Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector provided with a retainer.

[0002]

2. Description of the Related Art Conventionally, there has been a side retainer type connector in which a retainer is inserted from a side surface of a housing and directly engaged with a terminal fitting as one type of connector provided with a retainer, one example of which is disclosed in Japanese Patent Laid-Open No. 4-137474. Have been described. As shown in FIGS. 11 (A) and 11 (B), this one has a structure in which a retainer 3 is inserted into a retainer mounting hole 2 that opens downward in a housing 1 from a rear side in a cavity 4 in a state where a retainer 3 is inserted at a temporary locking position. After inserting the terminal fitting 5, the retainer 3 is pushed into the upper main locking position so that the locking portion 6 of the retainer 3 enters the cavity 4 and the terminal fitting 5
It is adapted to be directly engaged with the engaged portion 7 to prevent the detachment. On the other hand, when the retainer 3 is pushed into the main locking position with the terminal fitting 5 held in the half-inserted state before reaching the normal depth, the locking portion 6 hits the lower surface of the terminal fitting 5. Then, the pushing of the retainer 3 is restricted,
Therefore, it is detected that the terminal fitting 5 has been half-inserted.

[0003]

By the way, between the retainer mounting hole 2 and the retainer 3 in the housing 1,
Usually, a predetermined clearance is provided in consideration of the workability of assembling the retainer 3. However, since the retainer 3 and the housing 1 are both made of synthetic resin,
It is difficult to avoid dimensional error during molding, and the retainer 3 assembled to the housing 1 may rattle back and forth depending on its size. Then, retainer 3
Is attached in a state of being displaced rearward from the illustrated normal position (position where the front surface of the engaging portion 6 and the front surface of the hole edge of the retainer mounting hole 2 are in contact with or close to each other), and the terminal fitting 5 is half-inserted. However, there is a possibility that the retainer 3 may be attached to the main locking position, resulting in the half insertion of the terminal fitting 5 being overlooked. The present invention has been completed based on the above circumstances, and an object thereof is to reliably detect half insertion of a terminal fitting.

[0004]

As means for achieving the above object, the invention of claim 1 is a connector housing provided with a cavity into which a terminal fitting can be inserted, and a normal depth inserted into the cavity. In a connector including a lance capable of elastically retaining and retaining the terminal fitting, and a retainer capable of being attached to the connector housing and retaining and holding the terminal fitting inserted into the regular depth, At least one of the connector housing and the retainer is moved to a position where the retainer can interfere with the terminal fitting or the lance bent by the terminal fitting when the terminal fitting is half-inserted. The present invention is characterized in that the retainer is provided with a correction portion that can be corrected.

According to a second aspect of the present invention, in the apparatus according to the first aspect, the straightening portion positions the retainer in a direction of approaching the half-inserted terminal fitting or the lance bent by the terminal fitting. The feature is that it has a slope that can be guided. The invention according to claim 3 is the one according to claim 2, wherein the retainer has a locking portion that can be locked with a locked portion of the terminal fitting inserted into the regular depth. As for the surface, the retainer is slanted along the insertion direction of the terminal fitting so that the locked portion of the terminal fitting whose insertion direction front surface is half-inserted can be pushed forward in the insertion direction. It is characterized by having a gradient that causes it.

According to a fourth aspect of the present invention, in the third aspect, the retainer is provided with a pair of arm portions extending in the mounting direction of the retainer with respect to the connector housing at both widthwise end portions. In addition, the connector housing is formed with a pair of groove portions into which the both arm portions can be inserted, and the inclined surface is formed in at least one of the arm portion and the groove portion. Have.

[0007]

<Advantages and effects of the invention><Invention of claim 1> When the retainer is attached to the connector housing after inserting the terminal fitting, the retainer is corrected by the correction section. When the terminal fitting is inserted to the regular depth, the terminal fitting can hold and hold the terminal fitting by the lance and the retainer. On the other hand, when the terminal fitting is held in the half-inserted state, the retainer is straightened by the straightening portion, which interferes with the terminal fitting or the lance bent by the terminal fitting to restrict its mounting. It is possible to reliably detect that the terminal fitting has been half-inserted.

<Invention of Claim 2> Since the correction portion has the inclined surface, the retainer can be smoothly corrected. <Invention of Claim 3> The retainer moves obliquely along the insertion direction of the terminal fitting by the inclined surface of the correction portion. Therefore, when the front surface in the insertion direction of the retaining portion of the retainer in the correction process comes into contact with the locked portion of the terminal fitting that has been half-inserted, the retainer is moved to make the terminal fitting normal. Can be pushed to the depth. Here, if a taper surface for pushing out the terminal fitting is formed in the locking portion, the locking area for the locked portion is reduced by the amount of the tapered surface, whereas according to the present invention. A relatively large locking area of the locking portion can be secured, and the terminal fitting can be firmly prevented from coming off.

<Invention of Claim 4> As the retainer is mounted on the connector housing, both arms are inserted into both grooves, so that the retainer can be prevented from rattling in the width direction, and the mounting work is stable. You can do it.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. In this embodiment, a female connector provided with a so-called side retainer is shown. In this female connector, a female-side terminal fitting 10 can be inserted into a connector housing 20 (hereinafter, simply referred to as a housing 20), and a retainer 40 for retaining the terminal fitting 10 can be attached. . In addition, below, the insertion direction of the terminal fitting 10 with respect to the housing 20 will be described as the front.

The terminal fitting 10 is formed into a shape shown in FIG. 2 by press-molding a metal plate, and has a connecting portion 11 to which a mating male terminal fitting (not shown) can be conductively connected.
A barrel portion 12 crimped to an end of an electric wire W connected to an external circuit is provided in the front and rear. The connecting portion 11 is formed in a substantially box shape, and a pair of elastic tongues 13 capable of elastically contacting the male terminal fitting are provided on the front end side of the connecting portion 11 so as to be opposed to each other. A pair of cantilevered metal lances 14 are formed by cutting and raising from the upper and lower surfaces of the connecting portion 11, both of which are elastically deformable inward. Both metal lances 14 have a cavity 21 at the rear end which is the free end thereof.
It can be locked in the locking grooves 22 formed therein. The stepped portion, which is the rear end portion of the connection portion 11, is a locked portion 15 to which the locking portion 42 of the retainer 40 can be locked.

The housing 20 is made of synthetic resin and, as shown in FIGS. 1 and 2, is entirely formed in a flat block shape and has a cavity 21 into which the terminal fitting 10 can be inserted from the rear. The three chambers are arranged side by side in the width direction. Locking grooves 22 that open to the front are formed on the upper and lower front surfaces of each cavity 21. When the terminal fitting 10 is inserted into the cavities 21 to a normal depth, the locking grooves 2 are formed.
A metal lance 14 can be locked to the rear end surface of the second member 2.
In addition, a lock arm 23 for locking the mating male connector in a fitted state is provided on the upper surface of the housing 20 in a protruding manner.

A retainer 40 can be attached to the housing 20 from below, and a housing structure thereof will be described. A lateral groove portion 24 formed over the entire width of the housing 20 is formed in a substantially central portion of the lower surface of the housing 20 in the longitudinal direction. The lateral groove portion 24 has an opening portion 25 for individually opening each cavity 21 downward. Three are provided side by side. As shown in FIGS. 1 and 3, slits 26 that open downward and forward so as to communicate with the lateral groove portion 24 are cut in the two sidewalls that partition between the adjacent cavities 21, respectively. On both outer sides of the housing 20,
As shown in FIG. 4, a vertical groove portion 27 continuous with the horizontal groove portion 24 is formed to open laterally and downward (direction along the mounting direction of the retainer 40 to the housing 20). The base portion 41 of the retainer 40 can enter the lateral groove portion 24, the locking portion 42 can enter the opening portion 25, the holding arms 44 and 45 can enter the slit 26, and the arm portion 43 can enter the vertical groove portion 27. Since the lateral groove portion 24, the opening portion 25, the slit 26, and the vertical groove portion 27 are formed to have a size with a predetermined clearance with respect to each portion of the retainer 40, the ease of mounting the retainer 40 is secured. ing. In addition, the openings 25 in the upper and lower surfaces of the cavity 21
An insertion groove 28 for allowing the metal lance 14 to pass therethrough without being bent is formed in a rear portion of the rear opening.

The retainer 40 is made of synthetic resin and is shown in FIG.
And, as shown in FIG. 2, a plate-shaped base portion 4 extending in the width direction.
1 and each of the cavities 21 of the base 41
From the position corresponding to the opening 25, three locking portions 42 are provided so as to project upward. Each locking portion 42 is provided in the latter half of the base portion 41 and the locked portion 15 of the terminal fitting 10 is provided.
The front surface that is locked to is a vertically raised end surface. As shown in FIG. 4, a pair of arm portions 43 that can be inserted into the vertical groove portions 27 project upward from both end portions of the base portion 41. From the position between the locking portions 42 of the base portion 41, as shown in FIG.
Holding arms 44 and 45 that can enter the inside are provided so as to project upward in pairs, front and rear. The front and rear holding arms 44 are elastically deformable in a direction in which they approach each other, and locking claws 46 and 47 are provided on the front and rear surfaces of the holding arms 44 in a protruding manner. Then, the retaining claws 46, 47 are respectively retained by the pair of holding protrusions 29, 30 projecting from the front and rear edges of the slit 26, whereby the retainer 40 is attached to the housing 20.
In contrast, it can be held at a temporary locking position and a main locking position having different heights, and can be moved vertically between both positions. It should be noted that both arm portions 43 have respective holding arms 44, 45.
The extension length to the upper side is longer than that.

More specifically, as shown in FIG. 3, the retainer 40 can be held at the temporary locking position by the locking claw 46 of the front holding arm 44 being locked by the front holding projection 29. At this temporary locking position, as shown in FIG. 2, each locking portion 42 is retracted and arranged at a position lower than the cavity 21 by a predetermined height, so that the terminal fitting 10 is moved to the cavity 2
It is permissible to insert and remove with respect to 1. At this time, as shown in FIG. 4, the arm portion 43 has its tip at the vertical groove portion 2
It is arranged at a lower position with an interval of about 1/5 of the entire length of the vertical groove portion 27 from the upper end position of 7, and the outer surface thereof is flush with the outer surface of the housing 20. On the other hand, in the retainer 40, as shown in FIG. 7, the locking claw 47 of the rear side holding arm 45 is locked to the rear side holding projection 30.
It can be held in the main locking position, and in this main locking position, as shown in FIG. 6, each locking portion 42 can protrude into the cavity 21 and lock with the locked portion 15 of the terminal fitting 10. It is said that. At this time, as shown in FIG. 8, the arm portion 43 is arranged at a position where the tip portion thereof is in contact with or close to the upper end of the vertical groove portion 27. Further, the lower surface of the base portion 41 of the retainer 40 is substantially flush with the lower surface of the housing 20.

By the way, the housing 20 and the retainer 40
Since both are made of synthetic resin, it is inevitable that dimensional errors will occur in the product due to the influence of various conditions during molding.
Then, depending on the magnitude of the error, the housing 20
And the clearance between the retainer 40 and
The attached retainer 40 may rattle back and forth. Therefore, the housing 20 is provided with a correction portion 31 so that the retainer 40 can be corrected to a normal position even if such rattling occurs.

As shown in FIG. 8, the straightening portion 31 is disposed in the upper part of the rear end of each of the vertical groove portions 27, is formed in a substantially triangular shape, and gradually protrudes forward as it goes upward. It has an inclined surface 32 with a gentle slope.
The lower end position of the correction portion 31 is set to a position lower by a predetermined dimension than the tip end position of the arm portion 43 when the retainer 40 is in the temporary locking position. Therefore, in the process of mounting the retainer 40 in the temporary locking position, as shown in FIG. 4, at the end of the mounting work, the front and rear edges of the arm portion 43 are brought into sliding contact with the lower end portion of the inclined surface 32 of the correction portion 31. By doing so, the arm portion 43, that is, the retainer 40 is pushed out diagonally forward (oblique direction along the insertion direction of the terminal fitting 10). Then, in the process of moving the retainer 40 from the temporary locking position to the main locking position, as shown in FIG. 8, the tip / rear edge of the arm portion 43 is slidably contacted with the inclined surface 32 of the correction portion 31. By that, retainer 4
0 is pushed further diagonally forward. As a result, the retainer 40 that has reached the main locking position is corrected to a normal position where the front surface of the locking portion 42 comes into contact with or comes close to the front surface of the rim of the opening 25, as shown in FIG. It is like this. The locking portion 42 is capable of interfering with the connecting portion 11 of the terminal fitting 10 that is held in the cavity 21 in a semi-inserted state during the process in which the retainer 40 is corrected to the normal position. Specifically, the rear end portion (locked portion 15) of the connection portion 11 of the terminal fitting 10 is disposed between the front surface of the locking portion 42 and the front surface of the rim of the opening 25 at the temporary locking position. Even in this case, the locking portion 42 surely interferes with the connection portion 11, and the upper surface of the locking portion 42 interferes with the lower surface of the connection portion 11 depending on the front-back position of the connection portion 11 at that time. (See FIG. 9), the front surface (front surface in the insertion direction) of the locking portion 42 interferes with the locked portion 15 (see FIG. 10). In other words, as the retainer 40 is moved along the inclined surface 32 of the correction portion 31, the locking portion 42 is guided in a direction approaching the connection portion 11 of the terminal fitting 10.

In the following, as described above, the housing 20
A description will be given of an assembling process in the case where a clearance between the retainer 40 and the retainer 40 becomes large due to a dimensional error occurring in the retainer 40 and rattling occurs in the retainer 40. To assemble the female connector, first, as shown in FIG. 2, the retainer 40 is attached to the housing 20 at the temporary locking position. At this time, the arm portion 43 is first inserted into the vertical groove portion 27, then the holding arms 44 and 45 are inserted into the slit 26, and the locking portion 42 is inserted into the opening portion 25.
Insert the locking claw 46 of the holding arm 44 on the front side to a depth at which the locking claw 46 locks the holding protrusion 29 (see FIG. 3). Here, the arm portion 43 inserted into the vertical groove portion 27 is pushed forward by a predetermined distance diagonally by the front end rear edge portion slidingly contacting the lower end portion of the inclined surface 32 of the correction portion 31 at the end of the mounting. (See Figure 4). In this process, both arm portions 43 arranged at both ends of the retainer 40 in the width direction are inserted into the vertical groove portions 27 in advance, so that the holding arms 44 and 45 are inserted into the housing 20 before the insertion. The retainer 40 can be positioned in the width direction. Moreover, by inserting the both arm portions 43 into the both vertical groove portions 27, the retainer 40 can be attached to the housing 20 at the temporary locking position without rattling in the width direction. Furthermore, both arm portions 43
Is always exposed to the outside by being inserted into the vertical groove portion 27 formed on the outer surface of the housing 20, so that the mounting state of the retainer 40 can be easily confirmed from the outside by visually checking both arm portions 43. be able to.

Subsequently, the terminal fitting 1 is placed in each cavity 21.
Work to insert 0 from the rear. When the connecting portion 11 that has entered the cavity 21 passes through the opening 25, the two metal lances 14 interfere with the upper and lower surfaces of the cavity 21 and are once deformed. When the terminal fitting 10 is inserted into the cavity 21 to the normal depth, as shown in FIG. 5, the free ends of both metal lances 14 reach the inside of the locking groove 22 and elastically return to the rear end surface of the locking groove 22. Respectively locked to. As a result, the primary locking of the terminal fitting 10 is achieved.

After all the terminal fittings 10 have been inserted, the retainer 40 is pushed into the final locking position. As the retainer 40 is moved to the main locking position, as shown in FIG.
By slidably contacting the inclined surface 32 of No. 1, the arm portion 43 is gradually pushed forward obliquely. And the retainer 40
Reaches the main locking position, and as shown in FIG.
Since the front surface of the locking portion 42 is corrected to a normal position in which it comes into contact with or close to the front surface of the rim of the opening 25, the locking portion 42 protruding into the cavity 21 is against the locked portion 15 of the terminal fitting 10. It is locked with almost no gap. As a result, the terminal fitting 10 is secondarily locked, and the terminal fitting 10 can be held without rattling. In this process, the arm portions 43 of the retainer 40 are inserted deeper into the vertical groove portions 27, so that the retainer 4 is inserted into the housing 20.
The 0 can be mounted in the main locking position without rattling in the width direction.

On the other hand, at the time of inserting the terminal fitting 10, one of the terminal fittings 10 may be stopped in a semi-inserted state before reaching the normal depth, and the metal lance 14 may remain bent. In particular, as shown in FIG. 9, the insertion depth of the terminal fitting 10 is such that the locked portion 15 has the front surface of the locking portion 42 of the retainer 40 before correction (temporary locking position) and the front surface of the rim of the opening 25. If the corrector is not provided as in the conventional case, the retainer can move almost horizontally upward while being displaced rearward from the normal position, so that the locking part is connected. This results in non-interference with the part, resulting in the inability to detect half insertion. On the other hand, in the present embodiment, by providing the correction portion 31, the retainer 40 can be corrected to the regular position in the process of reaching the main locking position. The upper surface of the locking portion 42 abuts against the lower surface of the connecting portion 11 arranged on the path along which the retainer 40 is moved, so that the operation of pushing the retainer 40 to the main locking position is restricted. Therefore, the half-insertion of the terminal fitting 10 can be reliably detected.

Further, the insertion depth of the terminal fitting 10 is deeper than in the state of FIG. 9 described above, and the locked portion 15 is arranged on the path along which the front surface of the locking portion 42 is moved along with the correction. In such a case, as shown in FIG. 10, the front surface of the locking portion 42 is abutted against the locked portion 15 while the retainer 40 is being corrected to the normal position. Then, when the retainer 40 reaches the main locking position and reaches the regular position, the locked portion 15 is pushed forward by the front surface of the locking portion 42, the terminal fitting 10 reaches the regular depth, and the metal The lance 14 elastically returns to be locked in the locking groove 22. That is, the retainer 40 is in the main locking position,
The terminal fitting 10 can be pushed to the normal depth by using the operation of moving it to the normal position.

As described above, according to this embodiment,
Even if the retainer 40 mounted on the housing 20 is rattled back and forth due to a dimensional error between the retainer 40 and the housing 20, the retainer 40 can be moved from the temporary locking position to the main locking position. Along with this, the connecting portion 1 of the terminal fitting 10 in which the retainer 40 is half-inserted by the correction portion 31.
Since it can be corrected to a position that reliably interferes with 1, the half insertion of the terminal fitting 10 can be reliably detected.

Moreover, since the correction portion 31 has the inclined surface 32, the retainer 40 can be smoothly corrected. Further, depending on the insertion depth of the half-inserted terminal fitting 10, the front surface of the locking portion 42 may come into contact with the locked portion 15 during the process in which the retainer 40 is moved while being corrected. . In that case, the retainer 40 is guided by the inclined surface 32 of the correction portion 31 obliquely along the insertion direction of the terminal fitting 10 to utilize the terminal fitting 10.
Can be pushed to the normal depth. Here, if a taper surface for pushing out the terminal fitting is formed on the locking portion, the locking area for the locked portion is reduced by the taper surface. For example, the locking part 4
A relatively large locking area of 2 can be secured, and the terminal fitting 10 can be firmly prevented from coming off. Further, the pair of arm portions 4 are provided along the mounting direction of the retainer 40 with respect to the housing 20 from both ends in the width direction of the retainer 40.
3 is provided so as to extend so that both arm portions 43 are attached to the housing 20.
Since it is inserted into the vertical groove portion 27 provided on the outer side surface of the retainer 40, rattling in the width direction of the retainer 40 can be suppressed, and the mounting work can be stabilized. Moreover, since both arm portions 43 are always exposed to the outside by being inserted into the vertical groove portion 27 formed on the outer surface of the housing 20, the mounting state of the retainer 40 can be checked by visually observing the both arm portions 43. It can be easily confirmed from the outside.

<Modification> In the above-described embodiment, the case where the present invention is applied to the so-called side retainer is illustrated, but the present invention is also applicable to what is called a front retainer. The front retainer is used in a connector that elastically locks the terminal fitting with a resin lance integrally formed in the cavity of the housing, and is attached to the housing along the insertion direction of the terminal fitting. Along with this, a bending restriction portion is provided for restricting the bending deformation of the resin lance locked to the terminal fitting by entering the bending space of the resin lance. That is, the side retainer directly prevents the terminal fitting from coming off, whereas the front retainer indirectly prevents the terminal fitting from coming off. Even in such a connector, if a dimensional error occurs between the front retainer and the housing, the size of the bending space becomes larger than the size of the bending restricting portion, and the terminal metal fitting is partially inserted. Even though the resin lance is still bent, the bending restriction portion may enter the bending space, and the front retainer may be mounted.

Therefore, for example, a correction portion is provided in a main body portion (a portion other than the deflection regulation portion) of the housing or a portion adjacent to the deflection regulation portion in the housing, and the correction portion is provided with the front retainer body portion or the deflection portion. Along with the sliding contact of the restricting portion, the bending restricting portion is formed with an inclined surface that can be corrected in a direction approaching the resin lance (a direction intersecting the insertion direction of the terminal fitting). As a result, when the front retainer is attached when the terminal fitting is half-inserted, the straightening portion corrects the bending restriction portion toward the bent resin lance so that the terminal fitting is half-inserted. The bending restriction portion reliably interferes with the bent resin lance. In this way, the front retainer indirectly (through the resin lance) to the half-inserted terminal fittings
By interfering, the half-insertion of the terminal fitting can be reliably detected. The correction portion may be provided on the front retainer side, or may be provided on both the housing and the front retainer.

<Other Embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition to the above, various modifications can be made without departing from the scope of the invention. (1) In the above-described embodiment, the case where the correction portion is provided on the housing side has been described, but it may be provided on the retainer side. In that case, for example, a protrusion is provided as a correction portion on the rear edge side of the base of the retainer, and the protrusion abuts the rear edge of the opening at the final stage of pushing the retainer into the main locking position, so that the retainer is in the normal position. It should be corrected. Further, the disposition position of the correction section can be appropriately changed according to the specifications of the connector and the like. Note that the correction portion may be provided on both the housing and the retainer.

(2) In the above embodiment, the case where both arm portions are inserted into both vertical groove portions provided on the outer side surface of the housing is shown. However, for example, a bag-like shape in which the vertical groove portions are opened only on the lower surface side of the housing is shown. The present invention also includes a configuration in which both arm portions are inserted therein. With this configuration, it is possible to prevent both arm portions from being opened and deformed in a direction intersecting the insertion direction by the inner peripheral surfaces of both vertical groove portions. (3) In the above-described embodiment, the connector provided with the terminal fitting having the metal lance is shown, but the present invention can be applied to the connector provided with the resin lance integrally formed in the cavity of the housing. (4) In the above-described embodiment, the female connector that accommodates the female-side terminal fitting is shown, but the present invention is also applicable to a male connector that accommodates the male-side terminal fitting. (5) In the above-described embodiment, the cavity has a single-stage type connector, but the present invention is also applicable to a multi-stage connector in which the cavities are stacked in a plurality of stages in the height direction.
