How Do I Choose The Right Rectangular Connector?

Connector Insert is usually composed of a plug and a socket, where the plug is also called a free-end connector and the socket is also called a fixed connector. Electrical connection and disconnection are completed by plugs, sockets, insertion and disconnection, and various plug and socket connections are being made. For circular connectors, there are mainly three ways: threaded connection, bayonet connection and marble connection. Among them, threaded connection is more common, with the advantages of simple processing technology, low manufacturing cost, and wide application range, but the connection speed is slow and it is not suitable for occasions that require frequent plugging and unplugging and quick connection. Because the leads of the three bayonet slots are long, the bayonet connection has a relatively high connection speed, but it is more complicated to manufacture and more expensive. The marble connection method is the fastest of the three connection methods, and the connection, disconnection and locking functions can be obtained by moving on a straight line without rotation. Because it is a direct push-pull connection, it is only suitable for connectors with a smaller overall breaking force. It is usually more common in smaller connectors. The installation and installation methods of special-shaped connectors are front-loading and rear-loading, and the installation and fastening methods include rivets, screws, clamps or quick locking of the connector itself. There are also plugs and sockets, which are endless connectors called relay connectors. The shape of connectors is constantly changing, and users mainly choose from the aspects of straight type, curved type, outer diameter of wire or cable, fastening requirements for the shell, volume, weight, whether it is metal contact. Connectors such as hoses used in panels should also be selected from the aspects of aesthetics, shape, color, etc.
According to the cross-section of the wire, the correct bobbin must be correctly selected. The crimp connection is a permanent connection and can only be used once. Winding is to wrap the wire directly around the angular contact winding post. When winding, the wire is wound with controlled tension and pressed against the edge of the contact winding post to form a sealed contact. There are several requirements for winding: the nominal value of the wire diameter must be within the range of 0.25mm1.0mm, and the elongation of the conductor material must be at least 15% when the wire diameter is not greater than 0.5mm. When the wire diameter is greater than 0.5mm, the elongation of the conductor material is greater than 20%. Winding tools include winding guns and fixed winding machines.
