Problems solved by technology

[0003] Small-pitch miniaturized rectangular electrical connectors have short service life, poor high-temperature resistance, and poor corrosion resistance when used in harsh environments, which increases the cost of use. At the same time, small-pitch miniaturized rectangular electrical connectors need to be installed through installation Tools are used for installation, which is not conducive to actual installation. In addition, it is easy to fail to insert accurately during installation, and it is easy to damage the contact pins.
