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 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.

Description
- 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. - In a known device of the kind indicated (US-A-4 020 540) 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.
- From the US-A-4 561 178, an apparatus for installing electrical connectors on flat cables has become known, wherein a guide track is provided for guiding connectors from a staging zone into the application zone where electrical connectors are applied to the flat cables. The connectors are successively fed to a turn table which can be rotated to align the receiving position of the turn table to the guide track so that a ram may push the connector to the guide track where it is applied to the flat band cable end.
- It is an object of the present invention to provide a structurally simple device which is suited for automation and by which multi-contact connectors can be simply, conveniently, and rapidly connected to multi-core flat band cables.
- According to the invention, that object is attained by the device according to
claim 1. - In the device according to the invention, 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. In the device according to the invention, 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.
- In total, there results from a most simple structure a very simple mode of operation which permits high working speeds when working manually as well as in the case of mechanized, automatic operation. Automation will not be difficult.
- Preferably, 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.
- Further, the 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.
- Normally, 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. According to a development of the invention, the guide is designed for the insertion of the upper part and is arranged in a fixed position relative to the cable support track. Thus, it is not necessary to provide a relative movability between the cable support track and the guide, because the relative movement which is necessary to close the connector can be performed solely by pressing-on the lower part which is arranged on top.
- With the device according to the invention, about 10 to 15 connectors per minute can be connected by manual work. With the initially described known device, only a fraction of that working speed can be obtained.
- For the sake of completeness, it should be mentioned that it is known to shift a flat band cable manually into a pre-assembled bipartite connector and to connect it by pressing the connector together. In doing so, an exact guiding and smoothening of the cable cannot be sufficiently ensured because of the limited dimensions of the connector, and the manual threading-in the cable is time-consuming and forms a step which cannot be automated at an acceptable expense.
- Furthermore, there are automatic connecting devices in which the two parts of the connector and the flat cable to be connected are brought up from stock and assemble automatically. While a threading-in will be avoided in this manner, the mechanical expense is considerable.
- The invention will be subsequently described by means of embodiment examples in connection with the drawings.

- 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 withcutting contact elements 5, and anupper part 9 guided thereon. By pressing theparts direction 11, they can be transferred from the open position illustrated in Figs. 2 and 5 in which anopening 13 is formed between theparts cable 1, into a closed position (Fig. 7) in which the connector is electrically and mechanically connected to thecable 1. - 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 thecable 1, as illustrated in Fig. 5. The device furthermore comprises acable support track 17 on which thecable 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). Thecable support track 17 hasgrooves 21 for slidingly guiding thelongitudinal ridges 23 of thecable 1 which are formed by the cable cores (Figs. 2, 5). - The device furthermore comprises a
clamping plate 25 which is movable relative to thecable support track 17 and in the illustrated embodiment also hasgrooves 27 in an arrangement corresponding to thegrooves 21 of thecable support track 17. - It is appropriate to limit the insertion of the cable into the connector by an abutment which can be provided at the device or at the connector 3. In the illustrated embodiment, such an
abutment 29 is provided at the device. - At the device, a
straight guide 31 leading to theconnector location 15 is provided, in which an open connector 3 to be connected can be advanced into the receiving position, i.e. into theconnector location 15. - The
clamping plate 25 is supported to be movable parallel with itself in a direction normally of thecable support track 17, i.e. normally of the advancingdirection 19 of the cable 1 (Figs. 2, 5). Theclamping plate 25 is biased towards thecable support track 17 and forms at itsfront surface 33 which faces away from theconnector location 15 an insertion hopper 35 with thecable 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 thecable support track 17 is shifted inwards and outwards transversely of thecable support track 17, i.e. in the illustrated embodiment in the direction of theguide 31, whereby the completely connected connector can be removed from the device simply by moving it backwards in the guide 31 (Figs. 7, 8). - In the illustrated embodiment, 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 thecable support track 17. Alternatively, or in addition thereto, the clamping plate also can be biased by spring force. This is not illustrated in the Figures. - In the illustrated embodiment, the
guide 31 is designed to guide theupper part 9 of the connector 3 and is arranged in a fixed position relative to thecable support track 17. Thus, the connector is inserted into theguide 31 upside down, i.e. with the upper part being below. - In the illustrated embodiment, a particularly simple structure is obtained in that the
cable support track 17 as well as theguide 31 which simply is formed as a straight groove are formed unitarily in abase plate 37. - In the illustrated embodiment, the
connector location 15 is defined by ablock 39 which comprises anabutment profile 41 for the connector 3.Theblock 39 is secured in theguide 31 by means of ascrew 43. In the illustrated embodiment, a plurality ofthroughgoing openings 45 for thescrew 43 are provided in the bottom of theguide 31 at mutual distances in the direction of the guide, whereby theblock 39 can be secured along theguide 31 in different positions. Also, a continuous adjustability can be obtained by providing a slot instead ofindividual openings 45. The adjustability of theblock 39 can be useful or necessary for adaptation to different embodiments of connectors. - For supporting the clamping
plate 25, very simply apin 47 is provided in the illustrated embodiment, which is secured in theblock 39 and enters into agroove 49 of the clampingplate 25. Thegroove 49 is disposed so closely besides the adjacent end of the clampingplate 25 that if desired, the clamping plate, after having been lifted, also can be pivoted about thepin 47 away from thecable 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 theabutment 29, for instance by correspondingly reducing the height of the wall of theguide 31 which forms theabutment 29. - In the illustrated embodiment, a cable channel 51 (Fig. 3) is formed between the
cable support track 17 and the clampingplate 25, which limits the insertion path of thecable 1 laterally. For forming theinsertion hopper 35, the front end of the part of thecable channel 51 disposed in the clampingplate 25 is chamfered. - The
base plate 37 is provided with mounting holes, forinstance 53, so that it can be easily attached at any point. - If desired, 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.
- In Fig. 5, 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.
- In Figs. 9 and 10, parts which appear correspondingly in Figs. 1 to 8, are designated with the same reference numerals as there, however, with a prefixed "9". Insofar, with respect to Figs. 9 and 10, reference is also made to the description of Figs. 1 to 8.
- The embodiment according to 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.
- In a
base plate 937 which comprises mountingholes 953, acable 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 ofgrooves 921. As according to Figs. 1 to 8, aguide 931 for a connector to be attached (not illustrated) extends transversely of thegrooves 921, and ablock 939 is provided which is adjustable along theguide 931 and determines theconnector location 915. Theblock 939 is connected with alateral stop 59 for a longitudinal edge 61 of an end portion of aflat conductor cable 901 to be introduced, whereby the position of acable 901, in the direction of theguide 931, which is introduced while being in contact with thestop 59, is dependent upon the setting of theblock 939. Thus, it can be particularly achieved that 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 introducedcable 901 and the non-illustrated connector. This is advantageous with a view to a uniform pressing-together of the connector. In order to facilitate and ensure the introduction in contact with thelateral stop 59, a secondlateral stop 65 is provided in the illustrated embodiment, which is also adjustable in the direction of theguide 931, and which is shifted to the otherlongitudinal edge 67 of thecable 901 so that an introduction channel fitting in width will result between the lateral stops 59 and 65. In order to facilitate the introduction of the cable end portion, the front ends of the lateral stops 59 and 65 are provided withchamfers 69 and 71, respectively, in the embodiment illustrated. In order that the lateral stops are always correctly aligned with one of thegrooves 921, the lateral stops are provided, in the embodiment illustrated, on their bottom sides each with at least one protrusion which enters into thegrooves 921. Such aprotrusion 73 can be recognized in the larger illustration of Fig. 10. The protrusions are radiused in order that they can slide over of thegrooves 921 when the side stops 59, 65 are adjusted, and thecable 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. - In the embodiment illustrated, a
graduation 75 is provided which indicates the position of theblock 939 in theguide 931 and comprisesmarkings 77 for different numbers of conductors, i.e. certain widths, of the employed type offlat conductor cable 901. Thegraduation 75 is designed so that with an adjustment to the number of conductors of theparticular cable 901 introduced, the pressingforce center point 63 will be disposed substantially centrally of the cable width. - In the illustrated embodiment, a particularly simple structure is obtained in that the
block 939 and thelateral stop 59 are adjustably supported at theclamping plate 925. This has the advantage that the clampingplate 925 and thelateral stop 59 are lifted in common, and the support of theclamping plate 925 can be designed in any manner on the device, independently of theblock 939. For the same reasons, also the secondlateral stop 65 is, in the embodiment illustrated, adjustably supported at theclamping plate 925. In the illustrated embodiment , the support of theclamping plate 925 comprises, similarly as according to Figs. 1 to 8, apin 947 which engages into agroove 949. Mountingblocks - In the illustrated embodiment, 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 thesupport surface 83 proper of theclamping plate 925. In the illustrated embodiment, the clampingplate 925 furthermore has a plate-shapedextension 85 which extends oppositely to the advancing direction 919 and serves to guide the lateral stops 59 and 65. To this end, the lateral stops 59 and 65 are guided at thefront surface 87 and the lower surface of theextension 85. Relativelythin continuations 89 and 91, respectively, of the lateral stops 59 and 65, respectively, extend across the lower surface of theextension 85. Screws extend from those continuations throughslots 93 and 95, respectively, which extend parallel with theguide 931. By means ofnuts 97 and 99, respectively, screwed onto those screws, the lateral stops 59 and 65 can be clamped fast. Thecontinuation 89 of the firstlateral stop 59 continues to form theblock 939. - In the illustrated embodiment, handling is facilitated in that the clamping
plate 925 comprises a convenientlygrippable handle 101 so that removing of a cable with the connector attached thereto can be conveniently facilitated by lifting theclamping plate 925. - Furthermore, in the embodiment illustrated in Figs. 9 and 10, the introduction path of an end portion of a
cable 901 is limited in the advancing direction 919 by anabutment 929 which can be moved out of the introduction path. Thereby, the device can be used also with continuous cables.
