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.
  • a two-part electrical connector in accordance with the present invention comprises a first part having a housing of electrically insulating material and which is substantially annular; a second part having a housing of electrically insulating material and which makes a sliding fit inside the housing of the first part, the housing of the second part having a radially outwardly extending substantially rigid lug; a locking ring which is substantially annular and which is retained in the housing of the first part, the locking ring being capable of movement in an axial direction relative to the housing of the first part between a first position and a second position; a latching ring which is substantially annular and which is retained in the housing of the first part and is partially surrounded by the locking ring, the latching ring having a radially inwardly extending resilient latching tang which can be engaged by, and latches with, the lug on the housing of the second part on sliding the housing of the second part into the housing of the first part; and a spring acting on the locking ring to bias the locking ring towards the first position
  • 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 16 which includes a housing 18 of electrically insulating material.
  • the housing 18 of the second part 16 is mated with the housing 14 of the first part 12 by sliding the housing 18 inside the housing 14.
  • Each housing 14,18 has complementary electric contacts (not shown) secured therein which make electrical connections when the housings are mated together.
  • the connector 10 further includes a locking ring 20, a latching ring 22, a coil spring 24, and preferably a ring seal 26.
  • the locking ring 20 is substantially annular and has a number of radially outwardly directed resilient tabs 28 which make a sliding fit in corresponding grooves 30 formed in the inner surface 32 of the housing 14 of the first part 12 and then make a snap fit behind a shoulder 34 in the inner surface to latch the locking ring and the housing of the first part together.
  • the locking ring 20 is capable of moving in an axial direction A relative to the housing 14 of the first part between a first position in which the tabs 28 engage the shoulder 34 and a second position in which the tabs are axially spaced from the shoulder.
  • the coil spring 24 is positioned between the locking ring 20 and another internal shoulder (not shown) which is spaced from, and faces, the shoulder 34 inside the housing 14, and acts on the locking ring 20 to bias the locking ring into its first position and away from the housing 14 of the first part 12.
  • the locking ring 20 substantially surrounds the housing 18 of the second part 16.
  • the latching ring 22 is substantially annular and on assembly of the connector 10 is positioned between an internal shoulder 36 on the locking ring 20 and an internal shoulder (not shown) in the housing 14 of the first part 12.
  • the ring seal 26 is preferably positioned between the latching ring 22 and the housing 14 of the first part 12.
  • the latching ring 22 is surrounded partially by the locking ring 20 and partially by the coil spring 24.
  • the latching ring 22 substantially surrounds the housing 18 of the second part 16.
  • the latching ring 22 has a number of radially inwardly extending latching tangs 38 which are resiliently mounted at the free end 40 of axially extending resilient legs 42 positioned in apertures 44 in the latching ring.
  • the legs 42 are substantially U-shaped and connected to the remainder of the latching ring 22 at the ends 46 of the arms of the U. Other suitable shapes for the legs 42 may be used.
  • the latching tangs 38 are capable of slight pivotal movement relative to the remainder of the latching ring 22 at the free end 40 of the legs 42 and at the connection 46 of the legs to the remainder of the latching ring. Any suitable number of latching tangs may be used.
  • the locking ring 20 has a corresponding number of circumferentially extending bars 48 and circumferentially extending apertures 50, the apertures being axially adjacent the bars.
  • the locking ring 20 is also capable of moving in the axial direction A relative to the latching ring 22.
  • the locking ring 20 preferably has a number of inwardly directed axially extending ribs 52 which make a sliding fit in corresponding grooves 54 in the latching ring 22 to aid the relative axial movement, but to substantially prevent relative rotation between the locking ring and the latching ring.
  • the bars 48 are positioned radially adjacent the latching tangs 38 on the latching ring 22.
  • the apertures 50 are positioned radially adjacent the latching tangs 38 on the latching ring 22.
  • the housing 18 of the second part 16 has a radially outwardly extending rigid lug which is defined by a circumferentially extending rib 56 formed on the outer surface of the housing 18.
  • a number of separate rigid lugs may be formed on the housing 18.
  • the rib 56 engages the latching tangs 38 on the latching ring 22.
  • Both engaging surfaces 58 of the latching tangs 38 and both engaging surfaces 60 of the rib 56 are preferably chamfered to aid latching and delatching as described in more detail below.
  • FIG. 7a shows the arrangement as the housing 18 of the second part 16 is slid into the housing 14 of the first part 12.
  • the rib 56 engages the latching tang 38.
  • the locking ring 20 is biased by the spring 24 to its first position with the bar 48 of the locking ring positioned adjacent the latching tang 38.
  • Further movement of the housing 18 in the direction of the arrow in Figure 7b causes the latching tang 38 to pivot relative to the free end 40 of the leg 42 to allow the rib 56 to pass the latching tang 38.
  • the chamfered engaging surfaces 58,60 aid the passage of the rib 56 passed the latching tang 38.
  • the bar 48 on the locking ring 20 prevents radial outward movement of the latching tang 38 ( Figure 7c) and so any unauthorised attempt to pull the housing 18 out of the housing 14 is substantially prevented by the rib 56 engaging the latching tang 38, and the latching tang engaging the bar 48.
  • the locking ring 20 can be manually push in the axial direction (arrow X in Figure 7d) to its second position against the bias of the spring 24.
  • the aperture 50 in the locking ring is positioned radially adjacent the latching tang 38.
  • Pulling of the housing 18 in the opposed axial direction causes the rib 56 to engage the latching tang 38 to pivot the latching tang radially outwards at the connecting end 46 of the leg 42 into the aperture 50 allowing the housing 18 to be disconnected from the housing 14 of the first part 12.
  • the chamfered engaging surfaces 58,60 aid the passage of the rib 56 passed the latching tang 38.
  • connection of the two parts 12,16 is achieved by a simple push fit.
  • the snap fit of the rib 56 behind the latching tangs 38 provides an audible sound for confirming full and correct mating of the two parts 12,16.
  • the locking ring 20 prevents unauthorised disconnection of the two parts 12,16. Disconnection can be easily achieved simply by manual depression of the locking ring 20.
  • the arrangement of the two-part connector of the present invention therefore overcomes the disadvantages of the prior art connectors in areas where access is difficult.
