本発明はガラスとの気密封着性と溶接強度を向上したウ
ェルズおよびその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a well having improved airtight sealing properties with glass and welding strength, and a method for manufacturing the well.

続しである。(Prior art) For example, in a 3-part well used for stems of cathode ray tubes, image pickup tubes, etc., an inner lead wire made of nickel-plated iron wire with a larger diameter than the pressed end is welded to one end of a small-diameter Dumet wire press. A rear outer lead wire made of large diameter nickel wire or copper-plated iron wire is welded to the other end.
このような溶接方法は、一般にアークパーカッション溶

ード線やアウターリード線は、電流容量の確保のほか電
極部品の保持や他部品との接続との関係からジュメット
線より太線径のものが使用されている。(Problem to be Solved by the Invention) Since the wells are usually made of different materials and have different coefficients of thermal expansion, it is necessary to achieve airtight sealing with glass and to reduce the amount of distortion, so Dumet wires with the smallest possible diameter are used to suit the usage characteristics. There is. On the other hand, the inner and outer lead wires connected to the Dumet wire are thicker in diameter than the Dumet wire in order to ensure current capacity, as well as to hold the electrode parts and connect them to other parts. .
このように線径差の大きいものを溶接する場合、一般的
には溶接部端面の断面積が小さい側と略同大の溶接部と
なることや溶接部にジュメット線端部表面層の破片が埋
込まれることがあり、このため溶接強度が低下する欠点
がある。When welding wires with a large difference in wire diameter like this, it is common to have a weld that is approximately the same size as the side with a smaller cross-sectional area, or that there are fragments of the Dumet wire end surface layer in the weld. This has the disadvantage that the welding strength is reduced because it may become embedded.
また、アークパーカージョン溶接法は量産性に優れてい

きさが大きくなり、かつスプラッシュ（溶接飛沫）が飛
び易く、ウェルズの取出しに苦慮する欠点がある。Further, although the arc perfusion welding method is excellent in mass productivity, there is a large variation in welding strength. Further, the size of the welding point becomes large and splashes (welding droplets) are likely to fly off, making it difficult to remove the well.
また、抵抗溶接はジュメット線を導電チャックで把持し

が困難になる。In addition, since resistance welding involves holding the Dumet wire with a conductive chuck and applying electricity from the surface of the Dumet wire, it is necessary to remove the electrical insulating layer made of cuprous oxide and borax on the surface of the Dumet wire in advance. There is. Methods for removing this include washing the Dumet wire with hot water or alcohol, or using a special chuck such as a needle to destroy the electrical insulating layer and energizing it. However, if the electrical insulating layer of the Dumet wire is removed or destroyed in this way, air bubbles and bubble lines are generated when the Dumet wire is sealed with the glass member, making it difficult to achieve airtight sealing.
そこで１本発明の課題はガラスとの良好な気密性と溶接
強度とが高いウェルズとその製造方法を提供することで
ある。Therefore, one object of the present invention is to provide a well that has good airtightness with glass and high welding strength, and a method for manufacturing the same.
（課題を解決するための手段）
本発明のウェルズはジュメット線の端部に形成された大
径部の端面にリード線を突合わせ溶接したことによって
溶接部の面積を大きくして溶接強度を向上したものであ
る。(Means for Solving the Problems) In the well of the present invention, the lead wire is butt welded to the end face of the large diameter portion formed at the end of the Dumet wire, thereby increasing the area of the welded part and improving the welding strength. This is what I did.
また、本発明のウェルズの製造方法は中間部を導電性チ

溶接することで、ウェルズを容易に製造できるようにし
たことである。In addition, the method for manufacturing a well of the present invention is to crush the end face of a Dumet wire whose intermediate portion is held by a conductive chuck to increase the diameter of the end of the Dumet wire, and then attach a lead wire to the end face of this large diameter portion. The wells can be manufactured easily by applying current and resistance welding between them and the chuck.
（作 用）
ジュメット線はリード線に比較して線径が小さいが、端
部を膨大させたことによって端面の面積換言すれば溶接
面積が大きくなり、充分な溶接強度が得られる。そして
、仮りに溶接部に多少のジュメット線表面層の破片が埋
込まれて多小強度が下っても要求される溶接強度を保持
できる。(Function) Although the Dumet wire has a smaller wire diameter than the lead wire, by expanding the end portion, the area of the end face, in other words, the welding area becomes larger, and sufficient welding strength can be obtained. Even if some fragments of the surface layer of the Dumet wire are embedded in the welded part and the strength is slightly reduced, the required welding strength can be maintained.
また、ジュメット線の端面を圧潰して大径部を形成する
とき、ジュメット線端部は大径化に伴なって表面層が破
壊されるとともに押し潰され大径化した心線部分が導電

ので、端部を圧潰するとき表面層が破壊されることがな
く、したがってガラス部材と封着したとき、全周面にお
いて良好に溶着し、気密封着ができる。In addition, when the end face of the Dumet wire is crushed to form a large diameter part, the surface layer of the Dumet wire end is destroyed as the diameter increases, and the crushed and enlarged core wire part becomes conductive. It comes in contact with the end face of the chuck and conducts electricity well, allowing good electricity to flow when the lead wire is resistance welded in the first step. Moreover, since the middle part of the Dumet wire is protected by a chuck, the surface layer is not destroyed when the end part is crushed. Therefore, when the Dumet wire is sealed with a glass member, it is well welded on the entire circumferential surface and air is removed. Can be sealed tightly.

It is coaxially molded on the large diameter part (12), (12) of
The surface of the large diameter part (12), (12) has a Dumet wire ω
There is almost no residue of the electrical insulating layer formed on the surface of the wire, and moreover, the entire end face of the large diameter portion is welded to the lead wires (1) and (2).

As shown in the figure, the suppression types (1) and (2) are operated in the direction of approaching each other while cutting off or passing the heating current, and both end faces of the Dumet wire cut piece (13) are strongly pressed and crushed, and the large diameter part (13) is crushed. 12).

る。As shown in the enlarged view of Fig. 4, the Dumet wire (υ) formed in this way was tightly held by the metal cylindrical chuck ■, so the crushing operation However, the triple structure of the core wire (15), the copper coating layer (16), and the surface layer (17) (a glass body made of cuprous oxide Cu, O, and borax) is not destroyed. , since the end part is not protected by the chuck ■, it becomes enlarged by crushing and a large diameter part (12) is formed.In this state, as shown in Fig. 4, the end part is crushed and becomes large diameter part (12). It is crimped onto the end face of the chuck (2), and the part along this end face becomes a flat surface, and the overall shape is approximately drum-shaped.

潰されても表面層（１７）に覆われることがない。Due to this crushing, the surface layer (17) at the end is glassy and therefore has poor spreadability and cannot follow the expansion caused by the crushing, and most of it breaks and falls off. In addition, since the copper coating layer (16) is softer and has higher ductility than the core wire (15), it will break.
Cracks and breaks occur not only in the oxide film portion on the surface but also in most of the copper layer, and the core wire (15) portion is exposed on the surface of the crushed portion. Particularly in the areas that contact the corners and end faces of the chuck (2), the copper layer (16) and the core m (15) directly contact the chuck (2), resulting in good electrical conductivity with the chuck (2). Further, when the end face is cut, the cut surfaces of the core wire (15) and the copper coating layer (16) are already exposed, and even if they are crushed, they will not be covered with the surface layer (17).

The end faces are brought into pressure contact, the switch (2) is turned upward, and a predetermined voltage is applied from the welding power source (2) to resistance weld the Dumet wire (1) and the inner lead wire (2).

By pressing the end faces of the welding wire and turning the switch (2) downward, a predetermined voltage is applied from the welding power source (0), and the outer lead wire (2) is welded to complete the desired well.

部材に封着したとき気密性が良好である。As shown in FIG. 6, the main part of the well obtained in this way is shown in cross section, where the large diameter part (12) of the Dumet wire
Between the end face of the inner lead wire and the end face of the inner lead wire
2) and (2) are mixed to form a mixed layer (2), and the Dumet wire (2) and the inner lead wire (2) are connected via this mixed layer (2). Moreover, the diameter of the large diameter portion (12) is approximately 0.
The diameter of 59 mm approximates the diameter of the inner lead wire (2) of 0.60 na, and the fused layer (3) is formed almost entirely on both end faces, so the welding area is large and the welding strength is sufficiently high. Moreover, since the surface layer (17) covering the surface of the sealing part (11) has almost no peeling, punctures, scratches, etc., it has good airtightness when it is later sealed to a glass member.

い。Moreover, according to the above-mentioned manufacturing method, the Dumet wire cut piece (
13) is pressed and crushed while being gripped with a metal chuck (■), so the surface layer (1) of the sealing part (11) useful for sealing is
7) will not be destroyed. In addition, in the crushing process, both ends of the cut piece (13) are heated to red by the current flowing between the pressing dies (1) and (2) and are easily crushed to form a drum-shaped large diameter part. Moreover, according to this manufacturing method, the large diameter portion (12)
On the end face, the core wire (15) and the copper coating layer (16) are exposed, and there are few or no fragments of the surface layer (17) or copper oxide film, and the side surface of the large diameter part (12) is also exposed. Surface layer (17
) and copper oxide film remain, but only in small quantities, so when the inner lead wire (■) and the outer lead wire (■) are resistance welded, fragments of the surface layer (17) are hardly mixed into the mixed layer (8). Therefore, for this reason as well, the welding strength is high, and even if some residual fragments are present, the strength will not deteriorate much.
また、抵抗溶接に際し、チャック■の端面およびかど部
が直接心線（１５）や銅層（１６）に接触しているので
通電抵抗が小さく、したがって充分に大きい溶接電流が
得られるので上述の大面積の抵抗溶接が良好にできる。In addition, during resistance welding, the end face and corner of the chuck (■) are in direct contact with the core wire (15) and the copper layer (16), so the current conduction resistance is small, and therefore a sufficiently large welding current can be obtained. Good area resistance welding.

調査した。Next, we investigated the mechanical strength of the welded part between the Dumet wire (1) and the inner lead wire ■ in the above-mentioned example, and compared this with the strength of a conventional example of the same size, that is, one without a large diameter part and washed with hot water. compared with. The test consisted of three types: tensile strength and bending strength (repeated left and right bending of 90', passed 10 times or more, failed 9 times or less). Furthermore, the above-mentioned example and conventional example were sealed to a glass member and the leakage rate was investigated.
これらの結果を次表に示す。These results are shown in the table below.

That is, in the well of the present invention, the large diameter portion may be formed by other methods, for example, by applying a copper coating and borax to a core wire having alternating small diameter portions and large diameter portions, and then cutting. The Dumet wire may be formed by using the Dumet wire, in short, it is sufficient that the Dumet wire sealing portion has a large diameter portion with an exposed metal surface at the end surface.Furthermore, welding is not limited to resistance welding.

端側のみを加熱軟化させて抑圧型で圧潰させればよい。The present invention can also be applied to two-part wells. Further, in the case of two-part wells, the manufacturing method is to grip one end of the Dumet wire with a chuck so that no exposed part is exposed, heat and soften only the other end, and crush it with a compression mold.

で、生産性向上にも大きく寄与できる。Furthermore, according to the manufacturing method of the present invention, a long Dumet wire held by a conductive chuck can be cut, crushed at the end, and then welded to a lead wire in succession without changing the grip, thereby improving productivity. It can also make a big contribution.

、したがって気密封着性が良い。As described above, the first claim of the present invention is a well formed by butt welding a lead wire to the end face of a large diameter portion formed at the end of a Dumet wire, which has the advantage of high mechanical strength. . In addition, the method for producing a well in the second claim includes increasing the diameter of the end of the Dumet wire by crushing the end of the Dumet wire, the intermediate portion of which is held by a conductive chuck, so as to destroy the electrically insulating coating layer on the surface of the end. Then, the lead wire is butted against the end face of this large diameter part and resistance welded by applying electricity between it and the chuck, so the surface layer of the sealed part of the Dumet wire is not destroyed, and therefore the airtight sealing property is maintained. good.
また圧潰に際し、チャックの端面ばもちろんかど部がジ
ュメット線に食込んで銅被覆層や心線に接触するので通
電性が良く、良好な溶接が得られ。Furthermore, during crushing, the end face and corner of the chuck dig into the Dumet wire and come into contact with the copper coating layer and core wire, resulting in good electrical conductivity and good welding.
また圧潰に際し大径部側面の表面層の大部分が剥落する
ので溶接に際し表面層の破片が混融層にほとんど混入せ
ず、溶接強度の低下が少ない利点がある。In addition, since most of the surface layer on the side surface of the large diameter part peels off during crushing, the fragments of the surface layer are hardly mixed into the fused layer during welding, and there is an advantage that the welding strength is less reduced.
