Description

Quick-charging steel wire cable for commodity burglary prevention

Technical Field

The invention relates to the field of commodity theft prevention, in particular to a cable which is used for playing a role in signal and/or electric transmission in a commodity theft prevention device in the field of commodity theft prevention.

Background

With the development of commodity experience type services, commodity display and experience functions are more open to purchasers or potential purchasers, and meanwhile, the requirement for commodity theft prevention is also continuously improved. How to meet various demands of experimenters as much as possible, show all functions and the best and convenient side of goods to the experimenters as much as possible, and on the other hand, prevent the possible theft of the ill-centered person, reduce and even stop the possible hidden trouble of being stolen of the goods in the showing and experiencing process as much as possible, and under such industrial environment, the goods anti-theft industry is generated.

Common commodity burglary prevention in the prior art adopts an anti-theft device which is contacted with or connected with the commodity, and when the commodity is possibly at a risk of being stolen, the anti-theft device can send out an alarm or send out an alarm instruction to an alarm so as to prompt staff in a display place. In general, the commodity anti-theft device detects whether a commodity is in a safe state through a sensor, if the sensor detects an unsafe state, a signal can be sent to an alarm device to trigger an alarm, in this case, at least one cable among the commodity, the sensor and the alarm device is connected, generally, the cable can be used for transmitting the signal, in some situations with different requirements, such as the commodity being an electronic product, the cable can also be used for supplying power to the commodity, and in some situations, the cable can also be used for supplying power to the commodity and detecting safety of the commodity.

In practical application, regarding commodity anti-theft, because of different conditions, the demands on commodity anti-theft security level are also different, for example, some commodity anti-theft devices often only require a sensor to separate from commodities, trigger a monitoring device to alarm, so that theft can be prevented in time and salesperson can be reminded of knowing, in some cases, the demands of the commodity anti-theft devices cannot be met by simply relying on an electronic alarm commodity anti-theft scheme, commodity experience is considered and commodity anti-theft security level is improved, for example, the electronic anti-theft device also needs to have certain tensile and shearing resistance to deal with possible theft. In this case, the simplest and most efficient way is: materials such as steel wires or metal hoses are wrapped on the basis of the traditional sensor cable for connecting commodities, so that the anti-theft alarm charging is achieved, and meanwhile, the anti-theft alarm charging has good tensile and shearing resistance, and is a general scheme for the situation in the industry at present.

This solution, while meeting the requirements, also brings some drawbacks, such as: for electronic devices, in order to achieve longer endurance and faster processing speed, a powerful power supply guarantee needs to be provided externally in the process of exhibiting these functions, in other words, an anti-theft device corresponding to these commodities needs to provide a larger charging current to meet the requirement of quick charging, so as to ensure that power exhaustion is avoided in the process of exhibiting, and the user cannot experience the functions or characteristics of the anti-theft device. The anti-theft equipment wire is required to have lower impedance and higher conductive efficiency, so that the core wire is thickened, the peripheral steel wire or the metal hose is wrapped, the whole cable is very thick, the display attractiveness and the environment are influenced, the bending radius of the whole wire is overlarge and is not soft enough due to the rigidity of the steel wire or the metal hose, and the wire can be only made into a linear or larger-radius spring mode, so that the commodity taking or playing experience of a customer is influenced.

Some improvements of the cable in the prior art can expand the function of the cable, for example, chinese patent CN207097518U discloses a stretch-resistant fireproof alarm cable, a fireproof layer and a temperature control cable are designed in the cable, the fireproof alarm sensitivity of the cable is improved in this way, however, the principle and the demand of the fireproof alarm are different from those of the anti-theft alarm, and the fireproof alarm does not need the functions of electric conduction and charging; as another example, chinese patent CN207558457U discloses a wire rope cable, which comprises an outer layer wire rope, an outer sheath, a braided reinforcing layer, an inner sheath, an isolation layer, a filling, an insulating layer, a wire and a reinforcing rubber filling, wherein the reinforcing rubber filling is positioned at the center of the wire rope cable, the insulating layer wraps a plurality of wire cores formed by the wire to surround the rubber filling, the filler is filled around the wire cores, and the isolation layer is overlapped and wrapped on the wire cores and the filling outer layer; in addition, chinese patent CN106057317B is a popular method for charging anti-theft cable for digital products in early years, and reduces the heating phenomenon in the process of transmitting current through dupont fiber yarn and tin-plated copper wire, and protects the wire through a protective sleeve and a bead ring layer, but in practical use, the cable is broken by the tin-plated copper wire part of the inner core after being bent for many times, which results in the reduction of the conductive section corresponding to the broken position of the cable, so that the risk of heating is difficult to avoid when the current is too large.

Disclosure of Invention

The invention aims to solve the technical problems in the prior art, and provides a quick-charging steel wire cable for commodity theft prevention, which can originally overcome the cable use problem in the theft prevention field.

A quick-charging steel wire cable for commodity burglary prevention,

comprises an inner core layer, an isolating layer, a steel wire layer and an outer layer which are sequentially arranged from inside to outside;

the inner core layer comprises at least one wire; the inner core layer is one of the conductive bodies of the present invention, and a common wire, such as the digital product charging anti-theft cable mentioned in the background art, at least needs two inner cores which are electrically isolated from each other to meet the requirement of forming a positive-negative electric path so as to form an electric circuit.

The isolation layer is configured to block the inner core layer from the steel wire layer; the isolation layer is also an insulating layer, and the skin abrasion of the lead wire of the inner core layer in the current transmission process can be avoided through the blocking of the isolation layer, so that the short circuit caused by the contact with the steel wire layer is prevented.

The steel wire layer comprises a plurality of steel wires, the steel wire layer not only plays a role of protecting the inner core layer, but also can serve as another conductive main body corresponding to the inner core layer, generally, the conductivity of the steel wire is inferior to that of a copper wire, but the steel wire has certain elasticity and elasticity, the strength of the steel wire is far higher than that of the copper wire, compared with a softer copper wire, the steel wire can obviously improve the shearing resistance and tensile resistance of a cable, but the steel wire needs to be frequently picked up by a user and experiences and changes various directions as the cable, so that the steel wire needs to have certain flexibility, the diameter of the steel wire can be within 0.2mm in order to solve the problem, and the flexibility of the steel wire can be improved under the condition of keeping the shearing resistance and tensile resistance of the steel wire.

The steel wire comprises an insulating layer; when the steel wire is bent, the positions of metal molecules therein are changed, the bent inner metal molecules are compressed and gathered, and the bent outer metal molecules form uneven heating due to uneven distribution and different states of the metal molecules at the bending place if current passes through the steel wire.

The outer layer is configured to wrap around the steel wire layer, so that the steel wire cable is prevented from leaking out; the outer layer is used for protecting the steel wire and also used for protecting the whole cable, and wraps all the conductive structures in the cable.

Further, the steel wire comprises a conductive layer. In order to improve the conductivity of the steel wire, so that the steel wire is matched with the conductivity of the inner core layer, the steel wire can also be wrapped with the conductive layer, and the conductive layer can be combined to the outer surface of the steel wire to form an integrated wire with the steel wire.

Further, the conductive layer is located between the steel wire and the insulating layer.

Further, the conductive layer comprises one or more of tin, aluminum, copper, silver, gold, and the like.

Through the structure, in the cable, the conductive layer and the steel wire layer are combined through the form of X-coated steel (X=conductive material), so that the conductivity of the steel wire is effectively improved while the flexibility and the strength of the steel wire are maintained.

Further, the steel wire is configured to be distributed around the periphery of the isolation layer.

Further, the inner conductor wire includes a plurality of electrically isolated conductive core wires from each other.

Further, the inner core layer comprises a plurality of strands of reinforcing filaments.

Further, the conductive core wire is rewound with the reinforcing wire. The conductive core wire and the reinforcing wire are combined together by adopting a rewinding process, so that the bending resistance of the lead can be effectively improved.

Further, the wire layer is configured to be able to be used for transmitting signals and/or transmitting power.

Further, the cable can be wound into a spring. The cable structure of the invention can lead the cable to have good elasticity and flexibility while having good conductive performance, so the cable of the invention can be wound into a spring wire for use.

The beneficial effects of the invention are as follows:

(1) Compared with the traditional copper wire and the scheme of wrapping the steel wire with the conductive wire core in the background art, the quick-charging steel wire cable can reduce the bending radius of the cable by at least 20% under the condition of achieving the same electrical performance, has flexibility, and correspondingly prolongs the service life of the cable.

(2) According to the invention, the steel wire layer is used as the conducting layer through the design of the inner core layer and the outer wrapping steel wire layer, so that the inner core layer comprises at least one wire, one path of current (such as current +) can be transmitted, the steel wire can be used as the other wire, and the other path of current (such as current (-for)) can be transmitted, and the inner core layer which originally at least needs to comprise two wires (comprising the insulating layer) can be reduced to one wire through the current transmission mode, so that the diameter of the whole cable is reduced, and the cable can be made finer under the same performance.

(3) The invention adopts the steel wire as one path of wire, in order to solve the problem that the steel wire has residual rigidity and insufficient flexibility, the invention reforms the steel wire into the steel wire with smaller radius, and the steel wire can be more flexible as a whole under the condition of achieving the same shearing resistance and tensile property by a multi-strand winding mode, and can adapt to bending of various shapes, and is manufactured into the spring wire, winding and other using modes.

(4) After the steel wire is made into a thin wire, the cable can be continuously stretched, twisted, bent and the like in the commodity antitheft field during commodity experience, under the circumstance that the cable is frequently broken at a position with more bending, once the cable is broken at a part of the cable core, the cable is heated due to the fact that the radius of the conductive section is suddenly reduced at a bending point when high current passes through the cable core, and even fire hazards can exist in serious cases.

(5) According to the invention, the lower-impedance dielectric layers, such as tin, aluminum, gold and the like, are wrapped on the outer layer of the steel wire, and when alternating current or alternating electromagnetic fields exist in the conductor, the current distribution in the conductor is uneven, the current is concentrated on the skin part of the surface of the conductor, namely a thin layer on the surface of the conductor, so-called current skin effect is formed, in the current skin effect, the closer to the surface of the conductor, the higher the current density is, and the lower the current in the conductor is, namely, when the cable passes through alternating current (such as commodity power supply), the current in the steel wire is concentrated on the surface of the steel wire due to the current skin effect, namely, the wrapped lower-impedance dielectric layer is transmitted, so that the current transmission efficiency on the surface of the steel wire is improved, the conductivity of the steel wire is obviously improved, and the rapid charging of the steel wire is realized. In addition, the electric conductivity of the steel wires is improved, and the number of the steel wires can be further reduced under the condition of meeting the rated current transmission requirement, so that the overall diameter of the cable is further reduced.
