Description

technical field [0001] The invention provides a power connector, especially a power connector that can effectively reduce impedance and temperature. Background technique [0002] Press, the design of connectors in electronic circuits usually pays special attention to the two basic signal and power parts, and when designing signal circuits, because the current flowing in signal circuits is usually low, designers usually do not consider the Current changes in electrical properties, but in the signal circuit part due to different transmission changes (such as high-frequency, low-frequency transmission, etc.), signal interference (such as static interference, electromagnetic wave interference, impedance matching, etc.) needs to be considered, but it is The temperature change will not be considered, and the power circuit part is related to the higher current conduction state, so the electrical properties of the power circuit will change the temperature due to the impedance genera...

[0002] Press, the design of connectors in electronic circuits usually pays special attention to the two basic signal and power parts, and when designing signal circuits, because the current flowing in signal circuits is usually low, designers usually do not consider the Current changes in electrical properties, but in the signal circuit part due to different transmission changes (such as high-frequency, low-frequency transmission, etc.), signal interference (such as static interference, electromagnetic wave interference, impedance matching, etc.) needs to be considered, but it is The temperature change will not be considered, and the power circuit part is related to the higher current conduction state, so the electrical properties of the power circuit will change the temperature due to the impedance generated by the high current. Therefore, for the use in the power circuit The power connector designed in must be able to have better heat dissipation characteristics and reduce the impedance generated by the terminals conducting high current, so that the changes in electrical characteristics caused by high current changes can be minimized, and the terminals of the power connector The size of the contact area and the heat dissipation area will affect the quality of power transmission. However, this type of power connector is mostly used on power supplies and server equipment, and is connected to the circuit board. The metal shrapnel that conducts power Due to the impedance generated by the input of high current, it will cause temperature rise, heat generation, etc., which will affect the system performance and safety of the whole machine

[0003] see Figure 8 As shown, it is a three-dimensional appearance view of a known power connector seat body. It can be clearly seen from the figure that one side of the plastic body A has a butt joint A1, and a butt joint A1 is provided on the butt joint A1 for at least one terminal B to pass through. The docking space A10 is set, and the docking part A1 is cut with a plurality of through holes A11 connected to the docking space A10. When the terminal B is transmitting power, the high heat generated by the terminal B can pass through the docking part A1. The plurality of through-holes A11 communicate with the outside to dissipate heat, but since the gap between the docking space A10 of the docking part A1 and the circuit board will become quite narrow after docking, the hot air inside the docking part A1 is difficult to pass through the plurality of through-holes A11 is dissipated to the outside, so that the high heat generated by terminal B cannot effectively circulate with the outside air to assist in heat dissipation
