Definitions

  • the present invention relates to a connector and, more particularly, to the structure of a press-fit connector having an insulative body which may be pressed to in turn press-fit contacts in individual through holes of a printed circuit board.
  • a prior art press-fit connector of the kind described is constituted by a contact which is to be press-fitted in a through hole of a printed circuit board, and a housing made of an insulating material and provided with a bore in which the contact may be removably received.
  • the contact is formed with a single lance, or portion engageable with the housing, on its periphery.
  • the lance is engaged with a shoulder which is provided in the bore of the housing and, then, the housing is bodily pressed.
  • Another prior art press-fit connector includes a contact which is provided with a plurality of lances on its periphery.
  • the lances are engaged with the bottom of a housing and, then, pressed by the housing to become press-fitted in a through hole of a printed circuit board.
  • a drawback with the single lance type press-fit connector is that the contact is apt to rotate during press-fitting and, therefore, to fall after press-fitting.
  • a problem with the multiple lance type press-fit connector is that the dimension of each lance available are limited because, when the contact of one connector is press-fitted, its lances are liable to make contact with those of adjacent connectors resulting in the interconnection of unexpected connectors. This in turn reduces the area over which the bottom of the housing and the lances engage each other, thereby preventing a sufficient press-fitting function from being accomplished.
  • a specific object of the present invention is to provide a reliable press-fit connector.
  • Another specific object of the present invention is to provide a press-fit connector which can be surely mounted on a printed circuit board and others.
  • a structure of a press-fit connector of the present invention comprises at least one contact having projections which extend out away from each other from opposite sides of the contact with respect to an axis of the contact and are distant from each other in an axial direction of the contact, and a presser member having portions with which the projections of the contact are individually engageable, for pressing the contact into press-fit in a through hole.
  • a prior art press-fit connector is made up of a contact 10 having a lance 12 on one of its opposite sides, and an insulative housing 14 having a bore 16 for receiving the contact 10.
  • the housing 14 is notched to have a shoulder 18 with which the lance 12 is engageable.
  • the housing 14 is pressed downward so that the shoulder 18 being engaged with the lance 12 urges the latter downward.
  • FIGs. 3 and 4 there is shown another prior art press-fit connector which is constituted by a contact 20 having lances 22 and 24 on its opposite sides, and an insulative housing 26 having a straight bore 28.
  • the lances 22 and 24 are shaped by cutting the contact 20.
  • the contact 20 is press-fitted in a through hole of a printed circuit board by abutting flat ends 22a and 24a of the lances 22 and 24, respectively, against a flat end 26a of the housing 26 and, then, pressing the housing 26 downward.
  • the lance 12 is provided on only one side of the contact 10 and, therefore, the position where the lance 12 and the shoulder 18 of the housing 14 abut against each other is deviated from the axis of the contact 10.
  • a force tending to rotate the contact 10 is developed while the contact 10 is press-fitted, resulting that the contact 10 is apt to fall after press-fitting and/or a spring, not shown, associated with the contact 10 is apt to be dislocated.
  • the connector shown in Figs. 3 and 4 is free from such a force because the contact 20 is provided with the lances 22 and 24 on opposite sides thereof.
  • each lance 22 or 24 cannot be designed longer than a certain limit.
  • mechanical strength is proportional to the area of a portion for abutment. It follows that the lances 22 and 24 whose dimensions are limited as stated above are unable to achieve abutting strength great enough to guarantee firm press-fit of the contact 20 in a through hole of a printed circuit board while, at the same time, scattering in pressing force is unavoidable.
  • a press-fit connector embodying the present invention is shown and generally designated by the reference numeral 30.
  • the connector 30 is shown in a fragmentary sectional perspective view in Fig. 6.
  • the connector 30 comprises a housing 32 made of an insulating material, and a plurality of contacts 34.
  • the housing 32 is provided with a flange 36.
  • a plurality of through bores 38 extend vertically throughout the housing 32 in order to individually receive the contacts 34.
  • the upper end of each bore 38 merges into a window 40 which is formed through the housing 32 for receiving another contact.
  • each through bore 38 is contiguous with a recess 42 at its lower end portion.
  • the recess 42 is formed by notching the inner side wall of the housing 32 downward and terminates at a flat upper end, or shoulder, 44.
  • the bottom 46 of the housing 32 is formed flat.
  • Each contact 34 includes a spring portion 48 having two lugs 48a, projections 50 and 52, and a press-fit portion 54. Formed by bending the upper end portion of the contact 34, the spring portion 48 is adapted for pressing engagement with another contact which may be inserted through the window 40 of the housing 32.
  • the projections 50 and 52 extend out perpendicular to the axis of the contact 34 and away from each other. As shown in Fig.
  • the projections 50 and 52 are apart from each other in the axial direction of the contact 34 by a distance which is selected to cause the projection 52 to abut against the bottom 46 of the housing 32 when the projection 50 abuts against the shoulder 44.
  • the upper surfaces 50a and 52a of the projections 50 and 52, respectively, are formed flat to make positive contact with the housing shoulder 44 and the housing bottom 46, respectively.
  • the press-fit portion 54 Located in a lower portion of the contact 34 as viewed in the figures, the press-fit portion 54 has resiliency.
  • the connector 30 is positioned above a printed circuit board 56, Fig. 9, such that the axis of each contact 34 is aligned with that of its associated through hole 58.
  • the housing 32 is pressed downward so that the press-fit portion 54 of the contact 34 is press-fitted in the associated through hole 58 of the printed circuit board 56 with the projection 50 abutting against the housing shoulder 44 and the projection 52 abutting against the housing bottom 46. Since the pressure force applied to the housing 32 is evenly distributed to the projections 50 and 52 which are located at opposite sides of the axis of the contact 34, the contact 34 is allowed to enter the through hole 58 in a vertical position without being rotated.
  • the entire pressure force acting on the housing 32 is imparted to the contact 34 to surely press-fit it in the through hole 58 inasmuch as the projections 50 and 52 of the contact 34 contact, respectively, the housing shoulder 44 and housing bottom 46 each over a substantial area.
  • a force which is applied to the housing 32 for press-fitting the contact 34 in the through hole 58 of the printed circuit board 56 is allowed to act on the same axis to prevent the contact 34 from being rotated. This is because the projections 50 and 52 extending away from each other from the contact 34 are engageable with the housing 32.
  • the projections 50 and 52 are distant from each other in the axial direction of the contact 34. Hence, the distance between the outermost ends of the projections 50 and 52 as measured in a direction perpendicular to the axis of the contact 34 can be designed substantially as great as the intercontact pitch of the connector.
  • the contact 34 therefore, is allowed to make contact with the housing 32 over an area which is wide enough to insure mechanical strength against the press-fitting force.
