Definitions

  • the present invention relates to a universal electrical connector, of the type wherein one of the connector parts can be connected to another connector part identical in construction with itself. Each connector part can be converted to a male part, or plug, or a female part, or socket.
  • the connector of the invention is particularly adaptable to a co-axial transmission line which includes an inner and an outer conductor.
  • radio frequency leakage has heretofore been a serious problem, and attempts at preventing that leakage have not been entirely successful.
  • the outer tubular conductor presents a contact surface which extends through the perimeter of a great area and accordingly it has been difficult to establish perfect contact engagement between two such contact areas in the connected lines.
  • the invention substantially overcomes such difficulty by providing secure connection between those contacts surfaces, and uniform and accurate engagement throughout the areas thereof.
  • This feature of the invention is particularly advantageous in the case of an outer tubular conductor where the contact area extends to the limits of a great area.
  • An object of the invention is to provide a novel construction of connector in which the contact surface of the outer tubular conductor lies in a plane transverse to its axis, whereby to more effectively establish uniform and accurate contact engagement between the outer conductors of the connected parts.
  • Another and more specific object is to provide a connector of the foregoing general character made up of parts in which each part includes a male element projectable outwardly to active position and retractable inwardly to inactive position, and each part in capable of being connected in another connector part of identical construction, where, in one of the parts the male element is in active position and in the other part in inactive position.
  • An additional object is to provide a connector of the character just referred to in which the male element is in the form of a tubular sleeve surrounding the outer tubular conductor, and an actuator member is in the form of a nut surrounding the male element and thereby effective for establishing secure engagement with, and uniformly around, the male element of the opposite connector part, for thereby establishing uniform contact engagement between the contact areas of the conductors of the connector parts.
  • Still another object is to provide a connector of the character referred to in which when the male element is in retracted position it is entirely free of engagement with the actuator member whereby to enable unencumbered securement between the actuator member and male element of the cooperating connector part.
  • a still further object of the invention is to provide a connector of the foregoing character which is quickly and easily connected and disconnected.
  • FIGURE 1 is a view partially in section and partially in elevation showing a connector made according to the present invention and illustrating a stetp preliminary to the actual connecting operation;
  • FIGURE 2 is an exploded view of the elements making up the outer portion of one connector part
  • FIGURE 3 is a view showing the upper part of FIG- URE 1 and indicating a step of the connecting operation;
  • FIGURE 4 is a view similar to FIGURE 3 showing various elements in different positions;
  • FIGURE 5 is a view similar to FIGURES 3 and 4 showing various elements in other positions;
  • FIGURE 6 is a view similar to FIGURES 3, 4 and 5 showing various elements in still different positions.
  • FIGURE 7 is an end view of the central portion of a connector part, taken at line 77 of FIGURE 1.
  • FIGURE 1 showing a connector embodying the features of the present invention and including a pair of identical connector parts in position preliminary to the connecting operation. Since the connector parts are identical in construction in accordance with the main feature of the invention, a description of one of the parts will suffice for both and the various elements of the connector parts will be given identical reference numerals but identified as right and left in making reference to either as distinguished from the other.
  • the connector parts are indicated at 10 and each is connected to or mounted on a transmission line 12 which includes an inner conductor 14 and an outer tubular conductor 16 co-axial therewith.

  • the dielectric support is gripped between the shoulders 48 and 64 in the outer conductor and the shoulders and in the inner conductor.
  • the line of conduction in the inner conductor 14 is from the body 18 to the adapter 24 and contact adapter 36 to the contact surface 38 in the latter; in the outer conductor 16, it is from the body 43 t0 the connector body to the contact surface 61.
  • the coupler sleeve mounting 52 is in the form of a nut disposed exteriorly of the connector body 50, and includes an axially outer end portion having axial apertures 91 for receiving the pins of a spanner wrench for assembling the element in the coupling.
  • the enlarged portion 90 has a bore 92 inwardly of which is a shoulder 93.
  • Inwardly of the shoulder 93 is an internally threaded section 94 receiving the threaded section 76 and inwardly of this threaded section is a cylindrical bore 95 dimensioned for slidably receiving the surface 78 of the connector body 50, the inner end forming a shoulder 96.
  • the coupler sleeve mounting 52 is provided with an axial keyway 97 the ends of which form shoulders 98 and 99, the keyway receiving a key 100 fitted in the coupler sleeve or male element 54.
  • the latter has an inner reduced diameter portion 102 having an end surface 104 serving as a shoulder or abutment, a counter bore 106 and an axially outwardly facing shoulder 108 opposed to an inwardly facing shoulder 109 on the enlargement 90.
  • the coupler sleeve 54 has exterior threads 110 from adjacent its outer end inwardly a substantial extent.
  • the outer actuator member or nut 56 has a reduced portion 112 having a bore 114 receiving the connector body 50. This reduced portion has an axially inwardly facing shoulder 116 opposed to the shoulder 84 and adapted to engage the latter at times.
  • the nut 56 has a counter bore 118 defining an outwardly facing shoulder 120 adapted to engage the opposed facing end shoulder 96 of the coupler sleeve mounting 52. Adjacent the axially outer end of the bore 118 are internal threads 122 adapted to engage the threads 110 on the coupler sleeve 54 in a manner described hereinbelow.
  • the nut 56 has limited axial movement between the shoulders 84 and 96.
  • the coupler sleeve 54 has axial sliding movement, limited by the ends of the keyway 97.
  • the coupler sleeve 54 is worked outwardly or inwardly as limited by the keyway, as indicated.
