Lock structure of connector

A board-mount electrical connector capable of maintaining favorable solderability of a connecting section of a terminal for a long term and preventing occurrence of a whisker in a bent section of the terminal is provided. The electrical connector includes a plurality of terminals each having at one end a contact section which contacts a mating contact and having, at the other end, a connecting section which connects to a circuit board. A bent section is located in a middle portion between the contact section and the connecting section. An insulating housing holds the plurality of terminals. On each terminal, a bright tin-plated layer and a semi-bright tin plated layer are formed on respective surfaces of the contact section and the connecting section leaving the surface of the middle portion unplated by tin such that the semi-bright tin-plated layer is thicker than the bright tin-plated layer.

Electrical connector

A receptacle terminal includes a contact section. The contact section includes a substantially L-shaped contact spring, a first protection member, and a second protection member. The contact spring includes a link arm and a contact arm. The link arm has a first edge and a second edge opposite the first edge. The first edge extends in a mating direction of a mating terminal. The contact arm extends along the first edge and has a tip end portion connected to the first edge. The first protection member has a first link arm protection member opposing the second edge. The second protection member has a second link arm protection member opposing the first edge. The receptacle terminal thereby ensures protection of the contact spring and necessary contact pressure between the receptacle terminal and a mating terminal while having a small external size.

Receptacle terminal

A lever fitting-type connector includes a female connector, male connector and lever. The lever includes: a pair of side plates and arranged in parallel to each other, end parts of the side plates and being separated from each other having a distance therebetween; a connecting part for connecting opposite end parts of the side plates and; and fulcrum projections formed at the respective end parts of the side plates and. The lever further includes a flange part formed from an outer edge of the fulcrum projection in an outer peripheral direction. The flange part prevents the fulcrum projections from coming off from a fulcrum projection receiving part.

Lever fitting-type connector

An electrical connector includes a connector housing having a contact engaging section with contacts which engage mating contacts, and a wire holder holding wires connected to the contacts. The connector cover is capable of moving between partially engaged position and fully engaged position. The partially engaged position is the position in which a rear end of the wire holder is housed in and the fully engaged position is the position in which the rear end of the wire holder projects from a rear end opening. The connector housing has a first engaging section engaging a mating connector in the partially engaged position. The connector cover has a second engaging section engaging the first engaging section and restraining disengagement of the first engaging section from the mating connector in the fully engaged position.

Squib-type electrical connector with multiple engagement means

The present invention is to provide a connector which is not subjected to an excess force when a locking securing unit is operated to remove engagement. The connector includes a male housing, a locking arm for engaging with a locking projection of a mating connector, a locking securing unit, and deformation switching portions. The locking securing unit is movably disposed between a regulation position to regulate a resilient deformation of the locking arm and an allowance position to allow the resilient deformation thereof. The deformation switching portions have a first interfering portion disposed on the locking arm and a second interfering portion disposed on the locking securing unit. When the locking securing unit is in the allowance position, the first and second interfering portions interfere each other and the locking arm resiliently deforms to remove engagement with the locking projection. When the locking securing unit is in the regulation position, the first and second interfering portions separate each other.

A shielding shell () is integrated into a housing () by insert molding, whereas a shell connecting member () is mounted on an end of a braided wire () of a shielded cable () by crimping a crimping ring () and can be brought into contact with the inner surface of the shielding shell (). A cover () is mounted on the rear end of the housing () to retain the shell connecting member (). As the crimping ring () is crimped, ribs () are formed to project and each of them is engageable with any one of turn preventing recesses () arranged at a plurality of positions along circumferential direction on the inner circumferential surface of the cover (). Thus, the shell connecting member () is prevented from turning, thereby causing no abrasion at contact portions with the shielding shell ().

A split electrical connector housing comprises a first housing and a second housing independent from the first housing. The first housing has a plurality of contact receiving compartments and a projection extending from an outer surface thereof. The second housing has a first housing receiving opening that receives the first housing. An elastic arm is formed on an outer surface of the second housing. The elastic arm has a protrusion that extends into the first housing receiving opening and engages the projection as the first housing is received in the first housing receiving opening. The elastic arm is biased upward by the projection to change a contour of the outer surface of the second housing when the first housing is partially received in the second housing.

Electrical connector housing, electrical connector, and connector assembly

An electrical connector comprises a contact having a wire connection member and a mating contact receiving end. The mating contact receiving end includes an abutment edge and an inclined portion. A housing has a contact receiving opening with a contact receiving end. The housing has a projection extending into the contact receiving opening and a first bevelled surface opposing the projection. The first bevelled surface is arranged closer to the contact receiving end than the projection. The inclined portion engages the first bevelled surface to bias the abutment edge into the projection when the contact is incorrectly inserted into the contact receiving opening.

A connector enables a size reduction while maintaining a function of reliably preventing terminal members from falling out of terminal holes. In this connector, a plate spring piece is provided in a terminal hole of a connector housing, with a length thereof set to an axial direction of the terminal hole, and an engaging pawl protrudes from the plate spring piece. When a female terminal is inserted into the terminal hole, the engaging pawl engages with the female terminal and bends the plate spring piece downward, enabling the insertion. When the female terminal is inserted to a predetermined depth in the terminal hole, the plate spring piece returns and the engaging pawl moves into an engaging hole of the female terminal. The plate spring piece has a structure of which one length direction end portion and one side portion, along the length direction, are fixed to the connector housing.

Collision preventing projections () are provided on an outer surface of a female housing () and will contact an opening of a receptacle () of a male housing () if a main portion () of the female housing () is inserted into a receptacle () in an oblique posture. Thus, the collision preventing projections () ensure that the main portion () and male terminals () are spaced apart when the main portion () is pushed into the receptacle () in this oblique posture.

Connector with a collision preventing projection

Supporting pieces () on side surfaces of a waiting-side connector () are insertable into supporting grooves () of a casing (). Contact projections (F,R) are on one outer wall surface () of each supporting piece near the upper end and bottom ends. A squeezable projection () is on an outer wall surface () opposite from the outer wall surface () where the contact projections () are provided. The squeezable projection () has a substantially triangular cross section and contacts a wall surface (A) of the supporting groove () as insertion of the supporting piece () into the supporting groove () progresses. A tip of the squeezable projection () is squeezed at a final stage of the insertion to engage the supporting piece () with the supporting groove (). Accordingly, the waiting-side connector () is supported in the casing () without shaking.

Connector supporting structure and a squeezed amount calculating method

An attempt to fit an improper combination of housings () together brings a projection (R) of the wrong housing () into abutting engagement with an interference portion () in a fitting recess (). Abutment surfaces (Ra) are inclined in directions to move an inner peripheral surface of the fitting recess () towards an outer peripheral surface of the wrong housing (). Therefore, the fitting recess () cannot deform and spread out, and the fitting of the wrong housing () cannot proceed by force.
