Abstract

PURPOSE: To position the leg part of a male terminal metal fitting at a low cost, efficiently, and without detracting alignment. CONSTITUTION: Accompanied with the insertion of a connecting part 32A into a through hole 34, a leg part 32B is moved in parallel to fit a protrusion piece 36 into a fitting hole 35. Since the protrusion piece 36 and the fitting hole 35 are faced so as to be fitted in a direction same as the through direction of the connecting part 32A, in a fitting work, it is eliminated that the protrusion piece 36 interferes with a housing 31 or the other member, etc., to bendingly deform a male terminal metal fitting 32. Consequently, the protrusion piece 36 and the fitting hole 35 are surely and rightly fitted to eliminate the detraction of the alignment of the leg part 32B. The protrusion piece 36 and the fitting hole 35, a positioning means 33, are formed on the leg part 32B and the housing 31, thereby reducing a cost. Since the male terminal metal fitting 32 can be separately mounted one by one, thereby facilitating the fitting of the protrusion piece 36 and the fitting hole 35.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board connector for preventing misalignment of terminal fittings.

[0002]

2. Description of the Related Art A board connector comprises a housing having a hood portion and an L-shaped bent male terminal fitting, and a connecting portion of the male terminal fitting connected to the female terminal fitting is inserted into the housing by press fitting. The tip side is projected into the hood portion, and the leg portion connected to the substrate is exposed on the side opposite to the hood portion of the housing. In such a board connector, since the connection portion of the male terminal fitting is in the hood portion, it is protected from interference with other members. On the other hand, since the leg portion is exposed on the side opposite to the hood portion of the housing, there is a possibility that the leg portion may be bent or tilted due to contact with another member to cause misalignment. Therefore, a positioning means is provided to prevent the misalignment of the legs.

As an example of the positioning means, Japanese Patent Application Laid-Open No. 6-62
There is one disclosed in Japanese Patent Laid-Open No. 3-128575.
This is the housing 2 as shown in FIGS.
A plurality of protruding pieces 22 are integrally formed on the surface of the male terminal fitting 21 on the side where the leg portions 21a are exposed so as to be located between the adjacent leg portions 21a, 21a, and the lower surface of each protruding piece 22 is formed. A sloped surface 22a and a recessed portion 22b are formed in
A projecting portion 21b that fits into the concave portion 22b is formed on the side edge of a. The male terminal fitting 21 is attached by inserting the connecting portion 21c into the through hole 23 of the housing 2 in a state that the male terminal fitting 21 is bent and formed in advance. This connection 2
With the insertion of 1c, the leg portion 21a is fitted between the projecting pieces 22 and 22, and the projecting portion 21b is in contact with the lower surface of the projecting piece 22 as shown in FIG. The protrusion 21b is moved to the slope 22a as shown in FIG. 13 (b).
After the connecting portion 21c is inserted to a predetermined position after getting over the ridge, as shown in FIG.
Reaches a state of being fitted into the recess 22b. In this state, the bending or tilting of the leg portions 21a is prevented by the engagement between the protrusions 21b and the concave portions 22b, and thus each leg portion 21a is positioned.

[0004]

SUMMARY OF THE INVENTION In the above means,
When the male terminal fitting 21 is mounted, the connecting portion 21c is held in the through hole 23 so that it cannot move up and down. Therefore, due to the frictional resistance generated between the protrusion 21b and the inclined surface 22a, the male terminal fitting 21 is prevented.
Elastically deforms so as to expand at its bent portion, and in that state, the leg 21a moves along the slope 22a so as to follow the insertion movement of the connecting portion 21c, and then the protrusion 21b is elastically restored by the elastic restoring force. It is adapted to fit in the recess 22b.

For this reason, when the protrusion 21b moves on the slope 22a, the burr remaining on the protrusion 21b is removed by the slope 22a.
It may be caught in the
If the frictional resistance between b and the slope 22a becomes abnormally large, the legs 21a cannot smoothly follow the movement of the connecting portion 21c, and the male terminal fitting 21 deforms excessively beyond its elastic limit, resulting in plasticity. Deformation may occur.

In this case, the male terminal fitting 21 is not restored to its original shape, and the projection 21b is not fitted into the recess 22b even though the connecting portion 21c has reached the predetermined mounting position. Even if the protrusion 21b fits into the recess 22b, the leg 21a is tilted with respect to the normal direction, and the alignment of the leg 21a is disturbed in any state. As described above, the conventional means has a problem in that the alignment may be misaligned at the stage of mounting the male terminal fitting.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to reliably prevent misalignment of the legs of the terminal fittings.

[0008]

According to a first aspect of the present invention, an L-shaped male terminal fitting including a connecting portion connected to a female terminal fitting and a leg portion connected to a board penetrates the connecting portion into a housing. In the board connector mounted in a state in which the leg portion is exposed to the side opposite to the hood portion of the housing, the connector is formed so as to face the housing and the leg portion. It is configured to include a fitting portion that fits in the same direction as the penetrating direction, and a positioning means that holds the leg portion immovably with respect to the housing by fitting both fitting portions.

According to a second aspect of the present invention, in the first aspect of the invention, the positioning means includes a fitting hole formed in the housing and a projecting piece formed in the leg, and the projecting piece is press-fitted into the fitting hole. The leg parts are fixed to the housing by.

According to a third aspect of the present invention, in the first aspect of the invention, the positioning means includes a fitting protrusion formed on the housing and a fitting hole formed on the leg portion, and the fitting protrusion is press-fitted into the fitting hole. By doing so, the legs are fixed to the housing.

According to a fourth aspect of the present invention, in the third aspect of the present invention, the fitting projection penetrates through the fitting hole and is fitted, and by crimping the penetrating tip, the leg portion is retained in the housing. The configuration is fixed.

[0012]

According to the present invention, when the connecting portion of the male terminal fitting is penetrated into the housing and the leg portion moves in parallel with the housing and approaches the housing, the fitting portion of the leg portion fits into the housing. Fit to the part. At this time, since both fitting parts are provided so as to face each other so as to fit in the same direction as the penetrating direction of the connection part, the fitting part does not interfere with the mating part on the other side or other members. As a result, the male terminal fitting does not flex and deform. When the male terminal fittings are attached to the housing, the legs are prevented from moving with respect to the housing due to the fitting force of both fitting parts, so they can be displaced or tilted even if pressed by other members. No, the leg alignment is retained.

According to the second aspect of the present invention, the projecting piece of the male terminal fitting and the fitting hole of the housing are provided so as to face each other so as to be fitted in the same direction as the penetrating direction of the connecting portion. Does not interfere with the housing or other members to cause the male terminal fitting to bend and deform. In the state where the male terminal fitting is mounted on the housing, the alignment force of the leg is maintained by the fitting force between the projecting piece and the fitting hole.

According to the invention of claim 3, the fitting hole of the male terminal fitting and the fitting projection of the housing are provided so as to face each other so as to be fitted in the same direction as the penetrating direction of the connecting portion. There is no possibility that the portion interferes with the housing or other members and the male terminal fitting is bent and deformed. In the state where the male terminal fitting is mounted on the housing, the alignment of the legs is maintained by the fitting force between the fitting hole and the fitting protrusion.

In the invention of claim 4, the fitting hole of the leg portion and the fitting protrusion of the housing are fitted in a state in which the fitting protrusion penetrates the fitting hole. From this state, by caulking the tip that penetrates the fitting hole of the fitting protrusion,
The fitting protrusion is prevented from coming off from the fitting hole, and the leg portion is fixed to the housing in a non-movable manner.

[0016]

According to the inventions of claims 1 to 3,
The fitting portion of the housing and the fitting portion of the leg portion can be fitted together without causing bending deformation of the male terminal fitting, so that the male terminal fitting does not bend excessively beyond its elastic limit. There is no risk that both fitting parts will not fit and the legs will be in an inclined posture, thereby preventing the leg alignment from being misaligned in the fitting process of the fitting parts. There is an effect that can be.

According to the fourth aspect of the present invention, since the legs are fixed to the housing by crimping the tips of the fitting protrusions, compared with the case where the fitting protrusions and the fitting holes are simply fitted together. With this, there is no possibility that the fitting hole and the fitting projection will be disengaged, and there is an effect that it is possible to more reliably prevent the alignment of the legs from being misaligned when the male terminal fitting is mounted on the housing.

The through hole 34 is for holding the male terminal fitting 32 by penetrating it from the rear side (the side opposite to the hood portion 31B), and its penetrating direction is perpendicular to the rear surface of the housing main body portion 31A. It has a horizontal front-back orientation. A block portion 31C for holding the male terminal fitting 32 is provided below the through hole 34 of the housing body portion 31A.
Are integrally formed to project from the rear surface of the housing body 31A. On the rear surface of the block portion 31C, a plurality of fitting holes 35 corresponding to the through holes 34 are formed side by side in a row at the same pitch as the through holes 34. The fitting hole 35 has a narrow width in the left-right direction and is formed so as to have an elongated cross-sectional shape in the vertical direction, and the vertical dimension thereof has a taper shape that gradually narrows toward the back side (front side). There is.

The male terminal fitting 32 is formed by punching a conductive thin metal plate into a predetermined elongated shape and bending it so as to form an L shape as a whole. The male terminal fitting 32 extends forward in the horizontal direction and is not shown in the drawing. Connection part 32A fitted to
And a leg portion 32B that extends downward and is fitted into the insertion hole H of the printed circuit board P. The male terminal fitting 32 is mounted by press-fitting the connecting portion 32A into the through hole 34 from the rear of the housing 31. In the mounted state, the male terminal fitting 32 is held in a fixed posture by the pressure input to the through hole 34 of the connecting portion 32A, the connecting portion 32A has its tip portion projected into the hood portion 31B, and the leg portion 32B is the housing. It is exposed to the rear of 31 and contacts the rear surface of the block portion 31C.

At a position corresponding to the height of the block portion 31C of the leg portion 32B, a projecting piece 36 projecting forward from the left side edge is integrally formed. The projecting piece 36 has a taper shape in which the vertical width gradually decreases toward the front, and when the male terminal fitting 32 is attached to the housing 31, the protruding piece 36 is press-fitted into the fitting hole 35 of the block portion 31C. It is supposed to be done. This housing 31
The fitting hole 35 and the projecting piece 36 of the male terminal fitting 32 constitute the positioning means 33 of the present invention.

Next, the operation of this embodiment will be described. When the male terminal fitting 32 is attached to the housing 31, the connecting portion 32A is press-fitted into the through hole 34 from the rear of the housing 31, so that the leg portion 32B and the protruding piece 36 together with the housing 3
1, and the leg portion 32B moves in parallel to the block portion 31.
When approaching the rear surface of C to a certain distance, the projecting piece 36 starts to enter the fitting hole 35. And the connecting portion 32A
Is pressed into the normal position, the protrusion 36
Is pressed into the fitting hole 35 so that
The leg portion 32B contacts the block portion 31C. As described above, the mounting work of the male terminal fitting 32 to the housing 31 and the fitting work of the projecting piece 36 and the fitting hole 35 are completed (see FIG. 2).

In the work of fitting the projecting piece 36 into the fitting hole 35, the projecting piece 36 and the fitting hole 35 are formed so as to face each other without interposing another member therebetween, and The piece 36 and the fitting hole 35 are fitted together by approaching in the same direction as the penetrating direction of the connecting portion 32A into the through hole 34. Therefore, when the projecting piece 36 is fitted into the fitting hole 35, it does not interfere with or get caught in the housing 31 and other members. Therefore, due to the interference and the catching of the projecting piece 36. There is no possibility that the male terminal fitting 32 will not return to its original shape as a result of excessive bending beyond the elastic limit. Therefore, the fitting of the protruding piece 36 into the fitting hole 35 is surely performed, and the leg portion 32B is kept in a correct posture at the time of fitting,
There is no risk of misalignment.

In the state where the male terminal fitting 32 is mounted and the projecting piece 36 and the fitting hole 35 are fitted, the connecting portion 32A is fixed immovably by the pressure input to the through hole 34, and thus the connecting portion is formed. The 32A alignment is retained. on the other hand,
The leg portion 32B is prevented from moving in any of the front-rear direction, the left-right direction, and the up-down direction by a pressure input to the fitting hole 35 of the protruding piece 36. Therefore, the leg portion 32 may be touched by the operator's hand or contacted with other members during transportation or work.
Even if the pressing force acts on B, the alignment of the leg portion 32B is maintained.

As described above, the connector 30 of this embodiment
Does not cause misalignment in the alignment of the leg portions 32B both during the mounting work of the male terminal fitting 32 and after the mounting. Therefore, when the connector 30 is attached to the printed circuit board P, the leg portion 32 is inserted into the insertion hole H.
When the lower end of B is fitted, the lower ends of all the leg portions 32B are accurately aligned with the arrangement of the insertion holes H.
The fitting work can be easily performed.

Further, in the connector 30 of this embodiment, the positioning means 3 for holding the alignment of the leg portions 32B.
Since the projecting piece 36 and the fitting hole 35 that form part 3 are integrally formed with the male terminal fitting 32 and the housing 31, respectively, a component separate from the male terminal fitting 32 and the housing 31 is used as the positioning means. Compared with the case where it is used, it is not necessary to manufacture, transport, or store the separate parts, so that the cost can be kept low.

Moreover, the work of positioning the leg portion 32B by fitting the projecting piece 36 and the fitting hole 35 is performed by the male terminal fitting 32.
Since it is performed at the same time as the work of mounting the device in the housing 31, the number of steps is small and the work efficiency is high.

Further, the positioning work can be carried out individually for each male terminal fitting 32, not for all the male terminal fittings 32 at once. Even if the position is displaced vertically and horizontally, it is easy to correct the displacement, and the protrusion 36 can be fitted into the fitting hole 35 efficiently and reliably.

In this embodiment, the upper and lower edges of the projecting piece 36 and the upper and lower inner surfaces of the fitting hole 35 are tapered so as to be narrowed forward. Therefore, when the connecting portion 32A is penetrated into the through hole 34, the male portion is penetrated. Even if the posture of the terminal fitting 32 is tilted in the vertical direction, the tip of the projecting piece 36 can surely enter the opening of the fitting hole 35 without hitting the rear surface of the block portion 31C.

In the above description, the male terminal fitting 32 is preliminarily bent into an L-shape and mounted on the housing 31, and at the same time when the male terminal fitting 32 is mounted, the projecting piece 3 is attached.
6 is fitted in the fitting hole 35, the assembling is carried out, but the same positioning means 33 as in the present embodiment.
When the above is provided, the assembly can be performed by a procedure different from the above description. That is, the male terminal fitting 32 is the protruding piece 3
By bending and molding only 6, the connecting portion 32A and the leg portion 3
2B and a temporary molding state in which they are aligned with each other, and press fitting into the through hole 34 is performed in this state. After that, the leg 32B is formed by bending the male terminal fitting 32 downward.
At the same time that the protrusions 36 are formed, the protrusions 36 are fitted into the fitting holes 35. At this time, the projecting piece 36 approaches the fitting hole 35 so as to draw an arc, but immediately before the projecting piece 36 is fitted into the fitting hole 35, the projecting piece 36 has a posture in which the projecting piece 36 faces in the front-rear direction. Moreover, since the upper and lower edges of the projecting piece 36 are tapered, the projecting piece 36 smoothly fits into the fitting hole 35 without hitting the rear surface of the block portion 31C. Even with such a procedure, the protrusion 36 does not interfere with or get caught in the housing 31 or other members.
Since B is held in the correct posture, there is no fear that the alignment of the leg portion 32B is disturbed.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG.

In the male terminal fitting 42 of this embodiment, the plate material is approximately L.
It is formed by punching into a letter shape without bending, and its plate surface faces at a right angle to the rear surface of the housing (not shown). In the leg portion 42B of the male terminal fitting 42,
A wedge-shaped protrusion 46 is formed by extending the plate surface so that the plate surface is flush with the plate surface of the leg portion 42B.

The housing in which the male terminal fitting 42 is mounted is provided with a vertically elongated through hole (not shown) into which the connecting portion 42A is press-fitted, and at the position directly below each through hole, respectively. A vertically elongated narrow fitting hole (not shown) into which the protruding piece 46 is press-fitted is formed.

Also in this embodiment, as in the first embodiment,
The projecting piece 46 and the fitting hole face each other without interposing another member therebetween, and the fitting direction of the projecting piece 46 and the fitting hole is the same as the penetrating direction of the connecting portion 42A into the through hole. There is. Therefore, the male terminal fitting 42 is not deformed due to the interference of the projecting piece 46 with the housing and other members when the projecting piece 46 is fitted into the fitting hole, and the projecting piece 46 is fitted into the fitting hole. Is performed securely, and the leg portion 42B at the time of fitting
Is kept in the correct posture and there is no risk of misalignment. Even after the male terminal fitting 42 is mounted, the protruding piece 4
Alignment of the leg portion 42B is ensured by the pressure input between 6 and the fitting hole.

Further, the male terminal fitting 42 of the present embodiment is formed by punching the plate material without completing the bending process, so that the number of manufacturing steps is small, the manufacturing efficiency is high, and the manufacturing cost is high. Is kept low.

<Third Embodiment> Next, a third embodiment of the present invention will be described with reference to FIGS. The board connector 50 according to this embodiment includes a housing 51 and a male terminal fitting 5.
And a positioning means 53 formed on the housing 51 and the male terminal fitting 52.

The housing 51 has a housing body 51.
A and a hood portion 51B protruding forward from the housing main body portion 51A. The housing body 51A includes a rear end surface of the hood 51B and the housing body 5
A plurality of through-holes 54 that open to the rear surface of 1A are formed side by side in a row at the same height, and the penetrating direction is at right angles to the rear surface of the housing body 51A and is a horizontal front-back direction. . Below the through holes 54 on the rear surface of the housing body 51A, a plurality of fitting projections 55 corresponding to the through holes 54 are provided in a row in the same pitch as the through holes 54. The fitting protrusion 55 is formed by protruding further rearward from the protruding end surface of the boss 51C protruding from the housing body 51A into a columnar shape having a step and a small diameter, and the protruding direction of the fitting protrusion 55 is a male terminal. The connection portion 52A of the metal fitting 52 is in the same direction as the direction in which it is fitted into the through hole 54. The protruding end surface of the boss 51C serves as a stopper with which the front surface of the leg portion 52B of the male terminal fitting 52 abuts.

The male terminal fitting 52 is formed by punching a thin metal plate into an elongated predetermined shape and bending it so as to form an L-shape as a whole, and extends forward in the horizontal direction to fit into a female terminal fitting (not shown). And a leg portion 52B that extends downward and is fitted into the insertion hole H of the printed circuit board P. The male terminal fitting 52 is mounted by press-fitting the connecting portion 52A into the through hole 54 from the rear of the housing 51. Male terminal fitting 5 when mounted
2 is held in a fixed posture by the pressure input to the through hole 54 of the connecting portion 52A, the connecting portion 52A has its tip portion projected into the hood portion 51B, and the leg portion 52B is exposed to the rear of the housing 51 and blocked. It contacts the rear surface of the portion 31C.

At a position corresponding to the fitting protrusion 55 of the leg portion 52B, a fitting hole 56 penetrating from the front surface to the rear surface of the leg portion 52B.
Are formed. The fitting hole 56 is formed in the male terminal fitting 52.
With the fitting projection 55 attached to the housing 51.
Are fitted in a penetrating state. The fitting protrusion 55 of the housing 51 and the fitting hole 56 of the male terminal fitting 52
The above constitutes the positioning means 53 of the present invention.

Next, the operation of this embodiment will be described. When the connecting portion 52A of the male terminal fitting 52 is pressed into the through hole 54 from the rear of the housing 51, the leg portion 52B moves toward the housing 51 in parallel while approaching the rear surface of the housing 51, and the fitting protrusion 55 is formed. It passes through the fitting hole 56. Then, as soon as the connecting portion 52A reaches the predetermined mounting position, the front surface of the leg portion 52B abuts on the stopper surface of the boss 51C. From this state, the tip end portion of the fitting projection 55 protruding rearward of the fitting hole 56 is caulked by a jig (not shown) to be plastically deformed. As a result, the fitting projection 55 is deformed so as to expand in the fitting hole 56, the outer circumference of the fitting projection 55 and the inner circumference of the fitting hole 56 are closely attached to each other, and the fitting projection 55 is fitted without rattling. The portion thus formed becomes a caulking head portion 55A and spreads around the hole edge of the fitting hole 56 in a brim-like manner to be in close contact, and the leg portion 52B is sandwiched between the caulking head portion 55A and the stopper surface of the boss 51C. (See FIG. 7).

As described above, the work of mounting the male terminal fitting 52 in the housing 51 and the work of fitting the fitting projection 55 and the fitting hole 56 are completed. After that, the housing 51 is fixed to the printed circuit board P, and the leg portions 52B are fitted into the insertion holes H (see FIG. 8).

In the work of fitting the fitting protrusion 55 and the fitting hole 56, the fitting protrusion 55 and the fitting hole 56 are formed so as to face each other without interposing another member therebetween. The fitting protrusion 55 and the fitting hole 56 are fitted by approaching in the same direction as the penetrating direction of the connecting portion 52A into the through hole 54. For this reason,
When the fitting protrusion 55 and the fitting hole 56 are fitted, the leg portion 52B
Does not interfere with or get caught in the housing 51 and other members. Therefore, the male terminal fitting 52 is excessively bent beyond the elastic limit due to the interference and catching of the leg portion 52B, and the original shape is restored. There is no fear that it will not happen. Therefore, the fitting projection 55 and the fitting hole 56 are securely fitted to each other, the leg portion 52B is kept in the correct posture at the time of fitting, and the leg portion 52B is not likely to be misaligned.

Further, in the state where the male terminal fitting 52 is mounted and the fitting projection 55 and the fitting hole 56 are fitted, the connecting portion 5
2A is immovably fixed by the pressure input to the through hole 54, and thus the alignment of the connecting portion 52A is maintained. On the other hand, the leg portion 52B is prevented from moving in any of the front-rear, left-right, and up-down directions by the fitting force between the fitting protrusion 55 and the fitting hole 56 and the holding force by the crimping head 55A and the boss 51C. It is fixed to. Therefore, the alignment of the leg portions 52B is maintained even when the pressing force acts on the leg portions 52B due to the operator's hand touching or other members coming into contact during transportation or work.

As described above, the connector 50 of this embodiment.
With respect to the male terminal fitting 52, the alignment of the leg portion 52B is not misaligned both during and after the mounting work of the male terminal fitting 52. Therefore, the leg portion 52B is inserted into the insertion hole H of the printed circuit board P.
When the lower end of the is fitted, the fitting work can be easily performed.

Further, in the connector 50 of this embodiment, the positioning means 5 for holding the alignment of the leg portion 52B.
Since the fitting projection 55 and the fitting hole 56 that form part 3 are integrally formed with the housing 51 and the male terminal fitting 52, respectively, the positioning means serves as the housing 51 and the male terminal fitting 5.
Compared with the case where the parts are separate from 2, the manufacturing, transportation, storage, etc. of the separate parts are unnecessary, and the cost can be kept low. Moreover, the positioning work requires male terminal fittings 5.
Since the work 2 is performed at the same time as the work of mounting the work 2 in the housing 51, the work efficiency is high. Further, since the positioning work can be performed individually for each of the male terminal fittings 52, even if the leg portion 52B is misaligned, the misalignment can be easily corrected and the fitting projection 55 and the fitting hole. The fitting of 56 can be performed efficiently and reliably.

In the present embodiment, the assembly can be performed by a procedure different from that described above. That is, the male terminal fitting 52 is preliminarily formed with the connecting portion 52A and the leg portion 52B in a straight line, and is press-fitted into the through hole 54 in this state, and then the male terminal fitting 52 is turned downward. At the same time as the leg portion 52B is formed by bending, the fitting protrusion 55 is formed.
And the fitting hole 56 are fitted together. At this time, the fitting hole 56 approaches the fitting projection 55 so as to draw an arc, but immediately before the fitting projection 55 is fitted into the fitting hole 56, the fitting projection 55 and the fitting hole 55 56, the front surface of the leg portion 52B does not abut the tip end surface of the fitting projection 55, and therefore the fitting projection 55 is located.
Smoothly fits into the fitting hole 56. Even with such a procedure, the leg portion 52B does not interfere with or get caught in the housing 51 or other members, so that the fitting protrusion 55 and the fitting hole 56 are surely fitted to each other so that the leg portion 52B is correct. Since it is held in the posture, there is no fear that the alignment of the leg portion 52B is disturbed. In addition, as described above, when the male terminal fitting 52 is mounted in the housing 51 in a straight line and then assembled by a bending process, the male terminal fitting 52 is mounted on the housing 51. Instead of fitting the connecting portion 52A in the through hole 54 from the rear side first, the leg portion 52B may be inserted in the through hole 54 from the hood portion 51B side first. When the fitting is performed in such a direction, a large resistance force can be generated between the through hole 54 and the connection portion 52A against an external force in the same direction as the fitting direction. Connect the terminal fittings to the connecting part 52
It is possible to prevent the connecting portion 52A from being displaced rearward in the through hole 54 due to the pressing force from the female terminal fitting when fitted to A.

Of course, also in this embodiment, the above-mentioned first embodiment is used.
Similarly, it is possible to ensure the alignment of the leg portions 62UB and 62LB after and after the mounting process of the male terminal fittings 62U and 62L. Further, the other actions and effects are the same as those in the first embodiment, and therefore the description thereof will be omitted.

<Other Embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments are also included in the technical scope of the present invention.

(1) In the above embodiment, the case where only one pair of the projecting piece and the fitting hole or the fitting projection 55 and the fitting hole which constitute the positioning means is provided has been described.
A plurality of pairs of positioning means may be provided for one male terminal fitting.

(2) In the above embodiment, the case where the convex fitting portion is formed on either one of the male terminal fitting and the housing as the positioning means and the fitting hole is formed on the other is explained. According to the present invention, both the convex fitting portion and the fitting hole are formed on both the male terminal fitting and the housing, and the convex fitting portion of the male terminal fitting and the fitting hole of the housing are fitted together. At the same time, the fitting hole of the male terminal fitting and the convex fitting portion of the housing can be fitted together.

(3) In the first embodiment, the protruding piece 36 is used.
Was formed by bending the portion protruding from the side edge of the leg portion 32B, but the protruding piece may be formed by other means such as cutting and raising the center portion of the leg portion in the width direction forward. it can. When the projecting piece has a plate shape, the projecting piece may be oriented at a right angle to the projecting piece and the plate surface may be horizontal.

(4) In the third embodiment, the male terminal fitting 52 makes the plate surface of the leg portion 52B face the rear surface of the housing 51. However, as in the second embodiment, the male terminal fitting is the plate. The surface may be oriented perpendicular to the rear surface of the housing. In this case, the fitting hole of the leg portion may be formed, for example, in a plate portion that is bent from the front edge of the leg portion to the left or right to project.

(5) In the third embodiment, the fitting hole 5
Although the front end portion of the fitting protrusion 55 protruding through 6 is crushed and deformed by crimping and fixed so that it cannot be pulled out, according to the present invention, the fitting protrusion is fitted into the fitting hole in a press-fitted state. It is also possible to leave the front end of the fitting projection as it is without crushing it. Even in this case, the frictional resistance due to the press-fitting can prevent the slip-out to some extent, and thus the misalignment of the leg alignment can be prevented.

(6) In the third embodiment, the fitting protrusion 5
A tapered conical guide surface may be formed at the tip of 5.
With this configuration, even if the position of the fitting hole with respect to the fitting protrusion is deviated, the tip of the fitting protrusion can be reliably fitted into the fitting hole without hitting the front surface of the leg portion.

(7) Through-hole 64 as in the fourth embodiment
Even when the U and 64L are arranged in upper and lower stages, it is possible to use the same type of male terminal fitting as that of the second embodiment in which the plate surface is oriented at right angles to the rear surface of the housing.

(8) In the fourth embodiment, the through hole 64
Although the case where U and 64L are arranged in two steps above and below is described, the present invention can be applied to the case where the through holes are arranged in three steps or more.
