housing 10 and header 50 joined in a fully mated position while the cpa 12 is located in an initial pre staged position fig6 illustrates a sectional view taken along line 6 6 in fig5 showing a top plan view of the plug housing 10 and header 50 with the top wall 100 of the shroud 94 removed as shown in fig5 6 the cpa 12 is located with the main section 132 disposed between the flared end walls 56 the cpa main sides 146 are spaced a distance d 1 from the end walls 56 the cpa outer sides 148 are spaced a distance d 2 from the interior side surfaces 150 of the latch beams 28 the distances d 1 and d 2 are sufficient to permit the latch beams 28 to be deflected in the direction of arrows a and b when the header 50 and plug housing 10 are joined in a mated relation once the header 50 and plug housing 10 are fully mated the latch projections 36 snap behind the embossments 110 thereby permitting the latch beams 28 to be deflected outward to their rest positions as illustrated in fig6 once the plug housing 10 and header 50 are fully mated the cpa 12 may be moved to its engaged position as illustrated in fig7 and 8 0041 fig7 illustrates an isometric view of a plug housing 10 fully mated with a header 50 and in which the cpa 12 is moved to its locked position fig8 illustrates a sectional view taken along line 8 8 in.
