When the pin of the conductor in the pin enters the socket, the socket will expand excessively, the shape variable will exceed its elastic deformation range, resulting in plastic deformation, which will cause the conductor in the socket to be damaged; on the contrary, if the pin diameter is too small, when the pin and socket cooperate, the gap between the pin and the socket wall is too large, the two inner conductors cannot be contacted closely, the contact resistance becomes larger, and the electrical property of the connector is large The energy index will be very poor. Then, the music connector is compiled to explain how the pin socket of the power down connector is composed:
The components of rectangular electrical connection include: insulator, contact part and shell
The components of circular electrical connector include: shell, insulation mounting plate and contact.
The connector is composed of socket, plug and accessory. The socket and plug are used to fix the contact parts and connect them after being plugged in. Accessories are used to fix wires, protect welding (pressing) points from force, and accessories are connected to plugs or plugs by thread or screw.
The plug and socket of circular connector are threaded, three curved groove bayonet, push-pull connection, three-end threaded connection, half circle ring fastening, etc.; the plug of rectangular connector of pin socket and socket are directly inserted and connected with screw connection and compression device.
USB extension pin, front panel extension pin, headphone interface extension pin These pins we often use, for friends who often install computers, how to connect these pins can be said to be light and familiar. But there are also places we don't know about the pins that we have become accustomed to.
When we mention the word "needle", everyone's reaction is slender, conical, and it will be quite painful to be tied. But the "Jack" on the motherboard is not really round. If you look carefully, you will find that the cross-section of the pin on the motherboard is square, and the whole pin is in the form of a cube.
