A connector (10) is provided with a terminal fitting (60) to be connected to a circuit board (120), a housing (20) for accommodating the terminal fitting (60), a board accommodating portion (50) for accommodating the circuit board (120) in the housing (20), a retainer mounting hole (54) provided in the housing (20), and a retainer (80) for locking the terminal fitting (60) by being inserted into the retainer mounting hole (54). A thermal expansion difference between the retainer (80) and the circuit board (120) is set larger than that between the housing (20) and the circuit board (120).

A retainer (60) includes locking protrusions (66) projecting toward side surfaces of a housing (10). A resilient wall (18) defining a mounting hole (17) and including a part capable of interfering with the locking protrusion (66) is disposed on the side surface of the housing (10). The resilient wall (18) includes a lock receiving portion for lockably receiving the locking protrusion (66) by resilient return. An erroneous arrangement identifying portion (27) is disposed on an inner surface of the mounting hole (17) of the housing (10) for restricting an erroneous arrangement of the retainer (60) into the mounting hole (17). The erroneous arrangement identifying portion (27) is a rib-like part provided on the resilient wall (18).

A connector 10 is provided with a housing 20, a terminal fitting 30 to be accommodated into a cavity 21 of the housing 20, and a front portion 50 to be mounted on a front surface side of the housing 20. The front portion 50 includes a resilient portion 55 for pressing the terminal fitting 30 and sandwiching the terminal fitting 30 between a facing wall surface portion 21B of the cavity 21 and the resilient portion 55.

An electrical connector includes: a conductive terminal including: a connector-side connecting part; a substrate-side connecting part; and an L-shaped bent part therebetween; a housing including: a terminal-holding hole holding the conductive terminal between the connector-side connecting part and the bent part; and an opening capable of exposing the substrate-side connecting part. The opening is used for connecting a circuit substrate. An alignment member is attached toward the substrate-side connecting part of the conductive terminal so as to close the opening. The alignment member is engaged with the housing in a state where the substrate-side connecting part projects from a through hole for inserting the conductive terminal therein. The engaging unit preventing the substrate-side connecting part of the conductive terminal from moving to the bent part, is provided between the conductive terminal and the through hole.

Connector housing assemblies configured to maintain the TPA in a pre-stage condition during shipment and to facilitate the engagement of the female housing into the male housing are provided. The female housing includes a second slot for receiving a female TPA. The female housing includes a female TPA support disposed adjacent the second slot extending a predetermined distance above the female TPA so as to prevent the female TPA from being pushed into the second slot from a top down load. The male housing includes a hood configured to receive the female TPA support so as to allow the female housing to be seated within the male housing. A lip may be disposed on a proximal end of the female housing. The lip extends above a top surface of the female housing a sufficient length so as to accommodate the push of a finger or thumb.

It is aimed to prevent a noise reduction function of a twisted pair cable from being reduced near the entrances of cavities. A connector (CO) includes a twisted pair cable formed by twisting a pair of wires, female terminals (9A, 9B) connected to respective ends of both wires (W) of the twisted pair cable, a housing (15) formed with cavities (18) for individually accommodating the female terminals (9A, 9B), and a locking lance (13) deflectably arranged in the housing (15) and capable of locking the female terminals (9A, 9B). A pair of the female terminals (9A, 9B) connected to the both wires (W) of the twisted pair cable are accommodated into the cavities (18) adjacent in a Y direction and the locking lance (13) integrally and interlockably formed to straddle between the adjacent cavities (18) is formed in the adjacent cavities (18).

A dual row low profile high voltage connector, having a minimal height and meeting high voltage requirements and a method of assembling thereof, includes a male housing and a female housing, and further includes a terminal position assurance (TPA) device and a connector position assurance (CPA) device, the TPA device ensuring that a terminal, housed within the female housing, provides a secondary lock, so as to ensure that the terminal is secured or locked within the female housing. The CPA device assures that the male and female housings remain locked. The terminal is housed within the female housing to meet a minimal height requirement and having dual rows of terminals inserted therein the female. The TPA device and the CPA device function in pre-lock or full-lock positions. A method also improves clearance and creepage by allowing a clearance or electrical path to extend around an inserted TPA between terminals.

A connector includes a first housing, a second housing and a fitting assuring member. The second housing includes a first locking protrusion portion having a first slope. The fitting assuring member includes a first assuring locking portion that gets over the first locking protrusion portion to be thereby locked to the first locking protrusion portion when the first housing and the second housing are fitted to each other. The first assuring locking portion begins to slide on the first slope before completion of the fitting, and stays on the first slope until the completion of the fitting.

Included are terminal metal parts mounted on ends of electric wires, a housing housing the terminal metal parts at a housing completion position thereinside and to be inserted and fit into a counterpart fitting portion headed by a tip, a terminal locking member mounted on the housing from outside along a direction crossing an insertion direction of the housing to the counterpart fitting portion and locking the terminal metal parts as they are at the housing completion position at a mounting completion position with respect to the housing, and a front holder causing the housing to be inserted headed by the tip and locking the terminal locking member at the mounting completion position.

A method for improving clearance and creepage in a male high voltage connector assembly using a male terminal position assurance (TPA) device. The male high voltage connector assembly is highly suitable for high voltage electrical terminals, which are larger terminals. The method includes a step of allowing a clearance and creepage or electrical path to extend from at least a high voltage electrical terminal to a male outer housing of the high voltage connector assembly. When the TPA device is inserted and locked within a male inner housing of the high voltage connector assembly, the clearance and creepage or electrical path extends from the high voltage electrical terminal along at least a surface of the TPA device and to the male outer housing of the high voltage connector assembly. The male TPA device includes wing-like shape members with intermediate members that extend substantially and respectively downward from the wing-like shape members.
