A method for manufacturing a female terminal () with a tubular portion () formed by bending a metal plate into a tubular shape and resilient contact pieces () extending from the tubular portion () in an axial direction of the tubular portion (), folded inwardly of the tubular portion () and configured to resiliently contact a mating terminal inside the tubular portion () includes a joining step of joining metal members thinner than the metal plate to the metal plate, and a forming step of bending the metal members joined to the metal plate and forming the metal members as the resilient contact pieces.

Method for manufacturing female terminal and female terminal

A device connector () is mounted into a mounting hole (C) on a case (C) of a device in a vehicle, and includes terminals () connected to wires (W). A synthetic resin housing () includes a wire introducing portion () and a fitting portion (). The wire introducing portion () receives the wires (W) and the terminals () while the fitting portion () fits into the mounting hole (C). A metal shield shell () accommodates the wire introducing portion () and includes a lower shell () for covering the entire outer circumferential surface of the wire introducing portion (). A seal ring () fits on an outer surface of the wire introducing portion () and seals between the lower shell () and the wire introducing portion (). Water drainage holes () vertically penetrate a stepped portion () of the lower shell () above the seal ring ().

Device connector

A female terminal () includes a tubular portion () into which a male terminal () is to be inserted, a plurality of first resilient pieces () projecting inwardly of the tubular portion () from a bottom wall () of the tubular portion () and arranged side by side in a direction intersecting with an inserting direction of the male terminal () into the tubular portion (), and a plurality of contact portions () arranged at positions of the tubular portion () respectively corresponding to the plurality of first resilient pieces () and configured to sandwich the male terminal () between the plurality of resilient pieces () and the contact portions. Since this enables each first resilient piece () to apply a proper contact pressure to the male terminal (), the male terminal () is pressed against the second contact portions () at a proper contact pressure.

Female terminal having opposed first and second pluralities of resilient pieces, with each resilient piece having a free end and a contact portion near the free end

A connector () to be mounted on end portions of wires () includes first terminals () connected to the end portions of the wires (), second terminals () electrically connected to the first terminals () via flexible conductive members () and connected to terminals of a mating connector (CN), and a housing () for accommodating the first terminals () and the second terminals ().

Connector with flexible conductive member to isolate terminal from vibrations in a wire

A socket terminal () to be fitted and connected to a mating pin terminal () includes a tubular portion () to be fitted to the pin terminal (). The tubular portion () includes a base portion () provided on a side opposite to a fitting starting end to the pin terminal () and a plurality of terminal pieces () extending in an axial direction of the tubular portion () from the base portion () toward the pin terminal (), spaced apart in a circumferential direction of the tubular portion () and capable of resiliently coming into contact with the outer peripheral surface of the pin terminal () fitted in the tubular portion (). The base portion () includes a plurality of terminal pieces () projecting toward the pin terminal () radially of the tubular portion () and configured to hold the outer peripheral surface of the pin terminal ().

Socket terminal

A wiring harness () includes a housing () for holding protected parts each including a connected part of an insulated wire () and a terminal fitting () in a plurality of terminal-provided wires () at intervals inside. The housing () has a double structure including an inner wire protecting member () and an outer wire protecting member (). The inner wire protecting member () holds the protected parts of the plurality of terminal-provided wires (), each in a pivotable state, at intervals. The outer wire protecting member () is formed by insert molding a thermoplastic material with the inner wire protecting member () holding the plurality of terminal-provided wires () as an insert part.

Wiring harness

In a connector () with a first housing () made of resin and including a first terminal portion (A) connected to a first device and a second housing () made of resin and including a second terminal portion (B) connected to a second device, the first and second housings () are coupled and united by a coupling portion () made of rubber and formed by insert molding or two-color molding. A method for manufacturing the connector () of the present invention includes a uniting step of coupling and uniting the first and second housings () by the coupling portion () made of rubber by insert molding or two-color molding.

Connector and method for manufacturing same

A connector includes a connector housing having a cavity, a male terminal having a protruded portion, a sealing ring receiving recess included in the connector housing, a sealing ring arranged in the sealing ring receiving recess, and a retainer mounted in the connector housing and pressing the sealing ring from a front side of the protruded portion of the male terminal. The male terminal is housed in the cavity in a way that the protruded portion protrudes from the connector housing. The sealing ring receiving recess is located at a position corresponding to a base section of the male terminal that is on a side from which the protruded portion protrudes. The male terminal passes through the sealing ring such that it seals a space between the male terminal and an inner surface of the sealing ring receiving recess. The retainer includes an engagement portion engaged with the male terminal.
