Definitions

• Press-in contacts of this type are known in the prior art and are used for Production of solderless electrical connections, the so-called press-in connection can correspond to DIN 41611, Part 5. Accordingly, the Generic press-in contact of the EE design because the press-in area of its the actual pressing pin forming shaft part is designed to be elastic, that is for the Press-fit connection necessary forces by deformation of the elastic shaft part and the printed circuit board receiving the press-in contact are applied - see Section 3.2.2 of DIN 41611, Part 5 -.
• a press-in contact is the entry known type known. With this press-in contact, the contact is in one Sleeve of a printed circuit board in the pressed-in state compared to others known press contacts improved by the slot opening on both of them Ends have the same parabolic shape while having one in the middle Has constriction. This will result in excessive, uneven deformation of the Counteracted slot opening limb, so that this after a The press-in process does not have to be adjusted.
• the invention has for its object to a generic press-in contact create, where there is too much hole wall deformation of the circuit board sleeve can be avoided.
• the slot opening is conical is formed and facing the contact spring or the contact pin End of the slot opening up to the area of the contact spring or the contact pin reaches in. Due to the length reaching into the contact spring or the contact pin the slot opening, the total elasticity of the press-in contact is increased because the elasticity of the slot opening also affects outside the hole in the circuit board, namely in the slot section extended into the contact pin.
• the conical configuration of the slot opening is such that that the reaching into the contact spring or the contact pin end of the Slot opening is formed wider than the end facing the connecting pin, while the center of the slot opening is fitted.
• the press-in contact does not become when it is pressed in damaged, because the tavern delimiting the slot opening - which on their Outside are convex - do not fall in the direction of the slot opening, so that lay them over their entire length on the perforated wall of the sleeve and thus also ensure good contact.
• An advantageous embodiment of the invention provides for the elasticity of the shaft part to be increased even further by the legs delimiting the slot opening their outsides have an embossing that extends from the press-in shoulder to extend to the area of the pin.
• press-in contacts according to the invention due to their good elasticity can have a significantly shorter overall length and thus Particularly suitable for printed circuit boards with a nominal thickness of 1.6 mm.
• a press-in contact 1 shown in FIG. 1 for pressing into a plated-through hole Hole in a printed circuit board has a central shaft part 2, to which the left over a press-in shoulder 3 connects a contact spring 4. To the front right end the shaft part 2 goes into a conical one that tapers towards the front Pin 5 receiving head 17 over.
• the shaft part 2 is with a conical slot opening 7 reaching into the area of the contact spring 4 provided, the upper and lower and front ends 8, 9 each have a has parabolic training.
• the end 9 facing the contact spring 4 and having a parabolic design comprehensive part 10 of the conical slot opening 7 is formed wider than that other, front part 11, which has a waist 12 approximately in the middle of the slot opening 7 has, then expanded again slightly and then towards the pin 5 rejuvenated.
• the parabolic end 9 of the slot opening facing the contact spring 4 extends into the contact spring 4 and is thus after a press-in process outside the circuit board.
• the other, narrower end 8 of the slot opening 7 is located on the other hand in the circuit board and ends at a distance 13 in the transition between the shaft part 2 and the connecting pin 5.
• the outer jacket of the press-in contact 1 has the slot opening 7 on both sides in the middle shaft part 2 each have a leg 14 and 15; these have a convex External shape and are each along their length between the press-in shoulder 3 and Area of the connecting pin 5 with a running out above the head piece 17 Embossing 16 provided. Due to the design and location of the slot opening 7 and the leg 14 and 15 with their stamping 16 becomes the entire press-in contact 1 more elastic, which on the one hand leads to the contact becoming nonetheless at the same time high holding forces can be pressed in with reduced force and on the other hand one Lattice wall deformation can be reduced. Nevertheless, there is still a good one Contact between the middle shaft part 2 and the plated-through hole 6 in the circuit board.
