  • Electrical connector for circuit boards
    Patent number: 5160275
    Abstract: An electrical connector is provided which, when attached to a printed circuit board, will not cause removal of a cream solder that has been applied to the circuit board, and which will not flaw the surface of circuit portions. The connector has a resilient arm which undergoes elastic deformation to flex contacts perpendicularly away from the surface of the circuit portions when the circuit board is inserted into the connector. The resilient arm is restored to its original shape when the connector has been correctly fitted on the circuit board, thereby allowing the contacts to contact predetermined circuits. In another embodiment, the resilient arm is replaced by a frame member which is urged into the connector body by the circuit board. This causes the contacts to part perpendicularly from the surface of the circuit portions.
