TXGA -- vh3.96 connector specification: VH is generally 3.96mm wire to board connector, TXGA model is FWF39601, wire to board connector structure is very simple: the electrode (contact) placed in the shell (shell).
There are two types of contacts: a "plug" and a "socket" in the shape of a stick or piece. Squeeze the plug completely into the socket and cover it to achieve "pairing". In general, the socket is connected to the wire and the plug to the substrate, but this can be switched depending on usage. Connections between wires and contacts are generally made using "pressure bonding" techniques, such as compression terminals.
"Pressure welding" can also be used to connect wires and contacts. Pressure welding technology is used for low-current connections, allowing for full connections by simply connecting insulated wires to contacts. This approach, while convenient, may reduce durability. The above two technologies can avoid overheating caused by soldering technology and protect the connection from damage. In addition, the airtight connection area can be maintained stable because it is not exposed to air.
