What is a patch connector?
There are many types of connectors, which can be divided into circular connectors, rectangular connectors, square connectors, and custom connectors. According to the contact body termination form: crimping, welding, winding; screw (cap) fixed; according to the connection method can be divided into: board to board connector (B to B), wire to board connector (W to B), Wire-to-wire connector (W to W). Let's talk about the patch connector in the wire-to-board connector today.
Surface solder mounting technology has been used by some manufacturers since the 1950s. However, the use of patch connectors has only recently begun, and has gradually been valued by manufacturers. This situation is due to the technical difficulties faced by the SMT connector and the failure to perceive the patch panel to save the board area. As the patch process can be found to improve the production efficiency and reduce the cost of the manufacturer, the board area can be reduced, and the design flexibility can be improved, so that the patch connector can be widely used.
Patch connectors are divided into: horizontal connector (SMT) and vertical connector (DIP). SMT is generally mounted with leadless or short lead surface mount components. It is necessary to print solder paste on the board first, then mount it on the mounter, and then fix the device by reflow soldering. DIP solders are devices that are packaged in a straight-in form and are fixed by wave soldering or manual soldering.
The patch connector is over 260° above 3-5 s. The composition of the patch connector: plastic parts and pin needles, the plastic parts are generally PA6T and PA9T, are high temperature resistant materials. Patch connectors are generally used in highway cameras, stereo DC fans, smart electronics, air conditioners, HD LCD TVs, notebook computers and other fields. Among them, the material of Pin is generally brass, bronze, phosphor bronze, and the like. The plating is generally gold plated (half gold) or tin plated. The coating effect of the pin needle is anti-oxidation, improve the conductivity and increase the transmission speed of the signal.
