ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector for use in a wiring harness for motor vehicles, and more particularly to an incomplete insertion correcting method of a terminal inserted to be locked in a terminal accommodating chamber of a connector housing, and an incomplete insertion correcting jig used therefore.
2. Description of the Prior Art
In
FIG. 27
, a terminal c inserted into a terminal accommodating chamber b of a connector housing a is locked as a primary locking by a resilient locking piece d which is integrally formed in the connector housing a, and further, a locking tool f connected to the connector housing a by way of a hinge e is inserted into the terminal accommodating chamber b through an opening a
1
as is done in the lower chamber in
FIG. 27
so as to confirm the primary locked state, and A simultaneously the front end of the locking section f
1
of the locking tool f is fitted with a shoulder portion c
1
of the terminal c as a secondary locking for preventing the rear end thereof from coming off (Japanese Utility Model Published No. Heisei 2-49656).
Also, in
FIG. 28
, from the state that the same terminal is inserted into a terminal accommodating chamber b′ and locked by a resilient locking piece therein as a primary locking, a locking tool f′, which is constructed as a separate body from the connector housing a′, is inserted into the terminal accommodating chamber b′ through an opening a
1
′to be further locked as a secondary locking (Japanese Patent Application Laid Open No. 64-54678).
In the above situation, the secondary locking between the locking tools f, f′ and the terminal c can not be performed if the terminal c is not completely inserted and primarily locked by the resilient locking piece d, as a proper insertion of the locking tools f, f′ is hampered by the incompletely inserted terminal c, so that a perfect primary locking of the terminal is essential to enable a complete insertion of the locking tools f, f′ into the terminal accommodating chamber. However, the modern technology provides a sufficient locking force for preventing the inserted terminal from coming off even only with a primary locking made by the resilient primary licking piece, and besides these secondary locking tools cause a raise of the manufacturing cost as a whole.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above-mentioned points, and accordingly, it is an object of the present invention to provide an apparatus and a method, by which an incomplete insertion of a terminal in a terminal accommodating chamber of a connector housing can be corrected or checked, even without using a secondary locking tool.
In order to attain the above objective, the present invention provides a connector engagement correcting method for correcting an incomplete insertion of a terminal inserted into a connector housing, wherein the terminal is received in a terminal accommodating chamber in the connector housing and locked by a resilient locking piece provided in the chamber on completion of an insertion of the terminal, which method comprising the steps of; inserting a tip end of an inserted position correcting jig into an opening formed in a peripheral wall which is extendedly provided from the rear end of the connector housing; shifting the inserted position correcting jig toward the connector housing pivoting on the opening to fit it with a rear end portion of the terminal which is still in an incompletely inserted state; and pushing the terminal to a completely inserted position thereof, wherein a correcting operation checking member formed in the opening is forcibly activated to deform an external appearance of the opening when the tip end of the jig is inserted into and engaged with the opening. In the above method, the correcting operation checking member can be formed in an inner surface of the peripheral wall extendedly provided from the rear end of the connector housing, so that it is forcibly activated by the jig to deform an external appearance thereof on completion of the correcting operation performed by a shifting movement of the jig, and further, the correcting operation checking member can be formed in an another opening formed in the peripheral wall provided extendedly from the rear end of the connector housing, so that it is forcibly activated by the jig to deform an external appearance thereof on completion of the correcting operation performed by a shifting movement of the jig.
Alternatively, the present invention provides a connector engagement correcting method for correcting an incomplete insertion of a terminal inserted into a connector housing, wherein the terminal is received in a terminal accommodating chamber in the connector housing and locked by a resilient locking piece provided in the chamber on completion of an insertion of the terminal, which method comprising the steps of; shifting an inserted position correcting jig across a plurality of terminal accommodating chambers between jig insertion holes formed in the opposite side walls of the connector housing; engaging a tapered activating section formed at a tip end of the jig with an intermediate portion of each of the plurality of terminals still in an incompletely inserted state; pushing each of the terminals into a completely inserted position thereof, wherein a correcting operation checking member formed in each of the insertion holes is forcibly activated to deform an external appearance of each of the insertion holes when the tip end of the jig is inserted into and engaged with the jig insertion holes.
Alternatively, the present invention provides a connector engagement correcting method for correcting an incomplete insertion of a terminal inserted in a connector housing, wherein the terminal is received in a terminal accommodating chamber in the connector housing and locked by a resilient locking piece provided in the chamber on completion of an insertion of the terminal, which method comprising the steps of; inserting a tip end of an inserted position correcting jig into a pivot center formed in one side of a peripheral wall extendedly provided at the rear end of the connector housing; shifting the inserted position correcting jig toward the connector housing pivoting on the pivot center to fit it with a rear end portion of the terminal which is still in an incompletely inserted state; and pushing the terminal to a completely inserted position thereof, wherein a correcting operation checking member formed in the other side of the peripheral wall is forcibly activated by the jig to deform an external appearance of the wall when the correcting operation of the checking member is performed by the shifting movement of the jig, wherein the correcting operation checking member can be formed in a bridge-like shape within an opening of the wall.
In these above methods, the opening as an insertion hole of the jig is enabled to receive a checking projection on the base frame of a connector checking tool for checking an electrical conduction of the terminal by being enlarged resulted from a removal of the correcting operation checking member.
Alternatively, the present invention provides a connector engagement correcting method for correcting an incomplete insertion of a terminal inserted into a connector housing, wherein the terminal is received in a terminal accommodating chamber in the connector housing and locked by a resilient locking piece provided in the chamber on completion of an insertion of the terminal, which method comprising the steps of; inserting a tip end of an inserted position correcting jig into a pivot center formed in a peripheral wall which is extendedly provided from the rear end of the connector housing; shifting the inserted position correcting jig toward the connector housing pivoting on the pivot center to fit it with a rear end portion of the terminal which is still in an incompletely inserted state; and pushing the terminal to a completely inserted
