Description

M243765 V. Creation Description (1) [Technical Field to which the New Type belongs] The structure of the coaxial power cord of this creation is mainly improved by twisting the cores in the inner or outer layer (ie, the live or ground) of the coaxial power cord. Formed into several wire strands, and then twisted several wire strands into the inner wire layer (or outer wire layer) again. The design of the wire strand can reduce the overall broken rate of the power line for a long time. [Previous technology] According to the general coaxial power line (see the first figure), it is mainly composed of an outer insulation layer (1 1), outer line layer (1 2) (outer conductor), inner insulation layer (1 3) and inner layer (1 4) (internal conductor), and the inner layer (1 4) is composed of a number of cores (1 4 1) twisted with each other. Although this design has been used for many years, but broken However, the shortcomings of high stock ratios always exist (the breakage rate of general coaxial power cords after Bending Test is less than 30%), and the high stock breakage rate will directly affect the coaxial The overall impedance of the power line (1) results in an increase in the overall temperature of the wire and a decrease in safety and efficiency. In order to reduce the overall stock-breaking rate, general manufacturers usually increase the overall number of shares to reduce the overall stock-breaking rate. This method will increase the overall cost. Therefore, how to reduce the stock breakage rate of the coaxial power cord without the risk of increasing the cost is a necessary and urgent problem. Therefore, based on the above problems, we know that the traditional coaxial power cord has been implemented. The need for improvement. [New content]

Page 5 M243765 V. Creation Instructions (2) "Problems to be Solved" The problems to be solved in this creation are mainly the situation that the core of the coaxial power cord will break after a long period of use (the core The stock-breaking rate is less than 30%). Through the implementation of this creation, the stock-breaking rate can be reduced to less than 5%, so as to improve the overall transmission efficiency and security. "Technical means to solve the problem" The technical means provided in this creation are based on the twisting of the cores in the outer layer and the inner layer (mainly the inner layer) of the coaxial power cord into a number of strands. The strands are twisted together again, and the implementation of power lines with inner and outer layers of several strands can reduce the breakage rate during long-term bending, thereby increasing the overall safety and efficiency. "Effects on the prior technology" Through the implementation of this creation, the following advantages can be achieved over the previous technology: 1. Through the implementation of this creation, the overall stock breaking rate of the coaxial power cord can be reduced (from about < 30% to about < 5%). 2. Through the implementation of this creation, the impedance of the power line can be reduced, thereby reducing the overall temperature generation. 3. Through the implementation of this creation, the overall safety, efficiency, and strength of the power cord can be greatly improved. [Embodiment] An example is given below to explain the structure and operation of this creation in detail.

Creation Instructions (3) Application and Features: Please refer to the second diagram (a) of the embodiment of this creation, which reveals the front and back ends of the coaxial power cord (2) of this creation. It is connected to the power line connection sleeve (3) respectively, and the coaxial power line (2) and the power connection sleeve (3) are connected to each other (A), and the coaxial power line (2) is the most severely broken. Place. Please refer to Figures 3, 4 and 5 for the three-dimensional cut-out schematic diagram, plane cut-out schematic diagram, and inner-layer layer cut-out schematic diagram of this creation. The figure reveals the structural improvement of a coaxial power cord (2) of this creation, mainly It consists of an outer insulating layer (2 1), an outer wiring layer (2 2), an inner insulating layer (2 3), and an inner wiring layer (2 4), of which the outer insulating layer (2 1) and the inner insulating layer (2 3) It is mainly made of insulating materials, and the inner insulating layer (2 3) is between the outer layer (2 2) and the inner layer (2 4), and passes through the inner insulating layer (2 3) and the outer insulating layer ( The setting of 2 1) can cover the inner layer (2 4) and the outer layer (2 2) to insulate the outer layer (2 2) and the inner layer (2 4), thereby preventing the outer layer (2 2) and the inner line. The layer (2 4) interferes with each other to cause a short circuit, and the outer layer (2 2) is mainly composed of a number of cores, while the inner layer (2 4) is composed of a number of strands (2 4 1) (the line strand The number is best implemented with 7 or more), and each strand (2 4 1) is composed of a number of cores (2 4 1 1), which is implemented through the implementation of the strand (2 4 1) Reduce the broken rate when the coaxial power cord (2) is bent for a long time, the arrangement of the strand (2 4 1) is mainly based on one of the strands (2 4 1) as the center, and the other strands (2 4 1) Arranged in a circular shape, while the central strand
