ン層７とを溶接するものである。Generally, a metallized plastic film capacitor of this type (hereinafter simply referred to as a capacitor) has electrodes 2 and 3 formed at both ends of a capacitor body 1 as shown in FIG. 5 is designed to be welded. That is, a zinc layer 6 is formed on both ends of the capacitor body 1 so as to be electrically connected to an internal metal vapor deposition film, a solder metallikon layer (metal spraying) 7 is further formed, and lead wires 4 and 5 are welded to the solder metallikon layer 7. To do. Conventionally, the welding of the lead wires 4,5 to the electrodes 2 and 3 is performed by applying the base ends of the lead wires 4,5 to the electrodes 2 and 3, respectively, as shown in FIG. Two pressure electrodes 8-11 made of chrome copper or the like are pressed at a constant pressure with two electrodes each, and welding power sources 12, 13 and transformers 14, 15 are interposed between the paired pressure electrodes 8-11, respectively. The impulse electrodes 8 and 9 and the pressure electrodes 11 and 12 forming a pair.
The lead wires 4 and 5 and the solder metallikon layer 7 are welded by Joule heat generated between them.

いった問題がある。However, in the above conventional method and device, the electrodes 2, 3
If there is unevenness on the surface of the solder metal solder layer 7
Due to non-uniformity of the thickness of the lead wires 4 and 5, the distance between the lead wires 4 and 5 is not constant, and as shown by the chain double-dashed line in FIG.
However, there was a situation in which it was inadvertently expanded. Moreover, since the pressure electrodes 8 to 11 forming a pair press the lead wires 4 and 5 by separate and independent pressurizing mechanisms, it is not easy to set each pressurizing force to be constant, and the pressurizing electrodes 8 to 11 are not easy to apply. Even if the structure of the pressure mechanism is complicated and even if the pressure mechanism can be made uniform, if the solder metallikon layer 7 has irregularities or has uneven thickness, the contact resistances of the respective layers will vary and the welded state will also be maintained. A situation occurs in which the lead wires 4 and 5 unintentionally spread as shown by the two-dot chain line in FIG. In addition, as described above, the welding state is not constant and uneven, and especially when the melting depth of the solder metallikon layer 7 is deep, the metal vapor deposition film in the capacitor body 1 may be damaged. There is a problem that a double structure in which a zinc layer 6 having a metal melting temperature difference is interposed as a stopper for preventing this damage between the solder metallikon layer 7 and the solder metallikon layer 7 is required.

損なうような加熱をさせることがない。Next, the lead wire welding method of the metallized plastic film capacitor having the above structure and the operation of the apparatus will be described. First, as shown in FIG. 1, the clip body 24 holds the capacitor body 21 which is put into a predetermined position. When the capacitor body 21 is clamped by the clip 24, the center of the capacitor body 21 is always clamped so that the holding position of the clip 24 does not change every time the capacitor body 21 is clamped. Next, the clamp mechanism that also serves as the auxiliary electrode
Is a retracting position with respect to the capacitor body 21 sandwiched by the clip 24, the receiving seats 33, 34 perform an opening operation by the opening / closing mechanism 47, perform a closing operation after receiving the lead wires 22, 23,
The lead wires 22 and 23 are securely held so as not to swing. After that, the air cylinder 31 is used for each auxiliary electrode and the clamp mechanism.
27, 28 are moved toward the capacitor body 21 until they abut the stopper 36. When the auxiliary electrode / clamping mechanisms 27, 28 collide with the stopper 36, the lead wires 22, 23 held between the seats 33, 34 are pressed against the connection points 25, 26 of the capacitor body 21. That is, the position where the auxiliary electrode / clamping mechanism 27, 28 abuts the stopper 36 is further inside the connection points 25, 26 than the position where the lead wires 22, 23 contact the surface of the connection points 25, 26 of the capacitor body 21. It is set in a position where it goes in. At this time, since the main electrodes 37, 38 and the seats 33, 34 are not energized, the connecting portion of the capacitor body 21 is not in a molten state, so that the stopper 36 and the auxiliary electrode clamping mechanism are not melted. The lead wires 22 and 23 are connected to the capacitors 25 and 26 at the connection points 25 and 26, respectively, by a value commensurate with the distance between the contact positions with the 27 and 28 and the surfaces of the connection points 25 and 26 of the capacitor body 21.
A pressing force acts on. After that, the air cylinder 43
The main electrode moving mechanism 39, 40 is moved toward the capacitor main body 21 by means of the main electrodes 37, 38 to press the ends of the lead wires 22, 23 pressed against the connection points 25, 26 of the capacitor main body 21. . This pressing force can be arbitrarily set by adjusting the elastic force of the spring 44, but the lead wires 22 and 23 are connected to the capacitor body 21 by the abutment of the auxiliary electrode / clamp mechanism 27, 28 with the stopper 36. Since the pressing force is applied to the points 25 and 26, it is not necessary to apply a very large pressing force, and the lead wires 22 and 23 are connected to the contact points 25 and 26 of the capacitor body 21.
It is enough to press it down. Next, impulse power as welding power is received from the power transformers 35 and 46 to the seat 33,
It is provided between 34 and the main electrodes 37 and 38. Seats 33, 34 and main electrode
When impulse power is applied between 37 and 38,
Between the main electrodes 37 and 38 and the main electrodes 37 and 38, Joule heat is generated in the portions of the lead wires 22 and 23 to melt the solder metallikon layer at the connection points 25 and 26 of the capacitor body 21, and as a result, the lead wires 22 and 23.
Is welded to the connection points 25 and 26 of the capacitor body 21. At this time, the lead wires 22 and 23 are connected to the auxiliary electrode clamp mechanism 27 and 28.
The lead wires 22 and 23 are connected to the connection points 25 and 26 of the capacitor body 21 which are applied at the time of the initial collision between the stopper wire and the stopper 36, and the lead wires 22 and 23 are connected to each other as shown in FIGS. As shown in FIG. 5, it digs into the connection points 25 and 26 of the capacitor body 21. This bite amount is the same as the clamping mechanism 27,2
This corresponds to the amount of pressing force that acts on the initial collision between 8 and the stopper 36. As shown in FIG. 3, the stopper 36 abuts against the auxiliary electrode / clamping mechanism 27, 28 such that the lead wires 22, 23 are always positioned at a distance O from the center of the capacitor body 21. Therefore, when the lead wires 22 and 23 are welded to the welding points 25 and 26 of the capacitor body 21, the lead wires 2 and
The pitch P between 2 and 23 is the clamping mechanism for each sub electrode 27, 28
Is equal to the distance between the stoppers 36 at the position where they abut against each other, and thus is always constant. Moreover, even if the pressing force of the main electrodes 37, 38 against the lead wires 22, 23 is somewhat unbalanced, or if the connection points 25, 26 have irregularities, they are mainly used as the auxiliary electrode / clamp mechanism 27, 28. Stopper 36
It is regulated by the pressing force of the lead wires 22 and 23 to the connection points 25 and 26 that acts at the time of welding before welding with, and the lead wires 22 and 23 are not swingable and rattled by the catches 33 and 34. By reliably sandwiching the lead wire, unlike the conventional example shown in FIG. 7, there is no problem that the lead wire is inclined and welded. In the welding method as described above, the lead wires 22 and 23 are connected to the capacitor body 2 by Joule heat by supplying impulse power.
Since it is welded to the connection points 25, 25 of 1 by instantaneous heating,
It is possible to obtain a welding state which is constant at a high speed, and is not heated so as to impair the electrical characteristics of the capacitor body 21 as the welding speed is increased.

用上頗る有益である。As described above, according to the lead wire welding method and apparatus for a metalized plastic film capacitor of the present invention,
Even if there is unevenness on the electrode surface that is the connection point of the metallized plastic film capacitor body, the welding state of the lead wire is always constant and no unevenness occurs, and only the main electrode presses against the lead wire. It is sufficient to clean and maintain only the main electrode, and moreover, the interval between the lead wires welded to both ends of the metallized plastic film capacitor body is constant, and it is possible to maintain stable quality.
This is extremely convenient when mounting on a printed wiring board using an automatic loading device. Furthermore, unlike the conventional method, the connection point of the capacitor body to which the lead wire is welded can perform stable heating of the lead wire and instantaneous heating, so a sufficiently good welded state can be achieved only with the solder metallikon layer without the zinc layer. Obtainable. Further, it is possible to speed up the welding of the lead wire to the metallized plastic film capacitor body, which is very useful in use.
