The auxiliary legs 9 may be formed in a number of manners. It may be formed
by bending a selected extension 9 which is segregated from and punched out of the
main engagement leg 6 (Figure 7). When formed, the lateral distance between the
outer surfaces 9b of the opposite auxiliary legs 9 is equal to the lateral distance U
(Figure 6) between the inner surfaces 4b of the connector sidewalls 4. In order to
facilitate the insertion of the connector sidewalls 4 into the intervening space 12, each
auxiliary leg 9 may be equipped with an inwardly-bent end 9a which reduces the
likelihood of snagging the placement cover auxiliary support legs 9 on the inner
surfaces 4b of the connector sidewalls 4.
Ikesugi teaches (column 5, line 65, to column 6, line 20) that
[i]n use, the placement cover 1 is attached to an electric connector 2 by
pushing it against the top of the electric connector 2 until the main engagement
legs 6 ride down the connector sidewall outer surface 4a until their gripping
portions 112 effectively catch in the sidewall recesses 4c. Simultaneously, the
auxiliary engagement legs 9 ride down along the connector sidewall surface 4b
until the sidewall 4 is effectively sandwiched therebetween. The cover plate 8
thereupon lies upon the connector insertion slot 10 of the connector 2. Inasmuch
as the auxiliary support legs 9 extend along the interior 4b of the connector
sidewalls 4, each such sidewall 4 is thereby supported by the engagement legs 9
against the forces applied by the main engagement legs 6 of the collector
placement cover 1.
When carrying the electric connector 2 to a printed circuit board, the
placement member 1 is picked up applying a negative pressure to the flat top
surface 7 of the placement cover 1, and then the placement cover-connector
assembly is transferred to the printed circuit board 100. Then, the
connector-board assembly are passed through a reflow vessel, in which solder
