Definitions

  • the present invention relates to an improved receptacle terminal and in particular to one which can be readily and accurately formed with a true square cross section.
  • a difficulty in producing terminals of the above described type is that the semi-elliptic springs are uniform along their length and come in to interfering contact when the receptacle portion is formed. It is the interference of these springs that has prevented such terminals from being formed with an accurate square cross section. This causes subsequent mounting and alignment problems and becomes a particular problem when it is desired to use the box-like receptacles in a high density closely spaced configuration where accuracy in forming becomes an important criteria due to space limitations.
  • the present invention relates to an improved receptacle terminal which has two spaced apart axially aligned square frame sections interconnected by four spring arm members each integral at its ends with a corresponding side of a respective frame section.
  • Each spring arm is inwardly concave with respect to the axis of the socket and is formed with a uniform taper extending inwardly from each end to their point of narrowest approach at the center of each spring arm. The taper gives each spring arm sufficient stiffness to be the functional equivalent of the prior art straight beams while allowing the contact points to be formed with a smaller gap than straight beam contacts.
  • the socket terminal also includes retaining ears, locking lances, and an interconnect portion which may be, for example, a mounting post, solder pin, or crimp barrel.
  • the subject socket terminal 10 has two spaced apart substantially square end or frame sections 12, 14 which are interconnected by four spring arms 16, 18, 20, 22, each spring arm being integral with corresponding sides of the end sections.
  • Each spring arm is semi-elliptic and is inwardly tapered from the ends towards the center.
  • the semi-elliptic shape of the spring arms brings their center sections into close proximity as best seen in Figure 3. Their inward taper from their ends allows these central portions to be freely formed, without interfering with one another, while providing contact forces equal to or better than those provided by previous socket terminals.
  • Socket terminals of this type are advantageously manufactured by die stamping and forming so that an open seam 24, 26 remains in one corner of each end section.
  • The'spring arms 16, 18, 20, 22 are concave inwardly towards the axis of the socket but are capable of substantial deflection upon insertion of a terminal pin (not shown) axially of the socket so that a wide range of pin sizes can be accommodated by a single socket size.
  • Laterally extending ears or flanges 28 are provided on the free edge of frame section 12 for mounting purposes.
  • One side 30 of the frame section 14 has an rearwardly extending web 32 from which sidewalls 34, 36 extend. These walls form rearwardly directed extensions or continuations of the adjacent sides of the frame section 14.
  • a retaining lance 38 is struck from the web 30 and extends divergently from the socket axis and has a free end directed towards the frame section 14.
  • the web 32 is here shown as a slightly bowed or U-shaped section which is adapted to be inserted into a hole in a circuit board (not shown) or the like and can be soldered to conductors (also not shown) on the circuit board.
  • This construction permits the achievement of several different types of good patterns of posts in a receptacle block as will be explained below.
  • a plurality of such webs 32 can be interconnected by clip type wiring devices (not shown) or wire wrapping techniques (also not shown) although a different form of post sections may be required for such alternate interconnection methods.
  • this portion of the terminal formed with either an insulation displacing conductor gripping profile, with a crimp barrel, or with a compliant mounting portion, such as those shown in U.S. Patent Nos. 3,805,214; 3,990,143; and 4,186,982, respectively, the disciosures of which are incorporated herein by reference.
  • the present invention may be advantageously be used with a housing of the type shown in U.S. Patent No. 3,404,367, the disclosure of which is incorporated herein by reference.
  • the housing is primarily an elongated block of rigid insulative material having a plurality of through passages each receiving a respective terminal of the subject type.
  • the terminals would extend between mating and mounting faces of the housing and the web portions 32 can even be bent at a right angle to the axis of the terminal for right angle mounting of the connector housings.
  • Terminals according to the present invention can be manufactured in extremely small sizes.
  • terminals of this type have been manufactured from beryllium copper stock with the socket portion having an overall length of about 0.265 inches with end sections of about .046 inches square OD closing to about .018 inches ID at the center of the semi-elliptic springs.
  • This particular socket is used in a receptacle block having cavities spaced apart by 0.050 inches thus permitting a contact density of 400 contacts per square inch. .
