The cylindrical wall b of the lid B of the lead-acid battery, which covers and binds the outer peripheral surface, contracts in the direction of the arrow as it cools after molding, and as a result, the upper part of the cylindrical wall b is displaced outward as shown by the chain line. It is often seen that the bushing A peels off from the outer circumferential surface of the upper end, creating a gap C between them. As a result, the electrolyte inside the storage battery tends to leak out through the gap C, and the terminal A
However, it has the disadvantage that it changes color from brown to blackish brown due to the electrolyte, reducing its commercial value. The present invention eliminates such conventional drawbacks and improves the liquid-tightness of the storage battery terminal, that is, the joint between the terminal bushing and the battery lid on the outer periphery of the base 1a of the terminal bushing 1. Among the multiple tiers of tsuba 2, 2..., the second tsuba 2 from the top has a larger diameter 2a than the other tsuba 2.
A battery lid 3 having a cylindrical wall 3a covering all the flanges 2, 2, . . . is bonded to the outer peripheral surface of the base 1a by molding.
本考案実施の１例を添付図面につき説明する。 An example of implementing the present invention will be described with reference to the accompanying drawings.

めて本考案の電池端子部を構成した。 FIG. 2 shows an example of the implementation of the present invention, and 1 shows the lead terminal bushing of the present invention. That is, the terminal bushing 1 has five flanges 2, 2, . The base 1a of the bushing 1 is inserted into a predetermined position of a mold for molding a lid using a conventional method, and molten synthetic resin is poured into the mold, and the lid 3 is liquid-tightly bonded to the outer peripheral surface of the bushing after cooling. The battery terminal part of the present invention was constructed by dressing the battery terminal part of the present invention.
尚、図示のように、該端子ブツシング１の基部

生じない。 As shown in the figure, the connection between the outer peripheral surface of the base 1a of the terminal bushing 1 and the lid 3 is such that the cylindrical wall 3a formed integrally with the lid 3 leaves the upper end surface of the uppermost flange 2 intact. , it is common to wrap and bind the circumferential surface to the lower end surface of the lowermost collar 2. Therefore, when the cylindrical wall 3a contracts in the direction of the arrow during cooling during molding, the downward contraction force from the upper end of the cylindrical wall 3a is particularly exerted by the large diameter flange 2a. Since it is received by the upper surface, the upper end of the cylindrical wall 3a deforms outwards in a conventional manner without any gap therebetween.
このように構成した本考案の端子部をもつ、即
ち埋込式端子を備えた鉛蓄電池蓋を使用し、電池

が認められ、褐色に変化した。 Using the lead-acid battery lid having the terminal portion of the present invention configured as described above, that is, having an embedded terminal, 20 batteries were made, and the same number of batteries were made using the conventional battery lid, As a result of a room temperature storage test for 3 months, the former had no electrolyte seeping into the terminals, while the latter had positive,
Electrolyte seepage was observed in 18 of the 40 negative terminals, which turned brown.

堅牢な端子部を得ることが出来る効果を有する。 In this way, according to the present invention, among the plurality of flanges 2 provided on the outer circumferential surface of the base portion 1a of the terminal bushing 1, the second flanges 2 from the top are replaced with the other flanges 2, 2, . , and the battery cover 3 having a cylindrical wall 3a that envelops all the flanges 2, 2, .
Since the downward contraction from the upper end of the cylindrical wall 3a during molding is prevented by the large-diameter collar 2a, there is no gap during molding unlike in conventional battery terminal parts, and the terminal part is liquid-tight and robust. It has the effect of being able to obtain the following.
