Abstract

PURPOSE:To attach simply a spacer tube to the foot of an electronic part by inserting the spacer tubes into tube inserting holes spaced from each other by the approximately same gap as that between the feet of two lead wires of the electronic part to insert the feet of the electronic part into the spacer tubes. CONSTITUTION:When a tube arranging plate 14 is placed in a normal position, a portion of the upper tip of a pin 22 enters the lower part of a tube inserting hole 36 in the tube arranging plate 14. When under such condition a great amount of spacer tubes T are inputted into a recess 32 of the tube arranging plate 14 and the whole inserting jig 10 is swung back and forth horizontally, the spacer tube T enters an expanded part 38 and further vertically the tube inserting hole 36. Next, after the feet L of lead wires such as resistors R or the like are inserted in the respective spacer tubes T and pins 22, the tube arranging plate 14 is depressed downward to be latched and locked on an arm lock 24. Then, the resistor R and spacer tube T are held together between one's fingers to be drawn out.

2. Description of the Related Art When an electronic component such as a resistor (R) is mounted on a printed circuit board, a leg (L), which is a lead wire, is inserted into a mounting hole of the printed circuit board and separated from the surface of the printed circuit board. In order to obtain a predetermined height, a spacer tube (T) made of a heat-resistant synthetic resin material was manually inserted into each of the legs as shown in FIG.

Then, the electronic parts such as the resistor (R) after inserting the spacer tube (T) into the foot are erected by sticking the foot (L) into the sponge sheet in order to maintain the inserted state. This is the work before mounting the electronic components on the printed circuit board.

At the time of assembling the printed circuit board, the electronic components stabbed in the sponge sheet in the pre-mounting process are picked out together with the spacer tube (T) by hand and mounted on the printed circuit board.

As described above, the insertion of the spacer tube (T) into the leg (L), which is the work before mounting the electronic component, is performed on each leg (L) of the resistor (R) which is the electronic component. Since (T) is a work to insert by hand, it is very troublesome, and the diameter of the leg (L) of the electronic component is about 0.4 mm, and the length of the spacer tube (T) is about 2 mm. Therefore, there was a problem in that the insertion work was not successful.
