  • the known socket members are provided with no integral mounting means so that the socket members can be readily mounted on a reflector plate or suitable mounting member, except with the use of separate means or tools.
  • the primary object of the invention is to provide a one-piece socket member having integral mounting means thereon.
  • Another object of the present invention is the provision of the socket member having contact members which are readily placed in position therein, as well as removable therefrom.
  • a further object of the present invention is to provide a socket member which is durable and strong, which cannot be easily broken, and provides a stable mounting for fluorescent tubes mounted therein to protect same from vibration or mechanical shocks.
  • FIGURE 1 is an exploded perspective view of socket members and a contact member for insertion therein;
  • FIGURE 2 is a front elevational view of a socket member with contact members exploded therefrom;
  • FIGURE 3 is a cross-sectional view of a socket member mounted on a mounting member and with a contact member and fluorescent tube exploded therefrom;
  • FIGURE 4 is a rear elevational view, partially in section, of a socket member showing the contact member in place therein.
  • socket member 1 is molded from a suitable plastic material having stiff but flexible characteristics such as, for example, nylon, phenolic or the like, and comprises a tube or lightsupporting section 2, contact-supporting section 3 and mounting arms 4.
  • Tube-supporting section 2 is a tubular member having a configuration conforming to that of the end of a fluorescent tube 5 for receiving the end of the fluorescent tube thereinto.
  • Wall 6 separates tube-supporting section 2 from contact-supporting section 3, and holes 7 extend through Wall 6 for receiving contact pins 8' (only one being shown in FIGURE 3) of fluorescent tube 5.
  • Contact-supporting section 3 comprises cavities 9 which are disposed substantially normal to section 2, and each cavity is in communication with the interior of tubesupporting section 2 via respective holes 7.
  • Projections 10 are located in each cavity at the juncture of each sidewall and the rear wall thereof.
  • An opening 11 is located in the bottom of each cavity in alignment with projections 10.
  • An arcuate-shaped extension 12 extends outwardly from the rear wall of contact-supporting section 3 and has a hole 13 extending therethrough.
  • Mounting arms 4 extend outwardly from sections 2 and 3 at a slight angle from section 3 and in alignment with section 3.
  • Each arm has a transverse slot 14 proximate its outer free end, and the free end includes a beveled surface 15.
  • Arms 4 have stiflly-flexible characteristics and resist being pushed toward contact-supporting section 3 so that they retain their normal angular disposition.
  • the upper surface of slot 14 adjacent beveled surface 15 extends outwardly further than the bottom surface in order to provide additional holding area.
  • each contact member includes a ferrule portion 17 and a contact portion 18.
  • Ferrule portion 17 has a section crimped onto the conductive portion of insulated lead 19 and another portion crimped onto the insulation thereof.
  • insulated lead 19 may be connected to contact member 16 in any desirable manner other than crimping, but the crimping method is the preferred method.
  • Contact portion 18 extends outwardly from ferrule portion 17 and has a U-shaped configuration with the legs inclined slightly toward each other. The base portion of the contact portion is substantially flat and has a hole 20 extending therethrough. Each leg of U-shaped contact portion 18 has a section sheared therefrom in an outward direction, which is defined as a lance member 21.
  • contact members 16 are inserted in respective cavities 9, and each contact member is pushed into its cavity until lance members 21 snap into position behind projections 10, at which point hole 20 in the contact member is in alignment with a respective hole 7 in wall 6.
  • the contact member With lance members 21 resiliently seated against projections 10, the contact member is locked in position in its cavity since lance members 21 in engagement with projections 10 prevent the contact member from being withdrawn from the cavity, and the leading end of the contact member leading directly toward the bottom of the cavity opposite opening 11 limits the inner movement of the contact member within the cavity.
  • edges of projections 10, which are directed toward the open end of cavity 9, are preferably beveled so as to facilitate the movement of lance members 21 thereby until they reach their locked position on the other sides of the projections.
  • the spring characteristics of the legs of contact portion 18 maintain lance members 21 in locking alignment with projections 10.
  • a suitable bifurcated tool (not shown) is inserted within the respective opening 11 and in engagement with the lance members. Upon movement of the tool against projections 10, the lance members are moved free of projections 10; and, upon force being applied to the lead, the contact member is removed from the cavity.
  • the socket members are disposed on the ends of fluorescent tube 5 with tube-supporting sections 2 surrounding the ends thereof and contact pins 8 extending through holes 7 in engagement with respective contact members 16.
  • Mounting arms 4 on each socket member are pushed toward the contact-supporting sections, and the free ends of these mounting arms are inserted within openings 22 and in mounting member 23 with beveled surfaces 15 facilitating the insertion of arms 4 within openings 22.
  • the mounting arms are released to spring back toward their normal position, and slots 14 engage the edges of openings 22 to lock the socket members in position on the mounting member.
  • a hole can be disposed in mounting member 23 adjacent openings 22 and in alignment with holes 13 so that a screw or similar securing means can be placed in holes 13 and their aligned holes in mounting member 23 to provide additional securing means for the socket members, although mountingarms 4 will provide the necessary lockin g pressure to maintain the socket members in position on the mounting member.
  • socket members provide a stable mounting for fluorescent tubes and the like, and they are not subject to normal or above-normal vibration or mechanical shock.
  • the contact pins in engaging the legs of the contact members provide a wiping action therebetween, thereby breaking down the oxides therebetween to provide an excellent mechanical and electrical connection.
  • a onepiece socket member having a tube-supporting section, contact supporting section, and stifily-flexible mounting arms for mounting a fluorescent tube onto a suitable mounting member and wherein contact members are readily placed in and removed from the contact-supporting section.
  • Socket means for supporting ends of a fluorescent tube and for mounting in openings of a mounting member, said socket means comprising tube-supporting sections for receiving the ends of the fluorescent tube therein, contact-carrying sections located at the inner ends of said tube-supporting sections and extending substantially normal thereto, said contact-carrying sections defining a Wall at the juncture between said sections and holes in communication with said sections, contact members removably mounted in said contact-carrying sections and having openings in communication with said holes so that contact pins of said fluorescent tube pass through said holes and openings for engagement with said contact members, stiflly-flexible mounting arms extending laterally from said sections and for disposition in said opening and means on said mounting arms for engaging said mounting member with said stifily-flexible mounting arms resiliently maintaining said means in engagement with said mounting member.
