Definitions
- the invention relates to a plastic housing with an opening for pressing in a press-fit contact according to the preamble of claim 1.
- Press-fit contacts are electrical contact means which are used in electronic assemblies to connect electronic components on a printed circuit board to terminals on the outside of the housing. While previously such electrical contact means were usually encapsulated in the manufacture of the housing of the assembly with the plastic material, such contacts are increasingly pressed by pressing, so under the action of force in an opening in the plastic housing.
- Such a press-fit is thus pressed in a predetermined press-in, usually perpendicular to the corresponding region of the plastic housing in an opening provided therefor.
- the press-in contact has a first electrical contact region, a holding section adjoining thereto and a second electrical contact region, the holding section having at least sections a predetermined oversize relative to the opening in the plastic housing.
- Such a press-fit is often produced from a sheet by punching. This results in that the press-in contact preferably corresponds anywhere in a dimension of the thickness of the sheet.
- the opening has a holding section in a transverse direction, in which, at least in sections, the hole width is smaller by a predetermined amount than the width of the press-fit contact in this transverse direction.
- a press-fit (1) which in a relative to the press-in (X) perpendicular transverse direction (Z) is constantly wide, as is common, for example, in stampings, is advantageous for a defined and not too large press-fit that this holding section (HBZ ) is in the press-in (X) seen at the end of Einpressweges and extending in the press-in (X) only over a predetermined length (LHBZ) smaller the length of the entire opening in the pressing (X).
- the hole width of the opening in this transverse direction Z is thus reduced in the course of Einpressweges. While in 1. Part of the Einpressweges the press-fit contact can still be inserted into the opening relatively easily, reaches the holding section at the end of Einpressweges and there takes the insertion force defined.
- the opening in the opposite walls in this transverse direction (Z) in each case a groove (25) at least over the length (HBZx) of the holding section (HBZ) in the pressing direction (X), so that in this transverse direction (Z) has a hole width ( LBZ5) between these grooves (25) is formed, wherein the hole width (LBZ5) in the region of these grooves (25) by a predetermined amount is greater than the width (Z1) of the press-fit this transverse direction (Z).
- the pin tip 10 of the press-fit 1 is thus not pressed during pressing in this transverse direction Z.
- the grooves (25) also in the other transverse direction (Y) has a groove width (YN), which is also greater by a predetermined amount than the width (Y0) of the electrical contact region (10) of the press-fit (1), which the opening of the plastic housing is passed.
- FIGS. 3 and 4 show a 1. Embodiment, Figures 6 and 7, a second embodiment and Figures 5 and 2, a particularly preferred embodiment, which for both the 1. as well as the 2nd embodiment can be applied.
- one coordinate system is indicated for each of FIGS. 1-7, wherein the sections which are not visible in each case are indicated by dashed lines in the sections. All dimensions are also assignable by using a corresponding letter of the respective corresponding direction X, Y or Z.
- FIG. 1 one sees an electronic assembly in a sketchy exploded view consisting of a plastic housing 2, a plurality of press-fit contacts 1, a printed circuit board 3 with electronic components and a cover 4 in turn for closing the housing.
- the press-fit contacts 1 can be stamped sheet metal parts of constant thickness, in which case they are used in all figures as the Z direction.
- FIGS. 3A to 3C now show sections in the plane Y-Z, the X-position being respectively sketched by the reference lines between FIGS. 3A to 3C on FIG. 4 is a section in the X-Z plane.
- the hole width LBZ3 in the Z direction in this area is smaller by a predetermined amount than the width of the press-fit contact - that is, LBZ3 ⁇ Z1.
- the groove 25 is preferably arranged centrally in the transverse direction Y and has the opening in the holding section HBZ on both sides of this groove 25 holding zones with the hole width LBZ3 in the transverse direction Z, which are smaller by a predetermined amount than the width Z1 of the press-fit 1.
- the outer ßeren 4 corners of the press-fit 1 thus form a press fit in the Z direction against the wall of the opening in the plastic housing 2.
- the holding section (HBZ) is in this preferred embodiment in the pressing (X) seen at the end of Einpressweges, as from Seeing together Figures 3 and 4 can be seen, and extending in the pressing (X) only over a predetermined length (LHBZ) smaller the length of the entire opening in the pressing (X).
- the hole width in the Z direction is also not constant in the Y direction, but interrupted in this preferred embodiment in the central region by a groove 25 - therefore also the formulation in sections with respect.
- the holding portion HBZ is also not constant in the Y direction, but interrupted in this preferred embodiment in the central region by a groove 25 - therefore also the formulation in sections with respect.
- the opening thus has in each case a groove (25) in the opposite direction in the second transverse direction (Z) over its entire length in the press-in direction (X), so that a hole width (LBZ5) arises between these grooves (25) in the second transverse direction.
- a hole width (LBZ5) arises between these grooves (25) in the second transverse direction.
- the groove thus preferably has a width YN and hole width LBZ5, which is dimensioned such that the pin tip 10 can be guided with the dimensions Y0-Z1 shown in FIG. 3A, without damaging the sensitive galvanization of this pin tip.
- FIG. 4 shows the section through the opening in the plastic housing 2 with the pressed-in pressed-in press-fit contact 1 in the plane X-Z, that is to say straight perpendicular to the illustration selected in FIG.
- the course of the groove 25 is indicated by dashed lines and also to recognize the 3rd holding section HBZ with its location in the end of the press-in and its hole width LBZ3, while the earlier sections of the press-in, in Figure 4, the lower areas with the Hole width LBZ4 are slightly larger than the width Z1 of the press-fit 1.
- the hole width LBZ5 in the Z direction between the grooves 25 is even larger than the hole width LBZ4 in the outer corners and extends over the entire length of the opening. This is preferably used when relative high manufacturing tolerances for the width Z1 of the press-fit contact are conceivable and the PIN tip 10 should be particularly protected. However, if these special requirements are not met, an embodiment according to FIGS. 6 and 7 can also be used, which will be explained in more detail below with regard to the differences from FIGS. 3 and 4.
- the groove 25 is limited only to the length HBZx of the holding section HBZ and the hole width LBZ4 is provided in the groove, so that a rectangular cross-section results in the front region of the press-in path according to FIG. 6C.
- the dimensions of the opening in the Z direction which are now shown in connection with FIGS. 3 and 4 or 6 and 7, are deliberately selected independently of the dimensioning of the press-fit contact 1 in the Y direction.
- FIG. 5 now shows a section through the press-fit contact 1 introduced into the opening of the plastic housing 2 in the plane X-Y.
- the basic structure of the press-fit contact 1, starting with its tip and the 1, can be seen here.
- electrical contact region 10 with a width Y0 (ie in the first transverse direction Y).
- the first electrical contact region (10) preferably has in the first transverse direction (Y) a pin width (Y0) which is smaller than the smallest hole width (LBY1) of the holding section in the first transverse direction (Y).
- the base body 13 wherein this at the position X1 the 1st Holding lugs 1 1 with a resulting overall width Y1 and at the position X2 the second retaining lugs 12 having a resulting overall width Y2.
- the second electrical contact region 14 is in turn followed by the second electrical contact region 14.
- the second retaining lugs 12 are wider overall than the first. Hold tabs - so Y2> Y1. Since such a press-in contact is basically a self-negotiable unit and can be pressed into a conventional uniform opening in a plastic housing, a separate protection for this press-in contact is claimed.
- FIG. 5 and in particular also FIG. 2 likewise show, in this exemplary embodiment, a particularly preferred embodiment and shape of the plastic housing 2.
- the opening in the plastic housing is in this first embodiment.
- Transverse direction Y also not constant, but in a 1.
- FIGS. 2A to 2D respectively show sections through the opening in the plane Y-Z at different positions in the X direction, wherein the respective position is shown by the dashed arrows and with reference to FIG.
- the bold-lined edge corresponds to the edge of the opening of a respective position prior to pressing in the press-in contact, and in dashed lines the extent of the press-in contact is indicated in the figures.
- it comes through the press-fitting of the press-in contact to a certain deformation of the edge of the opening but this can not be represented in this sketchy representation suitable and therefore the press-fit contacts are indicated here only sketchy. It should be expressly pointed out here that no adjustments are made in the Z-direction in this embodiment in FIGS. 2A to 2D - these have already been explained with reference to FIGS. 3, 4 and 6/7.
- Figure 2A shows that the press-in contact (1) in the holding portion at this first position (X1) in the press-in (X) on opposite sides of the holding portion in each case the first retaining lugs (1 1), which relative to the main body of the holding portion (13) first oversize (Y1> LBY1) in a first transverse direction (Y) perpendicular to the press-in direction (X).
- FIG. 2B now shows the section in the region of the normal basic body 13 with its width Y3 smaller than the hole width LBY1.
- the press-fit contact (1) has in each case in the holding section at a second position (X2> X1) offset from the first in the press-in direction a second holding lug (12) again on opposite sides of the holding section, which has a second oversize relative to the main body of the holding section ( Y2) in the first transverse direction (Y). This is shown in section 2D.
- the second oversize is greater than the first oversize (Y2> Y1).
- the second holding portion (HBY2) in the first transverse direction (Y) also has in this preferred embodiment, a second hole width (LBY2 with a predetermined dimension (LBY2 ⁇ Y2) smaller than the second retaining lugs (12), wherein the second hole width (LBY2), however greater than the dimension (Y1) of the first retaining lugs (1 1) in this first transverse direction (Y), which is indicated by the auxiliary lines between Figures 2A to 2D.
- Such an opening with two different hole widths can be produced, for example, by two tools which form the opening from different directions, ie for example the first hole width and the first holding portion HBX1 with LBY1 from the upper side according to FIG. 5 - the second holding portion HBX2 the hole width LBY2 from below according to Figure 5, so the press-in X from.
- FIGS. 2A to 2D If one again considers the Z-direction in FIGS. 2A to 2D, in this embodiment it is initially assumed to be constant over the entire length of the opening.
- a further particularly preferred embodiment is the combination of the embodiments of Figures 3/4 or 6/7 with those in Figure 5/2, so an opening in the plastic housing 2, which in both Y direction according to FIGS. 2A to 2D have holding sections HBX1, HBX2 with different hole widths LBY1 and LBY2 as well as a third holding section HBZ, and a separation into several embodiments has been provided purely for the understanding of the different aspects, since the combination of both aspects into one figure makes the representation less easy would have been understandable.
- an electronic assembly is thus used with a corresponding plastic housing having at least one opening and at least one corresponding in each one of these openings.
- the opening preferably has holding sections HBX1, HBX2 with different hole widths LBY1 and LBY2 both in the Y direction and a third holding section HBZ in the Z direction, and one press-in contact with two pairs of holding lugs is used in each case.
- the first contact elements (1 1) of the press-fit (1) preferably form pins of a connector housing in the plastic housing (2) and the second contact elements (14) of the press-in contact are connected to an electrical circuit board (3) in the interior of the plastic housing.
