Definitions

  • the present invention relates to a seal ring and a sealed electrical connector using same.
  • a seal ring for sealing the male and female housings is generally mounted on the outer surface of the male housing, and the resultant structure is inserted into the female housing.
  • the seal ring since the seal ring is exposed on the outer surface of the male housing, the seal ring may be susceptible to external influences. For example, the seal ring may be damaged during assembly, thus impairing the waterproof properties.
  • a waterproof connector having a cylindrical outer wall for protecting a seal ring on a male housing Japanese Patent Application No. 1-51031.
  • the male housing has a relatively high profile, and the connector is bulky, resulting in inconvenience.
  • EP-A-0132099 discloses a connector seal ring comprising an elastomeric ring body, at least one projection formed on an outer peripheral surface of said ring body, and at least one projection formed on an inner peripheral surface of said ring body.
  • EP-A-0335721 discloses a rubber gasket for a waterproof electric connector, the gasket having recesses in its surface which cooperate with projections on the connector.
  • a connector seal ring comprising an elastomeric ring body, at least one projection formed on an outer peripheral surface of said ring body, at least one projection formed on an inner peripheral surface of said ring body, and a locking groove extending into said ring and between said projections, said locking groove having a groove communicating therewith and formed in a direction generally perpendicular to the direction of depth of said locking groove.
  • the invention further provides a sealed connector comprising a male housing, a female housing having a cavity receiving said male housing, and a seal ring according to the invention, wherein said seal ring is disposed in said cavity and interposed between an outer wall surface of said male housing and an inner wall surface of said female housing when said male and female housings are joined with each other.
  • Figure 1 is a plan view showing an arrangement of a seal ring according to the present invention.
  • Figure 2 is a sectional view of the seal ring of Figure 1, as seen along viewing lines II-II.
  • Figure 3 is a sectional view showing an arrangement of an electrical connector according to the present invention, using the seal ring of Figure 1.
  • a seal ring according to the present invention is shown in Figures 1 and 2.
  • the seal ring comprises a rubber ring body 1, projections, such as ribs 2, formed on the outer peripheral surface of the ring body, and projections, such as ribs 3, formed on the inner peripheral surface of the ring body.
  • a locking groove 4 is formed into the ring body and between the projections 2 and 3. In the illustrated embodiment, a total of six locking grooves are formed along the circumference of the seal ring.
  • locking grooves 4 are to be respectively engaged with latch projections 12 (see Figure 3) formed in a cavity of a female housing 11 for receiving a male housing 10, the locking grooves 4 are formed at positions respectively corresponding to the latch projections, as will be indicated hereinbelow.
  • the locking groove 4 has a groove 4A extending in a direction perpendicular to the direction of depth of the locking groove 4.
  • the groove 4A corresponds to a projection 12A (see Figure 3) extending from the corresponding latch projection 12 formed in the cavity of the female housing 11.
  • the projections 2 and 3 are formed at substantially corresponding, opposite positions.
  • Figure 3 shows a sealed connector including the seal ring described above.
  • the connector comprises a male housing 10, a female housing 11 having a cavity for receiving the male housing 10, and the seal ring.
  • the grooves 4 on the seal ring are engaged with the latch projections 12 extending from the bottom surface of the cavity of the female housing 11.
  • the seal ring is interposed between an outer wall surface of the male housing and an inner wall surface of the female housing to seal the male and female housings when the male and female housings are joined with each other.
  • reference numeral 13 denotes wires each having a distal end terminating at a corresponding receptacle contact 14.
  • a ferrule 14A (crown-shaped cap) is mounted on the distal end of the receptacle contact.
  • a pin contact 15 is received into the corresponding receptacle contact through the corresponding ferrule.
  • Each pin contact extends through the bottom portion of the cavity of the female housing 11.
  • the pin contact extending through the housing is inserted into and fixed on a printed circuit board 20 through an alignment plate 16.
  • Reference numeral 17 denotes a bushing having a plurality of holes for receiving the wires 13.
  • the bushing 17 serves to seal the wires 13 and the male housing 10.
  • Reference numeral 18 denotes a packing rubber member and reference numeral 19, a unit case.
  • the seal ring according to the present invention has the locking grooves which are respectively engaged with the latch projections formed on the bottom of the cavity of the female housing, the seal ring is not inadvertently folded or the like when the male housing is fitted in the cavity of the female housing. Therefore, the sealing effect is not impaired.
  • seal ring Since the seal ring is fixed in the cavity of the female housing, the seal ring tends not to be adversely affected externally.
  • a special structure for protecting the seal ring e.g., a cylindrical outer wall for protecting the seal ring in a known connector
  • each locking groove of the seal ring of the present device has a groove extending in a direction perpendicular to the direction of depth of the locking groove, the seal ring is not easily removed from the latch projections.
