Definitions
- the invention relates to an axially resilient press-fit contact pin with a metal body which has a press-fit spring and a pin-shaped section, the pin-shaped section being at least partially surrounded by an electrically conductive elastic element and the elastic element extending beyond the free end section of the pin-shaped section .
- German patent application DE 102006000959 A1 To produce electrical connections between two oppositely arranged printed circuit boards, it is known from the German patent application DE 102006000959 A1 to provide metal pins with press-fit springs formed on both end sections, which are pressed into both printed circuit boards.
- Zero force connectors which are also known as ZIF connectors, are often used, which receive and contact an end section of the foil conductor.
- ZIF connectors are relatively expensive, especially if only a few electrical connections have to be made.
- an axially resilient press-fit contact pin with the features of claim 1.
- the press-fit contact pin forms a press-fit spring that can be inserted into a metallized hole in a printed circuit board.
- the opposite second end section is designed to be axially resilient and electrically conductive, so that it can be applied elastically to a contact surface and can build up a certain contact pressure in the process.
- the second end section of the press-fit contact pin can be formed either by an elastomer body connected to the metal body of the press-fit contact pin or by a metal spring element, for example in the form of a helical spring.
- Figure 1 shows a first embodiment of a press-fit contact pin
- Figure 2 shows a second embodiment of a press-fit contact pin
- FIG. 3 shows a third exemplary embodiment of a press-fit contact pin
- FIG. 4 shows an application example of the first press-fit contact pin
- FIG. 5 shows an application example of the second press-fit contact pin
- FIG. 6 an application example of the third press-fit contact pin
- FIG. 7 shows an application example of a fourth press-fit contact pin
- FIG. 8 shows an application example of a fifth press-fit contact pin.
- FIG. 1 shows a first exemplary embodiment of an axially resilient press-fit contact pin 1 designed according to the invention.
- the press-fit contact pin 1 consists of a metal body 10, the first end section of which is formed by a press-fit spring 12 shaped as an eyelet.
- the second end section of the metal body 10 is designed as a pin-shaped section 14.
- the metal body 10 has a transverse web 16 between the first and the second end section.
- the pin-shaped section 14 is surrounded by an elastomer body 20 which completely encloses the pin-shaped section 14 and is preferably supported on the transverse web 16.
- the elastomer body 20 in particular projects beyond the free end of the pin-shaped section 14.
- the elastomer body 20 is preferably produced by overmolding the pin-shaped section 14 with an elastomer material. It is advantageous if the pin-shaped section 14 has a varying cross-sectional width in its longitudinal direction, for example in the form of a plurality of cross-sectional widenings, which results in a form-fitting connection between the metal body 10 and the elastomer body 20. By means of a suitably selected electrically conductive filler, the elastomer body 20 as a whole has good electrical conductivity.
- FIG. 1 An application example for the press-fit contact pin 1 shown in FIG. 1 is shown in FIG.
- the press-fit contact pin 1 is pressed here with its press-fit spring 12 into a metallized bore 42 in a rigid first printed circuit board 40.
- the conductor foil 50 is supported here by a section of a housing surface 60.
- the distance between the first circuit board 40 and the second circuit board 50 is set up or the overall axial length of the press-fit contact pin 1 is selected such that the elastomer body 20 is somewhat elastically compressed in the axial direction of the press-fit contact pin 1, so that the end face 22 of the elastomer body 20 with a certain contact pressure on contact surfaces on the second Circuit board 50 comes to the plant.
- the metallized bore 42 is connected to electrical or electronic components, which are also not shown, on the first printed circuit board 40 via conductor tracks (not shown). This results in an electrically conductive connection between the components on the first circuit board 40 and the contact surfaces of the second circuit board 50 via the press-fit spring 12, the metal body 10 and the electrically conductive elastomer body 20.
- the conductor foil 50 can thus form, for example, contact surfaces of a capacitive proximity sensor system under the housing surface 60, wherein the components of the associated evaluation electronics can be arranged on the first circuit board 40.
- FIG. 2 shows a second exemplary embodiment of a press-fit contact pin 2, which makes it clear that the shape of the elastomer body 20 'can be varied.
- the elastomer body 20 ‘here has two (or more than two) arms 24‘ or even a circular plate with an end face 22 ‘around it.
- the press-fit contact pin 2 can thus contact several points on the second printed circuit board 50 at the same time.
- FIG. 3 A third embodiment of an axially resilient press-fit contact pin 3 is shown in FIG.
- the elastic element 30 is formed here by a metal spring element and specifically as a helical spring.
- the pin-shaped section 14 'of the metal body 10' can hereby be designed as a simple cylindrical pin and does not require any sections with different cross-sectional widths.
- this can be welded or soldered to the transverse web 16 of the metal body 10 '.
- FIG. 6 shows an application example that functions analogously to FIGS. 4 and 5 with a press-fit contact pin 3 according to FIG. 3.
- FIG. 7 shows a further embodiment of a press-fit contact pin 4.
- the pin-shaped section 14 "of this press-fit contact pin 4 is folded or rolled up like a screw at its free end, thereby forming a cross-sectional widening 18", onto which an elastomer body 20 "can be injection-molded or otherwise attached.
- FIG. 8 shows a press-in contact pin 5, the pin-shaped section 14 '"of which has a fir tree-like cross-sectional widening 18'".
- the elastomer body 20 ′ ′′ is shaped here as a sleeve-like individual part which is preassembled with a housing body 62.
- the pin-shaped section 14 '" is inserted into the elastomer body 20'
- the fir tree-like cross-sectional broadening 18 '" digs like a barb on the inner walls of the elastomer body 20'”.
- a second printed circuit board 50 resting on the housing surface 60 is at the same time pressed against the end surface 22 ′ ′′ of the elastomer body 20 ′ ′′.
