AI Technical Summary
During long-term use of the power cord, the joint is often required to remain in a bending state because the joint is limited by the docking position, resulting in concentrated stress, which may cause the external insulation layer or internal conductor to break and lose its normal function.
A power cord with an anti-break structure at the end of the power cord is designed. By pre-installing the end sleeve, butt sleeve, tail sleeve and protective ring on the end of the power cord, a protective structure is formed to reduce friction loss and enhance toughness.
It effectively prevents the breakage of the power cord due to friction and bending during use, extends the service life of the power cord, and reduces functional failure caused by friction loss.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power cords, and in particular relates to a power cord with an end anti-breakage structure. Background Art
[0002] Power cords are wires that transmit electric current, usually used to transfer electricity from a power source (such as a socket) to electrical devices (such as TVs, computers, etc.) to enable the normal operation of the devices. Power cords can be divided into AC power cords and DC power cords according to their use. AC power cords are usually used to pass higher voltage alternating current, so they need to be standardized and obtain safety certification before they can be officially produced. DC power cords are usually used to pass lower voltage direct current. Although the safety requirements are not as strict as AC power cords, countries still require unified safety certification.
[0003] During long-term use, the power cord often needs to remain bent due to the limitation of the joint position. This continuous bending will cause the force to be concentrated at the bend. Over time, it may cause the outer insulation layer or even the internal wire of the power cord to break, causing it to lose its normal function. In order to solve this problem, we need to make corresponding improvements and optimizations to this defect of the power cord during use. Utility Model Content
[0004] The purpose of the utility model is to provide a power cord with an anti-breakage structure at the end, aiming to solve the problem that the power cord often needs to be kept in a bent state during long-term use due to the limitation of the joint position. This continuous bending will cause the force to be concentrated at the bent part, which may cause the outer insulation layer or even the internal wire of the power cord to break over time, causing it to lose its normal function. In order to solve this problem, we need to make corresponding improvements and optimizations to this defect of the power cord during use.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a power cord with an end anti-breakage structure, comprising a power cord, one end of the power cord is connected to a first connector, the other end of the power cord is connected to a second connector, and the first connector and the second connector are respectively connected to an end sleeve on the outer wall of the power cord;
[0006] One end of the end sleeve is fixedly connected with a docking sleeve, the other end of the docking sleeve is fixedly connected with a tail sleeve, and the other end of the tail sleeve is bonded with a protective ring.
[0007] In order to enable the docking sleeve to dock with the corresponding first connector and second connector, as a preferred power cord with an end anti-damage structure of the utility model, one end of the docking sleeve is provided with a rectangular opening, and the corresponding first connector and second connector are plugged into the rectangular interior of the docking sleeve.
[0008] In order to enable the butt sleeve and the tail sleeve to be sleeved on the outer wall of the power cord, as a preferred power cord with an end anti-damage structure of the utility model, the central ends of the butt sleeve and the tail sleeve are penetrated by through holes, and the inner diameters of the through holes on the butt sleeve and the tail sleeve are adapted to the maximum diameter of the power cord.
[0009] In order to enhance the toughness of the tail sleeve when it is bent, as a preferred power cord with an end anti-breakage structure of the utility model, a slot is provided between the outer wall of the through hole of the tail sleeve and its outer wall, and an elastic sheet is inserted into the slot.
[0010] In order to simplify the installation method between the slot and the elastic sheet, as a preferred power cord with an end anti-damage structure of the utility model, three slots are opened on the tail sleeve at equal intervals, and the side shape of the slot is a "C"-shaped structure.
[0011] In order to reduce the friction damage between the power cord and the protective ring, as a preferred power cord with an end anti-damage structure of the utility model, an annular wall is provided on the inner wall of the open ends on both sides of the protective ring, and the shape of the annular wall is a funnel-shaped structure.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] Attach the end sleeve, docking sleeve, tail sleeve and protective ring to the end of the power cord in advance, then connect the first connector and the second connector to the power cord, and then connect the two end sleeves to the tails of the corresponding first connector and the second connector respectively, so that the protective ring will remain in the installed position. During use, the friction of the power cord on the annular wall of the protective ring will reduce the damage caused by friction, thereby preventing the power cord and the first structure or the second connector connection end from being damaged by friction.

[0025] Preferably, a rectangular opening is formed at one end of the docking sleeve 5 , and the corresponding first connector 2 and second connector 3 are inserted into the rectangular interior of the docking sleeve 5 .
[0026] During specific use, the docking sleeve 5 is made of insulating rubber material, and the rectangular opening of the docking sleeve 5 is squeezed and sleeved on the corresponding first joint 2 and second joint 3, thereby forming a relatively stable interference connection structure between the docking sleeve 5 and the corresponding first joint 2 and second joint 3.

[0029] When used specifically, before the tail sleeve 6 and the protective ring 7 are bonded together, the elastic sheet 9 is first inserted into the corresponding slot 8 . The elastic sheet 9 is made of metal, and the tail sleeve 6 is made of insulating rubber.
[0030] Preferably, three slots 8 are provided on the tail sleeve 6 at equal intervals, and the side surface of the slots 8 is a "C"-shaped structure.
