Definitions

  • the invention relates to a distribution strip with a plurality of conductor connections arranged next to one another and comprising conductor rail pieces and a transverse distribution of the electrical power.
  • Distribution strips of the generic type are used for the supply-related and control-related connection of electrical components such as voltage sources and signal receivers. For this purpose, they can be used, for example, to build up initiator terminal blocks, as set out, for example, in EP 0 222 030 A2.
  • the supply lines of a voltage source are connected to two distribution strips located in an initiator terminal block and the supply voltage is distributed from there via internal cross-connection strips to a plurality of connecting terminals arranged next to one another, to which supply lines are connected, for example, from initiators for electrical signal receivers.
  • the structure of the distribution strips used for this application is relatively complex since additional components such as spacer sleeves must be present between the conductor rail sections of the conductor connections and the components for the actual transverse distribution of the electrical power, with a transition resistance naturally occurring with each current transfer between the components.
  • the object of the present invention is therefore to create a distribution strip of the generic type in which the transverse distribution of the electrical power takes place with the least possible constructional and assembly-related effort.
  • the solution according to the invention consists in that for the transverse distribution of the electrical power, the conductor rail pieces of the conductor connections have plug contact elements for the electrical connection of the conductor rail pieces to one another.
  • the plug contact elements automatically form an electrical connection when the conductor connections are lined up laterally to form a distribution strip by latching a plug contact in a socket contact, so that there is no additional control during assembly to determine whether all cross connections of the cross distribution have been made.
  • the plug-in connection of the busbar pieces of the individual conductor connections these can be joined together to form distribution strips of any length, ie any number of conductor connections.
  • distribution strips can be constructed for any purpose, which in turn can be used, for example, for the construction of initiator terminal blocks Find the number of poles. The space requirement can thus be reduced considerably, depending on how often such distribution strips are used.
  • the busbar pieces have a U-shaped base body, each with two lateral spring contact legs which form the socket contact and are arranged on one of the legs, a plug tab.
  • the plug tab of a plug-in contact element engages in each case in the socket contact of the plug-in contact element of an adjacent busbar piece in order to produce the electrical connection of the busbar pieces to one another.
  • the conductor to be connected to the conductor connection is, for. B. directly connected to the conductor rail piece of the corresponding conductor connection via a clamping spring.
  • the plug and socket contact are thus made in one piece, which lowers the manufacturing costs and simplifies assembly.
  • one of the plug contact elements as a socket contact offers the possibility of the socket part from several directions z. B. to contact from the side or from below. Since the socket contact of the first conductor connection of a distribution strip is not required for the connection to the next conductor rail section or for the construction of the overall conductor rail, there is the possibility here of creating an additional connection possibility for a circuit board arranged under the conductor connections if necessary.
  • connection area of the conductor connection is very easily accessible from above, in addition to the connection possibility already mentioned, all other usual types of connection of the conductor connection can also be realized via a clamping spring.
  • the socket contact of the individual conductor rail piece is accessible both from below and from the side, additional contact surfaces can be arranged on the socket contact for feeding current into the distributor strip, which contact surfaces can both engage in the socket contact and can establish an electrical connection on the outer surface of the socket contact.
  • a U-shaped fork contact for making electrical connections at the socket contact is also conceivable.
  • the fork-shaped contact has the advantage that, in principle, current can be fed in from anywhere at any point on the distributor strip. This is particularly the case when space is limited save a special feed terminal.
  • a distributor strip of the type according to the invention is of great advantage in particular for the construction of initiator terminal blocks, as briefly described at the beginning.
  • the special design of an initiator terminal block provides that at least two distributor strips are arranged in a basic housing of an initiator terminal block, which can be fixed on a mounting rail.
  • the connection to the basic housing is made using detachable plug fasteners, so that the distributor strips can be regrouped in the initiator terminal block in a simple and easy-to-assemble manner.
  • the already mentioned possibilities of an advantageous simple coding of the distributor strip according to the invention make the often necessary grounding of busbar connections seem very simple to implement. Due to the accessibility of the busbar sections from below, a connection of the distribution strip to the mounting rail carrying the earth potential can be implemented without problems.
  • the detachable connection of the distribution strips within the initiator terminal block base housing is a contact for connection via plug contacts, i. H. makes the implementation of PNP or NPN circuits very easy by simply repositioning the distribution strips.
  • FIG. 1 shows a distributor strip, designated in its entirety by 1, which consists of three conductor connections 2, which are arranged next to one another and are identified by the numbers I-III.
  • each conductor connection there is one busbar piece 4, which each interlock with the aid of their plug contact elements 5.
  • the structure of a conductor connection 2 is illustrated with the aid of the sectional diagram in FIG. 2.
  • the conductor rail section 4 can again be seen there.
  • a clamping spring 14 is arranged, which serves to press the conductor 3 from above into the insertion funnel 13 of the conductor connection housing 10, to press under the busbar piece 4 and to fix it there by clamping spring force.
  • On the top of the conductor connection housing 10 there is a mounting opening 15 on the side next to the insertion funnel 13, through which an actuation of the clamping spring 14 for the mounting process of the conductor 3 is possible.
  • Each wire junction box has on one side wall connecting cams 12, which correspond in position and size with corresponding connecting bores 11 on the opposite side surface of the conductor connection housing 10, so that when a row of conductor connections 2 is lined up, these engage one another by the engagement of the connecting cams 12 in the corresponding connecting bores 11 of the adjacent conductor connection 2 are set.
  • each busbar piece 4 located in each conductor connection 2 engage with one another by means of their plug contact elements 5, so that an electrically conductive connection between the individual conductor connections 2 is established.
  • three busbar pieces 4 are shown in FIG. 3, the corresponding conductor connection housings 10 being omitted for better understanding.
  • Each busbar piece 4 has a U-shaped base body 21, which consists of two spring contact legs 23 and 24 and a leg connecting plate 25 connecting them.
  • the holding tab 22 protruding laterally on the spring contact leg 24 and angled at an angle of approximately 45 ° serves to hold the busbar piece 4 in its position in the conductor connection housing 10.
  • Both the spring contact leg 23 and the leg 24 are laterally extended to the side opposite the retaining tab 22.
  • the spring contact leg 24 has a plug tab 27 at its extended free end.
  • the spring contact leg 23 is cranked in the direction of the opposite spring contact leg 24 in such a way that at the opposite free ends of the two legs there are two mutually opposite surfaces provided with contact plates 28 and 29 , whose distance is less than that of the spring contact legs 23 and 24 in the area of Base body 21.
  • the opposite surfaces provided with the contact plates 28 and 29 together form a socket contact 26.
  • the clamping spring 14 is shown on a conductor rail piece 4 in FIG. 3, which is placed on the outside of the spring contact leg 24. It has an opening 30 on its side facing the retaining tab 22 and is shaped in such a way that it generates a spring force in the direction of the arrow F. Since the retaining tab 22 protrudes through the opening 30, the movement of the free leg 32 of the clamping spring 14 in the direction of the arrow F is limited. If a counterforce is exerted on the edge 31 of the clamping spring 14, its free leg 32 moves downward with the opening 30 counter to the arrow F, so that the busbars enter the interior of the U-shaped base body 21. piece 4 a connecting wire can be inserted.
  • FIG. 3 shows that the first socket contact 26 of a distributor strip is not required for the current transmission within the busbar. For this reason, this socket contact, like the connection of the conductor rail piece 4 to a conductor 3, can be used to establish a further electrical connection to the conductor rail.
  • 1 and 2 show a possibility of contacting the busbar from the underside of the conductor connection 2 via the socket contact 26.
  • the exemplary embodiment shows a solder contact 42, which is electrically connected to a circuit board 41 and has at its end facing away from the circuit board 41 a contact plate 43 which engages through an opening 44 on the underside of the conductor connection housing 10 in the socket contact 26 of the busbar piece 4.
  • the fork contact 40 is electrically connected to a printed circuit board 41 and engages around the socket contact 26 from below, in which case the conductor connection housing 10 has a sufficiently dimensioned cutout 45 on its underside.
  • the fork contact 40 can attack a distribution strip 1 at any conductor connection 2, provided that it is in the conductor connection housing 10 the corresponding cutout 45 for receiving the fork parts of the contact 40 which laterally encompass the socket contact 26 is present.
  • a distributor strip of the type according to the invention can thus be positioned as desired over a fork contact 40 arranged in a printed circuit board 41.
  • the power rail can be fed in from below, which is otherwise necessary omitted, which is particularly advantageous when space is limited.
  • FIG. 5 shows an example of an initiator terminal block in cross section with three conductor connections 2 belonging to distribution strips according to the invention.
  • An initiator terminal block is composed of initiator terminal blocks 50 which are arranged next to one another perpendicular to the plane of the drawing and which are fixed to one another perpendicularly to the plane of the drawing shown on a common standardized mounting rail 54.
  • the stringing together of the initiator terminal blocks 50 inevitably also results in a stringing together of the individual conductor connections 2 to form distribution strips, which are denoted by I, II and III in FIG. 5.
  • the initiator terminal block 50 has a terminal housing 51 made of insulating material, which is provided with mounting webs 80 for releasably fixing the conductor connection housing 10 in the terminal housing 51. These receiving webs 80 have small beads 81 which engage in corresponding recesses 82 in the conductor connection housing. This design ensures that the conductor connections 2 can be interchanged within a terminal block to z. B. convert a PNP arrangement into an NPN arrangement.
  • the busbars of the individual distribution strips I, II and III naturally also offer the possibility of contacting from the underside of the conductor connection housing 10 when used in initiator terminal blocks.
  • a contacting is used to connect the busbar of the distribution strip 3 to the mounting rail 54 for assembly shown a PE distribution strip.
  • the connection is made through the contact bracket 58, which is through the insertion funnel 53 of the conductor housing 10 engages in a socket contact of the busbar of the distributor 3. Since the contact bracket 58 penetrates into the socket contact, the contact must necessarily be made at the beginning of the distribution strip, since there is a free socket contact here.
  • the contact bracket 58 is riveted to a transmission plate 59, which is fixed in the initiator terminal housing 51 and touches the mounting rail 54, so that the corresponding electrical connection is established.
  • the initiator terminal housing 51 is usually fixed on the mounting rail 54 by means of two housing feet 56 and 57 which grip around the angled holding limbs 61 of the mounting rail 54.
  • FIG. 6 An initiator terminal block is shown in FIG. 6, in which the switching state of the initiator is indicated by a control LED 70.
  • a contact plate 72 engages in a conductor connection of the distributor strip from below.
  • the contact plate 72 is part of a contact angle 71, which is connected to the control LED 70 via a wire bridge 73 and a resistor 74.
  • the contact plate 72 does not engage in the middle of a socket contact on the busbar of the distributor strip, as in the case of the contact bracket 58 described in FIG. 5, but touches one of the spring contact legs of the socket contact 26 laterally.
  • the contact plate 72 is positively guided via the insertion funnel 76 such that contact other than the lateral contact of the socket contact is not possible.
