Abstract

PROBLEM TO BE SOLVED: To prevent deformation of a lance. SOLUTION: In a housing 20, cavities 21 allowing the insertion of terminal fittings 10 and retainer mounting holes 26 communicating with the respective cavities 21 are formed by intercrossing them with each other. In a retainer 40, lances 43 elastically deformable along the widthwise direction are formed integrally with it. In relation to the housing 20, the retainer 40 can be held at a tentative lock position allowing a projecting part 48 of each lance 43 to be locked to a stabilizer 14 of the terminal fitting 10 and at a proper lock position allowing almost the whole area of each lance 43 to be locked to a locked part 16 of the terminal fitting 10. A receiving part 44 is formed at a position facing to a flexure permitting space 53A of each lance 43A on the upper tier side within the retainer 40. When the retainer 40 is about to be pushed into the proper lock position with the terminal fitting 10 incompletely inserted and with the lance 43A bent in the permitting space 53A, the lance 43A is received by the receiving part 44, so that the lance 43A is restrained from relatively displacing with respect to a base part 41A.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a connector provided with a lance.

[0002]

2. Description of the Related Art Conventionally, a connector provided with a lance and a retainer for preventing a terminal fitting from coming off has been disclosed in Japanese Unexamined Patent Publication No.
What is described in 325814 is known.
As shown in FIG. 17, a cavity 3 that allows the terminal fitting 2 to be inserted into the connector housing 1 from behind,
A retainer mounting hole 4 in which a retainer 6 can be mounted from below is provided orthogonally to each other, and a lance 5 protrudes from the upper surface in the cavity 3. When the retainer 6 is attached to the connector housing 1 at the temporary locking position and the terminal fitting 2 is inserted into the cavity 3, the lance 5
Is temporarily bent and then returned to be elastically locked at the edge of the locking hole 7 of the terminal fitting 2, whereby the terminal fitting 2 is temporarily held. Thereafter, when the retainer 6 is pushed into the final locking position, the locking portion 8 of the retainer 6 is locked to the jaw 9 of the terminal fitting 2, whereby the terminal fitting 2 is fully locked. By the way, in this connector, since the lance 5 is formed integrally with the connector housing 1, the connector housing 1
It is necessary to protrude a molding pin for molding the lance 5 in a mold for molding the dies, and the shape of the mold tends to be complicated.

In order to simplify the structure of a mold for molding the connector housing, it is conceivable to form a lance on the retainer, which has a relatively simple structure. That is,
The lance is projected forward from the front edge of the retainer, and when the retainer is in the temporary locking position, the terminal fitting is allowed to be inserted into the cavity and the lance is elastically engaged with the inserted terminal fitting. When the retainer reaches the final locking position by being stopped, the final locking is achieved by locking the lance at a deeper position with respect to the terminal fitting.

[0004]

However, when inserting the terminal fittings, if the terminal fittings are held in a half-inserted state before the normal depth, the lances remain in a state of being bent by the terminal fittings. Become. If the retainer is to be pushed into the final locking position in this state, since the lance is restricted from moving by hitting the terminal fitting, the retainer and the lance are relatively displaced, and a problem such as deformation of the lance occurs. There was a fear. The present invention has been completed based on the above circumstances, and has an object to prevent a situation in which a lance is deformed.

[0005]

In order to achieve the above object, according to the present invention, a connector housing is provided with a cavity in which a terminal fitting can be inserted, and is inserted into the cavity. In the connector housing, the terminal fitting can be elastically locked by a lance, wherein the connector housing is provided with a retainer mounting hole to which a retainer in which the lance is integrally formed can be mounted and opened to the side. The retainer allows the terminal fitting to be inserted into the cavity with respect to the connector housing, and the lance can be elastically locked to the terminal fitting that is properly inserted. Between the locking position and a full locking position where the lance can be locked at a deeper position with respect to the terminal fitting, and A receiving portion is provided at a position of the tener facing the bending space of the lance, the receiving portion being capable of controlling relative displacement between the retainer and the lance by receiving the lance bent by the terminal fitting. It is characterized by its structure.

According to a second aspect of the present invention, in the first aspect, the bending direction of the lance is substantially perpendicular to the direction in which the terminal fitting and the lance are inserted into the cavity. However, it has features.

According to a third aspect of the present invention, in the first or second aspect, a plurality of the cavities are arranged in the connector housing, and the receiving portions are adjacent to each other. It has a feature in that it also serves as a partition wall for partitioning each other.

[0008]

<Operation and effect of the invention><Invention of claim 1> When the retainer is arranged in the temporary locking position and the terminal fitting is inserted into the cavity, the lance is once bent by being pressed by the terminal fitting, and the terminal fitting is bent. Is returned when properly inserted, and is elastically locked to the terminal fitting. As a result, the terminal fitting is temporarily held. When the retainer is pushed into the final locking position, the lance is locked at a deeper position with respect to the terminal fitting, thereby achieving the final locking. Here, when inserting the terminal fittings, if the retainer is to be pushed into the final locking position even though the terminal fittings are kept in the half-inserted state, the lance bent by the terminal fittings may be disengaged. Since the lance is arranged to face the receiving portion in the bending space, the lance is received by the receiving portion and is sandwiched between the terminal fittings. Since the relative displacement between the lance and the retainer is thereby restricted, it is possible to prevent the lance from being deformed, and to restrict the movement of the retainer and detect half-insertion of the terminal fitting. .

<Invention of Claim 2> Since the terminal fitting inserted into the cavity, the lance, and the bending space of the lance do not line up in a straight line, it is possible to prevent the connector from being lengthened in one direction. it can.

<Invention of Claim 3> Since the receiving portion also serves as the partition wall, the structure can be simplified as compared with the case where both are provided separately.

From the 41, eight cantilever lances 43 projecting forward are provided at positions corresponding to the respective cavities 21. Retainer 40 with respect to housing 20
As described in detail later, the lance 43 holds the terminal fitting 10 in two positions: a temporary locking position (FIG. 12) where the terminal fitting 10 can be temporarily held, and a full locking position (FIG. 15) where the final locking is possible. And can be moved up and down between the two positions.

As shown in FIGS. 1 and 2, the upper and lower bases 41 are arranged at the same interval as the distance between the lower walls 22A and 22B on the housing 20 side. An extension plate 46 is provided extending from the lower end of the front plate and extending forward and connected to the side plates 42. The upper base 41A, the lower base 41B, and the extension plate 46
The lower lances 43B are connected by a plurality of receiving portions 44 provided so as to individually partition the lances 43B. Receiving part 44
Has a function of partitioning adjacent cavities 21 together with the side wall 27 by being arranged at a position matching the side wall 27 of each cavity 21 and a function of restricting deformation of the upper-side lance 43A as described in detail later. are doing. Both bases 41
At the position on the front side in FIG. 2 (right side in FIG. 3) of the upper surface of the lance 43, an insertion recess 45 through which the stabilizer 14 can be inserted is formed to open frontward and rearward. The depth of the insertion recess 45 is about half the thickness of the base 41.

The lance 43 has an arm portion 47 having the same thickness as the base portion 41 and extending in the front-rear direction.
And, as shown in FIG. 3, a projection 48 of the arm portion 47 projecting from the right side surface in FIG. The arm portion 47 can be bent and deformed in the width direction (direction substantially orthogonal to the direction in which the terminal fittings 10 inserted into the cavity 21 and the lances 43 are arranged), and is arranged on the left side in FIG. It is retracted into the flexure allowable space 53. As shown in FIG. 1, the protrusion 48 is provided in the upper half height area of the right side surface of the arm 47 in the drawing, and is disposed in front of the insertion recess 45. This lance 4
As shown in FIG. 2, the front surface of the projection 3 projects forward from the upper end to the lower end, and extends forward from the arm 47 to the projection 48 as shown in FIG. 3. It is formed in a tapered shape.

As shown in FIG. 2, the side plates 42 are
1 is formed in a plate shape projecting forward, rearward and upward from above, and cantilevered holding arms 49 that can be elastically deformed in the front-rear direction by inserting a pair of vertical slits in the upper part of both side plates 42. , 50 are formed in pairs at the front and rear. The front and rear holding arms 49 and 50 are provided with holding projections 51 and 52 projecting forward and backward, respectively, and the both holding projections 51 and 52 are provided on the holding projection 2 on the housing 20 side.
The retainer 40 is held at the provisionally locked position or the fully locked position by being locked to 8, 29.

That is, the upper surface of the front held projection 51 abuts against the lower surface of the holding projection 28, and the lower surface of the rear held projection 52 is engaged with the upper surface of the holding projection 29, as shown in FIG. As shown, the lower end of the retainer 40 has the housing 2.
It is held at a temporary locking position protruding downward from zero. In this temporary locking position, the base 41 and the lance 43 are
The terminal fitting 10 is allowed to be inserted into the cavity 21 by being arranged at the same height position as the lower wall 22 and the insertion recess 45 being aligned with the insertion groove 23.
The protrusion 48 of the lance 43 is provided with the insertion groove 23 and the insertion recess 45.
Are arranged on the passage path of the stabilizer 14 through which is inserted. As shown in FIG. 6, the rear surface of the protrusion 48 is formed in a tapered shape that forms an obtuse angle with respect to the side surface of the arm portion 47.
The arm portion 47 can be guided so as to be elastically deformed by pressing the stabilizer 14 from behind (see FIG. 10). The deflection allowance of the lance 43 at this time is substantially the same as the width of the stabilizer 14. On the front surface of the projection 48, the rear surface of the stabilizer 14 of the terminal fitting 10 inserted into the cavity 21 to the normal depth can be locked (see FIG. 13).

When the retainer 40 is pushed upward from the temporary locking position, the holding projection 51 on the front side passes over the holding projection 28 and the holding arm 49 is once elastically deformed, and the retainer 40 is moved to the full locking position. When it reaches, the holding arm 49 elastically returns, and the lower surface of the held projection 51 becomes the holding projection 2.
8 is locked to the upper surface. As a result, the retainer 40 is held at the final locking position where the lower surface thereof is flush with the lower surface of the housing 20, as shown in FIG. In this final locking position, the lance 43 protrudes into the cavity 21 and enters the escape recess 15 of the terminal fitting 10,
The front surface of the lance 43 is locked by the locked portion 16 of the main body 11. The locked portion 16 is formed by the two projecting pieces 11 of the main body 11.
c, 11d and a part of both side walls 11b, and is locked over substantially the entire front surface of the lance 43. (See FIG. 8).

Here, differences between the upper and lower lances 43 will be described. In the upper lance 43A, as shown in FIG. 1, a deflection allowable space 53A for allowing the deflection and deformation is disposed between the lance 43A and the left adjacent lance 43A. The parts 44 are arranged to face each other. The upper surface of the receiving portion 44 and the lower surface of the lance 43A are flush. Therefore, as shown in FIG. 11, when the lance 43A is bent and deformed during the insertion of the terminal fitting 10, a part of the arm portion 47 is disposed between the side wall 27A of the upper cavity 21A and the receiving portion 44. You will enter. If the retainer 40 is pushed upward in this state, the bent lance 43A is sandwiched between the side wall 27A and the terminal fitting 10 and the receiving portion 44, so that the lance 43A and the base 41A are relatively displaced, The deformation of the lance 43A in the height direction can be restricted.
As shown in FIG. 15, when the retainer 40 reaches the final locking position, the upper side wall 27 </ b> A
Is closed by entering, so that the bending of the lance 43A in the width direction is restricted. The arm 47
As shown in FIG. 6A, a tapered release guide surface 54 is formed on the lower right side surface of FIG. As shown in FIG. 4, the release guide surface 54 faces the release hole 30 when the retainer 40 is assembled at the temporary locking position, and is released from the front through the release hole 30 (see FIG. 4). (Not shown), the arm 4
7 can be guided so as to be elastically deformed.

As shown in FIG. 6 (B), the lower end of the lance 43B is formed such that the front end of the arm portion 47 in the drawing is cut off in a tapered shape to a predetermined depth, so that a receiving portion adjacent to the front side is formed. 44 and a flexure allowable space 53B is secured. As shown in FIG. 1, an extension plate 46 is arranged below the lance 43B so as to face a predetermined height. Therefore, as shown in FIG. 11, if the retainer 40 is to be pushed into the final locking position in a state where the lance 43 </ b> B is bent (a state in which the terminal fitting 10 is partially inserted), the extension plate 46 is used. The lance 43B is engaged with the lance 43B.
Can be restricted from being excessively deformed in the height direction. In addition, a release jig (not shown) for operating the lance 43B from below is inserted into the extension plate 46 at a position below the protrusion 48 of the lance 43B, as shown in FIGS. A possible release groove 55 is cut out.

This embodiment has the above-described structure, and its operation will be described below. First, the housing 20
The retainer 40 is inserted from below into the retainer mounting hole 26, and is mounted at the temporary locking position as shown in FIG.
In this temporary locking position, the base 41 and the lance 43 are accommodated within the thickness of the lower wall 22 of the cavity 21 and the insertion recess 45 is aligned with the insertion groove 23 so that the terminal fitting 10 can be inserted. As shown in FIG. 7, the allowable deformation space 53 of each lance 43 is ensured, so that the lance 43 is allowed to bend and deform.

The terminal fitting 1 is inserted into each cavity 21 from behind.
When 0 is inserted, the stabilizer 14 is brought into sliding contact with the peripheral surfaces of the insertion groove 23 and the insertion concave portion 45, thereby guiding the insertion operation. When the terminal fitting 10 is inserted to a predetermined depth, the protrusion 4 of the lance 43 protrudes forward of the insertion recess 45.
8, the front surface of the stabilizer 14 is engaged, and as shown in FIGS. 9 and 10, the arm portion 47 is bent along the width direction while being guided by the taper of the projection 48 as the insertion proceeds further. Then, as shown in FIG. 11, it retreats into the left bending allowable space 53. When the terminal fitting 10 is inserted to the normal depth, as shown in FIGS. 12, 13 and 14, the stabilizer 14 reaches the front of the projection 48, the arm 47 returns elastically, and the front of the projection 48 By locking the rear surface of the stabilizer 14, the terminal fitting 1
0 is elastically locked and is temporarily held.

After all the terminal fittings 10 have been inserted,
The retainer 40 is pushed upward to move to the final locking position. Then, as shown in FIG. 15, the base 41 and the lance 43 protrude into the cavity 21, and the lance 43 enters the escape recess 15 of the terminal fitting 10, so that the front surface of the lance 43 extends over substantially the entire body portion. 11
Is locked by the locked portion 16. Thereby, the terminal fitting 1
Zero final locking is achieved. At this time, as shown in FIG. 16, the deflection allowable space 53A of the upper lance 43A is closed by the entrance of the side wall 27A of the upper cavity 21A, and the lance 43A is bent and deformed in the width direction. Is regulated.

When the terminal fitting 10 is inserted, the terminal fitting 10 may be kept in a half-inserted state before reaching the normal depth, and the lance 43 may be left bent. Despite the presence of the terminal fitting 10 in such a half-inserted state, the worker may mistakenly think that the insertion has been performed properly and try to push the retainer 40 to the final locking position. For example, as shown in FIG. 10 (A), when the upper terminal fitting 10 is in a half-inserted state, as shown in FIG. 11, the arm portion 47 of the lance 43A bent into the bending allowable space 53A, Receiving part 44 and upper stage cavity 21A
And between the side walls 27A. Therefore, retainer 4
When 0 is pushed upward, the arm portion 47 is received by the receiving portion 44 and is sandwiched between the side wall 27A and the terminal fitting 10, so that the relative displacement of the lance 43A and the base portion 41A is restricted. This prevents the lance 43A from being deformed in the height direction. This restricts the movement of the retainer 40 to the final locking position.
It is detected that 0 is half-inserted. Meanwhile, FIG.
As shown in FIG. 0 (B), when the lower terminal fitting 10 is in the half-inserted state, as shown in FIG. 11, a predetermined space is provided below the lance 43B bent into the bending allowable space 53B. Since the extension plate 46 is arranged in an empty state, the retainer 4
0 is pushed upward, the arm 4 of the lance 43B
Reference numeral 7 denotes a base part 4 which is in contact with a terminal fitting 10 arranged above.
Although slightly bent downward with respect to 1B, further deformation (relative displacement with respect to the base 41B) is restricted by engaging with the extension plate 46. This restricts the movement of the retainer 40 to the final locking position, and detects that the terminal fitting 10 has been half-inserted.

On the other hand, the terminal fitting 10 may be removed from the housing 20 depending on circumstances such as maintenance.
In this case, as shown in FIG. 12, after returning the retainer 40 from the final locking position to the temporary locking position, the terminal fitting 10 is pulled out of the cavity 21 while operating each lance 43 with a predetermined release jig. To Upper lance 43
A can be operated by pressing the release hole 3 from the front of the housing 20.
Insert the release jig into 0. Since the release guide surface 54 of the lance 43A is disposed behind the release hole 30 (see FIG. 4), the release guide surface 54 is pressed by inserting the release jig straight along the release hole 30. Thus, the lance 43A is bent until the locked state between the stabilizer 14 and the projection 48 is released (see FIG. 13A). On the other hand, in order to operate the lower lance 43B, a release jig is inserted into the release groove 55 of the extension plate 46 from below the housing 20 as shown in FIG.
By pressing the front side surface of FIG. 2, the lance 43B is caused to bend until the locked state between the stabilizer 14 and the projection 48 is released (see FIG. 13B).

As described above, according to the present embodiment,
Allowable space 5 for upper lance 43A in retainer 40
Since the receiving portion 44 facing the 3A is provided, the bent lance 43A is received by the receiving portion 44 even if the retainer 40 is pushed into the final locking position when the terminal fitting 10 is in the half-inserted state. By being sandwiched between the side wall 22A of the upper cavity 21A and the inserted terminal fitting 10, the relative displacement of the lance 43A and the retainer 40 can be restricted, and the lance 43A is deformed. Such a situation can be prevented, and the half insertion of the terminal fitting 10 can be detected by restricting the movement of the retainer 40. The lower lance 43B is similarly received by the extension plate 46 to prevent deformation.

Further, since the bending direction of the lance 43 is perpendicular to the direction in which the terminal fitting 10 inserted into the cavity 21 and the lance 43 are aligned, the cavity 2
The terminal fitting 10, the lance 43, and the deflection allowable space 53 inserted into the connector 1 do not line up in a straight line, so that it is possible to prevent the connector from being lengthened in one direction.

Further, since the receiving portion 44 has a function of partitioning the adjacent cavities 21, the structure can be simplified as compared with a case where a partition wall is separately provided.

<Other Embodiments> The present invention is not limited to the embodiments described above with reference to the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition, various changes can be made without departing from the scope of the invention. (1) In the above embodiment, the lance bends along the width direction. However, the present invention can be applied to a lance that bends along a height direction orthogonal to the width direction.

(2) In the above embodiment, the case where the receiving portion has the function of partitioning the adjacent cavities has been described. However, the receiving portion has only the function of receiving the lance, and a separate partition wall is provided. Such may be included in the present invention. (3) In the above-described embodiment, the one in which the protrusion of the lance is locked to the stabilizer having a function of guiding the insertion operation of the terminal fitting, but the portion where the lance is locked is a portion other than the stabilizer. Is also good.

(4) In the above embodiment, the connector having the upper and lower cavities has been described.
The present invention includes those having more than one cavity or those having only one cavity. In particular, in the case of a one-stage type, the retainer may be mounted on the housing after the terminal fitting is inserted into the cavity. (5) In the above-described embodiment, the female connector having the crimping type terminal fitting is shown. However, the type of the terminal fitting may be a type for crimping the core wire of the electric wire. The invention is applicable.
