Definitions

  • the present invention relates to a two-part electrical connector in which one of the parts can be mounted in a wall.
  • the present invention has particular application for providing an electrical connection through a wall in a motor vehicle .
  • first part of an electrical connector in an aperture in the wall, and plug a second part of the electrical connector to the first part.
  • Each part of the connector defines a housing for electrical contacts which electrically connect on mating the first and second parts together.
  • the first part is secured in the aperture in the wall by passing the first part through the aperture until latching tangs snap fit with the wall around the opening, and then screw-threading a collar on to the first part. In areas where access is difficult, such an arrangement is difficult to install.
  • a two-part electrical connector in accordance with the present invention comprises a first part having a housing of electrically insulating material which is capable of installation in an aperture, of predetermined shape and size, in a wall of predetermined thickness, the housing having a first ring which extends substantially circumferentially around the housing, and a second ring which extends substantially circumferentially around the housing, the rings being axially spaced by a distance which is the same as or slightly more than the thickness of the wall, the first ring having a maximum diameter which is greater than the minimum diameter of the aperture, the second ring having a maximum diameter which is greater than the minimum diameter of the aperture but less than the maximum diameter of the aperture, and a minimum diameter which is less than the minimum diameter of the aperture.
  • the present invention overcomes the problems associated with the prior art connectors.
  • the two-part electrical connector 10 in accordance with the present invention, comprises the first part 12 which includes a housing 14 of electrically insulating material and which is substantially annular; and the second part (not shown) which includes a housing of electrically insulating material.
  • the first part 12 is capable of installation in an aperture 16 (of known shape and size) in a wall 18 (of known thickness).
  • the housing 14 of the first part 12 has a first ring 20 and a second ring 22. Both rings 20,22 extend substantially circumferentially around the housing 14 and are, in general, axially spaced with a predetermined separation which is the same as or slightly more than the thickness of the wall 18.
  • the first ring 20 has a maximum diameter D 1 ( Figure 3) which is greater than the minimum diameter A 1 of the aperture 16.
  • the second ring 22 has a maximum diameter D 2 which is greater than the minimum diameter A 1 of the aperture 16 but less than the maximum diameter A 2 of the aperture, and a minimum diameter D 3 which is less than the minimum diameter A 1 of the aperture.
  • the first part 12 is installed in the aperture 16 by passing the second ring 22 of the housing 14 through the aperture and then rotating the housing about its longitudinal axis X to trap a portion of the wall 18 between the first and second rings 20,22.
  • the rings and the aperture may be rectangular. However, in the preferred arrangement that is shown herein, the aperture 18 is substantially oval, the first ring 20 is substantially circular, and the second ring 22 is substantially oval in shape.
  • the first ring 20 preferably has one or more flexible legs 24 directed towards the second ring 22 to reduce the axial separation between the rings over a small circumferential distance.
  • the flexible leg or legs may be formed on the second ring and directed towards the first ring.
  • a notch 28 is preferably formed in the wall 18 which opens into the aperture 16.
  • the housing 14 has an axially extending external rib 25 which passes through the notch 28 during initial installation of the first part 12 in the aperture 16.
  • the second ring 22 has a lug 26 directed towards the first ring 20 which is formed on a resiliently flexible portion 30 of the second ring.
  • the lug 26 engages the wall 18 to deflect the flexible portion 30 away from the first ring 20.
  • the lug 26 reaches the notch 28, the lug snaps into the notch 28.
  • the engagement of the lug 26 in the notch 28 substantially prevents unintended rotation of the first part 12 after installation in the aperture 16. Intentional rotation is possible by manually pushing the flexible portion 30 to move the lug 26 out of the notch 28 to allow rotation of the housing 14.
  • the first part 12 includes a locking ring 32 which is substantially annular and which is positioned inside the housing 14.
  • the locking ring 32 is capable of axial movement relative to the housing 14, and is retained in the housing 14 by latches 34 which make a snap fit in axially extending apertures 36 in the housing.
  • a coil spring 38 is positioned inside the housing 14 adjacent the locking ring 32 and acts on the locking ring to bias the locking ring in an axial direction away from the housing.
  • the locking ring 32 has a flexible leg 40 positioned adjacent the flexible portion 30 on the housing 14.
  • the flexible leg 40 and the flexible portion 30 preferably have corresponding dimples 42,44 respectively which can contact one another.
  • the flexible leg of the locking ring 102 is replaced by an aperture 104.
  • the lug 26 is positioned in the notch 28 ( Figure 7) and the locking ring 102 is biased outwardly by the spring 38, the dimples 42,44 on the locking ring 102 and the flexible portion 30 of the housing 14 are positioned adjacent one another to substantially prevent movement of the flexible portion. In this position, the first part 12 cannot be removed from the aperture 16.
  • the locking ring 102 is manually pushed inwards against the bias of the spring 38 to bring the aperture 104 adjacent the dimple 44 on the flexible portion 30 ( Figure 8), and the flexible portion is then manually pushed radially inward.
  • the lug 26 is moved out of the notch 28 and the housing 14 can be rotated to remove the first part from the aperture 16 in the wall 18.
  • the present invention allows easy (one-handed) installation of the first part of a two-part electrical connector in an aperture in a wall.
  • the present invention can also provide a two-part connector in which the first part can be locked in the aperture, and, further, in which the locked first part can only be removed on when the second part is removed or when a locking ring is manually pushed.
