Description

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In FIG. 1 , a plurality of terminals C each preliminarily connected to a wire W are inserted into a plurality of terminal accommodating chambers 1 , wherein each terminal C is locked by a resilient locking piece 2 integrally formed within each of the terminal accommodating chambers when it is perfectly inserted, and is thereby prevented from coming off (see FIG. 3 ).

In the rear side of the connector housing A 1 , the terminal accommodating chamber 1 is formed with a rearward projecting peripheral wall 3 with its lower wall face 3 a notched therefrom, and an opening 4 that functions as a pivot center for an inserted position correcting jig (explained later) is formed on the upper side of the peripheral wall 3 , while a correcting operation checking member 4 a of a cantilever projection type is protruded into the opening 4 through a thin portion 4 b thereof.

T 1 is an inserted position correcting jig for correcting the position of the incompletely inserted terminal C′ (FIG. 3 ), and formed with a pectinate pushing section 6 at the far end of the holding section 5 thereof. The pectinate pushing section 6 is further formed with a pivoting section 6 a at its center portion, whose end portion is slightly protruded and formed with a cutting blade 6 c forming also a wire receiving sections 6 b at respective sides thereof.

In the above construction, the jig T 1 is first placed rather obliquely against the connector housing A 1 from the lower rear side thereof, and then the pivot section 6 a thereof is inserted into the opening 4 , receiving the wires W simultaneously in the wire receiving sections 6 b . By this operation, the cutting blade 6 c cuts off the protruded correcting operation checking member 4 a through the thin portion 4 b thereof (FIG. 3 ). Then, when the jig T 1 is rotated in the direction of the connector housing A 1 pivoting on the opening 4 , the opposite sides 6 d of each of the wire receiving sections 6 b of the pectinate pushing section 6 abut A against the wire coat crimped portion C 1 of the incompletely inserted terminal C′ (FIG. 4 ), so that the terminal C′ is shifted to the completely inserted position to be locked by the resilient locking piece 2 (FIG. 5 ).

In the embodiment shown in FIGS. 6A and 6B , the correcting operation checking member 4 a ′ is quite thin, and thus it is broken by use of the jig T 1 (FIG. 6 B).

In the embodiment shown in FIGS. 7A and 7B , the correcting operation checking member 4 a ″ is a portion bent by way of a hinge 4 b ″, and is deformed outwardly when the jig T 1 is activated (FIG. 7 B).

In the embodiment shown in FIG. 8 , a vertically aligned pair of openings 4 each functioning as a pivot center for an inserted position correcting jig and having a protruded correcting operation checking member 4 a is formed either in the right or left side face of the peripheral wall 3 ′protruded from the rear end of the connector housing A 2 , wherein the protruded type correcting operation checking member 4 a is formed in the inner surface of the other side face of the protruded wall 3 ′ opposing to the opening 4 .

The inserted position correcting jig T 2 is formed with a vertically aligned pair of stick-like pushing sections 6 ′sidewardly extending from the front end portion thereof, wherein each of the stick-like pushing sections 6 ′ is formed with a cutting blade 6 c ′ at the far end thereof, and an abutting portion 6 e ′ to be fitted with the end portion of the protruded wall 3 is formed at the base portion of the stick-like pushing sections 6 ′.

When using the inserted position correcting jig T 2 , the cutting blades 6 c ′ of each of the respective stick-like pushing sections 6 ′ is first inserted obliquely through the spaces between the wires W into the opening 4 , and then the base portion of the stick-like pushing sections 6 ′ is rotated in the direction toward the connector housings A 2 until the abutting portion 6 e ′ thereof is abutted against the rearwardly extended wall 3 ′, wherein the front side section 6 d ′ of each of the stick-like pushing sections 6 ′ is fitted with the crimped portions of the incompletely inserted wires of the terminals so as to shift the terminals to the perfectly inserted position.

When the cutting blades 6 c ′ of each of the stick-like pushing sections 6 ′ is inserted into the opening 4 , the protruded correcting operation checking member 4 a is cut off, and when the insertion is completed, each of these checking members 7 is removed by the front side section 6 d ′ of the respective pushing sections 6 ′ (FIG. 9 ).

In the embodiments shown in FIGS. 8 and 9 , the correcting operation checking member 4 a can be formed by a thin flange, a bent section supported by a hinge or the like instead of the above protruded form.

In the embodiment shown in FIG. 10 , a pair of openings 4 , 4 that functions as a pivot center can be formed in the opposite side wall faces of the rearwardly protruded peripheral wall of the connector housing A 2 ′ in a face-to-face relation, and at the base portion of each of the stick-like pushing sections 6 ′ of the jig T 2 ′, an activating projection 6 g ′ is formed in an adversely protruding manner.

In this case above, it is possible to disregard the orientation of the jig T 1 in use, wherein when the pushing operation of the stick-like pushing section 6 ′ is completed, the activating projection 6 g ′ also inserts into the other opening 4 formed in the opposite side wall, pushing against the side wall of the connector housing A 2 ′ so as to force to remove the checking member 4 a.

In the embodiment shown in FIG. 11 , in the opposite side walls 8 , 8 of the connector housing A 3 , a jig insertion hole 9 for receiving the jig T 3 is formed in a vertically extending manner across the terminal accommodating chambers 1 , 1 , wherein a pair of protruded type correcting operation checking members 9 a , 9 a are formed respectively from the upper and lower sides of the jig insertion hole 9 in an inwardly projecting manner.

The jig T 3 is formed with a pair of stick-like pushing sections 6 ″, 6 ″ extending respectively from the upper and lower portions of the holding section 5 ″ thereof, and each of the stick-like pushing sections 6 ″ is formed with a cutting blade 6 c ″ at the far end thereof and also with a tapered activating section 6 f ″ facing in the forward direction of the connector housing A 3 .

In the above construction, a through-hole (not shown) for receiving the stick-like pushing section 6 ″ is formed in the lateral sides of the respective separating wall 8 ′ formed in the terminal accommodating chamber of the connector housing whereby each of the stick-like pushing sections 6 ″ of the jig T 3 can be inserted from one side wall 8 to the other side wall 8 , and on inserting the pushing section 6 ″, the correcting operation checking members 9 a , 9 a are removed by a pair of the cutting blades 6 c ″, 6 c ″, and simultaneously the tapered activating sections 6 f ″, 6 f ″ of the jig T 3 are fitted with the respective shoulder portions C 2 ( FIG. 12 ) of each of the incompletely inserted terminals C′ to force the terminal C′ forward so as to be locked by the respective resilient locking pieces 2 ′.

Even in the embodiments shown in FIGS. 11 , 12 , the correcting operation checking member 9 a can be formed by a thin flange, a bent section supported by a hinge or the like.

In the connector housing A 4 shown in FIG. 13 , in addition to the construction of the connector housing A 1 , a pair of openings 11 , 11 each having a bridge-like correcting operation checking member 11 a therein are provided at the opposite lateral sides of the rear end of the bottom wall 10 adjacent to the notched section 3 a of the protruded peripheral wall 3 . Further, as shown in FIG. 14 , a pair of cutting blades 6 c ′″ corresponding to the bridge-like correcting operation checking members 11 a , 11 a are protrudedly provided on the opposite lateral sides of the base portion of the pectinate pushing section 6 of the jig T 4 .

When the jig T 4 is used, each of the cutting blades 6 c ′″ cuts off the corresponding bridge-like correcting operation checking member 11 a of the connector housing A 4 at the final stage of the correcting operation in addition to the procedures shown in FIG. 3 to FIG. 5 , whereby the openings 11 , 11 are opened toward the rear end of the housing ( FIGS. 16 , 17 ). It is to be noted that the correcting operation checking member 4 a of the opening 4 can be, in this case above, omitted.

FIG. 18 shows a terminal detecting device S of the connector, wherein a connector holding section 13 is fixed onto one side of the base frame 12 , and a detecting section 14 provided facing to the connector holding section 13 can be activated by a lever for putting it nearer or farther to or from the holding section 13 . In the detecting section 14 , 18 electrically conductive pins 16 corresponding to each of the terminal accommodating chambers of the connector A 4 are provided, wherein each of the pins 16 is brought into contact with the corresponding terminal and electrically checked by a detecting circuit formed by way of the wires W 1 and W 2 so as to detect whether or not the terminals have been correctly inserted into the terminal accommodating chambers.

In this case, on the base frame 12 at the connector holding section 13 a checking projection 17 is protrudedly provided to be received by the openings 11 , 11 formed at the rear end of the connector housing A 4 (FIG. 19 ), so that if the correcting operation has not been performed to the final stage, the bridge 11 a of each opening 11 still exists to hamper a setting of the connector housing A 4 on the terminal detecting device S, thereby detecting an incomplete correction of the insertion. It is to be noted that the same detection of the correcting operation of an incomplete insertion of the terminals can be applied to the connector housings A 1 , A 2 , A 2 ′ and A 3 which are all provided with correcting operation checking members formed in the openings provided in the respective peripheral walls to be removed on the correcting operation.

In addition, a checker pin 31 can be provided in the detecting device, as shown in FIG. 18 , in order to electrically inform that the parts to be removed on the correcting operation of the above connector housings A 1 , A 2 , A 2 ′ and A 3 , are not removed yet.

In the embodiment shown in FIG. 20 , an opening 18 is provided in one side wall of the connector housing A 5 , and also at one side periphery 18 ′ of the opening 18 , a thin free end 18 a 1 of a correcting operation checking member 18 a composed of a resilient cantilever is fitted with the periphery 18 ′ from inside thereof.

With the construction above, when the pivoting section 6 a of the pectinate pushing section 6 is inserted into the opening 4 and rotates jig T 5 toward the connector housing A 5 , the pectinate pushing section 6 pushes the incompletely inserted terminal in the same way as mentioned heretofore, and simultaneously one side part 6 d ″ abuts against the expanded portion 18 a 2 of the correcting operation checking member 18 a to push it outwardly, and when the operation is completed, the thin free end 18 a 1 is pushed outside the opening 18 and is maintained at the same state (FIG. 21 B).

In the embodiment shown in FIGS. 22A , 22 B and 22 C, at the rear end of the connector housing A 6 , a notched portion 19 and a frame 20 are integrally formed at the respective side portions in the top wall 19 thereof, an opening 22 is formed at the respective side walls 21 , 21 , and also inside the each opening 22 , a resilient correcting operation checking member 22 a with respect to the terminal C is formed with its free end 22 a 1 directed rearwardly ( FIGS. 23A , 23 B).

In the jig T 6 , a fitting section 23 is formed upright from the forwardly protruded end of the upper front portion of the lateral opposite sides of the jig T 6 in such a manner as to intersect with the extending direction of the pectinate portion 6 ′, while below the fitting section 23 an activating piece 24 is protrudedly provided for pushing the correcting operation checking member 22 a.

In using the jig T 6 , each of the fitting sections 23 is first inserted into the corresponding frame 20 through the notched portion 19 a and locked thereby (FIG. 22 B), and then by rotating the jig T 6 toward the connector housing A 6 pivoting on the frame 20 (FIG. 22 C), projections 6 h ′respectively formed at the end peripheral portions of the wire accommodating sections 6 b ′ abut against wire coat crimped section C 1 of the incompletely inserted terminals C′so as to shift the terminals C′ to a properly inserted position, and put them to the completely inserted position where the terminals are locked by the resilient pieces.

In rotating the jig T 6 , when the activating piece 24 is inserted into the correcting operation checking member 22 a by way of the tapered activating section 24 a thereof, the free end section 22 a 1 of the checking member 22 a is forced to deform toward the opening 22 (FIG. 23 A), and when the operation is completed, it is pushed outward from the opening 22 to be locked by the stop bar 25 (FIG. 23 B).

In the embodiment shown in FIGS. 24A and 24B , between a pair of vertically aligned protecting projections 27 , 27 at the rear end of one side wall 26 of the connector housing A 7 , a correcting operation checking member 27 a is provided in a bridge-like form by way of a resilient hinge 27 b and a thin supporting section 27 c , while provided in the forward direction of the correcting operation checking member 27 a formed on the side wall 26 is a locking projection 28 .

In the jig T 7 , each of a pair of pushing sections 6 ′, 6 ′provided to the holding section 5 ′ is formed respectively with a pivot projection 6 i , an activation rod 29 is provided between the holding section 5 ′ and the pair of pushing sections 6 ′, 6 ′, which rod 29 being further formed with a blade section 29 a and an activating section 29 b at the front portion thereof.

When using the jig T 7 , each of the pivot projections 6 i is first fitted into an opening 30 formed in the side wall of the connector housing A 7 (FIG. 26 A), and then the holding section 5 ′ is rotated toward the connector housing to fit the pushing section 6 ′ thereof to the upright piece C 2 of the wire crimped portion C 1 provided at the rear end of the incompletely inserted terminal C′ to shift the terminal to a perfectly inserted position where it is locked by the resilient piece 2 ( FIGS. 26B , 26 C).

During the rotating operation of the jig T 7 , the blade section 29 a of the activation rod 29 first cuts the thin supporting portion 27 c and at the same time the activating section 29 b pushes the correcting operation checking member 27 a in the lower diagonal direction, bending the resilient hinge section 27 b simultaneously, whereby the projection 27 a 1 of the member 27 a is engaged with the locking projection 28 to be locked thereby.

In this embodiment, since the correcting operation checking member 27 a is provided at the external side of the side wall, and exposed outside, the deformation of the correcting operation can be easily observed from outside, and in addition, the deformed state of the checking member 27 a is securely maintained between a pair of protecting projections 27 , 27 .

[Effect of the Invention]

Since the present invention is constructed as above, an incompletely inserted terminal in a connector housing is shifted to a perfectly inserted position and securely locked in the perfectly inserted position by operating an inserted position correcting jig, and also whether or not the correcting operation is done can be checked by a removal or deformation of the correcting operation checking member, and further since an opening, which is enlarged by the removal of the correcting operation checking member, receives a fitting member at a predetermined position of a base frame of an electrical conduction checking tool and thereby to enable a setting of the connector, a perfectly locked state of the terminal can be further checked.

While the invention has been described with reference to specific embodiments, the description is illustrative and is not to be construed as limiting the scope of the invention. Various modifications and changes may occur to those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
