Abstract
Description
- 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. In this known connector assembly, 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.
- It is an object of the invention to provide an improved connector assembly of the above-mentioned type, wherein standard contacts can be used at least partially for the additional contacts which standard contacts can be simply mounted in the corresponding housing.
- To this end, according to a first aspect of the invention the connector assembly is characterized by the features of the characterising part of claim 1.
- In this manner 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. In this case two or more contacts may be connected in parallel on the printed circuit board. Of course it is also possible that 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 can be integral in this case. 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.
- As an alternative 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.
- As the first additional contacts are received in the slots o fthe second housing, the overall dimension of the connector assembly is not increased substantially.
- Moreover, if due to circumstances one or more of the first additional contacts are damaged, they can be removed easily and replaced by new contacts.
- According to a favourable embodiment of the invention said first additional contacts extend along a longer distance from said base into said contact region than said male contacts. In this manner 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.
- According to a further favourable embodiment of the invention 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.
- Thereby high density connections can be provided with a backplane between the first and third connector elements.
- According to the invention 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.
- Preferably the second and fourth connector elements are identical to each other.
- In an alternative embodiment 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.
- According to a second aspect based upon the general inventive concept of the invention, 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.
- Preferably, 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.
- The invention will be further explained by reference to the drawings in which a plurality of embodiments of the connector assembly according to the invention are shown.

Thereby different contact levels for theadditional contacts 11, 12 with respect to each other and with respect to thesignal contacts 10 are possible, which results in first make/last break facilities for theseadditional contacts 11, 12 which are used for ground and power connection. Moreover, when due to circumstances one or more of theadditional contacts 11 , 12 are damaged, they can easily be removed and replaced by new contacts. - 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 thesignal contacts 10 andadditional contacts 11, 12 at the desired locations of thebackplane 3 whereafter thehousing 6 is pushed with itsbase 7 on the contacts 10-12. As mentioned above, theadditional contacts 11, 12 can be manually inserted, especially when two or moreadditional contacts 11, 12 are integral. It is further possible to provide apre-assembled connector element 4 which is mounted on thebackplane 3 by simultaneously inserting all contacts. In this case theadditional contacts 11, 12 can also be manually inserted afterwards. - It is noted that the cross section of the

Thesesidewalls 14 are further provided with slots 20 as more clearly shown in the perspective view of fig. 2. These slots 20 are provided for receiving theadditional contacts 11, 12. - Due to the described design of the connector assembly 1, the overall dimension of the connector assembly is not increased substantially by the provision of the rows of additional contacts.
