ネジ端子に関する。[Detailed description of the invention] The present invention relates to a screw terminal for an electrolytic capacitor, in particular, a screw terminal that uses aluminum on the inner side for connecting the lead-out terminal drawn out from the capacitor element, and has a female screw part on the opposite outer side. .

ば第１図に示すように黄銅からなる本体１とアルミニウ
ムからなるリベット部２とからなる。Conventionally, a terminal board is made of a molded product of thermosetting resin such as epoxy, thermoplastic resin such as polypropylene, polyethylene, etc., and the screw terminal embedded and fixed during the molding of the terminal board is, for example, a main body made of brass as shown in Fig. 1. 1 and a rivet portion 2 made of aluminum.

記リベット部２を圧入する穴を形威してあり、数代に前
記リベット部２を圧入して接続していた。The main body 1 has a female threaded portion 3 provided at one end, and a hole formed at the other end into which the rivet portion 2 is press-fitted, and the rivet portion 2 is press-fitted several times for connection.

あった。Screw terminals with such a configuration have problems in appearance, such as when plating the main body 1, the plating solution cannot enter due to residual air in the female screw part 3, leaving incomplete parts in the plating process. In addition, since the connection between the main body 1 and the rivet portion 2 is a press fit between two planes, there is a problem in that contact resistance is large.
本考案は上記の点に鑑みてなされたもので、メネジ部の
メツキネ良をなくし、かつネジ本体とリベット部との接
触抵抗を向上せしめるものである。The present invention has been made in view of the above points, and aims to eliminate the tightness of the female screw portion and improve the contact resistance between the screw body and the rivet portion.
以下図面を参照しながら説明する。第２図に示すように
本体１１はその中心にメネジ部１２を形威し、該メネジ
部１２は本体１１を貫通している。This will be explained below with reference to the drawings. As shown in FIG. 2, the main body 11 has a female threaded portion 12 at its center, and the female threaded portion 12 passes through the main body 11.
該本体１１は例えば銅、アルミニウムまたはこれらの合
金からなり必要によりメツを施す。The main body 11 is made of, for example, copper, aluminum, or an alloy thereof, and is plated if necessary.
そして第３図に示すようにして本体１１のメネジ部１２

スしリベット部１５を形威しネジ端子とする。Then, as shown in FIG.
An aluminum rod is inserted into and pressed with a pair of molds 13 and 14 to shape the rivet portion 15 into a screw terminal.
このようにして作成されたネジ端子は例えば本体１１が
黄銅などからなりメッキを施す場合ニはメネジ部１２が
貫通しているためメネジ部１２の残留空気はないから完
全にメッキ液がゆきわたり不完全メッキ部は全く発生し
ない。For example, if the screw terminal made in this way is made of brass or the like and is to be plated, the female threaded part 12 penetrates through it, so there is no residual air in the female threaded part 12, so the plating solution will not spread completely. Completely plated parts do not occur at all.
また本体１１とリベット部１５との接触抵抗もメネジ部
１２が複雑な表面状態を有するため非常に小さい抵抗値
を得ることができた。Further, the contact resistance between the main body 11 and the rivet portion 15 was able to obtain a very small resistance value because the female thread portion 12 had a complicated surface condition.
メネジ部のメツキネ良について従来との比較を下表に示
す。The table below shows a comparison with the conventional method regarding the tightness of the female thread.

した結果である。The plating is Ni plating, and the conventional example is a screw terminal having the configuration shown in FIG.
This is the result of repeating this process 6 times with 20 pieces each.

FIG. 4 shows the relationship between the contact resistance between the main body and the rivet portion and the standing time when the cycle of leaving for 15 minutes at 00° C.→10° CIEy9 is repeated.
以上の結果から明らかなように本考案になる電解コンデ

く、かつ変化が小さい効果を有するものである。As is clear from the above results, the screw terminal for electrolytic capacitors of the present invention can completely plate the female screw part, and has the effect of having low contact resistance between the main body and the rivet part, and small change. It is.

It can also be used with steel alloys such as.
