Definitions

  • the invention relates to a pin-shaped contact element for fastening in printed circuit board bores, preferably in metallized bores, with a fastening section which has two mutually movable, parallel side parts and the side parts are connected to one another by a spring-elastic, wavy connecting web.
  • the limbs of the web should preferably have an angle of approximately 45 ° to the side parts and enclose an angle of approximately 90 ° to one another.
  • the connecting web between the two side parts can also be W-shaped.
  • the connection (introduction) of the connecting web to the side parts is carried out on the end face on the inner surface of the side parts.
  • the known press-in pin is, on the whole, satisfactorily suitable for being pressed once into a metallized circuit board bore.
  • severe damage to the metallization often occurs by cutting into the edges, unless extremely tightly tolerated and coordinated bore and pin dimensions are provided, which are outside of economically producible and generally for such Contact pins and PCB holes are within the usual tolerances.
  • the present invention is based on the object to provide a pin-shaped contact element for pressing into metallized printed circuit board holes, the tolerance limits with regard to the hole and press-fit area dimensions are substantially increased, which has a uniform contact pressure of all contacting edges in the hole and in which the Possibility is given to press contact elements into the bore without damage and substantial irreversible deformation of the bore wall and also to be able to remove them again from the bore in order, for. B. for repair purposes to enable the problem-free exchange of contact elements.
  • a contact element inserted into the same hole should also have a vibration-proof, gas-tight long-term contact, making use of the tolerances that are common today in production technology.
  • a pin-shaped contact element with a highly elastic press-in area has been created, which can be used in printed circuit board bores with widely differing diameters, it also ensuring that the bore metallization is not damaged in an inadmissible manner or is deformed so that an exchange of possibly defective contact elements is easily possible.
  • vibration-proof, gas-tight contacting between the contact element and metallization is achieved via four contact zones.
  • the highly elastic press-in area not only makes it possible to remove contact elements from a hole and press a new contact element into the same hole, but it is also possible, if appropriate, to reinsert a contact element that was previously used in a hole.
  • Another advantage of the invention is that the press-in forces required to press in such a contact element are exerted are extremely low, which in turn gives the possibility of pressing a large number of contact elements together with a corresponding associated insulating body into a printed circuit board.
  • the fastening section is adjoined at the top in general by a pin, socket or fork contact, not shown here, as well as mounting and fastening devices for an insulating body.
  • the contact element ends in a chamfered insertion tip or continues in the form of a rectangular connection post for wire winding technology. This area is also not shown here in order to limit the drawings to the essentials of the invention, namely the fastening section 1.
  • the fastening section can be produced in a particularly advantageous manner from round as well as rectangular starting material.
  • the side parts are shaped in one stamping process.
  • the fastening section with the insertion bevel 4 merges into the lower contact element region 5.
  • the outer edges 8 of the side parts 3 come into intimate contact with the bore wall and the elastic suspension of the connecting web 9 in connection with a certain elasticity of the transitions of the side parts in the upper or lower contact element area causes a constant pressure force of the edges against the bore wall.
  • Contact elements of this type can be used in bores with widely differing diameters, in each case reliable holding and contacting with the metallized bore walls being achieved.
  • the bores are those whose different diameters are due, on the one hand, to manufacturing tolerances and, on the other hand, to the different structure of the bore metallization. These diameter tolerances are usually in the range of + 5% ... + 8% without having to use particularly complex and costly production processes.
  • a fastening section 1 of a contact element is shown, which can be produced in a particularly advantageous manner from round as well as rectangular starting material.
  • an enlarged image scale was chosen in FIGS. 2 and 3.
  • the material of the contact pin of this embodiment is provided in the fastening section 1 with opposing impressions, so that on the one hand the parallel side parts 3 are formed and on the other hand a wavy connecting web 9 is formed here between the two side parts.
  • the connecting web has three bends (deflections) 10, the “neutral fiber” 11 merging into the respective side part 3 at an angle a of 45 °.
  • the bends are designed in such a way that tangents applied to the neutral fiber form an angle ⁇ of 90 °.
  • the connecting web is integrally formed on the side surface of the respective side part, whereby the parallelism of the side parts to one another is favorably influenced when the contact pin is pressed into a bore and a largely uniform edge pressure of all contact edges 8 in the bore is achieved.
  • the transitions from the material of the connecting web to the respective side part are provided with curves 12, 12 ', since such a transition can be produced more economically on the one hand than a sharp-edged transition and, on the other hand, such a smooth transition has a favorable effect on the angular stability when pressed in out.
  • the thickness corresponds to b of the connecting web about 1/3 of the thickness a of the side parts, has the self-resilient during lateral compression properties. Furthermore, the outer edges 8 of the side webs 3, which come into contact with the bore wall when inserted, are rounded in order to largely avoid damage to the bore wall.
  • FIG. 3 shows a modified fastening section of a contact element in cross section.
  • the essential dimensions and dimensions correspond to the fastening section shown in FIG. 2 and explained in more detail above.
  • the “neutral fiber” 11 of the connecting web 9 when entering the respective Se ' ' Part 3 runs at right angles to this.
  • the tangents of the bends 10 form an angle y of 45 ° in each case.
  • FIG. 4 shows the use of a contact element according to a fastening section.
  • Fig. 2 shown in a circuit board bore 13. 4 shows the use in a bore with a maximum diameter, while FIG. 5 shows the use in a bore with a minimum diameter.
  • the wall of the bore 13 of the circuit board 14 is provided with a copper metallization 15 and a tin support 16.
  • the edges 8 of the side parts 3 come into intimate contact with the metallization of the bore wall when the fastening section is pressed in, the edges 8 penetrating into the relatively soft tin layer 16.
  • the tin material 17 pushed away is closely attached to the contact areas of the side parts and guarantees a gas-tight seal of the contact point to the surrounding atmosphere.
  • the wavy, resilient connecting web 9 has in this case (largest bore diameter) been compressed only slightly, but care has been taken by appropriate design of the initial dimensions according to FIG. 2 that the spring force of the connecting web is sufficient to ensure perfect long-term contact of the side parts to achieve with the bore wall.
  • FIG. 5 shows, for example, how the spring-elastic connecting web 9 deforms when the fastening section is pressed into a printed circuit board bore 13 with a minimal diameter. It can be seen that the corrugated connecting web is largely compressed here, the side parts 3 being pressed against the bore wall with greater force. Although a certain small amount of irreversible, plastic deformation can occur during the extensive deformation of the connecting web, a large amount of resilient deformation remains, which ensures the resilient pressing of the edges of the side parts onto the bore wall. Due to the rounding of the edges 8 of the side parts, it is also ensured here that the edges do not damage the metallization and only deform to a small extent.
