The base 2 and the cap 3 are fixed in a state where the side wall of the base 2 is in contact with the tip of the protrusion 8. That is, the projection 8 serves as a positioning regulation means for regulating the position where the projection 5 and the opening edge 4 contact each other, and scatters from the projection 5 side to a space portion surrounded by the cap 3 during welding. Alternatively, it also plays the role of a spark intrusion prevention means that blocks intruding sparks. In addition, since the upper portion of the side wall of the base 2 is obliquely cut out, the projection 8 is smoothly guided to a predetermined portion. In addition, the bottom surface of the opening edge portion 4 of the cap 3 may be welded to a flat portion around the base 2 without forming the protrusion 5.

手段としての役割も担っている。In addition to the positioning regulation means, if the positioning is not performed correctly, the protrusion 5 is formed on one side of the contact portion between the protrusion 5 and the opening edge portion 4 so that the protrusion edge 5 is opened. It is known from experience that it is biased to the end of the portion 4 and the protrusion 5 is located at the curved bent portion of the opening edge portion 4 on the other side, and sparks are remarkably scattered during welding at this portion. Has been. Therefore, if the positioning is performed correctly, it is possible to suppress sparks from scattering, and the positioning restriction means also plays a role as a suppression means of spark generation during welding.

In the figure, first, as shown in FIG. 2A, the inner wall of the cap 3 is thinly cut off by a cutting blade 200. As a result, since the tip of the cutting blade 200 has an inclined portion, the inner wall portion of the cap 3 contacting the inclined portion forms an inclined portion that spreads downward. Then, the peripheral edge portion of the cutting blade 201 is put under the inclined portion, and the inclined portion is gradually raised to form the protrusion 8 therein. The cutting blade 200 and the cutting blade 201 are, for example, of an oval type having a flat surface corresponding to the opening of the cap 3, and the cutting blade 200 and the cutting blade 2 are provided in the opening.

In this embodiment, a step portion 6 is provided around the inner wall of the cap 3, and the step portion 6 is made of synthetic material such as polystyrene, ebonite, styrofoam, bakelite, etc., which is fitted from the opening of the cap 3. A part of the ring piece 7 made of resin is in contact. The ring piece 7 may be dimensioned so as to be crimped to the inner wall of the cap 3. Further, instead of the ring piece 7, a ring of rubber or soft plastic may be fitted into the upper portion of the base 2. In that case, the step 6 on the inner wall of the cap 3 need not be provided. When a voltage is applied between the cap 3 and the base 2, the ridges 5 are melted and welded to the bottom surface of the opening edge portion 4 of the cap 3 to be melted.
And the base 2 are fixed. At that time, even if a spark is generated, it is prevented by the ring piece 7, so that it is possible to prevent the molten metal from adhering to the terminal pin or the like. It should be noted that the ring piece 7 can also serve as a positioning regulating means for regulating the position where the protrusion 5 and the opening edge portion 4 contact each other, as in the case shown in FIG.

In the electronic component case 1 of this embodiment, a step portion 9 is provided around the inner wall of the cap 3, and an extremely narrow gap (about 0) is provided between the inner wall of the portion below the step portion 9 and the side wall of the base 2. A space of about 0.02 mm is provided so that the cap 3 can be fitted to the base 2. The step portion 9 is provided a little higher than the illustrated state, that is, when the length of the inner wall below the step portion 9 is increased and the welding of the base 2 and the cap 3 is completed. The stepped portion 9 may be in the illustrated state. Since the gap is extremely narrow, sparks during welding cannot pass through. Therefore, it plays a role of a spark invasion preventing means for preventing a spark from invading the space surrounded by the base 2 and the cap 3.

Ribs 10 and 10 for keeping the gap between the side wall of the base 2 and the inner wall of the cap 3 substantially constant at four locations on the side wall of the
10 and 10 are formed. The gap between the inner wall of the cap 3 and the side wall of the base 2 is about 0.
It is set to 02 mm to 0.065 mm. Rib 1
0, 10, 10 and 10 serve as positioning regulating means for regulating the position where the protrusion 5 and the opening edge portion 4 come into contact with each other. If this positioning is not performed correctly, the protrusion 5 On one side of the contact portion between the opening edge 4 and the opening edge 4, the protrusion 5 is biased toward the end of the opening edge 4 of the cap 3, and on the other side the protrusion 5 bends the opening edge 4. It is known from experience that it comes to be located at the bent portion, and sparks are significantly scattered at the time of welding at this portion. Therefore, if the positioning is performed correctly, it is possible to suppress the scattering of sparks, and further to provide a product in which the appearance is not impaired. The rib 10 is formed on an inclined surface which becomes thinner from bottom to top in order to facilitate the introduction of the cap 3 into the rib 10. The ribs 10 may be provided only at three places. Also, two arcuate portions may be provided on the left and right sides.
