Definitions

  • the invention relates to a contact element for electrical plug connections, consisting of a stamped and bent part with a cross-sectionally U-shaped intermediate area with two side walls and a base wall connecting them, a line connection element at one end of the contact element and a contact pin projecting from the intermediate area at the other end of the contact element, wherein the contact pin is thicker than the other areas of the contact member.
  • Such contact members designed with a pin contact are generally - apart from being locked in a connector housing by means of an over-spring in certain areas of application - otherwise floating in the connector housing. It is therefore necessary to guide the pin contact area of the contact element for precise alignment with a socket contact. Since, on the one hand, an excess spring that may be used and, on the other hand, the guide length require a certain length of the pin contact, there is a risk of damage to the pin contact, for example due to bending and thus bending from the direction of insertion, in particular in rough workshop and assembly use. A certain amount of protection against such damage is achieved with contact elements in use, for. B. achieved in that a wire-shaped contact pin with a cross section of, for example, 0.63 x 0.63 mm is welded to a bent contact element made by punching from strip material and bent.
  • a contact member of the type mentioned is known from EP 0378 466 B1.
  • a metal plate which has two strips of different thickness, have contact organ the contact pin and the part of the U-shaped body adjoining it have a thickness which is greater than that of the remaining part of the contact element. In this way, the stability in the area of the connection to the U-shaped body can be improved.
  • the object of the invention is to achieve improved protection of the contact pin against damage, in particular against bending from the plug-in direction, in a simple manner in a contact element of the type mentioned at the beginning.
  • the contact pin is secured at the point at which it is most at risk of bending, namely in the region of its base connected to the U-shaped intermediate region, by positive locking with connecting elements of the intermediate region. Due to its form-fitting character, this securing can be achieved in a simple manner without additional effort at the same time during the manufacture of the contact element as a stamped and bent part, since the connecting elements provided for this purpose can also be stamped and bent during this manufacturing process.
  • the positive connection of the connecting elements with the contact pin reinforces and stiffens it in the area of its base. This stabilization expediently does not take place directly at the connection point of the contact pin at the intermediate region, but rather is offset somewhat from it in the direction of the free end of the contact pin.
  • the connecting elements are attached to a certain lever arm up to the point of the positive connection, which advantageously supports the contact pin laterally and further improves its rigidity.
  • connection of the connecting elements of the intermediate area with the contact pin Various possibilities are conceivable for the positive connection of the connecting elements of the intermediate area with the contact pin. So the positive connection z. B. brought about in that the connecting elements include the contact pin claw-like. Furthermore, it is also possible to form a guide slot for the contact pin, the guide slot being able to be formed by two extensions which lie laterally on the contact pin and are positively connected to the contact pin by stamping, clawing, shaping and / or bending. Finally, it is also possible to have an extension of the intermediate area engage in the contact pin from the side. Advantageous configurations of such connection options are specified in the subclaims.
  • the contact element 1 shown in the drawing in all of its embodiments according to FIGS. 1 to 7, is manufactured as a whole from a stamped and bent part and has a uniform, basic structure for all embodiments. Accordingly, the contact member 1 has a cross-sectionally U-shaped intermediate region 2 with two side walls 3, 4 and a base wall 5 connecting them, and a z. B. formed as a crimping element line connection element 6 with subsequent perforated plate 7 at one end of the contact member and a protruding from the intermediate area 2 contact pin 8 at the other end of the contact member.
  • the contact pin is in any case thicker than the other areas of the contact element, the material thickness z. B. is continuously 0.25 mm. In contrast, the z. B.
  • contact pin 8 in cross-section square contact pin 8 a thickness of about 0.6 x 0.6 mm, for example.
  • the contact pin 8 projecting forwardly from the intermediate region 2 on the contact side is reinforced in the region of its base connected to the intermediate region, so that it is secured against bending from the plugging direction.
  • both side walls 3, 4 of the U-shaped intermediate region 2 are formed on the contact side beyond the U-profile with strip-like extensions 9, 10 which run towards one another.
  • the extension 9 of the side wall 3 carries the contact pin 8 and is provided in the region of the transition into the contact pin with a lateral tab-like extension 11.
  • the extension 10 of the side wall 4 is slightly longer than the opposite extension 9 and is laterally in contact with the contact pin 8. In this area, the height of the side wall 10 corresponds approximately to the thickness of the contact pin.
  • the lateral tab-like extension 11 of the extension 9 is bent around the contact pin 8 and the opposite extension 10, so that it embraces them like a claw and presses against the contact pin.
  • the extensions 9, 10 with their lateral extension 11 or their free end 12 and the lateral extension 13 have a uniform material thickness which corresponds to that of the other areas of the contact element 1 and z. B. 0.25 mm.
  • both side walls 3, 4 of the U-shaped intermediate region 2 are also formed on the contact side beyond the U-profile with strip-like extensions 9, 10, which also converge again here.
  • the base wall 5 of the intermediate region 2 is also provided with a strip-like extension 15 beyond the U-profile, which extends beyond the connection of the contact pin 8, which in turn is carried by the extension 9, and is formed with a lateral, tab-like extension 16 which is directed transversely to the contact pin.
  • This approach 16 is angled by bends so that it includes the extension 10 claw-like and presses against the contact pin 8.
  • FIGS. 3 to 6 show other exemplary embodiments of a form-fitting connection of connecting elements of the intermediate area 2 of a contact element 1b to 1e with the contact pin 8.
  • the side wall 3 of the intermediate area 2 in turn has a contact pin 8 carrying the contact pin 8 extension 9 extending beyond the U-profile.
  • the base wall 5 of the intermediate area 2 is again formed with an extension 15 extending beyond the U-profile. These Extension is approximately from the point where the contact pin is connected to the extension 9 of the side wall 3 to thicker than the base wall, preferably as thick as the contact pin itself.
  • the extension 15 is formed with lugs in the form of two guide legs 21b, 22b and angled in an L-shape. These guide legs form a guide slot 23b between them for the contact pin 8 and lie laterally on the latter.
  • the positive connection of the guide legs 21b, 22b to the contact pin 8 is brought about at the free end of the guide legs.
  • the positive connection is formed by embossments 24 on sides facing one another at the free end 30b, 31b of the guide leg. These embossments are made in such a way that the contact pin on this stiffens slightly from its connection on the side wall 3 towards its free end, and thus is secured against bending.
  • Figures 4 to 6 show a contact element 1c to 1e with a guide slot for the contact pin 8 and a positive connection produced by clawing the connecting elements with the contact pin.
  • the side wall 3 is in turn formed with an extension 9 which carries the contact pin 8 and extends beyond the U-profile, the base wall 5 extending in the longitudinal direction of the contact element with an extension 15 also via the U-profile extends beyond.
  • the extension 15 is bent in an L-shape, with the one punched-out guide slot 23c lying between the guide legs 21c, 22c which laterally abuts the contact pin 8.
  • the free ends 30c, 31c of the guide legs are directed towards one another inward by tilting or twisting and thus encompass the contact pin in a form-fitting manner.
  • this causes the contact pin to be fixed in the lateral direction, this type of position fixation can be carried out very precisely and in a reproducible manner.
  • the position fixation in the vertical direction is brought about by a bead 32 in the extension 15 of the base wall 5 and / or by the tilting or twisting of the free ends 30c, 31c of the guide legs 21c, 22c.
  • the contact element 1d according to FIG. 5 largely corresponds to the contact element 1c according to FIG. 4, but differs in the design of the guide legs 21d, 22d forming the guide slot 23d of the extension 15 of the base wall 5 in that only the front guide leg 22d is angled at its free end 31d is so that it includes the contact pin 8.
  • the rear guide leg 21d is not angled, so that it only lies laterally against the contact pin with a straight course.
  • the rear guide leg 21d has approximately the same height as the front guide leg 22d.
  • the front guide leg 22d is produced by stamping, the rear guide leg 21d being bent up after the contact pin has been pivoted in.
  • the guide legs 21e and 22e enclosing the guide slot 23e between them are angled towards one another at their free end like the guide legs in FIG. 4, so that the two guide legs with their free end 30e, 31e formally enclose the contact pin 8.
  • the front guide leg 22e is produced by stamping, with the other, rear guide leg 21e being bent up in the manufacture as a stamped and bent part for positive connection after the contact pin 8 has been pivoted in.
  • the side wall 3 of the intermediate region 2 in the longitudinal direction of the contact element 1f has an extension 9f which is formed by an offset 40 and then extends again beyond the U profile and which is thicker away from the offset 40 than the other regions of the contact element 1f.
  • the extension 9f narrows in a wedge shape and merges into the contact pin, ie it has the thickness of the contact pin in this exemplary embodiment.
  • the extension 9f is provided with a slot-shaped recess 41.
  • the other side wall 4 of the intermediate region 2 has a straight extension 10f, which is aligned with the side wall 4 and also extends beyond the U-profile and laterally with the region 43 thicker away from the offset 40 on the offset extension 9f of the opposite side wall 3 is present.
  • the extension 10f merges into a narrow web 42. This web is bent in the direction of the cranked extension 9f and engages in its recess 41. In this way, stiffening of the contact pin is also achieved at a point slightly offset from the connection to the intermediate region 2. This offset point of the positive connection can also be clearly seen in the drawing in the embodiments according to FIGS. 3 to 6.
