本考案はリード端子付き扁平形リチウム電池に
関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a flat lithium battery with lead terminals.
扁平形リチウム電池は、貯蔵特性がすぐれてい
ることから、最近、電気機器のバツクアツプ用電
源として使用されることが多くなつてきた。この
ような用途においては、本来、電気機器の耐用期

電気機器への組み込みは電気機器の回路基板に電
池をはんだ付けなどで固定することによつて行わ
れる。そのため、はんだ付けなどがしやすいよう
に、電気取り出しを兼ねてリード端子をあらかじ
め電池に取り付けておく必要がある。
Since flat lithium batteries have excellent storage characteristics, they have recently been increasingly used as backup power sources for electrical equipment. In such applications, the battery will not normally be replaced during the life of the electrical device, so it is best to incorporate the battery into the electrical device by fixing the battery to the circuit board of the electrical device using methods such as soldering. It is carried out with Therefore, it is necessary to attach lead terminals to the battery in advance to facilitate soldering, etc., and also to take out the electricity.
このリード端子の取り付けは、電池端子として
の負極端子板や正極缶にリード端子をスポツト溶
接により１本ずつ取り付け、電気機器への組み込
みは、リード端子の先端を電気機器の回路基板に
はんだ付けで固定することによつて行われるの
で、回路基板に取付後の電池は２本のリード端子
で支えられることになる。 These lead terminals are installed one by one by spot welding to the negative terminal plate or positive terminal can used as battery terminals, and to be incorporated into electrical equipment, the tips of the lead terminals are soldered to the circuit board of the electrical equipment. Since this is done by fixing, the battery after being attached to the circuit board is supported by two lead terminals.
ところが、このような回路基板や電池に振動が
かかると、電池を２本のリード端子のみで支えて
いるため、リード端子と電池端子との溶接部分に
剥がれが生じやすい。 However, when such a circuit board or battery is subjected to vibration, the welded portion between the lead terminal and the battery terminal tends to peel off because the battery is supported by only two lead terminals.
しかしながら、そのような剥がれを防止するた
めに、リード端子と電池端子との溶接強度を高く

らず、それによつて、負極側では負極を構成する
リチウムが溶融し、その溶融したリチウムがセパ
レータを通過して正極に達し、内部短絡を引き起
こすおそれがある。 However, if we try to increase the strength of the weld between the lead terminal and the battery terminal to prevent such peeling, welding must be performed with high energy when attaching the lead terminal to the battery terminal. On the negative electrode side, the lithium constituting the negative electrode melts, and the molten lithium passes through the separator and reaches the positive electrode, potentially causing an internal short circuit.
そのため、負極側のリード端子を負極端子板に
高エネルギーで溶接することができず、したがつ
て、負極側のリード端子としては、低い溶接エネ
ルギーでも溶接が可能な薄いものあるいは細いも
のなど、強度の低いものしか使用することができ
ない。 For this reason, the lead terminal on the negative side cannot be welded to the negative terminal plate with high energy. Therefore, the lead terminal on the negative side must be thin or thin, which can be welded with low welding energy, and has high strength. Only those with a low value can be used.
また、それに併せて、正極側のリード端子も負
極側と同様にニツケル細線など強度の低いものが

ところで使用されると、リード端子と電池端子と

池端子から剥がれ、電池が回路基板から離脱する
などの事故が発生する。 In addition, the lead terminal on the positive electrode side is made of a low-strength material such as nickel wire, just like the lead terminal on the negative electrode side, so it cannot sufficiently support the battery after it is attached to the circuit board, and it may be subject to strong vibrations. If the battery is used in a place where a battery is used, strong force is applied to the welded portion between the lead terminal and the battery terminal, causing accidents such as the lead terminal peeling off from the battery terminal and the battery detaching from the circuit board.
本考案は、上述したように従来のリード端子の

The present invention solves the problem of the conventional lead terminal having low strength and the battery detaching from the circuit board due to vibration after being attached to the circuit board as described above. To provide a flat lithium battery with lead terminals that can be strongly attached to a circuit board and whose lead terminals can sufficiently support the battery after being attached to the circuit board.
本考案は、正極側のリード端子を板状のものか

る。
In the present invention, the lead terminal on the positive electrode side is formed from a plate-like material, and its shape is made into a horizontal U-shape consisting of a first horizontal part, a bent part, and a second horizontal part. The first horizontal part is attached to the bottom outer surface of the positive electrode can of the battery by welding, and the tip of the second horizontal part is provided with a hole for inserting a bolt, and the bolt is inserted into this hole and screwed into the second horizontal part. The above object has been achieved by making it possible to fix the part to the circuit board.
本考案において、正極側のリード端子を正極缶

少ない。そして、正極側のリード端子の強度とし
ては、回路基板に取付後の電池を正極側のリード
端子のみで支えることができるように高くしてお
くことが好ましい。 In this invention, attaching the positive electrode lead terminal to the bottom outer surface of the positive electrode can requires welding with higher energy than conventional methods, but the positive electrode has less thermal stability than the lithium that makes up the negative electrode. Because it is in good condition, it is less susceptible to thermal deterioration due to welding. The strength of the lead terminal on the positive electrode side is preferably set high so that the battery after being attached to the circuit board can be supported only by the lead terminal on the positive electrode side.
また、正極側のリード端子と正極缶との溶接強
度は、正極側のリード端子を正極缶から引き剥が
そうとすると、該リード端子や正極缶の底部に変
形が生じる程度にまで高くしておくことが好まし
い。 In addition, the welding strength between the positive electrode lead terminal and the positive electrode can must be made high enough to cause deformation of the lead terminal and the bottom of the positive electrode can when an attempt is made to peel the positive electrode lead terminal from the positive electrode can. It is preferable.

る。 Attaching a strong lead terminal to the positive electrode side as described above naturally requires greater welding energy than conventional welding, but since the positive electrode has better thermal stability than the lithium that makes up the negative electrode, Less susceptible to deterioration. In the example, spot welding between the positive electrode side lead terminal 1 and the positive electrode can 7 was carried out with a stored energy of 50 W.S, a current application time of 2 mS, and a pressure of 2 kg, but no thermal deterioration of the positive electrode was observed. In addition, when conventionally, when using a nickel wire whose tip is compressed into a flat shape as the lead terminal on the positive electrode side in the same way as the lead terminal on the negative electrode side, spot welding to the positive electrode can requires 30 W of stored energy. S, the current application time is 2 mS, and the applied force is 2 Kg, so compared to this, the energy of the present invention is quite high.

Preferably, the lead terminals on the negative electrode side have a diameter of 0.7 to 1.0 mm, and the portion to be subjected to spot welding is compressed and flattened to a thickness of about 0.3 mm. In addition, in the example, a spare terminal made of nickel plate was used for welding the lead terminal on the negative electrode side, but the spare terminal is not limited to this, and may be made of stainless steel plate, nickel plated or tin plated iron plate, etc. Can be used. The thickness of these preliminary terminals is preferably about 0.01 to 0.2 mm.

As explained above, in the present invention, the lead terminal on the positive electrode side is plate-shaped, has high strength, and has an inverted U-shape consisting of a first horizontal part, a bent part, and a second horizontal part. The battery can be firmly attached to the circuit board by inserting a bolt into the hole provided at the tip of the second horizontal part and fixing the second horizontal part to the circuit board with screws. The lead terminals can sufficiently support the battery after it is mounted on the circuit board, improving vibration resistance.
