Description
Technical Field
[0001] The utility model relates to the technical field of connecting accessory equipment, in particular to a safety connector. Background Art
[0002] Connectors, also known as connectors, are components used in electronic engineering technology to achieve detachable connections between circuits. Their main function is to build bridges where circuits are blocked or isolated, allowing current to flow, thereby achieving the intended function of the circuit. Connectors usually consist of two parts, a plug and a socket. These two parts can be completely separated when not connected. Connectors can be classified in many ways according to different standards, including classification by shape (such as round, rectangular), classification by frequency (such as high frequency, low frequency), classification by purpose (such as power connectors, signal connectors, coaxial connectors, etc.) and classification by PCB welding method (such as through-hole welding connectors, surface mount connectors, etc.). Connectors are widely used in various electronic devices and systems, including consumer electronics (such as mobile phones, computers, TVs, etc.), industrial control, automotive electronics, medical equipment, communication equipment, and aerospace.
[0003] At present, the positive connector and the negative connector of the plug-in component may become loose and unstable when connected, which not only affects the normal operation of the equipment but also may bring safety hazards. Unstable connection will lead to a decrease in contact area and an increase in contact resistance, thereby causing signal attenuation and affecting the transmission quality of data or audio and video signals. Poor contact may cause the equipment to have power at times and no power at times, affecting the continuity and reliability of the equipment, and even causing the equipment to fail to start or operate normally. In order to solve this technical problem, the utility model proposes a safety connector. Utility Model Content
