  • Publication number: 20170222363
    Abstract: A connector (F) includes an inner housing (11) configured to accommodate terminal fittings (72). An outer housing (37) is separate from the inner housing (11) and is configured to surround the inner housing (11). A lock arm (17) is formed on an outer surface of the inner housing (11) and is configured to lock the inner housing (11) and a mating housing (80) in a connected state by being locked to the mating housing (80). Protecting portions (45, 46) are formed on the outer housing (37) and are arranged near a lock releasing portion (22) of the lock arm (17).

  • Publication number: 20170214180
    Abstract: A moving plate (30) includes two resilient locking pieces (34) and can be resiliently curved and deformed to incline a projecting direction of the resilient locking pieces (34), and a female housing (50) pulls the moving plate 30 back to an initial position by locking locks (55) to the resilient locking pieces (34). With the moving plate (30) held at the initial position by initial position holding projections (18), the locks (55) of the female housing (50) are displaced to locked positions to the resilient locking pieces (34) by resiliently deforming the resilient locking pieces (34). The initial position holding projections (18) are spaced apart in the same direction as a separating direction of the resilient locking pieces (34) and arranged at positions different from the pair of resilient locking pieces (34) in the separating direction of the pair of resilient locking pieces (34).

  • Publication number: 20170214174
    Abstract: A moving plate (30) includes two resilient locking pieces (34) and can be resiliently curved and deformed to incline a projecting direction of the resilient locking pieces (34). With the moving plate (30) held at an initial position by retaining projections (21), locks (55) of a female housing (50) are displaced from positions where the locks (55) are locked to the resilient locking pieces (34) to positions where the locks (55) are not locked to the resilient locking pieces (34) by resiliently deforming the resilient locking pieces (34). The retaining projections (21) are spaced apart in the same direction as a separating direction of the resilient locking pieces (34) and are at positions different from the resilient locking pieces (34) in the separating direction of the resilient locking pieces (34).

  • Publication number: 20170214179
    Abstract: A male housing of a connector assembly has moving plate (30) with a pair of resilient locking pieces (34) that can be curved resiliently and deformed to incline a projecting direction of the resilient locking pieces (34). A female housing (50) causes the moving plate (30) to interfere with initial position holding projections (18) and pulls the moving plate (30) back to an initial position by locking with locking portions (55) to the resilient locking pieces (34). The initial position holding projections (18) are paired and spaced apart in the same direction as a separating direction of the resilient locking pieces (34) and are arranged at positions different from the resilient locking pieces (34) in the separating direction of the resilient locking pieces (34).

  • Patent number: 8777648
    Abstract: A connector includes a one-piece rubber plug (30) arranged to cover a rear surface (10R) of an inner housing (10) and has seal holes (31) aligned with cavities 12. An outer housing (20) has a tubular portion (21) surrounding the inner housing (10) and a rear wall (24) covering a rear surface (30R) of the one-piece rubber plug (30). The rear wall (24) has insertion holes (25) aligned with the seal holes (31). Locking holes (26A, 26B) are open on a rear surface (24R) of the rear wall (24), and locks (17A, 17B) on the inner housing (10) engage with the locking holes (26A, 26B) to lock the housings (10, 20) in an assembled state.

  • Patent number: 8530456
    Abstract: The present invention relates to macrocyclic small molecule inhibitors of the Sonic Hedgehog signaling pathway, syntheses thereof, and intermediates thereto. Such small molecule modulators of the Sonic Hedgehog signaling pathway are useful in the treatment of proliferative diseases (e.g., basal cell carcinoma, Gorlin syndrome, medulloblastoma, or pancreatic cancer), pulmonary diseases (e.g., interstitial pnuemonitis or interstitial pulmonary fibrosis), and developmental disorders (e.g., phocomelia or cyclopia). Novel non-natural macrocycles are provided that inhibit Sonic Hedgehog induced-protein transcription.
