AI Technical Summary
Traditional power connectors are prone to metal fatigue deformation after long-term insertion and removal, resulting in insufficient contact, increased resistance, and possible arc discharge, which affects equipment safety and performance.
The plug terminal is designed with an arc-shaped corrugated surface. The upper part of the arc of the plug terminal undergoes slight elastic deformation when inserted, ensuring full contact between the head and the socket contact piece, reducing resistance and increasing current flow.
This achieves a tight connection between the plug terminals, reduces resistance, reduces temperature rise, and improves the reliability and safety of the power connection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of power connectors, and in particular to a novel power connector plug. Background Technology
[0002] Power connectors are used to connect electrical equipment to power cords or data cables. Traditional power connectors typically have flat strip-shaped or cylindrical plug terminals. After repeated plugging and unplugging, these terminals can undergo slight deformation due to metal fatigue, resulting in insufficient contact, increased resistance, and reduced performance. They can even cause arc discharge, generating sparks and damaging electrical equipment. Therefore, they have objective shortcomings in practice. Utility Model Content
[0003] The technical problem to be solved by this utility model is to scientifically design a new type of power connector plug, which transforms the traditional flat strip and cylindrical plug terminals into arc-shaped plug terminals. When the plug is inserted and squeezed, the upper part of the arc of the plug terminal will undergo slight elastic deformation, so that the head of the plug terminal can fully contact the contact piece of the socket, reduce resistance, increase the current flow, and achieve the beneficial effect of tight connection and low temperature rise.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a novel power connector plug, including a base and a plurality of plug terminals; the base is provided with a plurality of mounting holes with one side flat and the other side arcuate; the plurality of plug terminals are all set to be exactly the same shape; the lower part of each plug terminal is set to be arcuate; the neck is set to be slightly thinner; and the head is set to be an integral flat plate.
[0005] The plug terminal has an arched reinforcing rib in the middle of its head.
[0006] Compared with the prior art, the advantages of this utility model are:
[0007] This utility model discloses a novel power connector plug, comprising a base and several plug terminals. Through scientific design, the traditional flat strip and cylindrical plug terminals are transformed into arc-shaped plug terminals.
