In a terminal connection structure, a male terminal and a female terminal are mutually connected by being butted to each other. The male and female terminals are to be connected with respective ends of electric wires. The male terminal includes a male contact portion formed into a curved shape opening on a side opposite to the female terminal. The female terminal includes a female contact portion formed into a curved shape opening on the male terminal side, the curved shape being configured to contact with an outer circumferential surface of the male contact portion. The female contact portion includes contact pieces protruding toward the male contact portion.

Terminal connection structure

A connector terminal comprises: an electrical conductive portion connected with an electrical conductive member; and a connection portion integrally provided with the electrical conductive portion, the connection portion including: a pair of flat plate portions opposed to one another to form an insertion portion into which a corresponding terminal is inserted; a support portion provided in middle portions of the paired flat plate portions, the support portion restricting the paired flat plate portions from moving in directions in which they separate from one another when the corresponding terminal is inserted into the insertion portion, and a plurality of contact portions provided around the support portion in the paired flat plate portions the contact portions elastically contacting with the corresponding terminal to be electrically connected thereto.

Connector terminal

In order to avoid cost for accommodating a shield wire in a housing while bending, and smoothly and readily accommodate within the housing while the shield electric wire is insulated, a conductive housingincluding a rear wallcontinuing to an annular wall, and a tube wallcontinuing to down the rear wall, a method comprising the steps of: passing through a shield electric wirefrom a lower openingof the tube wall of the conductive housing to a front openingof the annular wall while bending the shield electric wire; putting a shield terminalmovably around the shield electric wire from top of the shield electric wire; exposing a core wireand a braidof the shield electric wire by stripping a tip thereof; connecting an L-shaped terminalto the core wire; mounting an L-shaped insulation inner housingoutside the L-shaped terminal; connecting the shield terminal to the braid; and accommodating a vertical partof the inner housing within the conductive housing by pulling in the shield electric wire in an direction contrary to that of the shield electric wire having being passed through, so as to project a horizontal partof the inner housing from the front opening.

Method for manufacturing connector

To electromagnetically-shield an L-shaped terminal in a compact and reliable manner while easily and securely fixing the L-shaped terminal, there is employed an insulating split inner housing having an L-shaped terminal receiving portion including an electric-contact-portion-side receiving portion covering an electric contact portion of the L-shaped terminal connected to a shielded wire and a wire-connection-portion-side receiving portion covering a wire connection portion of the L-shaped terminal, the electric-contact-portion-side receiving portion is covered by a conductive shield shell, the wire-connection-portion-side receiving portion is covered by a conductive housing connected to the shield shell and to a shield portion of the shielded wire, and the L-shaped terminal is insulated by the inner housing from the shield shell and the conductive housing.

Insulating structure for L-shaped terminal

A shield connector includes a housing and a shield terminal. The housing, has a tubular shape so that a shield electric wire is inserted thereinto, and is attached to an objective body so as to communicate with an insert hole of the objective body. The shield terminal, has a tubular shape, is electrically conductive, is attached to an inner peripheral side of the housing, and is electrically conducted to the objective body and the shield layer. A seal member having a tubular shape is provided between an inner periphery of the insert hole and the shield electric wire and between the shield terminal and the shield electric wire, so as to seal a part between the inner periphery of the insert hole and an outer periphery of the shield electric wire and a part between an inner periphery of the shield terminal and the outer periphery of the shield electric wire.

Shield connector

A connecting structure of shield terminals configured to tighten and connect a pair of shield terminals with a single bolt simultaneously in a smaller space, the structure includes: two shield terminals each having a circular portion into which a braided wire of a shield electric wire is inserted and connected, a plate portion extended from the ring-shaped portion along the shield electric wire, and a projecting piece extended perpendicular to the plate portion from a tip of the plate portion and having a bolt-insertion hole at the center thereof, wherein one wall of the projecting piece is positioned on an extension of a center line (m) of the ring-shaped portion, wherein one shield terminal is inverted 180 degree, and wherein the one wall of the projecting piece of the one shield terminal is overlapped with and abuts on the one wall of the projecting piece of the other shield terminal.

Connecting structure of shield terminals

Either displacement of a shielding sleeve itself on an outer cover is restricted or interference of a shielding member on the shielding sleeve with the outer cover as an insulating cover is prevented, so that the damage of the outer cover can be avoided. A shielded connector of the present invention includes a shielding sleeve, a hollow cylindrical housing, and a shielding terminal. The shielding sleevehas an upstanding piecethat stands up in an outer diameter direction to prevent such an event that an end portion of a shielding memberor an end portion of the shielding terminalcomes into contact with the outer cover

Shielded connector

An L-shaped connector, which can waterproof simply and connect an L-shape terminal to an electric shield wire in miniaturized size so as to insulate and electromagnetic shield the L-shaped terminal, includes an L-shaped dividable insulation inner housing receiving an L-shaped terminal joined to the electric shield wire; an electric conductive shield shell covering a terminal receiving portion of the inner housing; an outer housing covering the shield shell; an electric conductive housing receiving a wire lead-out portion of the inner housing, and joining a flange of the shield shell and a flange of the outer housing to a flange of the electric conductive housing by screwing, and connecting a shield portion of the electric shield wire through a shield terminal to the shield shell; and a shield packing waterproofing between the flange of the shield shell and the flange of the electric conductive shell.

L-shaped connector

An object of the present invention is to provide a watertight shield connector able to waterproof successfully without an effect of a parting line, and surely preventing an annular packing or a shield shell from falling out with a plain structure. For attaining the object, there is provided a watertight shield connectorincluding: an insulating connector housinghaving a terminal attaching portionprojected outward from a flange wall, and an annular holedisposed around the terminal attaching portion; a terminalconfigured to be inserted into the terminal attaching portionand having a step portionin a middle thereof; a conductive shield shellhaving a flange plateabutting on the flange wall; an annular packinghaving an annular packing main bodyattached to the annular hole, and a flange-shaped projectiondisposed on an outer periphery of the packing main bodyand abutting on the flange plate; and a spacerconfigured to be engaged with the step portion of the terminal and to abut on an outer end wallof the annular packing
