Definitions

  • the invention relates to a filter plug with a pin header body made of plastic, which has a chamber that is open to at least one side, with a number of parallel connector pins arranged in a grid, which from the rear of the chamber through a floor into the chamber ⁇ mer enter and exit to the open side of the chamber, and with at least one filter element, in particular a ferrite body, which has holes in the grid of the plug pins, plugged onto the plug pins and by at least one spring element made of plastic molded onto the pin header body in the axial direction of the Plug pins is kept in the chamber.
  • a filter plug is known from DE-G 90 05 597.
  • the ferrite bodies plugged onto the plug pins serve to decouple electromagnetic interference.
  • this requires laborious manufacturing steps, in particular the curing of the adhesive being associated with a loss of time in mass production.
  • adhesive connections are not possible with some plastics used for pin header bodies of a plug.
  • DE-GM 89 12 173 discloses a filter plug with tubular ferrite bodies which are pressed against the bottom of a chamber by means of a plastic holding strip, the holding strip being formed in the grid of the plug pins and onto which the ferrite bodies are inserted , and the chamber floor is formed with the cones opposite frustoconical approaches.
  • the retaining strip is designed as a separate individual part and fastened to the pin strip body in recesses in the pin strip body with lateral latching hooks.
  • integrally molded spring elements are provided on the chamber bottom of the pin header body, the ferrite core inserted into the connector pins inserted into the chamber counteracting by means of a shield housing which is latched onto the strip body against the force of the spring elements is pressed into the chamber and held there.
  • the ferrite core is thus fixed in the final position only after the chamber with the shield housing has been closed by an additional component.
  • the object of the invention is now to enable an even simpler, but at the same time safe and tolerance-insensitive mounting of a filter element in the case of a filter plug of the type mentioned at the outset with a filter element fastening integrated in the pin strip body.
  • the chamber is formed with lateral guides for the filter element provided with run-in bevels
  • the spring element is on a side wall of the pin header body running laterally to the chamber bottom, to the side of the filter element arranged and comprises an arm resilient transversely to the insertion direction of the filter element, which is angled at its ends approximately at right angles in the opposite direction
  • the one angled end of the arm of the spring element is formed on the side wall and the free angled end of the arm is formed with a locking lug protruding into the insertion area of the filter element, which latches into the chamber when the filter element is inserted into the chamber and plugged into the connector pins and thus arranged and is designed so that it presses the engaged filter element against the chamber bottom.
  • the filter element With such a filter plug, the filter element is inserted into the lateral guides of the chamber and onto the plug pins and snapped into the chamber with slight pressure. After the snap-in lug of the spring element has snapped onto the filter element, the latter is already positioned without further measures and additional means and is securely fixed in its position.
  • the inlet bevels which form an insertion channel tapering in the direction of insertion of the filter element, make installation easier and are arranged lying to the side of the filter element in such a way that the filter element is in the correct position even before the spring element is actuated.
  • a filter plug according to the invention is provided with a filter element fastening integrated in one piece in the pin header body, so that the pin header body and the filter element form a unit to be prefabricated which consists of only two components and which is completely equipped on a base, e.g. B. a printed circuit board, can be arranged.
  • the arrangement of the spring element to the side of the filter element between this and a side wall of the pin strip body, in cooperation with the design of the spring element with an arm resilient transversely to the direction of insertion of the filter element, has the advantage that an adequate spring length can be achieved despite limited space.
  • Another advantage of this arrangement is that the spring element is torque-free in the direction of loading and has a certain elasticity, which is important for absorbing shock loads.
  • the filter element is designed as a one-piece, strip-shaped ferrite body of elongated extension.
  • the spring element extends between the filter element and the side wall of the pin header body in the longitudinal direction of the filter element.
  • Adequate lateral guidance for the filter element is obtained if the lateral guides are arranged at two opposite ends of the filter element.
  • the side guides are each formed by two clamps, which are laterally spaced from one another corresponding to the width of the filter element.
  • two spring elements are provided which are integrally formed with respect to one another with respect to the center of the length of the filter element and are symmetrically formed on the side wall and engage symmetrically on the filter element.
  • the spring element is approximately rectangular in cross section and is arranged in an upright position in relation to the chamber floor. It is expedient if the latching lug of the spring element is arranged in an upright position between two connector pins. This results in a particularly space-saving arrangement of the filter element attachment with an optimal effect of the spring element.
  • the spring travel required for secure engagement can be kept small.
  • the latching lug is designed with a bevel on its end face and the angle between this bevel and the insertion direction is chosen to be as small as possible.
  • the distance between the side wall is expedient the pin header body and the arm of the spring element matched both to the necessary deflection and to the bendability of the arm. This ensures on the one hand a necessary deflection for the engagement and on the other hand prevents the spring element from being overstretched.
  • Figure 1 is a plan view of a portion of a filter plug containing a filter element
  • Figure 2 shows a section II-II of Figure 1.
  • the filter plug has a pin header body 1 made of plastic, which has on its right outside a chamber 3 which is open in FIG. 2 to a printed circuit board 2 and to the right side.
  • This chamber is formed by a front and a rear side part 4 or 5 as well as a side wall 6 of the pin strip body 1 and a further side wall, which is integrally formed at about the middle of the height of the side wall 6 and the chamber bottom 7 forms.
  • the filter plug also has a number of parallel plug pins 8 arranged in a grid, which penetrate the side wall 6, then run parallel under the chamber floor 7, are bent approximately at right angles and from the rear of the chamber through the chamber floor into the chamber 3 enter and exit to the side of the chamber which is open towards the printed circuit board 2.
  • the filter plug is also equipped with a filter element 9, which is designed as a one-piece, strip-shaped ferrite body of elongated expansion and in the grid of the plug pins 8 bores. has stanchions 10 with which it is plugged onto the connector pins.
  • the chamber is formed with lateral guides 15 and 16, which are provided with run-in slopes 11, 12 and 13, 14, respectively two opposite ends of the elongated ferrite body 9 are arranged and are formed by two brackets 15a, 15b and 16a, 16b which surround the corners of the ferrite body.
  • brackets are arranged on the inside of the side parts 4 and 5 of the pin header body 1 opposite one another, two brackets 15a, 15b and 16a, 16b being laterally spaced from one another approximately at a distance of the width B of the ferrite body.
  • the inlet slopes 11, 12 and 13, 14 of the guides 15, 16 each form an insertion channel tapering in the insertion direction 17 of the ferrite body 9.
  • two spring elements 18 are provided here, which extend laterally of the ferrite body 9 between it and the side wall 6 in the longitudinal direction of the ferrite body and are integrally formed on the side wall 6 perpendicular to the chamber bottom 7, for. B. are molded.
  • the spring elements 18 are essentially formed by an arm 19 which extends parallel to the side wall 6 in its longitudinal direction and is angled at its ends approximately at right angles in the opposite direction, the one angled end 20 approximately in the middle of the length of the ferrite body 9 is integrally formed on the side wall 6 so that the arm 19 can spring transversely to the insertion direction 17 of the ferrite body, while the free angled end 21 of the arm 19 is formed with a locking lug 22 which projects into the insertion region of the ferrite body and which into the chamber ferrite body inserted and plugged into the connector pins 8 engages there and is arranged and formed such that it presses the engaged ferrite body 9 against the chamber bottom 7. As can be seen from FIG.
  • the two spring elements 18 are integrally formed in mirror image on the side wall 6 with respect to the center of the length of the ferrite body and engage symmetrically on the ferrite body.
  • the spring ele- ducks 18 are approximately rectangular in cross-section and are arranged in an upright position relative to the chamber bottom 7, the latching lug 22 of the spring elements engaging in an upright position between two plug pins 8 on the ferrite body.
  • the insertion direction 17 is selected in the direction of the ferrite body 9 which has the smallest tolerances, ie in the direction of the height H of the ferrite body.
  • the locking lug 22 of the spring elements 18 is formed on its end face with a bevel 23, the angle 1 between this bevel and the insertion direction 17 being chosen to be as small as possible.
  • the latching edge of the latching lug 22 is also designed with a bevel 24, the clearance angle 2 between this slope and the bearing surface of the latching lug on the ferrite body 9 being selected such that the clearance angle has a self-inhibiting effect against the latching out of the ferrite body. So that the latching lug 22 can engage at all on the ferrite body 9, the width B of the ferrite body in the insertion direction 17 has a gradation 25 extending over the entire length of the ferrite body. However, it is sufficient if the ferrite body is designed with a pocket-shaped recess for the locking lug at those points at which a locking lug of a spring element engages.
  • the distance A between the side wall 6 of the pin header body 1 and the arm 19 of the spring elements 18 running parallel thereto is matched both to the necessary deflection and to the bendability of the arm 19.
  • the end 20 of the arm 19 formed on the side wall 6 of the pin strip body is formed with transition radii 26, 27, 28 both in the connection area on the side wall 6 and in the connection area on the arm 19.
  • the filter element 9 is elongated and is fixed with two spring elements 18 extending laterally and along the filter element.
  • the filter element can be adequately fixed in the insertion direction, if appropriate also with a single spring element.
