Definitions

  • the invention relates to a connector for card edge mounting, in particular a 2- or multi-row connector for SMD connection with a circuit board, the circuit board connection side of the connector at least one rotatable or foldable with the connector insulating body connected pressure body in which the solder connections the contacts of the connector are held.
  • DE 195 11 508 A1 describes an electrical connector for card edge mounting known for connection to the surface of a printed circuit board, in which the PCB connection side a foldable with the connector insulator connected pressure body, in which the contact connections of the connector are held.
  • DE 195 30 994 C1 is a connector for card edge mounting known, in the contact springs in the inserted state of the circuit board rest on contact surfaces of the circuit board.
  • a connector for printed circuit boards is known from DE 38 22 980 C2, which has a pressure body, the resilient contact elements presses a flat electrical conductor.
  • the invention has for its object a connector of the beginning mentioned type to the effect that this in surface mounting can be attached to the circuit board, easy to assemble is and has a low overall height.
  • the connector of the invention has a high contact density and thus provided circuit board has only a small overall height, one optimal use of space for the common card height (320 contacts / 100 mm) is achieved by using both sides of the plug-in card simultaneously.
  • a Another advantage is the symmetrical arrangement of the connector to the daughter card (Straddle Mount).
  • the connector has the same installation conditions as existing 2.0 mm and 2.5 mm hard-metric "connector systems and the ability to be integrated into existing SMD assembly systems as well as an automatic fixation of the connector on the circuit board until soldering is also given.
  • the connection of the circuit board (daughter card) to a backplane circuit board (Backplane) via the connector in surface mounting technology the demand for components that are becoming ever flatter.
  • the connector can be built in two or more rows.
  • an insulating body 1 of a plug connector consisting of plastic is shown, in which two or more rows of a plurality of contact chambers 2 are embedded.
  • the connector is designed as a so-called SMD connector for surface mounting on or on a circuit board.
  • two guide elements 3 are attached laterally, which precenter the connector when plugged with a mating connector, for. B. ensure a male connector (which is not shown here).
  • the flanges 4 are provided with chambers 5 which are open on at least one side.
  • a trigger mechanism 6 is provided which, as shown in the figures, is rotatably mounted in a bearing 7 on the insulating body 1. Furthermore, there are two bearings 8 on the side of the insulating body 1. In the bearing 8, a pressure body 9, which likewise consists of insulating plastic, is rotatably mounted on the insulating body 1. Two flanges 10 are also attached to the pressure body 9 on the back.
  • the pressure body 9 is opened by the trigger mechanism 6, as shown in FIGS. 1, 2 and 4 and mouth-like "for inserting a circuit board.
  • the release mechanism 6 latches in this open position.
  • the pressure element 9 is pretensioned by springs 11, which are located in the flanges 4 and 10.
  • the contacts are in the insulating body 1 in the area of the fixed seats 12, 13, 14, 15 16, 17, 18, 19, preferably as double-leg twisted contact springs are executed.
  • the contacts 16, 17, 18, 19 consist of the areas contact tulip 20, 21, 22, 23, fixed seat 12, 13, 14, 15 and the Solder terminals 24, 25, 26, 27.
  • the insulating body 1 On the back of the insulating body 1 is an existing plastic insulating guide body 28 mounted.
  • the solder terminals 26 and 27 of the Contacts 18 and 19 are in the guide body 28 and the solder connections 24 and 25 of the contacts 16 and 17 in the pressure body 9 out.
  • Through the guide body 28 and the pressure body 9 results in a very high coplanarity the contacts 16, 17, 18, 19 in the area of the solder connections 24, 25, 26, 27 and at the same time a defined insertion depth into the solder paste 29 the circuit board 30 reached.
  • the flanges 4 on the insulating body 1 and Flange 10 on the pressure body 9 are four metal solderable mounting flanges 31 attached, which after mounting the connector with the Printed circuit board 30 are soldered.
  • the mounting flanges 31 catch the Pulling and mating forces that occur when plugging and unplugging the connector arise from.
  • Fig. 2 and Fig. 4 show the state of assembly of the connector with the open and latched pressure body 9 in the side view and in Cut.
  • a connector is shown in which the pressure body 9 is on one side is rotatably mounted in the bearing 8 with the insulating body 1. The connector is pushed laterally onto a printed circuit board 30 and positioned in the correct position.
  • the trigger mechanism 6 While placing the connector on the top of the circuit board 30, the trigger mechanism 6 is triggered and unlocks the opened one and by the spring 11 biased pressure body 9.
  • the connector By the position of the bearing 7 in connection with a pivotable tip of the Trigger mechanism 6, which when folding the pressure body on the Acts on the top of the circuit board and exerts an axial force component, the connector is pulled to the front of the circuit board 30.
  • the connector is replaced by the spring force of the solder connections 24, 25, 26, 27 of contacts 16, 17, 18, 19 or by additional springs 11 fixed on the circuit board 30 until soldering.
  • Fig. 3 and Fig. 5 show the final state of the connector in a side view and on average with the release mechanism 6 unlocked and folded Pressure body 9.
  • the PCB is populated with the SMD components page by page, i.e. it is only one side of the circuit board with solder paste provided, then equipped with surface-mountable components and soldered. With a double-sided printed circuit board, this is then turned and the second side is provided with solder paste, equipped and soldered.
  • solder paste equipped and soldered.
  • the connection contacts of the surface-mounted components must pressed vertically into the solder paste at a defined depth be.
  • Another condition in surface mounting technology is conditional due to the placement machine itself, a weak or low-power Assembly of the components.
  • the Movable pressure body 9 presses on the circuit board 30 to support.
  • the necessary spring force can be achieved through the contacts 16, 17, 18, 19 or generated by additional springs 11.
  • solder connections 24, 25, 26, 27 of the Contacts 16, 17, 18, 19 of the connector in a guide body 28 or guided in the pressure body 9. This is necessary to achieve very high coplanarities to ensure.
  • solder connections 24, 25, 26, 27 of the connector with a defined depth in the solder paste 29 on the Printed circuit board 30 and the connector is simultaneously on the Printed circuit board 30 fixed.
  • solder as a solid Solder deposit on at least one of the two solder connections 24, 25 or 26, 27 the contacts of the connector is provided. This is because double-sided printed circuit boards the second side of the circuit board, only after the first page completely equipped with surface mounted components and is soldered, can be provided with solder paste.
