Abstract

The invention relates to the technical field of power lines, and especially relates to a self-locking plug for a power line, and the power line. The plug comprises a plug main body, and the plug main body is provided with jacks, wherein the interior of at least one jack is provided with a self-locking assembly. The self-locking assembly comprises a card, and the card is provided with a through hole. The plug main body is provided with a platform, and one side, of the card, is provided with a first pulling plate. One side, located at the jack, of the plug main body is provided with a cavity, and the first pulling plate is disposed in the cavity. The first pulling plate is connected with one end of the card. The interior of the cavity is provided with a spring, and the platform is provided with an inclined limiting baffle plate. The first pulling plate is connected with a second pulling plate. According to the invention, the plug can achieve the locking of a terminal during connection, thereby enabling the plug not to be plugged out easily. The plug has a self-locking function, is simple and quick in operation, further avoids the misoperation and self-falling, can guarantee the normal operation of corresponding equipment, can avoid electric shock accidents, and is higher in safety.

Description

technical field [0001] The invention relates to the technical field of power cords, in particular to a self-locking plug of the power cord and the power cord. Background technique [0002] The power cord is a common connection line, including a plug, the plug is provided with a jack, and a contact piece is provided in the jack, and the terminals on the power supply of the electrical equipment (such as a host, a display, etc.) are inserted into the jack to contact with the contact Chip contact, so as to achieve continuous power supply. [0003] However, the commonly used power cord plug has a relatively simple structure. During operation, the plug can be disassembled and assembled only through the plugging action, especially when it is pulled out, it can be easily pulled out, which may cause misoperation and low safety. . Contents of the invention [0004] The purpose of the present invention is to provide a self-locking plug and power cord to solve the technical problems...
