A lever-type connector has a female housing (F) with a tubular fitting () that includes a lever accommodating portion () for accommodating a lever () and an inner regulating wall () on a side opposite to the lever accommodating portion (). A male housing (M) has a receptacle () with an outer regulating wall () facing the inner regulating wall (), and has a supporting wall () facing the lever accommodating portion (). A cam follower () and a regulating protrusion () are formed on an outer surface of the supporting wall () and can contact the lever () by being inserted into an opening () of the lever accommodating portion (). Contact of the regulating protrusion () and the lever () regulates inclination of the housings (F, M) in the process of rotating the lever ().

Lever-type connector with regulating protrusion on male housing that engages lever on female housing to achieve connection without inclination between male and female housings

A lever-type connector has tubular fitting () with an outer regulating wall () on a side opposite to a lever accommodating portion () across a terminal accommodating portion (). A receptacle () includes an inner regulating wall () arranged along the outer regulating wall () and a facing wall () arranged along the lever accommodating portion () and facing the inner regulating wall (). Regulating protrusions () are formed on an inner surface of the inner regulating wall (). Posture inclination between a female housing (F) and a male housing (M) is regulated by contact of a tip outer edge (E) of the inner regulating wall () and an inner surface of the outer regulating wall () and by the contact of a tip outer edge (E) of the terminal accommodating portion () and the regulating protrusions ().

Lever-type connector

A wire harness is constructed by bundling a plurality of electric wires in which conductors are surrounded with insulating coatings respectively. The electric wires are constructed of aluminum electric wires in which the conductors consist of aluminum or aluminum alloy and copper electric wires in which the conductors consist of copper or copper alloy. A plurality of the aluminum electric wires is disposed so as to surround the copper electric wires having a lower shape retention property than the aluminum electric wires. The bundles electric wires include bent portions formed by bending or curving the bundled electric wires respectively.

Wire harness

A terminal fitting () is provided with a box-shaped main portion () capable of receiving a tab () of a mating terminal fitting () and a resiliently deformable resilient contact piece () arranged in the main portion () to be connected to the tab () inserted into the main portion (). The resilient contact piece () includes a supporting portion () for resilient deformation in the main portion (). The main portion () includes a base portion () facing the resilient contact piece () in a resilient deforming direction of the resilient contact piece (). The base portion () includes a recess () formed within the thickness range thereof the base portion (), and the supporting portion () is in contact with the bottom surface of the recess ().

Terminal fitting

A terminal fitting () has a rectangular tube () for receiving a mating male tab (). A resilient contact () is formed in the rectangular tube () and can resiliently contact the male tab (). An excessive deformation preventing portion () is formed in the rectangular tube () for preventing deformation of the resilient contact () beyond a resiliency limit by contacting the resilient contact () being resiliently deformed. The terminal fitting () also has an extending portion () projecting out from an end edge of the rectangular tube portion () in a developed state before being bent and arranged at an outer side of the resilient contact () after being bent. The excessive deformation preventing portion () is formed by bending a part of the extending portion () into the interior of the rectangular tube ().

Front shake preventing ribs () are provided at positions spread over the entire inner periphery of a front end of an inner housing () and contact a receptacle () of a male housing () to prevent shaking between an inner housing () and a receptacle (). A wall () faces an opening edge portion of the receptacle () at a rear end of the inner housing () with respect to the connecting direction with the male connector (). The receptacle () is formed with an annular rib () projecting in a connecting direction the connectors () at a position to surround the inner housing () over the entire periphery. The wall () has an annular groove () that engages the annular rib () to prevent shaking between the connectors ().

Connector device

A watertight connector has a rubber member () mounted on an inner housing (), and this rubber member () includes a sealing portion () substantially in the form of a tube fittable on the outer circumferential surface of the inner housing () before a flange (), legs () integral to the sealing portion () and shaped to be insertable backward through pass-through openings (), and backlash preventing portions () integral to the legs (), shaped to be engageable with the peripheral edges of the pass-through openings () from behind and arranged between the flange () and a facing wall ().

Fluidtight connector and connector assembly

When a male housing () and a female housing () are connected, projections () formed in the male housing () are pressed into fitting holes () of a seal () mounted on the front surface of a terminal accommodating portion (A) after passing through projecting-portion insertion holes () formed in a cover wall () of the female housing (). Shaking is prevented by shake preventing portions () projecting from the outer circumferential surfaces of the projections (), thereby suppressing relative vibration of the housings () and preventing fine sliding abrasion of male tabs () and female terminal fittings ().

Fluidtight connector

A holding cap (RC) is mounted on a terminal holding portion () of a female housing () from the front, and a tubular cover () is so formed outward of the terminal holding portion () to surround the holding cap (RC). First shake preventing portions (RC) project radially out from the outer surface of the front end of the holding cap (RC) and second shake preventing portions () project in at the rear end of the inner surface of the cover (). When male and female connectors () are connected with each other, the first and second shake preventing portions (RC) both contact a receptacle () of a male housing () to reduce the shaking between both housings () in transverse directions.

Connector, a mating connector and a connector device

A connector has a housing () with cavities () for receiving terminals (). A lock () projects is provided in each cavity () and has a forwardly tapered locking surface () that is sloped to project more forward at the base than at the top. The connector also has a retainer () with a restricting plate () to prevent displacement of the locks () toward deformation spaces (). Push-up protrusions () of the restricting plate () slip under the lower surfaces of the locks () as the retainer () is pushed towards a full locking position and push the locks () up towards cavities (). A cam action of the sloped locking surfaces () pushes the female terminals () forward and against front walls ().

Connector and a method of assembling such connector

A connector () has terminal fittings () each of which has a connecting portion () formed with slits () for receiving a busbar (B). The connector () also has a housing () with terminal accommodating chambers () arranged side-by-side in an arranging direction (AD) for receiving the terminal fittings (). The arranging direction (AD) is normal to the slits (). The terminal accommodating chambers () are displaced from the adjacent ones in a direction normal to the arranging direction (AD). As a result, the height of partition walls () between the adjacent terminal accommodating chambers () is shorter than the height of the terminal fitting (), thereby preventing the slits () from being fit to the partition wall () at the time of inserting the terminal fitting
