Description

Technical Field

[0001] The utility model relates to the field of power cords, in particular to a pressure-resistant power cord. Background Art

[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point to point. The power cord is usually composed of a live wire and a neutral wire. The live wire and the neutral wire are respectively provided with insulating sleeves on the outside. In order to ensure the integrity of the live wire and the neutral wire when used, a thickened insulation layer is usually provided on the outside.

[0025] The utility model provides Figure 1-3 A pressure-resistant power cord shown in the figure includes a power cord body 1, a pressure-resistant insulating sleeve is arranged on the outside of the power cord body 1, the pressure-resistant insulating sleeve is made of rubber insulating material, and the pressure-resistant insulating sleeve has a certain thickness, so as to improve the pressure resistance of the power cord body 1, a plug 2 is connected to the end of the power cord body 1, and a protective component 3 is arranged at the connection between the plug 2 and the power cord body 1, and the protective component 3 includes a first protective shell 31, a second protective shell 32, a first arc plate 33, a second arc plate 34 and a locking component 35, the first protective shell 31 and the second protective shell 32 are sleeved on the outside of the plug 2, and the first arc The plate 33 is fixedly connected to the top of the first protective shell 31, and the second arc plate 34 is fixedly connected to the top of the second protective shell 32. The first arc plate 33 and the second arc plate 34 form a curved pipe to protect the power cord body 1. When the first protective shell 31 and the second protective shell 32 and the plug 2 maintain a relatively stable state, the curved pipe formed by the first arc plate 33 and the second arc plate 34 can perform sleeve protection on the connection between the power cord body 1 and the plug 2 to prevent the connection between the power cord body 1 and the plug 2 from being compressed and bent and damaged. The locking assembly 35 is arranged on the front of the first protective shell 31 and the second protective shell 32.

[0026] Specifically, a hinge 36 is provided on the back of the first protective shell 31, and the first protective shell 31 and the second protective shell 32 are rotatably connected by the hinge 36, so that under the action of the locking assembly 35 and the hinge 36, the first protective shell 31 and the second protective shell 32 can be stably docked and connected to the outside of the plug 2, and the inner walls of the first protective shell 31 and the second protective shell 32 are fixedly connected with a clamping block 38 and a snap-in block 39 for clamping the plug 2. The clamping block 38 is clamped on the outside of the plug 2, and the snap-in block 39 is snap-connected to the top of the plug 2. The clamping block 38 and the snap-in block 39 can ensure the stability of the connection between the first protective shell 31 and the second protective shell 32 and the plug 2.

[0027] In particular, the locking assembly 35 includes a first fixing plate 351, a second fixing plate 352, a connecting plate 353 and a positioning rod 354. The first fixing plate 351 and the second fixing plate 352 are fixedly connected to the front of the first protective shell 31 and the second protective shell 32 respectively.

One end of the connecting rod 356 passes through the fixing ring 358 and is fixedly connected to the limit block 359. The limit spring 357 is located between the limit block 359 and the fixing ring 358. The limit spring 357 can be provided to the connecting rod 356 through the limit block 359 and the connecting rod 356. The plate 353 has an elastic force moving toward the first fixed plate 351, so that the connecting plate 353 drives the positioning rod 354 to maintain a stable clamping state with the second fixed plate 352. A handle 3510 is fixedly connected to one side of the limit block 359. A sliding hole matching the handle 3510 is provided on the side of the first fixed plate 351 away from the second fixed plate 352. The handle 3510 can be used to drive the connecting plate 353 to slide away from the first fixed plate 351, so that the connecting plate 353 drives the positioning rod 354 to separate from the second fixed plate 352.
