Definitions
- the invention relates to a device with a contacting device with the following features:
- the contacting device comprises a receiving part with a cable channel open on one side,
- the cable duct has a bottom of width b and two side walls adjoining it,
- a first of the two side walls has a contour with a step through which the cable duct narrows towards the bottom
- a shape-coded flat cable with a coding lug can be inserted into the cable duct, the width of which has an outer surface corresponding to the width b and an adjoining side surface whose contour corresponds to the contour with the step of the side wall,
- a generic device is known from EP 0 821 434 AI, which discloses a module for connecting actuators and / or sensors.
- the module is composed of a mounting plate and an upper housing part.
- the upper part of the housing can be swiveled onto the mounting plate while at the same time making contact with the contact pins of a flat cable.
- the mounting plate is provided with a cable duct that is open on one side, into which a form-coded flat cable with a coding lug can be inserted in a form-fitting manner.
- the cable duct has a bottom corresponding to the width of the flat cable and an adjoining side wall which is provided with a contour which is stepped in accordance with the coding lug of the flat cable.
- Such devices are used when using the actuator sensor interface bus system described in DE 295 01 970 U1.
- This bus system allows a maximum cable length of 100 m for the two-core profiled flat cable. Due to the defined contour of the cable duct with coding lug, it can only be inserted in the appropriate position. Accordingly, loops may be required when laying the flat cable in preassembled devices.
- An alternative solution would be the laborious disassembly of some devices. Because of the problem mentioned, it can also happen that pre-assembled cables cannot be used depending on the distances between the devices. In addition, when using two parallel flat cables, care must be taken that the position of their coding lugs is the same.
- the second side wall is designed with a stepped contour mirror-symmetrical to the first side wall.
- This device has a contacting device with the following features:
- the contacting device comprises a receiving part with a channel open on one side, with a bottom and with two contoured side walls,
- the slide in both positions to the interior of the respective cable duct, the slide has a contour with a step through which the cable duct narrows towards the floor,
- each of the cable channels formed in this way is a form-coded flat cable with a coding lug
- the channel is opposite three contact elements distributed over the channel width, of which the middle contact element in conjunction with one of the outer contact elements serves to contact the two-wire flat cable which can be inserted into the cable channel and has a corresponding contour.
- FIG. 1 shows a cross section of a device according to the invention with cable channels for receiving a flat cable in the non-contacted condition
- Figures 2, 3 a cross-sectional view of the apparatus of Figure 1 with inserted in 'the cable ducts flat cables in a different position in the contacted state
- 4 shows a perspective view of the device according to FIG. 1, comprising a base plate and a pivotable upper part.
- the base plate 1 shows an electrical device composed of a base plate 1 and an upper part 2 that can be swiveled open in the unopened state.
- the base plate 1 contains two parallel cable ducts 3 and 4 of different designs which are open on one side towards the upper part 2. Both cable channels 3, 4 are arranged opposite one another in the upper part 2, contact spikes 5 and 6, which here, in connection with the cable channels 3 and 4, are essential components of a contacting device for a shape-coded, two-core flat cable 7.
- the electrical device is shown with the upper part 2 pivoted onto the base plate 1 and with a flat cable 7 inserted in the cable duct 3 or 4 in a different position and contacted by the contacting tips 5 and 6, respectively.
- the cable duct 3 is symmetrical. It has a flat bottom 8 and side walls 9 which are mirror-symmetrical to one another.
- the side walls 9 are each provided with a step 10 such that the cable channel 3 narrows towards the bottom 8 through them.
- a two-wire flat cable 7 with a coding lug 11 is inserted into the cable duct 3, each of the two contact tips 5 making contact with one of the two line wires in a different installation position of the flat cable 7 according to FIGS.
- the side surface formed by the coding lug 11 has a contour that corresponds to the contour with the step 10 of the side walls 9 of the cable duct 3.
- the flat cable 7 lies with one of its outer surfaces on the bottom 8 and with the stepped side surface on the side wall 9 in a form-fitting manner. Due to the symmetrical design of the cable duct 3, the flat cable 7 can be inserted into the cable duct 3 after rotation through 180 °, so that a cable is also inserted positive engagement of the side surface with coding nose 11 takes place on the opposite side wall 9.
- the polarity is changed, ie the line wires can only be contacted with the other contact tip 5.
- a rectifier is connected upstream of the electronics (not shown here) connected to the contact tips 5.
- FIGS. 1, 2 and 3 An alternative solution for accommodating the flat cable 7 is represented by the cable duct 4 according to FIGS. 1, 2 and 3.
- This is formed according to FIG. 1 by a symmetrically designed duct 12 with an inserted slider 13.
- the channel 12 has a bottom 14 and contoured side walls 15 which are mirror-symmetrical to one another.
- the slider 13 can be inserted into the channel 12 under contact with at least partial positive locking on one or the other of the two side walls 15.
- the contours of the two cable channels 4 formed in this way coincide up to a rotation through 180 ° about an imaginary axis which is perpendicular to the base 14.
- the slider 13 has a contour with a step 16, through which the cable duct 4 narrows towards the bottom 14.
- the shape-coded flat cable 7 with the coding lug 11 which has a side surface with a contour that corresponds to the contour with the step 16 of the slider 13, can be inserted in such a way that the flat cable 7 with one of its outer surfaces on the form-fitting Bottom 14 and with its side faces on the slide 13 and at least partially on the opposite side wall 15 of the channel 12.
- the channel 12 is opposite three contact tips 6 distributed over the channel width as contact elements, of which the middle contact tip 6, in conjunction with one of the outer contact tips 6, serves to contact the flat cable 7 inserted in the cable channel 4 with a corresponding contour.
- the middle contact tip 6 with the same line is in both installation positions of the flat cable 7 wire contactable. Depending on the installation position, one or the other outer contact tip 6 is available for contacting the other line wires. As a result, the operation can be carried out without changing the polarity, so that the use of a rectifier is unnecessary.
- the slide 13 can be designed symmetrically with a stepped contour of two side surfaces.
- the base plate 1 can have at least one further identically designed cable duct 3 or 4.
- the base plate 1 is provided with the parallel cable ducts 3, 4 according to FIGS. 1, 2 and 3, in each of which the two-wire flat cable 7 described above is inserted.
- the upper part 2 is designed in an adapted position with contact tips 5 or 6.
- two rows, each with two contact tips 5 arranged in the longitudinal direction of the cable duct 3, are provided.
- three rows each with two contact tips 5 located in the longitudinal direction of the flat cable 7 are available.
