Abstract

The invention discloses a plug of a power connector, which comprises an insulation base and at least one conducting unit and is characterized in that the insulation base is an inserting body provided with a plurality of grooves in parallel; the conducting unit comprises two contact terminals in the same shape; the contact terminals are rectangular sheets provided with heat radiating grooves, one end of each contact terminal is provided with a plurality of contact sheets, and the other side is provided with a plurality of pins; the contact sheets and the pins are arranged perpendicularly; and the contact terminals are inserted in the grooves in parallel and in pairs. Compared with the prior art, the invention has the advantages of tight contact, large contact area, small contact resistance and good hear radiation performance, greatly improves the circuit performance in large current transmission, and has simple assembly process.

Description

technical field [0001] The invention relates to electrical components, in particular to a power connector plug suitable for large current transmission between a circuit board or a mother board and a daughter board. Background technique [0002] In the interconnection of electronic circuits, the power connector acts as a bridge to transmit current to each component in the circuit, so the quality of the bridge will directly affect the final performance of the entire transmission circuit. In the power connector, there is a big difference between the contact and the signal contact. The power contact needs to have higher requirements. It not only has a very low contact resistance, a large contact area, and a heat dissipation area. Moreover, when the power contacts are assembled into the insulating base, there must be good heat dissipation and ventilation conditions, so as to meet the heat reduction and temperature rise control in the process of large current transmission, and red...
