Definitions

  • the invention relates to a contact device with at least one connection contact, a contact clamping device and a contact receiving device.
  • the invention also relates to a printed circuit board connection device with such a contact device and a plug contact, the plug contact being guided through the contact receiving device and held in the contact clamping device and the connection contacts being connected to a printed circuit board element.
  • the invention also relates to a method for producing a contact device.
  • Contact devices are, inter alia, from the CN 200 956 439 Y , EP 1 341 264 A2 and DE 20 2009 010 426 U1 known.
  • Connection contacts with struts, contact surfaces and contact plates are formed from a metal foil.
  • the struts are bent in such a way that the contact plates resiliently form a contact-making device.
  • At least one terminal contact is connected to the struts.
  • a plug-in contact can be inserted into the contact-receiving device.
  • the connection contact enables connection to a printed circuit board.
  • WO 2005 079 127 A1 discloses an electrical assembly with an electrically conductive contact pin for pressing into an opening in a printed circuit board.
  • the opening in the printed circuit board has predetermined dimensions and the contact pin has a defined oversize at least in a partial area for forming a press connection.
  • the inserted length of the contact pin is greater than the depth of the circuit board opening.
  • the inserted contact pin rests with an edge area on the printed circuit board and makes contact in the pressing area with the contact zone located there, which is preferably cold-welded in a gas-tight manner and flow-soldered on the opposite side to the contact zone there.
  • connection to a circuit board will be like that WO 2005 096 447 A1 , U.S. 2005 0176 267 A1 , DE 10 2009 025 113 A1 or. DE 10 2005 021 568 A1 describe, made by means of a press-in pin.
  • the object is achieved by the contact device having the features of claim 1.
  • Advantageous embodiments are described in the dependent claims.
  • a side plate with connection contacts is arranged on one narrow side of the contact plate, and a further side plate with further connection contacts is arranged on the opposite narrow side of the contact plate.
  • Both side plates can be folded up with their connection contacts and delimit the connection recess.
  • the connection recess can be adapted to the shape of the plug contact and have different geometric shapes. One of these shapes can be that of a rectangle.
  • the side plates can be folded down at different angles relative to the contact plate. One of these angles can be 90°. These right angles ensure good power transmission when connecting the terminal contacts.
  • the terminal contacts can be arranged on the opposite long sides of the contact plate. They are inclined towards the connection recess and thus ensure good and secure contact with the plug-in contact.
  • the contact plate, the side plates with the connection contacts and the terminal contacts can be made from sheet metal, from an electrically conductive material, in particular copper, brass, aluminum, CuNiSi or the like. With a thickness between 0.4 and 1.5 mm and more.

  • First terminal contacts can be essentially S-shaped. They allow easy insertion of the terminal contact and make it difficult to pull it out.
  • Second terminal contacts can be essentially S-shaped. They allow the connection contact to be easily inserted and pulled out. This creates an easily detachable connection.
  • connection contacts can be in the form of press-in contacts, solder contacts or the like. Which embodiment is used depends on the specific conditions of use.

  • the press-in contacts 4.1, ... cannot only be directed vertically upwards, as shown. Rather, they can be angled in all directions, ie pointing to the side, inward, downward or the like.
  • the press-in contacts 4.1, .. can also have different lengths and diameters.
  • soldering contacts can also be used.
  • connection recess 3 On one long side of the contact plate 2 three terminal contacts 7.1, 7.2, 7.3 are arranged.

A thickness of up to 2.5 mm is conceivable, i.e. doubling the previously workable thickness of 1.2 mm with approximately the same dimensions for contact length I, contact width b and contact height h of the electronic contact. In addition, the high-current application improves significantly.

  • the terminal contact is bent in an arc from the contact plate and then in a vertical straight part to pass. This is followed by a 180° bend via a curve, in order to be angled slightly inwards at the end.
  • terminal contacts 107.1 In contrast to the terminal contacts 7.1, ... they have releasing properties. This means that the plug contact can be plugged in and pulled out as often as you like.
