Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a terminal press-fitting jig and a press-fitting device for press-fitting a terminal of a press-fit connector into a printed circuit board, for example.
[0002]
[Prior art]
FIG. 7 is a side view showing an example of a state of a conventional press-fit connector before press-fitting terminals into a substrate, and FIG. 8 is a perspective view showing an example of a process of inserting each terminal of the conventional press-fit connector into a connector jig. (A) shows the state at the time of insertion, and (b) shows the state after the end of insertion. FIG. 9 is a partially enlarged view seen from the B direction in FIG.
[0003]
Conventionally, a so-called press-fit connector (PFC) has been widely used as a connector that allows simple connection that does not require soldering by simply press-fitting a terminal into a substrate. As a method for press-fitting this terminal, for example, as shown in FIG. 7, a plurality of hooked terminals 512 extending from the housing 511 of the press-fit connector 510 are arranged in the lateral direction of the connector jig 520 (perpendicular to the paper surface of the figure). In a state of being sandwiched between the comb teeth and further constraining each terminal 512 by the through hole 542 of the alignment plate 540, the flange portion 512b of each terminal 512 is pushed by the pressing surface 521 of the connector jig 520, and the vicinity of the tip of each terminal 512 A method is known in which an elastic portion 512 a (see FIG. 9) in which a needle is bulged into a needle shape is press-fitted into each through hole 532 of the printed circuit board 530.
[0004]
Normally, each terminal 512 is set on the connector jig 520 prior to press-fitting the printed circuit board 530 into each through hole 532. At this time, as shown in FIGS. The method of inserting the terminal 512 between the comb teeth 522 has been taken (this method is similarly adopted for a so-called pin connector for soldering each terminal to the substrate as in Patent Document 1, for example). . Note that reference numeral 550 in FIG. 7 denotes a substrate jig on which the printed circuit board 530 comes into contact with the back surface during press-fitting, and the tip of each terminal 512 enters the bottomed hole 552 to be protected.
[0005]

Japanese Patent Laid-Open No. 6-224597 [0006]
[Problems to be solved by the invention]
However, in the above prior art, a taper 523 is required on the pressing surface 521 in order to draw each terminal 512 of the press-fit connector 510 between the comb teeth 522 of the connector jig 20 as shown in FIG. Increasing the taper 523 reduces the contact area between the flange portion 512a of each terminal 512 and the pressing surface 521, as shown in FIG.
[0007]
When the contact area is reduced, the terminal 512 is deformed by the pressure input, and a desired press-fit amount cannot be obtained, which may reduce the reliability of the connector.
[0008]
The present invention solves such a problem of the prior art, and increases the contact area between the pressing surface of the jig main body and the terminal flange, thereby improving the reliability of the connector terminal press-fitting jig. And a press-fitting device.
[0009]
[Means for Solving the Problems]
According to the first aspect of the present invention, the plurality of flanged terminals extending from the housing of the connector are supported by a jig body having at least a contact surface capable of contacting the flange of each terminal and a surface perpendicular to the contact surface. A jig for press-fitting into each through hole of the substrate in a state, wherein each terminal is moved inward from a surface orthogonal to the contact surface, with the flange portion of each terminal floating from the contact surface. The jig main body is formed with a guiding portion for guiding and guiding each terminal that has been guided inward by the guiding portion in a direction in which the flange portion of each terminal further contacts the contact surface. It is characterized by this.
[0010]
According to the above-described configuration, a plurality of hooked terminals extending from the housing of the connector, a lead-in portion that draws inward from a surface orthogonal to the contact surface, with the flange portion of each terminal floating from the contact surface, Since the guide body that guides each terminal that has been guided inward by the guide portion in a direction in which the flange portion of each terminal further abuts against the contact surface is formed on the inside of the jig body, The contact area between the contact surface and the flange of the terminal is increased. For this reason, the support of the terminal becomes strong, and the deformation of the terminal flange portion hardly occurs due to the pressurizing force in the substrate press-fitting process, and as a result, the press-fit reliability is improved.
[0011]
According to a second aspect of the present invention, the guide portion has a first inclined surface that is expanded from the inner side toward a surface orthogonal to the contact surface, and the first inclined surface is contacted from the inner side. If it is set to be larger than the second inclined surface expanded toward the contact surface, for example, the opening angle of the taper as the first inclined surface can be increased. The possibility of interference with the main body is reduced, and the terminal is less likely to be deformed when the jig is set. For this reason, the alignment of the terminals is less likely to be disturbed, and when the board is set, the terminals easily enter the through holes of the board.
[0012]
If the lead-in portion is formed of a synthetic resin material as in the invention described in claim 3, for example, the taper as the first inclined surface is coated with a resin, or a separate part from the jig body. By comprising synthetic resin parts, the possibility of scraping the terminals with this jig body is reduced.
[0013]
According to a fourth aspect of the present invention, the guide portion has a groove or a protrusion that guides the housing together with each terminal, while the housing has a protrusion or a groove that can be engaged with the groove or the protrusion. Then, when the connector is set on the jig, they serve as a guide, so that the terminal and the jig body are less likely to interfere with each other.
[0014]
As in the invention described in claim 5, the substrate on which the substrate jig is brought into contact from the back surface and each terminal supported by the terminal press-fitting jig in any one of claims 1 to 4 are opposed to each other. If the terminal is pressed into the board by pressing at least one of the board jig and the press-fitting jig in a state, the contact area between the contact surface of the jig body and the terminal flange A press-fitting device that can perform a good press-fitting is obtained.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a side view showing a state before press-fitting terminals of a press-fit connector according to an embodiment of the present invention into a board.

[0017]
The press-fit connector 10 includes a synthetic resin housing 11 having a substantially rectangular parallelepiped shape as a whole, and metal pin-like terminals 12 extending in parallel from the housing 11. In the drawing, each terminal 12 protrudes from the housing 11 in the horizontal direction and is then bent upward at a right angle to form an L shape. In order to prevent the terminals 12 from interfering with each other, three in the vertical direction (left-right direction in FIG. 1) and three in the horizontal direction (perpendicular to the plane of FIG. 1) are arranged in a plan view. Yes. The shape and number of each terminal 12 vary depending on the type and size of the press-fit connector 10.
[0018]
Near the tip of each terminal 12, an elastic portion 12 a (see FIG. 3) is formed that bulges in the shape of a needle so that it can be elastically press-fitted into each through hole of the printed circuit board 30. The intermediate portion is formed with a flange portion 12b protruding from the terminal body so that a pressing surface 21 as a contact surface of the connector jig 20 is caught.
[0019]
The connector jig 20 is for supporting the terminals 12 in the lateral direction during press-fitting, and is made of a substantially rectangular parallelepiped jig main body 22 and a deep groove 23 engraved in the jig main body 22 so as to be arranged in the lateral direction. have. Therefore, the jig body 22 has a deep comb shape when viewed from the front side.
[0020]
The printed circuit board 30 includes a thin plate-shaped substrate body 31 and through holes 32 penetrating the substrate body 31 at portions corresponding to the terminals 12.
[0021]
The alignment plate 40 is used to support the terminals 12 in both the vertical and horizontal directions during press-fitting. The plate body 41 is made of a synthetic resin and has a substantially rectangular parallelepiped shape, and the plate body 41 is aligned in both the vertical and horizontal directions corresponding to the terminals 12. A through hole 42 is provided. Therefore, the through holes 42 of the alignment plate 40, together with the lateral grooves of the connector jig 20, serve to accurately align the terminals 12 in both the vertical and horizontal directions on the pressing surface 21 of the connector jig 20. Fulfill.
[0022]
The substrate jig 50 is for pressing the printed circuit board 30 during press-fitting. The thick plate-shaped jig main body 51 and the terminals 12 penetrating the through holes 32 of the printed circuit board 30 are inserted into the jig main body 51. A bottomed hole 52 is formed for protection.
[0023]
2A and 2B are perspective views showing the detailed configuration of the connector jig that characterizes the present invention. FIG. 2A shows a state when the terminal is inserted into the connector jig, and FIG. 2B shows a state when the insertion is completed. FIG. 3 is a partially enlarged view seen from the direction A in FIG.
[0024]
As shown in FIG. 2, the jig main body 21 of the connector jig 20 has a lead-in portion 23 a that draws each terminal 12 inward from a surface 24 orthogonal to the pressing surface 21 while slightly floating from the pressing surface 21. Further, a guide portion 23b for guiding each terminal 12 guided by the guide portion 23a in a direction in which the flange portion 12b of each terminal 12 abuts against the pressing surface 21 is formed.
[0025]
The guiding portion 23a has a first inclined surface 24a that is expanded toward a surface 24 that is orthogonal to the pressing surface 21, and the first inclined surface 24a is, as shown in FIG. It is set to be larger than the second inclined surface 21a that is expanded toward the front. Thereby, since the first inclined surface 24a can be made as large as possible, the possibility of interference between the terminal 12 and the jig body 22 is reduced, and the terminal 12 is deformed when the connector jig 20 is set. It becomes difficult. In addition, the alignment of the terminals 12 is less likely to be disturbed, and the terminals 12 are likely to enter the through holes 32 of the printed circuit board 30 when the printed circuit board 30 is set. The first inclined surface 24a and the second inclined surface 21a may be straight or arcuate. In addition, there is a parallel surface 24b at the tip of the first inclined surface 24a, and along these inclined surfaces 24a and 21a and the parallel surface 24b, the terminal 12 is located inside the surface orthogonal to the pressing surface 21 of the connector jig 20. You are invited smoothly.
[0026]
Further, the guiding portion 23a is formed by resin-coating the first inclined surface 24a or by forming it with a synthetic resin component separate from the jig main body 22 and bonding it to the jig main body 22. The possibility of scraping the terminal 12 with the main body 20 is reduced.
[0027]
The guide portion 23b is composed of a parallel surface 24b continuous with the parallel surface 24b of the guide portion 23a (the same number is used here because it is continuous with the parallel surface 24b of the guide portion 23a). As a result of the terminal 12 being pushed down and smoothly guided toward the pressing surface 21 of the jig body 22, the flange 12 b is accurately aligned in the lateral direction on the pressing surface 21. The vertical alignment is achieved by inserting each terminal 12 into the through hole 42 of the alignment plate 40 described above.

In the figure, the substrate jig 50 is pressed in a state where the printed circuit board 30 with which the substrate jig 50 abuts from the back and the terminals 12 supported by the connector jig 20 of the press-fit connector 10 are opposed to each other. Thus, each terminal 12 is press-fitted into the printed circuit board 30.
[0033]
For example, hydraulic or electric motors are used as drive mechanisms such as the slide table 102, the floating table 103, the elevating mechanism 105, and the press mechanism 107, and their operations are controlled by a control device (not shown). ing.
[0034]
FIG. 5 is a side view showing the state of each part in each step of the press-fitting method using the press-fitting device, where (a) shows a state before the terminal is inserted into the connector jig, and (b) shows the terminal used in the connector jig. (C) is a state when the terminal is further inserted into the connector jig, (d) is a state when the terminal is inserted into the connector jig, and (e) is a state where the terminal is pressed by pressing the board jig. (F) shows the completed state. FIGS. 5B and 5C correspond to FIGS. 2A and 2B, respectively. Also, here, after each component is mounted at the moving position in the direction of the white arrow in the figure by the slide table 102, the floating table 103, etc. of the press-fitting device 100 in FIG. It is assumed that it has been set to a predetermined position.
[0035]
First, the connector jig 20 held by the lifting mechanism 105 is inserted into the intermediate portion of each terminal 12 from the side of the press-fit connector 10 held by the connector set jig 104. At this time, as shown in FIG. 5A, the terminals 12 are moved down together with the housing 11 with respect to the connector jig 20 by the operation of the lifting mechanism 105, and the slide table 102 to which the connector set jig 104 is fixed is fixed.

Therefore, according to the connector jig 20 of this embodiment, the plurality of hooked terminals 12 extending from the housing 11 of the press-fit connector 10 are connected to the hook parts 12b of the terminals 12 by the guide parts 23a formed on the jig main body 22. Each terminal 12b is guided inward from a surface 24 perpendicular to the abutting pressing surface 21, and each terminal 12b is further guided inside by a guide portion 23b formed in the jig body 22. Since the 12 flange portions 12b are guided so as to contact the pressing surface 21, as shown in FIG. 3, the contact area between the pressing surface 21 of the jig body 22 and the flange portion 12b of the terminal 12 increases. . For this reason, the support of the terminal 12 is strengthened, and the deformation of the terminal flange 12b is hardly caused by the pressure applied in the press-fitting process to the printed circuit board 30. As a result, the reliability of the press-fitting is improved. As a result, it is possible to realize press-fitting of a press-fit connector that is inexpensive and can improve reliability.
[0038]
Next, as shown in FIG. 5D, the tip of each terminal 12 (up to the front of the elastic portion 12a in FIG. 3) is passed through the through hole 32 (see FIG. 1) of the printed circuit board 30.

And the bridge | crosslinking part 107b of the press mechanism 107 descend | falls, and as shown in FIG.5 (e), it presses from upper direction in the state which covered the printed circuit board 30 with the board | substrate jig | tool 50. FIG. Then, the elastic portion 12a of each terminal 12 is completely inserted into the through hole 32 of the printed circuit board 30 in a contracted state. Thereby, each terminal 12 is fixed to the printed circuit board 30. Thereafter, when the substrate jig 50 pressed by the press mechanism 107 is pulled upward and the connector jig 40 held by the elevating mechanism 105 is pulled downward, the press-fit connector 10 is shown in FIG. Completed as shown.
[0039]
That is, according to the press-fitting device 100 of this embodiment, it is possible to increase the contact area between the pressing surface 21 of the jig body 22 and the flange 12b of each terminal 12 and perform good press-fitting.

On the other hand, the housing 11 has a protrusion 13 that can be engaged with the groove 25. The extended portion has a concave shape in a front view in which both left and right ends of a flat bottom surface are raised to the same height, and the groove 25 is formed by notching the rising portions in two left and right symmetry. Further, the protrusions 13 are formed by projecting the portions corresponding to the grooves 25 on the bottom surface of the housing 11 in two places on the left and right.
[0042]
However, the connector jig 20 may have a protrusion instead of the groove 25, and the press-fit connector 10 may have a groove that can be engaged with the protrusion instead of the protrusion 13. Further, the pairs of the groove 25 and the protrusion 13 do not necessarily need to be provided in two places symmetrically in the left-right direction, and may be provided, for example, one place, three places or more, or left-right asymmetry. For example, two pairs of the left groove 25 and the protrusion 13 may be provided, and only one pair of the right groove 25 and the protrusion 13 may be provided to form a staggered pattern on the left and right.
[0043]
And the connector jig 20 hold | maintained at the raising / lowering mechanism 105 is inserted in the intermediate part of each terminal 12 from the side of the press fit connector 10 hold | maintained at the connector set jig 104.
