In the manufacturing process of electronic components such as mobile phones and computers, especially multi-layer circuit boards, there is generally a fixed connection between the multilayer circuit boards or other components, and the aluminum alloy blind pop rivets play a vital role here. It overcomes the shortcomings of the traditional connection method, not only can realize self-riveting, the installation is simple and fast, the rupture caused by the impact and other undesirable phenomena do not occur, and it is not easy to fall off, and the quality and service life of the product are improved.
The aluminum alloy blind pop rivets comprises a cap head and a hole column, the cap head is fixed on one end surface of the hole column, and a tip portion is formed on the other end surface of the hole column, and the end of the hole column near the cap head is along the side of the side of the cap An annular groove is formed inwardly concave. After the hole of the aluminum alloy blind pop rivets is placed into the blind hole of the metal piece, the tip of the end face of the hole column is squeezed into the metal material under the end face of the hole column by an external force.
At the same time, the metal material on the side of the hole column is also pressed by the side of the hole column, so that part of the metal material is completely squeezed into the annular groove, so that the annular groove is filled more well, and the tip is pushed into the metal. In the material, the aluminum alloy blind pop rivets can be double-positioned, thereby realizing the self-riveting of the rivet.www.yukerivet.com
