Antistatic structure and antistatic processing method of POS (point-of-sale) machine combined data cable

Abstract

The invention relates to the technical field of data cables, in particular to an antistatic structure and an antistatic processing method of a POS (point-of-sale) machine combined data cable. The antistatic structure of the POS machine combined data cable comprises a middle main cable and two groups of connector cable sets, each connector cable set comprises a power supply cable, an analogue communication cable and a digital communication twisted pair, and the middle main cable comprises two power core wires, multiple analogue communication core wires, an analogue communication conduction ground wire, two twisted pair groups and the like. By the aid of a conduction mode of single-sided conductive aluminum foil and the conduction ground wires, discrete wires of the combined data cable can be subjected to integral anti-static treatment, conduction connection joints are arranged on the internal model of each conduction connecting portion of the combined data cable, grounding treatment with the power ground is performed, finally static electricity is discharged to the ground, the purpose of effectively preventing static electricity from damaging equipment and systems is achieved, the effect of electrostatic protection is realized, mechanical properties of spring wires are unaffected, and high economical efficiency is realized.

Description

[0001] Technical field: [0002] The invention relates to the technical field of data lines, in particular to an antistatic structure and an antistatic treatment method for a combined data line of a POS machine. [0003] Background technique: [0004] In the connector industry, in addition to the functions of normal power supply, digital, analog signal transmission and communication protocol, combined data lines are easily exposed to charged objects such as human bodies with static electricity due to the exposure of connector plugs and wires. The introduction of static electricity into the equipment and system will affect the normal operation of the equipment and even cause damage to the system and equipment. Especially for the combination data line of POS machine, the static electricity protection during operation is directly related to the security of customer account, and its importance is self-evident. [0005] The traditional way to prevent static electricity is to add co...

Problems solved by technology

However, due to the complexity of combining data cables, adding braided shielding layers to some wires such as spring wires will affect mechanical properties such as elasticity and appearance dimensions; connector plugs such as RJ45 crystal plugs do not all have metal iron shells that can be connected to grounding; and The signal ground (virtual ground) of the data line cannot be directly connected to the power ground, etc., and it is difficult to achieve comprehensive electrostatic protection for the combined wire. It is possible to cause static electricity damage in an instant
