PCT No. PCT/US91/07602 Sec. 371 Date Nov. 12, 1991 Sec. 102(e) Date Nov. 12, 1991 PCT Filed Oct. 15, 1991 PCT Pub. No. WO93/08619 PCT Pub. Date Apr. 29, 1993.A connector is described, of the type that has pegs for insertion in holes of a circuit board to securely hold the connector to the board, wherein the pegs can be easily installed, and they assure secure holding despite variations in circuit board thickness and moderate tolerances in the diameters of the circuit board holes. Each of the pegs (41, FIG. 4 ) has a peg body (60) with an axis (62), and a plurality of ribs (71-73) projecting radially outwardly from the periphery of the body. The pegs are constructed of material of lower hardness than the material of the circuit board, so the interference fit between the pegs and circuit board results in flattening of the tips of the ribs and/or shaving of the tips of the ribs. Each peg has a slot (66) extending from the periphery of the peg body to near the axis of the peg body, and a pair of the ribs lie on opposite sides of the slot, so radially-inward pressure on the ribs causes the slot to close slightly and allow the ribs to move radially inwardly. The slots of adjacent pegs are oriented so they are turned 90 DEG from each other to reduce the insertion force and the possibility of peg breakage.
