Definitions

  • the invention relates to a fixture device for connecting an electrical multi-core flat band cable to a multi-contact connector according to the preamble of claim 1.
  • a base plate has a fixed guide to receive a connector.
  • a clamping plate is actuable through a toggle clamp to hold the cable end against the base plate and within the connector received in the fixed guide.
  • the base plate moves in a slide to position the positioned connector and cable under a tool driven by a ram. After the base plate has slided along the guide rail assembly to a position against a stop, the ram is lowered. Thereafter, the base plate is moved out along the guide rail assembly, the toggle is released from the cable and the connected cable can be removed.
  • the connector can be moved into the connector location simply by shifting in the guide, and can be again shifted away from the connector location after the connection has been made, the flat band cable connected to the connector lifting the clamping plate and moving therebelow transversely of the cable support track when the connector is shifted out.
  • This moving to and fro can be performed much simpler and more rapidly, and is more apt to become automated than the complicated movements which are necessary to lay a connector into a depression and to remove it again from the depression.
  • the clamping plate operates automatically and need not be pivoted open and closed, nor clamped first and again released. There are no complicated movably supported structural parts provided to clamp the clamping plate fast.
  • the guide extends linearly normally of the cable support track. This will result in a still further simplification.
  • the clamping force with which the clamping plate is biased can be produced very simply in that the clamping plate has sufficient weight to generate the clamping force. Then, moreover the advantage is obtained that the clamping force is independent upon the level of the clamping plate above the cable support track.
  • clamping force can be, of course, generated also by spring force. This will result in the advantage that the device can be operated substantially independently of its position.
  • multi-contact connectors comprise a lower part provided with cutting contact elements, and an upper part which can be plugged together with the lower part, and can be pressed together from an open position in which an introduction opening for the cable is formed between the lower part and the upper part, into a closed position in which the cable is connected and the parts of the connector are securely interengaged.
  • the guide is designed for the insertion of the upper part and is arranged in a fixed position relative to the cable support track.
  • the Figures show a device for connecting an electrical multi-core flat band cable 1 (Fig. 2) to a multi-contact connector 3 (Figs. 2, 5 and 7), which in the usual manner comprises a lower part 7 provided with cutting contact elements 5, and an upper part 9 guided thereon.
  • a multi-contact connector 3 FIG. 2, 5 and 7
  • a connector location 15 is defined on the device. If the connector is arranged there, it is located in a receiving position suited for the connection with the cable 1, as illustrated in Fig. 5.
  • the device furthermore comprises a cable support track 17 on which the cable 1 to be connected can be shifted in the direction of the arrow 19 (Figs. 2, 5) into a ready position in an open connector being in the receiving position (Fig. 5).
  • the cable support track 17 has grooves 21 for slidingly guiding the longitudinal ridges 23 of the cable 1 which are formed by the cable cores (Figs. 2, 5).
  • the device furthermore comprises a clamping plate 25 which is movable relative to the cable support track 17 and in the illustrated embodiment also has grooves 27 in an arrangement corresponding to the grooves 21 of the cable support track 17.
  • an abutment which can be provided at the device or at the connector 3.
  • an abutment 29 is provided at the device.
  • a straight guide 31 leading to the connector location 15 is provided, in which an open connector 3 to be connected can be advanced into the receiving position, i.e. into the connector location 15.
  • the clamping plate 25 is supported to be movable parallel with itself in a direction normally of the cable support track 17, i.e. normally of the advancing direction 19 of the cable 1 (Figs. 2, 5).
  • the clamping plate 25 is biased towards the cable support track 17 and forms at its front surface 33 which faces away from the connector location 15 an insertion hopper 35 with the cable support track 17.
  • the clamping plate 25 is supported only unilaterally and when lifted permits that the cable which is arranged between the clamping plate and the cable support track 17 is shifted inwards and outwards transversely of the cable support track 17, i.e. in the illustrated embodiment in the direction of the guide 31, whereby the completely connected connector can be removed from the device simply by moving it backwards in the guide 31 (Figs. 7, 8).
  • the bias of the clamping plate is created simply by the weight thereof.
  • the weight is dimensioned so that the desired clamping force is obtained when the device is arranged in the illustrated orientation in which the clamping plate 25 is disposed above the cable support track 17.
  • the clamping plate also can be biased by spring force. This is not illustrated in the Figures.
  • the guide 31 is designed to guide the upper part 9 of the connector 3 and is arranged in a fixed position relative to the cable support track 17.
  • the connector is inserted into the guide 31 upside down, i.e. with the upper part being below.
  • the connector location 15 is defined by a block 39 which comprises an abutment profile 41 for the connector 3.
  • the block 39 is secured in the guide 31 by means of a screw 43.
  • a plurality of throughgoing openings 45 for the screw 43 are provided in the bottom of the guide 31 at mutual distances in the direction of the guide, whereby the block 39 can be secured along the guide 31 in different positions.
  • a continuous adjustability can be obtained by providing a slot instead of individual openings 45.
  • the adjustability of the block 39 can be useful or necessary for adaptation to different embodiments of connectors.
  • a pin 47 is provided in the illustrated embodiment, which is secured in the block 39 and enters into a groove 49 of the clamping plate 25.
  • the groove 49 is disposed so closely besides the adjacent end of the clamping plate 25 that if desired, the clamping plate, after having been lifted, also can be pivoted about the pin 47 away from the cable support track 17. This can be appropriate if a connector shall be connected to a throughgoing cable; in such a case, the device would have to be designed without the abutment 29, for instance by correspondingly reducing the height of the wall of the guide 31 which forms the abutment 29.
  • a cable channel 51 (Fig. 3) is formed between the cable support track 17 and the clamping plate 25, which limits the insertion path of the cable 1 laterally.
  • the front end of the part of the cable channel 51 disposed in the clamping plate 25 is chamfered.
  • the base plate 37 is provided with mounting holes, for instance 53, so that it can be easily attached at any point.
  • a snapping device can be provided which cooperates with the connector 3 when the latter is in the cable receiving position (at the connector receiving location 15), whereby the correct position of the inserted connector can be recognized more easily as a snapping-in process.
  • a snapping spring 55 which is suitable as a snapping device is illustrated, which cooperates with a mounting hole of the connector 3.
  • the corresponding mounting hole 57 at the other end of the connector 3 is also illustrated.
  • the pressing-together of the connector is effected at the connector location by means of any suitable device, for instance a press having a limited pressing force.
  • Figs. 9 and 10 is particularly suited for the frequently occurring case of working with flat conductor cables which have different widths, i.e. different numbers of conductors, but are structurally similar in other respects.
  • a cable support track 917 is provided with a width so that the track is suited for a given maximum number of conductors, for instance 64, and comprises a corresponding number of grooves 921.
  • a guide 931 for a connector to be attached extends transversely of the grooves 921, and a block 939 is provided which is adjustable along the guide 931 and determines the connector location 915.
  • the block 939 is connected with a lateral stop 59 for a longitudinal edge 61 of an end portion of a flat conductor cable 901 to be introduced, whereby the position of a cable 901, in the direction of the guide 931, which is introduced while being in contact with the stop 59, is dependent upon the setting of the block 939.
  • a pressing force center point 63 (corresponding to the area where the center of a non-illustrated pressing ram will be effective) which is predetermined on the device will be disposed centrally of the introduced cable 901 and the non-illustrated connector. This is advantageous with a view to a uniform pressing-together of the connector.
  • a second lateral stop 65 is provided in the illustrated embodiment, which is also adjustable in the direction of the guide 931, and which is shifted to the other longitudinal edge 67 of the cable 901 so that an introduction channel fitting in width will result between the lateral stops 59 and 65.
  • the front ends of the lateral stops 59 and 65 are provided with chamfers 69 and 71, respectively, in the embodiment illustrated.
  • the lateral stops are provided, in the embodiment illustrated, on their bottom sides each with at least one protrusion which enters into the grooves 921.
  • Such a protrusion 73 can be recognized in the larger illustration of Fig. 10.
  • the protrusions are radiused in order that they can slide over of the grooves 921 when the side stops 59, 65 are adjusted, and the cable 901 can be easily taken out laterally after the attachment of the connector, with the second side stop 65 being displaced upwardly by the flat conductor cable.
  • a graduation 75 is provided which indicates the position of the block 939 in the guide 931 and comprises markings 77 for different numbers of conductors, i.e. certain widths, of the employed type of flat conductor cable 901.
  • the graduation 75 is designed so that with an adjustment to the number of conductors of the particular cable 901 introduced, the pressing force center point 63 will be disposed substantially centrally of the cable width.
  • the block 939 and the lateral stop 59 are adjustably supported at the clamping plate 925.
  • This has the advantage that the clamping plate 925 and the lateral stop 59 are lifted in common, and the support of the clamping plate 925 can be designed in any manner on the device, independently of the block 939.
  • the second lateral stop 65 is, in the embodiment illustrated, adjustably supported at the clamping plate 925.
  • the support of the clamping plate 925 comprises, similarly as according to Figs. 1 to 8, a pin 947 which engages into a groove 949.
  • Mounting blocks 79 and 81 serve as a lateral delimitation of the support and for holding the pin.
  • the clamping plate 925 has, as in the embodiment according to Figs. 1 to 8, a chamfered introduction funnel 935 which leads, in the advancing direction 919, to the support surface 83 proper of the clamping plate 925.
  • the clamping plate 925 furthermore has a plate-shaped extension 85 which extends oppositely to the advancing direction 919 and serves to guide the lateral stops 59 and 65.
  • the lateral stops 59 and 65 are guided at the front surface 87 and the lower surface of the extension 85.
  • Screws extend from those continuations through slots 93 and 95, respectively, which extend parallel with the guide 931.
  • nuts 97 and 99 respectively, screwed onto those screws, the lateral stops 59 and 65 can be clamped fast.
  • the continuation 89 of the first lateral stop 59 continues to form the block 939.
  • handling is facilitated in that the clamping plate 925 comprises a conveniently grippable handle 101 so that removing of a cable with the connector attached thereto can be conveniently facilitated by lifting the clamping plate 925.
  • the introduction path of an end portion of a cable 901 is limited in the advancing direction 919 by an abutment 929 which can be moved out of the introduction path.
  • the device can be used also with continuous cables.
  • the abutment 929 is designed at a shifting piece 103 which is shiftable in a slot which extends parallel with the guide 931, and can be clamped fast by means of a screw knob 107.
