Abstract:
A jack, for electrically connecting a plug to a circuit, comprising:a housing; said housing including a body piece and an insertion piece; said insertion piece having a first perimeter and an insertion hole; said body piece bounding a chamber adjacent said insertion hole; said insertion hole and said chamber being effective to receive said plug along a plug insertion direction; at least a first external connection terminal in said housing; said first external connection terminal including at least a first contact piece, a first elastic piece, a first leg piece, and a first latching tab; said first elastic piece operable parallel to said plug insertion direction; said first leg piece extending perpendicular to said plug insertion direction; said first latching tab fixing said first external connection terminal in at least a first long groove in said housing; said first contact piece extending away from said insertion hole and being proximate said first perimeter; and said first elastic piece and said first contact piece including means for providing an elastic engagement for said plug at a first inner portion of said plug and for displacing said first contact piece toward said insertion hole, whereby said jack enables reliable and elastic electrical connection from said plug to said circuit: at least a second external connection terminal in said housing; said second external connection terminal includes at least a second contact piece extending away from said insertion hole proximate to said first perimeter; a second elastic piece and said second contact piece effective to elastically engage a second inner portion of said plug and said second contact piece being displaced toward said insertion hole when said plug is inserted, whereby said jack enables reliable and elastic multi-pole electrical connection from said plug to said circuit.
