  • Patent number: 11728589
    Abstract: A connector 10 includes a first housing 11 and a second housing 12 to be coupled to each other. The first and second housings 11, 12 respectively include a first wall 24 and a second wall 44 partitioning between the first and second housings 11, 12. The first housing 11 includes a first cavity 13, a reference portion 27 constituting a part of the first wall, 24 and a first opening 29 communicating with the first cavity 13. The second housing 12 includes a restricting portion 47 constituting a part of the second wall 44. The restricting portion 47 projects into the first cavity 13 from the first opening 29 beyond the reference portion 27, and a tip thereof in a projecting direction is arranged to face an end part of a wire 30.

  • Patent number: 8641433
    Abstract: A lever (60) is formed with a resiliently deformable lock arm (71) projecting substantially along a rotating direction of the lever (60). A housing (20) is formed with a base piece (27) standing in a direction crossing a connecting direction to a mating connector (90). An engaging portion (35) for holding the housing (20) and the mating connector (90) in the properly connected state by being resiliently engaged with a leading end part of the lock arm (71) is formed on a leading end part of the base piece (27). A recess (33) into which a finger (50) is insertable to disengage the engaging portion (35) and the lock arm (71) is formed in a base end part of the base piece (27).

  • Patent number: 8602819
    Abstract: A connector housing (20) includes cavities (30) into which terminal fittings (90) are to be inserted, a front wall (40) capable of stopping the terminal fittings (90) inserted into the cavities (30) at front end positions, and resiliently deformable locking lances (33) cantilever from inner surfaces of the cavities (30). Projections (50) project from a side where the front wall (40) is located toward a side where the locking lances (33) are located. The projections (50) are arranged to contact the locking lances (33) from an opposite side in a resilient deforming direction of the locking lances (33) when the locking lances (33) are about to be deformed excessively.

  • Patent number: 8403693
    Abstract: A connector housing (10) is formed with a seal tower (18) projecting backward from the rear surface of the connector housing and adapted to accommodate seals (20). A peripheral wall (21) surrounds the seal tower (18) and projects back from the rear surface of the connector housing (10). A rearwardly open groove-shaped annular recess (22) is formed between the seal tower (18) and the peripheral wall (21) and has a bottom surface (23) that defines the rear surface of the connector housing. The bottom surface (23) of the recess (22) is continuous over the entire circumference, and the peripheral wall (21) is formed with water drains (24) that cause the inside of the recess and an outer peripheral side of the peripheral wall to communicate.
