[0004] However, when the end of the bolt c squeezes the cable, the wires in the cable are prone to breakage, so that the conductive wires in the cable are reduced, resulting in an increase in the resistance of the cable in the column d
At this time, when the plug is energized, the temperature of the terminal will rise rapidly, which will affect the safety performance of the plug.

Abstract
The invention discloses a plug, relates to the technical field of electric appliances, and is used for reducing the resistance between a cable and a bolt and ensuring the safety performance of the plug. The plug comprises a shell, a plug pin, a support and a wire pressing assembly. The support is fixed in the shell. The plug pin comprises a plug pin body and a wiring part fixedly connected with the plug pin body; the plug pin body is located outside the shell, and one end of the plug pin body extends into the shell. The wiring part is fixed in the support and is provided with a wiring surface.The wire pressing assembly comprises a wiring terminal and a bolt, and a stud of the bolt extends into the support; the wiring terminal is arranged in the support, the wiring terminal is provided with a wire pressing surface, and the wire pressing surface is parallel to the wiring surface and is arranged along the axial direction of the bolt; and the area of the wire pressing surface and the areaof the wiring surface are greater than the end surface area of the threaded end of the bolt. The wiring terminal is connected with the bolt, and the bolt rotates to drive the wiring terminal to movein the axial direction of the bolt.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a plug. Background technique [0002] The plug is an important device for connecting electrical appliances to the power supply. Generally, an electrical appliance is connected to a plug through a power cord, and a conductive cable in the power cord is connected to a pin on the plug. [0003] figure 1 A schematic diagram of the connection between the cable and the plug in the prior art is shown. see figure 1 A terminal d with a through hole b is fixed on the pin a, and a bolt c is threaded on the terminal d, the bolt c is perpendicular to the through hole b, and the end of the bolt c extending into the terminal d can be connected with the through hole The inner wall of the hole b abuts. At this time, it is only necessary to extend the cable into the through hole b, and rotate the bolt c, so that the end of the bolt c extending into the terminal d abuts against t...
