a protection for the flexible electrical ribbon cable 52.
  • the protective bracket 59 extends from the stop 59 to the vicinity of the plug-in tracks 53.
  • the protective bracket is clamped to the frame 51 by means of clamping jaws 61 and 62a, 62b.
  • the clamping jaws 61, 62a, 62b are molded onto the protective bracket 60.
