[0002] The button battery holder is a button battery connector, which is used to load button batteries. It is generally welded on the PCB board and used to power the module clock. Button batteries are widely used in electronic products such as cameras, mobile phones, computers and mobile power modules.

[0003] According to the existing Chinese utility model patent with the announcement number CN208538961U, a button battery holder for preventing the deformation of the negative contact piece is recorded, which includes a battery base and a metal contact piece, and the metal contact piece includes a negative contact piece and a positive contact piece, and the negative contact piece and the positive contact piece are fixed on the battery base. The battery button holder on the market generally adopts a pin-shaped tail negative spring piece to be inserted and welded with an external PCB board. The pin-shaped welding structure, on the one hand, is easy to fall off before the button battery holder is assembled to the external PCB board. On the other hand, when the button battery holder is welded to the inside of the PCB board, the cross-sectional area of ​​the pin-shaped tail negative spring piece is small, resulting in low welding stability and strength, which makes it easy for the button battery holder to fall off from the PCB board. Therefore, in view of these current situations, it is urgent to develop a patch-type button battery button holder to meet the needs of actual use. Utility Model Content

[0004] The utility model aims to provide a patch type button battery holder, which is used to solve the defects that the metal contact sheet is easy to fall off before the button battery holder is assembled to the external PCB board, and the button battery holder and the PCB board are easy to fall off.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A patch-type button battery socket includes a base, a first conductive spring and a second conductive spring. The center of the base is a receiving cavity opening upward, and the two sides of the base are mounting portions for arranging the first conductive spring and the second conductive spring. One end of the first conductive spring is a first welding portion, and one end of the second conductive spring is a second welding portion.

Horizontally extending welding plates are provided on both sides of the base, and the middle part of the welding plate is provided with a plug-in hole matching the plug-in sleeve structure. The first welding portion and the second welding portion are both plugged and fixed through the plug-in sleeves and the plug-in holes of the welding plate.

[0008] In the above description, as a further solution, the end of the first conductive spring away from the first welding portion is a first contact portion, which is used to electrically connect to the battery. The first contact portion is bent and extended toward the bottom end surface of the accommodating cavity, and the end of the first contact portion is inclined upward.

[0009] In the above description, as a further solution, one end of the second conductive spring away from the second welding portion is a second contact portion, which is used to electrically connect to the battery. The second contact portion is bent and extended toward the opening of the accommodating cavity, and the end of the second contact portion is arranged above the accommodating cavity along the horizontal structure.

After the solder melts, it can flow to the inner wall of the plug-in sleeve. When the solder and the plug-in sleeve are fused and fixed, the solder can be located in the inner part of the plug-in sleeve in an inverted truncated cone shape, so that the patch-type button battery socket and the external PCB circuit board form an upper and lower limit structure through the solder, which increases the structural stability between the patch-type button battery socket and the external PCB circuit board. At the same time, the cross-sectional width of the solder in the inverted truncated cone structure is greater than that of the existing pin-shaped structure, thereby enhancing its own rigidity.

After the solder 4 melts, it can flow to the inner wall of the plug-in sleeve 25. When the solder 4 and the plug-in sleeve 25 are fused and fixed, the solder 4 can be located inside the plug-in sleeve 25 in an inverted truncated cone-shaped structure, as shown in FIG. Figure 5As shown, the upper and lower limit structures are formed between the SMD button battery holder and the external PCB circuit board through the solder 4, which increases the structural stability between the SMD button battery holder and the external PCB circuit board. At the same time, the cross-sectional width of the solder 4 in the inverted truncated cone structure is greater than that of the existing pin-shaped structure, thereby enhancing its own rigidity.

[0024] Specific as Figure 2 As shown, the middle parts of the first conductive spring sheet 2 and the second conductive spring sheet 3 are respectively the first bending portion 22 and the second bending portion bent upward, and the first conductive spring sheet 2 and the second conductive spring sheet 3 are respectively buckled and fixed to the mounting portion 12 through the first bending portion 22 and the second bending portion.
