Description of the Related Art As a printed circuit board connector, one disclosed in Japanese Patent Application Laid-Open No. Hei 3-11566 is known. As shown in FIG. 10, the female terminal fittings 3 are assembled in cavities 2 arranged side by side in a connector housing 1. The female terminal fitting 3 is provided with a strip 5 extending to the outside of the connector housing 1 at the rear end of the connecting portion 4 connected to the male terminal fitting, and the strip 5 is provided with a female terminal. The metal fitting 3 has a soldering portion 5a which is bent in the insertion / removal direction with respect to the cavity 2 so as to be deformable and then soldered to the printed circuit board 6 at its rear end. The reason why the strip portion 5 is bent so as to be able to bend and deform is to reduce the stress applied to the soldering portion 5a by inserting and removing the mating connector by bending and deforming, thereby preventing solder cracking. . [0003] However, in the above configuration, the female terminal fitting is formed in a box shape, whereas the strip portion has a thin band shape. When assembled inside, a play space is formed between the strip and the inner wall surface of the cavity. Therefore, there is a possibility that the soldering portion formed at the end of the strip portion may be loose and easily deformed by an external force during transportation or mounting. In addition, the wobble of the soldered portion makes it difficult to position the soldered portion with respect to the printed circuit board, and reduces the work efficiency. On the other hand, some terminal fittings are provided with a stabilizer for facilitating the insertion of the terminal fitting into the strip, but this is a structure which merely engages with the inner wall surface of the cavity. As a result, the movement in the direction of the inner wall surface to be engaged is restricted, but it is allowed to move in a direction perpendicular to the direction, which is incomplete in preventing the wobble of the soldered portion. . The present invention has been made in view of the above circumstances, and an object thereof is to provide a printed circuit board having a terminal fitting having a soldered portion at an end of a strip portion, in which wobbling of the soldered portion is regulated. To provide connectors. According to a first aspect of the present invention, there is provided a connector for a printed circuit board having a terminal housing in a connector housing, and a terminal housing in the terminal housing. A terminal fitting having a connecting part connectable to the terminal fitting and a strip extending from the connecting part to the terminal receiving chamber so as to be freely movable with respect to the terminal receiving chamber is accommodated, and the strip is extended. In a printed circuit board connector having an end portion which is a soldering portion that can be soldered to a printed circuit board, the strip portion and the connector housing have an engaging portion and an engaging receiving portion which can be engaged with each other. The movement of the strip is restricted by the engagement between the engagement portion and the engagement receiving portion, and the strip is connected to the terminal metal.
Tool can be bent and deformed in the insertion / removal direction with respect to the terminal accommodating chamber.
The soldering portion is connected via a bending portion.
The engaging portion is formed between the bending portion and the soldering portion.
An engagement protruding piece projecting between the engagement receiving portions,
The above-mentioned engaging projection can be inserted in the connector housing.
The engagement receiving portion is a terminal fitting.
Is disposed at an assembling opening for assembling the terminal into the terminal accommodating chamber.
And at the time of assembling the terminal fitting with the connecting portion.
In order to avoid interference with the engaging portion,
The inner wall is cut off diagonally from the installation port to the back
It is characterized by having According to the first aspect of the present invention, when the terminal fitting is assembled in the terminal receiving chamber of the connector housing, the strip is formed by the engagement between the engagement portion and the engagement receiving portion. Is restricted with respect to the terminal accommodating chamber. Therefore, the soldered portion formed at the extended end of the strip does not wobble, thereby preventing deformation at the time of transportation or assembling, and improving the workability by facilitating the positioning work on the printed circuit board. Can also be planned. [0007] Also, the engaging protrusion formed on the strip portion connector

Accordingly, solder cracking can be prevented. [0008] Further, whether one inner wall surface of the terminal accommodating chamber is an assembly port or not.
The terminal fittings are notched diagonally from
To avoid interference with the engagement receiving part
It is inserted obliquely into the terminal receiving chamber. Therefore,
Even if the engagement receiving part is provided, the terminal
Interference between the connection portion and the engagement receiving portion can be avoided. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment A first embodiment of a printed circuit board connector according to the present invention will be described below with reference to FIGS. As shown in FIG. 4, the connector for a printed board according to the present embodiment includes a connector housing 10 in which a plurality of cavities 11 are juxtaposed, and a female terminal fitting 20 to be assembled in each of the cavities 11. . The female terminal fitting 20 is, as shown in FIG.
On the distal end side (lower left side in FIG. 1), there is provided a connecting portion 21 into which a male terminal fitting (not shown), which is a mating terminal fitting, is inserted. An elastic contact piece (not shown) that can be contacted is provided. A locking hole 21a is formed in the upper surface of the connection portion 21. When the female terminal fitting 20 is inserted into the cavity 11, the lance 12 protruding into the cavity 11 is engaged. Are prevented from falling out of the cavity 11. A strip 22 extending outward from the connector housing 10 is connected to the rear end of the connecting portion 21. This strip 22 is located on the lower side (the lower side in FIG. 4).
A bent portion 22a that can bend and deform in the front-rear direction (the direction in which the male terminal fitting is inserted and withdrawn, ie, the left-right direction in FIG. 4), and a printed board (not shown) And a soldering part 22b to be soldered. The reason why the soldering portion 22b is connected to the connection portion 21 through the bending deformation portion 22a is that the bending deformation portion 22a bends in the insertion / removal direction when the male terminal fitting is inserted / extracted. This is because the stress applied to the male connector can be reduced, thereby preventing solder cracking when inserting and removing the male connector. Further, the strip 22 has a bending deformation portion 22a.
At the left and right edges (both edges extending in the length direction), engagement projecting pieces 23, 23 project substantially horizontally between the and the soldering portion 22b. When the female terminal fitting 20 is attached to the cavity 11, the engaging projection 23 fits into an engaging groove 13 of the connector housing 10 described later. The left and right edges of the soldering portion 22b are bent downward at substantially right angles to form a channel, thereby increasing the rigidity of the soldering portion 22b. On the other hand, each of the cavities 11 juxtaposed in the connector housing 10 has a square hole, and an insertion port 11a for inserting a male terminal fitting is formed at the front end thereof, and at the rear end thereof. Has an assembling opening 11b for inserting the female terminal fitting 20 into the cavity 11. In this assembling opening 11b, the upper ends of the left and right side walls (the left and right side walls in FIG. 5) are slightly opposed to each other and protrude inward. An extending engagement groove 13 is formed. And the female terminal fitting 20
Is assembled into the cavity 11, the engagement protrusion 23 of the female terminal fitting 20 is fitted into the engagement groove 13, and the upper and lower directions of the strip 22 (up, down, left, and right directions in FIG. 5). All movements are regulated. The bottom surface of the cavity 11 is cut obliquely from the center to the rear end in the length direction, so that the female terminal fitting 20 is inserted obliquely into the cavity 11. That is, in order to avoid interference between the connecting portion 21 and the protruding portion 14, the connecting portion 21 is pushed backward so as to pass through the lower side of the protruding portion 14. Next, the assembling work of the female terminal fitting 20 will be described. The female terminal fitting 20 is inserted into the mounting opening 11b of the connector housing 10 from the connection portion 21 side (see FIG. 2). Then, the connecting portion 21 is obliquely pushed along the bottom surface, and when the connecting portion 21 has passed through the protruding portion 14 in the assembling opening 11b, the connecting portion 21 is leveled and further carried to the far side (see FIG. 3). Then, as the female terminal fitting 20 is inserted into the regular assembling position, the engaging projection 23 is inserted into the engaging groove 13. When the female terminal fitting 20 is inserted into the proper assembling position as shown in FIG. 4, the engaging projection 23 is completely fitted into the engaging groove 13 and the strip 2
2 is regulated in the vertical and horizontal directions (see FIG. 5). As described above, in the present embodiment, since the movement of the strip 22 in the vertical and horizontal directions can be restricted, the soldering portion 22 formed at the extended end of the strip 22 is formed.
As a result, the soldering portion 22b is less likely to be deformed during transportation, assembly, and the like, and the positioning operation with respect to the printed circuit board is facilitated, so that the workability can be improved. Also, assembling port 11b
Even when the projection 14 having the engagement groove 13 is provided, the bottom surface of the rear end side of the cavity 11 is notched obliquely, so that when the female terminal fitting 20 is inserted, the female terminal fitting 20 and the projection 14 interfere. Can be avoided. [0017] <First Example> Hereinafter, will be described with reference to FIGS. 6 and 7 for the first embodiment of the present invention. The difference between the present embodiment and the first embodiment is as follows.
The shape of the engaging projection and the engaging groove is the same as that of the first embodiment, and the other parts are the same as those of the first embodiment. As shown in FIG. 6, the engaging projection 31 of the present embodiment is located horizontally between the bending portion 22a and the soldering portion 22b from its left edge (right edge in FIG. 7). After that, it is bent vertically upward and folded at right angles to the strip 22 side. On the other hand, as shown in FIG.
After extending inward from the rear end surface in the upper part of the assembling opening 11b, the cross-sectional shape extends upward from the upper right corner (upper right corner in FIG. 7) of the assembling opening 11b in rear view, and then bends inward at right angles. L-shaped. Also, cavity 1
1 has a straight square hole without the bottom not being cut off diagonally as in the first embodiment. Then, the female terminal fitting 20 is connected to the mounting port 11b.
When the female terminal fitting 20 is inserted into the regular assembling position when inserted into the cavity 11 through
The engaging projection 31 is inserted into the engaging groove 32. Accordingly, when the female terminal fitting 20 is assembled at the regular assembling position, the engagement protrusion 31 and the engagement groove 32 are fitted to each other, so that the movement in the vertical and horizontal directions with respect to the strip 22 is restricted. As in the first embodiment, it is possible to prevent wobbling of the soldering portion 22b formed at the extended end of the strip 22. In the present embodiment , the engagement groove 32 is provided in the upper portion of the mounting opening 11b, and it is not necessary to insert the female terminal fitting 20 obliquely as in the first embodiment, so that the mounting operation is easy. is there. < Second Reference Example > A second embodiment of the printed circuit board connector of the present invention will now be described .
Two reference examples will be described with reference to FIGS. Book
The difference between the reference example and the first embodiment lies in the shape of the strip portion and the engagement groove, and the other portions have the same configuration as in the first embodiment. The description is omitted. As shown in FIG. 8, the strip 41 of the present reference example is bent downward from the rear end of the connecting portion 21 to form a bending deformation portion 41a as in the first embodiment. The end on the extension side protrudes higher than the upper surface of the connection portion 21, and the soldering portion 41b is formed from that position. In addition, connection section 2
Engagement projections 23 are formed on both left and right edges of the connecting portion between the bending portion 41a and the soldering portion 41b which protrude higher than the upper surface of the first member 1 as in the first embodiment. On the other hand, as in the first embodiment, the cavity 11 has a straight rectangular hole without a diagonally cut bottom, and as shown in FIG. An engagement groove 42 is formed inward from the rear end face. Then, the female terminal fitting 20 is connected to the mounting port 11b.
When the female terminal fitting 20 is inserted into the regular assembling position when inserted into the cavity 11 through
The engaging projection 23 is inserted into the engaging groove 42. Thus, when the female terminal fitting 20 is assembled at the regular assembling position, the movement in the up, down, left, and right directions with respect to the strip 41 is restricted. Can be. Also, cavity 1
1 has a straight square hole, and the female terminal fitting 20 can be inserted straight, so that the assembling work is easier than in the first embodiment. The present invention is not limited to the above-described embodiment, but can be modified and implemented as follows, for example, and these embodiments also belong to the technical scope of the present invention. (1) In the above embodiment, the present invention is applied to the female terminal fitting 20.
Although the example applied to (1) was shown, it is also possible to apply to a male terminal fitting. (2) In the above embodiment, the strip 22,
Although the flexible deformation portions 22a and 41a are formed on the 41, the strip portion may be formed in a shape extending straight without forming this. (3) In the above embodiment, the strip 22,
The engaging projections 23, 31 are formed on the 41 side, and the engaging grooves 13, 32, 42 are formed on the connector housing 10 side. On one side, an engagement hole engageable with the engagement projection may be formed. In other words, the mutually engageable engagement portion and the engagement receiving portion are defined as the band piece side. Any structure may be provided as long as it can be provided on the connector housing side and thereby can restrict the movement of the strip in the vertical and horizontal directions (the direction perpendicular to the direction of insertion into the cavity). (4) In the first embodiment, the engaging projection 23 is set so as not to protrude beyond the width of the connecting portion 21. An engagement groove may be formed on the left and right inner wall surfaces of the cavity so that the engagement protrusion can be engaged with the engagement protrusion. In this configuration, since it is not necessary to provide a protrusion to form the engagement groove, it is not necessary to diagonally cut the bottom surface of the cavity to avoid interference between the protrusion and the female terminal fitting. In addition, the present invention can be variously modified and implemented without departing from the gist.
