Definitions

  • the invention relates to a contact housing for assembling printed circuit boards according to the surface mounting technology, the so-called SMT method (Surface Mount Technologies), the contact housing having housing chambers into which contact elements made of stamped sheet metal parts are inserted, which form a plug contact and a printed circuit board contact, and one in one Have a hole in the printed circuit board.
  • SMT method Surface Mount Technologies
  • soldering leg soldering leg
  • the solder leg is soldered to a conductor track on one surface of the circuit board in the region of its free end and ensures the electrical contact of the contact element, which is arranged on the other surface of the circuit board, with an electrical element of the circuit board.
  • Soldering is a complex step.
  • solder joints are not necessarily contact-safe. There may be soldering defects. B. so-called cold solder joints, which are difficult to determine. Cold solder joints can be caused by production, but also by mechanical influences, e.g. B. by shock tion, occur.
  • the object of the invention is to eliminate the disadvantages of the soldered connections and to ensure electrical contacting which is safe due to the manufacture and which is not eliminated by mechanical shocks.
  • the one-piece contact element 1 made from a stamped sheet metal part has a square side wall 2, with an upper edge 3, a lower edge 4, and a front end edge 5 and a rear end edge 6.
  • a top wall 7 is bent at right angles from the top edge 3 of the side wall 2 and extends over the entire length of the top edge 3 and is approximately half as wide as the side wall 2.
  • saw tooth-shaped anchoring teeth 10 projecting outwards are arranged, the purpose of which is explained further below.
  • the anchoring teeth 10 are preferably only provided in the area from the front edge 11 of the ceiling wall 7 to the longitudinal center. Is between the rear edge 12 and the longitudinal center of the ceiling wall 7 introduced a downward, arcuate contact deflection 13 into the top wall 7, which extends transversely to the longitudinal extent of the top wall 7.
  • a fastening pin 15 is connected to the lower edge 4 of the side wall 2 and lies in the plane of the side wall and projects vertically downwards.
  • the fastening pin 15 is approximately as wide as the top wall 7 and approximately as long as the side wall 2 wide, or the end edge 5 of the side wall 2 is long.
  • the side edges of the fastening pin 15 are equipped with sawtooth-shaped anchoring teeth 16, the purpose of which is also only explained further below.
  • a contact spring arm 17 is connected to the lower edge 4, specifically with a base web 18 bent at right angles from the bottom edge 4 and parallel to the ceiling wall 7.
  • the width of the base web 18 and the contact spring arm 17 corresponds to the width of the ceiling wall 7.
  • the contact spring arm 17 extends from the spring arm base web 18 as a cut-in part initially with an upward curve 19 of approximately 180 degrees to the ceiling wall 7, the diameter of the curve 19 being less than the width of the side wall 2, and then with a straight one Spring arm web 20 obliquely to the deflection 13 of the ceiling wall 7 and then runs out in a short, downward arc 21.
  • the end region in front of the bend 21 preferably touches the deflection 13. From this spatial shape of the contact spring arm 17 and the course of the ceiling wall 7, an insertion funnel 22 results for e.g. B.
  • a square mating contact pin (not shown) which can be inserted into the space between the contact spring arm 17 and the top wall 7 from the end face 23 of the contact element 1 and can be contacted at the contact point between the deflection 13 and the start of the arc 21, the spring arm web 20 - due to the arch connection - freely down can dodge and press against the mating contact pin with its spring force.
  • the second contact point of the contact element 1 is connected between the fastening pin 15 and the rear end edge 6 on the side wall 2. It is a conductor track contact foot 24 which is formed by a contact foot base web 25 which is angled inwards at right angles from the lower edge 4 of the side wall 2 and a contact arm 26 which is connected to it and extends rearward beyond the rear end edge 6 of the side wall 2.
  • the base web 25 is approximately as wide as the spring arm base web 18.
  • the contact arm 26 is just as wide, which is angled slightly downward following the base web 25 and has an upwardly directed arch end piece 27 in the free end region, so that the lowest point of the contact foot 24 a contact line 28 is formed.
  • the contact arm 26 is approximately as long as the base web 25.
  • a housing 29 according to FIGS. 2-4 is expediently provided for the contact element 1.
  • It is an essentially cuboid plastic body with two end faces 30, 31, two side surfaces 32, 33, a ceiling surface 34 and a bottom surface 35.
  • Cuboid chambers 36 which are adapted to the contact element 1, are molded into the plastic body and form a side surface 32 and the bottom surface 35 are open, extend from the side surface 32 towards the side surface 33 and end shortly before the side surface 33.
  • the chambers 36 thus extend transversely to the longitudinal extent of the plastic body.
  • the length, width and height of the chambers 36 correspond to the length, width and height of a contact element 1.
  • a contact element 1 is inserted into a chamber 36 such that the top wall 7 of the contact element 1 rests on the top wall 37 of the chamber 36 and the front edge 5 abuts the end wall 38 of the chamber 36.
  • the anchoring teeth 10 have caught in the material of the side walls 39 of the chambers 36, so that the contact element 1 sits captively in the chamber 36 (not shown).
  • the fastening pin 15 protrudes downward out of the chamber 36 via the bottom surface 35 and the contact arm 26 projects beyond the side surface 32 to the outside and to the rear.
  • plug holes 40 are introduced into the plastic body going to the chambers 36, which open into the chambers 36 at the level of the insertion funnel 22 of the contact element 1, so that a mating contact pin (not shown) through a hole 40 to the contact point between deflection 13 and contact sheet 21 of the contact element 1 can be pushed.
  • the new contact housing 29 is fitted with contact elements 1 on a printed circuit board, the bottom surface 35 of the contact housing 29 being pressed onto the surface of the printed circuit board and for the mounting pins 15, slots or holes having a corresponding spatial shape in the printed circuit board into which the mounting pins are provided can be pressed and hooked with their anchoring teeth 16 in the plastic material of the slot walls, so that the contact housing 29 sits captively on the circuit board.
  • the contact arm 26 z. B. contacted a conductor track of the circuit board on which the contact arm presses due to its spring force.
  • bearing pins 41 can be provided which extend outward from the bottom surface 35 and at least fit into corresponding holes in the printed circuit board (not shown).
  • the contact housing according to the invention does not require soldering of the contacts. It can be placed on the side of the circuit board on which there are conductor tracks or similar contact elements, which is particularly advantageous if the other side of the circuit board is to be used for other purposes or if further conductor tracks for other electrical components are to be used.
