  • Patent number: 9598784
    Abstract: A contact element (25) (electroformed product) is produced by electroforming. The contact element (25) has a surface on which an insulating film (28) having been formed by use of a dry film resist or the like is provided. In a process of producing the contact element (25), the insulating film (28) is provided after a step of producing the contact element 25. This makes it possible to provide electroformed components configured so that respective electroformed products (contact terminals) are arranged at narrow pitches while maintaining electrical insulation of the electroformed products from each other.

  • Patent number: 9595773
    Abstract: A probe pin has a coil spring having a first end and a second end, a first plunger having a major portion, and a first elastic extension and a second elastic extension that from the major portion in the same direction, and a second plunger forcedly inserted between the first and the second elastic extensions. The first and the second plungers have electric conductivity. The first and the second plungers are inserted from the first and second ends of the coil spring, respectively, so that the first and the second elastic extensions of the first plunger hold the second plunger with the first elastic extension making a forced contact with a surface of the second plunger to form thereat an electric connection between the first and the second plungers.

  • Patent number: 9590346
    Abstract: A connecting mechanism having a male contact and a female contact, each of the male and female contacts having a first surface including at least in part a flat surface portion defined therein, a second surface opposing the first surface, and a contact surface extending between the first surface and the second surface. The contact surface is designed so that, when the first contact and the second contact are electrically connected with each other, the contact surfaces of the first contact and the second contact make a surface contact therebetween that inclines with respect to the flat surface portions of the first and second contacts in a cross section that crosses the first surface, the second surface, and the contact surface.
