An object is to provide a technique by which a space in a vehicle in which a wire harness including a plurality of splice circuits is arranged can be reduced and good manufacturability at the time of manufacture can be achieved. A stacked connector is formed by joining a plurality of split connectors to each other. The split connectors each include a split connector housing provided with a plurality of terminal receiving chambers and a plurality of terminal-equipped electric wires that each include a terminal received in the terminal receiving chamber and an electric wire to which the terminal is connected. At least one of the split connector housings is provided with a locking portion having a protruding shape that protrudes outward to be capable of locking the terminal-equipped electric wire received in the split connector housing of a joining counterpart.

Stacked connector and wire harness

A wire with terminal, () includes a barrel () formed in a rear end part of a terminal fitting () such that two crimping pieces () extend from both widthwise side edges of a base plate () and crimped to surround an exposed area () of a core () with extending end parts (E) of the crimping pieces () held close to each other, and a mold () covering the entire exposed area of the core () including a crimped part to the barrel () in a liquid-tight manner. A front end of the core () is disposed behind those of the crimping pieces (). The barrel () is formed with a communicating portion () for causing a crimping space () of the barrel () to be open in an outer peripheral surface of the barrel () on a side before the front end of the core ().

A connector (A) includes a barrel () formed in a terminal fitting () and crimped to surround a front end part of a coated wire (). The barrel () has a base plate () connected to a bottom portion () of a terminal body () and two crimping pieces () extending from both widthwise sides of the base plate (). A molded portion () surrounds the barrel () over an entire periphery and is configured to cover the front end part of the coated wire () in a liquid-tight manner. A housing () is formed with a terminal accommodation chamber () for accommodating the entire terminal fitting (). The base plate () is raised with respect to the bottom portion () of the terminal body ().

Connector housing containing a wire terminal with a molded portion

A connector includes barrels () formed in rear end parts of terminal fittings () and crimped to surround front end parts of coated wires (). First to third molds (A,B,C) each covering the front end part of the coated wire () including a crimped part to the barrel () in a liquid-tight manner. A housing () is formed with terminal accommodation chambers () each for accommodating the entire terminal fitting () and a front end area of the mold (A,B,C), and first to third contacts (A,B,C) each formed on a projection () of the mold (A,B,C) projecting out from the housing () and configured to suppress deformation of the projection () of the mold (A,B,C) by coming into contact with the housing ().

Connector

A wire with terminal includes a wire in which a core is covered with a coating, and a terminalincluding a wire barrelto be crimped to the core exposed from the coating of the wire and an insulation barrelto be crimped to the coating of the wire. The wire is pulled rearwardly from the terminal. RecessesB are provided on a surface of the insulation barrelto be crimped and openings of the recessesB are shaped to become narrower toward a rear side. As the wire is pulled more rearwardly, the coating penetrating into the recessesB moves rearwardly of the recessesB to be compressed and hardened and becomes less likely to come out of the recessesB. Thus, impact strength can be enhanced.

Wire with a crimped terminal

A terminal that is connected to an end of an aluminum electric wire obtained by covering core wires with an insulating cover. The terminal is provided with a pair of insulation barrel pieces (crimping pieces) that extend in directions that intersect the longitudinal direction of the aluminum electric wire, and are crimped to the outer circumferential surface of the insulating cover. The pair of insulation barrel pieces have tip end portions that face and abut against each other in a state in which the pair of insulation barrel pieces are crimped to the insulating cover.

Terminal and terminal-equipped electric wire

An electric wire with terminal includes an electric wire covering an outer periphery of a core wire with an insulating coating and a female terminal. The female terminal includes: a wire barrel having a bottom plate on which the core wire is placed and crimped onto the core wire; a groove portion extending from the bottom plate in a direction in which the core wire extends and whose surface on the side where the core wire is placed is bent into a concave shape. The groove portion has a water blocking wall molded by synthetic resin. The water blocking wall is provided to fill the inside of the groove portion. A region extending from the water blocking wall to the end of the insulating coating is covered with a water blocking coating, and the inner surface of the water blocking coating is in close contact with the water blocking wall.

Electric wire with terminal and connector

It is aimed not to increase contact resistance between a wire and a wire crimping portion even upon being subjected to a thermal cycle. A gold plating layer is formed on a base metal () via a nickel plating layer () in a terminal contact portion () to be held in contact with a mating terminal. A tin plating layer () is formed on the base metal () without via the nickel plating layer () in a wire crimping portion () to be crimped and connected to a core () of an insulated wire ().

Terminal fitting

A terminal () has a terminal main body () with a projection () to be engaged with a retainer (). A wire barrel () to be crimped to a core () of a wire (), an insulation barrel () to be crimped to an insulating coating () and a rubber plug barrel () to be crimped to a rubber plug () are successively arranged behind the main body (). Bottom parts of the wire barrel () and the insulation barrel () are at low positions having substantially the same height. A front end of the wire barrel () is crimped flat to suppress bend-up of the core (). The front end of the crimped wire barrel () is insertable to a position facing a projecting end of the retainer () when the terminal () is inserted to a proper position in a cavity () of a housing ().

Terminal fitting and a connector

Rear engageable surfaces (B) of engageable portions () face communicating portions () and are inclined to produce forces for pushing another housing () forward in a connecting direction with one housing () upon receiving resilient restoring forces of leg portions () when a pair of connectors () reach a properly connected state. A fitting portion () of the second connector () is formed with slanted surfaces () inclined to reduce the width of the fitting portion () toward the back side of the fitting portion (). The slanted surfacesand the first connector () are set to come into contact at a position where a clearance is defined before the first connector () in the connecting direction with the second connector ().

Connector device and locking structure

Each of a plurality of auxiliary connector () includes an auxiliary housing (), a seal () attached to the rear of the auxiliary housing (), and a rear holder () mounted on the rear of the seal () to retain the seal (). Auxiliary connectors () that are adjacent in an arranging direction are united by the rear holders (). The united auxiliary connectors () are inserted into a frame () in the arranging direction through an insertion opening (A) of the frame (), and are retained in the frame () by engaging a lock (B) on the last auxiliary connector (A) and an interlocking portion () of the frame (). The frame () has no partition walls between the auxiliary connectors (). Thus, the connector is narrowed by a total thickness of the partition walls.

Connector and a connector assembly method

A female connector (F) is provided with an outer housing () in the form of a bottomed tube, a spring member () to be accommodated in the outer housing (), and an inner housing () to be accommodated in the outer housing () to sandwich the spring member () between the inner housing () and a back wall () of the outer housing () and adapted to hold female terminal fittings (). The inner housing () is pushed by a male connector (M) to move toward the back wall () and is floating-supported between the back wall () and the male connector (M) via the spring member () to move in connecting directions when the male connector (M) is fitted into the outer housing () to be locked therein. Upon an occurrence of vibration, the inner housing () is capable of moving while following movements of the outer housing ().
