Similarly, reference numeral 5 denotes a cathode having a lead-cylinder wall integrally formed on the inner peripheral surface of the center pole insertion hole, which is formed integrally with and protrudes upward from the lid surface similarly to the anode pole terminal seat. A pole terminal seat is shown, through which a cathode pole is inserted and which is fused and held to the lead cylinder wall. Reference numeral 6 denotes an anode pole terminal formed at the center of the upper surface of the anode terminal seat 4, and reference numeral 7 denotes a cathode pole terminal formed at the center of the upper surface of the cathode terminal seat 5.

[0007] The structure of the above battery is the same as that of the conventional battery. According to the present invention, in order to provide a polarity display device for displaying the polarity of the anode post terminal 6 or the cathode post terminal 7 of the battery, at least one of the polarity display rings of the present invention described later is provided at the terminal seat. The polar display device of the pole terminal according to the present invention can be configured by a simple operation of merely fitting to the terminal.

In general, the polarity display ring of the present invention, which is colored red, is used to indicate the polarity of the anode post terminal. When the polarity display of the cathode pole terminal is performed, a polarity display ring of the present invention which is colored other than red, for example, white is used.

In order to construct the polarity display device of the pole terminal of the present invention, for example, a polarity display ring 8 having a shape as shown in FIGS. It is produced by melt molding. As shown in FIG. 3, the ring 8 is opened by providing a slit 8a having a width of 1 mm, for example.
A polar display made of polypropylene molded on an annular space forming surface 8b consisting of a downwardly inclined surface connecting the upper surface and the lower surface on its inner periphery, with a height of 3 mm, a width of the upper surface of 2 mm, and a width of the lower surface of 0.5 mm. It is a ring. The ring 8 is usually made into a red color by mixing a red colorant for anodic display, and if necessary, an organic or inorganic fluorescent pigment or the like is added to the synthetic resin material. A desired fluorescent agent is mixed and melt-molded to form a material whose polarity can be recognized even at night. Thus, the polarity display ring 8 of the present invention is manufactured as a flexible ring that can be easily opened and expanded with a small external force, as shown by the phantom line in FIG. Therefore, the molded ring made of the one mold provides versatility that can be fitted to each of the anode pole terminal seats of two or more types of batteries having different diameters of the anode pole terminal seats. Each time the diameter is different, there is no need to make a mold for forming a pole for display

[0010] The inner diameter D ₁ dimension of polar display ring 8 in advance, it is preferable that this is equal to or diameter of the outer peripheral surface of the anode pole terminal seat 4 of the battery to be fitted to form it from a slightly smaller diameter . For example, when the diameter of the FIG. 2 shows the battery 1 of the anode column terminal seat 4 is 25mm, it is preferable to form the inner diameter D ₁ thereto slightly less than 24.5 mm. Thus, as shown in FIG. 1 and FIG.
When fitted to the anode terminal seat 4, a holding force for firmly holding the terminal seat 4 is generated on the ring 8, and a stable and good fitted state is obtained.

The above-described anode post terminal seat 4
Since the red anode display ring 8 fitted to the terminal protrudes in a red ring shape from the entire peripheral surface of the anode post terminal seat 4, the mark protrudes from the terminal seat 4 provided with the red ring.
It can be easily viewed from any direction that pole terminal shown in issue 6 is an anode pole pin. The ring 8
Although a relatively narrow product as shown in the figure is sufficient and the manufacturing cost can be reduced, the present invention is not limited to this, and it is a matter of course that a wider plate-shaped molding ring may be used.
Further, since the ring 8 is located at the position where the ring 8 is fitted to the pole terminal seat 4, there is an advantage that the ring terminal 8 does not hinder the attachment of a harness or the like to the anode terminal 6.

Further, according to the present invention, as shown in FIG. 3, the polarity display ring 8 has a space forming surface 8b formed of an obliquely downwardly inclined surface formed on the inner periphery thereof. In the state in which the liquid crystal device 1 is fitted to the anode post terminal seat 4, as shown in FIG. 2, the capillary action of the liquid is caused between the peripheral surface of the terminal seat 4 and the space forming surface 8b of the ring 8. A space 9 consisting of a cut annular space is formed,
Even if water or electrolyte spilled on the upper surface of the terminal enters from between the terminal seat 4 and the surface of the lid 3, the capillary action is cut off by the space 9. increases the surface, so that the reach pole terminal 6 projecting at the center of the upper surface of the terminal seat 4 is prevented, deterioration in quality due to oxidation by water or electrolytic solution of the pole terminals 6, the performance The drop can be prevented. .

FIG. 4 shows a modification of the present invention. That is, after manufacturing an annular molded product having a triangular cross section, a part thereof is simply cut transversely to form a slit 8a 'to show the polarity display ring 8'. 8b '. When this is fitted to the anode pole terminal seat 4, an annular space 9 ′ having a triangular cross section is formed between the terminal space 4 and the peripheral surface of the terminal seat 4.

FIG. 5 shows still another modification, in which the ring 8 "is formed with a space forming surface 8b" having an L-shaped cross section at the lower portion of its inner peripheral surface. 4, a space 9 ″ is formed between the peripheral surface of the terminal seat 4 and the space forming surface 8 b ″ having an L-shaped cross section on the inner periphery of the ring 8 ″. It is intended to be squeezed.

In the above embodiment, the case where the anode display ring is fitted to the anode post terminal seat is shown. For example, a cathode display ring formed in the same manner as described above except that it is colored white is manufactured. Then, it is a matter of course that the cathode display device of the present invention may be configured by fitting this to the pole terminal seat 5 of the cathode pole terminal 7.

[0016]
