Problems solved by technology

[0003] At present, there are mainly two types of battery shrapnel. One is to use wire spring battery shrapnel. This method is relatively stable in power supply, but its elasticity is small, the dimensional accuracy is low, and the conductive area is small, the conductive distance is long, and the impedance is large. The other is Leaf spring battery shrapnel, this type of battery shrapnel mainly has two materials: stainless steel and phosphor bronze. The impedance of stainless steel shrapnel is relatively large, and the material of phosphor bronze shrapnel is relatively soft. Easily deformed, resulting in power failure

Embodiment 1

[0035] refer to Figure 1-Figure 3 , which is Embodiment 1 of the battery elastic sheet structure of the present invention, the battery elastic sheet structure includes an elastic sheet and an elastic support member. The elastic sheet includes a base plate 110 and an elastic arm 120 bent along one end of the base plate 110 . The elastic arm 120 includes a bent portion 121 and an abutting portion 122 , the substrate 110 is connected to the abutting portion 122 through the bent portion 121 , and the abutting portion 122 is used to abut against a polar contact of the battery to form electrical conduction. The elastic supporting member is supported and fixed between the base plate 110 and the abutting portion 122 . Wherein, the shrapnel is made of phosphor bronze, and the elastic supporting member is a spring 300 .

[0036] In the battery shrapnel structure above, the shrapnel is made of phosphor bronze with good electrical conductivity. After the battery is installed, the elast...

Embodiment 2

[0042] Such as Figure 4 Shown is the second embodiment of the battery shrapnel structure of the present invention. In this embodiment, the elastic supporting member is a buffer pad 400, and one side of the buffer pad 400 is in contact with the substrate 110, and the other side is in contact with the inner surface of the contact portion 122'. The buffer pad can adopt soft materials such as foamed plastics and foam cotton. Compared with the elastic arm 120 in the first embodiment, the elastic arm 120' in this embodiment does not require a large installation space for spring installation, so the bending portion 121' can be designed as a small arc segment.

[0043] In order to fix the buffer pad, the end of the contact portion 122' is bent toward the side close to the substrate to form a supporting portion 123', and the bottom of the buffer pad 400 is supported on the supporting portion. In another embodiment, the buffer pad 400 may also be fixed between the base plate 110 and ...

Abstract

The invention discloses a battery elastic sheet structure and an electronic product, the battery elastic sheet structure comprises an elastic sheet and an elastic support member, the elastic sheet ismade of phosphor bronze, the elastic sheet comprises a substrate and an elastic arm bent along one end of the substrate, the elastic arm comprises a bending portion and an abutting portion, the substrate is connected with the abutting portion through the bending portion, and the abutting portion is used for abutting against a battery; and the elastic support member is arranged between the substrate and the abutting portion in a supporting mode. According to the battery elastic sheet structure, the elastic sheet is phosphor bronze with good conductivity, after the battery is installed, the elastic support member provides a certain supporting force for the elastic arm, the elastic sheet structure design solves the problem that the phosphor bronze elastic sheet is easy to deform in the sheetproduction and use process, simultaneously ensures that the impedance value is lower, and reduces the impedance value of the whole elastic sheet and prolongs the service life of the product battery due to the fact that the battery elastic sheet structure adopts the design that the elastic sheet and the elastic support member are connected in parallel.

Description

technical field [0001] The invention relates to a battery shrapnel, in particular to a battery shrapnel structure and an electronic product. Background technique [0002] Nowadays, the types of electronic products are becoming more and more extensive, and they are deeply loved by consumers, and the power supply performance of electronic products is an important indicator to measure the reliability of electronic products, so the selection of battery shrapnel is very important. [0003] At present, there are mainly two types of battery shrapnel. One is to use wire spring battery shrapnel. This method is relatively stable in power supply, but its elasticity is small, the dimensional accuracy is low, and the conductive area is small, the conductive distance is long, and the impedance is large. The other is Leaf spring battery shrapnel, this type of battery shrapnel mainly has two materials: stainless steel and phosphor bronze. The impedance of stainless steel shrapnel is relativ...
