Example 1

The utility model provides a battery holder, please refer to fig. 1-3, battery holder 1 includes:

the upper cover plate 11 is used for being connected with the button battery and fixing the button battery on the circuit board;

at least one extension part 12 formed by extending downward the edge of the upper cover plate, the upper cover plate and the extension part forming a battery accommodating space 15;

and the constraint part 16 is connected to the upper cover plate and limits the button cell in the cell accommodating space 15, and an included angle smaller than 90 degrees is formed between the constraint part and the upper cover plate.

Wherein, the said restraint part forms an included angle less than 90 degrees with the upper cover plate, which can be specifically understood as follows: the constraint part and the upper cover plate are inclined at a certain angle and face the battery accommodating space.

In some embodiments, the restraining portion is an elastic member. The elastic component is arranged at the position of the battery plug inlet 18, the button battery is plugged into the battery accommodating cavity from the battery plug inlet, the constraint part 16 bends and deforms upwards under the action of thrust applied by the button battery, and the button battery can be normally plugged into the battery accommodating cavity. After the button battery is completely plugged into the battery accommodating cavity, the constraint part 16 rebounds to abut against the button battery, so that the button battery is ensured not to slip off in subsequent use.

In some embodiments, the elastic member may be a plate-shaped member or an arc-shaped member, which deforms when subjected to a force, and generates a rebound force to the object to which the force is applied, and returns to an original state after the external force is removed. The restraining portion used in fig. 3 is a straight plate-like member, but it is needless to say that the form shown in fig. 4 may be used, and the state shown in fig. 4 may be used as it is at the time of assembly. The elastic component comprises a first elastic part 161 and a second elastic part 162 formed by bending the front end of the first elastic part and then facing the battery accommodating space, and when the button battery is in the battery accommodating space, the front end of the second elastic part is lower than the top surface of the button battery.

As shown in fig. 3, H2 is the height of the top surface of the assembled battery from the surface of the PCB, and H1 is the height of the restraint from the surface of the circuit board after springback, requiring H2-H1>0.3 mm.

In the above embodiment, the case that the front end of the elastic component is lower than the top surface of the button cell after the cell is plugged into the cell accommodating space is described. When the design is shown in fig. 5, the elastic component can also be directly propped against the top surface of the button cell at the front end part of the elastic component after the battery is plugged into the battery accommodating space, so that the battery is stressed by downward force and can be more reliably pressed on the circuit board. After the battery is plugged into the battery accommodating space, the battery can generate upward pressure on the elastic part, the elastic part deforms, downward rebound force can be generated, and the battery is pressed on the circuit board. The elastic member in fig. 5 is a straight plate-like member, and may be in the form shown in fig. 6, which is directly in the state shown in fig. 6 at the time of assembly.

In some embodiments, two elastic members may be provided, one of which is configured such that when the button cell is in the cell accommodating space, the front end of the elastic member is lower than the top surface of the button cell, and the other of which is configured such that when the button cell is in the cell accommodating space, the front end of the elastic member directly abuts against the top surface of the button cell.

In some embodiments, the number of the extension portions is 2, and the two symmetrically arranged extension portions include a first extension portion 121 formed by extending the edge of the upper cover plate downward and a second extension portion 122 formed by extending the first extension portion in a direction away from the battery accommodating space, and the first extension portion and the second extension portion form an included angle equal to 90 °.

It can be understood that the first extending section is vertically downward, and the second extending section horizontally outwards deviates from the battery accommodating space. When the extension part is attached to the button cell, the extension part extends to the bottom surface along the top surface of the button cell to form a first extension section, and the first extension section horizontally extends outwards for a certain length to form a second extension section.

In some embodiments, the battery holder is fixed by soldering, and particularly, reflow soldering may be used. Welding holes are arranged on the second extension sections of the two symmetrically arranged extension parts. The shape of the welding hole is not limited to the circular shape in the drawing, and includes a triangular shape, a rhombic shape, a rectangular shape, an oblong shape, and the like. The form of the hole also includes incomplete hole breaking designs.

In some embodiments, the number of extensions may be 3, two of which are symmetrically disposed and have a structure identical to the structure of the previously described extension, and the other of which differs from the symmetrically disposed two extensions in that there is no horizontal extension. The button cell positioning device has the function of positioning the button cell when the button cell is plugged into the cell accommodating space.

The utility model discloses a battery holder configuration optimization increases spacing fixed-about portion promptly, avoids the risk that the roll-off drops after the battery equipment.

the solder columns are formed in the solder holes on the soldering part in the reflow soldering process, and comprise solder layers 32 formed between the soldering part and the circuit board and solder layers 31 formed in the solder holes, as shown in fig. 8, the solder columns are embedded into the pin holes in an ⊥ shape to form the positioning column effect, so that the horizontal thrust F resistance of the battery holder can be effectively improved.

In one embodiment, the solder post further includes a solder layer 33 formed on the upper surface of the solder portion. As shown in fig. 9, the solder columns are "i" shaped and embedded into the pin holes to form the positioning columns, which not only can effectively improve the horizontal thrust F resistance of the battery holder, but also can increase the welding strength in the direction perpendicular to the surface of the PCB.
