  • Patent number: 6098281
    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.

  • Patent number: 5884773
    Abstract: A sheet metal carrier strip for electrical pins used for the production of electrical multipole connectors, comprises a planar substantially rectangular base portion 24. Two rows of upright legs 26, 30 are formed at each longitudinal edge of the base portion 24. The legs 26, 30 are alternately arranged in parallel vertical planes transversely offset one from another by at least the thickness of the legs 26, 30. A recess 14, 16 is provided in each leg, the recess opening at the upper edge of the leg 26, 30. All recesses 14, 16 in pairs are transversely aligned and designed to insert a contact pin 34 respectively. An interspace formed between each pair of adjacent legs 26, 26 of each row of legs is smaller then the width of the legs 28 of the adjacent row of legs as measured in longitudinal direction of the carrier strip 10, so that a leg 26 of one row is overlapped by a pair of legs 28 of the adjacent row respectively as seen in transverse direction.
