Description

electrical connector

【Technical field】

The invention relates to an electrical connector, in particular to an electrical connector with an electronic protection element inside.

【Background technique】

The electrical connector is welded on the circuit board to connect with the mating plug, thereby establishing signal transmission between the external electronic device and the circuit board. Now, when various electrical connectors are mated with mated plugs, their input/output ports may become the entry point of ESD (ElectroStatic Discharge), thereby providing a path for the entry of ESD. In fact, ESD can be generated when a person comes into contact with an electrical connector or conductive terminal. Moreover, when the humidity of the surrounding environment is reduced by 50% or below, the instantaneous voltage generated by the static charge accumulated by the human body can exceed 20,000 volts. Usually, ESD produces very little current, but the high voltage is enough to destroy some electronic devices, such as semiconductor components. Therefore, when the electrical connector is installed on the circuit board, if an ESD phenomenon occurs, it is easy to damage the electronic components on the circuit board.

In order to prevent ESD, some components are generally provided on the electrical connector to provide ESD protection. For example, some connectors are provided with shielding sheets at the ports for grounding. At the same time, the circuit board on which the electrical connector is mounted will also be provided with ESD protection components. Nowadays, various devices such as digital cameras, mobile phones, MP3 and PDA have more and more functions, and the input/output connectors in these devices also increase accordingly. ESD is also more likely to enter these devices and damage the electronic devices on the circuit board. Therefore, the IC design of the circuit board is more sensitive to ESD, and ESD becomes a challenge for the design. The IC designer of the circuit board must make the IC provide the most effective ESD protection possible, but this also provides circuit board space for additional protection components, which is contrary to the development trend of miniaturization of various devices today.
