Abstract: A connector of the unitary type with dual-beam contacts is adapted to be inserted in the body of a receiving female connection part and includes a holding beam forming a guiding means for the connector in the body of said connection part and a pair of resilient flexible beams. The two oppositely located beams are disposed substantially perpendicularly to the holding beam, each flexible beam having a contact area, the three connection beams defining together a free entry opening. The connector also includes a bight on which are supported the three connector beams, the bight carrying the output lead of the connector.

Abstract: A connector comprises a plug of electrically insulating material and a housing box for accommodating electric contacts therein. The plug is selectively insertable in the box and comprises at least one first element insertable in a bore of the box formed for accommodating the contacts, and a second element for insertion in a corresponding opening of a printed circuit board. The plug selectively includes a bore for receipt of a complementary electric contact or a lug closing the box bore for preventing receipt of a complementary electric contact.
