Definitions

  • the subject of the present invention is a connector intended for the connection between a first printed circuit board, called the motherboard, and a second board, arranged orthogonally to the first, often qualified as a daughter board, the two boards being provided with rows of ranges of contact arranged in staggered rows, said connector comprising an insulating body in which are formed a corridor for receiving the edge of the second card and passages for crossing flat electrical connection terminals between corresponding contacts of the two cards, each of the terminals having means hooking on the insulating body and a flexible arm intended to slide on the other card during the insertion thereof and to rely on a respective contact pad.
  • the staggered arrangement of the contact pads on the cards makes it possible to arrive at a very small pitch distribution pitch, which can go down to around 0.25 mm. But we then come up against the problem of making the insulating body for receiving the contacts.
  • the partitions intended to separate the contact terminals and to hold them laterally have a thickness so small that they frequently break and that it is even very difficult to produce the insulating body by molding of plastic material reinforced by fillers.
  • the present invention aims to provide a connector of the type defined above, meeting better than those previously known the requirements of practice, in particular in that its insulating body is much more easily achievable, even when the pitch of distribution of the contact terminals belonging to the same row is very small.
  • the invention provides a connector in which one contact terminal out of two comprises latching hooking means on the insulating body by insertion parallel to the direction of engagement of the second card in the connector, while the other terminals of contact can be snapped onto the insulating block by displacement in the direction orthogonal to the direction of engagement of the second card.
  • each contact terminal can be considered as having a base fitted with the hooking means and the elastic arm which projects inwards from the connector from the base and is intended to slide on one face of the second card.
  • the base generally has, for its part, a projection intended to bear on a respective contact pad of the first card.
  • the hooking means it is possible to arrange the terminal crossing passages so that the passages intended for one in two of the terminals (which will be termed odd terminals) are not aligned with those intended for the other terminals. (even terminals). Consequently, the partitions separating the contact terminals may have for the most part a thickness of the same order of magnitude as the pitch of distribution of the contact terminals, whereas the previous solutions generally led to giving these partitions a thickness substantially equal to the difference between the distribution pitch and the thickness of a terminal.
  • the terminal crossing passages intended to be inserted perpendicular to the second card will consist of parallel slots having a length slightly greater than that of the arm of the respective contact terminal, while the terminal crossing passages insertable parallel on the second card will be formed by slots parallel to each other or by windows made in the insulation and opening towards the first card.
  • the connector comprises a housing, of which only the insulating body 10 is shown.
  • This body has an elongated shape. It is intended to be fixed, by means not shown, on a first card 12, or motherboard, on which are arranged two sets of contact pads, each set having pads 14a and 14b arranged in staggered rows.
  • This connector is intended to receive the edge of a second card 16 or daughter card provided, near its edge, with two sets of contact 18a and 18b which are also staggered.
  • a passage 20 intended for the engagement of the card in the direction orthogonal to the arrow f.
  • Terminals 18a are intended to be inserted into the insulating block by displacement transversely to the direction of insertion of the second card 16.
  • the contact terminals 22b are provided to be inserted into the insulating body parallel to the direction of insertion of the second card 16 and in the opposite direction.
  • the invention is especially of interest when the pitch of distribution of the contact pads is small. At present, it is possible to obtain a pitch distribution pitch as low as 0.25 mm and for this we arrange these ranges in a staggered manner so that the line which connects the centers of the even ranges is separated from the line which connects the centers of the odd ranges with a distance d of about 2mm.
  • the terminals 22a and 22b shown in FIGS. 1 and 2 can both be considered to have a base 24 provided with means for attachment to the insulating body and an elastic arm 26 having a curved end portion, intended to rest on a contact pad 18a or 18b.
  • Each base has a projection or a lower bulge intended to bear against a corresponding contact pad 14a or 14b.
  • the passages for crossing the flat terminals include two windows 28 extending all along the insulating body 10, without intermediate partitions between the terminals, which is without disadvantage.
  • the bases which must be guided, are not in the window area.
  • Terminals odd contact contacts have a base intended to come to bear against bridges 30 constituting partitions between the bases of the even terminals 22b.
  • the base is provided with two elastic tabs 32 each terminated by a hooking spout, intended to frame the bridge 30 and to snap onto it.
  • the assembly constituted by the wide part of the base and the legs 32 constitutes a fork which slides on the bridge 30 during the insertion of the contact terminal and comes to hang on the bridge.
  • each pair contact terminal also constitutes a fork having a single latching finger 32.
  • the fork comes to frame a bridge 34 and click on him.
  • This bridge constitutes a partition between adjacent odd contact terminals 22b and for guiding these terminals.
  • the partitions can have a thickness of the same order of magnitude as the distribution pitch, that is to say approximately 0.25 mm: the molding of insulating body whose thin partitions have this thickness does not pose any problem. particular.
  • each odd contact terminal 22b also constitutes a fork with the hooking lug 32 provided with a terminal spout. This beak snaps onto a shoulder formed in a central rib 36 extending all along the corridor.
  • Each terminal 22b can be engaged in the insulating body 10 by pushing it upwards in FIG. 4.
  • the paired contact terminals 22a also have an elastic arm 26 and a base 24.
  • the base has a wide part forming a support square which rests on the bottom and on a side of the insulating body 10. The vertical part of this base is guided by partitions with the following even terminals.
  • the elastic tab 32 snaps onto the internal face of the insulating body 10 when the contact terminal 22a is inserted by passing the contact arm 26 through the corresponding slot 38 which constitutes a through passage.
  • the connector housing can have the constitution shown in FIG. 6 and include the insulating body 10 and a block 40.
  • the body 10 shown is designed to be fixed to the card 12 (FIGS. 4 and 5) by screws 42.
  • the block 40 is provided to cover the insulating body 10.
  • a slot (not visible in FIG. 6) is provided there to allow the card 16 to pass and guide.
  • the invention is susceptible of many other variants as well. It is applicable both to 16 double-sided daughter cards of the kind shown in the figures and to single-sided cards.
  • the insulating body 10 can be mounted in any of the connectors commonly used to connect one or more daughter cards to a motherboard.
