  • the upper and lower body parts retain the forces generated by the action of inserting the plug and removing the plug.
  • the pins are carried by a common chassis.
  • the manually operable button is provided with splines engageable with slots in the chassis, following partial rotation of the button.
  • inclined surfaces are provided to achieve partial rotation.
  • An earth wire and a neutral wire are crimped directly to corresponding spring contacts.
  • a live wire is crimped to a fuse clip, which in turn connects to a mains fuse, and the fuse then attaches to a spring contact.
  • the mains fuse mounted in the fuse carrier, is accessible from the outside.
  • the upper and lower body parts are secured together by tamper resistant security screws.
  • the upper and lower body parts are resiliently secured together using springs.
  • the plug, or adaptor incorporates an integral electrical transformer.
  • a plug, or adaptor, that includes an electrical transformer also has a low voltage two core or three core cable.
  • An interlock is provided between the earth pin deployment and the ability to connect the plug, or adaptor, to mains power.
  • a live contact is mounted on or acted upon by a sliding carriage which moves the live contact, against spring bias, from an inactive position to an active position when the earth pin is moved from its inactive position to its active position.
  • Figure 1 is a front elevation of a first embodiment of three pin plug in accordance with the invention with the pins in their inactive positions;
  • Figure 2 is a plan view of Figure 1 ;
  • Figure 3 is a side elevation of Figure 1;

  • Figures 11 and 12 detail the interlock feature in both active and inactive positions; and Figure 13 illustrates a sectional view through the resiliently mounted lower body part.
  • an upper body part 1 is secured to a lower body part 2 by screws 10.
  • Live, neutral and earth pins are indicated at 4, 5 and 6 whilst a cable strain relief extension is indicated at 9 and a fuse carrier at 11.
  • electrical spring contacts are indicated at 7 and a crimp plate at 8.
  • a manually displaceable movable part of a locking mechanism 3 has a blind circular bore 12 in which is located a coil compressor spring 18 engaged by an end of a plunger 13 extending from the upper body part 2.
  • a user- operable button 14 extends through an aperture 15 in sidewalls 16 of the upper and lower body parts 1 , 2, and is connected to the movable part of the locking mechanism 3 so that movement of button 14 axially displaces the movable part of the locking mechanism 3, as indicated by arrow 17, firstly to release the pin 6 from the inactive, storage position illustrated in Figures 1-4 to permit the pins 4, 5 and 6 to be rotated by the user to the deployed or active positions indicated in Figures 5 to 8, with the user then releasing the button 14 to permit the coil compressor spring 18 to displace the movable part of the locking mechanism 3 once again to its locking position in which it re-engages the pin 6, as shown in Figure 8.
  • the locking mechanism 3 has movable and static parts.
  • the static parts of the mechanism are those which are fixed directly or indirectly to the upper body part.
  • the movable parts of the mechanism are those parts that can be displaced relative to the upper body part and against a spring bias.
  • the movable part(s) has a first face 3A, and a second face 3B.
  • the user displaces button 14, as indicated by arrow 17, to raise the movable part of the locking mechanism 3 from its Figure 4 position, to permit the user to effect (anti-clockwise) rotation of the pin 6 to its Figure 8 position, at which time the user releases the button 14, so that the spring 18 may displace the movable part of the locking mechanism 3 downwardly and again into its locking position, this time with the first face 3A proximate face 6B of the pin 6, and the second face 3B engaging face 6C of the pin 6.
  • a “sliding pin” embodiment is illustrated in Figure 8 and 9.
  • all three pins 4, 5 and 6 are mounted on a common slide chassis 19, under the control of a user-operable release button 14A with the movable part of the locking mechanism 3A, capable, in this embodiment, of both axial and rotational movement as indicated by arrows 17, the rotational movement bringing a pair of 180° opposed splines 20 into slots 21 of the chassis 19.
  • buttons 14A To move the pins 4, 5, 6 from the active to inactive position, the user presses on an exposed end 26 of button 14A which end 26 projects through the aperture 15 in the upper body part 1 , so that under surfaces 27 of the movable part of the locking mechanism 3A move down and round circular, inclined surfaces 23 on the lower body part 2.
  • the resultant partial rotation of the button 14A aligns splines 20 of the movable part of the locking mechanism 3A with slots 21 and releases the pins 4, 5, 6 so that they can be pushed by the user in to the upper body part 1 and lower body part 2. Once the pins have been partially pressed inward, user pressure on the button 14A may be released.
  • the upper surfaces 27A of the movable part of the locking mechanism 14A cannot return to the original position until the pins 4, 5, 6 and chassis 19 are pressed fully inward by the user and the engagement of the splines 20 in the slots 21 is lost. Once the chassis 19 is pushed fully into the plug body, the chassis 19 will clear the splines 20, which will allow the locking plate 14A to ride up and round the inclined surfaces 23 and rotate out of alignment. By moving out of alignment with the slots 21 , the splines 20, together with the central spring 18, hold the chassis 19 and pins 4, 5, 6 in the closed position.
  • the movable part of the locking mechanism 3A cannot return to its original position until the pins 4, 5, 6 and chassis 19 are pulled fully outward by the user and the engagement of the splines 20 in the slots 21 is lost. Once the pins 4, 5, 6 and chassis 19 are pulled fully out of the plug body, the chassis 19 will clear the splines 20, which will allow the upper surface 27A of the movable part of the locking mechanism 14A to ride up and round inclined surfaces 23 and rotate out of alignment. Once the slots 21 and the splines 20 are out of alignment with each other, the movable part of the locking mechanism 14A, together with the upper body part 1 and coil spring 18, hold the pins 4, 5, 6 in the open position.
  • a coin slot 26 is provided in the button of the movable part of the locking mechanism. This allows the user to further rotate the movable part of the locking mechnism into a locked position. In this position, pressure on the button 14A does not cause it to rotate.
  • An optional safety feature of the pivoted pin embodiment is the inclusion of an interlock between the earth pin deployment 6 and the connection of the live pin 4 to the mains supply through the live contact 7A.
  • the live contact 7A is mounted on or acted upon by a sliding carriage 28.
  • the sliding carriage 28 moves in the direction shown by arrow 29 and displaces the live contact 7A, against its spring bias, from an inactive position to an active position when the earth pin 6 is moved from its inactive position to its active position.
  • the live contact 7A may touch the blade on the top of the live pin 4, when the live pin 4 is in its active position or is moved into its active position.
  • the sliding carriage 28 and the live contact 7A are moved back to their inactive position by the live contact spring bias.
  • the final example, shown in Figure 13, is where the lower body 2 and the pins (4, 5 and 6) comprise the movable part of the locking mechanism and the upper body 1 , contains the static parts of the locking mechanism 3B.
  • the lower body 2 is resiliency attached to and displaceable from the upper body 1 by inserting a compression spring 18 coaxially over fixing screws 10 between the upper body 1 and lower body 2, and trapping the springs between the screw head 10 and an underside of the lower body part 2.
  • the moveable part(s) of the locking mechanism 3 are displaced relative to the upper body 1 when the users manually moves button 14 in the direction of arrow 17, to displace the lower body 2 from the static parts 3B of the clamping mechanism which are fixed to the upper body 1.
  • This displacement unlocks the pins (4, 5 and 6) and allows them to be moved from the active to inactive position or vice versa, as desired by the user, with release of the lever or button 14 by the user permitting spring loaded displacement of the movable part(s) of the locking mechanism 3 until the latter re-engages and locks the pin(s) in its new position.
  • the static part(s) has a first face 3A, and a second face 3B. As shown in Figure13, in the active position of the pins 4 and 5, only the second engagement face 3B is employed, by abutting the movable part on the face portion 4B and 5B of the line and neutral pins 4 and 5.
