  • Patent number: 11329423
    Abstract: An electric connector includes a tubular conductive shell, covers provided outside the shell to cover at least part of the shell, and a movable cover coupled to the cover through a rotary shaft. The cover has locking pieces on a cable side. The movable cover has locking pieces to be engaged with the locking pieces. At least one of the locking piece or the locking piece includes multiple locking pieces arranged along a circumferential direction of a circle about the rotary shaft. The locking pieces and the locking pieces form a ratchet mechanism, and have such a structure that the locking pieces and the locking pieces are movable in an approaching direction and movement in a direction in which the locking pieces and the locking pieces are separated from each other is restricted.

  • Publication number: 20210296816
    Abstract: Provided is a technique of reliably easily making connection even in a case where the thickness of a cable is changed in an electric connector for a shield-equipped multicore cable. The electric connector includes a tubular conductive shell 30, covers 40 and 50 provided outside the shell 30 to cover at least part of the shell 30, and a movable cover 60 coupled to the cover 50 through a rotary shaft 63. The cover 40 has locking pieces 41 on a cable side. The movable cover 60 has locking pieces 61 to be engaged with the locking pieces 41. At least one of the locking piece 41 or the locking piece 61 includes multiple locking pieces arranged along a circumferential direction of a circle about the rotary shaft 63.

  • Patent number: 10971862
    Abstract: When a swaging portion (71) of one shell (60) is swaged to a cable (5), even in a case where a main body (42) of the other shell (40) receives tensile force through a sandwiching portion (43) sandwiched between the swaging portion (71) and the cable (5), the risk of pulling the main body (42) of the other shell itself is reduced, and deformation and damage of the other shell (40) are prevented. A cable connector includes a housing (20) configured to hold one end of a cable (5) and a first shell (60) and a second shell (40) including main bodies covering at least a portion of the housing (20). The first shell (60) has a swaging portion (71) to be swaged to the cable (50). The second shell (40) has a sandwiching portion (43) to be swaged together with the cable by the swaging portion (71) with the sandwiching portion being sandwiched between the swaging portion (71) and the cable.

  • Patent number: 9231345
    Abstract: A connector is to be connected to a mating connector. The connector includes a base portion for accommodating a plug and a cable connected to the plug; a connecting member disposed on the base portion to be rotatable relative to the mating connector for connecting the connector to the mating connector; a tightening member disposed on the base portion to be movable relative to the connecting member for tightening the cable; and a rotation preventing member disposed on the base portion to be movable relative to the connecting member for engaging with the connecting member so that the rotation preventing member prevents the connecting member from rotating relative to the mating connector.
