Base alloy plated printed circuit edge connector - has simple triangular shaped sprung contact lead tin plated with tipping and sliding contacts and low wear

摘要

The semisliding action with progressive pressure so that lead-tin plates contacts are capable of more than 500 operations without deterioration; the card is held automatically in place by the contacts by symmetrical 4 point pressure on both sides the connectors are designed to the dimensions of the dual sided HE9 standard format. The connector consists of a flat triangle whose corners (6,7,8) are made by bending a metal strip. The base (9) of the triangle forms the contact with the card and the apex (8) is rounded following a semicircular arc. A part (13) of the base between the corners is indented so that only a part of the base may contact the card. The end of one side (11) rests inside the semicircular apex which is connected by a tongue (14) and a weld to the output pin (16). The connector is plated with a lead tin alloy. The contacts (5) are housed in seatings (4) in an insulating block (1) with a window to receive the circuit card. The connector tips in its plane with the movement limited by an insulating lug (21). The corners of the contacts form V-shaped springs and the lug determines the initial contact angle.
