Definitions

  • An electron tube connector comprises a one-piece dielectric housing having a series of cavities surrounding an aperture and provided with channels, the channels extend outwardly from each of the series of cavities at an angle with respect to a plane extending through an axis of each of the series of cavities and a longitudinal axis of the housing so that conductors connected to terminals disposed in the cavities can be directed toward one end of the housing to bunch the conductors thereat.
  • This invention relates to an electrical connector and more particularly to an electrical connector for use on electron tubes.
  • the electrical connectors presently in use especially for cathode ray tubes, have the terminal members therein bent at right angles with respect to the insertion axis of the electrical connectors. Such an arrangement increases the size of the electrical connectors.
  • the electrical conductors connected to the terminal members extend outwardly from the electrical connector in a radial direction in some applications and in other applications 7 the portions of the electrical terminals and the electrical conductors connected thereto extend outwardly from the electrical connector parallel to the insertion axis of the electrical connector.
  • An object of the invention is to provide an electron tube electrical connector which saves space and permits the electrical conductors connected to the electrial terminals to be readily bunched.
  • Another object of the invention is to provide an electron tube electrical connector having sections of the electrical terminals connected to electrical conductors and the electrical conductors extending outwardly from the insertion axis in the same plane as that of the terminal housing.
  • Still another object of the invention is the provision of an electron'tube electrical connector having a unitary terminal housing.
  • a further object of the invention is to provide an electron tube electrical connector having electrical terminals that are readily insertable into and removable from a terminal housing.
  • An additional object of the invention is the provision of an electron tube electrical connector wherein the electrical conductors connected to the electrical terminals are directed outwardly from the terminal housing at an angle with respect to the insertion axis so that the electrical conductors can be readily bunched.
  • a still further object of the invention is to provide an electron tube electrical connector wherein the electrical terminals are completely insulated by the terminal hous mg.
  • Still an additional object of the invention is the provision of an electron tube electrical connector wherein the sections of the electrical terminals. connected to the electrical conductors are supported by the terminal housmg.
  • a further addiitonal object of the invention is to pro vide an electron tube electrical connector with the locking lances of the electrical terminals thereof facilitating engagement of these electrical terminals with electrical contacts with which they are to electrically engage.

  • FIG. 5 is a view taken along lines 55 of FIG. 4.
  • FIG. 6 is a plan view of an alternative embodiment of the electron tube connector.
  • Terminal housing 1 is made from a suitable dielectric material such as, for example, nylon, polyvinylchloride, polyethylene, polypropylene or the like and the terminal housing is formed as a one-piece housing in accordance with conventional molding techniques.
  • the terminal housing comprises a planar section 3 and a central section 4 integral with and extending outwardly from planar section 3.
  • An opening 5 extends through central 'section 4 and has a polarizing recess 6- disposed therein.
  • a series of triangular-shaped cavities 7 are disposed in central section 4 around opening 5.
  • a beveled and circular depression 8 is located at the entrance of each cavity 7 to facilitate the insertion of pins P of an electron tube ET within cavities 7.
  • Spaced projections 9 extend outwardly from planar section 3 and central section 4 at each of cavities 7.
  • the spaced projections for each cavity extend outwardly from the respective cavities at an angle with respect to a plane extending through an axis of each of the cavities and a longitudinal axis of the terminal housing. In the embodiment of FIG. 1, the spaced projections of one cavity extend toward the spaced projections of an adjacent cavity around the terminal housing.
  • Openings are located in central section 4 between the cavities 7 and spaced projections 9.
  • Each opening 10 communicates with triangular-shaped cavities 7 at the junction between two sides thereof.
  • spaced projections 9 associated with each of cavities 7 define a channel.
  • Apertures 11 extend through planar section 3 in communication with each of cavities 7 and in alignment with latching surfaces 12 located in each of cavities 7.
  • Electrical terminals 2 comprise a contact section 13 and a ferrule section 14.
  • the electrical terminals are susceptible to mass production by automatic machinery and are conveniently formed by shaping a sheet metal blank or strip of a suitable electrically conductive metal such as brass, bronze or the like in successive forming steps.
  • the metal is sufficiently hard and resilient to impart to contact section 13 a spring-like character, yet it is sufliciently malleable to permit cold-forging or crimping of ferrule section 14 onto a conductor 15 to provide an excellent mechanical and electrical connection.
  • Contact section 13 is connected to ferrule section 14 via transition section 16 so that the insertion axis of contact section 13 is disposed at right angles with respect to the axis of ferrule section 14 and this type of electrical terminal is commonly called a flag terminal.
  • contact section 13 has a triangular configuration and a locking lance 17 is struck out from one side of contact section 13 and preferably the free side thereof.
  • the electrical terminal Since the ferrule section of the electrical terminal is located at a right angle with respect to the contact section, the electrical terminal has a height no higher than the height of the contact section.

  • Locking lances 17 engage latching surfaces 12 in cavities 7 to secure the electrical terminals within the terminal housing. Since locking lances 17 are located at the entrances of contact sections 13, such an arrangement facilitates the insertion of pins P within contact sections 13.
  • a tool 18 is inserted within cavities 7 via apertures 11 in order to move locking lances 17 free of latching surfaces 12 so that the electrical terminals can be removed from the terminal housing.
  • Polarizing recess 6 mates with a polarizing projection (not shown) located on electron tube ET in order to assure the proper mating of pins P with respective electrical terminals 2.
  • the inner ends of the electrical terminals rest on planar section 3 which limits the movement of pins P within contact sections 13. If the conductors are moved out of the channels, transition sections 16 are strong enough to prevent any deformation of the electrical terminals.
  • Terminal housing 1 is a one-piece member and its height or depth is such to permit engagement with an electron tube in a space-saving manner.
  • the angular dispositions of the channels formed by spaced projections 9 direct conductors 15 toward a common conductor-bunching location at the periphery of terminal housing 1.
  • the channels formed by spaced projections 9 also provide support for ferrule sections 14 of electrical terminals 2.
  • Terminal housing 1 also completely insulates the electrical terminals.
