Background technique

Electronic connectors are special devices used to supplement power or transmit data for mobile communication devices or microcomputers or automated instruments. The existing electronic connectors have the following defects:

Take the mobile phone magnetic charging cable as an example, please refer to Figure 1, the contact surface between the two magnetic heads I and II Ⅲ is perpendicular to the plane where the mobile phone screen is located, and is also perpendicular to the plane IV where the circuit board of the magnetic head itself is located. When the movable terminal is pulled or pulled, the direction V of the pulling force is parallel to the direction VI of the connecting force (magnetic attraction force or clamping force, etc.) between the two connectors, that is, parallel to the release of the two connectors In this way, even if the connector is slightly pulled or disturbed, the stability of the connection will be affected, and there are problems such as unstable electrical connection, high impedance, and insufficient bearing capacity, especially when the rotation between the two magnetic heads occurs. These problems are particularly serious.
