In the description of the present application, "a plurality" means two or more unless otherwise specified.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

A battery assembly structure, as shown in fig. 1-3, comprising: the installation shell 100, the space that constitutes on the installation shell 100 to be used for the dry battery assembly is provided with the position of bone 120 that is used for the spacing of dry battery on the space.

A positive electrode terminal 200 and a negative electrode terminal 300 are provided in the space where the dry battery is mounted, and the positive electrode terminal 200 and the negative electrode terminal 300 are inserted into the mounting case 100. Because the dry battery is provided with the anode and the cathode, the anode needs to be connected with the anode terminal 200 during assembly, and the cathode needs to be connected with the cathode terminal 300 to complete electrical communication.

Therefore, the reverse mounting prevention plate 400 is mounted on the positive terminal 200.

The positive electrode terminal 200 includes: a mounting portion 210, a terminal pin 220, and a contact 230, the contact 230 being disposed on a surface of the mounting portion 210; the anti-reverse installation plate 400 is arranged on the surface of the positive terminal 200 and is arranged around the contact 230; the anti-reverse board 400 does not cover the contacts 230.

The positive pole of the dry battery is provided with a copper cap which is protruded from the positive pole end of the battery, when the dry battery is correctly installed, the positive pole end of the dry battery is supported on the anti-reverse installation plate 400, and the copper cap is just protruded to be contacted with the contact 230; however, if the dry cell is reversely mounted, the negative end of the dry cell cannot be electrically connected with the positive terminal 200, the estimated end of the dry cell is supported on the reverse mounting preventing plate 400, and the negative end is generally in a planar structure, does not have a copper cap or a protruding structure the same as the copper cap, and cannot be contacted with the contact 230, so that the conduction cannot be completed, and a user can intuitively find that the dry cell cannot be contacted with the positive terminal 200, thereby effectively reminding the reverse mounting.

Specifically, the positive terminal 200 is inserted and mounted on the bottom plate 110 of the mounting housing 100 through the terminal pin 220, and the terminal pin 220 facilitates subsequent electrical connection with the circuit board.

The anti-reverse installation plate 300 is arranged in a concave shape, and the middle hollow part is used for exposing the contact 230; the anti-reverse mounting plate 300 is provided with pins 310, and is inserted and mounted on the mounting portion 210 through the pins 310.

The upper end of the anti-reverse installation plate 300 is bent to form a bent plate 320, and the bent plate 320 is hung on the positive terminal 200 to complete more stable connection.

In other embodiments, the anti-reverse mount plate 300 may be other shapes.

The negative terminal 300 is provided with a contact piece 310, one end of the contact piece 310 is connected with the negative terminal 300, the other end is a free end, and the negative electrode of the dry battery is connected with the free end of the contact piece 310.

The reverse installation of the dry battery can be effectively prevented by the arrangement of the reverse installation preventing plate 400.

The battery assembly structure can be applied to a smoke detector which is used for detecting smoke and preventing fire, the smoke detector is provided with a shell and a circuit assembly arranged in the shell, and the battery assembly structure is applied to the smoke detector and can effectively prevent a dry battery from being reversely arranged.
