Definitions

  • the present invention relates to an electrical connector suitable for making electrical connections to printed circuit boards to provide good electrical continuity, and in conjunction with the connector of the type, to an electrical connector suitable for electrically connecting two printed circuit boards to each other with good electrical continuity effect.
  • the document US-A-4 084 874 discloses a connector with check-mark shaped contactors, whereby the curved contact portion of the first one is positioned rearwardly relative to the curved contact portion of the other.
  • the connector has a relatively high retention force upon an inserted board, but provides very little resistance during its initial insertion.
  • an electrical connector has a multiplicity of independent connector strips disposed in parallel relation in its body in which two printed circuit boards are inserted, in order to insure electrical continuity of the printed circuit boards.
  • a multiplicity of connector strips are individually incorporated into the body of the connector; this means poor efficiency of assembly operation and makes it difficult to manufacture such connector on a mass production basis.
  • individual connector strips incorporated into the body may easily short as a result of poor workmanship, if any, in the process of assembly work.
  • the present invention is intended to overcome these difficulties, and accordingly it is a primary object of the invention to provide a connector which is simple in construction and is greatly improved in respect of service durability.
  • the connector in accordance with the present invention comprises a first series of spring contactors of check-mark shape disposed in a space defined between opposite walls of a body and adjacent one of said walls, a front end portion of each of said first spring contactors being held in abutment with the outer surface of a locking strip portion provided adjacent an open portion of said space, a second series of spring contactors held in contact with the outer surface of the other wall and having a curved front end portion of U-shape which is fitted over the front end portion of said other wall, said U-shaped portion having at its front end a curved portion which is generally inverted check-mark shaped, said inverted check-mark shaped portion projecting into said space, the check-mark shaped curved portion of said first spring contactor being positioned rearwardly relative to the generally inverted-check mark shaped curved portion of said second spring contactor, whereby a printed circuit board can be obliquely inserted into and removed from a space between said curved portions, and whereby when the printed circuit board
  • the printed circuit board is inserted in non-contact or slight contact condition between a first contact formed by the curved portion of the first series of spring contactors and a second contact formed by the curved portion of the second series of spring contactors, and therefore neither of the first and second series of spring contactors is deformed upon insertion of the printed circuit board.
  • the first contact is pressed by the circuit pattern of the printed circuit board so that the entire first series of spring contactor is deflected toward one of the wall portions, and the second contact is pressed so that the entire second series of spring contactors is deflected in a direction away from the outer surface of the other wall portion.
  • the first and second contacts go into pressure contact with the printed pattern so that good electrical connection is established.
  • the possibility of the first and second spring contactors rubbing forcibly against the printed pattern of the printed circuit board is eliminated which would otherwise develop when the printed circuit board is inserted into and removed from the connector.
  • the first contact or the curved portion of the first spring contactor
  • the second contact or the curved portion of the second spring contactor
  • first and second spring contactors are subject to deflection in their entirety means that respective strokes of the first and second spring contactors as connector strips are considerably long, and further that spring pressures of the first and second spring contactors can be easily balanced. Therefore, the second spring contactors are not liable to scraping under the spring force of the first spring contactors,it being thus possible to insure much more reliable pressure contact between the spring contactors and the printed circuit board and longtime good electrical continuity.
  • each second spring contact since the front end curved portion of U-shape of each second spring contact is fitted on the other wall portion so that the front end portion of the U-shaped portion which is generally inverted check-mark shaped is caused to project along the inner surface of the other wall portion, if said U-shaped front end portion is going to be scraped, it is steadily supported on the inner surface of said other wall portion so that it can be effectively prevented from getting scraped. Because of these facts, therefore, the spring contactors may be made of a relatively low-cost material.
  • first spring contactors can be mounted in position from the rear side of the body, and the second spring contactors from the front side of the body; therefore, each series of these contactors can be so preloaded as to move toward the other series of contactors. Through such arrangement it is possible to insure more reliable electrical continuity with the circuit pattern of the printed circuit board.
  • the arrangement of the invention eliminates the necessity of providing an opening/closing member and/or a manipulating member therefore in order to open and close the pairs of spring contactors. This brings about variout practical advantages, such as greater simplicity in construction, freedom from operational complexity, and considerable cost reduction.
  • the connector in accordance with the invention further comprises a body including an upper body portion for removably receiving one side portion of a printed circuit board and a lower body portion for removably receiving one side portion of another printed circuit board, the rear ends of said upper and lower body portions being integrally connected to each other by side walls, a release opening extending between said side walls in the longitudinal direction of the body, a spring contactor insertion opening formed at the rear side of each of said upper and lower body portions, said body being generally of U-shape, a first connector strip group comprising a multiplicity of generally U-shaped first connector strips arranged in parallel, each of said first connector strips including a first upper spring contactor which resiliently contacts the upper surface of said one printed circuit board inserted into said upper body portion and a lower spring contactor which resiliently contacts the lower surface of said other printed circuit board inserted into said lower body portion, the rear ends of said first upper and lower contactors being integrally connected by a coupling strip portion, the
