In a fitting connector, a latch hold body includes a first fulcrum portion provided on a latch-release arm portion and exerting force in a detaching direction from a second latch hold portion on a first latch hold portion with a contact point with a first release-operation force receiving portion as a fulcrum when a latch-release operation portion is pushed, and a second fulcrum portion provided on the latch-release operation portion side relative to the first fulcrum portion in the latch-release arm portion and exerting the force in the detaching direction from the second latch hold portion on the first latch hold portion with a contact point with a second release-operation force receiving portion that contacted along with continuation of push operation as a new fulcrum.

An electrical connector having electrical terminals and a housing. The housing has a terminal-receiving portion with terminal-receiving cavities for receiving the electrical terminals therein. At least one latch-receiving slot is positioned between adjacent terminal-receiving cavities. A cover portion is provided for covering the terminal-receiving cavities and the terminals. The cover portion has latches which cooperate with the at least one latch-receiving slot when the cover portion is moved to a closed position. A hinge portion connects the terminal-receiving portion to the cover portion. The hinge is deformable to allow the cover portion to move between an open position in which the terminals can be inserted and removed from the terminal-receiving cavities of the terminal-receiving portion and the closed position in which the terminals are secured in the terminal-receiving cavities of the terminal-receiving portion.

A connector includes: a housing having a lock portion; and a fitting assuring component attached to the housing and detecting whether the housing and the counterpart housing being fitted with each other. The fitting assuring component has a hollow portion to house at least part of the lock portion to surround the at least part of the lock portion upon the fitting assuring component being located at the preset attachment position, and the fitting assuring component preventing the lock portion from switching to cancellation of the state of the housing and the counterpart housing being fitted with each other by interfering with an inside wall of the hollow portion.

A connector including a male housing and a female housing is provided. A beak portion of the male housing has a push-back surface provided on a front side of the male housing with a top portion of the beak portion as a boundary and inclined outward gradually toward a rear side of the male housing, and a pull-in surface provided on the rear side of the male housing with the portion of the beak portion as a boundary and inclined inward gradually toward the rear side of the male housing. When the locking claw of the locking arm of the fitting assurance member reaches a boundary between the locking projection of the male housing and the lock piece of the female housing, the pressing claw of the elastic arm in the fitting assurance member is disposed on the pull-in surface side over the top portion of the beak portion.

A method of making an electrical connector which includes an insulative housing having a tongue with two opposite surfaces and plural contacts with contacting portions exposed to the two opposite surfaces of the tongue, characterized by the steps of: forming the plural contacts from a single contact carrier to have one contact thereof with a contacting portion oriented reversely-symmetrically with respect to a contacting portion of another contact thereof; insert-molding the plurality of contacts with an insulator to form the insulative housing while exposing front ends of the contacts; and severing a carrier strip of the contact carrier from the front ends of the contacts while leaving the front ends inwardly of a front end surface of the insulative housing.

A ground connection structure for an electrical connection box and a fixation object, includes a first ground contact portion provided on the fixation object, a second ground contact portion provided on the electrical connection box and electrically connected to the first ground contact portion when the electrical connection box is fixed to the fixation object, a ground circuit body provided in the electrical connection box and electrically connected to the second ground contact portion, and a fixing member configured to fix the electrical connection box to the fixation object such that the second ground contact portion is brought into contact with the first ground contact portion.

A dual orientation connector having a connector tab with first and second major opposing sides and a plurality of electrical contacts carried by the connector tab. The plurality of contacts includes a first set of external contacts formed at the first major side and a second set of external contacts formed at the second major side. The first plurality of contacts are symmetrically spaced with the second plurality of contacts and the connector tab is shaped to have 180 degree symmetry so that it can be inserted and operatively coupled to a corresponding receptacle connector in either of two insertion orientations.

An electrical plug connector includes a plug housing having a wall with a first opening. A contact element holder surrounds the first opening. A collar extends from the wall, surrounding the contact element holder. A fixing element is detachably attached to the contact element holder and radially surrounds the contact element holder and part of the contact element holder. First protrusions project from the fixing element between the fixing element and the collar. Second protrusions project from an inner surface of the fixing element into the contact element holder. The first protrusions and the second protrusions are designed in so that after fitting the plug housing together with a mating plug housing, a collar of the mating plug housing engages the first protrusions, whereby the first protrusions are pressed inwards and whereby the second protrusions are pressed inwards against an electrical contact element held in the contact element holder.
