Definitions

  • the invention relates to a method for pressing the press-in sections of contact elements of multi-pin plug connectors into holes in a printed circuit board, the contact elements being arranged in columns and rows in a carrier body made of insulating material and initially being held in recesses in the insulating body by means of frictional engagement, the contact elements using a comb-like tool in the holes in the printed circuit board are pressed in, and the press-in force is transmitted to the tool via the corresponding shoulders on the tool and on the contact elements, and a tool for carrying out this method.
  • the force to be applied to the tool for pressing is determined by the number of press-in sections of the contact elements to be pressed in at the same time and assumes considerable values as the number of contacts increases.
  • z. B. 96-pin connectors are already applied forces in the order of 5 - 15 000 N.
  • the force to be applied when the contact elements are pressed in at the same time is of the order of 25-75,000 N.
  • such forces cannot be applied with the presses generally available for mounting the connector strips, or only with enormously large presses.
  • the invention is therefore based on the object of specifying a method for pressing the contact elements of multi-pin plug connectors into printed circuit boards, in which the forces to be applied are reduced and which is as simple and economical to use as possible.
  • the contact elements are pressed into the bores of the printed circuit board in at least two working steps, the pressing force being exerted only on a first part of the contact elements in the first working step and these being pressed into the printed circuit board bores, the carrier body of the connector is pressed against the circuit board surface and not with the Press-in force applied contact elements move with their press-in section only into the upper areas of the printed circuit board bores and are then pushed upwards into the recesses in the insulating body, and in a second or, if necessary, subsequent work step, the press-in force on the remaining pushed up or possibly on one Part of the pushed-up contact elements is exerted, these being pushed back into the recesses in the insulating body and at the same time the press-in sections thereof being pressed into the holes in the printed circuit board.
  • Another object of the invention is to provide the simplest possible tool for carrying out the method.
  • the advantages achieved by the invention consist in particular in that, by pressing in only a part of the contact elements in each case in two or, if appropriate, also several work steps, one for each work step relatively low, ie force to be applied with normal hand lever presses or pneumatic presses must be applied to the tool.
  • the tool required for this is easy to handle, with the remaining contact elements which were not pressed in during the first working stroke now being pressed in by simply laterally displacing or moving the tool for the second working stroke.
  • a tool that is rotatably mounted on a carrier is also particularly easy to use. After the first working stroke, the tool is simply swiveled by 180 ° and then the second working stroke is carried out to press in the remaining contact elements.
  • FIG. 1 a connector 1 is shown, the contact elements 2 can be pressed into the holes 4 of a circuit board 5 using a tool 3, while in Fig. 2, the tool in connection with the connector and the circuit board after performing a first step of the press-in process is shown, and wherein FIG. 2A shows an enlarged detail for clarification of details.
  • the contact elements provided with a press-in section 6 are inserted into an insulating body 7, this having recesses 8 for receiving a holding section 9 of the contact elements into which the contact elements are inserted and held there by friction are.
  • the arrangement of the contact elements 2 is provided in columns and rows, the grid of this arrangement corresponding to the grid R of the printed circuit board holes 4 into which the ends of the contact elements are to be pressed.
  • the contact elements are provided in their front end with a short insertion 10, which is in front of the press-in section 6 and which has a smaller cross section than the press-in section.
  • a short insertion 10 which is in front of the press-in section 6 and which has a smaller cross section than the press-in section.
  • the connector preassembled with the contact elements is placed on the printed circuit board in such a way that that the ends 10 of the contact elements protrude into the printed circuit board bores, and then the press-in tool 3 is pushed onto the contact elements and these are pressed in.
  • the tool is provided with recesses 11 which are arranged in accordance with the grid of the contact elements and into which the upper ends 12 of the contact elements are immersed when the tool is placed on. In the illustration of FIG.
  • the tool is provided with press-in shoulders 13 for every 1st, 3rd, 5th, etc. column of the contact elements, which press on the contact elements onto the upper shoulders 14 of the mounting sections 9 when the tool is placed on it and press these contact elements with their press-in sections 6 into the printed circuit board holes 4 when the tool is pressed down.
  • Further shoulders 15 on the press-in tool simultaneously press onto the bottom 16 of the insulating body and press it against the top 17 of the printed circuit board.
  • enlarged recesses 18 are provided in the tool. These recesses are so large that the holding sections 9 of the contact elements of these columns can dip into the tool when the tool is pressed down.
  • the contact elements of every 1, 3rd, 5th, etc. column are pressed into the circuit board holes and the insulating body is pressed against a circuit board.
  • the tool is then removed from the connector and a second tool is placed on the connector.
  • This tool is designed like the first tool, except that the recesses in the 1st, 3rd, 5th, etc. column of the contact element positions are interchanged with those in the 2nd, 4th, 6th, etc. column, so that press-in shoulders are now used for the shoulders of the holder sections of the contact elements not yet pressed into engagement and the holder sections when the tool is pressed down pushed back into the recesses 8 of the insulating body and the press-in sections of these contact elements are simultaneously pressed into the circuit board holes.
  • all the contact elements of the connector are pressed in. If necessary, it can be provided that the contact elements are pressed in in more than two working steps.
  • a plurality of press-in tools are then provided, a part of the contact elements being pressed in in each work step (press-in stroke).
  • the pressing in of the contact element is preferably provided in two work steps, the tool being mounted on a carrier 20 and being able to be pivoted about a bearing point 21 by 180 ° about the axis X.
  • the bearing point is arranged in the tool with respect to the recesses 11, 18 in such a way that, after the tool has been pivoted through 180 °, the contact elements which were pressed in during the first working step are immersed in the enlarged recesses 18 and the contact elements which were not pressed in, are in positions in which the press-in shoulders 13 of the tool come onto the shoulders 14 of the mounting sections 9 of these contact elements and press them into the circuit board when the tool is pressed down.
  • the tool locking means 22 such as. B. ball catches provided on the carrier 20 or tool 3.
  • a connector which has an asymmetrical insulating body with respect to the rotation of the tool, it is preferably provided that two end pieces 23 are fixedly mounted on the carrier 20, each pressing the outer columns of the contact elements and that only the central part 24 of the Tool 3 is provided rotatable by 180 °.
  • an end piece 25 of a modified tool is shown, which is provided for connectors which are provided with a circumferential collar 26 of the insulating body 7.
  • the tool end would be placed on the collar of the insulating body in the second working step and destroy it.
  • the end piece 25 of the tool which strikes the insulating body collar in the second working step, can slide back against the force of a spring 27 into the recess 28 of the tool or the carrier 20 against the pressing-in direction.
  • the end piece 25 is prevented from evading by the bottom 29 of the carrier and presses the contact elements when they hit them.
  • the second step which is shown in Fig. 4, the end piece after the lateral displacement of the tool comes under the spring 27 or recess 28 of the carrier and slides back when it hits the insulating collar 26, ie into the recess.
