Definitions

  • the present invention relates to a female connector including a plurality of plug-in contacts insulated by the connector housing, said contacts being associated with contact pressure determining springs, and locking means to lock said contacts in said housing.
  • Such a female connector is known from the U.S. Patent 3,268,850 (J. Bernutz 73).
  • An object of the present invention is to provide a female connector of the above type, which offers a double number of connection possibilities with respect to the above known connector for a comparable size.
  • the invention is based on the insight that the known female connector incorporates double spring contacts that ensure a good contact reliability in the most adverse cases, i.e. when very frequent removals of the male connector thereto associated are foreseen. In applications where such removals of the male part are not so frequent, it is no longer essential to have double contacts to ensure a satisfactory contact reliability. For the latter applications a female connector with simple contacts and of suitable design may be reliable as well.
  • the present female connector is characterized by the fact, that each of said pressure determining springs is mechanically associated with a pair of contacts while keeping them electrically separate.
  • a female connector including a plurality of plug-in contacts insulated by the connector housing, and locking means to lock said contacts in said housing, is characterized by the fact, that said housing is constituted by a contact support and a cap respectively carrying first and second engaging elements, said rst engaging elements being arranged to engage and lock with the corresponding second elements when said cap is pressed on said contact support, and that said locking means are constituted by the upper part of said cap which prevents the shifting of said ⁇ contacts out from :said housing while enabling the insertion of a male connector.
  • FIGS. 1 and 2 respectively represent an upper and a 3,509,519 Patented Apr. 28, 1970 ICC side view of a female connector in accordance with the invention
  • FIG. 3 is a cross-sectional view taken along the axis IIIIII of FIGS. 2 and 4;
  • FIG. 4 represents an upper plan view of a part of the insulated housing of the female connector of FIG. 1;
  • FIGS. 5 and 6 respectively show a front and a side view of a plug-in contact of the connector of FIG. 1.
  • the female connector shown therein comprises an insulating housing 1, constituted by a contact support 3 and a cap 2, and a plurality of plug-in spring contacts 6.
  • FIG. 4 shows an upper plan View of a part of support 3.
  • the cap 2 is provided with four holes 4 and one elastic stud 10, on each of its longitudinal sides and at the bottom of each of its two end parts respectively. These holes 4 and studs 10 engage withcorresponding elastic studs 7 and recesses 5 of support 3, when cap 2 is pressed thereon, thus performing the locking of the two constituent pieces 2 and 3 of housing 1 with respect to each other.
  • the upper part of cap 2 is provided with a slot 11 which enables the insertion of an appropriate male connector (not shown) in housing 1.
  • This male connector may for instance be constituted by the edge part of a printed circuit board carrying on each side thereof a set of parallel conductors arranged to tit with the respective contacts 6 of the female connector.
  • the contacts 6 are at and U- shaped, each one having a long leg protruding from the bottom of support 3 through a corresponding hole 12, and a short leg of which the free end is housed in a corresponding recess 13 of support 3.
  • the short leg of each contact 6 constitutes its contacting member, whereas the part of the long leg thereof protruding from housing 1 constitutes its connection tail, which may receive a suitable conductor (not shown).
  • the contacts 6 are arranged in the support 3 in two parallel rows, each contact 6 of one row having a homologue contact in the other row.
  • Each pair of homologue contacts 6 is associated with a corresponding contact pressure determining spring 8, which is flat and substantially U-shaped.
  • Each pressure spring 8 is in the same plane with its associated pair of contacts 6, this plane being perpendicular to the two parallel rows of contacts.
  • the two legs of a spring 8 project in the curved concave parts of its associated pair of contacts 6 and they are kept electrically insulated therefrom by means of two insulating ribbons 9, respectively extending through the whole length of the two contact rows.
  • Each of the pressure springs 8 carries a projection 15, which ts in a corresponding hole 14 at the bottom side of support 3.
  • the upper part of cap 2 partially covers the convex parts of contacts 6 of both rows, so that it prevents their shifting in the plug-out direction.
  • the projecting parts of the long legs of contacts 6 are narrower than the remaining contact parts, so that the corners 17 thereof (FIG. 5), which are supported by the bottom part of support 3, prevent the exertion of a high pressure on the insulating ribbons 9 during the male connector insertions. In this way, the ribbons 9 are protected against wearing and tearing of their parts pressed by the pressure springs 8 on the curved parts of contacts 6.
  • Each of the contacts 6 is provided with a longitudinal slot 16 (FIGS.
  • An electrical connector for -mating with a printed circuit board comprising:
  • a connector housing formed of insulating material
  • each of said contacts being substantially U-shaped and having a short leg constituting contacting member and a long leg having a free-ended part which protrudes from said housing to form a connection terminal, the short legs of each of said pairs of contacts being adjacent to and facing each other;
  • spring means coupled to said pair of contacts and mounted in said housing, said spring means being substantially U-shaped with one of the legs of each of the spring means projecting between the legs of each of said pairs of contacts, keeping said contacts electrically separated.
  • each of said contacts are insulated from its respective spring means by means of an insulaitng ribbon.
