Definitions

  • the invention is based on a contact carrier according to the generic type of independent claim 1.
  • the invention is based on a method for changing the operating state of an electrical system, in particular an escalator, according to the independent secondary claim 17.
  • Connectors with short-circuit bridges are required in particular for carrying out maintenance work on electrical systems, e.g. on escalators.
  • this connector has an insulating body in which six contact sockets are arranged.
  • two of the contact sockets can be "bridged", ie by one of the Bridges are electrically connected to each other.
  • the contact pins belonging to a bridge and thus also the contact sockets opposite them and to be bridged, can be configured to form corresponding pairs.
  • These pairings can be adapted to the respective requirements by changing the printed circuit board to another corresponding printed circuit board.
  • the electrical system e.g. the escalator
  • the electrical system e.g. the escalator
  • the closed housing cover thus corresponds to the operating state.
  • operation is interrupted and a test plug can be plugged into the connector as a mating plug instead.
  • the open housing cover thus corresponds to the maintenance status.
  • the pamphlet CN 202 797 560 U discloses the use of molded U-shaped contact pins for this design as an alternative to the configurable printed circuit board.
  • German Patent and Trademark Office has researched the following prior art in the priority application for the present application: DE 81 21 654 U1 , DE 44 13 043 A1 , JP 2001-110511A , DE 694 04 001 T2 , JP 2013-12437 A , DE 10 2004 018 554 A1 , DE 20 2011 108 572, U1 and US 2014/0057483 A1 .
  • the pamphlet DE 81 21 654 U1 further discloses a configurable keying plug with wires to each other crossing electrical connections of conductor tracks of a printed circuit board.
  • This publication discloses a coding plug with a housing whose base part has passages spaced apart by the printed circuit board grid and whose cover closes off the base part, and with U-shaped conductor bridges made of wire, the middle bar of which has a length corresponding to the distance between two printed circuit board passages and the legs of which consist of the base part stick out.
  • the object of the invention is to provide a robust device which a handy switching between a Maintenance and an operating condition of an electrical system, such as an escalator, permitted.
  • a Maintenance and an operating condition of an electrical system such as an escalator
  • a contact carrier is used to hold a number of U-shaped contact pins to produce short-circuit bridges and is suitable for being releasably arranged in a housing cover of a connector.
  • the contact carrier is designed in at least two parts, i.e. it can be designed in two parts, three parts, four parts, ..., n parts, for example.
  • the contact carrier can have at least two parts, at least three parts, at least four parts, ..., at least n parts.
  • the contact carrier advantageously consists of an electrically insulating material, preferably plastic.
  • the contact carrier can be detachably held in the housing cover of the plug connector and can preferably be held so that it can move within a predetermined tolerance range.
  • the U-shaped contact pins arranged in the contact carrier are used to create electrical short-circuit bridges in relation to contact sockets, which are arranged in an insulating body of the connector. On the cable connection side, these contact sockets can be electrically conductively connected, for example, to components of an electrical system, in particular an escalator.
  • the multi-part i.e. at least two-part, e.g. at least three-part form of the contact carrier
  • the paths of the U-shaped contact pins which form the bridges (short for "electrical short-circuit bridges"), to cross within the contact carrier.
  • the U-shaped contact pins can be removed and/or inserted individually from the contact carrier, e.g. by separating and assembling the several parts of the contact carrier. For example, a specific bridge can be removed and/or added as needed, with very little effort.
  • the U-shaped contact pins can have a relatively large cross section compared to the conductor tracks of a printed circuit board.
  • the parts of the multi-part contact carrier can snap together and/or be glued together after the U-shaped contact pins have been inserted. In the case of gluing, however, the possibility of removing them and thus the possibility of changing the configuration of this contact carrier is no longer available from this point in time, or is at least severely restricted. On the other hand, latching also allows this contact carrier to be reconfigured later.
  • the U-shaped contact pins are able to be automatically inserted into the respective contact socket of the connector by closing/closing, in particular by means of a pivoting movement, of the housing cover and thereby in each case a pair of contact sockets provided for this purpose electric to bridge, ie to electrically conductively connect the two contact sockets that form this pair.
  • the use of the contact carrier is extremely advantageous compared to a solution in which simple contact pins are soldered to a printed circuit board or in which U-shaped contact pins are simply inserted into the housing cover and e.g. encapsulated with a plastic compound.
  • the multi-part contact carrier has the advantage, for example, that individual U-shaped contact pins can be manually removed from the contact carrier and/or inserted into it at any time. As will be explained later, this can also be used to change the operating status of the electrical system, e.g. the escalator.
  • a certain so-called “play" of the contact carrier in relation to the housing cover in which it is held in this way can create mechanical tolerances that are necessary in order to close the housing cover of the connector housing, i.e. fold it closed, or open it, i.e open to be able to, even while the U-shaped contact pins, at least partially, are inserted into the contact sockets of the connector.
  • the solution according to the invention thus has the advantage that it is stable and flexible. This play can be realized, for example, by arranging at least one, preferably two, positioning pins in the housing cover, which have a circular cross section.
  • the contact body can have suitable positioning openings for receiving these positioning pins, which have a slot-like cross section, the minor axis preferably being aligned parallel to the axis of rotation of the housing cover and the major axis preferably being aligned perpendicular thereto. This allows the contact carrier in the pivoting direction of the housing cover have said tolerance, be positioned perpendicular to it and at the same time be held with its latching arms in the counter-latching arms of the housing cover.
  • the configuration of the bridges can be adapted at any time to a desired changed function of the operating state within the possibilities specified by the contact carrier, for example by suitably exchanging, arranging, removing and/or adding individual U-shaped contact pins in/from the contact carrier.
  • the contact carrier can, in addition to its said at least two parts, have a third part that can be attached to the parts connected to one another, in particular a cover that can be snapped onto it.
  • the contact carrier can have at least one upper part and one lower part and said cover, so that in this case the contact carrier is designed in at least three parts overall.
  • the upper part can first be attached to the lower part.
  • the cover can then be attached to the upper part and, in particular, fastened to the lower part, eg latched.
  • the cover can have, for example, fastening tabs with locking windows, with which it locks onto locking projections on the lower part. In a preferred embodiment, this latching also allows the upper part to be held on the lower part.
  • the cover has a protective surface with which it rests against the upper part when it is in place and thereby covers at least one or optionally also several contacts running through the upper part, in particular through at least one contact receptacle of the upper part .
  • This protective surface reliably prevents, for example, manual contact with at least one current-carrying contact pin.
  • the lid can therefore have a dual function, namely both an electrical Safety function as well as a mechanical, constructive fastening function.
  • the electrical safety function is particularly advantageous because - at least theoretically and/or in the event of damage - when the housing cover of the connector is opened, there is a risk that the contact carrier detachably attached to it will unintentionally become detached from the housing cover on the one hand, while the contact pins accommodated therein will become detached on the other are still plugged into the insulator and are thereby mechanically held to it.
  • this does not correspond to the intended use of the contact carrier, but represents a possible source of danger in the event of incorrect operation or damage, since the contact pins can ultimately be in electrical contact with socket contacts arranged in the insulating body. In the worst case, at least one of these socket contacts, and thus also the contact pin connected to it, can even carry a life-threatening electrical voltage.
  • a contact carrier that has finally been individually configured by the user, ie provided with the desired U-shaped contact pins, and in particular also its cover to the other parts, in particular to be glued to the upper and lower part, because the lid is then finally no longer removable.
  • another contact carrier which has the new, desired configuration, can of course be replaced with the contact carrier currently used exchanged, ie fixed in the housing cover instead of it.
  • new bridge connections are also made possible in a cost-effective and uncomplicated manner, for which no contact receptacles are provided in the contact carrier to be replaced.
  • this method is suitable for the use of bonded contact carriers, in particular contact carriers with a cover that is bonded for safety reasons.
  • the detachably fastened contact carrier offers an extremely flexible and, at the same time, very easy-to-use solution, which can be easily handled, flexibly and cost-effectively adapted to a given assignment on the cable connection side.
  • a contact carrier for a ten-pole connector is suitable for receiving five U-shaped contact pins, which then each form a bridge between the pairs of contact sockets 5-10; 4-6; 1-7; 2-8; form 3-9. If the bridge between the contact sockets 5-10 and the bridge between the contact sockets 2-8 is no longer desired, the corresponding U-shaped contact pins can be removed from the contact carrier with little effort by suitably separating individual parts of the contact carrier.
  • the contact carrier is advantageously removed from the housing cover beforehand and then fastened to it again, which is possible with very little effort, in particular due to the common latching mechanism. Thereupon when the housing cover is closed, only the contact socket pairs 4-6; 1-7; 3-9 bridged.

  • Both the upper part and the lower part can have through-openings at the ends of each contact receptacle leading to the respective contact surface for the passage of contacts, in particular for the passage of plug-side end regions of the U-shaped contact pins.
  • the lower part can also have additional through-openings, which connect to the through-openings of the upper part when the contact carrier is in the assembled state.
  • the upper part and the lower part can have latching means, for example latching hooks and latching recesses, for mutual latching and unlatching. These locking means can also have a positioning function.

However, gluing does not have to be done at the factory, but can also be carried out by the customer after the final configuration/equipment of the contact carrier has taken place, which means that the jumper assignment can still be customized flexibly.
  • the contact carrier has polarization and latching means for its polarization relative to the insulating body of the connector and for its latching and unlatching on the housing cover.

  • the Indian Figure 3a The first contact pin 8 shown has, compared to the other contact pins 8', 8'', relatively long plug-side end regions 81 because it is intended for use in the upper part 31, while the other contact pins 81', 81" are intended for use in the lower part 32.
  • the second contact pin 8' shown has a middle area 82' which is shorter than the middle area 82 of the first contact pin 8 and longer than the middle area 82" of the third contact pin 8".
  • the Indian 3c The third contact pin 8" shown has a middle area 82" which is shorter than the middle area 8' of the other contact pins 8, 8'.
  • the Figure 4a shows this arrangement in an exploded view.
  • the upper part 31 and the lower part 32 are shown separately and each with the U-shaped contact pin(s) 8, 8′, 8′′ arranged above them and to be inserted therein.
  • first contact element 8 is intended to be arranged with its central area 82 in the first contact receptacle 316 .
  • second and third contact element 8', 8" are intended to be arranged with their respective central area 82', 82" in the second and third contact receptacle 316', 316".
  • Two positioning pins 317 of the upper part 31 can also be seen in this illustration, only one of which is labeled for reasons of clarity.
  • the upper part 31 has two further such positioning pins 317 which are arranged symmetrically thereto and cannot be seen in this illustration.
  • these four positioning pins 317 are inserted into the corresponding, slightly funnel-shaped positioning recesses 327 of the lower part 32 in order to ensure the exact positioning of the assembled upper 31 and lower part 32.
  • the Figure 4b shows the upper part 31 and the lower part 32 during the mutual assembly process.
  • the second 8′ and third 8′′ contact pins are already inserted into the lower part 32, ie their respective central areas 82′, 82′′ are arranged in the second 326′ and third 326′′ contact receptacles and their plug-side end areas 81′, 81′′ are through the corresponding passage openings 328 and the corresponding hollow-cylindrical projections 323 of the plug-in area 325 of the lower part 32 out.
  • the first contact element 8 is about to be inserted with its middle part 82 into the first contact receptacle 316 of the upper part 31 . Its end regions 81 on the plug-in side have already passed through the corresponding through-openings 318 in the upper part 31 and are about to be inserted into the further through-openings 322 in the lower part 32 .
  • FIG. 4c shows the contact carrier 3 assembled from the upper part 31 and lower part with the U-shaped contact pins 8, 8', 8" inserted therein.
  • the positioning openings 319, 329 of the upper part 31 and lower part 32 come to rest on one another.
  • the Figure 4d shows the contact carrier 3 in a slightly modified version.
  • the upper part 31 has four feedthrough indentations 310 .
  • the lower part 32 has four latching indentations 320, each with a latching formation 3201 arranged therein.
  • the contact carrier 3 has a cover 33.
  • the cover 33 has a rectangular protective surface 334 and fastening tabs 331 which are formed onto the protective surface 334 and which each have a locking window 330.
  • the Figure 4e shows the assembled contact carrier 3'.
  • the cover 33 is arranged with its protective surface 334 on the upper part 31 and thereby covers the U-shaped contact pin 8 running through the first contact receptacle 316 of the upper part 31.
  • the fastening tabs 331 are guided through the feed-through indentations 310 of the upper part 31 and engage in the latching indentations 320 of the lower part 32 and latch with their latching windows 330 on the latching formations 3201 of the lower part 32.
  • the cover 33 can be attached to the upper part 31 and to the lower part 32.
  • the previously mentioned U-shaped contact pin 8, which runs through the upper part 31, could carry a high electrical voltage in some applications, for example. Normally, this would not be dangerous, because the contact carrier 3 is also fastened in the housing cover 10 and the contact pin 8 is therefore not accessible. However, in the event of damage and/or incorrect operation, there could be a risk of contact with this contact pin 8, for example by hand. In the case of the contact carrier 3 ′ in the present embodiment, this is reliably avoided by the electrically insulating protective surface 334 of the cover 33 . In addition, the lid 33 can fasten both itself and the upper part 31 to the lower part 32 in this way. The cover 33 thus has a dual function, since it is used for mechanical attachment and also for electrical safety. The latter applies in particular if the contact carrier 3' is glued in the assembled state.
  • the Figure 5a shows this arrangement from the direction of the plug-in area 325.
  • the slot-shaped cross-sectional shape of the positioning opening 319 of the upper part 31 can also be seen particularly well.
  • the Figure 5b shows the same object in cross-section through a cross-sectional area A. Both the first 8 and a second 8' U-shaped contact pin with the respective plug-side end region 81, 81' can be seen clearly.
  • the Figure 5c shows the lower part 32 equipped with the corresponding U-shaped contact pins 8', 8'' with a view of its contact surface 4.
  • the slot-shaped cross-sectional shape of the positioning opening 329 of the lower part 32 can also be seen particularly well.
  • the Figure 5d Figure 12 shows the same article in cross-section through a cross-sectional area B passing through the third contact receptacle 326''.
  • the Figure 6a shows the housing cover 10 without the contact carrier 3.
  • the positioning pins 109 and its latching hooks 101 with the latching pins 103 formed thereon can be seen particularly well.
  • the positioning pins 109 have a cylindrical section, ie a section with a circular cross section.
  • This housing cover 10 is shown with the contact carrier 3 inserted therein with the U-shaped contact pins 8, 8', 8" accommodated therein as contact bridges. It can be seen from this view that the positioning opening 329 is in the form of an elongated hole, while the cross section of the positioning pin 109 is circular, at least in its corresponding cylindrical section.
  • the Fig. 6f shows this arrangement with the housing cover closed in a lateral cross section through the third contact receptacle 326" of the contact carrier 32.
  • the contact sockets 28 are also shown and labeled for the first time. It can be clearly seen that the third U-shaped contact pin 8" has two opposite contact sockets 28 with electrically connected to each other.
  • the contact sockets 28 can be connected, for example, to electrical components of an electrical system, as a result of which these components are thus short-circuited.
  • the correct orientation between the insulating body 2 and the contact carrier 3 is through the L-shaped polarization element 311 and through at least one Polarization bar 211 'of the insulating body 2 guaranteed.
