Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an LED mounting spacer, and more particularly to an LED mounting spacer used for mounting an LED horizontally on a printed circuit board.
[0002]
[Prior art]
Conventionally, in order to attach a light emitting diode (hereinafter referred to as “LED”) to a printed circuit board, for example, a spacer described in JP-A-6-188535 has been proposed.
[0003]
As the spacer, a dedicated one is used independently for each LED mounting position. As shown in FIG. 7, when the LED 104 is mounted horizontally, the spacer 101 is placed on the printed circuit board 106, and the LED 104 is viewed from above. The lead 105 is inserted into the through hole 101b of the stepped portion 101a, protrudes to the lower side of the printed circuit board 106, and this portion is soldered. Thereafter, the LED 104 is bent in the arrow X direction to form a horizontal type. At this time, the mounting height of the LED 104 was adjusted by changing the height of the spacer 101, and the bending position of the lead 105 was adjusted by changing the height of the stepped portion 101a.
[0004]
[Problems to be solved by the invention]
However, in the above conventional LED mounting spacer, when a plurality of LEDs are mounted in the horizontal direction and mounted in the vertical direction with respect to the printed circuit board, the lead from the leading edge of the LED increases as the mounting position of the LED moves away from the printed circuit board. Since the distance to the bending position becomes large, there is a problem that the position of the tip of the LED becomes unstable. At this time, there is also a problem that parts for alignment are required.
[0005]
Furthermore, since the lead bending position changes according to the LED mounting height, there is a problem that the shape of the spacer must be changed according to the LED mounting height.
[0006]
Therefore, the present invention has been made in view of the problems in the conventional LED mounting spacer, and even when a plurality of LEDs are mounted horizontally in the vertical direction with respect to the printed circuit board, It is an object to provide an LED mounting spacer that does not become unstable, does not require positioning components, and does not need to change the shape of the spacer according to the LED mounting height. .
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 is an LED mounting spacer, which penetrates from a main body formed in a rectangular parallelepiped shape and from one surface of the main body to another surface facing the one surface. Two first through holes that pass through from one surface adjacent to the one surface to the other surface opposite to the one surface, and each of the second through holes intersects with each of the first through holes. A first protrusion standing on one surface where the first through hole is formed, and another surface opposite to the one surface where the first protrusion is formed, the LED or the first A first insertion hole into which the protrusion can be inserted, a second protrusion standing on the one surface where the second through hole is formed, and another surface opposite to the one surface where the second protrusion is formed. Two rod-shaped guide portions having a second insertion hole into which the second protrusion can be inserted and an inclined surface at the tip. When the guide portions are inserted into the first through holes, the first through holes and the second through holes are substantially completely closed by the inclined surfaces. It is characterized by.
[0008]
According to the first aspect of the present invention, the lead of the LED inserted from the first through hole is bent by the inclined surface of the guide portion inserted into the first through hole and exits through the second through hole. Therefore, no tool is required, and bending can be easily performed without paying attention to the bending position of the lead.
[0009]
Further, by inserting the second protrusion of one LED mounting spacer into the second insertion hole of the other LED mounting spacer, a plurality of LED mounting spacers can be mounted in the vertical direction with respect to the printed circuit board. At this time, since the second through holes of the plurality of LED mounting spacers are integrated, the distance from the bending position of the LED lead to the tip of the LED can be set at a constant interval without changing the type of component. Even if a plurality of LEDs are mounted horizontally in the vertical direction with respect to the printed circuit board, the tip position of the LEDs can be accurately aligned.
[0010]
Furthermore, by inserting the first protrusion of one LED mounting spacer into the first insertion hole of another LED mounting spacer, a plurality of LED mounting spacers can be mounted in a direction parallel to the printed circuit board. In this case, since the first through holes of the plurality of LED mounting spacers are integrated, the mounting position of the LED can be easily changed when mounting the LED in a horizontal direction in a direction parallel to the printed circuit board. There is no need to prepare a spacer.
[0011]
The invention according to claim 2 has two third insertion holes that penetrate from one surface where the second insertion hole is drilled to one surface opposite to the one surface and do not intersect the second insertion hole. It is characterized by that.
[0012]
Thus, when the lead of the electrical component is inserted into the third insertion hole and attached to the printed board, the lead of the electrical component and the LED lead do not contact each other, and the electrical component is densely placed on the printed board. Can be implemented.
[0013]
According to a third aspect of the present invention, there is provided a third projection that is erected on one surface where neither the first insertion hole nor the second insertion hole is formed, and a relative relationship with the one surface on which the third projection is formed. It has a third insertion hole which is drilled in the other surface facing and into which the third protrusion can be inserted.
[0014]
Thus, by inserting the third protrusion of one LED mounting spacer into the third insertion hole of the other LED mounting spacer, the plurality of LED mounting spacers are arranged in parallel to the printed circuit board. The LED can be mounted on the printed circuit board at regular intervals in the horizontal direction.
[0015]
