ABSTRACT:
Electrical pin (10) for solderless insertion into metallized apertures of circuit boards, comprising an elastically deformable press-fit portion (14) with four contact areas (26), which are located on a first larger diameter (28) as compared with the diameter of the apertures of the circuit boards. A positioning portion (18) is provided ahead of the press-fit portion (14) and a transition portion (16) lies therebetween. The positioning portion (18) also has four contact areas (36), which are located on a second diameter (30) slightly smaller than the diameter of the apertures. Contrary to the press-fit portion (14) the positioning portion (18) is not deformed during the insertion of the electrical pin (10). Due to the positioning portion (18) the electrical pins can be connected to the circuit board in two operation steps, the first one being the positioning step and the second one being the press-in step. Due to the positioning portion (18) the electrical pins are pre-positioned in the apertures one by one and are held non-tiltable in the apertures and, after having transported the circuit board to a second station, all pins are commonly pressed into the apertures by a simple press-in die.
