Definitions

  • the present device relates to components used to affix or mount an electrical connector to a printed circuit board, in particular, to components of the electrical connector used to affix the housing of the electrical connector to the board.
  • Another know affixing member of an electric connector includes a pair of forked metal legs which are attached to both ends of the housing of the electrical connector where each forked metal leg has two tines.
  • the two tines of the metal legs are configured to have a greater width or diameter than the diameters of corresponding insertion holes of a board.
  • the metal legs are forcibly inserted into the corresponding insertion holes of the board thus reducing the diameter of the metal legs to diameters of the insertion holes so that the metal legs and correspondingly, the housing, is affixed to the board.
  • a latching claw may be provided at the forward end of the tines of each forked leg. In operation, the latching claw is used to latch the rear surface of the board so that the metal legs and correspondingly, the housing, are more positively affixed to the board.
  • know affixing members including plastic legs tend to be deformed when inserted into the hole in the board due to the excessive stress produced by reducing the diameter of the legs to the diameter of the board.
  • Know affixing member including metal legs tend to damage the area near the insertion hole of the printed circuit board or the inner wall of the insertion hole due to rigidity of the metal legs and latching claws (if used) and the pliable nature of the printed circuit board.
  • the know affixing members including plastics legs and metal legs require mounting space greater than the thickness of the printed circuit board.
  • the legs when inserted, project below the printed circuit board so that it becomes necessary to secure space below the printed circuit board for the legs.
  • the additional space required for these affixing members does not meet the demands for reduced space consumption of printed circuit boards, in particular, in such applications as notebook computers, etc.
  • an object of the present invention to provide an electrical connector or an affixing member of an electrical connector which overcomes the above mentioned problems of known affixing members.
  • Another object of the present invention is to provide an electrical connector or an affixing member of an electrical connector which does not require space below the board when inserted, thus alleviating the need of securing space below the board.
  • the present invention provides an electrical connector to be affixed to a printed circuit board having an insertion hole; the connector including
  • Figure 1 is a partly broken away side view of an electrical connector or an affixing member of an electrical connector according to one embodiment of the present invention with a push pin not yet inserted into a cylindrical member.
  • Figure 2 is a partly broken away perspective view of the cylindrical member shown in Figure 1 viewed from the lower side of the connector housing.
  • Figure 3 is a side view showing the affixing member with the push pin temporarily inserted into the cylindrical member in a way corresponding to Figure 1.
  • Figure 5 is a side view of an affixing member similar to member shown in Figure 4 except that the affixing member is designed to project below the lower surface of a printed circuit board.
  • an electrical connector or an affixing member of an electrical connector of the present invention includes a push pin 2 and a cylindrical member 4 designed to receive the push pin when inserted therein.
  • the push pin 2 has a head 6 and a pin section 8 extending from the head.
  • a projection 12 on the pin section 8 is provided at an area between a base end (by the head) and a forward end 10 of the pin section 8, that is, at a middle area of the pin section 8.
  • the projection 12 is formed concentric with the pin section 8.
  • the forward end 10 of the pin section 8 has an outer diameter of ⁇ 1.
  • the cylindrical member 4 is integrally molded with the connector housing 14.
  • the cylindrical member 4 is situated in a lower recess 16 on the lower surface side of the injection-molded type plastic housing 14 of the electrical connector.
  • an upper recess 18 is provided on the upper surface side of the connector housing 14 to receive the head 6 of the push pin 2.
  • the lower recess 16 and upper recess 18 communicate with each other via a passage 20 through which the pin section 8 of the push pin 2 may be inserted.
  • An inner diameter ⁇ 2 of the passage 20 is made somewhat larger than the outer diameter ⁇ 1 of the forward end 10 of the pin section 8.
  • the hollow section 22 also has a small-diameter section 22b situated below the large-diameter section 22a of the hollow section 22, the small-diameter section 22b having an inner diameter ⁇ 3 which is much smaller than the inner diameter ⁇ 2 of the large-diameter section 22a and outer diameter ⁇ 1 of the forward end 10 of the pin section 8.
  • a plurality of contact terminals (not shown) for board-to-board interconnection are arranged in the housing 14.
  • the outer diameter ⁇ 1 of the forward end 10 of the push pin 2 is greater than the inner diameter ⁇ 3 of the small-diameter section 22b of the hollow section 22.
  • a inward reaction force is generated from the inner wall of the insertion hole 32 of the circuit board 30 against the outward force created by the four arcuate columns 26 being pressed outwardly spread by the pin section 8 of the push pin 2.
  • an elastic force is generated by the plastic arcuate columns 26 which are trying to retain their initial volume.
  • the arcuate columns 26, and thereby, the cylinder member 4 become affixed to the insertion hole 32 of the circuit board 30.
  • the electrical connector housing 14 also becomes affixed to the circuit board 30 since the cylindrical member 30 is integrally molded to the housing 14.
  • the cylindrical member 4 may be configured so that its lower end may project below the lower surface of the circuit board 30 as shown in Figure 5. In this configuration of the cylindrical member 4, additional affixing force is obtained.
  • the connecting member 28 is comprised of the circular disc made of plastics which is broken when the pin 2 is fully inserted into the cylindrical member 4, the material, shape and characteristics of the connecting member 28 are not so restricted.
  • the material selected for the connecting member 28 (and connector housing 14) may be a resin (such as a resin containing a small amount of or no glass).
  • the connecting member may be formed having a greater elongation or to have other configurations, such as a criss-cross configuration.
  • the connecting member 28 may not be broken when the forward end 10 of the push pin 2 is inserted into the small-diameter section 22b of the hollow section 22 because the connecting member 28 may be elongated to a thin thickness without being breaking.
