偏平形電池に関するものである。[Detailed description of the invention] <Industrial application field> This invention relates to the improvement of a board-mounted type flat battery with lead terminals. The present invention relates to a flat battery with a lead terminal in which the terminal is fixed and two lead terminals thereof are substantially parallel and protrude in substantially the same direction.

などとして使用されている。《Prior art》 Batteries with lead terminals are often used in non-aqueous electrolyte batteries such as lithium batteries, which have a high energy density.By soldering or screwing the lead terminals, batteries with lead terminals can be attached to circuit boards of electronic devices. It is used as a memory backup power supply, etc.

付けられている。 There are various types of batteries with lead terminals, one of which is a flat type battery with lead terminals as exemplified in FIG. 1. A flat positive electrode can 10, a negative electrode terminal plate 12, and an annular sealing gasket interposed between them (not shown)
A battery case is constructed, and a lead terminal 14 made of an elongated metal plate is spot welded to the bottom surface of the positive electrode can 10, and a similar lead terminal 16 is also spot welded to the negative electrode terminal plate 12. These two lead terminals 14 and 16 protrude in substantially the same direction relative to the battery case and are attached substantially parallel to each other.

口端縁部分とが非常に近接しているため、リード
端子１６が少し下方へ曲げられると直ぐに正極缶
１０の開口端縁に接触してしまう。 For flat batteries with lead terminals like the one above,
There is a problem in that short circuits due to the lead terminals 14 and 16 are likely to occur during the process from manufacture to mounting on a circuit board. In particular, negative terminal plate 1
Since the base of the lead terminal 16 on the second side and the opening edge of the positive electrode can 10 are very close to each other, when the lead terminal 16 is bent slightly downward, it immediately contacts the opening edge of the positive electrode can 10. Put it away.

のが公知となつている。 In order to prevent this contact, in conventional batteries of this type, a heat-shrinkable tube is attached to the terminal edge of the battery case to provide an insulating coating. Alternatively, the sealing gasket is made to protrude from the open edge of the positive electrode can 10, and the protruding portion insulates and separates the lead terminal 16 from the open edge of the positive electrode can 10. Alternatively, as shown in Japanese Utility Model Application Publication No. 57-69159, a part of the lead terminal, that is, a part of the lead terminal facing the end of the outer can, is covered with a heat-shrinkable tube. It's summery.

の直接的な接触に対する対策も必要である。<<Problems to be Solved by the Invention>> However, none of the conventional insulation structures can prevent a short circuit accident caused by the tip portions of the lead plates 14 and 16 coming into contact with each other. Direct contact between lead terminals 14 and 16 is
The thinner the battery and the smaller the distance between the terminals, the easier it is to wake up, and the longer the lead terminals 14 and 16 or the more flexible it is, the easier it is to wake up. Considering the process of mounting electronic components, it is highly anticipated that force will be applied to the lead terminals 14 and 16 during the handling and transportation process of flat batteries with lead terminals. Measures against direct contact between people are also necessary.

される。 The above problem can be dealt with by changing the protruding direction of the two lead terminals or by bending the lead terminals so that the two terminals do not come close to each other. However, the form of the lead terminals and their positional relationship can also be determined depending on the user's factors, so it is also necessary to have two lead terminals that are almost parallel and protrude in the same direction, as shown in Figure 1. .

ことにある。 The purpose of this invention is to provide a flat battery in which two lead terminals are installed in parallel and projecting in the same direction, with a simple insulation structure, and by contacting between the lead terminal and the positive electrode and between the lead terminals. The purpose is to prevent both short-circuit accidents.

樹脂にて塗膜を形成してなるのである。《Means for solving the problem》 In order to achieve the above purpose, in this invention,
In a flat battery with lead terminals, in which lead terminals are fixed to both terminal surfaces of a flat battery case, and the two lead terminals protrude in substantially parallel directions, at least The entire protrusion is melted, separated, and peeled by the heat of soldering, and a coating film is formed of an insulating resin that can be soldered.

付けを行うことができる。《Operation》 Even if the lead terminals come into contact with each other for some reason, there will be no short circuit because the entire lead terminal protruding from the battery case is coated with an insulating resin. There is no. Furthermore, during use, the coating film melts, separates, and peels off due to the heat of soldering, so that soldering can be performed in the same manner as in the conventional method.
《実施例》

突出している。 Similar to the one in FIG. 1, a lead terminal 14 is spot welded to the bottom of the positive electrode can 10, and a negative electrode terminal plate
A lead terminal 16 is spot-welded to 2, and these lead terminals 14 and 16 are approximately parallel and protrude in approximately the same direction.

PEを硬化させる。 In this embodiment, the entire surface of this flat battery with lead terminals is covered with an insulating film 18 made of a low melting point resin. As the resin material of the insulating film 18,
PVA (polyvinyl alcohol), PE (polyethylene), etc. are suitable. Further, in order to cover the entire surface of the flat battery with lead terminals with the insulating film 18, a spraying method or a dipping method is suitable. For example, a 4% aqueous solution of PVA is sprayed onto a flat battery with lead terminals, or the flat battery with lead terminals is immersed in this aqueous solution and taken out, and the PVA solution is dried.
When using PE, a flat battery with lead terminals is immersed in molten PE, taken out, and cooled.
Harden the PE.

にはその先端まで全面的に絶縁被覆が形成されて
いるため、保存中のハンダ付け部の腐食によるハ
ンダ付け性の劣化を防ぐこともできる。 In the flat battery with lead terminals in which the insulating film 18 is formed on the entire surface as described above, a short circuit does not occur even if the lead terminals 16 contact the open edge of the positive electrode can 10, and the lead terminals 14 and 16 do not cause a short circuit. Direct contact will not cause a short circuit. When this flat battery with lead terminals is mounted on a board and soldered, the insulating film 18 at the tips of the terminals 14 and 16 easily melts or decomposes due to the heat during soldering.
After peeling off, the metal surfaces of the terminals 14 and 16 are exposed and soldering can be performed without any problem. Moreover, since the lead terminal is entirely coated with an insulating coating up to its tip, it is possible to prevent deterioration of solderability due to corrosion of the soldering part during storage.
ところで、この種の電池における短絡事故は、

である。従つて、上記の実施例のようにリード端
子つき偏平形電池の全表面に絶縁皮膜１８を形成
する必要は必ずしもない。 By the way, short circuit accidents in this type of battery are caused by
As mentioned above, this is mainly caused by the contact between the lead terminal 16 and the opening edge of the positive electrode can 10 and the contact between the lead terminals 14 and 16.
Insulating film 18 on the protruding part from the battery case 16
If it is formed, it is effective to prevent short circuit accidents. Therefore, it is not necessarily necessary to form the insulating film 18 on the entire surface of the flat battery with lead terminals as in the above embodiment.

来同様にハンダ付けすることができる。<<Effects of the invention>> As explained in detail above, this invention is extremely effective in forming a coating film of insulating resin on at least the entire protrusion of the lead terminal from the battery case by spraying or dipping. By adding a simple process, it is possible to realize a flat battery with lead terminals that is free from short-circuit accidents. In addition, the coating film melts, decomposes, and peels off due to the heat of soldering, and is made of an insulating resin that can be soldered. Therefore, the lead terminal board of the battery of this invention can be soldered in the same way as before. I can do it.
