Definitions

  • Integrated circuits are being used in increasing-numbers in equipment utilizing electronic circuitry and they generally take the form of a block in which the electronic circuitry is located and contact members extending outwardly from the sides of the block and then at right angles with respect to a bottom surface of the block.
  • the contact members are generally of tab configuration but they can be pins.
  • An object of the invention is to provide an electrical connector wherein the contacts are readily positioned in cavities of the housing.
  • Another object is the provision of an electrical connector having contact-carrying members which are provided with cavities in which contacts are disposed and the contact-carrying members are latchably secured onto sides of a base.
  • a further object is to provide an electrical connector wherein the cavities of the contact-carrying members and the contacts are provided with securing means securing the contacts in the cavities as Well as enhancing the spring characteristics of the contacts.
  • An additional object of the invention is the provision of guide means at the cavity entrances to guide the contact members of an electrical component into the cavities for electrical engagement with the contacts therein.
  • Still a further object is to provide means along the base of the housing to maintain the housing spaced from a printed circuit board to enable the housing to be ventilated.
  • a still additional object is the provision of means provided by the contacts to prevent wicking of solder into the contact-engaging area thereof.
  • FIG. 1 is an exploded perspective view of an integrated circuit connector prior to being assembled
  • FIG. 2 is a perspective view of FIG. 1 in an assembled condition
  • FIG. 3 is a cross-sectional view of the integrated circuit connector in position on a printed circuit board and an integrated circuit connected thereto;
  • FIG. 4 is a view taken along lines 4--4 of FIG. 3;
  • FIG. 5 is a view taken along lines 55 of FIG. 3.
  • an integrated circuit connector ICC Comprises a dielectric housing H and electrical contacts C.
  • Housing H is molded in accordance with conventional molding techniques from a suitable dielectric material and it includes a base 1 and contactcarrying members 2.
  • Base 1 has essentially a channelshaped configuration with sides 3 interconnected at their midpoints with a central section 4 which maintains sides 3 in position.
  • a hole 5 is disposed in the bottom of base 1 and within central section 4 so that a screw can be received therein to mount the connector in position on a mounting member, if desrired.
  • Stifily-fiexible latching members 6 are located at the ends of base 1 and they are provided with latching projections 7.
  • the upper ends of sides 3 include beveled surfaces 8 and the bottom surface of base 1 includes projections 9 which engage the surface of a printed circuit board, which is illustrated in FIG. 3, in order to maintain the bottom surface of the connectors spaced from the printed circuit board in order to permit proper ventilation of the connector.
  • An annular projection 10 surrounds hole 5 and operates in the same manner as projections 9.
  • Contact-carrying members 2 are provided with cavities 11 at spaced intervals therealong. Each of cavities 11 is provided with lead-in beveled surfaces 12, an entrance 13, tapered surfaces 14 and arcuate surfaces 15. Latching areas 16 are provided in each end of contact-carrying members 2 and these latching areas are engaged by latching projections 7 of stifl'ly-flexible latching members 6 when contact-carrying members 2 are snapped into position on base 1 against sides 3. Latching members 6 therefore securely maintain contact-carrying members 2 in position against sides 3.
  • Contacts C are disposed in cavities 11 and' they are formed by folding a strip of metal to provide a post 17, a bulbous section 18 and bifurcated contact elements 19 having outwardly-directed free ends 20.
  • contacts C are disposed in cavities 11 with bulbous sections 18 disposed in arcuate surfaces 15 and contact elements 19 disposed along tapered surfaces 14 with free ends 20 disposed adjacent surfaces 14a and 14b adjacent entrances 13.
  • Arcuate surfaces 15 maintain the inner ends of contact elements 19 under spring tension so that the contact elements at the beginning of free ends 20 are disposed in touching or near-touching engagement in this area.
  • bulbous sections 18 and arcuate surfaces 15 define securing means to secure contacts C in position in cavities 11 as well as providing spring tension for contact elements 19.
  • Free ends 20 define guide means to guide contact members 21 of integrated circuit IC into electrical engagement with contact elements 19, as illustrated in FIG. 4.
  • Tapered surfaces 14 permit contact elements 19 freedom of movement of contact elements 19 within cavities 11 during engagement of contact members 21 therewith and the outer ends of free ends 20 slide along tapered surfaces 14 during the engaging and disengaging of contact members with con tact elements 19.
  • contact-carrying members 2 are then latched into position via latching projections 7 of latching members 6 latchably engaging areas 16 thereby securing contacts in position in cavities 11 to preclude any sidewise movement.
  • Latching projections 7 and latching areas 16 are provided with beveled surfaces 22 which act as camming means to cam latching members 6 in an outward direction so that latching projections 7 can be properly mated with latching areas 16.
  • posts 17 are positioned in openings 23 of printed circuit board 24 and posts 17 are flow soldered to circuit paths 25 in accordance with conventional flow soldering techniques.
  • a screw (not shown) can be screwed into hole through printed circuit board 24 to main the connector in position on the printed circuit board during the flow-soldering operation.
  • integrated circuit IC is electrically connected with contacts C by inserting contact members 21 into respective cavities 11 with beveled surfaces 8 and '12 acting as guide means to guide contact members 21 within cavities 11.
  • Surfaces 14b are provided to preclude any hang-up between the sharp sheared ends of contact members 21 and housing H.
  • beveled surfaces 12 are higher than beveled surfaces 8 so that contact members 21 are guided thereby within cavities 1'1. Beveled surfaces '12 and 8 therefore properly guide contact members 21 into respective cavities 21 if there is any misalignment of contact members 21.
  • Opposing beveled surfaces 12. of each of cavities 11 also receive respective tapered surfaces 21a of each of contact members 21, as illustrated in FIG.
  • Integrated circuit IC rests on the top surfaces of sides 3 and the channels of base 1 on each side of central section 4 permit ventilation of integrated circuit IC and central section 4 can be provided with openings, if desired, to permit flowing of air entirely along base 1.
  • Bulbous sections 18 of electrical contact C defines an anti-wicking means to prevent wicking of the solder up onto the contact elements 19.
  • the connector can be mounted onto a mounting board via a screw into hole 5 with posts 17 extending through openings in the mounting panel and conductor means can be connected to posts 17 via soldering or in any other well known manner. While cavities '11 have been disclosed as being provided in contact-carrying members 2, cavities 11 can, of course, be provided in sides 3 with members 2 being latched into position via latching members -6 and latching areas 16 to maintain the electrical contacts C in position in the cavities. Obversely, the ends of members 2 may be provided with latching members 6 and base 1 with latching areas 16.
