Definitions

  • a connector block for a cathode ray tube is made in dished form with channels along its outside. Components, such as resistors, can lie in these channels connected to sockets in the base of the block into which pins of the cathode ray tube are plugged.
  • This invention relates to electrical connector insulating housings for, electron tubes and in particular to electrical connector insulating housings for cathode ray tubes.
  • An object of the present invention is to provide an electrical connector insulating housing having an opening at one end for receiving the end of an electron tube and at its opposite end a plurality of cavities formed on the outside of the housing for receiving terminals attached to conductors, a side of each cavity having an aperture for admitting a pin of the electron tube into the cavity for engagement with the terminals, each cavity communicating with a channel defined by pairs of ribs extending along the outside of the housing for receiving an electrical component.
  • the housing is of substantially frusto-conical configuration, the opening being at the larger end of the housing.
  • a further object is that the opening is provided with an outwardly extending peripheral flange, key hole slots being formed in the flange between pairs of adjacent ribs defining the channels into each of which key hole slots a conductor attached to a component can be fitted.
  • an additional object is that the smaller end of the housing may be provided with a locating slot arranged to cooperate with a locating tongue on the terminal member of an electron tube to ensure correct orientation of the tube relative to the housing.
  • the housing is preferably provided with an aperture between two adjacent pairs of ribs through which the tab can project for connection with a grounding receptacle connector.
  • the cavities may be formed with shoulders for retaining the terminals within the cavities.
  • FIG. 1 is a rear plan view of the housing of the connector partly in section on the lines II of FIG. 2;
  • FIG. 2 is a side view of the housing partly in cross section on the lines II-II of FIG. 1, with a terminal and component in position and indicating the position of an electron tube;
  • FIG. 3 is an elevation of a terminal for use in the housing of FIG. 1;
  • FIG. 4 is a side view of a modified connector for accepting a grounding tab.
  • the housing 1 shown in FIGS. 1 and 2 is a one-piece molding of hard plastic material of generally frustoconical configuration.
  • the front, larger end of the housing 1 is open and the rear, smaller end has an inturned annular flange 2 formed with eight equally-spaced radial cavities '3.
  • a central aperture 4 in the flange 2 is provided with a locating slot 5 arranged between two adjacent cavities 3.
  • the cavities 3 are closed by a wall member 6 on their radially inner ends and they are open at their outer ends to lead into the ends of channels 7 formed by pairs of parallel ribs 8 extending along the outside of the housing 1.
  • the front open end of the housing 1 terminates in an outwardly-projecting radial flange 9 provided with key hole slots 10 arranged at the ends of the respective channels 7.
  • Each cavity 3 is closed at its rear end by a wall part 11 having a pair of radial slots 12 formed therein.
  • the front ends of the cavities 3 are each provided with a central slot 15 bounded by two parallel wall parts 16, 17.
  • Each wall part 16, 17 has an internally formed projection or shoulder 18, 19 respectively formed near its end adjacent the corresponding channel 7 and having a tapered part for guiding a terminal 20' into the cavity 3.
  • the terminal 20 comprises a ferrule 21 for crimping to a Wire and a receptacle comprising a flat base 22 having two inturned and converging side walls 23, 24 bent up from its edges.
  • the ends of the side walls 23, 24 are turned outwardly at 25, 26 respectively and each side wall has a respective forward extension 27, 28.
  • the extensions 27, 28 are each formed with an indent 29, the indents being arranged to embrace a pin of the tube fitted between the extensions 27, 28.
  • Terminals 20 are connected to conductors or components of the apparatus in which they are used prior to assembly within housing 1.
  • Each terminal 20 is fitted into a cavity 3 as shown in FIGS. 2 and 4 with the base 22 against the wall part 11 and the outwardly turned edges 25, 26 resting on the Wall parts 16, 17 and latching behind the shoulders 18, 19.
  • the indents 29 are in alignment with the slot 15.
  • a cathode ray tube 30 is connected at its base to a terminal member 31 having eight contact pins 32 projecting axially from it and arranged on a circle around a central boss 33 of insulating material.
  • the front end of the housing is passed over the rear of the boss 33 and aligned so that the boss 33 passes through the central aperture 4 with a locating tongue (not shown) on the boss engaging in slot 5.
  • the pins 32 are thus 9 aligned with the slots and the indents 29 of the terminals in cavities 3.
  • the pins 32 are forced between extensions 27, 28 springing them apart to make good electrical wiping contact.
  • one end of a resistor 34 is connected to terminal 20 by a short length of conductor 35 to which the ferrule 21 is crimped.
  • a conductor 36 at the ther end of the resistor 34 is spliced at 37 to a conductor 38 leading to other parts of the apparatus.
  • the resistor 34 is contained in the channel 7 between the two ribs 8 leading from the cavity 3 and the conductor 38 is anchored to the housing by pressing it into the key hole slot 10 in the flange 9 at the end of the channel 7. In this way, termial 20, resistor34, conductors 35, 36, 38 and splice 37 are properly insulated.
  • This slot 10 not only firmly anchors conductor 38 but also assists in retaining the resistor 34 in the channel.
  • terminals 20 will necessarily be connected to a component such as a resistor 34 in their respective channels 7 and in these cases the conductor crimped to the ferrule of the terminal can be made to lie in the channel 7 and be retained in slot 10. In this way, conductors of the connector can be neatly anchored all around the connector.
  • the housing does not add to the depth of the tube. This feature can be extremely important in television receivers where the depth of the receiver is to be kept to a minimum and is determined mainly by the depth of the cathode ray tube. If test probes are to be made to the pins of the tube, this can be done without removing the connector and while the tube is operational by inserting the probes into a slot 12 to contact the base 22 of the terminal connected to the appropriate pin.
  • the wall part 11 can be molded with a suitable designation. The distance between terminals is sufficient, by virtue of the enclosed nature of the cavities 3, to avoid tracking between terminals.
  • an aperture or slot 39 can be formed in the wall of the housing, as shown in FIG. 4, so that a tab 40 extending from terminal member 31 can project outside the housing between pairs of ribs 8.
  • a mating receptacle 41 secured to a ground lead 42 can then easily be mated to the tab 40.
  • the connector housing is a one-piece molding
  • the housing can comprise a plurality of molded parts connected together by, for example, screws.
  • the rear ends of the cavities 3 can be closed by a disc similar to wall part 11, the disc having radial slots 12 formed therein and holes through which screws can be threaded for attaching the disc to the end of the housing. Pillars can be provided between pairs of ribs for receiving the shanks of the screws.
  • An electrical connector insulating housing comprising one end having an opening for receiving an end of an electron tube and an opposite end provided witha plurality of cavities on an outside area of the housing for receiving terminals attachedto' conductors, aside of each cavity having an aperture for admitting a pin of the electron tube into the cavity for engagement with the terminals, each cavity communicating with a channel defined by pairs of ribs extending along the outside area of the housing for receiving an electrical component, the housing being of substantially frusto-conical configuration and having a continuously sloping outer surface, the opening being at a larger end of the housing.
  • each cavity is formed with a pair of shoulders for retaining the terminals within the cavities.
  • An electrical connector insulating housing for an electron tube comprising a hollow shell open at One end for receiving the end of the electron tube and having a wall member at the opposite end, a first pair of ribs formed externally on a side surface of the shell and extending forwardly towards the open end, a second pair of ribs formed externally of the wall member, the second pair of ribs defining with the wall member a cavity for receiving a terminal attached to a conductor, the cavity communicating with an elongate channel defined by the first pair of ribs, a through aperture in the wall member for permitting a pin of the electron tube to pass from the interior of the shell through the wall member into the cavity for electrical contact with the terminal when the References Cited UNITED STATES PATENTS 1,639,310 8/19 27 Richardson 17460 2,774,949 12/1956 Cardani et a1.
