Definitions

  • An electrical connector mounting arrangement which constitutes a mounting panel having openings extending therethrough, at least some of the openings provided with inwardly-directed protrusions, an electrical connector including a dielectric housing and electrical terminals disposed in passageways in the housing corresponding to the number of panel openings, section of the terminals extending outwardly from one end of the housing, projections extending outwardly from the one end of the housing and surrounding portions of the sections of the terminals, the housing being positioned on the mounting panel with the one end disposed thereagainst, the projections being disposed within the panel openings and the openings having the protrusions bitingly engaging the projections therein thereby maintaining the connector in position on the panel.
  • This invention relates to an electrical connector mounting arrangement for mounting an electrical connector onto a mounting panel and more particularly to a mounting arrangement for mounting a printed circuit connector to a pre-drilled panel without the use of mounting hardware.
  • An object of the present invention is to provide an electrical connector mounting arrangement which obviates the drawbacks of existing mounting arrangements.
  • Another object of the invention is the provision of a mounting panel having openings therethrough in which sections of terminals in a connector housing are disposed and means being provided in at least some of the openings and on the housing securing the connector housing in position on the mounting panel.
  • a further object is to provide projections of. a con- 3,466,589 Patented Sept. 9,, 1969 nector housing surrounding sections of electrical terminals extending outwardly frornt he connector housing, these projections mating with corresponding openings in a mounting panel with some of the openings having protrusion's to bitingly engage the projections thereby forming an interference-fit therebetween.
  • An additional object of the invention is the provision of grounding means to ground some of the terminals in the housing with the metallic mounting plate.
  • FIGURE 1 is an exploded perspective view of an electrical connector, mounting member and grounding means
  • FIGURE 2 is a partial perspective view of one opening in the mounting member
  • FIGURE 3 is a view taken along lines 33 of FIG- URE 2 with the part of the electrical connector secured in position therein;
  • FIGURE 4 is a perspective view of the grounding means
  • FIGURE 5 is a view taken along lines 5-5 of FIG URE 7;
  • FIGURE 6 is a view taken along lines 6-6 of FIG- URE 5 with the grounding means partially in position;
  • FIGURE 7 is a view similar to FIGURE 6 with the grounding means in position.
  • an electrical connector EC which comprises a dielectric housing I having electrical terminals 2 positioned in passageways 3 of housing 1.
  • Electrical terminals 2 are preferably secured in passageways 3 in accordance with the teaching set forth in US. patent application, Ser. No. 613,966, filed Feb. 3, 1967, but, of course, the terminals can be secured in position in the passageways in any desirable manner.
  • Electrical terminals 2 include posts 4 that extend outwardly from rear surface 5 of housing 1.
  • Projections 6 extend outwardly from rear surface 5 of housing 1 as part of the housing. The projections surround sections of most of posts 4 adjacent rear surface 5.
  • Dielectric housing 1 is made from any suitable dielectric material which contains good memory characteristics. Projections may be provided for every post, depending upon the application.
  • Mounting member 7 is a metallic mounting member and it has openings 8 corresponding to the number of posts 4 of electrical terminals ZYOpenings 8 have a configuration corresponding to the configuration of projec tions 6 and a clearance fit is provided therebetween, projections 6 having a length equal to or greater than the thickness of member 7.
  • Selected openings 8 have protrusions 9 formed therein at the inner ends thereof opposite the ends into which projections 6 are inserted into the openings.
  • protrusions 9 on the inner ends of openings 8 facilitates the insertion of projection 6 within the openings containing these protrusions and obviates channeling the projections along substantially the full lengths thereof if protrusions 9 were located at the insertion entrances to openings 8.
  • the memory characteristics of the material of the dielectric housing causes projections 6 in the areas of protrusions 9 to flow therearound, as illustrated in FIGURE 3, thereby tightly securing projections 6 in position in the openings containing these protrusions.
  • protrusions may be disposed at the insertion entrances to openings 8 instead of at the inner ends and protrusions may be disposed at both ends of the openings but oifset from each other.
  • Protrusions 9 are readily formed in selected openings 8 by means of a special punch that fits the openings and is provided with projections to disrupt the area surrounding the openings thereby forming protrusions 9.
  • the protrusions formed in the selected openings are formed in accordance with a balanced arrangement in order to preclude misalignment of posts 4 when protrusions 9 dig into projections 6.
  • mounting member 7 is a metallic member
  • a grounding collar is utilized for this purpose and is inserted within an opening 8 which contains no protrusions 9 and a shorter projection 6a.
  • Grounding collar 10 comprises an annular member 11 conforming to the configuration of opening 8 and is of such diameter so as to frictionally engage same.
  • Grooves 12 are formed in an exterior surface of annular member 11 to increase metal to metal intimacy with opening 8.
  • Opposed pairs of spring fingers 13 are disposed internally of annular member 11 and they are directed toward the axis of grounding collar 10.
  • One pair of spring fingers 13 makes spring contact with the narrow edges of a post whether the post is truly centered or off-center due to tolerance build-up.
  • the other pair of spring fingers aids automated assembly of the grounding collars in position in the mounting member as well as to prevent the post from being moved too far out of alignment when lateral forces are applied thereto.
  • Arcuate depressions 14 are disposed in the free ends of spring fingers 13 and may or may not assist in the electrical engagement with the edges of post 4.
  • Grooves 12 provide sharp edges so as to scrub the surfaces of openings 8 in order to make a good electrical connection therewith, especially if the openings have a chemical conversion coating or if the mounting member is made of aluminum to scrape through the aluminum oxide coating.
  • Grounding collar 10 therefore effects electrical grounding of selected wire posts to the mounting member without sacrificing a connection position on the posts in view of the grounding collar being disposed within the opening and thereby being flush with the surface of the mounting member adjacent thereto. Grounding collar 10 also may help to hold the post in position within the openings of the mounting member.
  • the present invention can be used in conjunction with mounting an electrical connector in openings in a mounting member wherein projections 6 of the dielectric housing surround sections of all of the electrical terminals and selected ones of the openings in the mounting member are provided with protrusions to bitingly engage corresponding projections of the dielectric housing to secure the electrical connector in position on the mounting member.
  • the invention is also directed to the use of a grounding collar to electrically ground selected posts to the mounting member.
  • An electrical connector mounting arrangement comprising a mounting panel having openings extending therethrough, at least some of the openings provided with inwardly-directed deformed protrusions formed of the material defining the openings, an electrical connector including a dielectric housing and electrical terminals disposed in at least some of passageways in the housing, sections of the terminals extending outwardly from one end of the housing, projections extending outwardly from the one end of the housing and surrounding portions of the sections of the terminals, the housing being positioned on the mounting panel with the one end disposed adjacent thereto, said projections being disposed within corresponding panel openings with said openings having said protrusions bitingly engaging the projections therein thereby maintaining the connector in position on the panel.
  • grounding means is disposed in some of said openings in tight and electrical engagement therewith, said grounding means including spring finger means electrically engaging the sections.
  • a mounting member having openings disposed therein, some of said openings provided with deformed protrusions directed toward axes thereof and formed of the material defining the openings
  • an electrical connector including a dielectric housing and electrical terminals, said housing having passageways in at least some of which said terminals are disposed and projections extending outwardly from one surface thereof, said terminals having sections extending outwardly from the one surface of said housing with the projections extending partially therealong, said projections disposed in corresponding ones of said openings with said one surface being disposed adjacent one side of said mounting member, said protrusions of the openings bitingly engaging said projections without misaligning said sections of said terminals thereby securing said electrical connector in position on said mounting member and insulated therefrom by said projections and with said sections extending outwardly from the other side of said mounting member.
