BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present invention will be described based on the illustrated embodiments.

FIG. 1 is a plan view of a battery terminal protective sheet according to an embodiment of the present invention, and FIG. 2 is a view showing a state in which the sheet is fitted to a battery terminal. Elements that are functionally the same as those in FIG. 7 are given the same reference numerals.

[0021] The battery terminal protective sheet 5 shown in FIG. 1 has a central hole 51 to be fitted into the electrode post 2 of the battery terminal, and is a circle which is impregnated with protective oil and positioned below the battery terminal fitting 3. It consists of an annular protective sheet 50. The protective sheet 50 is made of a sagable material, here felt. The protective sheet 50 is provided with a cut line 52 in the radial direction at one location on the ring, so that a radial force can be fitted to the electrode post 2.

[0022] The knotter terminal fitting 3 is provided with a winding fitting 30 having a cylindrical winding portion and an open end portion 32 thereof, and a tightening bolt 33 for tightening both open ends in a closing direction. By loosening the attached bolt 33, the winding metal fitting 30 can be slid upward (upper position) along the electrode post 2.

[0023] When the protection sheet 50 is pulled in the radial direction of the electrode post 2 with the battery terminal fitting 3 moved upward (upward position) in this way, the cut sheet 52 becomes a passage and the protection sheet 50 is pulled. Can be extracted from the electrode post 2. At this time, the battery terminal fitting 3 remains connected to the electrode post 2 and, for example, power supply to an on-vehicle electronic device is not cut off.

[0024] When the protective sheet 50 is fitted to the electrode post 2, the battery terminal fitting 3 is

When the protective sheet 50 is pushed inward in the radial direction of the electrode post 2 in the state of being moved to the (upper position), the protective sheet 50 is inserted into the electrode post 2 by being inserted into the cut post 52 and inserted. It is. At this time, the battery one-terminal metal fitting 3 remains connected to the electrode post 2 and power supply to the on-board electronic device is not cut off. [0025] However, since the gap formed after the winding metal fitting 30 is moved upward (upper position) along the electrode post 2 is not so wide, the above-described pull-out and insertion operations, particularly the insertion operation, are relatively troublesome. It is. There is also the problem of electric shock when touching the electrode post 2 directly.

FIG. 3 is a top view of a mounting tool for avoiding this inconvenience, FIG. 4 is a side view, and FIG. 5 is a front view.

[0027] The mounting tool 60 also has a protective material force, and has a U-shaped arm 61 that holds the outer peripheral portion of the protective sheet 50, and a grip 62 that extends from the U-shaped bottom of the U-shaped arm. A groove 63 is provided on the inner side surface of the U-shaped arm 61 so that the outer periphery of the protective sheet 50 can be stored and held on both sides in the diametrical direction. The U-shaped arm 61 has a thickness that can be positioned in the lower gap of the battery terminal fitting 3 moved upward (upward position). In addition, the grip 62 extends obliquely upward from the U-shaped bottom force of the U-shaped arm to the rear end, and is handled during the insertion operation! It ’s easy!

[0028] When replacing the protective sheet 50, loosen the tightening bolt 33 and slide the used terminal sheet 3 upward (upward), and then replace the used protective sheet 50 with the electrode post. Pull 2 outward in the radial direction and pull out at the cut break 52.

Thereafter, as shown in FIG. 3, the outer peripheral portion of the protective sheet 50 is housed in the groove 63 of the U-shaped arm 61 on both sides in the diametrical direction, and the cut break 52 is disposed and held on the front side in the insertion direction. . In this state, the U-shaped arm 61 of the mounting tool 60 is sealed (advanced) in the space below the battery terminal fitting 3, and the protective sheet in the U-shaped arm 61 as shown in Fig. 6 (a). Position 50 in the center of electrode post 2.

[0030] Since the protective sheet 50 is made of a felt felt and has a cut 52 in a radial direction at one annular position, the protective sheet 50 comes into contact with the electrode post 2 in the above-described advancement process. Spreads on both sides of the cut break 52, passes through the electrode post 2 while escaping to both sides of the electrode post 2, and finally surrounds the electrode post 2, that is, a state in which the protective sheet 50 is inserted into the electrode post 2. It becomes.

[0031] After that, when the mounting tool 60 is retracted and the U-shaped arm 61 is extracted from the gap below the battery terminal fitting 3, only the protective sheet 50 is closed due to its flexibility. As a result, the electrode post 2 remains encircled.

Thereafter, as shown in FIG. 6 (b), the battery terminal fitting 3 that has been moved upward (upward position) is returned to the downward direction (downward position), and the tightening bolt 33 is tightened. As a result, the battery terminal protection sheet 5 can be replaced without interrupting the electrical system to the power supply destination of the vehicle or the like.

[0033] The protective sheet may be any sheet as long as a flexible sheet base material is impregnated with protective oil. As the sheet base material, all known electrical protection sheets can be used. For example, a syndiotactic polypropylene layer having a fraction of syndiotactic pentad of 0.7 or more and an MFR of 0.1 to 20 gZlO at 230 ° C. and a layer of cellulose paper are laminated and bonded to each other. An electric protection sheet can be used. Elastic bodies such as butadiene rubber, chloroprene rubber, butyl rubber, and silicon rubber can also be used. As protective oil, mineral oil, silicone oil, polymerized hydrocarbon oil, etc. can be used.
