Definitions

  • the present invention relates generally to an electrical connector, more specifically to a connector having female electrical contacts for receiving complementary mating male contacts and particularly suited for compact and high-density requirements.
  • the female electrical contacts ' in a plurality of parallel contact-receiving cavities in an insulation housing are secured therein by sharp projections formed at both sides of such contacts to engage inner walls of the cavities and by forming box-shaped support sections near openings of the contact-receiving cavities for insertion of complementary mating male electrical contacts.
  • the housing tends to be curved or deformed due to strong forces by the projections at both sides of the female electrical contacts to the walls defining the contact-receiving cavities and also due to a large number of electrical contacts inserted in the contact-receiving cavities arranged in one direction.
  • the securing of the contacts in this manner in the contact-receiving cavities adversely affect them thereby resulting in an inaccurate pitch of the contacts.
  • female electrical contacts having box-shaped support sections are relatively bulky, thus, they are not desirable to meet miniature and high-density requirements for a connector and difficult to reduce production costs due to relatively thicker metal required for the contacts.
  • the present invention intends to solve the above problems.
  • the electrical connector comprises an insulation housing having a plurality of contact-receiving cavities with first and second openings between first and second ends ' thereof, and female electrical contacts to be inserted in the cavities from the first openings thereof.
  • Each contact is made from an electrically-conductive metal plate by stamping and forming and comprises a base section having first and second surfaces and first and second ends, and an engaging section to secure it to walls of the cavities.
  • the base section extends along the axis of each female electrical contact and the first surface engages with the first wall of each cavity.
  • a pair of resilient arms defining the contact-receiving section extend from support sections bent relative to the second surface from both sides of the base section at the first end thereof toward the second end of the base section. Raised edges formed at the support sections engage the second wall opposite to the first wall of the cavity.
  • Engaging members constituting the engaging section extend from both sides of the base section adjacent to the first end of the base section and are pressed into channels of a predetermined length formed in opposing third and fourth walls of the cavity in the housing from the first end to the second end.
  • Wing members formed at both sides of the base section at the second end thereof engage the third and fourth walls at both sides of the first wall of the cavity adjacent the second opening of the cavity or are pressed into gaps formed between the first wall adjacent to the second opening of the cavity and the third and fourth walls crossing the first and second walls.
  • the engaging strip ends of the engaging section are twisted to an angle with respect to the extension of the engaging strip to provide resiliency to planar pressure and the height of the strip ends is chosen to be greater than the height of the channels.
  • engaging members of the engaging section are separated in a stepped manner to provide resiliency to planar pressure with the height of the separated engaging members being greater than the height of the channels.
  • wing members of the base section have bent ends relative to its first plane to provide planar pressure at the bent ends.
  • the engaging members constituting the engaging section of the female electrical contact are pressed into the channels in the housing, the base section of the contact engages the wall of the contact-receiving cavity, the upper edges at the support sections of the contact engage the wall of the cavity opposite to the first-mentioned wall, and the wing members formed at both sides of the body section distant from the support sections engage with both walls crossing the aforementioned two walls, thereby totally stably securing the contact in the housing.

  • insulation housing 30 for assembling contacts 10 therein.
  • contacts 10 are assembled in insulation housing 30.
  • Housing 30 is made of a suitable plastic material or the like by molding and has first end 30a and
  • Housing 30 contains many contact-receiving cavities 33 separated into two rows by horizontal wall 31 and several columns by vertical walls 32, so that each cavity 33 is defined by four walls, namely first and second walls 31a, 31b and third and fourth walls 32a, 32b crossing first and second walls 35 31a, 31b.
  • Each cavity 33 has first and second openings 33a, 33b.

  • FIGS. 7 and 8 Shown in FIGS. 7 and 8 is another embodiment of contact 10.
  • Contact 10' in this alternative embodiment features dividing ends 23' of engaging members 22' of engaging section 14' into two parts by slits 24 and biasing one part from the other in a stepped manner to provide resiliency to planar pressure.
  • Height H of engaging ends 23' is chosen to be greater than width W of channels 34 and the thickness of base section 11'.
  • Shape and construction of contact 10' are identical to those of contact 10 in all other sections.
  • engaging ends 23, 23* are preferably twisted or formed in a stepped manner, but they may be simply made to be slightly thicker than the width of the channels in which they are to be secured.
  • wing members 15 are preferably made to have bent ends 15a to be forced in spaces 38 but may be designed to be pressed therein without forming bent ends 15a. In some instances, ends of the wing members may be frictionally pressed against both walls 32a, 32b.
  • the connector as described herein may be used, for example by inserting post portions 13 of female electrical contacts 10 into holes of a printed circuit board and electrically connected with male electrical contacts of a complementary mating connector by inserting such male electrical contacts in contact-receiving sections 12 of contacts 10.
  • the base section of the contact engages with the wall of the contact-receiving cavity in the housing, the projections at the support sections of the contact engage the wall opposite to the first mentioned wall of the cavity, and the wing members at both sides of the base section distant from the support sections also engage two walls crossing the above two walls and/or are pressed into the spaces formed near the second opening of the cavity.
  • the connector according to the present invention helps to avoid curving or deformation of the housing and irregular alignment of adjacent contacts because the engaging members of the engaging section apply pressure only to the channel width direction, i.e., the housing height direction. Since more contact cavities are generally formed in the length direction than the height direction of the housing, the present invention is particularly effective for those connectors having a large number of contacts.
  • the engaging ends of the engaging section are twisted or separated and formed in a stepped manner to provide resiliency and to have a greater height than the width of the channels, the frictional strength between the channels increases thereby strengthening the engagement between the engaging members and the channels and, in turn, reliably securing the female electrical contacts in the housing.
  • bent ends at the wing members of the base section provide resiliency to planar pressure, thereby strongly stabilizing the contact in the housing, if they are pressed in the spaces.
