一般的である。2. Description of the Related Art Generally, a lead storage battery terminal is formed by welding only a lead bushing, which is previously inserted into a lid and molded, and a tip of a pole. A conventional example of such a lead bushing is shown in FIG. The illustrated lead bushing 1 is a lead bushing widely used in lead acid batteries for automobiles, and includes a taper portion 4, a collar portion 5 and an insert portion 6, and a lid portion 3 in which the collar portion 5 and the insert portion 6 are embedded. . The tapered portion 4 is a portion that comes into contact with the connector of the automobile after the terminals are formed. Since the outer diameter of the terminal is defined in JIS, the outer diameter of the tapered portion 4 is also defined. On the other hand, the insert portion 6 is provided with a ring-shaped step and a rib so that the terminal does not rotate against an external force such as a torque received when connecting the connector of the automobile, and the outer diameter is increased. Improves torque resistance. Therefore, the outer diameter of the insert portion 6 is generally larger than the outer diameter of the tapered portion 4.

にもなっていた。As described above, the outer diameter of the insert portion 6 may be increased to improve the torque resistance. However, since the outer diameter of the tapered portion 4 is determined, increasing the outer diameter of the insert portion 6 not only creates a thick wall portion in the insert portion 6 but also causes a difference from the wall thickness of the tapered portion 4 to cause the casting such as burns. Cause defects. Therefore, measures such as lengthening the insert portion 6 or providing ribs have been taken, but not only the casting of the lead bushing is lowered, but also the height dimension of the battery is regulated, which leads to reduction in battery size. It was also a neck.

The outer diameter and inner diameter of the lower end of the lead is 150% or more of the outer diameter and inner diameter of the upper end, respectively, and the inner circumference of the hollow cylindrical portion of the lead bushing has an inclination of 30 ° or more and an inclination of less than 20 °. Are provided in the form of strips in the vertical direction, and the ratio of the lengths of the respective arcs is set to approximately 2: 1 at the upper end of the slope.

る。With this structure, the outer diameter of the lower end portion of the lead bushing, that is, the insert portion can be set to 150% of the outer diameter of the upper end portion, that is, the taper portion, and the torque resistance is significantly improved. On the other hand, since the cylindrical hollow portion of the collar portion is provided with an inclination of 30 ° or more, the inner diameter of the cylindrical hollow portion of the insert portion suddenly increases, which not only prevents the thick portion from occurring in the insert portion but also the difference in the thickness from the taper portion. Can be kept low. Here, a pole is inserted into the hollow cylindrical portion of the lead bushing when the battery is assembled. If the center of the lead bushing deviates from the center of the pole column during insertion, the tip of the pole column rises while contacting the hollow cylindrical portion of the lead bushing. If there is an inclination of 20 ° or more in the hollow cylindrical portion, the tip of the pole column will be caught in the inclination,
Not only the poles are bent significantly, but also the electrode plates are crushed, resulting in defective battery assembly. However, in the present invention, 3
Since the inclination of 0 ° or more and the inclination of less than 20 ° are provided,
The poles rise smoothly while contacting an inclination of less than 20 °. It is suitable that the ratio of the lengths of the arcs with an inclination of 30 ° or more and the inclination of less than 20 ° is approximately 2: 1 at the upper end of the inclination.
If the ratio of inclination of 30 ° or more is smaller than this, a thick portion is generated, and if it is larger than this, the pole column cannot be smoothly raised.

要がなく電池小型化に貢献している。FIG. 1 is a sectional view showing a state in which a pole 2 is inserted into a lead bushing 1 in a lead storage battery terminal of one embodiment. The lead bushing 1 includes a tapered portion 4, a collar portion 5 and an insert portion 6, and the lid portion 3 has the collar portion 5 and the insert portion 6 embedded therein. The outer diameter of the tapered portion 4 is determined as described above. In the JIS thin cathode terminal of this embodiment, the outer diameter of the upper end portion is φ15.9 mm, and the inner diameter is φ10 mm.
Is. On the other hand, the outer diameter of the insert portion 6 is 27 mm and the inner diameter is 17 mm. In the present embodiment, the outer diameter and inner diameter of the lower end portion of the lead bushing 1 are 170% of the outer diameter and inner diameter of the upper end portion, respectively, but if it is 150% or more, sufficient torque resistance can be obtained. Since the inclination 7 of 34 ° is provided on the inner circumference of the cylindrical hollow portion of the collar portion 5, the inner diameter of the cylindrical hollow portion of the insert portion 6 suddenly increases. Therefore, the difference in wall thickness between the taper portion 4 and the insert portion 6 is small, and the shape is excellent in castability because there is no thick portion, and it is not necessary to extend the length of the insert portion to improve the torque resistance, and the battery is small.

The pole 2 rises smoothly while contacting the inclination 8 of 17 °. Here, if the inclination 7 is not more than 30 °, a thick portion will be formed in the collar portion 5 and the insert portion 6, while on the other hand, if the inclination 8 is less than 20 °, the pole column cannot be smoothly raised.

値は大なるものがある。INDUSTRIAL APPLICABILITY As described above, the lead acid battery terminal of the present invention can mold lead bushings without causing casting defects such as burns, and is resistant to external forces such as torque received when connecting an automobile connector. It is also very popular. In addition, the length of the lead bushing insert can be shortened, which contributes to downsizing of the battery. In addition, it is possible to prevent the bending of the pole column and the bending of the electrode plate group when the pole column is inserted into the lead bushing. Its industrial value is enormous.
