[0022] Example 1

[0023] like Figures 1 to 3 As shown, a battery compartment in the first aspect of this utility model that can prevent short circuits during button battery installation includes a battery holding compartment 1, a negative electrode conductive sheet 2, and a positive electrode conductive sheet 6. The battery holding compartment 1 is disposed on a circuit board 5, the positive electrode conductive sheet 6 is disposed on the top of the battery holding compartment 1, and the negative electrode conductive sheet 2 is disposed on the bottom of the battery holding compartment 1. Both the negative electrode conductive sheet 2 and the positive electrode conductive sheet 6 are electrically connected to the circuit board 5, and the surface of the circuit board 5 has an insulating layer.

[0024] The negative electrode conductive sheet 2 has a notch 3 on one side of the battery inlet of the battery housing 1. The notch 3 is used to prevent the negative electrode 7 and the positive electrode 8 of the battery from contacting the negative electrode conductive sheet 2 simultaneously when the button battery 4 is inserted into the battery housing 1; specifically, as shown in the figure Figure 1 As shown, during installation, since there is a notch 3 on the negative terminal 7 of the battery, when the button battery 4 is tilted and inserted into the battery compartment 1, the negative terminal 7 of the battery and the positive terminal 8 of the battery simultaneously contact the insulating layer on the surface of the circuit board 5 at the notch, so that a short circuit will not occur. This can effectively prevent the button battery 4 from short-circuiting when inserted into the battery compartment 1.

[0025] In this embodiment, it should be noted that the battery housing 1 is formed by a negative conductive sheet 2 and a positive conductive sheet 6. The positive conductive sheet 6 is a metal spring sheet. The distance between the positive conductive sheet 6 and the negative conductive sheet 2 is slightly less than the thickness of the button cell 4. This ensures that after the button cell 4 is inserted into the battery housing 1, it can be clamped and fixed in the battery housing 1 under the elastic force of the positive conductive sheet 6, thereby ensuring that the button cell 4 can stably output power during use. Both the negative conductive sheet 2 and the positive conductive sheet 6 are circular. The diameter of the negative conductive sheet 2 is smaller than the diameter of the button cell 4, and the diameter of the positive conductive sheet 6 is larger than the diameter of the button cell 4.

[0026] Furthermore, both the negative electrode conductive sheet 2 and the positive electrode conductive sheet 6 are made of stainless steel, which is sturdy and durable, and easy to process and manufacture.

[0027] The technical effect achieved by this embodiment is as follows: the negative electrode conductive sheet 2 is provided with a notch 3 on one side of the battery inlet of the battery compartment 1. When the button battery 4 is installed into the battery compartment 1, the positive and negative electrodes of the button battery 4 will not come into contact with the negative electrode conductive sheet 2 at the same time, so as not to cause a short circuit in the battery and effectively protect the service life of the button battery 4.

[0029] like Figures 1 to 3 As shown, this embodiment provides another battery compartment that can prevent short circuits when installing button batteries. Its structure includes all the contents of Embodiment 1. Only the different parts are described below.

[0030] In this embodiment, notch 3 is an arc-shaped notch.

[0031] In this embodiment, it should be noted that the radius of the notch 3 is larger than the radius of the button cell 4.

[0032] The technical effects achieved in this embodiment are as follows: the notch 3 is an arc-shaped notch, which is convenient for processing and manufacturing, and at the same time, the appearance is more beautiful; the radius of the notch 3 is larger than the radius of the button battery 4, which can effectively prevent the negative electrode 7 and the positive electrode 8 of the button battery 4 from contacting the negative electrode conductive sheet 2 at the same time during installation.

[0033] Example 3

[0034] like Figures 1 to 3 As shown, this embodiment provides another battery compartment that can prevent short circuits when installing button batteries. Its structure includes all the contents of Embodiment 1. Only the different parts are described below.

[0035] In this embodiment, the positive electrode conductive sheet 6 includes a metal conductive sheet and elastic legs. There are multiple elastic legs. The top end of the elastic legs is connected to the metal conductive sheet, and the bottom end of the elastic legs is connected to the circuit board 5. The multiple elastic legs are arranged in a ring along the axis of the metal conductive sheet. The elastic legs are used to clamp the button battery 4 between the negative electrode conductive sheet 2 and the positive electrode conductive sheet 6 after the button battery 4 is inserted into the battery housing 1.

[0036] In this embodiment, it should be noted that the elastic support leg and the metal conductive sheet are an integral structure. The number of elastic support legs is preferably three. Specifically, the elastic support leg includes a first support leg, a second support leg and a third support leg. The first support leg and the second support leg are symmetrically arranged along the axis of the metal conductive sheet, and the third support leg is arranged between the first support leg and the second support leg. The side directly opposite the third support leg is the battery inlet.

[0037] The technical effect achieved by this embodiment is that the positive electrode conductive sheet 6 has a simple structure and is easy to process, manufacture and install.

[0038] Although the utility model has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art.
