Definitions

  • the invention relates to a connector assembly for printed circuit boards according to the preamble of claim 1 or 9.
  • a connector assembly of this type also known as a so-called backplane connector, is described in US patent 4,655,518.
  • the first additional contacts are mounted in a sidewall of the first housing and made as a spring type contact.
  • the second additional contacts are mounted on one of the outwardly directed sidewalls of the second housing. Therefore, both the first and second additional contacts have to be especially manufactured contacts and have to be fixed in the first and second housing, respectively, in a special manner. These additional contacts are mounted in this special manner to provide current distribution contacts without increasing the dimensions of the connector assembly.
  • EP-A-0 347 097 is considered as comprised in the state of the art in accordance with article 54(3) and (4) EPC for the designated contracting states DE, FR, GB, IT and NL.
  • This document describes a connector assembly of this type, wherein the first additional contacts are male contacts of the standard type mounted in the base of the first housing in rows along the side walls of the housing and wherein the second additional contacts are arranged in rows in the second housing adjacent the outwardly directed side walls. These side walls are provided with slots for receiving the first additional contacts.
  • the connector assembly is characterized by the features of the characterising part of claims 1.A and 1.B.
  • the first additional contacts can be standard male contacts resulting in the possibility to assemble the first connector element by means of a selective pin insertion machine which inserts all male contacts including the additional contacts at desired locations in the printed circuit board, whereafter the first housing is pushed with its base on the contacts.
  • two or more contacts may be connected in parallel on the printed circuit board.
  • the pin insertion machine inserts the male contacts only whereas the additional contacts are inserted manually after mounting the first housing.
  • two or more additional contacts are part of one single element. Further two or more integral additional contacts can be provided with a common power connection end opposite of the contact region of the first housing.
  • the first connector element may be preassembled, so that the contacts are inserted in holes of the printed circuit board simultaneously.
  • the additional contacts may also be preassembled or may be manually inserted when the connector element is mounted on the printed circuit board.
  • the overall dimension of the connector assembly is not increased substantially.
  • first additional contacts if due to circumstances one or more of the first additional contacts are damaged, they can be removed easily and replaced by new contacts.
  • said first additional contacts extend along a longer distance from said base into said contact region than said male contacts.
  • different contact levels can be provided for the contacts so that for example first make/last break facilities for ground and power connections can be provided in a very convenient manner.
  • said male contacts and said first additional contacts are lengthened at the side opposite of the contact region of the first housing, a third housing of insulating material being provided including a base and two spaced upright sidewalls extending parallel to each other from said base and defining a second contact region therebetween, said lengthened male and first additional contacts projecting through said base into said second contact region thus providing a third connector element with at least one row of additional contacts close to one of its sidewalls.
  • the third connector element may cooperate with a fourth connector element with a fourth housing of insulating material including outwardly directed sidewalls adapted to be fitted between said spaced sidewalls of said third housing, and a plurality of parallel rows of fourth contacts and at least one row of fourth additional contacts, said fourth and fourth additional contacts each having contact portions for contacting the lengthened male and first additional contacts, respectively, when said fourth housing is received between the sidewalls of said third housing, at least one of the outwardly directed sidewalls of said fourth housing being provided with a plurality of slots for receiving said at least one row of lengthened first additional contacts.
  • the second and fourth connector elements are identical to each other.
  • said fourth connector element is made as a cable connector element for a shielded cable with a plurality of wires connected to said fourth with a metal cap with a passage for said cable adapted to contact the shield of the cable, wherein said at least one row of fourth additional contacts is connected to said metal cap thereby providing a continuous connection from said shield to said first additional contacts.
  • said first additional contacts are male contacts mounted in a row in the base of said first housing and said second housing comprises two parts each having outwardly directed sidewalls, one sidewall of one part facing one sidewall of the other part, wherein the printed circuit board to be connected to the contacts of the second housing is to be located above the facing sidewalls, the facing sidewalls of said two parts being provided with slots for receiving said row of first additional contacts, at least one of said parts being provided with said second additional contacts arranged in a row adjacent said sidewall provided with slots.
  • This embodiment of the invention may be preferred in high speed applications, as the printed circuit board connected to the contacts of the second housing is located more centrally with respect to the contacts of the second housing, whereby the length of the contacts, in particular the contacts at the outersides of the second housing, can be shorter.
  • said parts of said second housing are identical and said row of first additional contacts is mounted in the center of the base of the first housing.
  • a connector assembly 1 for connecting a printed circuit board 2 (daughter board) to a printed circuit board 3 (backplane).
  • the connector assembly 1 comprises a first connector element 4 connected to the backplane 3 and a second connector element 5 connected to the daughter board 2.
  • the first connector element 4 comprises a first housing 6 of insulating material including a base 7 and two spaced upright sidewalls 8 which extend parallel to each other from the base 7. A contact region 9 is defined between sidewalls 8. Further the first connector element 4 is provided with four rows of male signal contacts 10 which are press fit in the backplane 3 and extend through the base 7 into the contact region 9.
  • the first connector element 4 is further provided with two rows of first additional contacts 11 and 12 which rows of additional contacts 11, 12 are close to a corresponding sidewall 8.
  • the additional contacts 11, 12 are male contacts which are also press fit in the backplane 3 and extend through the base 7 into the contact region 9 of the housing 6 along a longer distance from the base 7 than the signal connector 10.
  • a further major advantage of the first connector element 4 is that this connector element can be assembled by a selective pin insertion machine which inserts the signal contacts 10 and additional contacts 11, 12 at the desired locations of the backplane 3 whereafter the housing 6 is pushed with its base 7 on the contacts 10-12.
  • the additional contacts 11, 12 can be manually inserted, especially when two or more additional contacts 11, 12 are integral.
  • cross section of the additional contacts 11, 12 may have any desired size and does not have to be equal to the cross section of the male contacts 10.
  • the second connector element 5 is provided with a second housing 13 of insulating material including outwardly directed sidewalls 14 adapted to be fitted between the sidewalls 8 of the first housing 6.
  • the second connector element 5 includes four rows of female signal contacts 15 having forked contact portions at their lower ends for contacting the male signal contacts 10 when the second housing 13 is inserted into the first housing 6.
  • the forked contact portions of the female contacts 15 lie within cavities 16 of the second housing 13.

  • the overall dimension of the connector assembly is not increased substantially by the provision of the rows of additional contacts.
  • the contacts 15, 17 are guided through a guide plate 21 for aligning the outer ends of these contacts with the holes of the daughter board 2 in which the outer ends of all contacts 15, 17 and 19 are for example press fit.
  • each three subsequent additional contacts 17 and 18 are integral as shown in fig. 2.
  • Fig. 3 shows a second embodiment of a first connector element 22 which mainly corresponds with the first connector element 4 of fig. 1.
  • three additional contacts 23 are also integral and provided with a common power connection end 24 as clearly shown in the perspective view of fig. 4.
  • the connector element 22 is identical to the connector element 4 and will not further be described. It will be clear that any desired design for power connection to the additional contacts can be chosen.
