Definitions

  • the invention relates to a press for pressing connectors into printed circuit boards, in particular press with a C-shaped press body, the printed circuit board, in the bores of which the press-in sections of the contact element ends of a connector are pressed by means of a press ram / pressing tool, rests on a press table, and wherein the Press is provided with resilient, resilient means.
  • Presses with a C-shaped press base body are preferably used for pressing plug-in connectors into printed circuit boards, since the press body, which is open on one side, is particularly well suited to being able to hold printed circuit boards of various formats for pressing.
  • press-in forces When pressing multi-pin connectors into printed circuit boards, high press-in forces are required, which can be up to 150 N for each contact end to be pressed in. With plug connectors used today with up to 500 contacts, press-in forces of up to 75 kN can then be applied.
  • a C-shaped press body tends to spring elastically.
  • the press ram and the press tool associated with it move originally from it vertical or horizontal position by an angle corresponding to the spring deflection.
  • This displacement / misalignment has the result that, in particular, connectors to be pressed in which are arranged longitudinally in the opening direction of the C-shaped press are pressed obliquely into the printed circuit board, so that one end of the connector is pressed into the printed circuit board until the support body stops, but the other end is not completely pressed in until it stops.
  • the invention is based on the object of designing a commercially available, C-shaped press such that a springing open of the press body remains without influence on the required plane-parallel pressing of, in particular, connectors arranged longitudinally to the press opening into the printed circuit board.
  • the resilient, resilient means are arranged in such a way that they prevent the inclination of the press-in tool, i.e. counteract the inclination of the underside of the press-in tool in relation to the printed circuit board or the connector to be pressed in, when the arms of the press spring open during the press-in process, so that the underside of the press-in tool is always plane-parallel to the printed circuit board, i.e. that the tool always acts vertically on the connector to be pressed.
  • the advantages achieved by the invention are, in particular, that a bending of the arms of the C-shaped press body occurring during the press-in process and the resulting misalignment of the press-in tool with respect to the printed circuit board or the plug-in connector to be pressed in are compensated for, so that the press-in tool is plane-parallel during the press-in process to the circuit board on the press table.
  • the press shown in FIG. 1 has an essentially C-shaped press body 1, a press cylinder with a vertically acting press ram 3 being arranged on the upper arm 2 and a press table 5 being arranged on the lower arm 4.
  • the press table there is a printed circuit board 6 with a connector 7 placed thereon, the contact element ends of which are pressed into holes in the printed circuit board when the press ram is pressed down by the press tool 8 connected thereto.
  • the connector is placed on the circuit board so that its longitudinal axis runs in the direction of the opening of the C-shaped press body.
  • the two arms 2, 4 of the press body become C-shaped due to the elasticity that is always present Body bent out with relatively wide arms by the forces occurring during the pressing process, so that the bottom 9 of the press tool no longer runs plane-parallel to the surface 10 of the lower arm 4 with the press table.
  • the connector is then pressed obliquely into the circuit board in such a way that the front end 11 of the connector facing away from the opening of the C's is not completely pressed into the circuit board holes.
  • the front end 12 of the press table is rotatably / pivotably mounted about the axis X. Furthermore, a spring element 13 is arranged under the other, rear end of the press table, on which the press table rests.
  • a support part 14 is provided, on which a plate spring 15 is fastened by means of a pin 16.
  • the pin is movably held in the supporting part in the vertical direction, the plate spring being prestressed by means of a nut 17.
  • the spring characteristic of the spring element ie the plate spring, is selected in accordance with the spring characteristic of the arms of the C-shaped press body.
  • the rear end of the press table is deflected / pivoted back by an amount Y when the press-in force acts on it corresponds to the spring deflection of the arms 2.4, so that the press-in tool acts exactly perpendicularly on the press table / the connector during the actual press-in process.
  • the spring element is fastened horizontally displaceably to the lower press arm.
  • a slot 18 is formed in the press arm, through which a clamping screw 19 is guided, with which the spring element can be locked in different positions (see FIG. 1).
  • a modified press is shown in FIG. It is provided that the press cylinder 20 with the press ram 3 and the press tool 8 is arranged via a joint 21 at the lower end of the upper arm 2 of the press body.
  • a tension spring 22 as a spring element between the press cylinder and the upper end of the arm 2 pulls the press cylinder against a stop 23 on the upper arm.
  • FIG. 4 a further modified press is shown in FIG. 4.
  • the press-in tool 8 ' is of divided design, namely an upper and a lower part 24, 25 are provided which are connected to one another in an articulated manner about a front axis X'.
  • a spring element 13 ' is arranged between the two parts, which acts in accordance with the spring element 13 described at the beginning and one when the arms 2, 4 of the press body spring open Compensation for the resulting misalignment of the press tool in relation to the connector to be pressed.
  • the axis of rotation Z about which the arms 2, 4 of the press spring open during the press-in process, is approximately at the height of the press table, so that the horizontal displacement (relative movement) between the vertical axes of the press-in tool and the connector is avoided .
  • This greater elasticity of the connection of the lower arm 4 to the vertical arm 26 of the press can be achieved, for example, in that the vertical arm is designed with a reduced cross section at the height of the press table 5.
