Description

[Detailed Description of the Invention] The present invention relates to a component mounting frame for mounting a large number of small components such as light emitting diodes (hereinafter referred to as LEDs) side by side.

Conventionally, in order to mount a large number of LEDs side by side on the same printed board, in order to make the upper part of the LED easier to see from the side, the lead 3 of each LED 2 is bent into an L shape as shown in Figure 1, and then attached to the printed board 1. Usually, they are inserted into lead holes provided and soldered, and then mounted side by side as shown in Figure B. At this time, the height H of each LED 2 with respect to the printed board 1 tends to be different. If there is any difference in height H, there is a disadvantage that it is unsightly when viewed from the outside. This point is particularly noticeable when monitoring LEDs that emit light from the direction of the P arrow. In addition, Figure 2 shows the LED 2 mounted on the auxiliary printed board 4 and the auxiliary printed board 4 and the printed board 1 connected with the connecting pin 5.The dimensions of the auxiliary printed board and the position of the lead holes must be made accurately. This is easy to do, so by inserting the LED leads into the holes on the auxiliary printed board without bending them, you can install a large number of LEDs in an orderly manner without any unevenness from side to side or front to back. However, it is necessary to connect the auxiliary printed board and the printed board with a large number of connection pins, which has the drawback of increasing the number of parts and man-hours.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a component mounting frame that allows a large number of components to be mounted on a printed circuit board in an easy, orderly and easily visible manner.

The purpose of this is a parts mounting frame for mounting a large number of small parts on the same printed board, and is made of insulating material and has an L-shaped cross section with a cutout in the lower part of the back surface. and a U-shaped band for attaching this block to the printed board, which passes through a plurality of mounting holes provided on the front surface of the block and a first back surface formed by a cutout from the bottom of each mounting hole. a lead hole;
a first lead groove provided on the first back surface so as to be continuous with the lead hole and reach the lower surface of the block; and a second back surface that is different from the first back surface and is spaced at the same interval as the lead groove. This is achieved by having a second lead groove provided in the second lead groove. It is convenient if the block has at least one knob on one side and a fitting hole on the other side into which a knob of the same size as said knob fits, and furthermore, the block from now on has a gap on the top side. It is convenient when connecting two or more blocks to have a fitting hole into which a knob of the same size as the knob fits.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The component mounting frame according to the present invention consists of a block 6 made of an insulating material and having an L-shaped cross section as shown in FIGS. 3A and 3B, and a U-shaped band 16 as shown in FIG. 3D. A large number of mounting holes 7 having a constant diameter and a constant depth are provided in a straight line at regular intervals on one side of the back surface so that the LED 2 can be almost buried therein.

A lead hole 8 (shown in FIG. 3C) is provided that penetrates from the bottom of each hole 7 to the opposite surface of the hole 7, and the end surface of this side is continuous with the lead hole 8 on the opposite surface of the mounting hole 7. The first lead groove 10 reaches 9
is provided. Furthermore, second lead grooves 11 are provided on the end face of the other side of the block 6 at the same spacing as the first lead grooves 10. Further, on both sides of the block 6, one knob 12 and a fitting hole 13 into which a knob of the same size as this knob 12 is fitted are provided so as to be spaced apart and opposite to each other. Furthermore, a knob 14 and a fitting hole 15 into which a knob of the same size as the knob 14 is fitted are provided at intervals on the back surface of the other side of the block 6. To mount the LED 2 on the printed board, first pass the lead 3 through each lead hole 8 as shown in Figure 3C, and then insert each LED 2 into its respective mounting hole 7 until it touches the bottom of the hole 7. After that, each lead 3 is made to protrude from the bent end surface 9 along the first lead groove 10.

Then, as shown in FIG. band 1
Bend and secure the tip of leg 6, and solder lead 3. At this time, block 6 of band 16
The block 6 and the band 16 are integrated by providing fitting holes at positions corresponding to the knobs 12 and 14 provided in the block 6 and the band 16, respectively. In this way, the LEDs can be easily installed on the printed board in a straight line at a constant height, without vertical disturbances or irregularities in the front and back. Moreover, since the positions of the leads are regulated by the lead grooves, they can be inserted into the holes of the printed board at the same time, which is easier than mounting the LEDs individually on the printed board.

If a large number of LEDs are to be attached, as shown in FIG.
6' knob 14 is fitted into the fitting hole 15 and connected, the LED 2 is inserted into each mounting hole 7, and the lead 3 of the LED 2 inserted into the lower block 6 is inserted along the first lead groove 10. Bend, upper block 6'
The leads 3 of the LED 2 inserted into the block 6 are bent along the second lead groove 11, so that all the leads 3 are lined up and protrude from the end face 9 side of one side of the block 6, and the U-shaped band 16 (the fifth (see figure) to fix it to the printed board 1, and solder the leads 3 to the printed board 1. At this time, since the block has an L-shaped cross section and two lead grooves, the LED leads attached to the upper block and the LED leads attached to the lower block will come into contact with each other. If the printed board has two rows of holes for inserting the leads, they can be inserted into the holes at the same time, which is easier than installing the LEDs individually. It is also possible to arrange the blocks 6 horizontally in two rows, and if there are a large number of LEDs, stacked blocks 6 and 6' can be arranged horizontally and connected by a band 16 to form a printed board, as shown in FIG. It can also be attached to 1. At this time, the knobs 12, 14 and their fitting holes 13, 15 serve to hold the blocks so that they do not shift relative to each other.

The component mounting frame of this invention is useful when arranging many conductive wires 17 side by side on the printed board 1 as shown in Figure 6A, in addition to LEDs and other components.In this case, as shown in Figure 6B, conductor 17
Peel off the coating from the tip of the block 6 and insert it into the mounting hole 7 of the block 6.
Insert the conductive wire 17 until the end of the sheath comes into contact with the lead hole 8, and insert the bare wire protruding from the lead hole 8 into the first lead groove 10.
The block 6 may be bent along the printed board 1, inserted into the hole of the printed board 1, and fixed with the band 16. In this way, the conductive wires can be routed simultaneously and orderly on the printed board.

As described above, the present invention is a component mounting frame in which a component mounting hole is provided on one side of an insulating block having an L-shaped cross section, and a lead hole and a lead groove are also provided. They can be arranged neatly in a straight line and easily attached to a printed board using a band. Also, if there are many parts,
This can be handled by stacking two or more blocks and joining them side by side. In this case, since the cross section of the block is formed into an L-shape and the leads are regulated by the lead grooves, there is no confusion between the leads of the upper block and the leads of the lower block. It is particularly useful as a mounting frame for LEDs whose light emission is constantly monitored from the outside, as the LEDs are housed in separate frames, making them easy to see.
