It is aimed to satisfactorily correct the position of a lock arm. A connector () is provided with a first housing (), female terminal fittings () to be inserted into the first housing () from behind, a second housing () to be connected to the first housing (), a lock arm () provided at the first housing () and displaceable to a lock position where the first and second housings () are locked in a connected state by the lock arm locking the second housing () and a lock releasing position where separation of the first and second housings () is enabled by releasing the locking, and a correcting portion () arranged to face a surface on an unlocking direction side of the lock arm () in the connected state.

Connector with correcting portion for lock arm

It is aimed to achieve a height reduction. A connector (F) is provided with a female terminal fitting () and a housing (). The female terminal fitting () includes a tab inserting portion (), into which a tab () of a male terminal fitting () is inserted, and a first resilient contact piece () exposed on an outer surface of the tab inserting portion () and configured to resiliently contact the tab (). The housing () includes a terminal accommodation chamber () for accommodating the tab inserting portion (). A deflection allowance space () for allowing a resilient displacement of the resilient contact piece () is formed within a thickness range of an upper wall portion () defining the terminal accommodation chamber (), out of the housing ().

Connector

It is aimed to provide a connector having a function of protecting a male terminal and capable of coping with size reduction. A connector includes a guide, inside which a female housing is arranged, a cavity located behind the guide and communicating with inside of the guide, a holding member arranged movably in a front-rear direction with respect to the guide, and a male terminal arranged inside the cavity and including a tab projecting forward. The male terminal is provided to move integrally with the holding member.

It is aimed to prevent a reduction in connection reliability. A terminal fitting is to be mounted into a housing having a board accommodation space and is provided with a connection terminal including a resilient contact piece to be brought into contact with a circuit board inserted into the board accommodation space and a protection terminal separate from the connection terminal and attached to the connection terminal. The connection terminal is movable with respect to the protection terminal between a protection position where the resilient contact piece is accommodated in the protection terminal and a connection position where the resilient contact piece is exposed to outside of the protection terminal to be contactable with the circuit board.

Terminal fitting

A circuit board () is arranged in a receptacle (). A housing () having an accommodation space () is fit into the receptacle (). A protecting member () is arranged movably to an initial position and a connection position in the housing (). A terminal fitting () includes a contact point portion () facing the accommodation space (). The protecting member () includes a body portion () to be located on an opening side of the accommodation space () at the initial position and retracted from the opening side of the accommodation space () at the connection position, and a hooked portion () connected to an end part of the body (). The receptacle () includes a hooking portion () on an inner surface for moving the protecting member () from the connection position to the initial position by hooking the hooked portion ().

Card edge connector

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

A lever-type connector includes a housing configured to rotate about a first shaft, a second lever configured to rotate about a second shaft and a cam groove linked with rotation of the second lever. The first lever includes a guide portion extending from an operating portion toward the first shaft, and the second lever includes a coupling portion coupled to the first lever relatively displaceably along the guide portion. The both levers are linked and rotated between an initial position where connection of the housing and a mating housing is started and a connection position where the connection of the housing and the mating housing is completed. When a virtual line passing through the second shaft and the coupling portion with the second lever located at the initial position is set, the first shaft is located closer to the connection position than the virtual line.
