Appl. No.:

10/713955

Inventors:

Tsuyoshi Osada - Novi MI, US

Assignee:

J. S. T. Mfg. Co., Ltd. - Osaka

International Classification:

H01R029/00

US Classification:

439188, 439352

Abstract:

The objective is to ensure the inflator yields a force sufficient to hold the shunt, prevent the shunt from coming off the inflator, reduce the force required to insert the shunt into the socket, and enhance the workability of assembling the shunt into the socket. The shunt body is provided with a short-circuit piece which short-circuits the pair of pins of the squib, and the shunt body is provided with a protrusion being formed of a flexible material, the root end of the protrusion is provided on the outer face of the shunt body, the protrusion extends from the root end thereof in a direction tilting toward the outside from the shunt body at an angle within 90 degrees to a direction being parallel to the central axis of the shunt body and heading toward the top thereof, and it is arranged that when the top end of the protrusion is pushed toward the connection hole of the shunt body, the protrusion will undergo deformation by bending, and when the shunt body fits into the socket, the protrusion will restitute to protrude in the fitting concave.

International Classification:

H01R 13/627

US Classification:

439352, 439489

Abstract:

A housing assembly for a pair of electric connectors includes a first housing with a lock arm to lock the first housing inserted into a second housing, and a reinforcing member held by the first housing. The reinforcing member can be pushed into the first housing only when the first housing and the second housing are completely properly fitted together. The coupling strength between the housings is enhanced by the coupling strength of the reinforcing member, and the operator can easily and properly judge the proper fitting of the housings on the basis that the reinforcing member can be pushed in. As the first housing holds the reinforcing member, the fitting work can be done smoothly and reliably. Both housings can be made slimmer. This assembly allows a single-action fitting wherein the first housing can be fitted in the second housing by pushing only the reinforcing member.

J.S.T. Corporation - Farmington Hills MI

International Classification:

H01R 13/40

US Classification:

439595

Abstract:

An electrical connector includes a housing and a terminal position assurance member, which is inserted into the housing. The housing has a front receiving portion and a rear receiving portion, which receives a terminal of a wiring harness. The housing also has a recess disposed at a top, front portion thereof. The terminal position assurance member has a protrusion disposed on a top thereof and configured to be fitted into the front receiving portion. The terminal position assurance member assures a position of the terminal of the wiring harness. The protrusion of the terminal position assurance member engages with the recess, and thereby the terminal position assurance member is locked in the housing.

Inventors:

Tsuyoshi Osada - Farmington Hills MI, US

Assignee:

J.S.T. Corporation - Farmington Hills MI

International Classification:

H01R 13/62

US Classification:

439157

Abstract:

An electrical connector includes a housing and a lever supported pivotally on at least one pivot disposed on the housing. The lever rotates on the pivot within a range from a pre-engagement position to a final engagement position. The lever also has a recess configured to fit a boss disposed on a mating connector therein in accordance with rotational movement of the lever. Further, the lever includes a connector locking portion disposed on a beam thereof. The connector locking portion includes a base portion extending downward from the beam, a flap portion supported by the base portion and extending in a direction substantially tangent to the rotational movement, and a detent disposed in proximity of a first free end of the flap portion such that the detent engages with an engaging portion disposed on the housing at the final engagement position.

International Classification:

H01R 13/62

US Classification:

439157, 439372

Abstract:

An electrical connector includes a housing and a lever supported pivotally on a pivot disposed on the housing. The lever is configured to rotate on the pivot within a range from a pre-engagement position to a final engagement position. The lever includes a recess configured to accommodate a boss disposed on a mating connector therein in accordance with rotational movement of the lever. The lever also includes a locking mechanism having a detent to engage with an engaging portion disposed on the housing at the final engagement position. Further, the housing includes a movable stopper disposed on a surface thereof. The movable stopper engages with an edge portion of the lever at the pre-engagement position. When combined with the mating connector, the movable stopper primarily interferes with the boss, and is displaced so as to release the engagement with the edge portion of the lever. Thus, the engagement with the edge portion is released, and thereby the lever freely rotates on the pivot, while the boss is being fitted into the recess.

Assignee:

J.S. T. Corporation - Farmington Hills MI

International Classification:

H01R 13/514

US Classification:

439752

Abstract:

An electrical connector includes a housing and a terminal position assurance (TPA) member, which is inserted into the housing. The housing has a front receiving portion and a rear receiving portion, which receives a terminal of a wiring harness. The housing also has a base portion and a recess, which is formed by the base portion, disposed at a top, front portion thereof. Further, an incision is disposed adjacent to the base portion of the housing, thereby allowing an end portion of the base portion to be slightly moved. The TPA member has a protrusion disposed on a top thereof and configured to be fitted into the front receiving portion. The TPA member assures a position of the terminal of the wiring harness. The protrusion of the TPA member engages with the recess, and thereby the TPA is locked in the housing.

Abstract:

A connector includes a housing and a terminal portion disposed on the housing. A tine plate has a first surface, an oppositely facing second surface, a plurality of through-holes passing from the first surface to the second surface, and at least one opening passing from the first surface to the second surface. A plurality of tines are disposed on the terminal portion. Each tine extends through a corresponding one of the through holes in a direction from the first surface toward the second surface. At least one protrusion is disposed on the housing, extending at least partially through the respective at least one opening in the direction from the first surface toward the second surface. The at least one protrusion engages the tine plate along a perimeter of the at least one opening at two or more contact points.
