Definitions

  • This invention relates to an electrical connector according to the preamble of claim 1.
  • This invention provides an electrical connector having improved means for dampening vibration of the electrical connector.
  • the electrical connector typically comprised a receptacle connector which was mounted to the firewall and which had a plurality of locking grooves about its periphery.
  • the electrical connector also comprised a mating connector having a locking ring which was rotatably mounted thereon.
  • the mating connector had a plurality of locking lugs which would cooperate with the locking grooves to lock the mating connector to the receptacle connector.
  • a compressible seal was positioned between the locking ring and the firewall.
  • the invention provides an electrical connector as defined in claim 1. Preferred embodiments are defined in the dependent claims.
  • this invention comprises an electrical connector for coupling to a complementary connector which is mounted on a housing, said electrical connector comprising a connector portion for operatively mating with said complementary connector; and dampening means associated with said connector portion for operatively engaging said housing when said electrical connector is mounted to said complementary connector in order to dampen vibration of said electrical connector so that the electrical connection between said complementary connector and said electrical connector is not interrupted, said dampening means being incompressible and resilient.
  • This invention provides an electrical connector having improved means for dampening vibration so that any electrical connection between the electrical connector and its complementary mating connector will not be interrupted.
  • An embodiment of this invention provides an electrical connector having a locking ring comprising a plurality of resilient fingers which are integrally formed as part of the locking ring, thereby eliminating the need for a compressible seal.
  • Another embodiment of this invention provides an electrical connector having improved dampening means comprising a plurality of resilient fingers which cooperate with and engage a housing wall to ensure that the electrical connection between the electrical connector and a complementary mating connector will not be interrupted.
  • the electrical connector 10 comprises a stationary connector or connector portion 12 having a plurality of electrical terminals 14 therein.
  • the connector portion 12 operatively mates with a complementary connector 16 (Fig. 6) which may be mounted to a firewall, bulkhead or similar housing 17, as best shown in Fig. 6.
  • complementary connector 16 After complementary connector 16 is mounted to housing 17, electrical connector 10 may be mounted and dismounted from complementary connector 16 in the manner described later herein.
  • the connector portion 12 comprises a resilient latch 18 (Figs. 2 and 3) which cooperates with an end 12b to define a locking space 20. The function of the locking space 20 is described below.
  • Electrical connector 10 also comprises a cylindrical locking ring 22 which is rotatably mounted about the connector portion 12, as best illustrated in Fig. 2.
  • the locking ring 22 comprises a locking rim 24 (Figs. 2, 4 and 5).
  • connector portion 12 is moved in the direction of arrow A in Fig. 5 into locking ring 22 until locking rim 24 becomes positioned in locking space 20.
  • the resilient latch 18 on connector portion 12 and locking rim 24 cooperate to lock the locking ring 22 onto connector portion 12 while permitting the locking ring 22 to rotate freely on connector portion 12.
  • connector portion 12 and locking ring 22 are generally cylindrical and made of plastic.
  • locking ring 22 comprises a plurality of locking lugs 26.
  • the locking lugs 26 cooperate with a plurality of locking grooves 28 (Fig. 6) on the complementary connector 16 to permit the electrical connector 10 to be coupled to complementary connector 16.
  • the connector portion 12 and complementary connector 16 may comprise detents (not shown) for locking the complementary connector 16 and connector portion 12 together and for retaining the locking lugs 26 in a locked position.
  • locking lugs 26 are located on an inner surface 25 of locking ring 22. The locking lugs 26 are received in the locking grooves 28, such that when the locking ring 22 is rotated in a counterclockwise direction (as viewed in Fig.
  • the electrical connector 10 also comprises dampening means associated with connector portion 12 for operatively engaging housing 17 (Fig. 6) when electrical connector 10 is mounted to complementary connector 16.
  • dampening means is to dampen vibration of the electrical connector 10, thereby facilitating the maintenance of an electrical connection between the connector portion 12 of complementary connector 16 and electrical connector 10.
  • dampening means is incompressible and resilient.
  • dampening means comprises a plurality of axially aligned grooves or slots 30 which define a plurality of resilient fingers 32 on an end 22b of locking ring 22.
  • Each of the plurality of resilient fingers 32 is generally L-shaped in cross-section and has an engaging end 32a (Fig. 5) which engages housing 17 when electrical connector 10 is coupled to complementary connector 16.
  • the plurality of resilient fingers 32 define a circumference and are angularly spaced an equidistant apart along the circumference.
  • the diameter of the circle defined by the engaging ends 32a of the plurality of resilient fingers 32 is approximately 2.375 inches, and the circumference is approximately 7.50 inches.
  • the plurality of resilient fingers 32 may be integrally formed on the engaging end of locking ring 22, thereby providing a locking ring 22 having a single one-piece construction. It is to be noted that each engaging end 32a is beveled to facilitate the movement of the plurality of resilient fingers 32 in a radial direction away from connector portion 12, as described below. The assembly and operation of electrical connector 10 will now be described.
  • the electrical connector 10 is mounted to complementary connector 16 (Fig. 6).
  • the connector portion 12 is operatively aligned with end 16a of complementary connector 16, and the locking lugs 26 are then positioned in locking grooves 28 on complementary connector 16.
  • the locking ring 22 is then rotated in a counterclockwise direction (as viewed in Fig. 1) so that the connector portion 12 is drawn into operative engagement with complementary connector 16.
  • the locking ring 22 is rotated until the plurality of resilient fingers 32 engage the housing 17 and connector portion 12 mates with complementary connector 16. It is to be noted that, as locking ring 22 is tightened, each of the plurality of resilient fingers 32 deflects or resiles radially away from the connector portion 12.
  • the plurality of resilient fingers 32 absorb and dampen shock and vibration of electrical connector 10, so that the electrical connection between electrical connector 10 and complementary connector 16 remains uninterrupted.
  • locking ring 22 is rotated in a clockwise direction (as viewed in Fig. 1) until the locking lugs 26 exit locking grooves 28 on complementary connector 16. It is to be noted that each of the plurality of resilient fingers 32 resile back to their original home position shown in Figs. 1, 2, 4 and 5 when the locking ring 22 is in its unlocked position. If desired, the electrical connector 10 can be remounted on complementary connector 16 in the manner described above.
  • this electrical connector 10 has dampening means comprising a plurality of resilient fingers 32 which absorb shock and vibration and which eliminate the need for a compression type seal or similar device.
