The second connector includes a plurality of second terminal units facing the plurality of first terminal units and a plurality of movable terminal units. The second terminal unit is formed such that a second inner conductor is surrounded by a second outer conductor. The movable terminal unit is swingable with the second terminal unit as a fulcrum. A tip part of the movable terminal unit is connectable to the first terminal unit. The plurality of movable terminal units are coupled to swing integrally by an alignment member.

Connector device

A connector is provided with a connecting member including a contact point portion, a housing for holding the connecting member and a protecting member displaceable with respect to the connecting member to a protection position for protecting the contact point portion and a connection position for bringing the contact point portion into contact with a circuit board. The housing includes a lock portion for holding the protecting member at the protection position.

Board connecting connector

A card edge connector includes: a housing including a board accommodation space and a connection terminal including a resilient contact piece configured to contact a circuit board inserted into the board accommodation space, the connection terminal being mounted into the housing. The connection terminal is movable between a connection position where the resilient contact piece is in contact with a surface of the circuit board and a retraction position where the resilient contact piece is separated from the circuit board. A first interference preventing portion and a second interference preventing portion are formed between a moving path of the resilient contact piece and the board accommodation space. The first interference preventing portion and the second interference preventing portion restrict the interference of the resilient contact piece and an inserting end part of the circuit board inserted into the board accommodation space in a moving process of the connection terminal.

Card edge connector preventing a reduction in connection reliability

It is aimed to reduce connection resistance between a female housing and a male housing without causing the settling of a resilient contact piece of a female terminal fitting. A female connector (F) includes a female housing () configured to accommodate female terminal fittings () and to be connected to a male housing (), and a movable portion () displaceable between a terminal deforming position where resilient contact pieces () are resiliently deformed away from male terminal fittings () and a releasing position where the movable portion is disengaged from the resilient contact pieces (). As the connection of the female housing () and the male housing () proceeds, a retainer-side slide-contact portion () slides in contact with male-side slide-contact portions () and the movable portion () is displaced from the releasing position to the terminal deforming position.

Connector having a movable member

It is aimed to realize space saving. A female connector includes female terminal fittings to be connected to male terminal fittings, a female housing for accommodating the female terminal fittings and a retainer displaceable between a terminal deformation position where the female terminal fittings are deformed and a release position where the retainer is separated from the female terminal fittings. The female terminal fitting includes a resilient contact piece for resiliently contacting the male terminal fitting. The retainer resiliently deforms the resilient contact pieces away from the male terminal fittings at the terminal deformation position.

Female connector and connector

It is aimed to reduce cost. A female connector (F) includes a female housing () to be connected to a male housing (), a lock functioning portion () provided on the female housing () and configured to lock the female housing () and the male housing () in a connected state by being locked to the male housing (), and a releasing member () attachable to and detachable to the female housing (), the releasing member being a component separate from the female housing (). The releasing member () can displace the lock functioning portion () to disengage the lock functioning portion () from the male housing () while being mounted on the female housing ().

It is aimed to prevent the damage and deformation of a terminal fitting. A connector is provided with a housing including a terminal accommodation chamber, and a terminal fitting including a tube portion and a resilient contact piece accommodated in the tube portion, the terminal fitting being inserted into the terminal accommodation chamber.
