  • Patent number: 5049511
    Abstract: A resilient connector capable of being inserted into a printed circuit board comprises a clamp head portion and a leg portion. Moreover, the clamp portion has a long arm, a short arm and a base connected between the long arm and the short arm. The leg portion is formed by longitudinally severing a part of the intermediate portion of the clamp head portion, which extends from an intermediate position of the long arm to an intermediate position of the base. Thus, the printed circuit board can be inserted into, and brought into contact with, the contact surface of the clamp head portion. Subsequently, the printed circuit board may be pivoted to a second angular position from a first angular position. Preferably, the second angle is selectively designed at a 25 degrees orientation to assure the conservation of space.
