Definitions

  • the invention relates to a flat plug contact element for electrical plug connections, consisting of a stamped and bent part with a line connection element at one end of the contact element, with an intermediate area following the line connection element and bent into a box with a rectangular cross section, with two side walls, one connecting them Bottom wall and a roof wall, and with a contact knife protruding from the intermediate area, thicker than the other areas and consisting of two halves at the other end of the contact element.
  • Such contact organs are often used as flat plugs in automotive connectors where they are exposed to harsh operating conditions.
  • Such contact members are often designed with a contact knife, for example of 2.8 x 0.63 mm or 5.2 x 0.63 mm, and must have high mechanical stability, for example, because of the required sure-footedness.
  • the intermediate area of such a contact element that is to say the area between the contact knife and the line connection element, is often designed as a rectangular, closed box.
  • the contact knife itself must have a certain stability for mechanical and electrical reasons; it is therefore usually designed with twice the material thickness of the other areas of the contact element.
  • EP 0 572 874 B1 discloses a contact element of the type mentioned at the outset, which is produced from a stamped and bent part and has a box-shaped intermediate region which is rectangular in cross section and to which a contact knife of double material thickness is connected.
  • the contact knife is formed from two halves, which are attached as extensions to the side walls of the intermediate area and by bending up the side walls and folding them sideways, form a complete contact knife of double material thickness.
  • the processing of the intermediate area and the contact knife results in a relatively large division of the sheet metal stampings lying side by side in a sheet metal strip.
  • a flat plug contact member of the type mentioned in which the initial stamped and bent part initially has a uniform thickness, which corresponds to the final thickness of the contact knife, which in the connection area and in the intermediate area z. B. is reduced by a milling tool to about half the material thickness of the starting material.
  • an additional machining operation is therefore provided to produce the material thickness provided in the individual areas.
  • the contact knife is here connected to the base wall of the intermediate area, which in addition to the base wall has the two side walls and the top wall.
  • the primary object of the invention is to achieve a more rational manufacture of the contact element in the case of a flat plug contact element of the type mentioned at the outset with a box-shaped intermediate region and a contact knife thicker than the other regions, in addition to the usual requirements for such contact elements, in particular with regard to mechanical stability to allow a stamped and bent part.
  • the contact knife halves are aligned with one another in the longitudinal direction, the complete contact knife having twice the thickness of the material being formed by folding transversely to the longitudinal direction and bending back the second knife half by 180 ° over the first knife half. It also differs from known ones
  • Flach ⁇ teck contact organs of the type mentioned still provided the roof wall of the intermediate area in the longitudinal direction in alignment on the second half of the knife, so that compared to known contact organs overall a longer but significantly narrower starting part for the manufacture of the contact organ results in a stamping and bending process and thus despite the training of the contact element with a box shape, smaller divisions can be achieved on a metal strip. Overall, better material utilization can thus be achieved despite a wider sheet metal strip. Since, together with the bending process for the contact knife, the roof wall also comes between the two side walls of the intermediate area, the box shape of the intermediate area can also be formed in a simple manner, so that overall a more rational production of the contact element from a stamped and bent part is made possible.
  • the design of the contact element according to the invention is advantageous due to the direct connection between the roof wall of the intermediate area and the contact knife and the connection options that arise between the side walls of the intermediate area and the roof wall, also with regard to the mechanical stability of the contact element that can be achieved.
  • Another advantage of the contact organ according to the invention nes can be seen in the fact that the two knife halves are aligned one behind the other by their arrangement in the longitudinal direction so that they remain connected after folding at the tip of the contact knife, so that this z. B. cannot be separated during the plugging process.
  • the first half of the knife is connected to the bottom wall and the roof wall to the second half of the knife by an intermediate piece, the length of which is selected such that after an offset of the first intermediate piece of the Bottom wall and the second intermediate piece of the second knife half, the completely folded contact knife is located centrally with respect to the height of the box-shaped intermediate area.
  • Simple mechanical connection options between the roof wall and the side walls of the intermediate area result if the two side walls of the intermediate area are provided on the free longitudinal edges with rags for support and / or connection for the roof wall. It is expedient if the side walls of the intermediate area are each provided with three tabs, the two outer tabs are each provided for supporting the underside of the roof wall, and the middle tab in each case is clamped to the outer top of the roof wall.
  • FIG. 1 shows a flat plug contact element in a perspective view, Figure 2,
  • Figure 5 is a development of stamped and bent parts from which contact members are made.
  • the contact element 1 shown in FIGS. 1 to 4 is made from a stamped and bent part 2, for example from a highly conductive Cu alloy, which - as the development of two stamped and bent parts 2 hanging from a sheet metal strip 18 in FIG. 5 best shows - a connection area A. at one end has an intermediate area Z following the connection area and a contact area K projecting therefrom at the other end.
  • the stamped and bent part 2 has a uniform thickness, for. B. from about 0.3 mm to about 0.4 mm.
  • a line connection element is formed by bending.
  • B. is designed as a crimp element 4, but instead may also consist of at least one insulation displacement element.
  • the intermediate area Z following the lateral incisions 5 of the connection area A has a bottom wall 6, two side walls 7 and 8, which are bent at the bending lines B1 and B2 into a channel which is initially U-shaped in cross section, and a roof wall 9, to which later is discussed in more detail.
  • This roof wall is arranged so that the intermediate area Z has a closed box shape with a rectangular cross section.
  • the contact element of the flat plug contact element provided in the contact area K is formed by a contact knife 10 consisting of two halves 10a, 10b and - as described below - has twice the material thickness in the final state, that is to say a thickness of, for example, 0.63 mm or 0.8 mm.
  • the first half 10a of the contact knife 10 is short first intermediate piece 3a with a width of z. B. 2.8 or 5.2 mm tied to the bottom wall 6 of the intermediate area Z.
  • the knife half 10a runs in the longitudinal direction up to a bending or folding line B3, in front of which the side edges of the knife half are formed with bevels 11.
  • the second knife half 10b adjoins the first knife half 10a in alignment in the longitudinal direction, with corresponding bevels 11 in the area starting from the bending line B3 on the side edges like the first knife half, that is to say in mirror image with respect to the bending line B3.
  • the second knife half 10b is of course the same length as the first knife half 10a.
  • the previously mentioned roof wall 9 of the intermediate region Z is connected via a second intermediate piece 3b corresponding in length to the first intermediate piece 3a.
  • This roof wall 9 is somewhat wider than the knife halves 10a and 10b and is designed with a cut-out, resilient latching hook 22 for latching or primary securing when the contact member is arranged in a housing.
  • the first half of the knife is bent from the bottom wall 6 via a crank 12 of the first intermediate piece 3a.
  • the complete contact knife 10 is then formed at the junction of the two knife halves 10a and 10b, i.e. at the bending line B3, by folding transversely to the longitudinal direction of the knife halves and by bending the second knife half 10b back through 180 ° over the first knife half 10a, ie the two knife halves 10a and 10b are now brought together to coincide, the bevels 11 forming the knife tip.
  • the roof wall 9 is also bent back in the direction of the intermediate region Z and bent over by a crank 12 of the second intermediate piece 3b from the second knife half 10b, so that the roof wall 9 now between the two side walls 7, 8 of the Between rule area Z arrives and is located in the area of the upper free longitudinal edges 13, 14 of the side walls.
  • the intermediate area Z now has the shape of a box with a rectangular cross-section, on which the completely folded contact knife 10 projects centrally due to a corresponding, ie in each case the same length of the intermediate pieces 3a and 3b with respect to the height h of the intermediate area.
  • the two side walls - as the development in FIG. 5 shows particularly clearly - are formed on their free longitudinal edges 13, 14 with tabs 15 and 16, respectively, which are laterally spaced apart by cutouts 17.
  • three tabs 15a, 15b, 15c and 16a, 16b, 16c are provided, the two outer tabs 15a, 15c and 16a, 16c each serving to support the underside of the roof wall 9 and the middle one Tabs 15b and 16b on the outer top of the roof wall is clamped to this
  • the roof wall parts 9a and 9b located on the side of the latching hook 22 are each formed with an indentation 9c and 9d in the area of the middle tabs 15b and 16b of the side walls 7, 8.
  • the roof wall 9 is expediently non-detachably connected to the side walls 7, 8 of the intermediate area Z, in view of the required sure-footedness of such contact members and in view of better power transmission properties in the area of the support tabs 15a, 15c and 16a, 16c.
  • at least one of the support tabs, e.g. B. the tab 15c in Figure 2 is designed such that it extends into the region of the locking hook 22. This overlap forms an overbend protection for the locking hook.
  • the intermediate area Z is still torn out of the bottom wall 6 by 90 ° Polarization web 21 is formed and its side walls 7, 8 are provided on their front edge with inwardly inclined tabs 23, while the rear edge 19 of the side walls 7, 8 together with the rear edge 20 of the roof wall 9 is a system for a secondary fuse in the arrangement of the contact element in forms a housing.
  • the two knife halves 10a and 10b can additionally be mechanically connected to one another in the fully folded state. This connection is then advantageously carried out at two points 24, 25 in the region of the two ends of the contact knife 10, for. B. by two 90 ° directed impressions or so-called clinch connections in the region of the central axis of the contact knife 10.

Abstract

L'invention concerne un organe de contact (1) constitué d'une pièce estampée et pliée (2) qui porte un élément de raccordement (4), une zone intermédiaire (Z) en forme de boîte et une lame de contact (10) faisant saillie à partir de cette zone intermédiaire. Les demi-lames (10a, 10b) et la paroi supérieure (9) de la zone intermédiaire sont, lorsque l'on regarde la pièce estampée pliée en projection développée, alignée l'une derrière l'autre, sur la paroi inférieure (6) de la zone intermédiaire. On obtient ainsi un écartement aussi faible que possible entre des pièces estampées pliées, sur une bande de tôle. La lame de contact (10) est formée par rapprochement des demi-lames (10a, 10b), c'est-à-dire par pliage au niveau d'une ligne de pliage transversale (B3), ce qui permet d'obtenir une double épaisseur de matériau, la paroi supérieure (9) prenant sa place entre les parois latérales (7, 8) de la zone intermédiaire (Z) et formant ainsi une boîte rectangulaire fermée d'une grande stabilité.
