DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a right angle connector, and more particularly to a right angle connector which is mounted on a printed board by inserting a vertical terminal portion of an L-shaped terminal into a hole of the printed board.

It is desirable that the right-angle type connector be constructed so that it can be smoothly mounted on a printed board.

[0003]

9 and 10 show an example of a conventional right angle type connector 10. The connector 10 includes an insulating connector body 11, an insulating bracket 12, and
It is composed of a plurality of terminals 13.

The terminal 13 is L-shaped and has a horizontal terminal portion 13a and a vertical terminal portion 13b. The horizontal terminal portion 13a of the terminal 13 penetrates the connector body 11 and is fixed. The vertical terminal portions 13b are arranged facing downward.
The bracket 12 is formed with a plurality of through holes 12a in an arrangement corresponding to the design arrangement of the vertical terminal portions 13b. The bracket 12 is attached to the connector body 11 by fitting the through holes 12a into the corresponding vertical terminal portions 13b and approaching the connector body 11 from the lower side thereof as indicated by an arrow Z1. The bracket 12 is the connector body 11
In the state where the vertical terminal portions 13b are attached to the through holes 12a, the vertical terminal portions 13b penetrate the corresponding through holes 12a, and the position is regulated by the through holes 12a.

The connector 10 is mounted on the printed board 20 by lowering it as indicated by the arrow Z2 and inserting the vertical terminal portions 13b into the corresponding holes 21 of the printed board 20 as shown in FIG. It

[0006]

However, in the conventional connector 10, the length L of the portion 13b-1 of the vertical terminal portion 13b protruding downward from the bracket 12 is used.
1 is a length sufficient to penetrate the corresponding hole 21 of the printed board 20, which is as long as about 5 mm. Therefore, the connector 1
The protruding portion 13b-1 while carrying 0
However, there is a risk of bending as indicated by the chain double-dashed line in FIG. If even one of the vertical terminal portions 13b is bent, the bent vertical terminal portion will be caught and the connector 10 will not be mounted on the printed board 20 as it is. In order to mount it, it was necessary to rework the bending of the vertical terminal part that was bent more than the allowable limit, and the mounting work was not efficient.

Incidentally, in recent years, the number of terminals has increased in the right angle type connector, and the pitch of the vertical terminal portions tends to be narrowed. Therefore, the degree of bending permitted in the vertical terminal portion becomes smaller, and the bending of the vertical terminal portion becomes a more important problem than in the past. Therefore, it is an object of the present invention to provide a right angle connector that solves the above problems.

As shown in FIG. 1, the rising wall 32c is fitted into the groove 35, and as shown in FIG. 2, the recess 43 is engaged with the claw 40 to be temporarily fixed. Temporary fixing means bracket 32
Means that it is attached to a position on the front side of the position where it is finally attached, in a state where it cannot be easily removed, and in a state where it can be moved to the final attachment position.

Although it is temporarily fixed, the rising wall 3
Since 2c is fitted in the groove 35, the bracket 32 is
The X1 and X2 directions and the Y1 and Y2 directions are positioned at the same position as the final mounting position with respect to the connector body 31. Further, the main body 32a has the above-described height H2.
And the vertical terminal portion 13b is located in each through hole 32a.
The tip (lower end) 13c of the is fitted. Therefore, the position of each terminal 33 is regulated in the vertical terminal portion 33b.

Here, as shown in FIGS. 1 and 2, the tip (lower end) 13c of the vertical terminal portion 13b is located inside the through hole 32a, and the tip 13c of the vertical terminal portion 13b is
It does not protrude below the bracket 32. Therefore, while the connector 30 is being transported, the vertical terminal portion 1
The tip 13c of 3b does not get caught on an external object, and therefore the vertical terminal portion 13b does not bend during handling. Therefore, as will be described later, when mounting the connector 30 on the printed board, it is not necessary to correct the bending of the vertical terminal portion, and the mounting work can be performed efficiently.

Next, the operation and operation when mounting the connector 30 on a printed board will be described. As shown in FIG. 1, in addition to the hole 21, the printed board 20A is provided with a positioning hole 50 corresponding to the pin portion 21.

First, as shown in FIG. 5 (A), the pin portion 4
2 is fitted into the positioning hole 50, and the connector 30 is placed on the printed board 20A. By fitting the pin portion 42 into the positioning hole 50, the connector 30 is positioned with respect to the mounting planned portion on the printed board 20A, and the respective through holes 32a of the bracket 32 become the holes 21 of the printed board 20A.
And the through hole 32a and the hole 21 are aligned in a straight line.

Next, the connector body 31 is pushed down in the Z2 direction to the final position shown in FIG. 5 (B). By this operation, the claw 40 slips out of the recess 43, and the claw 40 moves toward the inclined surface
6, while the arm 39 bends outward, the connector body 31
Will sink. When the connector body 31 sinks to the position where it abuts the printed board 20A, the arm 39 elastically restores and the claw 40 engages with the concave step portion 44. Furthermore, the bracket 32
Of the main body 32a of the main body 32a.
The one-direction end engages with the groove 37. As a result, the bracket 32 is fixed to the final mounting position of the connector body 31.

Further, when the connector body 31 sinks, the tip 13c of the vertical terminal portion 13b comes out of the through hole 32a, enters the hole 21, and reaches the position of the lower surface of the printed board 20A. Here, since the holes 21 are aligned with the through holes 32a, the tips 13c of the vertical terminal portions 13b do not collide with the upper surface of the printed board 20A, and the tips 13c of all the vertical terminal portions 13b enter the holes 21. It is smoothly inserted and inserted. Then, the tip side of the vertical terminal portion 13b is soldered to the printed board 20A by reflow.

Next, a right angle connector 30A according to a second embodiment of the present invention will be described with reference to FIGS. 6 to 8. The right angle connector 30A differs from the right angle connector 30 according to the first embodiment described above only in the bracket 32A. Bracket 32A
Does not have the pin portion 42.

As shown in FIGS. 6 and 7, the bracket 3
2A has a height H3 in which the main body 32a is slightly higher than the height H2.
It is located at and temporarily fixed. Instead of not having the pin portion 42 on the bracket 32A, a portion 13d near the tip 13c of the vertical terminal portion 13b projects downward from the main body portion 32a of the bracket 32A. The reason why the portion 13d near the tip 13c of the vertical terminal portion 13b projects downward from the main body portion 32a of the bracket 32A is that the projecting portion has the same role as the pin portion 42 of the above-described embodiment. The length L2 of the portion 13d protruding downward from the main body portion 32a of 32A is about 1 mm, which is significantly shorter than the corresponding length L1 in the conventional example shown in FIG.
Therefore, the portion 13d is difficult to bend, and the vertical terminal portion 13b does not bend during handling.

The connector 30A is mounted on the printed board in the same manner as the connector 30 according to the first embodiment. The printed board 20 does not have the positioning hole 50.
First, as shown in FIG. 8A, the tip portion 13d of the vertical terminal portion 13b is fitted into the corresponding hole 21, and the connector 30A is placed on the printed board 20.

By fitting the end portions 13d of the vertical terminal portions 13b into the corresponding holes 21, the connector 30A is positioned with respect to the mounting portion on the printed board 20. Next, the connector body 31 is pushed down in the Z2 direction to the final position shown in FIG. 8 (B).

By this operation, the claw 40 comes out of the recess 43, the claw 40 slides on the inclined surface 46, the arm 39 bends outward, and the connector body 31 sinks. Connector body 3
When 1 sinks to the position where it contacts the printed board 20A,
The arm 39 elastically restores, and the claw 40 engages with the concave step portion 44. Further, the rising wall 32c of the bracket 32 extends into the groove 35, and the rising wall 32b extends into the groove 36.
And the X1 direction end of the main body portion 32a is engaged with the groove 37. As a result, the bracket 32 is fixed to the final mounting position of the connector body 31.

Further, as the connector body 31 sinks, the tip portion 13d of the vertical terminal portion 13b further enters into the hole 21 and reaches the position of the lower surface of the printed board 20A. Then, the tip side of the vertical terminal portion 13b is soldered to the printed board 20 by reflow.

[0027]

As described above, according to the first aspect of the present invention,
Since the bracket is provisionally fixed to the position where the through hole fits with the tip of the vertical terminal portion by the temporary fixing means, there is no risk that the tip of the vertical terminal portion will hit an external object during handling, Accidents where the vertical terminal part bends during handling can be completely eliminated. Therefore, at the time of mounting, it is possible to eliminate the need to perform the work of correcting the bending of the vertical terminal portion bent more than the allowable limit. Moreover,
Since the bracket is provided with the positioning means for determining the mounting position of the right angle connector on the substrate, the right angle connector can be positioned at the mounting position by using this positioning means. Moreover, the connector main body can be sunk by the temporary fixing means. Therefore, the work efficiency of mounting the right angle connector can be improved.

According to the second aspect of the invention, in the state where the bracket is temporarily fixed by the temporary fixing means, the tip of the vertical terminal portion only slightly protrudes from the through hole. Therefore, the tip side of the vertical terminal portion is bent. Therefore, when mounting, it is possible to eliminate the need to perform the work of correcting the bending of the vertical terminal portion bent more than the allowable limit. Moreover, the right angle type connector can be positioned at the mounting position by utilizing the tips of the vertically protruding terminal portions. Moreover, the connector main body can be sunk by the temporary fixing means. Therefore, the work efficiency of mounting the right angle connector can be improved.
