AI Technical Summary
The existing 8-shaped power cords are arranged side by side, so that the pressure is directly applied to the core cords through protection when squeezed, which can easily lead to damage to the core cords.
A pressure-proof loss power cord is designed, and a buffer zone is formed by setting anti-extrusion grooves on both sides of the protection and a pressure-reducing filling strip between the outer protection and the anti-extrusion groove to form a buffer zone to avoid damage to the core wires squeezed against each other.
It effectively avoids mutual extrusion and damage of the core wire when being squeezed, and enhances the anti-extrusion performance of the power wire.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power lines and specifically relates to a pressure loss-proof power line. Background Art
[0002] Existing figure-8 power cords, etc., need to have a flat cross-section due to the fact that the two core wires are arranged side by side. However, most flat wires rely on the pressure-relieving properties of the protective blanket's own material to prevent compression damage. When the two sides are squeezed, the pressure will directly act on the core wire through the protective blanket. Excessive pressure or prolonged pressure will cause damage to the core wire. Utility Model Content
[0003] The utility model provides a pressure loss-proof power cord to solve the above technical problems.
[0004] The solution adopted by the utility model to achieve its technical effect is:
[0005] A pressure loss-proof power cord comprises a connecting wire and a connecting terminal: the connecting wire comprises two core wires, a protective inner quilt, a protective middle quilt and a protective outer quilt; the protective inner quilt is sleeved on the outside of the two core wires; the protective middle quilt is sleeved on the outside of the protective inner quilt; anti-extrusion grooves are arranged on both sides of the protective middle quilt; the protective outer quilt is sleeved on the outside of the protective middle quilt; the connecting terminal is arranged at both ends of the connecting wire.
[0006] Preferably, an I-shaped pressure relief piece is arranged inside the protection; grooves on both sides of the I-shaped pressure relief piece are respectively sleeved on the outside of the two core wires.
[0007] Preferably, a pressure-relieving filling strip is provided between the anti-extrusion groove and the protective outer cover.
[0008] Preferably, the outer side of the protective outer cover is provided with a friction-resistant braided sheath.
[0009] Preferably, the connecting end includes an input end and an output end; a plug-in sheath is provided on the outer movable sleeve of the plug of the input end.
[0010] The beneficial effect of the utility model is that a buffer zone is formed between the anti-extrusion groove on the outside of the protective middle blanket and the protective outer blanket on both sides of the two core wires. When both sides of the power cord are squeezed, the pressure can be effectively transferred to the protective outer blanket and the protective middle blanket, avoiding the core wires from being squeezed against each other and damaged.

DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. It should be noted that when an element is referred to as "fixed on" or "set on" another element, it can be directly on the other element or there may be a centering element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be a centering element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolting or gluing.
[0015] Please refer to Figure 1-2 In a preferred embodiment of the utility model, a pressure loss-proof power cord is disclosed, comprising a connecting wire 1 and a connecting terminal 2: the connecting wire comprises two core wires 3, a protective inner sheath 4, a protective middle sheath 5 and a protective outer sheath 6; the protective inner sheath 4 is sleeved on the outside of the two core wires 3; the protective middle sheath 5 is sleeved on the outside of the protective inner sheath 4; anti-extrusion grooves 7 are arranged on both sides of the protective middle sheath 5; the protective outer sheath 6 is sleeved on the outside of the protective middle sheath 5; the connecting terminal 2 is arranged at both ends of the connecting wire 1.
[0016] Specifically, an I-shaped pressure relief piece 8 is arranged inside the protective quilt 5; grooves on both sides of the I-shaped pressure relief piece 8 are respectively sleeved on the outside of the two core wires 3. When the two sides of the power cord are squeezed, the I-shaped pressure relief piece 8 can prevent the two core wires 3 from squeezing each other, and can also reduce the squeezing force on the power cord from the upper and lower directions.
[0017] Specifically, a pressure-relieving filling strip 9 is provided between the anti-extrusion groove 7 and the protective outer jacket 6 to further enhance the anti-extrusion performance of both sides of the power cord.
[0018] Specifically, the I-shaped pressure relief piece 8 and the pressure relief filling strip 9 are both made of TPE elastic material.
[0019] Specifically, the outer side of the protective outer cover 6 is provided with a friction-resistant braided sheath 10, and the friction-resistant braided sheath 10 is a nylon braided sheath.
[0020] Specifically, the connection terminal 2 includes an input terminal and an output terminal; a plug-in sheath 11 is provided on the outer movable sleeve of the plug of the input terminal.
[0021] It can be seen from the above description that the utility model can effectively protect the inside of the power cord.
