Abstract
ABSTRACT
A make-before-break printed circuit board edge connector comprises a plurality of pairs of terminals arranged in a row with a housing having side walls snapped there over. The housing has an elongate slot therein for receiving an edge portion of a printed circuit board. Each of the terminals is staked to a support and has a main bowed portion extending upwardly into the housing with the concave side thereof facing an adjacent side wall of the housing and with the convex side thereof facing the convex side of the main bowed portion of the other terminal of the pair, the printed circuit board edge being insertable between these convex sides. Short circuiting contact arms, also bowed, are stamped from the main bowed portions. Each such contact arm is attached at its upper end to the top of the associated main bowed portion, is free at its lower end and extends downwardly with the convex side thereof facing and nearly or actually abutting the inner surface of the housing side wall adjacent to the main bowed portion from which the contact arm is stamped. The free ends of the contact arms touch each other below the convex surfaces of the main bowed portions of the pair of terminals to form a continuous electrical path through these terminals, which is not broken by the edge portion of the board until after the main contact portions mate with the printed conductors of the board.

Figure 2 is a sectional view taken on the lines II - II of Figure l;

Figure 6 is a side view of an electrical terminal of the connector prior to being assembled thereto; and Figure 7 is an elevational view of the terminal shown in Figure 5.
The connector comprises an elongate insulating housing 50 having a longitudinal slot 32 for receiving an edge portlon of a daughter printed circuit board 39, along an insertion path indicated by an arrow 33. Two rows of electrical terminals 10, arranged in opposed pairs of terminals ~n the housing 50 have posts 15 extending through apertures 57 in a mother printed circuit board 14 which is a part of the connector. Side walls 51 of the housing 50, .
.~ .
. ~0757~ 8941 between which the two rows of terminals 10 are disposed have through openi~gs 53 into which test probes (not shown) can he inserted to engage the terminals 10. Adjacent terminals 10 of each row are separated by partitions 73 formed integrally with the side walls 51 and each having a slot 58 for receiving the board 39, projections 37 on the partitions 73 serving to position the terminals 10 in the longitudinal direction of the housing 50.
As best shown in Figure 2, the post 15 of each terminal 10 has an enlarged portion 63 which has been force fitted into the corresponding aperture 57 to retain the terminal in the board 14. A support portion 19 of each terminal 10, extends from its portion 63 and has a stamped out tang 36 engaging the internal surface of the adjacent side wall 51 to position the portion 19 relative thereto.
Each portion 19 supports a first contact 38 of the terminal 10, the contacts 38 of each pair of opposed terminals 10 being bowed towards one another to present opposed contact surfaces 20 for making electrical contact with printed conductors 41 on the board 39. The contacts 38 are surmounted by tip portions 23 remote from the board 14 and : which normally engage pre-loading abutments 31 formed integrally with the housing 50 and which bound inward sides of the openings 53, in which the tip portions 23 lie. The housing 50 is secured to the board 14 by virtue of the frictional contact between the tangs 36 and the internal surfaces of the side walls 51 of the housing 50. Each : .

. -terminal 10 has a second contact in the form of an arm 25 stamped out from the first contact 38, the arms 25 of each pair of oppposed terminals 10 being bowed away from one another to present abutment surfaces 27, each of which engages the internal surface of the adjacent side wall 51.
Between the surfaces 27 and the portions 19, the arms 25, i.e. the second contacts of each pair of terminals 10, converge towards one another in the direction of the board 14 and normally meet at oppositely bowed contact surfaces 29 at their tips 28 (Figures 1, 2, 3 and 5). Between the surfaces 27 and the connections with the arms 25 with the contacts 38 in the vicinity of the portions 23, the arms 25 dlverge from one another in the direction of the board 14.
When, as shown in Figure 3, the printed circuit board 39 is inserted between the contact surfaces 20, the contact force between the contact surfaces 29 is increased as the arms 25 pivot about their abutment surfaces 27. A
continuous circuit path is maintained between the terminals 10 of each pair not only prior to the insertion of the edge portion of the printed circuit board 39 but also during its passage between the contact surfaces 20 as will be apparent from Figure 3. At this stage during the insertion of the board 39, the tip portions 23 of the contacts 38 which have been lifted from the abutments 31, engage the internal surfaces of the side walls 51 to enhance the contact forces between the board 39 and the surfaces 20.

~075788 8941 As the edge portion of the board 39 approaches its fully inserted position, as shown in Figure 4, towards the bottoms of the slots 5~, the contact surfaces 29 are separated by the board 39 and also make electrical contact with the printed conductors 41 thereon, so that each terminal 10 engages one of the conductors 41 at two spaced positions.
Failure o~ proper electrical contact, for example due to fouling, between one of the surfaces 20 and 29 of each terminal 10 and the corresponding conductor 41, is accordingly allowed for.
As the edge portion of the board 39 is withdrawn from the slot 32, the contact surfaces 29 of the arms 25 again engage one another, before the trailing edge o~ such edge portion has cleared the contact surfaces 20. The terminals 10 of each pair are therefore electrically connected to one another, excepting in the fully inserted, or the substantiall~ fully inserted, position of the edge portion of the board 39.
Opposed pairs of slots 74 are provided between the abutments 31 each such pair for receiving a keying plate (not shown) for reception in a slot (not shown) in the edge of the board 39. ~y selectively slotting the board 39 and by selectively positioning keying plates in the pairs of slots 74, it can be ensured that the board 39 can be mated ~5 only with a particular housing 50.
Figures 6 and 7 show a terminal 10 in its relaxed condition before its assembly to the housing 50.

It is an advantage of the connector that both the contacts, i.e. the contact 38 and the arm 25, axe comprised in a single terminal 10 which can readily be stamped and formed from a single piece of metal stock. A series of the terminals may be produced in strip form, the terminals of the strip being connected together in side by slde relationship by a carrier strip ~not shown) formed integrally with the tip portions 23 of the terminals, the terminals being severed from the carrier strip prior to their being assembled to the housing 50.

The connector comprises an elongate insulating housing 50 having a longitudinal slot 32 for receiving an edge portlon of a daughter printed circuit board 39, along an insertion path indicated by an arrow 33. Two rows of electrical terminals 10, arranged in opposed pairs of terminals ~n the housing 50 have posts 15 extending through apertures 57 in a mother printed circuit board 14 which is a part of the connector.

As best shown in Figure 2, the post 15 of each terminal 10 has an enlarged portion 63 which has been force fitted into the corresponding aperture 57 to retain the terminal in the board 14. A support portion 19 of each terminal 10, extends from its portion 63 and has a stamped out tang 36 engaging the internal surface of the adjacent side wall 51 to position the portion 19 relative thereto.
Each portion 19 supports a first contact 38 of the terminal 10, the contacts 38 of each pair of opposed terminals 10 being bowed towards one another to present opposed contact surfaces 20 for making electrical contact with printed conductors 41 on the board 39. The contacts 38 are surmounted by tip portions 23 remote from the board 14 and : which normally engage pre-loading abutments 31 formed integrally with the housing 50 and which bound inward sides of the openings 53, in which the tip portions 23 lie.

Between the surfaces 27 and the portions 19, the arms 25, i.e. the second contacts of each pair of terminals 10, converge towards one another in the direction of the board 14 and normally meet at oppositely bowed contact surfaces 29 at their tips 28 (Figures 1, 2, 3 and 5). Between the surfaces 27 and the connections with the arms 25 with the contacts 38 in the vicinity of the portions 23, the arms 25 dlverge from one another in the direction of the board 14.
When, as shown in Figure 3, the printed circuit board 39 is inserted between the contact surfaces 20, the contact force between the contact surfaces 29 is increased as the arms 25 pivot about their abutment surfaces 27. A
continuous circuit path is maintained between the terminals 10 of each pair not only prior to the insertion of the edge portion of the printed circuit board 39 but also during its passage between the contact surfaces 20 as will be apparent from Figure 3. At this stage during the insertion of the board 39, the tip portions 23 of the contacts 38 which have been lifted from the abutments 31, engage the internal surfaces of the side walls 51 to enhance the contact forces between the board 39 and the surfaces 20.
