Memory alloy wire installation assembly, connection element used by same and connection element fabrication process

Abstract

The invention relates to a memory alloy wire installation assembly, a connection element used by the same and a connection element fabrication process. The technical key lies that the memory alloy wire installation assembly comprises the connection element, a copper sleeve and a welding needle, wherein the connection element is an aluminum-alloy connection element, an insertion hole is formed at the middle part of the connection element, the upper end of the welding needle is inserted into the insertion hole, one end of the connection element is upwards bent and then downwards bent to be inserted into the insertion hole, the copper sleeve sleeves the other end of the connection element, and the aluminum alloy connection element comprises the following constituents: 80% of aluminum, 8% of copper, 7% of magnesium and 5% of zinc. The fabrication process of the connection element comprises the following steps of throwing zinc powder and magnesium powder to a furnace for melting, casting the mixed powder after refining to fabricate a zinc-magnesium alloy block, adding an aluminum block in the furnace, rising a temperature until 830 DEG C to melt, rising the temperature until 880 DEG C, adding copper, refining the zinc-magnesium alloy block after mixing, casting the zinc-magnesium alloy block to an aluminum-alloy thin sheet, making one end of the thin sheet upwards bent and then downwards bent when the temperature is reduced until 220 DGC, cooling the thin sheet to a room temperature, and forming the insertion hole on the thin sheet. By the memory alloy wire installation assembly, a circuit board and the memory alloy wire can be stably connected.

Description

Technical field: [0001] The invention relates to the field of metal materials, in particular to a mounting assembly of a memory alloy wire on a circuit board, an aluminum alloy connector used therein, and a manufacturing process of the aluminum alloy connector. Background technique: [0002] The memory alloy wire used on traditional circuit boards is often very thin, and due to space constraints, it is difficult to find standard terminals for connection. Even if there is no space limit, connecting with a larger terminal will cause buckling Memory alloy wire, weak connection and other problems. And in actual application, many memory alloy wires will adopt special welding methods to realize the connection with the circuit board, but this method will often affect the original characteristics of the memory alloy wire due to technical problems, and the operation is also inconvenient. Invention content: [0003] In order to overcome the deficiencies of the prior art, the presen...
