  • Secondary unit locks 147 (shown in FIGS. 9 , 10 and 14 ) comprise latches, bars or other structures operably coupled to shaft 142 so as to move, in response to rotation of shaft 142 , between a locking state in which the unit 124 is locked or retained relative to enclosure 122 when in the enclosure 122 and an unlocked state.
  • locks 147 comprise projections fixed to shaft 142 and extending from shaft 142 .
  • Secondary unit locks 147 include both a front lock 147 (shown in FIG. 14 ) and a rear lock 147 (shown in FIG. 9 ). As shown by FIG. 9 and in broken lines in FIG.
  • locks 147 are contained within or do not sufficiently project beyond unit 124 to interact with enclosure 22 . As shown by FIGS. 12 and 14 , in the locked state or position, locks 147 sufficiently project beyond unit 124 so as to extend into corresponding receiving slots or openings 240 (one of which is shown in FIG. 14 ) to inhibit or prevent movement and withdrawal of unit 124 from enclosure 122 . In addition to retaining unit 124 in enclosure 122 , locks 147 additionally provide a path for shock and loads instead of such loads and shocks extending through connection components 140 and 130 .
  • secondary locks 147 When unit 124 is withdrawn or removed from enclosure 122 , secondary locks 147 further prevent or inhibit insertion of unit 124 into enclosure 122 when connector component 140 is inadvertently in the extended position, further inhibiting accidental damage to connector component 140 . In other embodiments, one or both of secondary locks 147 may be omitted.
  • FIGS. 4 , 5 , 6 and 8 - 13 further illustrate an example process or method by which unit 124 is inserted into and connected to enclosure 122 .
  • unit 124 is inserted into enclosure 122 by being moved in the direction indicated by arrow 160 .
  • FIGS. 8-11 such insertion continues until end 220 of plunger 202 physically contacts surface 128 of enclosure 122 .
  • connector component 140 is or is moved into sufficient proximity or alignment with connector component 130 of enclosure 122 for subsequent connection to connector component 130 .
  • plunger 202 moves from the state shown in FIG. 6 to the state shown in FIG. 10 against bias 206 , whereby projection 204 is relocated from axial portion 224 into circumferential portion 226 of slot 218 , allowing shaft 142 to be rotated. As shown by FIGS.
  • rotational lockout mechanism 146 once rotational lockout mechanism 146 has been activated to an unlocked state as a result of the mechanical reaction between plunger 202 and surface 28 , shaft 142 is rotated about its axis 148 to generate circular motion and torque, Rotation to translation coupler 144 converts the rotational motion and torque provided by the rotation of shaft 142 to linear translational motion so as to move connector component 140 in the direction indicated by arrow 164 , perpendicular to direction 160 and axis 148 , from a recessed or retracted position to a projecting or extended position and into connection or contact with connector component 130 .
  • rotational lockout mechanism 146 potentially inhibits or prevents rotation of shaft 142 and therefore prevents or inhibits extension of connector component 140 until connector component 140 is sufficiently proximate to an aligned with connector component 130 , rotational lockout mechanism 146 reduces the likelihood of accidental damage to connector components 140 and 130 , which might otherwise result from premature attempted connection of such components.
  • the alignment indication provided by rotational lockout mechanism 146 offers enhanced protection against accidental damage to connection components 130 , 140 during an attempted connection.
  • Disconnection and withdrawal of unit 124 from enclosure 122 occurs by sequencing through the above-mentioned steps into an opposite manner.
  • shaft 142 is rotated, moving or allowing connector component 140 to move to the retracted or recessed position in which component 140 is disconnected from component 130 .
  • unit 124 is withdrawn from enclosure 122 .
