  • Patent number: 11239583
    Abstract: A connector includes a terminal clasp, a flexible flat conductive component, a housing in which an electrical connection part of the terminal clasp protrudes out of an opening of a storage room, and a cover that covers the electrical connection part from outside together with at least part of the housing. The flexible flat conductive component includes an electrical connection region in which the electrical connection part is connected with a conductor, a peripheral region enclosing the electrical connection region, an extension region extending out of the housing and the cover connected with each other, and at least two fitting holes provided on the extension region side in the peripheral region.

  • Patent number: 11158977
    Abstract: A connector includes a housing in which a terminal fitting is stored, and a cover. A guiding structure configured to guide the housing and the cover in a connection direction, and a holding structure configured to hold the housing and the cover at a connection completed position are provided between the housing and the cover. The guiding structure includes a wedge guiding protrusion provided to the cover, and a wedge guiding groove provided to the housing. The wedge guiding protrusion and the wedge guiding groove are formed to have a gap between a protrusion-side wall surface and a groove-side wall surface disposed opposite to each other in each of two pairs. The holding structure includes a press-fit protrusion being configured to hold the wedge guiding protrusion and the wedge guiding groove in a press-fitted state when the housing and the cover are at the connection completed position.

  • Patent number: 11121497
    Abstract: A connector includes: a housing; and a cover. The housing includes a lock body that is lockable to a counterpart lock body so that fitting connection with the counterpart housing is not canceled, and a lock cancellation arm that deforms with application of lock cancellation force to a point-of-effort part and cancels a state in which the lock body is lockable to the counterpart lock body. The cover includes a second wall that covers the housing up to the position of the point-of-effort part in the fitting connection direction, an exposure part formed at the wall to expose the point-of-effort part, and a lock cancellation operation body that includes an operation part capable of receiving a press movement operation, blocks the exposure part to an extent that deformation along with the press movement operation is possible, and applies the lock cancellation force to the point-of-effort part through the deformation.

  • Patent number: 10191225
    Abstract: A cover part of an optical fiber is sandwiched and pressed between a pressure welding blade and a bottom surface part. As a result of this, in a case where an external force which pulls out the optical fiber from a housing, movement of the optical fiber is suppressed by a pressing force, which makes it difficult for a ferrule to go away from a mating optical fiber. Thus, efficiency in communication with the mating optical connector can be improved.

  • Patent number: 9825397
    Abstract: A grommet-equipped connector includes a connector and a grommet. The connector includes a panel engagement portion configured to be engaged with an attachment hole of a panel and an annular flange configured to face an edge portion of the attachment hole. The grommet includes a panel contact portion configured to be fitted so as to cover the flange and intimately contact the edge portion. A flange fitting groove in which the flange is inserted over an entire perimeter is formed inside the panel contact portion. The flange has a flange protrusion portion protruding outward and guided by the flange fitting groove.
