Definitions

  • the invention relates to a connector for electrically contacting a printed circuit board with the features contained in the preamble of claim 1.
  • Printed circuit boards are usually equipped with components on one side, the so-called “component top side”.
  • so-called “wired components” are used in which out of curved wires connecting legs are passed through holes through the printed circuit board and electrically contacted on the so-called “soldering bottom” with a printed circuit.
  • Such a conventional assembly of printed circuit boards has the disadvantage that the printed circuit boards can be provided only on one side with wired components in particular for manufacturing technology reasons. The resulting separation into a component top side and a solder bottom on the printed circuit board producing the majority of the electrical connections results in a maximum component density which can not be exceeded.
  • an electrical device e.g. a programmable logic controller
  • a common rack summarizes printed circuit boards in a common rack summarize.
  • Such subracks are preferably designed in so-called standard construction.
  • the individual printed circuit boards are thereby inserted parallel next to each other vertically in the rack.
  • At the front end edge of each printed circuit board is provided with a label and preferred display and controls front panel.
  • At the opposite rear end edge is at least one, in particular designed as a male connector. If the respective assembly inserted into the rack, so this connector preferably engages in a particular designed as a female connector connector counterpart, which is mounted inside the rack.
  • the connector counterparts of all summarized in a rack printed circuit boards are finally connected together in a so-called backplane wiring in a suitable manner.
  • the position of the parallel printed circuit boards in the rack may preferably in standard construction systems depending on a ge Standard, smallest distance measure can be specified. In this way, it is possible depending on the current width of one of the vertical printed circuit boards to provide for this a well-defined slot in the interior of the rack between adjacent, parallel-standing printed circuit boards.
  • the width of such a standard installation space advantageously corresponds to a multiple of the preferably standardized, smallest distance dimension in the rack.
  • To fix the vertical printed circuit boards on the lower and upper longitudinal edges serve rail-like guide and support strips, which can be latched into mounting holes in the mounting frame. In particular, by the mutual distance of such mounting holes preferably standardized, smallest distance in a standard construction system, and thus the possible width of each slot for one of the parallel printed circuit boards is specified.
  • the location of one of the vertical printed circuit boards within the space provided for this purpose is essentially determined by the shape and arrangement of the connector at the rear end edge.
  • Such connectors for electrical contacting of printed circuit boards are mounted eg on the top of the component and contacted there in SMT technology or the connecting legs are passed through holes through the printed circuit board and contacted on the soldering bottom.
  • such an arrangement has an eccentric position of the vertical printed circuit board within the associated slot result. If, for example, when looking at the front side of a subrack, the components top side of a printed circuit board assembly to the right and the soldering bottom side to the left are located, then in this case the base plate of the printed circuit board is in the left-hand area of the associated mounting location. In this way, while it can be avoided with certainty that, for example, when pulling the module from the rack unwanted touch, for example, between the components on the component top and the soldering bottom of an adjacent, located immediately adjacent slot further printed circuit board take place.
  • the invention has for its object to provide a connector for making electrical contact with a printed circuit board provided on both sides in particular with hybrid components.
  • FIG 1 is an example of a slot SEP for a vertical printed circuit board LP in a rack Darge provides. This is limited by the dot-dash lines marked I and V respectively.
  • a mounted on a front side ST of the printed circuit board PCB connector SV is used to supply or discharge of the electrical signals of the printed circuit board.
  • pins of the connector are guided on the printed circuit board.
  • these contact pins are preferably arranged in the rows KSR1, KSR2, KSR3.
  • the contact between the contact pins and the outer electrical connection elements of the connector is made.
  • the connector SV designed as a male connector in FIG.
  • these electrical connection elements are designed as blade contacts preferably also arranged in rows MKR1, MKR2, MKR3. These blade contacts preferably project out of the connector SV in a trough-shaped blade contact opening MKO. They engage in insertion of the printed circuit board LP in the space provided in the rack slot SEP in particular in a connector counterpart, which is preferably designed as a spring bar.
  • the connector SV takes almost the width of the space provided for the PCB PCB slot SE. This is inventively almost in the middle of the standard installation space. This makes it particularly advantageous possible to equip not only the previous component top side BS, but also the previous soldering bottom side LS in particular with surface mountable components. Due to the approximately central position of the base plate of the printed circuit board in the slot SEP a sufficient distance to the boundary lines I and V of the printed circuit board assigned slot is guaranteed despite both sides, in particular hybrid placement with components. At least the distance from the previous soldering bottom LS to the opposite boundary line I is just so great that in particular SMD components can be mounted on the soldering bottom.
  • the subrack receiving the printed circuit board is designed in standard construction, it is possible to attach guide and support strips for fixing the printed circuit board LP inserted in the subrack to the dot-dash lines marked II, III or IV in FIG. These positions are spaced apart from one another by the smallest distance measure KRM characterizing the respective standard construction system in the manner described above.
  • the advantageous embodiment of a connector SV according to the invention shown in FIG 1 has the particular advantage that the central position of the printed circuit board in the slot SEP just coincides with the standard position III in the rack. By simple arrangement of guide and support strips at this position, it is thus possible without further changes to accommodate a provided with the connector according to the invention SV and equipped with components PCB PCB in a standard standard slot SEP a designed in standard design subrack.
  • the illustrated in the Figure 1 advantageous embodiment of the connector according to the invention further has an investment side AU and an angle thereto arranged guide page FS.
  • the connector SV is advantageously placed with the guide side FS on one side of the printed circuit board, in the example of FIG 1 on the previous component top BS, while the front edge ST of the printed circuit board abuts the support side AU of the connector. With the help of such a connector constructed a mechanical high-strength connection to the printed circuit board LP can be produced.
  • the contact pins of the connector which are preferably arranged in the rows KSR1, KSR2, KSR3, are guided through the upper region SVO to one side of the printed circuit board.
  • this is the previous component top BS.
  • the pins are in a known manner by means of Bohrun gene passed through the printed circuit boards through to the previous solder side LS and contacted there electrically conductive, for example, with a conductor LB. Since the contact pins in the embodiment illustrated in FIG. 1 are supported by the upper region SVO of the inventive connector SV, the electrical contacting of the contact pins with the conductor tracks on the printed circuit board can also be achieved by means of compression.
  • the contact pins in extension of the blade contacts MKR1, MKR2, MKR3 out of the contact side AU of the connector out on the previous soldering bottom side LS of the printed circuit board LP.
  • the contact pins are outside the body of the connector SV and thus in particular not supported by the upper part SVO of the connector. It is particularly advantageous in this case, if the contact pins, e.g. in the manner shown in FIG 4 are guided to the solder bottom of the printed circuit board, that they can be contacted there electrically conductive in the manner known from the SMT surface mounting technology.
  • Such an embodiment has the particular advantage that no holes must be provided on the circuit board more. Rather, the connector according to the invention can be used together with SMD components in one operation in surface mount technology, e.g. be contacted on the previous solder bottom.
  • the arranged in particular in the rows KSR1, KSR2, KSR3 pins of the connector are guided on both sides of the printed circuit board LP.
  • the rows of contact pins KSR2 and KSR3 are in the previous way through the upper region SVO of the connector through to the previous component top side BS of the printed circuit board.
  • FIG 3 a further advantageous, two-shell embodiment of the connector according to the invention is shown.
  • the first row of blade contacts MKR1 and, in extension thereof, the first row of contact pins KSR1 guided on the soldering base are accommodated in a first half SV1 of the connector.
  • the rows MKR2, MKR3 of the blade contacts and the associated rows KSR2, KSR3 of the contact pins guided on the top side of the component are accommodated in a second half SV2 of the connector according to the invention.
  • Such a bivalve embodiment has the advantage, in comparison to the embodiment illustrated in FIG. 2, that no receiving slots have to be provided for the contact pins guided on one of the sides of the printed circuit board.
  • first contact pin row KSR1 in the first connector half SV1 and the contact pin rows KSR2, KSR3 in the second connector half SV2 can be contacted electrically conductively, for example, by surface mounting to the printed circuit board. If, in addition, the contact pins in both connector halves are completely enclosed, in particular by the respective connector upper regions SV10 and SV20, as shown in FIG. 3, the contact pins of the respective connector half can be contacted separately by pressing with the printed circuit board.
  • the connector according to the invention due to the approximately central position of the base plate of the printed circuit board within the designated slot now plate-shaped covers for one or both of the components equipped with components sides of the printed circuit board can be mounted in a simple manner.
  • a plate-shaped cover AB is shown as an example for the previous soldering bottom side LS preferably provided with surface-mounted components.
  • the connector according to the invention thus has means for supporting at least one such cover.
  • this holding means is designed in the form of a retaining slot HS present, for example, in the upper region SV10 of the first half SV1 of the two-shell connector.
  • FIG 4 serves as a holding means particularly advantageous surface of the connector SV, on which the cover plate AB is supported, for example by means of bonding.
  • a further, held on the second half SV2 of the connector cover for the previous component side BS of the printed circuit board can be provided.
  • the bivalve embodiment of the connector according to the invention it is thus particularly advantageous possible to easily reach a complete encapsulation of the circuit board by two-sided coverage of the two, in particular hybrid-equipped sides of the printed circuit board.
