It is aimed to enhance efficiency in connecting operation to a shielded cable and prevent the impairment of a shielding function. A terminal fitting (T) includes an inner conductor () including core crimping portions () to be crimped to a core (), a dielectric () made of an insulating material, an outer conductor () including a body portion () configured to surround the dielectric (), a braided wire crimping portion () crimpable to a braided wire and a coupling portion () configured to connect the body portion () and the braided wire crimping portion (), parts of the coupling portion corresponding to the core crimping portions () being vertically opened, and a cover member () configured to close both openings () of the coupling portion ().

Terminal fitting

A terminal assembly includes a wire including a core made of metal and covered with a coating, a terminal including a wire connecting portion connected to an end portion of the wire, a sealing resin sealing the wire connecting portion, and a housing including a through hole with a front opening and a rear opening. The terminal is made of a different kind of metal from the core of the wire. The housing accommodates the terminal in the through hole. The wire connecting portion includes an exposed portion not covered with the sealing resin and unexposed portions covered with the sealing resin. The exposed portion is positioned between the unexposed portions in a front and rear direction, thereby protecting the wire connecting portion from electrolytic corrosion. The exposed portion is obtained after the sealing resin is worn by being rubbed against an inner wall of the through hole.

A connector is provided with a housingfittable into a receptacleof a mating connectorand a retainerto be inserted into the housingsideways. CavitiesA,B for accommodating terminals are arranged side by side in the housing. The retainerincludes a main bodywith side by side engaging portionsA,B for engaging the terminals. Side wallsare provided at the opposite ends in an arrangement direction of the engaging portionsA,B and projecting forward from the main bodyin a connecting direction with the mating connector.

Connector

A flexible wiring member, which is capable of being wound around a wire harness, is provided with joint-side terminals, which are capable of being fitted with wire-side terminals, and the flexible wiring member includes a connection circuit for electrically connecting specified joint-side terminals in the joint-side terminals. Or, a plurality of joint-side terminals are previously held in the insulation housing, and these joint-side terminals are connected with a common flexible wiring member.

Joint member and joint connector for wire harness

A connector has a housing () with cavities () for receiving terminal fittings (). Locks (B) are formed unitarily with the housing and are cantilevered into the cavities (). Deformation spaces () are formed adjacent the lock (B) to accommodate resilient deformation of the locks (B). Each lock (B) has a reinforcing ribs () facing into the deformation space (). Additionally, a wall () of the deformation space () has an escaping portion () for accommodating the reinforcing rib (). The reinforcing ribs () strengthen the locks (B) and escaping portions () prevent enlargement of the housing ().

Connector assembly with terminal retention member

A female terminal fitting () has a main portion () that can be inserted into a cavity. An engaging portion () for engaging a lock () in the cavity is folded back from the front of the main portion (). The fold () is rounded and contacts the lock () when the terminal fitting () is inserted into a cavity. Thus, resistance to insertion is low. The engaging portion () is distanced from an opposed surface () of the main portion () by an embossment (). Thus, a large area of engagement with the lock () exists. A slanted surface () is formed at a corner of a locking surface () closer to the ceiling plate (). Thus, the leading end of the lock () intrudes at the inner side of the slanted surface () to prevent the lock () from escaping.

Female terminal fitting and connector provided therewith

A female housing () is provided with a lock arm () for holding a mating male connector (M) in a connected state. The lock arm () is comprised of an arm () extending along forward and backward directions and an actuator () extending along a width direction. The arm () is resiliently deformed with a support () as a supporting point and has a lock () engageable with the male connector (M). The arm () is displaced in unlocking direction by pressing the actuator (). Two couplings () coupled to the female housing () are provided at opposite sides of the actuator (). The couplings () are inclined up towards a widthwise middle () of the actuator ().

A female housing () made of a synthetic resin is formed with cavities () for accommodating female terminal fittings (), and locks () engageable with the female terminal fittings () to retain them are provided in the cavities (). Each lock () projects from an outer surface () of the female housing () during resilient deformation. A lock arm () for holding a mating male connector (M) in a connected state is mounted on the female housing (). The lock arm () is made of metal and includes a press-in portion () that can be pressed into press-in grooves () of the female housing (). The lock arm () is arranged to face the locks () and can be retracted into deformation spaces () for the locks () during the resilient deformation.

A housing () has cavities () for receiving terminal fittings (), and a lock () is provided in each cavity (). The terminal fitting () temporarily resiliently deforms the lock () when the terminal fitting () is inserted into the cavity (). The lock () then is restored resiliently to engage the terminal fitting () when the terminal fitting () reaches a proper depth. An outer wall () of the terminal fitting () facing the lock () has a locking projection () projecting toward and engageable with the lock (). A recess () is formed in a surface of the lock () that slides in contact with the locking projection () in an inserting process. An arcuate surface () of the locking projection () and a bottom surface () of the recess () have substantially conforming shapes.

Male terminal fittings () are produced by press-cutting a flat base plate () to form original forms () of terminal fittings with base ends () forming plated surfaces () on the outer surfaces of the original forms (). Only one layer of plating is formed on all the surfaces of the base ends () as the plated surface (). The method then includes press-cutting a leading end of the base plate () to form leading ends ().

Method for producing male terminal fittings and terminal fitting

A terminal fitting ( ) has connecting portion ( ) with an engaging portion ( ) to be engaged with a resin lock ( ) of a connector ( ). The engaging portion ( ) projects with a step from an upper wall ( ) to ensure a large engaging area with the resin lock ( ). An outer edge ( A) of the engaging portion ( ) is closer to the resin lock ( ) than an inner edge ( B) thereof. Thus, when the terminal fitting ( ) is pulled back in withdrawing direction, a force acts to move the leading end of the resin lock ( ) from the outer edge ( A) of the engaging portion ( ) toward the inner edge ( B). Therefore, the terminal fitting ( ) is difficult to disengage from the resin lock ( ), and a large engaging force is secured.

Terminal fitting with outwardly projecting engagement portion for engaging a resin lock and a method of forming the terminal fitting

A female terminal fitting ( ) has a rectangular tubular connecting portion ( ) for connection with a male tab ( ). First and second contacts ( C, ) are provided respectively on first and second opposed walls ( ) of the connecting portion ( ). The contacts ( C, ) resiliently contact and hold the male tab ( ). The first contact ( C) is provided at the leading end of a resilient contact piece ( ). An engaging edge ( ) projects from one side of a base ( A) of the resilient contact piece ( ) and is fit into a locking hole ( ) formed in a sidewall ( ) to position the base ( A) of the resilient contact piece ( ) and prevent it from being raised.

A male tab ( ) is formed by bending an electrically conductive plate. The male tab ( ) has a first panel ( A), a second panel ( B) opposed to the first panel ( A), a connecting panel ( C) connecting the first and second panels ( A, B), and a foldable support panel ( D) folded from the second panel ( B). The foldable support panel ( D) is held in close contact with the front and rear panels ( A, B) and prevents the leading ends of the first and second panels ( A, B) from being inclined inward during the pressing.
