[0005] Furthermore, the elastic hook is a Z-shaped metal spring, and the bend at the top of the elastic hook has a smooth transition structure.

[0006] Furthermore, the base edge is provided with a support member integrally formed with the base, and the top and bottom of the support member are fixedly connected to the PCB board and the base.

[0007] Furthermore, the top of the support member is bent at a 90-degree angle, and the bent part is attached to the PCB board.

[0008] Furthermore, the conductive spring is curved upwards in an arc shape.

[0009] Furthermore, the length of the 90-degree bend at the top of the support member is 1-3 millimeters.

[0013] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0014] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0015] like Figure 1-4 As shown, this utility model provides a combined button battery holder, including a PCB board 1 and a base 4 for placing the button battery 2. The PCB board 1 is provided with a round hole 11 for accommodating the button battery 2. The base 4 is located below the round hole 11 with its opening facing upward and is fixedly connected to the lower surface of the PCB board 1. The edge of the round hole 11 is provided with circumferentially distributed elastic hooks 3, which are fixedly connected to the upper surface of the PCB board 1. A through hole 43 is provided in the middle of the base 4, and a conductive spring piece 42 that is integral with the base 4 and slightly upturned extends from the edge of the through hole 43.

[0016] PCB board 1 serves as the circuit foundation for the entire battery holder, providing a platform for the electrical connection between button battery 2 and other electronic components, enabling the battery to provide stable power to the circuit system and ensuring the normal operation of electronic devices.

[0017] The round hole 11 is used to accommodate the button battery 2, providing an accurate installation position for the button battery 2, ensuring that the battery is placed stably in the battery holder, and facilitating the installation and removal of the battery.

[0018] The base 4, with its opening facing upward, is located below the round hole 11 and is fixedly connected to the lower surface of the PCB board 1. It serves to support the button battery 2 and, together with the PCB board 1, fixes the button battery 2 in a specific space, preventing the battery from shaking or shifting during use and ensuring the reliability of the connection between the battery and the circuit.

[0019] The circumferentially distributed hooks are located above the edge of the circular hole 11 and are fixedly connected to the upper surface of the PCB board 1. When the button battery 2 is inserted into the circular hole 11, the elastic hooks 3 can use their elasticity to hold the battery in place, further fixing the position of the battery and preventing the battery from coming out from above, thus enhancing the stability of the battery installation.

[0020] The through hole 43 provides space for the conductive spring 42, and may also facilitate heat dissipation of the battery holder to a certain extent, avoiding the accumulation of heat generated during battery operation, which would affect battery performance and lifespan.

[0021] The conductive spring 42 is an integral part of the base 4 and is slightly upturned, giving it good elasticity and conductivity. When the button battery 2 is installed, the conductive spring 42 can make close contact with the battery's electrodes, achieving a reliable electrical connection and transferring the battery's electrical energy into the circuit.

[0022] See Figure 2 , Figure 3 and Figure 4 The elastic hook 3 is a Z-shaped metal spring. The upper part of the elastic hook 3 has a smooth transition structure. When the button battery 2 is inserted, the end of the elastic hook 3 abuts against the top surface of the button battery 2 to restrict the movement of the button battery 2.

[0023] See Figure 3 and Figure 4 The base 4 has a support member 41 integrally formed with the base 4 at its edge. The top and bottom of the support member 41 are fixedly connected to the PCB board 1 and the base 4.

[0024] The support member 41 provides additional support between the PCB board and the base 4, dispersing these external forces and preventing the PCB board from deforming, bending, or breaking due to uneven stress, thus ensuring the stability and integrity of the overall battery holder structure. The support member 41 is integrally formed with the base 4, with its top fixedly connected to the PCB board and its bottom fixedly connected to the base 4, increasing the number of connection points and the connection strength between the PCB board and the base 4.

[0025] See Figure 3 and Figure 4The top of the support member 41 is bent at 90 degrees, and the bent part is in contact with the PCB board 1, which increases the contact area between the support member 41 and the PCB board 1 and increases the connection strength.

[0026] The conductive spring 42 is curved upwards, and the free end of the conductive spring 42 has a certain elastic pressure when it contacts the bottom of the button battery 2, ensuring that the conductive spring 42 and the bottom of the button battery 2 maintain a good electrical connection.

[0027] The length of the 90-degree bend at the top of the support member 41 is 1-3 mm. This length ensures sufficient contact area to enhance connection strength without affecting the overall structural layout due to excessive length.
