Embodiment 1

[0029] Such as figure 1 The shown embodiment is a charging anti-theft cable for digital products, including a twisted wire layer 1, a TPU sheath layer 2, a steel traveler layer 3 and a TPU plastic outer sheath layer 4 arranged sequentially from inside to outside; The line layer includes 3 tinned copper wires 11 twisted together, each tinned copper wire includes a TPEE sheath 111, 150 DuPont fiber filaments 122 distributed along the axis line of the TPEE sheath and surrounding each DuPont fiber 120 tinned copper wires 113 of wire; a lubricant is provided between adjacent layers of twisted wire layer, TPU sheath layer, steel traveler layer and TPU plastic outer sheath layer. The lubricant is talcum powder or lubricating oil; the setting of the lubricant reduces the friction between adjacent layers, and the charging anti-theft cable is not easily damaged.

[0030] Such as Figure 4 As shown, the outer peripheral surface of the inner sheath layer is provided with annular grooves...

Embodiment 2

[0043] Embodiment 2 comprises all structures and method parts in embodiment 1, as image 3 As shown, the outer peripheral surface of the TPU sheath layer in embodiment 2 is provided with 10 grooves 21, and each groove is provided with steel balls 22 arranged continuously, and the steel balls in embodiment 1 are replaced by each steel ball in each groove. Wire ring layer.

[0044] Replace step 400 of embodiment 1 with the following steps:

[0045] The steel balls are closely arranged in each groove, the lower part of the steel ball is located in the groove, and the groove makes each steel ball be restricted in the groove, and each steel ball can roll relative to the groove.

[0046] The high-strength DuPont fiber effectively increases the toughness of the present invention, and improves the bending resistance of the present invention; the tinned copper wire has good conductivity, and is not easy to generate heat after strong charging; the TPU sheath layer has both the elastici...

Abstract

The invention discloses an anti-theft charging cable for a digital product. The anti-theft charging cable comprises a twisted wire layer, a TPU sheath layer, a steel wire ring layer and a TPU plastic outer sheath layer which are arranged in sequence from inside to outside, wherein the twisted wire layer comprises a plurality of tinned copper leads twisted together; each tinned copper lead comprises a TPEE sheath, a plurality of DuPont fibers distributed along an axis of the TPEE sheath, and a plurality of tinned copper wires encircling the DuPont fibers; and a lubricant is arranged between the adjacent layers of the twisted wire layer, the TPU sheath layer, the steel wire ring layer and the TPU plastic outer sheath layer. The anti-theft charging cable has the characteristics of shearing resistance, tension resistance, bending resistance, difficult heating during strong charging, good impact resistance, easy stretching, tearing prevention, high temperature resistance and oxidation resistance.

Description

technical field [0001] The invention relates to the technical field of digital product display, in particular to a shear-resistant, tensile-resistant and bending-resistant digital product charging anti-theft cable. Background technique [0002] The anti-theft charging cable of digital product display equipment is easy to be cut during frequent use, and the internal wire is easily broken or broken after being stretched and bent, resulting in anti-theft failure or false alarm. In a short period of time, the exterior surface is prone to problems such as scratches, damage, and discoloration. Contents of the invention [0003] The purpose of the present invention is to provide a shear-resistant, tensile-resistant, bending-resistant cable that overcomes the shortcomings of the digital display equipment in the prior art that are easy to be cut, poor in tensile properties, or good in strength but not easy to bend. The digital product charging anti-theft cable. [0004] In order ...
