Definitions

  • the subject of the present invention is a connection set between a motherboard and a card girl.
  • a set of connection between a motherboard and a daughterboard comprising a first connector comprising a first insulating body having first elements of contact whose first end is intended to be inserted into a motherboard as well as a second connector comprising a second insulating body having second contact elements including one first end is intended to cooperate with a second end of said contact elements correspondents and a second end of which is intended to be inserted in a daughter card, one side of connection of the first and second insulating body being opposite when the first and the second connector are connected.
  • connection set cannot be used only for at most two different card thicknesses girl.
  • circuit boards printed in different thicknesses for example 1.6 mm, 2.4 mm, and 3.2 mm. It is not currently possible to treat all possible cases with a single connector width, so that a standardization of models is not possible, hence disadvantages due to the manufacturing costs of connectors of different widths and storage of different types of connectors, which make little interesting the use of such connectors for high thickness printed circuits (3.2 mm in the example above).
  • Patent application EP-A-0 392 629 (Van Woensel) describes a example of connection assembly according to known art.
  • the subject of the invention is a set of connection of the aforementioned type making it possible to remedy the aforementioned drawback.
  • connection assembly is for this purpose characterized in that it comprises a wedging device for maintaining a distance determined between said connection faces of the first and the second insulating body so that a end of daughter board spaced first insulating body, in particular for keeping between the end of the daughter card and the installation plan of the motherboard, a distance equal to the standard dimension connectors of the prior art. Said end of the daughter card is thinned. This allows in particular to separate the second connector from the first connector (male) so that the first row of connection either in one part unthinned daughter card.
  • a lateral branch of the first insulating body has at a distal end a housing arranged on its face internal and intended to receive said end thinned, said distance being such that when the first and second connector are connected, an edge of the daughter card is located immediate proximity of said distal end.
  • a side face of the second insulating body then has means for holding said end thinned out daughter card.
  • the wedging device is also an element of foolproof.
  • a timing device may include a patch on at least one said insulating body and / or a projecting element forming an integral part of minus a so-called connection face.
  • An insulating body in particular the first body insulator, can have a central part and two lateral branches, the inner side of the part central unit constituting a said connection face.
  • Said unthinned edge can be located at immediate proximity of a second end of said connection elements. This keeps a fixation effective of the daughter card on the second body insulating which avoids the constraints on the second ends of the second connection elements.
  • a connection assembly has a male connector 3 having a body insulator 10 with a flattened U-shaped profile and a female connector 5 having a central body insulator 81.
  • the insulating body 10 includes a region central 11 and two lateral branches 12 and 13, the branch referenced 12 comprising means for foolproof.
  • the central region 11 has a plurality of contact elements 60 having a region 61 united with the central region 11, a region 63 forcibly inserted ("press-fit") into motherboard 1, and a male contact region 62 projecting from one side connection 31 of the central region 11.
  • the insulating central body 81 has contact elements 85 having a region 83 of female contact set back from one face of connection 41 and connection 88 with forced insertion ("press-fit") in a daughter card 2.
  • the elements 85 have a bent region 87 arranged in a zone insulating rear 89 of the insulating body 81.
  • a pawn of centering and holding 20 carried by a lateral face 82 of the insulating body 81 allows to solarize a end 25 of daughter card 2 with central body insulator 81.
  • a housing 16 located at the distal part 17 of branch 12 can receive the end of the pawn 20.
  • Figure 2 shows a set of connection which allows, according to the invention, the setting in artwork of a daughter card 6 of greater thickness.
  • One or more grooves 42 of the insulating body 81 allow to receive a shim of thickness 40.
  • An insert of thickness 40 added is housed removably in the central region 11 or in the central insulating body 81 so that when connectors 3 and 5 are assembled on faces 31 and 41 are spaced from each other. This allows offset the two connectors longitudinally assembled 3 and 5 so that the end 62 of daughter card 6 is spaced from distal end 53 of the arm 12. The position of the end 70 of the card girl remains unchanged.
  • the end 61 of the card girl 6 is thinned.
  • the proximal part 63 of the end 61 is extended by a connecting edge 62 with the unthinned end 66 of the daughter card 6.
  • This end 66 is located in the immediate vicinity of a row 89 of connections 88 and close to the end 53 of the arm 12.
  • the shim 40 thus allows to maintain the row 89 of contacts 88 in an unthinned region of the daughter card 6 and at closer to the distal end (here chamfered) of branch 12.
  • shim of reported thickness 40 also as a means of coding.
  • Keying elements are known, in particular from the request for European patent EP-A-0392629 (Van Woensel) cited above.
  • a such wedge is compatible with housing such as 42 (fig. 2 to 4).
  • An attached shim 40 makes it possible to adapt easily a standard connection set to all the thicknesses of the daughter card. Additionally, as noted above, it may or may not fulfill a function of keying, which gives great flexibility of use at low cost.
  • the shim 44 is an integral part of central region 11 (or of the insulating central body 81). In this case, the whole connection is in principle provided for a thickness maximum given from daughter card 6. It is however possible to also use a shim removable insert to adapt to other daughter card thicknesses 6.
