Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a battery case. When inserting or removing a battery case from a charger, an unused charger terminal can be used to It is designed to prevent scratches from occurring on the parts.

(Prior Art) A battery case 1 with a built-in rechargeable battery as shown in FIG. 5 is inserted into a box-shaped charger 2 as shown in FIG.
The battery case 1 is charged through terminals 5a and 5b on the battery side that are in contact with terminals a and 4b.

The charger 2 is designed to be compatible with a plurality of other battery cases (not shown) in which terminals are provided at positions different from, for example, the terminal 5b on the battery side of the battery case 1 illustrated in FIG. , a plurality of terminals (in the illustrated example, two charger terminals 4b and 4c)
), and these charger terminals 4a, 4
The contact portions T of b and 4c are made to protrude sufficiently largely from the inner surface 2a of the charger 2.

(Problem to be solved by the invention) As mentioned above, the charger terminals 4a, 4b,...
protrudes sufficiently from the inner surface 2a of the charger 2, so that when the battery case 1 is inserted, the charger terminal, which is unnecessary for the battery case 1, comes into contact with the outer part of the battery case 1. .

For example, in the battery case 1 shown in FIG. 5, when inserting or removing the battery case 1, especially the left and right outer portions of the contact portion T of the charger terminal 4c shown in FIG. position A by the edge of
There was a problem that scratches were easily formed near the area as shown in the figure.

(Means for solving the problem) This invention is an attempt to solve the above-mentioned conventional problem that the charger terminal, which is unnecessary for the battery case, scratches the outside of the battery case. The charger 2 is a battery case with a built-in rechargeable battery, and is provided with charger terminals 4a, 4b, . . . in correspondence with multiple types of battery cases with different terminal positions. In a battery case inserted into a battery case, a rib 8 is provided protruding from the outside of the battery case 6 so that it can come into contact with a contact portion T of a charger terminal 4c which is unnecessary for the battery case to be inserted.

(Function) When the battery case 6 is inserted into the charger 2, the contact portion T of the charger terminal 4c, which is unnecessary in this case, comes into contact with the rib 8 provided on the battery case 6. Contact between the outer part of the battery case 6 and the charger terminal 4c is prevented, and there is no possibility of scratches caused by contact.

(Example) Next, an example of this invention will be described based on the drawings.

Battery case 6 illustrated as a perspective view in FIG.
When the battery case terminals 7a and 7b are provided and inserted into the charger 2, as shown in FIG. 4, the battery case terminal 7b is connected to the positive polarity charger terminal 4b, and
The structure is such that the battery case terminal 7a is in contact with the negative polarity charger terminal 4b, respectively.

In the inserted state, a rib 8 is provided on the outside of the battery case 6 at a position corresponding to the charger terminal 4c, which is unnecessary for the battery case 6. 4c contact part T
(The part that comes into contact with the terminal of the battery case, not shown, which will be charged by this charger terminal 4c)
As is clear from FIG. 3, this rib 8 extends to the corner of the lower surface of the battery case 6, and the lower part is formed into a thin slope shape. is forming.

Therefore, when this battery case 6 is inserted into the charger 2, the battery case terminals 7a and 7b come into sliding contact with the charger terminals 4a and 4b, respectively, and the unnecessary charger terminal 4c is inserted into the rib of the battery case 6. 8, this unnecessary charger terminal 4c no longer comes into contact with the outer side of the battery case 6.

(Effect of the invention) Since the battery case according to this invention is constructed as described above, when the battery case 6 is inserted into the charger 2, the ribs 8 provided on the battery case 6 and the ribs 8 that are unnecessary in this case are removed. The contact portion T of the charger terminal 4c that is in contact with the battery case 6 is prevented from coming into contact with the charger terminal 4c, and the fear of scratches due to contact is eliminated.
