B. another electric device connect to the circuit board to be able to.

to warranty high mating cycles and low contact resistance a silvering or gilding of the conductor tracks or printed circuit board pads required. Such an areawise silvering or gilding however, the circuit board is expensive. Furthermore, the electric Contacting of the conductor tracks or printed circuit board pads little space need, so that the corresponding devices are not too big which are in particular for portable or mobile devices applies.

in the The following is only the circuit board pads, the bottom However, the same is said to be analogous to printed conductors of a printed circuit board be valid.

From the US 5,160,275 is known an electrical direct connector for electrically contacting printed circuit boards. The direct plug has a resilient arm which moves resiliently when plugging the direct connector on a circuit board of this, whereby electrical contacts of the direct connector are also moved away from the circuit board. The spring arm resumes its original configuration when the direct connector is placed in its intended position on the circuit board, whereby the electrical contacts of the direct connector can contact conductor tracks of the circuit board.

This noble metal coating is preferably a gold plating or a silver plating. The noble metal coating is - if present - preferably at least at the first contact area 124 of the indirect plug 100 , However, it may additionally or instead the second contact area 122 of the indirect plug 100 be provided with the noble metal coating accordingly. In another embodiment of the invention, the contact spring 120 or the electrical contact 120 be completely provided with the noble metal coating. The extent to which such partial gold plating or silver plating is necessary depends on the later field of use of the indirect plug 100 from.

The contact spring 120 is designed such that their contact areas 122 . 124 at two longitudinal end portions of the contact spring facing away from each other 120 are provided. When inserting the contact spring 120 in the case 110 becomes the contact spring 120 first led by a circumferential housing section, which is on one side of the housing web 150 is formed. When advancing the contact spring 120 in the case 110 slides along an outwardly open portion of the housing 110 , but fitting inside of a housing section, to its final position. In the end position lies the contact spring 120 with its longitudinal edges on a respective partial circumferential wall of the housing 110 at. However, this housing section can also - to save space - missing, the longitudinal edges of the contact spring 120 preferably in grooves or an edge in the transverse direction in the housing 110 are guided.

Are the first contact areas 122 not with preload on the contact pads 210 On, so is a biasing force on the first contact areas 122 preferably via the mating connector 300 when plugging it on the indirect plug 100 applied. Furthermore - can - with biased contact springs 120 or with non-biased contact springs 120 - the contact springs 120 or their first contact areas 122 with the PCB pads 210 be soldered, pressed or jammed. Will these be on the PCB pads 210 soldered, this preferably takes place with an SMD or a reflow soldering process.

The recess 130 for the circuit board 200 is in its thickness dimension preferably the same size as the circuit board 200 in the corresponding area. The recess 130 However, it can also be thicker in the thickness dimension or, for a certain clamping effect, thinner. This also applies analogously to the length dimension. When laying out the indirect plug 100 or the circuit board 200 Care must be taken to ensure that adjacent to each other indirect connectors 100 together on the circuit board 200 are pluggable. This can be z. B. lead in one embodiment that the indirect plug 100 is not closed at one or both longitudinal ends (not shown in the drawing).

An electrical connection or an electrical contact of the printed circuit board 200 by means of the mating connector 300 finds according to the invention over the indirect connector 100 instead, by the mating connector 300 on the on the circuit board 200 sitting indirect plug 100 is plugged. In each case an electrical contact of the mating connector 300 contacts a second contact area 124 of the indirect plug 100 , The second contact area 124 is in electrically conductive connection with the first contact area 122 , which in turn in electrical contact with an electrical connection 210 the circuit board 200 stands.

As in 1c can be seen, is the first embodiment of the invention Indirect pin plug 100 only slightly larger than the PCB 200 in the area in which the indirect plug 100 on the circuit board 200 is plugged. In particular, on one side of the circuit board 200 closes a longitudinal end of the indirect plug 100 flush with the PCB 200 from. This is preferably via a recess 230 a circumferential side edge of the circuit board 200 realized.

The recess 130 is at least partially by a solid, solid wall 160 replaced, with this wall 160 together with the lying on her second contact areas 124 is generally thinner than the first embodiment with the cavity 130 and the second contact areas 124 , Furthermore, reference is made to a guide of the second contact areas 124 the contact springs 120 through one of the second contact areas 124 partially overlapping outer wall of the housing 110 dispensed; which is optional. In addition, when inserting the contact springs 120 in the case 110 this not all sides led, but mainly in each case by two parallel housing sections in the recess 140 held. The housing sections in this case preferably have a mutual overlap, in which an S-shaped transition section 126 the contact spring 120 is the first one 122 with the second contact area 124 combines. Laterally are the contact springs 120 led by a housing projection.

The contact spring 120 The second embodiment is also modified. Preferably lie in such an indirect connector 100 the first contact area 122 and the second contact area 124 the same contact spring 120 at the same level; dhu a, the distance between two directly opposite first contact areas 122 is the same as that between two directly opposite second contact areas 124 , This is done by a U-shaped section of the contact spring 120 realized, one leg of which is the S-shaped transition section. This is necessary so that one on a circuit board 200 pluggable mating connector also on the indirect connector 100 is pluggable.

The final position of the contact spring 120 is a good average AA 2 B to recognize. Here, the contact spring is supported 120 with a second contact area 124 opposite side on the central inner wall 160 of the housing 110 from.
