One connector housing includes a resilient locking arm having a through-hole provided at its tip, a pair of detection terminals attached to said resilient locking arm and opposed to the through-hole, a first spring portion provided on the side of a warping space of the resilient locking arm and inserted between the resilient locking arm and the pair of detection terminals, the first spring portion having a protrusion to be engaged in said through-hole so as to force the locking arm in an anti-warping direction, and a second spring portion always forcing said resilient locking arm in the anti-warping direction. Another connector housing includes an engagement protrusion which is to be engaged in the through-hole to push the protrusion, thereby warping the first spring portion in an anti-forcing direction to be brought into contact with the pair of detection terminals. Thus, connector fitting of one and another connector housings can be surely detected electrically. The fitting detection connector can have a buffer spring member which is arranged between the contact portion and intrusion protrusion of the first spring portion.

Disclosed is a terminal retainer mounted on a rear portion of a connector housing so as to move in a two-stage manner, that is, between a provisionally-connected condition and a completely-connected condition, and in the completely-connected condition the terminal retainer can be positively engaged with metal terminals. Flexible support pieces for metal terminals are provided on a terminal retainer. A flexible retaining piece for the metal terminal is provided at each terminal receiving chamber. In the provisionally-connected condition of the terminal retainer, the flexible support piece is placed on a push-up projection of the connector housing to be held out of a path of movement of the metal terminal within the terminal receiving chamber. When the terminal retainer shifts to the completely-connected condition, a driven projection on the flexible support piece is engaged in a drive groove in the connector housing to forcibly drive the flexible support piece into engagement with the metal terminal.

A connector comprises a connector housing with a plurality of terminal accommodating chambers and a rear holder which to be inserted into and coupled with a rear end of the connector housing for restricting pulling-up of terminals inserted respectively into the terminal accommodating chambers. A stopper body which is coupled on a rear section of the rear holder through a hinge section and which is interchangeable between a laid-down condition extending along an inserting direction of the rear holder and a standing-up condition which intersects with the laid-down condition is engaged with the rear end of the connector housing in a tentative locking state when the stopper body is biased into the standing-up condition. The stopper body is brought to the laid-down condition in a complete locking state so as to be accommodated within the rear end of the connector housing. A plurality of indication marks are displayed on a rear face of the stopper body when the stopper body is in the standing-up condition to indicate accommodation of the terminals into the respective terminal accommodating chambers.

In a primary molding step, a connector housing having a hood portion is molded. In a secondary molding step, an elastic seal ring is molded on an inner side of the hood portion. Through holes are formed in the connector housing in the primary molding step which allow an elastic material to flow therethrough from a seal ring-forming portion on the inner side of the hood portion to an outer side of the hood portion, and which retain part of the seal ring formed at the seal ring-forming portion when the elastic material is cured. An air reservoir portion is formed in a secondary mold, which communicates with outer open ends of the through holes in the connector housing in the secondary molding step.

A method for shifting a terminal which has been incompletely inserted into a terminal accommodating chamber of a connector housing of a connector for use in a wiring harness for motor vehicles to completely insert the terminal by the use of an inserted position correcting jig is provided. The method includes inserting a front end portion of the inserted terminal position correcting jig into an opening formed in a peripheral wall extending from a rear portion of the connector housing. The opening functions as a pivot center and has a correcting operation checking member therein to thereby shift the jig toward the housing pivoting on the opening. The jig is thus fitted with the rear end portion of the terminal which is still in an incompletely inserted state so as to shift the terminal to a completely inserted position and securely lock the terminal. Since the correcting operation checking member formed in the opening is removed when the front end portion of the jig is inserted, whether or not the correcting operation is perfectly done can be checked from outside by a removal or deformation of the correcting operation checking member.

The present invention relates to a connector for use in a wiring harness for motor vehicles, and more particularly to a method for shifting a terminal, which is in an incompletely inserted state in a terminal accommodating chamber of a connector housing, to a completely inserted position thereof by use of an inserted position correcting jig.As a general procedure of the above method, a front end portion of the inserted terminal position correcting jig is inserted into an opening formed in a peripheral wall provided extendedly from the rear portion of a connector housing, which opening functioning as its pivot center and having a correcting operation checking member therein, thereby to shift the jig toward the housing pivoting on the opening, and by this operation the jig is fitted with the rear end portion of the terminal which is still in an incompletely inserted state so as to shift the terminal to a completely inserted position and securely locked, wherein since the correcting operation checking member formed in the opening is removed when the front end portion of the jig is inserted, whether or not the correcting operation is perfectly done can be checked from outside by a removal or deformation of the correcting operation checking member.
摘要:
A case having a case body, in which a plurality of terminal accommodating chambers are formed in parallel, and an elastic waterproof portion, which is formed integrally with the case body and which has a plurality of wire insertion holes into which covered wires are inserted in a waterproof state is inserted through an opened portion of a connector housing so that the elastic waterproof portion is fitted to the opened portion in a waterproof state. Therefore, when the covered wires are inserted into the wire insertion holes, the projecting portions of the covered wires simply are required to be adjusted to have a predetermined length. Thus, the necessity of furthermore adjusting the projection portion when the solderless connection is established can be eliminated. Since the elastic waterproof portion is formed integrally with the case body, pressure cannot easily act on the portions in which the solderless terminals and the covered wires are solderless-connected to one another even if the elastic waterproof portion is strongly pressed to the inside of the opened portion. Therefore, the electrically conductive state between the solderless terminals and the covered wires can be maintained.
