Application environment of different shapes of hardware battery shrapnel

The production of metal battery shrapnel is a special process in which materials (metal or non-metal) are processed into parts (or semi-finished products) through cold stamping of stamping dies. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. 1. The current size of round round hardware battery shrapnel is concentrated on the smaller end, like 2.5mm-5mm, which are the advantages of this series of shrapnel. The round series can also be up to 16mm or greater, and the strength is generally From 100gf to 600gf. At the same time, sometimes it is possible to customize shrapnel of various specifications and sizes according to customer requirements to meet the different needs of customers. The round metal shrapnel has dots and no dots, with dots and dots. It is divided into one point and multiple points (3-5). The existence of pits reduces the occurrence of poor conduction to a certain extent and increases the conduction performance of the product. In addition, the design is convenient, considering the membrane switch manufacturer For the special requirements, we will add medium rice and three side rice to a certain size of the circle to achieve the effect of increasing height and feel. From the shape of the product, it is a relatively regular shape, so in the conventional In the specifications, the life of the round is often longer than that of other specifications of metal shrapnel. 2. The advantage of the triangular metal battery shrapnel is that it can have the greatest strength under the same diameter. For example, those larger than 600gf and above are the advantages of this series of shrapnel. It is used in special occasions, such as the need to press hard to avoid Manual misoperation, etc. The conventional size of this triangular shrapnel is from 5-12mm, and the strength is generally between 150gf and 6,000gf. In addition, unlike other models, this shrapnel product can be made with two legs. Angles. The width is generally 0.8mm, and there are also specifications such as 0.7~1.0mm; the foot length is divided into three types: short feet, 0.8mm long; middle feet: 1.5mm long and long feet: 3.0mm long or longer. Rely on two The corners can be conveniently positioned on the PCB board, eliminating the need for soldering or surface filming. 3. Cross-shaped cross-shaped series hardware battery shrapnel refers to four-leg shrapnel, also called four-corner shrapnel. It is mainly used for single and double panels, soft boards and membrane switches. There are two types of cross-shaped shrapnel: no meter position ( Also called'point'), with a medium meter. From its structure, the height of the cross-shaped shrapnel is often higher than other specifications, so the hand feel is better than other specifications. Therefore, when there is more space on the PCB, This series of shrapnel can be used. Like commonly used membrane switches, most of them use cross-shaped shrapnel. The maximum cross-shaped series can be 20mm or more, and the strength is generally between 120 grams force and 600 grams force. .　　4. Other specifications 　　 include rectangular shape, irregular shape, etc.
