[0035] [According to Rule 26 Correction 11.07.2024] The terms used in the embodiment part of the present application are only used for explaining the specific embodiments of the present application, and are not intended to limit the present application, and the embodiment of the present application will be described in detail below in conjunction with the drawings.

[0036] [According to Rule 26 Corrected 11.07.2024] As shown in FIGS. 1-4, the embodiment of the present application provides a button cell A seat with an anti -fall cover, comprising a base 1, an upper cover 2, a positive contact piece 3 and a negative contact piece 4; the base 1 is provided with a battery accommodating groove 11, the battery accommodating groove 11 is used for installing the button cell, one side of the base 1 is provided with a first avoiding groove 12, the two sides of the first avoiding groove 12 respectively extend outward to form a first buckle part 13, the first buckle part 13 is symmetrically provided with two, the opposite sides of the first buckle part 13 are respectively provided with a first buckle groove 14; the inner wall of the battery accommodating groove 11 is provided with a second buckle groove 15; the positive contact piece 3 is installed on one side of the battery accommodating groove 11 and is electrically connected with the button cell; the negative contact piece 4 is installed at the bottom of the battery accommodating groove 11 and is electrically connected with the button cell upward; the upper cover 2 is symmetrically provided with a second buckle part 21 corresponding to the first buckle part 13, and is provided with a second buckle tongue part 22 corresponding to the second buckle groove 15; the upper cover 2 is inserted into the second buckle groove 15 through the second buckle tongue part 22, and is buckled in the first buckle groove 14 in cooperation with the second buckle part 21, so as to lock the button cell in the battery accommodating groove 11; when the upper cover 2 is unlocked, the second buckle part 21 is elastically deformed under the action of external pressing force, so as to be separated from the first buckle groove 14.

[0037] [According to Rule 26 Corrected 11.07.2024] In the embodiment, the second buckle part 21 comprises an elastic force arm part 211 and a first buckle tongue part 212, the first buckle tongue part 212 extends downward from the bottom of the elastic force arm part 211.

[0038] [According to Rule 26 Corrected 11.07.2024] The existence of the elastic force arm part 211 makes the second buckle part 21 have enough elasticity, which can be deformed when subjected to external pressure, facilitating cooperation and separation with the first buckle groove 14. At the same time, after the pressure disappears, the elastic force arm part 211 can quickly restore to the original state, ensuring the stability and durability of the button cell seat.

[0039] [According to Rule 26 Corrected 11.07.2024] As shown in FIG. 5, in the embodiment, a pressing part 23 extends outward from the outer side of the elastic force arm part 211. The existence of the pressing part 23 provides a clear operation point for the user. The user can easily find and apply pressure to the pressing part 23 without excessive exploration or trial. This enables the user to quickly and accurately perform the operation when the upper cover 2 needs to be opened to replace or remove the button cell.

[0040] [According to Rule 26 Corrected 11.07.2024] As shown in FIG. 5, in the embodiment, the two second buckle parts 21 have a spacing H, and when the two second buckle parts 21 are pressed relative to each other, they can approach each other within the spacing.

[0041] [According to Rule 26, correct on 11.07.2024] As shown in Figure 4, in this embodiment, the bottom of the base 1 is provided with support feet 5. By providing three support feet 5, the contact pressure between the base 1 and the PCB can be dispersed. Even if the product deforms slightly in some cases, due to the height of the glue column, the contact area can still be maintained on these three support feet 5, thereby limiting the range and impact of deformation. This helps to maintain the stability and accuracy of the entire structure.

[0042] [According to Rule 26, correct on 11.07.2024] As shown in Figure 2, in this embodiment, the side edges of the base 1 are symmetrically provided with third clearance grooves 16. The presence of the third clearance grooves 16 allows the user to more easily pinch the button cell with their fingers from the side when replacing the battery. Due to the sufficient space provided by the third clearance grooves 16, the fingers can easily enter and pinch the battery, avoiding the difficulty of grasping due to insufficient space.

[0043] [According to Rule 26, correct on 11.07.2024] As shown in Figure 6, in this embodiment, the positive contact sheet 3 is made of metal material, its side is U-shaped, and the positive contact sheet 3 includes a positive elastic contact part 31 and a positive fixed part 32. The positive elastic contact part 31 can be moved close to the positive fixed part 32, the positive elastic contact part 31 is provided with a movable hook 33 on the side close to the button cell, and the side of the battery accommodating groove 11 is provided with a fixed hook 34, the movable hook 33 and the fixed hook 34 are pressed on the surface of the button cell.

[0044] [According to Rule 26, correct on 11.07.2024](1) The positive elastic contact part 31 and the positive fixed part 32 together ensure stable contact with the button cell. This design reduces the gap between the button cell and the contact sheet, reduces resistance, and thus improves the transmission efficiency of the current.

[0045] [According to Rule 26, correct on 11.07.2024](2) By moving the positive elastic contact part 31, the user can easily achieve the separation of the movable hook from the surface of the button cell. This operation makes the battery easy and fast to take out, improving the efficiency of replacing the button cell.

[0046] [Corrected according to Rule 26 11.07.2024] As shown in FIG. 8, in this embodiment, the base 1 is provided with a first mounting portion 17, the first mounting portion 17 is provided with a first mounting slot 171, the positive contact piece 3 is mounted in the first mounting slot 171, a first limiting slot 172 is arranged in the first mounting slot 171, the first limiting slot 172 is used for mounting the positive fixed portion 32, one side of the first mounting portion 17 is provided with a second limiting slot 173, the positive fixed portion 32 is provided with a limiting protrusion 33 corresponding to the second limiting slot 173, and the positive fixed portion 32 is limited from moving upward by the limiting protrusion 33 and the second limiting slot 173.

[0047] [Corrected according to Rule 26 11.07.2024] As shown in FIG. 6, the positive elastic contact portion 31 has a first limiting portion 34 extending on both sides, which can abut against the side of a mounting portion. The first limiting portion 34 limits the deformation of the positive elastic contact portion 31, and indirectly ensures stable contact between it and the battery. Without limiting, the contact portion may deviate from the ideal contact position due to excessive deformation, resulting in poor contact or insufficient contact pressure. With the support of the first limiting portion 34, the contact portion can be kept in a suitable position and angle, ensuring good contact with the battery.

[0048] [Corrected according to Rule 26 11.07.2024] As shown in FIG. 8, in this embodiment, the battery accommodating groove 11 is symmetrically provided with a spring 6 on the bottom surface, and the spring 6 supports the bottom surface of the button cell upward in cooperation with the negative contact piece 4.

[0049] [Corrected according to Rule 26 11.07.2024] (1) This structure makes the button cell stable in the accommodating groove. The spring 6 ensures that the bottom surface of the battery is uniformly stressed, effectively preventing the battery from shaking or tilting in the groove, thereby ensuring stable contact between the battery and the negative contact piece 4. This stable contact is crucial to ensure the normal operation of the circuit and can effectively avoid problems caused by poor contact.

[0050] [Corrected according to Rule 26 11.07.2024] (2) The symmetrical spring 6 not only enhances the stability of the support, but also makes it more convenient to take out the battery. Since the spring 6 has a certain elasticity, when the user takes out the battery, the spring 6 will help the battery to pop out of the groove, reducing the difficulty of manual operation. This design is particularly suitable for scenarios that require frequent battery replacement, improving the user's operation experience.

[0051] [Corrected according to Rule 26 11.07.2024] As shown in Figure 9, in this embodiment, the negative contact tab 4 includes a negative elastic contact part 41 and a negative fixed part 42. The negative elastic contact part 41 extends upwardly from the upper end of the negative fixed part 42, and the bottom surface of the negative elastic contact part 41 extends downwardly to form an elastic support arm.

[0052] [Corrected according to Rule 26 11.07.2024] (1) The negative elastic contact part 41 extends upwardly from the upper end of the negative fixed part 42, which design allows the contact part to fit the negative electrode of the button cell more closely. When the battery is placed into the accommodation groove, the elastic contact part will be slightly deformed under pressure, thereby forming a closer contact with the negative electrode of the battery, ensuring stable transmission of current.

[0053] [Corrected according to Rule 26 11.07.2024] (2) The elastic support arm formed by the downward extension of the bottom surface of the negative elastic contact part 41 not only provides additional support force for the battery, but also can produce certain elastic deformation when the battery is placed in or taken out. This deformation helps to absorb the impact during the battery insertion process, reducing the friction and wear between the battery and the contact tab, thereby prolonging the service life of the battery and the contact tab.

[0054] [Corrected according to Rule 26 11.07.2024] In this embodiment, the bottom surface of the battery accommodation groove 11 corresponds to the negative elastic contact part 41 and is provided with a support protrusion 7. When the negative elastic contact part 41 is pressed down, it deforms around this support protrusion 7.

[0055] [Corrected according to Rule 26 11.07.2024] As shown in Figure 8, the presence of the support protrusion 7 provides a clear deformation center for the negative elastic contact part 41. When the negative elastic contact part 41 is pressed down, it deforms around this support protrusion 7, rather than unevenly deforming across the entire contact part. This directional deformation ensures that the negative elastic contact part 41 can more evenly fit the negative electrode of the button cell, thereby enhancing the stability and reliability of the contact.

[0056] [Corrected according to Rule 26 11.07.2024] As shown in Figure 8, the bottom surface of the battery accommodation groove 11 corresponding to the negative contact tab 4 is also provided with a second avoidance groove 8. Without the second avoidance groove 8, the negative contact tab 4 may be subjected to excessive stress when pressed by the button cell, which may cause the contact tab to be damaged or deformed excessively. The design of the second avoidance groove 8 can disperse these stresses and prevent the contact tab from being damaged excessively, thereby prolonging the service life of the contact tab.

[0057] [According to Rule 26 Corrected on 11.07.2024] In addition, since the second avoiding slot 8 allows the negative contact piece 4 to adaptively deform, it makes the installation and replacement process of the button cell smoother. Users do not need to exert excessive force to put the button cell into the accommodation slot, thereby improving the overall user experience.

[0058] [According to Rule 26 Corrected on 11.07.2024] In this embodiment, the base 1 is made of insulating plastic. The insulating plastic has excellent insulation performance and can effectively isolate the current to prevent electrical faults such as leakage or short circuit. This ensures that the battery holder provides strong protection for the electrical safety of users and devices during use.

[0059] [According to Rule 26 Corrected on 11.07.2024] When taking out the upper cover 2, press the first buckle part 13 inward, let the two second buckle parts 21 approach each other, and the second buckle part 21 leaves the first buckle slot 14 of the first buckle part 13 of the base 1, then lift the upper cover 2 upward, and let the second buckle tongue part 22 on the other side of the upper cover 2 leave the second buckle slot 15; then take out the button cell, first push the positive elastic contact part 31 close to the positive fixed part 32, so that the movable hook is separated from the surface of the button cell, after the side of the button cell lacks buckling pressure, the spring piece 6 cooperates with the negative contact piece 4 to lift the button cell upward, and finally the third avoiding slot 16 clamps the button cell from the side and takes it out.
